Corrects the day-ahead information protocol, replaces the weak hourly-mean forecast with SARX, expands price-state selection to K=48 with hierarchical smoothing, adds nonlinear DOD/SOC aging, publishes 30-seed and DK1/DK2 block-schedule results, and adds 13 verification tests. The corrected evidence shows SARX MPC outperforming the hour-aware MDP, while the hour-aware state outperforms the matched price-only MDP.
