Check Overlaps dismissed a tiny clamp by the part's coarse material bounds
before the fine tolerance-free test ran, but that material is inscribed at
the 0.001 chord tolerance: real material in the sliver beyond a convex arc
(a short arc cap, a rotated crescent) lay outside those bounds and the clamp
read as clear. For clamps below the tolerance the bounds are widened by the
chord tolerance before rejecting.

Circumscribing every arc holds all material along convex arcs but drops a
sliver along concave ones (a notch), so a tiny clamp 6e-7 into the material
beside a notch read as clear. Tiny-clamp checks now test the part flattened
both ways (all arcs inscribed, all arcs circumscribed): along any arc one of
the two holds the real material, so together they find every real overlap.

Fine inscribed flattening still let a native arc cut 6.2e-7 into a 1e-5
clamp unseen: less than one chord's sag, so the layout check, interactive
fill and Check Overlaps all called it clear. Tiny-clamp checks now
circumscribe perimeter arcs and inscribe cutout arcs (lines stay exact), so
the polygons hold every bit of real material. Any real overlap is reported;
the cost is a possible report within the tolerance of an arc, never a false
clear. The analyzer builds the same polygons instead of a second
OverlapMaterial read.

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.
PM 407f5eb7-329f-41e4-947e-64ad52aa4034
Collision.Check finds no overlap region for a clamp smaller than its
tolerance, so Check Overlaps reported a part covering a 1e-5 clamp as clear.
Clamps below 0.001 are judged with KeepOutOverlap and reported as a finding
whose fragment is the whole clamp rectangle; flush and clear parts stay clear.
