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 -> 0 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.
footprint: the datasheet shows TO220-5L - 5 leads at 1.71mm pitch, matching the symbol's 5 pins - on a 3-pad TO-220-3 footprint. Chosen from this part's OWN datasheet, not inferred from a sibling - the Richtek SOP-8-EP parts alone carry three different exposed-pad sizes, so family inference would have been wrong. Rebuilds the .lbr, re-derives pin 1 and pads.json.
