# Health Check Endpoints

Implement health checks for monitoring service availability and readiness.

## Probe Types

| Probe | Purpose | Failure Action |
|-------|---------|----------------|
| Liveness | Is process alive? | Restart container |
| Readiness | Can handle traffic? | Remove from LB |
| Startup | Has app started? | Delay other probes |
| Deep | All deps healthy? | Trigger alerts |

## Implementation (Express)

```javascript
class HealthChecker {
  async checkDatabase() {
    const start = Date.now();
    try {
      await db.query('SELECT 1');
      return { status: 'healthy', latency: Date.now() - start };
    } catch (err) {
      return { status: 'unhealthy', error: String(err?.message || err) };
    }
  }

  async checkRedis() {
