-## 1. 基本原则
-
-- 适用范围：仓库根目录及所有子目录
-- 优先级：用户明确指令 > 本文件 > 默认实现习惯
-- 若与用户要求冲突：先执行用户要求，并在变更说明中标注偏离点
-
-## 2. 固定技术栈
-
-- 后端：Golang + Iris + GORM + github.com/mlogclub/simple
-- 数据库：同时兼容 SQLite 和 MySQL
-- 前端：Next.js(App Router) + React + shadcn/ui + Tailwind CSS
-- 前端包管理器：pnpm
-
-## 3. 后端分层
-
-必须遵循单向依赖：models -> repositories -> services -> controllers
-
-- models：只定义实体和表映射
-- repositories：只封装数据访问
-- services：负责业务规则、事务编排、聚合逻辑
-- controllers：只做参数解析、权限校验、service 调用、响应封装
-
-禁止：
-
-- controller 直接调用 repository
-- 直接将 GORM model 返回前端
-- 在 models/repositories 中写业务编排
-
-## 4. simple 使用约定
-
-- DB 初始化后必须执行：sqls.SetDB(db)
-- 查询条件优先使用：sqls.Cnd
-- 参数绑定优先使用：web/params
-- HTTP 响应统一使用：web.JsonData、web.JsonPageData、web.JsonError
-
-## 5. 数据库兼容规则
-
-- 字段类型使用兼容集合：varchar、text、int、bigint、datetime
-- 主键统一使用 int64
-- 避免数据库私有语法和方言特性
-
-## 6. 接口与 DTO
-
-- DTO 分离：request / response 分开定义
-- JSON 字段统一使用 camelCase
-- 禁止透传底层 SQL 错误
-- controller 入参使用 request DTO
-- controller 出参使用 response DTO
-- 禁止直接返回 models 到前端
-
-## 7. Go 代码规范
-
-- 日志统一使用标准库 log/slog
-- 新增 Go 代码统一使用 any，禁止新增 interface{}
-- 修改 Go 代码后必须执行 gofmt
-
-## 8. 前端规范
-
-- 前端目录：web
-- 框架：Next.js 16 + App Router
-- 基础组件优先使用 shadcn/ui
-- 前端业务接口统一通过 web/lib/api/* 发起，禁止页面里散落裸 fetch
-- 新增或修改前端页面后至少执行：cd web && pnpm typecheck
-
-## 9. 提交前检查清单
-
-每次修改后至少确认：
-
-1. 没有跨层调用或反向依赖
-2. 写操作有明确事务边界
-3. 返回仍符合统一 JsonResult 结构
-4. 兼容 SQLite 与 MySQL
-5. 补充了必要测试，至少覆盖 service 核心路径
-6. Go 改动已执行 gofmt
-7. 前端改动至少通过 pnpm lint 或 pnpm typecheck（在 web 目录）`
