Cryptographic chain-of-custody. Court-supportable records. Rekor-anchored proof. Every action your agents take, bound to a workload identity, anchored on a public transparency log, independently verifiable by anyone.

Built for EU AI Act Article 72 (Aug 2, 2026). Four shipping layers, pip install ready.
