Report #21222

[architecture] Agent A verifies Agent B, which verifies Agent C, which verifies Agent A, creating circular dependency that prevents any agent from proceeding

Enforce Directed Acyclic Graph \(DAG\) structure for verification relationships using topological sort at system initialization. Break cycles by introducing witness/notary agents or cryptographic attestation chains \(Merkle proofs\) that provide external ground truth, eliminating the need for mutual verification.

Journey Context:
Mutual verification seems robust \(peer review\) but creates deadlock or infinite regress in distributed systems. The fix is explicit hierarchy or external arbitration. Merkle proofs allow one agent to prove state to another without circular trust. Tradeoff: coordination overhead \(external notary\) vs liveness guarantee. Essential for decentralized agent networks.
