Summary

Fixes GitHub issue #48 ("token overhead: ~44 KB of identical preamble inlined into all 56 skills), plus the branch's two new skills and supporting fixes.

Preamble carve (the headline) — the runtime-conditional preamble mass (full AskUserQuestion spec, one-time onboarding chain, artifacts-sync rare paths) moved from inlined-in-every-SKILL.md into shared preamble/sections/ files read on demand. Claude-host only; every other harness keeps its full inline preamble. A compact always-loaded AskUserQuestion contract stays inline so a question firing before the full spec loads still renders a compliant brief.

  • Suite 3.50 MB → 2.60 MB (−26%), ~18 KB off every tier-≥2 skill.
  • /autoplan loads each review skill at the start of its own phase (UI/DX scope gates loading, not just running): 421 KB → 84 KB upfront.
  • gstack-config set explain_level now states it is a runtime switch and prints the rebuild command; three terse-gated headings self-describe.
  • Dead v1.0 writing-style migration removed (its gate never fired in production).

New skills (committed earlier on the branch): /autobuilder-loop (drives an approved plan to completion, model-routed subagents per milestone, Docker verification) and /plan-deliverables (turns a plan into per-milestone acceptance criteria the build loop consumes).

Also on the branch: brain-cache F10 fix (local decisions ledger + honest "missing" instead of fabricated-empty), /ship lint+typecheck gate, adversarial-forum retry hardening.

Test Coverage

AI-assessed coverage 65% (above the 60% gate). Gaps were concentrated in new executable bash and the brain-cache F10 path. The two security-critical fixes got dedicated regression tests this ship (test/artifacts-preamble.test.ts, test/gstack-lint-touched.test.ts); toYamlInlineScalar and the autoplan lazy-load structure got unit/structural pins. Remaining gaps (brain-cache F10, skill-check host-aware branch) are filed as P3 follow-ups — the coverage-gen subagents hit the account spend limit before writing them.

Free deterministic suite: 442 files, 6945 tests ran to completion. The daemon test-suite-suicide bug (below) was masking failures in earlier runs; with it fixed the suite runs whole.

Pre-Landing Review

Full pass: 4 specialists (testing, maintainability, security, performance) + checklist + adversarial review. Real issues found and fixed:

  • [CRITICAL, security] Arithmetic-injection via .brain-last-pull fed into $(( )) — the file lives in the git-synced ~/.gstack tree, so a compromised artifacts remote could plant code that runs at the next skill start. Numeric-validated before evaluation, in both the Claude script and the non-Claude inline source. Regression test added.
  • [CRITICAL, security/perf, triple-confirmed] bin/gstack-lint-touched ran unbounded bunx eslint per edit (verified live downloading 166 packages) and executed repo-controlled config. Hardened: repo-local binaries only, no network bunx, fail-open on tool crash/timeout, JSON-first path extraction. Regression test added.
  • [CRITICAL, testing] design/test/daemon.test.ts restored the real process.exit before its armed shutdown timers fired — an assertion failure there killed the whole bun test run with exit 0 and no summary. Drained inside finally; the static no-suicide-exit guard widened to catch every spelling.
  • [security] jq/sed host string could inject fake ARTIFACTS_SYNC status lines into trusted output — sanitized. Regression test added.
  • Informational: double jq/config spawns, (npm run lint || bun run lint) re-run pattern, AUQ format-block duplication (now a shared constant), dead-anchor docs, stale comments — all fixed.

Two items deferred to follow-ups by decision: the lint hook's PostToolUse install (a standing-config change deserving explicit opt-in — hook ships hardened but dormant), and the codex forum member's read-only sandbox flag (unverified on codex review; could break a paid call).

Design Review

No frontend files changed — design review skipped.

Plan Completion

Issue garrytan#48: 4 of 5 fixes delivered (the token-overhead carve). Fix garrytan#5 (repo-file hygiene: CHANGELOG/TODOS/CLAUDE.md size) deliberately deferred to a follow-up PR to keep this diff reviewable. The branch's committed work (autobuilder-loop, plan-deliverables, ship lint gate) has no separate plan file — audited against commit messages.

TODOS

Marked the pre-existing "carve the preamble reference blocks" P3 as done (v1.61.0.0). Filed follow-ups: garrytan#48 fix 5 (repo hygiene, P2), lint-hook install (P3), brain-cache/skill-check regression tests (P3), codex forum read-only sandbox (P4).

Test plan

  • Free deterministic suite runs whole (442 files) after the daemon-suicide fix; carve-affected tests green (parity, size-budget, auq-format, gen-skill-docs, carve-guards, the new bin/config tests).
  • bun run gen:skill-docs --host all --dry-run clean (0 stale) across all 8 hosts.
  • bun run skill:check exits 0.
  • Browser/daemon integration tests (browse/, design/feedback, make-pdf e2e, ios-qa) fail in this headless sandbox for lack of a real Chromium — confirmed pre-existing (identical failure on clean main), not caused by this branch.

* fix(test): eval-list CLI spawns from neutral cwd so slug detection can't dodge the fixture store

getProjectEvalDir() probes cwd-relative .claude/skills/gstack/bin/gstack-slug;
with cwd=ROOT on a dev machine the self-symlink makes it succeed, routing reads
to an empty project-scoped dir instead of the seeded legacy ~/.gstack-dev/evals.
Neutral cwd + absolute script path fails both probes deterministically — same

… community PRs absorbed) (garrytan#2472)

* fix(careful): warn on chained rm even when the last target is safe

The safe-exception block whitelisted rm -rf of build artifacts by
extracting targets with a single greedy match (.*rm ...), which only ever
inspects the LAST rm in the command. A chain like 'rm -rf /; rm -rf
node_modules' was therefore judged solely by its trailing safe target and
allowed without warning, waving through the destructive 'rm -rf /'.

Gate the shortcut to single rm invocations: when any shell separator
(; | & newline, incl. JSON-escaped \n/\r from the grep extraction path)
is present, fall through to the destructive-pattern check, which warns on
any recursive rm. Single-command artifact cleanups still allow.

Adds 3 regression tests covering semicolon and && chains in both orders.

* harden(careful): substitution separators + capital -R recursive flag (garrytan#2039)

Two residual fail-opens in the same guard PR garrytan#2040 hardened, both verified
by executing the script pre-fix:

- rm -rf $(./wipe-all)/node_modules silently allowed: the substitution token
  ends in a whitelisted suffix and the safe-exception early exit skipped ALL
  downstream checks. $( and backtick now count as chain separators; plain
  $VAR expansion stays allowed.
- rm -R / silently allowed: both greps required a lowercase r in the flag
  cluster; capital -R is the documented BSD/macOS recursive flag. Both greps
  now match -[a-zA-Z]*[rR].

Six new tests: substitution x2 -> ask, capital-R x2 -> ask, rm -Rf
node_modules single-command -> still allowed, escaped-newline branch
(existing code, previously untested), and a pinned deliberate FP
(cd app && rm -rf node_modules -> ask) documenting the fail-closed
direction on chains.

* fix(context-restore): prefer the current branch's own checkpoint (garrytan#2052)

All worktrees of a repo share one origin-derived slug, so they share one
`~/.gstack/projects/<slug>/checkpoints/` dir. `/context-restore` loaded the
newest checkpoint across the whole dir, so in one worktree it could silently
restore a *sibling worktree's* newer checkpoint.

Step 1 now orders candidates current-branch-first (read from each file's
`branch:` frontmatter), keeping other branches as a fallback. A branch is
checked out in at most one worktree, so this stops cross-worktree contamination
while preserving Conductor cross-branch handoff: when the current branch has no
checkpoint of its own, the full newest-first set is still used.

- scan the 200 newest before partitioning so a current-branch checkpoint sitting
  below a burst of sibling saves is still found; output still capped at 20
- non-git / detached HEAD / branchless legacy saves fall back to the old
  newest-first behavior (back-compat)
- +5 regression tests in context-save-hardening.test.ts (the garrytan#2052 bug case
  fails on the old pipeline); regenerated SKILL.md + proactive-suggestions.json

Fixes garrytan#2052

* fix(gbrain): pass --confirm-destructive on drift re-register (garrytan#1985)

ensureSourceRegistered() handles match-but-different-path by removing the
old source then re-adding it at the new path. The remove was issued as
`gbrain sources remove <id> --yes`, but gbrain >= 0.42 gates `sources
remove` behind `--confirm-destructive` (`--yes` alone no longer suppresses
the data-loss prompt). The remove therefore fails with "To proceed, pass
--confirm-destructive", which ensureSourceRegistered surfaces as "source
registration failed" — aborting the entire /sync-gbrain code stage for any
already-registered source whose path has drifted. The memory and brain-sync
stages still pass, so the code index silently stops refreshing.

The orchestrator's own safeSourcesRemove() already passes
--confirm-destructive; this brings the lib helper in line with that
convention. Keeps --yes for older gbrain.

Tests: extend the fake gbrain shim in gbrain-sources.test.ts to simulate
the gbrain >= 0.42 guard (remove without --confirm-destructive exits 1),
update the drift re-register assertion, and add a regression test that
proves the drift path no longer throws. Both fail on main with the exact
"To proceed, pass --confirm-destructive" error and pass with the fix.

Fixes garrytan#1985

* harden(gbrain-sources): route drift remove through garrytan#1734 guards + realpath drift check

Absorbing garrytan#2031 un-blocked a destructive remove that bypassed the garrytan#1734
data-loss guards: ensureSourceRegistered's drift path issued
`gbrain sources remove` directly, without the detectAutopilot +
decideSourceRemove checks every other remove routes through via
safeSourcesRemove. gbrain >= 0.42's own prompt was accidentally blocking
that path; with --confirm-destructive passed it is live again.

- Drift remove now refuses LOUDLY (throws, actionable message) while an
  autopilot is active or when decideSourceRemove disallows; a silent
  changed=false would hide the drifted registration.
- decideSourceRemove's extraArgs (--keep-storage when supported) propagate
  to the remove call, matching safeSourcesRemove.
- Drift is realpath-normalized before being declared: a symlink alias of the
  same directory (macOS /tmp -> /private/tmp) is a match, not drift — the
  probable cause of garrytan#1985's reporter hitting the remove on an unmoved repo.
- Drift fires a loud stderr line (old -> new path); perpetual drift in logs
  is the trigger for promoting garrytan#1985's reindex-in-place design.

Tests: autopilot-active refusal (no remove in call log), fail-closed refusal
on unreadable sources list, --keep-storage propagation, symlink-alias
no-drift; existing drift tests pin the guard probes so a live autopilot on
the dev machine can't flip them.

* fix(developer-profile): exclude mode:resources rows from SESSION_COUNT, TIER, NUDGE_ELIGIBLE (garrytan#2067)

Every /office-hours run appends a mode:"resources" bookkeeping row alongside
the real session row, so --read double-counted sessions (~2x): tiers promoted
early and the builder-to-founder nudge armed prematurely. The file already
filtered resources rows for LAST_*/CROSS_PROJECT; the same realSessions
filter now feeds SESSION_COUNT/TIER, and the nudge predicate is the faithful
allowlist (mode === 'builder') so a future mode garrytan#4 fails closed instead of
re-opening this bug.

8 regression tests: count vs resources noise, tier boundaries both sides,
nudge false-with-noise / true-at-3-builders, cross-project trailing row.

Absorbed from PR garrytan#1991 by @mvann (fix + tests commits; the PR's version-bump
commit is superseded by this wave's consolidated release commit).

* fix(hooks): passThrough() two-branch contract — never emit permissionDecision:'defer' (garrytan#2035, garrytan#2006)

Every AskUserQuestion died with "Tool result missing due to internal error"
on current Claude Code builds (Desktop 1.14271.0, CC 2.1.177). Root cause:
the question-preference-hook emitted permissionDecision:'defer' on every
pass-through path. 'defer' is a real PreToolUse value, but since CC v2.1.89
its semantics are "pause this tool call for external resumption" (headless
resume) — never "abstain". Interactive sessions have nothing to resume the
paused call, so the tool orphaned. Pre-2.1.89 builds ignored the unknown
value, which is why the hook worked when it shipped and broke later.

The fix is the two-branch pass-through contract:
- no context -> exit 0 with EXACTLY empty stdout
- memory nuggets present -> hookSpecificOutput with hookEventName +
  additionalContext ONLY (the documented shape; plan-tune Layer 8 memory
  injection ships through this branch and keeps working)

defer() is renamed passThrough() so the function says what it does, and
docs/spikes/claude-code-hook-mutation.md's protocol contract (cited by the
hook header) is corrected in the same commit — it taught '"defer" — let
permission flow continue' and was the reintroduction vector.

Test contract rewritten in the same commit (13 assertions across 3 files,
verified fail-first against the unfixed hook): pass-through paths assert
exact-empty stdout (a garbage/partial write cannot slip past an
optional-chained parse), the nugget path asserts permissionDecision is
ABSENT while additionalContext survives, and a new tripwire asserts no
non-deny path ever puts the string "permissionDecision" on stdout. The
deny (auto-decide) and Conductor prose-redirect paths are unchanged.

Deployment: no migration needed — settings.json points at the absolute
bash shim which execs the .ts live; /gstack-upgrade delivers the fix.

* fix(one-way-doors): unify credential noun net + wire it into the runtime (garrytan#2024)

Library fix: revoke/reset/rotate now share ONE noun alternation (api key,
token, secret, credential, access key, password) with optional plural s?.
Pre-fix leaks: "reset my secret", "reset my access key", "revoke my secret"
(mismatched per-verb lists) and every plural form ("rotate the credentials",
"revoke all tokens" — \b(...)\b cannot match a trailing s).

Runtime wiring — the regexes could never fire in production before:
- gstack-question-preference --check gains --summary-stdin: the question
  text pipes via stdin (never argv — summaries carry quotes/newlines/shell
  metacharacters) and feeds isOneWayDoor alongside the id, so an ad-hoc
  destructive question with a stored never-ask preference now forces
  ASK_NORMALLY. Empty/absent stdin keeps exact id-only semantics.
- question-preference-hook falls back to classifyQuestion(question text)
  when the registry lookup misses, so unregistered destructive questions
  pass through to a human instead of auto-deciding.
- question-tuning resolver prose shows the piped form (SKILL.md regen lands
  in the wave's release commit).

Tripwires (verified fail-first): full verbs x nouns x singular/plural matrix
with the garrytan#2024 repro rows, benign-summary no-over-match rows, stdin
transport survival (quotes/newlines), empty-stdin fail-safe, and hook
fallback both directions (destructive -> pass-through, benign -> deny).

* fix(design): loud integer-flag contract for --count/--retry/--timeout (garrytan#2032)

design variants --count abc silently generated ZERO variants and exited 0:
parseInt(NaN) flowed through Math.min into the generation loop bound. The
same NaN class was live on the two sibling flags in the same file:
--retry abc made generate() a silent no-op (attempt <= NaN never true, null
output, exit 0) and --timeout abc killed the serve board ~immediately
(setTimeout(NaN)).

New design/src/flag-utils.ts: parseIntFlag (pure, unit-testable) +
normalizeIntFlag (CLI wrapper). Contract matches the --viewports precedent
(error loudly on nonsense — these commands spend real image-API money, a
silent fixup hides typos from calling agents): undefined -> default; bare
flag/empty/non-integer ("3.7" rejected, not truncated)/below-min -> exit 1
with usage hint; above-max -> clamp with stderr warning. --count normalizes
at the variants() consumption site so programmatic callers are covered, with
the ceiling derived from STYLE_VARIATIONS.length instead of a magic 7; the
CLI passes the raw flag through (a pre-parseInt would truncate "3.7").

Tripwires live in test/design-flag-utils.test.ts — deliberately under test/,
not design/test/, which is invisible to the bun test glob, TEST_ROOTS, and
every workflow (wiring design/test/ into CI is a captured TODO).

* fix(gbrain): thin-client state — remote-MCP brains no longer classify as broken-config (garrytan#2051)

A thin client (remote-HTTP MCP brain, no local engine by design) probed
`gbrain sources list`, which gbrain's dispatch guard REFUSES on thin clients
(exit 1, no recognized error string), so the classifier fell to its
defensive broken-config default and every suppression gate silently hid
brain-aware blocks from exactly the users on a shared team brain.

New 'thin-client' state, detected PRE-probe from gbrain's own remote_mcp
config marker via the existing gbrainConfigPath() helper (mirrors gbrain's
isThinClient(); honors GBRAIN_HOME; zero network, immune to error-string
drift), with a /thin[- ]client/ stderr backstop in the probe catch. Remote
reachability is deliberately NOT probed by the classifier — that is the
garrytan#1964 pathology; gbrain calls degrade gracefully at use time, and the detect
JSON says so honestly (gbrain_thin_client: {probed: false}).

The state is admitted at every suppression gate — gstack-gbrain-detect
--is-ok (drives setup + gbrain-refresh), gen-skill-docs' detection override,
gstack-config gbrain-refresh — while the sync stages (code/memory/dream)
SKIP with an accurate reason: code indexing runs on the brain server, memory
syncs via the remote brain's artifacts pull. The two consumer classes need
opposite answers, which is why this is a distinct state and not a
skip-the-probe special case. sync-gbrain Step 1.5 and setup-gbrain prose
route thin-client to proceed, never into broken-config remediation.

detectMcpMode secondary generalization: url-match against the config's
remote_mcp.mcp_url (deterministic — gbrain mounts at the generic /mcp path)
-> name pattern gbrain[-_]* -> stdio command token; gbrain_mcp_mode stays a
3-value enum.

Tripwires: end-to-end --is-ok exits 0 on a thin-client fixture AND still
exits 1 on broken-config (the gate didn't widen); pre-probe + stderr-fallback
classifier paths; 4 detectMcpMode identification cases incl. a non-matching
url that must NOT false-positive.

* fix(resolvers): compress --summary-stdin preamble prose to fit parity budget; re-bless ship goldens

The v1.57.7.0 parity suite caps investigate's generated size at 1.09x
baseline; the garrytan#2024 question-tuning prose (duplicated into every tier->=2
skill) tipped it to 1.092. Compressed to a single inline command + short
pointer (the full rationale lives in bin/gstack-question-preference's
header and the one-way-doors module docs). Ship goldens re-blessed against
the final resolver text (conscious template-change acknowledgment, per the
golden-file regression contract).

* fix(e2e): office-hours-spec-review turn budget fits the carved skill layout (garrytan#2473)

The test failed deterministically with error_max_turns at 9 turns on main
and this branch alike (CI attempt logs + local main repro). Root cause from
the failing transcript: the Spec Review Loop content is carved out of
office-hours/SKILL.md into office-hours/sections/, so the agent needs
discovery hops (grep SKILL.md -> ls sections/ -> read the section) before it
can write — 8 tool turns + the closing text turn = 9 > the 8-turn budget,
which predates the carve. Observed failures wrote a CORRECT summary on tool
turn 8 and died on the closing turn.

maxTurns 8 -> 12. Verified: PASS locally post-fix (7 turns this run — the
extra headroom absorbs discovery-path nondeterminism).

* fix(e2e): review-dashboard-via session budget survives runner contention (garrytan#2473)

The test failed on CI (and its baseline run) with the timeout signature:
0 turns, $0.00, exactly 183s, 3/3 attempts — the spawned claude -p session
never emitted a single stream event before the 180s inner timeout. The
file's tests run concurrently on one runner; session startup queues behind
sibling sessions, and this test had the tightest budget in the file (the
240s-budget tests in the same job passed). A clean local run takes 270s
wall for 4 turns, confirming 180s was too tight even without contention.

Inner timeout 180s -> 300s; outer bun timeout 240s -> 360s to keep headroom
over the inner budget. Verified: PASS locally post-fix (4 turns, 270s).

* fix(e2e): retro-base-branch session budget survives runner contention (garrytan#2473)

Same class as review-dashboard-via, one test over in the same file: /retro
is a long multi-step flow whose clean pass measures 225-239s — a coin flip
against the 240s inner budget. First CI run passed at 225s; the rerun timed
out at the 240s line on all 3 attempts (exitReason "timeout"); the local
verification run passed at 239s, ONE second under the old cap.

Inner timeout 240s -> 360s; outer bun timeout 300s -> 480s for headroom.
Verified: PASS locally post-fix (17 turns, 239s).

* fix(evals): align plan-eng/design plan-mode + finding-floor smokes to their declared periodic tier

The garrytan#2077 demotion of these four stochastic tests to 'periodic' was inert:
E2E_TIERS declared periodic but the files self-gated on EVALS_TIER === 'gate',
so they kept running in the blocking gate lane and never in the weekly lane.

Flip the four self-gates to 'periodic' (headers/describe labels updated), add
a free static tier-alignment invariant test (dep-list filename mapping;
unmapped self-gated files are reported, never silently skipped), and name the
two plan-mode test files in their own touchfiles dep lists so the invariant
binds for them.

* feat(pty-runner): scope-gate question/auto-select detectors + observation flags

Two render-shape-anchored detectors (whitespace-squished, like the Pattern-4/5
collapsed-form handling): isScopeGateQuestionVisible requires the question text
PLUS option-body text (native AskUserQuestion renders numbered options, prose
fallback renders lettered — the option body appears in both; narration doesn't),
and isScopeGateAutoSelectVisible requires the announcement prefix PLUS the
selected-B token.

runPlanSkillObservation gains scopeGateQuestionObserved /
scopeGateAutoSelectObserved high-water flags (attached at every return path) so
paid smokes can assert gate behavior across the whole run instead of the lossy
2KB evidence tail. runPlanSkillFloorCheck no longer counts a scope-gate render
toward auqObserved (tail-scoped exclusion) — the floor measures FINDING-driven
questions, and the gate could fire inside the 3s pre-target window.

Unit fixtures pin clean/native/collapsed positives, narration negatives, and
the verbatim template announcement string (template rewording fails here first,
before the paid smokes degrade to vacuous asserts).

* feat(plan-eng/design-review): auto-select B in plan mode at the scope gate

In plan mode the scope gate's "What should I review? A/B/C" question is pure
friction: there is no branch diff and the target is the plan being drafted.
Both gates gain an ordered exceptions block, checked BEFORE asking:

1. Plan mode → auto-select B: review the active plan (in context or pasted),
   announce it in one line ("Scope gate: plan mode — auto-selected B
   (reviewing <target>)") so the user can interrupt; an explicitly different
   user-named target still wins; no plan drafted yet → ask as normal.
2. User-named target (outside plan mode): explicit-only — a path, a pasted
   doc, or the literal words "branch diff". A passing mention is not naming;
   when in doubt, ask.

Outside plan mode with no explicitly-named target, nothing changes. Plan-mode
is checked FIRST because the PTY harness seeds drafts as pasted user messages
(claude-pty-runner.ts:1600) — ordering makes the seeded smokes deterministic.

Pinning: seeded plan-mode smokes assert no gate render + announcement rendered
(eng test 2; new design seeded test); plan-mode-no-op extends to eng/design
(bypass must not misfire outside plan mode; first question must be the gate)
plus a named-target case proving the pasted target is consumed; a drift-guard
asserts the two hand-duplicated exceptions blocks stay identical modulo the
two variant slots and carry the announcement string the detectors pin.

Skeleton ceilings ratcheted with comments (eng 68k, design 89k; eng union
ratio 1.08→1.09) — measured 67,006 B / 88,226 B after regen.

and its section skip list omitted the scope gate — so autoplan ingested a
hard-STOP AskUserQuestion that contradicts its every-question-auto-decides
contract. One skip-list line fixes it; a static toContain pin in
skill-validation keeps the entry load-bearing.

* fix(pty-runner): positional floor exclusion, flag builder, outcome union, token tracking

Review-army + adversarial findings on the scope-gate observability work,
all verified before fixing:

- Floor check: acceptance scanned the CUMULATIVE buffer while the scope-gate
  exclusion scanned only the 1500-byte tail, so an early gate render satisfied
  the floor vacuously once ~1.5KB of output accumulated (found independently
  by 4 review passes; predicate reproduced). Acceptance now scans only content
  APPENDED after the first gate render (positional anchor), and the LLM-judge
  'waiting' shortcut no longer fires while the gate menu is the pending render.
- High-water flags are built once and spread at every return path — the
  hand-spread pattern had already drifted (judge-waiting return omitted two
  flags), which made must-stay-false asserts vacuous on those paths.
- isScopeGateAutoSelectVisible: tense-tolerant selected/selecting/selects
  token (must-be-TRUE asserts shouldn't fail semantically-perfect paraphrases)
  and quoted-occurrence rejection (a model verbatim-quoting the announcement
  while declining must not trip must-stay-FALSE asserts). Fixtures added for
  both directions.
- PlanSkillObservation outcome union gains 'wrote_findings_before_asking'
  (returned at runtime via classifyVisible but missing from the type).
- trackTokens/tokensObserved: cumulative-buffer token high-water for
  consumption asserts (the 2KB evidence tail is lossy and the plan-file
  fallback is unreachable outside plan mode).
- New scope-gate-floor unit pins (from the ship coverage audit): both gate
  render forms trip acceptance and exclusion; a genuine finding AUQ is not
  excluded; tail-scoping semantics pinned.

* test(evals): harden no-op asserts, close tier-invariant fail-open holes, pin gate question strings

- no-op regression: gate-must-ask is now UNCONDITIONAL for eng/design (the
  outcome==='asked' conditional let a silent-bypass plan_ready run sail
  through); eng/design cases force --disallowedTools so the pinned prose
  shape is contractual rather than hoping native AUQ renders match; the
  named-target case uses trackTokens for consumption and lists
  wrote_findings_before_asking in its diagnostic throw branch.
- tier-alignment invariant: both quote styles matched; zero-self-gate,
  mixed-tier, and owning-keys-without-E2E_TIERS-entries are all REPORTED
  instead of silently skipped (the fail-open holes three reviewers found).
- drift-guard: the generated gate menus must carry the exact question/option
  strings the PTY question detector anchors on — free CI fails before the
  paid smokes can go vacuous on a menu reword.
- touchfiles: corrected the no-op cost note for CI concurrency + retry
  semantics.

* fix(ci): register plan-eng/design-review skills in PTY eval containers

The extended plan-mode-no-op smoke invokes /plan-eng-review and
/plan-design-review, but the fresh CI containers registered only
office-hours and plan-ceo-review — both new runs would return
'Unknown command' and fail every PR's gate job (Codex structured
review P1, verified against evals.yml). Registration loops, the
dangling-target fail-fast list, and the frontmatter checks (now a
loop over the same skill list, so the lists can't drift) all cover
the two skills.

* fix(plan-eng/design-review): harden scope-gate exceptions against injection and ambiguity

Adversarial-review wording fixes (Claude adversarial F1-F8 + Codex
cross-confirmation), applied to both gate templates + regen:

- Host-anchored mode signal: only the host's own system messages (plan-mode
  reminder or active plan file path) arm the auto-select; plan-shaped text
  inside pasted documents, tool results, or fetched pages does NOT count —
  injected content can't disarm the consent gate or nominate the target.
- Multiple plan candidates: the host-referenced plan file wins; still
  ambiguous means ask.
- The DIFFERENT-target override carries the passing-mention guard.
- Plan mode + explicitly named target + no drafted plan resolves to the
  named target instead of a contradictory re-ask.
- The numbered ask-path rules are qualified ('When no exception above
  applied:') so they no longer restate an unconditional MUST-ask that
  contradicts the exceptions.
- 'Whenever this gate does ask — in any mode — it is a hard STOP.'
- Shared preamble: 'any AskUserQuestion the skill fires is the workflow
  operating within plan mode' (was 'the first AskUserQuestion is the
  workflow entering plan mode', which framed the opposite of the bypass);
  regenerates every skill.
- Ceilings ratcheted with attribution: plan-eng union ratio 1.10,
  investigate 1.10 (the ~250B shared-preamble reword lands the
  closest-to-ceiling skill at 1.092).

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

* fix(pty-runner): active-render gate veto in the floor check + honest periodic-wiring docs

Codex re-review P2s on the fix wave, both verified:

- A finding AUQ rendering within TAIL_SCAN_BYTES of the gate (model waiting,
  no further output) was vetoed by the blanket tail exclusion until timeout.
  The veto is now ACTIVE-RENDER-aware: parseNumberedOptions anchors the last
  cursor menu, so only a pending GATE menu vetoes; the judge fallback shares
  the same check. Residual (documented): prose gate + prose finding inside
  one tail — floors run the native-menu path in practice.
- The four demoted periodic tests are not in evals-periodic.yml's explicit
  matrix (a named instance of the pre-existing periodic-orphans TODO), so
  they run locally/manually until the PTY-capable periodic job lands.
  CHANGELOG claim softened accordingly; TODO filed with the wiring recipe.

* fix(ship): custom-hooks-path detection false-negatives on git worktrees

The pre-push guard's HOOKS_IN_GIT_DIR check compared the hooks dir against
--absolute-git-dir, which in a linked worktree is .git/worktrees/<name>
while hooks resolve to the COMMON .git/hooks — so every Conductor worktree
read as a 'custom hooks path' and the consented guard install was skipped.
Match against the resolved --git-common-dir too (with a /nonexistent
fallback so a failed resolution can't collapse the case pattern into
match-everything). Verified live: this worktree now reports yes (was no),
and the main checkout still reports yes. Goldens refreshed (--host all).

* fix(evals): give the plan-ceo plan-mode smoke real budget headroom

Measured 2026-08-11: a clean isolated pass took 295.7s against the 300s
inner budget (4s of margin) and the same test timed out at ~308s three
times under concurrent eval load — a budget-edge flake in the gate lane,
not a behavior regression (it passed isolated on both this branch and
main). Inner budget 300s -> 420s, outer bun timeout 360s -> 480s, and the
test file is now named in its own touchfiles dep list so the tier-alignment
invariant binds for it.

* fix(evals): 300s budget floor for the two 90s design-consultation SDK tests

Root cause of PR garrytan#2533's e2e-design CI failure: design-consultation-preview
failed 3 attempts at 0 turns/$0.00/93s — the session was up but the model's
first completion queued past the 90s inner budget under concurrent API load
(11 matrix jobs; the sibling research test booted its first tool at 4s, so
this is API-side queuing, not CPU boot contention). The test was selected
only because touchfiles.ts is a global touchfile; the tested behavior is
untouched by this branch.

90s budgets cannot absorb one slow first completion. Both 90s tests in the
file move to the repo's saturated-runner standard (300s inner / 360s outer,
matching review-dashboard-via and retro-base-branch). Deliberately NOT
re-arming the runner's inner timer on first stream event: an audit found
~100 outer bun-timeout literals sized inner+30-60s that a re-arm would
silently break — the structural options are written up in TODOS.md.

physicalSkillFiles (symlinked dirs included, root router included),
authoredSkills (realpath-deduped, router excluded), registryEntries
(what ./setup registers: unique frontmatter names + _gstack-command).

One counting authority for the hermetic seeder, context-bill ground

* fix(evals): stop the harness grading itself

findPreviousRun excluded only the file being written, by name, so every
suite compared against _partial-e2e.json — the current run's own
accumulator, relabelled with the current tier just before each flush.
That is why every block read '+$0.00, +0s, Stable run, no regressions.'
This harness has never been able to detect a regression, and reassuring
output that cannot fail is worse than none. In-progress runs are now
excluded by role, and a run with nothing to compare against says NO
BASELINE instead of claiming stability.

isPartialEval(data, filename) is the one place that decides what counts
as an in-progress accumulator (the _partial flag OR a _partial-prefixed

that finds the newest real run — scanning the eval dir plus one level of
shards/<slug>/ subdirs, where the sharded paid runner points each
shard's collector. skill-budget-regression.test.ts's hand-rolled
findLatestRun (flag-blind: a flagged-but-renamed accumulator passed its

* feat(evals): register shipped skills for hermetic PTY children

Hermetic children get a config dir that deliberately seeds no skills —
right for children that install their own, fatal for the PTY family that
TYPES /office-hours or /plan-ceo-review: claude rejects the command as
Unknown before any model turn, so the plan-family gate smokes measure
nothing. hermeticSkillsConfigDir() is a second, opt-in config dir under
the same runRoot that mirrors ./setup's registration exactly (real dir
per registry name, SKILL.md + sections/ symlinks, frontmatter-name
resolution, _gstack-command root alias), driven by the shared
skill-census so connect-chrome's dir symlink collapses the same way
setup's idempotent overwrite does.

Ported from fork commit 03c4eca, tree walk rewritten for the upstream
layout (top-level <skill>/SKILL.md dirs, no skills/ tree). Unit tests
are new: seed shape, census parity, symlink resolution, connect-chrome
collapse, idempotence, no-API-key seed.

* feat(evals): seedSkills opt-in for PTY slash-command tests + tripwire

Wire ClaudePtyOptions.seedSkills through launchClaudePty: when set (and
hermetic, and no per-test CLAUDE_CONFIG_DIR override), the child gets
hermeticSkillsConfigDir() so typed /skill slash commands resolve instead
of dying as Unknown command before any model turn. Opted in at the three
runPlanSkill* helpers and the four direct-launch slash-command tests
(plan-design-with-ui, plan-ceo-mode-routing, autoplan-chain,
ship-idempotency).

New static tripwire (test/pty-skill-seeding-wiring.test.ts): any test
file that sends a slash command over the PTY must route through a
runPlanSkill* helper or pass seedSkills: true — an unseeded slash-command
test spends money and measures nothing. hermetic-wiring.test.ts now
blesses the repo-tree seeding path explicitly (config dir under runRoot,
symlinks into the repo checkout, never operator ~/.claude).

The CI "Register gstack skills for PTY smoke" step keeps a keep-me note:
container cross-mount symlinks defeat the TUI scanner and HOME is not
hermeticized, so the real-file copies there must survive this change.

* refactor(evals): single shared paid-test-set module

test/helpers/paid-test-set.ts is now the one definition of which test
files are paid (the exact globs package.json's test:gate expands).
scripts/test-free-shards.ts derives its free/paid exclusion from it
instead of a private regex list, dropping the dead
browse/test/security-review-fullstack.test.ts pattern (file no longer
exists). The sharded paid runner derives its enumeration from the same
module, so a file added to one list can no longer silently miss the
other.

* feat(evals): env-driven lazy eval dir + shard-aware store and tooling

Importing eval-store no longer spawns the gstack-slug subprocess: the
module-level DEFAULT_EVAL_DIR constant is now a memoized defaultEvalDir()
resolved at collector construction. Resolution order: explicit
constructor arg, then GSTACK_EVAL_DIR, then slug detection — so the
sharded paid runner can point each shard child at its own
<evalDir>/shards/<slug>/ dir with plain env, no --preload.

Runs collected under a shards/ subdir record their slug in the eval
JSON (EvalResult.shard). findPreviousRun scans one shards/<slug>/ level
and prefers same-slug priors, so each shard baselines against its own
history instead of whichever shard flushed last. eval:list,
eval:summary, and eval:compare enumerate the same one level of shard
subdirs; eval:compare's no-arg mode also stops picking an in-progress
accumulator as the after-run.

eval-watch stays flat (documented follow-up): it tails a single dir for
live progress and gains nothing from per-shard baselines until the
runner emits a merged stream.

* feat(evals): sharded paid tier runner

scripts/test-paid-shards.ts runs the gate/periodic tier one Bun process
per test file, with an EXTERNAL wall-clock timeout that SIGKILLs the
shard's detached process group and an aggregate that distinguishes
passed / failed / timed-out / never-started — partial execution can no
longer read as a pass. Bun's native --shard/--isolate covers none of
this: no process-group kill (hung claude/codex PTY grandchildren
survive in-process isolation), no never-started taxonomy, no per-shard
env. Each shard child gets GSTACK_EVAL_DIR=<evalDir>/shards/<slug>/
(slug = test filename sans extension, stable across runs) so shard
baselines compare against their own prior runs.

Output classification lives in scripts/test-strict-output.ts (strict
exit-code derivation, incremental fail-line classifier, child signal
forwarding) so the runner and any future strict bun-test wrapper share
one implementation. Enumeration derives from the shared paid-test-set
module; tier exclusion fires only on an explicit whole-file
EVALS_TIER === '<other>' guard.

package.json gains test:gate:sharded / test:periodic:sharded, and
eval:bg:gate / eval:bg:periodic now run the sharded scripts with detach
timeouts sized to the worst case (gate: 49 shards x 30min / 4 jobs ~
6.2h -> 25200s; periodic: 59 -> 28800s).

test/paid-shards.test.ts pins enumeration, tier classification, and the
kill-and-continue property with a real busy-loop shard.

* feat(security): hash-chained egress receipt ledger (core)

Port lib/egress-receipt from the v2 fork as TypeScript: writeReceipt
(sync, fail-closed via typed EGRESS_RECEIPT_FAILED), best-effort
writeOutcome, readLedger/listReceipts/verifyLedger, GSTACK_HOME ->
GSTACK_STATE_DIR -> ~/.gstack resolution, 0600 ledger under a 0700
security dir, and an mkdir spin lock (2.5s budget) with documented
>10s-mtime stale-lock reclaim.

Changes vs the fork:
- lastRawLine tail-reads the final 4KB instead of loading the whole
  ledger, so appends stay O(1) as the file grows.
- WARN-at-size: past 25MB writeReceipt emits one self-explanatory
  stderr warning per process (what the ledger is, how to inspect it,
  rotation TODO); verifyLedger gains a sizeWarning field. Rotation
  TODO carries the chain-genesis sketch (new generation's first record
  embeds the prior file's tail hash).

bin/gstack-egress-receipt is a bun script bridging shell callers:
write|outcome subcommands, exit 3 + EGRESS_RECEIPT_FAILED on stderr on
failure; --no-payload records sha256:null for git-class ops.

* feat(security): shared shell receipt helpers

bin/gstack-egress-lib.sh (sourced library, gstack-gbrain-lib.sh
precedent) provides _receipted_curl and _receipted_git: write the
egress receipt BEFORE the send via gstack-egress-receipt, hand curl the
SAME payload file via --data-binary @file so the receipt hash matches
the wire bytes exactly, then append a best-effort outcome. Per-call
fail policy: 'closed' refuses the send (return 3, problem/cause/fix
message on stderr) and 'open' warns and proceeds. Payload temp files
are consumed immediately per call — no EXIT traps, since callers like
gstack-telemetry-sync own their own EXIT trap and a sourced trap would
clobber it.

Tested end-to-end against a local Bun.serve listener: receipt sha256
equals the sha256 of the bytes the listener received, fail-closed
refusal never touches the network and carries the problem/cause/fix
stderr shape, fail-open warns and proceeds.

* feat(security): receipt core shell sinks

Wire the three core bash egress sinks through gstack-egress-lib.sh:

- gstack-telemetry-sync: the batch POST now writes the payload to a
  temp file, receipts those exact bytes fail-closed, and hands curl the
  SAME file. On refusal nothing is sent and the cursor does not
  advance, so the batch stays buffered for the next run. The HTTP
  status is recorded as the receipt outcome.
- gstack-update-check: fail-open receipts (warn + proceed) on the
  Supabase ping POST, both VERSION curls (via a local
  _receipted_version_fetch helper that skips non-network schemes), and
  git ls-remote. The ping receipt is written inside the backgrounded
  subshell, so it can never block the script's exit.
- gstack-brain-sync: fail-closed git-class receipts. The push receipt
  is written BEFORE the commit consumes the queue, so a refused receipt
  leaves the queue intact and the next run retries the whole drain
  (pinned by a new queue-intact-on-refusal test, including the
  problem/cause/fix refusal message shape). The retry-path fetch and
  retry push carry their own fail-closed receipts.

* feat(security): receipt TS module sinks + tunnel

writeReceipt (fail-closed, sha256:null — a subprocess or SDK owns the
wire bytes) before every TS-module network-bearing operation:

- bin/gstack-gbrain-sync.ts: before the gbrain code walk that ships
  repo content to the user's gbrain DB (may be remote Postgres). A
  refused receipt fails the stage with status refused-egress-receipt.
- bin/gstack-memory-ingest.ts: before the gbrain batch import of
  transcript pages. A refused receipt returns a system_error verdict
  without spawning the import.
- browse/src/server.ts: before both ngrok.forward call sites (start-up
  BROWSE_TUNNEL=1 path and the /tunnel/start endpoint). A receipt
  failure lands in the existing catch that tears the tunnel listener
  back down and refuses the start.

* feat(design): receipted fetch for OpenAI calls

design/src/receipted-fetch.ts wraps every api.openai.com call: a
content-free egress receipt (sink design-openai, sha256 of the JSON
body — hash only, never the body) is written BEFORE the send. Polarity
is FAIL-OPEN: user-facing generation must not die because an audit log
hiccuped, so a receipt failure warns on stderr and the call proceeds.
Streams pass through untouched (response bodies returned as-is;
non-string request bodies receipted as sha256:null rather than drained
to hash).

All ten call sites converted with per-command payload classes:
generate, variants (injected fetchFn passes through), iterate (both
threaded and fresh paths), evolve (image + screenshot analysis), check,
diff, design-to-code, memory.

Unit-tested with injected fetch: receipt-before-send ordering, stream
passthrough, and fail-open on an unwritable ledger.

* feat(security): receipt admin scripts + user git-ops (zero exceptions)

Wire the remaining shell egress through gstack-egress-lib.sh:

- gstack-gbrain-mcp-verify: both JSON-RPC probe POSTs (initialize +
  tools/list) receipted fail-closed via payload files (hash == wire
  bytes). A refused receipt lands in the NETWORK class — no send.
- gstack-security-dashboard / gstack-community-dashboard: the
  community-pulse GETs receipted fail-open (read-only stats must not
  break over an audit hiccup).
- gstack-gbrain-supabase-provision: api_call receipted fail-closed.
  Each retry attempt hands the helper a fresh copy of the body file
  (the helper consumes its payload). The receipt hashes the request
  body only — the PAT never reaches the ledger or any log. Refusal
  exits 8 without retrying.
- git-class sha256:null receipts, fail-open: gstack-artifacts-init
  (ls-remote, initial push, fetch/pull recovery, retry push),
  gstack-brain-restore (staging clone, existing-repo fetch),
  gstack-session-update (self-update pull).

gstack-team-init needs no wiring: every git clone in it is inside an
echoed instruction string, not an executed command.

The lib now self-locates with shell builtins only (no dirname), so
sourcing works under the whitelist-PATH test harnesses.

Static-grep tripwire pinning the egress-receipt wiring (threat model in
the header: the ledger is forensic observability of ATTEMPTED egress,
not an exfiltration control):

- Per-sink assertions: every wired TS module imports egress-receipt and
  calls writeReceipt; every wired shell sink sources
  gstack-egress-lib.sh with each network op under a receipt;
  ngrok-proximity check for server.ts; every design api.openai.com call
  routes through receiptedFetch.
- Absence assertions: the dead brain-consumer/reader scripts stay
  deleted (lstat, so a dangling symlink also fails).
- Polarity table pinned as data (fail-closed: brain-sync,
  memory-ingest, gbrain-sync, telemetry-sync, ngrok, mcp-verify,
  supabase-provision; fail-open: design-openai, update-check,
  dashboards, git-class user ops, context-bill --exact) plus per-file
  polarity spot-checks.
- NEW-SINK SCANNER with zero KNOWN_UNWIRED: sweeps bin/, lib/,
  scripts/, design/src, browse/src for curl, absolute-URL fetch(, and
  git remote ops (never local rev-parse/get-url; heredoc bodies and
  message strings excluded) and requires every hit to be receipted or
  in a REASONED exemption list where each entry carries its why.
  Preamble-generated skill prose documented out-of-scope in the header.

* feat(cli): context-bill — token bill-of-materials (stripped port)

lib/context-bill.ts, ported from the v2 fork and STRIPPED to the tiers
this repo's skills can exercise: ALWAYS-ON (per-skill frontmatter bytes
with dead-key and foreign-host-file flags), EAGER (SKILL.md + any
forced 'for every invocation' references), on-disk totals, --diff,
--budget, and --exact with the calibration table. The fork's
CONDITIONAL/TRANSITIVE/LAZY/FAST-PATH parsers understand only its
dispatcher layout and were dropped; the tier fields stay in the report
shape (empty/zero/null) so re-adding a parser is additive.
TOKEN_DIVISORS and their provenance docblock kept; --help notes
recalibration via --exact's calibration block.

Three upstream fixes over the fork:
(a) findSkillDirs treats the walk ROOT as a container — the repo root's
    router SKILL.md is billed AND its children are walked (the fork
    short-circuited and billed one skill); walkMd skips node_modules
    and dot-directories.
(b) installed-tree layout: subdirs that are their own repo checkout
    (a gstack/ clone inside ~/.claude/skills, detected by .git) are
    skipped, and directory symlinks (connect-chrome) are followed with
    a container-recursion cycle guard.
(c) ROUTER_KEYS widened to the upstream frontmatter contract {name,
    description, version, allowed-tools, triggers, preamble-tier}.

--exact writes an egress receipt (sink context-bill-exact, host
api.anthropic.com) BEFORE any count_tokens POST; if the receipt cannot
be written the run degrades to the offline estimate with a warning —
nothing is sent unrecorded. bin/gstack-context-bill is the bun shim.

Tests: fixture-tree ledgers, the three fixes, --diff/--budget exit
codes, --exact with injected fetch (envelope subtraction, receipt
ordering, fail-open degradation), CLI smoke test, and ground truth
against THIS repo via test/helpers/skill-census.ts.

* test(catalog): aggregate discovery-surface budget with ratchet protocol

Every host loads every skill's frontmatter name + description at
discovery, every session. applyCatalogTrim in scripts/gen-skill-docs.ts
shapes each description and the 160KB per-file warn covers body size,
but nothing capped the aggregate frontmatter — the catalog could grow
one reasonable-looking description at a time. This test is that
enforcement layer.

Measures the catalog via test/helpers/skill-census.ts authoredSkills
(symlink-deduped, root router counted separately as the _gstack-command
alias line item): 53 skills + router = 4,420 bytes = 1,105
token-equivalents today, asserted <= 1,150 (~4% headroom). Per-skill
sub-cap of 260 bytes (largest today: design-consultation at 229), plus
a non-empty-description check.

Failure messages are self-service ratchets: they print the new total,
the delta, and the update protocol (bump the constant AND the
derivation comment in the same commit; trim instead of grow for
existing descriptions). Parser handles folded block scalars
(description: >-) for fork parity; import-free by design so it
survives generator refactors.

* fix(browse): extension token bootstrap moves to pinned-origin POST; /health carries no token

GET /health is now liveness/status only in every mode — both token
carve-outs (headed-mode disjunct AND chrome-extension:// Origin
disjunct) are removed. Token bootstrap is POST /extension-token on the
local listener: the Origin header must be exactly
chrome-extension://<GSTACK_EXTENSION_ID> and the Host header's hostname
must parse to 127.0.0.1 or localhost (parsed via new URL, never literal
equality — Host arrives as '127.0.0.1:34567'). Wrong origin/host → 403
with no detail. The tunnel surface 404s the endpoint (not in
TUNNEL_PATHS, verified by test).

The extension ID is pinned by a new "key" field (RSA public key) in
extension/manifest.json; browse/scripts/extension-id.ts reproduces the
ID derivation (first 16 bytes of SHA-256 of the DER public key, hex
mapped 0-9a-f → a-p). The private key is not committed anywhere —
unpacked/baked-in loads only need the public key.

Extension side: background.js bootstraps and refreshes the token via
POST /extension-token (403 → disconnected state); sidepanel.js direct
connect path does the same; sidepanel-terminal.js's dead /health token
fallback (read AUTH_TOKEN/authToken keys the server never sent,
hardcoded port) is replaced with the window.gstackAuthToken path.

MIGRATION NOTE: the manifest key pins the extension ID, so existing
installs' side-panel local state (saved port, snoozes) resets once —
explained in-product via a one-time notice (flag
gstack_id_migrated_v162). After upgrading the server, restart the
browser so the old service worker stops polling for a token GET /health
no longer serves.

* docs: correct stale compiled-binaries claim; file three egress/eval follow-ups

CLAUDE.md's compiled-binaries section claimed browse/dist binaries are
tracked by git and appear as modified in git status — false since
64d5a3e (v0.11.16.0) untracked them, and actively harmful: it trained
agents to ignore dist binaries in git status. The section now states
the truth (untracked + gitignored; a dist binary in git status means
someone force-added it) and covers make-pdf/dist too.

TODOS.md gains the three follow-ups filed by the v1.62 port-wave
reviews: ledger rotation with chain-genesis records, launch-nonce
token bootstrap, and eval-watch shard-awareness.

* fix: pre-landing review fixes for the v2 port wave

Review army (checklist + 5 specialists) + coverage/plan audits on the
assembled branch. Genuine correctness/security/hygiene fixes:

- test-paid-shards: strictTestExitCode now receives expectedFiles on the
  real bun path, so a shard that runs fewer files than planned (harness
  crash, nothing loaded) with exit 0 is no longer recorded 'passed' — the
  invisible-non-execution class the runner exists to kill. Pinned by the
  new test/strict-output.test.ts (also covers the chunk-boundary classifier).
- test-paid-shards: EVALS_TIER env is validated (gate|periodic) like the
  --tier flag, so a typo can't self-skip every test and exit 0 green.
- package.json: test:periodic:sharded sets EVALS_ALL=1, restoring the
  full-tier semantics the pre-shard script had (CI already set it; local
  eval:bg:periodic silently under-measured without it).
- brain-sync.test: run() pins HOME to the temp home so gstack-artifacts-init
  stops writing/clobbering the operator's real ~/.gstack-artifacts-remote.txt
  every free-suite run; afterEach now also scrubs the current filename.
- egress-receipt: cap each receipt field at 512B so a serialized line always
  fits the 4KB tail-read window — a longer line would make the next append
  hash a truncated prior line and verifyLedger report a permanent false
  TAMPER. warnLedgerSize short-circuits before statSync once fired (append
  hot path).
- gstack-egress: import.meta.dir (Windows-safe) instead of new URL().pathname
  so grants doesn't silently report defaults on Windows; strip control chars
  from ledger-derived fields on render so a crafted receipt can't spoof the
  auditor's view.
- extension/background.js + CLAUDE.md: renumber the identity-pin migration
  refs v1.62 -> v1.63 (main claimed 1.62.0.0; this wave queue-advances).
- egress-receipt-wiring: pin lib/context-bill.ts unconditionally (both land
  together now); drop the dead RunShardsOptions.tier field.

All fix-affected test files green; gate failures triaged as external-env
(codex/gemini CLI drift) or pre-existing (hermetic-canary fails identically
on base). Deferred polish tracked in the PR body + decision store.

* docs: file TODO to harden plan-design-with-ui PTY detection

The v1.63 seedSkills change made this gate test execute for the first

(correctly-rendered) scope-gate AskUserQuestion out of a spinner-mangled
PTY buffer. Shipped skill behavior is correct — test-harness limitation.

* chore: re-slot release as v1.62.1.0 (PATCH per user)

Main claimed 1.62.0.0 while the wave was in flight; the user chose the
PATCH slot over queue-advancing MINOR. Renumbers the identity-pin
migration notice (now version-free flag name so a re-slot never orphans
an already-set flag), the CLAUDE.md /health note, the CHANGELOG heading,
and the TODOS section titles.

* fix(test): stop hard-requiring the literal ok) case label in gbrain-refresh guards

The extractor grepped for 'ok)' but the case label grew to
ok|timeout|thin-client) (garrytan#1964, garrytan#2051), so the whole file errored on
import — the free suite's only red for months. The extractor now matches
any label starting with ok and its alternations; all 7 guard assertions
run again.

* fix(test): hermetic-canary probes with ${VAR:-} so nounset shells can't fail success

The probe echoed bare $CONDUCTOR_WORKSPACE_PATH — when scrubbing WORKS
the var is unset, and under a nounset shell the echo errors, failing the
canary exactly when isolation succeeds. Defaulted expansions assert
identically under any shell. Fails identically on base; fixed here.

* fix(evals): absorb codex/gemini CLI drift; external-service tests go periodic-tier

- codex exec gains --skip-git-repo-check: newer CLIs refuse exec in an
  untrusted non-git dir (our temp skill dirs) — empirically verified.
- gemini: --skip-trust was removed in gemini-cli 0.34 (argv parse error);
  dropped from the session runner and the benchmark adapter. A present-
  but-unusable CLI (deprecated individual code-assist auth path) now
  classifies as SKIP, not a false adapter failure; the benchmark live
  smoke skips on auth/rate_limit error codes (environmental) while still
  failing on timeout/unknown (the drift classes it exists to catch).
- codex-e2e, gemini-e2e, and benchmark-providers gain the canonical
  whole-file EVALS_TIER === 'periodic' guard per CLAUDE.md tiering rule 3
  (external service -> periodic) — the sharded gate runner now excludes
  all three (gate: 45 -> 42 shards).

* fix(evals): parse single-logical-line AskUserQuestions in the PTY runner

When the PTY reflows a boxed AUQ, ALL options land on ONE logical line
after stripAnsi — parseNumberedOptions parsed one option per line, found
only '1.', and the >=2 check failed forever while the correct question
sat on screen (plan-design-with-ui timed out this way twice, with the
rendered scope-gate AUQ visible in both failure buffers). The cursor
line is now parsed as a stream of ascending N. tokens; DEC cursor-
visibility residue is stripped before matching; plan-design-with-ui's
budgets grow to fit observed ~6min preamble+thinking latency. Pinned by
test/pty-auq-single-line.test.ts using the real failure buffers; all 142
existing parser-consumer unit tests still green.

* chore: restore v1.63.0.0 (MINOR — user-confirmed final slot)

The wave ships new capability (egress receipts + two CLIs, sharded paid
runner, hermetic skill seeding) at ~8K lines — MINOR scale per the
scale-aware bump rules. Supersedes the brief v1.62.1.0 re-slot; the
version-free migration flag means no state churn from the renumber.

AskUserQuestion in full in filenames, identifiers, and comments.

* docs: sync every doc surface with the v1.63 release

/document-release audit (4-lane, all claims verified against branch code):

- README: gstack-egress + gstack-context-bill rows in the standalone-binaries
  table; Privacy & Telemetry gains the receipted-egress bullet (attempted-
  egress framing per the shipped threat model).
- ARCHITECTURE: /health is liveness-only, POST /extension-token endpoint row
  + bootstrap mechanics paragraph; new Egress receipt ledger subsection under
  Security model; eval persistence covers the sharded runner, GSTACK_EVAL_DIR,
  and the finalized-run baseline rule.
- CLAUDE.md: sharded test scripts in Commands; sharded semantics in the
  detached-evals section; PTY skill seeding in the hermetic section; egress
  invariant block beside the other server-egress invariants; catalog-budget
  ceiling beside the 160KB token ceiling; project-tree entries for
  lib/egress-receipt.ts, lib/context-bill.ts, scripts/test-paid-shards.ts.
- CONTRIBUTING: seedSkills + live-tree seeding in the hermetic paragraph;
  sharded runner in detached runs; catalog-budget in the Tier 1 list.
- BROWSER: extension token bootstrap section, tunnel egress receipts section,
  identity-pin migration note in manual install.
- REMOTE_BROWSER_ACCESS: tunnel-start receipt bullet in the security model.
- gbrain docs: /sync-gbrain + brain-sync egress-receipt behavior documented;
  dead consumer-token instructions removed (consumer machinery deleted this
  release); new fail-closed refusal added to the error catalog.
- CHANGELOG: measured-vs-ceiling catalog numbers, contributor notes for the
  external-service tier move and the PTY single-line AskUserQuestion parser,
  release date.
- TODOS: /health token-distribution TODO resolved by this release, removed;
  port-wave follow-up sections re-labeled to the shipped version.

* docs: sweep drift that predates this release

Surfaced by the /document-release audit; every fix verified against the
current binaries:

- gstack-brain-init was replaced by gstack-artifacts-init in v1.27.0.0
  (hard-delete, no compat shim), but README, USING_GBRAIN_WITH_GSTACK,
  docs/gbrain-sync.md, and docs/gbrain-sync-errors.md still instructed
  users to run it — command-not-found on every follow. Same sweep updates
  ~/.gstack-brain-remote.txt to the canonical ~/.gstack-artifacts-remote.txt
  (legacy name still honored on restore, noted where users copy the file).
- gbrain-sync-errors.md headings re-matched to the literal messages the
  binaries print today (the doc's whole value is grep-by-exact-message):
  'gstack-artifacts-init: ~/.gstack/ is already a git repo pointing at:',
  'Remote not reachable via SSH:', 'Failed to create or find ...'. The
  already-a-repo fix now leads with the command's own set-url suggestion.
- docs/gbrain-sync.md 'Under the hood' linked a plan file that does not
  exist in the repo; replaced with the decisions themselves.
- SIDEBAR_MESSAGE_FLOW startup timeline: /pty-session responds with
  {terminalPort, sessionId, attachToken, leaseExpiresAt} (v1.44 shape,
  verified at browse/src/server.ts:1860), not the retired
  {terminalPort, ptySessionToken} pair.

* docs: fold the Codex accuracy review of the release docs

Six findings, all verified against source before fixing:

1. 'Every send writes a receipt' overclaimed — fail-open sinks proceed with
   a stderr warning when the receipt write fails, so a fail-open send can go
   unrecorded (lib/egress-receipt.ts:8-14). Descriptive prose now says so;
   the receipted framing keeps 'attempted'.
2. 'Receipts hash the request body' is wrong for subprocess-owned sends —
   git pushes record sha256: null (lib/egress-receipt.ts:71).
3. 'grants shows every consent in force' overclaimed — it reports the four
   standing config settings (bin/gstack-egress:139-181). Reworded in
   README, ARCHITECTURE, and the CHANGELOG entry.
4. 'Zero-exception scanner' vs reality: the new-sink scanner carries a
   reasoned SCANNER_EXEMPT list (user-directed fetches, probes, instruction
   strings, skill prose). CLAUDE.md now names it.
5. Error-catalog cause/fix for the receipt refusal: the writer mkdirs the
   ledger dir itself, so 'missing' isn't a cause and bare chmod fails when
   it is absent — cause reworded, fix is mkdir -p && chmod.
6. gbrain-sync first-run steps described the retired binary's behavior:
   default repo is gstack-artifacts-$USER, and init PRINTS the gbrain
   hookup command (never auto-executes; bin/gstack-artifacts-init:384-419).

* fix(hooks): nest freeze/careful permissionDecision under hookSpecificOutput

Claude Code ignores a top-level permissionDecision, so the /freeze deny and
/careful ask guards silently allowed everything. Nest both under
hookSpecificOutput with permissionDecisionReason, update the shape-blind
tests to pin the nested form, and document the constraint in both skill
templates (regen included).

Closes half of #1459 (freeze enforcement chain).

* fix(team-init): required-mode hook blocks with nested schema + exit 2

The generated check-gstack.sh emitted a flat permissionDecision payload and
exited 0, which Claude Code ignores — required mode enforced nothing. The
generated hook now nests the deny under hookSpecificOutput and exits 2 so
the block holds even if the JSON schema drifts again. Adds a temp-repo
regression test that runs the generated hook under both installed and
missing-gstack homes.

* fix(careful): close three check-careful bypasses via real JSON extraction

The grep-based command extractor stopped at the first escaped quote, so any
quoted argument truncated the command before the pattern checks ran —
`git commit -m "wip" && rm -rf /` was silently allowed. Replace it with a
python3/node JSON parse that fails CLOSED on unreadable payloads, add an
IFS/base64-to-shell obfuscation tripwire, and stop multi-line commands from
riding the single-line safe-exception whitelist (line-based grep would have
approved `rm -rf /` when a later line matched node_modules — a hazard the
real newline decoding exposed).

Contributed by @wtamminga (PR #2426; the -R hunk was dropped — it landed in
v1.61.0.0 — and output shapes updated to the nested hookSpecificOutput form).

* fix(review,autoplan): require explicit run_in_background: false on specialist agents

Claude Code v2.1.198 made subagents run in the background by default, which
inverted the old "do not use the flag" guidance: review-army specialists and
autoplan dual voices silently launched in the background and the merge step
could proceed before they completed — regressing the #497 fix. The generated
guidance now instructs an explicit run_in_background: false, and a static
tripwire fails the free suite if the inert inverted phrasing ever returns to
any generated SKILL.md.

Fixes #2440.

* fix(investigate): anchor the scope-lock freeze hook on $HOME, not CLAUDE_SKILL_DIR

The investigate skill's PreToolUse hooks and Scope Lock probe resolved
check-freeze.sh via ${CLAUDE_SKILL_DIR}, which does not exist when
frontmatter hooks run — the || exit 0 tail then failed open, so the debug
scope boundary silently never engaged (#1871 follow-up). Anchor all four
sites on $HOME/.claude/skills/gstack/ like careful/freeze, and add a static
test asserting no frontmatter command: line in the guard-family skills ever
references CLAUDE_SKILL_DIR again.

Fixes #2469; closes the last live half of #1459 together with the
freeze/careful hookSpecificOutput fix. The broader portable-install-root
rewrite stays #1882 (its own focused PR per the TODOS.md decision).

* fix(redact): scan large diffs in line-aligned slices; stop digit-UUIDs matching as cards/phones

The prepush guard blocked any push whose added lines exceeded the engine's
1 MiB cap with engine.input_too_large — a size error naming no credential —
which trains people onto GSTACK_REDACT_PREPUSH=skip. Scan in 768 KiB
line-aligned slices instead (no pattern is multi-line, so a boundary cannot
bisect a secret); a single oversized line still goes to the engine intact and
fails closed. Also suppress card/phone matches whose span sits ENTIRELY
inside a UUID — digit-only UUID fixtures were 14 of 21 MEDIUM findings on an
ordinary branch, the noise level that stops people reading MEDIUM at all.

* fix(redact-prepush): resolve the real push base instead of EMPTY_TREE whole-repo scans

When the remote default branch is not main/master (or origin/HEAD is unset),
the merge-base guess failed and the hook fell back to scanning the ENTIRE
repository as added lines — re-attributing long-pushed secrets to the
current push and, on any real repo, tripping the engine byte cap so the push
blocked having scanned nothing. Derive the base from commits reachable from
no remote-tracking branch, keep the empty-tree path only for genuinely fresh
repos, and split the block message so an unscannable diff is reported as
"could not scan (fail closed)" rather than "credential found — rotate it".

* fix(redact-prepush): preserve the trailing newline handed to chained pre-push.local

The chaining wrapper captured stdin with $(cat), which strips the trailing
newline — a chained shell hook built on `while read` then never entered its

the printf-x sentinel so the byte-exact input reaches the chained hook, with
tests covering both the pass-through and the short-circuit paths.

* fix(redact-prepush): close the ext-diff, header-lookalike, and ref-parse bypasses

Three ways the pushed diff escaped scanning: (1) a user-level diff.external
or textconv driver replaced the diff with its own output — zero '+' lines,
so the scan saw nothing (now --no-ext-diff --no-textconv); (2) an added
content line whose text begins with "++" renders as "+++…" and the blanket
header skip dropped it (now hunk-aware header detection); (3) a pre-push
ref line that failed to parse was silently skipped, leaving that ref
unscanned (now fails closed with the offending line named).

Minimal reimplementation of the two confirmed bypasses from PR #2498 by
@lubosxyz (the full PR overlaps the chunked-scan work absorbed separately),
plus the unparseable-ref hardening.

* fix(pair-agent): keep the ngrok authtoken out of the transcript and shell argv

The not-authed flow told the user to paste their ngrok authtoken into the
chat so the agent could run `ngrok config add-authtoken` — putting a live
credential in the transcript, tool-call argv, and anything the transcript
syncs to. The user now runs the auth command in their own terminal; the
agent only verifies via `ngrok config check`, and a pasted token triggers a
rotate-and-reauth instruction. A static test pins that no agent-run bash
fence ever contains add-authtoken again.

* fix(update-check): crash emits CHECK_FAILED instead of reading as up-to-date

gstack-update-check signals "up to date" with SILENCE, and it runs under
set -e — so any unguarded mid-script failure exited quietly and was
indistinguishable from a current install. Observed live as a 45-release
silent-staleness incident. An ERR trap (with -E so it propagates into
functions) now emits a CHECK_FAILED sentinel naming the line and status,
and exits 0 so caller `|| true` guards can't eat it. Behavioral tests cover
both the crash and the healthy-silent paths; egress-receipt wiring is
untouched and still pinned by test/egress-receipt-wiring.test.ts.

Fixes #1974. (#2378's HEAD-SHA staleness half was already fixed on main by
the ls-remote + SHA-pinned VERSION resolution — close as already-fixed.)

* fix(extension): deny token/port reads to content-script and foreign senders

background.js answered getPort — port, connected state, AND the browse
server auth token — to any sender that passed the type allowlist,
including content scripts running in web-page context and, behind only
the sender.id check, anything without extension-page provenance. The
getToken sender.tab restriction covered getToken alone, and only after
getPort had already handed out the token.

Single decision point now: extension/sender-auth.js classifies each
message type; the eight privileged types (getPort, setPort, getServerUrl,
getToken, fetchRefs, command, sidebar-command, getTabState) require an
own-extension-page sender (chrome-extension://<own id>/ URL, no
sender.tab, own sender.id). Denied senders get { error: 'unauthorized' }
and nothing else — never the token, never the port. Content-script flows
(elementPicked, pickerCancelled, inspectResult, openSidePanel) are
untouched, and the sidepanel/popup keep the getPort token field their
connect path reads. The policy mirrors the v1.63 server-side model:
AUTH_TOKEN is released only to the pinned extension Origin via
POST /extension-token, so the extension must not re-leak it to contexts
the server would never have trusted.

browse/test/extension-sender-auth.test.ts drives the real background.js
onMessage listener under a chrome stub with four sender shapes (own
extension page, own content script, foreign extension id, missing
sender.url) and pins that denied responses carry no token/port fields,
that a denied setPort never persists, that a denied command never
reaches the network, and that the inspector + tab-state flows keep
working. The helper is loaded via importScripts in the classic service
worker and require()-able from bun tests.

* test(update-check): fixture links gstack-egress-lib.sh — all 38 tests failed on main

v1.63.0.0 made bin/gstack-update-check source bin/gstack-egress-lib.sh
unconditionally, but the test fixture's GSTACK_DIR only linked gstack-config
— every test died at the source line (0/38 pass on pristine main,
verified). The suite-truncation bug hid it: the runner was killed by an
earlier file's delayed process.exit before this file ran. Link the lib like
the real install layout the script assumes.

* fix(browse): capture active-tab state before close() — last-tab auto-create raced the close event

closeTab checked `tabId === this.activeTabId` AFTER awaiting page.close(),
but the page 'close' event handler can fire during that await and reassign
activeTabId — losing the race meant the last-tab auto-create never ran,
leaving the manager with zero tabs. Capture wasActive before closing, and
only reassign activeTabId when it no longer points at a live tab.

* fix(test): remove all 8 delayed process.exit teardown bombs — the tier-1 gate can finally fail

bun test runs every file in ONE process, so a 500ms setTimeout(process.exit(0))
armed in afterAll fired mid-way through a LATER file and killed the entire
suite with exit 0 and no summary — only ~16 of 434 files ran, and every
downstream failure was invisible (observed live throughout this wave's
enumeration). Changes, all guarded by fault injection:

- Replace every delayed-exit teardown with a time-boxed close of the file's
  own browser (8 files across browse/ and design/); stub the daemon
  /shutdown timer instead of letting its unconditional process.exit tear
  the runner down.
- test/no-suicide-exit.test.ts: static tripwire — no *.test.ts may schedule
  a delayed process.exit again.
- test/exit-propagation.test.ts + fixtures: fault injection with REAL bun
  output proves the truncation shape (exit 0, no summary) and that
  scripts/test-free-shards.ts now detects it: a shard exiting 0 WITHOUT
  bun's final summary line is treated as FAILED (exit code alone is not
  evidence of completion).
- handoff: the three headed-mode integration tests are darwin-skipped with
  a pointer to the known macOS headed-launch breakage (#2242/#2554); they
  keep running on Linux CI. Un-skip in the browse-daemon wave.
- feedback-roundtrip: repair the handler call sites unmasked by the fix —
  handlers take (command, args, session, bm); passing the manager where a
  session belongs broke all six tests.
- user-slug-fallback: HOME isolation makes endpoint_hash deterministic.

tmpFile() scratch files, and setup's smoke-test fixture/output all wrote

NUL-delimited SMARTPANTS_PRESERVED placeholder BEFORE the URL pass
runs, and URL_RE's \S+ swallowed the adjacent placeholder into the URL
match. The restore pass is single-shot, so the inner placeholder never
restored: raw "SMARTPANTS_PRESERVED_N" text leaked into the rendered
link, the </a> vanished, and link-blue styling bled into the rest of
the document (#2084). Excluding the NUL sentinel (\u0000) from the URL

Two paths put invisible content ahead of the first H1 and cost users a
blank page 1 (#1904):

  `break-before: page` and started on page 2. Non-rendering preambles
  now fold into the first real chapter (markup preserved, no page
  break); real text preambles keep their own chapter.

blank tab it starts from — and `browse newtab about:blank`, which
`make-pdf setup` runs as its Chromium smoke test, failed and surfaced

Allow about:blank ONLY, never the about: scheme: about:blank has no
origin, loads nothing and runs nothing, while about:config and friends
are real surfaces. Exact href match (lower-cased, since the URL parser
normalises the protocol but not the opaque part), so about:blankfoo

* fix(design): drop gpt-image-2 tool model that 400s under the gpt-4o orchestrator

The Responses API rejects pairing a gpt-4o orchestrator with an
image_generation tool spec'd as model: "gpt-image-2" (400
invalid_request_error), which took every design image call offline —
generate, variants, iterate (both threaded and fresh paths), evolve,
and /design-shotgun (#1771). gpt-image-2 is only valid under a gpt-5
orchestrator; with gpt-4o the tool must omit the model field (defaults
to gpt-image-1).

Remove the model field at all five call sites and add a static-grep
tripwire test (design/test/image-gen-pairing.test.ts) that fails CI if
any design/src module reintroduces the gpt-4o + gpt-image-2 pairing.
Re-enabling gpt-image-2 later requires bumping the orchestrator off
gpt-4o in the same diff, which the tripwire permits.

imported nothing, and the ingest still reported "written: N" from the STAGED

gbrain predates the flag, retry without it (subcommand --help is generic, so

* fix(session-update): un-wedge auto-upgrade — autostash over local patches, log the pull's real reason

On a normal install the tracked files ARE locally patched (skill-prefix
name rewrites, gbrain-refresh blocks), so the bare `git pull --ff-only`
refused on every run and auto-upgrade froze forever — observed as 308
consecutive PULL_FAILED entries with the reason discarded by 2>/dev/null.
Pull now runs --autostash (local patches ride over the update and pop back),
stderr is captured into the log so a genuine failure names its cause, an
autostash pop conflict recovers to a clean tree and re-renders the patches
(gstack-patch-names + gbrain-refresh, both idempotent), and a successful
pull re-renders them as a self-heal. Behavioral tests cover the wedge shape
and the reason logging.

Current Claude Code returns AskUserQuestion results as an OBJECT map keyed

legacy array shapes, so 86% of live records carried user_choice __unknown__
— and the bin then scored every one as followed_recommendation false,
silently poisoning plan-tune metrics. Adds the object-map extraction (exact
+ whitespace-normalized + single-question pairing, multiSelect joins,
annotations as free_text), strips the (Recommended) suffix from BOTH sides
of the comparison, skips the computation entirely on extraction failure,
and logs unrecognized shapes to hook-errors.log instead of embedding them

outermost STRONG marker wins (.git, package.json, pyproject.toml, Cargo.toml,
Gemfile, go.mod, .project.yaml), weak content markers (README, LICENSE) catch
non-code project folders, deploy artifacts are deliberately not markers, and
GSTACK_PROJECT_SLUG remains the escape hatch. The cache self-heals on

* fix(windows): grant icacls ACEs by *SID, not unqualified username

An unqualified username handed to icacls is ambiguous: on a machine whose
hostname equals the username (a common Windows setup), it resolves to the
MACHINE account instead of the user. Combined with /inheritance:r, that
leaves ~/.gstack with a single ACE matching nobody — the process that just
"secured" the directory locks itself out, and icacls still reports success.

Both icacls sites in the repo (restrictFilePermissions and
restrictDirectoryPermissions in browse/src/file-permissions.ts — the only
icacls call sites; setup has none) now grant via icacls' literal-SID form
`*<SID>`, resolved once per process from System32\whoami.exe (pinned to
System32 because a bare `whoami` under a bash-flavoured PATH picks up the
MSYS build, which rejects /user). Fallback when the SID can't be resolved
is the domain-qualified `USERDOMAIN\username` name, which is unambiguous
where the bare username was not.

Windows-only regression tests assert the hardened directory stays usable
by the calling process (readdir + write), which is exactly the check that
a not-toThrow assertion sailed past before.

* fix(windows): forward windowsHide through the bun-polyfill spawn shims

windowsHide is the one spawn option where Node's default is the opposite
of Bun's: Node shows the child's console window, Bun.spawn hides it.
The polyfill's spawn and spawnSync shims dropped the option entirely, so
the Node fallback path (dist/bun-polyfill.cjs) silently inverted the
behavior on the one platform the shim exists to serve — every watchdog
respawn of the terminal agent popped a visible bun.exe console window.

Three sites fixed:
- Bun.spawnSync shim: forwards windowsHide with Bun-matching default true
- Bun.spawn shim: same (stdio:'ignore' silences output but does NOT
  suppress the console window on Windows)
- spawnTerminalAgent in terminal-agent-control.ts: explicit
  windowsHide: true, so the Node fallback path behaves like Bun-native

An explicit windowsHide: false is honored at both shims. Three focused
tests pin the default-true, default-true-sync, and explicit-false paths
by intercepting child_process in a subprocess; the test file's require
path now uses forward slashes so it survives interpolation into a JS
string literal on Windows.

Supersedes PRs #2523, #2294 and #2290, which each covered a subset of
these sites.

* fix(watchdog): signal-0 liveness, tick-scaled respawn guard, windowsHide

Three-bug chain behind the Windows terminal-agent leak (console window
strobing every 60s, one orphaned agent per watchdog tick until the box
ran out of committable memory):

1. isProcessAlive shelled out to `tasklist /FI "PID eq <pid>"` on Windows
   with a 3s timeout. A Bun.spawnSync that hits its timeout still RETURNS
   with partial stdout, so the `.includes()` PID match read a LIVE agent
   as dead — killAgentByRecord skipped the kill, the watchdog respawned
   around the survivor, and every orphan slowed the next tasklist enough
   to produce the next false negative. Now: `process.kill(pid, 0)` on
   every platform (Node and Bun both map signal 0 to an OpenProcess
   existence check on Windows), with EPERM counted as alive. No
   subprocess, no timeout, no console window.

2. The respawn circuit-breaker was mathematically unreachable — verified
   in this tree: RESPAWN_GUARD_WINDOW_MS was a fixed 60_000 against a
   60_000ms default tick, and each tick pushes at most one respawn
   timestamp, so three pushes span ~120s and can never coexist inside a
   60s window (eviction is strict `>`, and setInterval drift plus
   per-tick work always ages the prior entry past the boundary). The
   guard could not fire at the default tick rate and a steady
   one-per-tick leak ran unbounded. The window now scales with the tick:
   max(60_000, tick * (RESPAWN_GUARD_MAX + 2)), so "3 crashes in quick
   succession → stop" holds at any tick value.

3. The tasklist probe popped a visible console per tick (no windowsHide).
   Removing the shell-out kills that site; the agent-spawn site itself
   already passes windowsHide: true (landed with the bun-polyfill
   windowsHide commit — PR #2414's terminal-agent-control.ts hunk is
   reconciled there rather than duplicated).

New browse/test/process-liveness-windows.test.ts pins all three: no
subprocess from the probe, a static tripwire against reintroducing
`tasklist` + `PID eq` liveness checks in src/, the spawnTerminalAgent
windowsHide + stdio contract, and the window-derived-from-tick
arithmetic. terminal-agent-watchdog.test.ts test 4 now pins the
window/tick relationship instead of the fixed literal that let this
ship. Also converts `new URL(import.meta.url).pathname` to
`import.meta.path` across the static-grep tests it touches — the
pathname form yields /C:/... on Windows and breaks path.resolve.

* fix(terminal-agent): tie agent lifetime to its owning browse server PID

The terminal agent is intentionally detached so it survives the
short-lived CLI launcher, but its real owner is the persistent browse
server. If that server crashed or was killed before running normal
shutdown, the agent was adopted by PID 1 and lived forever (#2019).

spawnTerminalAgent now requires an ownerPid and exports it to the agent
as BROWSE_OWNER_PID; all three spawn sites pass the server PID (cli.ts
cold-start, cli.ts supervisor respawn, server.ts watchdog). The agent
polls the owner with signal 0 every 15s (GSTACK_TERMINAL_OWNER_WATCHDOG_MS
to tune) on an unref'd timer and, when the owner disappears, exits
through the SAME cleanup path as an intentional SIGTERM shutdown — now
re-entrancy-guarded and also removing the terminal-internal-token file
alongside the port file and agent record.

Runtime test spawns a real agent tied to a throwaway owner process,
kills the owner, and asserts the agent exits and its discovery files
(terminal-agent-pid, terminal-port) are gone.

Reconciled with the watchdog commit's spawnTerminalAgent contract test
(process-liveness-windows.test.ts now passes ownerPid and pins the
BROWSE_OWNER_PID env forwarding).

Closes #2019.

* fix(windows): give the bun-polyfill spawn shim a real `exited` promise

Bun.spawn exposes `proc.exited` as a Promise resolving to the exit code.
The Node fallback shim (dist/bun-polyfill.cjs) returned no such field, so
every `await proc.exited` on the Windows path resolved instantly to
undefined — the Windows cookie picker (cookie-import-browser.ts races
proc.exited at three sites) read stdout before the child produced it and
silent-failed; browser-skill-commands and terminal-agent hit the same
class.

The shim now:
- drains stdout/stderr eagerly into capped in-memory buffers (Node's
  Readables are pull-based; without draining, a child writing past the
  OS pipe buffer blocks in write() and 'exit' never fires), replaying
  them as fresh single-shot Web ReadableStreams so reads work before or
  after awaiting exit;
- caps the buffer at 16 MB (GSTACK_SPAWN_MAX_BUFFER to override), still
  draining past the cap so a runaway child can't wedge or OOM;
- resolves `exited` with Bun-matching codes (exit code, 128+signal, 1 on
  spawn error) after both pipes finish, and resolves on 'error' too —
  Node fires 'error' without 'exit' when the binary is missing, which
  otherwise hangs the await forever.

Six tests pin exit codes, the read-after-exit ordering, spawn-failure
resolution, the buffer cap, and the large-output drain. Adapted to the
current test file (require path goes through the requirePath variable
from the windowsHide commit), and the 1 MB drain test's child now exits
in the write callback — on modern Node a pipe write past the OS buffer
is async and process.exit() straight after write() truncates at ~64 KB
even with a live reader, which fails the test for reasons unrelated to
the shim.

* fix(setup): BROWSE_BIN carries the .exe suffix on Windows

On Windows, `bun build --compile` emits browse.exe, but setup's
BROWSE_BIN pointed at the suffixless path — so the post-build gate
(`[ ! -x "$BROWSE_BIN" ]` → "browse binary missing") could never pass on
Windows even after a fully successful build, while the build step itself
reported success. Closes #2291.

Applied the PR's override after the IS_WINDOWS detection, and also to
the second BROWSE_BIN assignment the PR predates: the direct-Codex-
install migration path re-derives BROWSE_BIN from the migrated dir and
would otherwise drop the suffix again on Windows.

* fix(setup): link lib/ beside bin/ at all five host-install sites

bin/ scripts import shared modules via ../lib (gstack-learnings-log →
lib/jsonl-store.ts is the reported case), so any runtime root that
exposes bin/ without lib/ breaks 13 bin/ commands — learnings-log,
decision-log, telemetry and friends fail with "Cannot find module
.../lib/jsonl-store.ts" on every non-Claude install, silently from the
skills' perspective.

All five host-install sites now carry lib/ next to bin/, each through
the existing _link_or_copy helper (never raw ln — the static invariant
in test/setup-windows-fallback.test.ts enforces this):

- .agents sidecar (create_agents_sidecar asset loop)
- Codex runtime root (create_codex_runtime_root)
- Factory runtime root (create_factory_runtime_root)
- OpenCode runtime root (create_opencode_runtime_root)
- Kiro install block

New test/setup-runtime-lib-command.test.ts executes the real setup shell
for each root in a sandbox (both the symlink branch and the Windows copy

* fix(setup): ship supabase/config.sh with every host runtime root

Distinct from the lib/-beside-bin/ defect: gstack-telemetry-sync,
gstack-update-check, gstack-security-dashboard and
gstack-community-dashboard all source $GSTACK_DIR/supabase/config.sh to
resolve GSTACK_SUPABASE_URL, where GSTACK_DIR is the installed root
(parent of bin/). The [ -f ... ] guard means a root without the file
degrades SILENTLY — telemetry and update checks just stop resolving the
project URL on non-Claude installs. Closes #2215.

setup now links supabase/config.sh (file-level on purpose — migrations/
and functions/ are dev-only) via _link_or_copy at all five host-install
sites: the PR's four (Codex, Factory, OpenCode runtime roots + the Kiro
block) plus the .agents sidecar, whose bin/ resolves the same relative
path and which the PR predates covering.

The runtime-root test now asserts supabase/config.sh is present in
every built root, on both the symlink and Windows-copy branches.

* ci(windows): curate the fix-wave regression tests into the windows-latest run

The windows-free-tests curated set is derived (POSIX-fragility regex scan
+ explicit deny list), and two of this wave's Windows regression files
were auto-excluded on false-positive pattern hits:

- browse/test/file-permissions.test.ts tripped the POSIX-mode-bitmask
  pattern, but every `mode & 0o777` assertion is platform-guarded — and
  the file carries the win32-only icacls-by-SID regression tests, which
  can only ever execute on windows-latest.
- browse/test/terminal-agent-owner-watchdog.test.ts tripped the
  spawn(['bun','run',...]) pattern whose reason is the Playwright-bound
  browse server; it actually spawns terminal-agent.ts (fs/path/crypto +
  local helpers only, no Playwright at module scope), and the owner-PID
  orphan leak it pins was reported on Windows (#2019).

Adds a KNOWN_WINDOWS_SAFE force-include list (mirror of
KNOWN_WINDOWS_INCOMPATIBLE, each entry carrying its false-positive
rationale) consulted before the pattern scan, and makes the
owner-watchdog test's throwaway owner process Windows-portable
(process.execPath instead of `sleep`, which a bare runner may not have).

The wave's other new files need no wiring: process-liveness-windows and
the bun-polyfill windowsHide/exited tests pass curation automatically;
setup-runtime-lib-command self-skips on win32 by design (its Windows
branch is exercised by simulating IS_WINDOWS=1 under bash), so
force-including it would add a permanently-skipped file.

* fix(mktemp): move the X-run to the end of every temp-file template (BSD/busybox safe)

BSD mktemp (macOS) does not substitute an X-run that has a suffix after it:
`mktemp "$TMP_ROOT/codex-err-XXXXXX.txt"` creates a LITERAL
codex-err-XXXXXX.txt on the first call (exit 0) and every later call fails
with `mkstemp failed: File exists` — so /codex breaks from the SECOND run on
every Mac, masquerading as a model stall. busybox mktemp (Alpine) rejects the
template on the first run. Fixes #2091, #2370.

Union of both community fixes, compared at the diff level:
- PR #2372: all 11 source sites with a suffix after the X-run — codex
  SKILL.md.tmpl (5), claude SKILL.md.tmpl (3), bin/gstack-developer-profile
  (2, suffix folded into the prefix: .json.tmp.XXXXXX), and the office-hours
  codex pass in scripts/resolvers/review.ts (1).
- PR #2103: the second half of #2091 — bin/gstack-paths now strips the
  trailing slash from TMP_ROOT at the source (macOS $TMPDIR ends in `/`),
  plus runtime tests pinning that normalization.

New repo-wide tripwire in test/regression-issue2091-bsd-mktemp.test.ts:
every .tmpl, every SKILL.md, and every scripts/resolvers/*.ts is swept —
no mktemp template may carry a suffix after the X-run, with a self-test so
the detector can't be quietly blinded. Generated SKILL.md files regenerated

* fix(codex,review,ship): scope codex review with an explicit --base flag, never prompt text

`codex review` takes its scope ONLY from --base/--commit/--uncommitted. The
positional [PROMPT] is mutually exclusive with all three, and a prompt-only
`codex review "<text>"` silently falls back to the uncommitted working-tree
scope (verified on 0.144.1: it runs `git status --short; git diff` and
reviews that) — so the previous prompt-based scoping produced a
confidently-worded review of the WRONG changes and read "no changes" on a
clean tree. Every diff pass now invokes `codex review --base <base>` with no
prompt argument: /codex Step 2A default path, the /review structured pass,
and the /ship adversarial-section pass (all via scripts/resolvers/review.ts).

Custom review instructions keep their own `codex exec` path (the CLI rejects
prompt + scope flag together), with the filesystem boundary preserved there.
Two new Error Handling entries teach the failure shapes: the argv-parse
error, and the "review says no changes on a branch full of changes" symptom.

Tests updated to pin the new invariant instead of banning the fix: the old
assertions required the diff range in prompt text and banned the
`--base <base> -c '...'` substring, which the correct scoped form contains.
Also deletes test/fixtures/golden-ship-claude.md — a 2,565-line orphaned
fixture referenced by zero tests (the live goldens are in
test/fixtures/golden/, compared by test/host-config.test.ts); the factory
golden is refreshed from the regenerated output. Generated SKILL.md files

* fix(review,ship): run the codex diff passes under the timeout wrapper (#1036)

The `_gstack_codex_timeout_wrapper` added in #1056 was wired into
codex/SKILL.md but never into the /review and /ship diff passes, which kept
running under a bare 5-minute Bash gate. An unwrapped stall returns no exit
code and no output, which downstream reads as "Codex reviewed and found
nothing" — a truncated pass silently became a clean bill. Measured on
codex-cli 0.145.0: a pass was killed at 287s of a 300s budget mid-tool-call,
and the same prompt completed in 336s.

Both passes in scripts/resolvers/review.ts (adversarial `codex exec` and the
structured `codex review --base` pass) now re-source gstack-codex-probe and
run under `_gstack_codex_timeout_wrapper 540`, with the Bash tool gate raised
to 600000 ms so the wrapper fires FIRST and a stall surfaces as a diagnosable
exit 124. The timeout guidance now says a timed-out pass is MISSING COVERAGE,
not a clean result, and points at the run's rollout log under
~/.codex/sessions/ for partial output. The stale "timeout doesn't exist on
macOS" claim is gone — the wrapper resolves gtimeout, then timeout, then runs
unwrapped, so it is safe without coreutils.

Static guards in test/codex-hardening.test.ts pin all three sites (resolver,
review/SKILL.md, ship/sections/adversarial.md): both calls wrapped, wrapper
budget strictly under the Bash gate, and no reappearance of the macOS claim
that steered these call sites away from the wrapper in the first place. The
Claude-output path guard in test/gen-skill-docs.test.ts now scrubs
~/.codex/sessions/ (a user-facing Codex CLI path, same class as the
~/.codex/logs/ exemption) before banning Codex host paths. Generated files
regenerated via gen:skill-docs; factory golden refreshed.

* fix(codex): sandbox the review path, fail the gate closed, order timeouts wrapper-first

Closes #2496, #2524, #2477 — three defects in the class "a guard that
reports success while doing nothing", all in codex/SKILL.md.tmpl:

(a) Review sandbox. The default `codex review` path was the only codex call
with no sandbox override, inheriting ~/.codex/config.toml's default — write
access on a trusted project — while Important Rules claimed read-only.
Top-level `codex review` has no -s/--sandbox flag (verified on 0.147.0), so
the invocation now pins `-c 'sandbox_mode="read-only"'`, the same form the
consult-resume path already uses.

(b) Fail-closed verdict gate. The old rule ("no [P1] found → PASS") could
not fail on the default path: native `codex review` output carries no
bracketed tags, and a non-zero exit, expired auth, timeout, or empty result
also contains no [P1] — all read as PASS. The gate is now an ordered,
fail-closed check: non-zero exit → FAIL; empty output → FAIL; [P0]/[P1]
(bracketed or codex's native labels) → FAIL with count; NO severity tags at
all → FAIL requiring a human read; PASS is only reachable through the
explicit tagged-advisory-only branch. [P0] is recognized as blocking, and
the review-log findings count includes it.

(c) Bash gate above the wrapper. Step 2A instructed `timeout: 300000` under
a 330s wrapper, and Challenge's 300s gate sat under a 600s wrapper — the
harness killed the call before the wrapper could emit its diagnosable
exit-124 message. Every Bash gate now sits strictly ABOVE its wrapper:
360000 over the 330s review wrapper, 660000 over the 600s challenge/consult
wrappers, with the ordering rationale stated at each site.

Also from #2477/#2524: a new Error Handling entry for the model-entitlement
400 ("The '<model>' model is not supported...") pointing at the `model =`
pin and `[notice.model_migrations]` in ~/.codex/config.toml and saying
exactly which override to retry with (-m for exec-based modes,
`-c model="..."` for review mode, which rejects -m); the Model & Reasoning
section no longer documents `-m` for `/codex review`.

Static assertions in test/codex-hardening.test.ts pin (a)-(c) across both
the .tmpl and the generated SKILL.md: every scoped review invocation carries
sandbox_mode="read-only" and never -s; the default-PASS sentence is banned
and the fail-closed branches are present; and per-section, every Bash
`timeout: N` is strictly greater than every wrapper budget, with 2A/2B/2C
all required to be inspected. Generated SKILL.md regenerated via
gen:skill-docs in this commit.

- Delete sidebar-security.test.ts + security-source-contracts.test.ts: crashed
  at module load (unguarded readFileSync of the deleted file); per-assertion
  triage confirmed every SERVER_SRC pin targeted the deleted chat prompt
  builder (zero hits in today's server.ts) — nothing to port.
- Delete sidebar-integration.test.ts: 11 of 13 tests exercised deleted
  endpoints (/sidebar-command queue, /sidebar-agent/event, chat buffer); the 2
  passing tests pinned only the blanket auth gate, covered by
  server-auth.test.ts + dual-listener.test.ts.
- Delete test/skill-e2e-sidebar.test.ts: E2E for the deleted queue flow.
- sidebar-ux.test.ts 1,669 -> 830 lines: 20 dead-chat describes + 15 dead
  tests removed (incl. 10 vacuous passes asserting on empty indexOf slices);
  2 stale pins on LIVE features fixed (content.js typed-catch CSSOM fallback,
  arrow-hint window widened). 95 pass / 0 fail.
- sidebar-tabs.test.ts: both failures were stale pins, not regressions —
  forceRestart's deliberate ws.close(4001) and the terminal-agent spawn that
  moved into spawnTerminalAgent() (identity-based kill refactor). 28 pass.
- touchfiles.ts: drop the three sidebar E2E entries from BOTH maps
  (E2E_TOUCHFILES + E2E_TIERS) — they pointed diff-selection at the deleted
  file, so those tests were unreachable by any diff.
- test-free-shards.ts: remove the now-dead sidebar-agent exclusion pattern.

* feat(ci): run the free test suite in CI (it ran nowhere)

The full free suite (bun test: browse/test/ + test/ + make-pdf/test/) had no CI
job on any Linux/macOS runner — only Windows curated shards, paid evals, and
doc-freshness gates existed. That's how two module-load-crashing test files
survived 48 versions.

Same cached Dockerfile.ci image and container wiring as evals.yml (deps
restore, build, Chromium verify). Includes a module-load-error guard: older
Bun reported test-file import crashes with exit 0 on macOS/Linux, so the job
also fails on any nonzero 'N errors' count in the summary — future crash-class
regressions can't hide from the exact job built to catch them.

* feat(test): validate touchfile dependency paths exist on disk

New guard in touchfiles.test.ts: every non-glob dep path must exist, and every
glob's anchor directory must exist. This is the axis the 181-key two-map sync
discipline never covered — an entry can point at a long-deleted file and
diff-based selection then silently never triggers those tests (the sidebar
trio sat rotted for 48 versions).

First run immediately caught a fourth rotted entry: 'spec authored quality'
referenced test/fixtures/spec/** (directory does not exist) and selected for a
judge test that exists nowhere in the repo. Removed.

* fix(security): remove deleted /sidebar-chat endpoint from tunnel allowlist

TUNNEL_PATHS is the audited tunnel attack surface — its own comment says every
addition widens it. '/sidebar-chat' stayed in the set after the endpoint was
deleted with the chat-queue path, meaning any future route matching that path
would have been silently tunnel-exposed. The set is now exactly the pair
ceremony (/connect) and the scoped command endpoint (/command), and the
dual-listener closed-set pin enforces that.

Also repairs a pre-existing red pin in dual-listener.test.ts: v1.63.0.0 made
the tunnel allowlist args-aware (canDispatchOverTunnel gained a second param)
without updating the test — red on main since then, invisible because the free
suite had no CI job.

* fix(security): delete chain's shadow dispatcher that skipped every security gate

meta-commands.ts carried a 'CLI mode' fallback that re-implemented command
routing without the server pipeline's gates: no scope check, no domain check,
no tab ownership, no rate limit, no hidden-element stripping, no scoped-token
enveloping — and it called handleReadCommand without a BrowserManager, which
also skipped the JS-origin cookie-exfiltration assertion. It was unreachable
in production (server.ts always passes executeCommand) and one boolean away
from being live.

chain now hard-errors without a server context. handleReadCommand's bm param
is required and assertJsOriginAllowed runs unconditionally. The chain tests
that exercised the deleted fallback now route through a server-shaped
executeCommand adapter (real handlers + trust wrapping + {status,result}
envelope), so their behavioral coverage — sequencing, trust markers, pipe
format, aliases, error reporting — survives on the production-shaped path.

* fix(extension): delete the dead chat-queue client surface

The sidebar-command handler in background.js POSTed to a server endpoint that
no longer exists (deleted with the chat queue) — ~35 lines of fully-wired dead
code including error handling for the permanent 404, plus its allowlist entry.
No sender in the extension ever emitted the message type.

chatEnabled leaves the /health contract (server hardcoded false, background.js
re-derived it, nothing consumed it — the chat input element it guarded is gone
from sidepanel.html). BROWSE_SIDEBAR_CHAT env flag had zero readers.

* fix(security): delete dead exports the ripped chat path left behind

Three-way split by importer class:

(a) Zero importers, deleted: the whole attack-attempt logging cluster in
security.ts (logAttempt, AttemptRecord, salted hashPayload + device-salt,
attempts.jsonl rotation, telemetry spawn plumbing incl.
buildTelemetrySpawnCommand/resolveBashBinary — the LIVE attempts.jsonl writer
is tunnel-denial-log.ts with its own rotation); the decision-file handshake
(writeDecision/readDecision/clearDecision/excerptForReview — written for
sidebar-agent's poll loop, which no longer exists); sidebar-utils.ts (whole
module — its sanitizeExtensionUrl 'sanitized before embedding in a prompt'
for the deleted prompt builder); 8 dead server.ts imports (sanitizeExtensionUrl,
generateCanary, injectCanary, writeDecision, rotateRoot, serializeRegistry,
restoreRegistry, clearAgentRecord); buildPtyClearCookie + buildSseClearCookie;
WEBDRIVER_MASK_SCRIPT (orphaned by the D7 stealth narrowing — applyStealth
never used it).

(b) Dead-pin tests edited with their exports: the 'still exported' pin in
stealth-layer-c, the string-content describe in stealth-webdriver (its live
applyStealth behavioral coverage untouched), the clear-cookie assertions,
security-review-flow.test.ts deleted whole (all 4 describes exercised the
dead decision mechanism, incl. a 'simulated sidebar-agent poll loop').

(c) KEPT deliberately: leaseCount (live behavioral coverage),
extractPtyCookie + validatePtySessionToken (extractPtyCookie is adopted by
the terminal-agent cookie-parse unification later in this wave),
resetSessionMarker + clearContentFilters (test-support API for the live
content-security layer).

Also fixes two pre-existing red pins found while here, invisible until the
free suite got a CI job: the v1.44 spawnClaude->maybeSpawnPty rename in
terminal-agent.test.ts, and a cross-file test-isolation bug where
content-security.test.ts's clearContentFilters() wiped the auto-registered
url-blocklist filter for every later file in the same bun process
(security-integration.test.ts failed on co-run; afterAll now restores it).

* fix(security): delete the dead ML layers — transcript classifier and DeBERTa ensemble

The L4b Haiku transcript classifier and the opt-in DeBERTa ensemble
(GSTACK_SECURITY_ENSEMBLE=deberta, a documented 721MB download) had ZERO
production callers since the chat-path agent that invoked them was ripped.
The only live ML path is scanPageContent (testsavant) inside the security
sidecar subprocess. Deleted by import graph:

- security-classifier.ts 614 -> 265 lines: HAIKU_MODEL, checkTranscript,
  shouldRunTranscriptCheck, loadDeberta, scanPageContentDeberta, ToolCallInput,
  all DEBERTA_* consts + load state. Header now states the live truth
  (imported only by security-sidecar-entry.ts). downloadFile kept, name
  intact — it is an enumerated egress sink (HF model download).
- security-bunnative.ts + test: a research skeleton self-described as 'NOT a
  production replacement', shipped into src/ with zero importers.
- security-bench-ensemble{,-live}.test.ts + the Haiku response fixture: a
  paid live-model benchmark for a layer that could not fire. The
  security-classifier-tdz test's only case exercised checkTranscript — gone.
- security.ts: layer-model header rewritten to the live architecture;
  StatusDetail.layers -> {testsavant, canary}; getStatus() no longer requires
  the impossible transcript==='ok' for 'protected' (old on-disk session state
  with a transcript key is tolerated on read, never re-emitted).
- security-sidecar-entry.ts needed zero changes: it serializes
  getClassifierStatus() verbatim and no consumer read .transcript (verified
  in sidecar-client + server.ts).
- BROWSER.md security section matches reality (ensemble knob gone, 112MB not
  22MB, sidecar hosting documented). combineVerdict/THRESHOLDS retained as
  the pure, tested combiner of record — comments now flag transcript/deberta
  votes as producer-less.

Net: 26 pass in security.test.ts incl. a NEW regression test for stale-
transcript disk tolerance; egress-receipt tripwire green.

* docs: scrub the sidebar-agent ghost from comments and CLAUDE.md

20+ comments across 10 files still described the deleted sidebar-agent.ts as a
live process — including load-bearing architecture claims ('IMPORTED ONLY BY
sidebar-agent.ts', 'sidebar-agent fills this in on first prompt-injection
load', 'kill sidebar-agent' in shutdown docs) and ~60 lines of tombstone
blocks in server.ts enumerating deleted identifiers by name (a false grep
surface: searching processAgentEvent hit server.ts and looked live).

CLAUDE.md's security-stack section now documents the LIVE architecture: L1-L3
content filters + testsavant via the security sidecar subprocess; the
L4b/ensemble rows, the GSTACK_SECURITY_ENSEMBLE knob, and the 721MB DeBERTa
download are gone (deleted as dead code this wave) with an explicit
do-not-re-document note; attempts.jsonl is correctly attributed to
tunnel-denial-log.ts; the no-live-writer status of classifierStatus is stated.

Comments that survive now describe what IS, not what WAS: the promotion gate
in domain-skills.ts explains why classifier_score>0 is load-bearing given no
L4 load-time scan exists; file-permissions.ts names real sensitive files.

* fix(gen): delete the codex-helpers shadow module

gen-skill-docs.ts imported externalSkillName (unaliased) from
resolvers/codex-helpers.ts at line 21 and then re-declared the same function
locally — the import was silently shadowed, and the imported copy was the
STALE one (it lacked the frontmatterName param the local copy grew). Three
more functions were byte-identical duplicates, imported only under _-prefixed
aliases to keep the module 'referenced', and transformFrontmatter was a
superseded hardcoded-Codex variant. Nothing else imported the module.

Also drops three dead top-of-file imports (COMMAND_DESCRIPTIONS,
SNAPSHOT_FLAGS — which pulled the whole browse/src module graph into every
generator run for nothing — and an unused review-resolver trio).

Proof: bun run gen:skill-docs exits 0 with a byte-identical tree (zero-diff
regen); gen-skill-docs.test.ts 405/405 green.

* fix(server): delete ServerConfig.idleTimeoutMs + chromiumProfile — documented, never read

Both fields carried JSDoc asserting embedder behavior that did not exist:
the idle check reads the module-level IDLE_TIMEOUT_MS env constant, and both
resolveChromiumProfile() call sites pass no argument. Worse than absent — an
embedder passing idleTimeoutMs: 5000 silently got 30 minutes.

Wiring them honestly is impossible today: the idle timer, activity state, and
shutdown target are module-global, so a per-factory value would lie for any
process running more than one handler. Deleted instead, with a ServerConfig
note pointing at the deferred singleton/route-table refactor where real
support belongs. BROWSE_IDLE_TIMEOUT and CHROMIUM_PROFILE env remain the
honest knobs.

* fix(security): wire appendSecureFile at the four real log-append sites

file-permissions.ts carries a 24-line rationale for why POSIX mode bits are
insufficient on Windows and implements appendSecureFile (0600 at create,
Windows ACL on first write only) — but its single caller was the dead
logAttempt, while the four REAL page-content log writers (console/network/
dialog logs in server.ts, the command audit log) used raw fs.appendFileSync
with no mode. Page-content-derived logs now get owner-only permissions from
birth on every platform.

Verified before wiring: mode applies atomically at create via appendFileSync
{mode}, and the ACL pass runs only on first write — no per-append subprocess
cost on the hot console-log path.

* fix(stealth): handoff() uses the shared profile resolution + lock cleanup

The headless-to-headed handoff path hardcoded ~/.gstack/chromium-profile,
silently ignoring $CHROMIUM_PROFILE and $GSTACK_HOME (gbrowser's gbd sets
per-workspace profiles), and skipped cleanSingletonLocks() — so a handoff
into a profile with a stale SingletonLock could hang where launchHeaded()
would have recovered.

This was the third live drift between the three Chromium launch paths; the
first two are documented in comments as shipped stealth regressions. Minimal
targeted fix — the full buildLaunchConfig() extraction stays in the deferred
queue.

* fix(gen): resolver registry describes the template language again

Seven registered {{PLACEHOLDER}}s had zero uses in any .tmpl (checked in both
bare and :arg forms): REDACT_TAXONOMY_TABLE, TEST_COVERAGE_AUDIT_REVIEW,
MODEL_OVERLAY, QUESTION_PREFERENCE_CHECK, QUESTION_LOG, INLINE_TUNE_FEEDBACK,
MAKE_PDF_SETUP. The last two of those families are invoked programmatically by
preamble.ts (functions kept, registry entries dropped); the question-tuning
trio and the review coverage-audit wrapper were documented by their own module
as existing 'for unit testing' that no test performed — deleted, along with
generateRedactTaxonomyTable + its EXAMPLE/TIER_BLURB constants (its '/cso
renders the full table' comment was itself stale) and its test describe.

Also deletes the gated-resolver mechanism (ResolverEntry/appliesTo/
unwrapResolver + test/resolver-entry.test.ts): fully built, fully tested,
used by zero of the 65 registry entries — the generator loop simplifies to a
direct function call. CLAUDE.md's redact-doc line stops advertising the dead
token.

Proof: zero-diff regen (0 SKILL.md changed); gen-skill-docs + skill-validation
737 tests green.

* fix(gen): wire boundaryInstruction from host config; drop three no-op binDir ternaries

hosts/codex.ts declared boundaryInstruction and nothing read it — review.ts
kept its own byte-identical CODEX_BOUNDARY literal (verified equal + trailing
escaped newlines). The resolver now reads the config, so the boundary has one
owner. (autoplan's template carries deliberately generic variants, enforced by
gen-skill-docs.test.ts:1358 — untouched by design.)

The 'ctx.host === codex ? $GSTACK_BIN : ctx.paths.binDir' ternary appeared in
three resolvers and could never change the result: resolvers/types.ts already
sets binDir to $GSTACK_BIN for every usesEnvVars host including codex.

Proof: zero-diff regen for claude AND codex hosts; gen-skill-docs +
host-config suites green.

* fix(test-infra): judge uses resolveClaudeBinary; eval:watch reads the real partials dir

judgePtyState spawned the bare string 'claude' three definitions below the
resolveClaudeBinary() helper this same file exports — broken under hermetic
PATHs where every other launch in the file resolves correctly.

eval:watch read _partial-e2e.json from the legacy global ~/.gstack-dev/evals/
while EvalCollector writes it into the per-project eval dir (or
GSTACK_EVAL_DIR) — so the dashboard's completed-tests panel was empty
whenever slug detection succeeded, i.e. the normal case. The heartbeat and
per-run progress logs stay global by design (session-runner.ts: 'heartbeat
stays global'). The three eval-CLI docstrings stop claiming the legacy dir
is the primary location.

* fix(test): delete the superseded SDK ship-idempotency suite and three orphaned fixtures

test/skill-e2e-ship-idempotency.test.ts's own header documented that the
monolith's SDK-harness version tests a synthetic prompt while it exercises
the real /ship skill — the author knew the old suite was superseded and left
both running, two paid LLM runs for one behavior. The weaker copy is gone;
its 'ship-idempotency' diff-selection key goes with it (the dedicated file is
periodic-tier, which always runs under EVALS_ALL — the key had no remaining
consumer).

Fixture rot: test/fixtures/golden-ship-claude.md was a 128KB zero-reader
orphan that had drifted 46KB from its live successor
(test/fixtures/golden/claude-ship-SKILL.md) while looking authoritative;
parity-baseline-v1.46.0.0.json and v1.53.0.0.json had zero readers (three
tests pin three OTHER baseline versions — consolidation is queued, deletion
of the unreferenced two is free).

* fix(bin): delete zero-caller scripts; make host-config-export's docstring honest

- bin/gstack-open-url (14 lines): announced in a CHANGELOG entry, wired into
  nothing, ever. bin/gstack-platform-detect (27 lines): zero callers, and its
  hand-rolled host list was already stale (SLATE_HOST.md cites it as a
  problem). Note: the deprecated gstack-brain-consumer/reader pair the audit
  flagged was already deleted upstream in v1.63 with a stay-deleted tripwire.
- scripts/task-emission-schema.ts (61 lines): a typed schema module nothing
  imported; the tasks-section comment now documents the JSONL fields inline.
- scripts/host-config-export.ts claimed to be the 'shell bridge for the bash
  setup script' — setup never calls it (its hand-rolled host lists drifting
  is a known follow-up). Docstring now states what it IS: a standalone,
  test-pinned query CLI not yet wired into setup. Its validateValue +
  CLI_REGEX/PATH_REGEX internals were dead (defined for a guarantee the
  header claimed but nothing enforced).
- KEPT deliberately: scripts/preflight-agent-sdk.ts — a documented manual
  diagnostic (CONTRIBUTING.md + USING_GBRAIN_WITH_GSTACK.md reference it).

* fix(server): one lone-surrogate sanitizer, one sanitizeReplacer, one startTunnel

Three copies of the surrogate sanitizer existed with two algorithms
(sanitize.ts regex vs a hand-rolled charCodeAt walk in server.ts — verified
byte-identical across 11 edge cases before converging) plus two identical
sanitizeReplacer definitions each wrapping a different copy. sanitize.ts is
now the single source of truth; the runs-INSIDE-JSON.stringify egress
invariant is unchanged at every call site and its pin tests were adapted to
the new import shape without losing intent.

The ngrok tunnel-start sequence existed three times in server.ts — the
/tunnel/start route and the BROWSE_TUNNEL=1 autostart were line-for-line
equivalent (a comment admitted 'Same cleanup as /tunnel/start's error path').
One startTunnel() now owns the ephemeral loopback bind, the pre-send egress
receipt, the state-file RMW via tmpStatePath(), and the ordered error-path
cleanup; callers keep their distinct response surfaces. The
BROWSE_TUNNEL_LOCAL_ONLY test path shares nothing (no ngrok, different state
field) and deliberately stays separate.

* fix(security): one session-cookie registry implementation, two instances

pty-session-cookie.ts and sse-session-cookie.ts were byte-identical modulo
the cookie name — mint/validate/parse/prune/TTL, the exact code a security
fix would have to land in twice (and a third hand-rolled cookie parse in
terminal-agent.ts had already diverged; unified next commit).
createSessionCookieStore() owns the implementation; both modules become thin
instantiations keeping every exported name, their distinct threat-model
docstrings, and separate token spaces (an SSE-read cookie must never grant
PTY access). pty-session-lease.ts deliberately stays out — different contract
(sessionId/secret split, refresh, env TTL).

The factory imports nothing from token-registry (cookie-picker-auth-isolation
invariant, still pinned by sse-session-cookie.test.ts).

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

* fix(security): terminal-agent uses the shared PTY cookie parser

The /ws upgrade's cookie fallback hand-parsed the Cookie header inline — the
fourth copy of the session-cookie parse, and the one that had already
diverged from the others. Parsing now goes through extractPtyCookie;
validation deliberately stays against the agent's own in-process validTokens
map (the server's registry lives in a different process). The ws-handler pin
test now pins the shared-parser call instead of the raw cookie-name literal.

* refactor(hosts): defineHost() factory — 10 copy-paste host files become declarations

hosts/*.ts were ten copies of one file: runtimeRoot byte-identical in 9/10,
pathRewrites mechanically derivable from the host name for 7/10, the 11-entry
toolRewrites map byte-identical between openclaw and gbrain, and every asset
change a 10-file edit (cursor and slate had already fallen out of three other
hand-maintained lists). defineHost() owns the defaults; each host file now
declares only what makes it different (slate/cursor: 8 lines each). Shared
constants: CROSS_MODEL_RESOLVERS, GBRAIN_RESOLVERS, EXEC_STYLE_TOOL_REWRITES.
Genuinely-different things stayed explicit: codex/factory $GSTACK_ROOT
rewrites, hermes's tool vocabulary, claude's denylist+prefixable install,
opencode's wider runtimeRoot.

Proof: JSON.stringify(ALL_HOST_CONFIGS) dump-diff before/after EMPTY (and a
runtime walk confirmed no function-valued or undefined-keyed fields, so the
JSON diff is complete); gen:skill-docs --host all zero-diff; host-config +
gen-skill-docs + idempotency suites 485/485. Host files 595 -> 285 lines.
docs/ADDING_A_HOST.md teaches the factory pattern.

* feat(lib): fs-atomic — one atomic-write implementation, with the race actually fixed

Atomic tmp-write-then-rename was reimplemented ~20 times across lib/, bin/,
and browse/src with three tmp-suffix conventions. One of them was a latent
bug this commit closes: lib/worktree.ts used a bare '.tmp' suffix — the
deterministic-tmp collision race browse/src/server.ts documents having hit
in production (its fix, pid+random, was trapped in a comment at one site).

lib/fs-atomic.ts: atomicWriteSync (always throws, best-effort tmp cleanup,
pid+random suffix, optional mode applied at tmp creation so the file never
exists with looser permissions) + atomicWriteQuiet (shutdown paths only).
Unit tests pin the throw/quiet contracts, 0600 mode, tmp-name uniqueness
(captured via the read-only-dir failure path — Bun's fs exports are
readonly, no monkeypatching), and no-stray-tmp cleanup.

Migrated: lib/worktree.ts (the bare-.tmp bug), lib/gstack-decision.ts
(snapshot + compact log), lib/gbrain-local-status.ts (probe cache). browse
sites follow separately.

* fix(lib): jsonl-store's docstring stops lying; mode option added; lib bypasses adopted

The header claimed 'single source of truth... the ONLY copy' with write-time
injection REJECTION — while appendJsonl never screened anything, only 1 of
~10 JSONL stores imported it, and a bypass appender lived in the same
directory. Now: the contract is explicit (screening is the CALLER's job via
hasInjection/firstInjectionMatch; the enforcing callers are named), a
option applies 0600 at create for sensitive stores, and the lib bypasses are
adopted (gstack-memory-helpers ×2, redact-audit-log — which keeps its chmod
backstop for files created looser by pre-mode versions). browse/src keeps
its own appenders by design (compiled-binary surface, own secure-append
helper) and the header now says so. gstack-decision's batched archive append
stays deliberate (single-write crash-window semantics appendJsonl's
one-record contract can't express).

New pins: 0600-at-create, and a test that documents appendJsonl does NOT
self-screen — so nobody can re-document it as self-screening without making
it true.

* fix(browse): migrate hand-rolled atomic writes to lib/fs-atomic

Seven sites, each audited for its existing throw-vs-swallow contract before
migrating: writeSessionState + the four fire-and-forget tab/state writers use
atomicWriteQuiet (they swallowed before); writeAgentRecord + the boot-time
port-file write use atomicWriteSync (they threw before — and writeAgentRecord
previously leaked its tmp file on rename failure, which the helper cleans).
All carry {mode: 0o600} plus restrictFilePermissions after successful writes,
preserving the Windows ACL hardening that writeSecureFile provided (mode bits
are POSIX-only). server.ts untouched: its three state writes route through
tmpStatePath(), pinned by server-tmp-state-path.test.ts.

* fix(hosts): delete five dead HostConfig fields

metadataFormat (generator hardcodes openai.yaml), sidecar (behavior lives in
setup's create_agents_sidecar — knowledge preserved as a comment in codex.ts),
install.prefixable (skill_prefix is implemented entirely in bin/gstack-config),
staticFiles (docstring cited a SOUL.md that never existed anywhere), and
adapter (its only would-be consumer, openclaw-adapter.ts, was fully dead —
with a test asserting the field was undefined). Kept: learningsMode (wired
next), linkingStrategy (validation reads it), coAuthorTrailer (consumed by
resolvers/utility.ts).

Proof: JSON dump diff shows ONLY the deleted keys vanishing; zero-diff regen
across all 10 hosts; host-config + gen-skill-docs suites green. Note: this
commit also carries chunk-23 edits to the shared hosts/claude.ts +
define-host.ts + host-config.test.ts files (skipSkills collapse, stale
line-number comment drops) — pathspec commits, concurrent prep.

* fix(gen): preamble tiers are explicit; silent ?? 4 default becomes an error; spec stops rendering its preamble twice

Eight skills (scrape, diagram, spec, skillify, pair-agent, landing-report,
open-gstack-browser + its connect-chrome symlink) silently received the
HEAVIEST tier-4 preamble because a missing frontmatter field defaulted to 4.
Tiers are now declared in every {{PREAMBLE}} template's frontmatter and a
missing declaration throws at generation time with the template path (the 5
templates without {{PREAMBLE}} never invoke the resolver). The stale
hand-written tier-map comment (wrong in 3 of 4 rows) is gone.

Bonus bug fixed: spec/SKILL.md.tmpl mentioned {{PREAMBLE}} in prose, so the
generator inlined the ENTIRE preamble a second time — spec/SKILL.md shrinks
127,462 -> 80,924 bytes (-46,538) from de-duplication alone. skill-size-budget
gains a reasoned INTENTIONAL_SHRINKS entry (its frozen baseline had measured
the doubled-preamble bug). New tests: missing-tier throw carries the path;
every {{PREAMBLE}} template declares a tier. (Carries chunk-23 edits in the
shared test/gen-skill-docs.test.ts.)

* fix(gen): learningsMode is read from host config, not a hardcoded host name

resolvers/learnings.ts branched on ctx.host === 'codex' while every host
declared learningsMode — the field was decorative, and the 7 hosts configured
'basic' (cursor, slate, kiro, opencode, openclaw, hermes, gbrain) silently
received the 'full' cross-project flow their runtimes can't execute (it
depends on AskUserQuestion + gstack-config plumbing). Output now matches
declaration: basic hosts get the project-scoped search block.

Blast radius proof: all committed Claude SKILL.md files and the three golden
fixtures are byte-identical; the behavior diff lands only in the gitignored
external-host trees (hand-verified: .cursor review's learnings section swaps
the cross-project AskUserQuestion block for the project-scoped search).

* fix(gen): small config scrubs — openclaw blobs to real files, setup host drift, dead artifacts

- The three openclaw markdown blobs hardcoded inside gen-skill-docs.ts (which
  silently reverted any hand edit to their tracked outputs on regen) move to
  openclaw/templates/*.md source files; output shasums byte-identical.
- setup's --host allowlists gain cursor + slate — both fully registered hosts
  with generated output, but './setup --host cursor' exited 1 because two
  hand-rolled lists in setup had drifted from hosts/index.ts.

  Recoverable from git if ever wanted under a non-colliding name.

* feat(gen): correct preamble tiers for the 8 silently-heaviest skills

With tiers now explicit, set them RIGHT by analogy to the tiered population:
scrape/diagram/open-gstack-browser (+ the connect-chrome symlink) -> tier 1
(launchers and artifact generators, like browse and make-pdf);
landing-report/pair-agent/skillify -> tier 2 (dashboards and session tools,
like health and canary); spec -> tier 3 (interactive planning, like the
plan-*-review family). Each tier-1 skill sheds 271 lines of onboarding
prose it never needed; tier-2 shed 20 each.

Verification per the review protocol: regen diff reviewed (pure
section-removal), skill-validation + size-budget + catalog-budget +
v0-dormancy suites green (822 tests), and live smoke of the tier-corrected
skills confirms the preamble renders the intended sections at each tier.
These skills have ~no eval coverage — stated honestly; the wave's gate-tier
eval run is the backstop.

* feat(test): e2e-gate — one tier-gate implementation, side-effect-free, with the trap pinned

The EVALS/EVALS_TIER gate was copy-pasted into ~40 test files and had drifted
into six different predicates — the drift that made 'eval:bg:all runs
everything' silently false. test/helpers/e2e-gate.ts owns the semantics now:
describeE2ETier(tier) + e2eTierEnabled(tier), env read at call time, zero
side effects (the existing e2e-helpers module runs a ~30s claude ping at
import under EVALS=1, so the gate lives in its own module; purity is pinned
by tests that scan imports and comment-stripped source).

The unit matrix pins all four env combos — including EVALS=1 with EVALS_TIER
unset -> SKIP, the exact trap that made eval:bg:all a non-run. The
tier-alignment tripwire gains a second regex for the helper shape (old shape
still detected — stragglers can't hide), and the sharded paid runner's
PRE-SPAWN tier classifier learns the helper shape too: without that, every
gate-sharded run would have spawned all 28 periodic shards just to skip them,
each paying the e2e-helpers import ping (~15 min of dead wall clock in the
CI-blocking lane). Verified: gate runs exclude the 29 periodic files,
periodic excludes the 8 gate files — identical to pre-migration.

* refactor(test): migrate the 36 tier-gated eval files to describeE2ETier

Mechanical two-liner swap in 34 files (each keeping its declared tier — all
36 predicates verified against E2E_TIERS before migrating); the two files
with compound gates (overlay-harness's EvalCollector feed, codex-e2e's
CODEX_AVAILABLE) keep their extra conditions via e2eTierEnabled. Tier
rationale comments preserved. codex-e2e/gemini-e2e/benchmark-providers keep
their distinct stderr-message gate shapes by design.

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

* refactor(test): skill-e2e + skill-llm-eval adopt the shared selection machinery

Both files re-implemented the diff-selection machinery e2e-helpers already
exported. The helper gained computeDiffSelection() (extracted, identical
behavior) and a trailing optional selection param on the *IfSelected helpers
(defaults preserve all 30+ existing importers). skill-e2e.test.ts drops ~120
duplicated lines; skill-llm-eval keeps its LLM_JUDGE_TOUCHFILES selection and
test.concurrent semantics via testConcurrentIfSelected.

Deliberate deltas, stated: skill-e2e.test.ts now honors the EVALS_TIER
intersection its local copy lacked (affects only direct bun test invocations
of that file — it matches no eval-script glob); its recordE2E gains the
helper's three diagnostic fields; skill-llm-eval sharded solo now runs
e2e-helpers' module-scope preflight it already ran in combined processes.

* fix(test): kill the silent-truncation race; exempt the tier-corrected shrinks

The full-suite shakeout (budgeted by the plan) surfaced both immediately:

1. server-embedder-terminal-port.test.ts stubbed process.exit and restored
   the REAL exit in its finally — but shutdown() schedules async work that
   can call process.exit AFTER restoration, killing the entire bun process
   mid-suite with exit 0 and NO summary. This is the silent-truncation class
   the new free-suite CI job guards against, reproduced locally on the first
   full run. Exit now stays a logging no-op between tests (late async exits
   become visible stderr lines, not process death); the true exit returns in
   afterAll.

2. The 80%-of-baseline shrink guard correctly flagged the six tier-corrected
   skills — their baseline was measured at the silent tier-4 default. Added
   to INTENTIONAL_SHRINKS with the reason, joining spec's double-preamble
   entry.

* release: v1.64.0.0 — the code-smell fix wave

35 commits, one PR: guard repairs (free suite in CI per-file, all-host
freshness gates, tunnel allowlist, diff-selection validation), the
sidebar-agent ghost exorcism (dead ML layers, dead endpoints, dead exports,
ghost comments), config honesty (defineHost factory, dead fields deleted,
preamble tiers explicit, spec double-render fixed), and dedup with safety
nets (session-cookie factory, fs-atomic, jsonl-store contract, one eval
tier-gate). Net -24,943 lines across 183 files.

* fix(ci): free-tests step runs under bash (container sh rejects pipefail)

Maiden-voyage shakeout, exactly as budgeted: the CI container's default
shell is dash, which errors on 'set -o pipefail' before the first test ran.

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

* fix(ci): free-tests curates 8 container-incompatible files with reasons

Second maiden-voyage shakeout round: 376 of 384 files ran green in the
container on the first completed pass. The 8 that can't run there yet are
excluded the same way the Windows shards curate POSIX-bound files — each
with its reason inline (headed-Chrome handoff, real-PTY round-trip, X server
management, extension-origin identity, the job's own TMPDIR override, and
three pre-existing env failures that fail on dev machines too). Anything
outside the list that fails still fails the job; trimming the list is
tracked follow-up.

* fix(test): gstack-config-key-locale — suppress the skill_prefix auto-relink side effect

The test invokes the repo's own bin/gstack-config, whose 'set skill_prefix'
auto-runs $(dirname $0)/gstack-relink — resolving the install dir to the
repo itself. In any environment where the loop shares a working tree (the
free-tests CI container, a fresh-HOME run), gstack-patch-names rewrote all
52 tracked SKILL.md names to gstack- prefixed, poisoning five unrelated
suites downstream (hermetic-skills-seeding, host-config golden, skill-census,
skill-validation, spec-template-sync). GSTACK_SETUP_RUNNING=1 is the
documented suppression; relink behavior stays covered by relink.test.ts's
mock install.

* fix(bin): gstack-codex-session-import — empty sessions dir exits 0 on Linux

GNU xargs runs 'ls -t' once even on empty input, listing the cwd and
producing a bogus LATEST from the repo root; BSD xargs (macOS) skips the
run, which is why the NO_SESSIONS path only broke on Linux. xargs -r pins
the BSD behavior on both platforms.

* test(parity): rebaseline v1.57.7.0 → v1.64.1.0 + skeleton-cap headroom

The two parallel v1.64 waves (code-smell fix wave + main's garrytan#2571) each
added shared-preamble prose, pushing document-release / design-consultation
/ cso past their size ratios on the v1.57.7.0 anchor and four carved
skeletons (plan-ceo-review, plan-eng-review, office-hours,
design-consultation) 22-280 B over their absolute caps. New baseline is
union-normalized (skeleton + sections/*.md, matching what the harness
measures); caps get +~1 KB headroom each with per-cap rationale. The
v1.57.7.0 fixture stays in test/fixtures/ for the audit trail, and
capture-parity-baseline.ts now documents the union-normalization step so
the next rebaseline doesn't re-trip on it.

* fix(ci): free-tests container parity — tools, pinned bun, git identity, mutation tripwire

- Dockerfile.ci: add python3 (gstack-jsonl-merge/brain-sync/detach shell out
  to it), file (skill-validation's binary check), poppler-utils (make-pdf
  e2e gates hard-require pdftotext/pdffonts/pdfinfo), fonts-noto-color-emoji
  (emoji render gate, mirrors make-pdf-gate.yml). Fix the bun pin: the
  bun.sh installer ignores a BUN_VERSION env var, so the old form silently
  installed latest on every rebuild (observed 1.3.13/1.3.14 drift vs the
  1.3.10 devs run locally); pass the version as the positional arg.
- free-tests.yml: git identity + safe.directory for the git-exercising
  tests (container checkout is owned by a different uid than runner);
  post-loop tree-mutation tripwire that names a tracked-file-mutating test
  instead of letting downstream collateral confuse the report; skip the
  documented variants-retry-after timing flake.

* fix(bin): gstack-session-update — detached updater owns its stdio (SIGPIPE)

The backgrounded update subshell inherited the session hook's stdout/stderr
pipes. Once the hook exits and the caller closes them, any child that writes
— git pull's autostash notice, setup output — dies of SIGPIPE, logged as
PULL_FAILED exit=141 with an empty stderr capture (observed in the free-tests
container, and reachable by any production hook runner that closes stdio
promptly). Redirect the fork to /dev/null; all observability already flows
through the session-update log file.

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

* fix(test): gstack-decision-bins — explicit branch context for the scope filter

CI checks out a detached HEAD, where gitBranch() returns undefined on both
the log and search sides, so an implicitly branch-scoped decision can never
surface (filterByScope requires a matching non-empty ctx.branch). Pass the
branch explicitly on both sides — the filter logic is what's under test, not
git branch detection.

* fix(test): ring-buffer lease interplay — same TTL window, not same millisecond

Two back-to-back mintLease() calls each stamp Date.now() + TTL; when they
straddle a millisecond boundary the exact-equality assertion flakes
(observed in CI: expiries of ...525 vs ...526). Assert the expiries are
within a 50 ms window instead — the invariant under test is that leases
share a TTL policy, not that they mint in the same clock tick.

…bles skills, brain-cache honest-missing fix, ship v1.1.0 lint gate

Re-port of the pre-upgrade local commits (preserved at local-fixes-pre-1.64)
onto upstream v1.64.1.0, final-state port + regen rather than cherry-picks:

- autobuilder-loop/ and plan-deliverables/ SKILL.md.tmpl at their final
  pre-upgrade state (v1.6.1 / v1.2.0, both preamble-tier: 3), including the
  adversarial-forum effort ladders and error-class-aware retry
- bin/gstack-brain-cache: local decisions.active.json ledger for
  recent-decisions; honest 'missing' instead of fabricated-empty on gbrain
  failure (upstream never touched the file — clean port)
- ship v1.1.0: lint+typecheck gate in Steps 5/16, hardened
  bin/gstack-lint-touched + contract test (heals the live PostToolUse hook
  in ~/.claude/settings.json that dangled since the reset)
- v1.64.1.0-era registrations the old commits predate: skill-coverage-matrix
  entries, AGENTS.md + docs/skills.md doc-inventory rows, catalog-budget
  ratchet 1150 -> 1250 (measured 1203; derivation comment updated per
  RATCHET_PROTOCOL). proactive-suggestions.json hunks dropped (retirement
  is CI-pinned).
- preamble carve (5422e28) deliberately NOT ported in this wave.

… + Grok, union gate FAIL -> all P1s fixed)

Adversarial review of the restoration commit by both external CLIs per the
autobuilder-loop forum recipe. Every [P1] fixed, cheap [P2]s included:

P1 (found by both models independently):
- plan-deliverables: {{BENEFITS_FROM}} prose reference expanded the whole
  Prerequisite Skill Offer block mid-sentence in generated output,
  contradicting the surrounding stop-if-no-design-doc rule -> braces dropped
- brain-cache: local decisions ledger rendered decision/scope/date into the
  planning-skill digest without datamark() (gstack-decision.ts documents
  snapshot reads as datamark-required) -> datamark at render + regression test
- config gates compared against literal 'on'/'off' while gstack-config's
  vocabulary is enabled/disabled (unset keys return empty, exit 0) -> both
  members self-classified ABSENT on every default install; now explicit-
  negative gating in both skills' recipes

P1 (Codex): plan-deliverables gap-check had the agent paste doc-derived text
  inside a quoted heredoc — a doc line equal to the terminator executes the
  rest as shell -> untrusted text now travels as a Write-tool file; only the
  agent-chosen path is substituted into the script; skip-guard keys on the
  appended fences

P1 (Grok) / P2 (Codex): autobuilder-loop {{REVIEW_ARMY}} prose reference
  pasted the full Review Army dispatch into the SKIP-instruction parenthetical

P2 hardening: lint-touched array-built command (spaces in ROOT), leading-dash
  file_path guard, biome >=2 crash fail-open parity; brain-cache Array.isArray
  payload guard + slug traversal reject; /autobuilder-loop registered in
  CLAUDE.md tree+routing and README (gap in the original July commits).

Deferred (design-level, documented in session report): ledger-priority vs
brain-cache-spec drift, ship Step 5 bunx/script-detect/exit-join, autobuilder
SHIP_METER cat flags + status-machine resume gaps, e2e floor-only coverage.

…~/.claude ban

The skill-seeding tripwire asserted every seeded symlink target must NOT
start with ~/.claude — but on the default global-git install the repo
itself lives at ~/.claude/skills/gstack, so every CORRECT symlink (which
must resolve into the live repo tree, as the very next assertion requires)
carried the banned prefix. The test could never pass on a default install:
pristine v1.64.1.0 (c118e24) fails it in any worktree under
~/.claude/skills/ and passes elsewhere (verified 2026-08-15).

Exempt targets that realpath into the resolved repo ROOT before applying
the operatorClaude ban — realpath both sides so a symlinked HOME can't
dodge the tripwire. Genuine escapes (a target under ~/.claude but outside
the repo) still fail with the escape message.

…efactors

All three failed deterministically on PRISTINE v1.64.1.0 (c118e24) on any
machine that actually runs them; upstream CI never sees the first because
it skips without Playwright chromium installed.

- compare-board.test.ts: the v1.64 signature-bridge wrapper for
  handleReadCommand dropped its 4th argument (the BrowserManager), so the
  now-unconditional JS-origin assertion TypeError'd on bm.hasCookieImports()
  — all 16 tests. The sibling write bridge two lines down had it right.
- extension-sender-auth.test.ts: the behavioral 'gate answers' loops
  iterated 'sidebar-command', which background.js no longer routes (dropped
  from ALLOWED_TYPES with the chat rip) — the listener goes silent on
  unknown types BEFORE the sender gate. Routed types keep the answers
  assertion; 'sidebar-command' keeps a nothing-usable-leaks check.
- security-sidepanel-dom.test.ts: five tests drove the shield/banner off
  the ripped chat path; the first waited 15s for a data-status that never
  arrives, and bun's timeout handler SIGTERM'd the SHARED beforeAll browser
  (exit 143), cascading 'browser has been closed' into the rest. Replaced
  with pins of the current contract (shield exists, stays hidden, stays
  undriven) plus a tombstone for resurrecting the old cases if the shield
  is ever re-driven.

…y preamble sections, Claude host only

Full port of the shared-preamble carve (5422e28, preserved on
local-fixes-pre-1.64) per the restoration audit's file map. Upstream
v1.62-v1.64.1 never built an equivalent: main still composed the full
inline preamble per skill.

Mechanism: tier-2+ Claude-host skills get a '## Preamble Section Index'
pointing at shared preamble/sections/{onboarding,ask-user-questions,
artifacts-sync}.md (one copy for the whole suite, read on demand via
{{PREAMBLE_SECTION:id}} / carved-sections.ts). Every other host keeps the
full inline preamble. bin/gstack-artifacts-preamble carries the always-run
artifacts-sync bash (KEEP-IN-SYNC with generate-brain-sync-block.ts).

Ported with the audit's adaptations:
- KEPT upstream's mandatory preamble-tier throw (no '?? 4' fallback)
- brain-sync arithmetic guard + _GBRAIN_HOST sanitize applied on top of
  upstream's quoteSafePath (also PR'd upstream separately as garrytan#2588)
- toYamlInlineScalar '...' quoting + catalog-trim coverage (also garrytan#2589)
- deleted dead generate-writing-style-migration (WRITING_STYLE_PENDING was
  never echoed); migration v1.0.0.0.sh rewritten to a one-line notice
- bin/gstack-config explain_level honesty block re-anchored into the
  refactored set path
- autoplan lazy per-phase review-skill loading merged with upstream's
  scope-gate skip line
- carve-guards floors re-derived from the post-carve regen (design-
  consultation 52k/69k, cso 58k/68k measured 2026-08-15), NOT copied
- fresh parity baseline parity-baseline-v1.64.1.0-carve.json captured and
  union-normalized for the 9 carved skills; skill-size-budget and
  parity-suite repointed
- ship goldens re-blessed; regen verified 0 STALE across all 10 hosts;
  non-Claude hosts confirmed inline (with the arithmetic guard); tier-1
  index confirmed AUQ-row-free, tier-3 carries it

Verification: 638 carve-critical + 778 adjacent tests green.

…ough _receipted_git

The garrytan#48 carve port moved the daily GSTACK_HOME fetch out of agent-executed
skill prose (exempt: agent-typed) into a real auto-run binary — a genuine
egress sink the NEW-SINK SCANNER correctly flagged. Wired fail-closed with
brain-sync's own sink name and polarity (same operation, relocated); the
--ff-only merge now runs only after a successful receipted fetch. Registered
in SHELL_SINKS per the test's protocol; the prose exemption note narrowed to
non-Claude hosts.

Found by the CI-parity per-file suite (shard 9) during carve-port verification.

…handleReadCommand bridge (same class as compare-board)

Upstream v1.64.1.0 changed handleReadCommand's signature to (command, args, session, bm), but this file's local bridge still called it with the old 3-arg shape, leaving bm undefined. read-commands.ts:186's now-unconditional JS-origin assertion then TypeErrors on bm.hasCookieImports(), which is exactly the bug already fixed in compare-board.test.ts (8a37d90).

…r rides milestone commits; lint-touched detects flat eslint configs

- autobuilder-loop/SKILL.md.tmpl: add a one-time Worktree preflight gate at
  loop kickoff (step 0, before any milestone work). If `git status
  --porcelain` is non-empty, AskUserQuestion ONCE — stash unrelated changes
  (recommended), proceed with explicit consent, or abort — so a dirty
  worktree's unrelated/secret files never ride the loop's first `git add -A`
  milestone commit into review/ship. Adds a reconciling sentence at the
  milestone-commit site: the preflight-clean start is what makes `-A` safe
  there; the general rule against blind `git add -A` elsewhere still holds.
- bin/gstack-lint-touched: fix eslint config detection. `ls
  "$ROOT"/.eslintrc* "$ROOT"/eslint.config.*` exited non-zero whenever EITHER
  glob had no match (the unmatched glob passes through literally and ls
  errors on it), so a repo with only flat config (eslint.config.js — the
  modern majority) silently skipped linting. Now detects each config family
  independently via a bash-3.2-safe loop.
- test/gstack-lint-touched.test.ts: add a regression case — a repo with only
  eslint.config.js (+ an executable node_modules/.bin/eslint stub) must run
  the linter.

…amble + brain-sync prose (control-line forgery)

P1: _BRAIN_LAST_PUSH and _BRAIN_NEW_URL in bin/gstack-artifacts-preamble were
interpolated into agent-consumed ARTIFACTS_SYNC control lines with no defense
against multi-line/control-char values from the git-synced ~/.gstack tree;
first-line-only + charset/length caps now apply, plus a numeric guard on
_BRAIN_QUEUE_DEPTH. Mirrored into the KEEP-IN-SYNC prose twin
(generate-brain-sync-block.ts) since non-Claude hosts execute that rendered
bash and share the same forgery surface.

P2-a: the last-pull cooldown stamp now only writes on a successful receipted
fetch, so one failed fetch no longer silences pulls for 24h.
P2-b: the GBrain-tip grep -c pattern no longer doubles its own "0" output via
a redundant `|| echo 0`, which broke the numeric comparison.
P2-c: bin/gstack-brain-cache now datamark()s free-text title/slug fields and
projectSlug digest headers in fetchGoals/fetchRecentDecisions/fetchSalience's
gbrain-served content before it lands in agent context.
