The tolerance-free rectangle test was fed approximated material: the layout
check passed it the 1e-4-grid validation outline (a strip of real material
that wholly contains a 1e-5 clamp could vanish), and interactive fill and
the overlap check passed 0.001 inscribed arc chords (a clamp inside a disk
but outside its chords read as clear). All three now flatten the native
contours at a quarter of the clamp's smaller side, lines kept exact, so the
arc-chord sliver can never hold the clamp. Ordinary clamps are unchanged.
