# Headless Service: gives the StatefulSet pod a stable DNS name
# (tidaldb-0.tidaldb.tidaldb.svc.cluster.local) and backs in-cluster clients.
# Headless (clusterIP: None) is the right default for a single stateful pod;
# readiness gating still applies, so the pod drops out of DNS A-records while
# draining. Front it with an Ingress/Gateway for external traffic — do NOT
# expose the metrics port (9091) outside the cluster (it is unauthenticated).
