v1.34.2.0 fix wave: /codex review on CLI 0.130+, /investigate learnings, /sync-gbrain on Supabase (3 community-reported bugs) (#1478)

* fix(learnings): accept type:"investigation" in gstack-learnings-log

The /investigate skill instructed agents to log learnings with type:"investigation",
but bin/gstack-learnings-log:22 rejected anything not in
[pattern, pitfall, preference, architecture, tool, operational]. Every
investigation run exited 1 to stderr and the learning was dropped, silently
to the user.

Fix: add 'investigation' to ALLOWED_TYPES.

Regression test: round-trips a learning with type:"investigation" and asserts
exit 0 + file write; second test reads investigate/SKILL.md.tmpl and asserts
it emits the literal type:"investigation" string, guarding the
template/validator contract at both ends.

Fixes #1423. Reported by diogolealassis.

* fix(gbrain): engine detection survives gbrain ≥0.25 schema + non-zero doctor exit

freshDetectEngineTier() in lib/gstack-memory-helpers.ts returned engine:
"unknown" for every Supabase user on gbrain ≥0.25. Two stacking bugs:

1. execSync("gbrain doctor --json --fast 2>/dev/null") threw on non-zero
   exit. gbrain doctor exits 1 whenever health_score < 100, which is
   essentially every fresh install due to resolver_health warnings. The
   JSON output never reached the parser.
2. gbrain ≥0.25 shipped schema_version:2 doctor output that dropped the
   top-level 'engine' field entirely.

Result: every /sync-gbrain on Supabase logged 'engine=unknown' and skipped
all sync stages silently.

Fix:
- Replace execSync with execFileSync (no shell, no bash-specific 2>/dev/null
  redirect; portable to Windows).
- Recover stdout from the thrown error object so non-zero exits still parse.
- Fall back to reading gbrain's config.json (respecting GBRAIN_HOME env var,
  defaulting to ~/.gbrain/config.json) when doctor output doesn't surface
  an engine field.
- Add logGbrainError() helper that appends one-line JSONL to
  ~/.gstack/.gbrain-errors.jsonl on parse failure, so future regressions
  leave a forensic trail.

The "supabase" tier here means "remote postgres" in practice — gbrain
config uses engine:"postgres" for both real Supabase and any other
remote postgres (e.g. local-postgres-for-testing). Downstream sync code
treats them identically, so the label compression is intentional and
documented inline.

Regression test: existing detectEngineTier suite now isolates HOME +
GBRAIN_HOME + PATH to temp dirs (closes a flake source where the prior
tests would read whatever was on the reviewer's machine). New test
forces gbrain off PATH, writes a synthetic config.json with
engine:"postgres", asserts detectEngineTier() returns
engine:"supabase".

Fixes #1415. Patch shape contributed by Shiv @shivasymbl (tested on
gstack v1.31.0.0 + gbrain v0.31.3 + Supabase).

* fix(codex): /codex review works on Codex CLI ≥0.130.0

Codex CLI 0.130.0 made [PROMPT] and --base <BRANCH> mutually exclusive at
argv level. Step 2A of codex/SKILL.md.tmpl had always passed both (the
filesystem boundary prefix as the prompt argument + the base branch), so
every /codex review call died with:

  error: the argument '[PROMPT]' cannot be used with '--base <BRANCH>'

Fix: split Step 2A into two paths.

Default (no custom user instructions): bare 'codex review --base <base>'.
Codex's review prompt is internally diff-scoped, so the model focuses on
the changes against base. The filesystem boundary prefix is dropped here
because Codex 0.130 has no documented system-prompt config key
(probed -c 'system_prompt="..."' against 0.130 — the flag is silently
accepted but the value isn't applied). Skill files under .claude/ and
agents/ are public, so this is a token-efficiency concern, not a safety
one.

Custom instructions (/codex review <focus>): route through codex exec
with the diff written to a tempfile, inlined into the prompt between
explicit DIFF_START / DIFF_END markers. The boundary is preserved here
because codex exec isn't auto-scoped to the diff. The DIFF_START/END
delimiters tell the model where data ends and instructions resume, which
materially reduces prompt-injection hijack rates when the diff contains
adversarial content.

Note on bash semantics: codex's earlier review flagged the exec route as
"command injection via $_DIFF interpolation." That framing is wrong —
bash parameter expansion does not re-evaluate $(...) or backticks inside
the expanded value, so a diff containing $(rm -rf /) is plain string
data to codex exec. The real risk is prompt injection (model-side, not
shell-side), which the DIFF_START/END pattern mitigates.

Regression tests in test/codex-hardening.test.ts assert across BOTH
codex/SKILL.md.tmpl AND the generated codex/SKILL.md:
1. No 'codex review' invocation line combines a quoted-string OR variable
   positional argument with --base.
2. Step 2A still contains either bare 'codex review --base' OR 'codex
   exec' (guards against accidental deletion of both fix paths).

Fixes #1428. Reported by Stashub.

* test: raise timeouts for slow integration tests

Two test files were timing out at the default 5s on developer machines,
both pre-existing on origin/main but unrelated to this branch's bug fixes:

- test/gstack-artifacts-init.test.ts: 13 tests spawning real subprocesses
  via fake gh/glab/git shims in PATH. bun's fork+exec overhead pushed
  these past 5s consistently. Added a local test-wrapper that aliases
  test() with a 30s timeout (matches the brain-sync.test.ts pattern
  already in the repo).
- test/gstack-next-version.test.ts: one integration smoke test that
  spawns 'bun run ./bin/gstack-next-version' and parses the resulting
  JSON. The subprocess does a 'gh pr list' against the live GitHub API
  to enumerate claimed version slots. Network latency makes 5s tight;
  raised this single test to 30s.

No production code changed. The tests already passed deterministically
once given enough wall-clock time.

# Changelog
## [1.34.2.0] - 2026-05-13
## **Three filed bugs land in one PR. `/codex review`, `/investigate` learnings, and `/sync-gbrain` engine detection all work again.**
## **One CLI bump broke `/codex review`. One forgotten allowlist silently dropped years of investigation history. One stacking pair of bugs no-op'd `/sync-gbrain` for every Supabase user. All three are fixed with regression tests that lock the patterns in.**
`/codex review` died the day Codex CLI 0.130.0 shipped. The new CLI made `[PROMPT]` and `--base <branch>` mutually exclusive, and Step 2A had always passed both, so every review call exited before talking to a model. Fix: bare `codex review --base` for the default case, `codex exec` with a tempfile-backed prompt and DIFF_START/DIFF_END delimiters for the `/codex review <focus>` case. The exec route preserves the filesystem boundary instruction; the bare route ships without it because Codex 0.130 has no documented system-prompt config key, and the skill files those instructions guarded are public. Custom-instructions reviews now also defend against prompt injection from adversarial diff content (the delimiter pattern tells the model where data ends and instructions resume).
`/investigate` told the agent to log learnings with `type: "investigation"`, but `bin/gstack-learnings-log:22` rejected anything not in `[pattern, pitfall, preference, architecture, tool, operational]`. Every investigation run since the type was introduced wrote a stderr message and exited 1, silently to the user because nothing checked the exit code. Years of root-cause findings went nowhere. One-line fix: add `investigation` to `ALLOWED_TYPES`.
`/sync-gbrain` returned `engine: "unknown"` for every Supabase user on gbrain ≥ 0.25. Two stacking bugs. `execSync("gbrain doctor --json --fast 2>/dev/null")` threw on non-zero exit (gbrain doctor exits 1 whenever `health_score < 100`, which is essentially every fresh install due to `resolver_health` warnings), so the JSON output never reached the parser. And gbrain ≥ 0.25 dropped the top-level `engine` field from doctor output anyway. The fix recovers stdout from the thrown error object and falls back to reading `~/.gbrain/config.json` (respecting `GBRAIN_HOME`) when doctor doesn't surface an engine. Also moves the call from `execSync` to `execFileSync` so the shell redirect isn't a Windows-portability footgun, and adds error logging to `~/.gstack/.gbrain-errors.jsonl` so future parse failures are visible.
### The numbers that matter
Source: `bun test test/gstack-memory-helpers.test.ts test/learnings.test.ts test/codex-hardening.test.ts` (75 tests, 149 expect calls, 26 seconds) plus repo-relative smoke-tests against Codex CLI 0.130.0 and synthetic gbrain configs in temp `GBRAIN_HOME`.
| Bug | Before | After |
|---|---|---|
| `/codex review` on Codex CLI 0.130.0 | `error: the argument '[PROMPT]' cannot be used with '--base <BRANCH>'`, every call dies | Bare review works; `/codex review <focus>` routes through `codex exec` with DIFF_START/END markers |
| `/codex review <focus>` prompt injection surface | Diff content interpolated into prompt with no data/instructions boundary | DIFF_START/DIFF_END delimiters plus tempfile pattern, explicit "treat as data" instruction to the model |
| `/investigate` learning persistence | Exit 1 to stderr, no log written, invisible to user | Exit 0, learning appended, future sessions see prior root-cause findings |
| `/sync-gbrain` engine on gbrain ≥ 0.25 + Supabase | `engine=unknown`, all sync stages skip silently | Resolves to `supabase` via doctor stdout recovery or `~/.gbrain/config.json` fallback |
| Test isolation when running on a developer's real config | Tests read real `~/.gbrain/config.json`, pass-or-fail by reviewer's machine | Tests set `HOME` + `GBRAIN_HOME` + `PATH` to temp dirs, deterministic |
| Codex template regression guard | None, the broken state shipped to main | Static test asserts no `codex review` line combines a quoted prompt with `--base`, across both `.tmpl` source AND generated `SKILL.md` |
### What this means for builders
If you have been seeing `/codex review` fail on argv parsing since Codex CLI hit 0.130.0, run `/gstack-upgrade` to pick this up. If you ran `/investigate` between the type's introduction and this release, your learnings were dropped (they exit-1'd to stderr only, so there is nothing to recover), but going forward every investigation's root-cause finding is logged and retrievable. If you use gbrain with a Supabase backend and `/sync-gbrain` has been quietly doing nothing, this release brings it back. The three reporters (`Stashub` on #1428, `diogolealassis` on #1423, `Shiv @shivasymbl` on #1415) each filed a clean repro, and in Shiv's case shipped a tested patch. Credit where it is due.
### Itemized changes
#### Fixed
- **`codex/SKILL.md.tmpl` Step 2A** — replaced the unconditional `codex review "$boundary" --base <base>` invocation with a two-path branch. Default (no custom user instructions): bare `codex review --base <base>`. Custom instructions: `codex exec -s read-only "$(cat $_PROMPT_FILE)"` where `$_PROMPT_FILE` contains the filesystem boundary, the user's focus, and the diff between `DIFF_START` / `DIFF_END` markers. Probed `-c 'system_prompt="..."'` against Codex 0.130; the key isn't documented and silently no-ops, so the bare path ships without a re-injected boundary. Skill files under `.claude/` and `agents/` are public, so this is token efficiency, not safety. Contributed report by `Stashub` on #1428.
- **`bin/gstack-learnings-log`** — added `'investigation'` to `ALLOWED_TYPES` (was: `[pattern, pitfall, preference, architecture, tool, operational]`). Updated the usage comment to list valid types. Contributed report by `diogolealassis` on #1423.
- **`lib/gstack-memory-helpers.ts`** — rewrote `freshDetectEngineTier`. Three changes: switched `execSync` to `execFileSync` to drop the bash-specific `2>/dev/null` shell redirect (portable to Windows); recover stdout from the thrown error object so non-zero exits from `gbrain doctor` don't lose the JSON; fall back to reading `gbrain` config (respecting `$GBRAIN_HOME`, defaulting to `~/.gbrain/config.json`) when doctor output doesn't surface an `engine` field. Added `logGbrainError` helper that appends one-line JSONL to `~/.gstack/.gbrain-errors.jsonl` on parse failure. Patch shape contributed by `Shiv @shivasymbl` on #1415; tested against gstack v1.31.0.0 + gbrain v0.31.3 + Supabase.
#### Added
- **`test/gstack-memory-helpers.test.ts`** — `detectEngineTier` regression test for the schema_version:2 fallback path. Sets `HOME`, `GSTACK_HOME`, `GBRAIN_HOME`, and `PATH` to temp dirs (so the test doesn't read the developer's real `~/.gbrain/config.json` or invoke a real `gbrain`), writes a synthetic `{"engine":"postgres","database_url":"..."}` to the temp `GBRAIN_HOME`, asserts `detectEngineTier()` returns `engine: "supabase"`. The existing `detectEngineTier` `beforeEach`/`afterAll` blocks were also extended to isolate `HOME` and `GBRAIN_HOME`, closing a flake source where the prior tests would read whatever was on the reviewer's machine.
- **`test/learnings.test.ts`** — two tests for the `investigation` type. One round-trips `gstack-learnings-log` with `type: "investigation"` and asserts the file gets the entry. The other reads `investigate/SKILL.md.tmpl` and asserts it emits `"type":"investigation"` verbatim, caller contract guard against the template drifting to an invalid type.
- **`test/codex-hardening.test.ts`** — two tests applied to BOTH `codex/SKILL.md.tmpl` AND the generated `codex/SKILL.md`. The first parses Step 2A's section and asserts no `codex review` invocation line combines a quoted-prompt or variable positional argument with `--base`. The second asserts that Step 2A still contains either bare `codex review --base` OR `codex exec`, guards against accidentally deleting both fix paths in a future edit.
#### For contributors
- The probe for `-c 'system_prompt="..."'` support in Codex 0.130 lives in the plan, not the codebase. If a future Codex release exposes a real system-prompt config key, re-injecting the filesystem boundary in bare `codex review --base` is a 3-line follow-up patch to `codex/SKILL.md.tmpl`.
- The "supabase" engine tier means "remote postgres" in practice. Gbrain config uses `engine: "postgres"` for both real Supabase and local-postgres-for-testing, and `freshDetectEngineTier` maps both to `"supabase"` because downstream sync code treats them identically. The label compression is documented inline.
