-The Runtime API ships a same-origin operator console at `/ui/`, rendered through
-Jinja2 templates packaged with `device-agent-runtime`. Start the API
-(`uvicorn api.rest:create_app --factory`) and open `/` (it redirects to `/ui/`).
-The `/console/*` JSON endpoints remain available for programmatic clients. The
-console assumes a trusted local network; it has no authentication, authorization,
-or CSRF protection.
+Runtime is an in-process execution library, not a standalone HTTP service. The
+Host Agent console at `http://127.0.0.1:8765/tasks` is the authenticated
+operator view for the tasks that actually execute on that Host, including
+per-step screenshots, OCR observations, and UI-tree results. The Cloud Console
+remains the fleet-level view for dispatch status and Cloud-proxy planner history.
