 random-sign beta, centered EP, and one SDIL arm.  S0 is development evidence
 and is never reported as a final result.
 
+S0 did not select a magnitude. Clean PEP reached 57.55% holdout accuracy,
+while raw offsets from 0.003 through 0.1 reached 60.0--61.8%. At this short
+horizon the fixed offsets were not harmful. Random-sign and centered raw arms
+were lower at 50.9% and 53.45%, but their clean controls were absent, so this
+does not isolate an offset effect. SDIL reduced the residual update offset to
+`1.30e-9` of the clean update. A larger-range S0b screen is required.
