ADR-0087 exemption (no-migration-prescription): a refusal at `os build`, `os validate`, `os lint` and the page save door of a page component props CEL slot whose source overruns the platform's parse bounds: no authorable key, spelling, export or stored shape moves, and no stored row is read, rewritten or converted. A stored page whose slot is refused keeps loading until it is next saved, and the repair is the author's rewrite of the predicate (shrinking it, or precomputing it into a formula or roll-up field), which no ledger entry can derive. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers this verdict (not already-registered); and the change is a build and door verdict, not a declaration (not runtime-interface-only or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).
