* clean-ws-pollution.cjs —— 清理"平台安装插件"在用户工作区留下的污染（档案 28）
|
|||
|
|
*
|
|||
|
|
* 白名单（精确匹配，绝不碰其它内容）：
|
|||
|
|
* ws/.local pnpm store（旧 HOME=<ws> 造成）
|
|||
|
|
* ws/.cache pnpm metadata 缓存
|
|||
|
|
* ws/.poc-backup PoC 备份
|
|||
|
|
* ws/poc PoC 源码副本
|
|||
|
|
* ws/*.tgz 安装用插件包（现在改为直接用 /opt/dsh/artifacts/ 不再复制）
|
|||
|
|
*
|
|||
|
|
* 用法：
|
|||
|
|
* node clean-ws-pollution.cjs # dry-run（默认，只打印）
|
|||
|
|
* node clean-ws-pollution.cjs --apply # 实际执行：mv 到 <userRoot>/trash/<日期>-ws-pollution/
|
|||
|
|
* node clean-ws-pollution.cjs --apply --user-id <uuid>
|
|||
|
|
* 动作是**移动**（同盘 mv，秒级、可恢复），不是删除。
