H33-74Chain-Portable Evidence
"Producing operational evidence years after the system that produced it was replaced."
Original post-quantum-signed proofs verified directly without operator infrastructure.
01
Litigation evidence with cryptographic integrity from creation
Authorization chains, approval decisions, and policy applications are bound to the moment they occurred. Discovery answers stop depending on the system being there.
02
Regulator inquiry response with original proofs
Years after the events, the original PQ-signed proofs are produced. The regulator verifies them directly. No reconstruction from operator memory.
03
D&O risk reduction through verifiable governance
Board decisions, committee actions, signing authority chains all produce cryptographically verifiable evidence. Each governance act is independently audit-grade.
04
Evidence longevity through the quantum transition
PQ signatures survive Q-Day. Evidence produced today remains verifiable after quantum-capable adversaries exist.
