Measure the strict authoring face before building it: run catalog fixtures, docs `json` fences and apps through strict node schemas and count undeclared keys per component (first deliverable of the #5250 ruling)

[os-warren]

Filed by the director seat from the #5250 ruling (maintainer, 2026-09-04, decision batch #25: option 2 — a strict authoring face as a programme, measurement first). This card is the measurement. ⛔ It builds nothing that ships: no schema in packages/types changes, no gate is wired, .passthrough() on the rendering face is not touched.

Deliverable: a number per component, not a fix

Derive, in a throwaway (a script under scripts/ or a one-off test that is not left in the tree unless the seat decides it is worth keeping as the future gate's skeleton), a strict variant of every node schema in @object-ui/types/zod — the same declared members, unknown keys refused — and run three corpora through it:

1. every fixture under examples/schema-catalog/src/schemas/**/*.json;
2. every ```json fence under content/docs/** that parses as a node document (a fence that is a deliberate fragment is counted separately as "fragment", ⛔ not silently skipped — the fragment-marking question finding: no gate reads a doc snippet's schema KEYS against the spec — #4823's deferred "second dimension", closed unbuilt #5138 already costed is part of what this measurement prices);
3. the authored documents under apps/** and packages/*/examples/**.

Report, in the PR or on this card:

• per component type: number of documents, number refused strictly, and the undeclared keys with their occurrence counts (this is the list that becomes the declaration-repair worklist in 24 catalog entries fail safeValidateSchema because the Zod mirror names a key its renderer never reads (8 components) #6939's shape — a key the renderer reads but the schema does not declare — versus the retirement worklist in finding(components): button-group implements no selection, and never wires the per-button onClick / disabled it declares — the catalog authors 29 keys nothing reads #7077's shape — a key nothing reads);
• per corpus: totals and the fragment count for docs;
• the top-level unknown keys that come from BaseSchema's own tolerance versus nested unknown keys inside declared members (the TS index signature at packages/types/src/base.ts lines 409 / 441 is the twin of the zod .passthrough(); both faces are measured, the TS side by the probe shape recorded on finding: JSON doc snippets are checked by nothing — the ts/tsx gate cannot see them, and BaseSchema.passthrough() makes objectui validate accept arbitrary undeclared keys #5250 comments 5521873763 / 5523535054).

A component with zero undeclared keys is a result too — the programme needs to know how much of the tree is already strict-clean.

Why a measurement card exists at all

The ruling on #5250 is a multi-week programme touching every node schema and AGENTS.md #0.1. Its appetite cannot be set without knowing how red strict goes on today's corpus, and which side of each red is wrong (schema under-declares, or corpus authors garbage). This card produces that reading; the programme cards (strict face on the spec side, validate + fence gate on the devx side) are priced from it on #5250 afterwards.

Constraints

• ⛔ Do not repair anything you find — file it (dedupe first; 24 catalog entries fail safeValidateSchema because the Zod mirror names a key its renderer never reads (8 components) #6939, finding(components): button-group implements no selection, and never wires the per-button onClick / disabled it declares — the catalog authors 29 keys nothing reads #7077, ChartSchema declares neither chart-level data nor xAxisKey — yet its own JSDoc teaches both, so the corrected chart model documents keys only BaseSchema's index signature admits #7549, finding(examples): a catalog menu item authors variant: "destructive", a key no arm of MenuItem declares and no menu renderer reads — but the repair has a real fork #7101 already carry several of the likely hits) or list it in the report. A measurement that fixes as it goes stops being a measurement.
• ⛔ Do not flip .passthrough() on BaseSchemaCore; it is load-bearing for renderer props (see the specFieldsExcept docblock).
• The throwaway must be reproducible: pin the main SHA it ran against and keep the script in the PR (or attach it to this card) so the numbers can be re-derived after the declaration repairs land.
• Clause-②: no (no published surface moves). pm:queue and domain:devx set by the filing seat from the ruling's named executor; triage corrects if the landing point disagrees.

File surface: a throwaway measurement script under scripts/ (or scripts/__tests__/) + the report on this card / in the PR body; ⛔ nothing under packages/types/src/**, no gate wiring, no .passthrough() change (stop on breach; explain in the report)
Container & model: M, measurement (judgment in corpus classification; nothing ships), mode:subagent, model: opus — objectstack's node scripts/pm/dispatch-gates.mjs --tier REFUSES --repo objectstack-ai/objectui (measured this round: gate families are a property of the tree it runs in), so the tier is the PM's per-card judgment under the script's declared policy floor sonnet · default opus · ceiling fable; no path-derived mandate applies to this surface.
Clause-②: no
Serial constraints cleared: none on files — the deliverable is a throwaway under scripts/ (new file) plus a report; ⚠️ #6939 (domain:spec, in flight, declaration repairs in the Zod mirror) moves the very numbers this card measures — the run pins its main SHA so it can be re-derived after #6939 lands; #5250 is pm:blocked on this card (fan-out 1)
