The authors introduce TRIP and GRIP, tasks that certify the graph-information range required for prediction. On ECHO topologies, classical baselines reach MSE 1.0 by range 4 on TRIP tasks, while PHDGN and SWAN remain meaningful learners; the corresponding gap is absent on original ECHO tasks. This comparison tests long-range modeling, but does not identify why rankings differ or establish a universally effective architecture.
