l0ng-ai a1440f34f8 fix(daemon): stop offering to carry on beside a mismatched server
Both handshakes compare their version for equality and hang up on
anything else — the pane protocol in `ensure_running`, the control
dialect in `host::server`'s hello. So a server whose number disagrees
cannot be talked round, and the "Keep Shells" button offered a state
that does not work: panes still spawn while every machine-tree call is
refused, which is how a window opens with no tabs and saves none of the
ones you make. Taking that button was indistinguishable from the bug it
sat next to.

Restart or quit, then. Quitting is the half that destroys nothing — the
server and every shell under it keep running — which makes it a real
answer for someone who would rather go install the matching build than
lose a session mid-flight. Quit goes first, the way every other
destructive prompt here is ordered: NSAlert and TaskDialog give the
first button Return, and this prompt arrives unasked at launch, the
moment a stray Return is likeliest, so the reflex key has to be the one
that destroys nothing. Restarting stays a click or an arrow away.

A prompt dismissed without an answer re-arms instead of falling through:
`take_mismatched_daemon` takes, so without this a closed window is a
back door into the state this prompt exists to prevent.

The copy is rewritten to one line of diagnosis and one line per button,
in all three locales, listed in button order. It was a paragraph that
had to be read twice to find out what the buttons did.

Why

  • 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
  • Editor-grade input — suggestions, completion, highlighting, history search
  • Remote development — files, repos, panes, and git data stay on the remote machine
  • Native SSH — profiles, SFTP, port forwarding, and jump hosts
  • Agent-aware — Claude Code, Codex & co.: status, notifications, git context
  • CLI + Skills — agents create panes, run commands, and inspect output

Install

Native builds for each platform on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · nine themes · IME
Agent-aware per-pane detection (~17 CLIs): status dot · notifications · branch + diff · resume after reboot · tray icon when input is needed
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
CLI + Skills bundled tty7 CLI · agent skill · pane/workspace control · real PTY commands · output, process, port, and agent status
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install

Terminal and keybinding reference: docs/features.md. The agent-facing CLI interface is documented in skills/tty7/SKILL.md.
