ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling, export or stored shape is removed, renamed or re-shaped, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is one runtime read position: the generic data door stops evaluating a filter condition on a lookup's target object whose existing `enable` declaration already refuses a query of it on every data route, and the remedy is a filter the caller can already write. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no exported declaration is removed or narrowed (not runtime-interface-only or type-surface-only).
