- Byzantine fault tolerance is required (untrusted or unreliable agents)

- State synchronization across distributed agent swarms

- Conflict-free data merging in concurrent operations

## Protocols

| Protocol | Use Case | Fault Tolerance | Complexity |

|----------|----------|-----------------|------------|

| Raft | Leader-based consensus, ordered log | Crash faults (f < n/2) | Medium |

| Byzantine | Untrusted agents, adversarial conditions | Byzantine faults (f < n/3) | High |

| Gossip | Eventual consistency, state propagation | Partition tolerant | Low |

| CRDT | Conflict-free replicated data types | Always convergent | Low |

## Weighted Voting

- Queen agents: 3x weight multiplier

- Worker agents: 1x weight

- Configurable consensus threshold (majority, supermajority, unanimous)

## Agents Used

- `agents/swarm-coordinator/` - Protocol orchestration

- `agents/strategic-queen/` - Weighted voting leadership
