 > **Note (GRO-1544):** Health endpoint registered on `api` basePath before auth middleware at `/api/health`. The old path `/health` was incorrect (routed to web pod via HTTPRoute `/*` rule).
-> **Note (GRO-2678):** `/api/readyz` is a separate DB-touching endpoint for monitoring. It is intentionally NOT used for K8s liveness/readiness probes — those remain DB-less to avoid pod cycling on transient DB blips.
