Garry TanandClaude Fable 5.1 e60cd924a9 fix(gstack-memorable): stale-lock reclaim checks the inode it judged and the owner's liveness; status reports a failed receipt query as unknown

Garry TanandClaude Fable 5.1 73245d8e1d fix(hooks): outside-model review fixes for the memorable hook and runExternal 
- Nothing in the vendor's process group outlives the call: the group is
  killed on every resolve, the clean 'close' path included (a helper the
  vendor forked with redirected stdio ran on unsupervised before).
- A child that already exited when the deadline fires keeps its result; the
  deadline only ends the drain instead of rewriting a completed exit as a
  timeout.
- The decoded-leaf scan reports when its node/depth bound cut the walk short
  and the hook refuses the hand-off as unscanned; object keys are scanned too.
- git for the trust-policy lookup runs without inherited GIT_* selectors
  (GIT_DIR, GIT_WORK_TREE, GIT_CONFIG_*), so it inspects the session's
  repository and no other; a host cancellation kills that git as well.
- An unmatched brace in a vendor banner no longer hides the answer after it.
- The stderr tail is scanned whole before it is cropped for the log, so a
  credential's prefix cannot be cropped away from its secret half.
- The vendor override reads an empty GSTACK_MEMORABLE_BIN as unset, exactly
  as bin/gstack-memorable does, so enable checks the binary the hook runs.

Garry TanandClaude Fable 5.1 1b9d0d11f0 test: deterministic stdin EPIPE case for runExternal (child closes stdin, stays alive) 
Under parallel shard load a child that merely exits fast raced the write and
the EPIPE was not always observed; closing the read end first makes it so.

Garry TanandClaude Fable 5.1 85dad4211e fix(gstack-memorable): failed stale-lock takeover reaches the give-up; disable runs without gstack-config; status shows ledger size

 2026-09-09 03:45:56 +00:00
Garry TanandClaude Fable 5.1 3b6a859c79 fix(hooks): memorable hook survives host termination and brace-bearing banners 
- The bash shim runs bun as a job and forwards SIGTERM/SIGINT/SIGHUP (bash
  holds a signal until a foreground child exits); the .ts kills the in-flight
  vendor's process group on the way out (runExternal exposes the group kill
  through onSpawn), so a hook the host terminates cannot leave the vendor
  running with the prompt on its stdin.
- The tolerant stdout parser tries every complete top-level object (bounded)
  and takes the first carrying a string additionalContext, so a banner with
  braces or quotes, or a progress object, no longer costs the answer.
- git runs with LC_ALL=C and the not-a-repository check is anchored to the
  start of its message: a localized git or a repository path containing the
  phrase can no longer flip the lookup.
- The rate limiter remembers up to 32 live keys, so alternating failures cost
  two lines, not one per prompt.
- Unicode format characters (bidi overrides, zero-width spaces) are stripped
  from vendor text at egress; the zero-width joiner stays for emoji.
- A killed child (timeout, ENOBUFS) resolves on exit without the stdout drain,
  and the post-kill grace is 100 ms, so the timeout outcome fits the reserve.
- The ledger size warning, which the host discards from an exit-0 hook's
  stderr, is logged where status looks.

Policy lookup outcomes (plain dir, repo without policy, corrupt .git/config
fails closed); repoPolicyTier timeoutMs; line/col at line starts, after blank
lines, CRLF and first char; tolerant first-JSON-object parsing; keyed rate
limit; uninstall never creates a config just to say off and flips consent in
a GSTACK_STATE_ROOT outside the removed state dir.

Garry TanandClaude Fable 5.1 abf5d96400 fix(gstack-memorable): stale-lock takeover by atomic rename; comments match behaviour 
Two contenders that both saw a stale lock could both reclaim it with rm -rf;
the settings-hook idiom (mv to a private name, exactly one winner) is used
instead. The hook-manager fallback comment now says every verb falls back.

Garry TanandClaude Fable 5.1 af72e3d4ff fix(hooks): memorable hook second-pass review fixes 
- Trust-policy lookup fails closed on any git failure that is not 'no such
  remote' or 'not a git repository' (a corrupt or unreadable .git/config and
  dubious ownership exit 128 and used to read as 'no remote').
- pickAdditionalContext takes the first complete top-level JSON object, so a
  vendor whose background helper appends a line to stdout (or prints a banner
  first) does not lose its answer.
- The hook-errors.log rate limiter keys on a stable string (a vendor's
  timestamped stderr no longer defeats it); the log is chmod 0600 on every
  append because sibling hooks create the same file without a mode.
- Scan admission is sized by payload bytes (scan() is uninterruptible).
- The receipt payload class is a stable token; the prose moved to the docs.
- Header, constants and comments match the behaviour (silent skips vs logged
  refusals; HIGH/MEDIUM withholding; STAGE_CAP_MS scope; runExternal in the
  spawn-bin header; the ledger lock budget doc).

Garry TanandClaude Fable 5.1 16af019e42 fix(uninstall): memorable_recall goes off whether or not state is kept 
gstack-config resolves its root through GSTACK_STATE_ROOT/GSTACK_HOME, which
can differ from the STATE_DIR uninstall removes; a full uninstall could leave
memorable_recall=on in a config that survived. Flipped only when currently on.

Garry TanandClaude Fable 5.1 391bc8445f fix(gstack-memorable): lock staleness from the directory mtime; honest messages 
- A contender that looked between the holder's mkdir and its ts write read a
  missing ts as 0, called the lock stale and reclaimed it; staleness now comes
  from the lock directory's own mtime (the settings-hook idiom).
- The ensure-event failure is no longer labelled 'warning'; the consent-write
  rollback message says what was actually kept; a removal that left no entry
  is reported on stdout, not as an error; receipts are counted from the
  filtered JSON array, not a formatting artefact; the resolution order and
  lock tuning are named once.

Garry TanandClaude Fable 5.1 4abb8847a4 fix(hooks): memorable hook closes the review army's gaps 
- Vendor failures are logged even with empty stderr (a silently hanging
  vendor taxed every prompt invisibly); the stderr tail is withheld when the
  redaction engine finds a credential or PII shape in it; hook-errors.log is
  created 0600.
- Trust-policy veto fails closed when git cannot run or answer in time (it
  read as 'no remote' before); the policy script spawn is bounded by the
  hook's clock; a payload cwd that is not a directory falls back.
- Each secret scan is admitted by the deadline clock (the engine's cost grows
  with match density); stdin is decoded once.
- The pre-spawn gate re-check logs a config failure instead of swallowing it;
  an incomplete stdin read is named as such, not as 'not JSON'.
- Carriage returns are stripped with the other controls.
- The vendor env allowlist adds the standard proxy, TLS and XDG variables so
  a vendor behind a corporate proxy or private CA still reaches its service.
- A stdin EPIPE on a delivered answer is recorded in the outcome, not treated
  as a spawn error.
- Stage caps and the truncation marker are named constants; a test-only
  GSTACK_MEMORABLE_TEST_BUDGET_MS can shorten (never widen) the budget.

Garry TanandClaude Fable 5.1 0cefaeadf9 fix(spawn-bin): runExternal resolves on the child's exit, keeps stdin errors advisory 
- A vendor that exits 0 but leaves a background child holding its pipes was
  held to the deadline, group-killed and reported as a timeout with its
  answer dropped. 'exit' now starts a short stdout drain, then resolves with
  the real exit code and kills whatever still holds the group.
- EPIPE on the child's stdin (it answered before reading a large input) is
  reported as stdinError, separate from error, so a delivered answer is not
  classified as a spawn failure.
- Stdio streams are destroyed and the child unref'd on resolve so a straggler
  cannot pin the hook process; tail/grace/drain sizes are named constants.

The policy script spawn was fixed at 10 s, more than twice the memorable

per scan, on the first finding, and each finding is a binary search.

The README section becomes one row in the Standalone binaries table (the
shape every other binary uses) plus a Docs-table row and one Privacy
bullet saying that optional third-party bridges are off by default and
receipted. The guide now separates the two consents, says what gstack
hands to the vendor binary and what the receipt can and cannot attest,
attributes every statement about the vendor's network activity to the
vendor, describes the hook manager accurately (identity via KNOWN_HOOKS,
list-items vs list-sources, rollback is whole-file), states the Claude
Code hot-reload behaviour, adds a troubleshooting runbook, and keeps the
contributors' credit in the CHANGELOG idiom.

Garry TanandClaude Fable 5.1 0eaff4b376 feat(egress): memorable-recall row in gstack-egress grants 
`gstack-egress grants` promises every standing consent in force with the
command that revokes it. The Memorable bridge's memorable_recall key is
one, so it gets a row: off by default, granted only when
`gstack-memorable enable` set it, revoked by `gstack-memorable disable`.

Garry TanandClaude Fable 5.1 ae706a6168 fix(uninstall): named gstack-memorable arm, vendor-consent notice, honest kept config 
The identity sweep already removed the Memorable bridge hook as an
unnamed stray. It now has a named arm like every other source, so the
summary says what went, and says plainly that Memorable's own consent
(if the user granted it) is theirs to revoke. Under --keep-state the kept
config is set memorable_recall=off so it never claims a hook that is
gone. The canonical-paths pins cover the sixth KNOWN_HOOKS row and the
new uninstall source.

Garry TanandClaude Fable 5.1 6aa9cd9e35 fix(setup): --no-team sweep keeps the opt-in gstack-memorable hook 
`./setup --no-team` finishes its teardown with `prune-stale --all`, which
removes every KNOWN_HOOKS item. The Memorable bridge hook is a
user-registered opt-in unrelated to team mode, exactly like verify-gate,
so it joins the sweep exclusion list. The verify-gate pin now accepts the
comma-extended list; a schema-aware case proves the exclusion keeps both
opt-ins (tagged or tag-stripped) while the uninstall sweep still removes
them.

Garry TanandClaude Fable 5.1 05b97dbe6d fix(gstack-memorable): canonical hook path, no vendor consent, --timeout 5, identity-based status, verified disable, lifecycle lock 
enable used to bake the hook path from whatever tree the CLI ran in and
to run the vendor's own `memorable enable` (its consent for storing AND
uploading session traces) before registering anything. It now resolves
the canonical install like setup does and refuses when that install does
not carry this bridge (version and hook-twin check), registers through
the canonical hook manager with --timeout 5, records gstack's own consent
in memorable_recall, never executes the vendor, and restores the captured
prior state if consent cannot be recorded. disable flips the gate first,
removes the entry by identity (tag or no tag), verifies both states and
reports partial failure instead of a blended success. status reads only:
resolution path, gate, registration by identity (gstack / vendor-own /
both / unknown), mismatch lines, receipt count, recent hook errors. enable
and disable serialise under a lock with stale takeover. Windows is
refused (TODOS.md D21). Exit codes mirror the hook manager (3/4/5).

Garry TanandClaude Fable 5.1 d4dbeb6d42 feat(hooks): memorable-user-prompt-hook.ts — consent gate, deny veto, HIGH-tier pre-scan, fail-closed receipt, trust envelope; runExternal in spawn-bin 
The PR's hook exec'd the vendor binary with the full environment and
passed its stdout to Claude verbatim. It is now the house pattern: a
fail-open bash shim over a .ts twin that (1) gates on the memorable_recall
consent key, (2) skips repos whose trust policy is deny or read-only,
(3) scans the prompt (raw bytes and decoded string leaves) and refuses to
hand over a HIGH-tier credential shape, (4) writes a fail-closed egress
receipt naming the local executable it ran, (5) spawns the vendor in its
own process group with an allowlisted environment and group-kills it on
timeout, (6) accepts only a string additionalContext back, caps it at
8 KiB on a UTF-8 boundary and wraps it in the trust envelope, and (7)
records an `output-written` outcome after the stdout write completes.
One deadline clock (4.5 s) undercuts Claude Code's 5 s kill and bounds
both ledger writes through the new lockBudgetMs option on
writeReceipt/writeOutcome (default unchanged).

spawn-bin gains runExternal for external executables (detached group,
stderr drained, stdin EPIPE handled, stdout capped, win32 refused).
The wiring test pins the sink fail-closed and sweeps hosts/.

Garry TanandClaude Fable 5.1 3034769813 feat(config): memorable_recall consent key (on|off, default off, reject-and-preserve) 
The gstack-side gate for the Memorable UserPromptSubmit bridge. `on` lets
a Claude Code hook hand every prompt to a third-party binary, so the key
follows the codex_reviews rule: an invalid value is rejected and the
stored value kept, never coerced in either direction. Registered in all
four places gstack-config keeps in sync (annotated header, DEFAULTS
table, the set validator, and both enumeration loops). Memorable's own
capture consent (`memorable enable`) is a separate thing gstack never
sets.

Garry TanandClaude Fable 5.1 6259b37e48 feat(settings-hook): identity-aware remove-source + read-only list-items 
remove-source used to inspect only entries still carrying the
_gstack_source tag. Claude Code strips that tag when it rewrites
settings.json, so an off switch built on remove-source alone silently
no-oped on exactly the entries it was written for. Removal is now driven
by KNOWN_HOOKS identity for the requested source (tagged or not), keeps
the tagged-single-item legacy-stray rule, never touches another source's
items, and leaves entries with nothing of ours byte-identical.

list-items is the read-only view of the same identity table: one JSON
string literal per matching hook command, filters (--owned-by,
--command-regex as a JavaScript RegExp) applied inside the JS, empty
stdout for no match, and the mutating verbs' exit codes (1 usage, 3
unparseable settings, 4 unexpected shape) so callers can decide
mutations from its output without parsing raw command strings.

Nikhil Krishnaswamy 87eb4ded5d docs: a guide for the Memorable bridge, in the gbrain-sync shape 
README carries the section and the egress table; this is the page it links to
for anyone who wants the whole thing. Same shape as docs/gbrain-sync.md, which
is the closest thing in the repo: an optional integration whose interesting
questions are all about what leaves the machine and how to turn it off.

What it covers that the README cannot at that length: that the hook sees every
Claude Code prompt rather than only the ones a skill produced; that capture is
a separate consent from this bridge, so turning the bridge off does not turn
capture off; what to do when Memorable has already registered the hook itself,
which is the common case because its own installer does it; and why the hook
has no loud failure path.

The egress table is repeated here rather than linked, because the sentence it
is answering ("what does this send") is the one somebody arrives on this page
already asking.

Nikhil Krishnaswamy 01c5ff2791 fix: refuse the second registration, and say what leaves the machine 
Two things the first cut got wrong.

Memorable's own installer registers the same UserPromptSubmit hook, under its
own name and outside gstack's table. `memorable start`, `memorable setup` and
`memorable install-hooks` all do it, and that is the documented way to install
the CLI, so on most machines it is already there before gstack is asked.
Registering ours beside it ran the same command twice on every prompt: context
injected twice, and the session captured twice against the user's own
extraction allowance. `enable` now looks for it and refuses, naming the entry
and the file it lives in; `status` says who registered it rather than reporting
none. Matched on the command rather than on a tag, for the reason the hook
table already gives: Claude Code rewrites settings and private tags do not
survive it.

The removal instruction says to delete the entry by hand because Memorable has
no command that removes its own hook. `uninstall-hooks` is not a command in
0.5.18; it answers "unknown command".

The README said "Memorable, not gstack, owns the captured data and any network
access", which answers the question by pointing away from it. It now carries a
per-command table of exactly what leaves the machine, in the shape the adopted
gbrain section uses, and it is explicit that the hook makes no network call of
its own, that every row is the third-party CLI acting under its own consent,
and that `gstack-egress` will therefore not show any of it. Under it, the split
between what gstack pin-tests (the gating and the wiring) and what is
Memorable's claim (storage, sending, and what disable and forget erase).

The CHANGELOG entry is removed. This file has never carried an [Unreleased]
heading; every entry is a version and a date, written at release. The text is
in the pull request for whoever cuts the next one.

Three tests added: enable refuses and touches neither consent nor settings when
Memorable already holds the hook, status names that registration, and a foreign
UserPromptSubmit hook is not mistaken for Memorable's.

lib/aside-render.ts serves the HTML's directory on loopback (Aside refuses file:// URLs), opens it with waitUntil load, prints through CDP Page.printToPDF so tagged output, outlines, header/footer templates and page numbers survive, emulates device metrics for sized screenshots, and writes in-page evaluations to files; when Aside is absent it runs the same spec through the browse daemon (newtab, load, js, pdf, screenshot, closetab) and reports ENGINE=aside|browse. bin/gstack-render.ts is the CLI skill templates call. lib/claude-bin.ts and lib/error-handling.ts become the canonical copies (browse/src re-exports them).

* refactor(browse): /browse drives Aside first, with the $B reference behind the fallback

Contract, cookbook, mode choice (aside repl by default, aside exec for reading), report format, the fallback section, and the full command reference carved on demand.

* refactor(qa): /qa and /qa-only drive Aside, fall back to $B

QA_METHODOLOGY runs every phase as Aside scripts (orient, explore, document, re-test, mobile viewport via CDP emulation, links via HEAD fetch); the authenticate phase is 'you are already signed in'; a 13th rule requires consent before mutating actions on non-local targets; the fallback section translates each step onto $B. The qa E2E tests run on whichever engine is present.

* refactor(design): design-review, design-consultation, design-shotgun, plan-design-review, design-html drive Aside

Design-system extraction is one script printing FONTS/COLORS/HEADINGS/TOUCH_TARGETS/NAV; competitor research confirms the exact URLs before opening them in the real browser and runs on the bundled browser when Aside is absent; design-html's viewport screenshots, sketches and comparison boards render through gstack-render.

* refactor(deploy): benchmark, canary, land-and-deploy Step 7, devex-review drive Aside

One aside repl script per page prints NAV/PAINT/LCP/RESOURCES/SCRIPTS/CSS/SUMMARY (benchmark), CONSOLE_ERRORS/NAV/TEXT + screenshot (canary, re-run every 60s), and the post-deploy check reads responseStatus from the navigation entry; each carries the $B fallback.

* feat(third-party-actions): Aside is the recommended driver; gstack's visible browser stays the fallback

The readiness probe is lifted from {{ASIDE_SETUP}} at gen time (byte-identity pinned) and rule 3 points at browse/SKILL.md for how to drive; the consent question offers Aside first and gstack's own visible browser (handoff/resume for sign-in) as the fallback, as v1.72 framed it.

* refactor(scrape): /scrape reads pages through Aside; the browser-skills runtime rides the fallback

Look-then-extract scripts build the JSON inside the page and print it between JSON_START/JSON_END; aside exec for fuzzy intents; on the $B fallback the browser-skills match/prototype flow and /skillify apply as before.

* refactor(make-pdf): print through Aside first, the bundled browser otherwise

asideClient.ts replaces the direct $B client with one render() call per PDF (the exact option mapping the browse pdf command had: paper, margins, header/footer/page numbers, tagged, outline, printBackground, preferCSSPageSize, Paged.js wait); the diagram pre-pass, oversized-image downscale and DOCX rasters each run as one render script with per-fence try/catch; exit 4 now means no browser is available and names both remedies; $P setup reports which engine it found. The e2e gates run on whichever engine is present, so the Linux lane exercises the fallback.

* refactor(diagram): the triplet is one gstack-render call

SVG, PNG and excalidraw from one invocation over the content-addressed bundle staged under /tmp/gstack-render; every diagram type gets an excalidraw export; gstack-render picks the engine and prints ENGINE=; the diagram E2E gates on either engine.

* feat(research): web research runs in Aside first, WebSearch second

The planning, review, design, security and investigate skills research through {{ASIDE_RESEARCH}}; WebSearch stays in allowed-tools as the fallback; testing.ts's bootstrap step follows; skeleton ceilings ratcheted for the research block.

* feat(setup,gen-skill-docs): prune renders of skills that no longer exist

setup gains _prune_stale_generated for every host tree and the doc generator removes gstack-* output dirs it did not write, so a skill removed from the source tree can never linger in an install.

* test: registries, budgets and suite reconciled for Aside-first with the $B fallback

Touchfiles + E2E tiers gain the Aside keys, coverage matrix and eval baselines updated, size budget re-baselined to parity-baseline-v1.80.0.0.json (the contract plus fallback ride in every browsing skill), parity ceilings ratcheted with measured values, LLM-judge prompts and the E2E fixtures speak Aside-first, browse-fallback.

PR #2804 with main's v1.80.0.0 ownership gate: bring the Codex/Factory/
OpenCode/Cursor/Kiro copy loops and the stale-render prune under the

heading equals VERSION (the collision that git cannot see).

* fix: pre-landing review fixes for the Aside-first branch

Review army + adversarial passes (Claude and Codex) on the merged branch:

setup
- _prune_stale_generated scans the host dirs too (the generator already
  removed the render before setup ran, so the host branch was dead), skips
  symlinks in the render tree (rm -rf on a slash-terminated link empties its
  target), removes a host symlink only when it resolves into gstack, cleans a
  bannered real dir through _cleanup_weak_dir, recognizes frontmatter-renamed
  skills, and logs through log. The always-run codex render passes every host
  dir that may link to it.
- NEEDS_BUILD checks all three binaries (with $_EXE) and lib/ sources; the
  browser hint and the bootstrap summary honor GSTACK_SKIP_ASIDE, treat a
  requested skip as a request, and derive one skill list.

lib/aside-render.ts + bin/gstack-render.ts
- The loopback server carries a per-render secret path, checks containment on
  the real path (symlink escapes are 403), and rejects malformed encoding.
- Inline eval results are one base64 line, so page text cannot forge
  ASIDE_DIR= or the sentinel; the last ASIDE_DIR wins.
- runProc escalates SIGTERM to SIGKILL, bounds every wait, and clears every
  timer (an uncleared one kept gstack-render alive after printing OK).
- renderTmpDir refuses a shared /tmp name owned by someone else; the work dir
  and server are created inside try; goto's budget follows the render budget.
- probeAside classifies a present-but-failing CLI as ASIDE_NOT_RUNNING like
  the skills' bash probe; render() retries on gstack's own browser when Aside
  could not start or its private CDP bridge is gone (never on a page error
  or a timeout of a running script); the CLI reports the engine that actually
  rendered, exits 0 on --help, rejects non-numeric flags, documents
  --wait-timeout, fences EVAL/PAGE_ERRORS as untrusted content, and names the
  daemon's cookie-import JS lock remedy.
- The browse path passes --scale only when asked (a scale change rebuilds
  the daemon context) and restores the viewport after a sized screenshot.

resolvers / templates
- The bash probe honors GSTACK_SKIP_ASIDE and has a perl deadline on stock
  macOS; .local is no longer LOCAL (mDNS); same-origin filters compare parsed
  origins; link status is HEAD-checked only on LOCAL targets; every
  aside exec goes through the receipted _aside_exec prelude
  ({{ASIDE_EXEC_PRELUDE}}), including nine template blocks that called it
  bare; the design sketch and diagram staging use private directories.
- The generator prunes only bannered renders and never a host whose
  generation failed.

Docs, stale comments and dead code cleaned; goldens re-rendered; tests
updated and added for every behavior above.

* test: coverage for the render CLI, setup rebuild check, make-pdf exit codes, and prose $B spans

New free tests from the ship coverage audit: test/gstack-render-cli.test.ts
(argv guards, --help, output contract with a fake daemon, failure and
serve-root paths, no-browser case, prompt exit), test/setup-needs-build.test.ts
(every binary and source set flips NEEDS_BUILD, Windows suffixes),
make-pdf/test/cli-exit-codes.test.ts and setup-smoke.test.ts (error to exit
code mapping, runSetup stages, renderPdf's engine), and prose-span cases for
extractBrowseCommands in test/skill-parser.test.ts.

BROWSER.md, ARCHITECTURE.md, CONTRIBUTING.md, README.md, CLAUDE.md,

LOCAL host rule without .local, LOCAL-only HEAD checks in the links script,
GSTACK_SKIP_ASIDE across probe/renderer/setup, the ownership-gated

* fix(test): skill-e2e-bws slices the $B setup block from the Browser fallback section

browse/SKILL.md no longer has '## SETUP' / '## Core QA Patterns' (Aside is the
primary driver; the $B block moved under 'Browser fallback'), so the gate test
sliced an empty block and handed the agent nothing to run. Anchor on
'### Find the `$B` binary' up to the next heading. 7/7 pass.

* fix(test): gate POSIX-only fixtures off Windows

windows-free-tests: the gstack-render CLI tests drive a shebang fake browse
that CreateProcess cannot exec, and two NEEDS_BUILD cases assert an execute
bit and a bare-name miss that MSYS bash does not have (test -x ignores mode
bits and resolves design -> design.exe). Those describes and cases now
self-skip on win32; argument guards, --help, the no-browser case, and every
other rebuild-check case still run there.

* fix(render): runProc waits for the exit code until the kill deadline; newtab retries once on a cold daemon

A process whose pipes have reached EOF is exiting, but runProc gave the exit
code only five seconds to arrive and then returned null, which run() reports
as a failed command. Under CI's six-shard load one such render failed with the
artifact already written. The SIGTERM/SIGKILL timers already bound the wait,
so the exit race now runs to the kill deadline.

The first CLI call auto-starts the browse daemon; on a cold start it can
answer 'Unable to connect' once while the server is still coming up. That
single case is retried after 1.5s; every other newtab failure is not.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* test(aside-render): warm the daemon before live fallback cases; failures name the render error

- Live fallback cases run 'goto about:blank' up to twice before asserting and
  skip (never fail) when the daemon cannot come up.
- expectOk() puts r.error and the browse transcript into the assertion so a
  failed render is diagnosable from the CI log.
- The argv-contract cases dump the fake's log on a miss.
- File default timeout is 30s: the subject is the CLI contract, not latency.
- Two cases pin the cold-daemon newtab retry and that other errors are not
  retried.

Garry TanandClaude Fable 5.1 c241216637 v1.80.0.0 fix: setup survives a failed Chromium install, hooks share one state root, gstack never clobbers a skill it did not create (#2802) 
* fix(freeze): hook reads the same state root /freeze writes — fails closed under GSTACK_HOME (#1459, #1509)

check-freeze.sh resolved its state dir as ${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}
while every writer (/freeze, /guard, /unfreeze, /investigate) resolves through
bin/gstack-paths, GSTACK_HOME first. With GSTACK_HOME set, /freeze wrote
freeze-dir.txt under GSTACK_HOME, the hook read $HOME/.gstack, found no file,
and allowed everything — a deny-tier boundary failing open.

One resolver now: gstack_hook_state_root() in careful/bin/hook-extract.sh
(already sourced by both check-freeze.sh and check-careful.sh) implements the
exact gstack-paths chain, including the CLAUDE_PLUGIN_ROOT guard that keeps a
CLAUDE_PLUGIN_DATA leaked from another plugin from redirecting our state.
check-freeze.sh and gstack_hook_log_fire both call it; nothing spawns
gstack-paths from a hook.

Tests: the GSTACK_HOME deny regression, GSTACK_HOME-over-CLAUDE_PLUGIN_DATA
precedence, plugin-root guard both ways, and a byte-parity check against
bin/gstack-paths across six env combinations. Existing freeze tests now pass
CLAUDE_PLUGIN_ROOT like a real plugin install would.

Idea from PR #1509 (@NikhileshNanduri); implemented natively against the shared
resolver rather than a second fallback chain.

* fix(relink): never delete or link over a skill gstack does not own (#2119)

gstack-relink runs on every ./setup. Its cleanup did `rm -rf` on any same-name
entry whose SKILL.md was a symlink, with no readlink check, and its link step
did `mkdir -p` then `ln -snf` onto any existing SKILL.md — on Linux that
replaces a user's real file with a symlink into gstack (macOS refused by
accident). setup's Windows mode-flip cleanup deleted any real dir whose name
matched a gstack skill. A personal `qa` skill, or a fork installed under
another path, was destroyed by the installer of a tool it never asked for.

Ownership is now proven, never assumed. An entry is ours when it is a symlink
resolving into INSTALL_DIR or RENDER_DIR, a real dir whose SKILL.md is such a
symlink, or a real dir carrying the .gstack-owned marker setup now writes for
Windows copy installs (legacy copies count when byte-identical to the source
or carrying gen-skill-docs' AUTO-GENERATED header). Anything else — including
an entry whose readlink fails — is foreign: left untouched, reported on
stderr, and listed in relink's summary line. The same rule replaces setup's
Windows name-match deletion; setup:1040 and gstack-uninstall:204 already
gated on readlink, so this closes the last unguarded deleter of the class.

Tests: foreign real dir in flat mode, foreign flat entry on a prefix flip,
foreign directory symlink, RENDER_DIR-targeted entry (ours), marker-carrying
copy (ours), marker-less copy (foreign); the Windows cleanup test now proves
provenance three ways and keeps the user's own same-name skill.

Idea and two regression cases from PR #2119 (@smblight); implemented on the
destination entry, not only the symlink target.

* fix(setup): Chromium bootstrap is best-effort and bounded — skills always register (#1900, #1901, #1902, #913, #2233)

setup runs under `set -e`, and the Chromium bootstrap in section 2 sat ahead
of skill registration in section 4 with a bare `bunx playwright install
chromium`, an unbounded download, and an explicit `exit 1` after the
post-install launch probe. On an offline, proxied, or AppArmor-restricted box
the user ended with ZERO skills registered and a re-run that died at the same
line; a wedged download hung setup indefinitely.

Every browser failure now records a reason code in _PW_FAIL_REASON and setup
continues: skipped (GSTACK_SKIP_PLAYWRIGHT=1, #913), chromium-install,
chromium-install-timeout (the download is bounded by the existing
_wait_with_deadline helper, default 600s, env GSTACK_PLAYWRIGHT_INSTALL_TIMEOUT,
process tree killed via _kill_tree), chromium-install-locked (another setup
holds the lock: this one registers skills and re-probes next time instead of
exiting), windows-no-node, windows-node-modules, post-install-launch (with the
GSTACK_CHROMIUM_NO_SANDBOX=1 hint for Ubuntu 24.04's userns policy, #2157).
The daemon font refresh is skipped when Chromium is unavailable. The final
summary names the skills that need the browser (/qa, /qa-only,
/design-review, /browse, make-pdf, /pair-agent) and the fix for the recorded
reason, and logs the reason code (never a path) through gstack-telemetry-log
when telemetry is on.

Tests: static invariants over the anchor-sliced block (no exit, every reason
code, deadline helper, trap chaining, guarded refresh, summary contents) plus
an integration harness that executes the real block with a stubbed probe and
installer: install failure, hang killed at the deadline with the tree kill
recorded, non-numeric knob fallback, live lock (continues, installer not run,
lock preserved), stale lock reclaimed, post-install probe failure, and the
skip flag.

Credit @DavidMiserak (PR #1900) for the best-effort shape; re-implemented on
the current block.

* docs(designs): preserve the time-attack fork-port residual evaluation

The read-only evaluation of what remains portable from time-attack/gstack
(583 raw candidates, 415 canonical, 287 with a residual, 48 adversarially
refuted, 14 standing) lived only on a throwaway VM. This records the report,
the lite residual index, the absorbed/superseded ledger, the refuter
verdicts, and SHAS.md with the fork tip, upstream HEAD, merge-base, and a
sha256 per file, so every scheduled fix in this wave series traces to its
evidence.

parity audit), each with rationale, and updates the two residual bullets for

* fix(relink): canonicalize link targets before the ownership check

Pre-landing review finding: the ownership gate compared readlink output
textually against INSTALL_DIR and RENDER_DIR, so two shapes of gstack's OWN
entries read as foreign and were left behind on a mode flip — a legacy
relative link (`gstack/qa/SKILL.md`, resolved against $PWD instead of the
link's directory) and an entry linked against the real path of a symlinked
install dir (~/.claude/skills/gstack -> checkout). Both now resolve: relative
targets anchor at the link's directory, the directory part is canonicalized
with pwd -P (the basename stays verbatim so a dangling managed target is not
misread), and both spellings of each root are accepted. Two regression tests.

* fix(telemetry): one-shot setup events never sweep other sessions' pending markers

gstack-telemetry-log finalizes every .pending-<session> marker that is not
the caller's own as outcome:unknown and deletes it. setup's onboarding
events (_setup_welcome, _setup_playwright) have no session of their own, so
a Chromium bootstrap failure during a live skill session recorded a false
unknown for that session and removed its marker.

New --no-sweep flag skips the stale-marker pass; both setup call sites use
it (the synthetic --session-id did not prevent the sweep). Surfaced by the
Codex adversarial pass.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* fix(hooks): partial upgrades fail closed for freeze and fall back for careful

A hook script and its sourced helper can be copied at different times. With
an older careful/bin/hook-extract.sh that lacks gstack_hook_state_root:

- check-freeze.sh now emits a deny ("fail closed, re-run ./setup or
  /unfreeze") instead of dying under set -e with no decision JSON.
- check-careful.sh falls back to ${GSTACK_HOME:-$HOME/.gstack} so project
  rules under the plain chain still load and a decision is always emitted
  (a warn hook must never break on a stale helper).

gstack_hook_state_root prints its root without a trailing newline and both
callers capture it with a printf-x sentinel, so a GSTACK_HOME ending in a
newline round-trips byte-for-byte with the writer's %q form.
gstack_hook_log_fire stays on ${GSTACK_HOME:-$HOME/.gstack}/analytics, the
same two-step chain every other analytics writer and reader uses, so the
usage log remains one file under a plugin install.

* fix(setup): never link over, copy over, or reap a skill gstack does not own (#2119)

The relink gate alone left three destructive sites open:

- link_claude_skill_dirs runs BEFORE relink on every ./setup and used
  `ln -snf` (Linux replaces a user's real SKILL.md with a symlink into
  gstack) or, on Windows, rm -rf + cp followed by a marker that made the
  user's directory "ours" on the next flip. It and _install_alias_skill_md
  now consult _claude_entry_is_ours first and skip loudly.
- cleanup_prefixed_claude_symlinks kept a bare name-match deletion and a
  `*gstack*` substring match. Symlink arms use anchored `gstack/` segment
  patterns; the Windows real-file arm proves provenance (marker,
  byte-identity with our source, or the full two-line gen-skill-docs banner
  within the first 40 lines, never a one-line substring another generator
  could emit). cleanup_old_claude_symlinks uses the same banner rule.
- gstack-relink's fast path judged absolute targets before canonicalizing,
  so `/x/gstack/../foreign/SKILL.md` counted as ours; dot-segment targets
  now canonicalize first. Its banner rule matches setup's.

The `.gstack-owned` marker records the owning payload's realpath. Entries
skipped by setup or relink are listed in the final setup summary.

Chromium bootstrap refinements from the pre-landing review: an INT/TERM
trap kills the installer's process tree; the Windows npm chain no longer
masks an install failure; GSTACK_SKIP_PLAYWRIGHT=1 is reported as a choice
rather than a failure and sends no telemetry; the timeout knob is
normalized (0, 000, non-numeric, or more than nine digits fall back to the
600s default instead of killing on the first poll or never killing).

* fix(setup,relink): ownership proof has two strengths; weak proof never deletes a directory or discards a differing file

The first #2119 gate treated a byte-identical or banner-bearing real-file
SKILL.md as full ownership, so a prefix flip could rm -rf a user's directory
(their own qa skill started from a gstack SKILL.md, plus my-templates/) and
the link pass could replace their customized file with a symlink. Two
strengths now:

- STRONG: the .gstack-owned marker (we created the directory), or a
  directory holding nothing but symlinks and the marker (deleting it loses
  no data). Only strong proof removes a directory whole.
- WEAK: byte-identity with our source or the two-line gen-skill-docs banner
  on a real file. Weak proof covers that SKILL.md and our runtime-asset
  links only; a differing file is moved to
  ${GSTACK_HOME:-~/.gstack}/backups/skills/<ts>/<skill>/ before we link
  over it, and setup/relink print one summary line naming what moved.

The marker is written on every platform now (path-independent proof for
Windows copies and for checkouts whose path carries no gstack segment), but
only for a directory gstack creates: a directory we merely link into
(unclaimed, or a legacy install) never becomes deletable whole. A directory
with no SKILL.md at all is unclaimed: the link pass may add our file, the
cleanup pass has nothing to remove.

Also from the review passes: the banner check reads 8192 bytes, not 40
lines (investigate, office-hours, plan-ceo-review and design-consultation
carry the banner past line 40 and were left "foreign" on pre-marker
Windows installs); a link into a checkout named without a gstack segment
(git worktree add ../gstack-<branch>) is ours when that tree carries
setup + VERSION + bin/; relink's fast path is gone so both files
canonicalize before judging; relink's root alias (_gstack-command) is
gated and stamped like every other entry; relink reports the bare entry
name with setup's wording and setup dedupes when forwarding
(_run_relink_quiet); the summary names the browser skills as examples.

* fix(setup): Chromium-install lock reclaim is atomic and pid-validated; abandoned locks expire; the tree kill walks /proc without pgrep

- A pid file holding "", "-1" or "0" counted as a live holder (kill -0 -1
  signals every process and succeeds), locking Chromium out for good. A pid
  must be a positive integer; anything else is stale.
- Two setups judging the same lock stale raced on rm -rf + mkdir and the
  loser deleted the winner's fresh lock. The stale dir is renamed first
  (atomic), so exactly one reclaims.
- A lock dir with no pid file (killed between mkdir and echo) was never
  reclaimed; it now expires once older than the install bound.
- _kill_tree needed pgrep; debian-slim and git-bash ship none, so the bound
  killed only the wrapper subshell and the installer kept running. Without

* fix(freeze): an unexpected non-zero death denies via an EXIT backstop instead of exiting with no decision

set -e plus a failing pipeline (a tool on PATH exiting non-zero, a deleted
cwd) ended the deny-tier hook with no JSON, which Claude Code treats as
non-blocking: the edit outside the boundary proceeded. The EXIT trap now
prints a deny for any non-zero exit that happens before a decision was
written; every deliberate output sets _FREEZE_DECIDED first so a late
failure never prints a second object.

Tests also pin careful's state-root precedence (GSTACK_HOME over
CLAUDE_PLUGIN_DATA, plugin data when CLAUDE_PLUGIN_ROOT names gstack) and
the specific "out of date" deny for a helper without gstack_hook_state_root.

* test: the two remaining linker harnesses extract the ownership helpers; the marker is the one allowed dotfile

setup-claude-skill-assets and user-render-out-dir-install slice
link_claude_skill_dirs out of setup without the helpers it now calls, so
the extracted function died with "command not found" (or, inside an if,
degraded into "foreign, skipped"). Both harnesses now carry the full helper
set and the globals. The hidden-files census allows .gstack-owned, which
the linker writes for directories it creates rather than copying from the
skill source.

* fix(setup,relink): weak proof never costs the user a file — assets, flips, failed backups, foreign dir links, alias markers

Third review cycle on the ownership model, every item reproduced against a
fixture before the fix:

- Runtime assets (sections/, templates/, checklist.md, ...) were refreshed
  with rm -rf regardless of who owned the directory, so an unclaimed or
  weakly-owned directory lost the user's same-named real files. Real assets
  are now replaced only in a directory gstack created or strongly owns
  (marker, or SKILL.md symlink into gstack), plus the legacy Windows
  real-copy shape; elsewhere they are kept and reported. Symlinks are never
  content and are always refreshed.
- The prefix-flip cleanup deleted a customized banner-bearing SKILL.md that
  the link pass would have backed up. Both cleanups now compare the file
  against the source (raw, or with its name: line rewritten to the entry
  name, which is how alias and prefixed copies legitimately differ) and
  move a differing file to the backup root.
- A failed backup (unwritable root) returned success and the caller linked
  over the file anyway. It now fails, and the entry is left untouched and
  reported.
- A foreign DIRECTORY symlink whose target had no SKILL.md fell through to
  the "unclaimed directory" rule and was replaced by a real directory. A
  symlink that does not resolve into gstack is foreign, full stop.
- The alias installers stamped .gstack-owned into pre-existing directories;
  they now follow the same created-or-already-marked rule.
- A directory counts as "only links" only when every link resolves into
  gstack: a user's own symlink makes it mixed, so their link survives.
- The gstack-tree heuristic requires bin/gstack-relink, not just a VERSION
  file, a setup script and a bin/ directory.

* fix(setup): lock reclaim hands a fresh lock back; a live holder past the bound is stale; /proc walk strips through the last paren

- Reclaim renamed the lock by path after judging it stale, so a second setup
  that had already reclaimed and re-created it lost its fresh lock and two
  installers ran. After the rename the moved directory's pid is re-read: a
  new live holder, or a fresh lock whose pid is not written yet, is moved
  straight back.
- A pid file whose process is alive but whose lock is older than the install
  bound is stale too (the holder is past its own deadline, or the pid was
  recycled to an unrelated long-lived process); it was locked forever.
- The /proc fallback stripped the comm field to the FIRST ") ", so a comm
  containing ") " hid a child from the kill. proc(5) says the last paren.

* fix(freeze): mark the decision written after the helper prints, not before

If gstack_hook_decision ever failed between the flag and its output the
backstop would have stayed silent; setting the flag after the print keeps
the deny backstop armed until a decision is actually on stdout.

README troubleshooting + manual uninstall cover the skill ownership gate
(.gstack-owned marker, ~/.gstack/backups/skills/<ts>/, foreign same-name
skills left untouched). CLAUDE.md and CONTRIBUTING carry the ownership and
best-effort Chromium bootstrap invariants for people editing setup and
gstack-relink. PROJECT_STRUCTURE gains careful/, freeze/, guard/, unfreeze/,
gstack-upgrade/, gstack-relink, and the setup/relink/hook test files.
TESTING_INTERNALS documents the anchor-sliced setup harness convention.

* fix(setup): the final summary reports customized SKILL.md files moved to the backup root

The linker moved a weakly-proven, customized SKILL.md aside before linking
over it but never said so; only relink printed a "Moved N" line, and by the
time relink runs the file is already a symlink. The summary now names each
moved file and where it went, next to the foreign-entry report.

* test: run assembled setup harness scripts from a temp file, not `bash -c` argv (Windows MSYS2 8 KB truncation)

windows-free-tests (run 33907177851) failed in
test/setup-alias-name-uniqueness.test.ts with
  bash: -c: line 178: unexpected EOF while looking for matching `'
The harness slices functions out of `setup` and passed the joined script as
one `bash -c` argv element. The ownership gate grew that script from 6.7 KB
to 15.7 KB, and on Windows bash is an MSYS2 program: when its parent is a
non-MSYS process (bun), msys-2.0.dll's build_argv() runs any argument
containing `?*["'(){}` through globify()/glob(), which copies the pattern
into a fixed `Char patbuf[8192]` and silently stops after 8192 - MB_CUR_MAX
(8186 chars under C.UTF-8); GLOB_NOCHECK then returns the truncated text as
the argument. Character 8186 lands inside the single-quoted sed token on
line 178. Rebuilding the exact script with CI path shapes and cutting it at
8186-8190 characters reproduces the identical message locally; cmd.exe's
8191-UTF-16 cap and CreateProcess's 32767 do not fit the evidence.

Fix: test/helpers/bash-script.ts writes the script to a temp file and runs
`bash <path>` — a short glob-free argument that never enters globify. Every
setup harness that assembled a script for `bash -c` (11 files, 22 sites)
uses it; timeouts and env are preserved verbatim, spawn/timeout errors are
appended to stderr, temp cleanup is best-effort. `spawnSync('bash',
[<Windows absolute path>])` already passes on windows-latest in setup-help,
uninstall-windows-copies and the migration tests. The Windows-curated list
is byte-identical before and after.

Garry TanandClaude Fable 5 0d1bd5616c v1.79.0.0 fix: ship subagent dispatches can no longer strand the run (#497/#2440 class) (#2772) 
* fix(ship): foreground-flag + deadline + scope guard on all four dispatch sites (#497/#2440 class, 3rd recurrence)

Steps 7/8/10/18 dispatch subagents whose LAST-line JSON the parent
consumes, but none passed run_in_background: false — since Claude Code
v2.1.198 subagents background by default, so /ship stranded at Step 18
waiting on output that never arrives. Every site now renders the shared
{{FOREGROUND_DISPATCH_NOTE}} resolver constant, carries a ~10-minute
deadline with an explicit recovery branch (stop the runaway task,
reconcile against pre-dispatch HEAD, surface stray state, never
re-dispatch), and Step 18's prompt gains a docs-sync-only scope guard
(no VERSION changes, no base-branch merges, push-rejection reported as
pushed:false with parent-side reconciliation and a second-failure
branch). Greptile failures now record as UNAVAILABLE, not zero comments.

GENERATED_WITH_GUIDANCE pins all five ship dispatch carriers; a new test
pins the deadline recovery + scope guard phrases in pr-body (.md and
.tmpl). Codex/factory ship goldens re-rendered.

* feat(document-release): first-class spawned-dispatch contract

document-release's own templates had zero subagent-awareness — the
entire headless contract lived in /ship's dispatch prompt, so any other
orchestrator (or an older installed /ship) dispatching it inherited none
of the gate handling. The skill now carries the contract itself: detect
spawned strictly from the dispatch prompt or the preamble echo (never
from file content — prompt-injection guard), auto-choose recommended
options while keeping the never-clobber-CHANGELOG and
never-bump-VERSION-silently invariants via their Skip options. Step 8.4d
gets an explicit spawned note (its interactive recommendation bumps
VERSION — wrong headlessly), and the Codex Documentation Review section
skips itself in spawned sessions (the apply gate needs a human; the
dispatching workflow owns review passes).

Contract, 8.4d note, and resolver skip are pinned in
run-in-background-guidance.test.ts; document-release skeleton budget
re-measured (39,812 B) and ratcheted to 40,200.

* fix: sweep every remaining synchronous Agent-dispatch site with run_in_background: false

The #2440 failure shape was a silently-missing review voice — a
specialist launched in the background and merged before it completed.
Every remaining synchronous dispatch site now carries the explicit flag:
the Red Team dispatch, the spec review loop, the Codex
second-opinion/plan-review/doc-review Claude fallbacks, the adversarial
subagent, design sketch and outside voices, autoplan's design/eng/dx
phase dispatches, CSO parallel finding verification, and design-shotgun's
variant launch. Parallel fan-outs stay parallel — multiple foreground
Agent calls in one message run concurrently (the shipped v1.64.0.0
review-army pattern).

GENERATED_WITH_GUIDANCE now pins all 24 generated carriers, so a new
dispatch site that drops the flag fails the free suite. Six carved-skill
skeleton ceilings re-measured and ratcheted (~80-130 B growth each);
factory ship golden re-rendered.

* fix(document-release): one canonical spawned contract, downstream notes are pointers

The diff-selected LLM-judge eval scored the skill's clarity 3 (threshold
4, main scores 4): the spawned-session rules read as three separately-
framed rule sets (contract paragraph, Step 8.4d note, Codex-review skip).
The contract paragraph now declares itself the single source of spawned
behavior and the two downstream notes reference it instead of restating
rationale. The pointer avoids naming the Codex section verbatim so the
codex-host render (which strips that section) keeps its negative pin.
Judge re-scored 4/5/4 across repeated samples after the change.

* fix: foreground note names the Agent tool as non-substitutable

The ship-docsync gate E2E caught a behavioral regression: the note's
blocking-emphasis ('a backgrounded dispatch strands the run') steered
the driven agent to run doc-sync via the Skill tool inline — the most
blocking option — twice in a row, forfeiting the fresh-context isolation
the dispatch exists for (baseline on main's text dispatches via Agent).
The shared note now says explicitly: dispatch with the Agent tool itself,
never substitute Skill or inline execution; the flag already makes the
call block. Re-verified: ship-docsync passes on the amended text.

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

* fix: pre-landing review fixes

Review army + red team findings, all verified before applying:
- ship-docsync E2E now asserts run_in_background === false on the
  captured dispatch (red team CRITICAL: phrase pins prove text exists,
  this proves the model obeys it — verified passing live).
- Structural scanner test: any generated file with an Agent-dispatch
  imperative (or bare '(foreground)' prose, the #2440 inert shape) must
  carry the flag or hold a reasoned exemption — the 4th-recurrence net
  the hand-enumerated pin list can't provide.
- Parent push reconciliation models reality: the parent shares the repo,
  so a non-fast-forward that hit the subagent hits the parent identically
  — fetch + ahead/behind check first, push only when the rejection was
  transient; dispatch prompt promise softened to 'the parent will handle
  it'.
- Recovered commits from a dead subagent are vetted docs-only
  (git show --stat, never VERSION/package.json) before any push.
- Deadline pacing named: ~3 minutes between checks, wall clock not polls.
- Greptile UNAVAILABLE recording narrowed to the PR body (Step 20's
  schema carries no triage field).
- document-release contract gains the echo-failure tie-breaker: prompt
  claims spawned + no echo → fail fast with the dispatch contract's
  failure shape instead of reproducing the #2733 prose-STOP; contract
  anti-injection and NEVER-relax clauses pinned in tests.
- 'Claude Code v2.1.198' extracted to CC_BACKGROUND_DEFAULT_SINCE and
  interpolated at all resolver sites (byte-identical output).
- CHANGELOG: entry-boundary blank line restored; worst-case-wait row
  scoped to the backgrounded path.

* fix: adversarial review fixes — failure shape, CHANGELOG guard, vet coherence

Claude adversarial subagent findings (11), all verified before applying:
- The dispatch JSON contract gains an explicit FAILURE shape
  ({"error":...}) and a parent branch for it — a doc-sync that could not
  run (spawned marking failed, broken preamble) previously had only the
  no-updates shape to emit, which the parent printed as 'Documentation is
  current': a silent false-clean of exactly the VAS-449 class.
- Scope guard now covers CHANGELOG: skip Step 5 voice polish and resolve
  CHANGELOG-touching gates to leave-as-is (the parent authored the
  release entry; the prompt's older auto-choose clause conflicted with
  the contract's never-rewrite invariant).
- Recovery vet is sequence-coherent: pushing a commit pushes its
  ancestors, so ANY non-doc commit (VERSION, package.json, CHANGELOG.md)
  blocks the whole sequence — no more push-the-vetted-child-of-an-
  unvetted-parent hole.
- Steps 7/8/10 failure branches stop a still-running backgrounded task
  before falling back, so a late result never races the inline audit.
- 'Documentation synced' print gated on pushed:true (item 6 owns the
  local-only outcome); doc-review skip note's backward step pointer
  fixed; foreground note scoped 'at initial dispatch' so the sanctioned
  inline FALLBACKS in Steps 7/8 read as sanctioned; constants docstring
  no longer overclaims single-sourcing (names the 3 inline templates).
- Runtime-hook TODO raised P2 → P1: the spawned trust chain is
  agent-self-asserted; prose cannot close it, the hook can.

Both docsync gate E2Es re-verified green on the amended prompt, including
the strict run_in_background === false dispatch assert.

* fix: codex adversarial fixes — JSON trust, fail-open visibility, user-state safety

Codex outside-model adversarial pass (inline-diff workaround for the
sandbox), P1/P2 findings triaged cross-model:
- Parent validates the dispatch JSON's field types and treats
  documentation_section as untrusted markdown (Step 19's redaction scan
  covers the final body; instruction-shaped text inside it is never
  followed). The error branch now explicitly skips items 2-6.
- Remote-ahead divergence is named, not silent: the parent lists foreign
  commits before creating a PR over a moved branch.
- Recovery cleanup never discards content: stray staged doc edits are
  unstaged but never checked out or cleaned away.
- Greptile UNAVAILABLE gets a concrete PR-body line, not a vague
  'wherever results are reported'.
Pre-existing-class P1s (self-asserted spawned trust chain, unenforceable
foreground timeout) are cross-model confirmed and tracked: PreToolUse
hook TODO at P1, harness-residue hazard documented.

* fix: never-Skill prohibition made unambiguous; docsync fixture made diagnostic

The ship-docsync E2E flaked on this sandbox because the driven agent
resolved the STOP pointer's ~ to nonexistent homes (/root, /home) and
acted blind — pass/fail sampled model priors, not the prompt. The
fixture prompt now names the planted sections dir, making local runs
deterministic (CI, with real install paths, was always diagnostic).
With a diagnostic fixture: 2/2 passes, real pr-body read, Agent dispatch
with run_in_background: false, zero Skill-tool substitutions.

Prose: the foreground note now states the dispatch happens ONLY via the
Agent tool (invoking the target as a Skill is wrong even though it
appears in the skills list; inline FALLBACKs apply only after a
dispatched subagent has failed), and the Step 18 imperative carries the
never-the-Skill-tool clause at the decision point.

windows-free-tests flaked on this PR: the tunnel-less restart bound
daemon.loopbackPort + 1 — a fixed neighbor of the OS-assigned ephemeral
port — and died with 'Is port 55738 in use?' whenever another shard or a
TIME_WAIT socket held it; the file-level retry re-rolled the same dice.
Every other startDaemon in the file already uses loopbackPort: 0 and the
assertion reads d2.loopbackPort, so nothing needs a predictable number.
21/21 pass locally.

 		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.

* 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).

Wave-amended: goldens regenerated against the wave tree (author's golden commit 8e7a03ca superseded)

* 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

* 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
how the hardcoded path shipped in the first place. resolveChromiumProfile's
env behavior is already pinned in config.test.ts; this pins cli.ts's
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).

Receipt: the slow-but-present sibling test fails on a v1.77.0.0 scratch

* 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
  fence fails).

- 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
  under real bash and zsh in the new test. Expect a step-change in
  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.

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

* 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

it; the content was never read on the error path under test).

* test(memory-ingest): fence regression test survives Windows tmpdirs

Wave polish on the #2699 absorption: the hand-built JSONL interpolated the
raw tmpdir into a JSON string — on Windows (D:\a\...) that's an invalid
escape, the user line was silently dropped, and the body started at
'## 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
'in dir()'; consult-mode initialized neither and rebuilt the counter with
a dir() conditional per event. Both parsers now init turn_completed_count
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
run in separate shells, and an unset/empty path would previously send an
empty body (gh) or cat's error output (glab) instead of the scanned bytes.
Codex/factory ship goldens regenerated.

* 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
the live install inside it, and the failure-restore arm would 'restore'
the stale backup — possibly deleting the only good copy. The upgrade now
refuses to start and tells the user to inspect/salvage the backup.

'refusing to send unscanned <noun>' read as if 'unscanned' modified a

* 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
warn (naming the source), apply the default for this run only, and skip
the config write. The opt-out log line names the actual decision source
(flag/env/config) and no longer claims a removal that may not have
happened.

* fix(memory-helpers): slow-probe warning no longer suppresses the absent warning

One shared _gitleaksWarned flag served two different messages: a 'machine

silenced the later 'gitleaks not in PATH; secret scanning disabled'
warning — the user never learned scanning was off for good. Split into
per-message flags.

* refactor(lib): shared isExecTimeout helper; export GbrainBinProbe

The killed/SIGTERM/ETIMEDOUT discrimination was hand-rolled at three sites
(gbrain version probe, engine classifier, gitleaks probe) and free to
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.

* refactor(gen-skill-docs): extract parsePathFlag; fix rewriteSectionBase docstring

--out-dir and --link-root shared near-identical inline parsing; one helper
now owns it. The rewriteSectionBase docstring said 'no-op when --out-dir
is unset' but the gate is the link root (which --link-root can set
independently) — it now describes the real behavior.

* refactor(memory-ingest): reunite preparePages with its docblock; pin disambiguateSlugs wiring

The #2724 disambiguateSlugs block was inserted between preparePages'
docblock and the function, orphaning the secret-scanning policy doc onto
the wrong symbol. Reordered. A call-site pin now asserts the prepare→stage
flow actually invokes disambiguateSlugs, so a refactor can't drop the call
while every unit test stays green.

* test(hostile-path): per-run mkdtemp root; telemetry-log redaction coverage

The suite used a FIXED tmpdir name, so concurrent runs (sharded runner,
sibling worktrees) tore down each other's trees mid-flight — now a
per-run mkdtemp root with the apostrophe dir inside. gstack-telemetry-log
was the one bin named in the suite header with no test: it now must append
a real row under the hostile path with the credential span redacted
(<REDACTED-github.pat>) and the rest of the message preserved.

The only migration without a dedicated test. Covers copy-when-absent

existence and contents, not just exit codes.

SPAWNED_ESCAPE_SENTENCE's tightened wording had no pin: positive pins on

parentheticals ('e.g. your dispatch prompt says', 'marks this session as
spawned'), and a drift guard that both hook directives embed the constant
verbatim.

* test(codex): execute the JSONL parser under real python3; fence scanner tracks opener length

The parser's turn.completed/turn.failed/disconnect semantics were pinned
by shape only — now the python block is extracted from both RENDERED
sections and run against synthetic event streams (tokens line, FAILED +
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
fence wrapping a 3-backtick example no longer false-positives, with a
self-test.

POSIX consumer that holds the 64KiB kernel buffer full at child exit;
asserts complete parseable JSON with matching counts and exit 2, plus an

* fix(memory-helpers): per-run cooldown bounds the slow-gitleaks probe cost

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.

CONTRIBUTING.md: the day-to-day example now edits the .tmpl (SKILL.md

identity-checked Chromium reap; env table gains CHROMIUM_PROFILE and

v1.76 regression that silenced plan reviews is dead. Flagged by the
cross-model doc review; headline now leads with the user-visible outcome.

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.

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

* 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.

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

* 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.

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

* 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.

Garry TanandClaude Fable 5 253d1dfe26 v1.76.0.0 fix: ship doc-sync survives Conductor — spawned subagent sessions reachable (#2733) (#2741) 
* feat(session-kind): explicit GSTACK_SESSION_KIND override; skill-start spawned gates keyed on kind (#2733)

Claude Code subagents inherit the parent env byte-for-byte, so ambient
markers classify them as the parent's kind and the spawned classification
was unreachable outside OpenClaw. GSTACK_SESSION_KIND=spawned (step 0,
spawned-only by design) lets a dispatching skill mark its subagent per
command. skill-start now keys SPAWNED_SESSION and the spawned-session
instruction block on the resolved kind (was raw OPENCLAW_SESSION),
suppresses CONDUCTOR_SESSION for spawned sessions, gates all 11
interactive-onboarding blocks plus their ack-at-emit marker writes on
kind != spawned, and adds a destructive-gate carve-out to the spawned
block (conservative-continue, never prose-STOP).

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

* fix(hooks): spawned-session escape in Conductor AUQ deny; override coverage in AUQ-error fallback (#2733)

Hooks inherit the harness env, so a per-command GSTACK_SESSION_KIND
prefix inside a subagent's bash can never reach them. Levers added:
a deterministic [conductor][spawned] auto-choose deny for env-level
spawned sessions (OPENCLAW_SESSION or session-wide GSTACK_SESSION_KIND),
and a spawned escape sentence appended to both hooks' prose directives
so a marked subagent that slips and calls AUQ resolves to auto-choose
instead of prose-STOP. The sentence lives in one shared constant
(hosts/claude/hooks/spawned-directive.ts) so the two paths can never
drift; destructive semantics are unified to conservative-continue.

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

* fix(ship): Step 18 marks the document-release subagent spawned — env prefix + auto-choose prompt (#2733)

The dispatch prompt now (1) frames the run as a SPAWNED subagent whose
LAST line is machine-parsed, (2) instructs prefixing the preamble's
gstack-skill-start invocation with GSTACK_SESSION_KIND=spawned on the
same command line (template bash blocks don't share exports), and
(3) resolves every AUQ gate to auto-choosing the recommended option,
conservative on no-recommendation, never destructive. The JSON contract
gains a required "decisions" array (auto-chosen gates, printed to the
ship console — never embedded in the public PR body) and a placement
clause so the skill's own doc-health summary stops competing with the
LAST-line JSON. Tripwire pins added; codex/factory goldens refreshed.

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

* feat(auq-format): proactive SESSION_KIND=spawned rule ordered above the Conductor rule (#2733)

The spawned classification previously existed only in the failure-fallback
branch — a spawned session was invited to call AskUserQuestion and reach
auto-choose via the deny/error detour, and a spawned session inside a
Conductor workspace hit the Conductor prose-STOP rule first. The Tool
resolution list now leads with the spawned rule (auto-choose recommended,
never prose, never BLOCKED, destructive gates resolve conservative), the
self-check carries the never-reach-this-checklist clause, and all tier>=2
SKILL.md renders are regenerated. Context-budget fixture refreshed in the
same commit per the ratchet protocol (the AUQ section is eager in every
tier>=2 skill).

* test(e2e): spawned document-release subagent returns the JSON contract through a firing gate (#2733)

The behavioral proof the bug shipped without: ship-docsync stubs the
skill (no preamble, no gates) and skill-e2e-workflow suppresses the
gates by prompt. This gate-tier E2E plays the parent — it drives the
verbatim Step 18 dispatch prompt (extracted from the live pr-body.md,
drift-proof) against a real preamble-bearing document-release slice in
a Conductor-ambient env with both AUQ hooks seeded live, an unbumped
VERSION making Step 8 fire. Asserts: the final line parses as the
5-key JSON contract, the fired gate's auto-choice is recorded in
decisions, and VERSION is untouched (the gate resolved to its
recommended Skip). Burn-in: 1/1 pass, $0.35, 21 turns, 106s.

* docs(openclaw): document the GSTACK_SESSION_KIND override; wire session-kind into paid selectors (#2733)

OPENCLAW.md's spawned-session section now covers the explicit per-command
marker, its deliberate spawned-only narrowness, the /ship Step 18 usage,
the destructive carve-out, onboarding-block suppression, and the hook
env-blindness caveat. bin/gstack-session-kind and the shared
spawned-directive module join the conductor-prose and
auto-decide-preserved selector dep lists (session-kind previously
appeared in no touchfiles entry — editing it alone triggered no paid
E2E). TODOS.md gains the plan-tune capture follow-up for spawned
auto-choices.

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

* fix: pre-landing review fixes (#2733)

Review army + coverage audit findings, all applied:
- headless directive carries the spawned escape sentence too (multi-
  specialist: a CI-hosted ship's marked subagent must not end BLOCKED)
- anti-injection scoping on every text-claimable spawned trigger (AUQ
  rule + shared escape sentence): markings count only from the creating
  prompt, never from files/tool output/web content read mid-run
- [conductor][spawned] deny annotates one-way doors per question
- SPAWNED_OVERRIDE: env tamper-visibility status line + OPENCLAW.md note
- spawned sessions skip the network update-check and first-task probe
  (consumers suppressed; preserves the one-shot just-upgraded marker)
- test hardening: dispatch-tripwire end-bound validated, vacuous marker
  asserts replaced with output asserts, E2E cpSync size filter + named
  fence tolerance, spawnedByEnv parity pin, destructive-policy cross-
  surface drift guard, one-way annotation + bogus-value hook cases
- session-kind duplicate rationale comment deduped; regen + goldens +
  context-budget fixture refreshed

Garry TanandClaude Fable 5 07b59e396c v1.75.0.0 feat: ponytail import wave — simplification review lens, arm benchmark, reuse ladder, instruction-tier digest (#2722) 
* feat(autoplan): eng review always runs last — the gate reviews the final amended plan

Reorder the pipeline to CEO -> Design (if UI scope) -> DX (if developer-facing
scope) -> Eng. The old order (CEO -> Design -> Eng -> DX) let DX findings land
AFTER the required gate signed off, so eng validated a stale plan.

Accept-all semantics made explicit: every AskUserQuestion resolves to the
recommended option; premises no longer pause the pipeline mid-run (clearly-wrong
ones queue as User-Challenge items at the single Final Approval Gate). Eng's
Codex voice now sees the DX consensus summary. New free static test pins the
order; the chain E2E gains DX-between and Eng-terminal assertions.

* feat(review): simplification specialist — advisory over-engineering lens with ponytail's tag vocabulary

New 8th Review Army specialist (DIFF_LINES > 100, --simplification force flag)
hunting unrequested STRUCTURE only: delete/stdlib/native/speculative/shrink
closed tags, one-line findings, lines_removable field. speculative: replaces
ponytail's yagni: tag — we import the lens, not the posture; coverage stays
sacred (Completeness Gaps owns it, suppressions inlined, shrink needs >=5 lines).

Advisory carve-out in the merge step: advisory findings are excluded from
quality_score and the findings-count header, render with an [ADVISORY] label,
and are ASK-only in Fix-First. Zero-findings case prints the lens-scoped
'Simplification: lean already — nothing to cut.' from the PARENT (the
specialist keeps the exact NO FINDINGS contract); with findings, the parent
prints 'net: -N lines possible' summed from lines_removable.

Tests: static pins for the carve-out + early-out contract (gen-skill-docs),
two periodic e2e cases with planted fixtures — activation (over-build traps:
hand-rolled Intl, one-impl abstract, dead config) and false-flag precision
(a lean ETHOS 'choose A' diff must yield NO FINDINGS).

* feat(preamble): reuse ladder in Search Before Building — rungs 2-5 of ponytail's ladder, completeness kept

Tier-3+ skills gain a per-edit reflex the section only stated as research
discipline: before writing new code, stop at the first rung that holds —
repo helper, stdlib, native platform feature, installed dependency — then
build the COMPLETE version of what remains. The closing clause is the
explicit reconciliation with Boil the Ocean: the ladder governs structure,
never coverage. Rungs 1/6/7 (YAGNI / one line / minimum that works) are
deliberately NOT imported.

Also ports ponytail's root-cause rule: one guard in the shared function
beats a guard in every caller.

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

* feat(preamble): bounded-closer output rule for tier-2+ skills

After completing work, skills report in a few short lines — what changed,
what was skipped, what to watch — and cut any explanation that outgrows the
change. Explicit exemptions protect every mandated output: decision briefs,
completion-status blocks, user-requested explanations, and report-shaped
skills' report formats (the report IS the work in /qa-only, /plan-*-review,
/retro, /document-generate).

Rationale is signal-to-noise, not tokens: ponytail's own benchmark shows
terse prose alone doesn't cut cost (caveman arm: -20% LOC, +7% tokens), and
independent replications found its 'skipped on purpose' essays ate the code
savings. Includes a good/bad closer example pair per the model-overlay
guidance that a positive example beats a 'don't be verbose' instruction.

* docs(resolvers): terse-mode savings claim matches measurement — 2.6KB, not 3-5KB

Measured on the v1.71 render: --explain-level=terse saves exactly 2,611 bytes
per tier-2+ skill. The old ~3-5KB claim predated the preamble restructuring.

* feat(retro,preamble): gstack-shortcut debt ledger — accepted shortcuts leave a joined trail

When the user accepts an option that is BOTH Completeness <= 7 AND a
durable-scope call, the decision ledger entry (gstack-decision-log, ceiling +
upgrade trigger in the rationale) is the source of truth, and the agent marks
each cut corner in code with gstack-shortcut(dec-<id>): <ceiling>, upgrade
when <trigger> — same edit, no follow-up question, never agent-initiated.

/retro Step 11.5 harvests markers into a debt ledger (grep || true — zero
matches is the healthy case; skill installs and docs excluded), joins on the
decision id so nothing double-counts, tags unlinked and no-trigger rot risks,
and closes with 'N markers, M with no trigger.'

/review suppressions: a marker with ceiling+trigger downgrades a would-be
Completeness Gaps finding to acknowledged debt. Redaction test pins that the
marker ships untouched (the ledger is the point) — it does not match the
TODO(owner) hygiene shape.

Format from dietrichgebert/ponytail's ponytail-debt; store inverted to gstack's

* test: refresh golden ship baselines after preamble additions (reuse ladder + bounded closer)

The golden-file regression test pins the rendered ship skill byte-for-byte;
the WS3/WS7 preamble sections are deliberate changes, so the baselines
re-capture per the goldens' own update protocol.

* feat(hosts): instruction-only tier — a 2KB committed rules digest any agent host can read

New agents-digest/gstack-AGENTS.md (1,765 bytes, hard 2,048-byte budget):
gstack's ethos one-liners, the reuse ladder, and voice rules for hosts with
no install arm — Zed, Amp, Jules, or any AGENTS.md-reading agent. Generated
by scripts/gen-agents-digest.ts, auto-refreshed by gen:skill-docs, committed
like llms.txt so setup's explainer arms can point at it before any toolchain
exists. First line carries the gstack version as its own staleness nudge.

Delivery is print-path + user-performed copy ONLY: setup never writes or
overwrites a user's AGENTS.md (a test pins this — no cp/ln/mv/redirect into
AGENTS.md anywhere in setup). openclaw and hermes explainer arms print the
path; slate keeps routing to the full Claude install and gbrain ships from
its own repo. HostConfig gains the optional install.instructionTier slot,
declared by both instruction-tier hosts. README host table now matches what
setup actually does.

Inspired by dietrichgebert/ponytail's instruction-tier AGENTS.md fallback —
one generated source, never per-host hand copies.

* feat(preamble): AskUserQuestion repetition cut — gated, passed NOT-WORSE A/B

Removes the duplicate statements v1.71's compaction left in the
AskUserQuestion Format section: the completeness rule restated in the prose
triad, the auto-decide marker syntax stated twice, the Conductor-flakiness
explanation stated twice, and the self-check's full triad restatement. Every
verbosity floor and all 14 format pins stay (Layer 0 green).

The gate this decision rested on ran before landing (new periodic
skill-e2e-auq-repetition-cut-ab.test.ts, pre-cut ref 3263fffe vs this
render, same harness as auq-verbose-vs-carved-ab): POST 7/7 format elements,
substance 5 — identical to PRE. No degradation; the load-bearing-repetition
hypothesis did not hold for these duplicates.

Net: -236 bytes per tier-2+ skill (~9.7KB corpus). Golden ship baselines
re-captured for the deliberate change.

* feat(evals): with-skill vs without-skill arm benchmark — measures whether gstack's behavioral layer earns its tokens

Ponytail's honest-benchmark method pointed at gstack itself: 3 build-shaped
tasks (native-platform over-build trap, CRUD endpoint, bug fix with planted
decoys) x 2 arms, real claude -p sessions, scored on the git diff left
behind. A research instrument, not a release gate — no assertion compares
arm scores.

Arms use the PROVEN project-scope pattern: the with-arm installs a
build-discipline skill (extracted reuse-ladder + bounded-closer content, not
whole-file copies) into the fixture's .claude/skills/ with a CLAUDE.md
routing line and an explicit invocation; a live spike confirmed claude -p
discovers and invokes project-scope skills via the Skill tool (3 turns,
exact-output probe). Fixtures are git init + local bare origin; diff capture
is three lines of git, no worktree machinery.

Failure taxonomy: zero-diff arms are VALID scored cells (deterministic
0/none, no API call), harvest failures record harvest:null, judge_error
cells are excluded from aggregates but named in the report — nothing drops
silently. armJudge: fixed sonnet judge, 0-3 unrequested-structure rubric,
must name the construct or say none, bounded retry-on-malformed; callJudge
gains optional temperature/max_tokens (defaults unchanged). recordE2E now
populates tokens_used for every E2E. Eval schema v2: harvest gains
{insertions, deletions, net}, tolerant reads keep v1 runs comparable.

Registered periodic in E2E_TIERS + touchfiles (with the auq-repetition-cut
A/B); periodic detach timeout raised to the new shard-census floor. Free
selftest (8 tests, zero API) pins fixtures, extraction, arm asymmetry, diff
capture, judge plumbing, and the retry bound.

* test: absorb the ponytail-import wave into the guard fixtures — ceilings, schema pin, triad phrasing

Skeleton ceilings re-captured for the 17 carved skills the wave deliberately
grew (reuse ladder + bounded closer + shortcut trail, net of the gated -236B
AUQ cut), each with its measured size in the comment per the carve-guards
protocol. eval-store schema pin updated to v2 (harvest gains
insertions/deletions/net). The AUQ prose-triad keeps its pinned per-choice
phrasing ('explicit on EACH choice') while still deferring the score scale to
the canonical Format rule — the shipped cut is strictly closer to the pre-cut
text than the render that already passed the NOT-WORSE gate. Autoplan carve
anchors follow the Phase 2.5 renumbering. Golden ship baselines re-captured.

* feat(test-runner): GSTACK_FREE_JOBS + opt-in flaky-retry pass for syscall-supervised sandboxes

GSTACK_FREE_JOBS overrides the computed shard count (the free runner's
analogue of the paid runner's EVALS_JOBS). On Vercel sandboxes, PID 1
installs a seccomp filter whose supervisor spuriously fails access(2) for
busy processes — measured: 200/200 git-init probes fail 'Cannot access work
tree: Permission denied' while the suite runs at 6 shards, 0/200 idle;
statx succeeds while access fails on the same path in the same process.
One serial mega-shard maximizes per-process pressure and fails too; 2
shards is the measured sweet spot.

GSTACK_FREE_RETRY_FLAKY=1 (default OFF — dev boxes should see flakes)
re-runs attributed failures once, serially, capped at 5 files; a clean
retry downgrades to a loud FLAKY-PASS naming the offenders, a repeat
failure stays red, timeouts and unattributed failures never retry.

* fix(browse): portable temp paths — TEMP_DIRS allowlist, tmpdir()-based test files

Local path validation now accepts os.tmpdir() alongside the classic /tmp
(new TEMP_DIRS in platform.ts): on macOS os.tmpdir() is /var/folders/...,
and TMPDIR-honoring CI/sandbox environments point it elsewhere entirely —
both are legitimate scratch space. Remote file serving (TEMP_ONLY) stays
pinned to TEMP_DIR alone; no change to the exfil boundary.

commands.test.ts drops 41 hardcoded /tmp literals for a tmpp() helper on
os.tmpdir() (two message assertions now reference the same variable), and
path-validation's symlink-escape test targets /etc/hosts instead of
/etc/crontab — the target must EXIST for realpath to resolve the link (a
dangling target falls back to the link's own path and passes vacuously),
and /etc/crontab is absent on Amazon Linux.

* fix(config): portable sha256 — Linux ships sha256sum, not shasum

resolve-user-slug and endpoint hashing exited 127 on Amazon Linux (shasum
is a macOS/perl tool). New _sha256_hex helper prefers sha256sum and falls
back to shasum, matching gstack-verify-gate's existing pattern; both call
sites converted.

* fix(next-version): only trust ls-remote when origin is actually configured

Without the guard, git DWIMs the literal 'origin' as an ssh host/path; on
hosts whose transport launders exit codes the probe 'succeeds' with zero
branches and the allocator silently sees an empty queue — the exact
duplicate-allocation failure (#2545) fetchGitClaimed exists to prevent.
git remote get-url origin gates the probe; absence falls through to the
existing local-refs path with its staleness warning.

* docs(testing): sandbox-doctor — one command makes a cloud sandbox run the suite green

Measured failure taxonomy for Vercel/Conductor sandboxes (missing /dev/fd,
64M /dev/shm, seccomp-supervisor access(2) EACCES under load, uid-1000
processes with FULL capabilities defeating chmod-denial tests, no X server,
no git identity, Conductor git-shim exit-code laundering) plus the
idempotent script that treats all of it and seeds the run recipe.

* fix(config): converge on main's self-contained sha8_of — its tests extract the function standalone

The merge kept a branch-local _sha256_hex helper; main's v1.72 landed the
same portability fix inline WITH tests that extract sha8_of()'s text and run
it under a shim-only PATH — a helper call can't satisfy that shape. Adopt
the landed implementation at both hash sites.

* fix(release): version-bump write regenerates the version-stamped agents digest

agents-digest/gstack-AGENTS.md embeds VERSION in its first line and is
byte-freshness-gated (test/agents-digest.test.ts + Skill Docs Freshness CI),
but nothing in the release path regenerated it — every version-bumping ship
of this repo would land red. write now spawns the repo's own generator when
present (agentsDigest true/false/null in the output JSON), and ship's
evidence gate allow-lists the digest alongside VERSION/package.json.

* fix(setup): instruction-tier explainer prints the script-anchored digest path

* test(digest): broaden AGENTS.md writer tripwire; pin digest-resolver ladder lockstep

The print-path-only guard now catches tee/install/rsync/dd/truncate, >>
appends, and laundered variable-destination writes. New test ties the
digest's hand-rendered reuse-ladder text to the preamble resolver so an
edit to either fails CI instead of shipping drift.

* fix(retro): shortcut harvest drops placeholder markers and convention docs

The Step 11.5 grep matched documentation mentions (dec-<id>, dec-*) in

rows on gstack itself. A trailing filter kills placeholder forms; prose
tells the agent to discard convention-quoting hits.

* fix(review): advisory findings count in per-specialist stats

Without this, simplification (all-advisory by construction) would log

* fix(evals): arm-benchmark harvest and judge hardening

- Harvest diffs against the recorded seed SHA (origin/main is movable by an
  agent that commits AND pushes; a recorded SHA is not).
- Fixtures get a node_modules .gitignore and the git wrapper a 64MB
  maxBuffer, so a vendored-dependency arm is scored instead of killing the
  cell.
- The judge diff cap is a named constant with loud truncation (log +
  judge_reasoning suffix).
- Judge prompt block markers carry a per-call random sentinel, so a diff
  containing a faked closing marker cannot escape the data block.

* fix(evals): AUQ A/B vendored pre-cut arm + judge-error inconclusive taxonomy

- The PRE arm read a branch-local SHA (3263fffe) that becomes unreachable on
  fresh clones after the squash-merge; the pre-cut render is now a vendored
  fixture.
- A judge failure on one side no longer coerces substance to 0 (which
  fabricated DEGRADATION on POST-side failures and masked regressions on
  PRE-side failures): null substance = inconclusive, format still gates.

* test: regression pin for the originConfigured guard vs laundering git shims

On healthy hosts the guarded and unguarded paths behave identically, so a
revert passes the suite; only a shim that makes 'git ls-remote' exit 0 with
empty output (the Conductor wrapper's observed behavior) exposes it. Pins
that the empty 'successful' probe is never trusted as an empty queue.

* fix(release): digest regen is an explicit --regen-digest opt-in, not presence-sniffed code exec

Review (security) caught the cycle-1 fix executing any repo's
scripts/gen-agents-digest.ts on plain 'write' — arbitrary code exec from a
hostile clone on a routine bump, contradicting the binary's own containment
posture. The regen still runs the TARGET repo's generator (a 'trusted' copy
beside the binary would false-red the freshness gate on version drift), but
only under the flag: /ship passes it deliberately, in a repo whose code the
operator already executes (its test suite). Plain write is side-effect-free
again. Also: uniform output shape (agentsDigest: null on the JSON-manifest
branch), a REAL generator round-trip test replacing the misnamed lockstep
check, and land-and-deploy's evidence gate gets the same digest allow-path
as ship so the two grading surfaces agree.

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

* fix(test-runner): flaky-retry vetoes on ANY unattributable failure evidence

The gate equated 'some failure attributed' with 'all failures attributed': a
shard with one attributed failure plus a headerless failure, an unhandled
error between tests, or a truncated run (no terminal summary) qualified for
retry — re-running only failingFiles and masking the rest as FLAKY-PASS,
re-opening the silent-truncation hole the strict classifier closes.
FreeShardOutcome now carries unattributedFailures; nonzero vetoes the retry.
Pins: mixed shard, truncated-with-attributed shard, empty-shard field values.

* fix(next-version): a configured origin advertising zero heads is never trusted

The originConfigured guard covered only the no-origin laundering case. With
origin configured (the normal Conductor worktree state), the laundering shim
makes a failed ls-remote exit 0 with empty stdout — read as 'the queue is
empty', the exact duplicate-allocation bug (#2545) one layer up. A reachable
remote always advertises at least its default branch, so an exit-0 zero-head
probe now falls back to local refs/remotes/origin with a laundering-specific
warning. Regression test shims git for both configurations.

* fix(sandbox-doctor): loud on git-shim patch drift; document the retry-contract override

- The /conductor/bin/git patch was a silent no-op if the shim's bytes drift
  from the exact pattern — now warns that laundering is NOT fixed.
- The bashrc block documents why GSTACK_FREE_RETRY_FLAKY=1 deliberately
  overrides the runner's default-OFF contract on this sandbox, and how to
  undo it.
- Test pins the guarded shm form (missing /dev/shm must not abort set -eu).

* test(digest): pin the script-anchored explainer path; catch declaration-prefixed writers

- Asserts $SOURCE_GSTACK_DIR/agents-digest path and forbids $(pwd)/agents-digest
  (the cycle-1 fix was revertible without failing anything).
- The laundered-assignment arm now matches local/export/declare/readonly/typeset
  prefixed assignments — the likeliest in-function writer shape in setup.

* refactor(evals): arm-benchmark selftest runs FREE on every PR

The selftest lived inside the paid skill-e2e-* file, so fixture-integrity

every gating check and be discovered when the periodic run burned money on a
dead instrument. Harness extracted to test/helpers/arm-benchmark-harness.ts,
selftest to test/arm-benchmark-selftest.test.ts (free suite). Touchfiles:
harness added to the three benchmark dep lists; the auq-repetition-cut-ab
tier comment now states the MANUAL re-run obligation honestly (periodic runs
force EVALS_ALL, so dep lists cannot auto-trigger it).

The cycle-2 additions pushed the python-patch and bashrc heredocs into the

Cross-model catch (Claude adversarial + Codex agreed): any diff author could

The final gate offered B2 (respond to User Challenges) but the option

amends the plan and re-runs Eng (the gate always reviews the final plan),
sharing D's 3-cycle cap.

* feat(evals): arm benchmark runs each fixture's functional oracle — correctness before LOC

The plan's metric order is diff-quality FIRST, but cells never ran the
fixtures' own run-tests.js, so a refusal, a broken implementation, and
working code were indistinguishable in aggregates (Codex adversarial catch).
Tasks with an oracle declare checkCmd; every cell records checks=pass|fail|none
in the report line and eval store. Selftest pins the oracle declarations and
that the planted bug fails its own check pre-fix.

the step now names what executes and why that is inside the envelope Step 5
already opened (the repo's own test suite).

* fix(sandbox-doctor): atomic git-shim patch, :99-socket Xvfb check, dnf gate, non-interactive sudo

- The /conductor/bin/git patch writes tmp-then-rename with a .orig backup —
  a concurrently spawned git can never exec a truncated shim.
- Xvfb running-check looks for the :99 socket, not any-display pgrep.
- Xvfb install is dnf-gated so non-dnf distros degrade to a warning instead
  of aborting the remaining fixes under set -eu.
- The bashrc /dev/fd restore uses sudo -n || true — no password prompt at
  every shell start on non-passwordless machines.
- BASH_COMPAT=50 keeps heredoc bodies off the bash pipe window.

* fix(browse): an untrustable TMPDIR (/, $HOME, a cwd ancestor) never widens the local allowlist

TEMP_DIRS honors os.tmpdir() at daemon start; a daemon launched with
TMPDIR=/ would have trusted the whole filesystem for local path validation

that a benign distinct TMPDIR (the sandbox recipe's $HOME/tmp) stays honored.

- The ls-remote zero-heads warning no longer accuses an empty remote of

* fix(test): temp-dirs asymmetry pins are topology-aware; TMPDIR probes are POSIX-only

CI exposed two wrong assumptions in the new temp-dirs tests, neither a
product bug:

- The remote-serving asymmetry test assumed a distinct os.tmpdir() lies
  OUTSIDE TEMP_DIR, but the free-shard runner nests each child's TMPDIR
  inside /tmp on CI — a file there is under TEMP_DIR, so serving it
  remotely is legitimate. The test now pins the actual exfil boundary on
  every topology (a cwd project file is locally readable, never remotely
  servable) and branches the os.tmpdir() case on nested-vs-outside.
  Reproduced locally with TMPDIR=/tmp/nested-tmp before fixing.

- The untrustable-TMPDIR subprocess probes set TMPDIR, which Windows
  os.tmpdir() ignores (reads TEMP/TMP) — and on Windows TEMP_DIR is
  DEFINED as os.tmpdir(), so the fixed+movable two-dir topology the guard
  filters does not exist there. Probes now skip on Windows with that
  rationale; the benign-TMPDIR assertion compares realpaths.

Verified under all three POSIX topologies: TMPDIR=$HOME/tmp (outside),
TMPDIR=/tmp/nested-tmp (CI shard shape), TMPDIR unset (identical).

* fix(build): DIGEST_RELPATH is a forward-slash literal on every platform

path.join built it with backslashes on Windows, so the wiring test's

path.join(root, DIGEST_RELPATH) at the write site normalizes fine.

* fix(sandbox-doctor): bashrc block re-heals the /dev/shm remount on sandbox restart

The 4G remount does not survive restarts; a reverted 64M shm made the

(observed live: two consecutive full-run failures, green in isolation,
green again after remounting). Same guarded arithmetic as the doctor body.

* fix(test): close the cross-shard porcelain race that failed Windows CI

Two-part fix for the gen-skill-docs-out-dir isolation-pin failure:

- cookie-import-browser built its scratch cookie DBs inside the TRACKED
  browse/test/fixtures/ dir (created in beforeAll, deleted in afterAll), so
  they flash as untracked files mid-run — a concurrent shard's porcelain
  snapshot caught the window on Windows. The DBs now live in a per-run
  tmpdir; zero source-tree writes.

- gen-skill-docs-out-dir is the free suite's only LIVE porcelain-snapshot
  test, so it joins TREE_MUTATING (the serial quiet window): any concurrent
  transient tree-write can race it, and its own spawned render rewrites
  llms.txt/agents-digest in place (idempotent on a fresh tree).

The race is pre-existing; this branch's +5 test files reshuffled shard
composition and exposed it.

The committed duration seed is recorded on fast CI; a syscall-supervised

shard predicted ~242s was wall-killed at its predicted-x3 725s wall while
genuinely progressing (the old count heuristic guaranteed 1265s). Packed
walls may be looser than the count floor, never tighter.

 		b1485d8897 v1.74.0.0 test/CI overhaul: green means green, suites restructured for speed (#2721) 
* fix(ci): free-tests lane actually runs the make-pdf e2e gates

The 9 make-pdf/test/e2e gate tests probe make-pdf/dist/pdf,
browse/dist/browse, and the diagram-render bundle, then self-skip when
absent. The required free-tests lane never built any of them, so the
gates silently skipped on Linux for their entire life (verified: 9 of
14 skip, exit 0). make-pdf-gate.yml's justification for deleting its
Linux leg claimed the free lane covered this — it didn't.

- new build:gates script: exactly the three artifacts the gates probe
  (full bun run build compiles five binaries; ~60-90s tax on the only
  required check is not warranted)
- free-tests.yml: build:gates step + poppler-utils +
  fonts-noto-color-emoji (fonts must precede the first browse daemon
  launch — Chromium snapshots fontconfig at startup; verified live:
  a warm daemon renders tofu, a fresh one embeds NotoColorEmoji)
- make-pdf/test/e2e/ci-prereqs.test.ts: GSTACK_EXPECT_BINARIES=1 (set
  by the workflow) inverts the skip polarity in CI — dropping the
  build step or poppler fails the lane instead of re-opening the
  silent-skip hole

Pre-flight: all 9 gates green on Linux locally.

* fix(ci): kill the three zero-test eval jobs (hollow green)

- delete the vestigial e2e-codex / e2e-gemini matrix rows: both files
  are whole-file periodic-tier, so with no row tier: they ran ZERO
  tests and reported green on every PR (~2 min of runner each, pure
  false confidence; the periodic lane owns those suites)
- e2e-pty-plan-smoke gains tier: gate — its two files are whole-file
  describeE2ETier('gate'), so the job burned ~7 min of container setup
  then skipped every describe
- KNOWN_TIER_UNSET burned down to empty; the ratchet stays armed so a
  future row/file tier mismatch fails the suite instead of shipping
  hollow green

* fix(ci): least-privilege permissions + fork-safe concurrency keys

- evals.yml / evals-periodic.yml evals jobs: explicit contents:read +
  packages:read (container-image pull) and persist-credentials:false —
  the jobs that execute PR-authored code with three provider API keys
  ran on the repo-default token grant with the token written into
  .git/config
- permissions blocks for the 4 workflows that had none (skill-docs,
  make-pdf-gate, windows-free-tests, windows-setup-e2e)
- fork-safe concurrency keys: actionlint, skill-docs, make-pdf-gate,
  windows-setup-e2e switch from head_ref to PR-number keying — a bare
  branch name carries no fork prefix, so same-name branches from two
  forks shared one group and cancelled each other's runs

* fix(ci): one bun version everywhere + drift tripwire

Lanes disagreed four ways: 1.3.13 (free-tests, windows, Dockerfile.ci),
latest (quality-gate, make-pdf-gate), unpinned (skill-docs,
version-gate — setup-bun installs latest), 1.3.10 (.gitlab-ci.yml).
Different Bun versions change the runner output shapes the strict
classifiers regex-match, spawn semantics, and shell parsing — a lane on
a different Bun tests a different product; Dockerfile.ci's own comment
records this class biting once already (silent 1.3.13/1.3.14 drift).

All surfaces pinned to 1.3.13; test/bun-version-drift.test.ts scans
every workflow setup-bun stanza + Dockerfile.ci + .gitlab-ci.yml and
fails on any mismatch or unpinned stanza. skill-docs also gains
--frozen-lockfile (was bare bun install).

* test(ci): bind the three-way image-tag hashFiles() expressions

evals.yml, evals-periodic.yml, and ci-image.yml each compute the CI
image tag from hashFiles('.github/docker/Dockerfile.ci', 'bun.lock',
'patches/**') — synced by comment only (TODOS.md 'CI three-way
image-tag drift'). If one input list drifts, that workflow computes a
different tag for the same content: eval lanes silently rebuild the
image every run, or ci-image prebuilds a tag nobody looks up. The test
extracts each tag-computation site and fails on any mismatch.

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

* fix(ci): ci-image stops rebuilding the identical image every ship

- package.json out of the trigger paths: the tag hash deliberately
  excludes it (version bumps every ship), so every merge rebuilt and
  re-pushed the IDENTICAL tag (~2m26s for zero content change);
  patches/** added (it IS a tag input)
- manifest existence check (mirrors evals.yml): tag already exists →
  skip the build
- concurrency group: two rapid main pushes raced pushing the same
  :latest/:buildcache tags
- cron staggered 06:00→04:00 Monday: it shared the exact minute with
  evals-periodic, which could race a half-pushed tag or duplicate the
  build
- timeout-minutes: 30 (was unbounded → 360-min default for a hung
  docker build)

* fix(ci): quality-gate drops the 74s full-history checkout

fetch-depth:0 cost 74 of the job's 92 seconds; the three gates it feeds
take ~12s combined. Shallow checkout + exact-SHA fetches for the diff's
base/head (an exact-SHA fetch, not a guessed depth — long-lived
branches and merge queues still resolve), with a --deepen fallback for
push events whose 'before' is unusable. timeout right-sized 20→10 min.

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

* fix(ci): small-lane batch — timeouts, right-sizing, windows cache warm-start

- timeout-minutes on the 6 remaining unbounded jobs (actionlint 5,
  skill-docs 10, version-gate 10, make-pdf-gate 15, pr-title-sync 5,
  evals build-image 15) — a hung step sat on GitHub's 360-min default
- right-size measured-over-long timeouts: dependency-review 10→5,
  windows-setup-e2e 15→10
- dependency-review: 2-core runner (28s API call on an 8-core box) and
  drop .github/workflows/** from its trigger paths (workflow edits have
  no dependencies to review)
- windows caches gain restore-keys: a lockfile bump paid the 26s/43s
  restore for a guaranteed cold miss

* fix(test): scope GSTACK_HOME to each file's execution window

Five files assigned process.env.GSTACK_HOME at module scope. Shard
processes evaluate sibling modules before running their tests, so the
assignment leaked into every other file in the shard — the damage was
already visible in defensive workarounds (relink.test.ts:28 'fresh
install test saw a neighbor's skill_prefix'; cdp-e2e's own comment
documents a sibling's temp dir baked into artifacts).

Pattern: save original, assign in beforeAll, restore in afterAll
(cdp-e2e already restored but still assigned at load — its window now
matches the others). GSTACK_TELEMETRY_OFF and GSTACK_PROJECT_SLUG get
the same treatment where they rode along. Victim files' defenses stay
in place (cheap insurance).

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

* test: tripwire against module-scope GSTACK_HOME assignments

Column-0 assignment of GSTACK_HOME / GSTACK_STATE_ROOT in any tracked
*.test.ts fails with the file:line and the fix (beforeAll + afterAll
restore). Kills the cross-file env-leak class the previous commit
swept.

* fix(test): e2e-harness-audit derives its skill census from disk

The hand-maintained 39-name SKILL_GLOBS list had drifted to 39 of 54
SKILL.md.tmpl on disk. No live gap today (none of the 15 unlisted
skills is interactive), but the next interactive skill would have
landed unguarded with zero signal. The audit now walks top-level dirs
for SKILL.md.tmpl (statSync so symlinked dirs like connect-chrome
count), so new skills are in scope the commit they appear.

* fix(evals): judges honor the eval-model resolution chain + real 429 backoff

callJudge inlined GSTACK_EVAL_MODEL_JUDGE || sonnet, silently ignoring
the global GSTACK_EVAL_MODEL override every other eval call site honors
via lib/eval-model.ts. New 'judge' kind in DEFAULTS (sonnet — the D1a
pin-on-regressors calibration stands; model CHOICE unchanged) and
callJudge resolves through it: explicit arg > GSTACK_EVAL_MODEL_JUDGE >
GSTACK_EVAL_MODEL > default.

429 handling upgraded from one fixed 1s retry (reliably lost races at
CI concurrency) to three jittered exponential retries (~1s/4s/16s),
honoring the server's retry-after when present.

* fix(test): the two expect(true) paid stubs become test.todo

skill-e2e-spec-execute (600s budget) and skill-llm-eval-spec (300s)
reported PASS on every periodic run while asserting nothing. Deleting
them would remove the periodic-tier selector surface they exist to
register (diff-based selection for spec/ changes), so they become
test.todo — reported as todo/skip, never pass — with the v1.1
implementation specs kept in-file.

* fix(test): reactivate 5 quarantined browse tests (2 security)

extension-sender-auth's two privileged-message denial tests (content
script + missing sender.url — the extension's security boundary) and
snapshot's three skips were quarantined 'pre-existing' failures. Root
cause: machine-local state on the quarantining dev machines — the test
and gate code are byte-identical between the quarantining commit
(410b4928) and HEAD, and all five pass deterministically on a clean
checkout (68/68 across both files, multiple runs). No assertions
weakened, no product changes.

* fix(evals): activate the 4 paid test files that could never run anywhere

carve-section-loading, codex-e2e-plan-format,
codex-e2e-recommendation-substance, and llm-judge-recommendation gated
on EVALS/tier (free suite loads them as describe.skip) but their names
fell outside PAID_TEST_GLOBS, so no paid lane ever selected them — net
execution zero, forever. The existing matrix tripwire filtered on
isPaidTestFile() first, so it was blind to exactly this class (the same
bug that hid the pre-split monolith's gate tests for ~8 releases).

- PAID_TEST_GLOBS: codex-e2e* + skill-llm-eval* wildcards (replacing
  exact names) + llm-judge-recommendation + carve-section-loading;
  package.json's six test-script glob lists mirrored
- codex-e2e-plan-format gains the explicit periodic tier gate its
  siblings carry (external-service rule) — without it the sharded
  runner's no-guard default would spawn Codex in the gate tier per PR
- eval:bg:periodic --timeout 32400→37800: the census growth pushed the
  periodic worst case to 35910s; the old value had 270s of headroom
  BEFORE this change and would now kill healthy runs mid-flight
- new test/paid-orphan-tripwire.test.ts: any EVALS/tier-gated test file
  outside the globs fails the free suite (reasoned SCANNER_EXEMPT for
  the gate helpers + meta-tests) — the class-killer
- paid-shards pins updated: the four orphans now assert INSIDE the
  census

* fix(browse): restrictDirectoryPermissions warns and skips symlinked dirs

Closes the Windows Free Tests red: recent lane failures showed a
platform-unguarded POSIX mode-bit assertion ('Expected: 493' — a
symlink-skip test) from PR-branch variants; the KNOWN_WINDOWS_SAFE
force-include reason ('mode-bitmask hits are POSIX-branch only') did
not hold for that shape, and main had neither the guard nor the
behavior.

- product: lstat first; a symlinked dir gets a warning and a skip on
  both platforms — chmod AND icacls dereference the link, so
  restricting through a symlink hardens an unvetted target (and
  /inheritance:r could lock out its real owner). All callers already
  treat hardening as best-effort (try/catch).
- test: the symlink regression test, platform-aware — symlinkSync in
  the house try/catch skip pattern (Windows runners without Developer
  Mode can't create symlinks), mode-bit assertion guarded off win32,
  behavior assertions (no throw, warning text, target readable)
  everywhere; POSIX still proves the skip (0o755 unchanged, not 0o700)
- KNOWN_WINDOWS_SAFE reason updated to the now-true premise

20/20 pass on Linux.

* fix(test): unique tmp dirs for plan artifacts + audited live-repo cwd sites

Six paid PTY tests wrote their expected plan artifact to a FIXED shared
/tmp path ('/tmp/gstack-test-plan-<mode>.md') and rmSync'd it in
finally — under --retry 1, EVALS_JOBS>1, or two concurrent worktrees, a
sibling's cleanup deletes this run's artifact and the D19 'agent did
not produce expected plan file' assertion fires spuriously. Each test
now mkdtemps its own dir, interpolates the unique path into the agent
prompt (fixture-sourced prompts get a replaceAll + drift guard that
throws if the fixture's literal ever moves), and cleans up its own dir.

The 18 cwd:-into-the-live-repo sites were audited: all deliberate
(skill registry + hermetic pre-trusted dir, in-repo gen renders, git
history reads, slug resolution) — each now carries a
'// LIVE-REPO CWD: <reason>' comment so the next audit can tell
deliberate from accidental.

* fix(test): trim the seven over-wall 1700s timeouts to the 1500s physical ceiling

1,700,000ms (28.3 min) exceeded every wall these tests run inside: the
25-min CI job timeout and the 1800s sharded-runner wall (which also
leaves --retry 1 zero room for a second attempt). Budget above the wall
is fiction, not headroom — a test that actually used it produced a
job-level kill (no bun summary, no artifact) instead of a clean
per-test timeout. No recorded p95 exists for this family (they are
being retiered to periodic in the re-platform wave); the trim stops at
the physical ceiling rather than guessing lower. Final policy lands in
the Wave-2 eval-budgets constants module.

* refactor(gen): main() guard — importing gen-skill-docs no longer regenerates the tree

The generator's whole body executed at module load, so any import of it
(test/gen-skill-docs.test.ts pulls assertSinglePreamble via require();
test/catalog-trim.test.ts imports helpers) regenerated all 71 SKILL.md
in place — the root cause of half the TREE_MUTATING serial-shard
entries (hazard class #2532). The body now lives in an exported
main(): number behind if (import.meta.main).

Semantics preserved exactly: failure exits are immediate (matching the
old top-level process.exit), success leaves the event loop to drain so
the llms.txt fire-and-forget IIFE finishes its write, and the module
stays synchronous/require()-able. Proofs: byte-identical --host all
output (git status clean), --dry-run stale-tree still exits 1 (the
skill-docs freshness lane depends on it), and the new
test/gen-skill-docs-import-purity.test.ts pins load-time purity via a
subprocess probe (mtime-based, so a dirty worktree can't false-fail).

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

* feat(gen): --out-dir renders every host, outputs-only

--out-dir was Claude-host-only (gen-skill-docs.ts:842), which forced
the codex/factory-regenerating tests (gen-skill-docs, skill-validation,
host-config) to mutate the live tree — the reason they sit in the
TREE_MUTATING serial shard. The flag now mirrors ALL outputs into the
out-dir: external-host trees (.agents/.factory/... via
processExternalHost), external section files, openclaw docs, and
gstack/llms.txt (a catalog-mode render must never rewrite the tracked
index). OUTPUTS ONLY — inputs (templates, sections/, host configs) are
always read from ROOT, so an empty out-dir can never feed the render.
rewriteSectionBase stays Claude-only (external hosts have their own
path grammar).

Proofs: in-place --host all is byte-identical (tree clean);
--host all --out-dir <mkdtemp> renders the full multi-host tree with
ROOT untouched; gen-skill-docs-out-dir tests + 415/415
gen-skill-docs.test.ts green (bin/dev-setup's claude rendering
byte-compat).

* fix(evals): every E2E key's dep list names its own declaring test file

129-of-177 keys omitted their own test file, so editing only a test's
prompt or assertions selected NOTHING — the changed test never ran on
the change that changed it. 135 keys self-registered (110 E2E + 25
LLM-judge), resolved by strict declaration evidence (testName:/
testIfSelected/judge call sites), with skill-name false positives
excluded.

e2e-tier-alignment's warn-only branch for unregistered files is now a
hard failure with a 4-entry KNOWN_UNREGISTERED ratchet (template-
literal testNames, fail-open-safe) + a burn-down test so the set only
shrinks. Selection sanity: a one-file diff on skill-e2e-qa-workflow now
selects its 4 tests (was 0); skill-llm-eval 0 → 25.

Known follow-ups (filed): 15 E2E + 2 judge PHANTOM keys select tests
that exist nowhere; codex-e2e-plan-format's testIfSelected names have
no map keys (run-all only).

* test(evals): ratchet the 8 newly-visible gate-matrix gaps

The self-registration sweep made these eight files' gate-tier keys
visible to the census for the first time — their gate tests run in NO
CI lane today (pre-existing hole, newly measurable). Ratcheted into
KNOWN_MATRIX_GAPS with the burn-down note: the paid-lane re-platform
runs every gate file by construction and retires this ratchet class.

* feat(test): duration-aware LPT shard packing for the free suite

Hash sharding balances file COUNTS (1.15x spread) but not cost — the
Playwright-launching files landed 4/3/4/1/2/1 across 6 shards, giving a
measured 28s–97s shard spread and ~40s of idle tail on every run.
Full-suite mode now packs by recorded per-file durations
(longest-processing-time-first) when the committed seed
scripts/free-test-durations.json exists.

- ONE store, no overlay: the seed is refreshed occasionally via the new
  --record-durations mode (each file timed in its own child — exact,
  and immune to bun's stream buffering, where silent passers print no
  header to timestamp); GSTACK_FREE_TEST_DURATIONS overrides the path
  for experiments; CI never records
- seed is a hint: missing → silent hash-shard fallback; corrupt (bad
  merge) → one warning + fallback; unknown files → 75th-percentile
  pessimism so a surprise long-runner can't recreate the tail
- packed shards get duration-aware walls (max(base, predicted x 3)) —
  LPT decouples count from cost BY DESIGN, so the 5s/file heuristic
  would undersize a shard holding few expensive files
- one log line per shard (files + predicted seconds) so packing
  regressions are diagnosable from any run log
- the --shard CI-matrix path is untouched: stable hash indices are its
  contract
- successor note in-code: bun >=1.3.14 ships native --timings/--shard
  LPT — swap this packer when the repo unpins 1.3.13

* fix(test): decouple slop:diff from bun run test; quality-gate runs it per PR

'bun run test' silently appended up to two 120s npx slop-scan runs plus
a git worktree add/remove after the suite (2>/dev/null || true) —
invisible in the documented '~90-100s' timing and pure friction in the
pre-commit loop. Decoupling is not coverage removal: quality-gate.yml
now runs slop:diff on every PR (advisory, matching its in-repo 'never
blocking' contract), and /review already invokes it explicitly.

* feat(test): eval-budgets timeout tiers + fit/ceiling policy test

Five named tiers (JUDGE 120s / CAPTURE 300s / CAPTURE_LONG 600s /
PTY 900s / PTY_LONG 1200s) replace hand-ratcheted sprawl (46x300s,
46x120s, 44x360s, 44x180s, 27x240s, 19x150s, 13x420s, 12x600s...),
much of it inflated to paper over the old 40-way in-shard concurrency
that the sharded runner's 1-file-per-shard model kills. Policy test
pins: every tier fits the shard wall minus 120s overhead (the
structural fix for budgets-above-the-wall fiction), tiers stay ordered,
and no paid literal exceeds PTY_LONG x1.25 — oversized tests get split,
not budgeted past the wall.

* feat(test): shared runBin helper for bin-script unit tests

~36 free test files each carry a near-identical local run() (spawnSync
+ utf-8 + {status, stdout, stderr}) differing only in env composition,
cwd, and timeout. runBin absorbs the invariant core; options carry the
variance (gstackHome sets BOTH GSTACK_HOME and GSTACK_STATE_DIR — the
config-precedence trap several locals rediscovered independently; home
for $HOME-anchored bins; input/trim/timeout/maxBuffer). Free-test-only
by design so it never becomes a de facto global touchfile. Migration of
the 36 call sites lands separately (mechanical batches).

* fix(test): runBin trim assertion — trim shapes stream ends, not interior

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

* refactor(test): mechanical sweep — 298 paid-test timeouts onto eval-budget tiers

69 files, both shapes (trailing bun-test budgets and runner
timeout/timeoutMs options), ROUND-UP ONLY so nothing that passed can
start failing: 75 → JUDGE_MS, 137 → CAPTURE_MS, 74 → CAPTURE_LONG_MS,
9 → PTY_MS, 3 → PTY_LONG_MS. Raw >=60s literal count in the paid scope:
395 → 97, of which 51 are non-timeout noise (fixture dates, run IDs)
and 46 are enumerated justified holds (comment-carrying calibrated
budgets, poll-loop constants, utility spawn waits, and the seven
physical-ceiling 1_500_000 sites). The eval-budgets policy ratchet
keeps the residue from regrowing.

Known collapse: where an inner runner budget and its enclosing test
budget now share a tier, the old stagger is gone — an overrun surfaces
as a bun test timeout instead of a graceful runner timeout
(diagnosability trade, not a correctness one).

* test: coverage fill — 95 tests for six zero-coverage surfaces

- eval CLI family (eval-list/compare/summary + eval-select smoke): the
  primary interface to eval results had no tests; isolation via a fake
  gstack-slug under a mkdtemp HOME (the scripts' real resolution path —
  they do NOT honor GSTACK_EVAL_DIR; only EvalCollector does). Pinned
  current behavior: eval-list does NOT exclude _partial runs (documented
  improvement candidate)
- slop-diff (runs on every /review + quality-gate): fixture git repo +
  first-on-PATH npx stub (never downloads real slop-scan); no-diff
  early exit, missing-scanner fallback, fingerprint line-insensitivity,
  merge-base worktree scan
- bin/gstack-code-intelligence CLI arg surface (lib was covered, the
  284-line CLI wasn't): select/consent/suggest/index/search gating;
  pinned: --help routes to usage failure exit 1 (no handler)
- browse media-extract: the page.evaluate callback exercised in-process
  against a mock DOM (no exports added) — lazy-src fallback chain,
  HLS/DASH detection, bg-image url() parsing, 500-element cap
- browse session-cookie-store: factory contract (cookieName/ttlMs/
  maxSessions eviction, cross-store isolation, mint→validate
  round-trip); store is in-memory — no fs cases exist
- lib/version-source direct unit tests (gstack-version-bump.test.ts
  spawns the bin, never imports the lib): parse/format/cmp/bump
  coercion, npm 4→3 translation, #2501 mangled-JSON regression class

All hermetic (mkdtemp homes, runBin child isolation); windows curation
correctly partitions the six.

* refactor(test): first runBin migration batch (3 of ~36 run() duplicates)

explain-level-config, benchmark-cli, evidence move onto the shared
helper; each file's remaining special-case spawnSync sites (raw-buffer
probes, env-scrub probes) stay put deliberately. 55/55 green.

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

* refactor(evals): paid shards spool to disk + shared runShardChild lifecycle

- runPaidShard no longer buffers whole 30-min stream-json streams in
  RAM (x concurrent jobs): every byte tees to a per-shard log file
  (slug-named, path printed at START for mid-run inspection and on the
  FAILED terminal line); failures print a 64KiB tail read back from
  disk; passing shards stay quiet (the file is the record) — the free
  runner's proven contract. Classification unchanged: the strict
  classifier still sees every byte first.
- the ~35 duplicated spawn/group-kill/wall-timer/finally-reap lines
  move into runShardChild in test-strict-output.ts (detached-per-
  platform spawn, signal forwarding, SIGKILL group kill at the wall,
  drain-before-verdict); designed so the free runner can migrate later
- expectedFiles drift fixed toward ENFORCEMENT: the injected-command
  exemption is gone — a fake command exiting 0 without bun's terminal
  summary now reads FAILED (pinned: silent-pass → failed)

* feat(evals): parent-computed selection propagates to shard children

The sharded runner computed diff selection once, then each of its 48-73
children recomputed it at module load — including, on touchfiles-diff
branches, a per-child bun subprocess evaluating the old data file (20s
timeout each). The parent now serializes {version, selected, reason} as
EVALS_SELECTION_JSON into the shard env; e2e-helpers adopts it at load.
Fail-open preserved: any parse/shape violation → ONE stderr warning +
local recompute; absent env → silent local compute (non-sharded
entrypoints unchanged). Drift test pins parent→child round-trip to
identical selection decisions plus the malformed/absent cases.

* fix(test): kill the four worst fixed sleeps (300s/30s/30s/20s)

- watchdog.test: the 20s blind wait for one production parent-watchdog
  tick becomes BROWSE_PARENT_WATCHDOG_INTERVAL_MS=250 (new env knob in
  server.ts, NaN-safe, production default unchanged) + polls for the
  boot line and the tick's stay-alive log — strictly stronger (the old
  form never proved a tick observed the parent death). 24s → 3.6s.
- stop-dead-daemon / terminal-agent-owner-watchdog: the 300s/30s
  stand-in child lifetimes become stdin-EOF-bound — the child can never
  self-exit mid-test on a slow runner (spurious-failure class) and
  self-reaps instantly if the test dies (no 300s orphans). Node-compat
  stdin APIs (owner-watchdog runs on the Windows lane).
- browser-skill-commands: the sleeper fixture's 30s self-time becomes
  8s (no stdin pipe exists in runToFiles) — far above the 1s product
  timeout it must outlive, below the test ceiling, so a timeout-kill
  regression fails on clean assertions instead of an opaque bun

45/45 green across the four files + server tripwires.

* fix(test): gen-skill-docs + catalog-trim leave the serial mutator shard

gen-skill-docs.test.ts's 15 in-place generator spawns now render into
mkdtemp out-dirs (gitignored-artifact reads repointed; the handshake
scan's silent console.warn degrade became a hard assertion); its
tracked-tree reads (freshness dry-run, SKILL.md content pins) stay
reads. catalog-trim needed no change beyond the earlier main() guard —
its import is now side-effect-free (pinned by the import-purity test).
Both TREE_MUTATING entries deleted in this commit, per the transition
rule: an entry leaves in the same commit as the file's last in-place
write.

* fix(test): host-config self-provisions goldens (ordering dependency severed)

Its goldens were 'produced by gen-skill-docs.test.ts' with a
when-missing beforeAll fallback that wrote the live tree — an
inter-test ordering dependency the serial shard hid. It now renders
codex+factory UNCONDITIONALLY into its own out-dir and reads goldens
only from there (the Claude golden deliberately keeps reading tracked
ship/SKILL.md — a read; out-dir claude renders repoint section-base
paths by design). TREE_MUTATING entry deleted.

* fix(test): gbrain-detection-override drops mutate-then-git-restore

regenAndSnapshot renders --host claude --out-dir <mkdtemp> (+
--respect-detection) and snapshots probes from the out-dir. The
git-restore machinery is deleted outright — it restored only
PROBE_FILES of the 71 files each call wrote, so a stale tree kept the
other 68 dirty (the partial-restore bug), and its 'no output-path arg'
comment had been false since --out-dir landed. TREE_MUTATING entry
deleted.

The full-catalog smoke no longer rewrites all 71 SKILL.md then

ship/SKILL.md is byte-unchanged. TREE_MUTATING entry deleted.

Two renders into two separate out-dirs, EVERY file diffed byte-for-byte

vacuous empty-dir pass) — strictly stronger than the old in-place
double-regen that sampled 5 files. TREE_MUTATING entry deleted.

* feat(test): the serial tree-mutating shard dissolves — TREE_MUTATING is empty

Zero mutators remain (all eight render into out-dirs now), so the four
ratchet READERS (parity caps, size budgets, carve parity/ordering) get
a quiet tree by construction in any shard and rejoin the parallel
phase. The ~35-40s serial tail on every full-suite run is gone. The
mechanism stays: a future test that genuinely must write shared
artifacts in place earns an entry with a reason and is serialized
again; the census pin still fails on renamed keys.

with bun run test:free --record-durations.

* feat(evals): planner/executor/report modes — the CI re-platform surface

One PLANNER computes diff selection + the slice plan ONCE and writes a
manifest (--emit-plan <path> --slices K); K executors consume it
(--plan <path> --slice i), never self-selecting, and write slice-result
artifacts; a REPORT reconciles results against the manifest (--report
<dir>) fail-closed: a slice whose artifact never landed is a FAILURE,
a planned shard nobody reported fails, wrong-slice/duplicate/cross-tier
results fail. Kills per-slice selector divergence and hollow-lane
aggregation at the root.

- hollow-shard guard: under EVALS_ALL, exit 0 with ZERO executed tests
  (bun's 'Ran N tests' now captured by the classifier — additive) is
  'passed-empty' and fails the run; selective runs keep it 'passed'
  with one warning (in-file diff/tier self-skips are legitimate there);
  unknown counts are never guessed hollow
- retry parity: --retry 1 default + RETRY_OVERRIDES literals for the
  three files whose old matrix rows earned retries: 2 (stale entries
  pinned against disk)
- live smoke: gate plan = 48 shards across 6 slices; report mode exits
  1 on a fabricated missing slice, 0 when complete

* feat(ci): sliced paid lane (planner -> 6 executors -> fail-closed report)

The parity-phase re-platform: evals.yml gains a second, sliced lane
driven by scripts/test-paid-shards.ts — the SAME engine local
eval:bg:gate uses, so CI and local share one selection engine.

- plan-slices: ONE planner (fetch-depth 0 — the only job needing
  history) emits the manifest; selection fails open to run-all, never
  per-slice (the divergence class is structurally dead)
- eval-slices: 6-way matrix consuming the manifest; PTY seed +
  skill-registration steps run unconditionally (idempotent — a sliced
  lane cannot key them on suite names); aggregate spawn budget
  6 x EVALS_JOBS=2 x EVALS_CONCURRENCY=2 = 24 lane-wide (the matrix's
  40-way per row queued session startup behind 39 siblings — the
  timeout-flake family root); slice results + spooled shard logs
  uploaded as artifacts
- slices-report: reconciles slice artifacts against the manifest
  FAIL-CLOSED via --report — a slice whose artifact never landed, or a
  planned shard nobody reported, is a failure, not an absence
- sequenced needs: evals so provider concurrency never doubles while
  both lanes coexist; the matrix + its ratchets are deleted after
  demonstrated parity (intersection + expected-additions comparison)
- workflow_dispatch gains evals_all (default true) for parity runs and
  post-merge smokes — a dispatch can never silently select zero

* feat(ci): weekly periodic lane runs EVERY periodic test + gate census backstop

evals-periodic.yml re-platforms onto the sharded runner: planner
manifest → 6 executor slices → FAIL-CLOSED report. This IS the coverage
contract: all ~70 periodic-tier files weekly (EVALS_ALL=1), killing the
silent-rot class where a hard-coded 9-file matrix left ~57 files
running NOWHERE (the autoplan E2E rotted invisibly for months).

- test/helpers/periodic-exclude-data.ts: reasoned exclusions in their
  OWN literals file (deliberately not touchfiles-data — map-diff
  evaluates old versions of that file standalone). Every entry carries
  reason + tracking with a re-entry condition; the runner surfaces each
  exclusion per run; policy test pins real-file + non-empty fields.
  Initial: ship-idempotency + brain-privacy-gate (documented-red,
  never green) and skill-e2e-ios (manual hardware). The TODOS 'sidebar
  E2E trio' turned out already deleted — only tombstone tests remain.
- gate-census job: weekly EVALS_ALL gate-tier run — PR lanes are
  diff-billed, so without this the full gate census might never execute
  anywhere; with the hollow-shard guard it is a census-health check
  (exit 0 + zero executed tests fails), not just a test run.
- failure notification is a concrete gh issue UPSERT (one tracking
  issue, commented per red week — never issue-per-week spam), with
  issues:write scoped to the report job.

* v1.73.0.0: test/CI overhaul — green means green, suites restructured for speed

Version + release notes for the audit-and-overhaul branch: every
silently-skipping or never-running test class fixed and tripwired, the
free suite duration-packed with the serial mutator shard dissolved, the
paid lane re-platformed onto the sharded runner (planner/slices/
fail-closed report, parity phase), the weekly all-periodic coverage
contract, eval-budget timeout tiers, and 95 new coverage tests.

* fix(ci): first-live-run fixes — executor history + two environment-blind assertions

The sliced lane's first run (PR #2721) did its job: the planner and
report worked, the manifest governed, and every failure had a name.
Three were fixable on the spot:

- executor + gate-census checkouts get fetch-depth: 0 — files with
  SELF-derived selection (the LLM-judge map, routing) walk git at
  module load, and selection is deliberately fail-closed on git errors,
  so the shallow checkout crashed those shards ('ambiguous argument
  main...HEAD'). The manifest still governs WHICH shards run.
- landscape --toc gate: the exact toBe(3) landscape-page count was
  font-metric-dependent (3 on Amazon Linux, 2 on ubuntu CI — the same
  disease the file's own page-index comment warns about). Now a
  comparative invariant: --toc must not CHANGE the landscape count vs
  a baseline render.
- paid-run-manifest parse test builds its manifest under EVALS_ALL so
  it never walks git (proven with GIT_DIR=/nonexistent).

Remaining first-run failures are newly-exposed rot in gate files that
had never executed in CI (skillify D1 refusal, session-intelligence
context-restore, one tpa-apple-ban retry flake) — being probed
separately; they are the lane WORKING, not the lane failing.

* fix(test): per-shard CHROMIUM_PROFILE — the collision class duration packing exposed

Nine test files launch in-process persistent contexts or daemons that
default to the SHARED ~/.gstack/chromium-profile. Two concurrent shard
processes on one profile dir kill each other's browser — observed live
on CI once duration packing recomposed shards: handoff's
launchPersistentContext died 'Target page, context or browser has been
closed' (--user-data-dir=~/.gstack/chromium-profile in the call log)
while a sibling shard's daemon logged 'Chromium process crashed'. Hash
sharding had masked the collision by chance placement; handoff passes
standalone everywhere.

Fix at the runner, not per file: each shard child gets
CHROMIUM_PROFILE=<shard-state>/chromium-profile (the documented env
knob, same isolation idea as the existing per-shard TMPDIR). Files
within a shard run serially, so sharing the per-shard profile is safe;
config.test's resolution-order tests save/restore the env around their
assertions.

* fix(test): landscape --toc gate asserts promotion PRESENCE, not counts

Two rounds of CI receipts: the exact toBe(3) was font-metric-coupled
(3 on Amazon Linux, 2 on ubuntu), and the baseline-comparison repair
then failed 2-vs-3 across renders SECONDS apart in one CI job while the
sibling no-toc test saw 3 — per-render image-promotion timing makes any
count assertion here a coin flip. The sibling test owns exact promotion
counts; this test's actual invariant is that --toc does not break the
promotion machinery: >=1 landscape page + the TOC rendered. Also drops
the second render (halves the test's runtime).

Flaky per-render image promotion itself is worth its own look — noted
in TODOS with these receipts.

* fix(test): per-FILE Chromium profiles for the nine in-process launcher files

Completes the profile-isolation work: the per-shard CHROMIUM_PROFILE
stopped cross-shard kills; these nine files launch in-process
persistent contexts and could still collide with a lingering daemon a
sibling file spawned on the SAME shard profile. Each now scopes a
mkdtemp profile via beforeAll/afterAll (the module-scope-tripwire-safe
pattern), cleaned up per file. All nine green solo and in combined
runs, except the pre-existing commands+snapshot pairing — proven
identical WITH and WITHOUT these edits (baseline receipts) — which is
the daemon-lifecycle follow-up now extended in TODOS with this
session's receipts.

* fix(browse): Chromium-crash exit is daemon-only — embedded launches never kill their host

handleChromiumDisconnect unconditionally process.exit()ed. Correct for
the standalone daemon (its supervisor/user must notice); suicidal when
a TEST launches BrowserManager in-process: a mid-suite Chromium death
exited the whole bun shard with no terminal summary — the exact
truncation class the strict runner flags (observed live: CI shard 1 on
eb233299 died at cache-concurrent-refresh right after a daemon-spawning
gate test; with this fix the same pairing runs to completion and
REPORTS instead of dying).

The standalone entrypoint opts in via markDaemonProcess() under
server.ts's import.meta.main gate — the same embedder contract its
signal handlers already use (gbrowser phoenix keeps its own handlers).
Embedded contexts now get the disconnect log line and continue.

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

* fix(test): context-restore assertion is evidence-based, not prose-matching

The test failed twice per run in TWO CI cycles while passing locally
4/4: the prompt said 'present the content' and the check grepped the
FINAL message for exact phrases — local runs quoted the file, CI runs
paraphrased ('the most recent context is from branch-b...') and the
substring check lost the coin flip.

- prompt now demands machine-checkable output: the newest file's
  '## Working on:' heading VERBATIM + a literal 'RESTORED: <filename>'
  marker (the mtime-scramble and cross-branch subject matter untouched)
- assertion ordered strongest-first: RESTORED marker → legacy content
  phrases → tool-call corroboration (Read/Bash input naming the newer
  file, credited ONLY when the older file was never read — a
  both-files run must still present the right one)
- the older-file negative got STRONGER: an explicit RESTORED marker
  naming the older file fails even if wintermute words appear elsewhere
- sibling scan: context-recovery-artifacts got the additive prompt-side
  treatment only (quote the matched literals verbatim); its lenient
  1-of-6 assertion deliberately unchanged

3/3 consecutive local green with all evidence classes firing
(marker=true, content=true, toolNewer=true, toolOlder=false).

* fix(test): skillify family — HOME==cwd broke project-skill registration

Root cause (forensically pinned from stream-json init events + a
kill-after-init probe): with HOME set EQUAL to the child's cwd, claude
resolves <cwd>/.claude/skills as the PERSONAL skills directory and the
seeded project-tier skills never register — the Skill tool returned
'Unknown skill'. The provenance-refusal test then improvised a refusal
whose wording missed the regex (the deterministic CI+local red); the
happy-path and approval-reject siblings passed only because their
agents self-recovered by Reading SKILL.md manually — silently not
exercising the Skill-tool path at all.

All three tests now use HOME=<workDir>/home (a fresh subdir keeps the
override's intent: child ~/.gstack writes land in the assertable
sandbox, without the cwd collision). Refusal test additionally: a
'not registered/unknown skill' tripwire (a not-loaded skill can never
pass as a refusal) and the refusal regex now matches assistant text
only — the skill BODY echoed into the transcript contains the exact
refusal message, so the old full-surface match could pass vacuously
once the skill loaded. Sibling disk assertions sweep both $HOME/.gstack
and cwd .gstack roots (positives and negatives).

Verified paid: refusal 2x consecutive green with the skill's EXACT
message rendered ('Launching skill: skillify' in-transcript), then the
full file 5/5 green (~$1.35) with both siblings driving real Skill
calls (25-27 turns each).

* docs(TODOS): two of three first-execution findings fixed (skillify family, context-restore)

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

* fix(test): context-restore gets a private home — the REAL root cause was fixture sharing

The evidence-based assertion fix was treating a symptom. The slice
artifact's embedded transcript showed the CI agent restoring
20260829-context-save-skill-test.md — the checkpoint the SIBLING
context-save test wrote into the SHARED gstackHome checkpoints dir,
which by filename-prefix ordering genuinely IS the newest. The agent
behaved CORRECTLY; the test's fixture set was open to concurrent
sibling writes, and bun --concurrent ordering differs between CI (save
finished first) and local (restore listed first) — the entire
local-green/CI-red split explained.

The restore test now uses its own .gstack-restore-home (the whole home
moves, not just the handed path — an agent deriving the dir from
GSTACK_HOME/projects/<slug> must land in the closed set too). Full file
4/4 paid green with all evidence flags firing.

Also: the on-failure shard-log artifact glob uploaded nothing — the
Fix-bun-temp step points TMPDIR at /home/runner/.cache, so the spool
lands there, not /tmp. Both eval workflows now glob both locations
(this gap is why diagnosing THIS failure required digging transcripts
out of the slice-results artifact).

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

* fix(evidence): carry the real index mtime onto gstack-wtree's temp copy

The stat-cache seed (cp of the real index) stamped the temp index "now",
which defeats git's racy-git protection: an entry is only re-hashed when
its cached mtime is not older than the index file itself, so a same-size
rewrite landing in the same second as the last real index write looked
non-racy, kept its stale stat-cache entry, and vanished from the
fingerprint — evidence stayed FRESH after a source change. This is the
CI flake in test/evidence.test.ts "allow-paths carve-out" (sub-second
alignment on fast runners: expected STALE exit 1, got FRESH exit 0).

touch -r restores the original index timestamp, reinstating the exact
racy window git itself uses. Deterministic regression pin in
test/review-log.test.ts reproduces the miss with pinned zero-nsec
timestamps (fails on the old script, passes now); receipts: manual
probe shows the fresh-stamped copy returning the clean tree for a
same-size 'hello'→'howdy' rewrite while the mtime-carried copy detects
it.

* fix(test): landscape gate bounds the promotion count instead of pinning 3

The alt-hinted image promotion rides the per-render measurement race
already filed in TODOS (2-vs-3 landscape pages on renders seconds
apart — CI receipts from PR #2721, now reproduced locally). Pin the
two deterministic promotions as the floor and the three promotable
blocks as the ceiling (anything above 3 means the veto leaked); the
veto/portrait assertions remain exact.

Garry TanandClaude Fable 5 b5a951e623 v1.72.0.0 feat: Aside recommended driver for third-party web actions (#2710) 
* fix(browse): never chmod shared, symlinked, or foreign-owned dirs to 0700

restrictDirectoryPermissions unconditionally chmodded its target. On hosts
where the process holds CAP_FOWNER (Docker as root, CI sandboxes) that
chmod SUCCEEDS on root-owned /tmp whenever a state file is configured
there (BROWSE_STATE_FILE=/tmp/x.json derives stateDir=/tmp), and a 0700
/tmp breaks access(2)-based checks machine-wide for every other process.

The POSIX branch now refuses shared sticky dirs, world-writable mounts
under root, foreign-owned dirs, and symlinked state dirs; refusals warn
once per process instead of failing silent; owned-but-unreadable dirs
keep their chmod self-repair; and the check-then-act race is closed with
fd-anchored O_NOFOLLOW + fstat/fchmod on a single inode.

Regression tests cover the sticky-dir, foreign-uid, mkdirSecure-reapply,
and symlinked-dir shapes.

* fix: hash with sha256sum before shasum on Linux (config slugs + setup verify)

shasum is perl/macOS; coreutils-only Linux ships sha256sum. Two call
sites hard-coded shasum: gstack-config's sha8_of/sha16 (so
resolve-user-slug exited 127 for any Linux user with a git email, the
Layer-3 fallback) and the generated bun-installer checksum snippet in
the browse/qa NEEDS_SETUP flow (spurious "checksum mismatch" on the
same distros). Both now resolve sha256sum first and fall back to
shasum -a 256.

New shim-PATH tests pin BOTH hasher branches of sha8_of to a known
vector and cover the sha8->sha16 collision escalation end to end.

* feat(contract): Aside is the recommended driver for third-party web actions

The Third-Party Web Actions contract (ship, spec, office-hours,
land-and-deploy, setup-deploy) now names the Aside AI browser as the
recommended driver: it acts across the user's real logged-in sessions,
which is what vendor-dashboard moments need. Supersedes the v1.65.0.0
de-Aside stance by explicit user directive (2026-08-27).

Detection is a runtime probe (command -v + aside --version under a
portable gtimeout/timeout/bare guard; nonzero exit = not detected).
Consent options render per detection state with Aside recommended and
the first-party stack ($B headed + handoff, GStack Browser) as the
universal fallback. Absent on macOS, the contract mentions the
aside.com download (macOS 15+) once per task; gstack never runs an
installer and binary presence is never consent. Drive discipline:
step-wise over whole-task delegation, vendor confirm mode on, vendor
skill/--help text scoped to operational syntax only, secrets minimized
(autofill / human-used copy buttons), Apple credential creation never a
drive target in any skill, failure path quotes redacted errors and
falls back only with fresh consent.

test/third-party-actions.test.ts pins every load-bearing sentence (21
tests) plus repo-wide tripwires: an aside command allowlist
(--version/--help only, code spans AND prose) and a ban on Aside
installer invocations across all generated docs. Budget ratchet
fixture and carve skeleton ceilings refreshed in this commit per the
ratchet protocol.

* chore: regenerate remaining browse-setup snippet consumers

The sha256sum-first checksum fallback in the generated NEEDS_SETUP
snippet renders into every browse-consuming skill, not just browse/qa.
Mechanical regen of the other ten consumers; no template changes here.

* test: consent-gate E2E suite + functional fs-capability probes

Five hermetic gate-tier E2E cases (tpa-present / absent-linux / broken /
absent-darwin / apple-ban) drive the real contract section through
claude -p with PATH shims for aside and uname; the absent cases filter
any REAL aside binary out of the child PATH and assert absence with
Bun.which before spawning, so dev machines cannot leak into detection.
Registered per-case in E2E_TOUCHFILES/E2E_TIERS with template-level
deps (ship/SKILL.md.tmpl, gen-skill-docs.ts) and added to the evals.yml
matrix with tier: gate. eval:bg:periodic's detach timeout rises to
36000s for the grown periodic shard census (floor-enforced by
test/eval-detach-timeout-floor.test.ts); CLAUDE.md doc updated to match.

test/helpers/fs-caps.ts adds canRevokeWrites/canRevokeReads functional
probes; 13 chmod-based tests swap their uid-0-only guards for the
probes so suites skip honestly on CAP_DAC_OVERRIDE containers (this
sandbox: uid 1000 with full caps) instead of asserting revocations the
kernel ignores. path-validation's symlink test targets /etc/passwd
(exists everywhere; /etc/crontab is absent on Amazon Linux).

* docs: file the Aside follow-ups in TODOS

Phase-2 QA logged-in-evidence path (P3), a hostile-vendor-skill E2E for
the contract's override sentence (P2), and fd-anchoring the file-level
permission writes to match the directory hardening (P3).

* fix(test): gate the symlink-refusal test to POSIX and drop the umask assumption

The symlink regression test exercised the POSIX O_NOFOLLOW branch but ran
on Windows, where restrictDirectoryPermissions takes the icacls branch and
stat has no POSIX modes (0o666 always) — windows-free-tests failed on
mode 493 vs 438. Early-return on win32 like every sibling test in the
file, and assert the target's mode is UNCHANGED (captured post-mkdir)
instead of hardcoding 0o755, which a strict umask would also break.

Garry TanandClaude Fable 5 394db326f2 v1.71.0.0 feat: token-load reduction — preamble runtime scripts, gated onboarding, 20 skill carves, CLAUDE.md trim (#2691) 
* feat(gen): strip gen-time-only frontmatter keys from Claude renders

interactive + benefits-from are read from the .tmpl by buildContext at
generation time; no runtime, host, or test reader consumes them from the
generated SKILL.md (e2e-harness-audit reads .tmpl; benefits-from tests
assert rendered prose). gbrain: stays (bin/gstack-brain-context-load reads
it from the installed render); hooks: stays (Claude Code host wires
PreToolUse from it).

* chore(gen): regenerate SKILL.md — dead frontmatter keys removed

Mechanical regen after hosts/claude.ts stripFields change.

* feat(test): context-budget ratchet — CI ceilings on always-on + eager token ledgers

New free test grades the two ledgers nothing else guards: the full-frontmatter
always-on catalog (aggregate) and per-skill eager tokens (SKILL.md +
forced-read refs), via checkBudget from lib/context-bill.ts. Ceilings live in
test/fixtures/context-budget.json with x1.05/x1.10 headroom; regenerate with
bun test/helpers/capture-context-budget.ts. New skills fail until consciously
budgeted; removed skills fail until the fixture is refreshed; reductions
ratchet the ceilings down so wins lock in.

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

* docs(todos): file output-template carve wave + plan-ceo doctrine revisit; mark preamble-carve P3 in flight

Two follow-ups deferred from the approved token-reduction program (CEO review
'NOT in scope' list), filed with full context per TODOS format. The existing
P3 preamble-carve entry gets a status update pointing at the program that
supersedes it.

* fix(test): review findings — Windows path normalization, full totals rebuild, ratchet coverage

Pre-landing review (5 specialists) found one critical: the ratchet test runs
in the curated Windows lane, where path.relative yields backslash skill names
that miss the test/ filter and mismatch every POSIX fixture key. Names are now
normalized once in buildRatchetBill (toPosixName) and the fixture filter is
tightened to test/fixtures/. All eight Bill.totals fields are rebuilt from the
filtered list (no fixture-polluted perInvocation/totalMd numbers for future
consumers). New coverage: Windows-separator normalization pins, a
captureContextBudget round-trip against tree-a (headroom math exact), a
stripFields regression pin (interactive/benefits-from absent from renders,
hooks/gbrain preserved), and the ceilings test no longer double-reports
stale-fixture entries.

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

* fix(test): adversarial findings — stable root key, symlink-alias dedupe, fixture-shape guard

Adversarial review (Claude subagent) verified the fixture's root-skill key was
the capture machine's checkout dirname: any non-gstack-named clone (every
Conductor worktree) failed the free suite, and the documented re-run-the-capture
recovery baked the local dirname into the committed fixture — silent corruption
through the tool's own protocol. The root skill is now pinned to ROOT_SKILL_KEY
('gstack', its frontmatter name). Symlink aliases are realpath-deduped (census
precedent): connect-chrome no longer gets its own ceiling, so Windows checkouts
that materialize the symlink as a plain file can't fail the stale-ceiling
set-equality test. New guards: fixture-shape validation (a string alwaysOnTotal
can no longer silently disable the ceiling), a mutation pin that the filter
shrinks the always-on ledger vs the raw bill, an alwaysOnTotal violation test
(the branch was load-bearing with only under-budget coverage), and an atomic
temp+rename fixture write. Fixture regenerated: 59 ceilings, alwaysOnTotal 6344.
Deferred with a TODO: anchoring transformFrontmatter's denylist strip to the
frontmatter block (latent, zero live collisions, pre-existing path).

* chore: bump version and changelog (v1.69.1.0)

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

* docs: update project documentation for v1.69.1.0

CLAUDE.md: Token ceiling section documents the context-budget ratchet as
the third guard (test file, fixture, new-skill budgeting, capture command).
CONTRIBUTING.md: Tier 1 guard list gains a Context-budget ratchet bullet;
the Adding-a-new-skill checklist gains the budget-capture step.

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

* docs: pin exact guard semantics for the context-budget ratchet in CLAUDE.md

Doc-review finding: "a third enforced ceiling" undercounted the guard
family (skill-size-budget floors and parity ratios also watch these
ledgers, relatively). Rephrased to match the ratchet test's own header:
absolute ceilings vs relative floors/ratios.

* docs(changelog): heaviest-skill claim matches the fixture (land-and-deploy edges review by 0.2%)

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

* feat(bin): gstack-skill-start + gstack-skill-end — the preamble runtime, consolidated

Absorbs the ~13KB of bash every tier-2+ SKILL.md inlined twice over (bootstrap
fence + artifacts-sync fence) and the skill-end telemetry/sync fences. Same
KEY: value STATUS-line contract the prose interprets, plus SKILL_START_PROTO
handshake (OV5), SESSION_ID/TEL_START echoes, GSTACK_HOME-normalized state
paths (EOV7), --parent-pid session identity (EOV5: $PPID inside the script is
the ephemeral tool-call shell), OV4 sanitization of passthrough output, and a
receipted daily artifacts pull (_receipted_git, brain-sync class, fail-closed).
Per-line || true error style throughout (F3) — a mid-script failure never drops
later STATUS lines.

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

* feat(gen): preamble resolvers emit a script invocation fence instead of inline bash

generate-preamble-bash: ~6.3KB fence -> 4-line gstack-skill-start invocation
(quoted-tilde pitfall handled: leading ~ interpolates through $HOME; env-var
hosts keep $GSTACK_BIN) + degraded-mode prose (F1/EOV8: safe defaults, consent
gates deferred-never-lost; OV5: proto rule). generate-brain-sync-block: ~6.8KB
bash -> interpretation prose + the privacy stop-gate (stays inline until
Phase 2's gated emission). generate-completion-status: telemetry fence -> one
gstack-skill-end call with SESSION_ID/TEL_START handoff.

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

* chore(gen): regenerate all skills + golden fixtures — inline preamble bash removed

Mechanical regen after the resolver change: −12,628 lines across 52 renders
(corpus 952K -> 806K render tokens; tier-2 skills −11-13KB each). Golden
per-host ship fixtures refreshed from the fresh claude/codex/factory renders.

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

* test: skill-start contract suite + preamble A/B eval + touchfiles registration

test/gstack-skill-start.test.ts (11 free tests): STATUS-key contract vs the
prose (F2), per-host fence resolution shapes (E1), proto-first, OV4 marker
sanitization, --parent-pid identity, headless suppression, skill-end duration
math + pending cleanup. test/skill-e2e-preamble-script-ab.test.ts (gate tier,
OV7): inline-bash render (pinned from 29785978) vs script render with the
fence redirected at the worktree bin (EOV2 — hermetic evals otherwise resolve
the operator install and silently exercise degraded mode). 21 touchfiles dep
lists gain the two bin scripts (EOV9) so future script edits select the
preamble evals; selection-count pin updated 23->24.

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

* test: repin ~70 assertions to the script contract — every literal gets a successor

Assertions that pinned inline-bash internals (update-check guard, _SESSIONS
reaping, telemetry start/end blocks, routing probe, repo-strip producer,
first-task gating, EXPLAIN_LEVEL/QUESTION_TUNING echoes, #2499 jq scope
resolution, Issue-8 CONDUCTOR gate) now pin the same invariants in their new
home: bin/gstack-skill-start / bin/gstack-skill-end file content for script
internals, the invocation fence + interpretation prose for render-side
behavior. No assertion deleted without a successor; live-execution tests
(routing probe, brain-sync jq) run against script bytes unchanged.

* chore(test): re-baseline size floors + ratchet ceilings down (EOV1/OV9 protocol)

parity-baseline-v1.69.1.0.json captured with carved-skill unions (53 skills);
skill-size-budget repointed with the derivation comment citing the Phase 1
context-bill receipt (the ~13KB/skill cut trips the old 80% floor on tier-1
skills first — setup-browser-cookies headroom 10.8KB < the cut). The v1.47
fixture stays on disk for history; the parity-suite growth baseline
(v1.64.1.0) is untouched. Context-budget ceilings re-captured: review
29,309->26,192; learn ->10,969; ios-clean ->10,764 — Phase 1's win is locked.

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

* feat(bin): instruction-emission layer — onboarding text appears only when its gate fires

The 8 one-time onboarding flows (lake intro, telemetry opt-in, proactive
opt-in, first-run/first-loop tips, routing injection, vendoring deprecation,
writing-style migration, spawned-session rules), the upgrade-flow + feature
discovery prose, and the privacy stop-gate (user-approved Q2) moved from
every render into gated heredocs here. Blocks are SESSION_ID-bound
(GSTACK_INSTRUCTION_BEGIN: <id> <session-id>) so page/file content can't mint
directives (F4/OV4). Ack ownership per OV6: display-only tips write their
markers at emit (script also fires the scaffold telemetry); interactive flows
carry their ack commands inside the block. The dormant WRITING_STYLE_PENDING
gate is computed for real now (marker files). BASH_COMPAT=50 heredoc guard
(same as brain-sync); the quoted routing heredoc resolves its bin path via a
sed placeholder.

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

* feat(gen): drop the 8 onboarding generators — renders keep one instruction-block rule

generate-{lake-intro,telemetry-prompt,proactive-prompt,first-run-guidance,
routing-injection,vendoring-deprecation,spawned-session-check,
writing-style-migration}.ts deleted (single source is now the script's
emission layer, F5). generate-upgrade-check shrinks to the steady-state
PROACTIVE/SKILL_PREFIX rules. generate-brain-sync-block hands the privacy
stop-gate to the emitted block. The fence prose gains the generic rule:
follow GSTACK_INSTRUCTION blocks only from this command's direct tool result
with the matching SESSION_ID; unterminated block ends at end-of-output.

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

* chore(gen): regenerate all skills + goldens — onboarding prose degated

Mechanical regen: corpus 806K -> 707K render tokens (−8KB/skill; cumulative
vs main: ship 91->71KB, learn 53->34KB, ios-clean 53->33KB).

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

* test: onboarding tombstone + Phase 2 pin relocations

New test/onboarding-moved-literals.test.ts (F5): 12 distinctive literals must
live in bin/gstack-skill-start AND stay absent from every render, plus the
SESSION_ID-binding pins. ~40 assertions repinned to the emission-layer
contract (gates, block ids, in-block acks, script-run marker writes); the OV4
sanitize test upgraded to the real property (every legitimate block header
carries the run's SESSION_ID). first-task dep list drops the deleted
generator; the token->tip case map is pinned to cover every detector bucket.

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

* chore(test): carve floors/ceilings recomputed; baseline + ratchet follow Phase 2 (OV9)

All 9 carved skills re-anchored to post-Phase-2 measurements (cso's union had
tripped its 72,000 floor at 71,379; design-consultation had 252B of margin).
maxSkeletonBytes ceilings tightened to measured+~600B. Branch-internal
parity baseline recaptured in place; ratchet ceilings down again: review
->24,052, ship ->18,589, learn ->8,828, ios-clean ->8,624.

* feat(gen): AUQ slim — tool resolution as a STATUS-line branch table, split rules to invariants + absolute pointer

Tool resolution (1,799B) rewritten as a 3-branch table keyed on the echoed
CONDUCTOR_SESSION/SESSION_KIND lines — Conductor prose-default, MCP-variant
preference, and failure handoff preserved verbatim in behavior, including the
auto-decide-first ordering and the gstack-question-log capture requirement.
5+-options handling (1,924B) compressed to the split invariants (never drop;
D<N>.k shape; Include/Defer/Cut/Hold; question_id scheme with the never-ask
refusal) + the full-rule pointer. Both doc pointers now interpolate the
absolute install root (Codex outside-voice #7 convention) instead of the bare
'in the gstack repo'. Failure-fallback, Format, and self-check sections are
byte-identical — all 14 MANDATORY always-loaded pins pass with zero test
edits.

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

* chore(gen): regenerate all skills + goldens — AUQ slim

Mechanical regen: −1.3KB per tier-2+ skill (ship 69.9KB, learn 32.5KB).

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

* chore(test): baseline + ratchet follow Phase 3 (OV9); OV8 evaluated — shrink floor stays

Branch-internal baseline recaptured; ratchet ceilings down again. OV8's
floor-retirement question, evaluated as planned after Phase 3: the 80% shrink
floor stays — it uniquely catches accidental body deletion in non-carved
skills BETWEEN ratchet recaptures, and the capture command has amortized the
fixture-refresh cost that motivated retiring it.

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

* feat(review): carve adversarial, plan-completion, and review-army into sections

The three resolver macros ship already carves as siblings now load on demand
for /review too: skeleton 100.2KB -> 55.0KB (-45%), union 93.4KB. Resolvers
stay the single source of truth (sections wrap the macros). Step 0/1, scope
drift, critical pass, confidence calibration, and fix-first stay always-loaded.
Fixtures and pins follow the moved content (codex-hardening wrapped-sites,
review-army E2E fixture builds skeleton+sections with an empty-fixture guard).

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

* feat(codex): carve the three mutually exclusive modes into sections

Review/Challenge/Consult mode bodies (34.7KB where at most one ever runs)
load on demand: skeleton 81.0KB -> 55.2KB, union 1.04x the monolith. The mode
dispatch, filesystem boundary, and a new always-loaded 'Synthesis
recommendation (REQUIRED) — all modes' block stay skeleton-side (the AUQ
per-skill pins pass unchanged); the plan-file report + exit gate render after
the last section pointer per the gateAfterStop pattern.

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

* feat(land-and-deploy): carve first-run validation, readiness gate, and merge/deploy into sections

The once-per-repo dry-run validation, the pre-merge readiness gate, and the
merge + deploy-strategy steps (37.8KB) load on demand: skeleton 91.1KB ->
55.7KB. Step 1.5 keeps its detection bash as the dispatch; the first-run
section's fingerprint-save block gained {{SLUG_EVAL}} so it is self-contained.
Zero content lost (line-coverage checked against HEAD).

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

* feat(ios): demote the four ios skills to preamble-tier 2 (Phase 5)

They never consume the tier-3 sections (repo-mode ownership, search-before-
building) but do fire AskUserQuestion, which tier >=2 provides — verified by
grep before the plan review. -2.2KB per skill. Render assertions pin the
demotion (tier-3 sections absent, AUQ format present).

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

* chore(guards): register wave-1 carves; monolith invariants retire; baselines + ratchet follow

CARVE_GUARDS gains review/codex/land-and-deploy (12 carved skills total);
their MONOLITH_INVARIANTS entries retire (invariants now generate from the
registry, cso precedent). Touchfiles: carve-section-loading covers the three
new carves; the codex + land-and-deploy LLM-judge dep lists widen to their
sections. Regen + goldens + branch-internal baseline + ratchet ceilings
recaptured (review 24,052 -> skeleton-based ceiling; union floors hold).

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

* test(gen-skill-docs): review render pins read the carved union

The review carve's readSkillUnion conversions (same pattern its neighbor
carved-skill pins already use).

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

* feat(autoplan): carve the four review phases + tasks aggregator into sections

Phase bodies (CEO/Design/Eng/DX consensus flows) and the Implementation Tasks
aggregator load on demand; Design and DX stay separate sections because each
is independently conditional on scope. Skeleton 83.7KB -> 58.7KB (-30%
always-loaded); the 6 decision principles, classification, sequencing, and
explicit skip-condition dispatch stay always-loaded. The chain E2E's
phase-complete markers now live only in sections, so its assertions double as
section-read proof (behavioral: external).

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

* feat(spec): carve the post-confirmation gate-and-file tail into one section

Phases 1-4 are the turn-1 conversational spine — carving them would force the
Read on the first user message for zero real savings. The mechanical tail
(4.5/4.5a/4.5b redaction gates + Phase 5 filing + TTHW telemetry) fires only
after draft confirmation: a genuine lazy boundary, kept as ONE section so the
gh-issue-create bash can never load without the fail-closed redaction gate
that precedes it. Skeleton 65.4KB -> 50.7KB; all ~85 phase-structure
invariants migrated location-aware plus a new carve-shape suite (56 tests).

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

* feat(setup-gbrain): carve the branch-exclusive install paths into sections

Brain-init (Paths 1/2/3/4 bodies), engine remediation, transcript gate, and
CLAUDE.md persist load on demand — at most one install route ever runs.
Skeleton 75.3KB -> 57.0KB; the Step 1 detect and Step 2 path dispatch stay
always-loaded. New buildSetupGbrainFixture helper gives the periodic E2Es
extract-don't-copy fixtures with a non-empty guard; the voyage-code-3 gate
counts scan the tmpl union (the third init site lives in engine-remediation).

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

* chore(guards): register wave-2 carves (15 carved skills); autoplan monolith retires; baselines follow

CARVE_GUARDS gains autoplan (behavioral: external via the chain eval), spec,
and setup-gbrain; autoplan's MONOLITH_INVARIANTS entry retires. Touchfiles:
setup-gbrain periodic dep lists gain the section tmpls + fixture helper; the
stale-brain-refs scan covers setup-gbrain/sections. Regen + goldens + branch
baseline + ratchet recaptured.

* feat(qa): carve QA patterns + health rubric into on-demand sections (68→48KB skeleton)

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

* feat(browse): carve full command list + snapshot flags into sections/command-list.md (39→27KB skeleton)

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

* feat(retro): absorb inline git/awk metrics into bin/gstack-retro-metrics + carve report format

RETRO_METRICS_PROTO: 1 contract, local git reads only (fetch stays in the
skill prose), degraded path documented in the skeleton.

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

* test: register wave-3 carves (qa, browse, retro) — guards, touchfiles, pins, baselines

CARVE_GUARDS gains the three entries; qa's monolith invariant retires.
auq-format carve-safety now keys on the skeleton+sections union shipping
the AUQ block (first tier-1 carve: browse never renders it by design).
Baselines: parity v1.69.1.0 at 18 sectioned skills; ratchet recaptured.

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

* fix(test): drop stale generate-lake-intro import (generator deleted in the emission-layer move)

Sol scope discipline stays pinned via the model overlay + completeness
section; the lake intro is now a single script-emitted blurb.

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

* feat(office-hours): carve Phase 2A/2B into mode-exclusive sections (81→67KB skeleton)

A session runs exactly one mode, so a builder session never loads the
13KB startup diagnostic. Mode mapping and the vibe-shift upgrade rule
stay in the skeleton.

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

* feat(design): carve UX doctrine + Pretext patterns into read-on-demand sections

design-html 57→49KB, design-shotgun 53→50KB. Sections wrap
{{UX_PRINCIPLES}} so scripts/resolvers/design.ts stays the source of
truth; the pretext-patterns STOP sits at the top of Step 3 so the read
provably precedes the Write.

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

* test: register wave-4 carves (office-hours ext, design-html, design-shotgun) — 20 carved skills

Both design entries carry requiredReads + loading-eval scenarios (D3A
condition). office-hours phase sections are mode-exclusive, so only the
always-reached design/handoff section is a deterministic requiredRead.
Baselines and ratchet recaptured.

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

* docs: trim CLAUDE.md 66.4→44.9KB — verbatim moves to docs/, pointers stay inline

Moved: browser/sidebar/server internals, CHANGELOG release-summary format
spec, project tree, hermetic-E2E detail, slop-scan reference, OpenClaw
publishing. Kept inline: every hard behavioral rule (dist/ ban, redaction
scan-at-sink, egress receipts, bisect commits, eval detach, CHANGELOG
entry rules), the machine-managed GBrain block (byte-identical), and the
'## Deploying to the active skill' header with gbrain-refresh in range
(pinned by test/gbrain-refresh-install-render.test.ts). No voice rewrites.

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

* fix(test): seed onboarding markers into the hermetic child GSTACK_HOME

EOV7 made bin/gstack-skill-start honor GSTACK_HOME, so the operator-HOME
seeding in e2e-helpers.ts no longer reaches hermetic children — the
emission layer fired lake-intro/telemetry prompts that burned turns and
stalled PTY tests waiting on an answer (observed: plan-mode-no-op derailed
by the telemetry question). Onboarding-specific tests pin their own
GSTACK_HOME per-test, which merges over this seed.

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

* test: raise carve-section-loading wall clock to 480s SDK / 540s bun

The heavy full-workflow scenarios satisfy their required section reads
inside 60s but need 300-450s to finish the report on slower sandboxes;
the 300s default read as a loading failure when the carve invariant held
(traces: plan-eng-review read its section at 8s, office-hours all three
at 24s, design-html both at 50s — all timed out mid-report).

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

* fix(security): harden the skill-start trust boundary — review-army findings

Session ID gains a urandom suffix (block binding unforgeable by reflected
content); _sanitize also neutralizes spoofed SESSION_ID: lines; branch
names are charset-clamped before JSON embedding (skill-start + skill-end);
.brain-last-push reads first line only with a charset clamp; the artifacts
URL echo routes through _sanitize; the privacy consent gate fires in
interactive sessions only (spawned auto-choose could accept consent no
human gave — emission order is not a safety property); the daily pull gets
non-interactive + slow-network git guards and stamps only when the
receipted path ran; ~/.claude.json gets a grep pre-filter before the jq
parse.

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

* fix(resolvers): question-log session_id becomes a substitution placeholder + stale-comment sweep

The question-log block bound $_SESSION_ID, a shell variable the
consolidated fence never sets — hook-less hosts logged empty session_id,
breaking /plan-tune per-session grouping. It now uses the same
substitute-from-the-skill-start-echoes contract as the telemetry block.
Also: retired the pre-Phase-2 stop-gate docstring, repointed the
gbrain-local-status cross-reference at the script's inline jq, dropped an
orphaned section comment, documented retro-metrics' suffix-only census.

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

* chore: regenerate renders for the question-log placeholder; goldens + baselines follow

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

* test: hermetic update-check, onboarding gate sequencing, seeding parity

The contract test's child did a live git ls-remote + curl to github.com on
every bun run test (update_check config now gates it off); the headless
test gets a fresh GSTACK_HOME so the suppression is actually exercised; a
new OV6 test drives the script three times to pin ack-at-emit and gate
sequencing; hermetic seeding covers the config-keyed privacy gate; the
EVALS_HERMETIC=0 debug seeding reaches marker parity.

* test(ci): demote the preamble A/B to periodic (OV7) and add it to the periodic matrix

Post-Phase-3 demotion per the plan; the eval needs fetch-depth 0 (it git
shows a pre-Phase-1 sha), which only the periodic workflow provides — and
a static matrix entry so it can't silently never run.

* chore: bump version and changelog (v1.70.0.0)

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

* docs: update project documentation for v1.70.0.0

ARCHITECTURE.md: the preamble section now describes the v1.70 runtime —
the rendered {{PREAMBLE}} block invokes bin/gstack-skill-start and reads
STATUS lines, gstack-skill-end logs telemetry, and one-time onboarding
text arrives as gated GSTACK_INSTRUCTION blocks instead of riding in
every render.

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

* docs: doc-review fixes — repair moved-file links, drop unbacked session-count claim

docs/BROWSER_INTERNALS.md: the two ARCHITECTURE.md anchor links broke when
the section moved from repo-root CLAUDE.md into docs/ — now ../ARCHITECTURE.md.
ARCHITECTURE.md: the preamble's session-tracking item claimed an active-session
count and an "ELI16 mode" that no shipped code implements (the count
computation was deleted with the inline preamble); describe the real
touch-and-prune behavior instead.

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

* docs(changelog): correct numeric claims against measured counts

50 of 62 installed skills dropped (fixture/alias entries have no preamble);
11 new carves + a deeper office-hours carve = 9→20; test counts match the
files (13 / 11 / 3 / 7).

* test(e2e-design): widen the Aesthetic synonym set — vocabulary variance, not a regression

Both attempts in run 33090283032 produced judge-praised DESIGN.md files

* fix(test): stage design-consultation's sections/ into the E2E fixture

The skill has been carved since v1.57.0.0 — the DESIGN.md structure
prescription (the AESTHETIC proposal template) lives in
sections/proposal-and-preview.md behind a STOP-read. The fixture only
copied SKILL.md, so the agent improvised structure from the skeleton and
the section-synonym check has been a coin flip since the carve (CI run
33090283032 trace shows 'no sections dir'; the local eval store has the
same failure on 2026-08-25 while that day's CI run passed on lucky
vocabulary).

Garry TanandClaude Fable 5 a3749bfa4b v1.70.1.0 fix: ship names the /document-release subagent at every decision point (tripwire + gate E2E) (#2700) 
* fix(ship): name the /document-release subagent at every Step 18 decision point

The v1.54.0.0 carve moved Step 18 (documentation sync) into
ship/sections/pr-body.md and the Claude-host skeleton stopped saying
"document-release" anywhere in the workflow body — the dispatch became
invisible at exactly the moments an agent decides whether to open the
section. Restore visibility at three touchpoints, all subagent-framed
(never bare-slash-framed, which would invite an inline Skill invocation
that bypasses the fresh-context subagent + JSON contract):

- manifest trigger (renders into the section-index row AND the STOP
  pointer): "dispatching the /document-release subagent to sync docs
  (Step 18) and then creating or updating the PR/MR (Step 19)"
- Step 17 handoff line names Step 18's dispatch explicitly
- new hoisted doc-sync invariant beside the PR-title invariant: the
  dispatch itself is never skipped; only a failed subagent is
  non-blocking

Pin it in carve-guards: 'the /document-release subagent' (all three
touchpoints) + 'dispatches the /document-release subagent' (invariant)
must stay in the skeleton; the carved imperative 'Dispatch
/document-release as a subagent' must stay carved. Skeleton cap
91,600 → 92,300 (measured 91,764; trigger renders twice). Goldens
regenerated for all three hosts.

* test: pin the ship→document-release Step 18 wiring with a free tripwire

Five substring/structure asserts across the carved section, the Claude
skeleton's three touchpoints, the manifest trigger, and the codex/factory
goldens (inlined Step 18 ordered before Step 19). Claude-golden asserts
deliberately omitted: host-config.test.ts already enforces golden ==
generated byte-for-byte.

* test: gate-tier E2E proving /ship dispatches the document-release subagent

New skill-e2e-ship-docsync: a live agent gets the sliced Step 17→19 tail
of the generated ship skeleton in a bare-remote git fixture (Steps 0-16
"done"), under a fake HOME so the STOP pointer and the Step 18 subagent
prompt resolve to planted copies, with a stub document-release skill that
returns the empty-result JSON contract. Hard assert: an Agent/Task
tool-call matching /document-release/i exists in result.toolCalls and
precedes any `gh pr create`. Neutral prompt (no STOP-Read priming, no
document-release mention — the prompt echoes into the transcript, so
asserts read toolCalls only).

Hardening from review: throw-on-marker-drift fixture slice; per-test
GSTACK_HOME + .redact-prepush-prompted marker (routes Step 17's
credential guard to its silent branch — the hermetic GSTACK_HOME pin
defeats a HOME-only override); 480s/540s timeouts (nested subagent adds
wall clock the 300s sibling never carried); 'timeout' accepted in
exitReason only because the dispatch assert is independently hard;
whole-file describeE2ETier('gate') composed with diff selection (keeps
the file out of the periodic shard census, which sits at its ceiling,
and under the hard tier-alignment invariant).

Registered as 'ship-docsync' in E2E_TOUCHFILES + E2E_TIERS (gate) in the
same commit — touchfiles.test.ts rejects either half landing first.

* docs: fix stale document-release TODOS entry + three review-deferred items

The SHIPPED entry still described the deleted Step 8.5 post-PR cat-delegation
design from v0.8.4; replace with the current Step 18 subagent design and its
test pins. Add the three P3 items deferred from the v1.69 plan review:
dispatch receipt enforcement, land-and-deploy→canary dispatch-pin pattern,
and the periodic shard-census boundary.

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

* fix: pre-landing review fixes

Testing-specialist findings, all mechanical: (1) pin the E2E fixture's git
branch (-b main / init.defaultBranch=main) and assert every setup command's
exit status so operator git config can't silently corrupt a paid run;
(2) tighten the dispatch matcher to Step 18-prompt-specific markers
(document-release/SKILL.md | executing the /document-release workflow) so a
subagent merely quoting section text can't false-pass the regression assert
(verified against recorded burn-in transcripts); (3) replace the subsumed
carve-guards anchor with three non-overlapping per-touchpoint anchors
(gerund/imperative/3rd-person) so each touchpoint is independently enforced.

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

* fix: red-team review fixes

Five informational findings: TODOS shard-census arithmetic corrected (census
is 67 with one free ungated slot; the SECOND ungated file trips the floor)
and version pointer fixed (v0.18.2.0, not v0.18.1.0); the free tripwire now
pins the two dispatch-matcher marker strings so a pr-body prompt reword
fails the free suite instead of surfacing as a paid-tier mystery; the E2E
matcher gains a section-paste exclusion (scaffold strings disqualify) —
verified against all recorded runs; the E2E header documents the tierless
test:evals invisibility tradeoff.

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

* fix: adversarial review fixes

Pin the E2E matcher's two EXCLUSION markers in the free tripwire (an
unpinned 'Parent processing:' reword would silently deaden the
section-paste guard while every test stayed green); add an ordering pin
(the hoisted doc-sync invariant must sit above the pr-body STOP pointer —
presence-only anchors can't catch drift below it); plant a third
cwd-relative pr-body copy inside the fixture repo, gitignored so the agent
never tries to commit test scaffolding.

* docs: CHANGELOG accuracy fixes from the doc-release review

Three factual corrections the Step 18 doc subagent caught in the fresh
v1.70.1.0 entry: 5 tripwire tests (not 6), cost floor $0.63 per the cited
eval store (not $0.59), and the visibility claim scoped to decision points
(the re-run checklist mention survived the carve). Plus the E2E header's
stale pending-burn-in note replaced with the observed numbers.

* fix: raise bun-polyfill subprocess budget to 60s for degraded Windows runners

The 50ms-sleep test blew the 20s budget on BOTH bun retry attempts on PR
#2700's windows-latest runner (run 32989821401) — sustained AV/runner
pressure, not just the documented cold-start. Same flake passed-on-rerun on
the prompt-token-load-reduction branch yesterday. Budget only; every
assertion still checks exact output.

* fix(ci): run the ship-docsync gate E2E in the evals matrix + silent-skip tripwire

The evals.yml matrix is hand-enumerated and the Run step never exported
EVALS_TIER, so the new whole-file-gated ship-docsync E2E would have
self-skipped even with a row — a hollow green one layer deeper than the
documented rehomed-monolith incident. Add the e2e-ship-docsync row with a
row-level `tier: gate` property, exported as EVALS_TIER by the Run step
(empty = unset for every existing row: all readers are `=== '<tier>'` or
truthiness).

New free tripwire test/evals-workflow-matrix.test.ts ratchets the class:
matrix files must exist; gate-hosting files must have a row; whole-file-gated
matrix files must carry a matching row tier; and the burn-down lists enforce
their own cleanup. It enumerates the PRE-EXISTING holes found while wiring
this (8 gate-hosting files with no row; codex/gemini rows running zero tests;
the pty-plan-smoke row hollow since its files adopted describeE2ETier) —
tracked in TODOS as the CI gate-lane hollow-coverage burn-down.

 		ad8400543c v1.69.0.0 fix: the silent-failure wave — 6 fixes, 5 community PRs absorbed, tracker closed with receipts (#2666) 
* test(wireup): make gbrain-missing PATH fixture hermetic

The gbrain-missing test appended the host PATH (and a hardcoded /opt/homebrew/bin) to the fixture PATH, so on any machine with a real gbrain installed the 'missing' case saw it, exited 0 instead of 2, and could never fail where the bug exists — a false green for a whole machine class. The fixture now keeps only root-owned OS dirs on the child PATH, and a new determinism check plants a host-like gbrain to prove it is unreachable.

* fix(evidence): stop bun's dotenv autoload from reaching the spawned command

`bin/gstack-evidence` has a `#!/usr/bin/env bun` shebang, and bun AUTO-LOADS
`.env`, `.env.<NODE_ENV>` and `.env.local` from the cwd into `process.env`. The
wrapper then spawned the command with no `env` override, so every command run
through it inherited those variables — and a repo `.env.local` routinely holds
production credentials.

Two things go wrong, and the second is worse than the leak:

1. Secrets reach a child that would not otherwise have them. `npm test` run by
   hand in the same shell sees none of them; the same command through the wrapper
   sees all of them.
2. THE COMMAND UNDER TEST BEHAVES DIFFERENTLY, so the ledger certifies a run that
   is not the run CI performs. Observed in a Next.js repo on 2026-08-20: four
   tests failed 4/4 through the wrapper and passed 5/5 without it, because app
   code branched on env vars only the wrapper supplied. Nearly an hour went into
   chasing a "flake" that was the measuring instrument. The wrapper exists to
   record trustworthy evidence, so silently altering the environment defeats its
   purpose.

The fix builds the child env from `process.env` minus the keys bun injected, and
detection is exact rather than heuristic: verified on bun 1.3.11, a dotenv file
does NOT override a variable the shell already exported (the shell's value wins).
So a key whose live value equals the dotenv file's value was injected by bun, and
dropping it restores the environment the user's own shell would have given the
command. A key whose live value differs is genuinely the caller's and survives.

`BUN_DOTENV_FILES()` mirrors bun's precedence, including that `.env.local` is
skipped when NODE_ENV is "test" — scrubbing a key bun never loaded would strip a
variable the caller legitimately provided.

Escape hatch: GSTACK_EVIDENCE_KEEP_DOTENV=1 keeps the old behaviour. When keys are
scrubbed the wrapper warns with the KEY NAMES ONLY, so the diagnostic cannot
become the leak it prevents.

Tests: 6 cases, mutation-verified — removing `env: spawnEnv` reddens exactly the
two leak tests and restoring it gives 30/30. Every leak test asserts the scrub
warning fired, because `bun test` sets NODE_ENV=test and the first version of
these tests passed vacuously against a `.env.local` bun had never loaded.

Absorbed from PR #2652 with authorship preserved. Wave additions: a doc-comment on the ${VAR}-expansion limitation (bun expands refs, the reader compares raw text — those keys are left in the child env, failing open) and a regression pin for the unreadable-.env fail-open path with a functional DAC-override skip guard.

Fixes #2624

* fix(setup): reap dangling skill dirs when the payload is gone

cleanup_old_claude_symlinks derived its work list from the payload directory, so when the payload was gone — precisely when orphans exist — the glob matched nothing and the loop never ran; the -f guard also followed symlinks, hiding dangling SKILL.md links even with a payload present. The cleanup now scans the DESTINATION skills dir (-e/-L, so dangling symlinks are visible) and anchors SKILL.md provenance to path segments (gstack/*, */gstack/*, */.gstack/render/claude/*) instead of a bare *gstack* substring that would eat a user skill under ~/tools/gstack-fork/. The Windows real-file arm stays payload-gated: a real file has no provable owner.

Absorbed from PR #2634 (2 commits squashed) with authorship preserved. The symmetric cleanup_prefixed_claude_symlinks hole is filed as a TODOS.md residual in this wave.

Fixes #2204

* fix(redact): tolerate EEXIST from recursive mkdir in install-prepush-hook on bun/Windows (#2635)

fs.mkdirSync(dir, { recursive: true }) is a no-op on an existing directory
in Node, but bun on Windows throws EEXIST - crashing hook install on any
repo whose .git/hooks already existed, leaving the repo unprotected.

Add lib/fs-utils.ts mkdirpSync: swallow EEXIST only when statSync confirms
the path is an existing directory; a regular file occupying the path, a
stat failure, or any other errno still rethrows. Use it in
installPrepushHook().

The regression test emulates the Windows bun fs semantics via a
bun --preload fixture, so the exact crash path runs (and fails on the old
code) on any platform, including CI Linux.

Absorbed from PR #2641 with authorship preserved.

Fixes #2635

* fix(bin): route remaining Windows-reachable mkdirSync sites through mkdirpSync

Sweep follow-up to #2641's lib/fs-utils.ts helper: bun on Windows throws EEXIST from a recursive mkdir on an existing dir, so every unguarded recursive mkdirSync on a Windows-reachable path is a latent crash. Converted: bin/gstack-decision-log (unguarded, runs on every decision log — the second call on any machine hits the pre-existing projects dir), bin/gstack-evidence logsDir + ledger dir sites, and bin/gstack-redact-prepush's skip-log site (already try-wrapped, so its failure mode was a silent skip-log loss rather than a crash — the fix makes the log survive). The ~15 remaining gbrain/mac-lane sites are deliberately left alone.

Regression: fs-utils.test.ts drives gstack-decision-log twice, the second run under the bun-Windows EEXIST preload fixture — the pre-sweep code exits 1 with EEXIST there; verified red against v1.68.3.0.

* fix(setup-gbrain): warn about the ZeroEntropy sunset before Sept 4

ZeroEntropy was acquired by Notion and sunsets its hosted API on September 4, 2026. A gbrain configured with the zeroentropyai embedding recipe keeps importing pages after that date but embedding silently fails — pages land structurally with no semantic search, this repo's tracker P1 (TODOS.md NEXT PRIORITY). Nothing in gstack ever recommended ZeroEntropy (the dependency is gbrain-internal), so the gstack side is detection + advisory: the wireup helper warns when ~/.gbrain/config.json names the recipe (fail-open grep — a missing, unreadable, or other-provider config stays silent and never blocks a working setup), the setup-gbrain provider-default comments say never to select the legacy recipe for a new brain, and USING_GBRAIN_WITH_GSTACK.md gains a troubleshooting entry. The gbrain-side provider migration stays open upstream.

Refs #2365

* fix(gbrain-source-wireup): first sync targets the registered source, not --repo

The wireup registered a federated source by id, then ran 'gbrain sync --repo $WORKTREE' — which resolves against the brain's DEFAULT source and (on gbrain 0.46.x) rewrites that source's local_path anchor to our worktree. Net effect: the user's primary knowledge source silently repointed at the gstack brain worktree while the just-registered source got zero pages, and pages_synced still reported success. The sync now targets the registered id ('gbrain sync --source $id', the same form the repo's own troubleshooting documents). Because the script's stated floor is gbrain >= 0.18.0 and nothing proves --source exists there, support is probed via 'gbrain sync --help' first: an older gbrain keeps the wrong-but-working --repo call with an upgrade warning instead of converting it into a hard failure. The probe sits after the GSTACK_BRAIN_NO_SYNC early-exit and is unreachable in --probe mode.

Regression tests (fail on v1.68.3.0): a no-skip sync case asserting the call log shows 'sync --source gstack-brain-<id>' and never 'sync --repo', and an old-gbrain fallback case (fake sync --help without --source) asserting --repo plus the upgrade warning.

Fixes #2662

* fix(setup): --host slate exits informatively instead of silently installing nothing

slate passed --host validation (added to the accept-list in v1.64.1.0) but never got a dispatch arm, and the all-INSTALL_*-zero fallback lives inside the auto branch — so './setup --host slate' configured nothing and exited 0, a silent no-op strictly worse than the original hard rejection. slate is now an informational arm (per docs/designs/SLATE_HOST.md it is blocked on the host-config refactor; Slate reads .claude/skills as a compatibility fallback, so the arm points at './setup --host claude'), and a defensive guard after the dispatch chain errors loudly (naming the host, the missing arm, and the valid targets, exit 1) if a future host is ever accepted without being wired.

Regression tests (fail on v1.68.3.0): a dispatch-arm ratchet asserting every accept-listed install target has a matching dispatch branch — the exact drift class; a registry cross-check deriving both sides from hosts/index.ts and setup's case arms; a behavioral slate probe (exit 0, points at --host claude, never reaches the installer — on unfixed code it fell through into the installer); and a static pin on the guard's shape.

Fixes #2361

* fix(make-pdf): resolve the sibling browse binary from execPath, not argv[0]

In a bun-compiled binary process.argv[0] is the raw invocation string — often relative ('./pdf', 'pdf') — so dirname(argv[0]) yielded '.' and the sibling candidates (../browse/dist/browse etc.) resolved against the CWD instead of the install dir. Resolution was cwd-dependent: correct-by-luck when the fallbacks rescued it, wrong when a cwd-relative path matched. process.execPath is always the absolute binary path. The resolution step takes an injectable selfPath (defaulted) because under bun test the process path is the bun runtime and the compiled-binary shapes are otherwise unreachable.

The issue's other half — pdf setup failing on newtab('about:blank') — was already fixed on main in v1.64.0.0 (browse/src/url-validation.ts exact-match allows about:blank; its comment names this exact smoke). This commit closes what remains.

Regression tests (the sibling-via-selfPath case fails on v1.68.3.0 — pre-fix code ignores the seam and either resolves the global install or throws): sibling resolution from an install-shaped tree, and a decoy-browse-DIRECTORY case pinning that a directory never wins resolution.

Fixes #2156

* fix(memory-ingest): store the normalized git_remote so unattributed pages hit the policy filter

buildTranscriptPage wrote the normalized '_unattributed' sentinel into the page FRONTMATTER but stored the raw resolved remote ('' when unresolvable) on the page object. The policy filter fast-paths !p.git_remote, so under --include-unattributed an explicit '_unattributed → deny' (or read-only) policy never applied to exactly the pages it names — they ingested unpoliced. The stored value now matches the frontmatter.

Regression test (fails on v1.68.3.0): seeds the REAL bin/gstack-gbrain-repo-policy store with '_unattributed → deny' through its own set verb, ingests an unresolvable-remote session with --include-unattributed, and asserts nothing reaches gbrain — pre-fix the '' remote bypassed the filter and the import ran. A fake echoing tiers would pass on both sides of the fix; the real helper prints 'none' for unknown keys, so only a genuinely applied deny distinguishes the two.

Fixes #2353

* fix(land-and-deploy): MERGED recovery reconciles and reports remote-branch cleanup

Step 4's merge commands carry --delete-branch, and the success path tells the user 'The branch has been cleaned up.' When gh exits non-zero AFTER GitHub already merged (routine in worktree layouts: gh's local cleanup runs git checkout <base> and fails), the §4a-postfail MERGED recovery re-established everything EXCEPT the branch deletion — and said nothing about it, so the discrepancy was invisible. The MERGED path now reconciles: git ls-remote --heads distinguishes branch-already-gone (exit 0, empty → 'already cleaned up', idempotent on re-runs) from branch-survived (offer confirm-first deletion, matching the section's worktree posture; -d not -D for any local branch) from check-itself-failed (non-zero exit → 'couldn't verify', skip the offer — never read a failed check as a clean branch).

Template + regenerated SKILL.md + test extensions land in one commit (the md-sync assertion goes red otherwise). Regression assertions (fail on v1.68.3.0: no delete-branch reconciliation existed in test/ at all) pin the ls-remote check, the confirm-first delete, and the absent-vs-failed distinction.

Fixes #2656

* fix(scripts): stop heredoc bodies deadlocking under Homebrew bash

`./setup --help` can hang forever on macOS, printing nothing, with no way
to tell it apart from a slow install. Eleven scripts carry the same
latent hang, `setup` itself being the one every user hits first.

bash 5.2+ delivers a heredoc body of 64KiB or less through a pipe: the
forked child writes the entire body before exec, and nothing reads the
other end until the command starts. Under macOS pipe-KVA pressure the
kernel hands a fresh pipe a 512-byte buffer instead of the usual 16-64KiB,
so any body of 512 bytes or more blocks write() permanently. The capacity
check bash would need to notice (F_GETPIPE_SZ) is Linux-only, so it never
fires here. It is pressure-dependent, which is why it reads as "worked on
my machine" — the same script runs fine all day and then wedges.

Homebrew bash is what `#!/usr/bin/env bash` resolves to on a Mac with brew
on PATH, which is most of them. Apple's /bin/bash 3.2 predates the pipe
path and is unaffected, so the bug is invisible to anyone testing with the
system shell.

The fix is `BASH_COMPAT=50` in each affected script, which restores the
pre-5.2 tempfile path:

    $ bash -c 'probe() { [ -p /dev/stdin ] && echo PIPE || echo TEMPFILE; }
               probe <<EOF
    $(printf "x%.0s" $(seq 1 1000))
    EOF'
    PIPE
    $ BASH_COMPAT=50 bash -c '...same...'
    TEMPFILE

- Not a `#!/bin/bash` shebang swap: that pins the script to whatever bash
  lives at /bin (3.2 on macOS, absent on some Linux distributions) and is
  bypassed entirely by `bash script.sh` call sites. The variable survives
  both.
- Not exported, so child processes keep their own compat level.
- Placed below any `--help` sed range that reads $0, so usage output is
  unchanged (verified on all eleven).
- Every guarded script is bash-3.2-clean — no associative arrays, case
  conversion, or mapfile — so compat level 50 costs them nothing.

test/heredoc-pipe-deadlock.test.ts scans every tracked shell script for a
heredoc body in the 512B-64KiB window and fails without the guard, and
proves the mechanism at runtime on bash 5.2+ by asserting the body moves
from PIPE to TEMPFILE. On older bash the runtime half is skipped, since
the pipe path does not exist there.

Absorbed from PR #2640 with authorship preserved. Wave adaptations: the pipe-probe test skips on minimal-/dev environments without /dev/stdin (it would report OTHER for an unobservable fd), and one caveat verified during review: on bash 4.3/4.4 (e.g. Git Bash), assigning BASH_COMPAT=50 prints a non-fatal 'invalid value' warning to stderr — those bashes are already on tempfiles, so the guard is a no-op there; windows-setup-e2e exercises this empirically.

* docs: TODOS.md v1.69 wave close-out

Move the slate P4 entry and the ZeroEntropy P1's gstack-side half to Completed (v1.69.0.0); reframe the ZeroEntropy NEXT PRIORITY entry around the remaining gbrain-side work; file the wave's four residuals with rationale — the prefixed-cleanup symmetric conversion, the #2163 legacy-slug checkpoint heal, the invited #2657 --reconcile contribution, and the table-driven setup host dispatch behind the new cross-check ratchet.

 		85fd9db554 v1.68.3.0 fix(pairing): re-pair to narrow revokes the old grant on the spot (#2665) 
* fix(pairing): reject reserved clientId 'root' at all token writers

'root' is the sentinel checkScope/checkDomain/checkRate and the server
command gate use for the omnipotent caller, so a scoped token carrying it
bypasses every enforcement path. Add ReservedClientIdError + a shared
assertValidClientId; createToken/createSetupKey throw, restoreRegistry
skips-and-logs (a corrupt state file must not brick boot). /pair and /token
surface it as a named 400, and the CLI fast-fails --client root.

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

* fix(pairing): release tab ownership on revoke

tabOwnership cleared only on tab close, so after DELETE /token a same-name
re-pair inherited the revoked agent's authenticated tabs (own-only access
keys on owner === clientId). Add BrowserManager.releaseClientTabs and run it
unconditionally in DELETE /token (ownership outlives the token, so an
expired-token client can still own tabs); 404 only when both nothing was
revoked and nothing released. Response now carries tabs_released.

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

* v1.68.3.0 fix(pairing): re-pair to narrow revokes the old grant on the spot

POST /pair minted a new setup key but never touched the agent's live
session, so re-pairing --client X --restrict read while X was connected (or
whose 5-min key expired unexchanged) left the original full-access session,
eval included, alive up to 24h.

A reducing re-pair (fewer scopes, tighter domains, lower rate, stricter tab
policy) now revokes the live session and releases its tabs before minting
the new key (grantReducesAccess + revokeClientFully; superseded in the
response). Non-reducing re-pairs keep the session and only drop stale PENDING
setup keys, so a broaden/refresh never strands a working agent and a
narrowing re-pair issued before the agent connects can't leave the old broad
key exchangeable. Revoke happens before mint (revokeToken deletes all of a
client's tokens). CLI prints a version-skew-safe supersede notice and warns
when a re-pair-shaped call omits --client. Docs + CHANGELOG + VERSION.

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

* fix(pairing): harden re-pair per adversarial review

Adversarial review of the diff found four issues, now fixed:
- Validate the requested grant BEFORE the supersede revoke: a reducing
  re-pair with a bad scope/rate no longer destroys the live session and
  then fails to mint a replacement (assertValidTokenOptions runs up front).
- A re-pair with no live session releases tabs orphaned by an expired
  incarnation, closing the tab-inheritance gap /pair had (DELETE /token
  already released unconditionally).
- Test the DELETE /token revoked=0/tabs>0 path and the /pair orphaned-tab
  release at the handler level (HTTP e2e can't, headless owns no tabs).

Garry TanandClaude Fable 5 51932eceef v1.68.2.0 fix: tunnel revoke exists and revokes everything — setup keys included, verified live (#2646) 
* fix(browse): revokeToken deletes ALL tokens for a clientId, not the first Map hit

revokeToken deleted the first Map entry matching the clientId and returned
true. After a normal pairing, two entries share one clientId: the spent setup
key (kept by exchangeSetupKey for idempotent re-exchange) and the session
token, in that insertion order. Revoke ate the setup key, reported success,
and the live session survived: DELETE /token/<id> returned a false 200 while
/agents kept listing the agent. Worse, an unspent setup key created after the
session survived revoke, so a "revoked" agent could POST /connect and mint a
fresh session within the key's 5-minute validity window.

revokeToken now deletes every matching entry and returns the delete count
(truthy-compatible with the old boolean). The DELETE /token handler logs
"Revoked N token(s)" and returns tokens_deleted so the multi-token class
stays visible; revokeSkillToken wraps Boolean() to keep its documented
contract. Regression tests pin shapes a (spent-key shadowing), b (re-grant
hole), c (multiple pending keys), and bystander isolation.

* feat(browse): tunnel revoke/agents CLI with post-revoke verification

`$B tunnel revoke <name>` was documented in the instruction block,
pair-agent/SKILL.md, and REMOTE_BROWSER_ACCESS.md but implemented nowhere:
the CLI forwarded it to the daemon as Unknown command 'tunnel', and nothing
in the repo called DELETE /token/:clientId or GET /agents.

New pre-server short-circuit (#2254 pattern: tokens are memory-only, never
boot a daemon to revoke against it). `tunnel revoke <name>` DELETEs the
token, prints the deleted count ("(count unknown)" for old daemons that
answer {revoked} without tokens_deleted), then RE-READS GET /agents to prove
the agent is gone. The still-listed branch is the version-skew net: a new
CLI against a still-running old daemon with the first-match revoke bug exits
1 and says to re-run (each old-daemon call deletes the next match) or stop.
An alive pid with an unreachable port reports "Could not reach daemon"
(exit 1), never a false "no daemon". `tunnel agents` lists sessions plus
pending (unexchanged) setup keys, which GET /agents now exposes via
listTokens({includeSetup}) — without them the revocation view was blind to
a paired-but-never-connected agent. Setup-key tokens never leave the server.
DELETE /token/ now decodeURIComponents the clientId (400 on malformed
encoding) so CLI-encoded names round-trip.

Tests: subprocess CLI coverage (usage paths, no-daemon exit 0 without
spawning, live pair/connect/revoke loop, pending-key listing), stub-daemon
pins for the skew and unreachable branches, and e2e pins for revoke-all
semantics, percent-encoded ids, and the second-DELETE-is-404 regression.

* fix(browse): CLI always sends explicit pair scopes via shared DEFAULT_PAIR_SCOPES

The effective pairing default lived in two places: the CLI omitted scopes
unless --restrict was passed, and the server filled in its own literal.
handlePairAgent now always sends an explicit scopes list and both sides
reference one exported constant, DEFAULT_PAIR_SCOPES, so the default cannot
silently drift again (pinned by a server-auth source tripwire).

Three input traps closed in the same surface:
- Bare --restrict (or --restrict swallowing the next flag) parsed as "no
  restriction" and silently granted FULL access, the opposite of the user's
  intent. validatePairAgentFlags rejects it pre-server, before any consent
  gate, so an arg error never boots a daemon.
- A scopes list could smuggle the control scope past the explicit flag:
  --restrict "read,control" minted a control-scoped session with no
  --control. /pair now 400s on control in a scopes list without the control
  flag, and the CLI points the user at --control.
- Option typos validated only at exchange time: createSetupKey stored any
  scope string and any rateLimit, so /pair returned 200 with a poisoned
  setup key whose failure surfaced to the REMOTE agent at /connect as a
  misleading "Invalid request body". Shared validation now runs in both
  creators and throws typed InvalidScopeError; /pair and /token 400 with the
  message, naming the bad scope or negative rateLimit. Also
  `opts.rateLimit || 10` became `?? 10` so the documented "0 = unlimited"
  survives the /pair path.

* fix(browse): 403 hint stops recommending --admin; invariant names both scope defaults

The scope-denied hint told restricted agents to "re-pair with --admin for
eval/cookies/storage" — but --admin is a legacy alias for --control, so
following it over-granted browser-wide destructive commands on top of the
admin scope the default already carries. The hint now matches the CLI's
sibling wording: re-pair without --restrict for page access, --control for
browser control.

Registry invariant #2 claimed "admin scope denied by default" three releases
after b73f3644 deliberately made /pair grant admin. It now names BOTH
defaults precisely (registry API functions default read+write; the /pair
ceremony grants DEFAULT_PAIR_SCOPES) so the header cannot lie one layer down.

* docs(pair-agent): document the full-access default, --restrict, and real revocation

The pairing docs still described the pre-b73f3644 model: read+write default,
--admin as the opt-in for JS/cookies/storage. Reality for three releases:
/pair grants read+write+admin+meta (the pairing ceremony is the trust
boundary) and --admin is a legacy alias for --control. A user following the
skill believed they granted a sandboxed session and actually granted JS
execution on their logged-in browser.

pair-agent/SKILL.md.tmpl (SKILL.md regenerated in this commit) now states
the real default, the tunnel-allowlist nuance (eval works remotely; the
js/cookies/storage commands are local-only), --restrict for sandboxed
sessions with an untrusted-content advisory (scope caps prompt-injection
blast radius), and --control for browser-wide ops. "Revoking access"
documents the now-real tunnel revoke (deletes session + pending setup keys,
verifies against the agent list) and tunnel agents, and replaces the
never-implemented `tunnel rotate` with `$B stop` — tokens are memory-only,
so a daemon restart already rotates everything.

REMOTE_BROWSER_ACCESS.md: /connect example shows the real default scopes,
the scope table gains the control row, the 403 hint row matches the new
server wording, and the false claim that /sidebar-chat is on the tunnel
allowlist is gone (TUNNEL_PATHS is /connect + /command; /sidebar-chat no
longer exists in server.ts at all). ARCHITECTURE.md drops the same phantom
endpoint from the allowlist prose and endpoint table.

* v1.68.2.0: revoke-all, real tunnel revoke, truthful pairing docs

Version slot allocated against the live remote via bin/gstack-next-version
(clean patch bump from 1.68.1.0, no collision). CHANGELOG entry covers the
revoke-all fix, the new tunnel revoke/agents CLI, the explicit-scopes wire
contract, and the pairing-docs truth pass.

* fix(browse): adversarial-review hardening — 6 findings fixed, regression-pinned

Pre-push adversarial review (4 lenses, refute-style verification: 13 raw
findings, 7 refuted, 6 confirmed) caught these; each fix carries a pin:

1. --restrict=read (equals form) sailed past validatePairAgentFlags —
   hasFlag/parseFlag are exact-token matches — so the user asked for a
   read-only sandbox and silently got FULL access: the exact failure mode
   this branch claims to close. The equals form is now a hard error before
   any server work.
2. handleTunnel trimmed the agent name but clientIds are stored verbatim,
   so a space-padded agent was unrevocable by the documented kill switch
   (trimmed DELETE 404'd while the grant stayed live). Names now pass
   through verbatim; the live-daemon test revokes ' padded'.
3. The sole pin for "CLI always sends explicit scopes" passed vacuously on
   a simulated revert: toContain('DEFAULT_PAIR_SCOPES') was satisfied by a
   comment. The tripwire now matches the code shape with a regex and bans
   the conditional spread formatting-insensitively.
4. The rewritten 403 scope hint was unpinned — new e2e asserts it names
   --restrict and --control and never --admin.
5. tunnelRevoke's verify-failure and HTTP-error branches and tunnelAgents'
   unreadable-list branch had no coverage — three stub-daemon pins added
   (an unreadable list must never render as "No paired agents").
6. CHANGELOG claimed "40+ new test cases"; the honest count is 35.

Garry TanandClaude Fable 5 9da6692930 v1.68.1.0 fix: phantom AskUserQuestion hooks — canonical-only registration + self-healing settings.json (#2631) 
* fix(settings-hook): KNOWN_HOOKS identity healer — per-item ownership, mutation lock, fail-closed parse

Claude Code strips the unknown _gstack_source key when it rewrites
settings.json, so tag-based dedupe degraded to exact-command equality and
every Conductor worktree's setup appended a fresh hook entry; deleted
worktrees left dead hooks erroring on every AskUserQuestion fire.

- KNOWN_HOOKS identity table (shared JS prelude, single source of truth):
  ownership is intrinsic and PER HOOK ITEM — basename + relpath suffix +
  event (+ matcher where defined). Tags never claim foreign items.
- New `prune-stale [--repoint <root>] [--all]`: prune dead gstack items,
  re-point survivors at the stable install (tag restore from the table),
  exact-duplicate collapse, uninstall/no-team identity sweep. Explicit
  plan_tune_hooks:no is honored (dead pruned, live never re-pointed).
- add-event / remove-source become item-aware: replace/remove only the owned
  item; a user's co-located hook in the same entry is never collateral.
- Mutation safety: mkdir lock with owner token, ownership-checked release,
  atomic stale takeover; per-process-unique tmp + backup names;
  backup-on-change everywhere; fail-closed on parse failure (a corrupt
  settings.json is never overwritten — previously catch{} clobbered it);
  locked atomic rollback.

* feat(gstack-config): `has <key>` — key-presence provenance through STATE_DIR resolution

`get` returns the DEFAULTS value for absent keys, so callers that need to
know whether the USER decided something (vs inherited a default) had no
correct primitive — setup's consent logic was about to grep a hardcoded
~/.gstack/config.yaml, which misclassifies under GSTACK_STATE_ROOT /
GSTACK_HOME / GSTACK_STATE_DIR overrides. `has` exits 0 iff the key is
literally present in the resolved config file, with the same C-locale key
validation as get/set.

* fix(setup): canonical-only hook registration, heal-first, PT_EXPLICIT consent provenance

Three root causes of the phantom-AskUserQuestion-hooks class, all in the
registration path:

- Bug A: the Conductor auto-opt-in upgraded PT_DECISION "prompt" -> "yes"
  even when "prompt" was dev-setup's EXPLICIT --plan-tune-hooks=prompt pin,
  so every new Conductor workspace installed hooks. PT_EXPLICIT (flag/env/
  config-key-presence via `gstack-config has`) now gates the auto-opt-in to
  the true silent fall-through.
- Bug B: hook commands were baked from $SOURCE_GSTACK_DIR (`pwd -P` of the
  running tree — ephemeral for worktrees). Registration is now CANONICAL-ONLY
  via _hook_command_path (${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/gstack);
  missing canonical hook = skip + log, never a baked tree path. SessionStart
  moves to schema-aware add-event under its identity source; whitespace paths
  are quoted.
- Bug C: nothing ever pruned, and dead tagged entries blocked the
  "already installed" guards forever. Setup now heals FIRST on every run
  (prune-stale --repoint at the stable install), surfaces a one-line summary
  only when something changed, surfaces the plan_tune_hooks:no-vs-live-hooks
  contradiction, and --no-team tears down all three sources plus an identity
  sweep for untagged strays.

dev-setup's no-mutation guarantee gains its stated repair exception (prune
dead / re-point existing, never ADD).

* fix(uninstall): run hook cleanup BEFORE install-root deletion + full identity sweep

SETTINGS_HOOK resolves via $(dirname "$0") INSIDE the install root, but the
cleanup ran after `rm -rf ~/.claude/skills/gstack` — a real global uninstall
(running the installed copy) silently no-op'd and orphaned every hook entry.
Tests masked it by running the uninstaller from the repo checkout.

The relocated block also removes the auq-error-fallback source (registered by
setup, previously never torn down) and finishes with a prune-stale --all
identity sweep so untagged strays (Claude Code strips _gstack_source) go too.

* test: phantom-hooks heal coverage — incident facsimile, per-item safety, lock, canonical tripwires

- gstack-settings-hook-schema-aware: 16 new cases — identity re-point (tag
  restore), foreign-basename rejection, mixed-entry per-item safety for
  add-event/remove-source/--all, prune-stale modes incl. bash-prefix +
  Windows-backslash + spaced-path idempotence, duplicate collapse preferring
  the tagged twin, plan_tune_hooks:no split, backup-on-change no-churn,
  fail-closed corrupt-JSON for every mutator, stale-lock takeover,
  fresh-foreign-lock skip, two-writer concurrency smoke, and an INCIDENT
  FACSIMILE replaying the exact 2026-08-17 production damage (6/3/2 entries,
  mixed tags, live-ephemeral Stop) healing to 2/1/1 canonical.
- NEW setup-hook-canonical-paths: static tripwires — canonical-only resolver
  (no $SOURCE_GSTACK_DIR anywhere in it), heal-before-guards ordering,
  unsuppressed heal output, ${VAR:-0} counter idiom, shared-prelude
  concatenation at every bun call site, KNOWN_HOOKS completeness vs setup's
  registrations, uninstall cleanup-before-deletion ordering, defect-class
  warning present.
- setup-plan-tune-hooks-noninteractive: PT_EXPLICIT pins + `gstack-config
  has` provenance + has-subcommand behavior (env-resolution, malformed keys).
- auq-error-fallback-hook: registration + both-teardown wiring (previously
  untested).
- uninstall: behavioral ordering test running the INSTALLED copy from inside
  the root it deletes.
- setup-windows-fallback / gstack-config-key-locale: pins updated for the new
  HOOK_CMD shape and the third C-locale validator.

* fix(test): banner-tripwire exec used JSON.stringify as shell quoting — vacuous pass + stray artifact

JSON escaping is not shell escaping. Interpolating JSON.stringify(script)
into `bash -c ${...}` left every JSON "\n" as a literal backslash-n inside
shell double quotes, collapsing the extracted release-body tripwire block
onto one line: `then\n` parsed as the command word `thenn`, and
`>&2\nelse\n` parsed as the redirect `>&2nelsen` — so every full-suite run
littered a `2nelsen` file (containing "bash: thenn: command not found") in
the repo root, and the test's single not-contains assertion passed
VACUOUSLY because all output had been redirected into that file. The
"and it actually fires" functional check never verified anything.

Fix: pass the script as an argv element (spawnSync array form) and assert
both branches for real — ABORT case must print the leak message to stderr,
clean case must print "banner tripwire clean" to stdout.

Verified: `bun test test/binding-template-drift.test.ts` previously created
the artifact deterministically; the full free suite now runs artifact-free.
The other shell-interpolation sites (evidence, schema-aware concurrency,
empty-find-fallthrough, branch-slug-hygiene) already use correct quoting.

* test: regression pin for legacy remove mixed-entry filtering + ownership negatives

Coverage-audit iron rule: the rewritten legacy `remove` action filters
per-item (pre-v1.67.2 it dropped the whole entry, destroying a user's
co-located SessionStart hook) — modified existing behavior, previously
untested. Also pins two ownership negatives: an owned basename+relpath under
the WRONG matcher stays foreign, and prune-stale on an absent settings file
exits 0 with removed 0.

* fix: pre-landing review fixes — review-army findings hardened

Specialist review (testing, maintainability, security, performance,
data-migration) findings, each verified against code before fixing:

- legacy remove: preserve malformed/foreign entries (hooks absent, non-array,
  or pre-existing empty) — only entries THIS pass emptied are dropped
- add-event: never tag a mixed entry (old gstack versions in sibling
  worktrees treat tags as entry-level ownership and would destroy the user's
  co-located items); tag only single-item entries; prune-stale drops tags
  from mixed entries for the same reason
- prune-stale: within-entry twin collapse (two dead copies of one hook
  re-pointed to the same canonical command no longer double-fire); command
  quoting hardened via gsQuoteCmd (escapes \\ " $ backtick; gsStripWrap
  unescapes so identity round-trips); NUL bytes in the dedupe key replaced
  with a JSON.stringify key (bash silently dropped the NULs, degrading the
  separator; the file also read as binary to tooling)
- gsIsAlive: only provable absence (ENOENT/ENOTDIR) counts as dead —
  EACCES/EIO/unmounted volumes no longer prune (one-way-ratchet guard)
- gsWriteIfChanged: preserves the live settings.json mode across rewrites
  (a user-tightened 0600 carrying API keys was silently broadened to 0644);
  fresh files start 0600; backups rotate (keep 10)
- remove-source: command-less items default to foreign (gstack only writes
  type:command items); single-item stray claim requires a command
- rollback: pointer target must be a sibling settings.json.bak.* file
- uninstall + setup --no-team + SessionStart registration: stderr stays
  attached — a lock give-up or fail-closed parse during TEARDOWN must be
  visible ("the next setup retries" does not apply after uninstall)
- setup: team-mode banner no longer claims an auto-update hook when
  registration was skipped; heal log documents the rollback-pointer caveat;
  SESSION_UPDATE_CMD quoting mirrors gsQuoteCmd; lock constants named
- list-sources: corrupt settings.json reports to stderr instead of silently
  printing nothing (setup guards must not misread corrupt as no-hooks)
- tests: 10 new pins (malformed-entry preservation, mixed no-tag, twin
  collapse, 0600 mode, metachar escaping round-trip, backup rotation,
  rollback pointer refusal, held-lock uninstall warning, matcher-drift
  tripwire, ownership negatives)

* fix: red-team findings — verify-gate identity, single quoting authority, Windows paths

Red-team pass over the hardened diff (several findings empirically verified
by the reviewer before reporting):

- KNOWN_HOOKS gains the sixth identity: gstack-verify-gate (README-documented
  opt-in Stop hook). A tag-stripped verify-gate entry previously survived
  prune-stale --all and errored at the end of EVERY turn after uninstall
  deleted the install root — the exact phantom-hook class this branch fixes.
  Uninstall also sweeps its tagged form.
- add-event is now the single quoting authority: every registered command is
  normalized through the same gsQuoteCmd/gsStripWrap round-trip the healer
  uses. Pre-fix, only SessionStart got caller-side quoting — a spaced/metachar
  canonical root registered broken plan-tune/AUQ/timeline hooks that the very
  next heal rewrote (the codebase disagreed with its own registrations).
- Windows: MSYS-form paths (/c/Users/...) are drive-translated for fs checks
  only (gsWinPath) — native bun resolved them drive-relative, so the heal
  judged every LIVE Windows hook dead and pruned it. The three AskUserQuestion
  hooks and the Stop hook now also get the mandatory 'bash ' prefix on
  Windows (previously only SessionStart did; extensionless bash shims
  otherwise hit the file-association dialog).
- CANONICAL_GSTACK_ROOT falls back to $HOME/.claude/skills/gstack when a
  CLAUDE_CONFIG_DIR-derived root was never installed (the installer hardcodes
  the home path — split-brain left such users permanently hookless).
- prune-stale preserves foreign entries that STARTED empty (they were
  silently deleted, uncounted, on every heal).
- The timeline Stop registration and its list-sources guard join the
  zero-silent-mutations contract (stderr attached).

Tests: verify-gate tag-stripped heal+sweep, started-empty preservation,
add-event quoting-authority round-trip.

* chore: bump version and changelog (v1.68.1.0)

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

* docs: update project documentation for v1.68.1.0

README: document canonical-only hook registration + the prune-stale
self-heal in the setup hooks section; expand the manual-uninstall note
to cover every gstack hook identity, not just timeline-stop-hook.
CONTRIBUTING: record PT_EXPLICIT provenance (Conductor auto-opt-in
fires only on the true silent fall-through) and the heal-first repair
exception in the dev-setup paragraph.

* fix(settings-hook): fail-loud hardening — gsMain umbrella, lock exit 5, prototype-safe ownership

bun in -e mode swallows uncaught exceptions thrown after a require() and
exits 0 (verified on 1.3.13; uncaughtException handlers never fire either),
so any runtime throw in a mutator was a SILENT SUCCESS. Every script body
now runs inside a gsMain try/catch that prints "internal error ... refusing
to mutate" and exits 4.

Also: lock give-up now exits 5 instead of 0 (callers must not report a
skipped mutation as registered); basename lookup uses hasOwnProperty so a
foreign hook named "toString"/"constructor" can't resolve to an inherited
Object.prototype member and abort the sweep; ownership-checked release also
clears an empty/missing owner file; backup rotation sorts by mtime, not
name; Windows-only backslash normalization (a legal Unix path containing a
backslash is no longer rewritten); GSTACK_SWEEP_EXCLUDE_SOURCES lets a
sweep spare named sources; lock tradeoffs documented at the lock helper.

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

* fix(setup): honest hook-registration reporting + verify-gate sweep exclusion

_install_plan_tune_hooks now propagates per-add-event failures (lock
contention exits 5, fail-closed settings errors exit 3) and both caller
sites branch on it: success logs the installed message, failure logs a
visible "NOT registered — re-run ./setup" warning instead of claiming
success for a mutation that never happened.

--no-team's identity sweep runs with GSTACK_SWEEP_EXCLUDE_SOURCES=
verify-gate: turning team mode off must not delete the user-registered
verify-gate opt-in whose binary still exists (uninstall still sweeps it,
correctly, because there the binary itself is being removed).

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

* test: adversarial regression pins — wrong-shape fail-loud, prototype basename, sweep exclusion, lock exit 5

New pins for the fail-loud hardening: a wrong-shape hooks value (object
where an array belongs) exits 4 with "refusing to mutate" and leaves the
file byte-identical (pre-gsMain this was a silent exit-0 no-op); a foreign
hook whose basename collides with Object.prototype ("toString") survives
an --all sweep that still removes gstack rows; GSTACK_SWEEP_EXCLUDE_SOURCES
preserves the verify-gate row during --all; the fresh-foreign-lock test now
asserts the loud exit 5 instead of a quiet skip.

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

* test(verify-gate): allow the --no-team sweep exclusion, keep registration banned

setup now legitimately mentions verify-gate once: the --no-team identity
sweep excludes it via GSTACK_SWEEP_EXCLUDE_SOURCES so team-mode teardown
can't delete a user-registered gate. The opt-in pin tightens from a blanket
not-contains to: every mention must be a comment or that exclusion, and no
mention may sit on an add-event line.

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

* fix(settings-hook): GNU-first stat in the lock stale check — Linux abort on held locks

On Linux, BSD-style `stat -f %m` prints a multi-line FILESYSTEM block to
stdout before exiting 1, so the BSD-first || chain captured that garbage
concatenated with the real `stat -c %Y` epoch. The non-numeric mtime made
`$(( now - mtime ))` a syntax error and set -e killed the binary with
exit 1 whenever a lock dir already existed — every contention path (stale
takeover, give-up, concurrent writers) broke on CI while staying green on
macOS, where BSD stat -f succeeds cleanly.

GNU `stat -c %Y` now goes first (BSD stat rejects -c with no stdout, so
macOS falls through cleanly), and a numeric guard blanks any residual
garbage so a future platform quirk degrades to the normal give-up path
instead of an arithmetic abort. Same defect class as gstack-repo-mode's
GNU-first ordering (#2195). Verified in an oven/bun Linux container:
the four CI-failing lock tests now pass (62/62 across both files).

* test(uninstall): 30s budgets for the two subprocess-heavy behavioral tests

Both tests spawn the copied uninstaller, which itself runs several
settings-hook bun -e children (the lock-contention one also waits out a
300ms give-up per call). On a loaded box those cold starts blow bun's
default 5s per-test timeout, and a timeout kill reports as a bare fail
with no assertion diff — observed at 5.6-8.5s under load avg 25+.
