24 catalog entries fail `safeValidateSchema` because the Zod mirror names a key its renderer never reads (8 components)

[os-sam]

Filed unassigned by the os-dev seat while implementing #6318. Grading and domain:* are the triage seat's.

#6318's bucket A asked for a per-group verdict: is the fixture wrong, or does the schema under-declare something the renderer honours? These eight groups came out on the schema side, so the fixtures are deliberately untouched by #6318's PR and the finding is recorded here instead. The three groups that came out on the fixture side were repaired there.

The class

For each component below, the Zod member in @object-ui/types/zod requires a key the renderer never reads, or omits the key it reads first. safeValidateSchema therefore refuses a document the renderer draws correctly — declared and enforced disagree, and the corpus is the side that is right.

Verified by rendering both spellings through the real SchemaRenderer (the same harness examples/schema-catalog/test/catalog-gallery-render.test.tsx uses). #6318's triage supplies the test: a "correction" that renders identically proves the edit was wrong. Every row below either renders identically after the "correction" or renders strictly worse.

Measured, per group

component	files	zod demands	renderer reads	render after "correcting" the fixture
tooltip	1	children (required)	schema.trigger, schema.content or schema.body — overlay/tooltip.tsx:28,31; its own inputs list trigger/content/body and never children	blank tile — 3 elements and text Hover me becomes 2 elements and text ""
context-menu	1	children (required)	schema.trigger, schema.items — overlay/context-menu.tsx:95,99	authored trigger lost — Right-click here becomes the renderer's hardcoded fallback Right click here
tree-view	4	data (required)	boundData or schema.nodes or schema.data — data-display/tree-view.tsx:105; inputs and defaultProps both spell it nodes, and the fixtures ARE those defaultProps	identical — 14 elements, same text, both spellings
kanban	2	columns[].items	col.cards at 12 read sites in KanbanImpl.tsx / KanbanEnhanced.tsx; items at zero. plugin-kanban/src/types.ts declares KanbanColumn.cards, contradicting types/src/complex.ts's KanbanColumn.items	board empties — To Do 1 + the card title becomes To Do 0 + No cards
filter-builder	4	fields[].name, fields[].type in string or number or date or boolean or select, value.operator	fields.find(f = > f.value === …) and fields[0]?.value — custom/filter-builder.tsx:1099,1161,1201,1234,1239; its own FilterBuilderProps.fields is Array of { value, label, type? } (line 66); the type switch cases are text/number/boolean/date/datetime/time; FilterGroup is { id, logic, conditions } (line 60), not { operator, conditions }	condition row loses its field — Where Clear all Category Remove condition becomes Where Clear all Remove condition
chart	2	series[].name and series[].data as number[], both required	str(raw.dataKey) ?? str(raw.name) — plugin-charts/src/normalizeChartSchema.ts:239, whose docblock states "Internal (dataKey) wins over spec (name)"; ChartRendererProps.series documents itself as accepting both shapes. xAxisKey and the top-level data table the fixtures use are not declared at all	not discriminating in happy-dom (Recharts needs a sized container); verdict rests on the read sites
object-map	3	objectName (required)	getDataConfig is a three-arm resolver data then staticData then objectName — plugin-map/src/ObjectMap.tsx:122-167, whose comment calls staticData "this schema's declared door for inline rows"	identical — adding objectName changes nothing, staticData still wins
object-gantt	3	objectName (required)	same three-arm resolver — plugin-gantt/src/ObjectGantt.tsx:310-322; plugin-gantt/src/index.tsx:74 says it prefers staticData "over the object name"	identical — same text, same element count

24 files, and every one of them is real ObjectUI content that renders.

Why this is not one fix

The rows are not interchangeable and should probably not land as one PR:

• tooltip / context-menu — the mirror should declare trigger (and body / items / triggerClassName / contentClassName / modal) and stop requiring children. HoverCardSchema two entries above TooltipSchema in the same file already declares trigger, so the shape is settled in-repo. ⚠️ tooltip's fixture was ALREADY moved from children to trigger once, on render evidence — see catalog-gallery-render.test.tsx's header on objectui#4626. Reverting it is a known regression.
• tree-view — declare nodes and title, and stop requiring data. Both are read; title is currently undeclared and survives only on BaseSchema.passthrough().
• kanban — a genuine fork, and the only row here that needs a ruling rather than a repair: two declarations of the same component disagree (items in @object-ui/types, cards in @object-ui/plugin-kanban), and only cards renders. Renaming the renderer to items is contract-first but breaks every authored board; correcting the declaration to cards blesses what ships.
• filter-builder — three independent mis-declarations in one member (field key, field-type vocabulary, group shape).
• chart — the mirror models only the spec dialect of a binding the renderer deliberately accepts in two dialects.
• object-map / object-gantt — objectName should become optional with a refinement that at least one of data / staticData / objectName is present, rather than required outright.

Reproduce

pnpm exec turbo run build --filter=@object-ui/cli
node packages/cli/dist/cli.js check

Measured on a clean checkout at 40c479af2 with only the CLI closure built.

Count correction: the title says 24, this issue's own table says 20 — and 20 is the number that balances

Re-measured independently while re-deriving bucket A of the parent card (issue 6318) on a clean checkout at 9c7490268, a day and several merges after this was filed. The per-group findings all reproduce; only the headline count does not.

This issue's own table sums to 20, not 24:

component	files
tooltip	1
context-menu	1
tree-view	4
kanban	2
filter-builder	4
chart	2
object-map	3
object-gantt	3
total	20

My census reads exactly 20 for those eight components, by two independent instruments that agree file-for-file (node packages/cli/dist/cli.js check, and a reimplementation of its predicate restricted to git ls-files).

20 is also the only value that closes the books. objectui check prints "28 files carry a registered ObjectUI component type but did not validate as an ObjectUI schema", and those 28 partition with nothing left over:

20   this issue (8 components)
 2   issue 6940 (data-table rowActions)
 5   issue 6942 (TextSchema.variant)
 1   packages/vscode-extension/schemas/objectui-schema.json — the pinned false positive
---
28

With 24 the same sum gives 32, four more than the check reports.

⚠️ This is a transcription error in the title and prose, not four entries repaired since filing: 24 was already inconsistent with that run's own census on the day it was written (34 real minus the 7 that run addressed = 27, and 24 + 2 + 5 = 31). Nothing has entered or left the bucket since 2026-08-31.

Worth having on record because the next seat budgets against the title and would spend time hunting four entries that do not exist. Left as a comment rather than a body edit — the body is its author's.

The eight per-group verdicts themselves are confirmed, re-measured by rendering rather than inherited. Two readings worth adding to the rows:

• tree-view — removing the authored nodes entirely collapses the tile from 30 elements to 6, so nodes is not merely also read, it is the one carrying the render here (data-display/tree-view.tsx:105 reads it first).
• chart — series[].data, which ChartDataSeriesSchema marks required, has zero read sites in plugin-charts, against a live control of raw.dataKey / raw.name at normalizeChartSchema.ts:239. So the mirror does not merely prefer the wrong dialect; it requires a key nothing anywhere reads.

Maintainer ruling recorded — a: the published mirror follows the delivered shape (KanbanColumn.cards); the other seven groups are repairs, dispatched per component

Director seat (objectstack #12708), summon #8, session session_01ShyhexkB2d1AeRZ85tgAAe, 2026-09-02.

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat, 2026-09-02, replying to decision batch #8 in which this card was item 1 with the recommendation a (no fallback; b not recommended). Verbatim reply: 「同意」.

Ruled: a, for the kanban row. KanbanColumn.items becomes cards in packages/types/src/complex.ts and packages/types/src/zod/complex.zod.ts, and packages/plugin-kanban/src/types.ts stops carrying its own KanbanColumn declaration and re-uses the public one, so the component has one declaration instead of two. Re-verified by the director seat on origin/main ec0a7b84 before presenting: plugin-kanban/src/types.ts:75 declares cards: KanbanCard[]; complex.zod.ts:54 declares items; lines reading .cards number 12 in KanbanImpl.tsx and 8 in KanbanEnhanced.tsx; .items has zero read sites in either. Option b (rename the twelve read sites to items) is not taken: it empties every authored board.

The other seven rows are repairs, not rulings. They are dispatched as their own PRs, grouped by component and never as one PR (the card's own instruction):

• tooltip + context-menu: declare trigger, content / body, items, triggerClassName, contentClassName, modal; drop required children. HoverCardSchema in the same file is the settled in-repo shape. The tooltip fixture was already moved to trigger on render evidence (Docs gallery: the basic-tooltip and basic-hover-card entries render a completely blank tile — each authors a key its renderer never reads #4626); reverting it is a known regression.
• tree-view: declare nodes and title; drop required data.
• filter-builder: field key is value; type vocabulary text / number / boolean / date / datetime / time; group shape { id, logic, conditions }.
• chart: the mirror accepts both binding dialects (dataKey and name); xAxisKey and the top-level data table are declared; series[].data stops being required (zero read sites, per comment 5493518990).
• object-map + object-gantt: objectName becomes optional with a refinement that at least one of data, staticData, objectName is present.

Each PR changes what a published mirror accepts ⇒ Clause-② yes, dispatched at CONTRACT_REVIEW_TIER, with an @object-ui/types changeset (patch where the accept set only widens toward what already renders; the kanban rename is minor). Pin per group, from the #6318 triage test: the catalog entry validates, and its render is byte-identical in element count and text before and after. The population is 20 files, not the title's 24 (comment 5493518990 balances the books).

Noted, not a rider: the #5684 mirror-parity ratchet cannot see a mirror that agrees with a TS twin both renderers ignore. That is a finding for the ratchet's own card.

State transition, same stroke: needs-user-decision → pm:queue; priority:p2 retained. Ledger: objectstack director seat post #12708, summon #8.
