Report #53889

[architecture] Inability to reconstruct multi-agent decision chains or detect tampering in post-hoc audits

Log all inter-agent messages to a Merkle DAG using content addressing \(SHA-256\); link each message to parent message IDs forming an immutable, tamper-evident audit trail with cryptographic integrity guarantees.

Journey Context:
Debugging multi-agent failures requires knowing exactly what Agent A output to Agent B. Traditional logs can be altered or truncated. Content-addressed storage \(like a Merkle DAG\) means the hash of the content is the lookup key; tampering changes the hash, breaking the chain. Each message references parent hashes, forming a directed acyclic graph. Tradeoff: storage overhead and query complexity vs audit integrity. Essential for regulated environments \(finance, healthcare\) where non-repudiation is required.
