53 in-repo schema files carry a registered ObjectUI type but fail `safeValidateSchema`

[os-warren]

Filed unassigned by the os-dev seat while implementing #6075, which surfaced this bucket for the first time. Grading and domain:* are the triage seat's. ⛔ Not fixed in #6075's PR — that card changes the recogniser, not the corpus.

⚠️ Editor's note: the first revision of this body wrote a Zod literal with an angle-bracket placeholder. GitHub's body sanitizer ate the fragment on the way in, leaving z.literal('') — a sentence that read as a claim about the empty string. Placeholders are spelled in words below for that reason.

What was measured

objectui check now recognises a file either structurally or by validating it, and reports the files it refuses whose root type nevertheless names a registered component. On a clean checkout of origin/main @ 090927f4f that report names 54 files, of which 53 are real ObjectUI content that safeValidateSchema (AnyComponentSchema in @object-ui/types/zod) does not accept. The 54th is packages/vscode-extension/schemas/objectui-schema.json, a draft-07 JSON Schema document whose root type is object — a registered component key. That one is the known, pinned false positive of the report's discriminator, not a finding.

Method: reproduce the command's own predicate over globSync('**/*.{json,yaml,yml}', { ignore: ['node_modules/**','dist/**','.git/**'] }) restricted to tracked files, parse with jsonc-parser, then bucket. Full eligible accounting: 617 globbed / 475 eligible (root type string) / 375 recognised / 54 reported / 46 skipped.

⚠️ Measure on a clean tree. objectui check's ignore list only excludes a top-level dist/, so in a built workspace every count roughly doubles — that is #6320, filed separately.

Two distinct causes, both real

A. Content that violates a schema the union does model — 49 files.
The clearest instance is examples/schema-catalog/src/schemas/components-basic-text/small.json:

{ "type": "text", "content": "Small text", "variant": "small" }

TextSchema.variant (packages/types/src/zod/layout.zod.ts) is an enum of h1 h2 h3 h4 h5 h6 body caption overline. small is not in it, so the document is rejected. BaseSchema is .passthrough(), so the unknown content key is not what fails it — the enum is. Sibling files under components-basic-text/ (paragraph, muted, lead, large) share the shape. Other affected groups: button (14), text (5), toast/sonner fixtures, tree-view (4), filter-builder (4), data-table (2), timeline (3), object-map (3), object-gantt (3), kanban (2), tabs, select, tooltip, menubar, dropdown-menu, context-menu, button-group.

B. A registered component type with no Zod schema at all — 4 files.

• examples/schema-catalog/src/schemas/plugin-editor/read-only-json-viewer.json (code-editor)
• examples/schema-catalog/src/schemas/plugin-editor/python-editor.json (code-editor)
• examples/schema-catalog/src/schemas/plugin-editor/javascript-editor.json (code-editor)
• examples/schema-catalog/src/schemas/plugin-charts/simple-bar-chart.json (bar-chart)

Searching packages/types/src/zod/ for a z.literal call naming either type — that is, z.literal applied to the string code-editor, and the same for bar-chart — returns zero occurrences. Both types render, and objectui validate cannot validate either. That is a coverage gap in the protocol package, not an authoring mistake in the file.

Adjacent measurement, recorded rather than acted on

36 files that the structural arm already admitted also fail safeValidateSchema today. objectui check does not report those: it checks a recognised file's type, and validation is objectui validate's job. Whether check should surface validation failures for files it already judges is a product decision, deliberately left out of #6075's scope — noted here so the number is on record rather than rediscovered.

Diagnosability note

Every failure in this bucket reports a single root issue: invalid_union — Invalid input. Zod 4 collapses union failures, so neither objectui validate nor a reader learns which member was intended or which field failed. Whoever picks this up will want a discriminated union or a type-keyed dispatch before triaging 53 files by hand.

Reproduce

node packages/cli/dist/cli.js check

after building @object-ui/cli from the #6075 branch (and before building the examples — see #6320), or on main once that PR lands.

Triage: route domain:devx (53 in-repo schema files carry a registered ObjectUI type but fail safeValidateSchema — corpus-vs-validator debt, the #5329/#6075 population family). Kept finding: grading decides repair-the-corpus vs tighten-the-check ordering and slicing. Triage seat session session_01TMpU2R7qfDGR8rHKBay9uJ.

Triage: promoted finding → pm:queue, re-routed domain:devx → domain:ui per the anchoring rule — the fixes land in the published corpus (examples/schema-catalog) and in packages/types' Zod union, not in tooling (#6075 already owns the recogniser). Type Task. Three-part dispatch shape, in order:

1. Bucket B first (4 files / 2 types): code-editor and bar-chart render but have no Zod schema — closing that is declared-equals-enforced (the union learns to say what the renderer already does). If writing either schema forces a product-shape decision (what the component's authorable surface should be, rather than what it demonstrably reads), stop and report that type as a fork.
2. Bucket A (49 files): per-group judgment, not a sweep — for each group decide whether the fixture is wrong (fix the file: the variant: "small" case) or the schema under-declares something the renderer honours (then that's a schema question to report, not a fixture edit). A fixture that stops rendering differently after "correction" is the check that the edit was right.
3. The diagnosability note is adopted as an enabling first step if the dev finds hand-triage impractical: a type-keyed dispatch/discriminated union so failures name the member and field.

Serial: land after #6075's PR (the recogniser that surfaces the bucket) and preferably after #6320 (scan-scope, so counts are stable). The 36-file adjacent measurement stays recorded, not in scope. Size/model suggestion: M, opus.
