"""T09 预审运行视图的只读存储：把装配好的 ScreeningRun 投影存下来供界面读取。
|
|||
|
|
|
|||
|
|
依据：docs/v2/03-detailed-design.md §9.2、BR-13；AC-12/30。
|
|||
|
|
|
|||
|
|
**不新建表**：复用既有 `assistant_objects`（新 kind `prescreen_run`），旧库结构不变。
|
|||
|
|
运行视图是既有 run 对象的**只读投影**，因此这里只提供保存与读取，
|
|||
|
|
不提供就地修改：要改结果必须产生新的运行修订（BR-13：过程修订不覆盖旧结果）。
