Higher = more risk-off. The score sets the risk-asset weight via graded bands (below), with a 5-day debounce to cut whipsaw.分数越高越偏避险。该分数通过分级区间（见下）设定风险资产权重，并有 5 日缓冲以抑制频繁换仓。
What is driving the score分数由什么驱动
Each leg adds points to the 0–100 score (renormalised weighted mean). The bar is the current score, split by contribution.各分项为 0–100 分数贡献分值（归一化加权平均）。下方进度条为当前分数，按贡献拆分。
Filled width = the score out of 100. Empty = headroom (calm).填充宽度 = 满分100中的得分。空白 = 余量（平静）。

Growth of $1 (log) — vs buy & hold1美元增长（对数）— 对比买入持有
Underwater (drawdown) — vs buy & hold水下回撤 — 对比买入持有
Honest framing: this does NOT reliably beat buy-and-hold on CAGR — sitting in the cash leg through stress gives up some carry. The edge is the higher Sharpe and the much shallower max drawdown: it times the LEFT TAIL that destroys the yield (the recession/credit/rate shock), not the yield itself.诚实说明：本策略在年化收益上并不稳定跑赢买入持有 —— 压力期退守现金腿会让出部分套息。优势在于更高的夏普与明显更浅的最大回撤：它择时的是吞噬收益的左尾（衰退/信用/利率冲击），而非收益本身。

A new band must hold 5 trading days before it takes effect (hysteresis kills whipsaw). Bands and leg weights are pre-registered, not tuned per result.新区间须连续保持 5 个交易日才生效（滞后机制抑制频繁换仓）。区间与分项权重为预先登记，非按结果调参。

A handful of independent ≥20% bears govern a get-out / get-back-in switch — effective-N, not the day count, bounds confidence. Full leave-one-crisis-out validation is a fast-follow.少数几次独立的 ≥20% 熊市决定一次离场/再入场切换 — 决定置信度的是有效样本量，而非天数。完整的留一危机验证为后续跟进。
Brent crude (BZ=F) total return = dividend/coupon-adjusted close (2007→). Brent (not WTI) avoids the 2020 negative-price artifact; oil pays no income. Experimental — full Phase-0 (leave-one-crisis-out, deflated-Sharpe) is a fast-follow.布伦特原油 (BZ=F)总回报 = 经分红/票息调整收盘价（2007→）。用布伦特（非 WTI）以规避 2020 年负价格异常；原油无票息。 实验性 —— 完整 Phase-0（留一危机、贬值夏普）为后续跟进。
