thomasandClaude Fable 5 acf6ee63d8 fix(daemon): one-shot SendInput, displaced controllers close, observers get a budget
ClientMsg::SendInput (kind 55) writes to a pane's PTY without touching the
controlling subscriber, its epoch, or the size, answered by DaemonMsg::InputAck
(kind 51) or an Error for a missing or exited pane; PaneClient::send_input
wraps it. Both stay within protocol 5.

run_stream now polls its half of the socket and epoch-checks against the pane
before forwarding Input or Resize, so a controller displaced by a preempting
Attach stops writing into the shell and has its connection shut down instead of
half-open forwarding forever.

Each observer meters its queued Output through its own OutputGate; one that
lets 8 MiB pile up is pruned rather than growing daemon memory, while the
controller and the PTY never wait on it.

The pidfile reap guard accepts any legitimate daemon exe name (current exe,
tty7-app, tty7-server, tty7; .exe optional, case-insensitive on Windows), and
the agent-hooks console fast path matches tty7-server.exe and tty7.exe next to
tty7-app.exe.

Why

  • Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Sessions persist — quit or reboot; your shells keep running, no tmux
  • Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
  • Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume

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 libs bundled

What's inside

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
Coding agents per-pane agent detection (~17 CLIs): status dot, notifications, branch + diff, resume after reboot, tray icon that signals "needs your input"
SSH native russh stack: profiles with keychain secrets, SFTP panel, port forwarding, jump hosts

Details for every row: docs/features.md. Keybindings: ⌘ , opens Settings — browse and remap everything, tmux preset included (full list).
