Some Windows shell brokers enforce `ProcessRedirectionTrustPolicy` on what they launch. The daemon inherited it, every ConPTY shell under the daemon inherited it in turn, and PowerShell could then no longer traverse a user-created junction — which is exactly what Scoop's `current` links are. `oh-my-posh` and `fzf` died with `Shim: Could not determine if target is a GUI app`. Windows Terminal was unaffected because its process tree never picked the policy up. The policy cannot be relaxed once enabled, so the fix is to not inherit it: when tty7 detects the enforcing bit, it creates the daemon with `STARTUPINFOEXW` and `PROC_THREAD_ATTRIBUTE_PARENT_PROCESS` naming the interactive desktop shell, which supplies the ordinary desktop token, device map, and mitigation policy. The Win32 code stays isolated in `daemon/spawn/windows.rs`, and the ordinary path still runs whenever the policy is absent — or whenever the desktop shell cannot be borrowed, in which case tty7 logs a warning and starts degraded rather than not at all. Because naming a logical parent makes handle inheritance follow that process, the daemon starts with no standard handles. `daemon::server` and the pane reader's trace line now write to stderr in a way that tolerates that, instead of `eprintln!`, which panics on a failed write. ConPTY exit ordering: the process-exit monitor could observe a short-lived shell exiting before the reader had delivered its final frame, so `Exited` reached clients ahead of the output that preceded it. The monitor now releases the pseudoconsole and lets the reader — which reports only after forwarding everything up to EOF — announce the death, with a bounded window behind it for the case where EOF never arrives because a grandchild holds the ConPTY output pipe open. Note this changes the daemon's token on the clean-parent path: it derives from Explorer, so an elevated tty7 starts a medium-integrity daemon.

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
- 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
