ADR-0087 exemption (no-migration-prescription): a refusal at `objectstack validate`, `compile` and the publish gate of a form open to anonymous intake that declares a file-typed field: no authorable key, spelling or stored shape moves, the parse is unchanged, and no stored row is read, rewritten or converted. A stored view carrying such a form keeps loading until it is next saved, and the repair is the author's choice of where the file is collected (off the public form, onto a signed-in form), 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 The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers this verdict (not already-registered); and the change is a build and door verdict, not a declaration (not runtime-interface-only or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).
