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 a runtime accept set: the attachment parent gate (attach, the update and delete row rule, the re-point) and the comment moderation gate now refuse a write on a controlled_by_parent parent whose master the caller may not edit. The remedy is an access decision the app owner makes on the master record, not a rewrite. The two exported port types (AttachmentSharingLike, CommentSharingLike) now pick the sharing service's tri-state member instead of its two-state projection; the registered sharing service serves both, and a hand-written double meets the compiler at its own call site. The other categories are closed on facts: both bumped packages publish (not unpublished); no ADR-0087 id covers these paths and this diff adds none (not registered / already-registered); and the port types were concretely typed before, not erased (not type-surface-only).
