Field notes
The test catalog distinguishes observation from diagnosis: it says a browser sees only events exposed by the operating system, and that settings, connection, focus, and browser behavior can affect results. Some checks expose user-adjustable conditions, including a threshold for highlighting close clicks and a chosen duration for a stick-at-rest observation. A vibration check is conditional on the browser and controller providing an actuator.
