internal/discovery registers three service types on the listen port: _vellum._tcp for native clients, and _jellyfin._tcp / _subsonic._tcp because those ecosystems already have clients that browse the LAN. That last part is the point: Infuse, Jellyfin Media Player and Symfonium can find Vellum with no client-side work, because they are already looking for those names. TXT records carry api, ver, proto, types, tls and (when set) pub, so a client that resolves one can tell what it found before connecting. Definitions is a pure function of config and Start only registers what it returns, so what is advertised is testable without a socket. Two behaviours worth knowing: - VELLUM_DISCOVERY=off stops advertising. It accepts off/no/false/0; strconv.ParseBool would have silently ignored "off". - A loopback-only listen address advertises nothing. That is the normal shape behind a reverse proxy, and advertising it would put a port in the LAN browse list that refuses every client that dials it. Verified red-green: defeating the guard fails TestDefinitionsSkipsLoopbackListen. zeroconf is the only new dependency. It logs to the stdlib logger, so a host with no multicast-capable interface prints to stderr outside slog. Not verified: real mDNS on a real LAN. There is no multicast here, so the wire behaviour of zeroconf is untested - only the definitions it is handed.
