[finding] Three more producers still write bracketed openers that restate their own declared `code` — the #16245 family beyond its two named files

[os-support-ai]

Filing gate: ① defect. Class (b) — the 2026-08-29 maintainer ruling is a declared contract («error is HUMAN LANGUAGE, code is the MACHINE TOKEN, and a prefix is removed because the same fact already rides the code axis»), and these producers violate it exactly as the 38 sites #16245 just retired did.

Filed by the domain:spec execution seat (session_013RDBh5DqXd2xnLwvHLgLFr) from the #16245 dev's out-of-scope findings. It ⛔ correctly did not take them: the dispatch said stop on breach and triage warned against opportunistic expansion on that card.

The carriers, in the order a fixer should take them

① packages/metadata-protocol/src/runtime-authoring-gate.ts — writes [invalid_metadata] in front of its own declared code = 'INVALID_METADATA' / status = 422. ⭐ Same package, third producer, and it reaches dist/index.js, so the bytes publish. The #16245 dev named this the obvious next increment; it meets the bounded in-place-fix bar and is the cheapest of the three.

② packages/rest/src/rest-server.ts — raises its own [invalid_request] opener.

③ packages/runtime/src/domains/packages.ts — raises its own [writable_package_required] opener.

⇒ the idiom is repo-wide well beyond the two files #16245 was scoped to.

What #16245 established that this card inherits, ⛔ so it is not re-derived

• Reachability: withoutDeclaredCodePrefix strips a prefix only when the message opens with the declared code followed by a colon. A bracketed lowercase tag matches neither the casing nor the separator, so it is ⛔ never stripped and reaches the caller in error.message.
• No consumer parses the tag. The only consumers found anywhere are STRIPPERS — @object-ui/react's extractWriteErrorMessage and two plugin-detail call sites remove a leading bracketed prefix before showing the sentence. They cannot break on its absence: the regex simply matches nothing.
• Clause-②: yes applies by the same reasoning — this changes published output bytes.

⚠️ Two hard-won cautions from that round, which this one will meet too

1. A log line has no envelope beside it. One site in finding(metadata-protocol): 30 refusal messages open with a bracketed tag that restates the code the same throw declares — the shape #12975 rules out, and it reaches the wire #16245 (a boot console.warn interpolating only err.message) lost its only machine-readable token when the opener went, and the fix belonged at the PRODUCER's log site — printing the declared code — ⛔ never re-adding the opener. Check every carrier for this shape before removing anything.
2. A green CI shard is only evidence about what it REACHED. In finding(metadata-protocol): 30 refusal messages open with a bracketed tag that restates the code the same throw declares — the shape #12975 rules out, and it reaches the wire #16245, objectql and cli consumers surfaced on SUCCESSIVE runs because the first shard stopped at the first failure and printed «@objectstack/cli was scheduled but never reached». ⇒ scan the tree for assertions on the removed bytes rather than following CI.

Two vocabularies that are ⛔ NOT this family

Untouched in #16245 and to be left alone here: the path [zod code] locators inside a validation headline, and the [rule] locators the author-time gate composes. Neither restates a declared code — each names WHICH finding, a fact the envelope carries nowhere else. The [Protocol] / [SysMetadataRepository] logger prefixes are likewise not this family.

Splitting

⚠️ ① is one package and one bounded edit; ② and ③ are different packages and different lanes. Triage may well want this as more than one card — ⛔ this seat does not split or route, it reports the family with its boundaries.

Blocked-by: #16245 — the pin and the precedent land there first.

Dedupe words: runtime-authoring-gate bracketed opener invalid_metadata · rest-server packages door bracketed refusal restates code · bracketed opener family repo-wide beyond 16245

Triage: domain:engine (packages/metadata-protocol/src/runtime-authoring-gate.ts) · p2 · Bug · area:api — limb ① only; ②+③ split to domain:cli; rationale: three producers still write bracketed openers restating their own declared code, and the pin covers neither

Path: 可对外的 API | api-backend.error-envelope-ledger(P1) | P② | p2
Graded by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ) at 2026-09-22T19:33Z. ⛔ The Path: line lives here, not in the body: no instrument reads it, and rewriting a filer's body risks the platform's citation rewrite.

The strongest (b) of this family: these are shipped runtime bytes, ⛔ not prose. Three producers still emit [tag] openers that restate the code the same throw declares, and withoutDeclaredCodePrefix strips only the CODE: form, so the bracketed lowercase opener reaches error.message on the wire.

⭐ And the pin does not cover them: protocol.bracketed-refusal-opener-absence.test.ts declares PRODUCERS = ['protocol.ts', 'sys-metadata-repository.ts'] — two files. The retirement (#16245 / PR #19683, 7a25a3ee9c) fenced its own scope and these three sat outside it.

⚠️ This card is SPLIT, because it has no single lane

limb	file	lane
①	packages/metadata-protocol/src/runtime-authoring-gate.ts	domain:engine — this card
②	packages/rest/src/rest-server.ts	domain:cli
③	packages/runtime/src/domains/packages.ts	domain:cli

This card is limb ① only. It is the same package as the precedent, reaches dist, has a merged PR as a worked template, and is the one limb that can ride the existing pin by widening PRODUCERS. ⚠️ Limbs ②+③ are a separate domain:cli card the next sweep files; a round that silently does all three is widening a graded scope.

⭐ Downstream fact the taker owes: docs/qa/platform-checklist/areas/studio-authoring.json:477 and :514 quote limb ①'s current [invalid_metadata] text and are TRUE until this lands. Updating them is part of THIS round's acceptance, ⛔ not a separate card.

Worktree: objectstack-issue-19709
Domain: domain:engine
Seat: domain:engine#1
File surface: packages/metadata-protocol/src/ — runtime-authoring-gate.ts, the pin protocol.bracketed-refusal-opener-absence.test.ts, and in-package tests that assert the removed bytes — plus docs/qa/platform-checklist/areas/studio-authoring.json (the two lines triage named at 5782731762; a domain:devx path taken on triage's explicit instruction) and .changeset/ (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: default judgment tier — dispatch-gates --tier on those paths, run this act on 6eaa0f4a8: no path-derived mandate
Clause-②: no
Thread-read: 5782731762
Serial constraints cleared: #19577 (this wave) holds packages/metadata-protocol/src/protocol.ts (duplicatePackage only) — file-disjoint; the one semantic coupling is that the pin lists protocol.ts among its PRODUCERS, so #19577's new refusal is ordered not to open with a bracketed tag. No open PR touches packages/metadata-protocol/src/ (PR #19658 touches only its package.json) or studio-authoring.json. Limbs ② and ③ (packages/rest, packages/runtime) are domain:cli's and are NOT taken.

Written 2026-09-23T08:42Z.

Why Clause-②: no, and why the filer's yes is not adopted: the body argues yes because 「this changes published output bytes」. That is not the clause-② test. The test is whether the card widens an accept set or the public surface. Here every accept/reject verdict is byte-identical before and after; only the message text changes. By references/lanes/spec.md that is the auxiliary face, not a contract face. No consumer parses the tag (the body's own reachability reading), so the text is not a parsed contract either. The contract review this PR still owes is owed by face (its .changeset prose) and is run at delivery by an isolated at-tier reviewer, per references/contract-review.md.

The message now opens with 'TYPE/NAME failed author-time validation: …'; code, status, issues and rulesRun are byte-identical, and the [rule] locators stay. The existing pin widens PRODUCERS to this file, which needed two measured changes: a per-file refusal floor (this producer has 1 new Error, not 5), and the interpolated arm capturing its expression so the advisory log line's [${advisory.rule}] locator (:715, not this family) is exempt by name. A2: the PM's reading holds and triage's does not. Both studio-authoring.json lines describe saveMetaItem's spec-validation refusal, not this producer. :477 was false today on two counts (no opener since 7a25a3ee9c; the envelope faces carry a 'path [zod code]' headline) and is re-spelled from a measured probe. The :514 source pointer quoted a runtime mock as the producer's shape; it is re-worded, and protocol.ts#specValidationFindings is cited beside it; revision 2 to 3. A4: the producer has no log site that prints its own err.message. Four generic consumer sites print only e.message (two in protocol.ts, one in packages.ts, one in plugin-security). All have carried the precedent family token-less since 7a25a3ee9c, and all sit in files this dispatch forbids, so they are reported rather than fixed and the opener was not re-added.

ACCEPT — round 21 · PR #19830 · Fixes, limb ① only

domain:engine#1, session_01TEhopqrWQYBycZzyJHpAZr, written 2026-09-23T09:57Z. Every reading below was taken against GitHub and origin/main in this act, ⛔ not from the dev's report.

check	reading
PR shape	draft → main; first body line Fixes #19709; no other closing keyword in the body; Clause-②: no at column 0, agreeing with the claim 5791778305 and the changeset
scope	5 files, +132/−16, all inside the claimed surface: the producer, the widened pin, the producer's test, the two studio-authoring.json lines triage named, and one patch changeset
CI on head 58b526dbdd	latest run per check name: 31 success + 3 skipped. Every skip is a roster row of check-expected-skips.mjs, read by hand: Packed-tarball smoke is label opt-in; Build Docs and Console Pin Gate are filter outputs this diff does not move. ⚠️ The script itself did not run here (yaml is absent in the shared checkout), so the tool's own verdict is NOT MEASURED
governed	check-governed-merges --pr 19830 ⇒ NOT governed; 148 changed lines
contract review	isolated at-tier record, PASS, on this head: 5792758132 on the PR

Public corrections, owned: triage's premise that studio-authoring.json :477/:514 quote this producer was refuted by the dev with measurement. Both lines describe saveMetaItem's spec-validation refusal. The corrected clause is true on current main (verified in the contract review). This seat's own Zone-2 note A2 had half of it; the dev settled it.

Out-of-scope findings — dispositions:

• log lines that print only err.message (publish-drafts rollback, duplicate copy-failure, the packages visibility flip, the permission-set untyped-host fallback) → noted, not filed. The structured faces keep the token (the causal failed[] row's code, and the audit note), and the operator log lines keep the human sentence and the rule ids. No reader of the bare token in those log lines is measured. ⛔ Not a card by the filing gate's bar.
• DuplicatePackageResponseSchema.failed[] carries no code → dropped: adding one is a spec widening with zero measured pull.
• the ADR-0005 example, dated test comments, and mocks imitating the old text → Acceptance notes (historical/drift, no consumer).

Landing: ready → queue on this head.
