On a board with an aux origin, kicad-cli writes the IPC-D-356 netlist relative to that origin while Gerbers and drill files are absolute, giving 130 dfm_net_open errors and a shipped .ipc that would fail the fab electrical test. The same report found the DFM check splitting KiCad RoundRect pads into pieces, producing false 0.114 mm ring findings on pads whose real ring is 0.33 mm.
