`y` in `traffic_light_position()` is the gap between the window's top edge and the top of the button frame, and AppKit draws those buttons 14 points tall, so the lights' centre lands seven points below it. The tiles beside them are centred in the title bar's content box instead — `TITLE_BAR_HEIGHT` less the hairline `TitleBar` draws along its bottom edge — which is 23.5 in a 48pt bar. The constant was still 17, the value the 40-point bar needed (13) rewritten by hand when the bar grew to 48, without that border in it, so the lights' centre came out at 24: half a point low, one whole device pixel on a Retina panel. It comes from the bar's own height now — `(48 - 1 - 14) / 2 = 16.5` today — and a test holds the lights to the tile line, so the next change of bar height has somewhere to move with it. Measured on macOS 26.3 with the style mask gpui uses (`fullSizeContentView` and a transparent title bar): the standard buttons are 14×14 points with 9 points of padding, in a 32pt title bar.

tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty

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 the app and your shells keep running; after a reboot, layout, screen, and supported agent conversations come back. 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. Past sessions are read from the agent's
own history files and listed in Search Everywhere, where ⏎ resumes one.

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, and the New Tab menu names the ones you have actually
run. agent_launch sets the command line it starts with.
