The read-only cluster_read tool (and the HUX-12 producer) reach the
Kubernetes API through the kubernetes Service, which kube-proxy DNATs
from the 10.43.0.1 ClusterIP to a control-plane node on 192.168.22.11-13
:6443 - addresses the tenant egress except-block was dropping, so calls
failed with connection-refused. Egress now allows the ClusterIP and
those three apiserver endpoints on 443/6443. RBAC still bounds what is
readable (no Secrets); nothing else about the isolation changes.
