Report #97469

[architecture] Audit logs capture prompts but cannot reconstruct which agent did what

Log a tamper-evident chain of custody for every output: agent identity, input hash, tool calls, output hash, confidence, and validation result. Store hashes outside the agent's write path.

Journey Context:
Logging prompts is insufficient for forensics in multi-agent systems because the same prompt can be reused across agents and outputs mutate as they flow. A proper audit trail treats each agent's output as an artifact with a stable hash, records the exact inputs and tools that produced it, and links it to the previous artifact in the chain. The log append-only store must be outside the agents' control; otherwise a compromised agent can rewrite history. This is essential not just for security but for debugging why a chain produced a wrong answer.
