Both HasOverlappingParts loops rebuilt each part's polygon from its Program on every pair. PartOverlapChecker prepares each distinct Program (reference identity) once and each part's world polygon once per call, then uses the overlap-only Collision.HasOverlap. Loop order, bounding-box prefilter, early exit and returned indices are unchanged; Part.Intersects shares the material/polygon recipe and still returns crossing points. Verification: - Frozen LegacyPartOverlap differential (original Intersects and both loops): verdicts, indices and world polygons bit-identical across fill grids, patterns, touching/epsilon gaps, scribe/rapid/empty programs. - Debug OverlapPolygonPreparations: 246 -> 1 and 64 -> 2 per check. - Corpus job (169 parts, --engines Default --parallel 1, with 1a): median 18,885 -> 13,464 ms over 4+4 alternating runs, identical outcomes; serialized layout byte-identical to the base.
