 Runner online 后，第一次 push 只执行 `Controller CI`，不会创建实例或产生 AutoDL 费用。
 
+## 阿里云长期部署
+
+每次 push 到 `main` 后，`Controller CI` 会先运行测试，再把通过验证的控制器安装到：
+
+```text
+/opt/ces-controller/releases/<git-commit>/
+```
+
+`/opt/ces-controller/current` 原子指向当前版本，并安装 Terminal 入口
+`/usr/local/bin/ces-controller`。管理 workflow 只执行这个长期部署的版本，并拒绝执行与当前
+workflow commit 不一致的旧版本。部署目录不保存 AutoDL Token 或 Runner Registration Token；
+Secret 仍只在单次 Actions 任务中注入。

+通过 SSH 可以检查版本或查看帮助：
