The thickness criterion read each boundary triangle's wall once, at its centre. A planar face is a few large triangles, so a face beside a pocket reported the wall its centres face (60 mm through the stepped block) while the wall beside the pocket was 5 mm: the cells there stayed coarse, the core in the wall was notched, and its padding was dragged across the pocket and crushed (4 uncertified elements, then the retry cap). On a triangle larger than the cell the wall is now also measured where the triangle is nearest the cell, held to the thinnest wall the plan chose the levels for. stepped-block now meshes; the other corpus parts keep their meshes.
