This registration tests the spherical case, which is the one with a numerical signature (equal radii in perpendicular sections) that a published table can carry. A sphere has non-zero mean curvature, so it is not a minimal surface in the strict sense (H = 0); that distinction is not given a second verdict here, because no mean-curvature table was part of the registered observable.
