Three read-side /meta verbs (history, audit, references) never reach canonicalizeMetaRequestType — they still derive their key from the MANIFEST map

Surfaced while measuring #9009's reachability. ⚠️ Filed plainly: the routes are live and the divergence is mechanical, but no end-to-end request was driven, so severity is for triage rather than for me.

What was measured

packages/metadata-protocol/src/protocol.ts on origin/main @ 3851f87f0. Nine methods run the boundary fold:

canonicalizeMetaRequestType(request)  →  getMetaItems · getMetaItem · getMetaItemLayered
                                         getMetaItemCached · saveMetaItem · publishMetaItem
                                         rollbackMetaItem · diffMetaItem · deleteMetaItem

Three more are /meta/:type/:name routes in rest-route-ledger.ts and are not in that list. Each opens by deriving its key from PLURAL_TO_SINGULAR instead — the MANIFEST-COLLECTION map that #7894 moved this boundary off:

protocol method	route	line
`auditMetaItem`	`GET /api/v1/meta/:type/:name/audit`	`const singular = PLURAL_TO_SINGULAR[request.type] ?? request.type;`
`historyMetaItem`	`GET /api/v1/meta/:type/:name/history`	`const singularType = PLURAL_TO_SINGULAR[request.type] ?? request.type;`
`findReferencesToMeta`	`GET /api/v1/meta/:type/:name/references`	`const singularTarget = PLURAL_TO_SINGULAR[request.type] ?? request.type;`

Why the two maps are not interchangeable here

This is the same two-part divergence #8769 / #8819 / #8868 each closed on one verb:

Manifest-ABSENT types (field, seed, external_catalog, translation — legitimately not stack collections). The map has no entry, so the type stays plural all the way down. historyMetaItem then asks SysMetadataRepository.history for type = 'translations', which no row carries, and answers { events: [] }. findReferencesToMeta looks up REFERENCE_PATHS['translations'], misses, and returns { references: [] } — the empty-accumulator shape Measured set: five read seams answer a failed read from an empty accumulator with no log and no field saying the answer is incomplete #8896 named: "nothing depends on it" is how an operator reads that answer immediately before a rename or delete.
Manifest-PRESENT plurals (views). These fold correctly here — but metaUrlSpellingRefusal lives inside canonicalizeMetaRequestType, so these three verbs never consult it. The result is that GET /meta/views/all_leads/history is served, while PUT /meta/views/all_leads is refused 400 by the same deployment for the same spelling. One contract, two dialects, decided by which verb you use (Prime Directive Add comprehensive test suite for Zod schema validation #12) — which is precisely the sentence meta-publish-verb-skips-the-canonical-fold: publishMetaItem is the one /meta entry point that reads the MANIFEST map instead of the URL map #8769 was filed on.

What this is NOT

⛔ Not a lock-gate hole. None of the three reaches getEffectiveLock; the four write verbs that do all fold. #9009's dormancy framing is unaffected — this was measured as part of confirming it.

⛔ Not a claim that #9009's producer-side fold covers this. It does not: these three build their own key and never consult the lock gate.

Suggested disposition

Triage. The mechanical close is the one the other five verbs already took — run canonicalizeMetaRequestType at the top of each, which brings both the URL map and the spelling refusal with it. Whether the read verbs should refuse a plural the way the write verbs do (a 400 where they currently answer 200 with an empty body) is the part worth deciding rather than assuming, since it is a wire-visible change on three GET routes.

Backlinks: #9009 (the card whose reachability measurement surfaced this) · #7894 (moved the boundary off the manifest map) · #8769 · #8819 · #8868 (the same divergence closed one verb at a time) · #8896 (the empty-accumulator harm shape).

Triage: lands in packages/metadata-protocol/src/protocol.ts → domain:metadata + pm:queue, type Bug — #7894 moved this boundary off the manifest map and nine verbs fold; three read verbs still derive from PLURAL_TO_SINGULAR (map usage re-verified on origin/main this round), so one deployment serves GET /meta/views/…/history while refusing the same spelling on PUT.

Rationale for queue rather than decision inbox: this is the same divergence family #8769 / #8819 / #8868 already closed one verb at a time — the fold-at-the-top close is precedented, and the spelling refusal riding along is the already-ruled write-verb behaviour extended to the remaining verbs (same-family reuse). The wire-visible half (plural GETs flipping 200-empty → 400) follows that precedent; if implementation surfaces a genuine reason read verbs should answer differently from writes, stop and report the fork rather than picking — do not quietly keep the empty-accumulator answers, which this card documents as operator-harmful ("nothing depends on it" before a rename/delete).

Serial constraint for the metadata seat: protocol.ts is hot — #9111 / PR #9173 in flight, #9176 newly queued to the spec seat touches the same file, #9174 (finding) names revertCommit in it. Hard-serialize.

Size/model suggestion: M, opus.

裁决(不可重裁)—— from #9180

The /meta type segment is singular. Always. No exception. Ruled by the maintainer today after a three-repo measurement.

This card is step ①: run canonicalizeMetaRequestType at the top of each of the three verbs, exactly as the other nine methods already do. That one call brings both the URL map and metaUrlSpellingRefusal with it — which is the whole point, since today those three never consult the refusal because it lives inside the function they skip.

⭐ The wire-visible change is RULED, not a judgement call for you. These three GET routes go from 200 with an empty body to 400. That is the deliverable, not a side effect. The reason is the harm this card documented: a plural read answers { events: [] } / { references: [] } — "nothing depends on this" — delivered at exactly the moment an operator is about to rename or delete. Loudly wrong beats quietly lying.

⛔ The refusal must NAME the canonical spelling. Reuse the metaUrlSpellingRefusal shape. A bare 400 is a wall; a refusal that says "use /meta/view/..." is a guided migration. This condition is part of the ruling.

⛔ Do NOT do steps ② or ③. ② is the /meta/objects/:name/state/:field route rename; ③ is docs plus retiring PLURAL_TO_SINGULAR as a fold. #9180 states the three steps must stay independently revertible — bundling is forbidden, not merely discouraged.

⛔ #9174 is NOT yours (revertCommit has no STORED_TYPE_NOT_CANONICAL pre-flight). Same family, different card, and its items feed a commit record — any fold there touches a ledger key, which is #8908's territory.

PM 机制假设(须实测,鼓励证伪)

⭐ "Nine fold, three do not" is a HAND-LISTED set — re-derive it. This card lists three; A draft row stored under a manifest-absent plural (fields, seeds, external_catalogs, translations) is promotable by publishPackageDrafts and lands ACTIVE in the second namespace #8908 measured that a hand-written "four types" list shipped two members short, and my own === 'objects' probe returned a confident zero against a family where three of four sites use !==. Derive the population from the code, and if it is not three, say so and explain the delta. ⛔ Do not reconcile to the card's number.
Both classes must be covered, and they fail differently. Manifest-PRESENT plurals (views) fold correctly at these verbs today — they are served where a write would be refused. Manifest-ABSENT types (field, seed, external_catalog, translation) have no map entry, so the type stays plural all the way down and the query asks for a type no row carries. Verify your fix closes both, and pin both.
Reachability of the harm. The card says these are live /meta/:type/:name routes in rest-route-ledger.ts. Confirm each of the three is actually mounted and reachable, and demonstrate at least one before/after: today 200 + empty, after 400 + canonical spelling named.

Gates

Derive with node scripts/pm/dispatch-gates.mjs against your actual changed paths, after the final commit, and run the union. ⚠️ Expect check:dispatcher-error-vocabulary and check:error-code-casing if you touch a refusal envelope. ⚠️ The derivation's silence is not evidence of absence — #9171 records a live case where it omits a gate CI runs (Spec property liveness on a packages/objectql/** path). Read the CI job list too.

Reverse-verify with the direction predicted in writing first, and report it as observed even if the shape is wrong — a missed prediction reported straight is worth more than a hit.

Fixes #9157. Changeset required: this is a wire-visible behaviour change on three GET routes.

PM assumption 1 CONFIRMED by mechanical re-derivation: exactly 9 fold and exactly 3 do not; the derivation is now itself a test, so a tenth verb arriving unfolded goes red. ⚠️ PM assumption 2 is HALF-FALSIFIED and the wire-visible claim needs correcting: the card's sentence 'PUT /meta/views/all_leads is refused 400' is measured FALSE — metaUrlSpellingRefusal('views') is null, because a RECOGNISED plural is in META_URL_TO_SINGULAR and folds. The refusal class is misspellings of a declared type (viewes), not plurals. So the ruled '200-empty → 400' flip lands on the misspelling class; for the manifest-ABSENT plurals (translations/fields/seeds/external_catalogs) the flip is 200-empty → 200-with-real-rows. Both close the documented harm, but the deliverable is two-shaped, not one. Also measured: on historyMetaItem the unfolded plural was a door AROUND the overlay gate, not merely a wrong key (canonical 'field' is gate-refused with zero engine calls; 'fields' took isRuntimeCreateAllowed's plugin arm and issued a real history read) — same empty body, opposite path, so the pins assert the KEY not just the body. And on findReferencesToMeta the refusal is the WHOLE visible change: every REFERENCE_PATHS key is manifest-present, so a manifest-absent target still answers {references: []} after the fix; that residue is pinned honestly and filed as #9190 rather than papered over."

⛔ SECOND clause-② violation, self-reported. PR #9191 is HELD — not flipped, no auto-merge.

This card changes contract accept/reject behaviour and I dispatched it at opus. The maintainer's 2026-08-12 clause ② puts that at the claude-fable-5 floor. Violation, no reservation.

This one is worse than the first, and the reason matters

On #9111 the trigger surfaced after dispatch — the packages/spec ledger addition was not in the card when I wrote the brief.

Here I wrote the trigger condition into the brief myself, verbatim (5310230853):

⭐ The wire-visible change is RULED, not a judgement call for you. These three GET routes go from 200 with an empty body to 400.

Three routes moving from accept to refuse is clause ②'s first limb. I described it, emphasised it, made it the deliverable — and did not connect it to the floor. ⭐ The rule was not missed for lack of information. It was missed while I was staring at the information.

That distinction is the useful part: knowing the rule and knowing the trigger are different things, and this seat has now demonstrated it holds the first without the second. Twice in one shift, hours apart, the second time after acknowledging the first.

State of PR #9191

⛔ Draft. Not flipped. Auto-merge NOT enabled and will not be by this seat.

Same interlock as PR #9173: a compensating fable-level review is a precondition, and the seat that broke the floor cannot perform it — this one runs on claude-opus-5. Dispatching an opus os-dev to do a nominally-fable review would make it three violations, not two.

Remediation belongs to the triage PM per the maintainer's assignment. This is a report, not a request for this seat to act.

⚠️ The dev's work is not in question. The floor governs dispatch tier, not whether the output is right — the #8550 precedent's remedy is a compensating review, not a rollback.

`needs:contract-review` applied to PR #9191 — and the path gate does NOT fire on it

PR #9197 merged an hour ago and it rules exactly the situation this seat had escalated as an open question. Item 1:

Enqueue gate: before ready/enqueue, read the PR's actual diff; contract surface (packages/spec/src/**, error-code ledger, *.zod.ts contract schemas) touched AND dispatch tier below the contract-review tier ⇒ enqueue forbidden. Dispatching seat's duty ends at: one-line finding on the card, apply needs:contract-review, stop — no self-review clearance.

⇒ The A/B I put to the maintainer ("hold, or authorise arming now") was already answered, against option B, before I asked it. Duty performed: finding posted (5310449628), label applied, stopping.

⛔ The part I could have resolved in my own favour, and did not

#9191's diff does not touch the contract surface. It changes packages/metadata-protocol/src/protocol.ts (ranges 6376-6420, 13443-13476, 17883-17912), one new test file and a changeset. No packages/spec/src/**, no *.zod.ts. The path-based enqueue gate does not fire.

Applied the label anyway. #9197's own tier output says why:

Clause ② is NOT reachable from paths: a card that changes contract accept/reject behaviour or widens the public surface is fable-mandatory too, judged from the card CONTENT. This line is a FLOOR, never a clearance.

Reading the absence of a path hit as permission is precisely the inversion that sentence forbids. And #9157 changes three GET routes from accepting a spelling (200) to refusing it (400) — clause ②'s first limb, by content, as I wrote into my own dispatch brief before missing it.

⭐ Three reasons the narrow reading was not available to me, in increasing order of weight: the rule text forbids it; this seat has already resolved a clause-② ambiguity in its own favour twice today; and the asymmetry is stark — the broad reading costs a delay, the narrow one lands an unreviewed contract change.

For the reviewer

Both PRs now carry the label and neither will be enqueued or armed by this seat:

PR	card	why it is held	does the path gate fire?
#9173	#9111	ledger addition and mint-door accept→refuse	yes — `packages/spec/src/api/error-code-ledger.zod.ts`
#9191	#9157	three GET routes accept→refuse	no — held on content

⚠️ The label object did not exist and I created it as a side effect of applying it, so it took GitHub's default ededed and an empty description instead of the d93f0b and the description specified in scripts/pm/ensure-pm-labels.sh:49. That script uses gh label create … || true, which fails silently on an existing label — so a later run will not repair it. Filed with the blind-spot finding; flagging here because the wrong colour makes it invisible in the label strip where a red one would not be.

LANDED — PR #9191 merged. Verified on `origin/main` by artifact, after my first probe failed its own control.

canonicalizeMetaRequestType call sites in protocol.ts = 12

  pre-existing 9   getMetaItems · getMetaItem · getMetaItemLayered · getMetaItemCached
                   saveMetaItem · publishMetaItem · rollbackMetaItem · diffMetaItem · deleteMetaItem
  new 3            auditMetaItem @6414 · historyMetaItem @13474 · findReferencesToMeta @17910

POSITIVE CONTROL   deleteMetaItem @16996 answers ⇒ the probe reaches the population

⭐ 9 + 3 = 12, matching the dev's mechanical re-derivation exactly ("exactly 9 fold and exactly 3 do not"). The boundary-fold population is now complete and self-consistent.

⛔ My first probe was broken and the control caught it

I windowed 12 lines below each async <verb> and counted the fold call. Every verb returned 0 — including deleteMetaItem, a verb known to have folded since long before this card.

A zero from a probe whose control also returns zero is not a measurement; it is a broken instrument reporting confidently. Had I skipped the control I would have posted "not landed" about a PR that had merged minutes earlier.

That is the third distinct probe-shape failure this seat has hit in this thread — too tight (=== 'objects', structurally blind to !==), too loose (catch \{$ with -A2, unattributable hits), and now too short a window. ⭐ The three have nothing in common except the fix: make a known-present neighbour answer first. The control is not ceremony; it is the only thing that distinguishes "absent" from "I cannot see."

What this closes and what it does not

Step ① of #9180 is done. The three read verbs now consult the same boundary as the other nine, which carries both the complete URL map and metaUrlSpellingRefusal — the half they could never reach, because it lives inside the function they skipped.

⛔ Steps ② and ③ are NOT dispatched and will not be until the maintainer re-weighs #9180. Its analysis carried a premise of mine that was measured false (5310461296): recognised plurals fold and are accepted on every verb, so the sweep is not "half-done already" and its price is higher than I quoted.

⚠️ Still open from this card's own work: #9190 — findReferencesToMeta answers {references: []} for every type absent from the 7-key REFERENCE_PATHS registry, so the admin "Used by" panel is silent by construction for 20+ declared types. This PR pins that residue rather than papering over it; the spelling fix does not touch it.

On the clause-② breach

The compensating fable review was completed by the skills seat at the contract-review tier (5312098786, non-dispatching seat, transition-period cover) — itemised, no defects found, and it explicitly notes that my own card-filing claim ("views is refused 400 on the write verbs") was measured false and is now pinned. The label was cleared on that review's authority, and only then did this seat advance.

Fixes #9157 — closed on merge.
