         <li><em>Chain Integrity:</em> Verify the SHA-256 hash link between all checkpoints. Any break invalidates the entire Evidence Packet. The Verifier MUST set the verdict to invalid (4). The warnings field SHOULD include the checkpoint sequence number where the break was detected.</li>
         <li><em>Temporal Order:</em> For each process-proof, recompute Argon2id from the declared seed to obtain state_0, then verify sampled Merkle proofs against the committed root (process-proof key 4, merkle-root). Verify that claimed-duration is within [0.5x, 3.0x] of the expected wall-clock time for the declared proof-params on reference hardware (defined as a system with DDR4 memory providing approximately 25 GB/s sustained bandwidth). Expected times are defined in <xref target="PoP-Protocol"/>, Mandatory SWF Parameters section.</li>
         <li><em>Entropy Threshold:</em> Independently estimate entropy from the jitter-binding intervals array using a standard entropy estimator (e.g., NIST SP 800-90B most common value estimator). Verify the independent estimate meets or exceeds 3.0 bits per inter-keystroke interval. The Attester's self-reported entropy-estimate field MUST NOT be relied upon. Low-entropy segments (below threshold) MUST be flagged as "Non-Biological."</li>
