Every `serve` bound a random port, so a restart left each phone holding addresses that no longer answered. Where the n0 relays are unreachable, which is common behind the Great Firewall, the phone had no other way to find the gateway until it was paired again. - `serve` listens on the same UDP port every time. It picks one on first run, keeps it in `<config dir>/mobile/port`, and moves only if the port is taken. IPv6 binding may fail, as in iroh's own defaults. - Both ends add mDNS lookup (`iroh-mdns-address-lookup`, service `_tty7._udp`). On the same network a phone finds the gateway by key when its addresses are stale, such as after a new DHCP lease or a new IPv6 prefix. The gateway advertises and the phone only listens. If multicast is refused, each side starts without it and says so, rather than failing. - iOS: `Info.ios.plist` declares the local-network use and the Bonjour service, without which iOS blocks multicast. - An ignored test (`--test mdns`) connects by key alone over mDNS, for a machine that allows multicast.
tty7
A terminal workbench: persistent sessions, remote work, agents.

Why
A background server owns your shells and panes — not the window. Everything below follows from that.
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
- Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
- Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
- Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack

Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Integrations to install that agent's hook,
and brings the status dot, notifications, the tray icon, tty7 wait, and resume
after a reboot. Fork needs both — the agent's own fork command, and the hook
that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get,
in a normal PTY, with its own interface. An agent launched through a wrapper
script can be mapped to one by name with agent_commands in config.json.
Every agent on your PATH is also a row in Search Everywhere (Agent: Claude Code, …)
that opens it in a new tab; agent_launch sets the command line it starts with.
