`push`, `pull` and `fetch` run for as long as the network takes. A remote host sent them as a plain `Git` request, whose client-side deadline is the 20 seconds an interactive query gets, so anything slower came back as a timeout while the far side was still working. Add `Host::git_with_deadline`, a provided method that names the ceiling at the call site. `RemoteHost` sends the same `Git` request it always did and only widens its own patience, so the bytes on the wire are unchanged and a server that predates this serves it as-is: no new verb, no version bump. `LocalHost` does not override it — `Command::output()` has no timeout of its own, so forwarding to `git` already means "wait until git is done". Waiting longer is only useful if the thing we wait for cannot stop to ask a question. Give every git `LocalHost` spawns an environment that forbids prompting: nulled stdin was not enough, because without `GIT_TERMINAL_PROMPT` git opens `/dev/tty` itself. The read path carries the same environment rather than a separate one — `status` and `diff` have nothing to prompt about, and the wire has no bit that says "this request talks to a network", so the remote server has to reach the same rule from the same args to be protected at all. Guard the byte fidelity the SCM panel now leans on: `-z` output keeps its NULs through `Host::git` (`git_lines` would rejoin the records with newlines), and a `:(literal)` pathspec reaches git unrewritten.
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty

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
