Multicast only finds peers on the same LAN. Reach off-LAN boxes by probing them directly over unicast (works over any routable address; Tailscale is the easy, secure choice): - discovery.Probe: unicast POST /register (https->http fallback) with a two-way handshake, so send and receive both work; offline peers age out. - internal/tailscale: Peers() shells `tailscale status --json` for online peers. - config.KnownPeers: persisted manual remotes. - main.go: watchRemotes goroutine probes knownPeers ∪ tailscale peers every 10s, in both the normal TUI path and quick-send. - TUI: `+` on Devices opens an add-remote modal (host/IP/Tailscale name). - install.sh: interactive local/remote install prompt; remote mode locks port 53317 to the Tailscale interface (ufw), with container/userspace-networking detection. README documents remote devices. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
