Kernel rig: everyday rounds of a pocket and a boss
A rectangular pocket's floor edges, rim edges and both rounded r2, the rim r5 as deep as the pocket; a boss's root r2 and r10 (as tall as the boss) and its top rim r2. The rim cases fail today: SMLib puts a corner patch where two rim rounds meet at a concave pocket corner, where the rounds running into each other make a mitre (four faces more; the volumes agree to 5e-4).
