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

Counts are scoped to named modes. The overview does not identify an exact card or host, and extra-row count does not establish implemented protocol.

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