The experiment treats the market as a repeated, adaptive decision environment. The model searches and ranks before the decision; the portfolio allocation is the action; realized return and risk are observations after the action. A higher payoff is therefore read together with the path required to obtain it.
The Adjusted Score remains an ex-antesearch signal. Calmar, Sharpe, volatility and maximum drawdown are ex-post diagnostics and are not fed back into that historical score. Keeping those layers separate avoids look-ahead leakage and makes the comparison harder to improve merely by redefining the score after seeing the outcome.
Calmar compares annualized compound growth with the worst peak-to-trough loss. Sharpe compares daily excess return with the U.S. 3-month Treasury benchmark per unit of excess-return variability. Annual volatility measures dispersion; maximum drawdown measures realized capital impairment. They answer different questions and none of them alone establishes causality.
All published risk ratios are calculated in the backend from the same governed series shown above. The public site only validates and presents those results.
