 """A 股选股过滤器(ST/停牌/科创北交/次新/涨跌停)。
 
 聚宽全天候策略用到的 filter_* 函数的本地实现。
-聚宽原版用 ``get_current_data()`` 拿快照,我们用注入的 provider 拿同样的字段。
 
 设计:接受一个 ``provider`` 参数(duck typing),不依赖具体类。
 provider 需要提供:
 - ``get_security_info(code, date)`` → {"display_name", "name", "start_date", ...}
-- ``get_current_tick(code)`` 或 ``get_live_current(code)`` → {"paused", "high_limit", "low_limit", "last_price"}
+- ``get_limit_status_batch(codes, date)`` → {code: {"is_limit_up", "is_limit_down",
+  "is_paused"} | None}  (**回测涨跌停/停牌判断,数据 session 真实计算**)
 - ``get_price(code, end_date, frequency, fields, count, panel=False)`` → DataFrame
 
-bullet-trade 的 MiniQMTProvider 全部满足,且本模块测试用 MagicMock 也能跑。
+⚠️ 涨跌停/停牌 filter(2026-07-29 重构):
+原实现用 ``get_current_tick().last_price/high_limit`` 判断,但回测 provider 的 tick
+dict **没有这些字段** → 恒 None → 三个 filter 全失效(回测照买涨停/照卖跌停/照交易
+停牌,03 动量策略因此算出 160758% 假收益)。改用数据 session 交付的
+``get_limit_status_batch`` 批量预取**已判断好的状态**(方案 A),filter 只做取舍。
+
+向后兼容:``status_map`` 与 ``date`` 都不传 → 无法判断 → 保留所有股票(等价原失效
+行为,all_weather 本次不动)。
