+name: Windows Scoped Tests
+
+# The path-scoped Windows free shard (ship-90-90 plan D). windows-smoke.yml is
+# still the required Windows check on every pull request, and the full
+# curated suite (windows-free-tests.yml) still runs nightly on main. This
+# workflow sits between them: when a pull request touches path, file-name or
+# process code, one windows-latest job runs the test files the pull request
+# changed that are in the curated Windows-safe subset.
+#
+# "Path, file-name or process code" (the windows-scope filter step):
+#   - file names: anything under a bin/ directory (shell entry points and
+#     skill hooks such as freeze/bin/check-freeze.sh, #3758), shell and
+#     PowerShell scripts, hosts/*/hooks, setup, bun.lock, the Windows
+#     curation (scripts/test-free-shards.ts, scripts/lib/windows-curation.ts,
+#     the Windows duration seed, windows-free-tests.yml), and code files whose
+#     names say path, spawn, exec, process, shell, launch, win32, windows,
+#     tmp, temp, symlink, state-root, slug, claude-bin, bun-isolation or
+#     script-invocation;
+#   - added or removed code lines that spawn processes or spell paths:
+#     child_process, spawn/exec calls, Bun.spawn, Bun.$, path.win32 and the
+#     other separator-sensitive path calls, process.platform/execPath, win32,
+#     tmpdir(), /dev/null, /tmp/, symlink, realpath, chmod, cygpath,
+#     USERPROFILE, homedir(), fileURLToPath and .exe. #3829's Windows break was
+#     one such line in a test it added: spawnSync(process.execPath, [...,
+#     '--config=/dev/null']), which native Windows Bun cannot open.
+# test/windows-path-scope-workflow.test.ts proves the filter catches #3758
+# and #3829 and passes over a docs-only and a pure-logic change.
+#
+# The windows-scoped-tests job is the check to read: it passes when nothing
+# is in scope (no Windows job ran) and otherwise requires the Windows job, so
+# a skipped run reports success. It is not one of the required checks, but
+# gstack-ship-queue ready and land refuse a head with any failed check, so a
+# red Windows job blocks the pull request it runs on: in a pull request that
+# touches path, file-name or process code, a changed curated test file has to
+# pass on Windows. A change to path or process code with no changed curated
+# test selects nothing; the nightly suite covers it.
+# gstack-pregate reads a job keyed on a dispatch input as manual, never a PR
+# obligation: this check runs on the pull request itself. A workflow_dispatch
+# run with the files input reruns chosen Windows-safe files on a branch.

+- **A stacked PR keeps its /ship receipt after its parent squash-merges, even when the receipt was written against main (GST-1199).** `gstack-ship-receipt carry` used to refuse with `RECEIPT_CARRY_PRODUCT_CHANGED` once the parent's hunks moved into main, forcing a full re-review of unchanged code. The carry now finds the newest reviewed commit that main already holds (`git merge-tree` into main changes no product path) and compares from there: an unchanged child carries as `stack parent <sha12> landed`, base edits next to the child's hunks go to `RECEIPT_CARRY_SCOPED_REVIEW`, and any other change still refuses. A parent that never landed never counts, even if the child's merge dropped its change.
+
+## [1.94.14.0] - 2026-11-03
+
+**`review_exclude_paths` keeps code it used to exclude, and the docs say exactly what the receipt check stops (GST-972).** Three ways to get code or a credential out of review under a base pattern are closed, each with a failing-first test in `test/review-exclude.test.ts`, and the receipt docs no longer over-claim.
+
+### Fixed
+- **Native binaries are code.** A `.node`, `.so`, `.dylib` or `.dll` file under a base pattern was excluded as binary content, and so was a compiled executable with a data extension. A binary file that starts with ELF, Mach-O (universal binaries included), PE, WebAssembly or `#!` magic is now kept as `code` whatever its extension. Binary here is git's own verdict on the bytes, read with no attributes from the tree as well as with the branch's, so a branch's `.gitattributes` (`*.png diff -binary`) cannot make an ELF read as text and skip the check (#3910).
+- **A NUL byte no longer makes code excludable.** A binary file was content unless its extension was on a short source list, so `.gradle`, `.sql`, `.tf`, `.groovy`, a `.p12` key store or an extensionless private key with a NUL byte was excluded. A binary file is now content only under a known content extension (images, fonts, media, documents, compressed archives, `.bin`, `.dat` and data blobs); every other binary file is kept as `code`.
+- **A branch's `.gitattributes` cannot get a file with a credential line excluded.** Marking `receipts/**` binary left the collector's added lines empty, so the secret-line keep rule saw nothing and the file was excluded. For a file git calls binary only because of its attributes, the rule now reads `git diff --text --no-textconv --no-ext-diff`, so the file stays in review and the plan lists it as `REVIEW_EXCLUDE_KEPT: secret-line`. Readers' own diffs still follow the branch's attributes and show that file as `Binary files differ`; reading such files as text in every reader's diff is a separate follow-up.
+- **`gstack-ship-receipt write --review-exclude` docs are exact.** The help, `docs/troubleshooting.md`, `docs/ship-policy.md` and the queue's refusal line said a receipt write alone cannot clear `field=review_exclude`. Write checks the digest against the base policy and does not read the review ledger, so a write given the refusal's `expected=` digest passes without a review. A mismatch proves only that the `--review-exclude` argument (or the digest the receipt recorded from it) differs from the head's selection, not what the readers read. The text now says that, and that the review rerun is the fix.
+
+## [1.94.13.0] - 2026-11-03
+
+- **A bare `--base main` reads origin/main in every review and ship bin (GST-1036).** `gstack-review-plan` now prints `REVIEW_BASE: <ref> <sha>` and names a lagging local base on stderr. `gstack-banned-terms`, `gstack-prose-lint --base`, `gstack-docs-candidate`, `gstack-design-detect.ts scan --changed` and `gstack-pr-shots --base` no longer merge against a stale local main and report lines the branch only inherited. They all use the one resolver gstack-gate-diff already used.
+- **`gstack-diff-scope` stops treating authorship files as auth (GST-1065).** `author-spec.md`, `AUTHORS`, `authority.ts` and `coauthors.ts` no longer raise a docs diff to gate class. Every other name with auth in it still does, including `auth.ts`, `/auth/`, `oauth`, `nextauthmiddleware.ts` and camelCase names like `useAuth.ts`.
+
+## [1.94.12.0] - 2026-11-03
+
+### Fixed
+
+- **Six markup tricks no longer pass a remote-loading or scripted SVG off as a chart (GST-940).** `&#60;/style>` or `&#60;!--` inside a `<style>` element, a comment that only an HTML parser ends early, a `>` inside a quoted attribute on the `<style>` tag, or a Unicode space before the `>` of `</style>` let CSS that loads a remote image read as a plain drawing, and a non-ASCII namespace prefix such as `<gé:script>` hid a script. Any of these could get the SVG a light review. The style walker now reads the `<style>` tag as quoted pairs with ASCII whitespace and its text as written, refuses any `&` in it, and reads its comments as CSS; a non-ASCII character in an element or attribute name keeps the SVG code. Over 62,805 unique SVG files, no other verdict changed.
+
+## [1.94.11.0] - 2026-11-03
+
+**A granted fix-check's clean read now counts at Step 16.** On gstack-evals#168 the owner granted one scoped fix-check, the reader read `9b0c56c..7ea1907` and found nothing, and `gstack-ship-release finish` still stopped with `STOP: behavior, tests or build inputs changed since review (tests/panel-kit-v3-1.test.ts)`, sending the test file the fix-check had read back through Steps 5 to 11.5. The review-loop exception could not help, because it is the owner accepting unreviewed edits and it never accepts a gate-edited test. The fix-check row also read `UNVERIFIED`, because it was logged without its `completed` and `converged` fields (GST-1130, GEVA-218).
+
+### Fixed
+- **`gstack-ship-release finish`** reads the newest `review-fix-check` row. When the row is a completed clean read on committed content, its `range_base` is a branch commit holding the reviewed tree, and the owner's recorded `review_loop_grant` names a stop head inside that range, every code or test path inside that range that is unchanged since routes as `fix_checked=` on the `ROUTE:` line, with a `FIX_CHECK: reviewed <paths>` line. That includes a gate-edited test. Authored docs still get the plan-item recheck, and a path edited after the fix-check still stops. A row that does not qualify prints `FIX_CHECK: not counted (<reason>)` and changes nothing.
+- **`gstack-review-log`** refuses a `review-fix-check` row that does not carry `completed` and `converged` as true or false, and keeps the start token for the retry. The refusal names the missing fields, so the row is fixed when it is written instead of reading `UNVERIFIED` at Step 11.5.
+
+### Tests
+- `test/ship-rereview-triggers.test.ts`: a fixture shaped like gstack-evals#168 (a round-2 pass, then a fix commit that edits the source and a gate-edited test) stops on main and passes finish once a clean fix-check row with its range base is logged through the real `gstack-review-log`. Negative controls: an edit after the fix-check still stops, and an ungranted row, a grant for another stop head, an incomplete row, a row with no range base, a range base that does not hold the reviewed tree, or a row logged on uncommitted content is not counted.
+- `test/review-log-findings.test.ts`: a `review-fix-check` row missing either field, or with a non-boolean value, is refused and keeps its start token; the complete row binds as verified.
+
+## [1.94.10.0] - 2026-11-03
+
+**Windows checks now run by path.** Windows Setup E2E, the 10-to-25-minute install test, no longer starts its Windows jobs on a pull request whose only install change is `package.json`'s version line, which the merge-train stamp puts on every pull request before it merges. Of the 61 pull requests in its last 100 runs (as of 2026-11-03), 37 changed no install file besides `package.json`. Its path list also gains `bun.lock` and the `bin/` scripts that the test or `./setup` runs. A new `Windows Scoped Tests` workflow runs the Windows-safe test files a pull request changed, on one Windows job, when the pull request touches path, file-name or process code, such as a hook script or a new `spawnSync` call. On the last 120 commits to main (through 923fc0a) it would have run on 50, with a median of one test file. It catches both Windows breaks the plan names: /freeze's path check (#3758) and a test that started Bun with `--config=/dev/null` (#3829). A red run blocks its pull request like any failed check, so this release also fixes #3829's test, which has failed every nightly Windows run since it landed. `windows-smoke` still runs on every pull request, and the full Windows suite still runs nightly.
+
+### CI
+- `.github/workflows/windows-setup-e2e.yml`: a Linux `windows-scope` job runs first and skips both Windows jobs when the only install change is `package.json`'s `"version"` line. Paths add `bun.lock`, `bin/gstack-config`, `bin/gstack-patch-names` and the scripts `./setup` sources or runs.
+- `.github/workflows/windows-scoped-tests.yml` (new): a Linux scope job reads the diff's file names and changed code lines, picks the changed files in the curated Windows-safe subset, and a `windows-latest` job runs them. The `windows-scoped-tests` check passes when nothing is in scope, so a skipped run still reports success. A `workflow_dispatch` with a `files` input reruns chosen Windows-safe files on a branch.
+
+### Tests
+- `test/review-risk-linear.test.ts`: the rules-hash case starts Bun with `bunIsolationArgs()` (`--config=NUL` on native Windows) instead of `--config=/dev/null`, which native Windows Bun cannot open (nightly Windows Free Tests run 41420490350, EINVAL).
+- `scripts/test-pr-profile.ts`: the new workflow is listed as free-lane only beside the other Windows workflows (test/free-fixtures.test.ts requires every workflow to be classified).
+- `test/windows-path-scope-workflow.test.ts`: runs both scope steps in a two-commit git repository. The filter catches #3758's and #3829's changed files and passes over a docs-and-stamp change and a pure-logic change. The Setup E2E scope skips a version-only `package.json` bump and runs on a dependency change. `windows-smoke` stays unfiltered, and no job that can skip is a required check.
+
+## [1.94.9.0] - 2026-11-03
+
+**A pull request can clear its remote gate obligation from a run with named flaky failures, once the owner grants it (GST-1096).** A timing flake in a test file the pull request never touched used to keep the pregate red with no way through but another paid run. `gstack-pregate clear --remote <lane> --run <id|url> --flaky-exception "<file>::<case>" --pr <n> --grant <approval id>` now accepts such a run when every failure is named from the run's own shard results and logs, at most three cases, each file outside the pull request's diff and its import closure, none paid and none a security scan test, and a gstack-approvals row in the owner's words binds the repository, PR, head, tree, lane, run attempt and cases. It covers the pregate only, and a red required CI check still needs its own green run.
+
+### Added
+- **`--flaky-exception`, `--pr` and `--grant` on `gstack-pregate clear`** (`lib/pregate/flaky-exception.ts`). Every job of the run attempt is reconciled (only test-shard jobs and their aggregate may fail), every planned shard needs a complete result, and each failed shard's log must name no failure its result leaves out. Without `--grant` the clear checks everything and prints the exact `gstack-approvals add` command, whose scope is a digest of everything the grant binds, so a grant can never be moved to another head or case list.
+- **`pass-with-exception`.** pregate.json records `exceptions`; `gstack-pregate verify` re-checks the binding offline and prints `PREGATE: pass-with-exception (<cases>; grant <id>)`; `gstack-ship-queue ready` accepts it and prints a `FLAKY_EXCEPTION:` line; the ship receipt records `flaky_exception`.
+- **docs/pregate.md#flaky-exception**, including why `base_red` is not used: it proves a failure by reproducing it on the base, and a timing flake passes there.
+
+### Tests
+- `test/pregate-flaky-exception.test.ts`: a red run with one named flake clears once the bound grant exists, and verify, ready and the receipt report it; refusals for an unnamed or extra failure, a case that did not fail, more than three cases, an unattributed failure, a failed non-shard job, a missing result or log, a timed-out shard, a log failure the result omits, a file in the diff or its import closure, a paid or security test, another head, another PR head, a newer run, a run from another repository or fork, a stale or unfinished run, a moved attempt (also after the inventory runs), and a grant with another scope, outcome or speaker; ready still refuses red CI, and refuses an exception granted for another PR or head. The printed grant command quotes case names for the shell. These tests failed before the change.
+
+## [1.94.8.0] - 2026-11-03
+
+**`gstack-approvals render` no longer puts the owner's exact words, autoplan run ids or plan hashes into PR bodies on public repositories (GST-1160).** On a public repo, /ship pasted the full `## Approvals` table into the PR description. That table carries the owner's verbatim quote, the run id and the plan sha256, and GitHub keeps every earlier version of a description in its edit history, which no API can delete.
+
+### Fixed
+- **`bin/gstack-approvals render`** asks gh for the visibility of the repository gh picks by default (`GH_REPO`, its default repo, an `upstream` remote) and of the `origin` repository the PR is opened against. When every one of them is private (or internal), it prints the full table as before. When any is public, or gh can't tell, it prints only `Approved: yes|no (record r-<12 hex>)`. The record id is a hash of the row ids, so the Captain can match it to the private record without anything identifying being published. A stderr line, `APPROVALS_RENDER: redacted (repository visibility …)`, says which mode was used.
+- **`--full`** prints the full table when gh can't read the visibility and you know the repository is private. It never prints the full table for a repository GitHub reports as public. `gstack-approvals list` still shows the full record.
+- **/ship Step 19** (`ship/sections/capy-pr.md`) says a public repository gets only the one line, and never to pass `--full` for a PR body.
+
+## [1.94.7.0] - 2026-11-03
+
+### Fixed
+
+- **/autoplan no longer stalls after a review phase when its reviewers share your machine (GST-1161).** A session installed from the skill's own folder gets an install verdict with no project, and its `GSTACK_LAUNCH` line points admission at that file. When a reviewer on the same machine ran `install.sh --for review-voice` from the project, it wrote a review-voice verdict keyed by that project. Admission read the project's file first, so the next `gstack-autoplan submit` refused with INSTALL_UNVERIFIED ("certified for=review-voice") until `install.sh --for autoplan` was run again. Both admission readers (`lib/install-verdict.ts` and `bin/gstack-install-verdict.sh`) now skip a review-voice verdict at the project path when the session's launched `GSTACK_INSTALL_VERDICT` exists, since a review-voice verdict can't admit any workflow. With no launched verdict, the review-voice refusal and its fix line are unchanged. `scripts/install.sh` and its user-scope copy don't change.
+
+## [1.94.6.0] - 2026-11-03
+
+Two opt-in Claude Code hooks so a model actually runs gstack's skills, both off by default (GST-1088). `./setup --skill-routing` adds a UserPromptSubmit hook that names the gstack skill a prompt fits, scored against each installed skill's `triggers:` with no model call. `./setup --skill-contracts` adds a Stop hook that blocks once when a skill with a `contract:` block ends without its required outputs (a report with real values, a test after the last edit, the specialist and adversarial dispatches). `gstack-skill-route --explain` shows how a prompt scores; `gstack-skill-contract check|report|waive` checks a transcript, lists misses and acknowledges a waiver. Turn either off with `gstack-config set skill_routing off` or `gstack-config set skill_contracts off`. Docs: docs/skill-routing-and-contracts.md.
+
+## [1.94.5.0] - 2026-11-03
+
+**Security: the lean /autoplan reviewer no longer gets `.envrc`, `.env-production` or a key pasted into an ordinary file (GST-1164, #3914).** Since v1.93.36.0 (#3897), the lean run puts the branch's draft code into a prompt that goes to an outside model provider. It left out only some secret-named untracked files: `.env` and `.env.*`, but not `.envrc` or `.env-production`. It applied no name rule to tracked files and no content check at all. So a direnv `.envrc`, a `.env-production`, a committed or edited secret file, or a key sitting in any source file could reach the provider.
+
+### Fixed
+- **`lib/autoplan-lean.ts` `captureDraft`:** the secret-name rule now covers the whole `.env*` family, `.envrc` included, every `*credentials*` name, `_netrc`, `.pgpass`, `*.jks` and `id_*_sk` keys. Matching files are never diffed, tracked or untracked, and the draft names each one it left out. A secret-named file that git sees renamed or copied on the branch stays out under both names, even when the new name looks ordinary. A secret moved without `git add`, copied unchanged, or renamed and heavily edited still reaches the draft under its new name, guarded only by the content check. Every other file's patch goes through gstack's redact engine (`redactFindingSpans`), so a key in an ordinary file reaches the reviewer as `<REDACTED-…>`. A patch the engine can't redact safely, including one over 1 MiB, is left out with a note.
+
+### Tests
+- `test/autoplan-lean.test.ts`: an untracked `.envrc`, `.env-production` and six other secret files stay out of `draft.diff` and the prompt; a committed and edited `.envrc` stays out of the tracked diff, and so do an `.envrc` renamed to `.envrc.local` and a `.pgpass` renamed to `pg.txt`; a fake key in an untracked file and in a working-tree edit to a tracked file comes out redacted. All four fail on main at b42ad1e.
+
+Thanks to the /ship pre-landing review of #3901, which filed the finding.
+
+## [1.94.4.0] - 2026-11-03
+
+- The captain skill, the CREW template, the lane brief, docs/captain.md and the Capy gstack skill now follow R65 instead of telling a lane that every fix needs a one-round, eng-only plan. A bug fix is exempt from plan review (`gstack-autoplan next --kind fix`; the brief's reason is `bug fix (R65)`), and its PR carries a repro on current main or a failing test written first. A feature gets the lean run (`--kind feature`): one reviewer reading the plan and the draft code together. The S1 and audited-problem-list exemptions are unchanged.
+
+## [1.94.3.0] - 2026-11-03
+
+**`gstack-ship-preflight` no longer trusts a local `origin/HEAD` when origin can't say its default branch.** Preflight fell back to the local `origin/HEAD` whenever `git ls-remote --symref origin HEAD` failed or named no branch. With no local `origin/HEAD`, it went on from the default branch itself and merged the given base into it. When a PR-branch clone's `origin/HEAD` named the feature branch, it refused that branch as "on the base branch". Now a failed `ls-remote` stops with `git ls-remote origin HEAD failed: …; restore access first` before anything merges. A remote HEAD that names no branch (a detached HEAD, or a server that sends no symref) falls back to the shared default-base order in `lib/default-base.ts`, which uses the local `origin/HEAD` only when it doesn't name the checked-out branch, its upstream or HEAD's commit. The default-branch check now runs after the fetch, so a failed fetch still reports the fetch.
+
+### Fixed
+- **`docs/eval-calls.md`, `docs/eval-models.md`**: the default `--base` now matches base resolution: origin/HEAD's branch unless it names the checked-out branch, its upstream or HEAD's commit, then the PR's base, the remote's live HEAD, `main` or `master`.
+
+### Tests
+- `test/ship-preflight.test.ts`: with `ls-remote` failing and the fetch working, preflight stops before merging in two cases. One is the default branch with no local `origin/HEAD`, where main exited 0 and merged `release` into `main`. The other is a feature branch that the local `origin/HEAD` names, where main stopped as "on the base branch". When `ls-remote` prints only a sha, the default branch still stops as the base branch (main exited 0) and the feature branch goes on.
+
+## [1.94.2.0] - 2026-11-03
+
+### Fixed
+
+- **More recursive deletes keep the security class (GST-942).** `fs.rmSync(path.join(dir, "x"), { recursive: true })`, a `)` inside a comment before `recursive: true`, `fs.rm`/`fs.promises.rm`/an imported `rm`, and a new call a formatter split across lines all slipped past the rule, because it stopped reading at the first `)` and read one line at a time. The review depth could then drop to light on real recursive-delete code. The rule now reads up to 500 characters after `rmSync(` or `rm(` across the file's changed lines, still in linear time. An edit to one line of an existing split call is still read on its own.
+
+## [1.94.1.0] - 2026-11-03
+
+### Fixed
+- **The secrets check no longer reads a file name or dict key inside a call as a credential (GST-1064).** `key = json.loads(files.get("key.json", ""))` failed pregate with `PREGATE_SECRETS` (`env.kv`): eight distinct letters in `"key.json"` reach the entropy bar, so the call's argument looked like a secret. So did `token = resp.json().get("access_token")`. The first argument of a lookup call (`get`, `getenv`, `read`, `load`, `loads`, `open`, `pop`, `fetch`) that is a lowercase file name or a snake_case key of two or three words now counts as a name. Any other call still reports a password-shaped literal (`make_password("orange_monkey_pass")`, `bcrypt.hashpw(...)`), and so do a later argument or fallback (`os.getenv("SECRET_KEY", "orange_monkey_pass")`), a real key in quotes or in a `.env` line, and a kebab passphrase (`decrypt("prod-signing-key")`). The entropy bar is unchanged.
+
+## [1.94.0.0] - 2026-11-03
+
+- CI is now the one full test run. When a verified CI run already passed at the exact, clean tree, `gstack-pregate`'s tests stage and /ship's test lanes use it instead of running the suite again (GSTA-258, R65 item 1). The tests stage looks up the newest verified run at HEAD under the base branch's `run_profiles` by itself (`CI_CARRY: accepted …`; `--no-ci-carry` turns it off). A /ship lane carries only when the base branch's `.gstack/pregate.json` maps its exact command in the new `ship_lanes_from` key, and only when the run's `tree.json` covers the lane's inventory; gstack maps `bun run test` to its Free Tests run. A carried lane prints `LANE: <label> carried run=<id>/<attempt>` and is recorded as an explicit CI-sourced evidence row (`gstack-evidence record-ci`), never as a local run. Dirty trees, fork runs, stale runs and a newer red or running run never carry.
+- A lane that already passed at the same tree, command and runtime is reused instead of rerun (`gstack-evidence run --reuse`, the default from `gstack-ship-preflight` and `finish`): a newer failure vetoes an older pass, and the reused row keeps its original timestamp, so the 24-hour age limit still measures the real run.
+- /ship runs beside CI: on a repo that maps its lanes, Phase 2 pushes early (`gstack-ship-release push --early` runs the secrets scan and the sealed guard first), `finish` defers a mapped lane it cannot carry yet (`EVIDENCE: DEFERRED`), and the new `gstack-ship-release accept` carries it from the green run at the final pushed head and reruns the pregate there. `gstack-ci-carry find|wait` checks or waits for that run, and the ship receipt records `ci_carried`. See docs/pregate.md#ci-carry.
+- On a small machine, the remote gate obligation clears from the same carried run (through `remote_gate_runs` and its inventory check) when the files left over are only ones the gate skips, such as gstack's paid evals. Before, that remainder made the gate report `tests=0` and `clear --run` refuse it as `paid_only`, so nothing could clear it.
+- On gstack itself, a green Free Tests run at the same tree is now the default way the remote gate obligation clears, and the Ubicloud VM (`gstack-pregate --stage tests --remote`) is an opt-in. The uncleared obligation names the CI route first: push, `gstack-ci-carry wait --base main`, then rerun `gstack-pregate --allow-repo-commands`. On a branch behind main, dispatch Free Tests on the branch (`gh workflow run free-tests.yml --ref <branch>`), because a `pull_request` run tests the merge commit, another tree.
+- `gstack-evidence record-ci` now finds and verifies the CI run itself (`record-ci --label <L> --base <base> -- <command>`), so no caller can hand it run ids or a test count. `finish` writes its preflight-only pregate run to its own file, so the full `.gstack/tmp/pregate.json` stays in place until `accept` replaces it.
+
+## [1.93.42.0] - 2026-11-03
+
+**The stamp checks name the branch's lines by position, and the carry and finish accept a kept VERSION claim (GST-979, GST-980).** After GST-963, three gaps were left in the checks that accept a stamp commit, all found by the #3862 reviewers. A base line whose text duplicated a line the branch added got the branch's fork-version bound, so a hand edit of that base copy passed the tree receipt. When a train slot kept its claimed VERSION, a base line moved down to that version also read as a stamp. And the /ship receipt carry and finish refused the fork-version row move the restamp now makes: the carry kept the branch-added row in both product patch-ids (`RECEIPT_CARRY_PRODUCT_CHANGED`), and with a kept VERSION claim the carry and finish read every change as product or behavior.
+
+### Fixed
+- **`lib/stamp-only.ts`:** `BranchSide` carries the positions of the branch's lines, and `stampOnlyLine` takes the removed line's position. Only a line at a branch-added position gets the fork-version bound. When the version does not move, only such a line may change.
+- **`lib/restamp.ts`:** `parseUnifiedDiff` records each removed line's position on the old side, which the tree receipt, the train checks and finish's `stampedFiles` pass along.
+- **`lib/ship-receipt.ts`, `lib/ship-bin-common.ts`:** `stampOnlyText` and `stampedFiles` accept a kept VERSION claim for the branch's own rows and nothing else.
+- **`bin/gstack-ship-receipt` carry:** a stamp file the branch changed as product, whose only change since the reviewed head is a stamp on its own rows and which the base did not touch, is left out of the product comparison. The carry records `a stamp on the branch's own rows (<file>)` as the reason. It reads that file line by line. Only lines at the branch's own positions may move, and the file must keep its reviewed mode, so a version edit on a base line of the same file or a mode change still refuses, as does a product edit anywhere else.
+
+### Tests
+- `test/tree-receipt-stamp-sensitive.test.ts`: the bound holds only at the branch line's position, and a kept VERSION refuses a base line moved down.
+- `test/restamp-mentions.test.ts`: a hand move of a base row whose text the branch duplicates reads `TREE: changed`, and the carry follows the fork-version row stamp but still refuses a product edit beside it, a hand version edit on a base line of the same file, and a mode change.
+- `test/gstack-ship-receipt-docs.test.ts`, `test/ship-rereview-triggers.test.ts`: the carry classifier and finish accept the kept-claim row move and refuse a base row moved the same way.
+
+On main, five of the seven new tests fail. The other two, the carry's refusals of a base-line version edit and a mode change, pass on main, which refuses every such carry; they fail on the broader first version of this fix.
+
+## [1.93.41.0] - 2026-11-03
+
+**Codex outside reviews report their token usage (#2948).** Codex already emits token counts in its `--json` events, and gstack used to throw them away. When `lib/outside-review-result.ts` is given an events file, it now prints `OUTSIDE_USAGE: input=… cached_input=… output=… reasoning_output=…` (only the counters Codex reported), or `OUTSIDE_USAGE: unknown`, on every verdict.
+
+### Changed
+- **Every Codex outside voice that runs `codex exec --json`** (/review, /ship, /autoplan, the plan reviews) now prints one more stdout line, `OUTSIDE_USAGE:`, after `VERDICT:` and `FINDINGS:`.
+- **One usage parser** (`usageFromEvents`, now in `lib/outside-review-result.ts` and re-exported by `lib/outside-voice-runner.ts`). A cumulative `total_token_usage` snapshot wins; without one, the latest `turn.completed` usage does, because Codex reports the session's running total there. It adds cached, cache-write, reasoning and total counters when the events carry them.
+
+Thanks to @omicron-soft for the report. Storing usage in review-log rows, the native `codex review` path and a token column in /ship come in a follow-up.
+
+## [1.93.40.0] - 2026-11-03
+
+### Fixed
+
+- **/ship and /review exploratory QA no longer write reports into your project (GST-969).** /ship Step 9.2.1 and /review Step 4.7 used to put its QA reports, deadline file and captured evidence in `.gstack/qa-reports/` inside the repository under review. In a project that doesn't ignore `.gstack/`, those files showed up as untracked changes, so they could land in the PR and change the tree the review certified. The new `gstack-qa-evidence report-dir` command creates a fresh run directory under `.gstack/tmp/qa-reports/` and adds `/.gstack/tmp/` to the repository's git exclude file, and both QA steps now use it. It refuses a symlinked `.gstack`, a `.gitignore` rule that un-ignores `.gstack/tmp`, and a directory outside a git repository. /qa keeps its `.gstack/qa-reports` output directory.
+
+## [1.93.39.0] - 2026-11-03
+
+**/ship on Capy stops an outside voice that hangs and records it as missing, never as converged or as an unavailable Codex CLI (GST-1104).** TRUT-7's /ship run had two outside voices end with no result (gpt-6.1-sol stopped after 20 minutes; grok-4.7 used 16.9M tokens before it was stopped), and its Step 11 row read `outside_provider: codex`, `outside_status: unavailable`, `converged: true`.
+
+### Fixed
+- **`lib/capy-review-pass.js`**: an outside voice still running with no output after `input.stuckMs` (20 minutes by default) is stopped. One that hangs, finishes empty, or stops or fails without leaving findings is collected as unavailable coverage (`COLLECT_UNAVAILABLE:`); one that stops or fails after writing findings is collected normally, so its findings are kept, and Step 11 goes on to judge the native voice instead of stopping the pass with nothing recorded. Other readers still stop the pass as before.
+- **`lib/capy-review-pass.js`**: Step 11 returns an `OUTSIDE_RECORD:` line with `outside_provider: host-subagent`, the model that ran and its status, for the review-log rows to copy instead of the template's `codex`. When the voice was unavailable, the line tells the parent to write that voice its own row first (`status: unavailable`, `completed` and `converged` false), so the native row's convergence no longer stands in for it.
+- **`docs/unattended.md`**: "The outside voice on Capy" describes the stop, the unavailable record and the new fields.
+
+## [1.93.38.0] - 2026-11-03
+
+- **Review collector and blocker count follow what the reader said (GST-1031).** A native adversarial finding that states `Blocks: no` and one Severity now collects once, at that severity, on every review class; a numbered finding heading keeps its body (located or numbered bullets, a bold subheading, a located paragraph) so its Severity line no longer splits off as a second CRITICAL record. A closing summary such as "so nothing is CRITICAL" is marked `summary_candidate`, and lead judgment may lower it with a reason that `judge` records as `dismissed`. A CRITICAL whose reader writes the field `Blocks: no` no longer counts as a blocker in `REVIEW_LOOP`'s ledger count (classify does the same for a finding that carries `stated`; Step 9.4 does not copy it yet). Decision 3.5's fix-check pass takes a `review-fix-check` start token even when given `logStart: ["review"]`, so it is never counted as a pass. `gstack-ship-release finish` routes a `scripts/harness-version.json` edit that only records non-behavioral pins at the same version as release metadata.
+
+## [1.93.37.0] - 2026-11-03
+
+**Eval planning prices Claude Haiku 5.5, GPT-6 Luna and Gemini 4 Argon, and the Codex docs name the current OpenAI tiers (#3640, #2943).** Before, `gstack-eval-plan arms --arms claude-haiku-5-5` stopped with EVAL_PRICE_MISSING because `lib/pricing.ts` had no row for it. docs/hosts.md and the /codex example still named gpt-5.6-sol as the current Sol model.
+
+### Added
+- **Price rows** for `claude-haiku-5-5` ($0.10 / $0.50, cached $0.01, standard tier up to 100,000 tokens), `gpt-6-luna` ($0.10 / $0.50, cached $0.01) and `gemini-4-argon` ($4.00 / $20.00, cached $0.20). Each row cites its provider page. Argon uses the rates that start on 2026-12-01, so estimates never come in low after that date. A repository's model-policy document that names one of these models now gets it as an eval arm.
+
+### Changed
+- **docs/hosts.md and /codex** name `gpt-6-astra`, `gpt-6.1-sol` and `gpt-6-luna` as the current tiers. They also say the bounded-scope overlay still applies only to `gpt-5.6-sol` until it has its own eval.
+
+Thanks to @exGeni (#3640) and @DanCanadian (#2943) for the reports. The TypeSafe Jev rows from #3640 are not included, because a $0 output price breaks the price table's rule that every row has an output price.
+
+## [1.93.36.0] - 2026-11-03
+
+- **/autoplan R65 defaults: no review for bug fixes, one lean review for features.** `gstack-autoplan next --kind fix` prints `AUTOPLAN: not needed (bug fix; R65)` and `status=skipped run=-` and writes nothing; the PR still needs the bug's proof. `--kind feature`, now the default for an unattended Capy run, runs the eng phase alone with one native reviewer whose brief merges the CEO and Eng lenses (Design and DX only when scope detects them), reads the draft code (a diff against `--base`, hashed into the snapshot, or an honest `DRAFT: none`), always asks "Any outside terms, licences or rights involved?", and has no outside voice, one round, one gate revision and no carry check. The reviewer's result must name the draft hash on its `DRAFT:` line. A failed git command reads `DRAFT: none (draft capture failed: …)`, untracked files named like secrets stay out of the draft, the `DRAFT:` line names the checkout it diffed, and a draft over 100,000 bytes is still inlined, cut there and marked. `run` stays the full run unless `--kind feature` asks for the lean one, `run --kind fix` skips like `next`, and `--kind fix --json` prints one skipped object. `--full` brings back every phase and voice; off Capy and in interactive sessions nothing changes. The gate cost line and the owner brief say a lean `rec` reopens nothing.
+
+## [1.93.35.0] - 2026-11-03
+
+**pregate no longer kills a quiet test suite that is busy working.**
+
+### Fixed
+- **`lib/pregate/supervise.ts`**: the stall timeout now needs both no log output and an idle process group. Each second, supervise reads the group's CPU time (`/proc` on Linux, `ps -S` on macOS and BSDs). If it grew by at least a tenth of the wall time, the group counts as alive. Before, a parallel `check.sh` that printed nothing for 9 minutes while working ended `PREGATE_STALLED` at the 300 s default (Founderstar FOUN-63). A hang that waits on nothing still stalls. A hang that keeps using CPU now runs to `--timeout`, and either way the check is incomplete, never a pass. Windows reads no CPU time and keeps log growth alone. The `PREGATE_STALLED` detail, the guard line and the docs say what was measured. Both new tests fail on main. There a silent CPU-bound command ends `stalled` and a busy lane test ends `PREGATE_STALLED`.
+
 ## [1.93.34.0] - 2026-11-03

 Every Capy thread that uses gstack follows these for new work, under a Captain or on its own. The rule in full is `docs/captain.md`, "Plan before build"; the lane side is section 3 of captain.md in this folder.
 
-- **Plan first.** Before building new functionality, run `/autoplan` on it as the first act after the install check, sized to the work (scope flags and `--max-rounds`; a one-file fix gets `--no-ui --no-dx --max-rounds 1` with `--estimate-usd` and a small `--spend-cap`, never no run).
+- **Plan first.** Run `/autoplan` on new functionality right after the install check. The lean run (the Capy default) is one reviewer over plan and draft code; `--full` adds every phase.
 - **ELI5, then the word.** Send the plan and gate to the person, or the Captain, in plain language: `gstack-owner-brief render --captain --out <run dir> --captain-name "<Captain name>"`, its choices as lettered lines in the ask format (`docs/captain.md`) and "do it" taking every recommendation at full scope. Build only after their word is answered into the run and it reports `APPROVED`; then `gstack-approvals import --autoplan <run dir> --by "<owner>"`.
 - **/ship before ready.** Run /ship at the final pushed head before a PR is called ready; `SHIP_RECEIPT: pr=<n> head=<head>` must name that head, and a later push needs a new /ship. The review inside /ship, like the autoplan, is sized to the change.
 - **Stop a finished /ship subagent.** When a /ship subagent opens its PR, the parent subscribes to that PR with Capy's subscribe tool and keeps that one subscription until the PR merges or closes, re-subscribing if the watch expires, then cancels it. Once the subscription is in place and READY arrives, the parent stops the subagent and owns the PR from then on, slot stamp, re-READY and receipt carry included. A stopped /ship subagent woken by a check, review or merge notice, not by its parent, reports one line naming what woke it, its pin and the PR head (`gh pr view <n> --json headRefOid --jq .headRefOid`) and ends the turn without acting, whether or not the head moved. A message from its parent is an instruction it carries out.
 - **No merge without the owner's word.** A thread never merges on its own; under a Captain the controller merges on a recorded standing approval, and a thread with no Captain asks the person.
 
-Exempt from the plan step: read-only work, the daily flaky pass's repairs, slot stamps, CHANGELOG-only resolves, cap re-pins under a written grant, S1 emergencies (a broken install or upgrade, a red main, a security bug) and fixes from an already-diagnosed, audited problem list.

+- The newest of HEAD's runs (up to 10) under each named profile passes
+  `verifyRun` above: same-repository head (a fork run never counts), the
+  profile's workflow, event and jobs, the newest attempt, no newer red or

+  tree. A `pull_request` run counts only when the pull request already
+  contained its base.
+- Every run executed tests, and with an inventory command, the runs'

+
+**The tests stage.** Without `--from-run`, when the base branch declares
+`run_profiles`, `gstack-pregate` looks up the newest verified run at HEAD under
+the profiles `--from-run` would use and applies it as `--from-run` does: the
+selected local files its `tree.json` lists count as passed, and only the rest
+run. On a small machine a selection the run covers records no remote gate

+same run when the base declares `remote_gate_runs` naming that run's profile:
+the run must pass every `clear --run` check, with the carried files counted
+as selected files. So a remainder of only files the gate's `skipped` command
+names (gstack's paid evals, which the gate itself reports as
+`PREGATE_REMOTE_PAID_ONLY` with `tests=0`) clears with `skipped=<n>` in the
+receipt instead of becoming an obligation nothing can clear. The line is
+`CI_CARRY: cleared pregate.json/remote_gate <receipt>`, or `CI_CARRY:
+pregate.json/remote_gate stays uncleared (<reason>)` when a check refuses, for
+example a gate inventory file missing from the run's `tree.json`.
+
+**gstack's own gate.** gstack's `.gstack/pregate.json` declares
+`remote_gate_runs` with the `ci-reuse/free-tests` profile, so on gstack a green
+Free Tests run at the same tree is how the remote gate obligation clears, and
+the Ubicloud VM (`gstack-pregate --stage tests --remote`) is an opt-in for when
+no such run exists. The order after a push: wait for Free Tests
+(`gstack-ci-carry wait --base main`), then `gstack-pregate
+--allow-repo-commands`. A `pull_request` run tests GitHub's merge commit, so on
+a branch that does not contain the base tip it tested another tree and
+`CI_CARRY` says `none (no_verified_run: … tree_mismatch)`: dispatch Free Tests
+on the branch
+(`gh workflow run free-tests.yml --ref <branch>`), which tests HEAD's own tree,
+and wait again. The preflight stage (generated-file freshness, secrets, strays
+and the other mechanical checks) and the sealed guard are unchanged and always
+run here. The macOS and Windows lane
+obligations still clear with `gstack-pregate clear --remote <lane> --run-url
+<url>` from their CI runs.
+
+**/ship lanes: `ship_lanes_from`.** A lane carries only when the base branch's
+`.gstack/pregate.json` maps its exact command (the evidence ledger binds the
+command's sha256; a label alone never carries) to the profiles whose runs carry
+it and the command that lists its test files:
+
+```json
+"ship_lanes_from": {
+  "bun run test": { "profiles": ["ci-reuse/free-tests"], "inventory": "bun --no-env-file --config=/dev/null run scripts/test-free-shards.ts --list | sed -n 's/^  //p'" }
+}
+```
+
+A carried lane prints `LANE: <label> carried run=<id>/<attempt> tests_ran=<n>`
+and writes an explicit CI-sourced ledger row (`gstack-evidence record-ci
+--label <label> --base <base> -- <command>`, which finds and verifies the run
+itself, so no caller hands it run ids or a test count: `source: "ci"`, its runs
+and profiles, the run's finish time as `ts`, bound to the clean tree), never a
+fictitious local run. `gstack-evidence check` grades it
+like any row and names `source=ci runs=…`, so `finish`'s FRESH check and the
+24-hour age limit apply to the CI run's own time. A mapped lane that cannot
+carry prints `CI_CARRY: none label=<label> (<reason>)` and runs here. Every
+other lane runs through `gstack-evidence run --reuse`: the newest row for its
+label, command and working tree is reused when it passed with a counted run
+under the same runtime (bun and node versions, OS, architecture, runner image)
+within 24 hours; a newer failure on that tree vetoes an older pass, and the
+reused copy keeps the original timestamp. The cache is this machine's ledger
+only; across machines, CI is the trust boundary.
+
+**Finish, push and accept.** `gstack-ship-release finish` commits the release
+metadata, so the stamped tree has no CI run yet. A mapped lane that is not
+already FRESH is deferred (`EVIDENCE: DEFERRED`), and the pregate runs only its
+preflight stage on the stamped tree, written to its own file so the full
+`.gstack/tmp/pregate.json` stays in place until `accept` replaces it. `gstack-ship-release push --early` (the
+Phase 2 push that lets CI run beside the review) runs the secrets scan and the
+sealed guard before it pushes. After the final push,
+`gstack-ship-release accept --base <base> --lane …` waits (bounded by `--wait`)
+for the run at the pushed HEAD, stops on a red or still-running run, carries
+each mapped lane from the green run at that exact tree, reuses or runs the rest,
+checks every lane FRESH and reruns the pregate there, whose tests stage carries
+the same run. `gstack-ship-receipt write` records the carried runs as
+`ci_carried: [{ lane, run, attempt, tree }]`, and the `SHIP_RECEIPT:` line names
+them (`ci_carried=<lane>:<run>/<attempt>`).
+
+**`gstack-ci-carry`.** `find [--profile <name>]… [--command <exact lane command>
+--allow-repo-commands]` prints the verdict for HEAD; `wait [--timeout <s>]`
+polls the newest run at HEAD until it completes (run it in the background) and
+prints `CI_WAIT: green|red|running|none`, then `find`'s verdict on green.

+## Owner-granted flaky exception
+
+A timing flake in a test file the pull request never touched can keep a remote
+gate obligation red: the rerun hits the same 5 s timeout on a loaded runner,
+and nothing in the diff can fix it. `clear --flaky-exception` lets the owner
+accept named cases for one head, on the run's own records:
+
+```bash
+gstack-pregate clear --remote pregate.json/remote_gate --run <id|url> \
+  --flaky-exception "test/docsync-fault-interface-legacy.test.ts::rejects legacy-third" \
+  --pr <n> --allow-repo-commands
+```
+
+The first call checks everything below and then refuses with
+`reason=grant_needed`, printing the exact `gstack-approvals add` command to run
+once the owner says yes: its `--scope` is `flaky-exception:<sha256>`, a digest of
+the repository, PR, head, tree, lane, every run with its attempt, and the sorted
+cases. Record the owner's exact words in that row, then rerun the same clear with
+`--grant <the row id>`. The obligation clears only when all of this holds:
+
+- **Every failure is named from the run's own records.** A red run uploads no
+  `tree.json`, so the clear reads the strict shard runner's artifacts instead
+  (`free-plan`, `free-result-<n>` and `free-test-shard-logs-<n>` in
+  `free-tests.yml`; the `windows-` names in `windows-free-tests.yml`; any other
+  workflow refuses with `no_shard_results`). Every job of the attempt is
+  reconciled: only the shard jobs (`free-suite (<n>)`) and the aggregate that
+  needs them may fail, every job the profile requires must pass, and any other
+  failed or cancelled job refuses (`unnamed_failure`). Every planned shard needs
+  its result; a missing result, a timed-out shard or a missing summary is
+  `shard_incomplete`. A failure the runner could not attribute to a test file,
+  an unhandled error between tests, or a `(fail)` line in a failed shard's log
+  that its result does not record refuses. A retry that passed is a recovered
+  flake; a retry that failed again keeps its own failures.
+- **The cases are exactly the failures.** At most three, written as
+  `<test file>::<test name>` the way the run printed them. A failure no
+  `--flaky-exception` names refuses (`unnamed_failure`), and so does a named
+  case that did not fail (`case_not_failed`). The refusal lists the run's
+  failures in that form.
+- **The files are not the PR's business.** A named file in the PR's diff
+  (`case_in_diff`), or one the import graph reaches from any changed path
+  (`case_in_closure`, lib/pregate/import-graph.ts with the base branch's
+  `dependencies`), refuses. The closure follows imports only: a test that reads a
+  changed doc, template or workflow through the file system is not reached, so
+  required CI stays the check on it. A paid test file (`case_paid`) and a
+  security test (`case_security`: a file name with cso, secrets, gitleaks, sealed,
+  redact or redaction, osv, security, sanitize or inject) are never excepted. Security scans themselves are pregate checks and CI jobs,
+  not test cases, so no exception can reach them.
+- **One head, one grant.** The runs must have tested pregate.json's own head and
+  tree, with no stamp-only substitution (`head_mismatch`); the PR must be open with
+  that head (`pr_mismatch`); no newer run of the workflow may exist on the head
+  (`newer_run`), and the run may not move to another attempt during the check
+  (`run_changed`). The grant row must carry this exception's scope
+  (`grant_mismatch` otherwise), record `approved` (`grant_not_approved`) and be
+  the owner's words, not an agent's (`grant_not_owner`). That last check reads
+  the row's `by` field, which `gstack-approvals add --by` takes as written, so it
+  only catches a row honestly labeled `agent:`. The record is as trustworthy as
+  whoever writes it, the same as every gstack approval. A new head needs a new
+  run and a new grant; a grant is never rebound: `ready` and the ship receipt
+  refuse an exception granted for another PR or head, even when the tree matches.
+
+pregate.json records the grant under `exceptions` (lane, repository, PR, head,
+tree, runs, cases, grant id, who said it, their words and the binding), and the
+obligation's receipt adds `exception=<grant> cases=<n>` to the usual run fields.
+The verdict becomes `pass-with-exception`. `verify` re-checks offline that each
+exception receipt has its entry, bound to this head and tree, with a binding that
+still matches its fields, and prints
+`PREGATE: pass-with-exception (<cases>; grant <id>)`. `gstack-ship-queue ready`
+accepts it and prints one `FLAKY_EXCEPTION:` line per exception in the READY
+block, and `gstack-ship-receipt write` records `flaky_exception` (lane, runs,
+cases, grant, who).
+
+**Pregate only.** The exception clears the pregate obligation and nothing else.
+It never waives a red required CI check: `ready` still needs every required check
+green at the exact head, so a red Free Tests check on the pull request needs its
+own rerun to pass. Changing that contract is a separate decision for the owner.
+
+**Why not `base_red`.** `base_red` (docs/ship-policy.md#base-red) proves a
+failure belongs to the base by reproducing it there, at the base head and at the
+PR head. A timing flake usually passes on the base (the 2026-11-02 docsync case
+passed in 3.5 s on main and failed at 5 s on the PR's tree), so `base_red`
+returns `IN_BRANCH` and refuses. The exception path asks a different question:
+not "is the base broken?" but "is every failure named, outside this PR, and
+accepted by the owner?"

A base line whose text duplicates a line the branch added gets the branch's bound too, because the checks match branch lines by text, not position (GST-979).

+# Skill routing and skill contracts
+
+Two opt-in Claude Code hooks that help a model actually run gstack's skills (GST-1088). Both are **off by default**, and with both off nothing changes.
+
+- **Skill routing** (`skill_routing`, a UserPromptSubmit hook). When a prompt matches an installed skill's `triggers:`, the hook adds one line of context naming that skill, for example "this request fits /investigate. Run /investigate with the Skill tool before you start".
+- **Skill contracts** (`skill_contracts`, a Stop hook). A skill can declare the outputs that must exist before it is done. When the model tries to stop without them, the hook blocks once and names what is missing.
+
+## Turn them on or off
+
+Each switch resolves in this order, and the first one set wins:
+
+1. The `./setup` flag: `--skill-routing` / `--no-skill-routing` and `--skill-contracts` / `--no-skill-contracts` (also `--skill-routing=on|off`). A flag is saved to config, so it survives upgrades.
+2. The environment: `GSTACK_SKILL_ROUTING` and `GSTACK_SKILL_CONTRACTS` (`on` or `off`). Not saved.
+3. Config: `gstack-config set skill_routing on|off` and `gstack-config set skill_contracts on|off`.
+4. The default: off.
+
+`on` also accepts yes, true and 1; `off` accepts no, false and 0. Setup warns about any other value, uses off for that run, and does not save it.
+
+Setup registers a hook only when its switch is on, prints one line the first time it registers it, and removes the registration when the switch is off (or with `--no-team`). The hooks also read the switch every time they run, so this takes effect on the next prompt without re-running setup:
+
+    gstack-config set skill_contracts off
+    gstack-config set skill_routing off
+
+The off switch is for people. The text the Stop hook shows the model never mentions it.
+
+## Host support
+
+| Host | Routing hook | Contract Stop hook | Notes |
+|---|---|---|---|
+| Claude Code | yes | yes | Registered in `~/.claude/settings.json` by `./setup` |
+| Codex, OpenCode, Cursor and other hosts | no | no | No hook support. `gstack-skill-contract check` still works on a Claude Code transcript |
+
+## Routing
+
+The hook scores the prompt against the `triggers:` list in each installed `SKILL.md` (`~/.claude/skills/*/SKILL.md`, or `$CLAUDE_CONFIG_DIR/skills`). It makes no model call and no network request, and the same prompt always gets the same answer.
+
+- A trigger scores 1 when its whole phrase appears in the prompt. Otherwise it scores the share of its content words (common words dropped, light stemming, so "failing" matches "fails") that the prompt contains. A trigger with one content word counts only on its whole phrase, unless that word has five or more letters and is not a question word.
+- Only /investigate, /review, /qa and /verify route. In the d7 check (PR #3912), scoring every installed skill's triggers sent 17 of 32 non-fit Terminal-Bench prompts to some skill at 0.66; routing only these four sends 4. The other skills wait for their own trigger review.
+- The skill with the best score routes when it reaches the threshold, 0.66: both words of a two-word trigger, or two of three.
+- Prompts that start with `/` (you already picked a skill) and prompts over 8,000 characters (pasted logs) are never routed.
+- The injected line names its source and its off switch, and asks the model to tell you in one sentence that gstack routed the request.
+
+### Dry run
+
+`gstack-skill-route --explain` shows what the hook would do, with the switch on or off. It never injects anything.
+
+    $ gstack-skill-route --explain "this test fails, fix it"
+    switch: skill_routing off (default)
+    threshold: 0.66
+    skills: 65 scanned in /home/you/.claude/skills
+    candidates:
+      1.00  /investigate  "fix this bug" (2 words)
+      0.67  /ios-fix  "fix this ios bug" (2 words)
+    route: /investigate
+    hint: gstack skill routing (UserPromptSubmit hook; ...
+
+Add `--json` for a machine-readable answer, or `--threshold <n>` to see another cutoff. `GSTACK_SKILL_ROUTE_HINT=name|step|contract` picks the hint wording the d6 pilot compares: the skill name only (default), plus the skill's first step, or plus its contract.
+
+### Routing log
+
+Every decision is one line in `$GSTACK_STATE_ROOT/hooks/skill-route.log`: the session, the event (`routed`, `no-route` with its reason, or an error) and, for errors, `failures=<n>` for that session. The log never holds prompt text. On any error the hook prints nothing and exits 0; it never blocks a prompt.
+
+## Contracts
+
+### Schema (version 1)
+
+A skill declares its contract in its `SKILL.md` frontmatter:
+
+    contract: { version: 1, items: [ { id, kind, ... } ] }
+
+Every item has an `id` (lowercase letters, digits, `.`, `_`, `-`) and a `kind`, plus optional `fix` (the action the block text names) and `summary` (the phrase the routing hint's contract variant uses). At most 20 items.
+
+| kind | Fields | Met when |
+|---|---|---|
+| `report_labels` | `heading`, `labels[]` | The last assistant message containing the heading has a `Label: value` line for every label, and no value is empty or a placeholder (`[...]`, `<...>`, TBD, TODO, `...`, or a template like `DONE \| BLOCKED`) |
+| `check_after_last_edit` | optional `match` (regular expression) | No Edit, Write, MultiEdit or NotebookEdit happened, or a Bash test or repro command ran after the last one. By default a command counts when, with quoted text removed, one of its parts (split on `&&`, `\|\|`, `;`, `\|`) starts with a test runner, build tool or interpreter (bun, npm, pytest, go, cargo, make, node, python, curl, ...) or a script whose name says test, spec, repro, check, verify or lint, directly or behind a wrapper (`bundle exec rspec`, `uv run pytest`, `docker compose run app pytest`, `xvfb-run npm test`, `bash scripts/test.sh`). `git commit --no-verify`, `cat test/a.test.ts` and the shell's `test -f` do not count |
+| `selected_specialists_dispatched` | optional `marker`, `empty_marker` | The selection line was printed in an assistant message or a Bash result (never a fetched page or file), its names are plain (letters, digits, spaces, `_`, `.`, `-`, at most 40 characters), and each specialist it names has an Agent dispatch that mentions it. The marker is literal text in which a whole-word N stands for a number; the default is `Dispatching N specialists:`. N = 0 (`Dispatching 0 specialists: (small diff)`) or a "specialists skipped" line means zero specialists were selected, which passes. Text in parentheses is not a name (`Dispatching 1 specialists: State Machines (small diff)` selects State Machines) |
+| `agent_dispatch` | `match` (regular expression, case-insensitive), optional `marker` | The `marker` line (literal text, like /review's `Dispatching adversarial pass: native`) was printed and an Agent dispatch follows it; otherwise, as the fallback, an Agent dispatch's description or prompt matches `match` |
+
+A run the skill ended early counts as met: a final `STATUS: BLOCKED` (for /investigate, `Status: BLOCKED` in its DEBUG REPORT) or a final message with a line that starts "Nothing to review" (/review's early exit).
+
+The checker's default marker strings live in one table, `DEFAULT_MATCHERS` in `lib/skill-contract.ts`; a skill's own `marker`, `empty_marker` or `match` overrides them.
+
+Items are checked against one run of the skill: from its last load to the end of the session, or to its next load when `report` re-checks an earlier run. A load is a Skill tool call, a typed `/name` command, or a Read of its `SKILL.md` under a `skills/` directory (reading the source in a gstack checkout is not a load). A run recorded `met`, `met_waived` or `met_after_block` stays that way, so a later unrelated turn in the same session is never blocked by it.
+
+### Worked example
+
+    contract:
+      version: 1
+      items:
+        - id: debug-report
+          kind: report_labels
+          heading: DEBUG REPORT
+          labels: [Symptom, Root cause, Fix, Evidence]
+        - id: repro-after-fix
+          kind: check_after_last_edit
+
+A session loads /investigate, edits `src/auth.ts` and answers "Fixed: the null check was missing." with no report and no test run. The Stop hook blocks once with:
+
+    SKILL_CONTRACT_UNMET investigate (contract v1): missing debug-report, repro-after-fix. Fix: debug-report: print the DEBUG REPORT with real values for Symptom, Root cause, Fix, Evidence; repro-after-fix: run the test or repro again after your last edit and show its result. If an item truly does not apply, run gstack-skill-contract waive <item> --reason "<why>" (this session only; counted as a miss for follow). This blocks once.
+
+The model runs `bun test`, prints the DEBUG REPORT, and stops. The record reads `met_after_block`.
+
+### When the Stop hook checks
+
+The hook checks the most recently loaded skill that declares a contract, and only when the turn is a final one:
+
+- the last assistant message has a STATUS line (`STATUS: DONE`, `Status: DONE_WITH_CONCERNS`, `**Status:** BLOCKED` and the like), or
+- the session is headless or unattended (`gstack-session-kind`), or
+- the turn does not end on a question to the user (a last paragraph ending in "?", an AskUserQuestion call, or `NEEDS_CONTEXT`).
+
+So an interactive session that pauses to ask a question is never blocked. When Claude Code says a Stop hook already continued this turn (`stop_hook_active`), the hook never blocks: after its own block it records the result (`met_after_block` or `miss`). It also allows the stop while Agent dispatches are still running (no result yet, or launched in the background with no completion notice naming that agent), because their outputs may still arrive. Because Claude Code can fire Stop before the turn's last message reaches the transcript file, the hook reads the payload's `last_assistant_message` as the turn's final text.
+
+It blocks at most once per skill run. If the model stops again with the contract still unmet, the stop is allowed and the run is recorded as a miss.
+
+### Records
+
+Each Claude Code session has one record, `$GSTACK_STATE_ROOT/skill-contracts/<session id>.json`, written atomically (mode 0600) before any block. Each skill run in it has an outcome: `met`, `met_waived`, `blocked`, `met_after_block` or `miss`. The hook's decisions also go to `$GSTACK_STATE_ROOT/hooks/skill-contract.log`.
+
+## Commands
+
+### check
+
+    gstack-skill-contract check --transcript <path> --skill <name> [--skill-file <SKILL.md>] [--json]
+
+A pure function of a Claude Code transcript (the JSONL a hook payload's `transcript_path` names, under `~/.claude/projects/`). The contract comes from the installed skill's frontmatter, or from `--skill-file`. It prints each item as met, missing or waived. The model never records anything itself, so evals can run the same check on their own transcripts.
+
+### report
+
+    gstack-skill-contract report [--json] [--session <id>]
+
+Lists misses by skill and item, then each missed run. A miss is a run that was blocked and never fixed, stopped again unmet, or met only through a waiver. A run still marked `blocked` is re-checked against its transcript when the file is still there, so a run fixed after its block reads `fixed_after_block`, not a miss.
+
+### waive
+
+    gstack-skill-contract waive <item> --reason "<why>" [--skill <name>]
+
+The escape for an item that truly does not apply (a docs-only change has nothing to test). It is stateless: it checks its arguments and prints an acknowledgement. `check` finds the waiver by reading this Bash call in the transcript, for this session only, and a waived item still counts as a miss for follow. A waive call that failed, has no reason, or names another skill does not count.
+
+## Exit codes and errors
+
+`gstack-skill-contract` exit codes are stable.
+
+<a id="exit-0-met"></a>
+### 0: met (SKILL_CONTRACT_MET)
+
+`check`: every item is met or waived. `report` and `waive`: done.
+
+<a id="exit-1-unmet"></a>
+### 1: unmet (SKILL_CONTRACT_UNMET)
+
+At least one item is missing. Text output starts with the same line the Stop hook would block with. Do what each item's Fix says, or waive an item that does not apply.
+
+<a id="exit-2-usage"></a>
+### 2: usage (SKILL_CONTRACT_USAGE)
+
+A missing or malformed argument: `check` without `--transcript` and `--skill`, `waive` without an item id or `--reason`, or an item the named skill's contract does not have. `gstack-skill-route` uses 2 the same way (SKILL_ROUTE_USAGE).
+
+<a id="state-error"></a>
+<a id="exit-3-state-error"></a>
+### 3: state error (SKILL_CONTRACT_STATE_ERROR)
+
+A file could not be read or written: the transcript is missing or over 32 MiB, the session record is corrupt, or the state root is not writable. The Stop hook fails open on these and prints one stderr line:
+
+    gstack-skill-contract: SKILL_CONTRACT_STATE_ERROR <path>: <cause>; stop allowed, miss not recorded (see docs/skill-routing-and-contracts.md#state-error)
+
+The stop goes through and nothing is recorded. Fix the named path: make `$GSTACK_STATE_ROOT` writable, or delete a corrupt `skill-contracts/<session>.json` (it only holds this session's outcomes). An invalid contract block in a skill's frontmatter is reported the same way, naming that `SKILL.md`. A hook that runs past its 5 second deadline also fails open here.
+
+<a id="exit-4-unknown-shape"></a>
+### 4: unknown transcript shape (SKILL_CONTRACT_UNKNOWN_SHAPE)
+
+The file is not a Claude Code transcript this checker understands (no user or assistant records, or message content that is neither text nor a block list), for example after a Claude Code format change. The Stop hook fails open with a state error line and adds one to `$GSTACK_STATE_ROOT/hooks/skill-contract.canary.json`. A rising canary count means the parser needs an update.
+
+<a id="exit-5-no-contract"></a>
+### 5: no contract (SKILL_CONTRACT_NO_CONTRACT)
+
+No installed skill has that name, its `SKILL.md` declares no contract, or the contract block is invalid (the message names the problem, such as an unsupported version or an unknown kind).
+
+<a id="exit-6-not-loaded"></a>
+### 6: not loaded (SKILL_CONTRACT_NOT_LOADED)
+
+The transcript never loads the skill, so there is nothing to check.

+  `status: "skipped"`). `run --kind fix` does the same before any paid call.
+  An `--out` that already holds a run is refused. The PR still owes the bug's
+  proof: a repro on current main or a failing test written first.
+- **`--kind feature`**, the default for an unattended run on Capy
+  (`GSTACK_CAPY=1`) that names no kind, is the lean run. The run is the `eng`
+  phase alone with one native reviewer, whose prompt merges the CEO and Eng
+  lenses (Design and DX only when scope detects them) and always asks "Any
+  outside terms, licences or rights involved?". The reviewer reads the draft
+  code with the plan: `git diff` from the merge base with `--base <ref>`
+  (default `origin/HEAD`), untracked files included and the run directory
+  left out, written into the phase's snapshot directory as `draft.diff` and
+  hashed into `run.json` (`phases.eng.draft`) and the `phase_opened` journal
+  row. With no code yet, the run says so: `DRAFT: none (<why>)`. A git
+  command that fails is `DRAFT: none (draft capture failed: …)`, never a
+  partial draft. The draft goes to a model provider, so a file whose name
+  looks like a secret (the whole `.env*` family, `.envrc` included, `*.pem`,
+  `*.key`, `*.p12`, `id_rsa` and the other SSH private keys, `.netrc`,
+  `.npmrc`, `.pgpass`, `*credentials*`, `*secret*`) is never read, tracked or
+  untracked, and is left out with a note; so is either side of a rename or
+  copy git detects in the branch's commits or staged changes. A secret moved
+  without `git add`, copied unchanged, or renamed and heavily edited reaches
+  the draft under its new name, guarded only by the content check. Every other file's patch goes
+  through the redact engine (`lib/redact-engine.ts`), so a key in an ordinary
+  file reaches the reviewer as `<REDACTED-…>`; a patch it can't redact safely
+  is left out with a note. The `DRAFT:` line names the checkout it diffed (`root=`). The prompt inlines the diff in a fence longer than any tilde
+  run inside it, cut at 100,000 bytes (`shown=` on the `DRAFT:` line) with a
+  note asking the reviewer to name what it didn't see. The reviewer's
+  line after INPUT names the draft (`DRAFT: <sha256>` or `DRAFT: none`), or
+  submit refuses the result with `RESULT_RECEIPT_MISSING`. A hand-run record
+  bound with `--attest` has no receipt at all, so its deviation says the
+  draft was not bound. `run`, which pays for both voices, stays the full run
+  unless `--kind feature` asks for the lean one. There is no outside
+  voice, `--max-rounds` defaults to 1, carry-forward is off, and the gate has
+  one revision: `revise --incorporates` applies the owner's accepted changes
+  without re-review (`APPLIED: … (lean run: one gate revision; …)`) and
+  approves. The gate and `gstack-owner-brief render --captain` relay work as
+  in the full run. A paid-eval prereg counts as a feature.

+ *   event and jobs, the newest attempt, no newer red or running run on HEAD,
+ *   max age, the run's own tree.json naming HEAD's tree);
+ *   every run executed tests;
+ *   with an inventory command, the runs' tree.json files cover every file it
+ *   prints (a lane carries only what CI provably ran);
+ *   every run still stands after the inventory ran (runChanged).

+ * the runs only when:

+ *   timed-out or unattributed shard is incomplete evidence), and each failed shard's log names no failure its result
+ *   omits;
+ * - the named cases are exactly the failures, at most three, none in a paid test file or a test of a security scan,
+ *   and each file is outside the PR's diff and the diff's import closure (lib/pregate/import-graph.ts);
+ * - the runs tested pregate.json's own head and tree (no stamp-only substitution), the PR's head is that head, and an
+ *   approved gstack-approvals row in the owner's words carries the scope `exceptionBinding` computes over repository,
+ *   PR, head, tree, lane, runs with their attempts and cases, so it cannot be rebound to another head or case list.

+ * It is pregate only: nothing here touches a required CI check, which still needs its own green run at the head.
+ * base_red is not used: it proves a failure by reproducing it on the base, and a timing flake passes there.

The fixed code at lib/ship-receipt-depth.ts:153 refuses on either one. So a user who hits the refusal after a docs-only or TODOS.md commit (the Step 14 and 14.5 commits) finds no matching cause in this entry. docs/review-policy.md and the changelog fragment were updated; this entry was not."}
+{"severity":"INFORMATIONAL","path":"lib/ship-receipt-depth.ts","line":153,"summary":"The fix list calls this main's rule, but it isn't. On origin/main, parseReviewTargeted(value, productPatchId) takes no head and binds any record. So under this change, every money, gate, auth or secret ship whose Step 14 or 14.5 commits after the Step 11 read now stops at Step 19 with RECEIPT_INVALID. That is the same outcome pass 1's Red Team flagged. Step 19's prose (ship/sections/pr-body.md:247, 'fix that input file and rerun') doesn't say to rerun the targeted reader on HEAD; only the tool's own error message does. The guard fails closed, and the code deliberately defers the docs-only case to GST-1031, so this is not data loss. It is a known extra stop in unattended /ship runs."}
+{"severity":"INFORMATIONAL","path":"lib/ship-receipt-depth.ts","line":153,"summary":"When the product patches are equal and only classesSince refuses (a test edit after the read that skips a case), the message prints the same patch id twice: 'whose product patch X is not this receipt's X'. This was already true before the fix and the fix kept it. The message misstates the cause; the decision itself is correct."}
+
+I found nothing at the blocking floor. The OR guard fails closed in the right places: it refuses when the product patch differs, when classesSince returns null (unreadable), and when a class shows up after the read. Its only production caller, bin/gstack-ship-receipt:227, passes the same arguments as before. The test change does replace the old docs-binds assertion with a refusal, but that matches the intended new rule; it doesn't weaken coverage. The new no-money-token regression test covers the CRITICAL fix. I reran the three focused files at this tree: 34 pass, 0 fail, 403 expect() calls.

+I reviewed the range base..HEAD, one commit that changes four files. I read every non-test file in full.
+
+## Findings
+
+**1. The family check refuses two models in one call even when no task is judged (check.ts:165-169). FIXABLE.**
+The family check runs whether or not the run uses a judge. Elsewhere the judge is used only when `judged` is true.
+
+Before this commit the call passed. Now every judge stops with E_POLICY:
+- the default judge clashes with the second model;
+- the other judges clash with the first model.
+
+So the two models can no longer run in one call, even though the judge would never be called. It fails closed with a clear message, and two calls work around it.
+Fix: `else if (judged && sameFamily.length)`, plus a test with an unjudged set.
+Severity: Medium. Blocks: no.
+
+**2. max_price now uses the long-prompt rates for every call, short prompts included (prices.ts:75, set at proxy.ts:513). FIXABLE, with part to INVESTIGATE.**
+`routing` sets max_price from the price row alone, whatever the prompt length.
+
+Today the only endpoints are standard, fast and ultrafast.
+
+Two more problems:
+- The commit assumes the router checks max_price against long-tier rates.
+- The new doc comment gives the wrong reason.
+
+Fix: build max_price per request.
+Severity: Low. Blocks: no.
+
+**3. The docs' third-family judge barely exists (docs/eval.md:125, policy.ts:125-129). INVESTIGATE.**
+Only weak judges have price rows, so in practice the remedy is two calls.
+
+Also, call.ts still picks the default judge by provider, not by family.
+Severity: Low. Blocks: no.
+
+Recommendation: Fix the unconditional family check at check.ts:169, because gating it on `judged` is a one-line change.

+ *   1. windows-smoke.yml stays the unfiltered Windows check on every pull
+ *      request.
+ *   2. windows-setup-e2e.yml starts only on install paths, and its
+ *      windows-scope job keeps the two Windows jobs off a pull request whose
+ *      only install change is package.json's version line (the merge-train
+ *      stamp).
+ *   3. windows-scoped-tests.yml runs the changed Windows-safe test files when
+ *      a pull request touches path, file-name or process code. Its filter must
+ *      catch #3758 (/freeze's check-freeze.sh, a hook path) and #3829 (a test
+ *      that spawned Bun with --config=/dev/null), and pass over a docs-only
+ *      and a pure-logic change. Its aggregate passes when nothing is in scope,
+ *      so a skipped run still reports success.
+ *
+ * The filter and scope steps run here as the runner would run them: bash in a
+ * two-commit git repository, with HEAD^1 as the pull request's base.
