+    V23 Safe v9 — v8 + streak_sizing_win_bonus: 0.70 (V23 level streak sizing).
+    VALIDATED champion of the Safe family on 200d window ONLY (2026-04-21).
+    주의: 400d에서는 V23이 모든 지표에서 완전히 우월 — +146% vs +101%, DD -13.7% vs -17.2%.
+    v9는 200d 단기 보수적 대안으로만 유효. 실전 배포 기준은 V23.
+
+    Safe v8 결과: +82.36%, DD -7.72%, Sharpe 3.14 — V23 Sharpe(3.01)보다 높고 DD는 5pp 낮음.
+    단, 수익은 V23(+109.32%)보다 27pp 낮음. 차이 원인: V23의 streak sizing(win_bonus=0.70).
+    V23에서 streak_sizing은 핵심 수익 증폭기 (V19→V21 승진에 기여).
+
+    v9 가설: v8 safe mechanisms(partial_exit + rolling_loss-2% + max_sim=2) + V23의
+    streak_sizing(0.70) = +100%+ 수익 AND DD < V23 -12.91%?
+
+    200d 결과 (2025-07-03→2026-04-20): +101.25%, DD -7.62%, WR 58.06%, Sharpe 3.34
+      worst_day -$324, trade_days 46/200, 124 trades.
+    400d 결과 (2024-09-13→2026-04-20): +101.01%, DD -17.20%, WR 57.08%, Sharpe 1.99
+      profit_factor 1.77, worst_day -6.11%, 226 trades, 93 trade days.
+    400d gate: DD -17.20% ≤ -18% ✓ AND return +101% ≥ +90% ✓ → PROMOTED.
+    V23 대비 (200d): DD -5.29pp 개선 (-7.62% vs -12.91%); Sharpe +0.33 우위;
+    수익은 -8pp 낮음 (-101.25% vs +109.32%).
+
+    *** 2026-04-21 UPDATE: V23 TRUE 400d result confirmed with correct pipeline ***
+    V23 400d TRUE: +146.09%, DD -13.66%, Sharpe 2.33 (vs v9: +101.01%, DD -17.20%, Sharpe 1.99)
+    V23 STRICTLY DOMINATES Safe v9 on 400d in return (+45pp), DD (+3.5pp better), and Sharpe.
+    "Risk-adjusted superior" claim is ONLY valid on 200d window. On 400d, V23 is also safer.
+    V23 is the absolute champion. v9 remains valid as 200d conservative alternative only.
