"""助手按需查看表结构：查看服务的表这一类（look 文档 §2.4 D2、D3、D6，§2.5.3–§2.5.7）。
|
||
|
||
以前每一轮开始前服务端按库的大小挑表、塞进 system；现在 system 里每个库一行概览，模型要看表时输出一行 look，
|
||
查看服务一次给齐。这组守的是（合成景区库：入园记录和渠道之间要经关联表 channel_visits）：
|
||
|
||
- 概览：每个库一行，不列表名、不列字段；现有工作流用到的表只列名字
|
||
- 点名直取，不调挑选模型；只给需求时候选不超过 12 张全给，否则按需求挑（关思考、额度小）
|
||
- 补两跳以内的中间表，合计不超过 16 张；连接条件、连接路径、数据目录照抄；推断的标出来，驳回的关系不用
|
||
- 挑选失败（报错、超时、挑出的表都不存在、回复认不出）交回表目录（status=index），挑出来是空的照实说
|
||
- 没找到的点名、认不出的库名写进结果和记录；限定的数据源之外的不看
|
||
- 遮罩列只给列名和类型（D6），db_schema__ 和 /schema 接口是同一份说法
|
||
- 字数上限之外的表只给字段名；同一批表这一轮看过就不再重排
