Every sidebar row carries its tab's `+N −M`, and the counts are their own click target. They read the git path off `self.tabs[i]` — the row — and then called `toggle_diff_overlay`, which writes to `self.active`. The two are only the same tab when the row clicked is the one already in front. Clicking another row's counts therefore opened *that* row's repository as an overlay on the tab already in front: focus never moved, the front tab showed a diff from a directory it has nothing to do with, and the overlay stayed filed under the front tab afterwards, so every later read of "the active tab's overlay" kept returning it. The row's tab now comes forward first, and the overlay lands on it. Arriving from another tab opens rather than toggles. `open_diff_overlay` is itself the toggle — the close lives there, not in its `toggle_*` wrapper — so activating the target first was not enough on its own: a target that already had that diff open and in front answered a request to show it by closing it, leaving the screen on nothing that was asked for. `may_close` is what separates the two, and only a click on the tab already in front sets it. The bounds check is the same bug by another route: `activate` no-ops on an index it does not have, which would leave the open writing to whatever tab happened to be in front, and a row can outlive its tab between render and click. All three tests were run against the unfixed code, not only a green tree; two of them fail there.
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 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

| Git | panel follows the focused pane · stage, commit, amend, branch, push, stash · side-by-side or unified diffs · commit graph with cherry-pick, revert, and reset · a new worktree opens its own tab |
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.
