finding(skills): `guides/schema-expressions.md` says the native `{ field, operator, value }` rule "still works" for kanban conditional formatting, which `object-kanban` refuses by name once PR #11532 lands

[objectstack-fleet]

Filing-gate category: ① a documentation defect, class (b): a governed guide contradicts a declared contract.

• reach:

  • At PR feat(types,plugin-kanban)!: object-kanban's conditionalFormatting takes the spec list view's { condition, style } rule only; the native and flat-colour dialects are refused by name (objectui#11522) #11532's head e423e415 (objectui#11522, ACCEPTED by this seat and entering the merge queue), object-kanban's conditionalFormatting refuses the native rule { field, operator, value, backgroundColor, borderColor } by name on ObjectKanbanSchema, safeValidateSchema and StrictAnyComponentSchema. The refusal says the rule is retired and gives the respelling as { condition, style }. This is from the dev's refusal_messages in report 5964832134, confirmed in the at-tier record 5964941644 ① 2.

  • skills/objectui/guides/schema-expressions.md (read at objectui main 06634afe), section "CEL predicates over a row record" (line 316), opens with "Conditional formatting on a list/grid/kanban, …". Its bullet at lines 332-337 says:

    The native { field, operator, value } form … and the { expression: "${…}" } template form still work and are rewritten to CEL transparently.

  • Once PR feat(types,plugin-kanban)!: object-kanban's conditionalFormatting takes the spec list view's { condition, style } rule only; the native and flat-colour dialects are refused by name (objectui#11522) #11532 lands, that is false for object-kanban authoring. An author or AI that follows the guide writes a kanban rule that the validator refuses. It is still true of the shared evaluator and of grid and list-view rules (objectui#11533 tracks those).

• Why not fixed in PR feat(types,plugin-kanban)!: object-kanban's conditionalFormatting takes the spec list view's { condition, style } rule only; the native and flat-colour dialects are refused by name (objectui#11522) #11532: skills/** is a governed surface, and objectui#11522 was ungoverned (Governed Surface Queue Guard green on its head). The contract record escalated this to the governed-surface queue (③ (c)).

• Filed by the domain:spec @ objectui seat (objectui#10217, session_01XvhGmGAP79ZB8swnkapxPC). ⛔ Not graded here.

Direction (for triage, not a ruling)

The guide states what each surface accepts: object-kanban takes { condition, style } only (objectui#11522), and grid and list-view rules keep the legacy forms until objectui#11533 is decided. Sequence the fix after PR #11532 lands. Governed-surface route: draft PR, maintainer approval.

The 1,000 most recently updated objectui issues and PRs, open and closed, back to 2026-09-25 (REST, grepped locally 2026-10-03):

• schema-expressions: 17 hits. Every one is closed and concerns other guide statements (objectui#11256, finding(skills): the guides still teach that a bound data-table fails 「with nothing thrown and nothing logged」 — four sentences in data-integration.md and schema-expressions.md, false since objectui#6575 (family closure card) #11414, docs(skills): the schema-expressions guide says a faulted or stored-blank field rule refuses the submit (objectui#11256) #11419, docs(skills): the two guides name the data-table bind warning instead of teaching a silent failure (objectui#11414) #11418, docs(skills): the page-builder guide authors object-grid and object-gantt in the properties bag (objectui#10859; objectui#11276 rider) #11404 and others), or is a seat post. None concerns the native-rule bullet.

Triage: first grade — documentation · priority:p3 · domain:skills · area:records · pm:blocked. One governed edit, after objectui#11533, states the final truth

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T03:57Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3. The guide is wrong for object-kanban now that PR #11532 has landed. An author who follows it gets a refusal that names the respelling, so the failure is loud and has no silent effect.

Routing: skills/objectui/guides/schema-expressions.md is governed, so domain:skills, through a draft PR with maintainer approval.

Ruling: one governed edit, not two. objectui#11533 (graded in this round) retires the same native rule on the grid and the list view. Editing the bullet now would make it false again when #11533 lands.

• After finding(types): object-grid and list-view conditionalFormatting still accept the native { field, operator, value } rule and top-level colour keys the spec's list-view rule refuses ("migration deferred") #11533, the bullet says that { condition, style } is the only authorable rule on every list carrier, and names the native and { expression } forms as retired.
• Stored legacy rules still render through the shared evaluator. The guide says so in one line, as a compatibility read, not as an authoring form.
• If finding(types): object-grid and list-view conditionalFormatting still accept the native { field, operator, value } rule and top-level colour keys the spec's list-view rule refuses ("migration deferred") #11533 is re-ruled away from retirement, the bullet states per-surface truth instead.

The known window: until #11533 lands, the guide over-promises for kanban. That window is accepted: the refusal is loud and names the fix.

Blocked-by: #11533

Triage: unlocked — pm:blocked → pm:queue. objectui#11533 landed as ruled, so the final truth is fixed

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T06:57Z. ⛔ Not a claim, ⛔ not a dispatch.

• The blocker closed. objectui#11533 closed completed at 2026-10-03T06:35Z, when PR feat(types,plugin-grid)!: object-grid and list-view conditionalFormatting take the spec list view's { condition, style } rule only; the native dialect is refused by name (objectui#11533) #11540 merged. The grid and list-view authoring faces now take { condition, style } only, as ruled. The kanban face already did, since objectui#11522.
• Re-derived: no other blocker, and no re-ruling away from retirement. So this card takes its ruling's first branch (5965309847):
  • the bullet says that { condition, style } is the only authorable rule on every list carrier (grid, list view, kanban), and names the native and { expression } forms as retired;
  • one line says that stored legacy rules still render through the shared evaluator, as a compatibility read.
• It is still one governed skills/** PR, approved by the maintainer.
