Record programme, fingerprint, algorithm, public-key reference, custody, validity, and accountable registrars.
Signing trust and staging authority
P003 accepts public-key evidence, never upstream private keys. A valid signature authenticates a package; it does not approve editorial content or authorise promotion.
Record programme, fingerprint, algorithm, public-key reference, custody, validity, and accountable registrars.
Require independent approval and evidence before the key can authenticate a package.
Check programme binding, validity, revocation, monotonic sequence, package hash, and signature.
Overlap public verification safely while preventing the retired key from signing new sequences.
Block immediately, quarantine affected packages, assess exposure, and preserve the audit trail.
End trust automatically; renewal requires a new governed ceremony.
Replay protection
P003 records only the last accepted sequence after a verified promotion. Repeated or lower sequences are quarantined, preventing an older validly signed package from replacing newer public truth.
