我制作了「复杂度路由」的流程图，评论区没法发图片，直接上mermaid代码： graph TD subgraph "Layer 1: 任务入口" A[TaskAtom<br/>任务原子] end subgraph "Layer 2: 信号提取" B[Signal Extractor<br/>提取路由信号] C[intent<br/>任务意图] D[evidence_state<br/>证据状态] E[mechanical_ready<br/>执行对象状态] F[risk<br/>动作风险] SF[Signal Fusion<br/>信号融合] end subgraph "Layer 3: 路由决策" G[RouteDecision<br/>控制契约] end subgraph "Layer 4: 推理执行" H[lane<br/>工作流车道] N[简单诊室<br/>一句话回答] O[CoT诊室<br/>思维链推理] P[并行探索诊室<br/>多路径并行] Q[迭代假设验证诊室<br/>多轮验证] end subgraph "Layer 5: 验证闭环" R[Validator<br/>验证器] S{验证结果} T[输出结果] U[换路/升级/转人工] end subgraph "Layer 6: 输出观测" V[最终输出] W[路由日志] X[成本账单] Y[质量评分] end A --> B B --> C B --> D B --> E B --> F C --> SF D --> SF E --> SF F --> SF SF --> G G --> H G --> I[reasoning_mode<br/>推理拓扑] G --> J[reasoning_effort<br/>推理深度] G --> K[budget<br/>预算] G --> L[human_gate<br/>人审闸门] G --> M[model_policy<br/>模型策略] H --> N H --> O H --> P H --> Q N --> R O --> R P --> R Q --> R R --> S S -->|通过| T S -->|不通过| U U -->|重新进入| G T --> V T --> W T --> X T --> Y
