Rig: blends that end where their face runs tangent into another
Fifteen fillet cases on the test-peg's shape with clean numbers: a bar 40 x 16 x 10 whose far end is a half disc R8, a disc R8 standing 10 on its top, joined, so the front face runs tangent into the cylinder along x = 40 and the front top edge (convex) meets the concave arc of the top tangentially there. Each blend ends on a face tangent to the one it rolls on. - Rounds: both edges together at r2 and r5; one after the other in either order at r2, and at r1.5 and r3; the front edge alone as a curvature round, whose end on the cylinder is a semicubical cusp. The containment invariant (the unblended body's exact box, to 4e-5) and G1 seams, or the analytic volume where the blend has a closed section. - Chamfers: the front edge alone and the concave arc alone (analytic volumes: the section along x up to the wall, the cone's spandrel ring clipped by the sides), both together, and one after the other (1 then 2). - STEP: the peg written to STEP and read back, its front edge rounded (analytic) and both edges rounded together. - A cone: the peg drafted 5 deg, whose front face runs tangent into a cone along a generator, its front edge alone and both edges together. The quadratures are tanh-sinh, converged to 1e-13; SMLib's own volumes of the passing analytic cases agree to 4e-9. A sphere is left out: a plane meets a sphere tangentially at a point, not along a seam, so it is not this ending. On SMLib 2fc375f eight fail, listed in KNOWN_FAILING: every chamfer that ends tangent (status 1001, SmFilletNx1Corner), the two rounds together (the corner patch 0.0374 at r2 and 0.128 at r5 out of the front face, and the rounds meeting with normals 180 degrees apart where their contact lines on the top cross), the same on the STEP-read peg (status 1001) and on the drafted peg (its corner refused as unsupported).
