"""合并两条分支的迁移头。
|
|||
|
|
|
|||
|
|
背景：`qyqy_develop` 与 `yc` 两条线各自补齐了一次"撤下配置发布自审约束"的迁移
|
|||
|
|
（`20260910_drop_review_separation` 与 `20260911_drop_review_separation`），
|
|||
|
|
导致合并后 alembic 出现两个 head。两者都先查 `information_schema` 再决定是否
|
|||
|
|
`ALTER`，重复执行安全，因此全部保留，只用一个空的合并 revision 把图收敛为单 head。
|
|||
|
|
|
|||
|
|
本迁移不改任何表结构：`upgrade`/`downgrade` 都是空操作。
