ADR-0087 exemption (no-migration-prescription): a refusal at `objectstack validate`, `compile` and the publish gate of an action copy sentence (`confirmText`, `successMessage`, a page row's `errorMessage`) that is blank, names an unbound root, carries a single-brace or raw-shown `${…}` token, or holds logic in a hole: no authorable key, spelling or stored shape moves, the parse is unchanged, and no stored row is read, rewritten or converted. A stored row whose sentence is refused keeps loading until it is next saved, and the repair is the author's rewrite of the sentence (which root a hole should name is the author's intent), which no ledger entry can derive. The other categories are closed on facts: the packages publish (not unpublished); no ADR-0087 id covers this verdict (not already-registered); and the change is a build and door verdict, not a declaration (not runtime-interface-only or type-surface-only).
