l0ng-ai 09a653d10b fix(workspace): make the CLI and the GUI agree on what exists (#423)
Five places where a workspace, a tab or an attachment was real on one side of the socket and invisible on the other. They share a root: the GUI kept its own list of which workspaces exist (WindowViews on disk) and consulted the machine tree only for the ones already in that list, so anything created by another client was unreachable by construction.

- The switcher lists workspaces the machine holds but this client has never opened, and opening one keeps its id instead of claiming a fresh one.
- for_workspace_at hydrates whenever the machine holds tabs, so opening a workspace no longer saves an empty session over them.
- finish_hydration writes a full window back over an empty tree, which is what puts a ws rm'd workspace back under the same id.
- A deletion nothing has open is forgotten here too, instead of haunting the switcher until a restart.
- Workspace::attachment travels over the wire (minus the token that proves the hold, which stays on the connection that owns it) and is stripped in persist, so tty7 ls can name the host holding a workspace.
- tab ls / ws tree fall back through name -> agent -> cwd leaf -> process name, and tab ls grew a read-only GROUP column.
- tty7 new --open raises a window on the workspace it just made.

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

Install

Native builds for each platform on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · nine themes · IME
Agent-aware per-pane detection (~18 CLIs): status dot · notifications · branch + diff · resume after reboot · tray icon when input is needed
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
CLI + Skills bundled tty7 CLI · agent skill · pane/workspace control · real PTY commands · output, process, port, and agent status
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install
