+### 5.3 当前严格执行流
+
+当前版本已不再把“地址解析是否足够精确”和“deep link 是否能生成”完全交给模型决定。
+
+当前执行流如下：
+
+1. 服务端先对起点、终点、所有途经点做前置解析
+2. 每个点都必须成功完成：
+  - `maps_text_search` 命中精确 POI
+  - `maps_search_detail` 返回稳定坐标
+  - 取得 `poi_id`
+3. 任意一个点解析模糊、缺少 `poi_id`、或地理结果交叉校验失败，直接返回错误
+4. 只有在所有点都通过后，才把“预解析点位 JSON”交给 Agent
+5. Agent 只负责候选顺序、逐段驾车计算、最佳路线选择、summary 和 warnings
+6. 服务端最后再直接调用 `maps_schema_personal_map` 生成 deep link
+7. 如果 deep link 生成失败，则整个请求失败
