- RecRoomPicker.Detect: scan common manual-install paths (Documents/Recnet/dist, Downloads, C:\Games, etc.) on first run; never touches Steam libraries per policy - RecRoomVersionDetector: three-signal cascade (version.txt -> PE timestamp -> file size) maps install to a manifest branch so version dropdown defaults correctly - CloudflaredInstaller: download latest cloudflared-windows-amd64.exe from GitHub releases to %LOCALAPPDATA%\DorkNet on first host; resolves side-by-side -> cache -> PATH -> download - LocalNetwork.GetLanIp + AppState.HostingMode (Internet|LocalNetwork) + Host view "WHO CAN JOIN?" radio: LAN-only mode skips Cloudflare entirely for families on one network - OnHostStart branches on HostingMode; status text reflects local IP vs public tunnel URL
