+> **`quickAdd` and `allowCollapse` were rows of the table above and are not authorable on this board.** `allowCollapse` is **refused by name** by the strict authoring face, which does not declare it at all — a document carrying it fails validation rather than merely going unread, and `@object-ui/plugin-kanban` has no read site for it. `quickAdd` still parses, because the strict face does declare it, but an object-bound board never honours it: the Quick Add control is gated on an `onQuickAdd` runtime slot and no `object-kanban` path supplies one, so `@object-ui/sdui-parser` answers an authored `quickAdd: true` with an `inert-quick-add` warning. objectui#8285 ruled that key retired (director seat, decision batch 91). ⚠️ `@object-ui/types` still declares **both** on its mirror of this face, so a reader will find them there; that half is objectui#8801, not this table.

 > `columns` is declared on this face since objectui#8913, as the pair of array shapes `@objectstack/spec` declares — an array of `{ id, title }` lanes, **or** an array of bare value strings. A **mixed** array is refused: the renderer decides which shape it has from the first element alone, so a mix yields a blank lane and mis-bucketed cards. A lane accepts `id`, `title`, `cards`, `limit`, `className` and `collapsed`, which are the members the board implementations read; `id` is a **string** — the authored face keeps that narrowing, and since objectui#8993 a non-string lane id no longer renders every card twice: the bucketer's leftover sweep keys membership the way the injection already did (a lane `1` takes the group `'1'`). When a lane carries `cards`, each card is judged — a card with no `title` is refused. An undeclared lane key is accepted and dropped, not refused, which is this tolerant face's posture; the strict authoring face refuses it by name.
 >
 > ⚠️ The **bare-string array applies only to a board with no `groupBy`.** It is declared so this package does not refuse an authoring the protocol allows. The renderer reads a bare-string lane list only when a board has no `groupBy` — so on a board that *does* declare one the strings are ignored and the lanes come from the group field's picklist options or from the data. Since objectui#8990 made `groupBy` optional, a lane-less board is a valid authoring and this arm is live on it: the lanes are drawn, titled by the **raw strings** (a grouped board titles its lanes with the picklist *labels* instead). ⚠️ Such a board holds **no cards** — with no lane key the records are never distributed — and dragging a card writes nothing back. It is lane headings, not a populated board; to control the lanes of a working board, declare `groupBy` and write the `{ id, title }` array.
