/etc/foxhunt/certs/
  ├── ca.crt                  # Root CA
  ├── api_gateway.{key,crt}   # API Gateway
  ├── trading_service.{key,crt}
  ├── backtesting_service.{key,crt}
  ├── ml_training_service.{key,crt}
  └── client.{key,crt}        # mTLS clients
```

**Vault Integration**:
```bash
# Store secrets in Vault
vault kv put secret/foxhunt/jwt JWT_SECRET="..."
vault kv put secret/foxhunt/db DATABASE_URL="..."
vault kv put secret/foxhunt/redis REDIS_URL="..."
```

#### 5. Service Deployment (Complete Configuration)

**Build Release Binaries**:
```bash
# Clean build with LTO and native CPU targeting
RUSTFLAGS="-C target-cpu=native" cargo build --release --workspace

# Strip binaries
strip target/release/{trading_service,backtesting_service,ml_training_service,tli}
```

**SystemD Service Files** (all 3 services):

- Backtesting Service: Standard configuration
- ML Training Service: GPU support, model cache

**Environment Configuration**:
- Trading Service: Database, Redis, JWT, Kill Switch, TLS
- Backtesting Service: Database, gRPC, TLS (optional based on Wave 74)
- ML Training Service: Database, S3, GPU, Model Cache

**Service Startup**:
```bash
# Enable services (auto-start on boot)
sudo systemctl enable foxhunt-{trading,backtesting,ml-training}

# Start services (dependency order)
sudo systemctl start foxhunt-trading
sleep 5  # Wait for initialization
sudo systemctl start foxhunt-backtesting
sudo systemctl start foxhunt-ml-training
```

#### 6. Health Validation (Automated)

**Comprehensive Health Check** (12 checks):

default_pool_size = 20
```

**Redis Memory Optimization**:
```bash
# LFU eviction policy
redis-cli CONFIG SET maxmemory-policy allkeys-lfu
```

#[tokio::main(worker_threads = 16)]  // Adjust based on CPU cores
async fn main() -> Result<()> { ... }
```
