+The server uses host networking for LAN multicast and IPv6 connectivity to
+Matter devices. It has no node selector, fixed listen address, or fixed
+interface name; Kubernetes can reschedule it with the same CephFS claim.
+MetalLB allocates a LAN address for the WebSocket/dashboard Service. That
+address covers API access, not Matter discovery or device traffic: the
+node running the controller still needs working LAN IPv6 routes to the OTBR.
+The cluster's Cilium pod network is IPv4-only, so a LoadBalancer Service

+border router; Matter Server does not create another Thread network.
+There is no public ingress. A single controller restarts during rescheduling;
+this is recovery with preserved state, not uninterrupted active-active service.
 
 The MikroTik-managed `app-otbr` container requires these startup sysctls in
 its own network namespace: `net.ipv6.conf.all.forwarding=1`,
