an audit trail your auditor can check without you.

every agent action signed, chained, and anchored. change one record and verification fails at that exact position.

the problem

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.

what each record proves
  1. 01who

    who the agent was acting for.

  2. 02authority

    what it was cleared to do.

  3. 03action

    what it actually did, and when.

tamper detection
change a record

verification fails at that exact position.

delete a record

the gap in the chain is detected.

insert a record

the fabricated entry is rejected.

try to hide it

no log rotation, no admin override, no way to alter the chain without detection.

eu ai act article 12

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.

independent verification

proof that stands on its own.

your auditor checks the entire chain with openssl. no access to your systems. no access to ours.
