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

No normative test procedure, benchmark, logo asset or copied class table. No certification lookup performed for a user card; camera mode and exact product still require checking.

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