Report #35774

[architecture] Tampering and hallucination of intermediate agent outputs passed through untrusted channels or caches

Implement semantic verification using content-addressable storage \(Merkle DAGs or Merkle trees\): hash agent outputs and verify the root hash against expected values before processing, using Merkle proofs to verify subsets without downloading full content

Journey Context:
JSON Schema validation catches syntax errors but not content substitution, man-in-the-middle tampering, or cache corruption. Content addressing \(where hash = identifier\) makes tampering evident because modifying content changes the address. Merkle trees allow efficient verification that specific fields haven't been altered without downloading the entire payload \(useful for large outputs\). Tradeoff: adds computational overhead for hashing and storage complexity for the Merkle tree structure. Alternative is digital signatures \(asymmetric crypto\) which provide non-repudiation but require complex key management and PKI; content addressing provides integrity with simpler operational properties and can be combined with signatures for authorship verification. Essential when agents traverse organizational boundaries or use shared storage.
