- Agent 两次引用的行号相同、都不是整份结果时，一边引用了的维度值（区域……）在另一边的快照里却没被引用（按区域排序多了北区、按金额取前 3 名名次变了），判为说不清，说明写出是哪个维度值、在第几行；不再把还在快照里的区域算成「数据没了」、给出远超 100% 的占比。另一边快照里真的没有了的照常是数据变化。数组字段里的单个元素同样核对。维度按两边整份结果认，遮罩列不拿来认，分不出维度的仍按行号认 - 两边都记不出写入者时，范围从整张图改为口径卡之前可能执行过的节点（它的上游加并行支路）：口径卡自己、只在它下游的写周报写不了它读到的值，不再被点名成来源；并行支路上的节点不说成「上游」 - 「整份结果」统一按引用了哪几行判断，容器一支不再单列 - 默认设置登记表的核对测试改为按节点类型：从各执行器出发顺着用到的函数（含就地 import、回调、类）找 cfg 读法，在字面量元组上循环读的键名认得出，认不出的变量键名直接失败；核对节点模块里每个读配置的函数都走到了，登记了不读的也算错。据此补登记成果节点出具契约读的报告节点三项（evidence_from、metrics_from、entities） - 补测试守住上一轮的几条规则：Agent 交的不同而代码节点的数没变是没变，只有这次运行的快照读不出来时说这次，默认设置同时改了结论句裁判时 Agent 只写模型，调不调模型由默认设置决定，报告节点在代码节点上游，改了几个节点时点名画布上靠前的

"""运行对比的纯函数（engine/compare.py）：同一个工作流的两次运行，每个指标的变化拆成数据、口径、模板 / SQL。
|
||
|
||
两次运行都是照真实运行的事件形状手写的虚构数据（区域、金额、日期都是编的）：取数节点 fetch 查一条按区域汇总的
|
||
SQL，Agent 节点 bot 自己再查一次、把各区域的金额作为数组字段交给口径卡，口径卡算几个指标。工件放在字典里。守的是：
|
||
- 只数据变（SQL 一字不差、结果变了）是 data_only；只改日期字面量是 params_only；SQL 结构变了是 sql_changed、不拆
|
||
- 口径变了（表达式、口径版本）是 caliber_and_data：旧表达式的叶子路径在这次的输入里都取得到时严格拆分，
|
||
口径效应 + 数据效应 = 总变化（逐位相等）；取不到就不拆，说明缺的是哪一个
|
||
- 维度归因：按维度键配对两边的行，按变化的绝对值取前 10；度量列之和等于输入的值（两边都等）才给占比，占比之和
|
||
为 1；对不上时占比为空并说明；截断的快照不归因，照实写
|
||
- 遮罩列的值绝不出现在结果里；用到遮罩列的指标不拆分
|
||
- 模板对比：新增、删除的节点，配置有变化的节点和配置项名
|
||
- 输入的出处：合并查询追到它的上游查询；Agent 按出处交的字段还要引用同一列、同一段行（行段相同、一边是整份结果
|
||
一边不是的不算；都不是整份结果的，一边引用了的区域另一边还在快照里却没引用的也不算）；没按出处交的数、上游数据
|
||
没变数却变了的、上游的 Agent 两次交出的结果不同的，说不清变化从哪来（incomparable），记不出写入者的只看口径卡
|
||
之前可能执行过的节点；图里写死的字面量改了、连线变了、读到的默认设置变了都算模板变化
