ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling, export, type or stored shape is added, removed, renamed or re-shaped, and no stored row is read, rewritten or converted, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is a runtime admission: the security middleware refuses an engine operation whose context names no user, no position and no permission set and is not a system context, which it used to hand through. The other categories are closed on facts: both packages publish (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no TypeScript declaration moves (not runtime-interface-only or type-surface-only).
