Kernel: concave edge fillets; whole smooth-loop blends of planar faces (cylinders and tori: pocket floors, plate outlines); rounding every edge of a convex planar body (sphere corners); healing after booleans (exact lines/arcs for intersection curves, coplanar faces merged, collinear edges joined); faces rebuilt on their stored surfaces

Oracle: 28/29.
