Kernel: revolved faces turned away from the angle wrap (booleans with revolved bodies work), cuts that leave pieces make separate bodies, trivial booleans (clear of / inside) by sampling, body mirrors with join; recipes: pattern source names, thread, holes at sketch points, mirror of bodies

Oracle: 43/66.
