A roster fact used to be a name from a closed list, each formatted in Go here — node-names as a hosts file, node-zones as a resolver's zones. Every new consumer (ssh's known_hosts, an authorized_keys) meant another formatter in the control plane, in the consumer's own configuration language. Now a fact is a path and a Go template over the roster view (this node, the suffix, and every served name vs the machines). The mesh owns the data; the module owns the format. /etc/hosts is a template on the network module; dnsmasq's zones move to dnsmasq. The controller renders and reads neither. WireGuard stays a computed generator: the overlay is the substrate delivery rides on, and its config is topology, not a roster projection. Output is byte-for-byte unchanged, pinned by the hosts golden tests and the resolver tests that compose the real dnsmasq manifest.
