HA stores a voice satellite as a pinned LAN IP and never re-resolves; when the LAN renumbers (framework-pt: entry at 192.168.1.241, LAN now 192.168.63.0/24) the speaker silently drops forever. A periodic keeper probes IP-pinned wyoming entries, sweeps the node's local /24s for the satellite's port when one dies, rewrites core.config_entries (HA stopped around the edit so its shutdown flush can't clobber it) and starts HA again.
