ADR-0087 exemption (no-migration-prescription): No `@objectstack/spec` key, accepted value, stored row or stored shape moves. The spec's `ComponentPropsMap['object-calendar']` and `['object-gantt']` rows already refuse every flat key this change stops reading, `@object-ui/types` stopped declaring them in the earlier slice of #25923, and both producers in the console (`ListView` and `ObjectView`) already write the block, so no metadata the spec accepts reaches the retired read. A stored-row census over every metadata source this repository reaches (examples, apps, the console's shipped metadata, seeds, fixtures, platform-objects) found no stored view or node that writes the binding flat, so `objectstack migrate meta` has nothing to rewrite. What narrows is the drawing outcome for a host that mounts `ObjectCalendar` or `ObjectGantt` directly with a flat node: it now reaches the refusal screen. The `@objectstack/spec` half is prose only: the two refusals no longer say the renderer still reads the flat spelling. The other categories are closed on facts: the packages publish (not unpublished); no ADR-0087 id covers this change (not registered or already-registered); the narrowed type members are package-local hand-off types that neither package's entry exports (not type-surface-only or runtime-export-retired).
