The Trump EO on PQC doesn't mandate migration of all systems by 2031. High-value assets and high-impact systems: PQC digital signatures by Dec 31, 2031. Everything else: different timeline. For institutional custody — the verification layer is what makes migration auditable. Not just deploying PQC. Proving it was verified correctly. 200/200 NIST ML-DSA-87 vectors passed. qubexsentinel.com/verify

The post-quantum conversation focuses almost entirely on signing infrastructure. The verification layer — the independently auditable proof that a signature was produced correctly — is the overlooked half.
