The benchmark is about to be used as the objective for LLM-designed engines, and several gaps would have rewarded the wrong behavior: - Ranking was utilization-first, so dropping awkward parts raised the score. Rank valid > fully placed > cost > plates, where cost is salvage-credited sheet area plus a largest-sheet penalty per unplaced part; placing a part is never scored worse than omitting it. - Salvage rate was ignored in scoring; cost now uses EstimateNetArea, recomputed from job geometry rather than trusted from the engine. - Rotation constraints were never validated. Add RotationPolicy.Allows (shared with NestJobPlacementValidator) and check every placement. - Returned sheets were trusted, so an engine could loosen spacing or invent a size. Sheets must now match offered stock. - Part-in-part placements were flagged as overlaps; spacing now accounts for cutouts, with an X-sorted sweep to prune distant pairs. - Summary averaged per-job percentages; it now sums areas and cost. - --spacing and sheet sizes parsed with the current culture. - Warn when .nest jobs offer only their original sheet sizes.
