ryucad (Seiraiyu)MCADConfidence: Medium

A STEP import campaign over KiCad 9.0.9's 3D model library refused 230 models because bent pins and leads are built on horn tori, which the kernel calls degenerate even though no face uses the bad region: 95 D-sub connectors, 49 axial resistors and 34 DC-DC converters among them. The campaign PR records 2,642 ledger lines for KiCad's models and files issues #311 to #326, one per root cause.
