The mdns-relay NAD gets the tuning plugin from shelly-manager-iot (accept_ra=0, autoconf=0 on net1). Without it the IPv6 relay sends to the home-assistant-mdns Service via net1 with an IoT source address and HA's CNP drops every datagram. The pod annotation bump re-attaches net1.

sbr confines only the DHCP (IPv4) routes. net1 still takes a SLAAC address
and an RA default route, so socat-ipv6 sent every relayed datagram out the
IoT VLAN with source fd02:30::…; it came back through the UDM and HA's
CNP dropped it (37k POLICY_DENIED to home-assistant:5353 in 24 h). No IPv6
mDNS announcement reached HA. Same tuning as shelly-manager-iot. The
annotation bump re-attaches net1 with the new NAD.
