Eren Bostan·[TAL-410]report walk-forward backtest accuracy
Backtest & Forecast Accuracy
Walk-forward backtest from 1990 to present — at every time slice the model is trained only on past data and tested on future events.
Prospective Forecast Accuracy
Every forecast is stored and verified against the USGS catalog when its window closes. Real performance — not retrospective.
