#462 visited nodes by a mirror-invariant key (distance from the centroid). On the cup with a handle that order sweeps ring by ring round the axis and converges worse in its 100 sweeps: the refined cup fell to a scaled Jacobian of 0.481 (needs 0.5, #440). In the lattice's own order it holds, and the order gained the enclosure base little (its corners differ by 0.02 either way), so it goes; the compass search's lift to 0.7 stays.
