+# Team: software-xiaocai-v2
+
+小菜记账 (XiaoCai Bookkeeping) 微信小程序 v2 迭代团队。
+
+## 目标
+
+完成 v2 全量迭代：安全性修复、代码质量重构、性能优化、UX 增强、测试体系建设、新功能开发。
+
+## 任务总览
+
+| 任务 | 优先级 | 状态 | 依赖 | 描述 |
+|------|--------|------|------|------|
+| T01-remaining | P0 | pending | 无 | 完成安全修复剩余项 (S1, S5, S6, S7, 基础设施) |
+| T02 | P1 | pending | T01 | 代码质量重构 (C1-C9, 通用组件抽取) |
+| T03 | P1 | pending | T01 | 性能优化与 UX 增强 (Perf-1~7, UX-1~7) |
+| T04 | P1 | pending | T01 | 测试体系建设 (后端集成测试 + 前端 Store 测试) |
+| T05 | P1 | pending | T01 | 新功能 (财务报告推送 + 预算预警) |
+
+## T01 已完成项
+
+- S2: logs.ts SQL 参数化 (LIMIT/OFFSET 改为 ? 占位符)
+- S3(部分): TOKEN_SECRET 启动校验 checkTokenSecret()、backup.ts JWT_SECRET→TOKEN_SECRET、Access Token 有效期缩短为 2h
+- S4: 导出下载使用 HMAC 签名短期凭证 (/prepare 端点)
+
+## T01 剩余项
+
+- S1: .env 凭据泄露修复 (轮换凭据 + git-filter-repo + pre-commit 钩子)
+- S3(完善): TOKEN_SECRET 集中到 config/token.ts，移除 auth.ts 内联 fallback
+- S5: Refresh Token 双 Token 机制 (refresh_tokens 表 + 前端 401→refresh→重试)
+- S6: 软删除 (users.deleted_at + admin 恢复接口 + 全局查询过滤)
+- S7: DB 连接移除默认凭据 (connection.ts 移除 || 'localhost' 等 fallback)
+- 基础设施: .env.test、jest.config.js、vitest.config.ts
+
+## 并行策略
+
+T01 完成后，T02/T03/T04/T05 可并行推进。注意 T02 与 T03 有轻微文件冲突 (stores/)，建议 T02 先行或约定合并策略。

+# 小菜记账 增量架构设计文档
+
+> 版本：v1.0 | 架构师：高见远（Gao） | 日期：2025-07
+
+---
+
+## Part A: 系统设计
+
+### 1. 实现方案 + 框架选型
+
+#### 1.1 分类拖拽排序（P0-1）
+
+**技术挑战**：微信小程序不支持 HTML5 Drag and Drop API，Uni-app 的 `movable-area`/`movable-view` 适合单元素拖拽而非列表重排。
+
+**方案**：基于 Touch 事件的自定义拖拽排序组件 `DragSortList`。
+
+- 监听 `@touchstart` / `@touchmove` / `@touchend` 三组事件
+- 拖拽时通过 `transform: translateY()` 实现元素位移动画
+- 拖拽过程中实时计算目标索引，交换数组元素位置
+- 松手后调用已就绪的 `sortCategories(ids)` API 批量更新排序
+- 支出/收入各自独立排序（复用现有 `tabType` 切换 + `currentCategories` computed）
+- **不引入第三方拖拽库**——Uni-app 小程序环境下无成熟可用方案，自研可控性更高
+
+#### 1.2 服务端导出流式响应（P2-3）
+
+**方案**：Node.js 原生 Stream + `pipeline()` 管道。
+
+- **< 1 万条**：使用 `Readable.from()` 创建内存流，逐行 push 数据，通过 `pipeline()` 管道传输到 Response
+- **≥ 1 万条**：先写入临时文件（`os.tmpdir()`），再 `fs.createReadStream()` 流式返回，完成后删除临时文件
+- CSV 格式：手动拼装（无需额外依赖），添加 BOM 头确保中文兼容
+- JSON 格式：流式写入 `[` + 逐条 `,` 分隔 + `]`，避免全量 JSON.stringify
+- Response Headers：`Content-Type: text/csv; charset=utf-8` / `application/json; charset=utf-8`，`Content-Disposition: attachment; filename=...`
+- 超时保护：流式响应不设 `express.json()` body 限制，但设 60s 超时
+
+#### 1.3 标签系统数据库设计（P3-2~4）
+
+**设计原则**：标签不区分收支类型，跨分类使用，轻量关联表。
+
+- `tags` 表：用户维度，每用户最多 20 个标签，8 色预设
+- `transaction_tags` 表：多对多关联，每笔交易最多 5 个标签
+- 标签与交易在同一事务中写入（`POST/PUT /transactions` 扩展 `tagIds` 字段）
+- 查询交易列表时 LEFT JOIN 聚合标签信息（避免 N+1 查询）
+- 统计按标签聚合使用 `GROUP BY tag_id`
+
+#### 1.4 数据导入（P2-2）
+
+**方案**：JSON 格式导入，服务端校验 + 批量写入 + 去重。
+
+- 接收 JSON 数组，校验字段格式（必填：date, type, amount, category_name）
+- 按 `date + type + amount + note` 组合去重（查现有记录比对）
+- 使用 `INSERT ... VALUES (...), (...), ...` 批量写入（每批 100 条）
+- 返回结果：`{ total, imported, skipped, errors[] }`
+
+#### 1.5 统计年度/周视图（P2-1）
+
+**方案**：后端 `period` 参数扩展 + 前端维度切换器。
+
+- 后端：`GET /stats/category` 和 `GET /stats/trend` 新增 `period=week|month|year` 参数
+  - `week`：基于当前日期计算本周一至本周日，趋势 X 轴为周一~周日
+  - `month`：保持现有行为（默认）
+  - `year`：基于当前年份 1-12 月，趋势 X 轴为 1月~12月
+- 年视图日期范围计算：`startDate = ${year}-01-01`, `endDate = ${year}-12-31`
+- 周视图日期范围计算：获取本周一和本周日
+- 趋势数据 GROUP BY 逻辑：年视图按月 GROUP，周视图按日 GROUP

+    note for TransactionTag "复合主键 (transaction_id, tag_id)\n每笔交易最多 5 个标签"
+```
+
+#### 3.1 新增数据库表
+
+**tags 表**
+
+```sql
+CREATE TABLE IF NOT EXISTS tags (
+  id INT AUTO_INCREMENT PRIMARY KEY,
+  user_id INT NOT NULL,
+  name VARCHAR(20) NOT NULL COMMENT '标签名称',
+  color VARCHAR(20) NOT NULL DEFAULT '#FF8C69' COMMENT '标签颜色',
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  UNIQUE KEY uk_user_name (user_id, name),
+  INDEX idx_user (user_id),
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+```
+
+**transaction_tags 表**
+
+```sql
+CREATE TABLE IF NOT EXISTS transaction_tags (
+  transaction_id INT NOT NULL,
+  tag_id INT NOT NULL,
+  PRIMARY KEY (transaction_id, tag_id),
+  INDEX idx_tag (tag_id),
+  FOREIGN KEY (transaction_id) REFERENCES transactions(id) ON DELETE CASCADE,
+  FOREIGN KEY (tag_id) REFERENCES tags(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+```
+
+#### 3.2 新增/修改 API 端点

+
+### 5. 待明确事项
+
+| # | 事项 | 当前假设 |
+|---|------|---------|
+| 1 | 备份下载的签名 URL 是通过新端点直接下载，还是返回签名 URL 让前端跳转？ | 采用直接下载方式：`GET /api/backup/:id/download?token=xxx`，后端校验 token 后流式返回文件 |
+| 2 | 年视图/周视图的 `month` 参数如何处理？ | 新增 `period` 参数，当 `period=year` 时 `month` 参数被忽略，使用当前年份；当 `period=week` 时使用当前周 |
+| 3 | 导入 JSON 的 `category_name` 匹配不到时如何处理？ | 归入"未分类"（category_id = NULL），不自动创建分类 |
+| 4 | 标签预设 8 色具体色值？ | 复用现有 `colorOptions`：`#FF8C69, #7BC67E, #5B9BD5, #FFD700, #FF69B4, #8B5CF6, #F97316, #06B6D4` |
+| 5 | 健康检查移到 authMiddleware 前是否影响安全？ | `/api/health` 仅返回 DB 连接状态和服务器时间，不泄露敏感信息，安全无影响 |
+| 6 | 数据导入文件大小限制？ | 前端限制 5MB，后端 `express.json({ limit: '5mb' })` 仅对导入端点放宽（当前全局 10kb） |
+
+---
+
+## Part B: 任务分解
+
+### 6. 需要新增的依赖包
+
+#### 后端 (server)
+
+```
+无新增依赖
+```
+
+> 流式导出使用 Node.js 内置 `stream`、`fs`、`os` 模块，CSV 拼装手写无需 `json2csv`，签名 URL 使用已有 `crypto` 模块。
+
+#### 前端 (client)
+
+```
+无新增依赖
+```
+
+> 拖拽排序使用 Touch 事件自研实现，不引入第三方拖拽库。
+

+
+## 一、实现方案 + 技术选型
+
+### 1.1 安全修复方案
+
+#### S1：.env 凭据泄露修复
+
+| 项目 | 方案 |
+|------|------|
+| 核心思路 | 凭据轮换 + Git 历史重写 + pre-commit 防护 |
+| 工具 | `git-filter-repo`（Python，比 BFG 更安全，支持 blob 回调替换） |
+| 防护 | `.githooks/pre-commit` 拦截 `.env` 文件提交 |
+| 回滚 | 操作前 `git clone --mirror` 完整备份 |
+| 执行顺序 | ① 轮换所有凭据 → ② 重写 Git 历史 → ③ 强制推送 → ④ 验证 .gitignore |
+
+#### S2：logs.ts SQL 拼接修复
+
+| 项目 | 方案 |
+|------|------|
+| 当前问题 | `LIMIT ${pSize} OFFSET ${offset}` 模板字符串直接拼接 |
+| 修复方案 | `parseInt` + 范围校验后使用 `pool.query` + `?` 占位符 |
+| 关键点 | `pool.query` 支持 `?` 占位符用于整数参数；`pool.execute` 的 prepared statement 对 LIMIT/OFFSET 类型要求严格，故选用 `pool.query` |
+
+#### S3：TOKEN_SECRET 弱默认值 + 命名不一致
+
+| 项目 | 方案 |
+|------|------|
+| 核心思路 | 新增 `server/src/config/token.ts` 集中管理，移除所有 fallback |
+| 命名统一 | `backup.ts` 中 `JWT_SECRET` → `TOKEN_SECRET`；所有引用改为 `import { TOKEN_SECRET } from '../config/token'` |
+| 启动校验 | `TOKEN_SECRET` 未设置或长度 < 32 时 `process.exit(1)` |
+| 密钥生成 | `openssl rand -hex 32` 生成 64 字符强密钥 |
+
+#### S4：Export/Backup 短期一次性下载凭证
+
+| 项目 | 方案 |
+|------|------|
+| 核心思路 | 新增 `download_tokens` 表，生成随机凭证（`crypto.randomBytes(32)`） |
+| 有效期 | 5 分钟，一次性使用后标记 `used_at` |
+| 存储 | MySQL 表（写入频率极低，无需 Redis） |
+| 清理 | 健康检查时附带清理 `expires_at < NOW()` 的记录 |
+| 改动 | `backup.ts` 和 `export.ts` 的下载逻辑改为先获取凭证再用凭证下载 |
+
+#### S5：Refresh Token 机制
+
+| 项目 | 方案 |
+|------|------|
+| 架构 | 双 Token 机制：Access Token（2h）+ Refresh Token（30d） |
+| 存储 | `refresh_tokens` 表，仅存储 SHA-256 hash（不存明文） |
+| 轮换 | 每次刷新后旧 Refresh Token 立即失效（`revoked_at`），返回新 Token |
+| 前端适配 | `request.ts` 401 → 尝试 refresh → 成功则重试原请求 → refresh 也失败则清 token 跳登录 |
+| 安全 | 修改密码时撤销所有 Refresh Token；单用户最多 5 个有效 Refresh Token |
+| 优势 | 保持现有 HMAC-SHA256 签名方式不变，仅缩短 Access Token 有效期 |
+
+#### S6：Admin 硬删除 → 软删除 + 二次确认
+
+| 项目 | 方案 |
+|------|------|
+| DB 变更 | `users` 表新增 `deleted_at DATETIME DEFAULT NULL` + 索引 |
+| 删除操作 | `UPDATE users SET deleted_at = NOW() WHERE id = ?` |
+| 恢复接口 | `POST /api/admin/users/:id/restore` → `SET deleted_at = NULL` |
+| 全局过滤 | 所有涉及 `users` 表的查询增加 `WHERE deleted_at IS NULL` |
+| 前端确认 | 管理页点击删除 → 弹窗二次确认 → 调用软删除接口 |
+
+#### S7：DB 连接移除默认凭据
+
+| 项目 | 方案 |
+|------|------|
+| 修复 | 移除所有 `|| 'localhost'`、`|| 'xiaocai'`、`|| 'xiaocai123'` fallback |
+| 启动校验 | 遍历必需环境变量，缺失任一即 `process.exit(1)` |
+
+### 1.2 通用组件抽取方案
+
+#### ManageList 组件
+
+```
+client/src/components/ManageList/ManageList.vue
+
+Props:
+  - items: T[]               // 列表数据
+  - displayField: string      // 显示字段名
+  - colorField?: string       // 颜色字段名（标签用）
+  - iconField?: string        // 图标字段名（分类用）
+  - showDrag?: boolean        // 是否显示拖拽排序
+  - showEdit?: boolean        // 是否显示编辑按钮
+  - showDelete?: boolean      // 是否显示删除按钮
+  - emptyText?: string        // 空状态文案
+
+Emits:
+  - add()
+  - edit(item: T)
+  - delete(item: T)
+  - sort(ids: number[])
+
+Slots:
+  - item-icon="{ item }"      // 自定义图标区域（分类用 CategoryIcon）
+  - item-badge="{ item }"     // 自定义标签区域
+```
+
+#### ColorPicker 组件
+
+```
+client/src/components/ColorPicker/ColorPicker.vue
+
+Props:
+  - modelValue: string        // 当前选中颜色
+  - colors?: string[]         // 可选颜色列表（默认 8 色）
+
+Emits:
+  - update:modelValue(color: string)
+```
+
+#### EditModal 组件
+
+```
+client/src/components/EditModal/EditModal.vue
+
+Props:
+  - visible: boolean
+  - title: string
+  - fields: EditField[]       // 动态字段配置
+  - modelValue: Record<string, any>
+
+Emits:
+  - update:visible(val: boolean)
+  - confirm(data: Record<string, any>)
+
+interface EditField {
+  key: string
+  label: string
+  type: 'text' | 'color'
+  placeholder?: string
+  maxlength?: number
+}
+```
+
+### 1.3 乐观更新实现模式
+
+```
+模式：先写本地 state，再异步调接口，失败则回滚
+
+async function addCategory(data) {
+  // 1. 生成临时 ID（负数，避免与真实 ID 冲突）
+  const tempId = -Date.now()
+  const optimisticItem = { id: tempId, ...data }
+
+  // 2. 立即更新本地 state
+  categories.value.push(optimisticItem)
+
+  try {
+    // 3. 调用 API
+    const result = await api.createCategory(data)
+
+    // 4. 用真实 ID 替换临时 ID
+    const idx = categories.value.findIndex(c => c.id === tempId)
+    if (idx !== -1) categories.value[idx].id = result.id
+  } catch (err) {
+    // 5. 回滚：移除临时项
+    categories.value = categories.value.filter(c => c.id !== tempId)
+    uni.showToast({ title: '操作失败', icon: 'none' })
+  }
+}
+
+适用范围：
+  ✅ 新增分类/标签、编辑分类/标签、拖拽排序
+  ❌ 删除操作仍等接口确认（防误删）
+```
+
+### 1.4 Refresh Token 实现方案
+
+```
+┌──────────┐     POST /auth/login      ┌──────────┐
+│  Client  │ ──────────────────────────>│  Server  │
+│          │<──────────────────────────│          │
+│          │  { accessToken, refreshToken }       │
+│          │                            │          │
+│          │  GET /api/xxx              │          │
+│          │  Header: Bearer <accessToken>       │
+│          │ ──────────────────────────>│          │
+│          │<──────────────────────────│          │
+│          │  200 OK                    │          │
+│          │                            │          │
+│          │  GET /api/xxx (token 过期)  │          │
+│          │ ──────────────────────────>│          │
+│          │<──────────────────────────│          │
+│          │  401 { code: 40101 }       │          │
+│          │                            │          │
+│          │  POST /auth/refresh        │          │
+│          │  { refreshToken }          │          │
+│          │ ──────────────────────────>│          │
+│          │<──────────────────────────│          │
+│          │  { accessToken, refreshToken }       │
+│          │                            │          │
+│          │  重试原请求                 │          │
+│          │ ──────────────────────────>│          │
+└──────────┘                            └──────────┘
+```
+
+**后端关键实现**：
+- `auth.ts` 登录成功时：生成 Access Token（2h）+ Refresh Token（randomBytes(32)），存 hash 到 `refresh_tokens` 表
+- 新增 `POST /auth/refresh`：验证 Refresh Token hash → 撤销旧 Token → 生成新双 Token
+- `middleware/auth.ts`：Access Token 过期返回 `40101`（区别于无效 Token 的 `40100`）
+
+**前端关键实现**：
+- `request.ts`：收到 `40101` → 调用 `/auth/refresh` → 成功则重试 → 失败则清 token 跳登录
+- 存储：`xc:accessToken` + `xc:refreshToken` 分开存储
+- 并发请求时只触发一次 refresh，其他请求排队等待
+
+### 1.5 软删除方案
+
+```
+影响范围：
+  - users 表：新增 deleted_at 字段
+  - 所有 JOIN users 的查询：增加 deleted_at IS NULL 过滤
+  - admin.ts：DELETE → UPDATE SET deleted_at
+  - 新增恢复接口
+  - 登录验证：检查 deleted_at IS NULL
+
+具体改动位置：
+  1. schema.sql / migrate.sql：ALTER TABLE
+  2. auth.ts 登录：WHERE openid = ? AND deleted_at IS NULL
+  3. admin.ts 用户列表：WHERE deleted_at IS NULL（或增加"已禁用"筛选）
+  4. transaction.ts 列表查询：JOIN users 时增加 u.deleted_at IS NULL
+  5. 群组统计/成员列表：增加 deleted_at 过滤
+```
+
+### 1.6 iconfont 迁移方案
+
+```
+当前状态：Icon.vue 使用 PNG 图片映射
+迁移方案：
+  1. 在 iconfont.cn 创建项目，上传 SVG 图标
+  2. 生成字体文件（ttf），放入 client/src/static/iconfont/
+  3. 新建 client/src/styles/iconfont.scss，@font-face 声明
+  4. Icon.vue 改为 <text class="iconfont icon-xxx" /> 方式渲染
+  5. 保留 name prop 接口不变，内部映射改为 class 名
+  6. 额外图标（如 lock）直接在 iconfont 项目中添加
+
+收益：
+  - 包体积减小（字体 < 20KB vs 多个 PNG）
+  - 支持动态颜色（color prop 直接生效）
+  - 新增图标只需上传 SVG，无需切图
+```
+
+### 1.7 离线队列方案
+
+```
+架构设计：
+
+1. 离线队列管理器（client/src/utils/offline.ts）
+   - pendingOps: 存储于 uni.setStorageSync('xc:pendingOps')
+   - 数据结构: Array<{ id: string, type: 'create', data: object, createdAt: number, status: 'pending' | 'failed' }>
+   - MVP 仅支持 create（新增记账）
+
+2. 网络状态监听
+   - App.vue onLaunch 中注册 uni.onNetworkStatusChange
+   - 网络恢复时自动调用 processPendingOps()
+
+3. 操作流程
+   - 有网络：正常调接口
+   - 无网络：
+     ├── 写入 pendingOps
+     ├── 本地 state 立即更新（乐观更新 + "待同步"标记）
+     └── Toast "已保存，将在网络恢复后同步"
+
+4. 同步流程
+   - 按时间顺序逐条执行
+   - 全部成功：清除队列 + toast "同步完成"
+   - 部分失败：标记失败项 + 保留在队列 + toast "N 条同步失败"
+
+5. 网络检测
+   - uni.getNetworkType() 获取当前网络状态
+   - 封装 isOnline(): boolean 工具函数
+```
+
+### 1.8 财务报告推送方案
+
+```
+架构设计：
+
+1. 定时任务（server/src/services/scheduler.ts）
+   - 使用 node-cron 实现
+   - 每周一 09:00：生成上周收支摘要 → 推送
+   - 每月 1 号 09:00：生成上月收支报告 → 推送
+
+2. 报告生成（server/src/services/report.ts）
+   - 查询指定时间范围的收支数据
+   - 生成摘要文本（总支出/收入、Top 分类、日均消费等）
+
+3. 微信订阅消息（server/src/services/wechat-subscribe.ts）
+   - 调用微信 subscribeMessage.send 接口
+   - 模板 ID 需在微信公众平台申请
+   - 用户需先授权订阅（一次性授权，每次推送需用户主动触发授权）
+
+4. 降级策略
+   - 优先站内通知（现有 notifications 系统）
+   - 微信订阅消息作为增强项
+   - 如果模板审核不通过，仅保留站内通知
+
+5. 用户设置
+   - user_settings 表存储推送开关
+   - 客户端设置页增加"财务报告推送"开关
+```
+
+### 1.9 预算预警方案
+
+```
+架构设计：
+
+1. 双重检查策略
+   - 实时检查：记账后立即检查预算（精准、低开销）
+   - 每日全量扫描：凌晨定时扫描所有用户预算（覆盖周期记账等非手动场景）
+
+2. 预警等级
+   - 80%：站内通知（type: 'personal', is_urgent: false）
+   - 100%：站内通知 + 微信订阅消息
+   - 120%：站内紧急通知（is_urgent: true）+ 微信订阅消息
+
+3. 去重机制
+   - 同一用户同一月同一等级只推送一次
+   - budget_alerts 表记录已推送的预警（user_id + month + level → UNIQUE）
+
+4. 触发点
+   - transaction.ts POST 创建记账后 → 调用 checkBudgetAlert(userId, month)
+   - scheduler.ts 每日扫描 → 批量 checkBudgetAlert
+```
+
+### 1.10 测试框架选型
+
+| 层级 | 框架 | 理由 |
+|------|------|------|
+| 后端集成测试 | Jest + supertest | Express 生态标配；supertest 无需启动真实服务器；与 ts-jest 配合良好 |
+| 前端 Store 测试 | Vitest + @pinia/testing | Vitest 与 Vite 原生集成（Uni-app 基于 Vite）；@pinia/testing 提供 createTestingPinia() |
+| 工具函数测试 | Jest（后端）+ Vitest（前端） | 纯函数测试最简单，适合作为测试练手 |
+| API 契约测试 | Jest + ajv（JSON Schema） | 轻量级方案，不需要引入完整的契约测试框架 |
+
+---

+## 三、数据结构和接口
+
+### 3.1 新增/修改的数据库表结构
+
+#### 新增表
+
+```sql
+-- 一次性下载凭证表（S4）
+CREATE TABLE IF NOT EXISTS download_tokens (
+  id INT AUTO_INCREMENT PRIMARY KEY,
+  token VARCHAR(64) NOT NULL UNIQUE COMMENT '随机凭证',
+  user_id INT NOT NULL,
+  resource_type ENUM('backup', 'export') NOT NULL COMMENT '资源类型',
+  resource_id VARCHAR(100) DEFAULT '' COMMENT '资源标识（备份名等）',
+  expires_at DATETIME NOT NULL COMMENT '过期时间',
+  used_at DATETIME DEFAULT NULL COMMENT '使用时间（NULL=未使用）',
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  INDEX idx_token (token),
+  INDEX idx_expires (expires_at),
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+
+-- Refresh Token 表（S5）
+CREATE TABLE IF NOT EXISTS refresh_tokens (

+  user_id INT NOT NULL,
+  token_hash VARCHAR(64) NOT NULL COMMENT 'SHA-256(token)',
+  expires_at DATETIME NOT NULL COMMENT '过期时间',
+  revoked_at DATETIME DEFAULT NULL COMMENT '撤销时间（NULL=有效）',
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  INDEX idx_user (user_id),
+  INDEX idx_hash (token_hash),
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+
+-- 预算预警记录表（F-2，去重用）
+CREATE TABLE IF NOT EXISTS budget_alerts (
+  id INT AUTO_INCREMENT PRIMARY KEY,
+  user_id INT NOT NULL,
+  month VARCHAR(7) NOT NULL COMMENT '格式：2026-05',
+  level ENUM('80', '100', '120') NOT NULL COMMENT '预警等级',
+  group_id INT DEFAULT NULL COMMENT '群组ID（NULL=个人）',
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  UNIQUE KEY uk_user_month_level (user_id, month, level, group_id),
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+
+-- 用户设置表（F-1 报告推送开关等）
+CREATE TABLE IF NOT EXISTS user_settings (

+  updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
+```
+
+#### 修改表
+
+```sql
+-- users 表：新增软删除字段（S6）
+ALTER TABLE users ADD COLUMN deleted_at DATETIME DEFAULT NULL COMMENT '软删除时间（NULL=正常）';
+CREATE INDEX idx_users_deleted ON users(deleted_at);
+
+-- budgets 表：新增 group_id 支持（UX-4）
+ALTER TABLE budgets DROP INDEX uk_user_month;
+ALTER TABLE budgets ADD COLUMN group_id INT DEFAULT NULL COMMENT '群组ID（NULL=个人预算）';
+ALTER TABLE budgets ADD UNIQUE KEY uk_user_group_month (user_id, group_id, month);
+ALTER TABLE budgets ADD INDEX idx_group_month (group_id, month);
+```

+### 8.3 金额处理
+
+```
+- 所有金额以「分」为单位存储（INT 类型）
+- 前端展示使用 formatAmount() 转为 "¥ 1,234.56" 格式
+- 输入时以「元」为单位，提交前乘以 100 转为分
+- 金额校验：1 <= amount <= 999999999（分）
+```
+
+### 8.4 日期处理
+
+```
+- 数据库存储 DATE 类型（YYYY-MM-DD）
+- 月份参数格式：YYYY-MM（如 "2026-06"）
+- 时区统一：服务器 + 客户端均按 UTC+8 处理
+- getCurrentMonth() 前后端逻辑一致
+```
+
+### 8.5 软删除约定
+
+```
+- users 表使用 deleted_at 字段标记软删除
+- 所有查询 users 表的 SQL 必须增加 WHERE deleted_at IS NULL
+- 登录时检查 deleted_at IS NULL
+- 群组成员查询需过滤已删除用户
+- 已删除用户在群组统计中标注"已注销用户"
+```
+
+### 8.6 乐观更新约定
+
+```
+- 新增/编辑操作：先更新本地 state → 再调 API → 失败回滚 + toast
+- 删除操作：仍等 API 确认后再移除（防误删）
+- 排序操作：全量回滚（排序是完整 ID 数组操作）
+- 临时 ID：使用负数时间戳（-Date.now()），API 成功后替换为真实 ID
+```
+
+### 8.7 前端缓存约定
+
+```
+- 低频变更数据（分类/标签）：5 分钟缓存，onShow 判断是否需要刷新
+- 未读计数：30 秒缓存
+- 缓存失效：手动操作（新增/编辑/删除）后立即清除对应缓存
+- 下拉刷新：强制清除缓存并重新请求
+```
+
+### 8.8 组件命名约定
+
+```
+- 组件目录：client/src/components/ComponentName/ComponentName.vue
+- Store 命名：use{Name}Store
+- API 模块：client/src/api/{name}.ts
+- 页面目录：client/src/pages/{name}/index.vue
+```

+## 九、待明确事项
+
+| # | 问题 | 影响范围 | 当前假设 | 风险 |
+|---|------|----------|----------|------|
+| Q1 | Refresh Token 存储方式 | S5 | 存 MySQL `refresh_tokens` 表；短中期可行，高并发时迁移 Redis | 当前写入频率极低，MySQL 足够 |
+| Q2 | 软删除级联范围 | S6 | 仅软删除用户账号，交易记录保留但通过 `deleted_at IS NULL` 过滤 | 保留交易可能影响群组统计，需标注"已注销用户" |
+| Q3 | 删除撤销批量上限 | UX-1 | 上限 5 条（Snackbar 最多显示"已删除 5 条记录"），超过直接删除 | 5 条覆盖绝大多数场景 |
+| Q4 | 离线记账冲突策略 | UX-6 | MVP 仅支持离线新增（不涉及修改/删除），新增使用服务端生成 ID，不存在主键冲突 | 如需离线编辑需引入版本号机制 |
+| Q5 | 微信订阅消息模板审核 | F-1 | 优先站内通知，微信订阅消息作为增强项；需提前申请模板审核 | 微信审核可能被拒，需准备备选方案 |
+| Q6 | 预算预警检查时机 | F-2 | 双重策略：记账后实时检查 + 每日凌晨全量扫描 | 仅实时检查可能遗漏周期记账触发的超支 |
+| Q7 | 乐观更新回滚粒度 | Perf-1 | 排序操作全量回滚（语义清晰），新增/编辑单条回滚 | 全量回滚可能丢失已做的其他排序操作 |
+| Q8 | 测试环境数据隔离 | T-1 | 独立测试数据库（.env.test），CI 用 GitHub Actions service container | 本地需额外配置测试数据库 |
+| Q9 | budgets 表 group_id 迁移 | UX-4 | 现有数据 group_id 默认 NULL（个人预算），UNIQUE KEY 从 (user_id, month) 改为 (user_id, group_id, month) | 迁移需确保不破坏现有预算数据 |
+| Q10 | iconfont 图标清单 | C8 | 需从现有 Icon.vue 的 PNG 映射中提取完整图标列表，并在 iconfont.cn 重新制作 | 部分图标可能无现成 SVG，需设计师配合 |

+
+### P3 — 健康检查
+
+> As a 管理员, I want 在管理页面看到后端服务运行状态, so that 我能第一时间发现服务异常。
+
+### P3 — 交易标签系统
+
+> As a 用户, I want 给交易添加标签（如"出差""聚餐"）, so that 我可以按标签筛选和统计关联交易。
+>
+> As a 用户, I want 按标签筛选交易列表和查看标签维度的统计, so that 我可以追踪特定场景的收支。

+
+---
+
+## 五、待确认问题
+
+| # | 问题 | 影响范围 | 建议 |
+|---|------|----------|------|
+| Q1 | 分类拖拽排序是否需要动画反馈？拖拽手柄位置（左侧还是右侧）？ | P0-1 | 建议左侧手柄 + 长按触发，符合主流交互习惯 |
+| Q2 | 用户反馈列表是否需要通知推送？当管理员回复后用户是否收到微信服务通知？ | P1-1 | 后端已有通知逻辑，但微信订阅消息需用户主动订阅，建议先做页面内展示，通知作为后续增强 |
+| Q3 | 备份文件的下载鉴权方式？URL 是否需要时效性签名？ | P1-2 | 建议使用临时签名 URL（有效期 1 小时），避免备份文件被猜测 URL 直接访问 |
+| Q4 | 统计年度视图的趋势图粒度：按月汇总还是按季汇总？ | P2-1 | 建议按月汇总（12 个点），季度可通过后续分组实现 |
+| Q5 | 数据导入的 JSON 格式规范？是否需要支持其他记账 App 的导出格式？ | P2-2 | 建议先定义小菜记账自有 JSON 格式，提供模板下载；其他 App 格式兼容作为远期需求 |
+| Q6 | 服务端导出的文件存储方式：内存生成直接流式返回 vs 先写文件再下载？ | P2-3 | 建议 < 1 万条内存流式返回，≥ 1 万条先写临时文件再下载，避免内存溢出 |
+| Q7 | 交易标签上限：每笔交易最多关联几个标签？每个用户最多创建多少个标签？ | P3-2~4 | 建议每笔交易最多 5 个标签，每用户最多 20 个标签，后续可调整 |
+| Q8 | 标签与分类的关系：标签是否可以跨分类？同一标签能否同时用于支出和收入？ | P3-2~4 | 建议标签不区分收支类型，跨分类使用，这是标签区别于分类的核心价值 |

+
+---
+
+## 四、安全修复方案
+
+### S1：.env 凭据泄露修复
+
+**当前状态**：`.env` 已在 `.gitignore` 中，但文件内容已在历史提交中暴露，包含数据库地址 `115.120.243.74`、密码 `dnjwYbpMdmASCxfH`、微信 AppID/Secret。
+
+**修复步骤**：
+
+1. **立即轮换所有已泄露凭据**：
+   - MySQL: 修改 `xiaocai_test` 用户密码
+   - 微信: 在微信公众平台重置 AppSecret
+   - TOKEN_SECRET: 生成新的强随机密钥（`openssl rand -hex 32`）
+2. **清除 Git 历史**：
+   ```bash
+   # 使用 git-filter-repo（推荐，比 BFG 更安全）
+   pip install git-filter-repo
+   git filter-repo --path server/.env --invert-paths
+   git filter-repo --blob-callback 'blob.data = blob.data.replace(b"dnjwYbpMdmASCxfH", b"REDACTED")'
+   ```
+3. **强制推送并通知协作者**：
+   ```bash
+   git push origin --force --all
+   ```
+4. **验证 `.gitignore` 生效**：
+   ```bash
+   git check-ignore server/.env  # 应输出 server/.env
+   ```
+5. **添加 pre-commit hook 防止再次提交**：
+   ```bash
+   # .githooks/pre-commit
+   if git diff --cached --name-only | grep -q '\.env'; then
+     echo "ERROR: .env files must not be committed"
+     exit 1
+   fi
+   ```
+
+**回滚方案**：Git 历史重写前创建完整备份 `git clone --mirror`。
+
+### S2：logs.ts SQL 拼接修复
+
+**当前状态**：`server/routes/logs.ts:160-168` 使用模板字符串拼接 LIMIT/OFFSET：
+
+```typescript
+// ❌ 当前代码
+LIMIT ${pSize} OFFSET ${offset}
+```
+
+**修复方案**：
+
+```typescript
+// ✅ 方案 A：参数化查询（推荐）
+const safeLimit = Math.min(Math.max(parseInt(String(pSize)) || 10, 1), 100)
+const safeOffset = Math.max(parseInt(String(offset)) || 0, 0)
+const [rows] = await pool.query(
+  `SELECT t.*, u.nickname
+   FROM track_events t
+   LEFT JOIN users u ON t.user_id = u.id
+   WHERE ${where}
+   ORDER BY t.created_at DESC
+   LIMIT ? OFFSET ?`,
+  [...params, safeLimit, safeOffset]
+)
+```
+
+**关键点**：`LIMIT`/`OFFSET` 的值必须先 `parseInt` + 范围校验，防止非整数或超大值；`pool.query` 支持 `?` 占位符用于整数参数（与 `pool.execute` 的 prepared statement 不同）。
+
+### S3：TOKEN_SECRET 弱默认值 + 命名不一致
+
+**当前状态**：
+- `auth.ts` / `middleware/auth.ts`：`process.env.TOKEN_SECRET || 'xiaocai-token-secret-change-in-production'`
+- `backup.ts`：`process.env.JWT_SECRET || 'xiaocai-secret'`（命名不一致 + 弱默认值）
+- `.env` 中：`TOKEN_SECRET=xiaocai-prod-secret-2026-change-me`（弱密钥）
+
+**修复方案**：
+
+1. **统一命名为 `TOKEN_SECRET`**：
+   - `backup.ts` 中 `JWT_SECRET` → `TOKEN_SECRET`
+   - 删除 `const JWT_SECRET = ...` 声明，改为从 `middleware/auth.ts` 导出或统一读取 `process.env.TOKEN_SECRET`
+
+2. **移除所有 fallback 默认值，强制要求环境变量**：
+   ```typescript
+   // server/src/config/token.ts（新增）
+   export const TOKEN_SECRET = process.env.TOKEN_SECRET
+   if (!TOKEN_SECRET || TOKEN_SECRET.length < 32) {
+     console.error('[Security] TOKEN_SECRET must be set and at least 32 characters')
+     process.exit(1)
+   }
+   ```
+
+3. **生成强密钥**：
+   ```bash
+   # 在服务器上生成并写入 .env
+   echo "TOKEN_SECRET=$(openssl rand -hex 32)" >> server/.env
+   ```
+
+4. **所有引用处改为**：
+   ```typescript
+   import { TOKEN_SECRET } from '../config/token'
+   ```
+
+### S4：Export/Backup URL 短期一次性下载凭证
+
+**当前状态**：
+- `backup.ts`：下载链接使用 HMAC 签名的 `backupId:timestamp:hmac` 格式 token，通过 query string 传递
+- `export.ts`：导出接口支持 query string 传 token 兼容
+
+**问题**：虽然已有 HMAC 签名，但无过期时间校验（backup 有 timestamp 但未校验时效），且 token 可重复使用。
+
+**修复方案**：
+
+1. **新增 `download_tokens` 表**：
+   ```sql
+   CREATE TABLE download_tokens (
+     id INT AUTO_INCREMENT PRIMARY KEY,
+     token VARCHAR(64) NOT NULL UNIQUE,
+     user_id INT NOT NULL,
+     resource_type ENUM('backup', 'export') NOT NULL,
+     resource_id VARCHAR(100),
+     expires_at DATETIME NOT NULL,
+     used_at DATETIME DEFAULT NULL,
+     created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+     INDEX idx_token (token),
+     INDEX idx_expires (expires_at)
+   );
+   ```
+
+2. **生成下载凭证**：
+   ```typescript
+   // 有效期 5 分钟
+   const token = randomBytes(32).toString('hex')
+   await pool.query(
+     'INSERT INTO download_tokens (token, user_id, resource_type, resource_id, expires_at) VALUES (?, ?, ?, ?, DATE_ADD(NOW(), INTERVAL 5 MINUTE))',
+     [token, userId, 'backup', backupId]
+   )
+   ```
+
+3. **验证下载凭证**：
+   ```typescript
+   const [rows] = await pool.query(
+     'SELECT * FROM download_tokens WHERE token = ? AND user_id = ? AND expires_at > NOW() AND used_at IS NULL',
+     [token, userId]
+   )
+   if (!rows.length) return res.status(403).json({ code: 40300, message: '下载凭证无效或已过期' })
+   // 标记为已使用
+   await pool.query('UPDATE download_tokens SET used_at = NOW() WHERE id = ?', [rows[0].id])
+   ```
+
+4. **定期清理过期 token**：在 health check 或定时任务中清理 `expires_at < NOW()` 的记录。
+
+### S5：Refresh Token 机制
+
+**当前状态**：单 Token 机制，HMAC-SHA256 签名，30 天过期，无轮换。
+
+**修复方案**：
+
+1. **双 Token 机制**：
+   - Access Token：有效期 2 小时，用于 API 调用
+   - Refresh Token：有效期 30 天，仅用于刷新 Access Token
+
+2. **新增 `refresh_tokens` 表**：
+   ```sql
+   CREATE TABLE refresh_tokens (
+     id INT AUTO_INCREMENT PRIMARY KEY,
+     user_id INT NOT NULL,
+     token_hash VARCHAR(64) NOT NULL,
+     expires_at DATETIME NOT NULL,
+     revoked_at DATETIME DEFAULT NULL,
+     created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+     INDEX idx_user (user_id),
+     INDEX idx_hash (token_hash)
+   );
+   ```
+
+3. **认证流程**：
+   - 登录：返回 `accessToken` + `refreshToken`
+   - API 调用：Header 带 `Authorization: Bearer <accessToken>`
+   - Token 过期（401）：前端用 `refreshToken` 调用 `/auth/refresh` 获取新 `accessToken` + 新 `refreshToken`（旧 refresh token 失效）
+   - Refresh Token 也过期：需重新登录
+
+4. **前端适配**（`client/src/utils/request.ts`）：
+   - 现有 401 重登录机制改为 401 → refresh → 重试
+   - refresh 也失败（401）→ 清除本地 token → 跳转登录
+
+5. **安全措施**：
+   - Refresh Token 存储 hash 值（SHA-256），不存明文
+   - 每个 Refresh Token 仅使用一次（用后旧 token 失效）
+   - 用户修改密码时撤销所有 Refresh Token
+
+### S6：Admin 硬删除 → 软删除 + 二次确认
+
+**当前状态**：`admin.ts:170` 直接 `DELETE FROM users WHERE id = ?`，无二次确认。
+
+**修复方案**：
+
+1. **DB Schema 变更**：
+   ```sql
+   ALTER TABLE users ADD COLUMN deleted_at DATETIME DEFAULT NULL;
+   CREATE INDEX idx_users_deleted ON users(deleted_at);
+   ```
+
+2. **后端修改**：
+   ```typescript
+   // 软删除
+   router.delete('/users/:id', async (req, res) => {
+     await pool.query('UPDATE users SET deleted_at = NOW() WHERE id = ?', [req.params.id])
+     res.json({ code: 0, data: { message: '用户已禁用' } })
+   })
+
+   // 恢复
+   router.post('/users/:id/restore', async (req, res) => {
+     await pool.query('UPDATE users SET deleted_at = NULL WHERE id = ?', [req.params.id])
+     res.json({ code: 0, data: { message: '用户已恢复' } })
+   })
+   ```
+
+3. **全局查询过滤**：在 `auth.ts` 登录时检查 `deleted_at IS NULL`；其他查询同理。
+
+4. **前端二次确认**：
+   ```
+   管理员点击"删除用户" → 弹出确认弹窗：
+   "确定要禁用用户「{nickname}」吗？该操作将冻结该用户的所有数据，但不会删除记录。"
+   [取消] [确认禁用]
+   ```
+
+### S7：DB 连接移除默认凭据
+
+**当前状态**：`connection.ts` 中 `password: process.env.DB_PASSWORD || 'xiaocai123'` 等硬编码默认值。
+
+**修复方案**：
+
+```typescript
+// ✅ 修复后
+const required = ['DB_HOST', 'DB_USER', 'DB_PASSWORD', 'DB_NAME'] as const
+for (const key of required) {
+  if (!process.env[key]) {
+    console.error(`[DB] Missing required environment variable: ${key}`)
+    process.exit(1)
+  }
+}
+
+const pool = mysql.createPool({
+  host: process.env.DB_HOST!,
+  user: process.env.DB_USER!,
+  password: process.env.DB_PASSWORD!,
+  database: process.env.DB_NAME!,
+  waitForConnections: true,
+  connectionLimit: 10,
+  queueLimit: 0,
+})
+```
+
+---
+
+## 五、UI 交互说明
+
+### UX-1：删除撤销
+
+```
+交互流程：
+
+1. 用户在账单列表左滑删除某条记录
+2. 记录从列表中移除（动画：向左滑出）
+3. 底部弹出 Snackbar：
+   ┌───────────────────────────────────────────┐
+   │ 🗑 已删除 1 条记录          [撤销]        │
+   └───────────────────────────────────────────┘
+   - 背景色: $surface (#FFFFFF)
+   - 文字色: $text-sec (#8B7E7E)
+   - "撤销"按钮: $primary (#FF8C69) + 500 字重
+   - 自动消失时间: 3 秒
+   - 从底部上滑动画: 200ms ease-out
+4. 3 秒内点击"撤销"：
+   - 记录重新插入列表原位置（动画：从左侧滑入）
+   - 不调用后端删除接口
+   - Snackbar 消失
+5. 3 秒超时未操作：
+   - Snackbar 下滑消失
+   - 调用后端 DELETE /transactions/:id
+   - 如果接口失败，记录恢复到列表 + 错误提示
+
+实现要点：
+- 删除操作先只移除前端列表项，不立即调接口
+- 使用 pendingDelete Map 存储待删除记录（id → 原始数据 + 原位置索引）
+- 多次快速删除时 Snackbar 累加计数："已删除 N 条记录"
+- 撤销时按 LIFO 顺序恢复
+```
+
+### UX-2：群组只读标记
+
+```
+交互设计：
+
+1. TransactionItem 组件变更：
+   - 新增 props: `isReadOnly: boolean`
+   - 非本人记录（transaction.user_id !== currentUserId）：
+     ├── 右上角显示小锁图标（Lucide Lock, 16rpx, $text-sec 颜色）
+     ├── 左滑不显示删除按钮
+     └── 整体透明度降为 0.85（区分视觉层级）
+
+2. 点击交互：
+   - 本人记录：点击 → 编辑页面（现有行为）
+   - 非本人记录：点击 → 查看页面（只读模式）
+     ├── 页面布局与编辑页相同
+     ├── 所有输入框/选择器为 disabled 态
+     ├── 金额/分类/标签仅展示不可修改
+     ├── 底部无"保存"按钮
+     └── 顶部标题显示"查看记录"
+
+3. 群组视图下的记账按钮：
+   - 仍然可以新增自己的记录
+   - 新增记录自动归属当前用户
+```
+
+### UX-3：waitForReady 超时处理
+
+```
+交互流程：
+
+1. 页面 onMounted 调用 await waitForReady()
+2. 如果 8 秒内未就绪：
+   - waitForReady() reject（而非当前 resolve）
+   - 页面 catch 中显示全屏错误状态：
+     ┌─────────────────────────┐
+     │                         │
+     │      ⚠️ 网络连接异常     │
+     │   请检查网络后点击重试   │
+     │                         │
+     │      [重新加载]         │
+     │                         │
+     └─────────────────────────┘
+   - "重新加载"按钮点击后重新执行 waitForReady() + loadData()
+   - 不再静默以未登录状态加载数据
+```
+
+### UX-4：预算 group_id 支持
+
+```
+交互设计：
+
+1. 预算页面（budget/index.vue）变更：
+   - 个人视图：显示"我的月度预算"（现有行为不变）
+   - 群组视图：显示两个卡片：
+     ├── 群组总预算卡片：所有成员预算之和 + 群组总支出
+     │   └── "群组总预算 ¥ 8,000.00"
+     └── 我的预算卡片：当前用户个人预算 + 个人支出
+         └── "我的预算 ¥ 3,000.00"
+
+2. 设置预算弹窗变更：
+   - 个人视图：设置个人月度预算
+   - 群组视图：设置"我在群组中的月度预算"
+   - 弹窗标题根据视图切换
+
+3. 预算进度条变更：
+   - 个人视图：支出/预算（现有）
+   - 群组视图：
+     ├── 总进度条：群组总支出 / 群组总预算
+     └── 我的进度条：我的支出 / 我的预算（子进度条样式）
+```
+
+### UX-5：下拉刷新统一
+
+```
+实现规范：
+
+1. pages.json 全局配置：
+   "globalStyle": {
+     "enablePullDownRefresh": true
+   }
+
+2. 所有数据页面统一模式：
+   onPullDownRefresh(async () => {
+     await loadData()
+     uni.stopPullDownRefresh()
+   })
+
+3. 需要启用下拉刷新的页面：
+   - 首页 index
+   - 账单页 bills
+   - 统计页 stats
+   - 通知中心 notifications
+   - 群组管理 group-manage
+   - 标签管理 tag-manage
+
+4. 不启用下拉刷新的页面：
+   - 表单页（add, profile-edit, budget）
+   - 设置页
+```
+
+### UX-6：离线支持
+
+```
+架构设计：
+
+1. 操作队列（localStorage）：
+   - Key: `xc:pendingOps`
+   - 数据结构：
+     [
+       { id: 'uuid', type: 'create', data: {...}, createdAt: timestamp, status: 'pending' },
+       { id: 'uuid', type: 'update', data: {...}, createdAt: timestamp, status: 'pending' }
+     ]
+
+2. 网络状态监听：
+   onMounted(() => {
+     uni.onNetworkStatusChange(({ isConnected }) => {
+       if (isConnected) processPendingOps()
+     })
+   })
+
+3. 操作执行流程：
+   - 有网络：正常调接口
+   - 无网络：
+     ├── 写入操作队列
+     ├── 本地 state 立即更新（乐观更新）
+     ├── 记录标记为"待同步"状态（右下角小图标）
+     └── Toast："已保存，将在网络恢复后同步"
+
+4. 同步流程（processPendingOps）：
+   - 按时间顺序逐条执行
+   - 全部成功：清除队列 + toast "同步完成"
+   - 部分失败：标记失败项 + toast "N 条同步失败" + 保留在队列中重试
+
+5. 限制范围：
+   - MVP 阶段仅支持"新增记账"离线操作
+   - 编辑/删除等操作离线时禁用（提示"请连接网络后操作"）
+```
+
+### UX-7：Loading 态统一
+
+```
+规范：
+
+1. 页面级加载：使用 Skeleton 骨架屏组件
+   - 首次加载 onMounted 时显示
+   - 下拉刷新不显示骨架屏（数据已存在）
+
+2. 操作级加载：按钮/操作区域 loading 态
+   - 按钮点击后 disabled + 显示 spinner
+   - 防止重复提交（debounce 300ms 或 loading ref 守卫）
+
+3. 全局 loading：
+   - 页面切换时的导航栏 loading（uni.showNavigationBarLoading）
+   - 长时间操作（导出/备份）使用全屏 loading + 进度提示
+
+4. 空状态：
+   - 数据为空时显示空状态插画 + 引导文案
+   - 与加载中状态明确区分（不是空白页）
+```

+
+## 六、性能优化方案
+
+### Perf-1：分类/标签乐观更新
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 新增/编辑/排序分类后，等待接口返回才更新列表，用户感知延迟 200-500ms |
+| 优化策略 | 先更新本地 Pinia state，再异步调接口；接口失败时回滚 state + toast 提示 |
+| 实现方式 | Store 方法内部：先 `state.items.push(newItem)` → `await api.create()` → 失败则 `state.items.pop()` + `toast('操作失败')` |
+| 预期效果 | 操作感知延迟从 200-500ms 降至 < 16ms（一帧） |
+| 适用范围 | 新增分类/标签、编辑分类/标签、拖拽排序；删除操作仍等接口确认（防误删） |
+
+### Perf-2：groupStore 并行加载
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | `refreshAll()` 中 `fetchCategories()` → `fetchTags()` → `fetchTransactions()` 串行执行，总耗时 = 3 次请求之和 |
+| 优化策略 | 无依赖的请求改为 `Promise.all()` 并行执行 |
+| 实现方式 | `await Promise.all([fetchCategories(), fetchTags()]); await fetchTransactions()`（transactions 依赖 categories 的映射） |
+| 预期效果 | 并行部分耗时 = max(单次请求)，总体减少 40-60% |
+
+### Perf-3：Stats 聚合接口
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 统计页加载时串行调用 `/stats/overview` + `/stats/category` + `/stats/trend`，3 次 HTTP 往返 |
+| 优化策略 | 合并为单一 `/stats/dashboard` 接口，后端并行查询后一次性返回 |
+| 实现方式 | 后端新路由中 `Promise.all([queryOverview, queryCategory, queryTrend])` → 返回 `{ overview, category, trend }` |
+| 预期效果 | 3 次 HTTP 往返 → 1 次；减少约 200ms 网络开销 |
+
+### Perf-4：Track 批量 INSERT
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 前端一次页面访问可能触发多条埋点，每条单独 INSERT，N 条 = N 次数据库写入 |
+| 优化策略 | 前端批量发送，后端使用 `INSERT INTO ... VALUES (?), (?), (?)` 批量写入 |
+| 实现方式 | 前端 `tracker.ts` 攒批（500ms 或 10 条），批量 POST；后端 `track.ts` 接收数组后构建批量 INSERT |
+| 预期效果 | 10 条埋点从 10 次 INSERT 降至 1 次，减少数据库连接开销 90% |
+
+### Perf-5：Admin N+1 查询
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 用户列表查询后，循环每个用户查询其交易数/群组数等信息，N 个用户 = 1 + N 次查询 |
+| 优化策略 | 使用 LEFT JOIN + GROUP BY 在一次查询中获取所有关联数据 |
+| 实现方式 | `SELECT u.*, COUNT(DISTINCT t.id) as tx_count, COUNT(DISTINCT gm.group_id) as group_count FROM users u LEFT JOIN transactions t ON ... LEFT JOIN group_members gm ON ... GROUP BY u.id` |
+| 预期效果 | 1+N 次查询 → 1 次查询；列表加载从 O(n) 降至 O(1) |
+
+### Perf-6：前端数据缓存
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 分类、标签等低频变更数据每次 `onShow` 都重新请求 |
+| 优化策略 | 增加 `lastFetchTime` 标记，5 分钟内 `onShow` 跳过请求 |
+| 实现方式 | Store 中增加 `lastFetchTime: Ref<number>`，`fetch()` 前判断 `Date.now() - lastFetchTime.value < 5 * 60 * 1000` 则跳过 |
+| 预期效果 | 页面切换时减少 60-80% 的冗余请求 |
+
+### Perf-7：未读计数缓存
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 每次进入"我的"页面或 `onShow` 都请求未读通知计数 |
+| 优化策略 | 计数结果缓存 30 秒；读取通知后主动清零缓存 |
+| 实现方式 | `unreadCount` 请求后记录 `lastFetchTime`，30s 内直接返回缓存值；`markAllRead()` 后 `unreadCount = 0` + 清缓存 |
+| 预期效果 | 频繁切换页面时减少通知计数请求 80%+ |
+
+### Perf-8：Logs 流式读取（P2）
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 管理后台查看日志时全量加载到内存 |
+| 优化策略 | 使用 Node.js stream 分批返回 |
+| 实现方式 | `fs.createReadStream(logPath).pipe(res)` 或数据库 `queryStream()` |
+| 预期效果 | 内存占用从 O(n) 降至 O(buffer_size) |
+
+### Perf-9：ChartWrapper 延迟渲染（P2）
+
+| 项目 | 说明 |
+|------|------|
+| 当前问题 | 统计页所有图表同时渲染，低端设备卡顿 |
+| 优化策略 | 使用 IntersectionObserver，图表进入可视区域后才渲染 |
+| 实现方式 | ChartWrapper 组件内监听可视状态，不可见时显示占位（固定高度 div） |
+| 预期效果 | 首屏渲染时间减少 30-50% |
+
+---
+
+## 七、测试体系建设计划
+
+> 目标：从零覆盖到核心路径有保障，分 4 阶段逐步建设
+
+### 阶段一：后端路由集成测试（P1，预计 2 周）
+
+**范围**：核心 CRUD 路由的集成测试
+
+**技术栈**：Jest + supertest + 测试数据库
+
+**覆盖清单**：
+
+| 模块 | 测试用例 | 优先级 |
+|------|----------|--------|
+| auth | 登录成功/失败、Token 生成与验证、无效 Token 拒绝 | P0 |
+| transaction | CRUD、group_id 过滤、分页、金额精度 | P0 |
+| category | CRUD、默认/自定义分类隔离、排序、迁移 | P1 |
+| budget | CRUD、月度预算、群组视图 | P1 |
+| stats | overview/category/trend 查询、period 参数校验 | P2 |
+
+**实现步骤**：
+
+1. 安装依赖：`npm i -D jest ts-jest supertest @types/supertest`
+2. 创建测试数据库配置：`.env.test` 指向独立测试库
+3. 编写 `tests/setup.ts`：每个测试套件前清空测试库 + seed
+4. 编写路由测试：使用 `supertest(app)` 发送请求，断言状态码 + 返回格式
+5. 配置 `npm test` 命令
+
+**验收标准**：核心路由测试覆盖率 ≥ 80%，`npm test` 全绿。
+
+### 阶段二：前端 Store 单元测试（P1，预计 1.5 周）
+
+**范围**：Pinia Store 的核心逻辑测试
+
+**技术栈**：Vitest + @pinia/testing
+
+**覆盖清单**：
+
+| Store | 测试用例 | 优先级 |
+|-------|----------|--------|
+| transaction | fetchList/fetchDetail/create/update/delete、乐观更新、删除撤销 | P0 |
+| category | fetchAll/create/update/sort/乐观更新 | P1 |
+| budget | fetch/set/群组视图 | P1 |
+| group | fetchGroups/switchToPersonal/leaveGroup（BUG-03 回归） | P0 |
+| user | login/logout/token 管理 | P1 |
+
+**实现步骤**：
+
+1. 安装依赖：`npm i -D vitest @pinia/testing @vue/test-utils`
+2. 创建 `vitest.config.ts`
+3. Mock API 调用：使用 `vi.mock('@/api/*')`
+4. 编写 Store 测试：使用 `createTestingPinia()`
+5. 配置 `npm run test:unit` 命令
+
+**验收标准**：Store 核心方法测试覆盖率 ≥ 70%。
+
+### 阶段三：API 契约测试（P2，预计 1 周）
+
+**范围**：确保前后端 API 接口格式一致
+
+**技术栈**：Jest + JSON Schema 验证
+
+**实现方式**：
+
+1. 定义 API 响应 Schema（`tests/schemas/`）：
+   ```typescript
+   // transaction-response.schema.ts
+   export const transactionListSchema = {
+     type: 'object',
+     required: ['code', 'data'],
+     properties: {
+       code: { const: 0 },
+       data: {
+         type: 'object',
+         required: ['list', 'total'],
+         properties: {
+           list: { type: 'array' },
+           total: { type: 'number' }
+         }
+       }
+     }
+   }
+   ```
+
+2. 集成测试中同时验证响应格式符合 Schema
+3. 前端 `request.ts` 添加开发模式响应校验
+
+**验收标准**：所有已定义 Schema 的接口响应 100% 符合契约。
+
+### 阶段四：工具函数单元测试（P2，预计 1 周）
+
+**范围**：前端 `utils/` 和后端 `utils/` 的纯函数测试
+
+**覆盖清单**：
+
+| 模块 | 测试用例 |
+|------|----------|
+| `format.ts` | `formatAmount`、`formatDate`（含跨年 BUG-02 回归）、`formatAmountRaw` |
+| `request.ts` | 401 重试队列、超时处理、请求参数格式 |
+| `app-ready.ts` | waitForReady 正常/超时场景 |
+| `backup.ts`（后端） | 备份文件生成、签名校验 |
+| `date.ts`（后端） | `getCurrentMonth`、`getMonthRange` |
+
+**验收标准**：工具函数测试覆盖率 ≥ 90%。
+
+---
+
+## 八、待确认问题
+
+| # | 问题 | 影响范围 | 建议方案 | 风险 |
+|---|------|----------|----------|------|
+| Q1 | Refresh Token 存储方式：数据库 vs Redis | S5 | 当前技术栈无 Redis，建议存 MySQL `refresh_tokens` 表；如果后续并发量增长，迁移到 Redis | MySQL 写入频率低，短中期可行 |
+| Q2 | 软删除的级联范围：是否需要同时软删除该用户的所有交易记录？ | S6 | 建议仅软删除用户账号（`deleted_at`），交易记录保留但通过 `deleted_at IS NULL` 过滤；历史数据完整性更重要 | 保留交易可能影响群组统计，需在群组视图中标注"已注销用户" |
+| Q3 | 删除撤销的批量操作上限：最多支持同时撤销几条？ | UX-1 | 建议上限 5 条（Snackbar 最多显示"已删除 5 条记录"）；超过 5 条时直接删除不走撤销流程 | 5 条覆盖绝大多数场景，过多会增加本地状态管理复杂度 |
+| Q4 | 离线记账的冲突策略：如果离线期间同一条记录被其他设备修改了怎么办？ | UX-6 | MVP 阶段仅支持离线新增（不涉及修改/删除），新增记录使用服务端生成的 ID，不存在主键冲突 | 如需支持离线编辑，需引入版本号或时间戳对比机制 |
+| Q5 | 财务报告推送的微信订阅消息模板审核：微信对金融类模板审核严格，是否需要用户额外授权？ | F-1 | 建议先实现站内通知（现有通知系统），微信订阅消息作为增强项；需提前申请微信模板消息审核 | 微信审核可能被拒，需准备备选方案（如短信或仅站内推送） |
+| Q6 | 预算预警的检查时机：仅在记账后检查 vs 定时全量扫描？ | F-2 | 建议双重策略：记账后实时检查（精准、低开销）+ 每日凌晨全量扫描（覆盖非记账场景如周期记账自动生成） | 仅实时检查可能遗漏周期记账触发的超支 |
+| Q7 | 乐观更新的回滚粒度：分类排序失败时，是回滚全部排序还是仅回滚失败项？ | Perf-1 | 建议回滚全部：排序是全量操作（传递完整 ID 数组），部分回滚语义不清晰；失败后恢复排序前快照 + toast | 全量回滚用户感知更一致，但可能丢失用户已做的其他排序操作 |
+| Q8 | 测试环境数据隔离：集成测试使用独立数据库还是 Docker 容器？ | T-1 | 建议独立测试数据库（`.env.test`），不用 Docker（减少 CI 复杂度）；CI 环境中用 GitHub Actions service container 启动 MySQL | 本地开发需额外配置测试数据库，但比 Docker 方案简单 |
+
+---
+
+## 九、迭代排期建议
+
+| 阶段 | 时间 | 内容 | 交付物 |
+|------|------|------|--------|
+| **Phase 0** | 第 1 周 | P0 安全修复（S1/S2/S3） | 凭据轮换完成、SQL 参数化、TOKEN_SECRET 强制 |
+| **Phase 1** | 第 2-3 周 | P1 安全（S4-S7）+ P1 代码质量（C1/C2/C4/C5/C7） | 双 Token 机制、软删除、代码去重 |
+| **Phase 2** | 第 4-5 周 | P1 性能（Perf-1~7）+ P1 UX（UX-1~4） | 乐观更新、聚合接口、删除撤销、群组只读 |
+| **Phase 3** | 第 6-7 周 | P1 测试（T-1）+ P1 新功能（F-1/F-2） | 集成测试覆盖、财务报告推送、预算预警 |
+| **Phase 4** | 第 8-10 周 | P2 需求（C3/C6/C8/C9 + Perf-8~9 + UX-5~7 + T-2~3 + F-3~5） | 离线支持、AA 分账、智能记账 |
+| **Phase 5** | 远期 | P3 需求（C10 + Perf-10） | 路由中间件统一、数据可视化增强 |

+
+| 文件 | 行号 | 问题 | 影响 |
+|------|------|------|------|
+| [notifications/index.vue](client/src/pages/notifications/index.vue) | 43 | `<text class="pin-badge">📌</text>` 使用 emoji 作为图钉图标 | 设计规范明确禁止 emoji，必须使用 Icon 组件 |
+
+**修复方向**：将 `📌` 替换为 `<Icon name="pin" ... />`
+
+---
+
+## P2 — 中优先级（4 项）
+
+### 2. stats 趋势条动画缺少 prefers-reduced-motion
+
+| 文件 | 行号 | 问题 | 影响 |
+|------|------|------|------|
+| [stats/index.vue](client/src/pages/stats/index.vue) | 550 | `.trend-bar { transition: width 0.6s ease-out; }` 无 `prefers-reduced-motion` 处理 | 对动画敏感用户不友好 |
+
+**修复方向**：添加 `@media (prefers-reduced-motion: reduce) { .trend-bar { transition: none; } }`
+
+### 3. admin/logs 页面日期选择触发双重请求
+
+| 文件 | 行号 | 问题 | 影响 |
+|------|------|------|------|
+| [admin/logs.vue](client/src/pages/admin/logs.vue) | 181-185, 206-209 | `selectDate()` 直接调用 `loadLogs()`，同时 `watch([filterLevel, selectedDate])` 也触发 `loadLogs()`，导致日期变更时请求发两次 | 浪费带宽，可能导致竞态 |
+
+**修复方向**：`selectDate()` 只设置 `selectedDate.value`，删除手动 `loadLogs()` 调用，由 watcher 统一触发。
+
+### 4. bills 页面列表参数使用 any 类型
+
+| 文件 | 行号 | 问题 | 影响 |
+|------|------|------|------|
+| [bills/index.vue](client/src/pages/bills/index.vue) | 109, 165 | `txList: any[]` 和 `params: any` 丢失类型安全 | 重构时易引入 bug |
+
+**修复方向**：使用 `Transaction[]` 和 `TransactionParams` 类型。
+
+### 5. bills 空状态缺少图标
+
+| 文件 | 行号 | 问题 | 影响 |
+|------|------|------|------|
+| [bills/index.vue](client/src/pages/bills/index.vue) | 82-84 | 空状态只显示文字「暂无账单记录」，无图标 | 与其他页面空状态不一致（其他页面都有 Icon） |
+
+**修复方向**：添加 `<Icon name="edit" :size="48" color="#BFB3B3" />`
+
+---
+
+## P3 — 建议改进（7 项）
+
+### 6. 多处使用 `any` 类型
+
+| 文件 | 行号 | 问题 |
+|------|------|------|
+| [index/index.vue](client/src/pages/index/index.vue) | 168 | `recentTx` 类型 `any[]`，应为 `Transaction[]` |
+| [add/index.vue](client/src/pages/add/index.vue) | 139 | `getCurrentPages()` 结果 cast `as any` |
+| [budget/index.vue](client/src/pages/budget/index.vue) | 93 | `budget` 类型 `any`，应为 `Budget \| null` |
+| [profile/index.vue](client/src/pages/profile/index.vue) | 329 | `allList` 类型 `any[]`，应为 `Transaction[]` |
+| [admin/users.vue](client/src/pages/admin/users.vue) | 99 | `params` 类型 `any`，应为具名类型 |
+| [admin/feedback.vue](client/src/pages/admin/feedback.vue) | 105 | `list` 类型 `any[]`，应使用 Feedback 类型 |
+
+### 7. stats 页面 loadData / loadTabData 代码重复
+
+| 文件 | 行号 | 问题 |
+|------|------|------|
+| [stats/index.vue](client/src/pages/stats/index.vue) | 245-281 | `loadData` 和 `loadTabData` 有大量重复代码（loadSeq、错误处理），可抽取公共函数 |
+
+---
+
+## 总体评价
+
+代码质量整体良好，主要体现在：
+
+- ✅ **认证机制完善**：HMAC-SHA256 token + timingSafeEqual，30天过期
+- ✅ **竞态保护**：bills、stats、notifications 页面均使用 `loadSeq` 防止并发覆盖
+- ✅ **401 队列重试**：`request.ts` 自动重登录 + 队列重试，设计精良
+- ✅ **统一设计系统**：SCSS 变量、mixin 复用度高，Claymorphism 风格统一
+- ✅ **响应格式统一**：后端 API 返回 `{ code, data/message }` 标准格式
+- ✅ **输入校验**：前后端均有校验（金额范围、必填字段、类型白名单）
+- ✅ **参数化查询**：后端 SQL 使用 `?` 占位符，无 SQL 注入风险
+- ✅ **空状态/加载态/错误态**：大部分页面三态齐全
+- ✅ **小程序适配**：胶囊按钮避让 `capsuleRight` 使用正确
+- ✅ **数据加载模式**：`waitForReady()` + `initialLoaded` 守卫模式统一
+- ✅ **动画可访问性**：大部分页面有 `prefers-reduced-motion` 处理
+
+主要改进方向集中在：
+1. 消除 emoji（1 处）
+2. 补全 `prefers-reduced-motion`（1 处）
+3. 修复重复请求（1 处）
+4. 统一空状态样式（1 处）
+5. 减少 `any` 类型使用（6 处）

+# 小菜记账 — 质量迭代设计
+
+日期: 2026-06-08
+
+## 概述
+
+对「小菜记账」进行全面质量迭代，分四个阶段推进：全面扫描 → 缺陷修复 → UI 交互优化 → 系统功能迭代。
+
+## 总体方案：分阶段逐层推进
+
+```
+S1 全面扫描 → S2 缺陷修复 → S3 UI 优化 → S4 功能迭代
+```
+
+每阶段有独立验收标准，后续阶段基于前一阶段的稳定基线。
+
+---
+
+## S1: 全面扫描
+
+### 扫描维度
+
+对每个文件从三个维度同时检查：
+
+#### 🔧 缺陷维度
+- **类型安全**: API 参数类型错误、null/undefined 处理不当、`any` 滥用
+- **边界条件**: 空数据、空字符串、0 值、数组越界
+- **竞态条件**: 快速切换页面时未取消的请求
+- **小程序适配**: 胶囊按钮避让缺失、scroll-view 高度计算错误
+- **内存泄漏**: 未清理的 timer、watcher、事件监听
+- **响应格式**: 后端路由是否统一返回 `{ code, data/message }`
+- **错误码规范**: 是否符合 0=成功, 40001=参数错误, 40300=权限, 40400=不存在, 50000=服务器错误
+
+#### 🎨 UI 维度
+- **加载态**: 是否有 loading/skeleton，避免白屏
+- **空状态**: 是否有友好的空状态提示（图标+文案）
+- **错误态**: 网络错误/超时是否有用户提示
+- **触摸反馈**: 按钮/列表项是否有点击态（`:active` 样式）
+- **动画过渡**: 是否尊重 `prefers-reduced-motion`
+- **设计一致性**: 颜色、圆角、阴影是否使用 SCSS 变量，而非硬编码
+- **触摸目标**: 是否 ≥ 44×44px（小程序最小触摸区域）
+- **emoji 检查**: 是否混用 emoji 代替 Icon 组件（设计规范禁止 emoji）
+
+#### 🚀 功能维度
+- **数据完整性**: 分页是否正确、筛选是否生效
+- **校验完整性**: 前端+后端是否都有输入校验
+- **错误处理**: catch 块是否有用户提示（而非静默失败）
+- **数据流**: API → store → 组件数据流是否清晰，避免 prop drilling
+
+### 扫描分组
+
+| 扫描组 | 覆盖范围 | 文件数（约） |
+|--------|---------|------------|
+| 组 1: 核心页面 | 首页、记账、账单、统计 + 对应 store + API | ~10 |
+| 组 2: 用户 & 设置 | 个人、编辑资料、预算、分类管理、群组、通知、反馈、隐私 | ~12 |
+| 组 3: 管理后台 | 仪表盘、用户管理、公告、反馈、配置、日志、埋点 | ~10 |
+| 组 4: 后端路由 | 15 个路由 + 中间件 + 工具函数 | ~20 |
+| 组 5: 公共组件 & 基础设施 | Icon、Numpad、TransactionItem、Skeleton、request、tracker 等 | ~10 |
+
+### 产出物
+
+每个扫描组输出结构化发现清单，每条发现包含：
+- **优先级**: P0(立即)/P1(高)/P2(中)/P3(低)
+- **文件**: 精确到行号
+- **问题描述**: 清晰说明缺陷/问题
+- **影响**: 用户可见影响
+
+所有发现汇总到统一清单，供审核和排期。
+
+### 优先级定义
+
+| 级别 | 含义 | 示例 |
+|------|------|------|
+| P0 | 数据丢失/安全/崩溃 | 金额计算错误、SQL 注入、白屏 |
+| P1 | 功能不可用/严重体验问题 | 按钮无响应、数据不刷新、接口报错 |
+| P2 | 体验不佳/边界情况 | 空状态缺失、加载闪烁、动画卡顿 |
+| P3 | 建议改进 | 代码整洁、变量命名、注释补充 |
+
+---
+
+## S2: 缺陷修复（扫描后细化）
+
+- 按 P0 → P1 → P2 顺序修复
+- 每个修复前先写测试用例复现
+- 修复后验证已有测试通过
+
+---
+
+## S3: UI 交互优化（扫描后细化）
+
+- 统一加载/空/错误状态组件
+- 统一触摸反馈模式
+- 动画一致性检查
+- 无障碍改进
+
+---
+
+## S4: 系统功能迭代（扫描后细化）
+
+- 基于扫描发现的功能缺口
+- 新功能需写 spec → plan → implement
+
+---
+
+## 不涉及的范围
+
+- 不修改 `dist/` 目录
+- 不修改 lock 文件
+- 不做无关重构
+- 不做数据库结构大改（如需迁移需单独评审）
