Garry TanandClaude Fable 5	998aeb835f	fix(codex-probe): bash-native watchdog when no timeout binary exists; negative-cache the deterministic model 400 Stock macOS ships neither coreutils gtimeout nor timeout(1); the wrapper's fallback ran the command unwrapped, so a hung codex exec blocked the probe and the calling workflow indefinitely. The fallback now backgrounds the command, TERMs it at the deadline, and mirrors timeout(1)'s exit-124 contract — with the watchdog's stdout detached so an early finish never blocks a caller's $(...) capture on the orphaned sleep. MODEL_UNUSABLE is now negative-cached for 15 minutes (same exit-1 + hints from cache). The deterministic 400 is config-driven, so re-probing every preflight charged the affected user a 30s round trip plus real tokens per review section, forever. Editing config.toml — the fix — changes the cache signature and re-probes immediately; MODEL_PROBE_INCONCLUSIVE stays uncached.

fix(codex-probe): bash-native watchdog when no timeout binary exists; negative-cache the deterministic model 400

Stock macOS ships neither coreutils gtimeout nor timeout(1); the wrapper's
fallback ran the command unwrapped, so a hung codex exec blocked the probe
and the calling workflow indefinitely. The fallback now backgrounds the
command, TERMs it at the deadline, and mirrors timeout(1)'s exit-124
contract — with the watchdog's stdout detached so an early finish never
blocks a caller's $(...) capture on the orphaned sleep.

MODEL_UNUSABLE is now negative-cached for 15 minutes (same exit-1 + hints
from cache). The deterministic 400 is config-driven, so re-probing every
preflight charged the affected user a 30s round trip plus real tokens per
review section, forever. Editing config.toml — the fix — changes the cache
signature and re-probes immediately; MODEL_PROBE_INCONCLUSIVE stays uncached.

feat(codex): model round-trip probe — an unusable configured model fails fast with guidance (#2477 )

The auth probe accepts 'auth exists' as readiness, but a ChatGPT account
with a stale model pin in ~/.codex/config.toml passes it and then EVERY
mode dies with an HTTP 400 ('The <model> model is not supported when using
Codex with a ChatGPT account') and no pointer to where the model came from
— one report burned ~40 minutes and four invocations plus a strings dump
of the binary before finding the one-line config fix.

bin/gstack-codex-probe gains _gstack_codex_model_probe: a short
codex exec 'reply OK' round trip with the configured model, gated behind
the cheap auth probe at all three preflight sites (codex Step 0.5, the
shared codexPreflight in scripts/resolvers/constants.ts — which grows a
model_unusable CODEX_MODE branch — and autoplan's availability chain).
Verdicts: MODEL_OK (cached 1h, keyed on config.toml + auth.json mtimes so
a pin edit or re-login re-probes immediately), MODEL_UNUSABLE (exit 1,
prints the rejection plus HINTs at the model= pin and the
[notice.model_migrations] table), MODEL_PROBE_INCONCLUSIVE (timeout or
transient: FAIL-OPEN so network luck never wedges codex mode).

The 'Model not supported (HTTP 400)' Error Handling entry already shipped
in v1.64.0.0; Step 0.5's prose now routes MODEL_UNUSABLE to it.

test/codex-model-probe.test.ts drives all four behaviors against a stubbed
codex binary (invocation-counted cache hit, hint content, fail-open
polarity, mtime invalidation).

Fixes #2477

codex + Apple Silicon hardening wave (v0.18.4.0) (#1056 )

* fix: ad-hoc codesign compiled binaries on Apple Silicon after build

On some Apple Silicon machines, Bun's --compile produces a corrupt or
linker-only code signature. macOS kills these binaries with SIGKILL
(exit 137, zsh: killed) before they execute a single instruction.

Add a post-build codesign step to setup that runs only on Darwin arm64:
1. Remove the corrupt/linker-only signature (required — a direct re-sign
   fails with 'invalid or unsupported format for signature')
2. Apply a fresh ad-hoc signature

The step is idempotent, costs <1s, and is what Bun's own docs recommend
for distributed standalone executables. All four compiled binaries are
covered: browse, find-browse, design, and gstack-global-discover.
Failure is a non-fatal warning so Intel/CI builds are unaffected.

Fixes #997

* fix: prevent codex exec stdin deadlock with </dev/null redirect

codex CLI 0.120.0+ blocks indefinitely when stdin is a non-TTY pipe
(Claude Code Bash tool, background bash, CI). The CLI sees a non-TTY
stdin and waits for EOF to append it as a <stdin> block, even when the
prompt is passed as a positional argument.

Fix: add < /dev/null to every codex exec and codex review invocation
in the source-of-truth files (scripts/resolvers/*.ts and *.md.tmpl).
Generated SKILL.md files will be produced by bun run gen:skill-docs
in a subsequent commit (Tension D: template+resolver only, generator
is authoritative, not cherry-picked artifacts).

Affected source files (16 total invocations):
- scripts/resolvers/review.ts (4)
- scripts/resolvers/design.ts (3)
- codex/SKILL.md.tmpl (5)
- autoplan/SKILL.md.tmpl (4)

Fixes #971

* feat: codex/autoplan hardening + Apple Silicon coreutils auto-install

Hardens /codex and /autoplan against silent failures surfaced by the #972
stdin fix and #1003 Apple Silicon codesign. Six-layer defense:

1. **Multi-signal auth probe** (new Step 0.5 / Phase 0.5): env-based auth
   ($CODEX_API_KEY, $OPENAI_API_KEY) OR file-based auth
   (${CODEX_HOME:-~/.codex}/auth.json). Rejects false negatives that the
   old file-only check produced for CI / platform-engineer users.

2. **Timeout wrapper** around every codex exec / codex review invocation:
   gtimeout → timeout → unwrapped fallback chain. On exit 124, surfaces
   common causes + actionable next step. Guards against model-API stalls
   not covered by the #972 stdin fix.

3. **Stderr capture in Challenge mode** (codex/SKILL.md.tmpl:208):
   2>/dev/null → 2>$TMPERR. Post-invocation grep for auth/login/unauthorized
   surfaces errors that were previously dropped silently.

4. **Completeness check** in the Python JSON parser: tracks turn.completed
   events and warns on zero (possible mid-stream disconnect).

5. **Version warning** for known-bad Codex CLI (0.120.0-0.120.2, the range
   that introduced the stdin deadlock #972 fixes). Anchored regex
   `(^|[^0-9.])0\.120\.(0|1|2)([^0-9.]|$)` prevents 0.120.10 / 0.120.20
   false positives.

6. **Failure telemetry + operational learnings**: codex_timeout,
   codex_auth_failed, codex_cli_missing, codex_version_warning events
   land in ~/.gstack/analytics/skill-usage.jsonl behind the existing
   telemetry opt-in. On timeout (exit 124), auto-logs an operational
   learning via gstack-learnings-log so future /investigate sessions
   surface prior hang patterns automatically.

**Shared helper** (bin/gstack-codex-probe): consolidates all four pieces
(auth probe, version check, timeout wrapper, telemetry logger) into one
bash file that /codex and /autoplan source. Namespace-prefixed
(_gstack_codex_*) with a unit test that verifies sourcing does not leak
shell options into the caller. pathRewrites in host configs rewrite
~/.claude/skills/gstack → $GSTACK_ROOT for Codex, $GSTACK_BIN for
Factory/Cursor/etc.

**Apple Silicon coreutils auto-install** (setup:264): macOS lacks GNU
timeout by default; Homebrew's coreutils installs it as gtimeout to
avoid shadowing BSD utilities. ./setup now auto-installs coreutils on
Darwin (arch-agnostic — applies to Intel + Apple Silicon) when neither
gtimeout nor timeout is present. Opt-out via GSTACK_SKIP_COREUTILS=1
for CI, managed machines, or offline envs.

**25 deterministic unit tests** (test/codex-hardening.test.ts):
- 8 auth probe combinations (env precedence, whitespace, alternate
  $CODEX_HOME, corrupt file paths)
- 10 version regex cases including 0.120.10 false-positive guards
  and v-prefixed / multiline output
- 4 timeout wrapper + namespace hygiene (bash -n, gtimeout
  preference, set-option leak check)
- 3 telemetry payload schema checks (confirms env values + auth
  tokens never leak into emitted events)

**1 periodic-tier E2E** (test/skill-e2e-autoplan-dual-voice.test.ts):
gates the /autoplan dual-voice path — asserts both Claude subagent
and Codex voices produce output in Phase 1, OR that [codex-unavailable]
is logged when Codex is absent. ~\$1/run, not a CI gate.

Golden baseline + gen-skill-docs exclusion list updated for the new
codex path references and the 16 < /dev/null redirects from #972.

* fix: plan-review right-sized diff counterbalance (not minimal-diff default)

/plan-ceo-review and /plan-eng-review listed "minimal diff" as an
engineering preference without counterbalancing language. Reviewers
picked up on that and rejected rewrites that should have been approved.

The preference is now framed as "right-sized diff" with explicit
permission to recommend a rewrite when the existing foundation is
broken. Implementation alternatives section in CEO review gets an
equal-weight clarification: don't default to minimal viable just
because it is smaller. Recommend whichever best serves the user's
goal; if the right answer is a rewrite, say so.

Three-line tone edit per template, no voice / ETHOS / YC / promotional
content change.
