The desktop launcher opens the T&R road and enters the Super sign. Super's existing trusted webview is placed inside the sign's read frame. It is not a screenshot, a second runtime, or a button that opens a separate cockpit window.
Use Leave window to return to the road. Select the Super (CD) sign to resume the same live view and session. Resizing keeps the view aligned with the sign. Closing the road exits the desktop application.
The road webview remains cd-road; the trusted app view remains main. The road has only a narrow super_sign placement command and cannot submit runtime intents, choose files, or operate bots. Browser previews and terminal views remain separate webviews with their existing permissions. Linux placement uses a native overlay with explicit child allocations.
The product adapter is in cockpit/road-host/adapter.js, applied to shared road assets by cockpit/build.rs. Notes and Digest remain standalone proof apps in RRABBIT; Super's product catalogue presents Super. SUPER_ROAD=0 is an explicit troubleshooting/test override for the desktop launcher.
Run tools/native-ui-test.sh node tools/super-sign-smoke.mjs with native test dependencies available. It measures the live viewport against the sign, checks runtime connectivity, denies an intent from the road, verifies leave/re-entry without recreating the session, and verifies resizing. tools/road-battery.mjs uses this product flow; RRABBIT retains its standalone proof tests.
The Linux launcher defaults to X11/XWayland with WebKit compositing disabled, matching native integration testing. Native Wayland showed duplicated road pixels in the reparented Super view on the target desktop. SUPER_DESKTOP_BACKEND remains an explicit troubleshooting override.
