Field notes
The tester's visible workflow begins with connecting a gamepad and pressing a button, which browsers may require before exposing controller inputs. Its diagnostics include raw axes and button readings alongside stick tests; the page says the three-second hold estimates resting offset and noise. A calibration wizard is described as building a correction profile without writing to the controller, but the extracted homepage does not demonstrate that workflow with a connected device.
