  "completed_tasks": 0
}
```

---

### Thor (Federation Client)

**Hardware**: Jetson AGX Thor, 64GB RAM
**Role**: Federation client (delegates to Legion)
**Dependencies**: requests

**Install Dependencies**:
```bash
pip install requests
```

**Configure** (create `~/HRM/sage/config/federation.yaml`):
```yaml
client:
  platform_name: "Thor"
  lineage: "dp"

servers:
  - name: "Legion"
    endpoint: "http://legion.local:8080"
    capabilities: ["cognition", "cognition.sage"]
```

**Test Delegation**:
```python
from game.client.federation_client import FederationClient
from game.engine.sage_lct_integration import SAGELCTManager

# Create client
client = FederationClient("Thor")
client.register_platform(
    name="Legion",
    endpoint="http://legion.local:8080",
    capabilities=["cognition", "cognition.sage"]
)

# Create local identity
manager = SAGELCTManager("Thor")
identity, state = manager.create_sage_identity("dp", False)

# Delegate task
proof, error = client.delegate_task(
    source_lct=identity.lct_string(),
    task_type="cognition",
    operation="perception",
    atp_budget=50.0,
    target_platform="Legion"
)

if proof:
    print(f"✅ Delegation successful!")
    print(f"  Quality: {proof.quality_score:.2f}")
    print(f"  ATP consumed: {proof.atp_consumed}")
else:
    print(f"✗ Delegation failed: {error}")
```

---

### Sprout (Federation Client)

**Hardware**: Jetson Orin Nano, 8GB RAM
**Role**: Federation client (delegates to Legion/Thor)
**Dependencies**: requests

**Install Dependencies**:
```bash
pip install requests
```

**Configure** (create `~/.web4/federation/config.yaml`):
```yaml
client:
  platform_name: "Sprout"
  lineage: "dp"

servers:
  - name: "Legion"
    endpoint: "http://legion.local:8080"
    capabilities: ["cognition", "cognition.sage"]
  - name: "Thor"
    endpoint: "http://thor.local:8082"
    capabilities: ["cognition", "cognition.sage"]
```

**Test Delegation**: Same as Thor example above

---

## Network Configuration

### Local Network (Recommended for Testing)

**Assumptions**:
- All platforms on same LAN
- mDNS/Avahi for `.local` hostname resolution
- Firewall allows HTTP traffic on ports 8080-8082

**Verify Connectivity**:
```bash
# From Thor or Sprout
ping legion.local
curl http://legion.local:8080/api/v1/health
```

### Internet Deployment (Production)

**Considerations**:
1. **TLS/HTTPS**: Use reverse proxy (nginx, caddy)
2. **Authentication**: Add API keys or OAuth
3. **Rate Limiting**: Prevent DoS attacks
4. **Monitoring**: Log all delegations and ATP transfers

**Example nginx config**:
```nginx
server {
    listen 443 ssl;
    server_name legion.example.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    location /api/ {
        proxy_pass http://127.0.0.1:8080/api/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
```

---

## Testing

### Test 1: Health Check

**Command**:
```bash
curl http://legion.local:8080/api/v1/health
```

**Expected**:
```json
{
  "status": "healthy",
  "platform": "Legion",
  "active_tasks": 0,
  "completed_tasks": 0
}
```

### Test 2: Task Delegation (curl)

**Command**:

curl http://legion.local:8080/api/v1/cognition/status/lct%3Aweb4%3Aagent%3Adp%40Legion%23consciousness
```

**Expected**:
```json
{
  "success": true,
  "status": {
    "lct_id": "lct:web4:agent:dp@Legion#cognition",
    "task": "cognition",
    "atp_spent": 5.0,
    "atp_budget": 1000.0,
    "atp_remaining": 995.0,
    "active_tasks": 0,
    "is_active": true
  },
  "error": null
}
```

### Test 4: Multi-Platform Federation (Python)

**On Thor**:
```bash
cd ~/ai-workspace/web4

# Ensure Legion server is running first
# Then run multi-machine test
python3 game/run_multi_machine_federation_test.py
```

**Expected** (if Legion server running):
```
================================================================================
MULTI-MACHINE SAGE FEDERATION TEST
================================================================================

...

✅ ALL TESTS PASSED

Conclusion:
  - Federation server operational
  - Task delegation working
  - ATP tracking accurate
  - Quality scoring functional
  - Remote status checking operational

Ready for: Multi-machine deployment (Legion, Thor, Sprout)
```

---

## Monitoring

### Server Logs

**Legion** (server logs):
```bash
tail -f /tmp/federation_legion.log  # If configured
```

**Look for**:
- `POST /api/v1/cognition/delegate` - Incoming delegations
- `Task <id> executed` - Successful executions
- `ATP consumed: <amount>` - ATP tracking
- `Quality score: <score>` - Quality validation

### ATP Tracking

**Query Cognition State**:
```python
from game.server.federation_api import FederationAPI

api = FederationAPI("Legion")
status = api.get_status("lct:web4:agent:dp@Legion#cognition")

print(f"ATP spent: {status['atp_spent']}")
print(f"ATP remaining: {status['atp_remaining']}")
print(f"Active tasks: {status['active_tasks']}")
```

### Quality Metrics

**Track Delegation Quality**:
```python
from game.server.federation_api import FederationAPI

api = FederationAPI("Legion")

# Get all completed tasks
for task_id, proof in api.completed_tasks.items():
    print(f"Task {task_id}: quality={proof.quality_score:.2f}, ATP={proof.atp_consumed}")
```

---

## Troubleshooting

### Issue: "Connection refused"

**Symptoms**:
```
requests.exceptions.ConnectionError: Failed to connect to http://legion.local:8080
```

**Solutions**:
1. Verify Legion server is running: `curl http://legion.local:8080/api/v1/health`
2. Check firewall: `sudo ufw allow 8080/tcp`
3. Check network connectivity: `ping legion.local`
4. Use IP address instead of hostname: `http://192.168.1.100:8080`

### Issue: "Module not found: flask"

**Symptoms**:
```
ModuleNotFoundError: No module named 'flask'
```

**Solution**:
```bash
pip install flask
# Or for system-wide:
sudo pip3 install flask
```

### Issue: "Invalid task format"

**Symptoms**:
```json
{
  "success": false,
  "error": "Invalid task format: ..."
}
```

**Solutions**:
1. Verify JSON format matches FederationTask schema
2. Check all required fields present
3. Ensure LCT identity format correct: `lct:web4:agent:lineage@context#task`
4. Verify task_type matches target LCT task

### Issue: "Insufficient ATP budget"

**Symptoms**:
```json
{
  "success": false,
  "error": "Insufficient ATP budget. Required: 100.0, Available: 50.0"
}
```

**Solutions**:
1. Check executor ATP budget: `/api/v1/cognition/status/<lct_id>`
2. Reduce task ATP budget
3. Wait for ATP budget to reset (if periodic)
4. Use cognition.sage (2000 ATP vs 1000 ATP)

## Performance Optimization

### Server Tuning

**Increase concurrent connections** (Legion):
```python
# In run_federation_server.py
server.app.config['MAX_CONNECTIONS'] = 100
server.app.config['TIMEOUT'] = 120
```

**Use production WSGI server**:
```bash
pip install gunicorn
gunicorn -w 4 -b 0.0.0.0:8080 game.server.federation_server:app
```

### Client Optimization

**Connection pooling**:
```python
import requests
session = requests.Session()
# Reuse session for multiple requests
```

**Async delegation** (for concurrent tasks):
```python
import asyncio
import aiohttp

async def delegate_async(client, task):
    # Use aiohttp for async HTTP
    pass
```

---

## Security Considerations

### Current Status (Session #54)

- ✅ Permission validation (task type, operation)
- ✅ ATP budget enforcement
- ✅ Resource limit checking
- ⚠️ Ed25519 signatures (placeholder - not enforced)
- ⚠️ No TLS/HTTPS (use reverse proxy)
- ⚠️ No authentication (add API keys)

### Future Enhancements

**Ed25519 Signature Verification**:
```python
# In FederationAPI.delegate_consciousness_task():
from cryptography.hazmat.primitives.asymmetric import ed25519

# Verify task signature
try:
    public_key.verify(signature, task.to_signable_dict())
except Exception:
    return (None, "Invalid signature")
```

**API Key Authentication**:
```python
@app.before_request
def verify_api_key():
    api_key = request.headers.get('X-API-Key')
    if api_key != expected_api_key:
        return jsonify({"error": "Unauthorized"}), 401
```

**Rate Limiting**:
```python
from flask_limiter import Limiter

limiter = Limiter(app, key_func=get_remote_address)

@app.route('/api/v1/cognition/delegate', methods=['POST'])
@limiter.limit("60/minute")
def delegate():
    ...
```
