v1.84.1.0 fix: default Codex and Claude to frontier models (#2835)

* fix: default cross-model workflows to frontier models

* chore: bump version and changelog (v1.82.1.0)

Co-Authored-By: OpenAI Codex <noreply@openai.com>

* fix: repair frontier eval budgets and workflow instructions

Preserve frontier models and quality thresholds while fixing truncated judge output, ordered section expansion, consent checks, QA scoring, and ship audit gates. Add regression coverage and refresh generated docs.

* fix: resolve workflow gaps exposed by frontier evals

Clarify plan-review ordering and fallback modes, preserve deploy readiness gates, honor configured merge methods, correct benchmark and canary contracts, and restore vendored installs on setup failure. Cover recovery with real-shell regressions.

Co-Authored-By: OpenAI Codex <noreply@openai.com>

* fix: use agent capture budgets for deploy evals

Multi-turn deploy and benchmark sessions were incorrectly limited to the single-call judge timeout. Use the existing capture tier and leave outer-test cleanup headroom, with a free policy regression test. Keep all behavioral assertions and frontier models unchanged.

* fix: clarify retro workflow and evaluate compare instructions

Include compare mode in the frontier judge excerpt, define metric sources and snapshot ordering, and preserve the existing prompt-size budget.

Co-authored-by: OpenAI Codex <noreply@openai.com>

* fix: make documentation release review and publication consistent

Review before commit, clarify changelog safeguards and unavailable reviewer modes, and preserve raw PR bodies across separate shell calls. Keep title sync in one shell and add regression coverage.

- **`under_codex`** — this session is already running INSIDE a Codex host, so spawning codex again is the same model reviewing itself at multiplied token cost (#2519). Print exactly one line: "[running under Codex — nested codex passes skipped; set GSTACK_FORCE_CODEX_REVIEW=1 to force]" and skip the codex invocations below; run the section's free in-host pass instead if it defines one.
- **`not_authed`** — installed but no credentials. Print: "Codex installed but not authenticated — falling back to a Claude subagent (same model family, not an outside model). Run `codex login` or set `$CODEX_API_KEY`." Fall back to the Claude subagent path.
- **`broken_install`** — the CLI is on PATH but cannot execute (spawn ENOENT, non-executable binary, missing vendor payload). Print: "Codex is installed but its binary cannot run — Codex passes skipped. Reinstall: `npm install -g @openai/codex`." Relay the probe's HINT lines and fall back to the Claude subagent path. This state exists because a missing binary used to land in the model probe's fail-open bucket and report `ready`, so every Codex pass was skipped silently (#2742).
- **`model_unusable`** — authed but the account cannot use its configured model (#2477: HTTP 400 on every call, usually a stale `model =` pin in `~/.codex/config.toml`). Relay the probe's HINT lines, tell the user the one-line fix (update the pin; `[notice.model_migrations]` names the replacement), and fall back to the Claude subagent path. The ~10s round trip is cached for 1h; timeouts fail open to `ready`.
- **`model_unusable`** — authed but the account cannot use gstack's selected Codex model (#2477: HTTP 400 on every call). Relay the probe's HINT lines, tell the user the one-line fix (set `GSTACK_CODEX_MODEL=<supported-model>` or pass an explicit `-c model=...` override), and fall back to the Claude subagent path. The ~10s round trip is cached for 1h; timeouts fail open to `ready`.

Set the Bash tool's `timeout` parameter to `600000` (10 minutes). It sits ABOVE the 540s wrapper deliberately, so the wrapper fires first and a stall surfaces as a diagnosable exit 124 instead of a harness kill that returns nothing. The wrapper resolves `gtimeout`, then `timeout`, then runs unwrapped, so it is safe on a macOS without coreutils. After the command completes, read stderr:

**No prompt argument.** `--base` is what scopes the review, and the positional `[PROMPT]` is mutually exclusive with it — passing both fails at argv parsing. Do NOT "fix" that error by dropping `--base` and keeping the prompt: a prompt-only `codex review` silently falls back to the **uncommitted working-tree** scope (`git status --short; git diff`), so it reviews the wrong changes and reports "no changes" on a clean tree. Prompt text describing the diff range does not change what the CLI feeds the reviewer. Unlike the adversarial pass above, which uses `codex exec` and really does run the git command it's told to, this path gets a pre-computed diff from the CLI — which is also why it needs no filesystem boundary.
