 {"reason":"the 2D route sews a cut whose outline has a point a hair from a segment's end (text-recut): seed 53's shell (step 3, a 2 mm shell of an extruded L with an arc side, opened at the notch's inner face) builds its cavity by the 2D route in 77 ms, where it took the B-rep path (2.4 s) and gave a part 336 mm³ lighter, which a box can't then be intersected with (no result). Its section at mid height is 338.27 mm² (a distance-rule raster of the profile gives 343.7, rounding the cavity's concave corners); the generator then builds the step 4 fillet it refused before, so the run goes on another way (16954.55 mm³, 48 faces)","seeds":[53]},
   {"reason":"#726 (#1687): a full revolve of a profile off the axis comes out with its planar faces whole, so the revolved section has fewer faces and edges.

Seed 9 now ends ok instead of failing, but its new design ends the same on main. No seed gains a failure.","seeds":[9,10,13,15,17,19,22,24,25,26,30,63,75,76,78,90,91]}
