-## 注意事项
+## 9. 注意事项
 
-1. API 仅监听本地地址 `127.0.0.1`，不对外网开放
-2. 需要先连接数据库才能查询数据
-3. 时间参数格式为 `YYYYMMDD`（如 20260205）
-4. 支持 CORS，可从浏览器前端直接调用
+1. API 仅监听本机 `127.0.0.1`，不对外网开放。
+2. 使用前需要先在 WeFlow 中完成数据库连接。
+3. `start` 和 `end` 支持 `YYYYMMDD` 与时间戳；纯 `YYYYMMDD` 的 `end` 会扩展到当天 `23:59:59`。
+4. 群成员的 `groupNickname` 依赖微信源数据；源数据缺失时不会自动补出。
+5. 媒体访问链接只有在对应消息已经通过 `media=1` 导出后才可访问。
