Verification And Replay
Independent verification is the trust backstop. A verifier runs the open replay client against Base mainnet logs. The client downloads the pinned bundle, reconstructs the substrate from accepted patch bytes, re-derives each hidden pack from the revealed epoch secret, runs the same CPU model evaluator, and compares its scores against the on-chain receipts.
Any drift outside the published replay tolerance is a flag. The audit path is open to anyone with chain access and a CPU. Without this layer, "the coordinator scored your patch fairly" would have to be taken on faith, which is exactly the kind of trusted-oracle dynamic the rest of the protocol design avoids.
