Preconditions
- A byte-bound accepted public state exists or the record explicitly says none exists.
- The replacement path, authority, and rollback rule are declared before fault injection.
- No network call, production credential, citizen record, passport body, or private receipt is used.
Portability and replacement
Artifact: Portable evidence packages and reproducible tests.
Replacement: Alternative assurance providers and internal verification.
Rollback rule
Rejected, incomplete, stale, disputed, or corrupted migrations cannot overwrite accepted state. Restore the last verified local projection and publish the degraded state.
Unresolved residuals
- Contractor unavailable, compromised, conflicted, or wrong.
- A local deterministic drill does not prove supplier cooperation, production capacity, legal authority, or real recovery time.
Truth boundary
Synthetic local exit-readiness fixture. It does not prove a live alternative, actual portability, supplier cooperation, production recovery, service continuity, or legal authority.
Authority and record status
Responsible authority: State Registry and continuity governance.
Deterministic local drill; no production action occurred.
Revision date: . Public corrections may be initiated through the diplomatic contact route.
