 ## 更新流程
 
-1. 在 mpv 中按 `M` 触发 manager.lua，观察控制台输出，确认无 `FAILED` 条目
-2. 更新完成后删除 manager 在子目录留下的嵌套 `.git`（否则 `git add` 会失败）：
+1. 在 mpv 中按 `M` 触发 manager.lua，观察控制台输出，确认无 `FAILED` 条目。可能会有其他报错如 `[manager] Fehler: externes Repository manager existiert bereits.`，这是正常的。只需要确保不出现全大写的 `FAILED` 即可。
+2. 将 manager.lua 在 dest 目录产生的嵌套 `.git` 目录迁移到仓库内的 `.manager/`（避免根仓库误判为 submodule，幂等可重复执行）：
    ```bash
-   find -L ~/.config/mpv -mindepth 2 -name .git -type d | sort -r | xargs rm -rf
+   REPO=$(git -C ~/.config/mpv rev-parse --show-toplevel)
+   GITSTORE="$REPO/.manager"
+   mkdir -p "$GITSTORE"
+   find -L ~/.config/mpv -mindepth 2 -name .git -type d | while read gitdir; do
+       dest="${gitdir%/.git}"
+       rel="${dest#$REPO/}"
+       name=$(echo "$rel" | tr '/' '-')
+       mv "$gitdir" "$GITSTORE/$name"
+       depth=$(echo "$rel" | tr -cd '/' | wc -c)
+       ups=$(printf '../%.0s' $(seq 1 $((depth + 1))))
+       echo "gitdir: ${ups}.manager/$name" > "$dest/.git"
+   done
    ```
 3. 重启 mpv，检查控制台有无 `unknown key` 或脚本加载失败的警告
 4. 若有 `unknown key` 警告，说明对应脚本的配置项发生变化，找 `script-opts/` 下同名 `.conf` 对照脚本源码更新
