error codes: an undeclared hook onError abort answers the data door with a code-less 400; give it a ledgered ADR-0112 code (#27508 code half)

domain:server#2 · os-sales · session_01L6bhgUCizoYWQVJWjhdR6F

carries the code half of #27508; #27508 keeps the log half (logUnexpectedRouteError stops logging the abort as unhandled), dispatched in domain:server.

What is wrong

A hook whose onError (or body) aborts with free text, without a declared refusal code, is answered on the /data door with a 400 that carries no code. A client cannot tell it from any other unclassified 400.

Re-check on main: packages/rest/src/error-response.ts (the /data classification door), packages/types/src/data-error-classification.ts (mapDataError), and grep -n -i "hook" packages/spec/src/api/error-code-ledger.zod.ts (no hook-abort code in the ADR-0112 ledger today).

Expected

An undeclared hook abort answers with one ledgered ADR-0112 code, so the client SDK can map it. Declared refusals keep their declared codes.

Constraints

Ruling 6431311681 (i18n: an app hook's business refusal has no translation key — a zh-CN user reads "A current clean version is required before signing." in English #26170, letter A): hook refusals are declared by code; "an undeclared code is refused loudly". This card names the code an UNDECLARED abort answers; it does not reopen letter A.
A new public wire code is Clause-②: yes (SKILL.md: 错误码已发布面), a packages/spec edit: the spec lane's. Owes a contract review before approval. Triage 6498814060 on rest: a hook onError abort answers the data door with a 400 that carries no error code, and the server logs it as an unhandled SandboxError #27508 split it here (p2).

⛔ Not a claim.

Correction to my split 6498814060 (p2): a new public wire code is a protocol addition, and the standing rule is 「协议新增定 p1」. So this card is p1.
A Seam card (SKILL.md 锚定规则): the spec lane declares the ADR-0112 ledger code, and the consumer end emits it (packages/types mapDataError, packages/rest/src/error-response.ts). One claim declares both ends and runs the in-flight intersection check against the rest: a hook onError abort answers the data door with a 400 that carries no error code, and the server logs it as an unhandled SandboxError #27508 log half (server). Acceptance: the /data door answers an undeclared abort with the code, and the ledger row is live.
Clause-②: yes: the code name is the maintainer's at approval. A contract review is owed before approval. ⛔ Declared refusals keep their declared codes, and ruling 6431311681 letter A is not reopened.
enhancement, pm:queue.

Account: os-support-ai
Branch: claude/project-thread-0evlg0 (card thread; the platform assigns the thread's branch and it can push only that one, written as measured instead of claude/issue-27597-<slug>)
Worktree: objectstack-27597
Domain: domain:spec
Seat: domain:spec#3
Ruling-ref: ruling 6431311681 (#26170 letter A: hook refusals are declared by code), not reopened; triage 6500443789: one ledgered ADR-0112 code for an undeclared abort, both ends in one claim
File surface: the ADR-0112 ledger row (packages/spec/src/api/error-code-ledger.zod.ts and the wire code enums it needs), the emitter (packages/types/src/data-error-classification.ts mapDataError, packages/rest/src/error-response.ts), the client SDK's ledger-code mapping if any, their tests, one changeset per touched published package (stop on breach; explain in the report)
Container & model: M, mode:thread, model: TIER_DEFAULT — --tier: no path-derived mandate (a new public wire code; the contract review is triage's), effort: high
Clause-②: yes (widening)
Metadata-protocol: as measured by the dev under AGENTS.md's rule
Responsibility: an unclaimed p1 domain:spec card; seat 1 is off duty
Thread-read: 6500443789
Premise: to be measured first by the dev on origin/main 178b5238: a hook that aborts with free text and no declared code is answered at the /data door with a code-less 400
Serial constraints cleared: #27508's log half (domain:server) is in flight on the same door; the dev runs the in-flight intersection check against its claim and PR before editing, and leaves the log half alone

Claim amendment: one declaration, one surface addition, one seat ruling · domain:spec seat 3 · session session_01WGufzgbJhFoXYsLSe5WSPP · 2026-10-29T17:00Z · same claim 6500976762, same branch claude/project-thread-0evlg0

Metadata-protocol: none, as measured by the dev: a wire error code is not something a metadata author writes.
File surface adds the teaching and pins the new code makes false: content/docs/protocol/kernel/error-handling.mdx, the generated content/docs/references/api/*.mdx, and packages/dogfood/test/hook-error-format.dogfood.test.ts. The eleven rest suites that pinned the old answer are tests beside the emitter.
Seat ruling on the dev's open question: Clause-②: yes (widening) stands. The only accept set that moves is the published code vocabulary, which gains HOOK_ABORTED. On the nested doors that re-dress /data's classification (sharing rules, security suggested-bindings, approvals) and on the import-undo failures list, the same undeclared abort moves from the status-floor VALIDATION_ERROR to HOOK_ABORTED. That is one abort answered with one code on every door that reads the classification, not a refusal of anything a client sends. The changeset carries it as a named behaviour note so the release text shows it. No ui/** or @objectstack/client reader branches on that value for those routes (measured by the dev).

`origin/main`	contains the merge commit (`git merge-base --is-ancestor`)

Delivered:

A sandboxed hook body that aborts a write with free text, declaring no code, now answers with the ledgered code HOOK_ABORTED beside its sentence. Before, it was the one refusal on the data door a client could not branch on. A refusal that declared a code keeps it, and a crashed body is still the sanitised 500 INTERNAL_ERROR.

Owed elsewhere: none on this card. The seat chose the code name HOOK_ABORTED; a rename would be a new card. pm:dispatched is removed here; the card is closed by the merge.
