 SOXL/SOXX trend-income 的 research backtest 可以使用本地价格数据运行。默认研究路径会构建 runtime 策略使用的 SOXX RSI 和 Bollinger-band 输入；也可以通过动态 RSI 分位、Chandelier-style delever overlay 等参数研究替代保护机制。Chandelier overlay 默认关闭，只在研究回测中把触发日的 SOXL target value reroute 到 BOXX，不改变生产 manifest。初始研究说明见 `docs/soxl-soxx-chandelier-stop-research.md`。
