- 归档4个B组模块: strategy_tree.py/branch_evaluator.py/prune_branches.py/branch_scanner.py 按方法论：只有重评才能改信号和操作，B组的分支扫描/评估/剪枝越权 - stale_push_wlin.py: detect_scenario→market_regime.load_market_regime() - strategy_lifecycle.py: detect_scenario→market_regime.load_market_regime()，筹码权重改用温区 - import_holding_xls.py: 移除init_default_branches调用(分支概念已移除) - per_stock_reassess.py: 移除init_default_branches调用(分支概念已移除) - 清理mofin_db.py/strategy_lifecycle.py残留注释引用 - 关键脚本语法全部通过

prune_branches.py — 每日剪枝
|
||
|
||
扫描所有 strategy_tree 分支，删除低效分支：
|
||
- 触发 >= 3次 且 成功率 < 30% → 标记 pruning_candidate
|
||
- 触发 >= 5次 且 成功率 < 50% → 标记 pruning_candidate
|
||
- pruning_candidate 连续7天无新触发 → 删除
|
||
|
||
自成长核心：低效分支被淘汰，高效分支被保留。
|
||
数据写入 decisions.json 的 strategy_tree.branches[]。
