+## Safety Rules
+- **Branch safety**: If the current branch is NOT a dev branch (name does NOT contain `feat`, `refactor`, `docs`, `fix`), do NOT commit directly — warn the user first.
+- **Commit SOP**: Before every `git commit`, run `git branch --show-current`. If the branch is not a dev branch, ask the user for a branch name, create it, and commit there.
+- **Branch naming**: Dev branches must contain `feat`, `refactor`, `docs`, or `fix`.
+- **CHANGELOG**: Core changes → `docs/CHANGELOG.md` only. Higher versions on TOP, lower versions below.

+# Changelog / 更新日志
+
+All notable changes to this template should be documented in this file.
+本模板的重要变更建议统一记录在此文件中。
+
+The format loosely follows Keep a Changelog and can be adapted to the team's habits.
+本文档参考了 Keep a Changelog 的思路，也可以根据团队习惯调整。
+
+## [0.0.0] - 2026-08-02
+
+### Notes / 说明
+
+- The repository currently provides structure and placeholder files rather than a finished implementation.
+- 当前仓库主要提供目录结构和占位文件，尚不是一个已完成功能实现的成品项目。
+
+- Future updates should record framework selection, startup steps, deployment workflow, and major documentation changes.
+- 后续若补充了技术栈、启动流程、部署方式或重要文档内容，建议继续记录在本文件中。
