From the llvm-cov run of `difftest --green`: 136 fixture cases (fixtures/<unit>/coverage.json, each citing the upstream branch and the Rust line it covers) execute about 70 previously uncovered spans in offset_surface (zero first derivatives replaced by base tangents, a hyperboloid base), sphere (coincident/concentric spheres, degenerate arcs, tangency marks, cone and box rejects, pole and seam inversion), surface_p5 (singular iso curve, CoverOtherCoincidentSurface branches, IdenticalSolutions at a pole), surface_p4 (curve/surface crossing classification on dome, saddle and cylinder points), surf_of_extrusion_p1 (coincident generators touching or disjoint), surface_p6 (solutions at a pole), surface_point_solve_p2 (cross-seam solutions), torus (horn torus, axis-start minor circle), curve_bounded_surface (== stops) and surf_of_revolution_p1/p3 (revolutions of a real SmHyperbola). The surf_of_revolution_p1 runner, FFI and shim gain a hyperbola generator; the five shims sharing that generator block parse it too. Fuzzing it showed SmHyperbola's constructor ignoring a failed MakeNurb (NULL or non-finite NURB, then a segfault): the shims refuse such a hyperbola, and plan/upstream-issues.md UB-46 records the trigger. Generated cases are unchanged. All eleven units PASS with 0 failures and 0 deferred (max_rel_err 0); --perturb SENSITIVE on all; --fuzz 200 (p1, p3, offset): FUZZ-PASS.
