# k8s-event-exporter — watches Kubernetes Events and logs them to stdout as
# structured JSON. Promtail tails the logs and ships them to Loki with the
# label app=kubernetes-event-exporter. The Hermes agent queries them with LogQL:
#   {app="kubernetes-event-exporter"} |= "BackOff"
#
# This avoids giving the agent any k8s API token for events — the exporter
# has its own narrow read-only SA, and the agent only talks to Loki.
