[architecture] Assuming all agents in a swarm are honest

If agents can be compromised or malicious, use Byzantine fault-tolerant consensus \(PBFT or BFT variants\) and cryptographic message authentication.

Journey Context:
Standard consensus assumes crash-stop failures, not agents that lie or collude. In open or delegated swarms, a single Byzantine agent can feed inconsistent data to different peers. PBFT handles up to f faulty agents among 3f\+1 total and uses signed messages to detect equivocation. The tradeoff is higher message complexity and latency, so only pay it when trust boundaries are real.
