Kanban board draws only the declared lanes, in their order: ObjectKanban reads kanban.lanes

domain:spec#2 · os-tesla · session_01L9qibx5r5nhDMwpRs4SL6D

Filing gate: ③ the renderer half of #28018, whose contract half lands in PR #28196 (claim 6526161926 and amendment 6526184775 name this follow-up; contract review 6528382115 PASS). ⛔ Not a claim. Triage sets the lane and grade.
Reach: any kanban whose view filters out a status. HotCRM's task board filters out completed tasks but still draws an always-empty Completed lane, and its author cannot reorder lanes, until the console reads the key.

Observed (once PR #28196 is on `main`)

KanbanConfigSchema.lanes (packages/spec/src/ui/view.zod.ts) is declared: an ordered list of the group field's stored option values. Lint refuses a non-option lane (list-view-kanban-lane-unknown) and a repeat (list-view-kanban-lane-repeated) at validate, build and the publish door.
ui/packages/plugin-kanban/src/ObjectKanban.tsx effectiveColumns (≈L1453–1482) still builds one lane per explicit column or per option and reads no lane list, so the key draws nothing. The liveness/view.json kanban row names lanes at planned strength.

Wanted

effectiveColumns filters and orders its lane list by kanban.lanes when set. A record whose value is not listed lands in the existing Uncategorized lane (≈L1819–1873), never hidden. Test plus ablation.
The liveness note moves lanes from planned to live in the same PR, with the reader as evidence.
Riders named by the contract review 6528382115 (should-fix, non-blocking): S1 an author of lanes gets no "declared, not yet drawn" word today, because the blanket kanban row cannot carry authorWarn. Flipping the row to live here closes it. S2 a one-line note in the checkKanbanLanes module docblock that any future widening of inline options must join its option map.

Dedupe words: kanban lanes renderer, effectiveColumns lanes, hide empty kanban lane, kanban lane order.

⛔ Not a claim.

Read fresh. This is the renderer half of kanban.lanes. PR feat(spec,lint): a kanban board chooses which lanes it draws, and in what order (kanban.lanes) #28196 merged at 2026-10-30T17:21Z, so the card is not blocked. The parent Kanban config cannot hide an always-empty lane or choose its lanes #28018 is p3, so this card is p3 too.
One-PR cross-domain exception: only the packages/spec/liveness/view.json kanban row, for lanes from planned to live. Riders S1 and S2 ride only if they stay inside that file.

Claim amendment · 2026-10-31T02:45Z · amends claim 6537960788 after the card thread's read-only pre-check on origin/main 6285203d. Append-only.

File surface (replaces the claim's): the kanban branches of ui/packages/plugin-list/src/ListView.tsx and ui/packages/plugin-view/src/ObjectView.tsx; one shared helper in @object-ui/core; tests in those packages, plus a pin in ui/packages/plugin-kanban; the packages/spec/liveness/view.json kanban row only; a root changeset. Stop and explain on any breach.

Why: ObjectKanban never receives kanban.lanes. Both object-kanban producers forward only named block keys, and ComponentPropsMap['object-kanban'] has no lanes. Adding one would be a spec edit, which the triage exception doesn't cover. So the producers map kanban.lanes onto the existing node key columns ({ id, title } in the author's order, the title taken from the option label, a lost-kind lane collapsed: true per #26612). An unlisted value still lands in Uncategorized, both when the client buckets values and when the lanes page, so nothing is hidden.

Clause-②: no (the seat's expectation; a new @object-ui/core export would move it to yes (widening), and the dev measures it on the diff)

Riders: S2 doesn't ride (checkKanbanLanes is in packages/lint, outside the liveness file). The TSDoc on KanbanConfigSchema.lanes ("Lands ahead of its reader…") goes stale once this lands. That is a spec-source edit outside this card, and the seat files it, together with S2, as a domain:spec follow-up after this PR merges.

Claim amendment 2 · 2026-10-31T03:32Z · amends claim 6537960788 (and amendment 6537973671) after the card thread's os-dev-report 6538446315. Append-only.

Clause-②: yes (widening: @object-ui/core gains the public export kanbanDeclaredLanes and its two types; the liveness kanban row's lanes moves from planned to live; no accept set moves)

The seat expected this in amendment 1, and the dev's measure on PR #28291 confirms it, so the PR goes to the contract-review lane before the seat lands it.

Seat read on head 8f4d9c61, no blockers so far:

The file surface matches amendment 1, and ObjectKanban.tsx is unchanged.
Both producers call the one helper and spread columns only when the view declares lanes, so a view without lanes builds the same node as before.
ObjectView's memo now depends on objectSchema, which it reads for the option labels.
One ListView.tsx hunk sits outside case 'kanban': the @object-ui/core import line. Seat 4's lint/types: 14,366 no-explicit-any warnings can never red CI — make it an error on packages/types/src, delete the vestigial (schema as any) reads, and type ComponentRendererProps with unknown #25918 has not landed.

PR	merged 2026-10-31T04:26:06Z as `85a1b9d8` through the merge queue, on the first pass
`origin/main` content	`ui/packages/core/src/utils/kanban-declared-lanes.ts` is present. Both `object-kanban` producers (`ListView.tsx`, `ObjectView.tsx`) hand declared lanes to the board as `columns`. The liveness `view.json` `kanban` row reads `lanes` as live.

State: Fixes #28211 closes the card as completed. pm:dispatched comes off in the same stroke as this note. The review's boundary flag (the stale KanbanConfigSchema.lanes TSDoc, plus rider S2's checkKanbanLanes docblock line) is filed as domain:spec follow-up #28319, as committed. Nothing else remains on this card.
