At each step compute exact selected-line occupancies and marginal triple penalties, solve a fresh integer min-cost b-matching with row/column supplies and all eligible cells, and perturb costs for escape/restarts. Measure exact triple energy after each matching and independently checker-audit any zero. Freeze best coordinates, seeds and trajectory.
