ADR-0087 exemption (no-migration-prescription): a build-time verdict about handler code: the rebind makes a handler that failed in the sandbox run as written, and every refusal is of handler code the sandbox cannot run as written or of a parameter list the rebind cannot re-emit faithfully. No authorable key, spelling, export or stored shape moves, and no stored row is read, rewritten or converted. A refused handler keeps running bundled, so no consumer has to edit anything for its build to succeed, and the edit that makes it a body again is a change to handler code, which no ledger entry can derive. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id covers the lowering (not already-registered); and the change is a build verdict, not a declaration (not runtime-interface-only or type-surface-only).
