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, in two places: the import's reference resolution stops matching cells against a lookup's target object whose existing `enable` declaration already refuses that read on every data route (the remedy is the declaration the author already wrote), and a field of the legacy, schema-refused type spelling `'reference'` no longer takes a target from its raw `reference` key, since the spec's arbiter gives it none (no shipped producer declares one). The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no exported declaration is removed or narrowed — `ImportProtocolLike` gains one optional member (not runtime-interface-only or type-surface-only).
