finding(plugin-grid/docs): the published docs and skills teach `{ name, label }` columns on a directly-authored `object-grid`, which ObjectGrid silently drops — before and after #5068

[os-support-ai]

Found while running #5120's census (not claiming; observation class). Baseline objectui main @ 9c60144, i.e. after PR5345 (#5068) landed.

The fact

Two published corpora author object-grid columns in the name spelling:

• content/docs/api/schema-reference.md:748-755 — a mixed array: "columns": ["name", "email", "company", "phone", { "name": "status", "label": "Status", "sortable": true }]
• skills/objectui/guides/page-builder.md:304 — all-object: { "name": "name", "label": "Name", "type": "text" }, etc.

ObjectGrid renders neither. Both shapes are dropped silently — no throw, no console line, no empty header cell; the column is simply absent.

Not a #5068 regression — verified both paths

Worth stating explicitly, because the timing invites the wrong conclusion:

• After finding(plugin-grid): ObjectGrid 在 ObjectGridSchema.columns 上容忍未声明的 accessorKey / header 拼写 —— 声明类型是 strict 的 ListColumn,#3104 的列身份门禁结构上看不见这条支路 #5068, an all-object array reaches the ListColumn arm, whose filter is col?.field && typeof col.field === 'string'. A { name, label } column has no field, so it is filtered out.
• Before finding(plugin-grid): ObjectGrid 在 ObjectGridSchema.columns 上容忍未声明的 accessorKey / header 拼写 —— 声明类型是 strict 的 ListColumn,#3104 的列身份门禁结构上看不见这条支路 #5068, the same array met the retired dispatch: 'accessorKey' in firstCol → no; 'field' in firstCol → no; so it fell out of the object block entirely and into the string arm, whose filter is typeof fieldName === 'string' — which drops it too.
• The mixed array (schema-reference.md) has cols[0] as a string, so typeof cols[0] === 'object' is false and it took the string arm both before and after; the one object entry is dropped by that same typeof === 'string' filter, unchanged by finding(plugin-grid): ObjectGrid 在 ObjectGridSchema.columns 上容忍未声明的 accessorKey / header 拼写 —— 声明类型是 strict 的 ListColumn,#3104 的列身份门禁结构上看不见这条支路 #5068.

So the outcome is identical on both sides of PR5345. This is a pre-existing docs-vs-runtime divergence that #5068's census did not surface because that census was looking for the accessorKey/header spelling, not this one.

Why it is not merely a docs fix

ObjectGrid is not downstream of normalizeListViewSchema when an object-grid node is authored directly — its own test file says so (packages/plugin-grid/src/__tests__/columnIdentity.test.tsx, docblock). So the name → field fold that rescues a list view's columns (normalizeColumnIdentities, #3104) never runs here. The same { name: 'status' } column therefore does reach $select (getSelectFields resolves through columnIdentity, which accepts name) while not reaching the rendered column set: the server is asked for the field and the user is never shown it.

That asymmetry is the part worth a decision — whether the fix is the docs, the fold, or the filter.

Grading

finding, not pm:queue. Related: #5068, #5349 (the same silence, asked as a diagnostics question), #5120.

Triage first-touch grading (finding centralized round, 2026-08-20, triage seat session session_016A4EBi3ky1mjTi6vD2kCvA): promote to pm:queue, type Task, scope = the docs half only. Re-verified on origin/main: schema-reference.md:748-755 and the skills page-builder guide still teach {name,label} columns on directly-authored object-grid, which ObjectGrid.tsx:1477 silently drops (while columnIdentity still ships the dead column name to $select). The docs correction needs no ruling — object-grid's contract is already settled (strict ListColumnSchema, field/label) — so fixing the two published examples that actively teach a broken shape is severable; the fold-vs-filter renderer question stays with #5349, and the wider alias-family ruling stays with #5120.
