Garry Tan 675717e320 v1.17.0.0: setup-gbrain wireup ships the gbrain federation surface (#1234) 
* feat: gstack-gbrain-source-wireup helper + 13 unit tests

The new bin/gstack-gbrain-source-wireup is the single helper that registers
the gstack brain repo as a gbrain federated source via `git worktree`, runs
incremental sync, and supports --uninstall + --probe + --strict modes.

Replaces the dead `consumers.json + ingest_url + /ingest-repo` HTTP wireup
introduced in v1.12.0.0 — that endpoint never shipped on the gbrain side.
The federation surface (`gbrain sources` / `gbrain sync`) shipped in gbrain
v0.18.0; this helper adapts to its actual semantics (no `sources update`, so
path drift recovery is `remove + re-add`; no `--install-cron` either, so
freshness rides on the existing skill-end push hook).

Source-id derivation is multi-fallback: ~/.gstack/.git origin URL →
~/.gstack-brain-remote.txt → --source-id flag. This makes `--uninstall`
work even after `~/.gstack/.git` is destroyed by the parent uninstall script.

Worktree is `--detach`ed at $GSTACK_HOME's HEAD because main is already
checked out there; advance is a re-checkout of the parent's current HEAD,
not a `git pull`. Divergence recovery removes + re-adds the worktree.

Test suite covers 13 cases: fresh-state registration, idempotent re-runs,
drift recovery, --strict failure modes, source-id fallback chain, --probe
non-mutation, sync errors, and --uninstall. Fake gbrain on $PATH, real git
ops at GSTACK_HOME tmp dir.

* feat: wire setup-gbrain + brain-restore + brain-uninstall to use the helper

setup-gbrain Step 7 now invokes gstack-gbrain-source-wireup --strict after
gstack-brain-init + gbrain_sync_mode is set. Strict mode means the user sees
the failure rather than silently ending up with an unwired brain.

bin/gstack-brain-init drops 60 lines of dead code: the HTTP POST to
${GBRAIN_URL}/ingest-repo, the GBRAIN_URL_VAL/GBRAIN_TOKEN_VAL probes, the
consumers.json writer, and the chore commit step. CONSUMERS_FILE variable
declaration removed. The closing message no longer points at the dead
gstack-brain-consumer add path.

bin/gstack-brain-restore drops the 18-line consumers.json token-rehydration
block (was a no-op for the only consumer that ever existed). Adds a
best-effort wireup invocation after the brain-repo clone so 2nd-Mac restore
gets gbrain federation automatically. Failure prints a stderr WARNING but
does not abort the restore — restore's primary job is the git clone.

bin/gstack-brain-uninstall calls the helper's --uninstall mode (which
removes the gbrain source registration, the git worktree, and the
future-launchd-plist stub) before the existing legacy consumers.json
removal. Ordering is fragile-by-design: helper derives source-id via
multi-fallback so it works even after .git is destroyed.

bin/gstack-brain-consumer gets a DEPRECATED header note. Stays in the tree
for one cycle of grace; removal in v1.13.0.0.

setup-gbrain/SKILL.md is regenerated from the .tmpl via gen:skill-docs.

* feat: v1.12.3.0 migration — wire existing brain-sync repos into gbrain

Idempotent migration script. For users who already opted into brain-sync
before this release (gbrain_sync_mode != off, ~/.gstack/.git exists), runs
the new gstack-gbrain-source-wireup helper so their existing brain repo
becomes searchable via gbrain immediately on /gstack-upgrade.

Skip conditions (each ends with exit 0):
  - HOME unset or empty (defensive)
  - gbrain_sync_mode = off or empty (user opted out)
  - no ~/.gstack/.git (brain-init never ran)
  - helper missing on disk (broken install)

No --strict on the helper invocation: missing or old gbrain is a benign
skip during a batch upgrade rather than a blocker.

* v1.12.3.0: setup-gbrain wireup ships the gbrain federation surface

Bumps VERSION 1.12.2.0 → 1.12.3.0 with a release-notes-format entry in
CHANGELOG.md. After upgrade, the placeholder consumers.json wireup is gone,
gbrain sources + sync + skill-end hook is the new path, your gstack memory
is actually searchable in gbrain.

The CHANGELOG entry follows the release-summary format from CLAUDE.md:
two-line bold headline, lead paragraph naming what shipped, "verify after
upgrade" command block readers can run on their own brain to see the
delta, then the standard Itemized changes / What this means / For
contributors sections.

Three pre-existing test failures on this branch are flagged in the
contributor section: the GSTACK_HOME isolation test (reads Garry's actual
~/.gstack/config.yaml), the 2MB tracked-binary test (security-bench
fixtures > 2MB), and the Opus 4.7 pacing-directive test (overlay text
drifted). All three were verified to fail on the base branch too — out
of scope for this PR, follow-up needed.

* feat: helper locks GBRAIN_DATABASE_URL at startup, defends against config rewrites

The wireup helper previously read ~/.gbrain/config.json on every gbrain
subprocess invocation. On Garry's Mac, multiple concurrent test runs and
agent integrations were rewriting that file mid-sync, redirecting the
wireup at the wrong brain partway through a 4-min initial import.

This commit adds a `--database-url <url>` flag to the helper and locks
the URL at startup. Precedence:
  1. --database-url flag                       (explicit caller intent)
  2. GBRAIN_DATABASE_URL / DATABASE_URL env    (CI / manual override)
  3. read once from ~/.gbrain/config.json      (default)

Whichever wins gets exported as GBRAIN_DATABASE_URL for every child
`gbrain` invocation. Per gbrain's loadConfig at src/core/config.ts:53,
env-var URLs override the file URL — so a process that flips config.json
between two of our gbrain calls can't redirect us. Defense-in-depth:
once the URL is locked, the wireup completes against the original brain
even under hostile filesystem conditions.

setup-gbrain/SKILL.md.tmpl Step 7 now reads the URL out of config.json
once (via python3 inline) and passes it explicitly with --database-url,
so even the very first wireup call is decoupled from config.json mutability.

Three new test cases cover the lock behavior:
  - --database-url flag is exported to child gbrain calls
  - falls back to ~/.gbrain/config.json when no flag and no env
  - flag overrides env GBRAIN_DATABASE_URL and config.json values

The fake gbrain in the test suite now records GBRAIN_DATABASE_URL alongside
each call so tests can assert the helper exported the locked URL.

Total test count: 13 → 16 passing.

* chore: bump v1.12.3.0 references to v1.15.1.0 to match merged-with-main release

Internal-only renames after merging origin/main bumped this branch's release
target from v1.12.3.0 → v1.15.1.0:

- gstack-upgrade/migrations/v1.12.3.0.sh → v1.15.1.0.sh (rename + log-prefix
  bump from "[v1.12.3.0]" to "[v1.15.1.0]")
- bin/gstack-brain-consumer header: "DEPRECATED in v1.12.3.0" → "DEPRECATED in
  v1.15.1.0"; removal target bumped from v1.13.0.0 → v1.16.0.0 (next minor
  after v1.15.1.0).
- bin/gstack-brain-uninstall: "no longer written ... since v1.12.3.0" →
  "since v1.15.1.0".

No behavior change. Test suite still 16/16 passing.

* test: 10 new cases close coverage gaps (helper defensive paths + migration)

/ship Step 7 coverage audit reported 48% (22/46 branches). Added 10 cases
covering the highest-impact gaps:

Helper (test/gstack-gbrain-source-wireup.test.ts, +3 cases → 19 total):
- --uninstall when gbrain is missing: best-effort exit 0, worktree still cleaned
- --no-pull skips HEAD advance on existing worktree (was untested)
- Stray non-git directory at worktree path is cleaned up + worktree created

Migration (test/gstack-upgrade-migration-v1_15_1_0.test.ts, NEW, 7 cases):
- HOME unset → defensive exit 0
- gbrain_sync_mode=off → exit 0 silently
- gbrain_sync_mode unset → exit 0 silently
- no ~/.gstack/.git → exit 0 silently
- helper missing on PATH → warning + exit 0
- happy path → invokes helper without --strict
- helper exits non-zero → migration prints retry hint, still exits 0 (non-blocking)

Also syncs package.json version from 1.15.0.0 → 1.15.1.0 to match VERSION
file (DRIFT_STALE_PKG repair from /ship Step 12 idempotency check; was a
manual-edit-bypass artifact from the merge step).

Coverage estimate: 48% → ~75%. Mainline + migration script + key defensive
paths all exercised. 26 tests total covering the new code surface.

* fix: pre-landing review auto-fixes (5 correctness + observability)

/ship Step 9 review surfaced 9 INFORMATIONAL findings on the new helper +
migration. Five auto-fixed with no behavior regression (26/26 tests pass):

bin/gstack-gbrain-source-wireup:
- Version compare: put floor "0.18.0" first in `sort -V` stdin so equal-or-
  greater $v always sorts to position 2. Stable across sort implementations.
- _worktree_add_detached: drop `2>/dev/null` on the `worktree add`, surface
  git's stderr through `prefix` so users see WHY adds fail (disk, perms).
- ensure_worktree: same observability fix on the `git checkout --detach` path
  during HEAD-advance, so users see the actual git error before recovery.
- do_probe: replace `[ -d X ] || [ -f X ] && set=present` (precedence trap —
  the `&&` short-circuits when the dir branch fails) with explicit if-block.
- do_probe: capture `check_source_state`'s return code explicitly via
  `set +e; ...; rc=$?; set -e`. `$?` after an `if`/`elif` chain is fragile
  under set -e and may not reach the elif under some shell versions.
- do_wireup: same explicit return-code capture for `ensure_worktree`. The
  prior `ensure_worktree || { if [ $? = 2 ]; ...` pattern relied on `$?`
  reflecting the function's return after `||`, which is implementation-defined.

gstack-upgrade/migrations/v1.15.1.0.sh:
- Trim whitespace from `gstack-config get gbrain_sync_mode` output via
  `tr -d '[:space:]'`. Trailing newlines would mis-classify "off\n" as a
  non-empty non-off mode and incorrectly invoke the helper.

Skipped findings (cosmetic / out of scope):
- `python3 -c` reads `~/.gbrain/config.json` via `expanduser` instead of
  the helper's `$GBRAIN_CONFIG` variable (cosmetic; HONORS HOME override).
- Long sync-failure error message could truncate to last N lines (cosmetic
  log readability).

* fix: adversarial review hardening (rm safety, jq probe, secret redaction, multi-Mac)

/ship Step 11 adversarial review surfaced 7 CRITICAL issues. Five fixed
inline (no behavior regression, 26/26 tests still pass):

bin/gstack-gbrain-source-wireup:

1. **rm -rf path validation** (was: F-c-CRITICAL 9/10).
   Added `safe_rm_worktree` helper that refuses any path not strictly under
   $HOME/, plus dangerous-path allowlist for /, /Users, $HOME root. Replaces
   raw `rm -rf "$WORKTREE"` calls (lines 161, 169 originally). If user sets
   GSTACK_BRAIN_WORKTREE="" or "/", the helper now dies cleanly instead of
   nuking the home dir or root.

2. **jq dependency probe** (was: F-c-CRITICAL 9/10).
   `check_source_state` now hard-fails with a clear message if jq is missing,
   instead of silently returning "absent" → re-add → die-on-duplicate. Plus
   trims whitespace from jq output (`tr -d '[:space:]'`) to defend against
   gbrain emitting `\n` for missing fields. Header comment claimed jq was a
   transitive dep; now we enforce it.

3. **Python heredoc warns on JSON parse failure** (was: F-c-CRITICAL 8/10).
   Previously `except Exception: pass` silently swallowed malformed JSON,
   leaving _locked_url empty and defeating the URL-lock defense. Now writes
   the parse error to a temp file and warns the user that the URL was not
   locked. Also passes the config path via env var (GBRAIN_CONFIG_PATH)
   instead of hardcoded `~/.gbrain/config.json`, respecting any HOME override.

4. **Multi-Mac source-id collision fix** (was: F-c-CRITICAL 9/10).
   When `check_source_state` returns 1 (source exists at different path), the
   helper used to remove + re-add. Two Macs sharing one Supabase brain would
   ping-pong the local_path metadata on every sync. Now: if the existing
   path's basename matches the local worktree's basename (likely another
   machine's local copy of the SAME brain repo), skip re-registration and
   sync against the local worktree. gbrain stores pages by content; metadata
   is informational. No more ping-pong.

5. **Redact DB URL from sync-failure error message** (was: F-c-CRITICAL 7/10).
   `gbrain sync` failures used to echo the full stderr (which can contain
   the postgres connection string with password) into the user's terminal
   and any log redirect. Now we sed-replace any `postgres://...` with
   `postgres://***REDACTED***` before the die() call, and only show the
   last 10 lines.

Bonus minor fix: `die()` now uses `$1` instead of `$*` for the warn
message, so the exit-code arg ($2) doesn't get appended to the warning text.

Acknowledged-but-deferred:
- GBRAIN_DATABASE_URL env exposure on Linux via /proc/$PID/environ. This is
  a Linux-only concern; gstack is Mac-targeted today and macOS restricts
  process env reads. Document as a follow-up if Linux support lands.
- gbrain version parser brittleness if gbrain switches to "v0.18.0" prefix.
  Defensive only; current gbrain output matches `gbrain X.Y.Z` exactly.
- bash 3.2 PIPESTATUS reliability. Tests pass on the host bash version (3.2+
  via macOS); modern bash 5.x is widely available.

* docs: sync gbrain-source-wireup helper into USING_GBRAIN + gbrain-sync

USING_GBRAIN_WITH_GSTACK.md: add gstack-gbrain-source-wireup row to the bin
helpers table — describes federation registration via `gbrain sources add` +
worktree, lists flags, calls out it replaces the dead consumers.json/ingest-repo
HTTP wireup.

docs/gbrain-sync.md: replace the `gstack-brain-reader add --ingest-url` step
in gstack-brain-init's flow (which targeted the never-shipped /ingest-repo
endpoint) with the real flow — federate via gbrain sources + worktree, point
to bin/gstack-gbrain-source-wireup.

* v1.16.1.0: rebump after queue-collision (PR #1233 took v1.16.0.0)

CI's "Check VERSION is not stale vs queue" job (job 73105686380) failed
with: "VERSION drift: PR #1234 claims v1.15.1.0 but the queue has moved —
next free slot is v1.16.1.0." PR #1233 (garrytan/browserharness) entered
the queue claiming v1.16.0.0 between when this branch's prior /ship ran
and when CI evaluated, so v1.15.1.0 is stale. Rebumping on top.

Files updated:
- VERSION                                                     1.15.1.0 → 1.16.1.0
- package.json                                                1.15.1.0 → 1.16.1.0
- CHANGELOG.md heading + Before/After columns                 1.15.1.0 → 1.16.1.0
- CHANGELOG removal target (consumers.json + config keys)     1.16.0.0 → 1.17.0.0
- gstack-upgrade/migrations/v1.15.1.0.sh                      → renamed v1.16.1.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.15.1.0/1.16.0.0 → 1.16.1.0/1.17.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.15.1.0 → 1.16.1.0
- test/gstack-upgrade-migration-v1_15_1_0.test.ts             → renamed v1_16_1_0.test.ts

No behavior change. 26/26 wireup + migration tests still pass on the rename.
Full bun test suite: exit 0, 0 failures.

* v1.17.0.0: rebump again — bump-detection now classifies branch as MINOR

CI's version-stale check (job 73106360896) failed: PR #1234 claims v1.16.1.0
but the queue moved to v1.17.0.0. Root cause: bumping 1.15.1.0 → 1.16.1.0
to dodge the prior collision turned the branch's diff classification from
PATCH (1.15.0 → 1.15.1) into MINOR (1.15.0 → 1.16.x). detect-bump.ts now
sees MINOR, gstack-next-version walks the MINOR lane past #1233's
v1.16.0.0 claim, and the next free slot is v1.17.0.0.

Honestly accurate per CLAUDE.md scale-aware bumps: this branch IS a
MINOR ("substantial new capability shipped — skill, harness, command,
big refactor"). The new helper + migration + integration totals ~1200
lines added across 11 files with 26 new tests. PATCH was always the
wrong honest classification; the queue collision forced the right
answer.

Files updated:
- VERSION                                                     1.16.1.0 → 1.17.0.0
- package.json                                                1.16.1.0 → 1.17.0.0
- CHANGELOG.md heading + After column                         1.16.1.0 → 1.17.0.0
- CHANGELOG removal targets                                   1.17.0.0 → 1.18.0.0
- gstack-upgrade/migrations/v1.16.1.0.sh                      → renamed v1.17.0.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.16.1.0/1.17.0.0 → 1.17.0.0/1.18.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.16.1.0 → 1.17.0.0
- test/gstack-upgrade-migration-v1_16_1_0.test.ts             → renamed v1_17_0_0.test.ts

26/26 tests still pass. No behavior change.

Garry Tan dde55103fc v1.15.0.0 feat: slim preamble + real-PTY plan-mode E2E harness (#1215) 
* chore: add gstack skill routing rules to CLAUDE.md

Per routing-injection preamble — once-per-project addition that lets
agents auto-invoke the right gstack skill instead of answering generically.

* refactor: slim preamble resolvers + sidecar-symlink helper

Compress prose across 18 preamble resolvers — Voice, Writing Style,
AskUserQuestion Format, Completeness Principle, Confusion Protocol,
Context Health, Context Recovery, Continuous Checkpoint, Lake Intro,
Proactive Prompt, Routing Injection, Telemetry Prompt, Upgrade Check,
Vendoring Deprecation, Writing Style Migration, Brain Sync Block,
Completion Status, and Question Tuning. Same semantic contract, ~half
the bytes. Restored "Treat the skill file as executable instructions"
phrase in the plan-mode info section after diagnosing it as load-bearing.
Restored "Effort both-scales" rule in AskUserQuestion format.

Bonus: scripts/skill-check.ts gains isRepoRootSymlink() so dev installs
that mount the repo root at host/skills/gstack as a runtime sidecar
(e.g., codex's .agents/skills/gstack) get skipped instead of double-counted.

opus-4-7 model overlay gets a Fan-Out directive — explicit instruction
to launch parallel reads/checks before synthesis.

Net token impact across all generated SKILL.md files: ~140K tokens
removed across 47 outputs. Plan-* skills retain full preamble surface
(Brain Sync, Context Recovery, Routing Injection) — load-bearing
functionality that early slim attempts incorrectly cut.

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

* chore: regenerate SKILL.md outputs after preamble slim

bun run gen:skill-docs --host all output. Mirrors the resolver changes
in the previous commit. 47 generated SKILL.md files plus 3 ship-skill
golden fixtures.

* feat(test): real-PTY harness for plan-mode E2E tests

Adds test/helpers/claude-pty-runner.ts. Spawns the actual claude binary
via Bun.spawn({terminal:}) (Bun 1.3.10+ has built-in PTY — no node-pty,
no native modules), drives it through stdin/stdout, and parses rendered
terminal frames. Pattern adapted from the cc-pty-import branch's
terminal-agent.ts but stripped of WS/cookie/Origin scaffolding (not
needed for headless tests).

Public API:
- launchClaudePty(opts) — boots claude with --permission-mode plan|null,
  auto-handles the workspace-trust dialog, returns a session handle.
- session.send / sendKey / waitForAny / waitFor / mark / visibleSince /
  visibleText / rawOutput / close
- runPlanSkillObservation({skillName, inPlanMode, timeoutMs}) — high-level
  contract for plan-mode skill tests. Returns { outcome, summary, evidence,
  elapsedMs }. outcome ∈ {asked, plan_ready, silent_write, exited, timeout}.

Replaces the SDK-based runPlanModeSkillTest from plan-mode-helpers.ts
which never worked. Plan mode renders its native "Ready to execute"
confirmation as TTY UI (numbered options with ❯ cursor), not via the
AskUserQuestion tool — so the SDK's canUseTool interceptor never fired
and the assertion always saw zero questions. Real PTY observes the
rendered output directly.

Deletes test/helpers/plan-mode-helpers.ts. No production callers remained.

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

* test: rewrite 5 plan-mode E2E tests on the real-PTY harness

Replaces SDK-based assertions with runPlanSkillObservation contract. Each
test launches real claude --permission-mode plan, invokes the skill, and
asserts the outcome reaches 'asked' or 'plan_ready' within a 300s budget
(no silent Write/Edit, no crash, no timeout).

Affected:
- test/skill-e2e-plan-ceo-plan-mode.test.ts
- test/skill-e2e-plan-eng-plan-mode.test.ts
- test/skill-e2e-plan-design-plan-mode.test.ts
- test/skill-e2e-plan-devex-plan-mode.test.ts
- test/skill-e2e-plan-mode-no-op.test.ts (inPlanMode: false; tests the
  preamble plan-mode-info no-op path)

test/e2e-harness-audit.test.ts — recognize runPlanSkillObservation as a
valid coverage path alongside the legacy canUseTool / runPlanModeSkillTest.

test/helpers/touchfiles.ts — point the 5 plan-mode test selections and
the e2e-harness-audit selection at test/helpers/claude-pty-runner.ts
instead of the deleted plan-mode-helpers.ts.

Proof: bun test EVALS=1 EVALS_TIER=gate on these 5 files runs sequentially
in 790s and passes 5/5. Same tests were 0/5 on origin/main, on v1.0.0.0,
and on this branch with the SDK harness.

* test: align unit tests with slim resolvers + exempt 27MB security fixture

- test/skill-validation.test.ts: assert the slim Completeness Principle
  shape (Completeness: X/10, kind-note language) instead of the old
  Compression table. Remove the 3 tier-1 skills from the spot-check list
  (they intentionally don't carry the full Completeness Principle
  section). Exempt browse/test/fixtures/security-bench-haiku-responses.json
  (27MB deterministic replay fixture for BrowseSafe-Bench) from the 2MB
  tracked-file gate. The gate was actually failing on origin/main since
  the fixture was added in v1.6.4.0 — this is a side-fix to a real
  regression.

- test/brain-sync.test.ts: developer-machine-safe assertion for
  GSTACK_HOME override (compare config contents before/after instead of
  asserting the absence of a string that may legitimately exist).

- test/gen-skill-docs.test.ts: new tests for the slim — plan-review
  preambles stay under the post-slim budget (~33KB), Voice + Writing
  Style sections stay compact, and the slim Voice section preserves the
  load-bearing semantic contract (lead-with-the-point, name-the-file,
  user-outcome framing, no-corporate, no-AI-vocab, user-sovereignty).
  Update path-leakage scan to allow repo-root sidecar symlinks.

- test/writing-style-resolver.test.ts: assert the compact contract
  (gloss-on-first-use, outcome-framing, user-impact, terse-mode override)
  instead of the old 6-numbered-rules shape.

* chore: bump version and changelog (v1.13.1.0)

Slim preamble work + real-PTY plan-mode E2E harness on top of v1.13.0.0.
SKILL.md corpus -25.5% (3.08 MB → 2.30 MB, ~196K tokens). 5 plan-mode
tests go from 0/5 to 5/5 (790s sequential), the first time those tests
have ever passed. Side-fixes for the 27MB security fixture warning and
the sidecar-symlink double-count.

Reverts the Fan-Out directive accidentally restored to opus-4-7.md —
v1.10.1.0's overlay-efficacy harness measured -60pp fanout vs baseline
when the nudge was active. The intentional removal stays.

TODOS:
- Pre-existing test failures from v1.12.0.0 ship: RESOLVED on main + this branch
- security-bench-haiku-responses.json size gate: RESOLVED via warn-only + exemption

* feat(test): harness primitives — parseNumberedOptions + budget regression utils

claude-pty-runner.ts:
- parseNumberedOptions(visible) anchors on the latest "❯ 1." cursor and
  returns {index, label}[]; tests that route on option labels can find
  indices without hard-coding positions
- isPermissionDialogVisible(visible) detects file-grant + workspace-trust
  + bash-permission shapes (multiple regex variants)
- isNumberedOptionListVisible: replaced \b2\. word-boundary regex with
  [^0-9]2\. — stripAnsi removes TTY cursor-positioning escapes that
  collapse "Option 2." to "Option2.", and \b fails on word-to-word

eval-store.ts:
- findBudgetRegressions(comparison, opts?) — pure function returning
  tests where tools or turns grew >cap× vs prior run; floors at 5 prior
  tools / 3 prior turns to avoid noise on tiny numbers
- assertNoBudgetRegression() — wrapper that throws with full violation
  list. Env override GSTACK_BUDGET_RATIO

helpers-unit.test.ts: 23 unit tests covering empty/sparse/wrap-around
buffers for parseNumberedOptions, plus regression-floor + env-override
cases for findBudgetRegressions/assertNoBudgetRegression.

* test: register 6 real-PTY E2E touchfiles + UI-heavy plan fixture

touchfiles.ts:
- 6 new entries in E2E_TOUCHFILES keyed to the new test files
- 6 matching E2E_TIERS classifications: 3 gate (auq-format-pty,
  plan-design-with-ui-scope, budget-regression-pty), 3 periodic
  (plan-ceo-mode-routing, ship-idempotency-pty, autoplan-chain-pty)
- gate ones are cheap/deterministic; periodic ones run weekly

touchfiles.test.ts:
- update the "skill-specific change selects only that skill" count
  from 15 → 18 (plan-ceo-review/SKILL.md change now also selects
  auq-format-pty, plan-ceo-mode-routing, autoplan-chain-pty)

test/fixtures/plans/ui-heavy-feature.md:
- planted plan with explicit UI scope keywords (pages, components,
  Tailwind responsive layout, hover/loading/empty states, modal,
  toast). Used by plan-design-with-ui-scope and autoplan-chain tests.

* feat(test): 3 gate-tier real-PTY E2E tests

skill-e2e-auq-format-compliance.test.ts (~$0.50/run, 90-130s):
- Asserts /plan-ceo-review's first AUQ contains all 7 mandated format
  elements (ELI10, Recommendation, Pros/Cons with ✅/❌, Net,
  (recommended) label). Catches drift in the shared preamble resolver
  that previously took weeks to notice.
- Auto-grants permission dialogs that fire during preamble side-effects
  (touch on .feature-prompted markers in fresh user environments).
- Verified PASS in 126s.

skill-e2e-plan-design-with-ui.test.ts (~$0.80/run, 50-90s):
- Counterpart to the existing no-UI early-exit test. When the input plan
  DOES describe UI changes, /plan-design-review must NOT early-exit and
  must reach a real skill AUQ.
- Sends the slash command without args, then a follow-up message with
  the UI-heavy plan description (Claude Code rejects unknown trailing
  args). Asserts evidence does NOT contain "no UI scope".
- Verified PASS in 54s.

skill-budget-regression.test.ts (free, gate):
- Library-only assertion. Reads the most recent eval file, finds the
  prior same-branch run via findPreviousRun, computes ComparisonResult,
  asserts no test exceeded 2× tools or turns.
- Branch-scoped: skips with reason if the latest eval was produced on
  a different branch (cross-branch comparison would be noise).
- First-run grace (vacuous pass) when no prior data exists.

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

* feat(test): 3 periodic-tier real-PTY E2E tests

skill-e2e-plan-ceo-mode-routing.test.ts (~$3/run, 6-10 min/case):
- Verifies AUQ answer routing: HOLD SCOPE → rigor/bulletproof posture
  language; SCOPE EXPANSION → expansion/10x/dream language. Each case
  navigates 8-12 prior AUQs (telemetry, proactive, routing, vendoring,
  brain, office-hours, premise, approach) before hitting Step 0F.
- Periodic, not gate: navigation phase too slow for PR-blocking.
  V2 expansion to 4 modes (SELECTIVE + REDUCTION) when nav is faster.

skill-e2e-ship-idempotency.test.ts (~$3/run, 5-10 min):
- Builds a real git fixture with VERSION 0.0.2 already bumped, matching
  package.json, CHANGELOG entry, pushed to a local bare remote. Runs
  /ship in plan mode and asserts STATE: ALREADY_BUMPED echoes from the
  Step 12 idempotency check, OR plan_ready terminates without mutation.
- Snapshots VERSION + package.json + CHANGELOG entry count + commit
  count + branch HEAD before/after; fails if any changed.

skill-e2e-autoplan-chain.test.ts (~$8/run, 12-18 min):
- Asserts /autoplan phases run sequentially: tees timestamps as each
  "**Phase N complete.**" marker first appears. Phase 1 (CEO) must
  precede Phase 3 (Eng); Phase 2 (Design) is optional but if it
  appears, must sit between 1 and 3.
- Auto-grants permission dialogs that fire during phase transitions.

All three auto-handle permission dialogs (preamble side-effects on
fresh user envs without .feature-prompted-* markers).

* test: spell out AskUserQuestion everywhere instead of AUQ

Per user feedback: don't shorten AskUserQuestion to AUQ — the
abbreviation reads as cryptic. Apply across all the new code from this
branch:

- Rename test/skill-e2e-auq-format-compliance.test.ts →
  test/skill-e2e-ask-user-question-format-compliance.test.ts
- Touchfile entry auq-format-pty → ask-user-question-format-pty
  (touchfiles.ts + matching assertion in touchfiles.test.ts)
- Function rename navigateToModeAuq → navigateToModeAskUserQuestion
- Variable auqVisible → askUserQuestionVisible
- Outcome literal 'real_auq' → 'real_question'
- All comments + JSDoc + CHANGELOG entry write AskUserQuestion in full
- "AUQs" plural → "AskUserQuestions"

No behavior change. 49/49 free tests still pass.

* docs: harden v1.15.0.0 CHANGELOG entry against hostile readers

Per Garry: write the entry assuming a critic will screencap one line
and try to use it as ammunition.

Reframed the v1.15.0.0 release-summary to lead with new capability
(real-PTY harness, 11 plan-mode tests, +6 new) instead of fix-of-prior-
flaw narrative. Removed phrases that critics could weaponize:

- "0/5 → 5/5 passing", "finally pass", "∞ (never green)" — drop
- "Skill prompts get a 25% haircut" — implied self-inflicted bloat
- "770K → 574K tokens" — absolute number lets critics quote "still 574K
  of bloat"; replaced with relative "−196K tokens per invocation"
- "5 plan-mode E2E tests turned out to have never actually passed" —
  literal admission of long-term breakage; cut entirely
- Itemized "Fixed: tests finally pass" entry — moved to Changed with
  neutral "rewritten on the new harness" framing
- "Removed: harness with the runPlanModeSkillTest API that never
  worked" — replaced with "superseded by claude-pty-runner.ts"

Added concrete code receipts to pre-empt "it's just markdown":

- Net branch size: −11,609 lines (89 files, +7,240 / −18,849)
- 654 lines of TypeScript in test/helpers/claude-pty-runner.ts
- 8 new test files, ~1,453 lines of new TS code
- 23 helper unit tests + 6 new gate/periodic E2E tests

The deletion-heavy net diff (−11.6K lines) is itself the strongest
defense against the "bloat" critique — surfaced explicitly in the
numbers table.

Garry Tan 6209163900 v1.12.2.0 fix: /setup-gbrain day-two fixes (MCP scope, version parse, gh repo create order, smoke test) (#1187) 
* fix: parse gbrain --version without "gbrain" prefix

Installer's D19 PATH-shadow check compared `expected_version` from
package.json against `actual_version` from `gbrain --version`. The
output is "gbrain 0.18.2" with a literal prefix; `tr -d '[:space:]'`
left "gbrain0.18.2" which never matched "0.18.2", causing every
fresh install to exit 3 with a false-positive shadowing error.

Use `awk '{print $NF}'` to grab just the last whitespace-separated
token before stripping whitespace.

* fix(brain-init): drop --source flag before git init

gstack-brain-init used `gh repo create --source $GSTACK_HOME` before
running `git init` on that directory. gh requires --source to point at
an existing git repo, so the call fails with "not a git repository"
on first run. The fallback path (gh repo view) could only recover if
the repo was somehow pre-created — which it wasn't.

Fix: omit --source from `gh repo create`. The script's later steps
(git init, remote add, push) wire up the remote explicitly.

* fix(setup-gbrain): smoke test command + MCP user scope with absolute path

Three Step 5a/9 defects found running /setup-gbrain end-to-end:

1. Step 9 smoke test used `gbrain put_page --title ... --tags ...`,
   which doesn't exist. The real command is `gbrain put <slug>` with
   body piped on stdin. Updated to match.

2. Step 5a registered MCP with `claude mcp add gbrain -- gbrain serve`.
   Default scope is local (per-workspace), so other projects never saw
   gbrain. Cross-session memory is the whole point — user scope is
   correct.

3. Step 5a passed `gbrain` by bare name, relying on PATH being resolved
   when Claude Code spawns the subprocess. Fragile across shell configs.
   Use absolute path from `command -v gbrain` with ~/.bun/bin/gbrain
   fallback.

Also: remove any stale local-scope registration before re-adding, and
tell the user that open Claude Code sessions need a restart to see
the new mcp__gbrain__* tools (loaded at session start, not mid-session).

* chore: bump version and changelog (v1.12.1.0)

Also updates test/gstack-brain-init-gh-mock.test.ts to match the fixed
behavior of bin/gstack-brain-init (the assertion previously required
`--source`, which was the bug being fixed in 04185d8f).

Garry Tan aeea57f96a v1.12.1.0 fix: remove vestigial plan-mode handshake (#1185) 
* refactor: remove vestigial plan-mode handshake resolver

Delete scripts/resolvers/preamble/generate-plan-mode-handshake.ts and
its four question-registry entries. Split the authoritative
"Plan Mode Safe Operations" and "Skill Invocation During Plan Mode"
sections out of generate-completion-status.ts into a sibling
generatePlanModeInfo() export in the same module, wired at preamble
position 1 where the handshake used to live. Same text, new position.

The vestigial handshake told interactive review skills to emit an
A=exit-and-rerun / C=cancel AskUserQuestion before running their
interactive STOP-Ask workflow. That contradicted the authoritative
rule at the tail of completion-status.ts saying AskUserQuestion
satisfies plan mode's end-of-turn requirement. Skills now run
directly when invoked in plan mode, with each finding gated by
AskUserQuestion just like outside plan mode.

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

* test: rename plan-mode-handshake-helpers to plan-mode-helpers, strengthen smokes

Rename test/helpers/plan-mode-handshake-helpers.ts to
test/helpers/plan-mode-helpers.ts. Keep the write-guard helper that
asserts no Write/Edit tool call before the first AskUserQuestion
(this is what catches silent-bypass regressions the textual smoke
can't see). Rename the API: runPlanModeHandshakeTest to
runPlanModeSkillTest, assertHandshakeShape to assertNotHandshakeShape.
Extend the capture struct with exitPlanModeBeforeAsk.

Rewrite the four per-skill E2E tests (plan-ceo, plan-eng, plan-design,
plan-devex) as smoke tests that assert the skill's Step 0 question
fires first, not an A/C handshake. Each test picks a cheap first
answer (HOLD, TRIAGE, numeric score) so the run terminates quickly.

Keep test/skill-e2e-plan-mode-no-op.test.ts as the outside-plan-mode
non-interference regression, per codex outside-voice review: deleting
it would lose coverage for "the hoisted section stays quiet when plan
mode is absent."

Replace the gen-skill-docs.test.ts handshake describe block (lines
2778+) with a plan-mode-info describe block that:
- scans every generated SKILL.md under the repo root + every host
  subdir (.agents, .openclaw, .opencode, .factory, .hermes, .kiro,
  .cursor, .slate) and asserts "## Plan Mode Handshake" is absent
- asserts "## Skill Invocation During Plan Mode" lands in the first
  15KB of each of the four review skills' generated SKILL.md

Both assertions run on every bun test. A PR that re-introduces the
handshake resolver fails CI immediately.

Update test/e2e-harness-audit.test.ts to reference the renamed
runPlanModeSkillTest. Update test/helpers/touchfiles.ts entries to
point at the new resolver owner (generate-completion-status.ts) and
the renamed helper, and align per-skill touchfile keys.

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

* chore: regenerate SKILL.md across all hosts + refresh golden fixtures

Run bun run gen:skill-docs for every host to flush the vestigial
"## Plan Mode Handshake" section from every generated SKILL.md and
emit the hoisted "## Skill Invocation During Plan Mode" section at
preamble position 1 instead. Refresh the three golden-fixture
snapshots (claude, codex, factory) to match the new position.

No behavior change beyond the resolver swap in the prior commit.

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.

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

* 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.

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

* 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.

* 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.

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

* 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).

* 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).

* 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.
