Garry Tan df89475b17 v1.91.11.0 refactor: one state-root rule, browse route table, shared shard engine, PTY harness split, MECE review resolvers (#3002)
* refactor(resolvers): split review.ts into MECE resolver modules (pure move)

Move every function from scripts/resolvers/review.ts, unchanged, into:
- review-dashboard.ts: review dashboard, plan-file review report
- plan-gates.ts: approval check, exit-plan-mode gate, plan-file discovery,
  plan-completion audit/gate (ship + review), plan verification exec
- spec-review.ts: both spec review loops, benefits-from, anti-shortcut clause
- outside-voice-steps.ts: Codex second opinion, adversarial step, Codex plan
  review, Codex doc review, disabled-outside record
- review-scope.ts: scope drift, cross-review dedup, shared-code reuse

review.ts is deleted; index.ts imports the new modules. gen-skill-docs
output is byte-identical for every host (--host all). Test imports and
source-path references are re-pointed; the two source-text report/gate
tests in gen-skill-docs.test.ts become behavioral renders across every
consuming skill and host. All 46 touchfile entries that named review.ts
now name all five modules, guarded by a recorded selection golden.

* test(browse): black-box auth matrix for every server route and both surfaces

Drives buildFetchHandler fetchLocal/fetchTunnel with no token, wrong token,
root token, scoped token and the SSE cookie for all 33 routes, plus unmatched
paths and wrong methods. Denials assert today's exact status, body and content
type; allowed credentials assert the handler was reached. Written against the
unchanged if-chain server so the W3 route-table refactor must keep it green.

* refactor(shard-engine): move scripts/test-strict-output.ts to scripts/lib/shard-engine.ts

The shared shard engine grows from the existing strict-output module
(runShardChild, killProcessGroup, signal forwarding, strict classifier).
scripts/test-strict-output.ts stays as a re-export so existing importers,
mock.module paths and the strict-output/run-shard-child tests are unchanged.
The engine inherits the global touchfile entry; the free runner's CLI-routing
fixture copies the new module.

* refactor(resolvers): decompose the three >150-line review resolvers (output-neutral)

Split generateAdversarialStep, generateCodexPlanReview and
generatePlanCompletionAuditInner into per-section helpers whose template
literals are copied verbatim, so every function in the new modules is at
or under 150 lines. gen-skill-docs output is byte-identical for every host
(--host all, compared against 96764e80 with a fixed --link-root).

* refactor(resolvers): one outside-voice failure policy (deliberate prose unification)

outsideVoiceFailurePolicy(ctx, opts) in outside-voice.ts now renders the
auth / timeout / empty-response bullets for all four call sites that
hand-typed them (Codex second opinion, adversarial step, Codex plan
review, design outside voices). Options are explicit per site
(timeoutMinutes, onTimeout, stderrOnEmpty, fallback, escape) with no
defaults.

Deliberate generated-prose changes (every host):
- office-hours: 'Fall back to <native> subagent.' becomes
  'Fall back to the <native> subagent below.'
- plan-devex-review: the plain 'Auth failure (stderr contains ...)'
  bullets become the canonical bold bullets; auth also triggers on
  'API key'; 'auth failed' becomes 'authentication failed'.
- review/ship adversarial: 'exceeded 9 minutes and was terminated'
  becomes 'timed out after 9 minutes and was terminated'; the timeout
  is still MISSING COVERAGE.
- design outside voices: unchanged.

Adds ratchet (d) (test/outside-voice-failure-policy.test.ts) with a
reasoned allowlist for /codex's own CLI errors, the MISSING COVERAGE
retention test, refreshed codex/factory ship goldens, and outside-voice.ts
in every touchfile entry of review.ts and design.ts (selection golden
extended).

* test(pty): fake PTY session driver with an injectable clock through the runner launch seam

The three plan-skill runners take an optional PtyDriver (launch, now,
monotonic, sleep); omitted, they use the real launcher and clocks exactly as
before. test/helpers/pty/fake-session.ts feeds scripted frames through that
seam, and claude-pty-runner.runners.unit.test.ts runs observation, counting
and floor for success, deadline timeout, permission prompt and plan-ready
outcomes with no CLI or real timers. These cases must stay green unchanged
through the W4 split and the runPtySession extraction.

Touchfiles: every entry that lists claude-pty-runner.ts or pty-screen.ts now
also lists test/helpers/pty/**.

* refactor(shard-engine): run both lanes on the shared engine; lane policy injected

Engine (scripts/lib/shard-engine.ts) gains the W2 primitives: per-shard
tmp/Chromium sandbox + async cleanup backstop, log-path allocation and
full-stream log capture, one duration-seed reader/writer with a lane
predicate, LanePolicy (seed predicate + zero-execution verdict),
strictShardStatus, and the shared CLI flag loop. runShardChild takes an
optional companion (signal/settle) and waits a bounded 250ms to reap a
wall-killed child.

Free lane stops spawning shards itself: runFreeShard uses runShardChild
with trackShardBrowser as the companion (win32 path unchanged: no process
group, no negative-pid kill). Its sync state-dir removal stays lane policy.
Paid lane uses the sandbox, log, seed, verdict and flag primitives; the
hollow-shard guard applies PAID_LANE_POLICY. Lane outcomes are unchanged
(free keeps >= 0 seeds and file-count zero-exec rule; paid keeps > 0 seeds,
warning under selection and passed-empty under EVALS_ALL).

paid-free-boundary's closure assertion now names the engine module, where
the strict classifier lives.

* test(shard-engine): engine unit tests, fixture-corpus equivalence, per-lane CLI parity

- test/shard-engine.test.ts: failing/unhandled/module-load output fails both
  lanes, per-lane zero-execution and seed rules, whole-group kill on a wall
  timeout (both lanes), mocked-win32 path with no negative-pid kill,
  companion settle order, log capture, sandbox isolation, flag loop.
- test/shard-engine-equivalence.test.ts + test/fixtures/shard-equivalence:
  seven outcome fixtures plus one real shard, run through both lanes and
  compared with classifications recorded from the base runners (96764e80).
- test/shard-cli-parity.test.ts + test/fixtures/shard-cli-parity: flag set,
  defaults, validation errors and the Unknown argument error per lane match
  the base runners.

* refactor(shard-engine): decompose runFreeShard and runPaidShard to <= 150 lines

Output-neutral extraction under the fixture-corpus equivalence and runner
tests: captureFreeStream, explainFreeVerdict and logFreeRecovery (free);
paidShardCommand, settleShardSpool, settleBootstrapRetention and
printLogTail (paid). The bootstrap scope-creation block that
bootstrap-retention.test.ts evaluates stays verbatim.

* refactor(pty): split claude-pty-runner.ts into test/helpers/pty/* behind a barrel

Pure move: every line of the former 5,047-line runner lands verbatim in one
module (four private helpers gain `export` for cross-module use):
binary, screen (absorbs test/helpers/pty-screen.ts, which now re-exports it),
launch, session (PtyDriver), judge, classify, auq, plan-native, boundaries,
runners/{observation,counting,floor}. claude-pty-runner.ts re-exports the
original public surface by name; pty/ modules import siblings directly.

Tests that read the runner's source text:
- rewritten as behavioral: the unit test's model-pin tripwire (fake CLI argv:
  fallback chain, --model before extraArgs, hermetic --strict-mcp-config),
  pty-skill-seeding-wiring (runners through the fake driver; launcher through
  a fake CLI reporting CLAUDE_CONFIG_DIR). The "three wrappers forward model"
  grep is replaced by the runners' fake-driver launch assertions.
- pty-screen-session / pty-screen-supervision: stop copying runner source;
  they mock.module the real pty/screen.ts (and the fixture cleanup) instead.
- re-pointed to the owning module (they execute a sliced runner body with
  injected boundaries; no seam exists for those boundaries yet):
  eng-seeded-completion-ai, plan-floor-permission, plan-create-prepublication,
  plan-count-completion; hermetic-wiring's source guard now reads pty/launch.ts
  and scans every pty/ module for raw process.env spreads.
- plan-count-timeout and pty-output-wake mock the viewport at pty/screen.ts.

* test(ratchet-c): enforcing module/function size ratchet and moved-code touchfile coverage

Ratchet (c) ships enforcing: test/helpers/module-size.ts counts file and
top-level function lengths by brace matching over masked source (strings,
comments, regex literals and template text masked; ${} expressions kept),
covering function declarations, arrow functions assigned to consts and
route-table handler properties, with no parser dependency. Its self-test
uses template literals and code-fence braces copied from
scripts/resolvers/review.ts and design.ts. test/fixtures/module-size-ratchet.json
binds scripts/lib/shard-engine.ts (<= 800 lines, <= 150 per function) and
records the residual runner sizes (free 2352, paid 1921) as non-growth caps;
allowlist entries are keyed on file plus matched text and need a reason.
Failure output lists file:line, the rule, Fix: and the allowlist path.

touchfiles.test.ts gains the moved-code superset check over
test/fixtures/touchfile-move-goldens/ (W2 golden recorded at 96764e80:
test-strict-output.ts and test-paid-shards.ts global, test-free-shards.ts none).

* refactor(browse): declared route table replaces the buildFetchHandler if-chain

The ~1,300-line if-chain in buildFetchHandler becomes a route table:
each entry declares method, path, auth kind and surfaces, and one auth
gate in browse/src/routes/table.ts returns the per-kind denial (root-bearer,
scoped, root-or-sse-cookie: 401 Unauthorized; root-token: 403 Root token
required; extension-origin: 403 Forbidden). Unmatched requests take the
declared fallthrough (root-bearer check, then plain-text 404). Handlers move
to browse/src/routes/{core,pairing,pty,tokens,tunnel,activity,commands,files,
inspector}.ts and receive a RouteContext with auth checks as functions
instead of closing over factory locals. Dispatch order is unchanged:
tunnel filter, beforeRoute overlay, gate, handler. TUNNEL_PATHS stays a
literal in server.ts.

Behavior-preserving: the black-box auth matrix from the previous commit
passes unchanged. /memory and /inspector/events are declared root-bearer
because the blanket check always ran before their SSE-cookie branch.

Source-text route tests are rewritten as behavioral tests through
buildFetchHandler or a route's real handler with a stub RouteContext
(browse/test/route-test-harness.ts). Checks with no runtime seam are
re-pointed to the route modules: Surface type, /inspector/events SSE
helper, sanitizeReplacer imports, /pty-inject-scan sidecar-client import,
and the ngrok config lookup and startTunnel wiring that stay in server.ts.

* test(browse): stubbed-handler auth matrix and route inventory for the route table

Every ROUTES entry runs through the real dispatcher and gate with stub
handlers on each declared surface and six credentials; denials assert the
exact status and body each auth kind returned at 96764e8, admitted
credentials assert the handler ran (with the gate's TokenInfo for scoped
routes). Also pins the reviewed route inventory (method, path, auth kind,
surfaces), that every entry declares auth and surfaces, that the table's
tunnel paths equal the TUNNEL_PATHS literal with GET /connect admitted, the
unmatched fallthrough, and that the root token is rejected on every tunnel
route through buildFetchHandler.

* test(browse): ratchet (b) keeps route dispatch inside the route table

Scans browse/src/server.ts and browse/src/routes/*.ts for pathname
comparisons; only the table matcher and the tunnel-surface filter are
allowed, listed with reasons in browse/test/fixtures/route-dispatch-allowlist.json
(keyed on file plus line text). Also checks every entry declares auth and
surfaces and that gstack registers no beforeRoute overlay itself. Self-tests
plant a violation and assert the file:line, Fix: and allowlist path in the
message, that a shifted line stays allowlisted, and that a reasonless entry
is rejected.

* test: touchfile superset check for modules moved out of browse/src/server.ts

Records the paid evals selected by touching browse/src/server.ts at 96764e80
(17 E2E, 1 LLM judge) and asserts every browse/src/routes/*.ts module selects
a superset. The test reads every golden in test/fixtures/moved-module-selection/
so other moved-code goldens can sit beside it.

* test(shard-engine): give non-timeout corpus fixtures CI headroom; keep the POSIX golden off the Windows lane

Only the wall-timeout fixture keeps a 3s wall; the rest get 60s so a loaded
host cannot turn a pass into a timeout. Base and branch runners still agree
on every classification under the new walls. The Windows exclusion entry
moves the free runner's ratchet (c) residual cap to 2356 lines.

* refactor(pty): one runPtySession loop drives observation, counting and floor

test/helpers/pty/session.ts owns launch -> start -> (poll -> tick)* ->
timeout and the failure contract the three runners each hand-rolled: the
run's own error wins over capture and close errors, close always runs, owned
fixture cleanup runs last (also when launch fails). Each runner now supplies a
PtySessionPlan: its boot/command step, poll cadence (2s observation/floor
sleep; counting's output wake + 250ms coalesce), tick policy (permission
handling, native identity, terminal rules stay per runner because they differ)
and capture hooks. The runner bodies are decomposed into top-level steps so no
function exceeds 150 lines; behavior is unchanged and the fake-driver cases
from the first W4 commit pass unmodified.

The counting capture step and the native completion-summary predicate are now
named functions (countingCapture, isNativeCompletionSummary), so
plan-create-prepublication and plan-count-completion call them directly
instead of executing sliced source. The two harnesses that still execute a
sliced runner body with injected boundaries (eng-seeded-completion-ai,
plan-floor-permission) pass the PtyDriver seam instead of overriding
Date/Bun.sleep.

* test(ratchet-c): register route modules, review resolver modules and server.ts residual cap

* refactor(pty): decompose launchClaudePty and engNumberedFindingAUQ under 150 lines

launchClaudePty (349 lines) becomes launch preparation (args, hermetic
child env, owned state roots), recorder creation, spawn, the trust-dialog
watcher, close, and the session handle over one PtyProcess state object. The
failure order is unchanged: abort the viewport, dispose any recorders created
so far, dispose the viewport, rethrow. The --model / --strict-mcp-config
ordering and seedSkills wiring stay pinned by the behavioral fake-CLI tests.

engNumberedFindingAUQ (345 lines) keeps its guards and dispatch; each
self-contained issue family (declared cache, library retry hooks, cache
owner, injected singleton, shared writers, injected export) moves verbatim
into its own function. Every pty/ module is now <= 800 lines and every
top-level function <= 150 lines.

* test(pty): split claude-pty-runner.unit.test.ts along the pty/ module seams

The 188 unit tests move verbatim into claude-pty-runner.{screen,classify,
auq,launch,plan-native,boundaries}.unit.test.ts (test names unchanged; each
file imports only what it uses from the barrel). The five files that no longer
read a SKILL.md template join the test-of-test ratchet baseline with a reason.

* test(touchfiles): moved PTY modules keep their paid-eval selection

test/fixtures/touchfile-selection/w4-pty.json records, at 96764e8, the paid
evals selected by touching test/helpers/claude-pty-runner.ts (20) and
test/helpers/pty-screen.ts (20). touchfiles.test.ts now asserts every .ts file
under test/helpers/pty/ (and pty/screen.ts for both sources) selects a
superset, reading every golden in that directory so later moves can add one;
a planted-violation case pins the report and its Fix line.

* fix(browse): unexchanged pair setup keys no longer authenticate bearer requests

validateToken accepted a gsk_setup_ key as a bearer on /command, /batch and
/file (found while building the W3 auth matrix). A setup key now only
authenticates the /connect exchange.

* W1: one state-root owner (lib/state-root.ts + bin/gstack-state-root.sh), gstack-paths --explain and fail-stop, parity tests

* W1: guarded migration of every executable state-root site; uninstall deletes only ~/.gstack

Bins, careful/freeze hooks, setup, upgrade migrations, browse/src, design,
ios-qa daemon, lib and scripts resolve the state root through
bin/gstack-state-root.sh (bash) or lib/state-root.ts (TS). Bins source the
twin and stop with a reinstall message when it is missing; hooks source it
and never spawn gstack-paths. browse/src/config.ts and lib/cso/state.ts
delegate to resolveStateRoot. Analytics writers and readers move together
so the usage log stays one file. gstack-uninstall deletes state only at
~/.gstack, refuses (exit 2) when it resolves to /, $HOME or an ancestor,
the checkout or the git root, and leaves any other resolved root in place
with the removal command. Fixtures that copy single bins now copy the twin.

* W1: privacy keys and trust-policy deny tiers merge across state roots; gstack-config reporting; test hermeticity

readConfigKey / gstack_read_config_key return the most restrictive
telemetry, memorable_recall, codex_reviews and update_check across the
resolved root and ~/.gstack; other keys read the resolved root only.
gstack-config set reports an overriding root with the exact override
command, list shows the winning root and a root-variable disagreement line.
gstack-gbrain-repo-policy get merges deny/read-only tiers. gstack-egress
reads through readConfigKey. test-setup.ts strips inherited
GSTACK_STATE_ROOT/GSTACK_STATE_DIR and redirects the legacy root.

* W1: shared hook logging helper (hosts/claude/hooks/hook-log.ts)

One hook-errors.log writer: root from resolveStateRoot, 0600 on every
append, opt-in rate limit used only by memorable-user-prompt. The five
hooks route through it.

* W1: docs/state-root.md and README troubleshooting pointer

Precedence table, a real --explain example, the move-your-state recipe,
merged privacy keys, the uninstall rule, the resolver-failure fix, and the
plugin-mode note (evidence gate: no official plugin distribution).

* W1b: template and resolver prose resolve state through guarded gstack-paths; ratchet (a)

Every gstack-paths eval in templates and resolvers carries the fail-stop
guard; executable ~/.gstack paths in bash blocks (context recovery preamble,
eureka log, analytics, project artifacts, upgrade snooze, setup-gbrain lock,
retro snapshots, ship consent marker) use $GSTACK_STATE_ROOT, and the writer
prose that pairs with them points at the printed PROJECT_DIR / RETRO_FILE.
ship drops export GSTACK_STATE_ROOT. SKILL.md regenerated (claude + codex),
ship goldens re-pinned, parity and context-budget caps raised to the measured
sizes with notes. test/state-root-ratchet.test.ts enforces the rule with a
reasoned allowlist; W1 touchfile entries plus a superset golden.

* refactor: apply W1 state-root edits in W2/W3/W5-owned files; one moved-code touchfile golden for all workstreams

* test: fold the moved-code touchfile golden into touchfiles.test.ts; fix integration fixture closure and caps

* v1.91.11.0: CHANGELOG, TODOS, docs and conventions for the refactor wave

* test: re-measure plan-ceo/design-consultation caps and ship goldens after the guarded plan-discovery and spec-review blocks; add the state-root twin to the workflow-boundaries fixture

* fix(windows): migrations resolve their directory with either path separator; state-root parity compares under the HOME Git Bash actually sees

* fix(review,ship): state plan-check timing after smoke expiry and test_stub Skip semantics (review workflow judge clarity)

* test(qa-eval): webhook fix eval asks for the fix loop's post-repair probes; eight-scenario coverage stays in the report-only case and the harness recheck

* test(qa-eval): re-pin the webhook prompt contract to the fix-loop stage; R29 coverage omissions stay bound by the report-only case

* fix(review,ship): plan checks publish a checkpoint before each probe; only the smoke expiry stop is skipped

* fix(qa): carry #2999's checkpoint receipt link, report-template line and full-revision placeholder (identical hunks)

* test(qa-callers): disable git auto maintenance in the caller fixture

Git 2.47+ runs auto maintenance detached after commit; on the CI runner's git
2.55 it rewrote .git/objects fan-out directories while the write observer was
running, which surfaced as unauthorized mutations. Same gc.auto=0 /
maintenance.auto=false guard the shared-libs fixture already uses.

* test(plan-mode-no-op): require prose evidence for the prose-fallback members so a spinner-frame judge verdict cannot end the run as asked

* test(ship-docsync): carry #2999's seeded-attempt docsync harness (identical files)

The doc-sync fault cases replayed attempt 1 before reaching their gate and ran
out of their 285s budget. The fixture now seeds attempt 1 and the parent starts
at the gate under test. Taken byte-identical from origin/capy/audit-fix-wave
(fb526898, e6ac813d, 6ce10ff7, d0c53577, 77cce3be). Local: stale-before,
recovery and late-result 6/6 PASS (97-164s); the whole file 12/12 PASS.

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

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

Absorbed from PR #2615 with authorship preserved; the PR-thread liveness screenshot (docs/images/gstack-pr-liveness-2255.png) is dropped — referenced by nothing in the tree.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Absorbed from PR #2641 with authorship preserved.

Fixes #2635

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

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

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

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

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

Refs #2365

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

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

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

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

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

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

Fixes #2361

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

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

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

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

Fixes #2156

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

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

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

Fixes #2353

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

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

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

Fixes #2656

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

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

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

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

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

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

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

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

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

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

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

* chore: bump version and changelog (v1.69.0.0)

Garry TanandClaude Opus 4.7 e362b0ae2f v1.37.0.0 feat: split-engine gbrain (remote MCP brain + local PGLite for code) (#1500)
* feat(gbrain): add lib/gbrain-local-status classifier with 5-state engine status + 60s cache

Foundation for split-engine gbrain: shared classifier used by both
bin/gstack-gbrain-detect (preamble probe) and bin/gstack-gbrain-sync.ts
(orchestrator SKIP-when-not-ok). Single source of truth.

Probes via `gbrain sources list --json` and classifies stderr against the
same patterns lib/gbrain-sources.ts:66-67 already uses ("Cannot connect to
database", "config.json"). Returns one of: ok, no-cli, missing-config,
broken-config, broken-db. Defensive default: unrecognized failures
classify as broken-config so the raw stderr can be surfaced upstream.

Cache at ~/.gstack/.gbrain-local-status-cache.json keyed on
{home, path_hash, gbrain_bin_path, gbrain_version, config_mtime, config_size}
with 60s TTL. Cache invalidates on any invariant change. --no-cache option
busts the cache for callers that just mutated state (/setup-gbrain,
/sync-gbrain after init/migration).

* refactor(gbrain): rewrite gstack-gbrain-detect bash→TS + add gbrain_local_status field

Replaces the bash detect helper with a bun shebang script sharing the
gbrain_local_status classifier from lib/gbrain-local-status.ts with the
sync orchestrator. Single source of truth for engine-status classification
between preamble-probe and orchestrator-skip paths.

Filename stays gstack-gbrain-detect (no .ts extension) so existing skill
preamble callers shell out unchanged. Shebang `#!/usr/bin/env -S bun run`
resolves bun at runtime.

Output is key/type backward-compatible with the bash version per plan
codex #5: the 9 pre-existing keys (gbrain_on_path, gbrain_version,
gbrain_config_exists, gbrain_engine, gbrain_doctor_ok, gbrain_mcp_mode,
gstack_brain_sync_mode, gstack_brain_git, gstack_artifacts_remote) stay
identical in name + type + value semantics. One new key added:
gbrain_local_status (5-state string enum).

Updates the existing schema regression at test/gstack-gbrain-detect-mcp-mode.test.ts
to include the new key. Adds test/gbrain-detect-shape.test.ts asserting
the regression contract for future changes.

* feat(gbrain): orchestrator SKIP when local engine not ok + remote-http transcripts via artifacts pipeline

Two changes in the sync orchestrator, both per plan D11/D12:

1. bin/gstack-gbrain-sync.ts: runCodeImport + runMemoryIngest call
   localEngineStatus() (shared classifier from lib/gbrain-local-status.ts).
   When status is not 'ok', return a SKIP stage result with a clear reason
   instead of crashing with "source registration failed: gbrain not
   configured". Brain-sync stage runs regardless — it doesn't depend on
   local engine. dry-run preview path is gated above the check so it
   continues to show would-do steps even when the engine is broken.

2. bin/gstack-memory-ingest.ts: when gbrain MCP is registered as
   remote-http (Path 4), persist staged transcripts to
   ~/.gstack/transcripts/run-<pid>-<ts>/ instead of the ephemeral
   ~/.gstack/.staging-ingest-<pid>-<ts>/ tmp dir, and SKIP the local
   `gbrain import` call entirely. The artifacts pipeline (gstack-brain-sync
   push to git, brain admin pulls and indexes) handles routing to the
   remote brain. Local PGLite (when present via Step 4.5) stays code-only.

State recording still happens — prepared pages get their mtime+sha256
stamped under remote-http mode so the next /sync-gbrain doesn't
re-stage them. Cleanup is skipped intentionally so the persisted dir
survives until gstack-brain-sync moves it.

Adds test/gbrain-sync-skip.test.ts covering 5 SKIP scenarios (broken-db,
broken-config, no-cli, missing-config, ok pass-through). All 25
sync-related unit tests pass.

* feat(gbrain): v1.34.0.0 migration notice + transcripts allowlist for artifacts pipeline

Per plan D5 + D11. Two pieces of the split-engine rollout:

1. gstack-upgrade/migrations/v1.34.0.0.sh — prints a one-time
   discoverability notice for existing Path 4 (remote-http MCP) users
   whose machine has no local engine yet. Tells them about /setup-gbrain
   Step 4.5 (the new local-PGLite opt-in). Silent for everyone else.
   User can suppress permanently via `gstack-config set
   local_code_index_offered true`. Touchfile at
   ~/.gstack/.migrations/v1.34.0.0.done makes it idempotent.

2. bin/gstack-artifacts-init — adds `transcripts/run-*/*.md` and
   `transcripts/run-*/**/*.md` to the managed allowlist so the
   gstack-memory-ingest persistent staging dir (used in remote-http
   mode per D11) gets pushed to the artifacts repo. Brain admin's
   pull job then indexes transcripts into the remote brain.
   Privacy class: behavioral (matches transcript content).

Adds test/gstack-upgrade-migration-v1_34_0_0.test.ts with 5 cases:
state match, no-MCP, local-config-present, opt-out, and idempotency.
All 5 pass.

* feat(gbrain): /setup-gbrain Step 1.5/4.5 + /sync-gbrain Step 1.5 templates

Per plan D4, D10, D11, D12. Wires the skill prose to the new
split-engine flow + classifier introduced in earlier commits.

setup-gbrain/SKILL.md.tmpl:
  - Step 1: detect output description now includes the v1.34.0.0
    gbrain_local_status field (5 values).
  - Step 1.5 (NEW): broken-db / broken-config remediation. AskUserQuestion
    with 4 options — Retry / Switch to PGLite / Switch brain mode / Quit
    (plan D4). Retry is recommended first since broken-db often = transient
    Postgres outage. PGLite is explicitly one-way + destructive (moves
    existing config to ~/.gbrain/config.json.gstack-bak-<ts>); rollback on
    init failure restores the .bak (plan D7).
  - Step 4d → Step 4.5 (NEW): in Path 4, after the verify step, offer
    local PGLite for code search. AskUserQuestion Yes/No (plan D10/D11).
    Yes path runs gstack-gbrain-install + `gbrain init --pglite --json`
    with the same rollback-safe sequence. No path skips Steps 3/4/5/7.5.
  - Step 10 verdict (Path 4): adds "Code search" row reflecting Step 4.5
    choice. Updates "Transcripts" row to describe the new D11 routing
    (artifacts repo → remote brain).

sync-gbrain/SKILL.md.tmpl:
  - Step 1 split-engine prose: corrects the prior misleading claim that
    "memory routes through whatever setup-gbrain configured, including
    remote-MCP" (codex finding #3). Memory stage shells out to local
    `gbrain import` in local-stdio mode; in remote-http mode it persists
    to ~/.gstack/transcripts/ for the artifacts pipeline.
  - Step 1.5 (NEW): local-engine pre-flight. STOP on no-cli, broken-config,
    broken-db. Soft skip (continue with code+memory SKIP) on
    missing-config + remote-http per plan D12. Surfaces actionable user
    remediation message instead of the orchestrator crashing two stages
    with ERR.

Regenerated SKILL.md for all hosts (claude, kiro, opencode, slate,
cursor, openclaw, hermes, gbrain). All 712 skill-validation + gen-skill-docs
tests pass.

* test(gbrain): .bak-rollback contract for Step 1.5 / 4.5 init failure path

Per plan D7 (rollback semantics) and codex #10 (rollback scope). The
/setup-gbrain skill instructs the model to follow a specific shell
sequence when running `gbrain init --pglite` against an existing
config:

  1. mv ~/.gbrain/config.json ~/.gbrain/config.json.gstack-bak-<ts>
  2. gbrain init --pglite --json
  3. on non-zero exit: mv .bak back; surface error

This test verifies that contract using a fake `gbrain` binary that
fails on init. Three cases:

  - FAILURE: gbrain init exits non-zero → broken config restored to
    original path, no leftover .bak.
  - SUCCESS: gbrain init exits 0 → new config in place, .bak survives
    for audit (user reviews + deletes manually).
  - SCOPE: any partial PGLite directory at ~/.gbrain/pglite/ is NOT
    auto-cleaned. We only promise to restore config.json; PGLite
    cleanup is the user's call (codex #10).

If the skill template rewrites this sequence in a future change, this
test should fail until the test's shell is updated too. That's the
point — keep the test and the skill template aligned.

* test(gbrain): periodic E2E for /setup-gbrain Path 4 + Step 4.5 Yes flow

End-to-end coverage of the new opt-in question via runAgentSdkTest.
Stubs the MCP endpoint at /tools/list with a 200 response carrying a
fake gbrain v0.32.3.0 serverInfo, and fakes the gbrain + claude CLIs
so init writes a PGLite config and mcp add succeeds. Asserts the model:

  1. invokes gstack-gbrain-install (Step 4.5 Yes branch)
  2. invokes `gbrain init --pglite --json`
  3. writes a working ~/.gbrain/config.json with engine=pglite
  4. registers the remote MCP via `claude mcp add --transport http`
  5. never leaks the bearer token to CLAUDE.md

Classified as periodic-tier per plan D6 (codex #12 flagged AgentSDK
flakiness; gate-tier coverage of the split-engine behavior lives in the
deterministic unit tests at gbrain-local-status.test.ts and
gbrain-sync-skip.test.ts). Touchfile fires the test when the skill
template, install/verify/init helpers, the local-status classifier, or
the agent-sdk-runner harness changes.

* chore(gbrain): bump migration to v1.35.0.0 after main merge

main shipped v1.34.0.0 (factory-export submodule) + v1.34.1.0 (update-check
hardening) while this branch was in flight. The migration file I named
v1.34.0.0.sh now belongs at v1.35.0.0 — the next minor on top of main,
matching the scale of split-engine work (new lib + orchestrator skip +
template overhaul + transcripts routing).

Renames the migration script and its test file; updates all internal
version references in both files. Behavior unchanged.

* perf(gbrain): memoize gbrain resolution + use --fast doctor in detect

Cuts detect's wall time substantially by sharing fork-exec results
between the helper that walks the JSON output and the localEngineStatus
classifier from lib/gbrain-local-status.ts.

Before: detect made 2x `command -v gbrain` calls (one in detect's
detectGbrain, one in the classifier's resolveGbrainBin) and 2x
`gbrain --version` calls. With memoization keyed on PATH, both
collapse to one fork each (~400ms saved per skill preamble).

Also adds `--fast` to the `gbrain doctor --json` call in detect so a
broken-db config (Garry's repro) doesn't burn a full 5s timeout on the
doctor's DB-connection check. The classifier still probes the DB
directly via `gbrain sources list --json` for engine reachability —
that's `gbrain_local_status`, separate from the coarse
`gbrain_doctor_ok` summary flag.

* test(gbrain): relax E2E assertions to smoke-test contract

Per codex #12 (AgentSDK harness is non-deterministic): the E2E now
asserts the model followed the split-engine path WITHOUT requiring a
specific subcommand sequence. Three assertions:

  1. AskUserQuestion was called (model reached interactive branches)
  2. At least one of {gstack-gbrain-install, `gbrain init --pglite`,
     `claude mcp add`} fired (model followed the skill, not a no-op)
  3. The fake bearer token never leaked to CLAUDE.md (security regression)

Deterministic per-step coverage of the same flow lives in the gate-tier
unit tests (gbrain-local-status, gbrain-sync-skip, init-rollback,
upgrade-migration). The E2E exists to catch the "model can't follow
the skill at all" regression class, not to pin the exact tool sequence.

Test passes in 280s against the live Agent SDK.

* test(version): bump CLI smoke-test timeout to 15s (flaky at 5s under load)

The gstack-next-version integration smoke test spawns a child process
that does git operations + sibling-worktree probing. Wall time hovers
4-5s on M-series Macs; flakes at exactly 5001-5002ms when the test
suite runs under load (bun's parallel scheduling). Bumping per-test
timeout to 15s eliminates the flake without changing test logic.
