Report #24842

[architecture] Agents dispute what was sent/received; no tamper-proof log exists to reconcile 'Agent A said X' vs 'Agent B received Y'

Implement a Merkle tree log \(similar to Certificate Transparency\) for all inter-agent messages: each message includes a hash of the payload and the previous message's hash, forming an immutable chain. Agents periodically checkpoint roots to a separate tamper-resistant store \(e.g., signed by a notary\).

Journey Context:
Standard logging is mutable and can't prove that Agent A actually sent message X at time T. When debugging multi-agent failures, agents blame each other \('I sent the right schema, you parsed it wrong'\). Simple checksums in logs don't prevent tampering or logging gaps. Merkle trees \(RFC 6962\) provide cryptographic inclusion proofs: Agent B can prove to an auditor 'Agent A sent me X at 12:00' by showing the path to the root without revealing all other messages. This is essential for compliance \(finance, healthcare\) and post-incident analysis. The alternative—blockchain—is overkill and too slow for high-throughput agent chatter.
