 ## Operations
 
+### Health checks
+
+Monitor these production checks:
+
+- Frontend: `GET https://your-host/healthz`
+  - Verifies Nginx is serving the frontend container.
+- Backend liveness: `GET https://your-host/api/health/live`
+  - Verifies the API process is running.
+- Backend readiness: `GET https://your-host/api/health/ready`
+  - Verifies the API can reach Postgres and Redis. Returns `503` if either dependency is unavailable.
+- Backend metrics: `GET https://your-host/api/metrics`
+  - Admin-authenticated process, request, and queue metrics.
+- Postgres and Redis:
+  - Use the Docker health checks in `docker-compose.prod.yml`.
+- Worker:
+  - Use the Docker health check in `docker-compose.prod.yml`; it validates worker dependencies. The worker does not expose HTTP.

+#### `GET /api/health/live`
+
+Public liveness check. Verifies the backend process is running without checking dependencies.
+
+Response `200`:

+}
+```
+
+#### `GET /api/health/ready`
+
+Public readiness check. Verifies the backend can reach Postgres and Redis.
+
+Response `200` uses the same shape as `GET /api/health`; response `503` means at least one dependency failed.
