The girdle closes the mesh but is not included in the optical facet count. The middle pavilion tier stops at Q while the inner star tier reaches the culet, retaining 20 culet spokes in the closed convex mesh.

Method note. Revision 4 is a fixed researched reconstruction. The renderer validates facet count, planarity, convexity, manifold edges, and culet spokes at startup.
