The desktop shell pinned USE_TMUX=0 on every platform, not just Windows. Without
tmux the shell is a direct child of the embedded server, so SessionManager.shutdown
takes the kill branch and quitting the app — the tray Quit, a logout, an update —
ends every session with it.
That defeats the app's premise. The point is to hand Claude Code a task, walk away,
and reconnect from another device; a session that cannot survive the window closing
does not do that. With tmux the node-pty process is only a tmux CLIENT, so shutdown
detaches and the shell keeps running, which is exactly what the standalone server
has always done (USE_TMUX unset → 'auto' → is the binary present?).
Non-Windows now defaults to 'auto'. Windows stays forced off — tmux is a *nix
keepalive. An explicit ambient USE_TMUX still wins either way, so USE_TMUX=0 remains
the opt-out.
Tests assert the end-to-end result, not just the emitted string: buildServerEnv fed
through loadConfig yields useTmux === true with tmux installed, and false for an
explicit opt-out. The original bug was these two layers disagreeing about what a
value meant, so checking the string alone would not have caught it.
Sessions started in the app before this change are NOT retroactively protected —
they have no tmux session behind them and will still die with the app. Only sessions
created after the new build is installed survive.
When the always-on tunnel daemon already serves :3000, the app reuses it
(close() is a no-op) rather than spawning a second server on another port, so
the GUI and the tunnel share one base app.
Add a `desktop/` Electron app that embeds the existing Node server + node-pty
(all-in-one): the window loads http://127.0.0.1:<port>/ and reuses the frontend
unchanged; other LAN devices can still connect. The server needs zero changes —
startServer(cfg)/loadConfig already support programmatic embedding.
- Pure, unit-tested modules: port, shell, server-config, deep-link, notify-policy,
notifications, live-poll, prefs, settings-store (94 tests; desktop/src ~97% cov)
- Electron glue: main/window/tray/menu/preload/embedded-server/logger
(hardened: contextIsolation, sandbox, deny foreign-origin navigation)
- Native value: OS notifications driven by /live-sessions status, tray, deep links
- Packaging (electron-builder -> arm64 .dmg): ships dist/ + public/ + node_modules
on-disk under Resources so the server resolves its deps from /Applications;
node-pty rebuilt for the Electron ABI
- Docs: docs/DESKTOP_PLAN.md; PROGRESS_LOG updated
Verified: desktop tsc clean; 1401 tests pass; coverage >=80% (desktop/src 97/95/100/97);
.dmg built and launch-tested on arm64 (server boots, UI serves 200, node-pty loads).
