Not reproducible with curl or EventSource. | Code-reviewed; guard is passive (drops non-critical events). No risk if untriggered. | +| **DB probe 3s timeout** | Requires a PostgreSQL instance that accepts connections but delays `SELECT 1` beyond 3 seconds. Cannot simulate without network shaping tools. | `Promise.race` implementation is standard pattern; timeout fires correctly in unit-test-like conditions. | +| **MIG auto-healing on 503** | Requires health check to return 503 three consecutive times. Intentionally crashing the container tests MIG recreation but not the health→503 path specifically. | GCP MIG auto-healing is a platform feature with its own SLA. Our job is returning 503 on degraded state — verified via code review. | +| **Dockerfile HEALTHCHECK mismatch** | `--timeout=5s` in Dockerfile vs `timeout_sec: 10` in service.yaml. The Dockerfile HEALTHCHECK is used by Docker (local/COS), while service.yaml configures the GCE health check. They're independent. | Not a bug — different probes for different layers.
