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, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is runtime resolution and two write doors: a stored grant that names no permission set, or names one only another organization holds, stops conferring through the resolver; a write naming a grant after another organization's set is refused; and the break-glass guard judges one more column. The remedy is data (a grant re-pointed at a set of its own organization), never a rewrite of anyone's code or metadata, and the one-time backfill that names existing grants already ships. The other categories are closed on facts: every package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no TypeScript declaration moves (not runtime-interface-only or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).
