ADR-0087 exemption (no-migration-prescription): a refusal of a written VALUE at the record validator's time arm: no authorable key, spelling or stored shape of metadata moves, and no schema, type or export changes. `packages/spec` gains one sentence in the built-in validation-message catalog (`invalid_time_zoned`, a rendering variant of the existing `invalid_time` wire code, which is unchanged). A stored row keeps whatever it holds, and which wall clock a zone-suffixed time of day meant is not something a ledger entry can decide. The other categories are closed on facts: the packages publish (not `unpublished`); no ADR-0087 id covers a write-door value check (not `registered` / `already-registered`); and the change is runtime behaviour, not a TypeScript declaration (not `runtime-interface-only` / `type-surface-only`).
