+
+                您的 PR 未通过检查清单校验 —— 检测到您勾选了「我**没有**认真阅读以上内容，直接提交」。
+
+                请按照以下规则重新提交 PR：
+
+                1. 请仔细阅读 PR 模板中的所有说明。
+                2. 本次开发请**基于 \`dev\` 分支**进行，并将 PR 目标分支设置为**开发分支（\`dev\`）**（除非极其紧急的情况才允许合并到主分支）。
+                3. 完成上述检查后，请重新发起 PR。
+
+                本 PR 已自动关闭，请按规范重新拉起。感谢您的贡献！🙏

+
+                Your PR failed the checklist validation — the item "I **did not** read the above carefully before submitting" was checked.
+
+                Please follow these rules and reopen a new PR:
+
+                1. Read all the instructions in the PR template carefully.
+                2. Make sure your development is **based on the \`dev\` branch**, and set the PR target branch to the **development branch (\`dev\`)** (only merge to main if extremely urgent).
+                3. Once you have reviewed everything, please open a new PR.
+
+                This PR has been automatically closed. Please reopen a correct one. Thank you for your contribution! 🙏
