Sharper measurement, clearer answers.

• Stick drift no longer reports a failure from one stray touch — the resting pass needs a real run of samples before it judges.
• A test that could not measure now says so and offers a retry, instead of printing a verdict about your controller.
• The rim sweep shows rings for the arcs you have covered, so you can see what is left.
• Input is read at the controller's own rate rather than the screen's, so fast presses and quick flicks are no longer missed.
• A controller on a cable no longer leaves the checklist unfinishable, and devices that are not full gamepads are named honestly.
