"""评测从头到尾（细案 01 测试 test_eval_e2e）：dual_check_shop 的虚构订单库 + 剧本模型。

题目是「9/1–9/7 按支付日、不含退款的销售额」，期望 SQL 算出 330。助手剧本只在查看结果里看到数据目录写着「按支付日期归属」
时才按支付日写（330），没看到就按下单日写（310）。所以：

- 臂「当前目录」按支付日答 330：通过、可追溯、答案的 SQL 和期望 SQL 等价已证明（逐题 E1）；
- 臂「关目录」按下单日答 310：不通过，差异方面是 time；
- 「目录贡献」对照（当前 vs 关）的配对表是 1:0，两臂共用期望（同一份期望运行）；
- 再评一次（把目录里的业务日期去掉）和上一次比：这题从通过变成不通过，归因「做法变」，指纹里目录快照变了。

评测运行的来源都是 eval，不进使用统计；运行名「评测：题集名·第 n 题」。
