Recorded AI-assisted source inspection; not independent human approval or hardware testing.

Apple chip limits still apply. This is not evidence that every later firmware, OS or exact monitor pair was tested. Charging is outside this extension.

Source inspection is separate from independent technical approval, rights clearance and hardware testing.
