A from:mesh provider is announced (per 018's fix) at the node's private-network
name, but its port is published bound to loopback, so consumers dialing the
announced <node>.internal:port reach nothing. Diagnosed from the lab: DB
consumers that require the database at startup crash-loop; the provider is
healthy on loopback only.
