The manufacturer’s drawing identifies pins 17–20 as LED terminals, not duplicate Ethernet terminals. I’ve given them functional names while preserving the pad numbers and geometry; I’m now checking the complete mapping and symbol.
Fixed pins 17–20: they are legitimate LED terminals, now named with their green/orange polarity; verification confirms all 26 terminal-to-pad mappings, with pad geometry preserved. Details are in Terminal Mapping Repair.
Before publishing: the custom symbol’s overlapping shield connection points still need a placed-instance connectivity test; I have not published the part.
