finding(plugin-dashboard): ObjectDataTable honours five undeclared authored column keys as field-meta overrides

[claude]

Found while implementing #6373 (retiring the six FieldMeta keys ObjectDataTable.enrich() wrote into the TableColumn[] slot). Filed unassigned. #6373's fence is the WRITE; this is the same seam's READ, and it is a different adjudication — retiring an inert write costs nothing, while these keys are load-bearing.

Measured (at 9602dc820)

packages/plugin-dashboard/src/ObjectDataTable.tsx, inside enrich(), the overrides handed to buildFieldMeta:

overrides: {
 type: col.type,
 format: col.format,
 options: col.options,
 referenceTo: (col as any).referenceTo,
 currency: (col as any).currency,
 decimals: (col as any).decimals,
},

Five of those six keys — format, options, referenceTo, currency, decimals — are read off the AUTHORED column and are declared by neither TableColumn (packages/types/src/data-display.ts:293) nor its TableColumnSchema mirror. Three are reached through (col as any), which is the same "declared != enforced" tell #5853 removed for type.

This is not a dormant limb. packages/plugin-dashboard/src/__tests__/ObjectDataTable.cells.test.tsx exercises it directly:

const schema: any = {
 type: 'object-data-table',
 objectName: 'opportunity',
 columns: [
 { header: 'Amount', accessorKey: 'amount', format: '$0,0' },
 { header: 'Probability', accessorKey: 'probability', format: '0%' },
 ],
};

and asserts $150,000 / 60% render. Note the : any on the schema — that annotation is what lets the undeclared key past tsc in the test itself.

Why it matters

The widget honours an authoring vocabulary the published types refuse. A TypeScript author who writes the tested spelling gets a compile error; TableColumnSchema.parse strips the key without a word; and a JSON author gets working behaviour that no declaration promises and no validator protects — so a typo (decimal for decimals, precision for scale) is silently inert rather than a loud parse failure. That lenient face is precisely where AI-authored metadata errors hide and spread.

Suggested disposition

Declare-or-retire per ADR-0049, adjudicated per key rather than as a batch, using the rule stated in #6373's PR body — with the direction reversed, because unlike the six retired writes these five have a real consumer:

• Declare the ones with a genuine authoring story (format is tested and documented behaviour) on TableColumn + the zod mirror, dropping the as any.
• Retire any that only ever mattered as a schema-derived value, in which case the object schema is the single source and the column-level override goes.

Sizing note: this touches the published @object-ui/types surface and needs the zod-mirror-parity pairing plus a changeset, so it is not a one-line annotation.

• finding(plugin-dashboard): ObjectDataTable's enrich() spreads a FieldMeta into the TableColumn[] slot, writing seven keys TableColumn does not declare #6373 — the write half of the same seam (the sibling adjudication)
• finding(plugin-grid): ObjectGrid's generateColumns() is untyped (any[]), so nothing type-checks what it writes into DataTableSchema.columns: TableColumn[] — the hole that hid #5853 and #5453 #6004 — the same untyped-boundary class at ObjectGrid.generateColumns()
• finding(types): TableColumn.type disagrees three ways — interface declares 8 literals, zod mirror accepts any string, renderer's live read set handles values outside the union via an as any cast #5853 — type, the one member of this override set already adjudicated
• finding(types): DashboardWidgetSchema SILENTLY DROPS every undeclared widget key — the file's own docstring names this failure mode, and it still applies to the keys nothing declares #6002 — DashboardWidgetSchema silently dropping undeclared keys, the same silence one layer up

Triage: domain:ui (per-key declare-or-retire on the five undeclared field-meta override keys ObjectDataTable.enrich() reads; touches published @object-ui/types TableColumn + zod mirror + changeset — the card's own sizing note), type Bug (a tested, load-bearing authoring vocabulary the published types refuse and the schema parse silently strips). State:

Blocked-by: #6004

Rationale: same shared TableColumn declaration surface as #6004 (in flight) and sister card #6424 — three cards would collide on packages/types/src/data-display.ts; chain them (#6004 → #6424 → #6425 or a ui-seat fold of the latter two under the five gates: same defect shape, same declaration surface, both already adjudication-charted per #6373's stated rule). Unlock note: on #6004 close, re-take both read censuses on the merged ref before dispatch.

Unblocked — Blocked-by: #6004 resolves. ⚠️ Re-measure before dispatch: the merge that closed it changed this card's terrain.

#6004 closed completed on 2026-08-26T02:16:37Z via merged PR #6461, "type ObjectGrid's column emit against the TableColumn[] slot it fills".

Re-read from main as part of the unlock, because the merge that closes an upstream is the one most likely to have moved the ground under its dependants:

• packages/plugin-grid/src/ObjectGrid.tsx — generateColumns is now useCallback((): ObjectGridColumnDraft[] => {, and the call site's (col: any) re-widening is gone. The any hole is closed.
• packages/types/src/data-display.ts — TableColumn is unchanged: no headerIcon, options, pinned, wrap, essential, or size among its declared keys.

#6461 typed the boundary via a plugin-grid-local ObjectGridColumnDraft rather than by declaring the extra keys on TableColumn. This card is about plugin-dashboard's ObjectDataTable, which is a different producer on the same consumer — so the closure does not touch it directly, but it does change what "undeclared" means and what the fix would converge on. That makes the premise re-measurable rather than settled.

Returned to pm:queue, not dispatched this round. Measure first: for each of the five keys this card names, where it is declared now and whether the consumer still reads it. ⛔ Do not implement from this card's body as written; it describes a pre-#6461 tree.

Sibling cards unblocked by the same closure, same warning: #6424, #6457, #6458, #6459.
