-# 贡献与工程约束
-
-## 本地验证
-
-项目要求 Node.js `20.19` 至 `24.x`。后端与 Web 前端分别维护锁文件，依赖变更后必须同步提交对应的 `package-lock.json`。
-
-```bash
-cd backend
-npm ci
-npm test
-npm audit --omit=dev
-
-cd ../frontend
-npm ci
-npm run build
-npm audit
-```
-
-开发 Web 前端时分别运行后端 `npm run dev` 与前端 `npm run dev`。生产环境只服务 `frontend/dist/`，不要手工修改构建产物或给资源 URL 追加版本号。
-
-## 不可破坏的约束
-
-1. `app.use(expressErrorHandler)` 必须保持为最后一个 `app.use`；CI 的架构测试会检查这一点。
-2. Express 4 使用 `express-async-errors` 捕获异步路由拒绝；该补丁必须在注册任何路由前加载。
-3. 限流器、下载安全计数和 OSS 用量缓存仍是进程内状态，PM2 必须保持单实例 `fork` 模式。扩容前先迁移到共享状态存储。
-4. `npm ci` 依赖严格同步的 lock 文件；禁止在部署脚本中删除 `package-lock.json`。
-5. Express 中间件顺序是安全边界：requestId/安全头/CORS/HTTPS/静态资源/API 限流/请求体/CSRF，不得无验证调整。
-6. 桌面安装包目录 `frontend/downloads/` 是运行时发布目录，更新前必须备份且不得放进 `frontend/dist/` 的清理生命周期。
-7. 桌面安装包必须作为 Gitea Release 附件发布；Git 只提交 `frontend/desktop-release.json`，禁止提交 `.exe`。
-8. 更新 Release 元数据时必须核对标签、文件名、字节数和 SHA256，并运行 `npm run check:desktop-release`。
-
-## 改动原则
-
-- 路由继续按业务域渐进迁移，每次只迁移一个域并运行全部测试。
-- 新抽取的纯函数必须直接测试生产模块；禁止在测试文件复制实现。
-- 安全或配额核心逻辑应做一次变异验证：临时改坏生产实现，确认对应测试失败后立即还原。
-- 日志使用 `req.log` 或公共 logger，禁止记录密码、令牌、Cookie、Access Key 或完整授权头。

-### 1. 修改 API 基础地址
-
-当前默认地址在 `desktop-client/src/App.vue`：
-
-- `appConfig.baseUrl`（默认 `https://cs.workyai.cn`）
-
-改成你的服务地址后重新运行/打包。
-
-### 2. 后端需提供的核心接口
-
-桌面端通过现有 Web API 工作，至少需要这些接口：
-
-- `POST /api/login`
-- `POST /api/logout`
-- `GET /api/user/profile`
-- `GET /api/files`
-- `GET /api/files/search`
-- `POST /api/files/mkdir`
-- `POST /api/files/rename`
-- `POST /api/files/delete`
-- `POST /api/share/create`
-- `GET /api/share/my`
-- `DELETE /api/share/:id`
-- `POST /api/direct-link/create`
-- `GET /api/client/desktop-update`
-- 分片上传相关接口（客户端走 `api_upload_file_resumable`）
-
-### 3. 鉴权与跨域要求
-
-- 使用 Cookie / Session 鉴权
-- 服务端允许桌面端跨域并携带凭据（credentials）
-- 建议启用 HTTPS
-
-## 构建打包
-
-```bash
-cd desktop-client
-npm install
-npm run tauri build
-```
-
-构建产物示例：
-
-- `desktop-client/src-tauri/target/release/bundle/nsis/*.exe`
-
-## Linux 交叉编译 Windows（x64）
-
-```bash
-cd desktop-client
-rustup target add x86_64-pc-windows-gnu
-npm run tauri build -- --target x86_64-pc-windows-gnu
-```
-
-如需生成安装包，请确保系统安装 `mingw-w64` 与 `nsis`。
-
-## 更新发布接入（与本项目后端配合）
-
-1. 把新安装包上传到服务端下载目录（示例：`frontend/downloads/`）。
-2. 在后台设置中更新：
-   - `desktop_update.latest_version`
-   - `desktop_update.installer_url`
-   - `desktop_update.release_notes`
-3. 客户端会通过 `GET /api/client/desktop-update` 检查更新并下载新包。
-
-## 常见问题
-
-### Q1：改了接口地址但还是连旧地址？
-
-确认修改的是 `desktop-client/src/App.vue` 中的 `appConfig.baseUrl`，并重新构建。
-
-### Q2：为什么更新接口返回有新版本，但客户端不弹更新？
-
-检查：
-
-- `latest_version` 是否确实大于客户端当前版本
-- `installer_url` 是否可访问
-- 客户端能否访问后端 `desktop-update` 接口
-
-### Q3：分享/直链重复创建问题
-
-当前后端已支持“同一用户同一路径复用已有链接”。若要生成新链接，请先删除旧链接再创建。
