Fixed audit: equal and strictly past-outcome online mixtures of saved trend/linear/quadratic August-ENSO laws both had worse average CRPS, absolute/squared error, interval score and NLL than the linear component on all four station/window targets. ONLINE’s tiny CRPS gains over equal weighting came with worse interval scores on three targets. All adverse years, missing targets, numerical limits, original reviews and wording correction retained.

Process +0 — exposed revised-history research, not causal attribution, real-time validation, or a new forecast. September 30 remains the sole issued forecast. Standing three hundred forty held. Repo online-temperature-blends/README.md.
