  # (cilium/cilium#38313 class): a deleted pod's endpoint is orphaned in the
  # agent's registry, IPAM re-hands its IP to a new pod, and the agent then
  # rejects the new sandbox with "IP <X> is already in use" until an agent
  # restart — wedging pods across install AND the app suite and failing
  # unrelated PRs. The watchdog surgically evicts only the orphaned endpoint.
  #
  # It runs as an in-cluster Job (not a bats-scoped background process, which
  # died at this file's teardown_file — before any app test ran — and left the
  # app-phase leak unhealed). Bound to the cluster, it covers every later test
  # step too. The heal logic stays in hack/e2e-cilium-endpoint-leak-healer.sh
  # (single source of truth) and is shipped to the pod via a ConfigMap built
  # from it here. Remove together with that script and
