v1.17.0.0: setup-gbrain wireup ships the gbrain federation surface by garrytan · Pull Request #1234 · garrytan/gstack

garrytan · 2026-04-26T21:47:53Z

Summary

Replaces the dead consumers.json + /ingest-repo wireup in /setup-gbrain Step 7 with the real gbrain sources federation surface that gbrain v0.18+ shipped. After upgrade, your gstack memory (CEO plans, learnings, retros, builder profile) is searchable via gbrain search automatically.

Helper: bin/gstack-gbrain-source-wireup (NEW, ~370 lines bash). Idempotent. Manages a git worktree of ~/.gstack/, registers it as a federated source, runs gbrain sync. Flag surface: --strict, --uninstall, --probe, --source-id, --no-pull, --database-url. Multi-fallback source-id derivation. Multi-Mac collision detection (no ping-pong on shared brains). URL lock at startup defends against external ~/.gbrain/config.json rewrites mid-sync. Path validation refuses to rm -rf anywhere outside $HOME/.

Integration: setup-gbrain/SKILL.md.tmpl Step 7 invokes the helper with --strict. bin/gstack-brain-restore invokes it best-effort after the brain clone (2nd-Mac auto-wireup). bin/gstack-brain-uninstall calls --uninstall mode plus removes legacy consumers.json. bin/gstack-brain-init drops 60 lines of dead consumer-registration code.

Migration: gstack-upgrade/migrations/v1.15.1.0.sh. Idempotent, non-blocking. Runs the helper for users with brain-sync already configured. 4 skip conditions (HOME unset, sync_mode off, no .gstack/.git, helper missing).

Tests: 26 cases across 2 new test files. Helper coverage: fresh-state registration, idempotent re-runs, drift recovery (no gbrain sources update exists; remove + add), --strict failure modes, source-id fallback chain, --probe non-mutation, sync errors, --uninstall, --database-url URL lock (3 cases). Migration coverage: all 4 skip conditions + happy path + non-zero helper exit handling.

Pre-Landing Review

9 INFORMATIONAL findings, 0 CRITICAL. 5 auto-fixed:

Version-compare ordering: put floor first in sort -V stdin
_worktree_add_detached: surface git stderr via prefix (was 2>/dev/null)
ensure_worktree checkout-detach: same observability fix
do_probe worktree-status: explicit if block (not || && precedence trap)
do_probe + do_wireup: explicit set +e; rc=$?; set -e for return-code dispatch (was $? after if/||, fragile)
Migration: trim whitespace from gstack-config get output

2 cosmetic findings skipped (Python expanduser vs $GBRAIN_CONFIG, sync-failure log truncation).

Adversarial Review (Claude subagent)

7 CRITICAL findings, 5 hardened in code:

rm -rf path safety (was: rm -rf "$WORKTREE" would nuke / if env var set to empty//). Added safe_rm_worktree helper that refuses any path not under $HOME/.
jq dependency probe (was: silent fall-through if jq missing). check_source_state now hard-fails with a clear message.
Python heredoc warns on JSON parse failure (was: except Exception: pass defeated the URL lock silently). Now writes parse error to stderr; tells user the lock fell back.
Multi-Mac source-id collision (was: two Macs sharing one Supabase brain ping-pong the local_path metadata). Now: detect when existing path's basename matches local worktree's basename (likely another machine's local copy of the same brain repo), skip re-registration, sync from local.
DB URL redaction in sync-failure messages (was: failed gbrain sync echoed full DSN with password to stderr). Now sed-replaces postgres://... → postgres://***REDACTED*** and shows last 10 lines only.

Acknowledged-but-deferred:

GBRAIN_DATABASE_URL env exposure on Linux via /proc/$PID/environ. Linux-only; gstack is Mac-targeted today.
gbrain version parser brittleness if format changes from gbrain X.Y.Z.

Plan Completion

6 DONE as-specified, 4 CHANGED (within bounds), 5 DEFERRED (all in plan's NOT-in-scope list). Zero NOT-DONE items requiring user override.

CHANGED items: VERSION slot bumped (1.12.3.0 → 1.15.1.0 because main moved during branch life), migration filename matches actual VERSION, helper test count 13 (plan said 14) plus new migration test file, added --database-url flag beyond original plan (defensive vs config-rewriter race documented in commit e36ff7dd).

Documentation

USING_GBRAIN_WITH_GSTACK.md — added a row for gstack-gbrain-source-wireup in the bin helpers table. Describes federation registration (gbrain sources add + git worktree), idempotency, the flag surface, and that it replaces the dead consumers.json + /ingest-repo HTTP wireup from v1.12.x.
docs/gbrain-sync.md — fixed Step 5 of gstack-brain-init's flow. Was pointing at gstack-brain-reader add --ingest-url, which targeted an endpoint gbrain never shipped. Now describes the real flow: federate via gbrain sources add + worktree.

CHANGELOG.md, VERSION (1.15.1.0), README.md, CLAUDE.md, ARCHITECTURE.md, CONTRIBUTING.md, and TODOS.md reviewed; current.

Test plan

bun test test/gstack-gbrain-source-wireup.test.ts — 19/19 pass
bun test test/gstack-upgrade-migration-v1_15_1_0.test.ts — 7/7 pass
bun test full suite — 0 failures (3 pre-existing failures from a prior commit on main were resolved by main's own fixes; they no longer fail on this branch)
Live wireup against Garry's actual Supabase brain: source gstack-brain-garrytan registered at ~/.gstack-brain-worktree, URL lock confirmed via process env + active connection probe + simulated mid-run config flip (sync stayed locked on Supabase even after ~/.gbrain/config.json was rewritten to localhost:5436)

🤖 Generated with Claude Code

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

…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.

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.

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

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

/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).

…ion, 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.

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.

Queue advanced past v1.15.x while this branch was open. v1.15.0.0 landed on main (garrytan#1215) and garrytan#1233/garrytan#1234 claimed v1.15.1.0/v1.16.0.0 in the queue, so the next free PATCH slot is v1.16.1.0.

The previous bump landed at v1.21.0.0 because gstack-next-version advances past the highest claimed slot (v1.20.0.0 from #1252) rather than picking the lowest unclaimed. v1.16-v1.18 are unclaimed and v1.16.0.0 preserves monotonic version ordering on main once #1234 (v1.17), #1233 (v1.19), and #1252 (v1.20) merge after us.

Version-gate workflow rejected v1.20.0.0 because the queue moved during the windows-free-tests fix loop: v1.16.0.0 → garrytan/gbrowser-unleashed (PR #1253) [new since last bump] v1.17.0.0 → garrytan/setup-gbrain-run (PR #1234) v1.19.0.0 → garrytan/browserharness (PR #1233) v1.21.1.0 → garrytan/pty-plan-mode-e2e (PR #1255) [new since last bump] Two new sibling PRs landed slot claims while we iterated on Windows.

… slots The gate was rejecting any PR VERSION below the util's next-slot recommendation, even when the lower slot was unclaimed. This blocked PRs that legitimately want to land at an unclaimed slot below the queue max — which is what /ship should pick when the goal is monotonic version ordering on main (lower-numbered PRs landing first preserves order; the util's "advance past max claimed" semantics only optimizes for fresh runs picking unique slots, not for queue ordering on merge). New gate logic: 1. Hard-fail if PR VERSION <= base VERSION (no actual bump). 2. Hard-fail if PR VERSION exactly matches another open PR's VERSION (real collision). 3. Pass otherwise.

…unction (#1253) * feat: extend tunnel allowlist to 26 commands + extract canDispatchOverTunnel Adds newtab, tabs, back, forward, reload, snapshot, fill, url, closetab to TUNNEL_COMMANDS (matching what cli.ts and REMOTE_BROWSER_ACCESS.md already documented). Each new command is bounded by the existing per-tab ownership check at server.ts:613-624 — scoped tokens default to tabPolicy: 'own-only' so paired agents still can't operate on tabs they don't own. Refactors the inline gate check at server.ts:1771-1783 into a pure exported function canDispatchOverTunnel(command). Same behavior as the inline check; the difference is unit-testability without HTTP. Adds BROWSE_TUNNEL_LOCAL_ONLY=1 test-mode flag that binds the second Bun.serve listener with makeFetchHandler('tunnel') on 127.0.0.1 — no ngrok needed.

Adds a regex assertion that the `command !== 'newtab'` ownership exemption at server.ts:613 still exists — catches refactors that re-introduce the catch-22 from the other side.

RUN_DUAL_IMPL without dualImplInit in extra → status failed Was silently transitioning to dual_impl_done without recording worktree paths, making downstream tests/judge/apply impossible. 3.

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

Coverage estimate: 48% → ~75%. Mainline + migration script + key defensive paths all exercised. 26 tests total covering the new code surface. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * v1.16.1.0: rebump after queue-collision (PR garrytan#1233 took v1.16.0.0) CI's "Check VERSION is not stale vs queue" job (job 73105686380) failed with: "VERSION drift: PR garrytan#1234 claims v1.15.1.0 but the queue has moved — next free slot is v1.16.1.0." PR garrytan#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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v1.17.0.0: rebump again — bump-detection now classifies branch as MINOR CI's version-stale check (job 73106360896) failed: PR garrytan#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 garrytan#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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(dual-impl): /review pass — maxBuffer 50MB + cleaner squashed-commit message Two informational findings from /review pre-landing pass: 1. spawnSync default maxBuffer is 1MB. A large cumulative diff (e.g., 10k+ line refactor squashed across multiple commits) would silently truncate when piped to `git apply -3 -` in the cherry-pick fallback path. Set maxBuffer to 50 MB on every git invocation in worktree.ts. 2. Patch-fallback commit message used `git log --format=%s` across N commits, producing N subject lines in one ugly -m string. Now: single-commit case uses the original subject; multi-commit case uses "Apply <winner> implementation (N commits squashed)". Both BY-DESIGN risk (latent dualImpl undefined spread) and repo hygiene (untracked junk files predating this branch) deferred — not actionable here. 122 tests pass, 0 fail. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(dual-impl): Phase 3 — sub-agents.ts (runCodexImpl, runJudgeOpus, parseFailureCount) Four new exports for the dual-implementor tournament: - parseFailureCount(output): counts ✗ markers (bun) or ^FAIL lines (jest/pytest); returns max of the two so different runners report comparable signal. - parseJudgeVerdict(output): extracts WINNER: gemini|codex + REASONING from Opus output. Falls back to verdict='gemini' with explanatory reasoning if WINNER line is missing — better to ship one impl than fail on a parse quirk. - buildCodexImplArgv(opts): pure helper exposing the codex exec argv shape (exec + danger-full-access + -C cwd + reasoning=high). Extracted so tests can assert the invocation without spawning the binary. - runCodexImpl(opts): mirrors runGemini structure — file-path I/O, captured output, single retry on timeout. Operates inside an isolated worktree so danger-full-access is safe (no leakage to main cwd). - runJudgeOpus(opts): spawns claude --model claude-opus-4-7 -p with file-path I/O. Caller invokes parseJudgeVerdict on result.stdout to extract verdict. GSTACK_BUILD_JUDGE_TIMEOUT env var (default 10 min). 12 new tests cover parseFailureCount (5), parseJudgeVerdict (5), and buildCodexImplArgv (2). 134 tests pass, 0 fail. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(dual-impl): Phase 3 post-review HIGH+MEDIUM+LOW fixes Codex review surfaced four issues. All fixed: 1. HIGH — parseJudgeVerdict silently fell back to 'gemini' when WINNER line was missing. That defeats Phase 2's fail-closed semantics (dual_winner_pending without selectedImplementor → FAIL). Now returns verdict=null on malformed output; Phase 4 caller MUST treat null as hard failure. WINNER pattern is also now anchored to ^ so it doesn't match prose like "the WINNER: gemini is better here". 2. HIGH — runCodexImpl defaulted to 'danger-full-access', which is unsafe in linked git worktrees (shared .git, remotes, credentials with main cwd). A bad command could push --delete origin main from inside the worktree. Default is now 'workspace-write'; opts.sandbox or GSTACK_BUILD_CODEX_IMPL_SANDBOX env var allows opt-in to looser sandboxes. 3. MEDIUM — parseFailureCount returned 0 when no signal was detectable, making "could not parse failures" beat "1 real failure" in tie-breaking. Now returns `number | undefined`; phase-runner already fails closed when both impls have undefined failureCount. Also added priority-1 summary-line parsing ("3 failed" anchored to ^) for better cross-runner accuracy. 4. LOW — judge model was hardcoded 'claude-opus-4-7'. Now overridable via GSTACK_BUILD_JUDGE_MODEL env var. Tests updated accordingly: parseJudgeVerdict tests now check null fallback + mid-sentence rejection; parseFailureCount tests check undefined + summary-line priority; buildCodexImplArgv tests check workspace-write default + sandbox override. 137 tests pass, 0 fail. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(dual-impl): Phase 4 — cli.ts dispatch handlers + --dual-impl flag - Args.dualImpl: boolean field; --dual-impl CLI flag wired through parseArgs (now exported); HELP_TEXT exported and documents the flag. - parsePlan(content, { dualImpl }) stamps dualImpl=true on every parsed phase when the flag is set — single-impl plans are unchanged. - buildCodexImplPromptBody(phase, planFile): tournament-mode Codex prompt ("competing against Gemini, do NOT change test assertions, write minimal correct code"). - buildJudgePrompt({ phase, geminiDiff, codexDiff, geminiTestResult, codexTestResult }): Opus judge prompt with anchored WINNER:/REASONING: format and 5KB-trimmed diffs. - runPhase handlers for the 4 new actions: * RUN_DUAL_IMPL — createWorktrees + Promise.all([runGemini, runCodexImpl]); teardown + fail-closed if either impl crashes. * RUN_DUAL_TESTS — Promise.all([runTests(gemini), runTests(codex)]); parses failureCount from each; passes both into ApplyResultExtra. * RUN_JUDGE_OPUS — reads worktree diffs, runJudgeOpus with file-path I/O; parseJudgeVerdict; null verdict → fail-closed + teardown. * APPLY_WINNER — applyWinner cherry-pick; ALWAYS tears down worktrees (even on cherry-pick failure — Phase 4 invariant). - readWorktreeDiff helper: git diff baseCommit..HEAD with 50MB maxBuffer. - Exhaustiveness guard preserved (no _never violation on new actions). - 9 new tests cover --help text, parseArgs flag, and both new prompt bodies. 146 tests pass, 0 fail. bun build build/orchestrator/cli.ts → clean. gstack-build --help shows --dual-impl. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(dual-impl): Phase 4 post-review HIGH+MEDIUM fixes Codex review surfaced four issues. All fixed: 1. HIGH — readWorktreeDiff returned '' on git failure, letting the judge see empty evidence and pick arbitrarily. Now returns string|null; RUN_JUDGE_OPUS handler fails closed (teardown + status=failed) when either diff is null. 2. HIGH — implementations could pass tests with uncommitted edits, but applyWinner has nothing to cherry-pick. New countCommitsSinceBase helper + RUN_DUAL_IMPL now treats "neither implementor committed anything" as a catastrophic failure alongside timeouts and double-non-zero-exits. Single-implementor commit failures still let the test phase auto-select. 3. MEDIUM — RUN_DUAL_IMPL post-createWorktrees block had no cleanup guard. A throw from writeFileSync or unexpected Promise.all rejection would leak worktrees + branches. Now wrapped in try/catch/finally with teardown on any failure path; dualImplOk flag suppresses teardown on the success path (downstream phases own cleanup). 4. MEDIUM — APPLY_WINNER unconditionally tore down worktrees, including on apply failure — destroying the only copy of the winner's code. Now preserves worktrees on cherry-pick failure and surfaces paths/branches + manual-cleanup commands in the error message. Teardown only happens after a successful apply. 146 tests pass, 0 fail. bun build clean. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * feat(dual-impl): Phase 5 — README + SKILL.md.tmpl v1.15.0 + integration test - README: new "Dual Implementor Mode" section (workflow, auto-select rules, worktree isolation, recovery semantics, env vars). - SKILL.md.tmpl: version 1.14.0 → 1.15.0 in frontmatter + announce-version line. - bun run gen:skill-docs --host claude → regenerated build/SKILL.md. - skill-md.test.ts pinned to v1.15.0. - integration.test.ts adds a second dry-run that asserts --dual-impl announces "Dual Impl", "Dual Tests", "Judge Opus", and "Apply Winner" — and that the TDD steps (Test Specification, Verify Red) still run after handoff. - CHANGELOG: full Unreleased entry covering new flag, state machine extension, fail-closed paths, recovery semantics, and 42-test coverage delta (105→147). Verified: - 147 tests pass, 0 fail. - bun build build/orchestrator/cli.ts → clean. - gstack-build --help shows --dual-impl. - bun run gen:skill-docs regen → SKILL.md frontmatter version: 1.15.0. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * docs(dual-impl): Phase 5 post-review LOW + MEDIUM fixes - Clarify "each TDD phase" upfront (legacy 2-checkbox plans skip dual-impl silently — Phase 5 review LOW). - Document required CLIs (gemini, codex, claude) for --dual-impl with explicit note that orchestrator does NOT preflight check; missing Codex degrades into one-sided tournament. (Phase 5 review MEDIUM.) - Update stale "105 tests across 9 files" to "147 tests across 10 files" with full coverage breakdown including dual-impl primitives and integration tests. DEFERRED (Phase 5 review MEDIUM #1): hermetic non-dry-run integration test with fake GEMINI_BIN/CODEX_BIN/CLAUDE_BIN. Real handler paths (createWorktrees, Promise.all dispatch, applyWinner cherry-pick, teardown invariants) are exercised only through unit tests, not end-to-end. Acceptable for v1; landed feature is opt-in and small-blast-radius. 147 tests pass, 0 fail. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(dual-impl): Codex /review pass — 3 P2/P3 findings fixed Codex structured review (gpt-5.5, --base main, full diff) surfaced 3 valid correctness issues in the dual-implementor flow. All fixed; no P1 findings. GATE: PASS. [P2] cli.ts:739-741 — Zero-commit implementor still advanced to test/judge Old logic: only fail if BOTH sides committed nothing. If gemini committed but codex didn't (or vice versa), the no-commit side could pass tests on uncommitted edits and win auto-select, then applyWinner would fail with "No commits found". Fix: when EXACTLY ONE side committed, short-circuit dual-impl: skip RUN_DUAL_TESTS + RUN_JUDGE_OPUS, auto-select the committed side, jump straight to dual_winner_pending. Logs the warning so the user sees which implementor failed to commit. Both-failed and neither-committed paths unchanged (still fail-closed). [P2] sub-agents.ts parseFailureCount — pytest summary not matched Old regex: `^\s*(\d+)\s+fail` failed on pytest's `===== 2 failed in 0.10s =====` because of the leading `=====` decoration. Pytest projects would return undefined → fail-closed even when signal was present. Fix: priority-1 pytest pattern `^=+\s*(\d+)\s+failed\b` matches the decorated summary; priority-2 keeps the bare-line pattern for bun/jest/cargo; priority-3 marker count fixed from `^FAILED?\b` (which matched FAILE/FAILED) to `^FAIL(?:ED)?\b` (matches both FAIL and FAILED). 3 new pytest tests added. [P3] cli.ts:806-808 — Parallel dual-test logs collide Both runTests calls used `iteration: 1`, racing for the same log file `phase-N-tests-1.log`. testLogPath fields would point to one overwritten log. Fix: extended runTests with optional `logSuffix` param ('gemini'/'codex' for dual mode); resulting logs are `phase-N-tests-1-gemini.log` and `phase-N-tests-1-codex.log`. Default behavior unchanged when suffix omitted. 150 tests pass, 0 fail. bun build clean. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sub-agents): mergeOutputFile empty-fallback — preserve verdict stream when output file is empty When Codex applies edits inline but skips writing the report file, the output file is left empty. Without this fix mergeOutputFile replaces stdout with '' and parseVerdict returns 'unclear' — the review loop never converges. Fix: detect empty fileContent and fall through to merging stderr+stdout so the GATE PASS / GATE FAIL signal is preserved for the verdict scan.
