Garry Tan 3bef43bc5a v1.55.0.0 fix wave: gbrain data-loss guards + browser crash-loop + 6 more (#1808)
* fix(jsonl-merge): make equal-ts resolution converge across machines

The JSONL append merge driver sorted timestamped entries by (0, ts) with no
further tiebreaker. Equal-ts entries then fell back to stable-sort insertion
order (base, ours, theirs), but git assigns the local side to "ours", so two
machines resolving the same conflict emitted equal-ts lines in opposite order.
The merged files diverged and never converged. gstack-telemetry-log uses
second-granularity timestamps, so same-ts collisions are routine.

Add the line content as the final sort tiebreaker so the order is total and
side-independent. Add a regression test that runs the driver with the two
sides swapped and asserts identical output.

* fix(gen-skill-docs): quote frontmatter descriptions with interior colons (#1778)

Generated SKILL.md frontmatter emitted the catalog-trimmed description: as a
plain YAML scalar. A description with an interior ": " (e.g. "Ship workflow:
detect...") parses as a nested mapping under strict YAML loaders, so Codex/OpenAI
skill loading rejected those skills.

applyCatalogTrim now routes the value through toYamlInlineScalar, which quotes
(via JSON.stringify) only when a plain scalar would be invalid — interior ": ",
inline " #", leading indicator char, or surrounding whitespace. Strings that are
already valid plain scalars pass through unchanged to keep regen diffs small.

The frontmatter test now parses every generated block (Claude + Codex hosts) with
Bun.YAML.parse instead of string-checking that name:/description: substrings exist,
so the regression can't reappear. Runs under `bun test` (already in CI).

* chore(skills): regenerate SKILL.md after frontmatter quoting fix (#1778)

9 catalog-trimmed descriptions whose values contain an interior colon or inline-
comment marker are now quoted. Generated output only; rerun of bun run gen:skill-docs.

* refactor(gbrain-sources): centralize sources-list shape handling in parseSourcesList (#1576)

#1576's crash in sourceLocalPath was already fixed in v1.42.0.0 (dual-shape
handling). But the readers disagreed: sourceLocalPath accepted both the wrapped
{sources:[...]} object (v0.20+) and a bare array, while probeSource and
sourcePageCount accepted only the wrapped shape. Extract one parseSourcesList()
normalizer and route all three through it, so the shape assumption lives in a
single place. This is also the base the #1734 remote_url audit builds on.

parseSourcesList returns [] for null/garbage rather than throwing; callers treat
'no rows' as absent. New test/gbrain-sources-parse.test.ts pins both shapes plus
the garbage paths and confirms config.remote_url survives for the audit.

#1576 is closeable as already-fixed in v1.42.0.0.

* fix(gbrain): spawn gbrain + brain-sync through a shell on Windows (#1731)

On Windows, bun/npm install gbrain as a gbrain.cmd/.ps1 shim and gstack-brain-sync
is a bash shebang script. spawnSync/spawn/execFileSync resolve neither without a
shell, so the child spawn failed ENOENT — on the sync orchestrator this surfaced
as 'brain-sync exited undefined' (#1731).

Add NEEDS_SHELL_ON_WINDOWS (process.platform === 'win32') in gbrain-exec and pass
it as shell: to every gbrain/brain-sync child spawn: spawnGbrain, spawnGbrainAsync,
execGbrainText (gbrain-exec), the two sources-list/remove/add spawns (gbrain-sources),
the version + probe spawns (gbrain-local-status), and the two brain-sync spawns in
the orchestrator. POSIX keeps the cheaper no-shell path.

macOS/Linux CI can't exercise the Windows path, so test/gbrain-spawn-windows-shell.ts
is a static-grep tripwire: it fails CI if a gbrain/brain-sync spawn is added without
the shell flag.

* test(catalog-trim): expect YAML-quoted descriptions with interior colons (#1778)

The quoting fix wraps colon-bearing catalog descriptions in double quotes;
two catalog-trim assertions still pinned the old unquoted form. Tolerate the
optional quotes.

* fix(gbrain-sync): defensive guards against destructive gbrain ops (#1734)

The orchestrator shelled out to gbrain's destructive subcommands as if they were
safe. gbrain can rm-rf a user's working tree during an autopilot race (its own
bug, upstream gbrain #1526); gstack now defends itself. New lib/gbrain-guards.ts
gates the two destructive reach points, all checked immediately before the op:

- Autopilot refuse (multi-signal, affirmative-only): refuse a destructive op when
  a live 'gbrain autopilot' process (primary) or a known autopilot lock file
  (secondary; checked under both GBRAIN_HOME and ~/.gbrain since gbrain #1226
  ignores GBRAIN_HOME) is present. No signal → proceed; inability to introspect
  never bricks a normal sync.
- sources remove: routed through safeSourcesRemove → decideSourceRemove. Fail
  CLOSED — refuse to remove a user-managed source (remote_url set, local_path
  outside gbrain's clones) when gbrain has no --keep-storage to protect the files
  (it doesn't in 0.41.x). Also fail closed when the source list can't be read.
  Path containment uses realpath so a symlink can't smuggle a delete out of clones.
- sync --strategy code: decideCodeSync refuses URL-managed sources (remote_url
  set) unless --allow-reclone is passed, since the walk can auto-reclone (rm-rf).

Capability detection memoizes per process keyed to gbrain's identity (no stale
persistent cache); --keep-storage can't be probed (generic help) so it defaults
unsupported → fail closed. Every guard surfaces a visible reason; autopilot/reclone
refusals fail the code stage (verdict ERR) rather than silently skipping protection.

test/gbrain-guards.test.ts covers all branches hermetically (injected rows + probe
overrides): autopilot signals, fail-closed remove, keep-storage path, reclone gate,
realpath/symlink containment. Supersedes #1736 (which guarded a nonexistent path).

* docs(sync-gbrain): warn against running during autopilot; prefer --path sources (#1734)

Adds a Safety note to the /sync-gbrain guidance (template + regenerated SKILL.md +
this repo's CLAUDE.md): don't run while autopilot is active, and prefer
`gbrain sources add --path` over URL-managed sources, which can auto-reclone.

* fix(memory-ingest): configurable import timeout + resume-on-timeout messaging (#1611)

The gbrain import (the long pole on big brains) had a hardcoded 30-min timeout,
so large memory corpora got SIGTERM'd mid-import on /sync-gbrain --full. Make it
configurable via GSTACK_INGEST_TIMEOUT_MS (default 30 min, validated 1min–24h).

gstack can't drive gbrain's internal resume, but the existing SIGTERM forwarder
already preserves gbrain's import-checkpoint.json, so the next run resumes. On a
timeout we now say so explicitly ('checkpoint preserved — re-run /sync-gbrain to
resume, raise GSTACK_INGEST_TIMEOUT_MS for big brains') instead of surfacing a
bare 'exited null'. True gstack-driven ingest-resume is deferred to gbrain
(.context/gbrain-asks.md).

Also guards the module's main() behind import.meta.main so resolveImportTimeoutMs
is unit-testable; the orchestrator runs it as a subprocess where main still fires.
New test/memory-ingest-timeout.test.ts pins default/override/invalid resolution.

* fix(browse): stop the headed daemon crash-loop + silent headless downgrade (#1781)

A headed session against a beacon-heavy page (analytics/extension load) could tip
the single-threaded daemon into a self-inflicted crash-loop: a brief HTTP stall
was read as a crash, the restart didn't clear the dead Chromium's SingletonLock,
the relaunch failed, and the session silently came back headless. Four fixes:

1. Busy-vs-dead (sendCommand): on a connection error, if the process is alive give
   /health a bounded probe (3x/250ms) and just retry the command — never kill+restart
   a live-but-busy server. A 30s timeout now reports 'busy, not restarting' when the
   process is alive instead of exiting into a kill cycle.
2. Profile-lock cleanup on (re)start: startServer reaps the orphaned Chromium holding
   the SingletonLock and clears Singleton{Lock,Socket,Cookie} before relaunch, so the
   auto-restart path gets the same clean profile the manual connect preamble did.
3. Headed persistence: the restart env reapplies BROWSE_HEADED from this invocation OR
   the persisted server state (mode==='headed'), so a restart from a plain command
   never downgrades a headed window to invisible headless. Extracted to buildRestartEnv.
4. Force-clean disconnect reaps the Chromium child tree (via the SingletonLock PID) so
   the next connect starts clean instead of fighting an orphan.

Plus macOS window surfacing: connect + focus raise 'Google Chrome for Testing' to the
active Space (best-effort osascript) with a Mission Control hint — the first thing
users read as 'I can't see the browser'.

Shared lock helpers (chromiumProfileDir / cleanChromiumProfileLocks / killOrphanChromium)
dedupe the connect, disconnect, and restart paths. browse/test/restart-env.test.ts pins
the headed-persistence decision; the full crash-loop repro is an E2E (periodic).

* feat(gbrain-install): remove the v0.18.2 pin, install latest + version floor + doctor self-test (#1744)

The installer pinned gbrain at v0.18.2 while gbrain shipped v0.41.x — ~23 versions
behind. Remove the hard pin: a fresh clone now stays on the latest default-branch
HEAD. --pinned-commit <sha> still pins for reproducibility.

Unpinning removes the version gate the pin provided, so add two install-time gates
that fail closed (exit 3, matching the existing PATH-shadow/version-mismatch posture):
- MIN_GBRAIN_VERSION floor (0.20.0, the sources-list/federated surface gstack needs):
  refuse an install below it.
- gbrain doctor --fast self-test when a brain config already exists (re-install /
  detected clone): refuse to leave a broken gbrain in place. Pre-init installs skip
  it; the full /sync-gbrain --dry-run self-test runs from /setup-gbrain after init.

Docs updated (USING_GBRAIN_WITH_GSTACK.md no longer says 'edit PINNED_COMMIT').
Detect-install tests bump the success-path fixtures above the floor and add a
below-floor exit-3 test. The gbrain-side asks (root #1526 fix, --keep-storage,
remove-lease, capability command, ingest-resume, integration CI) are written to
.context/gbrain-asks.md for filing against garrytan/gbrain.

* test(#1778): update claude-ship golden + catalog-mode assertions for quoted descriptions

ship's catalog description ('Ship workflow: detect...') has an interior colon, so
the #1778 fix now YAML-quotes it. Refresh the claude-ship golden baseline to the
quoted output and make the catalog-mode-full trim/restore assertions quote-tolerant.
codex/factory ship goldens are unaffected (they use block-scalar descriptions).

* fix(gen-skill-docs): use function replacer so a $ in a description can't corrupt frontmatter (#1778)

String.prototype.replace treats $&/$1/$` in the replacement as patterns. A future
skill description containing $ (e.g. referencing $B/$D) would silently corrupt the
generated frontmatter. Use a function replacer. Behavior-preserving for all current
descriptions (regen produces no diff).

USING_GBRAIN_WITH_GSTACK.md: note GSTACK_INGEST_TIMEOUT_MS (default 30 min,

timeout. Fills the reference gap left by the configurable-import-timeout fix
(#1611) shipped in v1.55.0.0.

Garry Tan 2014557e7f v1.12.0.0 feat: /setup-gbrain — coding-agent onboarding for gbrain (#1183)
* 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
writes via tmpfile + rename. Policy file mode 0600. Corrupt files
quarantine to .corrupt-<ts> and start fresh.

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

* test(setup-gbrain): unit tests for gstack-gbrain-repo-policy

24 tests covering normalize (ssh/https/shorthand/uppercase collapse to
one key), set/get round-trip, all three D3 tiers accepted, invalid
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.

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

* 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.

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

* 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.

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

* 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
failures noted as P0 in TODOS.md.

* 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.
