## 🎯 Key Features

### Security-First Approach
- **Automated vulnerability scanning** with cargo audit and cargo geiger
- **Auditable binaries** for regulatory compliance
- **Digital signatures** for deployment integrity
- **7-year audit retention** for regulatory requirements

### Performance Validation
- **Sub-30μs latency** validation for trading engine
- **100K+ ops/sec** throughput verification
- **P95/P99 monitoring** with HDR histograms
- **Automated rollback** on performance degradation

### Deployment Strategies
- **Canary Deployment**: 1% traffic with gradual rollout
- **Blue-Green Deployment**: Instant zero-downtime switching
- **Emergency Rollback**: Sub-60 second recovery
- **Validate-Only Mode**: Pre-deployment verification

### Compliance & Monitoring
- **Real-time health checks** every 5 seconds
- **Comprehensive metrics** collection and analysis
- **Regulatory compliance** reporting (SOC2, ISO 27001, MiFID II)
- **Digital audit trail** with cryptographic integrity

## 🚀 Quick Start

### 1. Configure Secrets

Set these secrets in your GitHub repository:

```bash
GITHUB_TOKEN                 # Required for Actions
FOXHUNT_ALERT_WEBHOOK       # Slack/Teams alerts
DATABENTO_API_KEY           # Market data access (Databento)
BENZINGA_API_KEY            # News & sentiment access (Benzinga)
GRAFANA_ADMIN_PASSWORD      # Monitoring access
```

### 2. Deploy to Staging

Push to `staging` branch to trigger automated staging deployment:

```bash
git checkout staging
git merge main
git push origin staging
```

### 3. Deploy to Production

#### Automatic (Canary)
Push to `production` branch:

```bash
git checkout production
git merge staging
git push origin production
```

#### Manual Deployment
Use GitHub Actions workflow dispatch:
1. Navigate to Actions → "Foxhunt HFT CI/CD Pipeline"
2. Click "Run workflow"
3. Select deployment strategy and parameters

### 4. Monitor Deployment

```bash
# Real-time monitoring
/opt/foxhunt/deployment/scripts/deployment-monitoring.sh --duration 300

# Check service health
curl http://localhost:8080/health

# View performance metrics
curl http://localhost:8080/metrics | grep latency
```

## 🔧 Configuration

### Performance Thresholds

Customize in `deployment/config/production.toml`:

```toml
[performance]
max_latency_us = 30          # Trading latency threshold
min_throughput_ops = 100000  # Minimum throughput requirement
validation_timeout = 300     # Test duration

[deployment]
strategy = "canary"          # canary, blue-green, validate-only
canary_percentage = 1.0      # Initial canary traffic
```

### Alert Thresholds

```toml
[monitoring]
alert_threshold_cpu = 80     # CPU alert threshold
alert_threshold_memory = 8192 # Memory alert threshold (MB)
health_check_interval = 5    # Health check frequency
```

## 🚨 Emergency Procedures

### Emergency Rollback

For critical production issues:

```bash
sudo /opt/foxhunt/deployment/scripts/emergency-rollback.sh \
  --reason "Critical issue detected" \
  --force
```

### Service Restart

```bash
# Restart specific service
sudo systemctl restart foxhunt-core

# Restart all services
for service in foxhunt-{core,tli,ml,risk,data}; do
  sudo systemctl restart $service
done
```

## 📊 Monitoring Dashboards

## 🛠️ Troubleshooting

### Common Issues

| Issue | Diagnosis | Resolution |
|-------|-----------|------------|
| Deployment Failure | Check logs: `tail -f /home/jgrusewski/Work/foxhunt/logs/deployment-*.log` | Verify health checks, rollback if needed |
| Performance Issues | Monitor: `/opt/foxhunt/deployment/scripts/deployment-monitoring.sh --once` | Check resources, consider rollback |
| Health Check Failures | Service logs: `journalctl -u foxhunt-core -f` | Fix configuration, restart services |

### Log Locations
- **Deployment**: `/home/jgrusewski/Work/foxhunt/logs/`
- **Services**: `/var/log/foxhunt/`
- **Load Balancer**: `/var/log/nginx/foxhunt_*.log`
