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

No inferred SKU, actual order availability, universal duplex polarity, connector dimensions or end-to-end reach. The filename and final-page footer differ from the repeated LAN-3921-AEN heading; the inspected revision and page locators are retained. Numerical return-loss and length-table entries are not republished.

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