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

Targeted sections only, not a full licensed specification review. No claim that every legacy, Express or multi-mode host supports another card; no fabrication approval.

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