fix(plugin-view): forward the canonical table.columns on the non-grid paths

[os-support-ai]

Fixes#5269

ObjectViewSchema.table is Partial< Omit< ObjectGridSchema, 'type' | 'objectName' > >, where columns is the canonical spelling and fields carries @deprecated Use columns instead. ObjectView does not spread table; it forwards a hand-written whitelist, and that whitelist had exactly one read of table.columns in the file — the grid one. The other two field-list read points took the deprecated key alone, so table: { columns: [...] } — the shape the type recommends — produced an empty field list off the grid path from a schema that compiled and read correctly. Same silent-success shape as #5102, different mechanism: not a whitelist that knows only legacy spellings, but one that disagreed with itself between two rendering paths.

Both sites now read the canonical key first and keep the deprecated one as a working alias, the shape #5102 settled for its four pairs. Precedence is unchanged: a named view's columns, then the active view's, then the table segment. schema.table?.columns also joins the generateViewSchema dependency list alongside the new read.

Re-derived against current origin/main (3fbbea1f3), because the card is stale

The region was reworked twice today (#5102, then #5270 / PR #5294). Card vs. tree, measured:

the card says	on 3fbbea1f3
:842baseProps	still :842, and still table?.fields only — confirmed
:1056 / :1057 grid	moved to :1085 / :1086, unchanged in substance
:1247 delegated	moved to :1284, still table?.fields only — confirmed
three read points	four — the useCallback dependency list at :1021 reads schema.table?.fields too, and a memo that reads a key without depending on it keeps serving a field list the author has already replaced

The defect stands. Its reach does not, in either direction — the affected surfaces were measured rather than taken from the card:

• kanban — real. baseProps.fields becomes cardFields, which ObjectKanban reads.
• tree — real, and not named on the card. ObjectTree reads schema.fields, fed from the same baseProps.
• delegated renderListView — real. ListView reads schema.columns as its whole column set.
• gallery / calendar — named on the card, but not reachable this way, and the same holds for timeline / gantt / map. None of those five reads a field list off its schema at all: every .fields in them is objectDef.fields (object metadata) or gallery's schema.grouping.fields. The forwarded value is inert there, before this change and after it. No ceremonial tests were added for them; the measurement is recorded in the test file header instead. (Each zero was counter-probed with .titleField in the same file — the first counter-probe caught a regex of mine that read zero on ObjectCalendar for the wrong reason.)

One shape question the fix raised, answered at the boundary

table.columns is string[] | ListColumn[], and the two slots disagree about which half they can hold:

• the delegated list-viewcolumns slot declares the same union and ListView reads both, so it takes the value raw — flattening there would throw away the label / width the author wrote;
• the non-grid baseProps slot is a names slot: both segments ahead of table declare string[], and ObjectKanban indexes the record by each entry (resolveKanbanCardFields casts straight to string[]).

Raw forwarding into the second one would have handed kanban a non-empty card field list naming nothing — which renders emptier than the bug being fixed, because a non-empty list suppresses ObjectKanban's highlightFields fallback. That is #5270's failure again (a value in a slot whose declared shape it lacks), so it is answered the same way: columnIdentity from @object-ui/core, the repo's converged identity reader (#3104) and the very fold ObjectGrid applies to this same value when deriving $select. One authored table.columns now resolves identically on both paths. It returns undefined, never [], when nothing resolves — a truthy empty array would stop the || chain short of table.fields.

No new spelling becomes acceptable: the accepted set is what columnIdentity already accepts everywhere else in the repo, and the canonical key being honoured here was already declared.

Verification

Run from the repository root (plugin-view owns a standalone vitest.config.ts, so the invocation guard does not cover a package-cwd run here).

• pnpm exec vitest run packages/plugin-view — 16 files, 172 tests, all green at 942197219, including the objectViewHostSurface fence pin (my edits add no (schema as any) read, so the derived key set is unchanged), canonicalTableKeys (ObjectViewSchema 的 table / form 子配置类型零声明成员(Omit 被索引签名塌掉),且 ObjectView 的转发白名单钉在 ObjectGridSchema 的 legacy 键上 —— 规范键 pagination/selection/filter/sort 全部不读 #5102) and namedViewSortArity (A named view's sort array is forwarded into gridSchema.defaultSort, declared a SINGLE { field, order } — ObjectGrid re-wraps it and parseSchemaSort drops it, so the grid shows no sort at all #5270).
• pnpm --filter @object-ui/plugin-view type-check — green (tsc --noEmit && tsc -p tsconfig.test.json; the script is spelled type-check in this repo, and the run echoes it, so this is not a zero-match pass).
• pnpm --filter @object-ui/plugin-view lint — 0 errors.
• check:control-bytes, check:phantom-deps, check:self-import, check:esm-specifiers, scripts/check-changeset-no-major.mjs — all green at 942197219.

No build artifact sits between the edit and the thing under test: the suite imports the subject as ../ObjectView (source), and the root Vitest config aliases every @object-ui/* specifier — @object-ui/core, where columnIdentity comes from — to packages/*/src. The dist/ built for type-check is not on the test's resolution path.

Reverse-verification (fix reverted with the tests kept, prediction written before the run): predicted 7 red and 7 green-on-both-legs; observed exactly that, with the predicted values.

Red, all seven pinning the defect: kanban forwards table.columns as the kanban card fields ([]), kanban prefers the canonical … over the deprecated (['owner']), kanban resolves the ListColumn[] form … to field NAMES ([]), tree forwards table.columns as the tree view fields (undefined), delegated hands over a canonical table.columns (undefined), delegated hands over the ListColumn[] form … unchanged (undefined), delegated prefers the canonical … over the deprecated (['owner']).

Green on both legs, so stated rather than counted — they pin the halves that must not change, not the defect: the three still forwards the deprecated table.fields aliases (kanban / tree / delegated), the two keeps a named view outranking the table segment precedence tests, the grid-path control, and falls through to table.fields when no column entry names a field (green before for a different reason — the canonical key was ignored entirely).
