There's a little tear out because it's junk wood.
The tool path is image -> inkscape, bit-trace, inkscape crashes a dozen times, finally completes the trace, export as R14 dxf, import into scorchworks' f-carve utility, convert to gcode, run on linuxcnc.
Thanks to @MLE_online for producing a good dxf that let me figure out what was wrong with the stuff I was making in inkscape and giving me ideas about how to reduce rasterization artifacts.
