 **正确做法：外置脚本，workflow 只做调用。**

-    path: xw-console

+# ✅ 正确 — 外置 Python 脚本（放在 infra repo，通过已有 checkout 引用）

-脚本存放在 `scripts/` 目录，命名规范 `动词_名词.py` 或 `动词-名词.sh`。
+渲染脚本存放在 `ai-workspace-infra/iac_modules/terraform-hcl-standard/vultr-vps/scripts/`，
+通过 workflow 内已有的 `Checkout iac_modules` 步骤引用，无需额外 self-checkout。
+workflow 内的 `run:` 块调用外置脚本，命名规范 `动词_名词.py` 或 `动词-名词.sh`。
