Janus: Evidence-Before-Effect Sagas and Offline-Verifiable Provenance for Agentic LLMs
Janus is a system designed to fix an audit gap in agentic LLMs by ensuring evidence precedes action. It implements a signed, hash-chained log where proposals and verdicts are recorded durably before any effect is released. This creates verifiable provenance, preventing unauthorized actions by tying approvals directly to specific proposals.
