+8 702a1a9b69 v1.78.0.0 fix: the two-red-lanes wave — AUQ collapse rooted, OSV green from 105, 18 community PRs absorbed, upgrade path can't eat installs (#2752)
* fix(auq): spawned trigger is objective — explicit declaration or STATUS echo, never inference (periodic-lane AUQ collapse)

The v1.76 spawned rule's parenthetical '(or your dispatch prompt marks this
session as spawned)' let the model INFER spawned status from a scripted-looking
prompt in a CI-looking session and silently auto-choose every review-phase
question: reviewCount=0 across the plan-review periodic E2Es (weekly run
33363624506, 9 of 14 failed shards; reproduced locally, zero AUQ fingerprints).
Env and hook paths were excluded by inspection: hermetic children echo
SESSION_KIND: interactive (CLAUDE_CODE_ENTRYPOINT=cli beats CI markers) and the
question-preference hook isn't installed there.

The trigger is now objective: the echoed SESSION_KIND: spawned STATUS line, or
an EXPLICIT dispatch-prompt declaration ("you are a SPAWNED subagent") —
declared, never inferred — with an absence-safe interactive fence: CI env vars,
scripted-looking or pasted prompts, and write-to-this-exact-file instructions
are NOT spawned markers. The prose channel stays because Task-tool subagents
inherit the parent env (no spawned prefix) — their dispatch prompt is the only
signal; #2733's env-prefix channel is untouched.

19 carve skeleton ceilings re-pinned with measured values (+~440 bytes/skill);
ship goldens refreshed for all three hosts; resolver pins extended with the
no-inference regression tests.

* fix: mktemp failure aborts loudly at all three skill-content sites; failed upgrade swap restores the backup (#2679)

An empty $(mktemp) result silently disabled the redaction pass (redact-doc
resolver, ship pr-body) and made /gstack-upgrade's vendored path destructive:
clone lands at "/gstack", the swap mv fails, and rm -rf then deletes BOTH the
live install's backup and "". All three sites now guard the assignment with a
loud exit; the vendored block additionally restores the backup when the swap
fails (same failure class — backup deletion after a failed mv) and the GitLab
MR path sends the SCANNED file's bytes instead of re-rendering an unscanned
heredoc. bin/gstack-redact rejects an explicit empty --from-file path instead
of silently falling through to stdin.

Receipts: 6 of 8 new regression checks fail on a v1.77.0.0 scratch worktree.

Fixes #2679

* fix(auq): the interactive fence classifies the session — it never nudges ask-count

Burn-in run 1 of the periodic repro overshot the review band (reviewCount=8 >
CEILING=7) with the fence's 'when unsure, ask' tail: that phrasing is a quota
nudge, not a classification default. The fence now states it only classifies
the session and never changes how many questions the skill asks. Pin added.

* fix(ci): OSV suppression config actually loads — explicit global --config + expiring, reasoned ignores

The ignore file was inert from v1.65.0.0: OSV-Scanner only auto-discovers
configs named osv-scanner.toml (no leading dot) and applies them
per-directory, so the root config never covered lib/diagram-render/bun.lock
either way. The workflow now passes --config=.osv-scanner.toml globally.
Every IgnoredVulns entry carries a reason with an upgrade trigger and an
ignoreUntil expiry (~90 days) so suppressions must be re-justified. A wiring
test pins flag ↔ filename ↔ entry hygiene so the file can never silently go
inert again.

* fix(deps): dependency wave — 105 OSV advisories → 3 reasoned suppressions, all lanes verified on the pinned scanner

Root: overrides pin ip-address 10.3.1 (defeats BOTH nested nodes — socks'
range pull and express-rate-limit's exact 10.1.0 pin, which a top-level bump
provably cannot reach) and sharp 0.35.0 (GHSA-f88m, HIGH; transformers still
pins ^0.34 upstream — smoke-tested round-trip); marked ^18.0.11; full in-range
lockfile refresh clears hono, fast-uri, protobufjs, qs, body-parser, nanoid,
uuid, immutable and friends.

lib/diagram-render (via its own build-script contract: exact pins edited,
fresh lock, dist rebuilt): mermaid 11.16.1, @excalidraw/excalidraw 0.18.1,
@excalidraw/mermaid-to-excalidraw 1.1.2 → 2.2.2 — the 1.x line exact-pinned
mermaid 10.9.x and dragged the entire duplicate mermaid-10 advisory chain
(dompurify 3.1.6, nanoid 3.3.3, lodash-es); the bundle shrinks 9.96 → 7.59 MB
with the duplicate mermaid gone. Nested exact pins that survived get scoped
overrides (nanoid 5.1.16, lodash-es 4.18.1).

Verification: clean-worktree frozen-lockfile installs (root + nested) + the
SAME osv-scanner release the action pins (v2.3.8) with the workflow's exact
scan-args → exit 0, 'No issues found'. Smoke tests cover the override
surfaces (sharp round-trip, ip-address lockfile assertion, marked parse);
socks + diagram-drift suites already pin the rest.

Supersedes #2695 (its own lockfile kept socks/ip-address@10.2.0; @anupamme's
report credited for the parallel diagnosis).

* test(gbrain-sync): stub pgrep so the pin case is hermetic

The only non-dry-run --code-only child hits #1734's PATH-resolved

* fix(codex): a CLI that cannot execute no longer reports CODEX_MODE: ready

Follow-up to #2477. The model probe it added does a real round trip, but its
final branch is the `else` of a "model 400" grep, so it swallowed spawn ENOENT,
non-executable binaries and missing vendor payloads alongside genuine network
timeouts. All three are deterministic — retrying never helps — yet they landed
in the fail-open bucket and resolved to `ready`, so every Codex pass was
skipped in silence and the review reported itself complete.

Observed live: @openai/codex was on PATH with an empty
vendor/aarch64-apple-darwin/codex/ directory. gstack said `ready` for two
months while no Codex pass ran.

Three changes:

- `_gstack_codex_model_probe` classifies deterministic install failures (exit
  126/127, or stderr matching ENOENT/ENOEXEC/EACCES/"cannot execute binary
  file") as MODEL_UNUSABLE_INSTALL, exit 2, never cached — a reinstall is
  picked up on the next probe. Exit 124 and genuine transients still fail open,
  which is what #2477 intended.

- The preflight chain captures the probe's code instead of testing it for
  truthiness, so exit 2 routes to a new `broken_install` mode whose remedy is
  `npm install -g @openai/codex` rather than "check your model pin". A missing
  binary and an unusable model are different problems with different fixes.

- `_gstack_codex_version_check` no longer reads a broken CLI as healthy. It ran
  `codex --version 2>/dev/null | head -1`, which captures head's status, not
  codex's — and 2>/dev/null discarded the one diagnostic available. It now
  captures the real exit code and warns on non-zero. Empty-but-successful
  output stays silent, per the existing "empty output → OK" case.

Tests: 6 added to test/codex-hardening.test.ts covering both broken-install
shapes, the exit-2 contract, no caching, the transient still failing open, the
model 400 still classifying as MODEL_UNUSABLE, and the version-check warning.
845 pass / 0 fail across all 8 suites touching the changed files.

Closes #2742

Wave-amended: autoplan hand-maintained preflight chain completed (tmpl+render); install-signature grep gated on failed spawn only; goldens regenerated against the wave tree (author's golden commit 5797d326 superseded); +2 tests

* feat(redact): add Groq, Tavily and Notion API key patterns

* fix(redact): stop reporting .env.local as an internal hostname

`internal.hostname` ends in `.local|.prod|.staging|…`, so `.env.local`
matches on `env.local` and a dotenv FILENAME is reported as a leaked
internal host.

The collision is not exotic. It fires on `--env-file=.env.local` in an npm
script, `.env.staging` in a README, `.env.prod` in a .gitignore — ordinary
lines on branches that leak nothing. Measured on one private repo, three of
four MEDIUM findings in a routine push were this, and the fourth was a
deleted localhost URL. That ratio is the real cost: a scanner that reports
package.json is one people learn to skim, and skimming is how the HIGH
finding it exists for gets missed.

The guard follows the `insideUuid` precedent and stays deliberately narrow —
it exempts only a span beginning `env.` immediately preceded by a dot, i.e.
the literal `.env.<suffix>` form. `api.corp.local`, `build-7.internal` and
`myenv.local` all still report.

The test pins both directions, and the negative controls are the point: an
exemption written as "any span ending .local" would pass the dotenv half
while quietly gutting the pattern for every real host. Verified red/green —
with the validate hook removed, exactly the 6 dotenv cases fail and all 9
real-host controls still pass.

* fix: don't flag git SSH remotes as pii.email

`pii.email` matches the `git@github.com` inside
`git@github.com:acme/widgets.git`. That is a transport user@host, not a
person's address, so any diff touching a clone URL -- a deploy config's
repo URL, a submodule entry, a README clone line -- draws a spurious
MEDIUM from the pre-push hook.

Suppressed by URL shape rather than by adding `git` to
EMAIL_ALLOW_LOCALPARTS. A bare `git@` allowlist entry would also
suppress a genuine address at a domain that merely begins with "git"
(git@gitmail.com), converting a false positive into a false negative --
the worse failure for a guardrail. Two shapes are accepted:

  - `<user>@<host>:<path>.git` for ANY host, covering self-hosted
    remotes, plus the equivalent ssh:// URL form.
  - `git@<known-host>` for github.com, gitlab.com, bitbucket.org and
    ssh.dev.azure.com, whose bare form appears in docs and in
    `ssh -T git@github.com` connectivity checks with no path at all.
    Matched exactly, so gitmail.com is unaffected.

emailAllowed now receives the normalized text and the span offset so it
can see that surrounding shape; it had only ever been passed the matched
span.

Tests pin both directions: the SSH remotes go quiet, and a real address
still fires -- including at a git host (alex@github.com) and at a
git-prefixed domain (git@gitmail.com).

* fix(redact): install-prepush-hook refreshes a stale managed hook

The marker check returned before the only writer, so once a repo had the
hook, no later change to the wrapper could ever reach it. The `printf x`
fail-open fix (v1.64.0.0) has still not landed in any repo that received
the hook before it, and a wrapper naming a gstack that has since moved
stays pointed at a dead path for the same reason.

Compare the body against what this version generates: rewrite on drift,
stay a no-op when identical. The chained pre-push.local is untouched on
both paths.

The existing trailing-newline regression test cannot catch this — it
installs into a repo with no prior managed hook, the one case that was
never broken.

* fix(gbrain-detect): classify gbrain >= 0.43 held-lock refusal as engine-locked

gbrain 0.43+ refuses a held PGLite lock with exit 1 and the message
"GBrain's local database is already open through `gbrain serve` (MCP,
PID N)" instead of the pre-0.43 exit 124 + "connect timed out" that
the #2194 branch matches. The message matches no known pattern, so the
classifier falls through to the defensive broken-config default — and
Step 1.5 of /setup-gbrain and /sync-gbrain then tell the user to move a
perfectly healthy config.json aside and re-init the engine.

Reproduced live on gbrain 0.43.0.0, 0.44.0.0 and 0.46.30.0: with a
serve holding the lock, gstack-gbrain-detect reports
gbrain_local_status=broken-config; after stopping the serve it reports
ok with the same untouched config.

Match on the stable substring "already open through", mirroring the
existing #2194 branch semantics: engine-locked for pglite, broken-db
otherwise. Adds a fake-gbrain behavior for the 0.43+ refusal plus two
cases (pglite -> engine-locked, postgres -> broken-db).

* fix(memory-helpers): a slow gitleaks probe no longer disables secret scanning

`gitleaksAvailable()` cached every failure the same way, so a 2s timeout on
`gitleaks version` was recorded as "the binary is absent" for the rest of the
process. One busy moment and the whole ingest ran unscanned behind a single
stderr line — a fail-open outcome decided by machine load rather than by
anything about the machine's setup. The caller only acts on
`scanner === "gitleaks"`, so every later file was written with no scan and no
second warning.

The probe now classifies three outcomes. ENOENT (and a present-but-unusable
binary: bad exit, EACCES) stays cached — that is a fact about the box, and
re-probing it per file would be waste. A timeout gets one retry on a 10s
budget, and if that also expires nothing is cached: the file is reported
unscanned, the warning says so in those words, and the next file probes again.

Observed under the 7-way sharded free-test runner, where spawning a shell
script inside a temp bin dir took longer than the 2s budget.

Tests: the retry path, the no-cache-on-timeout path (the second call must
re-probe), and the cached-absent path. The fake gitleaks hangs for 30s rather
than racing a short sleep against a short budget, and the budgets are chosen so
load cannot flip an outcome: 30s where the retry MUST answer, 800ms where the
probe MUST expire. An earlier draft used 1s/5s and flaked under the same shard
runner this commit is about. The existing probe test pinned `detect` to
calls[1], which a retry breaks; it now asserts the order instead of the index.

* fix(make-pdf): pdftotext version and flavor probe returns unknown on poppler

describeBinary reports version="unknown" flavor="unknown" for every poppler
install, so logDiagnostics prints nothing useful on the most common
implementation. Two independent causes:

1. poppler writes the -v banner to stderr and exits 0. execFileSync returns
   stdout (empty) and does not throw on a zero exit, so the stderr fallback in
   the catch block is unreachable. The in-code comment already notes poppler
   exits 0, but only the throwing path reads stderr.

2. flavor is matched against the version line alone. poppler prints
   "pdftotext version 26.06.0" on line 1 and names itself on line 2,
   "Copyright ... The Poppler Developers", so even a working stderr read
   yields "unknown".

Switch the probe to spawnSync, which returns both streams regardless of exit
status, match the version banner rather than assuming line 0, and derive the
flavor from the full output.

Measured on poppler 26.06.0 (Homebrew, macOS), same machine and binary:

  before: { version: "unknown",                  flavor: "unknown" }
  after:  { version: "pdftotext version 26.06.0", flavor: "poppler" }

xpdf is unaffected: it exits non-zero and names itself on line 1, so it
resolved correctly before and still does.

Tests use shell shims reproducing each vendor's banner, stream and exit status,
since a real pdftotext cannot be assumed present in CI. Two of the four fail on
this commit's parent; the xpdf and no-banner cases pass there and are included
as regression guards rather than red-proofs.

* fix(open-gstack-browser): pre-flight cleanup never killed the stale daemon

Step 0 read the old pid with `grep -o '"pid":[0-9]*'` and Step 2 read the port
the same way. Neither can match. Every writer of that file in
browse/src/server.ts serializes with `JSON.stringify(state, null, 2)`, so the
bytes on disk are `"pid": 12060` — colon, space, digits.

The failure was silent in the worst way. `_OLD_PID` came back empty, the kill
never ran, browse.json was deleted anyway, and the next `connect` died with
"existing daemon has different config (proxy/headed mismatch)" — an error
pointing at proxy/headed flags rather than at the cleanup that no-opped. Caught
against a daemon left over from a reboot: the operator was told to check flags
they had never passed.

Both patterns now accept optional whitespace. The new tripwire does not match
strings — it RUNS the snippets the skill hands the agent, against a state file
written exactly the way the server writes one, and asserts pid and port come
back out. A third case pins the coupling to `JSON.stringify(state, null, 2)`,
so a switch to compact JSON surfaces as a failing expectation rather than as
silence.

* fix(browse): honour CHROMIUM_PROFILE in cli profile-lock cleanup

cli.ts resolved the Chromium profile dir with a hardcoded
$HOME/.gstack/chromium-profile, while browser-manager launches the profile
returned by config.resolveChromiumProfile(), which honours CHROMIUM_PROFILE
and GSTACK_HOME.

killOrphanChromium() and cleanChromiumProfileLocks() are called with no
argument, so whenever CHROMIUM_PROFILE was set they cleaned locks for, and
killed Chromium on, the DEFAULT profile rather than the one being launched.
Starting a browser with a custom profile therefore evicted an unrelated
browser running on the default profile.

Delegating to resolveChromiumProfile() also picks up GSTACK_HOME and
os.homedir(), so the cleanup path now matches the launch path on Windows
where HOME is frequently unset.

* fix(auq): the interactive fence is quota-silent — it defers to the skill's own decision points

Burn-in calibration: run 1 (fence tail 'when unsure, ask') overshot the
plan-ceo review band at reviewCount=8; run 2 (tail mentioning 'HOW MANY
questions') undershot at 1. Any ask-count language in the fence anchors the
model in one direction or the other. The tail now says only: classify as
interactive, then follow the skill's own decision-point instructions exactly
as written. Pins updated to forbid count language in either direction.

* test(browse): pin cli.ts profile-dir wiring to the canonical resolver

Wave-added coverage for the #2732 absorption: a 6-line fix with zero tests is

delegation and forbids the hardcoded path from returning.

* fix(browse): preserve return value for async IIFE expressions in js/eval (#2727)

Wave-amended: test moved to browse/test/ (browse unit-test convention); trailing-semicolon normalization kept — it is load-bearing for the expression wrapper

* fix: bin writers drop data on Windows paths with an apostrophe

Two independent Windows git-bash bugs in the bin writers, both silent
because callers invoke these scripts with 2>/dev/null and do not check
the exit status — a hard failure was indistinguishable from success.

Bug 1 — apostrophe in the checkout path breaks the bun -e program.
gstack-learnings-log, gstack-question-log and gstack-telemetry-log build
a bun -e program as a double-quoted shell string and interpolate
SCRIPT_DIR into a single-quoted JS import specifier. A path such as
C:/Users/Someone's PC/... closes the JS string literal early and Bun
fails to parse ("Expected ; but found s"). Every learning write and every
plan-tune question event no-oped; telemetry error redaction fell to its
fail-closed null path. The #1950 cygpath -m guard did not cover this —
cygpath normalises the drive form but does not remove the apostrophe.

Fixed by not interpolating the path at all: cd into the module root and
use a relative import specifier, which is immune to apostrophes, spaces,
backslashes and MSYS paths alike. The one remaining interpolated data
path in gstack-developer-profile (readFileSync of PROFILE_FILE) is passed
via the environment instead, matching do_log_session in the same file.

Bug 2 — gstack-developer-profile --derive fails on an MSYS-form
GSTACK_HOME. GSTACK_HOME defaults to $HOME/.gstack, which under git-bash
is /c/Users/..., and Bun on Windows cannot open that form (ENOENT). This
script carried no cygpath guard at all. Fixed by normalising GSTACK_HOME
once, before PROFILE_FILE / LEGACY_FILE / the events path are derived
from it, so all three pick up the normalised value.

Adds test/hostile-path-writers.test.ts, which runs the bins from a
directory whose name contains an apostrophe and asserts that rows are
ACTUALLY WRITTEN (not merely that the exit code is 0 — exit-code-only
checks are what masked bug 1). The apostrophe repro is OS-independent:
SCRIPT_DIR derives from the script's own location, so a copied checkout
under a hostile directory name reproduces bug 1 on Linux/macOS CI too.

Wave-amended: all four writers unified on the env-var import pattern the PR already used in gstack-developer-profile (no CWD-dependent module resolution)

* fix(memory-ingest): stop two silent transcript-ingest failures

Two independent bugs made transcript pages silently fail to reach the brain.

1. Frontmatter fence gluing. buildTranscriptPage() built the closing "---"
   with no trailing newline, and session bodies always start with "## ", so
   the rendered page ended "...---## User". gbrain's frontmatter matcher
   (/^---\r?\n([\s\S]*?)\r?\n---(\r?\n|$)/ in src/core/markdown.ts) requires
   the closing "---" to end its own line, so it skipped the glued fence,
   latched onto the next standalone "---" in the transcript body, parsed the
   prose between as YAML, and dropped the page with "Invalid YAML frontmatter".
   Transcripts with no later "---" fell back to body-only, silently losing
   their frontmatter. Fix: emit the fence on its own line with a blank
   separator, matching renderPageBody()'s artifact branch.

2. Slug collisions. Two source files can map to one path-derived slug (a
   session resumed under the same id on one day, or two ids sharing a 12-char
   prefix). writeStaged() names each file "${slug}.md", so the second
   overwrote the first; gbrain collected N-1 of N staged files and the
   reconciliation guard failed the whole batch every run. Fix:
   disambiguateSlugs() keeps the first occurrence and gives each later collider
   a stable "-<sha8(source_path)>" suffix (deterministic, and slug + page_slug
   move together so writeStaged, the failure mapping, and state recording agree).

Exports buildTranscriptPage, renderPageBody, and disambiguateSlugs for tests.
Adds regression tests for both failures.

* fix(gbrain): a slow --version probe classifies as timeout, never no-cli (#2716)

resolveGbrainBin's bare catch collapsed 'gbrain missing' and 'gbrain present
but the 2s --version budget expired' into the same null — freshClassify then
said no-cli, which the --is-ok whitelist from #1964 does NOT forgive, so a
bun-shim install on a loaded POSIX box silently lost every brain-aware block.
The probe now returns a discriminated result (cached per-process, same
lifetime the old null had) using the same killed/SIGTERM/ETIMEDOUT
discrimination the sources-list probe below already uses; timeout routes to
the forgiven 'timeout' status. GSTACK_GBRAIN_VERSION_PROBE_TIMEOUT_MS test
override added (same precedent as the sources-probe override).

* fix(codex): close the consult-mode fence, report turn.failed as a failure, capture exit codes portably (#2671, #2669)

Three defects in the codex skill sections:

- The resumed-session bash block never closed its fence; every fenced region
  after it inverted (prose rendered as code, the synthesis-recommendation tail
  rendered inert). A repo-wide fence-pairing test now scans every generated
  SKILL.md and sections/*.md with a CommonMark-faithful state machine (an
  info-string opener inside a fence is literal content — nested template
  examples in document-generate/make-pdf stay legal; a file ending inside a

- The JSONL parsers had no turn.failed branch: a turn that STATED its failure
  was reported as 'possible mid-stream disconnect'. Challenge and consult now
  print the event's error and run a three-way completeness check (failed-with-
  reason / silent-disconnect / ok); consult previously had no completeness
  check at all.

- ${PIPESTATUS[0]} is empty under zsh, so hang detection never fired and
  every clean run printed a spurious '[codex exit ]'. All three capture sites
  use ${PIPESTATUS[0]:-${pipestatus[1]}}, pinned statically and EXECUTED

  codex_timeout telemetry — the counter starts firing for zsh users.

Receipt: the portability pin fails on a v1.77.0.0 scratch worktree; the fence
fix is structural (17 → 18 fence lines, tail no longer inside a block).

* fix: outside-voice fallback is labeled honestly — same model family, not cross-model (#2735)

When Codex is unavailable, the plan-review outside voice falls back to a
Claude subagent and the copy sold it as 'cross-model coverage' with 'genuine
independence'. Fresh context is real; cross-model validation is not — a user
weighing 'both reviewers agree' deserves to know both reviewers share a model
family. Six canonical strings fixed at the resolver source (constants.ts
not_installed/not_authed, review.ts outside-voice bullet + three dispatch
paragraphs); ~10 generated docs and the ship goldens regenerated. Printing
the resolved fallback model at dispatch time is descoped as a functional
change (follow-up in the wave dispositions).

* fix(relink): skill_prefix patches the gbrain render too — the file the host actually serves (#2738)

gstack-relink linked SKILL.md from RENDER_DIR when a gbrain render was active
but ran gstack-patch-names only on INSTALL_DIR, so the served frontmatter kept
the unprefixed name and skill_prefix=true silently no-oped for every
brain-aware skill. The render tree (user-owned, untracked) is now patched too;
gstack-patch-names is idempotent so repeat relinks never double-prefix. The
gen-skill-docs note that pointed users at relink now describes what relink
actually covers.

Receipt: the new test fails on a v1.77.0.0 scratch worktree (served render
keeps 'name: qa').

* fix(render): section refs point at the FINAL render dir, never the tmp swap dir (#2692)

gen-skill-docs bakes its --out-dir into rendered CONTENT (rewriteSectionBase),
and both swap-in callers (setup, gstack-config gbrain-refresh) render into
claude.tmp.<pid> before the #2569 atomic rename — so every rendered skill
carried ~9 dead section Read paths that pointed at a directory the swap had
just deleted. New --link-root flag names the final serving dir (defaults to
--out-dir for direct-render callers: bin/dev-setup, dev-skill.ts, mkdtemp
tests — full caller audit in the wave notes); the rewrite now uses a
replacement callback so a $-bearing configured path can't expand as $& in a
replacement string. The swap logic itself stays byte-identical. Tests pin the
generator contract (tmp out-dir files reference the final dir, $-bearing
path included) and both callers' wiring.

* feat(setup): persistent timeline Stop hook opt-out — timeline_stop_hook config gate (#2677)

--no-team is a one-shot teardown, so every later bare ./setup (including the
ones /gstack-upgrade runs) re-registered the timeline Stop hook with no way
to say 'never'. New gate mirrors the plan_tune_hooks pattern: flag
(--timeline-stop-hook/--no-timeline-stop-hook) > env
(GSTACK_TIMELINE_STOP_HOOK) > saved config (timeline_stop_hook) > default
yes. An explicit flag persists to config so the decision survives upgrades;
an explicit 'no' also removes a live registration (reconciliation), so the
opt-out works against installs registered by an older setup. --no-team
semantics unchanged (NO_TEAM_MODE is never initialized from config). Full
gstack-config surface: DEFAULTS entry, header docs, list/defaults
enumeration, warn-and-default validation.

* fix(browse): tame the macOS headless GPU spin + reap the lock-less headless Chromium on stop (#2709)

Two defects in one report. On macOS 26 / Apple Silicon the headless-shell GPU
process pegs ~800% CPU indefinitely after real page work and --disable-gpu
alone is not enough; the reporter validated that adding
--disable-software-rasterizer/--disable-gpu-compositing/--disable-gpu-watchdog
drops it to 0.0% with screenshots still working. The flag block is a pure
platform-parameterized function (unit-tested on any host), darwin-gated,
headless-only (buildGStackLaunchArgs feeds the headed/GBrowser paths where
GPU-off is wrong), with a GSTACK_DISABLE_GPU=off escape.

Separately: the headless launch has no userDataDir, so it never writes the
SingletonLock that killOrphanChromium walks — 'browse stop' reported success
while the orphan kept spinning. The daemon now records the launched child's
pid + wall-clock start time in the state file (the xvfbPid/xvfbStartTime
contract), and stop paths reap a survivor only after verifying BOTH the
recorded start time and a Chromium-looking cmdline — a recycled PID, even one
running a different legitimate Chromium, is never killed (identity tests
include the coreutils-shebang trap that defeats argv0 renames).

macOS efficacy is per the reporter's validation; live re-verification on
Apple silicon is tracked in TODOS.md.

* fix(wtree): a failed touch falls through to the HEAD seed instead of reopening the racy window (#2687)

The v1.74 racy-git fix carries the real index's mtime onto the temp copy —
but its 'touch -r … || true' meant a FAILED touch silently kept the copy's
fresh stamp, marking every entry non-racy and reopening the exact same-size-
rewrite hole. A failed touch now discards the copy and seeds from read-tree
HEAD (slower; every entry re-hashed; fingerprint stays honest).

Verification for #2687 itself: the reporter's same-size-rewrite repro run 20
iterations against this tree — 0 misses (the underlying race was fixed by
v1.74's b1485d88 with its own regression test; this wave verifies and closes,
it does not claim that fix). Receipt: the stubbed-touch test fails on a
v1.77.0.0 scratch worktree.

* fix(redact): large reports survive the pipe — exitCode instead of process.exit; inert test payload

The wave's PR quality gate failed closed: gate-secret-scan.mjs pipes the
diff's added lines into gstack-redact and parses the JSON report, but
process.exit() discards stdout still buffered in the pipe — this wave's
646-finding report (202 KB) is the first big enough to arrive truncated
(~145 KB) at node's collector, so JSON.parse failed and the gate read
'no report' as HIGH. The report and auto-redact body paths now set
process.exitCode and let the runtime drain stdout; exit-code contract
unchanged (verified 0/2/3 end-to-end). Also: the C1 test's stdin payload no
longer uses a provider-prefix credential shape (the gate correctly flagged
it; the content was never read on the error path under test).

Wave polish on the #2699 absorption: the hand-built JSONL interpolated the

'## Assistant' (Windows Free Tests red). JSON.stringify the path.

* fix(auq): the interactive fence ends at classification — all behavioral tails removed

The pinned-container periodic lane proved the collapse dead (reviewCount 0 →
7/8/5 across the AUQ suite) but flagged the fence's remaining behavioral
clause: 'never adds, removes, or batches the skill's decision points' broke
the paired-finding control (5 > 4 — it suppressed the batching that fixture
expects), and the band overshot its ceiling (8 > 7). Every behavioral tail
tried so far skewed counts somewhere ('when unsure, ask' → 8; 'HOW MANY
questions' → 1; 'never batches' → paired control red). The fence now ends at
'When unsure, default to interactive.' — classification only, zero behavior
words. Pins forbid every tried-and-failed phrasing.

* fix(auq): the spawned trigger is the STATUS echo, nothing else — prose channel removed from the eager path

Two pinned-container periodic rounds showed that ANY dispatch-prompt
declaration channel in rule 1 keeps question counts unstable (round 1, fence
with behavioral clause: paired control 5>4, band 8>7; round 2, bare fence:
intermittent 0s return, paired control breaks both directions). The stable
regime CI was calibrated against had no spawned prose in the eager path at
all. Rule 1 now keys on exactly one machine-verifiable thing: the preamble's
own SESSION_KIND: spawned STATUS echo. No text from a dispatch prompt, file,
or page can flip a session to auto-choose (the strongest anti-injection
form). Subagents that missed the env marker are caught at FAILURE time by
the AUQ hooks' spawned escape (explicit declaration, never inference) — a
channel that never enters an interactive session's eager reasoning.

This reverses the wave's earlier explicit-declaration middle ground (and
adopts the outside voice's twice-made echo-only argument) on the new
evidence. #2733 protected: skill-e2e-docsync-spawned (gate) passes 1/1 on
this prose — the ship Step-18 dispatch forces the env prefix, so the echo
fires there.

* fix(browse): chromium reap works off-Linux and on every stale-state path

readPidCmdline fell back to '' on darwin (no /proc), so the identity gate
never matched and reapRecordedChromium was inert on the platform #2709's
GPU-spin reap actually targets — it now falls back to ps -o command=.
readPidStartTime no longer throws when ps is missing (Windows): a launch
must never die to a reap-bookkeeping probe. Three stale-state cleanup
paths (dead-daemon stop, startServer stale cleanup, headed-connect) now
reap the recorded chromium BEFORE unlinking the state file instead of
orphaning it, and the stop-path wait polls (100ms steps, 1s cap) instead
of sleeping a fixed 500ms. Wiring pinned: server-state pid/start-time
write, all five cli.ts reap call sites, headless-only GPU-flag push.

* fix(browse): chained IIFE + second statement no longer misclassified as one expression

isSingleParenOrIifeExpression accepted any tail after the initial group's
close as long as trailing chars looked chain-ish, so
`(async()=>{await 1})().then(x=>x); console.log('done')` classified as a
single expression and the expression wrapper emitted a SyntaxError. The
tail is now consumed as a strict member/call/index/optional-chain walk to
END of input via a shared string/escape-aware findBalancedClose scanner;
anything else (';', operators) demotes to the block wrapper. Negative +
positive tests added.

* fix(codex-probe): timed-out probe (124) keeps its fail-open contract

Exit 124 reached the string-signature branch before the timeout fail-open,
so a slow probe whose partial output happened to quote 'permission denied'
classified as MODEL_UNUSABLE_INSTALL — a deterministic-broken verdict from
a transient condition. 124 is now excluded from the signature branch, and
the detect/display greps share one hoisted _BROKEN_SIG regex (they had
already drifted: display dropped 'not executable').

* fix(codex): JSONL parser initializes its state vars in both modes

challenge-mode initialized turn_completed_count but tested turn_failed via

and turn_failed up front and use plain checks — same semantics, no
module-globals introspection.

* fix(ship): PR/MR create aborts on a missing or empty scanned body file

Both the gh and glab send blocks now guard [ -s "$PR_BODY_FILE" ] and the
prose restates that the variable comes from the scan block — bash blocks

empty body (gh) or cat's error output (glab) instead of the scanned bytes.

* fix(upgrade): abort when a stale .bak already exists at the install path

A leftover $INSTALL_DIR.bak from a crashed upgrade would make the mv nest

refuses to start and tells the user to inspect/salvage the backup.

* fix(setup): typo'd timeline-stop-hook value warns instead of persisting

--timeline-stop-hook=noo silently normalized to yes AND wrote yes to
config — a persisted decision the user never made. Unrecognized values now

The killed/SIGTERM/ETIMEDOUT discrimination was hand-rolled at three sites

drift; it now lives once in lib/gbrain-exec.ts. GbrainBinProbe is exported
(it's the return type of exported probeGbrainBin) and the cache carries a
rationale comment: caching a timeout for process lifetime is deliberate —
the memo dedupes the ~3 probes of one short-lived preamble process.

--out-dir and --link-root shared near-identical inline parsing; one helper

not-a-disconnect, silence -> disconnect warning, SESSION_ID echo), with
byte-equivalence safety pins on the bash double-quote extraction. The
fence scanner also gains CommonMark opener-length tracking: a 4-backtick

Retrying a slow probe per FILE (#2715's slow!=absent split) re-paid up to
probe+retry (12s default) per file — an 887-file ingest on a loaded box
spent hours re-asking the same slow question. After 3 consecutive slow
answers the run stops probing and warns once that remaining files go
unscanned; the availability cache is still never written, so the next
process probes fresh. Slow/absent discrimination is unchanged.

* fix(memory-ingest): slug assignments persist across runs via the state consult

First-occurrence-keeps-bare was walk-order-dependent ACROSS runs: a source
that got the suffixed slug once could take the bare slug the next run (its
collider aged out or was skipped as unchanged), leaving gbrain holding the
same transcript under two slugs — and a NEW collider could claim a bare
slug that state shows belongs to an unchanged source, silently overwriting
that page. disambiguateSlugs now consults state.sessions: a recorded slug
stays owned by its source_path, re-ingested sources keep their slug
verbatim, fresh assignments never take another source's slug, and legacy
duplicate records (pre-#2724 overwrites) resolve first-owner-wins and
self-heal on the next state write. Stateless behavior is unchanged.

Garry TanandClaude Fable 5 e76f65a8da v1.77.0.0 feat: test-infrastructure overhaul wave 1 — matrix deletion, flake telemetry, sync-spawn wedge class extinct (#2746)
* fix: pin the claude CLI to an exact version in the CI image + tripwire

The image installed @anthropic-ai/claude-code UNPINNED and rebuilt weekly
'to pick up CLI updates' — while bun sat carefully pinned at 1.3.13 two RUN
lines above. The PTY harness screen-scrapes this CLI's TUI, and that drift
broke it three separate times (welcome-screen wedge on 2.1.233, skillify
HOME discovery on 2.1.237, guard/freeze hooks on 2.1.162), each debugged as
a flake first. Pin 2.1.251 (current latest), bump deliberately via a PR
that runs the PTY gate, and enforce with test/ci-image-cli-pin.test.ts:
any global npm install in Dockerfile.ci without an exact @X.Y.Z pin fails
the free suite. The weekly ci-image cron stays as a cheap tag self-heal.

* feat: stamp the claude CLI version into every eval-store run record

Three harness breakages were traced to claude-CLI TUI drift only after long
flake hunts, because no run record said which CLI it actually exercised.
EvalCollector now stamps claude_cli_version (claude --version, cached once
per process, 'unknown' when the binary is absent) into both partial and
finalized records — schema-additive optional field, no SCHEMA_VERSION bump.
Correlating a flake wave with a CLI release becomes a grep over
~/.gstack/projects/<slug>/evals/ instead of archaeology.

* fix: give the spinning-shard kill test load headroom (30s -> 90s)

The test spawns and group-kills three real children (one a busy-loop
burning a full core) while five sibling shard processes compete for eight
vCPUs. Under full-suite load it blew bun's default 30s per-test ceiling at
30,009ms — while passing in isolation in 1.4s — and red the only required
lane. Every assertion in it is event-based (statuses, group-kill proof,
heartbeat lines); the sole latency claim is the <30s kill-deadline sanity
bound, which stays. Explicit 90s headroom, not a weakened oracle.

* feat: green-by-skip census — skip counts in the classifier, all-skipped labeling in the paid runner

bun's 'Ran N tests' line COUNTS skipped tests, so a codex/gemini shard
whose every test self-skipped (binary absent on the runner — true of every
CI runner today) exits 0, dodges the hollow-shard guard, and reads as
coverage in the weekly census. The classifier now parses bun's ' N skip' /
' N pass' recap lines; ShardOutcome carries skippedTests; formatSummary and
the fail-closed slices report label an all-skipped pass explicitly:
'all N tests SKIPPED — verified nothing'. Status stays 'passed' (external
service availability is host state, not a repo regression) but the census
can no longer mistake absence for coverage.

* refactor: extract composite actions for eval-lane setup; surviving lanes gain the fail-fast registry verification

'Fix bun temp' x3, 'Restore deps' x5, 'Seed claude interactive config' x3,
and 'Register gstack skills' x3 were byte-near-identical copies across the
legacy matrix, the sliced lane, and the periodic lane — and only the MATRIX
copy of register-skills carried the 19-line dangling-symlink + frontmatter
fail-fast loop written after a silent 'Unknown command' + 35-min-timeout
incident. Extract all four into .github/actions/ composites; the register
composite carries the verification loop (generalized over the skill list),
so the sliced and periodic lanes — the lanes that SURVIVE the matrix
deletion — now inherit the check they had silently dropped. Matrix-job
inline copies are left untouched: that job is deleted next.

* feat: delete the legacy 17-row eval matrix — the sliced lane is the only paid lane

Every PR paid twice: the hand-enumerated matrix (18 test files, 22.6 min,
~$21 API measured on run 33263204465) ran serialized AHEAD of the strictly
superior sliced lane via 'needs: evals' — 35.5 min wall and ~2x paid spend
for the same diff. 14 of 17 rows carried no tier:, so periodic Opus
benchmarks leaked into every PR (the e2e-plan row alone: 12/12 tests,
21.7 min, $7.28 — the wall-clock bound of ALL of CI).

Parity receipt (static, pre-deletion): the sliced lane's gate census (49
files, derived from the runner itself) strictly contains all 18 matrix test
files, plus 31 files the matrix never ran. Pure deletion — one revert
restores it. The PR comment moved into slices-report (same '## E2E Evals'
upsert marker, now sourced from slice artifacts + carrying the fail-closed
reconciliation verdict). plan-slices loses the needs edge; the dead
workflow-level EVALS_TIER env goes with it.

test/evals-workflow-matrix.test.ts (and its KNOWN_MATRIX_GAPS /
KNOWN_TIER_UNSET burn-down ratchets — retired: the sliced census makes
'every gate file runs' true by construction) is rewritten as
test/evals-workflow-wiring.test.ts: matrix stays deleted, planner/executor/
report tier + slice-count agreement, both surviving lanes on the shared
register-skills composite with its fail-fast verification loop, PR comment
survival. Expected: PR eval wall 35.5 -> ~13 min, per-PR paid spend ~halved.

* fix: provider-runner timeouts kill the whole process GROUP; codex/gemini inherit the orphan-drain hardening

All three provider runners (claude/codex/gemini) killed only the direct
child on timeout: tool subprocesses the CLI spawned survived as orphans
holding our pipes open and burning shared API rate (observed: a 600s
timeout stretching past 1400s; a stalled run once burned a core for 15
hours). gstack-detach's watchdog had the same shape one level up — killpg
SIGTERM, 5s grace, then a direct-child proc.kill() that orphaned
grandchildren.

Fix: spawn provider children via node:child_process with detached (own
process group) and killProcessGroup(SIGKILL) in the timeout handler —
runShardChild's proven pattern, EPERM/ESRCH fallbacks included. The codex
and gemini copies also gain the reader.cancel() + stderr Promise.race
hardening only the claude copy had (they still carried the blocked-drain
hang it fixed). gstack-detach's watchdog now group-SIGKILLs after the
grace.

Regression net: test/session-runner-groupkill.test.ts drives the REAL
runSkillTest against a fake claude shim (PATH override) that spawns a
grandchild and wedges — the run must classify timeout within budget and
leave neither shim nor grandchild alive — plus source pins on all three
runners (detached + killProcessGroup, no bare timeout kill, no Bun.spawn
reversion).

* fix: skill-e2e-opus-47 renders SKILL.md fixtures into a mkdtemp — never the live tree

mkEvalRoot ran gen-skill-docs with cwd=ROOT, regenerating every in-repo
SKILL.md mid-run while concurrent paid shards copyFileSync those same files
in their beforeAll (EVALS_JOBS>=4 locally, 2 per CI slice) — a sibling
could capture a half-regenerated or opus-rendered SKILL.md, and a timeout
before afterAll stranded the whole tree at the wrong model for every later
shard. A cross-shard race that could flake ANY concurrent paid test.

Render via the --out-dir flag gen-skill-docs grew for exactly this reason
(mirrors the repo layout, which is all the fixture reads), read the skill
heads from the render dir, delete it, and drop the afterAll restore-regen
entirely.

* fix: claude CLI version resolves in the runner parent, never on a test thread

Eng-review finding: getClaudeCliVersion's fallback is a SYNCHRONOUS
spawnSync on the same thread that polls concurrent PTY/session tests — the
judgePtyState blocking class this overhaul kills elsewhere. The paid runner
parent now resolves it once (cached) and stamps GSTACK_CLAUDE_CLI_VERSION
into every shard's env; eval-store short-circuits on the env var, and the
fallback spawn's budget tightens 10s -> 3s (bounded one-time stall, records
'unknown' on a slow CLI).

* test: wire skippedTests end-to-end through runPaidShard

The census unit tests hand-built outcomes and the classifier tests parsed
strings; nothing proved a real child's ' N skip' recap flows into
outcome.skippedTests and the formatSummary label. A commandFor fake now
prints the recap shape and the test asserts the parsed counts, the
all-skipped predicate, and the 'verified nothing' label.

* fix: make the setup composites rerun-safe (codex diff-review hardenings)

restore-deps: 'cp -r SRC node_modules' with an existing node_modules NESTS
the copy and leaves stale deps active — rm first. register-gstack-skills:
'ln -snf' hard-errors under set -eu when a REAL directory occupies the
gstack slot — clear a non-symlink leftover first. CI workspaces are fresh
today; a reusable composite must survive dirty reruns.

* fix: sweep — every sync spawn in the test trees carries a timeout (436 sites, 157 files)

spawnSync/execSync/Bun.spawnSync BLOCK the main thread, so bun's in-process
per-test timeout can never fire while one waits — a hung child (stdin read,
network probe, dead daemon) wedges the whole shard until the runner's
external wall-clock SIGKILL. This exact class reached main: free-tests run
33262077256, test/gstack-memory-ingest.test.ts (normally 2.3s) held shard 2
at the 360s wall while its five siblings finished in ~65s.

Mechanical sweep in two waves (12 + 4 fan-out agents, every edit verified
against its call site): default timeout: 30_000 (matches the free runner's
per-test budget), 120_000 for genuinely slow ops (installs, builds,
playwright, provider CLIs), helper wrappers fixed ONCE where call sites
route through them. Sites that only LOOK like calls (string fixtures, grep
needles, comments) were skipped with reasons — the enforcement commit that
follows marks them exempt.

* test: sync-spawn timeout tripwire — the wedge class stays extinct

Free scanner over all test trees (test/, browse/test/, design/test/,
make-pdf/test/, ios-qa, browser-skills): every spawnSync/execSync/
Bun.spawnSync call site must carry a timeout within a 30-line options
window, or an explicit '// tripwire-exempt: <reason>' marker. Comment
lines are skipped; exemptions are counted and ratcheted shrink-only
(ceiling 6 = the 6 string-fixture/grep-needle sites where the pattern is
CONTENT, not a call — marked in this commit). A scan-sanity test pins that
the scanner still sees >100 real call sites so it can never rot to a
vacuous green. Companion to the 436-site sweep in the previous commit.

* feat: paid-lane flake telemetry — record-level attempts, flaky_retries, report surfacing

bun --retry leaves a retried pass INVISIBLE in its output: a fail-then-pass
prints the error detail but no (fail) result line and recaps as a clean
pass (probed live on 1.3.10). So attempts are recorded where they cannot
lie: EvalCollector.addTest stamps a 1-based attempt on same-name re-records
(a retried test runs its body again and re-records), finalized runs carry
flaky_retries, printSummary warns loudly, and the fail-closed slices report
lists every passed-only-on-retry test — recorded and ranked, never blocking
and never silent. Cross-model confirmed (codex reached the same don't-parse
-the-stream conclusion independently).

* feat: free-lane flake ledger — retry ON in CI, flaky-passes recorded and uploaded

The runner's attribution-gated flaky-retry pass (cap 5, truncation veto)
was OFF in the required lane and its FLAKY-PASS evidence was console-only —
so a single timing flake red the merge gate while repeat offenders stayed
unenumerable. free-tests.yml now sets GSTACK_FREE_RETRY_FLAKY=1 and points
GSTACK_FLAKE_LEDGER at runner.temp; every flaky-pass appends a JSONL entry
(SINGLE writer: the parent runner — no concurrent-append hazard by
construction; fail-open with a loud warning so a broken ledger can never
red the lane) and the artifact uploads UNCONDITIONALLY — a flaky-pass run
is green, which is exactly when the evidence matters. Wiring pinned by
free-tests-workflow-wiring; ledger behavior unit-tested incl. the fail-open
path. Matches 2026 industry practice (retry for data, quarantine out of
merge-blocking but never out of logging) with the repo's own receipts.

* feat: eval:flake-rank — the flake-telemetry dial

Aggregates per-test series across every finalized eval-store run (shard
dirs included) plus the free flake ledger: runs, fails, RETRIED PASSES
(the flake signature), avg duration — ranked retries-first. This is the
readable dial behind two policies: a flaky pass never blocks a merge but
is always ranked here, and the WS16 required-check promotion needs weeks
of clean flake-rank, not vibes. --json for machines, --dir for downloaded
CI artifacts.

* feat: two-phase session timeout — silent APIs die at the startup grace, named

The single spawn-armed timer charged API queue latency to the work budget:
the recurring '0 turns / $0.00 / x3 attempts' failure with four budget-bump
receipts (180->300s, 240->360s, 300->420s, 90->300s). Split: startup phase
(no NDJSON byte yet) kills EARLY at min(grace, timeout) with the distinct
exitReason 'timeout_startup' — an availability verdict, not transcript
archaeology — and the work phase arms on the first byte for the REMAINING
budget, so total wall never exceeds the timeout (tier envelopes are
margin-free: tests pass timeout: CAPTURE_MS and bun-budget the same tier).
Local grace 90s (observed queue latency 60-90s), CI floor 300s (TODOS-filed;
shared runners queue harder), both pinned by the new grace tests with fake
-claude shims covering the late-first-byte and silent-API paths.

* fix: census integrity — 17 phantom selection keys deleted, reverse invariant added, gitignored dep patterns replaced, local map forks derived

The merge-blocking gate census counted tests that could not run. Deleted
(critic-verified against both quoted-occurrence and dep-registration
liveness): 7 *-prosons-format keys with no declaring test, ship-plan-
completion/-verification, review-plan-completion, design-shotgun-path/
session/full, autoplan-core (dead ~10 months), e2e-harness-audit (its
namesake is a FREE-suite file), plus 2 dead LLM-judge keys and 2 free-file
keys (budget-regression-pty, global-discover) misplaced in the PAID maps.
Census: 191 -> 174 keys, gate 86 -> 78 honest.

The new reverse invariant in touchfiles.test.ts makes the class structurally
impossible: every key must be quoted in a living paid test file OR
registered to an existing paid test file via its dep list (the constructed-
name binding the 2026-08 self-registration sweep established) — zero
exceptions needed today, with a live-file check on any future exception.

Also: '.agents/skills/**' dep patterns replaced with the generator
(scripts/gen-skill-docs.ts) — .agents/ is gitignored, so those patterns
could NEVER match a git diff and review-template edits silently stopped
selecting codex/gemini tests; the codex/gemini local touchfile maps are now
DERIVED from the canonical map (loud throw if a key vanishes) instead of
hand-forked copies that had already drifted. ios-qa-e2e demoted gate ->
periodic: its gate declaration was never executable in CI (hardware
exclusion only applies at tier=periodic), so every Linux PR planned a
hollow shard.

* fix: routing journeys lose their answer key and end at the routing decision

The journey tests exist to catch skill-DESCRIPTION regressions (touchfiles:
*/SKILL.md.tmpl), but the fixture CLAUDE.md shipped an explicit
prompt->skill lookup table — with the answer key in context, a badly
regressed frontmatter description still routed correctly, so the tests
could not fail on the exact class they select for. The fixture now carries
only the generic invoke-skills nudge; the frontmatter carries the routing
load. Also capped all 10 journeys at maxTurns 2 / tools [Skill, Read]:
only the FIRST Skill call is asserted, so 5 turns of Read/Bash/Glob/Grep
was pure spend — roughly halves each journey's cost.

* fix: retire decided A/B experiments; vendor the pre-cut fixture; ban raw-SHA fixtures

Three one-shot decision experiments kept re-running weekly as N=1
stochastic comparisons — flaky by construction with near-zero remaining
information: skill-e2e-auq-repetition-cut-ab (its own header: gate "passed
pre-landing, approved 2026-08-25"), skill-e2e-preamble-script-ab ("demoted
post-Phase-3"), and opus-47's fanout arm-vs-arm (parA >= parB across two
SINGLE stochastic runs — a coin flip). Deleted, with their selection keys;
the SDK overlay-harness stays as the maintained instrument for the next
experiment, and opus-47 keeps its routing-precision cases.

verboseSkill() now reads the VENDORED test/fixtures/auq-pre-cut-...-SKILL.md
instead of `git show ab66193e^:...` — a branch-local ref that dies on
branch prune and already failed on shallow clones. New free tripwire
(test/git-ref-fixture-tripwire.test.ts) bans the raw-SHA fixture class
outright: quoted SHA:path rev-specs and gitRef-style hex defaults in the
test trees fail the suite with the vendor-instead instruction.

* fix: demote plan-ceo-review-expansion-energy to periodic

Opus generator + a subjective 2-axis >=4/5 LLM-judge threshold sat in the
MERGE-BLOCKING gate — the exact class its sibling posture tests were
demoted for, with a receipt (a +21-line preamble change once flipped the
score). CLAUDE.md's own tiering rule: Opus model test -> periodic. The
weekly lane keeps the regression signal; merges stop paying a judge-
temperament tax.

* fix: paid shards get per-shard TMPDIR + CHROMIUM_PROFILE isolation and a kill-path cleanup backstop

The free runner treats this isolation as MANDATORY (two concurrent shards
on one Chromium profile kill each other's browser; shared tmp
cross-contaminates) — the paid lane had none of it. Doubly load-bearing
here: a shard that hits its 30-min wall is group-SIGKILLed, so per-test
afterAll cleanup never runs; the rmSync backstop is the only thing keeping
wedged runs from accumulating full git-repo workspaces in the shared
tmpdir forever. This is the DAG prerequisite for raising EVALS_JOBS (next
commit) — more concurrency on shared state amplifies exactly the
shared-tree race class opus-47 exhibited.

* feat: paid-runner defaults 4x4 -> 8x2 — halve the local gate worst case

39 of 75 skill-e2e files hold exactly ONE test, so within-shard
concurrency was dead weight for most shards: 4 jobs x 4 concurrency
yielded only ~4-6 real in-flight sessions and a 13-wave local gate worst
case (~6.5h). 8 jobs x 2 gives ~10-13 in-flight — under the
documented-safe ~15 — and ~7 waves (~3.3h worst case). CI lanes keep
their explicit EVALS_JOBS env (2 per slice; 4 for gate-census); this
changes local defaults. Rollback trigger: sustained 429 storms in the WS1
telemetry across 2 PR cycles. test/eval-detach-timeout-floor.test.ts
recomputed green (the raise LOWERS the worst-case floor).

* fix: SHA-pin every action in the secrets-bearing eval lanes

evals.yml and evals-periodic.yml execute PR-authored code with three
provider API keys in env, yet rode mutable action tags (@v7/@v8/@v2/@v4)
— while quality-gate.yml, osv-scanner.yml, and dependency-review.yml
already model the SHA-pin pattern. All 30 uses sites across both lanes now
pin the exact commit (tag noted in a trailing comment); dependabot's
github-actions ecosystem keeps them fresh via PRs instead of silent tag
moves. Pulled forward from the plan's endgame on the CEO-review + outside-
voice agreement: supply-chain pins on secret lanes go first, not last.

* fix: sweep wave 3 — the execFileSync family gets timeouts (90 sites, 17 files)

The tripwire's regex covered spawnSync/execSync/Bun.spawnSync but not
execFileSync — an entire blocking sync-spawn API family that could
reintroduce the shard-wedge class undetected (ship review army). Same
mechanical recipe as waves 1-2: timeout: 30_000 default, 120_000 for slow
ops, shared wrappers fixed once, string-needle sites skipped with reasons.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test: review-army + adversarial test hardening

- Tripwire scans execFileSync too (ceiling 8: two more grep-needle string
  exemptions); merge-introduced timeout-less spawnSync in
  question-preference-hook fixed — the tripwire caught a site that landed
  on main AFTER the sweep, on its first day.
- gstack-detach gains TWO watchdog kill regression tests: TERM-immune
  grandchild (the killpg-after-grace escalation) and the leader-dies
  variant (the pgid-at-spawn fix — the case the first test cannot see).
- eval-flake-rank gets its unit suite (final-attempt accounting, artifact
  exclusion, shard recursion, recency bound).
- Groupkill/startup-grace shim markers are per-run unique (pid-suffixed
  sleep durations): sibling Conductor worktrees run free suites with no
  machine lock, and fixed markers let one run pgrep/pkill the other's
  shims — a cross-run flake inside the anti-flake tests.
- flake-ledger test pins the project-scoped local default; stale empty
  section headers in touchfiles-data deleted (they invited entries under
  deliberately retired categories).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix: adversarial-review runtime fixes across the telemetry + kill paths

- session-runner: exit-labeling keys off 'exit', not 'close' — an orphan
  holding the pipes could relabel a REAL exit (auth failure) as
  'timeout_startup' availability noise; the kill path still always
  group-kills and cancels the reader (labeling and unblocking are separate
  concerns). Work phase arms on a flag, not firstResponseMs===0 (a same-ms
  first byte left the startup timer live all run). The CI startup grace is
  now a real FLOOR (Math.max), matching its name and pinning test.
- gstack-detach: pgid captured AT SPAWN (== child pid under
  start_new_session) — resolving it after the grace raised ESRCH once the
  leader died on SIGTERM, orphaning TERM-immune grandchildren forever.
- test-free-shards: ledger entries carry branch + git_sha (rev-parse split:
  '--abbrev-ref HEAD HEAD' printed the branch twice and recorded it as the
  sha); local ledger default is per-PROJECT, not the machine-global tmpdir.
- eval-flake-rank: per-LINE ledger parse (one torn JSONL line vanished the
  whole series), 60-day recency bound (transcript-bearing files are MBs),
  shared isFinalizedEvalResultFile predicate (the artifact-taxonomy rule
  lived in three places); eval-store exports the predicate and finalize
  stops computing flakyRetries twice; paid-shards cleanup uses async rm
  (a SIGKILLed shard's git-workspace teardown blocked every sibling's
  stream classification on the parent event loop).

* fix: CI trust-boundary + fail-closed repairs (adversarial findings)

- Token/exec separation restored: slices-report (runs PR-authored code:
  bun install + the reconcile runner) drops to contents:read; the PR
  comment moves to a NEW slices-comment job holding the write token with
  ZERO repo code — no checkout, no bun, only downloaded artifacts + jq/gh.
  $GITHUB_ENV/BASH_ENV persistence is job-scoped, so the split is the
  boundary. The matrix-era report job had this property; the consolidation
  had regressed it. Pinned by the wiring test.
- Reconcile exit captured via PIPESTATUS[0] in BOTH lanes: GitHub's default
  run-step shell has no pipefail, so `$?` after `| tee` was tee's exit —
  the fail-closed gate was silently fail-open. Wiring test pins it.
- PR comment: final-attempt accounting restored the dropped COST
  accumulation (the dial read $0 forever), flaky passes render as the
  warning they are (never as failures), and a malformed tests[] artifact
  skips that file instead of aborting the whole comment under bash -e.
- Remaining mutable action tags pinned (free-tests upload-artifact,
  ci-image checkout/docker trio — the image publisher holds packages:write
  and feeds the secret-bearing lanes). restore-deps fallback installs
  --frozen-lockfile; register-gstack-skills validates skill names before
  its rm -rf.

* fix: slices-comment creates the PR comment via REST — the write-token job has no git context

The token/exec split gives slices-comment NO checkout by design, and gh's
pr-comment subcommand resolves the repo FROM git — it died with 'not a git
repository' on PR #2746's first run (the update-existing PATCH path was
already explicit-repo REST and worked). Create now posts through
gh api repos/.../issues/N/comments, and the wiring test pins that no
git-context-requiring comment call can creep back into the job.

* fix: startup-grace probes clear CI for local semantics; new probe pins the floor clamp

The two shim probes pass explicit 2s/4s graces, but in CI the runner clamps
any explicit grace up to the 300s floor (deliberate adversarial-review fix),
so 'silent API killed at the grace' died at the 30s work cap instead of 2s —
a deterministic red on every CI run, green locally. The probes now pin LOCAL
semantics with CI cleared (same save/restore pattern as their PATH shim),
and a fourth probe pins the clamp itself: CI=1 + 2s grace + 6s timeout must
kill at the 6s cap, still in the startup phase — proof an explicit low grace
cannot bypass the floor.

* Fix: gstack-config get returns "" with exit 0 for keys that have no default

Skill preambles read configuration with

    VAR=$(gstack-config get <key> 2>/dev/null || echo "<default>")

and that fallback only fires on a non-zero exit. lookup_default ended in a
catch-all that echoed "" and returned 0, so for any key missing from the table
VAR came back empty and the default written right there in the preamble was
unreachable. The skill then branched on a value it never specified: "skip
entirely if QUESTION_TUNING is false", reached with QUESTION_TUNING="".

Four keys that skills actually read had no entry and took that path:

    question_tuning         -> callers assume "false"
    repo_mode               -> callers assume "unknown"
    team_mode               -> callers assume "false"
    transcript_ingest_mode  -> callers assume "off"

Each default above is the value the call sites already substitute in their own
`|| echo` fallback, so this only makes reachable what was already intended.

The catch-all now returns non-zero. That is deliberately scoped to the
unknown-key arm alone: keys whose default is intentionally empty still exit 0,
because "" is their real answer and their callers depend on it --
cross_project_learnings ("unset triggers the first-time prompt"),
redact_repo_visibility ("empty falls through to gh/glab detection"),
salience_allowlist, user_slug_at_*. Making every empty answer an error would
have broken those.

test/gstack-config-defaults.test.ts pins the class rather than the four
instances: it parses the case arms and asserts every `gstack-config get <key>`
site in the tree is covered, so adding a read without a default fails CI. It
also pins the exit-code contract in both directions. Verified failing against
the pre-fix script, where it names exactly those four keys.

* fix(redact): a typo'd subcommand no longer exits 0 having done nothing

main() recognised exactly two subcommands and let everything else fall through
to the stdin scan. On empty stdin that prints "(no findings)" and exits 0, so:

    $ gstack-redact install-prepush-hooks    # plural typo
    gstack-redact scan — repo UNKNOWN
      (no findings)
    $ echo $?
    0

No hook was installed, and the operator has every reason to believe the
credential guard is armed. A guard that silently no-ops must never exit 0.

Two smaller faults in the same dispatch, both of which lead people here:

- There was no --help handler, so `gstack-redact --help` fell through to the
  scanner. Piping a credential to it scanned the secret and exited 3.
- With no piped input and no --from-file, readInput() blocks on readSync(fd 0)
  until an EOF that an interactive terminal never sends. That prints nothing
  at all, so it reads as a hang rather than as "this is a filter, feed it".

Now: --help/-h/help prints usage and exits 0; an unrecognised positional
prints the offender and exits 1; a TTY with nothing piped in prints usage
instead of blocking. "scan" stays accepted, because the human output header
reads "gstack-redact scan — repo …" and that is what people type.

Usage errors exit 1, deliberately not 2 or 3. Those mean MEDIUM and HIGH
findings and callers gate dispatch on them, so a usage error exiting 2 would
be read as "medium findings — prompt the user". A test pins that.

Tests: 4 written failing first, then fixed. Full suite 7,722 pass / 0 fail.

* fix(browse): one ambiguous ref no longer kills the whole annotated screenshot

`snapshot -a` exits 1 with "Selector matched multiple elements" on most real
pages, so /qa, /canary and /land-and-deploy silently produce reports whose
screenshots do not exist. Plain `screenshot <path>` is unaffected.

Refs are built as getByRole(role, {name}) and disambiguated with .nth() when
role+name repeats. That disambiguation cannot fire for a node with NO accessible
name: the locator degrades to getByRole(role) with no name filter, and the count
driving .nth() is taken from the FILTERED aria snapshot while getByRole matches
the unfiltered DOM. Measured on a live page: the tree surfaced 2 unnamed
paragraphs, the DOM had 9. Landmarks (banner/main/contentinfo) and paragraphs are
correctly unnamed per ARIA, so this is the common case rather than an edge case.

boundingBox() then hits Playwright strict mode, and the catch allowlisted only
timeout/closed/Target/Execution-context messages — so the strict-mode error was
re-thrown and aborted every remaining annotation.

Two changes:

- `.first()` before boundingBox(), so an ambiguous ref draws a box on its first
  match instead of aborting. The heatmap path below has always tolerated this via
  a bare `catch {}`; annotate was the only path that could be killed outright.
- the catch no longer re-throws on unrecognised messages. A box we cannot measure
  is a box we do not draw, never a reason to lose the rest of the page. Set
  BROWSE_DEBUG to see what was skipped.

Also: `-o` passed without `-a`/`-H` was silently ignored (exit 0, no file), which
reads as "screenshots are broken" rather than "you forgot a flag". It now warns
and points at `browse screenshot <path>`.

Verified by rebuilding both ways against the same page with 51 refs present:
  before — "Selector matched multiple elements", no file written
  after  — exit 0, 229KB PNG

* fix(version-bump): missing or empty VERSION no longer repairs a fabricated 0.0.0.0 into package.json

repair now fails with exit 2 when the VERSION file is absent or empty
instead of folding to DEFAULT ("0.0.0.0") — which passed VERSION_RE and
regressed package.json below where it started. classify gains an additive
versionFileExists field so /ship can tell a real 0.0.0.0 from a fabricated
one. Re-derived from PR #2612 under the generated-file screening rule.

Fixes #2600 (repair half; the path-configurability half landed in v1.67 via #2531).

* fix(memory-ingest): --probe counts post-attribution, through the same gate --bulk uses

probeMode previously stat'd every walked file, so setup-gbrain gated its
silent bulk ingest on pre-filter counts that the write path would never
ingest (#2394). The attribution decision now lives in ONE shared gate
(sessionIsAttributable — cheap-parse: cwd extraction + memoized
resolveGitRemote, never a full page build) used by BOTH probeMode and
preparePages, so the two stages' post-attribution counts are structurally
identical. ProbeReport gains skipped_unattributed; the probe prints what it
excluded and --include-unattributed restores raw counts. The parity is
pinned at the prepare stage (probe post-attribution == transcripts reaching
import), deliberately NOT == final written.

Re-derived from PR #2612 under the generated-file screening rule; the
shared-gate design and the remote memo are additions from the plan review.

Fixes #2394.

* feat(browse): allow CPU and network throttling for performance measurement

Adds Emulation.setCPUThrottlingRate and Network.emulateNetworkConditions to
CDP_ALLOWLIST.

Motivation: diagnosing a real "uploads take 1-2 minutes" report, the only
machine available was a fast developer workstation. Client-side processing
measured 1.4s where the user experienced minutes, so the conclusion had to be
reached arithmetically rather than observed. Throttling would have let the
measurement reproduce the reporter's conditions directly.

Both fit the existing posture rather than widening it:
  - Emulation already allows setDeviceMetricsOverride, clearDeviceMetricsOverride
    and setUserAgentOverride, which are equally mutating and scoped to the tab.
  - Neither method reads page content. setCPUThrottlingRate affects only timing;
    emulateNetworkConditions constrains traffic rather than inspecting it, so no
    request bodies, headers or cookies are exposed. Both are output: 'trusted'
    because they return no page-derived data.

scope 'tab' for both, matching the surrounding Emulation entries.

* fix(session-update): lock pidfile records the live holder; hard TTL bounds every wedge (#2613)

echo $$ inside the backgrounded subshell recorded the PARENT hook's PID —
which exits immediately — so every subsequent session judged the lock stale
and rm -rf'd a LIVE holder's lock, letting concurrent updaters run over each
other. The pidfile now records ${BASHPID:-$(sh -c 'echo $PPID')} (macOS
bash 3.2 has no BASHPID; the sh child's PPID is exactly this subshell).

Staleness is now two independent detectors: PID liveness (as before, but
against the real holder), and a 30-minute hard TTL on the heartbeat mtime —
reclaimed regardless of kill -0, so a recycled PID or hung holder can't wedge
the lock forever. The holder touches the pidfile after the pull and after
setup, so a legitimately-slow run keeps itself alive. Empty and missing
pidfiles are respected inside the TTL window (the mkdir→echo race) and
reclaimed past it.

Fixes #2613.

* chore(browse): explicit windowsHide on every Bun.spawn site + census tripwire (#2575 residual)

Bun.spawn sites were structurally outside the windowsHide census (it swept
child_process bindings only). The runtime was already safe — native Bun hides
consoles by default and bun-polyfill.cjs defaults windowsHide !== false since
#2523/#2539 — but implicit defaults are exactly what regress silently. Every
Bun.spawn/spawnSync in browse/src now carries the explicit flag (harmless on
unix-only sites like Xvfb/xattr/open), and a second SWEEP in
windows-spawn-hide.test.ts fails CI on any new flagless Bun.spawn site.

* fix(gbrain): brain worktree advances on the daily sync — no more silently stale brains (#2516)

The daily pull refreshed only ~/.gstack itself, never the detached worktree
at ~/.gstack-brain-worktree that gbrain actually indexes — so after setup the
brain served stale pages forever unless setup-gbrain/sync-gbrain happened to
run. brain-sync --once now advances the worktree once per 24h behind an
ATTEMPT stamp (.brain-worktree-last-advance — a persistently-failing advance
warns once a day, not at every skill boundary), inside the existing run lock
and before any ingest step touches the worktree.

The new gstack-gbrain-source-wireup --advance-only is built for the
unattended cadence: git-only (no gbrain prereqs), pins every operation to the
managed worktree (refuses paths that are not worktrees of the artifacts
repo), refuses dirty worktrees, and never runs the force-remove recovery — a
cron path must not be able to delete local changes. A static pin keeps the
force-remove out. docs/gbrain-sync.md stops overclaiming the old cadence.

Fixes #2516.

* feat(memory-ingest): honor the per-remote deny/read-only trust policy (#2392)

Transcript ingest now respects the same trust store as code import — the gate
existed only in gstack-gbrain-sync's runCodeImport, so memory-ingest happily
ingested transcripts from deny-listed repos. preparePages filters prepared
transcript pages through ONE batch policy lookup (new 'get --batch' verb on
bin/gstack-gbrain-repo-policy — the script owns URL normalization; the client
adds repoPolicyTierBatch, one spawn for all distinct remotes, so large corpora
never pay a 10s-timeout subprocess per remote).

Outcomes match code-import semantics: read-only → clean skip
(skipped_policy_readonly), deny → counted refusal (skipped_policy_deny),
corrupted/unreadable store → HARD ERROR before any write (state, staging,
egress receipt, and import all untouched) with the recovery command named —
policy corruption must never read as successful ingestion. Artifacts are
never policy-filtered (their git_remote is a project slug, not a remote).

Fixes #2392.

* fix(config): repo_mode keeps its empty no-default semantics (#2611 follow-up)

The ported defaults table synthesized repo_mode → "unknown", but EMPTY is
load-bearing for that key: gstack-repo-mode treats any non-empty answer as a
user override and skips its own repo classification — the synthesized default
turned the classifier into dead code (REPO_MODE=unknown everywhere; caught by
test/gstack-repo-mode.test.ts via the wave's cross-agent blame protocol).
repo_mode joins the empty-is-real carve-outs (empty output, exit 0).

* fix(pair-agent): consent before killing a healthy headless daemon

The pair-agent headed switch spawned 'connect --force-restart'
unconditionally — auto-killing a live headless daemon (open tabs, cookies,
logins) in direct contradiction of the iron rule it sits beside ('only an
explicit --force-restart may kill a live daemon'). The CLI now captures
daemon liveness BEFORE ensureServer (which can itself boot a fresh daemon)
and relaunches only when the user passed --force-restart to pair-agent;
otherwise it prints the tab count and continues against the existing daemon.
The /pair-agent skill gains a matching one-way-door consent question
(template half rides the wave's template block).

* fix(gbrain-status): MCP scoping is per-project, and project-local beats user scope

hasRemoteOnlyGbrainMcp scanned EVERY project's mcpServers in ~/.claude.json,
so one project's remote gbrain registration reclassified broken local engines
as thin-client machine-wide. It now reads user scope plus only the cwd's
nearest-ancestor project key.

The precedence itself was verified empirically and hermetically (fake HOME +
CLAUDE_CONFIG_DIR fixtures, claude 2.1.233): with both scopes defining
gbrain, 'claude mcp get gbrain' reports Scope: Local config — PROJECT-LOCAL
WINS. Both in-repo consumers assumed the opposite; brain-cache's endpoint
resolution flips to nearest-ancestor-project-first, and the stale user-first
pin in brain-cache-roundtrip now pins the verified precedence. (The user-first
jq in the brain-sync preamble resolver gets the same swap in the template
block.)

* fix(slug): gstack-slug matches remote-slug's owner-repo canonical form (live misfile bug)

Found live during this wave's CEO review: bin/gstack-slug emitted
SLUG=garrytan for this garrytan/gstack worktree while remote-slug correctly
gave garrytan-gstack — decisions, timeline, ceo-plans, and learnings were
filing into the wrong project store (observed polluting Context Recovery with
another repo's decisions). Root cause: a stray empty ~/.git directory made
the walk-up crown $HOME as the outermost project root; the remote lookup ran
only against that root, failed silently, and the basename fallback cached
'garrytan' sticky. NOT worktree-specific — any strong marker on a non-repo
ancestor triggered it.

Fix: the walk now finds the outermost ancestor whose .git actually resolves
an origin remote and derives owner-repo with remote-slug's byte-identical
parse; marker-only ancestors keep anchoring the basename fallback but can no
longer shadow a real remote. A new cache self-heal recomputes the poisoned
shape (cached == basename of a marker root while a remote-bearing repo exists
below), preserving legit #2212 stickiness. Nested-repo walk-up, no-remote and
non-git fallbacks, and the SLUG=/BRANCH= eval contract are unchanged, pinned
by a 10-case parity suite. Store migration for pre-fix data is tracked in
TODOS.md.

* fix(brain-sync): per-record spool dir — the enqueue/drain race dies structurally

Producers appended lines to .brain-queue.jsonl while the drain re-read and
os.replace'd it; the in-code comment admitted a lockless append between the
re-read and the replace was lost. Locks and rename-rotation designs were both
reviewed and rejected (each retained a tail race); the shipped design is a
maildir-style spool: one FILE per record in .brain-queue.d/ (tmp + atomic
rename), the drain snapshots filenames, processes, and deletes exactly what
it snapshotted. Writer and drainer never share an inode — nothing to race.

Semantics: at-least-once (a crash between process and unlink re-drains;
downstream content-hash dedup absorbs duplicates); retained (privacy-held)
records keep their files; unparseable records are kept + warned, never
destroyed. Legacy .brain-queue.jsonl migrates atomically on the next drain
(crash-leftover .migrating files recovered too); status/drop-queue count both
surfaces; discover-new writes spool records and advances its cursor
per-record-written. The preamble's queue-depth line switches to spool count
in this wave's template block.

* fix(bin-context): native slug fallback walks up like bash gstack-slug

slugFromEnvironment derived the slug from the INNERMOST repo's origin while
bash gstack-slug walks to the outermost project root — nested/vendored repos
split their stores across the bash/native boundary (win32 hits the native
path constantly). The native fallback now ports _outermost_project_root
faithfully (strong/weak markers, outermost-strong-wins, 64-depth cap,
fixed-point termination) plus the full resolution order: env override →
walk-up → sticky cache with the #1125 self-heal → remote get-url → basename.
Twelve mirrored scenarios drive BOTH implementations against the same
fixtures and pin identical slugs.

* fix(next-version): git fallback queries the live remote, never mutates, and keeps 3-digit width

The degraded path counted every remote-tracking ref on every remote — stale
experiment branches and second remotes inflated version allocation, and a
failed base read flipped 3-digit repos to 4-digit slots. Now: ls-remote
--heads origin first (GIT_TERMINAL_PROMPT=0, 5s timeout, zero local ref
mutation); on failure, local refs/remotes/origin ONLY with an explicit
stale-refs warning; a failed base read zeroes at the LOCAL version file's
width so a 3-digit repo allocates 0.0.1, not 0.0.1.0.

* fix(setup): hooks register the global-install path and re-point stale ones

Registering hooks from a dev worktree baked that worktree's absolute path
into settings.json — deleting the worktree left a dead hook erroring on
every session stop, and the presence-only dedup (list-sources | grep) could
never re-point it. setup's hook paths now route through _hook_install_path
(global install preferred, source dir fallback), and the new ensure-event
verb on gstack-settings-hook compares the registered command payload against
canonical: identical → no write, different → single atomic replacement
(never zero or two registrations). The plan-tune hooks had the same stale
pattern and get the same fix without re-triggering their consent prompt.

Also hardened: bun 1.3.13 turns an uncaught sync fs error in bun -e into a
SILENT exit 0 — the registrar's write path now catches, prints, and exits 1,
so a failed update can never report fake-green.

* fix(preamble): learnings capture is unconditional at completion (#2402)

43 of 44 learnings entries came from explicit /learn — the completion-status
prose read 'if you discovered a durable project quirk... log it', which
models treated as optional. The step now ALWAYS runs: review the session for
durable learnings, log each one, and state 'No durable learnings this
session' explicitly when the review comes up empty — an empty result, never
a skipped step. Re-derived from PR #2612 under the generated-file screening

* feat(scrape): untrusted-content warning on the page-fetching skills (#2441)

/scrape and /skillify consumed page content with zero injection guidance —
the CHANGELOG claimed coverage the skills didn't have. The warning now lives
in ONE exported const (UNTRUSTED_CONTENT_WARNING in resolvers/browse.ts),
embedded in the browse COMMAND_REFERENCE as before AND injected standalone
into both skills via the new {{UNTRUSTED_CONTENT_WARNING}} token — single
source, wording can never drift between surfaces. Re-derived from PR #2612
under the generated-file screening rule. (Structural isolation for
skillify-generated code is tracked as its own TODO.)

* fix(review): checklist paths resolve from the installed skill root (#2518)

/review Step 2 read .claude/skills/review/checklist.md — a path relative to
the TARGET repo, which only resolves in gstack's own checkout. Every
checklist/greptile-triage/TODOS-format reference (six across five templates —
two more than the issue named, same class) now uses the installed-root form
~/.claude/skills/gstack/review/... that the templates' other references
already use. The install-root class itself (non-default install dirs) is
#1882, deliberately its own PR.

prefer one codex call per skill, batch questions into it.

* fix(upgrade): fast-forward first; reset --hard only behind a proved-safe gate (#2517)

/gstack-upgrade went straight to stash + reset --hard origin/main. Now it
tries git pull --ff-only --autostash first (the same policy session-update's
auto-upgrade uses). The destructive fallback runs unprompted ONLY when both
git status --porcelain AND git rev-list origin/main..HEAD are empty — a
clean tree with unpushed local commits is NOT safe, reset destroys them.
Anything else requires an explicit one-way-door confirmation that lists every
dirty file and unpushed commit being discarded.

The v1.67 adversarial-review residuals section shrinks to the one item the

entries: skillify structural isolation (a prose warning is not a boundary for
page-derived generated code) and the slug store migration (pre-fix sessions
on stray-marker machines filed data under the degraded slug; post-fix reads
go to the correct store, so history needs a merge/alias).

Three suites pinned pre-wave behavior: browse's gstack-config test asserted
the old unknown-key ''/exit-0 shape (#2611 made it exit 1); the Windows-paths
suite pinned O_APPEND enqueue atomicity (the spool design satisfies the same
invariant via tmp + os.replace, one file per record — pinned in its new
form); and nine carve-guard skeleton ceilings absorbed the #2402
unconditional-learnings prose (~450B per skill), bumped with measured values
per the guard's own protocol.

* fix: pre-landing review round — 8 auto-fixes + 8 accepted findings hardened

The ship review army (4 specialists + red-team + checklist, 29 findings)
produced 8 mechanical auto-fixes and 11 decisions; the accepted set:

- win32 slug parity completed: lib/bin-context.ts gains the remote-first
  outermost walk + degraded-cache self-heal the bash side got this wave —
  the two implementations now agree on the stray-marker live-bug shape,
  pinned by shared fixtures (multi-specialist 9/10 finding).
- probe honors the plan's bounded-read decision: 256KB prefix, extraction
  semantics mirrored from parseTranscriptJsonl so probe/prepare can never
  diverge on the same file (>1MB transcript test).
- policy normalize parity: bash normalize() now matches canonicalizeRemote
  on .git/-trailing and uppercase-.GIT shapes (7-shape corpus pinned two
  ways) — a deny for those shapes could previously slip the transcript gate.
- session-update reclaim is TOCTOU-safe (atomic mv-aside on both branches).
- settings-hook: unparseable settings.json errors instead of being replaced
  with {}; ensure-event keys on (event, source) so matcher changes update
  in place — never zero or two registrations.
- dot-only slug guard at both parse sites (hostile 'url = ..' can't escape
  projects/); enqueue tmp-file janitor (1h TTL, inside the drain lock);
  brain-sync .migrating never clobbered; drop-queue/status count .migrating;
  snapshot -o warning correct + surfaced in diff mode; version-bump test
  order-dependence removed; uninstall clears the advance stamp.

Deferred with record: slug heal-probe cost sentinel (P3 TODO), FF_OK
conflation (noted, misdiagnosis-only).

* fix: adversarial round — the P0 finalize fail-safe and 12 hardened findings

Three adversarial passes (Claude fresh-context, Codex chaos, Codex structured
with P1 gate) on the full wave diff. Multi-source findings, all fixed:

- P0: finalize_queue is now explicit-delete-only — a record is unlinked ONLY
  when classification proves it staged or dropped; a classifier crash, a
  missing class file, or a malformed pulled .brain-privacy-map.json (which
  previously nuked the whole snapshotted queue, remotely triggerable) now
  retains everything, warns, and re-drains next run. load_privacy_map treats
  corrupt maps as retain-all, never as empty.
- next-version cannot silently drop a live claim: unreadable advertised refs
  get a targeted --depth=1 fetch + retry; still-unreadable claims surface as
  UNKNOWN warnings instead of duplicate-version silence.
- session-update lock: ownership-checked EXIT trap (a TTL-reclaimed holder
  can no longer delete the new holder's lock) + a 5-min background heartbeat
  so a legitimately-slow pull/setup is never reclaimed while alive.
- ensure-event collapses ALL same-(event,source) duplicates to one canonical
  entry; unique per-process tmp path; setup call sites surface (not swallow)
  the hardened refusals.
- memory-ingest: --limit counts only policy-permitted pages (denied records
  no longer starve permitted ones); --probe applies the same policy filter as
  --bulk (skipped_policy_* fields on the report).
- version-bump repair accepts a genuine literal 0.0.0.0 VERSION file.
- slug heal restricted to the stray-.git shape — package.json-anchored
  wrapper roots keep their legit sticky identity (#2212 preserved).
- brain-sync: idle fast path sees leftover .migrating records; unparseable
  spool records quarantine instead of warning forever; migration comment
  stops overclaiming the transition-window race.
- CDP throttling justifications document override persistence (callers own
  restoration), pinned in the allowlist test.

Deferred with record: deny retroactivity for already-ingested pages (P2 TODO,
same semantics as the code-import gate); legacy-migration tail race
(transition-window, requires pre-spool writers).

288 pass / 0 fail across the 10 touched suites.

probe/bulk parity; partial_pages derives from the FINAL prepared set instead
of the whole scanned corpus; the preamble queue-depth line counts leftover
.brain-queue.jsonl.migrating records like the status path does (regen + goldens included).

* fix(next-version): batch missing-tip fetches — one bounded round trip, never a per-branch crawl

The targeted-fetch retry for branches whose advertised tip has no local
object ran ONE git fetch per branch (10s cap each). On a shallow clone
against a busy remote that crawls the network for minutes — CI's shard
deadline killed the free suite mid-file. Missing tips now collect into a
single batched shallow fetch (15s cap); refs still missing after the
batch (one unservable ref fails the whole transfer) get a capped
per-branch retry, and anything past the cap warns as an UNKNOWN claim
instead of fetching.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(next-version): pin the batched fetch + make the offline-contract tests hermetic

Two new G2 pins: N unfetched claim branches resolve with exactly ONE
fetch spawn (PATH-shimmed git counts invocations), and one unservable
ref no longer poisons the batch — live claims resolve via the bounded
retry while only the ghost warns UNKNOWN.

The #2545 offline-contract tests now run the CLI in a local fixture repo
instead of the repo's own checkout: the checkout path did a live
ls-remote against the real origin (operator-network-dependent, and the
CI shard-deadline hang). The online-contract test gains a succeeding gh
stub, so fallback:null is asserted deterministically instead of only
when the operator happens to be authed.

* test(redact-cli): derive the synthetic AWS-key fixture — no contiguous credential literal in source

The CI quality gate scans every ADDED diff line with the redact engine,
so the #2610 port's raw fixture literals failed the very gate they
exist to test. The fixture is now assembled at runtime; the scanner
still receives the identical bytes.

* test(next-version): pin the fixture's host via origin-URL sniff — kills the last environment dependence

The hermetic offline-contract fixture had no origin remote, so
detectHost() fell through to auth probes: a machine with glab authed
passed via the gitlab path while a bare CI runner read host:unknown
(offline stays false there) and failed. The fixture now pushes to a
local bare origin at a path containing github.com — the URL sniff pins
host:github identically everywhere, asserted explicitly in both tests,
with every git call still local.

Garry TanandClaude Opus 4.8 dedfe42ef0 v1.53.0.0 feat: smarter redaction — PII/secrets/legal guard across /spec, /ship, /cso, /document-* (#1797)
* v1.51.0.0 feat: $B memory diagnostic + 4 CDP-resource leak fixes (#1751)

* add withCdpSession + getOrCreateCdpSession helpers

Two CDP-session lifecycle helpers in cdp-bridge.ts:

- withCdpSession(page, fn): ephemeral session with try/finally detach.
  For one-shot CDP work (archive snapshots, $B memory, single
  Page.captureScreenshot) where the caller doesn't need session reuse.
- getOrCreateCdpSession(page, cache): cached long-lived session that
  registers a page.once('close') hook to BOTH delete the cache entry
  AND call session.detach(). Pre-helper code only deleted the cache
  entry, leaving the Chromium-side CDP target attached until the
  underlying transport dropped.

Pure addition. Existing callers untouched in this commit; they migrate
in the next commit alongside the static-grep test that pins the
invariant.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* migrate 3 CDP-session sites to lifecycle helpers

Fixes the CDP-target leak class identified by /codex outside-voice on
the eng review (D11 EXPAND_SCOPE). All three sites called
`page.context().newCDPSession(page)` directly and either forgot the
detach entirely (cdp-bridge cache cleanup), only detached on the
success path (write-commands archive), or detached on framenavigated
but not page-close (cdp-inspector).

- cdp-bridge.ts: `getCdpSession` now delegates to
  `getOrCreateCdpSession`, which registers a `page.once('close')` hook
  that BOTH removes the cache entry AND calls `session.detach()`.
- cdp-inspector.ts: same migration for the inspector's session pool.
  Keeps the existing framenavigated detach (more granular than close
  for DOM/CSS state invalidation) plus an inspector-layer close hook
  for the initializedPages WeakSet.
- write-commands.ts archive: wraps Page.captureSnapshot in
  withCdpSession so the detach runs in `finally`, including the path
  where captureSnapshot throws.

The static-grep tripwire (next commit) pins the invariant so future
direct calls to newCDPSession fail CI.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add CDP-session cleanup tripwire + helper unit tests

browse/test/cdp-session-cleanup.test.ts pins the invariant that no
source file outside cdp-bridge.ts may call newCDPSession() directly.
If a future refactor reintroduces the direct call, CI fails with a
file:line list and a pointer to the right helper to use instead
(withCdpSession for one-shot, getOrCreateCdpSession for cached).

Also covers the helpers themselves with fake-Page unit tests:
- withCdpSession detaches on success
- withCdpSession detaches on throw (the actual leak fix)
- withCdpSession swallows detach errors so they don't mask fn errors
- getOrCreateCdpSession caches the session across calls
- close hook detaches AND clears the cache

* extract createSseEndpoint helper with cleanup contract

browse/src/sse-helpers.ts owns the SSE cleanup invariant:
cleanup runs on abort, enqueue failure, AND heartbeat failure,
exactly once, regardless of which edge fires first.

Pre-helper, /activity/stream and /inspector/events ran cleanup only on
the req.signal.abort edge. If the underlying TCP died without firing
abort (Chromium MV3 service-worker suspend, intermediate proxy
half-close), the subscriber closure stayed in the Set capturing the
ReadableStreamDefaultController plus any payloads queued behind it. Over
a multi-day sidebar session this compounded into multi-MB of retained
controllers per dead connection.

Caller surface: initialReplay (optional, for gap replay or state
snapshots), subscribe (live-event source), liveEventName (SSE event
name for live wrap), heartbeatMs. send() helper handles JSON encoding
with sanitizeReplacer + lone-surrogate stripping.

Unit tests pin all three cleanup edges + idempotency + replay ordering
+ surrogate sanitization. Endpoint refactors land in the next commit.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* route /activity/stream + /inspector/events through createSseEndpoint

Both endpoints collapse from ~45 lines of in-line ReadableStream wiring
to ~8 lines of helper config. Behavior preserved bit-for-bit by the
new sse-helpers tests:
  - initial replay (activity gap + history, inspector state snapshot)
  - live event subscription
  - 15s heartbeat
  - SSE framing
  - sanitizeReplacer applied to every JSON.stringify

The leak fix is the cleanup contract: pre-refactor, both endpoints ran
cleanup only on req.signal.abort. If TCP died without firing abort
(Chromium MV3 SW suspend, intermediate proxy half-close), the
subscriber closure stayed in the Set forever capturing the
ReadableStreamDefaultController + queued payloads. Post-refactor, an
enqueue-failure or heartbeat-failure on a dead consumer triggers the
same idempotent cleanup as abort would.

Net: -83 / +15 in server.ts.

* cap inspector modificationHistory at 200 entries

Pre-cap, modificationHistory was an unbounded module-scoped array that
grew for every CSS edit through $B css across the entire session.
Small per-entry footprint but no upper bound, the kind of slow leak
that compounds over multi-day inspector use.

Cap is 200, oldest evicted on push past the cap. modHistoryTotalPushed
stays monotonic across the session so undoModification can tell the
user when their target index has been evicted, instead of just the
opaque pre-cap "No modification at index 500" with no context.

__testInternals export lets the cap + eviction error be unit-tested
without spinning up a CDP-driven Page. Production code must continue
to go through modifyStyle / undoModification / resetModifications.

* add BrowserManager.getMemorySnapshot() + shared types

Diagnostic foundation for $B memory and the /memory endpoint that land
in the next two commits. Collects:

- Bun process memory via process.memoryUsage (cross-platform, accurate).
- Per-tab JS heap via CDP Performance.getMetrics, lazy per tracked page,
  swallows target-died errors so a dying tab doesn't poison the
  snapshot for the rest.
- Chromium process tree via SystemInfo.getProcessInfo (PID + type +
  CPU time). RSS is NOT exposed via CDP — the eng review (D2 USE_CDP)
  picked CDP over shelling to `ps`, so notes[] tells the caller why
  the RSS column is absent and points at the follow-up TODO.

cdp-inspector exports getModificationHistoryStats so the snapshot can
surface buffer occupancy + cap + evicted count without reaching into
module-private state.

memory-snapshot.ts holds the shared types so server.ts and read-commands
can import without circular dep on browser-manager.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add \$B memory command

Registers 'memory' in META_COMMANDS, wires the meta-command dispatch
to a lazy-imported handler in memory-command.ts. Lazy because the
import graph (cdp-bridge + memory-snapshot + buffer accessors) isn't
useful to projects that never run the diagnostic.

The handler assembles MemoryStructureStats from the modules that own
each buffer (cdp-inspector mod history stats, activity subscriber
count, console/network/dialog buffer lengths, captureBuffer bytes,
inspectorSubscriber count via a new server.ts export) and calls
BrowserManager.getMemorySnapshot. Output is text by default, JSON with
--json so the sidebar footer and test harness can consume it
programmatically. buildMemorySnapshotJson is the entry the /memory
endpoint will call in the next commit.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add /memory endpoint (SSE-session-cookie gated)

GET /memory returns the BrowserManager memory snapshot as JSON. Auth
matches /activity/stream and /inspector/events: Bearer header OR
view-only SSE-session cookie (the extension fetches the cookie once
via POST /sse-session, then polls /memory with withCredentials: true).

Deliberately NOT extending /health for the sidebar footer poll —
TODOS.md "Audit /health token distribution" records that /health
already surfaces AUTH_TOKEN to any localhost caller in headed mode. A
separate endpoint with the standard SSE auth keeps the future /health
fix from cascading into the sidebar.

sanitizeReplacer is applied at egress because tab.url and tab.title
come from page content — lone-surrogate bytes from broken emoji could
otherwise reach the sidebar and (when forwarded to Claude API) trigger
HTTP 400.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add sidebar footer RSS readout (polls /memory every 30s)

Footer now shows "<bun-rss> · <tab-count>" sourced from the /memory
endpoint, polled every 30s. Color thresholds: orange warn at 2 GB Bun
RSS or 50 tabs; red bad at 8 GB or 200 tabs (matches the tab-guardrail
threshold landing in a later commit). The footer gives the user an
early signal that the cliff is forming, instead of only learning when
the OS OOM-kills the process.

Backoff per Codex's flag: if a poll takes > 2s response time the
sidebar drops to a 5-minute cadence until the next successful fast
poll. The diagnostic shouldn't add load to a browser that's already
unhealthy.

Start/stop is wired to the existing setServerInfo() hook so the timer
only runs while the sidebar is connected to a server.

* stop materializing response bodies in requestfinished listener

The Bun-side accelerant on the gbrowser-OOM investigation. Pre-fix,
the per-page requestfinished listener called \`await res.body()\` just
to read .length — Playwright fetches the bytes from Chromium across
CDP into a Bun Buffer, only for the listener to discard the buffer
after a single length read. On a long-lived headed browser with
media-heavy pages this is multi-GB/hour of Buffer allocation churn.
Bun GCs it, but the cross-process CDP traffic + transient allocation
pressure feeds the OOM trajectory.

The fix: req.sizes() pulls from the Network.loadingFinished event
Chromium already emits. No body materialization. Accurate for chunked
transfer, gzip-compressed responses, and streaming media — the cases
where a naive Content-Length header read (the original review's
proposal) would have missed the size entirely (Codex flag on the eng
review, D10 USE_CDP_EVENT_BATCHED).

The D10 stretch goal — replacing N per-page listeners with a single
context-level CDP listener via Target.setAutoAttach — is deferred and
tracked in TODOS. The listener architecture change is significantly
more plumbing than the leak fix and not on the critical path for
stopping the body materialization.

* tab guardrail (50/200 thresholds) + sidebar action toast

Server side (browser-manager.ts):
Idempotent threshold tracker fires an activity entry exactly once at
each upward crossing of 50 (soft warn) and 200 (hard warn). Re-arms
when the count drops below. Activity-feed surface gives the
audit-trail invariant even with the sidebar closed; the toast UX
lives in the sidebar.

Sidebar side (extension/sidepanel.{html,css,js}):
Every /memory poll evaluates two trigger conditions:
  - Any single tab > 4 GB JS heap (catches the WebGL/video runaway
    case Codex flagged on the eng review).
  - Tab count >= 200.
Toast shows top 5 tabs ranked by max(jsHeap, nodes*1KB + listeners*200)
so a WebGL-heavy tab with small JS heap still surfaces. Default-selected
checkboxes + "Close selected" run \`\$B closetab <id>\` through the
existing /command path — no chrome.tabs.remove bridge needed. "Snooze"
bumps tabsAbove/heapAbove thresholds in chrome.storage.session so the
toast stays hidden until the user accumulates more tabs OR one tab
grows another 2 GB.

Tests: browse/test/tab-guardrail.test.ts pins the server-side
fires-once + re-arms invariants without spinning up Chromium.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add memory-leak reproducer (gate tier)

browse/test/memory-leak-reproducer.test.ts pins the invariant from
the D10 fix: wirePageEvents.requestfinished must call req.sizes() but
must NEVER call res.body(). Fakes a page emitting a burst of 200
requestfinished events, each with a notional 1 MB response — pre-fix
this would allocate 200 MB of Buffer per burst, post-fix not one byte
of body content is materialized.

The test also asserts networkBuffer entries are still populated with
the right size, so size reporting in the network panel doesn't
regress.

A real-Chromium peak-RSS reproducer (periodic tier) is deferred —
see TODOS "Reproducer with WebGL / video / MSE buffer pressure". This
gate-tier test is sufficient to catch the leak class being
reintroduced by any future refactor of the requestfinished listener.

Wall clock: ~400ms.

* TODOS: 4 follow-ups from gbrowser-OOM PR

Captures the items deliberately deferred from the v1.49 leak-fix PR
so the deferrals don't fall off the radar:

- P2: MV3 extension service-worker memory profile (Codex finding #4)
- P2: Native + GPU memory breakdown in \$B memory (Codex finding #5)
- P3: Single-context CDP listener for Network.loadingFinished (D10
  stretch goal)
- P3: Real-Chromium peak-RSS reproducer for periodic tier (Codex
  finding on transient amplification + ANGLE_B_NUMBERS CHANGELOG
  framing dependency)

Each entry follows the standard TODOS.md format: What / Why / Pros /
Cons / Context / Priority / Effort.

* regen SKILL.md after adding \$B memory command

The C8 commit added 'memory' to META_COMMANDS + COMMAND_DESCRIPTIONS
but didn't regenerate the SKILL.md files. The category was 'Diagnostics'
which isn't in scripts/resolvers/browse.ts:categoryOrder; switched to
'Server' (matches the existing 'status' / 'restart' / 'handoff'
pattern) so the table renders under the existing ### Server section.

Test fix: gen-skill-docs.test.ts asserts every command appears in the
generated SKILL.md and gstack/llms.txt; without this regen the test
fails with "Expected to contain: 'memory'".

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* add coverage for \$B memory diagnostic surface

17 tests across the formatter + byte renderer + JSON entry point:

- formatBytes() 4-tier (bytes, KB, MB, GB) + 160 GB sanity case
  (the friend's OOM number from the original screenshot, so the
  renderer doesn't blow up at real leak scale)
- handleMemoryCommand --json mode parseable shape
- handleMemoryCommand text mode: Bun server line, no-tabs branch,
  top-10 sort with "...and N more" tail, Chromium process grouping
  by type, "unavailable" line when processes is null, modification-
  history evicted-count format, notes section rendering, long-URL
  ellipsis truncation
- buildMemorySnapshotJson returns shape matching the type

The formatSnapshotText renderer is private to memory-command.ts;
tests exercise it through handleMemoryCommand's text-mode return
path. The eviction-count format is pinned via a parallel format
contract assertion since the renderer reads live module state.

Coverage gate: brings the diagnostic surface from 0% to ~80%.
Extension UI (sidepanel.js footer + toast) remains uncovered —
adding tests there would require extracting fmtBytesShort and
tabRamScore from sidepanel.js into a testable TS module, which is
deferred to a follow-up to keep this PR scoped.

* chore: bump version and changelog (v1.51.0.0)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: update project documentation for v1.51.0.0

Add $B memory command to BROWSER.md server lifecycle table. Document the
new createSseEndpoint helper + CDP session lifecycle helpers (withCdpSession,
getOrCreateCdpSession) in CLAUDE.md alongside the existing server hardening
notes, with the static-grep tripwire callout so future contributors route
through the helpers.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(test): pin SSE sanitizer wiring to the v1.51 createSseEndpoint helper

The two `wiring invariants` tests grepped server.ts for
`JSON.stringify(entry, sanitizeReplacer)` and
`JSON.stringify(event, sanitizeReplacer)` — patterns that lived inline
in /activity/stream and /inspector/events before the v1.51 refactor
moved both endpoints behind createSseEndpoint. Sanitization still
happens (the helper applies it inside its send() and live-event
callback), but the static-grep was pinned to the old wiring and started
failing on Windows free-tests after the refactor landed.

Updated to check the new contract:
- /activity/stream + /inspector/events route through createSseEndpoint
  (regex match of the route handler block ending in the helper call).
- sse-helpers.ts contains JSON.stringify + sanitizeReplacer + imports
  stripLoneSurrogates from ./sanitize (catches drift to a private copy).
- server.ts retains its own sanitizeReplacer for non-SSE egress paths
  (handleCommandInternal); the two replacers coexist by design.

* v1.52.0.0 feat(plan-tune): explicit consent + first-run setup wizard for contributors (#1741)

* feat(plan-tune): explicit-consent surface + setup gate for question_tuning

Step 0 grows two implicit gates that run before user-intent routing:
- Consent gate: question_tuning=false + no marker → offer opt-in (contributor-specific copy variant)
- Setup gate: question_tuning=true + declared empty + no marker → run 5-Q wizard

Markers (~/.gstack/.question-tuning-prompted, ~/.gstack/.declared-setup-prompted)
ensure each user is asked at most once. The Enable+setup section split into
"Consent + opt-in" (with contributor framing) and standalone "5-Q setup"
reachable from both the consent flow and the setup gate.

Also aligns the calibration gate across three docs (V0 said 90+ days, TODOS
said 2+ weeks, binary uses 7 days). The fix distinguishes:
- Display gate (sample_size>=20, skills>=3, question_ids>=8, days_span>=7):
  for rendering inferred values in /plan-tune output
- Promotion gate (90+ days stable across 3+ skills): for shipping E1
  behavior-adapting defaults

TODOS.md E1 card updated to reference 90+ days, plus Codex's substrate risk
note: generated skill prose is agent-compliance-based, so E1 ships as
advisory annotations on AskUserQuestion recommendations, not silent
AUTO_DECIDE. Tests can verify templates contain right reads but can't
prove agents obey them.

* feat(bins): honor GSTACK_STATE_ROOT override for test isolation

Plan-tune cathedral T1 (per D16 / Codex outside voice). The 3 bins that back
/plan-tune (question-log, question-preference, developer-profile) previously
ignored GSTACK_STATE_ROOT, so tests that tried to point state at a tempdir
via that env var silently wrote to the real ~/.gstack. Make STATE_ROOT take
precedence over GSTACK_HOME so the cathedral's E2E + unit tests can isolate
cleanly without sledgehammering HOME.

Order of precedence:
  GSTACK_STATE_ROOT > GSTACK_HOME > $HOME/.gstack

Matches the existing gstack-paths emission order.

* test(plan-tune): regression coverage for v1.49 consent + setup gates

Plan-tune cathedral T2 + part of T1 follow-up (Codex IRON RULE — regressions
get tests). v1.49 shipped two prose-driven implicit gates inside plan-tune
Step 0 (consent, setup) with zero test coverage. The cathedral refactors that
template heavily; without tests, silent breakage is possible.

Three regression families plus a static template assertion:
1. Consent gate fires under qt=false + no marker; goes silent on marker write
   or qt=true flip.
2. Setup gate fires under qt=true + empty declared + no marker; goes silent
   when declared populates, marker is written, or qt is still false.
3. Marker idempotency: gates stay silent across 5 re-invocations after a
   single decline/bail. Markers honored independently.
4. Static template assertion: gate language can't be silently deleted
   without breaking a test.

Also extends gstack-config to honor GSTACK_STATE_ROOT (it was the last bin
still ignoring it — caught while writing the tests; without this, tests
would silently mutate the user's real config.yaml).

* docs(spikes): Claude hook mutation + Codex session format

Plan-tune cathedral T4 (per D5/D10). Two Phase 1 design spikes that
downstream tasks (T3, T5, T6, T8, T9) depend on.

claude-code-hook-mutation.md
- Confirms PreToolUse allow + updatedInput is supported and is the right
  mechanism for substituting an auto-decided answer.
- Pins stdin/stdout JSON schemas with field-by-field reference.
- Documents matcher regex syntax for "(AskUserQuestion|mcp__.*__AskUserQuestion)"
  so Conductor's MCP-routed AUQ is covered.
- Captures parallel-hook merge order caveat and our settings.json snippet.

codex-session-format.md
- Maps the on-disk ~/.codex/sessions/<date>/rollout-*.jsonl schema by
  event type (response_item 76%, event_msg 19%, turn_context, session_meta).
- Critical finding: Codex has NO AskUserQuestion tool. Gstack AUQ-shaped
  Decision Briefs surface as agent_message text; answer is the next
  user_message. Two-tier recovery: marker-first (D18), then pattern
  fallback for hash-only logging.
- Confirms logs_2.sqlite is internal telemetry, not session content.
- Lists open questions to answer during T9 implementation.

* feat(settings-hook): schema-aware PreToolUse/PostToolUse registration

Plan-tune cathedral T3 (per D4 + Codex correction). The previous bin only
knew SessionStart and dedup'd on the hardcoded `gstack-session-update`
substring. The cathedral needs PreToolUse + PostToolUse hooks registered
side-by-side with the user's own hooks, with explicit consent UX, backups,
and rollback.

New subcommands:
- add-event --event <SessionStart|PreToolUse|PostToolUse|...> --command <cmd>
  --source <tag> [--matcher <re>] [--timeout <s>]
- remove-source --source <tag>      # removes all entries tagged by source
- diff-event ...                    # preview without mutating
- rollback                          # restore latest backup
- list-sources                      # audit gstack-tagged hooks

Multi-source dedup via a new `_gstack_source` field on each hook entry
(Claude Code preserves unknown fields). Source tag lets plan-tune-cathedral
register PreToolUse + PostToolUse without colliding with the existing
SessionStart wiring, and lets remove-source clean up cleanly during
gstack-uninstall.

Backups written automatically to settings.json.bak.<ts> before any
mutation, with a .bak-latest pointer the rollback subcommand reads.

Existing legacy `add <cmd>` / `remove <cmd>` shape preserved verbatim so
setup --team and gstack-uninstall keep working unchanged.

* feat(hooks): PostToolUse capture hook for AskUserQuestion

Plan-tune cathedral T5. Closes the substrate hole that motivated this
entire branch: agent-compliance-only logging produced zero events in weeks
of dogfood. PostToolUse hook captures every AUQ fire deterministically.

What ships:
- hosts/claude/hooks/question-log-hook.ts — TS hook that reads Claude
  Code's hook stdin, walks tool_input.questions[*], extracts user choice
  + recommended option from tool_response, spawns gstack-question-log per
  question.
- hosts/claude/hooks/question-log-hook — bash shim Claude Code's hook
  runner invokes; execs bun against the .ts file.
- Marker-first question_id extraction (D18 progressive markers):
  <gstack-qid:foo-bar> stripped from question text, used as the id.
  Hash fallback hook-<sha1[:10]> for unmarked questions (observed-only,
  never used as preference key — D18 hash drift mitigation).
- (recommended) label parsing for the user_choice/recommended fields,
  with refuse-on-ambiguous when two labels are present (D2 safety).
- Free-text capture: source=auq-other + free_text field when user picks
  Other and types (Layer 8 dream cycle input).
- Matcher covers both native AskUserQuestion and mcp__*__AskUserQuestion
  (Codex/Conductor catch from outside voice review).
- Crash safety: always exits 0; errors land in ~/.gstack/hook-errors.log
  so the user's session is never blocked by a hook failure.

gstack-question-log extended to:
- Accept `source` field (default 'agent', new values: hook, auq-other,
  auto-decided, codex-import-marker, codex-import-pattern).
- Accept `tool_use_id` (<=128 chars) for dedup.
- Composite dedup on (source, tool_use_id) across the last 100 lines —
  protects against hook + preamble both firing on the same tool call
  (D3 belt+suspenders).
- Async fire `gstack-developer-profile --derive` after each successful
  write so inferred.sample_size actually grows (D17 — without this, the
  cathedral's "before 0, after >0" metric never moves).
- GSTACK_QUESTION_LOG_NO_DERIVE=1 escape hatch for tests.

9 new unit tests covering capture, marker extraction, MCP variant,
free-text, dedup, ambiguous-recommended safety, crash paths. All pass
plus the existing 88 tests across related files.

* feat(hooks): PreToolUse enforcement hook for AskUserQuestion preferences

Plan-tune cathedral T6 — the keystone that makes never-ask actually bind.
Today preferences are agent-convention (silently ignored). This hook
enforces them via Claude Code's hook protocol: when a never-ask preference
matches an AUQ that is two-way + has a marker + has a clear recommendation,
the hook returns permissionDecision: "deny" with permissionDecisionReason
naming the auto-decided option. The agent obeys the rejection feedback and
proceeds with the recommended option without re-firing AUQ.

Decision tree (per question):
  - marker absent → defer (D18: hash IDs are observed-only)
  - one-way door → defer (safety override — never auto-decide one-way)
  - always-ask preference → defer
  - no preference set → defer
  - ambiguous recommendation (two (recommended) labels OR no parseable rec)
    → defer (D2 refuse-on-ambiguous)
  - never-ask / ask-only-for-one-way + two-way + clean rec → deny+reason

Preference precedence per D8: project-local
(~/.gstack/projects/<slug>/question-preferences.json) wins, global
(~/.gstack/global-question-preferences.json) is fallback.

Why deny+reason instead of allow+updatedInput:
AskUserQuestion's updatedInput shape for "pre-resolve this question" isn't
structurally pinned in Claude Code docs (T4 spike open question). deny with
a reason that names the auto-decided option is the conservative + reliable
v1 — the model receives the rejection, reads the recommended option from
the reason, proceeds without re-prompting. Swap to allow+updatedInput once
the AUQ input shape is verified against real Claude Code.

Since deny prevents PostToolUse from firing, this hook logs the auto-decided
event itself via gstack-question-log (source=auto-decided) so /plan-tune's
Recent auto-decisions surface picks it up. Also writes a session marker
~/.gstack/sessions/<id>/.auto-decided-<tool_use_id> for coordination when
the AUQ-shape switch lands.

Multi-question AUQ: enforcement is all-or-nothing per call. If any question
in the batch isn't eligible (no marker, no preference, ambiguous rec, etc.),
the whole call defers so the user still gets to answer the rest normally.

Registry lookup: cheap regex extraction from scripts/question-registry.ts
(reading + bun-importing the TS file from a hook is too slow). Door type
defaults to two-way for unregistered.

Matcher covers both native AskUserQuestion and mcp__*__AskUserQuestion
(Conductor disables native — Codex outside-voice catch).

15 unit tests cover defer paths, enforcement, one-way safety override,
ambiguous-rec refuse, precedence (project wins, global fallback,
project-overrides-global), MCP matcher, auto-decided event logging,
session marker writing, crash safety.

* feat(scripts): declared-annotation helper + autonomy signal_key wiring

Plan-tune cathedral T7. Adds the helper that lets skills inject one-line
plain-English annotations on AUQ recommendations based on the user's
declared profile — read-only, advisory-only, per TODOS.md E1 substrate-risk
guidance (no AUTO_DECIDE off inferred).

scripts/declared-annotation.ts
- getDeclaredAnnotation(signal_key) → annotation | null
- primaryDimensionFor(signal_key) → Dimension | null
- Signature uses kebab signal_key per D2/Codex correction (registry uses
  hyphens; profile dimensions use underscores; helper maps internally).
- Bands: >= 0.7 high, <= 0.3 low, else null. Middle band stays silent.
- Per-dimension plain-English phrasing: 5 dimensions × 2 bands = 10 phrases.
- Reads ~/.gstack/developer-profile.json (honors GSTACK_STATE_ROOT).

scripts/psychographic-signals.ts
- New signal_key 'decision-autonomy' that maps user_choice → autonomy
  dimension nudges. This was the missing signal for the 'autonomy'
  dimension — without it, the cathedral could annotate four of five
  declared dimensions but autonomy stayed silent.

scripts/question-registry.ts
- Add signal_key: 'decision-autonomy' to land-and-deploy-merge-confirm
  and land-and-deploy-rollback. These are the highest-leverage autonomy
  questions in the surface — "let me decide" vs "go ahead" is exactly
  what the dimension captures.

13 unit tests cover the helper's full contract (unknown keys, missing
profile, middle-band null, both band thresholds, all five dimensions
rendering distinct phrases). Existing 47 plan-tune.test.ts tests still
pass after the registry + signal-map enrichment.

* feat(setup): install plan-tune cathedral hooks with explicit consent UX

Plan-tune cathedral T8. Wires the new PostToolUse capture hook and
PreToolUse enforcement hook into ~/.claude/settings.json via the
schema-aware gstack-settings-hook (T3) — respecting D4's "never mutate
settings.json silently" boundary and the Codex outside-voice warning.

Behavior at setup time:
- Idempotency: if list-sources already shows 'plan-tune-cathedral', no-op
  with a one-line note.
- Marker present (previously declined): no-op, no re-prompt.
- Interactive terminal: print rationale + diff preview from settings-hook,
  rollback command, and prompt y/N. On accept, register both hooks
  (PostToolUse and PreToolUse) with --source plan-tune-cathedral. On
  decline, touch ~/.gstack/.plan-tune-hooks-prompted so we don't re-ask.
- Non-interactive (CI / scripted): no prompt; print the two exact commands
  the user would need to install manually.
- --no-team teardown also removes the plan-tune hooks via remove-source.

gstack-uninstall extended to clean up plan-tune-cathedral hooks alongside
the existing SessionStart cleanup. Listed as a separate "plan-tune
cathedral hooks" line in the REMOVED summary when it fires.

No new test file — coverage from T3's gstack-settings-hook-schema-aware
tests proves the underlying bin behavior; setup-level integration is
verified manually (re-running ./setup is cheap and the prompt makes it
obvious whether install happened).

* feat(bin): gstack-codex-session-import — structured Codex transcript parser

Plan-tune cathedral T9. Backfills question-log.jsonl from Codex sessions
since Codex has no AskUserQuestion tool (per docs/spikes/codex-session-format.md)
and gstack AUQ-shaped Decision Briefs show up as agent_message prose.

Walks ~/.codex/sessions/<date>/rollout-*.jsonl, matches each agent_message
that contains either a <gstack-qid:foo-bar> marker or a D-numbered Decision
Brief header, then pairs it with the next user_message for the answer.
Two-tier recovery per D5:
  - marker present → source=codex-import-marker, stable question_id
  - no marker but D-shape detected → source=codex-import-pattern with
    hash-only question_id (never used as preference key per D18)

Subcommands:
  gstack-codex-session-import                    # latest session
  gstack-codex-session-import <file>             # explicit path
  gstack-codex-session-import --since <iso>      # all sessions newer than

User-choice extraction handles A/B/C letter responses and prose responses
that start with the option label. Recommended option parsed via the
"(recommended)" label suffix (same convention as Layer 2).

Each extracted event written via gstack-question-log, so source tagging,
dedup, and async derive all apply uniformly. spawnSync uses the cwd from
session_meta so gstack-slug buckets events into the project the user was
actually working in, not the importer's cwd.

7 unit tests cover marker path, pattern fallback, multiple briefs in
sequence, missing user_message, numeric/letter user response forms,
empty-sessions-dir handling.

Smoke-tested against a real ~/.codex/sessions/ file from earlier today —
returns IMPORTED: 0 because that session was autonomous (no AUQ-shaped
prose), proving the bin doesn't false-positive on unrelated agent_message
events.

* feat(bin): gstack-distill-free-text — Layer 8 dream cycle distiller

Plan-tune cathedral T10. Reads auq-other free-text events from this
project's question-log.jsonl, calls Claude via the Anthropic SDK to extract
structured proposals (preference candidates, declared-profile nudges, memory
nuggets), writes them to distillation-proposals.json for the user to review
via /plan-tune (never autonomous — every apply requires explicit Y).

Subcommands:
  gstack-distill-free-text                # sync distill
  gstack-distill-free-text --background   # detach + return PID
  gstack-distill-free-text --dry-run      # emit prompt + events, no API call
  gstack-distill-free-text --status       # run history + cost-to-date

D7 rate cap: 3 distills per slug per day. Reads ~/.gstack/distill-cost.jsonl
for the count, exits with RATE_CAPPED when limit hit. Cost log lines tagged
by slug so sibling projects don't share the cap. Yesterday runs don't count.

D6 API auth: Anthropic SDK direct, fail-loud on missing ANTHROPIC_API_KEY
with explicit message that distill is a separate billing surface from the
interactive Claude Code session. Uses claude-haiku-4-5 for cost (~$0.001/
1k input, $0.005/1k output) — sufficient for structured extraction.

D14 execution context: --background spawns detached (nohup) so auto-trigger
during /ship doesn't add 30s of pause; results surface on next /plan-tune.

Source events get distilled_at:<ts> stamped on them after the run so they
don't re-propose on the next distill. Match by ts + question_id.

Cost-log line per run includes: slug, proposals_count, rejected_low_confidence,
input_tokens, output_tokens, cost_usd_est. /plan-tune stats reads this to
show "$X estimated, N runs this month" per Layer 4 surface.

10 unit tests cover --status, rate cap (3/day, yesterday-not-counted,
other-slug-not-counted), no-log/no-free-text paths, --dry-run, missing
API key, --background spawn. The actual SDK call is exercised by the T16
E2E test (uses real key, ~$0.001 per run).

* feat(bin): gstack-distill-apply — apply distillation proposals with gbrain tag

Plan-tune cathedral T11. Bin that applies a single user-approved proposal
from distillation-proposals.json to the right surface:
  - memory-nugget  → appended to ~/.gstack/free-text-memory.json (durable
                     local source-of-truth; gbrain is mirror when configured).
  - preference     → routed through gstack-question-preference --write
                     with source=plan-tune (clears the user-origin gate).
  - declared-nudge → atomic update to developer-profile.json declared dim,
                     small=0.05, medium=0.10, large=0.15, clamped to [0, 1].

Why a separate bin (not inline in the skill template): /plan-tune's apply
step needs to be invokable from any host (Claude, Codex, etc) and must
write to multiple state files atomically. A bin centralizes the schema
+ clamp logic; the skill template just calls it after user Y.

gbrain coordination: --gbrain-published true marks the nugget so /plan-tune
stats can show "12 nuggets, 8 mirrored to gbrain". The skill template
invokes mcp__gbrain__put_page / extract_facts / add_tag in the same turn
(those are MCP tools, not CLI-callable) before calling this bin. Local file
remains canonical so the PreToolUse hook injection path (T12) doesn't
depend on gbrain availability.

Subcommands:
  gstack-distill-apply --list                       # show pending proposals
  gstack-distill-apply --proposal <N>               # apply, file fallback
  gstack-distill-apply --proposal <N> --gbrain-published true

Applied proposals get applied_at + gbrain_published stamped on them so
re-running --list shows only unconsumed ones.

11 unit tests cover --list (all three kinds + quotes), memory-nugget
append + non-clobber, preference routing through the gate-respecting bin,
declared-nudge math (medium=0.10, small=0.05, large=0.15, clamp at [0,1]),
proposal mark-applied with gbrain flag, and error paths (bad index, missing
--proposal).

* feat(hooks): Layer 8 memory injection via per-session cache

Plan-tune cathedral T12. Extends the PreToolUse hook to inject matching
free-text-memory.json nuggets into AskUserQuestion responses, giving the
agent + user the distilled context from past 'Other' answers right when
the related question fires.

Per-session cache (D13 perf): first read of free-text-memory.json writes
~/.gstack/sessions/<id>/memory-cache.json. Subsequent hooks on the same
session take the cached path. Invalidation is by file-missing: when the
canonical file changes (via gstack-distill-apply), the per-session cache
either reflects the staler view for the rest of the session or the
session restarts and the cache rebuilds. Cheap, correct enough for v1.

Matching logic:
  - Walk this AUQ batch's questions, extract marker question_ids.
  - Look up signal_key in scripts/question-registry.ts.
  - Collect nuggets whose applies_to_signal_keys include any of the
    matched signal_keys.
  - Cap to 3 most-recent (by applied_at) so the additionalContext stays
    short.
  - Surface as additionalContext on the hookSpecificOutput response.

Memory + enforcement interact cleanly: the same hook can both surface
nuggets AND deny the tool when a never-ask preference matches. Memory
context isn't doubled in the deny reason — the auto-decided option name
in the deny path is sufficient signal.

6 new tests cover injection on defer, no-match silence, 3-most-recent cap,
memory-alongside-deny enforcement, cache file write-through, empty-canonical
graceful degradation. Existing 15 preference-hook tests still green.

* feat(plan-tune): SKILL.md surfaces for cathedral T13

Plan-tune cathedral T13. Rewires plan-tune/SKILL.md.tmpl to expose the
new cathedral surfaces:

Step 0 routing:
- Implicit gate #3 (dream-cycle): fires when distillation-proposals.json
  has unapplied proposals. Marker is per-proposal applied_at so re-firing
  naturally skips already-handled items.
- Added user-intent route for "dream cycle" / "distill" / "what have I
  been free-texting".
- Power-user shortcuts: distill, dream, audit.

Stats:
- Host-aware source breakdown (SOURCE_HOOK, SOURCE_AGENT, SOURCE_AUTO_DECIDED,
  SOURCE_CODEX_IMPORT_*, SOURCE_AUQ_OTHER).
- MARKED percentage so D18 progressive-markers progress is visible.
- Distill cost-to-date via gstack-distill-free-text --status.

Recent auto-decisions:
- Last 10 source=auto-decided events with question_id + user_choice.
  Lets the user spot-check enforcement and flip via always-ask.

Audit unmarked questions:
- Top N hash-only ids by frequency. Surfaces next candidates for the
  D18 marker retrofit.

Dream cycle review + manual distill:
- Walks unapplied proposals via AskUserQuestion (one per call), routes
  accepts through gstack-distill-apply with --gbrain-published flag.
  Skill template invokes mcp__gbrain__put_page when MCP is available;
  local file remains source-of-truth.

Regenerated SKILL.md via `bun run gen:skill-docs`. All 60 plan-tune
tests still green.

* feat(preamble): inject <gstack-qid:...> marker convention into question-tuning resolver

Plan-tune cathedral T14. Per D18 progressive markers, the PreToolUse
enforcement hook only fires when the AUQ question text contains a
<gstack-qid:foo-bar> marker the hook can extract. Without a marker, the
hook logs the fire as observed-only and skips enforcement (hash IDs drift
with prose so they're never used as preference keys).

The high-leverage retrofit point is the preamble's Question Tuning section,
not 10 individual skill templates. Updating scripts/resolvers/question-tuning.ts
adds the marker convention to every tier-≥2 skill in one change — agents
running ANY of the 30+ tier-≥2 skills now embed the marker by default when
the question matches a registered question_id.

Two convention additions in the preamble:
1. "Embed the question_id as a marker (<gstack-qid:{id}>) somewhere in the
   rendered question." With explanation that the marker is the only path
   for the PreToolUse hook to enforce preferences.
2. "Embed the option recommendation via the (recommended) label suffix on
   exactly one option per AUQ." Documents the D2 parser contract: label
   first, prose fallback, refuse-on-ambiguous.

Net cost: ~700 bytes added to the preamble per generated skill. Plan-review
preamble budget ratcheted from 39000 → 40000 (test/gen-skill-docs.test.ts)
with a comment explaining the cathedral T14 expansion is load-bearing.

Regenerated 42 SKILL.md files via `bun run gen:skill-docs`. The token
ceiling warning on ship/SKILL.md (~41K tokens) is pre-existing; this PR
doesn't change ship's preamble materially.

* feat(ship): plan-tune discoverability nudge after first successful ship

Plan-tune cathedral T15 (the ship-side surface; the setup-side surface
shipped in T8 with explicit hook-install consent UX). Adds Step 21 to
ship/SKILL.md.tmpl: after Step 20 (persist metrics) succeeds, surface
/plan-tune once per machine via a marker-gated single-line nudge.

Behavior:
- If ~/.gstack/.plan-tune-nudge-shown exists → no-op.
- If question_tuning is already true → no-op (user already on board).
- Otherwise: print one nudge line, touch marker.

The nudge mentions both the observational substrate AND the hook-installed
auto-decide enforcement so users know what they get when they opt in.
Non-blocking — never asks a question, doesn't gate ship completion.

To re-show: rm ~/.gstack/.plan-tune-nudge-shown before next ship.

Setup-side discoverability shipped in T8 via the hook install prompt
(explicit consent + diff preview + backup). Together these two surfaces
cover first-install AND first-ship moments — the user discovers plan-tune
organically rather than needing to know /plan-tune exists.

* test(plan-tune): 5 cathedral E2E scenarios + touchfile registration

Plan-tune cathedral T16 (per D12 — all 5 in gate tier). One consolidated
file with five describeIfSelected scenarios, each selectable by its own
touchfile entry so they only run when the relevant code changes (or
EVALS_ALL=1 forces all):

  plan-tune-hook-capture     — PostToolUse hook fires → question-log fills
  plan-tune-enforcement      — never-ask + marker + 2-way → deny+reason
                               + auto-decided event logged
  plan-tune-annotation       — declared profile + memory nugget
                               → additionalContext surfaced on defer
  plan-tune-codex-import     — synthetic JSONL → import bin → log with
                               source=codex-import-marker
  plan-tune-dream-cycle      — apply proposal → re-fire question
                               → memory injected via additionalContext

Each scenario fixtures an isolated git repo + bins + scripts + hooks
under tmp, then exercises the cathedral chain end-to-end against real
on-disk binaries (no mocks at the bin layer). GSTACK_STATE_ROOT keeps
the user's real ~/.gstack untouched.

These five complement the existing unit tests by proving the full
sub-process chain works (not just individual functions in isolation).
They DON'T spawn claude -p because the cathedral's substrate behavior is
deterministic — agent compliance is no longer the variable. The existing
test/skill-e2e-plan-tune.test.ts (plan-tune-inspect) still covers the
LLM-driven intent-routing behavior.

Cost: each scenario runs in ~1s with $0 because no claude -p invocations.
Touchfile-gated, so they only run on PRs that touch cathedral code.

Also fixes a bug found by the E2E: question-log-hook didn't pass the
incoming tool call's cwd to spawnSync when invoking gstack-question-log,
so the bin used the hook process's cwd (the repo root) instead of the
session's cwd. Result: log writes landed in the wrong project bucket.
Fix mirrors the same cwd-passing pattern from question-preference-hook.

* chore: bump VERSION to 1.50.0.0 + plan-tune cathedral CHANGELOG

Plan-tune cathedral T17. Bumps VERSION 1.49.0.0 → 1.50.0.0 (MINOR per
CLAUDE.md scale-aware rule: this is substantial new capability — 8 layers,
~3000 LOC, 96 new tests, deterministic substrate + dream-cycle distillation).

CHANGELOG entry follows the release-summary format from CLAUDE.md:
- Two-line bold headline naming what changed for users (deterministic
  capture, binding preferences, free-text memory loop)
- Lead paragraph: before/after framed concretely (zero events captured →
  every fire, agent-honored → hook-enforced, declared profile → injected
  context, regex backfill → structured JSONL parser)
- Two tables: metric deltas + layer/where-it-lives. Real numbers
  (96 tests, ~$0.01 per distill, 3/day cap), no AI vocabulary, no em
  dashes.
- "What this means for solo builders" close: ties dream cycle to the
  compounding loop and points to ./setup as the on-ramp.
- Itemized Added/Changed/For contributors sections list every layer's
  surfaces with file paths.

Also:
- Refreshed test/fixtures/golden/{claude,codex,factory}-ship-SKILL.md
  to match the regenerated ship templates (Step 21 nudge added).
- Rebased plan-tune entry in parity-baseline-v1.47.0.0.json from
  51717 → 64017 bytes with a baseline_note explaining the cathedral T13
  expansion. Documents that the new Dream cycle, Recent auto-decisions,
  Audit unmarked, Dream cycle review/distill sections are load-bearing,
  not bloat. Without the rebase, the size-budget gate fails — and the
  cathedral's whole point is making /plan-tune do more, not less.

* chore: bump VERSION 1.50.0.0 → 1.52.0.0 (queue collision with #1742)

CI version gate caught: PR #1742 (garrytan/upgrade-gstack-gbrain-v1)
already claims v1.50.0.0 and #1751 (garrytan/browser-memory-leak) claims
v1.51.0.0. gstack-next-version util recommends v1.52.0.0 as the next free
slot.

Updates:
- VERSION 1.50.0.0 → 1.52.0.0
- package.json version sync
- CHANGELOG.md header + metric table label
- parity-baseline-v1.47.0.0.json baseline_note reference

No content changes; pure slot rebase per the queue. The cathedral scope
(8 layers, 96 tests) and CHANGELOG narrative stay identical — same ship,
different release number.

* chore: cap audit — remove distill rate cap, loosen size/budget gates

Plan-tune cathedral follow-up. The 3/day distill cap was theatrical: at
~$0.01 per Haiku call, even a runaway loop firing every minute would cost
~$14/day, and free-text events are rare enough that the natural input
rate self-limits to 1-2 fires/day. Count caps don't protect against
runaway bugs (which fire 1000x/second, not 4 times/day) but DO punish
heavy users who'd legitimately distill multiple times during a busy week.

Removed: 3/day rate cap on bin/gstack-distill-free-text. --status output
swapped from "TODAY: N / 3" to "TODAY: N run(s), $X" so users see what
they're spending instead of how close they are to a meaningless count.

Loosened (caps that exist for real-runaway protection, not normal scope):
- EVALS_BUDGET_HARD_CAP_GATE   $25 → $200/run
- EVALS_BUDGET_HARD_CAP_PERIODIC $70 → $500/run
- EVALS_BUDGET_HARD_CAP        $30 → $300/run (umbrella fallback)
- GSTACK_SIZE_BUDGET_RATIO     1.05 → 1.50 per-skill ratio
- plan-review preamble byte budget 40K → 60K

Principle: caps exist to catch obvious bugs (infinite retry, model price
change, prompt blowup), not to gate legitimate scope growth. Set high
enough that real growth never trips them, only bug territory does.
Adjusted defaults are 4-8× historical worst case, leaving ample headroom
for the next 12 months of legitimate expansion.

Tests updated: distill-free-text removes the 3-test rate-cap describe
block in favor of "no rate cap" assertion that 10 runs/day pass. Other
budget tests still pass because they were never near the old ceilings.

* feat(redact): shared redaction engine + taxonomy (pure lib, no behavior change)

Add the foundation for cross-skill PII/secret/legal redaction:

- lib/redact-patterns.ts — canonical 3-tier taxonomy (HIGH genuinely-secret
  credentials, MEDIUM PII/legal/internal + high-FP credential-shaped, LOW
  surface-only). Tier-1 calibration: Stripe-publishable, Google AIza, JWT, and
  env-KV are MEDIUM not HIGH (context-variable / high-FP). Validators: Luhn,
  Shannon-entropy gate, RFC1918 exclusion, wallet sanity. Per-span placeholder
  suppression (not line-based).
- lib/redact-engine.ts — pure scan() + applyRedactions(). Normalization pass
  (NFKC + zero-width strip + entity decode) with offset map back to original.
  Oversize input fails CLOSED. No visibility-based tier promotion (records
  repoVisibility for sterner wording only). Tool-attributed-fence WARN-degrade
  for obvious doc-examples. Safe preview masking (≤4 leading chars).
- 100 unit tests: per-pattern positives, FP filters, validators, email
  allowlist, no-promotion semantics, tool-fence degrade, normalization,
  oversize-fail-closed, ReDoS pattern-lint + runtime budget, auto-redact
  (idempotent, right-to-left, structural-corruption guard).

* feat(redact): bin/gstack-redact CLI shim over the engine

Skill-facing CLI wrapping lib/redact-engine. Reads stdin or --from-file,
scans, prints JSON (--json) or a human table. Exit codes 0/2/3 gate
dispatch/file/edit/commit (WARN never gates). --auto-redact emits the
sanitized body + diff for the PII-class one-keystroke path. --allowlist,
--self-email, --repo-public-emails, --repo-visibility, --max-bytes.
Fails closed on oversize at the CLI boundary before the engine even reads.

9 contract tests: exit codes, JSON shape, auto-redact, allowlist, self-email,
from-file, oversize-fail-closed.

* feat(redact): opt-in pre-push hook (accident catcher) + safe installer

bin/gstack-redact-prepush scans the diff being pushed for HIGH credentials and
blocks on a hit, for public AND private repos (a pushed secret is compromised
regardless of visibility). Correct git pre-push semantics: scans remote..local
(what's being pushed), handles new-branch zero-SHA via merge-base or empty-tree
fallback, force-push, and branch-delete skip. MEDIUM warns non-blocking; LOW/WARN
silent. GSTACK_REDACT_PREPUSH=skip escape valve logs to prepush-skip.jsonl.

bin/gstack-redact gains install-prepush-hook / uninstall-prepush-hook
subcommands that chain any pre-existing hook (renamed to pre-push.local,
stdin forwarded to both, exit code propagated).

Guardrail not enforcement: --no-verify and the env skip both bypass; it scans
only the pushed delta, not history/binary/LFS. 9 tests in a throwaway git repo.

* feat(redact): gstack-config keys redact_repo_visibility + redact_prepush_hook

redact_repo_visibility (public|private|unknown) is a LOCAL override for repos
gh/glab can't read; it lives in ~/.gstack/config.yaml so it can't weaken the
gate repo-wide for other contributors. redact_prepush_hook (true|false) toggles
the opt-in pre-push hook. No block_private key — HIGH blocks both visibilities
unconditionally. Value-domain validation + 6 tests.

- {{REDACT_TAXONOMY_TABLE}} — 3-tier table for /spec + /cso (shared source).
- {{REDACT_INVOCATION_BLOCK:<sink>}} — the canonical scan-at-sink bash + prose
  for one enforcement point (pre-codex/pre-issue/pre-archive/pre-pr-body/
  pre-pr-title/pre-commit): which-bun probe, visibility resolution (local config
  → gh → glab → unknown), temp-file scan-at-sink, exit 3/2/0 branches, PII
  auto-redact offer, guardrail-not-enforcement framing.

Registered in index.ts. 12 resolver tests. No SKILL.md churn yet (no template
references the placeholders until the per-skill wiring commits).

* feat(spec,cso): wire shared redaction — semantic pass + scan-at-sink + taxonomy

/spec Phase 4.5 rewrite:
- Phase 4.5a: in-conversation semantic content review (named-criticism,
  customer complaints, unannounced strategy, NDA, codename bleed). Injection-
  hardened (a body containing the SEMANTIC_REVIEW marker forces flagged).
  Content-free audit trail to ~/.gstack/security/semantic-reviews.jsonl.
- Phase 4.5b: replaces the inline 7-regex prose with the shared gstack-redact
  scan-at-sink (exact-byte temp file). Three enforcement points: pre-codex,
  pre-issue (files via --body-file from the scanned file), pre-archive (D2:
  sanitized body to the archive). --no-gate skips codex score only; redaction
  always runs, no flag disables it.

/cso: renders the full generated taxonomy table as its canonical pattern catalog
(shared source), keeps its git-history archaeology (different use case).

lib/redact-audit-log.ts: 0600 append-only semantic-review trail (no body text).
Resolver gains compact-table + brief-block variants so /spec references the
catalog instead of inlining it (stays under the v1.47 size budget).

Tests: extended spec invariants (semantic pass, scan-at-sink, no-promotion),
audit-log, cso/spec alignment. All green; spec 1.050× / cso 1.046× baseline.

* feat(ship,document-*): redaction scan-at-sink on PR bodies + generated docs

- /ship: scan the composed PR body + title before create AND edit, from a temp
  file (exact bytes scanned = bytes sent). HIGH blocks the PR (no skip); MEDIUM
  confirms per finding. Codex/Greptile/eval sections go in tool-attributed fences
  so example credentials those tools quote WARN-degrade instead of blocking the
  PR — a live-format credential inside the fence still blocks.
- /document-release: scan the PR-body temp file before gh pr edit.
- /document-generate: scan the staged doc diff (added lines) before commit —
  generated docs often carry example credentials; a live-format secret blocks.

Tests: ship-template-redaction (incl. tool-fence WARN-degrade contract),
document-skills-redaction. All skills stay under the v1.47 size budget.

* feat(redact): semantic-pass eval + CLAUDE.md docs + size/parity baselines

- test/redact-semantic-pass.eval.ts: periodic-tier paid eval (EVALS=1) with 10
  should-flag / should-clean fixtures + an injection-resistance case, the only
  way to detect semantic-pass model drift.
- CLAUDE.md: "Redaction guard" section — engine/CLI/hook locations, the
  guardrail-not-enforcement framing, scan-at-sink, no-tier-promotion, the
  tool-attributed-fence convention, the config keys, and the audit log.
- /cso uses the compact (HIGH-tier) taxonomy table so it fits under BOTH the
  v1.47 and the older v1.44.1 parity ceilings; full MEDIUM/LOW lives in
  lib/redact-patterns.ts. Alignment test asserts the HIGH-tier contract.
- Refresh the ship golden baselines (claude/codex/factory) for the PR-body
  redaction wiring.

Full free suite green (incl. skill-size-budget + parity 10/10).

* v1.52.1.0 feat: brain-aware planning — 5 skills read structured gbrain context before asking (#1742)

* feat(brain): brain-cache-spec.ts — single source of truth for cache layer

Foundation for the brain-aware planning skills work (v1.48 plan / D2).
One TS const file consolidates BRAIN_CACHE_ENTITIES (8 entities × TTL +
budget + invalidation rules), SKILL_DIGEST_SUBSETS (per-skill which
files to load), SALIENCE_DEFAULT_ALLOWLIST (D9 privacy gate),
SKILL_CALIBRATION_WEIGHTS (Phase 2 E5), and policy / identity / schema
constants.

Drift between docs and runtime becomes impossible by construction:
resolver, cache CLI, and test/skill-preflight-budget.test.ts all import
from the same module.

test/brain-cache-spec.test.ts: 19 invariant assertions (subset/entity
consistency, per-skill achievability, allowlist sanity, transport
defaults, user-slug fallback chain, lock timeout, retention policy).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): gstack-core@1.0.0 schema pack (T1 / Phase 0)

Defines 8 typed page kinds for the brain entity model:
  gstack/user-profile, gstack/product, gstack/goal,
  gstack/developer-persona, gstack/brand, gstack/competitive-intel,
  gstack/skill-run, gstack/take

Each declares frontmatter shape (typed fields with required/optional flags),
retention policy (immutable / archive-after-90d / never-archive), and
emits_links graph for mcp__gbrain__schema_graph rendering.

getSchemaPackMutationPayload() returns JSON in the shape accepted by
mcp__gbrain__schema_apply_mutations. Idempotent registration: gbrain
skips when pack+version already installed.

test/gstack-schema-pack.test.ts: 16 invariants on pack shape, retention
policies, link verb consistency, JSON serializability.

* feat(brain): gstack-brain-cache CLI (T2a) — core subcommands

bin/gstack-brain-cache: TS CLI with five subcommands:
  get <entity-name> [--project <slug>]
  refresh [--full] [--entity X] [--project <slug>]
  invalidate <entity-name> [--project <slug>]
  digest <entity-slug>
  meta [--project <slug>]

Cache layout per Phase 0.5 design:
  ~/.gstack/brain-cache/                 ← cross-project (user-profile)
  ~/.gstack/projects/<slug>/brain-cache/ ← per-project (everything else)

Per-entity TTL drives staleness; per-entity byte budgets enforce
compression at write time. Atomic writes via tmp+rename. Stale-but-usable
fallback when brain unreachable (returns cached digest with diagnostic
prefix instead of failing). Schema-version mismatch + endpoint switch
both trigger full rebuild for the affected scope (D4 A4).

Fetch+compress paths wired for the 7 entities (user-profile, product,
goals, developer-persona, brand, competitive-intel, recent-decisions,
salience) via gbrain CLI shell-out — works for local PGLite and
local-stdio MCP, transparent over the existing spawnGbrain helper.

Concurrent-refresh dedup (D3 / T15) is a follow-up commit. Salience
allowlist gate (D9 / T17) is a follow-up commit. Bootstrap + lifecycle
subcommands (T2b / T18) are follow-up commits.

test/brain-cache-roundtrip.test.ts: 11 tests covering path resolution,
meta lifecycle, endpoint detection, schema mismatch behavior, and the
four cache states (warm / cold-refreshed / stale-fallback / missing).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): concurrent-refresh lockfile dedup (T15 / D3)

When autoplan dispatches 4 planning skills back-to-back and they all hit
a cold-miss on the same digest, only ONE actually fetches from the brain.
The rest dedup via the project-scoped lockfile at
~/.gstack/projects/<slug>/brain-cache/.refresh.lock.

Reuses the 5-min stale-takeover convention from /sync-gbrain. Lock is
taken over when:
  - File is older than CACHE_REFRESH_LOCK_TIMEOUT_MS
  - PID is on the same host and dead (process.kill(pid, 0) fails)
  - Lock file is corrupt (defensive)

withRefreshLock(projectSlug, fn) returns either the callback's value or
the literal 'dedup'. The CLI emits exit code 3 + diagnostic stderr on
dedup, so callers can choose to wait + retry (resolver does this) or
fall through to stale-but-usable behavior.

test/cache-concurrent-refresh.test.ts: 7 tests covering acquire/release,
stale-takeover, dead-PID takeover, corrupt-lock recovery, error-path
release, and cross-project lock location.

* feat(brain): salience privacy allowlist gate (T17 / D9)

D9 cross-model finding from codex outside voice: salience-sourced digests
can include emotionally-weighted personal pages (family, therapy,
reflection). Pulling those into a coding-review prompt leaks sensitive
context into work-flow reasoning.

fetchSalience now strips entries whose slugs don't match an allowlist
prefix BEFORE writing to the cache file. Default allowlist is
SALIENCE_DEFAULT_ALLOWLIST = ['projects/', 'concepts/', 'gstack/'].
User can extend via:
  gstack-config set salience_allowlist 'projects/,gstack/,concepts/,custom/'
or override with GSTACK_SALIENCE_ALLOWLIST env var.

Digest still records the strip count for transparency. Empty result
emits 'all N entries stripped' note rather than silent absence.

test/salience-allowlist.test.ts: 9 tests covering default permits,
default blocks, empty allowlist, env override, whitespace trimming,
and the invariant that defaults contain nothing sensitive (personal,
family, therapy, reflection, private, medical, health).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): bootstrap + list + purge subcommands (T2b / T18)

T2b — bootstrap synthesizes draft entity content from CLAUDE.md + README
+ recent learnings.jsonl and emits as JSON for the caller. Skill template
is responsible for the AUQ-confirm-before-write flow (D10 T4 extraction-
review requirement). Cli stays pure (no AUQ logic); agent owns user
interaction.

T18 — list/purge subcommands close the lifecycle loop:
  list [--project <slug>] — enumerate gstack-owned pages in brain
                            (probe all 8 gstack/* page types)
  purge <slug>           — delete one gstack page, refuses non-gstack/
                            slugs (defensive)

list defaults to all-projects (cross-project user-profile included).
With --project, filters to per-project pages plus the cross-project
user-profile. --json flag emits machine-readable output for the agent.

Retention sweep + audit subcommand are deferred to a follow-up commit
(they need the lifecycle scheduling design, not just CLI plumbing).

* feat(brain): brain-aware planning resolvers + 3 new placeholders (T4)

scripts/resolvers/gbrain.ts adds:
  - generateBrainPreflight(ctx)       — emits per-skill ## Brain Context
                                        block + bash that loads digests via
                                        gstack-brain-cache get (one call per
                                        digest). Per-skill subset comes from
                                        SKILL_DIGEST_SUBSETS (single source).
  - generateBrainCacheRefresh(ctx)    — at-skill-end background refresh hook;
                                        non-blocking; warms cache for next run.
  - generateBrainWriteBack(ctx)       — Phase 2 / E5 calibration write-back
                                        with per-skill weight. Gated on
                                        personal trust policy + the
                                        BRAIN_CALIBRATION_WRITEBACK flag.
                                        Includes invalidation bash that busts
                                        affected digests after the write.

scripts/resolvers/index.ts registers three new placeholders:
  {{BRAIN_PREFLIGHT}}, {{BRAIN_CACHE_REFRESH}}, {{BRAIN_WRITE_BACK}}

All three resolvers return empty string for skills not in
SKILL_DIGEST_SUBSETS (defensive — skill template authors can drop the
placeholders into non-preflight skills with zero effect).

D9 privacy is mentioned in the rendered preflight prose so the agent
knows to expect filtered salience.
D11 codex tension: write-back gates on brain_trust_policy@<hash> being
personal — shared brains skip write-back to avoid polluting team
calibration profile.

test/brain-preflight.test.ts: 19 tests covering subset rendering,
non-preflight skill gating, cross-project vs per-project --project flag
emission, weight injection per skill, BRAIN_CALIBRATION_WRITEBACK flag
mention, and registration in RESOLVERS map.

* feat(brain): gstack-config brain integration helpers (T5+T10+T16)

Extends bin/gstack-config to support the brain-aware planning layer:

KEY VALIDATION (T5):
  Plain alphanumeric/underscore now extended to allow @<hex-hash> suffix.
  Required for per-endpoint namespaced keys (brain_trust_policy@<sha8>,
  user_slug_at_<sha8>). Keys without the suffix still validate as before.

VALUE WHITELISTING (D4 / D11):
  brain_trust_policy@* values gated to personal | shared | unset.
  Unknown values warn + default to unset (defense against typos).

NEW DEFAULTS (lookup_default):
  brain_trust_policy@*  -> unset
  salience_allowlist    -> '' (resolver uses SALIENCE_DEFAULT_ALLOWLIST)
  user_slug_at_*        -> '' (resolve-user-slug fills + persists on demand)

NEW SUBCOMMANDS:
  endpoint-hash      — print sha8 of active gbrain MCP URL from
                       ~/.claude.json. Collision check escalates to sha16
                       when a prior endpoint stored at the same sha8
                       would conflict (T10 defensive default).
  resolve-user-slug  — walks D4 A3 identity chain:
                         1. mcp__gbrain__whoami.client_name
                         2. $USER env var
                         3. sha8(git config user.email)
                         4. anonymous-<sha8(hostname)>
                       Persists result on first call so subsequent
                       calls are stable across sessions.

test/user-slug-fallback.test.ts: 14 tests covering endpoint-hash output
shape, fallback chain ordering, persistence, brain_trust_policy
namespace value validation + per-endpoint isolation, and key validator
extension for @-suffixed keys.

* feat(brain): wire 5 planning skill templates with BRAIN_* placeholders (T6)

Adds three placeholders to each of the 5 planning SKILL.md.tmpl files:
  {{BRAIN_PREFLIGHT}}     — top of skill body, before first interactive
                            section. Loads the per-skill digest subset
                            (5 files for office-hours, 2 for plan-eng-
                            review, etc.) into the prompt context before
                            any AskUserQuestion fires.
  {{BRAIN_WRITE_BACK}}    — end of skill, before refresh hook. Phase 2
                            calibration write path; gated on personal
                            policy + BRAIN_CALIBRATION_WRITEBACK flag.
  {{BRAIN_CACHE_REFRESH}} — end of skill, after write-back. Non-blocking
                            background refresh so next invocation gets
                            warm cache.

Files touched (templates + regenerated SKILL.md):
  office-hours/SKILL.md.tmpl
  plan-ceo-review/SKILL.md.tmpl
  plan-eng-review/SKILL.md.tmpl
  plan-design-review/SKILL.md.tmpl
  plan-devex-review/SKILL.md.tmpl
  (matching .md files regenerated via bun run gen:skill-docs)

All 5 generated SKILL.md files now contain the rendered ## Brain Context
(preflight) section + write-back guidance + background-refresh hook. The
resolver renders only for skills in SKILL_DIGEST_SUBSETS — these 5 + an
empty string for any other skill that drops in the placeholders.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): setup-gbrain trust-policy step + sync-gbrain flags (T5b / T13+T5c)

T5b — setup-gbrain Step 9.5:
  Inserts the brain trust policy AskUserQuestion before the verdict block.
  Detects active endpoint hash via gstack-config endpoint-hash. Branches
  per transport:
    * Local (sha == "local"): auto-set personal, one-line notice
    * Remote-MCP, unset: AskUserQuestion (personal vs shared)
    * Already-set: skip, just print current policy
  Personal default flips artifacts_sync_mode=full when still off.

T13+T5c — sync-gbrain:
  Adds two flag short-circuits:
    --refresh-cache : route to gstack-brain-cache refresh --project <slug>;
                       skip code + memory + brain-sync stages. Replaces
                       the planned /brain-refresh-context skill per D1
                       fold (one fewer always-loaded skill in catalog).
    --audit          : emit gstack-owned page summary + sensitive-content
                       leak check via gstack-brain-cache list. Read-only.
  Step 1 trust policy gate: fires the same AskUserQuestion as setup-gbrain
  Step 9.5 when policy is unset for a remote endpoint. Local engines
  auto-set personal silently. Idempotent for already-set policies.

Both templates re-rendered via bun run gen:skill-docs. Trust policy
question wording centralized in setup-gbrain Step 9.5; sync-gbrain
Step 1 references it to avoid prompt drift.

* test(brain): schema migration + fence-block fallback + preflight budget (T19+T21)

3 new gate-tier test files closing the most important coverage gaps in
the brain-aware planning layer:

test/schema-version-migration.test.ts (D4 A4):
  - Cache file with mismatched schema_version triggers wipe-and-rebuild
  - Matching version + fresh TTL stays warm-hit (no unnecessary rebuild)
  - Rebuild wipes ALL files in scope, not just the one being read

test/takes-fence-fallback.test.ts:
  - Every preflight skill mentions both takes_add (preferred) and
    put_page fence-block (fallback for pre-T8 gbrain versions)
  - All 5 skills gate on BRAIN_CALIBRATION_WRITEBACK flag + personal
    trust policy
  - Per-skill weight matches SKILL_CALIBRATION_WEIGHTS (E5)
  - Write-back emits the kind=bet frontmatter shape and invalidates
    affected cache digests

test/skill-preflight-budget.test.ts (T21 / D7):
  - Per-skill BRAIN_* instruction bytes stay under 3x the runtime
    digest budget (resolver bloat catch)
  - Autoplan total instruction bytes stay under 75 KB (3x of 25 KB
    runtime cap)
  - Non-preflight skills emit zero brain bytes
  - Per-skill subset references are present in the preflight bash

Note on the 3x multiplier: SKILL_PREFLIGHT_BUDGET_BYTES governs runtime
digest data (enforced by cache CLI truncateToBudget). Instruction text
emitted by the resolver gets a separate 3x headroom — anything beyond
that signals the instructions themselves are bloated and need a trim.

* docs(todos): brain-aware planning follow-ups (T11)

Adds five deferred items from the v1.48.0.0 brain-aware planning plan:

  - P2: /gstack-reflect nightly synthesis skill (E2, deferred D4)
  - P3: cross-machine brain-cache sync (E3, deferred D5)
  - P3: /gstack-onboarding dedicated skill (E4, deferred D6)
  - P2: upstream gbrain takes_add + takes_resolve MCP ops (T8 wrap-up)
  - P3: background-refresh hook supervision (codex outside-voice T3)

Each entry follows the TODOS.md format: What / Why / Pros / Cons /
Context / Effort / Depends on. Each cross-references the v1.48.0.0
review decision (D-numbers from /plan-ceo-review and /plan-eng-review)
that deferred it.

The plan itself is at ~/.claude/plans/hm-interesting-well-why-dapper-eagle.md
and is NOT a TODO entry (it's a one-shot design doc, not ongoing work).

* test(brain): bump schema-migration test timeout to 60s

Rebuild path fans out to 7 per-project entity refreshes, each shelling
gbrain with 10s internal timeout. Worst case ~70s. Default bun test
5s was timing out on slow brain unreachable cases.

* chore: bump version and changelog (v1.50.0.0)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(test): tighten put_page regression pin to CLI subcommand

The test asserted no substring 'put_page' anywhere in the resolver,
but the BRAIN_WRITE_BACK resolver legitimately references the MCP op
`mcp__gbrain__put_page` as the fallback path for calibration takes
when gbrain v0.42+'s `takes_add` op isn't available. The check
conflated the deprecated `gbrain put_page` CLI subcommand (renamed in
v0.18+ to `gbrain put`) with the still-valid MCP op of the same name.

Narrow the assertion to `gbrain put_page` (with the space) so the
fallback prose stays legal while the CLI rename regression stays caught.

* feat(brain): gstack-config gbrain-refresh subcommand

Adds a new subcommand that re-detects gbrain installation state and
persists the result to ~/.gstack/gbrain-detection.json. The detection
file is consumed by gen-skill-docs --respect-detection (next commit)
to decide whether to render the GBRAIN_CONTEXT_LOAD and
GBRAIN_SAVE_RESULTS resolver blocks in user-local SKILL.md generation.

Reuses the existing bin/gstack-gbrain-detect helper for the actual
probe; this subcommand just persists + summarizes. Users run it after
installing or uninstalling gbrain so their locally generated SKILL.md
files match their installation state.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): gen-skill-docs respects gbrain-detection override

Adds --respect-detection flag (and bun run gen:skill-docs:user script).
When the flag is set, gen-skill-docs reads ~/.gstack/gbrain-detection.json
and filters GBRAIN_CONTEXT_LOAD + GBRAIN_SAVE_RESULTS out of each host's
suppressedResolvers when gbrain_local_status is "ok". When absent or
gbrain isn't detected, suppression behaves as before.

The default `bun run gen:skill-docs` (CI canonical) ignores the
detection file so the committed SKILL.md stays reproducible regardless
of any developer's local gbrain installation state. Use
gen:skill-docs:user for user-local installs (./setup invokes it).

No host config files modified — the static suppressedResolvers stay
correct for the no-gbrain case; the override happens at gen-time.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(brain): setup runs gbrain detection + conditional SKILL.md regen

At the end of install, ./setup now:
  1. Runs bin/gstack-gbrain-detect, persists the result to
     ~/.gstack/gbrain-detection.json
  2. If gbrain_local_status == "ok", regenerates Claude-host SKILL.md
     via `bun run gen:skill-docs:user --host claude` so the user's
     local install picks up the compressed brain-aware blocks
  3. If gbrain isn't detected, leaves the canonical no-gbrain SKILL.md
     files in place (zero token overhead) and surfaces the
     gstack-config gbrain-refresh path for users who install gbrain
     later

Together with the prior two commits, this completes the setup-time
conditional un-suppression: brain-aware blocks render iff the user
has gbrain installed, regardless of which CLI host they're on.

* refactor(brain): compress GBRAIN_* resolvers, move template prose to docs/

generateGBrainContextLoad: 80 -> 115 tokens with explicit skip-header.
generateGBrainSaveResults: 500-700 -> 161 tokens per skill with the
skill metadata extracted into a typed skillSaveMap (slugPrefix + title
+ tag). Verbose prose (heredoc body, entity-stub instructions, throttle
handling, backlink protocol) moved into a new doc:
docs/gbrain-write-surfaces.md (Sections: §Context Load, §Save Template).
The agent reads the doc on-demand only when actually saving — one Read
call, cached by Claude's context.

Net per-planning-skill overhead under un-suppression drops from ~1000
tokens (naive un-suppression) to ~275 tokens (compressed). Combined
with the setup-time detection from prior commits, users WITHOUT gbrain
pay zero overhead (block suppressed at gen-time) and users WITH gbrain
pay ~275 tokens.

The /investigate special-case (data-research routing in CONTEXT_LOAD)
stays inline since it's skill-specific.

docs/gbrain-write-surfaces.md also serves as the manual-probe reference
for humans verifying live persistence + a topology summary covering
trust-policy + .gbrain-source reads-only semantics.

* feat(brain): wire SAVE_RESULTS for plan-design-review + plan-devex-review

Adds {{GBRAIN_SAVE_RESULTS}} placeholder to the two planning skills
that were missing it, immediately before {{BRAIN_WRITE_BACK}} (mirrors
plan-eng-review:324 + office-hours:650). The corresponding skillSaveMap
entries (design-reviews/<feature-slug> + devex-reviews/<feature-slug>)
landed with the resolver compression in the prior commit.

Regenerated SKILL.md reflects the new placeholder position. The
default no-gbrain generation (CI canonical) still suppresses the
block — zero diff in the rendered output for non-gbrain users.

All five planning skills now write a retrievable review page to gbrain
when gbrain is detected at setup time, instead of three of five.

* test(brain): resolver compression + detection-override regression pins

test/resolvers-gbrain-save-results.test.ts (140 LOC, 10 tests):
  - Per-skill assertions for all 5 planning skills: emits gbrain put +
    correct slug prefix + tag + title.
  - Skip-header present so agent can short-circuit when gbrain isn't
    on PATH.
  - Compression pin: each per-skill block stays under 750 chars
    (~190 tokens) — guards against a future "let me add one more
    line" refactor silently re-inflating toward the ~1000-token naive
    un-suppression baseline.
  - Generic fallback for unmapped skill names still works.
  - /investigate gets the data-research routing suffix; non-investigate
    skills do not.
  - generateGBrainContextLoad stays under 500 chars (~125 tokens).

test/gbrain-detection-override.test.ts (120 LOC, 4 tests):
  - End-to-end through gen-skill-docs subprocess against an isolated
    temp GSTACK_HOME. Asserts:
    * detected:true un-suppresses GBRAIN_* → SKILL.md gains the block
    * detected:false (status != "ok") suppresses → no block
    * no detection file suppresses → no block (graceful default)
    * no --respect-detection flag IGNORES the detection file → no
      block (CI canonical path stays reproducible)

Each detection-override test restores the canonical SKILL.md in a
finally block so the working tree stays clean.

* test(brain): fake-CLI agent-obedience E2E for /office-hours writeback

test/skill-e2e-office-hours-brain-writeback.test.ts (~210 LOC,
periodic-tier, ~$0.50-1/run):

Drives /office-hours via runSkillTest against a deterministic fixture
brief (pixel.fund founder pitch). The workdir has:
  - A regenerated office-hours/SKILL.md with the compressed brain blocks
    (generated via gen-skill-docs --respect-detection against a temp
    GSTACK_HOME, then restored to canonical post-snapshot)
  - A fake gbrain shell script on PATH that uses printf %q quoting to
    preserve --content "$(cat <<'EOF' ... EOF)" heredoc payloads
    intact (naive `echo "$@"` would lose argv boundaries)
  - The docs/gbrain-write-surfaces.md the resolver points to

Asserts:
  - gbrain-calls.log contains `gbrain put office-hours/pixel-fund`
  - Payload file at gbrain-payloads/office-hours/pixel-fund.md exists
    with valid YAML frontmatter (title: + tags: + design-doc tag)
  - At least one gbrain put entities/<name> call (entity stub
    enrichment is best-effort, soft warning if absent)

Covers agent obedience to the SAVE_RESULTS instruction. Out of scope:
gbrain CLI persistence contract (T11 covers that with real PGLite).

* test(brain): real PGLite round-trip E2E (matched-pair persistence)

test/skill-e2e-gbrain-roundtrip-local.test.ts (~145 LOC, periodic-tier,
~$0.001/run on Voyage):

Real gbrain CLI round-trip against an isolated temp HOME:
  1. gbrain init --pglite --embedding-model voyage:voyage-code-3
  2. gbrain put office-hours/<unique-slug> --content <markdown>
  3. gbrain get <slug>
  4. Assert every body line survives + title + tags + non-empty

This is the matched-pair check for the v1.50.0.0 question "is the data
we hope to save actually being saved?" — proves the gbrain CLI
persistence contract gstack relies on, against a real engine.

Does NOT involve the agent — pure CLI integration test. The agent
obedience side is covered by the fake-CLI E2E in the prior commit.

Skips cleanly when VOYAGE_API_KEY is unset OR gbrain CLI is missing
from PATH, so CI without secrets degrades gracefully.

Remote/Supabase routing is gbrain's contract — the same CLI shape
works against every engine. gstack stops at local round-trip coverage
to avoid re-testing gbrain's MCP client implementation.

* chore(brain): touchfiles + TODOS + CHANGELOG for v1.50.0.0

test/helpers/touchfiles.ts: register the two new E2Es in
E2E_TOUCHFILES + E2E_TIERS (both periodic):
  - office-hours-brain-writeback: triggered by resolver / gen-pipeline /
    detection helper / refresh subcommand / office-hours template /
    docs / fixture / test file changes
  - gbrain-roundtrip-local: triggered by resolver / test file changes

TODOS.md: append two P2 follow-ups carried over from the v1.50 plan:
  - Re-verify calibration takes when gbrain v0.42+ ships takes_add and
    BRAIN_CALIBRATION_WRITEBACK flips TRUE
  - Extend brain-writeback E2E to the other 4 planning skills (extract
    makeFakeGbrain to test/helpers/fake-gbrain.ts when second consumer
    arrives)

CHANGELOG.md v1.50.0.0: add a "Save-results path: works under any CLI
when gbrain is on PATH" section that documents the headline:
  - Conditional inclusion at setup-time (zero overhead for non-gbrain
    users, ~250 tokens with gbrain)
  - Wiring symmetry fix (5 of 5 planning skills now write a page)
  - Token cost table comparing detection states
  - Test coverage map (resolver unit + override mechanism + fake-CLI
    agent obedience + real PGLite round-trip)
  - Why remote routing isn't tested here (gbrain's contract)

* test(brain): tighten prompt + relax slug assertion in writeback E2E

Two fixes:

1. Prompt: "Slug it 'pixel-fund'" was ambiguous — agent could read it
   as "use pixel-fund as the FULL slug" instead of "substitute
   pixel-fund for <feature-slug>". Replaced with explicit guidance:
   "The feature-slug value to substitute into the SAVE_RESULTS
   template's <feature-slug> placeholder is exactly 'pixel-fund' (no
   path prefix — the template already provides the prefix). Apply the
   SAVE_RESULTS template literally." Also added "Do NOT explore gbrain
   --help" to short-circuit the discovery loop the agent fell into.

2. Slug assertion: was a strict /gbrain put .*office-hours\/pixel-fund/
   regex. This conflated two concerns — agent obedience (does the
   agent actually invoke gbrain put?) vs resolver output shape (does
   the template emit the right prefix?). The latter is already pinned
   by test/resolvers-gbrain-save-results.test.ts at the resolver level
   (free, hermetic). The E2E now asserts /gbrain put .*pixel-fund/
   (slug contains pixel-fund somewhere) plus a recursive payload-file
   search that accepts either office-hours/pixel-fund.md (template-
   faithful) or pixel-fund.md (agent dropped prefix). The YAML
   frontmatter + tag assertions on the payload remain strict — those
   are the real agent-obedience contract.

3. Entity-stub regex: was looking for entities/<name>; agent
   variability uses entity/<name>, people/<name>, companies/<name>.
   Loosened to match entit(y|ies) only. The soft-warning path stays
   (no hard fail) because entity extraction is best-effort prose, not
   a CLI contract.

Verified passing locally: 7 expect() calls, 268s, ~$0.50.

* chore: bump version to 1.51.1.0

main advanced to 1.51.0.0 while this branch was in development. Bump
to 1.51.1.0 (PATCH above main) so the branch lands cleanly above the
current main version per the monotonic-ordered-release invariant.

Renames the branch-internal [1.50.0.0] CHANGELOG entry to [1.51.1.0] —
1.50.0.0 never landed on main (main skipped to 1.51.0.0), so this
consolidates the branch's brain-aware planning + save-results work
under a single shipping version with no orphaned entry.

* v1.52.2.0 fix(make-pdf): render emoji instead of tofu (▯) on Linux (#1787)

* fix(make-pdf): emoji font fallback in print CSS

Emoji code points rendered as .notdef tofu (▯) because the body and
@top-center font stacks had no emoji family for Chromium to fall back to.
Add SANS_STACK / CJK_STACK / EMOJI_FAMILIES constants (one source of truth
per family list) and append the emoji families before the generic
sans-serif in the two stacks that can hold emoji. The @bottom-* boxes hold
counters / a fixed CONFIDENTIAL string, so they share SANS_STACK without
emoji. Non-emoji output is byte-identical.

* feat(setup): auto-install color-emoji font on Linux

macOS and Windows ship a color-emoji font; most Linux distros/containers
ship none, so make-pdf emits tofu there. ensure_emoji_font() best-effort
installs fonts-noto-color-emoji (apt, with dnf/pacman/apk fallbacks) and
refreshes the fontconfig cache. Hardened: Linux-only guard, GSTACK_SKIP_FONTS
escape hatch, fc-match color=True detection (the broad fc-list query
false-matched LastResort), sudo -n so a password prompt fails fast instead
of hanging, DEBIAN_FRONTEND=noninteractive, timeout 30 on apt update, and
fc-cache under sudo. Warns instead of failing. After a fresh install,
refresh_browse_daemon_for_fonts() runs 'browse stop' so the next render
spawns a Chromium that sees the new font (font fallback is process-cached).

* test(make-pdf): emoji render gate (pdffonts + pixel proof)

pdftotext is a false oracle for emoji: Skia preserves the Unicode in the
text cluster even when the glyph drew as .notdef tofu, so extraction passes
on a broken render. The gate instead asserts (1) pdffonts shows an emoji
family embedded and (2) pdftoppm rasterizes the page to color (measured
~1650 saturated pixels vs ~0 for tofu). pdfimages is not used: macOS embeds
color emoji as Type 3 fonts, so it lists nothing even on a correct render.
Adds resolvePopplerTool() (DRY resolver, returns null for clean skips) and
a fixture exercising FE0F variation-selector emoji. Skips cleanly when
poppler tools or a color-emoji font are unavailable.

* ci(make-pdf): install emoji font + run emoji gate on Ubuntu

Install fonts-noto-color-emoji before Chromium launches on the Ubuntu leg
(macOS already ships Apple Color Emoji), refresh fontconfig, and log the
fc-match result. Run the whole make-pdf/test/e2e/ dir so the emoji gate runs
alongside the combined-features copy-paste gate.

* harden(make-pdf): emoji gate + font install per adversarial review

Codex adversarial pass on the implementation diff flagged five robustness
gaps, all fixed here:
- emoji-gate skipped green in CI when poppler/font prerequisites were absent,
  which could let the tofu regression ship behind a green build. Missing
  prerequisites are now a HARD FAILURE when process.env.CI is set; local dev
  still skips cleanly.
- execFileSync children (make-pdf, pdffonts, pdftoppm, fc-match) had no
  timeout; a wedged binary or hostile GSTACK_*_BIN override could hang the
  job past Bun's test timeout. Each child now has a 25s ceiling.
- PPM parser trusted header tokens blindly; malformed/variant output gave a
  silently-wrong count. Now validates magic/dimensions/maxval and pixel-buffer
  length, handles header comments, throws a hard diagnostic on mismatch.
- predictable /tmp paths were collision/symlink-prone; now mkdtempSync under
  /tmp (kept under /tmp for browse's validateOutputPath allowlist).
- only apt-get update was timeout-wrapped; dnf/pacman/apk installs and apt
  install can hang on locks/mirrors. All package installs now timeout-bound.

* docs(make-pdf): document color-emoji font requirement + GSTACK_SKIP_FONTS

Extend the Linux font note to cover the color-emoji font that make-pdf
emoji rendering needs: setup auto-installs fonts-noto-color-emoji, the
print CSS falls back through Apple/Segoe/Noto emoji families, and
GSTACK_SKIP_FONTS=1 opts out. Edit the .tmpl and regenerate SKILL.md.
