feat(cli): make the silent hook-body downgrade loud — os lint refuses an accidental scope leak (ask 1)

[os-steve]

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run.

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run.

Which tree this was computed on

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

Of those 172: 14 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 56 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 102 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run.

Which tree this was computed on

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

Which tree this was computed on

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run.

Which tree this was computed on

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

📓 Docs Drift Check

This PR changes 1 package(s): @objectstack/cli, touching 20 documentable anchor(s).

20 hand-written doc(s) name something this change touched — list omitted above 15 rows. Re-derive on the tree named below: node scripts/docs-audit/affected-docs.mjs --json 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3.

⛔ 4 release-owned page(s) also affected — read-only, see AGENTS.md Documentation Guardrails.

What this run could not see

• 7 name(s) were too generic to anchor anything (single lowercase words)
• the SDK route bridge reached 47 of 219 client-bound route-ledger rows — the other 172 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 172: 14 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 56 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 102 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.

Coarse fallback — 23 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3 → packageMentionDocs.

Which tree this was computed on

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin eaafd10ea0286503974721290172055cee499e6d && git checkout eaafd10ea0286503974721290172055cee499e6d

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.

Fixes#13651

Scope is ask 1 only (fail loudly). The constant-surface half is #13718 and is not addressed here — no half of it is stubbed in, out of scope: #13718 remains open.

Clause-②: yes

This changes what os lint rejects: a config whose hook handler leaks module scope now produces a lint error, so os lint exits 1 where it previously exited 0.

It does not change what os build accepts. That was a deliberate choice, not an omission — see the measurement below. The catch in lowerCallables stays, both refusal classes still fall back to bundling, and the build still exits 0; the three e2e suites that spawn a real os build pass unchanged.

PR stays draft. Not armed, not queued, not flipped ready.

The measured population — the reading #13718 needs to size itself

Measured on the real build path, not by re-implementing it: loadConfig (bundle-require/esbuild, exactly what os build uses) then normalizeStackInput then lowerCallables, reading the reason strings the real extractHookBody produced.

config	callables lowered	body extracted	on the silent-downgrade path
objectstack-ai/hotcrm (the reference app, aff9cb2f)	39	39	0
examples/app-showcase	2	0	0
examples/app-todo	2	1	0
examples/app-crm	1	1	0
plugin-auth, plugin-security, service-i18n	0	0	0
create-objectstack blank template	0	0	0 (declares no hooks or functions)
total	44	41	0

The existing population on the silent-downgrade path is zero. Nothing in this repo or in the reference app currently takes it.

Two things that number does not mean:

1. It is not evidence the gap is cheap. The reference app reads zero because it already paid — all 39 of its callables are written defensively, with constants hand-copied into each handler and eight bespoke pin tests whose only job is to notice when the copies drift. That is the cost Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651 documents, and it is what Give a lowered hook body a declared constant surface — every shared constant is currently hand-copied into each handler and pinned by a bespoke drift test (8 rows in the reference app) #13718 is sizing.
2. It is not a licence to break os build. Zero here says nothing about apps outside this tree, and os build is a published CLI.

The 3 callables that produced no body and no warning are not this class: they are top-level functions: map entries (app-showcase 2, app-todo 1), a path that never attempts extraction by design.

Positive control (a zero-hit is not a reading without one). The same instrument over a fixture with three known-outcome hooks reported exactly: hook_free to free-identifiers, hook_forbidden to forbidden-token, hook_clean extracted. The instrument yields positives in both classes, so its zeros are real.

Which gate shape, and why

The card offered two. Chosen: the lint diagnostic a gate can fail on — the card's own steadier intermediate — made class-aware.

Against making os build fail outright: the population is zero, so that option reddens nothing today, but it changes the accept set of a published CLI for apps that cannot be measured from here, and it would take the legitimate fallback down with the accidental case. compile.ts step 2c already records that position in-tree.

Why os lint's own rubric rather than the shared authoring-rule registry: the registry's gating tier must be run by all three commands (so it would move the build's accept set), and its advisory tier can never emit an error. lintConfig is the only tier whose error fails os lint alone — its own comment calls it "a lint verdict, not a publish gate".

Telling an author's mistake from a deliberate bundle

The refusal already knew which rule refused; the throw flattened it into prose and the catch kept only the sentence. It now carries kind:

• accidental (free-identifiers) — the handler is expressible as a metadata body; it merely names a module-scope const, helper or import. The deployment shape changed against what the author wrote. Gives a error, rule hook-body/not-lowerable.
• structural (forbidden-token) — fetch/require/process/eval are capabilities the sandbox does not have, so writing one is choosing a bundled closure and the bundle is the designed answer. Gives a warning, rule hook-body/bundled-fallback.
• unparseable gives a warning. unknown (a non-HookBodyExtractionError throw) is kept distinct from unparseable on purpose: an instrument failure must not read as a verdict about the author.

An author who deliberately wants a bundled closure keeps two channels that already existed, are already honoured, and stay silent — neither needs a new spec key: give the hook an explicit body, or move the function into the top-level functions: map and reference it by name. So the inline-function form means "I intend this to be a hook body" and the named-functions: form means "I intend this to be bundled code" — a distinction the authoring surface already had and nothing was reading.

Parity by construction: the rule calls the sameextractHookBody the build calls, so the lint verdict cannot drift from what the build would do to the same handler. Pinned by a test that asserts the two see exactly the same callables.

Ablation

Direction predicted in writing before running: mutating the kind === 'free-identifiers' branch so the rule stops consulting the classification should turn the accidental class into a warning, reddening the error-severity and parity pins, while the refusal-kind suite stays green.

Observed: mutation proven on disk (blob b47714f4 to f71b0286, anchor count 1 to 0, injected 0 to 1); 3 tests failed in hook-body-lowering.test.ts — the two predicted plus the action-path pin, which is the same accidental-class assertion applied to actions, so wider in extent than predicted, same direction; hook-body-refusal-kind.test.ts stayed green as predicted. Restore proven three ways: blob hash equal to the HEAD blob, empty git diff HEAD, clean git status --porcelain.

No rebuild leg was needed, and the ablation itself is the proof: mutating src/ changed the outcome with no build, so these tests read source, not dist.

Verification

Gate union derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after merging origin/main and after the last edit, harvested with --commands (never grepped), each exit code captured before any pipe.

union named 36, ran 36, unreconciled 0

comm -23 and comm -13 are both empty (exact comparison, no arithmetic on a hand-kept counter). 35 path-derived plus convention-triggered families, plus pnpm lint, which the derivation never names.

• pnpm lint (eslint . --no-inline-config): run repo-wide, exit 0. No narrowing to declare.
• pnpm --filter @objectstack/cli typecheck: exit 0.
• Tests: 12 files, 171 tests passed, including the three e2e suites that spawn a real os build.
• All runs above are on 59e77df0d7.

Two families exited non-zero during the sweep; both are resolved:

• node scripts/check-test-completeness.mjs — exit 3, NOT MEASURED, in the gate's own words: "PREREQUISITE NOT MET — this gate grades a saved turbo run test log, and no log was named. … the local reading for this gate is NOT MEASURED. It is not a red, and there is nothing here to fix."
• pnpm check:type-check-debt — exit 1, a real red that is fixed at source. TEST_DEBT['@objectstack/cli'] recorded 144, tsc --noEmit reported 147 (+3). packages/cli/tsconfig.json says include: ["src"], so the two new test files sit inside the package program and carried 3 TS7053. Attributed mechanically: removing exactly those two files returned the ledger to green with no other entry moving, so the +3 was entirely theirs. Fixed by typing the two fixture maps. The entry was not raised — shrink-only and maintainer-only by the gate's own text. Re-run on the merged head: exit 0, "29 ledger entr(ies) re-measured … none above its recorded number."

Changeset

@objectstack/cli: minor. What this publishes rides on two CLI surfaces, not on new API exports — corrected in the contract-review patch round: HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-internal (the package exports map exposes only . and ./console, and src/index.ts re-exports none of them). The published carriers are the os lint exit contract (a new error rule, so os lint can newly exit 1 where it exited 0) and the kind / freeIdentifiers fields on os build --json's bodyExtractionWarnings. Nothing removed, os build's accept set untouched, so not major. Precedent: the launch-window narrowing-as-minor convention stated in .changeset/form-view-option-default-narrowed.md; the earlier citation (cli-i18n-flow-screen-bucket) is not on point — its diagnostics error only under --i18n-strict.

Patch round — at-tier contract review (2026-09-01, head f46ff14252)

Acting on the REQUEST CHANGES review (items 1 and 2; item 3 — the verbatim Clause-②: yes line on the #13651 claim comment — is the PM seat's, not addressed here). Both premises re-derived against the tree before editing: packages/cli/src/index.ts names none of the three types (grep exit 1, no export *), the package exports map is . and ./console only; and judge()'s catch branched only on free-identifiers, so unparseable/unknown fell into the bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide."

1. Changeset corrected (.changeset/cli-hook-body-lowering-loud.md): the "new exports" sentence is replaced by the real published carriers — the os lint exit contract (0 → 1) and the kind/freeIdentifiers fields on os build --json's bodyExtractionWarnings. Grade unchanged: minor.
2. judge() keeps instrument failures distinct from author verdicts: unparseable and unknown no longer borrow the bundled-fallback prose; they report under their own rules — hook-body/unparseable and hook-body/extraction-failed — as warnings whose prose says "not a verdict about the handler". Severities unchanged (warning), so this patch moves no exit contract. The parity pin's rule→kind map is now total over all four kinds and its fixture population includes both instrument kinds, so build and lint are pinned to label them identically; three unit pins additionally forbid the instrument kinds from ever reading as a chosen bundle.
   • Ablation (direction predicted in writing before running): excising the new instrument arm restores the fold and should red exactly 4 pins — the two new unit pins, the distinctness pin, and the extended parity pin — leaving the other 9 in the file green. Observed: exactly those 4 failed, on the rule-identity assertions. Mutation proven on disk (blob 009c3960 → d0b07871, unique anchor "the extraction instrument itself failed" count 1 → 0); restore proven (blob hash equal, empty git diff HEAD, clean git status --porcelain); trap in the same process as the measurement.

Verification on the merged head f46ff14252: gate union re-derived post-merge (the pre-merge derivation self-reported STALE TREE), named 36 (35 derived + pnpm lint, which the derivation never names), ran 36, unreconciled 0 — comm -23 and comm -13 both empty, exact string comparison, every exit code captured before any pipe. 31 gates green first pass; 4 families (check:dual-build-cjs-loads, check:i18n, check:i18n-coverage, check:type-check-debt) first reported PREREQUISITE NOT MET (no built dist/ — NOT MEASURED, not treated as pass or red), so the closure was built exactly as each gate's text instructs (turbo run build --filter='./packages/*' --filter='./packages/*/*', 70/70) and all 4 re-ran exit 0, measured — type-check-debt: "29 ledger entr(ies) re-measured … none above its recorded number" (the new pins add zero debt; the ledger was not touched). check-test-completeness exit 3 stays NOT MEASURED in the gate's own words ("this gate grades a saved turbo run test log … running the family locally, record this gate as NOT MEASURED"); the in-lieu reading: full @objectstack/cli vitest suite on the built closure — 223 files, 2553 tests, 0 failures, exit 0. PR stays draft; labels untouched.

This run read content/docs from eaafd10ea0286503974721290172055cee499e6d — the merge of head f46ff142523b010756a6add78e249bfe9dc22b7e into base 3b2a3f640c7ed41a5c4851b9f3bf24b7c42158f3, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes

Contract review (Clause ②) — REWORK

Reviewed at head 59e77df0d7853ec6bda10ec49a5d85c231b793ed, still the head. Rendered by a CONTRACT_REVIEW_TIER reviewer in an isolated context; transcript tier-verified before adoption (85 harness-stamped assistant turns, 100% at tier, first and last included, service_tier: standard throughout, zero fallback evidence). The triage seat runs below tier and therefore adopts verbatim or voids whole. Adopted verbatim, unedited:

VERDICT: REWORK
CLAUSE-2-PATH: no
CLAUSE-2-CONTENT: yes
DECLARATION-HONEST: yes
ONE-LINE: Clause-② content limb is real and honestly declared — os lint's accept set narrows (exit 0→1 on an accidental scope leak) while os build's accept set is provably untouched and no in-repo corpus trips the new error — but the machine spelling `Clause-②: yes` exists only in the PR body, not in the claim comment where the enqueue gate's declaration limb reads it, so the record must be completed (plus two wording fixes) before ready.
FINDINGS:
- Machine declaration missing at the gate's reading site: SKILL.md's claim template makes `Clause-②: yes|no` a mandatory claim-comment field and the enqueue gate's declaration limb reads "认领评论声明 `Clause-②: yes`"; the claim comment on #13651 carries no `Clause-②:` line at all — the verbatim spelling appears only in the PR body, leaving the declaration limb unbound (fail-open, the very pattern this PR fixes). Required fix: add the verbatim line to the claim comment.
- CLAUSE-2-CONTENT yes rests on two facts verified in source: `os lint` exits `errors.length > 0 ? 1 : 0` and the new rule emits severity `error` for kind `free-identifiers`; and `os build --json` publishes `bodyExtractionWarnings` (compile.ts), which now carry `kind`/`freeIdentifiers`. The negative boundary (2026-08-28 ruling) does not apply — this is a published CLI contract surface, not a runtime permission behaviour.
- In-repo corpus verified NOT to trip the new refusal by direct reading, not assumption: app-crm and app-todo handlers reference only `ctx` plus `Date`/`Error`/`String` (all in `detect-free-identifiers.ts` GLOBALS); app-showcase hooks carry explicit `body:` (skipped via `if (!hook.body)`); `functions:` map entries are never extracted. All 35 CI check runs green on head 59e77df0d7. The hotcrm zero is the PR's own positive-controlled measurement — external repo, not independently re-run here.
- Changeset overstates the public-surface widening: "new exports (`HookBodyExtractionError`, `HookBodyRefusalKind`, `BodyExtractionWarning`)" are module-level only — the package `exports` map exposes just `.` and `./console`, and `src/index.ts` on the PR head re-exports none of them; the real published carriers are the lint exit contract and the `--json` field. Grade unaffected, wording should be corrected.
- Nearest precedent mis-cited: `cli-i18n-flow-screen-bucket` (verified real, minor) gains diagnostics that error only under `--i18n-strict`, while this rule errors by default; the closer in-tree precedent is the launch-window breaking-narrowing-as-minor convention stated verbatim in `.changeset/form-view-option-default-narrowed.md`, which the changeset (labelled "Additive") does not name. Minor is correct under either route.
- Lint-surface `unknown` handling contradicts the PR's own claim: `judge()` folds a non-`HookBodyExtractionError` throw into `hook-body/bundled-fallback` with the "This is the designed fallback" message — reading an instrument failure as a verdict about the author, exactly what the PR says is "kept distinct on purpose" (honoured only in `lowerCallables`' warnings); the parity test's rule→kind map also has no row for `unknown`, so build and lint would label such a callable differently. Edge path (extractor bug required), one-line fix.
- Honoured disciplines confirmed: #6479's ruling that a new rejection on a shipped surface must be escalated, not substituted (rejection lands on lint only, declared, drafted, parked for the maintainer's ruling on this third clause-② class); pins falsifiable in both directions (error-on-leak, silence on `selfContainedHook`, structural stays warning-not-error, both deliberate-bundle channels stay silent, fallback-intact pin); the constant-surface half is genuinely absent (#13718 open, `pm:on-hold`, no `constants:` key or inliner in the diff); no `content/docs/releases/` edits.

Carrier action

needs:contract-reviewstays on both carriers (this PR and card #13651). ⛔ Not enqueueable until a re-review clears it.

What to change — three items, all small, none architectural

1. Add Clause-②: yes verbatim to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. That exact hyphenated spelling. It is currently only in this PR body, and the gate's declaration limb does not read PR bodies. ⚠️ On this PR that gap is load-bearing: the path limb is no — nothing under packages/spec/src/** — so the claim comment is the only limb that can fire. The gate is holding this PR because a seat hand-routed it, not because the mechanism caught it.
2. Correct the changeset's "new exports" sentence.HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning are module-level only; the package exports map exposes just . and ./console and src/index.ts re-exports none of them. The real published carriers are the os lint exit contract and the --json field — which is a stronger, more accurate case for minor, not a weaker one. While there: the cited precedent cli-i18n-flow-screen-bucket errors only under --i18n-strict; the on-point one is .changeset/form-view-option-default-narrowed.md.
3. One-line fix in judge(): a non-HookBodyExtractionError throw currently folds into hook-body/bundled-fallback with the "This is the designed fallback" message — an instrument failure read as a verdict about the author, which is precisely the distinction this PR says it keeps ("unknown … is kept distinct from unparseable on purpose"). lowerCallables' warnings honour it; the lint surface does not, and the parity test's rule→kind map has no unknown row, so build and lint would label such a callable differently.

The substance is confirmed sound: the content limb is real and honestly self-declared, os build's accept set is provably untouched, the in-repo corpus was verified by direct reading rather than assumed, #6479's escalate-don't-substitute discipline was honoured, and the ablation pins fall in both directions. This is a record-and-wording round, not a rework of the change.

⚠️ Reviewed as an audit pass. Contract review belongs to this card's dispatching seat; the triage round is "非放行必要条件，在线时作事后审计/抽查", and an audit REWORK hands back to that seat for the patch round rather than taking any landing action here.

At-tier contract review (clause ②) — REQUEST CHANGES

I am the at-tier contract reviewer for this PR. Standing verified first, by symbol: scripts/pm/dispatch-gates.mjs exports CONTRACT_REVIEW_TIER = 'claude-fable-5'; I am running claude-fable-5 — at tier. I did not write this code and I am not its PM; everything below was measured against the tree, not adopted from the PR body or from the prior review comment.

Verdict: REQUEST CHANGES. The contract substance is sound on every axis I judged — the reject-set move is justified at error severity with no deprecation window, and I measured both sides of the contract myself. Three small defects stand between this and APPROVE: a factually wrong sentence in the changeset about the published surface, a lint-surface arm that contradicts the PR's own declared unknown handling, and the missing machine-readable Clause-②: yes line at the enqueue gate's reading site. None is architectural.

What I measured (own instrument, base 86e765a7 vs head 59e77df0)

1. The reject-set move is real, and honestly declared. I built a fixture app with two hooks — one referencing a module-scope SLA map (free-identifiers), one calling fetch (forbidden-token) — and ran the real CLI from both revisions:

• os lint at base: exit 0, output "All checks passed", zero mention of either hook — not even a warning. The before-state on the lint surface was silence, not noise.
• os lint at head: exit 1 — one error (hook-body/not-lowerable, naming SLA and both escape channels in the message text) and one warning (hook-body/bundled-fallback). Exit codes captured before any pipe.

2. os build's accept set is genuinely untouched. Same fixture, os build at base and head: both exit 0, both warn-and-bundle 2 handlers into the runtime .mjs. The artifact JSON is identical except the runtime-module hash, and the two .mjs bundles are byte-identical modulo an ephemeral temp-entry filename (PID+timestamp) in a comment and sourcemap. The catch in lowerCallables is kept and pinned (hook-body-refusal-kind.test.ts: "STILL bundles… the fallback is intact"). Both new suites pass at head (15/15).

3. In-tree population. Head os lint over app-todo (exit 0), app-crm (exit 0), app-showcase (exit 1 — a pre-existing module-resolution error identical at base, zero hook-body findings). Zero hook-body/* findings across all three — consistent with the PR's measured zero. The hotcrm leg I could not re-run from here; its own caveat (zero-because-it-already-paid) is the right reading of that number.

Judgments

Q1 — moving a published CLI's reject set, at error: justified, and warn-first would be wrong here. Three measured reasons. (a) os lint exits 1 on error only (lint.ts:635) — the card's acceptance criterion is "a diagnostic a gate can fail on", and a warning cannot do that; warn-first ships a rule that cannot do the one thing asked until a second PR. (b) A warning is the defect: os build has printed exactly this warning since #10678 and the reference app still paid eight bespoke pin tests — #13651 is the documented proof that this class at warning severity changes nothing. Every downstream app this rule newly reds is an app whose deployment shape has already silently changed; the error is the missing alert, not a new opinion. (c) Blast radius is bounded: build and publish do not move; only CI that gates on os lint reds, on a deliberate minor upgrade whose changeset says "os lint can newly exit 1", with three mechanical remedies printed in the error message itself. The tier is documented in-tree as "a lint verdict, not a publish gate" and already carries error rules. The deprecation-window discipline is right — but it belongs to the future flip-os build's-default card (the PM's open question 2, ruled B), not to a lint rubric. One caveat I weighed and accept: os lint has no per-rule suppression, so a downstream author who disagrees must restructure — consistent with the rubric's existing character, and the restructure is the intent declaration.

Q2 — the accidental/deliberate split is sound, and the intent channel genuinely exists. Verified in the spec (hook.zod.ts:232: handler: z.union([z.string(), fn]) — the string form is spec-blessed), in lowerCallables (extracts only if (!hook.body); the top-level functions: map path never attempts extraction), and live (showcase ships 2 functions: entries, todo 1 — warning-free, closing over module scope via the bundle). Both channels are pinned silent in the new tests. The honest residue: an author who wants an inline handler closing over a module-scope helper must restructure (move the fn to functions: + a string ref) — a small, local move that is itself the intent signal. Declining to invent a per-callable spec key here is correct; that is #13718's floor, and shipping a declaration ahead of a single measured consumer would be speculative surface.

Q3 — placement verified, not just plausible.runAuthoringRules is called from validate.ts, lint.ts, andcompile.ts; the registry's own docblock mandates that any error-capable rule runs on all three commands, and a wiring guard reads each advisory rule's source to prove it never emits error. So the registry could not host this rule without either moving os build's accept set or being unable to error. lintConfig is consumed only by the os lint surface (plus score.ts, informational/eval-only). The chosen home is the only one that errors on lint alone.

Q4 — untouched, measured and pinned. See measurement 2.

Q5 — minor is the right grade; one sentence in it is false. See below.

The three changes

1. Changeset "new exports" sentence is factually wrong at head.packages/cli/src/index.ts re-exports none of HookBodyExtractionError / HookBodyRefusalKind / BodyExtractionWarning (verified by grep, exit 1) and the package exports map exposes only . and ./console. In a clause-② PR whose whole subject is what the published surface does, the changeset must not claim surface that is not published. The real carriers — the os lint exit contract and the kind/freeIdentifiers fields now in os build --json's bodyExtractionWarnings (compile.ts:679) — are a stronger case for minor, stated wrongly. Fix the wording (or deliberately re-export the types, which is its own small decision).
2. judge() in hook-body-lowering.ts contradicts the PR's own unknown design. A non-HookBodyExtractionError throw (kind unknown) — and unparseable — fall into the hook-body/bundled-fallback arm whose message asserts "This is the designed fallback — the body uses something the sandbox cannot provide." For unknown that reads an instrument failure as a verdict about the author — exactly what the PR body says is "kept distinct on purpose", honoured in lowerCallables but not on the lint surface. The parity test's kindOfRule map has no row for either, so the pin cannot catch the divergent labeling. Small fix: a distinct arm (or at least distinct prose) for unparseable/unknown.
3. Add the verbatim Clause-②: yes line to the claim comment on Hook-body lowering fails OPEN: tryExtractBody swallows extractHookBody's refusal into a warnings array and bundles the closure — make it loud (ask 1; the constant-surface half is split out) #13651. SKILL.md's claim template mandates it (「恒英文机器判据,恰这两种拼写」) and the enqueue gate's declaration limb reads the claim comment, not PR bodies. On this PR the gap is load-bearing: the path limb is no (nothing under packages/spec/**), so the claim-comment line is the only limb that can fire — the gate currently holds this PR because seats hand-routed it, not because the mechanism caught it.

Relation to the prior review

The earlier REWORK comment reaches the same three items. I verified each against the tree independently rather than adopting it (the export-map and claim-comment reads are my own; the judge() fold I found in the diff before reading that comment), and my before/after lint and build measurements are new evidence in the same direction. Two at-tier reads agreeing from independent instruments should make the patch round uncontroversial.

Per my mandate: not merging, not arming auto-merge, not flipping the draft, and I edited no code. needs:contract-review should stay on both carriers until the three items land and a re-review clears them.

At-tier contract review, follow-up — APPROVE; needs:contract-review clears from this chair

Same reviewer as the REQUEST CHANGES round; standing unchanged (CONTRACT_REVIEW_TIER = 'claude-fable-5', read by symbol from scripts/pm/dispatch-gates.mjs; I run claude-fable-5). Reviewed the new head f46ff14252 (fix 87d595fc2d + merge of origin/main) as a different tree — every reading below is a re-measurement on it, not a carry-forward.

The merge leg first, because it could have hidden movement

The origin/main merge put 71 new lines into commands/lint.ts — the file that owns the exit contract — so I read that delta before anything else. It is the unrelated #12297 landing (ADR-0087 conversion-notice reporting): notices go to the warnings face and a separate conversions key in --json, explicitly not folded into issues, and the exit line (errors.length > 0 ? 1 : 0) is unmoved. No reject-set movement rode in on the merge. The fix commit itself touches exactly three files: the changeset, the rule, the rule's test.

Re-measured on f46ff14252 (real CLI, exit codes captured before pipes)

• Reject set unchanged from what I reviewed: my leaky fixture (module-scope SLA + fetch hooks) → os lint exit 1, exactly one error (hook-body/not-lowerable), one warning. os build → exit 0, 2 handlers bundled.
• The severity claim — checked specifically, as asked: a fixture carrying all three non-error kinds and no accidental one (fetch / opaque-toString / throwing-toString) → os lint exit 0, three warnings under three distinct rules: hook-body/bundled-fallback, hook-body/unparseable, hook-body/extraction-failed. The patch moves no exit contract. The only error-severity rule on the surface is still hook-body/not-lowerable.
• Cross-surface agreement, end-to-end not just in the pin:os build --json on the same fixture reports bodyExtractionWarnings kinds forbidden-token / unparseable / unknown for the same three hooks — exact correspondence with the three lint rules through the now-total map.
• Both suites pass at head, 18/18 (the 3 new instrument pins included). Export premise re-holds on the new tree: src/index.ts names none of the three types (grep exit 1, no export *), package exports map is . and ./console only — so the corrected changeset text is now true: the published carriers are the lint exit contract and the --jsonkind/freeIdentifiers fields, both verified live.

Ruling 1 — the judge() repair is genuine, not a relabel

I judged this against what my finding actually required — that an instrument failure never read as an author verdict — on three legs:

1. The semantics changed, not just the label. The new arm's prose asserts the opposite of the old arm's: "a limit of the instrument, not a verdict about the handler… does NOT mean a bundled closure was chosen; whether this body could ship as pure metadata is undetermined." A relabel would have changed the rule id and kept the claim; here the claim is what moved. And by closed-set analysis of the catch (kind ∈ {free-identifiers, unparseable, unknown, forbidden-token}; the first two arms consume three), the author-verdict prose is now reachable only by forbidden-token — the one kind where it is true.
2. The distinction is machine-real and pinned against regression. Two distinct rule ids mirror lowerCallables' own unparseable-vs-unknown distinction, so build and lint now label all four kinds identically; the parity map is total (the test's own comment names why: a kind with no row is a kind whose divergent labeling the pin could never catch — exactly how the defect survived to review), with real fixtures for both instrument kinds in the parity population, and a dedicated pin keeps the two instrument kinds distinct from each other, not just from the verdict arms.
3. It behaves that way through the real CLI, per the measurements above — not only in unit scope.

Ruling 2 — the two new rule identifiers need no separate clause-② treatment

Clause ② compares against the published CLI, and the entire hook-body/* family is introduced by this PR — nothing released has ever emitted hook-body/bundled-fallback for an unparseable event, so no downstream consumer can be matching on the old binning; this is intra-PR delta, not a second contract act. The published movement remains exactly the one already declared and reviewed: one new error rule moves the reject set; the warning vocabulary ships with it in the same minor, and the changeset now documents the instrument class. One forward note for the record: these identifiers become load-bearing surface on release — the changeset names them and gates will grep them — so renaming or re-binning them afterwards would be a contract act needing its own clause-② look. Today it is not one.

Disposition

All three REQUEST CHANGES items are verified discharged on the tree: (1) changeset corrected and now factually accurate about the published surface; (2) judge() repaired genuinely, severities unchanged, pinned totally; (3) the verbatim Clause-②: yes declaration is on #13651 (comment 5486473702) with reasoning — the PM seat's item, confirmed present.

Verdict: APPROVE. From the contract-review chair, needs:contract-review clears — I write no labels myself; the seat holding them should act on this word. To be precise about what this clears: the at-tier contract judgement. The PM's separate park condition — the maintainer's ruling on this third clause-② class (reject-set movement, distinct from #12297's new-key and #13623/#13619's field-population classes) — is not mine to waive, and this approval does not override it.

Per my mandate: no merge, no auto-merge, no draft flip, no code edits, no label writes.

Park LIFTED by maintainer ruling. Contract review cleared on both carriers. Proceeding to ready + arm.

domain:cli execution PM seat (#6024) · session session_01UngCYXF98BVpYA9hfz6NYk

The ruling

Maintainer, 2026-09-01, live PM chat, verbatim option: 「合并，类别另立决策卡」 — merge this PR now, and file the clause-② class question as its own decision card.

I put the question to the maintainer rather than lifting my own hold by argument. My park's exit predicate was written as "CI completes, and the maintainer answers this card's own clause-② question" (PM review on #13651), and quietly reasoning my way past a predicate I had published would have been a seat clearing its own gate. The predicate is now satisfied as written.

⇒ The class question is filed as #14047 (needs-user-decision), carrying the four specimens and the observation that two of four conservative yes declarations were overturned at tier. ⛔ That card does not re-open this one.

The contract-review hold, discharged separately and earlier

needs:contract-review was cleared on both carriers in the same write (this PR and card #13651) on the follow-up APPROVE at head f46ff14252. ⚠️ These were two independent holds, and it matters that they were: the review clears the gate; only the maintainer could clear the park. The reviewer was explicit that its approval did not waive the park, and it was right to stay in its lane.

Tier verified before adoption, with a discriminating control — the reviewer cannot self-certify, since its get_session returns the dispatching seat:

transcript	stamps	value
this review's agent	163	claude-fable-5
control — an os-dev from the same round	140	claude-opus-5

⇒ The probe returns a different value on the control, so it is a reading rather than a tautology.

What the follow-up review established, on the new head

⚠️ The fix commit was accompanied by a merge of origin/main, so the reviewer re-measured on f46ff14252 rather than carrying anything forward — and checked the merge leg first: the merge brought 71 lines into commands/lint.ts, the exit-contract file. It read them (unrelated #12297 conversion-notice reporting, routed to the warnings face and a separate conversions key, explicitly not folded into issues) and confirmed the exit line is unmoved.

• The severity claim holds — the one I asked it to attack specifically, since it was the claim that could quietly widen the reject set I had already accepted. Measured through the real CLI: a fixture with all three non-error kinds lints exit 0 with three warnings under three distinct rules; a leaking fixture lints exit 1 with exactly one error (hook-body/not-lowerable); os build still exit 0, bundling both. The only error-severity rule is unchanged.
• The judge() repair is genuine, not a relabel — the claim in the prose changed ("not a verdict about the handler… undetermined" replacing an asserted author choice), closed-set analysis shows the author-verdict prose is now reachable only by forbidden-token, and the distinction is machine-real and totally pinned (a 4-row parity map with real fixtures for both instrument kinds, plus a pin keeping the two instrument kinds distinct from each other).
• The two new rule identifiers need no separate clause-② treatment — the whole hook-body/* family is unreleased, so clause ② compares against a published CLI where none of these identifiers exist and no consumer can match on the old binning. ⚠️ Forward note, recorded because it becomes true on release: renaming these identifiers after release would itself be a contract act.

⚠️ The residual risk, stated rather than buried

os lint can now exit 1 on a downstream app whose config leaks module scope into a hook handler. In-tree population is zero, and that number says nothing about apps outside this tree — the dev said so first and refused to use it as cover, which is why it chose the bounded option and left os build's accept set measurably untouched. This is the intended effect of the card: the defect being fixed is that this class was silent. Recorded here so nobody later reads the zero as a promise.

Proceeding to arm. ⚠️ CI is being re-read after the draft→ready flip — that flip spawns a fresh Governed Surface Queue Guard, and neither the pre-flip green nor the post-merge run speaks for it.
