 ### How it works
 
-The packaged app ships only the Electron shell. On first launch it installs the Hermes Agent runtime into `HERMES_HOME` (`~/.hermes`, or `%LOCALAPPDATA%\hermes` on Windows) — the **same layout a CLI install uses**, so the two are interchangeable. The renderer (React, in `src/`) talks to a `hermes dashboard --tui` backend over the standard gateway APIs and reuses the embedded TUI rather than reimplementing chat. The install, backend-resolution, and self-update logic all live in `electron/main.cjs`.

+ * auth-mode classification, and the auth-mode coercion rules.
+ *
+ * Kept standalone (no `require('electron')`) so it can be unit-tested with
+ * `node --test` — same pattern as backend-probes.cjs / bootstrap-platform.cjs.
+ * main.cjs requires these and wires them into the electron-coupled IPC layer.
+ *
+ * Background on the two auth models a remote gateway can use:
+ *   - 'token': legacy static dashboard session token. REST uses an
+ *     `X-Hermes-Session-Token` header; WS uses `?token=`.
+ *   - 'oauth': hosted gateways gate behind an OAuth provider. REST is authed
+ *     by an HttpOnly session cookie; WS upgrades require a single-use
+ *     `?ticket=` minted at POST /api/auth/ws-ticket. The gateway advertises
+ *     this via the public `/api/status` field `auth_required: true`.
+ */

+// hermes_cli/dashboard_auth/cookies.py.
+//
+// Two cookies are in play (see that module):
+//   - hermes_session_at: the OAuth access token. Short-lived (~15 min); its
+//     Max-Age tracks the access-token TTL, so the cookie jar drops it the
+//     instant the AT expires.
+//   - hermes_session_rt: the OAuth refresh token. Long-lived (24h rotating,
+//     reuse-detected — Portal NAS #293 / hermes #37247). When the AT cookie
+//     has lapsed but the RT cookie is still present, the gateway middleware
+//     transparently rotates a fresh AT on the next authenticated request
+//     (POST /api/auth/ws-ticket), so the session is still LIVE even with no
+//     AT cookie. A liveness check that looked only at the AT cookie would

+/**
+ * Live WebSocket validation for the remote-gateway "Test remote" button.
+ *
+ * Background: the desktop boot does two independent things to a remote gateway:
+ *
+ *   1. The MAIN process hits ``GET /api/status`` over HTTP (token in a header)
+ *      to confirm the backend is up. This is what "Test remote" historically
+ *      checked, and what the boot logs print as "Remote Hermes backend is
+ *      ready".
+ *   2. The RENDERER then opens a live WebSocket to ``/api/ws`` (credential in a
+ *      query param) via ``gateway.connect()``. The chat surface only works once
+ *      THIS succeeds.
+ *
+ * Those two paths use different processes, transports, and credentials, and the
+ * server applies extra guards to the WS upgrade that the HTTP status route never
+ * sees (Host/Origin checks, ws-ticket/token auth, peer-IP checks). So a gateway
+ * can pass the HTTP status check yet reject the WebSocket — which surfaces to
+ * the user as a green "Test remote" followed by an opaque "Could not connect to
+ * Hermes gateway" on the boot overlay.
+ *
+ * This module performs the second half of the check: it actually opens the WS
+ * URL and confirms the upgrade is accepted (and isn't immediately torn down by
+ * a post-upgrade auth rejection). The ``WebSocketImpl`` is injectable so the
+ * unit tests can drive the handshake without a real socket; in production the
+ * caller passes the Node/Electron global ``WebSocket``.
+ */
+
+const DEFAULT_CONNECT_TIMEOUT_MS = 10_000

+// post-handshake closes the socket almost immediately. Wait a short grace
+// window: a frame (gateway.ready) or a still-open socket means success; an
+// early close means the upgrade was accepted but the session was refused.

+ * the `electron` binary itself.
+ *
+ * On the next run, electron-builder sees the destination directory already
+ * populated, skips re-copying the binary it thinks is present, then tries to
+ * rename a `electron` file that no longer exists. The build dies with:

+ *   ENOENT: no such file or directory, rename
+ *   '.../release/linux-unpacked/electron' -> '.../release/linux-unpacked/Hermes'
+ *
+ * This is a hard failure with no obvious cause for the user — `hermes desktop`
+ * just prints "Desktop GUI build failed" and the only fix is to manually
+ * `rm -rf` the release directory, which a normal user has no way to know.
+ *
+ * The packaging step is not idempotent across an interrupted run, so we make
+ * it idempotent ourselves: wipe the target unpacked directory up front so
+ * electron-builder always stages into a clean tree. This is safe — the
+ * directory is a pure build artifact that electron-builder fully recreates
+ * on every pack; nothing else depends on its prior contents.
+ *
+ * Cross-platform: the same partial-state trap exists on macOS
+ * (the mac-unpacked Hermes.app bundle) and Windows (win-unpacked), so we
+ * clean whatever `appOutDir` electron-builder hands us regardless of platform.
+ *
+ * Best-effort: a cleanup failure must never mask the real build. We log and
+ * resolve rather than throw — worst case electron-builder hits the original
+ * ENOENT, which is no worse than not having this hook at all.
+ *
+ * electron-builder passes a context with:
+ *   - appOutDir:            the unpacked app directory about to be staged
+ *   - electronPlatformName: 'win32' | 'darwin' | 'linux'
