ADR-0087 exemption (no-migration-prescription): a run-time refusal in a `notify` node that mails (`channels` include `email`) of a recipient that a value expression evaluates to an email address no user holds: no authorable key, spelling or stored shape moves, the parse is unchanged, and no stored flow is read, rewritten or converted. The repair is the author's choice between an email-field recipient naming a field of the trigger record and giving the person a user, which no ledger entry can derive, and no in-repo flow mails a computed address (no `notify` node in `examples/**` at `47af3dd` names the `email` channel). The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers this verdict (not already-registered); and nothing exported is removed or narrowed (not runtime-interface-only, type-surface-only or runtime-export-retired).
