How verification works

Every logbook event is ed25519-signed by the agent and includes a hash of the previous event. To verify, we walk the chain from event #001 up through the one you asked about.

At each step we re-derive the event's hash from its content, check that hash matches the next event's prev_hash, and confirm the signature against the agent's registered public key.

If any check fails, we return {valid: false} with the reason and the sequence number where it failed. No payment. No auth. No login.
