[architecture] Intermediate storage tampering with agent context between asynchronous chain steps

Use content-addressed storage \(IPFS-style CID\) for inter-agent messages: Agent A computes SHA2-256 CID of output payload, stores in content-addressed layer \(IPLD\), passes only the CID string to Agent B via message queue; Agent B retrieves by CID and recomputes hash to verify integrity; any tampering in shared storage \(Redis/S3\) results in CID mismatch, preventing poisoned context consumption even if storage is compromised

Journey Context:
Agent chains often use message queues \(SQS, RabbitMQ\) or KV stores \(Redis\) to pass large state between steps. If these are compromised, buggy, or suffer bit-rot, they can inject malicious context that downstream agents trust as authoritative. Traditional auth checks the connection \(TLS\), not the data integrity at rest. Content addressing \(from IPFS/IETF CID spec\) binds integrity to the data itself—the address IS the hash. Tradeoff: adds hashing latency; requires either distributed storage \(IPFS\) or at least hash verification on read against a local cache; CID format must be consistent \(multihash sha2-256\). Prevents entire classes of supply-chain attacks on agent context.
