  key_decisions:
    - decision: "使用 StrategyType 替代 RetrievalStrategy 避免与 metadata.py 命名冲突"
      reason: "metadata.py 中已存在 RetrievalStrategy 枚举"

    - decision: "ModeRouter 作为模式路由，支持 direct/react/auto 三种模式"
      reason: "支持 ReAct 和非 ReAct 两种执行路径"

      reason: "简化 dialogue.py 的集成复杂度"
      impact: "dialogue.py 只需调用 integration.execute(ctx)"
