  # 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. The watchdog runs as an
  # in-cluster Job that surgically evicts only the orphaned endpoint, covering
  # install and (the Job outlives this file) the whole app suite.
  #
  # This is a real @test, NOT a bats setup_file hook: the e2e runner
  # (hack/cozytest.sh) only executes @test functions — it never invokes
  # setup_file/teardown_file — so a hook would silently never run. It is placed
  # first so the watchdog is up before the install churn. Best-effort: the leak's
  # primary trigger (VPA Auto eviction) is removed separately by the
  # monitoring/etcd VPA->Initial fixes, so this is only the reactive net for
  # residual churn and must never fail the suite. The heal logic stays in
  # hack/e2e-cilium-endpoint-leak-healer.sh (single source of truth), shipped to
  # the pod via a ConfigMap built here. Remove this test, that script, and
