Five two-year walk-forward folds (2014-2024), each with its own pre-fold parameter fit; selection by mean fold RPS; staged greedy over Team-DC decay/shrinkage/weight, fast-Elo blend, form multiplier, and new Elo-walk axes (home advantage, K scale); untouched 2024-26 final test. Result: the shipped v4 config holds — the staged champion gained 0.0003, under the 0.0005 ship bar, and the final test agrees. v4 is no longer a one-window result.
