Report #27400

[architecture] Undetected tampering with intermediate agent outputs in distributed chain

Chain cryptographic hashes \(SHA-256\) of outputs in Merkle tree structure; each agent appends output hash \+ Ed25519 signature to growing chain; verify chain integrity at final aggregation point; use TEE \(Trusted Execution Environment like Intel SGX or AWS Nitro Enclaves\) for high-sensitivity agents to attest execution integrity

Journey Context:
Simple HTTPS protects in-transit data, but not storage or processing integrity. Verifiable computation ensures audit trail. Pattern: Append-only log per agent chain \(similar to Certificate Transparency logs\). Tradeoff: computational overhead \(~1-5ms per hash\). For regulatory compliance \(finance/healthcare\), TEE provides hardware-backed attestation that agent code hasn't been tampered with.
