ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling or stored shape is removed, renamed or re-shaped, and no stored row is read, rewritten, converted or dropped, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is the in-process verification boot of @objectstack/verify: a second live boot of one configuration object is refused, and an entry of the app's own `plugins` array that cannot be loaded or registered fails the boot instead of being absent. The other categories are closed on facts: every bumped package publishes (not unpublished); no ADR-0087 id covers these paths and this diff adds none (not registered / already-registered); and the narrowed surface is a runtime boot function, not an interface or a type (not runtime-interface-only / type-surface-only).
