+`@objectstack/spec@17.2.0`, each refusal is paired with a control that accepts
+the same payload minus the key. Same correction as objectui#7014 / PR #7510 made
+to the published JSDoc; the package bumps and the declared behaviour are
+unchanged.

 A static option may also carry a `description` — secondary text the picker's

+field** with a 422 — the key lives on the runtime read model the widget consumes
+and must never reach authored object metadata

 `dataSource` a host injects and the `onCreateNew` callback it passes are widget props,
 not metadata.
