My previous commit staged the whole kustomization file and swept in the
in-flight netbox lines, which I had said I would keep out. Those reference
infra/envoy-gateway/netbox/, which is untracked, so ArgoCD could not render
the app at all:
kustomize build failed: accumulating resources from
'netbox/netbox-certificate.yaml': no such file or directory
That left envoy-gateway-config unable to load target state, so the orphaned
listener cleanup never applied. The running gateways were unaffected.
Commenting the two entries keeps the work visible in place and makes it a
two line uncomment once infra/envoy-gateway/netbox/ is committed.
