V23 400d TRUE (correct pipeline, 2026-04-21): +146.09%, DD -13.66%, Sharpe 2.33.
Prior result (+120.87%, DD -23.97%) was from buggy AH-close pipeline; data fix
improved DD by 10.31pp. V23 now strictly dominates Safe v9 on ALL 400d metrics
(+45pp return, +3.5pp DD, +0.34 Sharpe). Updated Safe v9 status to
validated_200d_only and clarified Korean framing to remove the misleading
"최종 검증 전략" without qualification.
