Rename the OpenNest.Engine.Sonnet5 scaffold to OpenNest.Engine.Opus55 and implement an independent whole-job INestingEngine (no built-in engine, registry, or best-fit internals are called or copied). - PartCatalog: snapshot perimeter -> polygon per allowed orientation, with adaptive chord tolerance and MBR-aligned rotations for Automatic parts. - NoFitCache: spacing footprints and cached Clipper2 Minkowski NFPs (convex fast path; concave sweep plus both containment terms). - FrontierPacker: per-(type, orientation) free regions (inner-fit rectangle minus NFPs), updated incrementally; gap-fill-largest, else least front advance per area^beta. - Engine: look-ahead stock choice by estimated whole-job net area, six deterministic variants, tail re-plan of the last 1-3 sheets. - Tests judged by OpenNest.Benchmark's NestValidator, including an NFP containment regression guard. P260805-10.nest (219 parts), all 9 stock sizes: 219/219 valid, 27 sheets, 91.7% utilization, ~7 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
