# Platform alerts that are false positives on a single-control-plane cluster.
# Dropped via an AlertRelabelConfig (monitoring.openshift.io/v1), so they never
# reach Alertmanager. Alerts are matched by exact alertname.
#
# KubeCPUOvercommit / KubeMemoryOvercommit: the HA branch of these rules assumes
# the cluster survives losing its largest node. With one control-plane node plus
# smaller workers, that node is master-0 — losing it loses the cluster anyway.
