tab new --pane (#716)
A pane can come out from under its tab with its shell still running — an interrupted `tty7 run`, a `ws rm` that could not hang everything up, or a client that closed nineteen tabs whose shells were all alive (#716). `pane ls --all` has been able to *show* those for a while, but everything the CLI offered to do about one was to kill it: `pane close %<id>`, or `pane close --orphans` for the lot. The shells were fine. There was simply no verb that put one back on screen, so recovering meant recreating tabs by hand and reaping the originals. `tab new` grows a `--pane` that builds the tab around a pane that is already running instead of spawning a shell for it. Nothing new had to be invented on the wire: `ControlRequest::TabCreate` has always taken a `PaneSeed` with a pane id in it, which is how `run --keep` files its pane into a tab. The part that needed designing is where the seed comes from. `tab_close` retains the orphaned panes out of `m.panes` at the same moment it drops the tab, so by the time anyone wants a pane back the tree has already forgotten its record — cwd, title, shell. Reading the seed off the tree would therefore work for an interrupted `run` and fail for exactly the case this verb exists for. It is rebuilt from the live pane registry instead, which still has the pane because the pane is still running, and which is the same list `pane ls --all` walks. That does mean `ssh_spec`, `agent` and `shell` are not recovered — the registry never carried them. They cost nothing while the shell lives, since the tab is a view onto a pty that is already there, and only matter if the pane later dies and something tries to restore it from the seed. Reconstructing them from a running pty is a different problem; a tab you can see beats a shell nobody can reach. Two refusals rather than one guess: a pane the server is not running cannot be re-homed, and neither can one a tab already holds — that is what `pane split` is for, and accepting it would put a single pane in two places in the tree. With no workspace named the pane goes back to the one it was spawned for, which is the `owner` that `pane ls --all` already prints; `$TTY7_WS` cannot help here, because a shell recovering from this is by definition not inside tty7. The `pane ls --all` footer now names the way back as well as the two ways to kill, since the listing is where an orphan is found and so is where the recovery has to be written down. Deliberately not done here: the switcher's orphan rows still carry only a Close button. Adopting from the GUI is not the same one-line change — the row lists orphans machine-wide while a window speaks for one workspace, and a pane may only be attached by the workspace that owns it, so the button has to decide where the tab goes before it can build one. That is its own piece of work. Claude-Session: https://claude.ai/code/session_01UUyWQXzcBAoBzaSX8pc7nU
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
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
- Git beside the terminal — source control, diffs, and worktrees without leaving the window

Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Agents 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.
