ADR-0087 exemption (no-migration-prescription): the write doors refuse, by the strictest lock among the stored rows in scope, writes they used to admit when the store returned a looser row first. No authorable key, spelling, export or stored shape moves: every stored row keeps parsing, nothing is read or rewritten at rest, and which row an administrator meant to lock is not something a ledger entry can rewrite. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers the lock gate (not already-registered); and the change is a door verdict, not a declaration (not runtime-interface-only or type-surface-only).
