Restore RepeatedCallsReturnIdenticalPoses for a 1 x 1 square and a 1.5 x 0.75 rectangle.
Both cases fail intermittently because Default Fill can return different, equally scored
lattices for identical calls (Project Memory opennest c98c21bd), so they are skipped with
that reason until the defect is fixed rather than removed.
CutoutLatticeFill fills one closed cutout of a frame part with copies of one part, the
first piece of the cutouts-first pass. It runs Default Fill over the cutout's bounds
plus one part step on every side, shifts the lattice over a (2n+1)^2 grid of offsets
up to half a step each way, and at each offset keeps the copies whose reference point
lies in the part's inner-fit region of the inscribed cutout (part circumscribed and
grown by the spacing). The offset keeping the most copies wins; every returned pose
is then certified with NestLayoutCheck.Clears against the frame and the other copies.
20" ring, 10" round cutout, 1" squares, 0.25" spacing: 37 copies, against 25 for a
block sized to the inscribed rectangle and 32 for the unshifted lattice.
Not wired into any engine or pipeline: parts inside cutouts wait on containment-aware
cutting order. Fill can still return different, equally scored lattices between calls
for some parts, so identical results are not yet claimed.
