 - 普通商务渠道 summary 累加可见行。超管渠道 summary 使用筛选范围内全局去重；模式 0 按平台前缀区分身份，模式 1 跨平台去重。
 - 付费率＝充值人数÷活跃人数×100，ARPU＝充值金额÷活跃人数，ARPPU＝充值金额÷充值人数。分母为零时为零。
 - 保留原逐行人数的 Java int 上限，游戏汇总改用 int64 避免相加溢出。相同排序值使用平台、ID 稳定排序。

+- 后端不传日期时周期为上海当天，只传一端会拒绝；前端默认近 30 天含今天。后端页长缺失、非正或超过上限时为 500，页面显式传 10。
 - 缺少必要数据表时 `available=false`、`summary=null`，顶部指标为 null，不把缺表当成零。
 
 ## 验证与优化
 
 - 使用聚合查询和批量资料查询代替逐行查询，不改变业务口径。日期非法或倒置返回明确错误。
+- 数字指标先按全部统计行计算汇总、排序和分页，再补当前页的渠道/游戏名称及商务资料；按渠道名称或渠道类型排序时仍先补全体资料。空页不读取资料，官方及未知渠道标签保持原规则。
 - 隔离 TCP HTTP 和仓储测试覆盖全量汇总与分页、跨平台同号、官方/孤立渠道、根渠道树去重、类型交集、历史游戏名过滤、当前资料展示、偏好切换及空范围。
 - 领域测试覆盖大金额精确排序、分母和人数上限。前端检查筛选回第一页、30 天默认值、汇总不随分页变化、缺数据提示、没有额外导出入口。
