A 67-drawing, 118-part job took about six minutes through the desktop Auto Nest path and was cancelled before any layout appeared. Almost all of it was the cutout pre-pass, the rest the Irregular engine. Cutout pre-pass (317 s -> 8 s on that job, same bundles and poses): - The lattice and NFP searches prepare the frame's and the occupants' validation outlines once per search (NestLayoutCheck.Prepare) instead of re-outlining and re-triangulating the frame at every candidate, and test candidates against the small occupants before the frame. Answers match the pairwise check exactly, including its leftmost-inflated rule. - A hole's proposal is replayed for the same frame, hole and offered inserts: automatic-rotation inserts ask the same question at every frame angle. Irregular engine (40 s -> 15 s, benchmark 42 s -> 19 s, same layouts): - Concave no-fit polygons are built as the union of pairwise convex sums of each footprint's convex pieces (ear clipping plus Hertel-Mehlhorn merging on the Clipper lattice) instead of n*m edge-pair quads; a footprint that cannot be decomposed keeps the old sweep. - Pair and block catalogs share one private drawing per part geometry, owned by the engine instance, so each part's best-fit search runs once per instance and across a pipeline's trial and ordinary solves.
