ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling, export or stored shape is removed, renamed or re-shaped, and no stored row is read, rewritten, converted or dropped, so there is nothing for `objectstack migrate meta` to rewrite. What narrows is a runtime accept set on one settings key, `auth.mfa_required`, judged against the deployment's `OS_AUTH_TWO_FACTOR` env var at save time; the remedy is a deployment change (set the env var on, or remove it), which no ledger entry can derive. The other categories are closed on facts: the bumped package publishes (not unpublished); no ADR-0087 id covers this key and this diff adds none (not registered, not already-registered); no published export is added, removed or retyped, so no interface or type narrows (not runtime-export-retired, runtime-interface-only or type-surface-only).
