fix(types,docs): AutoNumberFieldMetadata declares the spec's autonumberFormat, and the auto-number page teaches it (objectui#12282)

[objectstack-fleet]

Fixes #12282

Clause-②: yes

AutoNumberFieldMetadata (@object-ui/types) declares autonumberFormat, typed by reference to @objectstack/spec's FieldSchema.autonumberFormat, and keeps format as the shorthand. The auto-number docs page teaches autonumberFormat for a new field and format as the shorthand, and says which one wins.

What changed

• packages/types/src/field-types.ts, AutoNumberFieldMetadata only.
  • New member autonumberFormat?: SpecField['autonumberFormat'], in the file's existing by-reference idiom (import type { Field as SpecField } from '@objectstack/spec/data').
  • Its docblock states the spec's precedence: a non-empty autonumberFormat, then a non-empty format, then the contract default {0000}. That is what resolveAutonumberFormat (@objectstack/spec/data) does.
  • format?: string stays, with a new docblock calling it the shorthand.
  • The starting_number tombstone's docblock now says the number is minted from autonumberFormat or its shorthand format.
• content/docs/fields/auto-number.mdx.
  • Both typed literals (invoiceNumber, orderNumber) carry autonumberFormat.
  • One new paragraph under the first literal teaches format as the older shorthand (format: 'INV-{0000}'). It also says autonumberFormat wins when a field sets both.
  • The nine Format Templates lines change their key from format: to autonumberFormat:. Every pattern and its comment is unchanged: the nine pattern and comment pairs were compared by script before and after, and they are equal.
  • PR objectui#12280's token list (Format Placeholders) and renderer text (Backend Implementation) are untouched.
• New pin packages/types/src/__tests__/autonumber-format-declared-12282.test.ts.
  • Type half, read by type-check through tsconfig.test.json: the member equals SpecField['autonumberFormat']. Fresh literals carrying autonumberFormat, format (the control) and both keys compile.
  • Runtime half, against the installed spec: FieldSchema.safeParse accepts all three literals, behind a control that refuses an undeclared key by name. resolveAutonumberFormat returns autonumberFormat when both keys are set, and format when it is alone.
  • The objectui#12242 pin file is not edited.
• .changeset/12282-types-autonumber-format.md: @object-ui/types, minor.

Premises checked against main before the edit

• AutoNumberFieldMetadata declared type: 'autonumber', format?: string and starting_number?: never, and no autonumberFormat.
• The installed @objectstack/spec is 17.7.0. Its FieldSchema declares autonumberFormat: z.string().optional(). Its format describe calls format "the shorthand that predates autonumberFormat, which wins when both are present".
• resolveAutonumberFormat takes a non-empty autonumberFormat, then a non-empty format, then {0000}. Probed: { autonumberFormat: 'A-{0000}', format: 'F-{0000}' } gives A-{0000}, and { autonumberFormat: '', format: 'F' } gives F.
• The spec's own field forms offer autonumberFormat when type == 'autonumber'. app-shell's predicate.test.ts lists it among the Studio sub-fields.

Clause-② reading: the built .d.ts, base vs head

I measured this with the TypeScript compiler API on packages/types/dist, built at base 5d3f437a (the main tip this branch merges) and at head aae05a1a:

• Export closure: unchanged. All 12 exports entries resolve and export the same names: 1222 entry and name pairs, the same set at base and head. The same reading at the original base, 45ae6b89 against e9325f4c, gave the same result.
• AutoNumberFieldMetadata members: exactly one is added, autonumberFormat?: string | undefined. No member is removed or retyped.

Reverse check (one-off, no permanent test file)

I started from the committed implementation (e9325f4c). objectstack's scripts/ablation-replace.mjs deleted the declaration line autonumberFormat?: SpecField['autonumberFormat'];: the anchor hit once and went from 1 to 0, and the blob went from a067fe16 to 19c4a973. The tool held the mutation while these legs ran:

• tsc -p tsconfig.test.json (the type-check test leg): exit 2. TS2353 on both fresh literals that carry autonumberFormat, and TS2339 on the by-reference assertion and the two runtime reads.
• check:doc-snippets: I rebuilt @object-ui/types with the mutation, and the declaration count in dist/field-types.d.ts read 0. The gate then exited 1: 789 of 789 blocks judged, 2 failed. Both failures are the typed literals on content/docs/fields/auto-number.mdx, with TS2353.
• The pin's vitest half stayed green (5 passed). That is the expected direction: it reads the installed spec, not the type.
• Restore: the blob equals HEAD, git diff HEAD is empty, and git status --porcelain is empty. I rebuilt the package from HEAD, and the declaration count in dist read 1 again.

Gates (all on head aae05a1a, after merging origin/main, which includes PR objectui#12293)

• The check:doc-snippets --build-filter closure (34 filters, which includes @object-ui/types), built with turbo run build --concurrency=2 under the shared verify lock: 35 of 35 tasks, VERDICT command-exit 0.
• pnpm --filter @object-ui/types type-check, which echoed tsc --noEmit && tsc -p tsconfig.examples.json && tsc -p tsconfig.test.json: exit 0. The new pin is in the tsconfig.test.json program (--listFilesOnly).
• pnpm exec vitest run packages/types/: 374 files, 10237 tests passed. The new pin run alone: 5 passed.
• pnpm check:doc-snippets: exit 0, "Semantic phase: 790 of 790 block(s) judged, 0 failed."
• pnpm check:doc-examples: exit 0, "Every covered @example compiles, or fails exactly as its ledger row declares."
• node scripts/check-doc-links.mjs: exit 0, "Links are valid across 17 scan roots."
• Each exited 0:
  • check:doc-fences, check:doc-types, check:doc-json, check:doc-example-ids
  • check:readme-exports, check:spec-symbols
  • check:changeset-claims, check:pending-changeset-literals, node scripts/check-changeset-fixed.mjs, node scripts/check-changeset-presence.mjs (1 changeset declared for 1 released package)
  • check:control-bytes
  • check:new-line-citations: "0 new citation(s)"
  • type-check:coverage, check:test-path-roots
• pnpm exec vitest run scripts/__tests__/: 187 files passed and 2 skipped; 5632 tests passed and 2 skipped; VERDICT command-exit 0.
• node scripts/check-governed-queue-guard.mjs --test on the four changed paths: NOT GOVERNED.
• ESLint, narrowed to the touched package and shown to exclude nothing:
  1. Population, from eslint's own configuration: CI's pnpm lint is turbo run lint, and @object-ui/types' lint script is eslint . against the root eslint.config.js. I ran that same eslint . in packages/types.
  2. Count, from --format json: 455 files, 0 errors. field-types.ts has 3 no-explicit-any warnings, the same 3 as at base. The new pin has none.
  3. Invariance: eslint.config.js sets no parserOptions.project or projectService, so type-aware linting is not enabled. This diff therefore cannot move the verdict on any file it does not touch. The .mdx and .md files fall outside eslint's **/*.{ts,tsx} rule blocks.

Acceptance notes

• PR objectui#12293 (objectui#12242) landed in main during this run and is merged into this branch. Its diff and this one touch disjoint interfaces in field-types.ts. It adds no member-level census over AutoNumberFieldMetadata, so autonumberFormat owes no row there.
• strict-face-read-keys-11070.test.ts records keys that a registered renderer reads on form.fields[] entries. No renderer reads autonumberFormat: the backend mints the value, and AutoNumberField prints it as stored. So it is not added there.
• The @object-ui/types README lists no AutoNumberFieldMetadata keys, so it is unchanged.
• resolveCellRendererType (@object-ui/fields) reads a field's format generically, but only acts on textual base types. So format never changes how an autonumber cell draws. Noted, not a finding.

Contract review

Served-tier: CONTRACT_REVIEW_TIER
Head-sha: aae05a1ad64768014b24888b05f038233145019c
Local-runs: none

Read at 2026-10-13T03:34Z · PR objectui#12298 (draft, base main, head repo = base repo, 4 files, +144/−15) against card objectui#12282 · triage 6135734642 · serial note 6135879674 · claim 6136988134 · dev report 6137456997. Inputs: the card body and all 4 comments, the PR body, its 4-file list, the net diff against main (5d3f437a) at the head, and the head's check-runs. The head is a merge of main (which brought PR objectui#12293) onto the implementation commit e9325f4c; the net diff against main was judged (236 diff lines, byte-identical between the API's diff and a fetch of the branch), not the merge commit. The spec premises were read at the @objectstack/spec 17.7.0 version commit in the sibling checkout, which is the version packages/types/package.json and the lockfile resolve on this head. Nothing was built, run or re-run.

① Derived judgments

Every accept-set and public-surface change the diff implies, each judged:

1. AutoNumberFieldMetadata gains autonumberFormat?: SpecField['autonumberFormat'] — RIGHT. The spec's FieldSchema at 17.7.0 declares autonumberFormat: z.string().optional(), with the contract default {0000} as a JSON-Schema annotation rather than a parse-time default, and Field is the z.input of FieldSchema, so the member resolves to string | undefined and tracks the spec by reference (objectui AGENTS.md #0.1: declare a key the spec owns by reference, not by retyping) in the file's existing import type { Field as SpecField } from '@objectstack/spec/data' idiom. The widening is the one the card asked for: a fresh typed literal carrying autonumberFormat now compiles where it failed TS2353. The new pin autonumber-format-declared-12282.test.ts holds both halves: the Equal assertion of AutoNumberFieldMetadata['autonumberFormat'] against SpecField['autonumberFormat'] is compiled by the package's type-check through tsconfig.test.json (its include is src/**/*.test.ts, which this file matches), and the runtime half parses the three fresh literals through the installed FieldSchema behind a control that refuses an undeclared key by name.

2. format?: string stays — RIGHT. Triage 6135734642 answered the card's own question (⛔ format is not retired: dropping it would make the type refuse a key the spec accepts). The spec's format describe at 17.7.0 says what the new docblock says: on an autonumber field it is the record-number pattern, the shorthand that predates autonumberFormat, which wins when both are present; prefer autonumberFormat on a new field. The member's type did not move (pinned Equal to string | undefined); only its docblock was written. Observation, not a finding: format stays a bare string rather than SpecField['format']; the two are the same type today, and the card scoped autonumberFormat only.

3. The precedence stated in the docblocks, the page and the changeset — RIGHT. resolveAutonumberFormat at 17.7.0 takes a non-empty string autonumberFormat, then a non-empty string format, then DEFAULT_AUTONUMBER_FORMAT ({0000}), and @objectstack/spec/data exports it (export * from './autonumber-format'). The pin re-derives "wins when both" and "format is read only without it" on the installed spec on every run rather than asserting it in prose (完善设计器的每一个细节 #9).

4. No other public-surface or accept-set change — RIGHT. field-types.ts adds no export; the starting_number?: never tombstone changes docblock only; the barrel packages/types/src/index.ts is untouched. The new test file's exports publish nothing: the build program excludes tests and tsconfig.test.json is noEmit. objectui has no zod face that enumerates AutoNumberFieldMetadata's keys — a form.fields[] entry parses through the spec's own FieldSchema, which already accepts autonumberFormat, so StrictAnyComponentSchema is asked no new question and strict-face-read-keys-11070.test.ts owes no row: no registered renderer reads the key (AutoNumberField prints the stored value; resolveCellRendererType reads format only when the base type is in TEXTUAL_BASE_TYPES, which autonumber is not). The dev's compiler-API reading of the built .d.ts (export closure unchanged, exactly one member added) agrees with the diff.

5. content/docs/fields/auto-number.mdx — RIGHT. Both typed literals and the nine plaintext Format Templates lines carry autonumberFormat; one new paragraph teaches format as the older shorthand and says autonumberFormat wins when a field sets both — the spec's own sentence. Checked line by line against the diff: the nine pattern-and-comment pairs are unchanged, only the key moved; the Format Placeholders token list and the Backend Implementation text from PR objectui#12280 are untouched; the Field Schema prose now names the key. The two ts blocks are compiled against the built @object-ui/types by check:doc-snippets, which runs inside Repo Gates (success on this head). The three schema-catalog examples the page embeds are renderer forms carrying no format key and are untouched.

6. Scope — inside the claim's file surface — RIGHT. The four files are exactly the claim's declared surface (AutoNumberFieldMetadata only in field-types.ts, the page, one new pin that is not field-metadata-family-retired-12242.test.ts, the changeset); the @object-ui/types README lists no AutoNumberFieldMetadata keys, so leaving it alone is right. No content/docs/releases/ or CHANGELOG.md edit; no governed path (Governed Surface Queue Guard success). Fixes #12282 on the first line is right: triage's direction — the type declares, the page teaches both and says which wins, the pins, the changeset — is delivered whole, so the card closes with the merge.

② Semver level

• .changeset/12282-types-autonumber-format.md declares '@object-ui/types': minor — RIGHT. A member is added to a published type of a released package (@object-ui/types is not private); patch would understate a widened authoring face; objectui's fixed group never declares major (Changeset Bump Policy success). The only released package whose source changed is @object-ui/types (Changeset Declaration success: one changeset declared for one released package); content/docs/** is no published package.
• Clause-②: yes on the PR body (its own line, at line start) and on claim 6136988134 — RIGHT: the diff widens the published authoring face with a new optional member, no narrowing arm. yes takes at least minor, and minor is what the changeset declares. The changeset body carries the same marker, as this repository's other pending changesets do; no ADR-0087 disposition is owed because nothing is removed or renamed.
• The changeset body names the shape before and after, says format is not retired and which key wins, and names the pin; it carries no model identifier and no line address (Line Citation Gate success: 0 new citations).

③ Boundary flags

open_questions: [] and out_of_scope_findings: [] in report 6137456997. Its five deviations, each answered:

1. Reverse check, dist leg proven by a hand count (the declaration in dist/field-types.d.ts counted 0 mutated, 1 restored) rather than by scripts/ablation-dist-preflight.mjs, which roots at the objectstack checkout — ACCEPTED. The mutation and the restore went through ablation-replace.mjs with blob hashes on both sides (a067fe16 → 19c4a973 → a067fe16, git status --porcelain empty); the two legs that read the type went red (TS2353 ×2 and TS2339 ×3 under tsc -p tsconfig.test.json; check:doc-snippets 2 of 789 failed, both the page's typed literals) and the leg that reads the installed spec stayed green, which is the expected direction. The reversal shows the pin and the page would both catch the declaration's removal.
2. Attribution: commits carry the model-free trailer pair and the PR body ends with the session-URL footer — ACCEPTED, read on both branch commits (e9325f4c, aae05a1a): a Claude-Session: URL line and a Co-authored-by: Claude line with the noreply address, no model identifier anywhere. That is what objectui AGENTS.md and objectstack AGENTS.md both prescribe, and the harness reminder yields to them.
3. The merge commit's default message amended locally before its first push — ACCEPTED; no pushed history was rewritten (the branch's pushed commits are the implementation and the merge, and both read as described).
4. Scope call: the nine plaintext Format Templates lines moved to autonumberFormat, not only the two typed literals the route named — ACCEPTED, inside the claimed file surface and inside triage's direction ("teaches autonumberFormat as the spelling for a new field"). A page that taught the shorthand on nine lines and the preferred key on two would teach two spellings of one setting, which is the defect the card names.
5. The docblock and changeset say the spec's field form, which Studio's field designer renders, OFFERS autonumberFormat, not that Studio WRITES it; the live designer was not driven — ACCEPTED, and the narrower sentence is the right one (完善设计器的每一个细节 #9): the card's "Studio writes it" rested on the predicate.test.ts and SchemaForm.unresolvedPredicate.test.tsx pins, which show the form offers the key under type == 'autonumber', exactly what the text now claims.

No flag is escalated.

Check-runs on the head

33 check-runs on this head, every one completed by the time of this write: 30 success, 3 skipped (dependabot, Test (coverage) and the coverage-shard matrix placeholder, none of which runs on a pull request), 0 failures, 0 still running. The gate-carrying contexts read success: Type Check, Lint, Repo Gates, Test and its twelve shards, Test (dist pins), Build & E2E, Build Docs, Spec Main Shape Gate, Governed Surface Queue Guard, Line Citation Gate, the five changeset gates (Changeset Declaration, Changeset Bump Policy, Changeset Fixed Group Check, Changeset Overwrite Report, Changeset Claim Re-read), Bundle Analysis, Live E2E (informational) and label. When this review began, Type Check, Spec Main Shape Gate, Repo Gates, Bundle Analysis and the test shards were still in_progress; each was read again until it completed (the last to finish was Spec Main Shape Gate), and nothing was re-run. The needs:contract-review marker is not on the PR (labels: documentation, package: types, tests), so there is nothing to remove with this record.
