The au-syd1 edge proxy runs on a hand-managed LXD container outside the cluster, with no HA and no shared config source.
- Add `apps/base/haproxy/`: 3 replicas behind the DMZ LoadBalancer 198.18.199.1, config from a ConfigMap, wildcard certs from reflected secrets.
- Keep source IPs via `externalTrafficPolicy: Local`; `sessionAffinity: ClientIP` stands in for the stick-table peers a Deployment cannot name.
- Drain on shutdown: `hard-stop-after 2m`, a preStop SIGUSR1 soft-stop, 150s grace.
- Bind the stats listener to 127.0.0.1 so it is port-forward only.
- Register the app in the platform project and ApplicationSet.
