+# Statistics 模块业务逻辑
+
+## 模块职责
+
+Statistics 模块负责登录后的数据 Tab，展示当前景区下的订单统计看板。
+
+当前同步旧工程数据页的主要能力：时间段切换、统计汇总卡、每日明细、分页加载和下拉刷新。
+
+## 核心对象
+
+- `StatisticsView`：数据 Tab 根视图，读取当前景区、当前角色和统计 API。
+- `StatisticsViewModel`：管理时间段、汇总数据、每日明细、分页状态和加载状态。
+- `StatisticsAPI`：封装摄影师和景区管理员两套统计接口。
+- `StatisticsPeriod`：表示今日、昨日、7日、本月四个快捷时间段。
+
+## 数据流程
+
+页面从 `AccountContext.currentScenic` 获取当前景区 ID。缺少景区时显示空状态，不请求接口。
+
+切换时间段时同时请求汇总接口和第一页日数据接口。汇总接口使用 `range` 参数，日数据接口使用 `start_time`、`end_time`、`page` 和 `page_size`。
+
+`roleId == 53` 时使用景区管理员接口，其他角色使用摄影师接口。日数据响应使用 `DataListPayload` 解码，兼容后端返回 `data` 或 `list` 字段。
+
+## 分页规则
+
+每日明细第一页随刷新或时间段切换加载。列表滚动到底部后，如果当前数量小于 total，则继续加载下一页。加载更多失败时保留已有数据和当前页状态。
