Attestation Anatomy
RFC-001: The .sent Cryptographic Evidence Container
High-consequence systems cannot clear fiduciary or regulatory liability on narrative
logs alone. Non-repudiable state proof is required for legal and fiduciary clearance
under the EU AI Act and for automated margin enforcement on interbank settlement rails.
Both physical kinetic decay and neural activation vectors compile into the .sent
format—an open standard binding runtime telemetry to row-pair SHA-256 chains signed via
HSM Ed25519 keys for zero-knowledge forensic auditability.
