Validation

What happened after the signals

Real outcomes of daily snapshots: buy at the next session's open, sell at the horizon's close, 5+5 bps costs per side. Grouped by score band and model version, because different versions are not the same measurement.

A live record that grows over time, not a backtest: the universe is Krazerr's coverage (momentum-selected, no delisted names), samples are small and overlapping, and no weight is optimized on these numbers. Price returns without dividends, not portfolio returns.
