The hysteresis params were chosen by looking at the data = in-sample. Clean OOS protocol (same
that killed PEAD): pick best config on first 60% by IS Sharpe, apply EXACT config blind to last
40%. Reports IS-best -> OOS Sharpe, robustness (configs IS>2 that also OOS>1), OOS per-month.
Decisive: OOS holds -> real; OOS collapses -> in-sample fit. Monitor armed.
