Claims [4]+[5]: head-to-head exact-LP P1 vs entropic P2+P3 scaling (near-linear vs superlinear, in-band speedups, <10% gap) and shadow-pruning degradation curve (60-80% edge reduction, <10% degradation); full source shown

Reproduce MAPF-OT theory: P1 LP -> integral min-cost-flow optimum (Lemma 3.3), constraint matrix TU (200k submatrices, max det 0) via node-arc incidence
