rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged.
orderable attributes: rebuild .lbr with adom-lbr 2.18.0 so MPN, MANUFACTURER and the distributor part numbers reach <technology> (LCSC_PN C255474). The published library carried no attributes at all, so a BOM had nothing to buy from. Distributor PNs matched on exact MPN AND corroborating manufacturer.
