Post-Quantum Audit-Root Anchoring to a Public Proof-of-Work Chain.

Anchors the post-quantum AI-audit root to a public proof-of-work chain. 19 claims.

Periodically computes a Merkle root over a sovereign attestation chain's sealed post-quantum audit records and publishes only that fixed-size fingerprint to a public proof-of-work chain through a timestamp-aggregation proof. The sovereign chain gains an external immutable witness without any operator data leaving it, and offline verification follows a record to the root to the public-chain inclusion proof.
