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。
