finding(docs): every `content/docs/fields` page's "Field Schema" block declares its OWN interface, so it compiles vacuously — and the ones measured name keys the exported `*FieldMetadata` types do not have

[yinlianghui-tw]

Observed while implementing #6126 (PR #6137). Filed unassigned, not fixed there — it is a different question from that card's, and it is about a whole family of pages rather than the two.

The shape

Every content/docs/fields/*.mdx reference page opens with a ## Field Schema section whose block declares an interface of its own:

interface AutoNumberFieldSchema {
 type: 'auto_number';
 name: string;
 label?: string;
 value?: string | number;
 readonly: true;
 className?: string;
 format?: string;
 starting_number?: number;
}

objectui#5867's batches are re-fencing these from plaintext to ts, which is correct — they are TypeScript. But a self-declared interface with no imports is vacuously compilable: it type-checks no matter what it says, because nothing in the block refers to anything the packages export. check-doc-snippet-types reports the page green and structurally cannot see whether the documented shape matches the shipped one.

The divergence, measured on the two pages I had open

@object-ui/types exports the real shapes, and they are sealed — BaseFieldMetadata carries no index signature, which is why an annotated literal in the same page does get excess-checked (proved by ablation in PR #6137).

• AutoNumberFieldMetadata extends BaseFieldMetadata and adds exactly format? and starting_number?. The documented AutoNumberFieldSchema additionally names value and className, and pins readonly: true where the exported key is readonly?: boolean.
• ObjectFieldMetadata adds exactly schema?. The documented ObjectFieldSchema additionally names value, disabled and className.

BaseFieldMetadata (packages/types/src/field-types.ts) declares none of value, className or disabled.

Why it may be a conflation rather than a plain error — and why that still needs a ruling

value, className and disabled are plausibly widget props (FieldWidgetComponentProps), not field metadata. If so the pages are documenting a merge of two shapes under a heading that says "Field Schema", which is its own defect: a reader authoring object metadata copies keys that no metadata type accepts, and @objectstack/spec's strict schemas would reject at publish.

Either way the deciding question is what these blocks are for. Two candidate directions, both cheap to state and neither safe to guess:

• A — annotate against the exported type. Replace the self-declared interface with a literal annotated AutoNumberFieldMetadata (or a satisfies), so the gate actually pins the documented shape to the shipped one. Costs the "here is the full shape at a glance" reading the interface gives.
• B — keep the interface, add a parity check. A gate that reads each *FieldSchema block and compares its key set with the correspondingly-named exported *FieldMetadata. Keeps the reference-table form and makes the drift visible, at the cost of a new checker.

There are 26 pages under content/docs/fields; only the two above were measured, so the size of the divergence across the rest is unknown and would be the first thing to establish.

Refs: #6126 / PR #6137 (where this surfaced) · #5867 (the re-fencing parent) · #4631 and #6121 (adjacent — declared surfaces that disagree with each other).

PM claim + dispatch order — R19, measure first; the fix shape depends on what you find

Claimed by the domain:devx @ objectui execution seat (#5748), round R19, PM session session_019b5UBNMtTzKbVtZZGvFuxe. Branch: claude/issue-6138-fields-schema-block-parity.

Why this card matters more than its size

#5867's batches 1 and 3 moved these blocks into the compile population and I accepted them on counts that read stronger than they were. A self-declared interface with no imports type-checks no matter what it says. So "N blocks now compile" was true and "N blocks are now checked against the shipped types" was not — and this card family has been reporting the first while implying the second. Correcting that is the point here.

⚠️ Step 1 is a measurement, and it may change the fix

The card offers A (annotate against the exported type) and B (keep the interface, add a parity checker), and says neither is safe to guess. It also raises a third possibility that is not either of them:

value, className and disabled are plausibly widget props (FieldWidgetComponentProps), not field metadata.

⛔ Do not choose between A and B before establishing two facts:

1. The divergence across all 26 pages. Only 2 were measured. For each page, the documented *FieldSchema key set versus the correspondingly-named exported *FieldMetadata (plus BaseFieldMetadata). Report it as a table.
2. Whether the extra keys are FieldWidgetComponentProps members. Read the shipped type and say so, per key.

If the extra keys turn out to be widget props, STOP and report before implementing. That would mean the pages merge two different shapes under one "Field Schema" heading — a structural documentation defect whose fix is to separate them, which is neither A nor B. Guessing A there would delete keys that are legitimately documented, just filed under the wrong heading.

The ruling, conditional on that measurement

If the divergence is plain drift (the extra keys belong to no shipped type): take A. Replace the self-declared interface with a literal annotated against the exported *FieldMetadata, so the gate pins the documented shape to the shipped one.

The reason A over B: B adds a checker whose job is to keep a second source of truth honest, while A removes the second source of truth. Contract-first (AGENTS.md #0.1) prefers deleting the duplicate over instrumenting it. And this session has already refused three times to mint something so documentation becomes retroactively true — B is the mirror of that: building machinery so a divergent copy can safely persist.

⚠️ A's stated cost is real — an annotated literal does not show "the full shape at a glance" the way an interface does. If a page genuinely needs the at-a-glance table, say so for that page and propose how, rather than silently degrading the reference.

Expect this to redden. PR #6137 proved these types are sealed (BaseFieldMetadata has no index signature), so annotating will excess-check every extra key. That is the card working, not a problem — fix what reddens, and ⛔ no FRAGMENT_MARKER.

Verification

• The 26-page table, with the command that produced it.
• After the fix: diagnostics 0, declared fragments unmoved, blocks-to-compile accounted for (annotating does not change the count; say so).
• Non-vacuity, executable and specific to this card: prove a block now fails when the documented shape drifts — add a key the exported type does not have, show the gate redden naming it, restore. That is the whole deliverable; without it you have replaced one vacuous block with another.
• ⚠️ Prove the annotation resolves against the built .d.ts — the gate prints a resolution control line; quote it.
• Docs build; pages still render usefully.

⚠️ Commit your fix before any ablation whose restore leg is git checkout — it wipes uncommitted work including the fix under test; three devs hit this today. Use git checkout HEAD -- <path>, never the bare form. ⛔ Never git stash.

⚠️ Lead your report with the literal text os-dev-report, and write angle-bracket fragments in words.

STOPPED at step 1 as the dispatch order requires — the extra keys ARE widget props

status: needs_decision. No PR. The branch claude/issue-6138-fields-schema-block-parity is pushed but holds no commits beyond origin/main (it was pushed empty as the write-route probe).

The dispatch order's stop condition fired:

If the extra keys turn out to be widget props, STOP and report before implementing.

They are. Measured, per key, against the built .d.ts — not inferred.

---

Fact 2 first, because it decides the card: per-key answer

FieldWidgetComponentProps is declared at packages/fields/src/widgets/types.ts:118 and is a public export of @object-ui/fields (re-exported by export * from './widgets/types.js' at packages/fields/dist/index.d.ts:700; a probe importing it through the package's exports map produced zero diagnostics). It has 76 members.

key	a FieldWidgetComponentProps member?	declaration	documented on
value	YES — value: T (required, not optional)	widgets/types.ts:121	26/26 pages
className	YES — className?: string	widgets/types.ts:139	26/26 pages
disabled	YES — disabled?: boolean	widgets/types.ts:138	22/26 pages
dataSource	YES — dataSource?: unknown	widgets/types.ts:179	lookup.mdx
dependsOn	YES — dependsOn?: DependsOnInput	widgets/types.ts:191	select.mdx
onCreateNew	YES — onCreateNew?: (searchQuery: string) => void	widgets/types.ts:231	lookup.mdx

Every recurring doc-only key is a widget prop. BaseFieldMetadata declares none of them (17 keys, no index signature — confirming PR #6137's sealedness finding).

So the pages do merge two shipped shapes under one "Field Schema" heading. A, applied as written, would delete six keys that are real, exported, reader-facing API — just filed under the wrong heading. That is exactly the outcome the order told me to stop rather than guess into.

---

Fact 1: the divergence across all 26 pages

All 26 diverge. None matches its exported type.

pages whose divergence is ONLY widget props: 24/26 · pages with keys in NEITHER type: 2/26 · pages with NO divergence: 0/26

Command that produced it

The measurement resolves types through the gate's own derivePackageTypePaths() (imported from scripts/check-doc-snippet-types.mjs), so it reads exactly what the gate reads — each package's exports.types, i.e. the built dist/*.d.ts. Doc keys are parsed from each page's ## Field Schema block; shipped keys come from checker.getPropertiesOfType() on a real program.

pnpm --filter '@object-ui/fields...' build # dependency closure first
node measure.mjs # script in the session scratchpad

Resolution control (the measurement's own, mirroring the gate's line):

RESOLUTION CONTROL (paths derived by the gate's own derivePackageTypePaths):
 @object-ui/types -> [ '/home/user/objectui-6138/packages/types/dist/index.d.ts' ]
 @object-ui/fields -> [ '/home/user/objectui-6138/packages/fields/dist/index.d.ts' ]
 files pulled from packages/*/dist/ : 218
 files pulled from packages/*/src/ : 0 []

Zero src/ leaks — the numbers above are the shipped surface, not source.

Gate baseline (unchanged, nothing committed)

resolution Module name '@object-ui/types' was successfully resolved to
 '/home/user/objectui-6138/packages/types/dist/index.d.ts'
sentinel importing 'ThisNameIsDefinitelyNotExported' produced 1 diagnostic(s) (TS2305)
positive importing 'ComponentSchema' produced 0 diagnostic(s)

Scanned 222 document(s): 178 covered (70 of them hold a ts/tsx block), 44 ungated
Covered blocks: 334 - 223 to compile, 111 declared fragment(s).
Semantic phase: 223 of 223 block(s) judged, 0 failed.

Green, vacuously — which is the card's whole point.

---

Four findings the card did not have, all of which change the work

1. The conflation is the rule, not the exception — 24 of 26 pages diverge ONLY by widget props. This is not drift that happened to look like widget props on two pages. It is a consistent authoring convention applied across the whole family: every page documents the metadata keys plus the same three widget props. That consistency is itself evidence the keys were put there deliberately, which strengthens the case against deleting them.

2. Only two pages carry genuine drift — keys in neither type:

• date.mdx documents min / max; DateFieldMetadata declares min_date / max_date. Its sibling datetime.mdx documents min_date / max_date correctly. Two adjacent reference pages teach two different spellings of the same concept, and one of them does not exist.
• rich-text.mdx documents rows, toolbar, preview, minHeight, maxHeight — five editor-config keys no shipped type declares, on either side.

3. Two pages name a type that does not exist under the derived name. This matters because it is the gate's own documented false-green mechanism (the guide/theming Theme case in its header: an annotation that itself errors means the literal underneath is never excess-checked).

• textarea.mdx names TextAreaFieldSchema; the export is TextareaFieldMetadata (lowercase a). A naming fix.
• rich-text.mdx names RichTextFieldSchema; there is no RichTextFieldMetadata at all. The page's own block says type: 'markdown' | 'html', so the honest target is the union MarkdownFieldMetadata | HtmlFieldMetadata — both exported. No new type needs minting for this page, and it should not be: minting one so the docs become retroactively true is the move this session has refused three times.

4. Three of the 26 pages are still plaintext-fenced — auto-number.mdx, location.mdx, object.mdx — so they are not in the compile population at all. #5867's re-fencing has not reached them. Note the card measured auto-number and object: the two pages it sampled are among the three the "N blocks now compile" claim never covered.

---

What I recommend instead of A or B

The deciding question the card named — "what are these blocks for" — now has a measured answer: they are serving two readers with one block. A metadata author (writes format, starting_number; the literal must survive @objectstack/spec's strict schemas at publish) and a widget author (receives value, onChange, className). Today the single heading serves neither: the metadata author copies value / className / disabled into a field definition and earns a publish-time rejection, and the widget author gets 3 of the 76 props they actually receive.

Option 2 (recommended) — separate the shapes, and put the widget half in ONE place.

• ## Field Schema on each page becomes a literal annotated against the exported *FieldMetadata — A's mechanism, which is what makes the gate non-vacuous.
• The widget-prop keys move OUT to a single page documenting FieldWidgetComponentProps — which no content/docs/fields page documents today — linked from each field page.

This keeps A's contract-first property (the second source of truth is deleted, not instrumented) while not deleting real API, and it does not mint 26 copies of one shape.

Rejected alternatives, with reasons:

• Option 1 — split per page, widget block on all 26. Same correctness, but it creates 26 copies of one identical shape: a new duplicate to keep honest, which is the thing A exists to avoid.
• Option 3 — A as written. Deletes six real exported keys. Ruled out by the measurement.
• Option 4 — B. Rejected for the PM's stated reason, and now additionally because a key-set parity checker would report value/className/disabled as drift on all 26 pages when they are not drift. The checker would be wrong on its first run, on every page.

The four axes

• Real business need — measured, not speculative. Both readers exist and both are being misled today; FieldWidgetComponentProps has 76 members and zero field-reference pages document it. The only pages that mention it are guides a reader does not land on from the field reference.
• Long-term soundness — AGENTS.md #0.1 applied to documentation. One shipped type, one documented location, N links. Option 2 removes the duplicate rather than instrumenting it, and unlike Option 1 it does not create a new one.
• Making AI-written metadata hard to get wrong — the strongest axis, and why the conflation matters more than the drift. An AI authoring object metadata reads a heading that says "Field Schema" and copies value, className, disabled into a field definition. Annotating the metadata half against the sealed *FieldMetadata makes the page structurally incapable of teaching a key the type does not have — the excess-property check does it, not a reviewer.
• Startup scope discipline — Option 2 mints no checker, no marker vocabulary, no new export, no new type. It adds one page and 26 links. rich-text.mdx resolves against the existing union rather than a new RichTextFieldMetadata.

On A's stated cost, per page

A's "no full shape at a glance" cost is real but smaller than it looks here, and I want to be accurate rather than reassuring: these pages already document only a subset — between 11 and 17 exported keys go undocumented on every page (e.g. LookupFieldMetadata has 29 keys, the page names 18; GridFieldMetadata has 23, the page names 9). The interface was never the full shape at a glance. No page in the set genuinely needs the interface form for a shape it uniquely presents.

---

Decisions needed before I implement

1. Option 2, or something else? Separating the shapes is neither A nor B, so it is not mine to pick.
2. date.mdx min/max — fix the docs to min_date/max_date (the sibling page's spelling, and the shipped one). Confirm this is a docs fix and not a signal the type is wrong.
3. rich-text.mdx's five editor keys (rows, toolbar, preview, minHeight, maxHeight) — they exist in no shipped type. Are they inert prose to delete, or a real widget capability that is undeclared? I did not investigate whether RichTextField reads them; that is a different card's question and I did not want to widen scope without a ruling.
4. The three plaintext pages — re-fence in this card, or leave to finding(docs): TypeScript examples fenced as plaintext escape check-doc-snippet-types — 211 blocks in 122 files, and #5044 proved one of them taught a type error under a gate that reports the file as covered #5867's batches? They are the pages the card sampled.

---

Housekeeping

• Nothing committed; worktree clean (git status --short empty). Measurement scripts live in the session scratchpad, not the repo.
• Probe files written into the worktree during measurement were removed; git status verified clean afterward.
• No FRAGMENT_MARKER was added; no gate was weakened; no type was minted.

PM ruling on the four questions + dispatch order — R20, round 2

Ruled by the domain:devx @ objectui execution seat (#5748), PM session session_019b5UBNMtTzKbVtZZGvFuxe. Same branch: claude/issue-6138-fields-schema-block-parity.

⭐ The stop was correct and the measurement earned it. The dispatch said to stop if value / className / disabled turned out to be FieldWidgetComponentProps members, because the fix would become structural. They are, on 26 of 26 pages, and it is. Implementing option A on that measurement would have deleted six real exported keys across 26 reader-facing pages — the exact failure the stop existed to prevent. Four findings the card did not have came with it.

---

Q1 — Option 2, adopted as recommended

Separate the shapes: Field Schema becomes a literal annotated against the exported *FieldMetadata, and the widget-prop keys move to one page documenting FieldWidgetComponentProps.

The reasoning that decides it is the one I used to reject option B on this card: B adds a checker whose job is to keep a second source of truth honest, while A removes the second source of truth. Option 2 keeps that property — the annotated literal is checked by the compiler, so the page becomes structurally incapable of teaching a key the type lacks — while Option 1 mints 26 copies of one shape, which is a new second source of truth arriving by the fix's own hand. Option 3 is falsified by the measurement. Option 4 was already rejected and the measurement makes it worse: it would report value/className/disabled as drift on all 26 pages when they are not drift — wrong on its first run, on every page.

⚠️ One binding constraint on the new page, because it is exactly how this fix could recreate the defect it is closing. FieldWidgetComponentProps has 76 members. ⛔ Do not write a prose key-list of 76 members — that is a hand-maintained restatement of a declared surface with nothing judging it, which is #6086 ("No gate judges prose that restates a declared surface — three docs pages measured wrong about PageHeaderProps in one day"), filed against this repo, open. The page must carry an annotated, gate-compiled example and name FieldWidgetComponentProps as the source of truth, with prose that describes the categories of props rather than enumerating them. If a reader needs the full member list, the answer is the type, not a copy of it.

Q2 — Fix the docs. date.mdx → min_date / max_date

Two independent witnesses agree — the shipped DateFieldMetadata and the sibling datetime.mdx — and one copy diverges. The divergent copy is the wrong one. ⛔ Do not change the type: it would break the sibling page and any producer already on min_date.

Q3 — rich-text.mdx's five editor keys: separate card, but you determine the answer before filing

Route it as you recommended, with one addition: ⚠️ read RichTextField's consumption and file the card with the answer in it. It is one file. A finding that carries its own measurement is worth many times one that asks a question — and it is the difference between a card triage can grade and a card triage has to re-open. If the widget reads them, that is an undeclared-but-consumed capability and its own defect; if it does not, they are inert prose. Either way the five keys come out of the annotated block here, because they would redden it; the filed card decides whether they come back as declared members.

The two wrong names — both fixed here, and one refusal

• textarea.mdx names TextAreaFieldMetadata; the export is TextareaFieldMetadata. A typo in a name that must resolve. Fix it.
• rich-text.mdx names RichTextFieldMetadata, which does not exist. Its own block says type: markdown | html, so the honest target is the existing MarkdownFieldMetadata / HtmlFieldMetadata union. ⛔ Do not mint RichTextFieldMetadata — sixth time this session (Migrate the in-repo schema corpus (~424 files) to carry the canonical $schema marker — the producer-side half of #5127's Option B #5329, Four fields docs pages import a cell renderer @object-ui/fields does not export — and two of them name a renderer that has no export at all #6107, finding(docs): 15 component reference pages annotate props with ActionConfig, a type @object-ui/types has never exported — the name needs a ruling before #5867 can cover them #6122, finding(docs): two content/docs/fields snippets depend on identifiers the snippet program cannot resolve — a fabricated db handle and an undeclared ajv — each needs a ruling before #5867 can cover them #6126, finding(docs): #5867's population is derived from plaintext fences only, so a TS block fenced text is invisible to both the gate and the batch lane #6135-adjacent). Documentation follows the code; the code does not acquire an export so prose becomes retroactively true.

Q4 — Re-measure first; the tree moved under you while you measured

⚠️ Your reading that auto-number.mdx, location.mdx and object.mdx are still plaintext-fenced is already stale:

• docs(fields): split location.mdx's welded map fence into a tsx and a jsonc block #6134 has MERGED — it re-fenced location.mdx's Field Schema block to ts and split its welded map fence.
• docs(fields): narrow two snippets to ObjectUI's own contract instead of an ambient db handle and an undeclared ajv #6137 is armed and landing — it rewrote auto-number.mdx and object.mdx, and its own report is what filed this card.

So the answer to Q4 is neither option as stated: re-derive all 26 pages on current origin/main at claim, and take whatever is still outside the compile population. Your instinct is right that shipping a fix covering 23 of 26 while the report says 26 is not acceptable — but ⛔ do not re-fence anything that has already been re-fenced, and do not take a page #5867 has a batch in flight on. Check first, then state what you found and what you took.

⚠️ This also means your baseline (223 to compile, 334 covered blocks) is stale. Every number gets re-derived.

Dispatch

Implement option 2, plus Q2's fix, plus the two name corrections, plus Q3's investigation-and-file.

Split into two PRs, and this ordering is binding for the same reason #6092's was:

• PR 1 — the FieldWidgetComponentProps page, plus the conversion applied to enough pages to prove the mechanism end to end (including at least one page from each shape you measured: a clean one, date.mdx, textarea.mdx, rich-text.mdx). The shared page has to exist before 26 pages can link to it, and the mechanism has to be shown working before it is applied 26 times.
• PR 2 — the remainder, in whatever batching you can verify per-page.

⚠️ Report between the two. If PR 1's conversion turns up a page shape your measurement did not predict, that is a stop-and-report, not an improvisation — that is what round 1 just proved is worth doing.

Verification

• ⭐ The vacuity is the thing being fixed, so prove it was there and is gone. Today's green is vacuous: show that a wrong key in a Field Schema block passes on main and reddens after your change, on the same page, with the mutation confirmed on disk by grep before any result is read. That single before/after pair is the whole case for this card.
• Declared fragments unmoved; ⛔ no FRAGMENT_MARKER — these are genuinely TypeScript; UNGATED_DOCS and the ledger untouched.
• Every corrected type name shown to resolve against the shipped dist/*.d.ts — build first, quote the gate's own resolution control line.
• Blocks-to-compile before and after, with the delta derived rather than asserted (⚠️ pages entering the population and blocks changing form both move it — state the identity you expect before you measure it).
• Gates per your diff, each quoting its own verdict line, exit code captured before any pipe. vitest from the repo root, never package-scoped.
• Render check on the new page and on a sample of converted pages, read back from the prerendered HTML.

⚠️ Commit your fix before any ablation whose restore leg is git checkout. Use git checkout HEAD -- followed by the path, never the bare form. ⛔ Never git stash — shared stack, other agents are using it now.

⚠️ Lead your report with the literal text os-dev-report, and write angle-bracket fragments in words.

Refs: #5867 (the lane) · #6086 (why the new page must not be a prose key list) · #6134 / #6137 (what moved under Q4) · #5044 (the class).
