"""strategy_executor.py — 策略执行调度器（2026-08-13 温区自适应核心）
|
||
|
||
核心（老莫要求）：根据当前温区激活策略，调度对应的选股/买卖/重评任务。
|
||
|
||
温区自适应数据流：
|
||
regime_tracker(K=5 平滑温区) + temp_band(温度) + regime_perf(实测)
|
||
→ strategy_router(当前温区激活策略 strategy_weights.json)
|
||
→ strategy_executor(按激活策略调度对应 scanner/监控/重评)
|
||
|
||
调度逻辑：
|
||
- 读 strategy_weights.json 的 active（当前温区激活策略集合）
|
||
- 对每个激活策略，调度其对应的选股扫描器（scanner）
|
||
- 非激活策略的 scanner 不跑（温区休眠）
|
||
|
||
策略→scanner 映射：
|
||
v_weak → mr_scanner.py （choppy/trend_down 超跌确认）
|
||
v_oversold → predictive_oversold_scanner.py（trend_down 预测超跌反弹）
|
||
s2_panic → s2_scanner.py （trend_down 恐慌买超跌）
|
||
v_mr/v_mr_sel → mr_scanner.py （复用 v_weak 扫描器，同家族）
|
||
v_next4/v8.1 → leader_scanner.py （trend_up 龙头识别）
|
||
|
||
用法：cron 每30分钟盘中跑（替代各 scanner 分散 cron）
