Report #44335

[architecture] Duplicate side-effects when retrying failed multi-agent workflows

Implement content-addressable storage \(Merkle-tree or CID-based\) for intermediate outputs; require agents to check for existing output hashes before execution

Journey Context:
Standard idempotency keys \(UUIDs\) require centralized state management which creates a single point of failure and trust. In distributed agent chains, Agent B cannot trust Agent A's claim that 'this is a retry' without verifying the content hasn't changed. Content-addressing \(using IPFS CIDs or Merkle DAGs\) allows Agent B to verify that the input from Agent A produces the exact same deterministic output without trusting Agent A's metadata. This also enables automatic deduplication across independent agent runs. The tradeoff is computational overhead for hashing and the requirement for deterministic agent outputs \(temperature=0, fixed seeds\).
