every agent action signed, chained, and anchored. change one record and verification fails at that exact position.
logs can be rotated. records can be edited. when a regulator, a court, or a customer asks what your ai agent actually did, the only question that matters is whether the record you show today is the record created at the moment it happened.
syenis that proof. every agent action, human approval, and automated decision is signed with ed25519, chained to the record before it with sha-256, and anchored daily to digicert’s rfc 3161 trusted timestamp authority.
who the agent was acting for.
what it was cleared to do.
what it actually did, and when.
verification fails at that exact position.
the gap in the chain is detected.
the fabricated entry is rejected.
no log rotation, no admin override, no way to alter the chain without detection.
article 12 of the eu ai act requires automatic record keeping for high-risk ai systems. the record has to be created while the system runs, and it has to hold up when someone checks it. a rotated log file does not settle that question. a signed chain does.
every event in a syen chain is signed at the moment it happens and linked to the event before it. when the auditor arrives, the record verifies with openssl, and any gap or edit fails at the exact position it happened. teams tracking the regulation itself use the regulatory change management record, and the know your agent page covers how agent identity fits the same chain.
your auditor checks the entire chain with openssl. no access to your systems. no access to ours.
