The two webviews (local title bar, remote web UI) become one WebviewWindow on ui/index.html. The window refuses every navigation but the app's page and its sealed frames; the capability still names only main and no remote URL. - server.rs: discovery refuses a server older than 2.0 (protocol 3 and major version 2) and an app API newer than this app knows; the app's own device login for the app scope, the token kept in account.json (0600) and never given to the page; a proxy limited to /api/v2 paths; the SSE stream. - files.rs: list and read the agent's working directory, resolved (links and .. included) and refused outside the agent's folders. - sealed.rs: HTML for the viewer on its own scheme under the server's sealed policy: no bridge, no network, no navigation. - watch.rs + tauri-plugin-notification: a notification when a reply or an agent chat finishes out of sight. - A failed start and panics go to desktop.log; a missing tray no longer stops the app; the DMA-BUF renderer is off under NVIDIA's driver. - The unstable multiwebview feature, the gtk dependency and the theme report are gone.
