Precommitted 50/50 chronological split (rank first half by return/maxDD, require second half positive and a neighbour parameter to agree) on price>EMA, dual SMA, Donchian. Replaying with indicator_lookback_v2 (second half keeps first-half indicator history) removed the apparent EMA 220-240 edge (second half -0.4% to -6.4%); positive cells were isolated spikes (EMA160, EMA300, Donchian20), not plateaus. Abstains rather than label a spike.",
