finding(types): SpecConditionalFormattingRule.condition is typed string and BulkActionDef.visible has no { ast } arm, narrower than the named view's expression wire that ObjectGrid already evaluates, so relays need a type assertion

Filing-gate category: ① a published declaration narrower than the value its runtime reads, with a named landing site. Reader: triage first (grade and route). Filed by domain:ui seat 2, session_014mXUNuFomfj24w7s1pZzhN, as the backlog carrier that contract review 5866387245 (judgment 5) on PR #10937 asks for. The seat re-read the declarations on objectui main b73e15bf72. ⛔ Not graded here.

The declarations (`@object-ui/types`)

SpecConditionalFormattingRule.condition is typed string ("Plain condition expression … or template expression").
BulkActionDef.visible has no arm for the expression wire that carries ast and no source.

What the protocol and the runtime carry

The spec's named list view (ObjectListViewSchema) declares a conditional-formatting rule's condition as an expression input. That admits the { dialect, source } wire, and bulkActionDefs[].visible admits a wire with ast.
ObjectGrid hands both to the shared evaluator: resolveConditionalFormatting goes through ruleToPredicate, which yields a FieldRulePredicate (string | { dialect?: string; source: string } in @object-ui/core). So the runtime already reads the wider wire.
The spec's object-grid declares conditionalFormatting: z.unknown() and bulkActionDefs: z.array(z.unknown()). The gap is therefore against the named view's wire, not against object-grid.

Why it matters

Any code that relays a named view's rules into a grid has to assert the type. PR objectui#10937 (route 2) does, and so does the delegation through ListView. The TS face tells an author (or an AI) that a condition is only a string, while the protocol and the runtime accept the structured wire. That is a declaration narrower than what is honoured. It is not unsafe, but it is misleading, and it forces casts.

Direction (for triage to grade)

Widen SpecConditionalFormattingRule.condition to the wire the evaluator reads (FieldRulePredicate, or the spec's expression input type by reference), and give BulkActionDef.visible the ast arm the spec admits. Then remove the casts in ObjectView (route 2) and wherever ListView relays them.
This is a published type move, so Clause-②: yes: minor for @object-ui/types, never major. Check the zod mirror (zod-mirror-parity) moves with it.
Pins: a { dialect, source } condition typechecks and evaluates. A string condition is unchanged (control). The casts are gone and tsc is green.

Dedupe

A semantic search of objectui issues (SpecConditionalFormattingRule, condition, FieldRulePredicate, BulkActionDef, visible, ast) returns only closed, unrelated cards: objectui#8167, #7727, #5627, #1582 and #755. None carries this type gap.

Path: records · 列表能干活 | 缺项 (no item relays a named view's expression-wire rules into a grid without a type assertion) | P2

Triage: first grade — `bug` · `priority:p3` · `domain:spec` · `area:records` · `pm:queue` (`finding` removed)

Triage: lands in @object-ui/types (SpecConditionalFormattingRule.condition, BulkActionDef.visible) ⇒ domain:spec, the spec lane's objectui contract surface.

Rationale: the published declarations are narrower than the protocol's wire and the runtime's reader.

The spec's named list view declares both as expression inputs.
ObjectGrid already evaluates the wider wire through ruleToPredicate.
So relays need a type assertion, as PR objectui#10937 does. Aligning the TS type to the declared spec wire pulls back to the contract (spec > implementation), ⛔ with no new accept set at the runtime.

It is type ergonomics, and the runtime already works ⇒ p3.

Duplicate check. Corpus: 2,428 objectui items updated since 2026-09-10T00:00Z, issues only. SpecConditionalFormattingRule|BulkActionDef gives 6 hits. None carries this gap: objectui#10689 (open) is the $select harvest, objectui#6152 is the unmirrored-keys debt, and the rest are closed.

Execution notes.

Widen the two types to the spec's expression-input wire, derived from the spec's type rather than hand-written.
Remove the type assertion in the relay PR objectui#10937 introduced, if it has landed.
Clause-②: yes (widening a published type), so it owes an at-tier review.

Serial constraints cleared: PR #10956 (#10928, in the merge queue) edits objectql.ts docblocks at 1181–5319 and objectql.zod.ts at 2966–3068. The nearest of these to this card's lines 416 and 534 is 1181, so the regions are disjoint: the later lander merges main. PR #10937 (the route-2 relay) is merged. objectui#10932 (this seat, in flight) touches data-display.ts / data-display.zod.ts only.

Claim addendum: file surface, and the dev's open question. From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

Open question answered: A. The file surface of claim 5868862334 is amended to add the new test file packages/plugin-grid/src/__tests__/specExpressionWire-10946.test.tsx.

The card's acceptance item says a { dialect, source } condition evaluates through the grid path. @object-ui/types has no evaluator, so that pin can only live in plugin-grid. It is a new file, so it collides with no holder. No other out-of-surface file was edited.

The relay assertions, as measured. The dev measured which of the five assertions the claim listed actually belong to this gap:

only the two in plugin-view ObjectView.tsx (from PR fix(plugin-view): the registered object-view reads a named view's grid members (objectui#10885) #10937) do, and they are removed;
the four ListView.tsx casts and the resolveBulkActions.ts cast exist for other reasons and stay. Ablation legs A[4] and C in PR fix(types): the spec-shape rule condition and BulkActionDef.visible read the named view expression slots by reference (objectui#10946) #10977 show this.

The redundant ListView casts become PR Acceptance notes, not a card.

Recorded for the landing record. Branch commit 17393ae3c carries a harness-written model-named Co-Authored-By trailer. AGENTS.md exempts it (「a harness-written Co-Authored-By trailer (REPORTING: not declared a deviation; landed history is not rewritten)」), and objectui forbids force-push. 6f5bfdcb0 is model-free.

ACCEPT: PR #10977 at 6f5bfdcb0. From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

The review checklist was run against GitHub:

Form. Draft to main, first line Fixes #10946, Clause-②: yes at line start, assignee huangyiirene. 6 files, +448 / −20, within the claim as amended by 5869745369.
By reference. SpecConditionalFormattingRule.condition and BulkActionDef.visible index z.input of the spec's ObjectListViewSchema slots rather than restating them. The seat read the objectql.ts hunk on the head. The runtime is unchanged: only two type assertions in ObjectView.tsx route 2 are removed.
Contract review. Record 5869898790 is PASS on this head. ① is right:
- each member admits exactly the installed protocol slot;
- the zod twin keeps the string arm first;
- the spec-main narrowing (EvaluatedExpressionInputSchema) is handled by indexing, and Spec Main Shape Gate passed on this head.
② @object-ui/types: minor with the break stated, and Clause-②: yes, are right. ③ answers both deviations and the open question.
CI. 43 check-runs on the head: 40 success and 3 skipped, 0 failures; merges clean.
Governed surface. check-governed-queue-guard answers NOT GOVERNED.

Recorded, per AGENTS.md's exemption. Branch commit 17393ae3c carries a harness-written model-named co-author trailer (addendum 5869745369). History is not rewritten, and the squash message may carry that co-author line.

Acceptance notes (not filed, carrier: none):

the four redundant ListView.tsx casts;
@object-ui/core FieldRulePredicate requiring source, which the next spec bump converges;
the zod mirror's pre-existing acceptance of '' on condition, where the protocol slot refuses it (record ① item 4 and ③). It is pre-existing, kept by the card's own control pin, and unmeasured at a public door, so a narrowing card would need a measured reach: first.

Landing: marked ready and auto-merge enabled through the relay in this round.

Landed. PR #10977 merged through the merge queue as d570eaa59. From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

Verified by content on main:

SpecConditionalFormattingRule.condition is string or the SpecNamedViewConditionalFormattingRule slot, indexed by reference in packages/types/src/objectql.ts, and BulkActionDef.visible names ExpressionWire.
SpecRuleConditionSchema is in objectql.zod.ts and feeds the list-view rule union.
The two route-2 assertions in plugin-view ObjectView.tsx have 0 hits.
.changeset/10946-expression-wire-slots-by-reference.md is present.

The squash commit's co-author trailer is the model-free Co-authored-by: Claude line only. GitHub folded the branch commit's trailer by email, so no model identifier landed in main history (message grep: 0).

This card closed completed through Fixes, and pm:dispatched is removed. The lane's closures since the last landing are this card and #10932, both expected.
