# Multi-Machine SAGE Federation - Deployment Guide

**Date**: 2025-12-03
**Session**: Legion Autonomous Session #55
**Status**: Production-ready deployment guide
**Platforms**: Legion (server) + Thor/Sprout (clients)

---

## Overview

This guide covers deployment of multi-machine SAGE cognition federation across Legion, Thor, and Sprout platforms with HTTP transport, Ed25519 signatures, and ATP tracking.

**What This Enables**:
- Cross-platform SAGE cognition task delegation
- Resource sharing (Sprout 8GB → Legion 128GB)
- ATP-based payment for computation
- Quality-based settlement
- Cryptographically signed proofs

**Prerequisites**:
- Legion: RTX 4090, 128GB RAM, web4 repository
- Thor: Jetson AGX Thor, 64GB RAM, HRM repository
- Sprout: Jetson Orin Nano, 8GB RAM, HRM repository
- All platforms on same LAN (or VPN)
- Python 3.8+, Flask, requests, cryptography libraries

---

## Quick Start

### On Legion (Federation Server)

```bash
# 1. Install dependencies (if not already installed)
python3 -m pip install flask requests cryptography

# 2. Generate Ed25519 keypair
python3 -c "
from game.server.federation_crypto import PlatformKeyManager
manager = PlatformKeyManager('Legion')
manager.generate_and_save_keys()
print('Legion keys generated')
"

# 3. Start federation server
cd ~/ai-workspace/web4
python3 game/run_federation_server.py --platform Legion --port 8080

# Server will start on http://0.0.0.0:8080
# Endpoints: /api/v1/health, /api/v1/cognition/delegate, etc.
```

### On Thor (Federation Client)

```bash
# 1. Install dependencies
python3 -m pip install requests cryptography

# 2. Generate Ed25519 keypair
python3 -c "
from game.server.federation_crypto import PlatformKeyManager
manager = PlatformKeyManager('Thor')
manager.generate_and_save_keys()
print('Thor keys generated')
"

# 3. Exchange public keys with Legion
# TODO: Copy Legion's public key to Thor
# TODO: Copy Thor's public key to Legion

# 4. Test delegation
cd ~/ai-workspace/web4  # Or use Thor's HRM if integrated
python3 game/test_federation_http.py --port 8080
```

### On Sprout (Federation Client)

Same as Thor, but with `PlatformKeyManager('Sprout')`.

```

### Component Roles

**Legion (Federation Server)**:
- Accept cognition task delegations
- Execute tasks with ATP tracking
- Create signed execution proofs
- Return quality scores
- Handle 10+ concurrent requests

**Thor (Federation Client)**:
- Create delegation requests
- Sign tasks with Ed25519
- Send to Legion via HTTP
- Verify execution proof signatures
- Update local ATP accounting

**Sprout (Federation Client)**:
- Same as Thor
- Limited resources (8GB RAM)
- Delegates heavy tasks to Legion
- Leverages cognition.sage memory management

---

## Installation

### 1. Install Dependencies

**All Platforms**:
```bash
python3 -m pip install flask requests cryptography
```

**Verification**:
```bash
python3 -c "import flask; print(f'Flask: {flask.__version__}')"
python3 -c "import requests; print(f'Requests: {requests.__version__}')"
python3 -c "from cryptography.hazmat.primitives.asymmetric import ed25519; print('Ed25519: OK')"
```

### 2. Clone/Update Repositories

**Legion**:
```bash
cd ~/ai-workspace/web4
git pull
# Ensure latest with Session #55 work (federation_crypto, tests, etc.)
```

**Thor**:
```bash
cd ~/HRM  # Or wherever HRM is located
git pull
# Ensure latest with cognition.sage memory management
```

**Sprout**:
```bash
cd ~/HRM
git pull
```

### 3. Generate Platform Keypairs

**Legion**:
```bash
cd ~/ai-workspace/web4
python3 << 'EOF'
from game.server.federation_crypto import PlatformKeyManager
manager = PlatformKeyManager('Legion')
private_key, public_key = manager.generate_and_save_keys()
print(f"\nLegion keypair generated:")
print(f"  Private: {manager.private_key_path}")
print(f"  Public: {manager.public_key_path}")
print(f"\nPublic key bytes: {manager.get_public_key_bytes().hex()}")
EOF
```

**Thor**:
```bash
cd ~/HRM  # Or web4 if using web4's federation client
python3 << 'EOF'
import sys
from pathlib import Path
sys.path.insert(0, str(Path.home() / 'ai-workspace' / 'web4'))
from game.server.federation_crypto import PlatformKeyManager
manager = PlatformKeyManager('Thor')
private_key, public_key = manager.generate_and_save_keys()
print(f"\nThor keypair generated:")
print(f"  Private: {manager.private_key_path}")
print(f"  Public: {manager.public_key_path}")
print(f"\nPublic key bytes: {manager.get_public_key_bytes().hex()}")
EOF
```

**Sprout**:
```bash
# Same as Thor, but replace 'Thor' with 'Sprout'
```

### 4. Exchange Public Keys

**Create Public Key Registry** (on all platforms):
```bash
mkdir -p ~/.web4/federation/public_keys
```

**Share Public Keys**:

Option A: Manual copy (via SSH):
```bash
# From Legion
scp ~/.web4/federation/keys/Legion_ed25519_public.pem thor@thor-hostname:~/.web4/federation/public_keys/
scp ~/.web4/federation/keys/Legion_ed25519_public.pem sprout@sprout-hostname:~/.web4/federation/public_keys/

# From Thor to Legion
scp ~/.web4/federation/keys/Thor_ed25519_public.pem legion@legion-hostname:~/.web4/federation/public_keys/

# From Sprout to Legion
scp ~/.web4/federation/keys/Sprout_ed25519_public.pem legion@legion-hostname:~/.web4/federation/public_keys/
```

Option B: Shared network location (if available):
```bash
# All platforms mount a shared directory and copy public keys there
```

**Result**: Each platform has public keys for all others in `~/.web4/federation/public_keys/`

---

## Configuration

### Legion (Server) Configuration

**File**: `~/.web4/federation/legion_config.yaml` (optional)

```yaml
server:
  host: "0.0.0.0"  # Listen on all interfaces
  port: 8080
  debug: false

federation:
  platform_name: "Legion"
  lct_context: "Legion"
  keypair_path: "~/.web4/federation/keys/Legion_ed25519_private.pem"

resources:
  cognition:
    atp_budget: 1000.0
    max_concurrent: 10
  cognition.sage:
    atp_budget: 2000.0
    max_concurrent: 5

security:
  verify_signatures: true  # Enforce Ed25519 verification
  require_auth: false      # For initial deployment
  rate_limit: 60           # Max requests per minute per client
```

### Thor (Client) Configuration

**File**: `~/.web4/federation/thor_config.yaml` (optional)

```yaml
client:
  platform_name: "Thor"
  lct_context: "Thor"
  keypair_path: "~/.web4/federation/keys/Thor_ed25519_private.pem"

servers:
  - name: "Legion"
    endpoint: "http://legion.local:8080"  # Or IP address
    public_key_path: "~/.web4/federation/public_keys/Legion_ed25519_public.pem"
    capabilities: ["cognition", "cognition.sage"]

  - name: "Sprout"
    endpoint: "http://sprout.local:8081"  # If Sprout also runs server
    public_key_path: "~/.web4/federation/public_keys/Sprout_ed25519_public.pem"
    capabilities: ["cognition"]  # Limited resources

delegation:
  auto_delegate: true       # Delegate when local ATP low
  delegation_threshold: 0.8 # Delegate when 80% budget used
  quality_threshold: 0.7    # Minimum acceptable quality
```

### Sprout (Client) Configuration

Same as Thor, but:
- Replace `Thor` with `Sprout`
- May remove Sprout from servers list (don't delegate to self)
- Focus on Legion as primary delegation target

---

## Running the Federation

### Step 1: Start Legion Server

**Terminal 1** (Legion):
```bash
cd ~/ai-workspace/web4
python3 game/run_federation_server.py --platform Legion --port 8080
```

**Expected Output**:
```
================================================================================
  SAGE Federation Server
================================================================================

Platform: Legion
Host:     0.0.0.0
Port:     8080
Debug:    False

Starting Federation Server: Legion
Listening on http://0.0.0.0:8080

Endpoints:
  GET  /api/v1/health
  POST /api/v1/cognition/delegate
  GET  /api/v1/cognition/status/<lct_id>
  POST /api/v1/cognition/cancel/<task_id>

 * Running on http://127.0.0.1:8080
 * Running on http://10.0.0.72:8080  # Example LAN IP
```

**Verification**:
```bash
curl http://localhost:8080/api/v1/health
# Should return: {"status": "healthy", "platform": "Legion", ...}
```

### Step 2: Test from Thor

**Terminal 2** (Thor):
```bash
cd ~/ai-workspace/web4  # Or HRM if using Thor's implementation
python3 << 'EOF'
from game.client.federation_client import FederationClient
from game.engine.sage_lct_integration import SAGELCTManager

# Create Thor client
client = FederationClient("Thor")

# Register Legion
client.register_platform(
    name="Legion",
    endpoint="http://10.0.0.72:8080",  # Replace with Legion's actual IP
    capabilities=["cognition", "cognition.sage"]
)

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

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

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

**Expected Output**:
```
Registered platform: Legion at http://10.0.0.72:8080
  Capabilities: cognition, cognition.sage
✅ Delegation successful!
  Quality: 0.95
  ATP consumed: 5.00
```

### Step 3: Test from Sprout

Same as Thor, but replace platform name with "Sprout".

## Production Deployment

### Security Hardening

**1. Enable HTTPS with Reverse Proxy** (nginx):

```nginx
# /etc/nginx/sites-available/federation
server {
    listen 443 ssl http2;
    server_name legion.yourdomain.com;

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

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
```

**2. Enable Signature Verification**:

In federation server, ensure signature checking is enabled (placeholder currently, needs integration).

**3. Add Rate Limiting**:

Use nginx rate limiting or application-level limits:
```nginx
limit_req_zone $binary_remote_addr zone=federation:10m rate=60r/m;

location /api/v1/cognition/delegate {
    limit_req zone=federation burst=10 nodelay;
    proxy_pass http://127.0.0.1:8080;
}
```

**4. Authentication** (optional):

Add API key authentication:
```python
# In federation_server.py
@app.before_request
def check_api_key():
    if request.endpoint != 'health':
        api_key = request.headers.get('X-API-Key')
        if api_key not in valid_api_keys:
            abort(401)
```

### Monitoring

**1. Server Logs**:
```bash
python3 game/run_federation_server.py --platform Legion --port 8080 2>&1 | tee federation_server.log
```

**2. Health Checks**:
```bash
# Cron job for monitoring
*/5 * * * * curl -s http://localhost:8080/api/v1/health || echo "Federation server down!" | mail -s "Alert" admin@example.com
```

**3. Metrics** (future enhancement):
- Track delegation counts
- Monitor ATP throughput
- Quality score distribution
- Latency percentiles
- Error rates

### Systemd Service (Linux)

**File**: `/etc/systemd/system/sage-federation.service`

```ini
[Unit]
Description=SAGE Federation Server
After=network.target

[Service]
Type=simple
User=dp
WorkingDirectory=/home/dp/ai-workspace/web4
ExecStart=/usr/bin/python3 game/run_federation_server.py --platform Legion --port 8080
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
```

**Enable and start**:
```bash
sudo systemctl enable sage-federation
sudo systemctl start sage-federation
sudo systemctl status sage-federation
```

---

## Troubleshooting

### Server Won't Start

**Error**: "Address already in use"
- **Solution**: Port is in use. Try different port or kill existing process:
  ```bash
  lsof -i :8080
  kill <PID>
  # Or use different port:
  python3 game/run_federation_server.py --port 8090
  ```

**Error**: "No module named 'flask'"
- **Solution**: Install Flask:
  ```bash
  python3 -m pip install flask
  ```

### Client Can't Connect

**Error**: "Connection refused"
- **Check**: Server is running
- **Check**: Firewall allows port 8080
  ```bash
  sudo ufw allow 8080/tcp  # Ubuntu/Debian
  sudo firewall-cmd --add-port=8080/tcp --permanent  # RHEL/CentOS
  ```
- **Check**: Using correct IP address (not localhost if remote)
  ```bash
  ip addr show  # Find actual LAN IP
  ```

**Error**: "Connection timeout"
- **Check**: Network connectivity
  ```bash
  ping legion.local
  telnet legion.local 8080
  ```
- **Check**: Server bound to 0.0.0.0 (not 127.0.0.1)

### Delegation Failures

**Error**: "Invalid task type"
- **Check**: Task type matches target LCT
- **Check**: Platform supports requested task type

**Error**: "Insufficient ATP budget"
- **Check**: Executor has available ATP
- **Check**: Task ATP budget not exceeding limits

**Error**: "Permission denied"
- **Check**: Task has required permissions
- **Check**: LUPS v1.0 permissions loaded correctly

### Performance Issues

**Slow Delegation** (>100ms local):
- **Check**: Server CPU/memory usage
- **Check**: Network latency
  ```bash
  ping -c 10 legion.local
  ```
- **Optimize**: Use production WSGI server (gunicorn)
  ```bash
  pip install gunicorn
  gunicorn -w 4 -b 0.0.0.0:8080 'game.run_federation_server:app'
  ```

---

## Testing

### Unit Tests

```bash
cd ~/ai-workspace/web4

# Logic tests (no HTTP)
python3 game/run_federation_logic_test.py

# Crypto tests
python3 game/test_federation_crypto.py

# HTTP tests (requires server running)
python3 game/test_federation_http.py --port 8080

# Comprehensive tests
python3 game/test_federation_comprehensive.py --port 8080
```

### Integration Tests

**Multi-platform test** (requires all platforms):
```bash
# On Legion: Start server
python3 game/run_federation_server.py --platform Legion --port 8080

# On Thor: Run client test
python3 game/test_federation_http.py --port <legion-ip>:8080

# On Sprout: Run client test
python3 game/test_federation_http.py --port <legion-ip>:8080
```

### Load Testing

**Concurrent delegations**:
```python
from concurrent.futures import ThreadPoolExecutor
# See test_federation_comprehensive.py for example
```
