Not a dumpster fire:
Inside-only roughing without “clear voids” does this:
In this rough/outline scheme, the void cutout seems more like an outline thing.
I can’t cut that slot without making it a “wide cutout” - which makes it more like an outline op.
Using “clear voids” works for this part but would hurt more for larger voids.
Maybe uncleared voids are “outside” the part in the domain of outline ops? - which would make “outside” discontinuous. Maybe they are a different kind of “outside”. Questions that will evaporate in 2.5/6 refactoring, I suppose.
