ADR-0087 exemption (no-migration-prescription): No metadata moves: no authorable spelling, export or stored shape is removed, renamed or re-shaped, and no stored row is rewritten, converted or deleted, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is one CLI invocation: an `os migrate apply --allow-destructive` run that would drop `organization_id` from a table outside the platform inventory is refused until the organization-ownership ceremony's marker is verified; the remedy is running that ceremony, never a rewrite of a package source or a stored row. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no exported declaration is removed or narrowed (not runtime-interface-only, type-surface-only or runtime-export-retired).
