Test matrix
What to test and what a pass actually tells you
Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.
Use the result to narrow the next branch; browser visibility is intentionally limited to the subsystem exposed by the current API.

Evidence handoff
If the browser cannot reach the suspected subsystem
Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
