ADR-0087 exemption (no-migration-prescription): a write-door verdict that now answers on one more kernel topology: the per-item _lock gate (save, publish, rollback, delete) used to return no refusal on a kernel with no environmentId, and now refuses there what it already refused on an environment-bound kernel. No authorable key, spelling, export or stored shape is retired or renamed: MetadataLock keeps its four states, every stored row keeps parsing and is neither read nor rewritten by an upgrade, and which items an operator meant to keep editable 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 The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers a lock verdict (not already-registered); and the change is a door verdict plus a count, not a TypeScript declaration (not runtime-interface-only or type-surface-only).
