 当前正式模型只有一个：[`artifacts/v1/model.joblib`](artifacts/v1/model.joblib)。它由最近 18 根 8H K 线预测未来 6 根 8H K 线的稳健低点收益，并输出点预测以及用于区间参考的 q20/q80 结果。根目录不放置历史实验模型；历史实验说明保留在 [`docs/v0_0823.md`](docs/v0_0823.md) 和 [`docs/v1_0823.md`](docs/v1_0823.md)。

 回撤列是收益的相反数：预测收益为负时表示价格可能低于当前收盘；预测收益为正时，回撤列可能为负，表示未来稳健低点仍高于当前收盘。模型不满足资格条件时，预测字段为空，不应把空值当作零回撤。
