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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* test: review-army + adversarial test hardening

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

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

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

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

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

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

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

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

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

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

* feat(setup-gbrain): add gstack-gbrain-repo-policy bin helper

Per-remote trust-tier store for the forthcoming /setup-gbrain skill.
Tiers are the D3 triad (read-write / read-only / deny), keyed by a
normalized remote URL so ssh-shorthand and https variants collapse to
the same entry. The file carries _schema_version: 2 (D2-eng); legacy
`allow` values from pre-D3 experiments auto-migrate to `read-write`
on first read, idempotent, with a one-shot log line.

Pure bash + jq to match the existing gstack-brain-* family. Atomic

quarantine to .corrupt-<ts> and start fresh.

tiers rejected, file mode 0600, _schema_version field written on fresh
files, legacy allow migration (including idempotence and preservation
of non-allow entries), corrupt-JSON quarantine + fresh-file recovery,
list output sorting, and get-without-arg auto-detect against a git
repo with no origin.

All tests green against a per-test tmpdir GSTACK_HOME so nothing
leaks into the real ~/.gstack.

* feat(setup-gbrain): add gstack-gbrain-detect state reporter

Pure-introspection JSON emitter for the /setup-gbrain skill's
start-up branching. Reports: gbrain presence + version on PATH,
~/.gbrain/config.json existence + engine, `gbrain doctor --json`
health (wrapped in timeout 5s to match the /health D6 pattern),
gstack-brain-sync mode via gstack-config, and ~/.gstack/.git
presence for the memory-sync feature.

Never modifies state. Always emits valid JSON even when every check
is false. Handles malformed ~/.gbrain/config.json without crashing
— gbrain_engine is null in that case, not an error.

* feat(setup-gbrain): add gstack-gbrain-install with D5 detect-first + D19 PATH-shadow guard

Clones gbrain at a pinned commit (v0.18.2) and registers it via
`bun link`. Before any clone:

  D5 detect-first — probes ~/git/gbrain, ~/gbrain, and the install
  target for a valid pre-existing clone (package.json with name
  "gbrain" and bin.gbrain set). If one is found, `bun link` runs
  there instead of cloning a second copy. Prevents the day-one
  duplicate-install footgun on the skill author's own machine.

After install:

  D19 PATH-shadow guard — reads the install-dir's package.json
  version, compares to `gbrain --version` on PATH. On mismatch:
  exits 3, prints every gbrain binary on PATH via `type -a`, and
  gives a remediation menu. Setup skills refuse broken environments
  instead of warning and continuing.

Prereq checks (bun, git, https://github.com reachability) fail fast
with install hints. --dry-run and --validate-only flags let the
skill probe the plan without touching state; tests use them to
cover D5 and D19 without exercising real bun link.

Pin is a load-bearing version: setup-gbrain v1 verified against
gbrain v0.18.2. Updating requires re-running Pre-Impl Gate 1 to
verify gbrain's CLI + config shapes haven't drifted.

* test(setup-gbrain): unit tests for gstack-gbrain-detect + install

15 tests covering: detect emits valid JSON when nothing configured,
reports gstack_brain_git on GSTACK_HOME/.git presence, reads
~/.gbrain/config.json engine, tolerates malformed config, detects
a mocked gbrain binary on PATH with version parsing.

For install: D5 detect-first uses ~/git/gbrain fixtures under a
sandboxed HOME, verifies fall-through to fresh clone when no valid
clone exists, rejects invalid package.json shapes. D19 PATH-shadow
validation uses a fake gbrain on a minimal SAFE_PATH to simulate
version mismatch, same-version-pass, v-prefix tolerance, missing
binary on PATH, and missing version field in package.json.

--validate-only mode in the install bin makes the D19 check unit-
testable without running real bun link (which touches ~/.bun/bin).

* feat(setup-gbrain): add gstack-gbrain-lib.sh with read_secret_to_env (D3-eng)

Shared secret-read helper for PAT (D11) and pooler URL paste (D16).
One implementation of the hardest-to-get-right pattern: stty -echo +
SIGINT/TERM/EXIT trap that restores terminal mode, read into a named
env var, optional redacted preview.

Validates the target var name against [A-Z_][A-Z0-9_]* to prevent
bash name-injection via `read -r "$varname"`. When stdin is not a TTY
(CI, piped tests) the stty branches skip cleanly — piped input doesn't
echo anyway. Exports the var after read so subprocesses inherit it;
callers own the `unset` at handoff time.

Sourced, not executed — no +x bit.

* feat(setup-gbrain): add gstack-gbrain-supabase-verify structural URL check

Zero-network validator for Supabase Session Pooler URLs before handing
them to `gbrain init`. Canonical shape verified per gbrain init.ts:266:
  postgresql://postgres.<ref>:<password>@aws-0-<region>.pooler.supabase.com:6543/postgres

Rejects direct-connection URLs (db.*.supabase.co:5432) with a distinct
exit code 3 and clear IPv6-failure remediation — that's the most common
paste mistake users make, so it earns its own UX path rather than a
generic "bad URL" error.

Never echoes the URL (contains a password) in error messages; tests
verify a distinct seed password never appears in stderr on any reject
path. Accepts URL from argv[1] or stdin ("-" or no arg).

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

* test(setup-gbrain): unit tests for supabase-verify + lib.sh secret helper

22 tests. verify: accepts canonical pooler URL (argv + stdin modes),
rejects direct-connection URL with exit 3, rejects wrong scheme, wrong
port, empty password, missing userinfo, plain 'postgres' user (catches
direct-URL paste errors), wrong host, empty URL. Case-insensitive host
match. Explicit negative: error messages never echo the URL password.

lib.sh read_secret_to_env: reads piped stdin into the named env var,
exports to subprocesses, redacted-preview emits masked form on stderr
with the seed password absent, rejects invalid var names (lowercase,
leading digit, hyphens), rejects missing/unknown flags, secret value
never appears on stdout.

* feat(setup-gbrain): add gstack-gbrain-supabase-provision Management API wrapper

Four subcommands: list-orgs, create, wait, pooler-url. Built against
the verified Supabase Management API shape (Pre-Impl Gate 1):

  - POST /v1/projects with {name, db_pass, organization_slug, region}
    — not the original plan's /v1/organizations/{ref}/projects
  - No `plan` field; subscription tier is org-level per the OpenAPI
    description ("Subscription Plan is now set on organization level
    and is ignored in this request")
  - GET /v1/projects/{ref}/config/database/pooler for pooler config
    — not /config/database

Secrets discipline: SUPABASE_ACCESS_TOKEN (PAT) and DB_PASS read from
env only, never from argv (D8 grep test enforces this). `set +x` at
the top as a defensive default so debug tracing never leaks secrets.
Management API hostname hardcoded to SUPABASE_API_BASE env override —
no user-controlled URL portion (SSRF guard).

HTTP error paths: 401/403 → exit 3 (auth), 402 → 4 (quota), 409 → 5
(conflict), 429 + 5xx → exponential-backoff retry up to 3 attempts,
then exit 8. Wait subcommand polls every 5s until ACTIVE_HEALTHY
with a configurable timeout; terminal states (INIT_FAILED, REMOVED,
etc.) exit 7 immediately with a clear message. Timeout emits the
--resume-provision hint so the skill can recover.

Pooler-url constructs the URL locally from db_user/host/port/name +
DB_PASS rather than trusting the API response's connection_string
field, which is templated with [PASSWORD] rather than the real value.
Handles both object and array response shapes, preferring session
pool_mode when Supabase returns multiple pooler configs.

* test(setup-gbrain): unit tests for gstack-gbrain-supabase-provision via mock API

22 tests covering D21 HTTP error suite (401/403/402/409/429/5xx) and
happy paths for all four subcommands. Every test spins up a Bun.serve
mock server bound to SUPABASE_API_BASE so nothing hits the real API.

Uses Bun.spawn (async) rather than spawnSync because spawnSync blocks
the Bun event loop, which prevents Bun.serve mocks from responding —
calls would hit curl's own timeout instead of round-tripping.

Verifies: POST body contains organization_slug (not organization_id)
and no `plan` field, bearer-token auth header, retry-on-429 with
eventual success, exit-8 on persistent 5xx after max retries, wait
succeeds on ACTIVE_HEALTHY, exits 7 on INIT_FAILED, exits 6 with
--resume-provision hint on timeout, pooler-url builds URL locally
from db_user/host/port/name + DB_PASS (not response connection_string
template), handles array pooler responses.

* feat(setup-gbrain): add SKILL.md.tmpl — user-facing skill prompt

Stitches together every slice built so far (repo-policy, detect,
install, lib.sh secret helper, supabase-verify, supabase-provision)
into a single interactive flow. Paths: Supabase existing-URL, Supabase
auto-provision (D7), Supabase manual, PGLite local, switch (PGLite ↔
Supabase via gbrain migrate wrapped in timeout 180s per D9).

Secrets discipline per D8/D10/D11: PAT + DB_PASS + pooler URL all
read via read_secret_to_env from lib.sh and handed to gbrain via
GBRAIN_DATABASE_URL env, never argv. PAT carries the full D11 scope
disclosure before collection and an explicit revocation reminder after
success. D12 SIGINT recovery prints the in-flight ref + resume command.

D18 MCP registration is scoped honestly to Claude Code — skips with
a manual-register hint when `claude` is not on PATH. D6 per-remote
trust-triad question (read-write/read-only/deny/skip-for-now) gates
repo import; the triad values compose with the D2-eng schema-version
policy file so future migrations stay deterministic.

Skill runs concurrent-run-locked via mkdir ~/.gstack/.setup-gbrain.lock.d
(atomic, same pattern as gstack-brain-sync). Telemetry (D4) payload
carries enumerated categorical values only — never URL, PAT, or any
postgresql:// substring.

--repo, --switch, --resume-provision, --cleanup-orphans shortcut modes
documented inline; the skill parses its own invocation args.

* feat(health): integrate gbrain as D6 composite dimension

Adds a GBrain row to the /health dashboard rubric with weight 10%.
Three sub-signals rolled into one 0-10 score: doctor status (0.5),
sync queue depth (0.3), last-push age (0.2). Redistributes when
gbrain_sync_mode is off so the dimension stays fair.

Weights rebalance: typecheck 25→22, lint 20→18, test 30→28,
deadcode 15→13, shell 10→9, gbrain +10 — sums to 100.

gbrain doctor --json wrapped in timeout 5s so a hung gbrain never
stalls the /health dashboard. Dimension is omitted (not red) when
gbrain is not installed — running /health on a non-gbrain machine
shouldn't penalize that choice.

History-JSONL adds a `gbrain` field. Pre-D6 entries read as null for
trend comparison; new tracking starts from first post-D6 run.

* feat(test): add secret-sink-harness for negative-space leak testing (D21 #5)

Runs a subprocess with a seeded secret, captures every channel the
subprocess could leak through, and asserts the seed never appears.
Built per the D1-eng tightened contract: per-run tmp $HOME, four seed
match rules (exact + URL-decoded + first-12-char prefix + base64),
fd-level stdout/stderr capture via Bun.spawn, post-mortem walk of
every file written under $HOME, separate buckets for telemetry JSONL.

Reusable: any future skill that handles secrets can import
runWithSecretSink and run positive/negative controls against its own
bins. The harness itself is ~180 lines of TS with no external deps
beyond Bun + node:fs.

Out of scope for v1 (documented as follow-ups): subprocess env dump
(portable /proc reading), the user's real shell history (bins don't
modify it).

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

* test: secret-sink harness positive controls + real-bin negative controls

11 tests. Positive controls deliberately leak a seed in every covered
channel (stdout, stderr, a file under $HOME, the telemetry JSONL path,
base64-encoded, first-12-char prefix) and assert the harness catches
each one. Without these, a harness that silently under-reports would
look identical to a harness that works.

Negative controls run real setup-gbrain bins with distinctive seeds:
  - supabase-verify rejects a mysql:// URL and a direct-connection URL,
    password never appears in any captured channel
  - lib.sh read_secret_to_env reads piped stdin, emits only the length,
    seed value stays invisible
  - supabase-provision on an auth-failure path fails fast without
    leaking the PAT to any channel

Covers D21 #5 leak harness + uses it to validate D3-eng, D10, D11
discipline end-to-end on the already-shipped bins.

* feat(setup-gbrain): add list-orphans + delete-project subcommands (D20)

Powers /setup-gbrain --cleanup-orphans. list-orphans filters the
authenticated user's Supabase projects by name prefix (default
"gbrain") and excludes the project the local ~/.gbrain/config.json
currently points at, so only unclaimed gbrain-shaped projects come
back. Active-ref detection parses the pooler URL's user portion
(postgres.<ref>:<pw>@...).

delete-project is a thin DELETE /v1/projects/{ref} wrapper with no
confirmation of its own — the skill's UI layer owns the per-project
confirm AskUserQuestion loop. Keeps responsibilities clean: the bin
manages HTTP; the skill manages user intent.

Both subcommands reuse the existing api_call retry+backoff and the
same PAT discipline (env only, never argv).

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

* test(setup-gbrain): list-orphans active-ref filtering + delete-project 404

6 new tests bringing the supabase-provision suite to 28:

list-orphans:
  - Filters to gbrain-prefixed projects, excludes the active-ref derived
    from ~/.gbrain/config.json's pooler URL
  - Treats all gbrain-prefixed projects as orphans when no config exists
    (first run on a new machine)
  - Respects custom --name-prefix for users who named their brain
    something else

delete-project:
  - Happy path sends DELETE /v1/projects/<ref> and returns {deleted_ref}
  - 404 surfaces cleanly (exit 2, "404" in stderr)
  - Missing <ref> positional rejected with exit 2

Uses per-test tmpdir HOME with a stubbed ~/.gbrain/config.json so
active-ref extraction runs against deterministic fixtures.

* chore: regenerate setup-gbrain SKILL.md after main merge

* chore: bump version and changelog (v1.12.0.0)

Ships /setup-gbrain and its supporting infrastructure end-to-end:
per-remote trust policy, installer with PATH-shadow guard, shared
secret-read helper, structural URL verifier, Supabase Management
API wrapper, /health GBrain dimension, secret-sink test harness.

100 new tests across 5 suites, all green. Three pre-existing test

* docs: add USING_GBRAIN_WITH_GSTACK.md + update README for /setup-gbrain

README changes:
- Rewrote the "Cross-machine memory with GBrain sync" section into
  "GBrain — persistent knowledge for your coding agent." Covers the
  three /setup-gbrain paths (Supabase existing URL, auto-provision,
  PGLite local), MCP registration, per-remote trust triad, and the
  (still-separate) memory sync feature.
- Added /setup-gbrain row to the skills table pointing at the full guide.
- Added /setup-gbrain to both skill-list install snippets.
- Added USING_GBRAIN_WITH_GSTACK.md to the Docs table.

New doc (USING_GBRAIN_WITH_GSTACK.md):
- All three setup paths with trust-surface caveats
- MCP registration details (and honest Claude-Code-v1 scoping)
- Per-remote trust triad semantics + how to change a policy
- Switching engines (PGLite ↔ Supabase) via --switch
- GStack memory sync + its relationship to the gbrain knowledge base
- /setup-gbrain --cleanup-orphans for orphan Supabase projects
- Full command + flag reference, every bin helper, every env var
- Security model: what's enforced in code, what's enforced by the leak
  harness, and the honest limits of v1
- Troubleshooting: PATH shadowing, direct-connection URL reject,
  auto-provision timeout, stale lock, policy file hand-edits,
  migrate hang
- Why-this-design section explaining the non-obvious choices

* fix(brain-sync): secret scanner now catches Bearer-prefixed auth tokens in JSON

The bearer-token-json regex value charset was [A-Za-z0-9_./+=-]{16,},
which does NOT permit spaces. Real HTTP auth headers embed the scheme
name with a literal space — "Bearer <token>" — so the value portion
actually starts with "Bearer " and the existing regex couldn't match.
Result: any JSON blob containing "authorization":"Bearer ..." would
slip past the scanner and sync to the user's private brain repo with
the bearer token inline.

Added optional (Bearer |Basic |Token )? prefix in front of the value
charset. Now matches the common auth-scheme forms without broadening
the matcher to tolerate arbitrary whitespace (which would false-positive
on lots of benign JSON).

Verified against 5 positive cases (bearer-in-json, clean bearer, apikey
no-prefix, token with Bearer, password no-prefix) + 3 negative cases
(too-short tokens, non-secret field names like username, random JSON).

This closes the P0 security regression first noticed during v1.12.0.0
/ship. brain-sync.test.ts now passes all 7 secret-scan fixtures.

* test: mock-gh integration tests for gstack-brain-init auto-create path

8 tests covering the gh-repo-create happy path that had zero coverage
before. Existing brain-sync.test.ts always passes --remote <bare-url>
to bypass gh entirely, so the interactive default ("press Enter, we'll
run gh repo create for you") was shipping on trust.

Test strategy: write a bash stub for gh that records every call into
a file, then run gstack-brain-init with that stub on PATH. Assertions
verify: gh auth status is checked, gh repo create fires with the
computed gstack-brain-<user> default name + --private + --source
flags, fall-through to gh repo view when create reports already-exists,
user-provided URL bypasses gh entirely, gh-not-on-path and gh-not-authed
branches both prompt for URL, --remote flag short-circuits all gh
calls, conflicting-remote re-runs exit 1 with a clear message.

No real GitHub, no live auth. Gate tier — runs on every commit.

* test(e2e): privacy-gate AskUserQuestion fires from preamble (periodic tier)

Two periodic-tier E2E tests exercising the preamble's privacy gate
end-to-end via the Agent SDK + canUseTool. Previously uncovered:

- Positive: stages a fake gbrain on PATH + gbrain_sync_mode_prompted=false
  in config, runs a real skill, intercepts tool-use. Asserts the
  preamble fires a 3-option AskUserQuestion matching the canonical
  prose ("publish session memory" / "artifact" / "decline") and does
  NOT fire a second time in the same run (idempotency within session).

- Negative: same staging but prompted=true. Asserts the gate stays
  silent even with gbrain detected on the host.

Registered in test/helpers/touchfiles.ts as `brain-privacy-gate`
(periodic) with dependency tracking on generate-brain-sync-block.ts,
the three gstack-brain-* bins, gstack-config, and the Agent SDK runner.
Diff-based selection re-runs the E2E when any of those change.

Cost: ~$0.30-$0.50 per run. Only fires under EVALS=1 EVALS_TIER=periodic;
gate tier stays free.

* docs: update TODOS for bearer-json fix + new brain-sync test coverage

Moves the bearer-json secret-scan regression from the P0 "pre-existing
failures" block into the Completed section with full context on the
fix, the mock-gh tests, the E2E privacy-gate tests, and the touchfile
registration. Remaining P0s are the GSTACK_HOME config-isolation bug
and the stale Opus 4.7 overlay pacing assertion, both unrelated.

* fix(test): E2E privacy gate — ambient env + skill-file prompt

Two fixes to get the E2E actually running end-to-end (first attempt
failed at the SDK auth step, second at the assertion step):

1. Don't pass an explicit `env:` object to runAgentSdkTest. The SDK's
   auth pipeline misses ANTHROPIC_API_KEY when env is supplied as an
   object (verified against the plan-mode-no-op test, which passes no
   env and auths cleanly). Mutate process.env before the call instead,
   and restore the originals in finally so other tests don't inherit
   the ambient mutation.

2. The "Run /learn with no arguments" user prompt was too narrow — the
   model reduced it to a direct action and skipped the preamble
   privacy-gate directives entirely, so zero AskUserQuestions fired.
   Mirror the plan-mode-no-op pattern: point the model at the skill
   file on disk and ask it to follow every preamble directive. Bumped
   maxTurns from 6 to 10 to give the preamble room to execute.

Verified both tests pass under `EVALS=1 EVALS_TIER=periodic bun test
test/skill-e2e-brain-privacy-gate.test.ts` against a real ANTHROPIC_API_KEY.
Cost per run: ~$0.30-$0.50 per test.

* docs(CLAUDE.md): source ANTHROPIC/OPENAI keys from ~/.zshrc for paid evals

Conductor workspaces don't inherit the interactive shell env, so
both API keys are absent from the default process env even though
they're set in ~/.zshrc. Documents the source-from-zshrc pattern
(grep + eval, never echo the value) plus the Agent SDK gotcha: do
NOT pass env as an object to runAgentSdkTest — mutate process.env
ambiently and restore in finally.

Discovered this during the brain-privacy-gate E2E. First run failed
at SDK auth with 401; second failed because explicit env handoff
bypassed the SDK's own auth routing. Fix pattern now codified so
the next paid-eval session in a Conductor workspace doesn't hit the
same two dead ends.
