Provide a separately installed OR-Tools model to compare a generic constraint solver with the native first-solution path without adding a production or default-test dependency. Use no-overlap, exact-fill, edge and equal-copy symmetry constraints, validate placements independently, and record model size, memory, worker count and timings for orders 8 and 9. Keep the tool only as a reference and defer DLX absent new evidence. Tests: Release CTest (9 passed) Tests: Python reference tests and compilation checks Tests: independently validated CP-SAT orders 8 and 9 Refs: #5
