Report #58837

[architecture] Undetected tampering with intermediate agent outputs in audit logs

Log every inter-agent payload to a Merkle Tree \(Certificate Transparency style\); each agent receives a Signed Tree Head \(STH\) and inclusion proof, enabling cryptographic verification that logs are append-only and unaltered.

Journey Context:
In regulated multi-agent systems \(finance, healthcare\), you must prove an audit trail wasn't tampered with after the fact. Simple signed logs don't detect deletion. Merkle trees provide cryptographic transparency: any fork or rewrite breaks the hash chain. Agents verify inclusion proofs at handoff time. Trade-off: significant storage and latency for tree maintenance, requires centralized or consensus-based log server.
