一、问题(本轮实测)
`draw-ui` 与 `oil-motion` 目录里**各自带一个内嵌 `.git`** ⇒ 上一次提交把它们记成了 **gitlink(子模块指针)**
⇒ 仓库里只存了一个不属于任何远端的 commit id,**别人克隆下来这两份是空的** ✗(`git status` 显示 ` m draw-ui` / ` m oil-motion` = 子模块内容有改动)。
二、处置(可回退)
· 把两处的 `.git` **挪走**(⛔ 不是删除)⇒ `归档/内嵌git-20261008/{draw-ui,oil-motion}.git`;
· `git rm --cached` 掉那两个 gitlink,再 `git add` 两个目录 ⇒ **按正常文件入库**(内容才真的进仓库)。
三、副作用(如实记)
挪走 `.git` 后,这两个技能**不能再原地 `git pull` 取上游更新**(要更新得重新拉一份覆盖);
如需恢复其本地仓库,把 `归档/内嵌git-20261008/` 里的 `.git` 挪回原处即可。
