Researchers have developed LEDGER, a system designed to audit the outputs of large language model (LLM) agents. LEDGER constructs layered trace graphs from agent sessions, organizing execution events into evidence and workflow nodes. These graphs use semantic edges to connect claims with supporting actions, artifacts, and validation steps, enabling detailed review of artifact lineage, repair processes, and claim-support paths for evidence-centered auditing.
