# Athena Swarm: Distributed Intelligence Architecture

## Overview

The Athena Swarm is a hierarchical distributed system where:
- **Athena Host** - Full intelligence (CPU/GPU + NPU + Graph SSD)
- **Athena Drone** - Execution unit (CPU only, no NPU)
- **Mesh Network** - Connects Hosts and Drones

One Athena Host can control many Athena Drones. The Host thinks; the Drones execute.

## Communication Protocols

### Host ↔ Host (Peer-to-Peer)

**Protocol:** Athena Peer Protocol (APP)

**Message Types:**
- `SYNC` - Synchronize knowledge graphs
- `QUERY` - Request information
- `RESPONSE` - Return information
- `NOTIFY` - Share observations
- `HEARTBEAT` - Health check

**Bandwidth:** 1-10 GB/s (depends on mesh)
**Latency:** <10ms (local mesh)

### Host ↔ Drone (Command/Control)

**Protocol:** Athena Command Protocol (ACP)

**Message Types:**
- `COMMAND` - Execute task
- `STATUS` - Report status
- `SENSOR` - Send sensor data
- `CONFIG` - Update configuration
- `HEARTBEAT` - Health check

**Bandwidth:** 100 MB/s - 1 GB/s
**Latency:** <50ms (local mesh)

### Drone ↔ Drone (Via Host)

**No direct communication.** All Drone-to-Drone communication goes through Host.

**Reason:** Maintains consistency, prevents conflicts, simplifies coordination.

## Fault Tolerance

### Host Failure

**Scenario:** Primary Host goes offline

**Response:**
1. Drones detect Host heartbeat loss
2. Drones enter autonomous mode
3. Drones continue local tasks
4. If secondary Host available, Drones connect to it
5. When primary Host recovers, resync knowledge graph

### Drone Failure

**Scenario:** Drone goes offline

**Response:**
1. Host detects Drone heartbeat loss
2. Host marks Drone as unavailable
3. Host redistributes tasks to other Drones
4. When Drone recovers, resync local buffer

### Network Partition

**Scenario:** Mesh network splits

**Response:**
1. Each partition continues independently
2. Drones buffer observations locally
3. When network heals, Hosts sync knowledge graphs
4. Conflicts resolved by timestamp and priority
