+
+# Bug修复技能
+
+## 技能概述
+
+专门用于诊断和修复项目中的bug，强调谨慎的分析流程和充分的交互式确认，确保修复的准确性和完整性，避免引入新的问题或破坏现有功能。
+
+## ⚠️ 强制交互规则（MUST FOLLOW）
+
+**遇到需要用户确认的情况时，必须立即调用 `question` 工具：**
+
+❌ **禁止**："我需要向用户确认..."、"请用户回答..."、"在Plan模式下建议先询问..."  
+✅ **必须**：直接调用工具，不要描述或延迟
+
+**调用格式**：
+```javascript
+question({
+  header: "问题确认",
+  questions: [{
+    question: "具体触发场景是什么？",
+    options: ["新增时", "修改时", "批量导入时", "定时任务时", "其他"]
+  }]
+})
+```
+
+**规则**：
+- 每次最多 **3个问题**
+- 每个问题 **3-6个选项**（穷举常见情况 + "其他"兜底）
+- 用户通过**上下键导航**选择
+- 适用于**所有模式**（Build/Plan）
+
+## 执行原则
+
+### 1. 充分理解问题（必要时交互确认）
+
+**触发条件**：
+- 用户对bug的描述含糊不清
+- 问题复现步骤不完整
+- 预期行为与实际行为表述存在歧义
+- 涉及多个可能的问题根因
+
+**执行策略**：
+- ✅ **立即调用 `question` 工具**（不要描述，直接执行）
+- ✅ **暂停其他操作**，不要基于假设进行修复
+- ✅ 澄清：错误现象、触发条件、预期行为、是否有日志
+
+### 2. 风险评估与影响分析（必要时交互确认）
+
+**触发条件**：
+- 发现潜在的边界情况用户未提及
+- 代码修改可能影响其他功能模块
+- 存在多种修复方案，各有利弊
+- 发现可能的性能、安全或兼容性隐患
+
+**执行策略**：
+- ✅ 代码分析后，**不要直接修改代码**
+- ✅ 报告潜在问题：影响范围、边界情况、测试场景、数据迁移需求
+- ✅ **使用 `question` 工具**让用户选择方案或确认风险
+
+### 3. 关联代码检查（必要时交互确认）
+
+**触发条件**：
+- 发现多个位置存在相似的代码逻辑
+- 修复需要同步更新多个文件
+- 存在可能依赖该bug行为的代码（反模式）
+- 发现测试用例可能基于错误行为编写
+
+**执行策略**：
+- ✅ 使用代码搜索工具查找相似逻辑和调用链
+- ✅ 报告关联代码：是否需要同步修复、依赖关系、测试更新
+- ✅ **使用 `question` 工具**让用户确认修复范围
+
+## 修复流程
+
+### 阶段1: 问题诊断
+1. 阅读用户的bug描述
+2. 定位相关代码文件（使用 semantic_search, grep_search）
+3. 分析代码逻辑和调用链
+4. **触发点1**: 如有不明确之处 → **立即调用 `question` 工具**（不要描述计划）
+
+### 阶段2: 根因分析
+1. 确定bug的根本原因
+2. 识别影响范围和边界情况
+3. **触发点2**: 发现用户未考虑的问题 → **立即调用 `question` 工具**
+
+### 阶段3: 方案设计
+1. 设计修复方案
+2. 评估方案的影响和风险
+3. 查找相似代码和依赖关系
+4. **触发点3**: 可能影响其他逻辑 → **立即调用 `question` 工具**
+
+### 阶段4: 实施修复
+1. 获得用户最终确认后执行代码修改
+2. 使用 `multi_replace_string_in_file` 批量修改
+3. 确保修改的原子性和一致性
+
+### 阶段5: 验证建议
+提示用户执行：单元测试（`dotnet test`）、手动测试场景、回归测试
+
+## 反模式与成功标准
+
+❌ **不要**在未明确理解问题的情况下猜测修复
+❌ **不要**在未评估影响范围的情况下直接修改代码
+❌ **不要**假设用户已考虑所有边界情况
+❌ **不要**在发现关联逻辑时仅修复单个位置
+❌ **不要**跳过风险通知直接实施有争议的修复方案
+❌ **不要**修改代码后不提供验证建议
+❌ **不要**描述"我会询问用户..."而不调用 `question` 工具
+❌ **不要**列出问题清单让用户自行回答
+❌ **不要**在Plan模式下说"如果用户确认..."而不执行工具调用
+
+## 成功标准
+
+✅ 用户明确确认问题理解无误（通过 `question` 工具获取）
+✅ 所有潜在风险和影响已向用户说明（通过 `question` 工具确认）
+✅ 修复方案获得用户明确同意（通过 `question` 工具选择）
+✅ 相似逻辑和关联代码已同步处理（如适用）
+✅ 提供了完整的验证和测试建议
+
+## 示例工作流
+
+```
+用户: "策略计算结果不对，加价逻辑有问题"
+
+Agent:
+[阶段1 - 问题诊断]
+我需要确认几个细节：
+1. 具体是哪种类型的策略计算不对？（机票、动态加价、固定加价？）
+2. 能否提供一个具体的测试用例输入和错误输出？
+3. 预期的正确输出是什么？
+
+用户: "动态加价，百分比计算错误，应该是基准价×10%，但实际是×100%"
+
+Agent:
+[阶段2 - 根因分析]
+已定位到问题：
+- 位置: src/Domain.Service/Services/AgentService.cs:234
+- 原因: 百分比未除以100
+
+[阶段3 - 方案设计]
+⚠️ 发现以下需要确认的点：
+
+1. **关联代码**: 在 PolicyService.cs 中发现相似的百分比计算（3处），
+   是否也存在相同问题？
+   
+2. **单元测试**: UnitTestPolicy.cs:67 的断言值为100%，可能基于错误行为，
+   修复后需要更新测试
+
+3. **前端影响**: 如果历史数据按错误逻辑存储，前端展示需要迁移脚本吗？
+
+请确认是否需要一并处理这些关联问题？
+
+用户: "是的，PolicyService 也需要修复，测试用例也要改，历史数据没有存储"
+
+Agent:
+[阶段4 - 实施修复]
+好的，我将修复以下位置：
+1. AgentService.cs:234
+2. PolicyService.cs:156, 178, 201
+3. UnitTestPolicy.cs:67
+
+[执行代码修改...]
+
+[阶段5 - 验证建议]
+修复完成！建议验证：
+1. 运行单元测试: dotnet test
+2. 手动测试场景:
+   - 输入基准价1000，加价10%，期望结果1100
+   - 验证策略列表API返回正确百分比
+3. 回归测试: 检查其他类型策略未受影响
+```
+
+## 适用场景
+
+- ✅ 逻辑错误修复
+- ✅ 空指针异常修复
+- ✅ 数据计算错误
+- ✅ API行为异常
+- ✅ 性能问题修复
+- ✅ 边界条件处理
+
+## 相关技能
+
+- `refactor`: 重构优化（非bug修复）
+- `feature`: 新功能开发
+- `test`: 测试用例编写
+
+## 核心约束（必须遵守）
+1. **禁止开放式提问** - 所有需要用户输入的场景，必须提供选项列表
+2. 每次交互最多提出5个问题，避免信息过载
+3. 选项设计要穷举常见情况，并保留"其他"兜底选项

+
+> 专业的设计技能，用于使用 pancli (pencil tools) 创建现代化、一致的移动端 UI 设计。
+
+## 何时使用此技能
+
+**总是使用此技能当:**
+- 使用 pancli 创建新的 UI 界面或组件
+- 修改现有的 .pen 设计文件
+- 处理亮色/暗色主题设计
+- 为 EmailBill 项目设计移动端优先的界面
+
+**触发条件:**
+- 用户提到 "画设计图"、"设计"、"UI"、"界面"、"pancli"、".pen"
+- 任务涉及 `pencil_*` 工具
+- 创建视觉原型或模型
+
+## 核心设计原则
+
+### 1. 现代移动端优先设计
+
+**布局标准:**

+
+### 5. 布局模式
+
+**页面结构 (Flex 容器):**
+```
+.page-container-flex:
+  - display: flex
+  - flex-direction: column
+  - height: 100%
+  - overflow: hidden
+  
+  结构:
+    1. van-nav-bar (固定高度)
+    2. van-tabs 或 sticky-header
+    3. scroll-content (flex: 1, overflow-y: auto)
+    4. bottom-button 或 van-tabbar (固定)
+```
+
+**导航栏背景透明化 (一致性模式):**
+```css
+/* 设置页面容器背景色 */
+:deep(.van-nav-bar) {
+  background: transparent !important;
+}
+```
+**重要:** 项目中所有视图都采用此模式，使导航栏背景透明，与页面背景融合。实现此效果时，请确保：
+- 页面容器有明确的背景色 (亮色: #FFFFFF, 暗色: #09090B)
+- 导航栏始终使用 `:deep(.van-nav-bar)` 选择器
+- 必须添加 `!important` 覆盖 Vant 默认样式
+- 在 `<style scoped>` 块中添加此规则
+
+**安全区域处理:**
+```css
+/* iPhone 刘海底部内边距 */
+padding-bottom: env(safe-area-inset-bottom, 0px);
+
+/* 状态栏顶部内边距 */
+padding-top: max(0px, calc(env(safe-area-inset-top, 0px) * 0.75));
+```
+
+**固定元素:**
+```css
+.sticky-header {
+  position: sticky;
+  top: 0;
+  z-index: 10;
+  background: var(--van-background-2);
+  border-radius: 12px;
+  box-shadow: 0 2px 8px rgba(0,0,0,0.04);
+  margin: 12px;
+  padding: 12px 16px;
+}
+```
+
+### 6. 交互模式
+
+**触摸反馈:**
+- 激活状态: 点击时 scale(0.95)
+- 涟漪效果: 使用 Vant 内置触摸反馈
+- 悬停状态: 12% 透明度叠加 (网页端)
+
+**加载状态:**
+```
+van-pull-refresh:
+  - 用于顶层可滚动内容
+  - 最小高度: calc(100vh - nav - tabbar)
+  
+van-loading:
+  - 容器内居中
+  - 尺寸: 内联 24px, 页面 32px
+```
+
+**空状态:**
+```
+van-empty:
+  - 图标: 60px 大小
+  - 描述: 14px, var(--van-text-color-2)
+  - 内边距: 垂直 48px
+```
+
+**悬浮操作:**
+```
+van-floating-bubble:
+  - 图标大小: 24px
+  - 位置: 右下角, 距底部 100px (避开 tabbar)
+  - 磁吸: 贴靠 x 轴边缘
+```
+
+### 7. 数据可视化
+
+**预算进度条:**
+```
+渐变逻辑:
+  支出 (0% → 100%):
+    - 0%:  #40a9ff (安全蓝)
+    - 40%: #36cfc9 (青色过渡)
+    - 70%: #faad14 (警告黄)
+    - 100%: #ff4d4f (危险红)
+  
+  收入 (0% → 100%):
+    - 0%:  #f5222d (深红 - 未开始)
+    - 45%: #ffcccc (浅红)
+    - 50%: #f0f2f5 (中性灰)
+    - 55%: #bae7ff (浅蓝)
+    - 100%: #1890ff (深蓝 - 达成)
+```
+
+**金额显示:**
+```css
+.amount {
+  font-family: 'DIN Alternate', system-ui;
+  font-weight: 600;
+  font-variant-numeric: tabular-nums;
+}
+
+.expense { color: var(--van-danger-color); }
+.income { color: var(--van-success-color); }
+```
+
+**图表 (如果使用):**
+- 折线图: 2px 笔画, 圆角连接
+- 柱状图: 8px 圆角, 4px 间距
+- 颜色: 使用语义色阶
+- 网格线: 1px, 8% 透明度
+
+### 8. 主题切换 (亮色/暗色)
+
+**实现策略:**
+```javascript
+// 自动检测系统偏好
+const isDark = window.matchMedia('(prefers-color-scheme: dark)').matches
+theme.value = isDark ? 'dark' : 'light'
+document.documentElement.setAttribute('data-theme', theme.value)
+```
+
+**设计文件要求:**
+- **必须同时创建亮色和暗色变体**
+- 使用 Vant 的主题变量 (自动切换)
+- 测试对比度: WCAG AA 最低标准 (文本 4.5:1)
+- 暗色模式适配:
+  - 减少卡片阴影至 0 2px 8px rgba(0,0,0,0.24)
+  - 增加边框对比度
+  - 白色文本柔化至 #e5e5e5
+
+**pancli 工作流:**
+```
+1. 先创建亮色主题设计
+2. 复制帧用于暗色模式
+3. 使用 replace_all_matching_properties 批量更新:
+   - 背景颜色
+   - 文本颜色
+   - 边框颜色
+4. 手动调整阴影和叠加
+5. 命名帧: "[屏幕名称] - Light" / "[屏幕名称] - Dark"
+```
+
+### 9. 命名约定
+
+**帧名称:**
+```
+格式: [模块] - [屏幕] - [变体]
+
+示例:
+  ✅ Budget - List View - Light
+  ✅ Budget - Edit Dialog - Dark
+  ✅ Transaction - Card Component
+  ✅ Statistics - Chart Section
+  
+  ❌ Screen1
+  ❌ Frame_Copy_2
+  ❌ New Design
+```
+
+**组件层级:**
+```
+可复用组件:
+  - 前缀 "Component/"
+  - 示例: "Component/BudgetCard"
+  
+屏幕:
+  - 按模块分组
+  - 示例: "Budget/ListView", "Budget/EditForm"
+```
+
+**图层命名:**
+```
+内部元素可用中文:
+  ✅ 预算卡片背景
+  ✅ 金额文本
+  ✅ 操作按钮组
+  
+组件用英文:
+  ✅ CardBackground
+  ✅ AmountLabel
+  ✅ ActionButtons
+```
+
+### 10. 质量检查清单
+
+**完成设计前:**
+- [ ] 同时创建了亮色和暗色主题
+- [ ] 所有文本使用真实中文业务术语 (无 Lorem Ipsum)
+- [ ] 交互元素 ≥ 44x44px
+- [ ] 间距遵循 8px 网格
+- [ ] 颜色使用语义变量 (非硬编码十六进制)
+- [ ] 圆角: 12px/16px/24px 保持一致
+- [ ] 尊重安全区域边距 (底部: 50px + 安全区域)
+- [ ] 帧正确命名 模块/屏幕/变体
+- [ ] 可复用组件标记为 `reusable: true`
+- [ ] 字号匹配字号比例 (12/14/16/18/24)
+- [ ] 数字数据使用 DIN Alternate
+- [ ] 无 AI 生成的占位内容
+- [ ] 已截图并视觉验证
+- [ ] 导航栏背景设置为透明 (`:deep(.van-nav-bar) { background: transparent !important; }`)
+
+**无障碍:**
+- [ ] 正文对比度 ≥ 4.5:1
+- [ ] 大文本对比度 ≥ 3:1 (18px+)
+- [ ] 触摸目标清晰分离 (最小 8px 间距)
+- [ ] 颜色不是信息的唯一指示器
+
+## PANCLI 工作流程
+
+### 阶段 1: 设置与风格选择
+
+```typescript
+// 1. 获取编辑器状态
+pencil_get_editor_state(include_schema: true)
+
+// 2. 获取设计指南
+pencil_get_guidelines(topic: "landing-page") // 或 "design-system"
+
+// 3. 选择合适的风格指南
+pencil_get_style_guide_tags() // 获取可用标签
+
+// 4. 使用标签获取风格指南
+pencil_get_style_guide(tags: [
+  "mobile",        // 必需
+  "webapp",        // 类应用界面
+  "modern",        // 简洁, 现代
+  "minimal",       // 避免杂乱
+  "professional",  // 商业环境
+  "blue",          // 主色提示
+  "fintech"        // 如果可用
+])
+```
+
+### 阶段 2: 创建亮色主题设计
+
+```typescript
+// 5. 读取现有组件 (如果有)
+pencil_batch_get(
+  filePath: "designs/emailbill.pen",
+  patterns: [{ reusable: true }],
+  readDepth: 2
+)
+
+// 6. 创建亮色主题屏幕
+pencil_batch_design(
+  filePath: "designs/emailbill.pen",
+  operations: `
+    screen=I(document, {
+      type: "frame",
+      name: "Budget - List View - Light",
+      width: 375,
+      height: 812,
+      fill: "#FFFFFF",
+      layout: "vertical",
+      placeholder: true
+    })
+    
+    navbar=I(screen, {
+      type: "frame",
+      name: "Navbar",
+      width: "fill_container",
+      height: 44,
+      fill: "transparent",
+      layout: "horizontal",
+      padding: [12, 16, 12, 16]
+    })
+    
+    title=I(navbar, {

+      textColor: "#1A1A1A"
+    })
+    
+    // ... 更多操作
+  `
+)
+```
+
+### 阶段 3: 创建暗色主题变体
+
+```typescript
+// 7. 复制亮色主题帧
+pencil_batch_design(
+  operations: `
+    darkScreen=C("light-screen-id", document, {
+      name: "Budget - List View - Dark",
+      positionDirection: "right",
+      positionPadding: 48
+    })
+  `
+)
+
+// 8. 批量替换暗色主题颜色
+pencil_replace_all_matching_properties(
+  parents: ["dark-screen-id"],
+  properties: {
+    fillColor: [
+      { from: "#FFFFFF", to: "#09090B" },   // 页面背景
+      { from: "#F6F7F8", to: "#18181B" },   // 卡片背景
+      { from: "#F5F5F5", to: "#27272A" }    // 边框
+    ],
+    textColor: [
+      { from: "#1A1A1A", to: "#F4F4F5" },   // 主文本
+      { from: "#6B7280", to: "#A1A1AA" },   // 次要
+      { from: "#9CA3AF", to: "#71717A" }    // 三级
+    ]
+  }
+)
+
+// 9. 手动调整暗色模式阴影 (如需要)
+pencil_batch_design(
+  operations: `
+    U("dark-card-id", {
+      shadow: {
+        x: 0,
+        y: 2,
+        blur: 8,
+        color: "rgba(0,0,0,0.24)"
+      }
+    })
+  `
+)
+```
+
+### 阶段 4: 验证
+
+```typescript
+// 10. 对两种主题截图
+pencil_get_screenshot(nodeId: "light-screen-id")
+pencil_get_screenshot(nodeId: "dark-screen-id")
+
+// 11. 检查布局问题
+pencil_snapshot_layout(
+  parentId: "light-screen-id",
+  problemsOnly: true
+)
+
+// 12. 验证所有唯一属性
+pencil_search_all_unique_properties(
+  parents: ["light-screen-id"],
+  properties: ["fillColor", "textColor", "fontSize"]
+)
+```
+
+## 代码库实际示例
+
+### 示例 1: 预算卡片组件
+
+```
+组件结构:
+  BudgetCard (375x120px)
+    ├─ CardBackground (#ffffff, 16px 圆角, 阴影)
+    ├─ HeaderRow (水平布局)
+    │   ├─ CategoryName (16px, 600 粗细)
+    │   └─ PeriodLabel (12px, 次要颜色)
+    ├─ ProgressBar (基于比例渐变)
+    │   └─ ProgressFill (高度: 8px, 圆角: 4px)
+    ├─ AmountRow (水平布局, 两端对齐)
+    │   ├─ CurrentAmount (DIN, 18px, 危险色)
+    │   ├─ LimitAmount (DIN, 14px, 次要)
+    │   └─ RemainingAmount (DIN, 14px, 成功色)
+    └─ FooterActions (可选, 储蓄按钮)
+```
+
+**pancli 实现:**
+```typescript
+card=I(parent, {
+  type: "frame",
+  name: "BudgetCard",
+  width: "fill_container",
+  height: 120,
+  fill: "#ffffff",
+  cornerRadius: [16, 16, 16, 16],
+  shadow: { x: 0, y: 2, blur: 12, color: "rgba(0,0,0,0.08)" },
+  stroke: { color: "#ebedf0", thickness: 1 },
+  padding: [16, 16, 16, 16],
+  layout: "vertical",
+  gap: 12,
+  placeholder: true
+})
+
+header=I(card, {
+  type: "frame",
+  layout: "horizontal",
+  width: "fill_container",
+  height: "hug_contents"
+})
+
+categoryName=I(header, {
+  type: "text",

+
+// 带渐变的进度条
+progressBar=I(card, {
+  type: "frame",
+  width: "fill_container",
+  height: 8,
+  fill: "#f0f0f0",
+  cornerRadius: [4, 4, 4, 4]
+})
+
+progressFill=I(progressBar, {

+  fill: "linear-gradient(90deg, #40a9ff 0%, #faad14 100%)",
+  cornerRadius: [4, 4, 4, 4]
+})
+```
+
+### 示例 2: 带日期选择器的固定头部
+
+```
+固定头部模式 (来自 BudgetView):
+  ├─ 位置: sticky, top: 0
+  ├─ 背景: var(--van-background-2)
+  ├─ 圆角: 12px
+  ├─ 阴影: 0 2px 8px rgba(0,0,0,0.04)
+  ├─ 内边距: 12px 16px
+  ├─ 内容: "2024年1月" + 下拉箭头图标
+```
+
+### 示例 3: 滑动删除列表项
+
+```
+van-swipe-cell 模式:
+  ├─ 内容: BudgetCard 组件
+  ├─ 右侧操作: 删除按钮
+  │   ├─ 宽度: 60px
+  │   ├─ 背景: var(--van-danger-color)
+  │   ├─ 文本: "删除"
+  │   └─ 全高 (100%)
+```
+
+## 避免的反模式
+
+**❌ 不要这样做:**
+```
+// 通用 AI 生成内容
+title=I(navbar, {
+  type: "text",
+  content: "Dashboard", // ❌ 使用 "预算管理" 代替
+  fontSize: 20,         // ❌ 按字号比例使用 16px
+  fontWeight: "bold"    // ❌ 使用数字值 600
+})
+
+// 不一致的间距
+card=I(parent, {
+  padding: [15, 13, 17, 14] // ❌ 使用 8px 网格: [16, 16, 16, 16]
+})
+
+// 硬编码颜色而非语义
+amount=I(card, {
+  textColor: "#ff0000" // ❌ 使用 var(--van-danger-color) 或 "#ee0a24"
+})
+
+// 缺少暗色模式
+// ❌ 只创建亮色主题没有暗色变体
+
+// 糟糕的命名
+frame=I(document, {
+  name: "Frame_123" // ❌ 使用 "Budget - List View - Light"
+})
+```
+
+**✅ 应该这样做:**
+```typescript
+// 真实业务术语
+title=I(navbar, {
+  type: "text",
+  content: "预算管理",
+  fontSize: 16,
+  fontWeight: "600",
+  textColor: "#323233"
+})
+
+// 一致的 8px 网格间距
+card=I(parent, {
+  padding: [16, 16, 16, 16],
+  gap: 12
+})
+
+// 语义颜色变量
+amount=I(card, {
+  textColor: "#ee0a24", // 一致的危险色
+  fontFamily: "DIN Alternate"
+})
+
+// 总是创建两种主题
+lightScreen=I(document, { name: "Budget - List - Light" })
+darkScreen=C(lightScreen, document, { 
+  name: "Budget - List - Dark",
+  positionDirection: "right"
+})
+
+// 清晰的描述性名称
+card=I(parent, {
+  name: "BudgetCard",
+  reusable: true
+})
+```

+## Vue 3 Composition API Research - Modular Architecture Best Practices
+
+### 研究日期: 2026-02-03
+
+---
+
+## 1. 官方 Vue 3 组件组织原则
+
+### 1.1 Composables 用于代码组织
+来源: Vue 官方文档 - https://vuejs.org/guide/reusability/composables
+
+**核心原则:**
+- Composables 不仅用于复用,也用于**代码组织**
+- 当组件变得过于复杂时,应该将逻辑按**关注点分离**提取到更小的函数中
+- 可以将提取的 composables 视为**组件级别的服务**,它们可以相互通信
+
+**官方示例模式:**
+```vue
+<script setup>
+import { useFeatureA } from './featureA.js'
+import { useFeatureB } from './featureB.js'
+import { useFeatureC } from './featureC.js'
+
+const { foo, bar } = useFeatureA()
+const { baz } = useFeatureB(foo)
+const { qux } = useFeatureC(baz)
+</script>
+```
+
+**关键洞察:**
+- Composables 应返回**普通对象**包含多个 refs,保持响应式
+- 避免返回 reactive 对象,因为解构会失去响应性
+- Composables 可以接收其他 composables 的返回值作为参数
+
+---
+
+## 2. 代码分割与懒加载
+
+### 2.1 defineAsyncComponent 用于模块懒加载
+来源: Vue 官方文档 - https://github.com/vuejs/docs/blob/main/src/guide/best-practices/performance.md
+
+**适用场景:**
+- 将大型组件树分割成独立的 chunks
+- 仅在组件渲染时才加载,改善初始加载时间
+
+```js
+import { defineAsyncComponent } from 'vue'
+
+// Foo.vue 及其依赖被单独打包成一个 chunk
+// 只有在组件被渲染时才会按需获取
+const Foo = defineAsyncComponent(() => import('./Foo.vue'))
+```
+
+### 2.2 动态导入用于 JS 代码分割
+```js
+// lazy.js 及其依赖会被分割成单独的 chunk
+// 只在 loadLazy() 被调用时才加载
+function loadLazy() {
+  return import('./lazy.js')
+}
+```
+
+---
+
+## 3. 真实世界的模块化架构模式
+
+### 3.1 Dashboard 模块化架构 - 成功案例
+
+**案例 1: Soybean Admin (MIT License)**
+来源: https://github.com/soybeanjs/soybean-admin/blob/main/src/views/home/index.vue
+
+```vue
+<script setup lang="ts">
+import { computed } from 'vue';
+import { useAppStore } from '@/store/modules/app';
+import HeaderBanner from './modules/header-banner.vue';
+import CardData from './modules/card-data.vue';
+import LineChart from './modules/line-chart.vue';
+import PieChart from './modules/pie-chart.vue';
+import ProjectNews from './modules/project-news.vue';
+import CreativityBanner from './modules/creativity-banner.vue';
+
+const appStore = useAppStore();
+const gap = computed(() => (appStore.isMobile ? 0 : 16));
+</script>
+```
+
+**架构特点:**
+- Index.vue 作为**容器组件**,只负责布局和响应式计算
+- 每个 modules/*.vue 是**独立的功能模块**
+- 模块命名清晰: header-banner, card-data, line-chart 等
+- 使用 Pinia store 进行状态共享
+
+**案例 2: Art Design Pro (MIT License)**
+来源: https://github.com/Daymychen/art-design-pro/blob/main/src/views/dashboard/ecommerce/index.vue
+
+```vue
+<script setup lang="ts">
+  import Banner from './modules/banner.vue'
+  import TotalOrderVolume from './modules/total-order-volume.vue'
+  import TotalProducts from './modules/total-products.vue'
+  import SalesTrend from './modules/sales-trend.vue'
+  import SalesClassification from './modules/sales-classification.vue'
+  import TransactionList from './modules/transaction-list.vue'
+  import HotCommodity from './modules/hot-commodity.vue'
+  import RecentTransaction from './modules/recent-transaction.vue'
+  import AnnualSales from './modules/annual-sales.vue'
+  import ProductSales from './modules/product-sales.vue'
+  import SalesGrowth from './modules/sales-growth.vue'
+  import CartConversionRate from './modules/cart-conversion-rate.vue'
+  import HotProductsList from './modules/hot-products-list.vue'
+
+  defineOptions({ name: 'Ecommerce' })
+</script>
+```
+
+**架构特点:**
+- 电商 dashboard 包含 13 个独立模块
+- 每个模块代表一个业务功能卡片
+- Index.vue **不传递数据**,模块自治
+
+---
+
+## 4. 模块间通信模式
+
+### 4.1 defineEmits 用于子到父通信
+来源: Vue 核心仓库 - https://github.com/vuejs/core/blob/main/packages/runtime-core/src/apiSetupHelpers.ts
+
+**TypeScript 类型声明模式:**
+```ts
+const emit = defineEmits<{
+  'update:modelValue': [value: string];
+  'change': [event: Event];
+  'custom-event': [payload: CustomPayload];
+}>();
+```
+
+**Runtime 声明模式:**
+```js
+const emit = defineEmits(['change', 'update'])
+```
+
+### 4.2 Props 模式 - 数据传递 vs 自取数据
+
+**案例研究: Halo CMS (GPL-3.0)**
+来源: https://github.com/halo-dev/halo/blob/main/ui/console-src/modules/system/users/components/GrantPermissionModal.vue
+
+```vue
+<script setup lang="ts">
+import { computed, onMounted, ref } from "vue";
+import { useI18n } from "vue-i18n";
+import { useFetchRoles, useFetchRoleTemplates } from "../composables/use-role";
+
+const props = withDefaults(
+  defineProps<{
+    user?: User;
+  }>(),
+  {
+    user: undefined,
+  }
+);
+
+const emit = defineEmits<{
+  (event: "close"): void;
+}>();
+
+// 模块自己获取数据
+onMounted(async () => {
+  await fetchRoles();
+});
+</script>
+```
+
+**模式总结:**
+- **Props 传递身份标识** (如 user ID),而非完整数据
+- **模块自己获取详细数据** (通过 composables)
+- 这样保持模块的**高内聚低耦合**
+
+---
+
+## 5. 何时模块应该自取数据 vs 接收 Props
+
+### 5.1 自取数据的场景
+- 模块是**独立的业务单元**(如日历、统计卡片)
+- 数据获取逻辑属于模块内部关注点
+- 模块需要**定期刷新**或**重新加载**数据
+- 多个平行模块各自管理自己的状态
+
+**示例:**
+```vue
+<!-- 统计卡片模块 - 自己获取数据 -->
+<script setup lang="ts">
+const { data, loading } = useBudgetStats()
+
+onMounted(() => {
+  loadStats()
+})
+</script>
+```
+
+### 5.2 接收 Props 的场景
+- 模块是**展示组件**(Presentational Component)
+- 父组件需要**协调多个子组件**的数据
+- 数据来源于**全局状态管理**(如 Pinia store)
+- 需要在父组件层面做**数据聚合或转换**
+
+**示例:**
+```vue
+<!-- 数据展示组件 - 接收 props -->
+<script setup lang="ts">
+const props = defineProps<{
+  stats: BudgetStats
+  loading: boolean
+}>()
+</script>
+```
+
+---
+
+## 6. TypeScript vs JavaScript 在 Vue 3 项目中
+
+### 6.1 EmailBill 项目的选择
+**当前状况:**
+- ESLint 配置中禁用了 TypeScript 规则
+- 使用 `<script setup lang="ts">` 但不强制类型检查
+- 轻量级类型提示,不追求严格类型安全
+
+**何时避免 TypeScript:**
+- 小型项目,团队更熟悉 JavaScript
+- 快速原型开发
+- 避免 TypeScript 配置和类型定义的复杂度
+- 保持构建速度和开发体验的流畅
+
+**何时使用 TypeScript:**
+- 大型团队协作
+- 复杂的状态管理和数据流
+- 需要严格的 API 契约
+- 长期维护的企业级应用
+
+---
+
+## 7. 模块化架构的最佳实践总结
+
+### 7.1 目录结构推荐
+```
+views/
+  calendar/
+    Index.vue              # 容器组件,布局和协调
+    modules/
+      CalendarView.vue     # 日历展示模块(自取数据)
+      MonthlyStats.vue     # 月度统计模块(自取数据)
+      QuickActions.vue     # 快捷操作模块(事件驱动)
+    composables/
+      useCalendarData.ts   # 日历数据获取逻辑
+      useMonthlyStats.ts   # 统计数据获取逻辑
+```
+
+### 7.2 组件职责划分
+
+**Index.vue (容器组件):**
+- 布局管理和响应式设计
+- 协调模块间的通信(如果需要)
+- 全局状态初始化
+- **不应包含业务逻辑**
+
+**modules/*.vue (功能模块):**
+- 独立的业务功能单元
+- 自己管理数据获取和状态
+- 通过 emits 向父组件通信
+- 高内聚,低耦合
+
+**composables/*.ts (可复用逻辑):**
+- 数据获取逻辑
+- 业务规则计算
+- 状态管理辅助
+- 可在多个组件间共享
+
+### 7.3 通信模式推荐
+
+**模块向上通信 (Child → Parent):**
+```ts
+const emit = defineEmits<{
+  'date-changed': [date: Date]
+  'item-clicked': [item: CalendarItem]
+}>()
+```
+
+**模块间通信 (Sibling ↔ Sibling):**
+- 通过**父组件中转**事件
+- 或使用**全局事件总线**(如 mitt)
+- 或使用**Pinia store** 共享状态
+
+---
+
+## 8. 关键洞察和建议
+
+### 8.1 高内聚模块设计
+- 每个模块应该是**自治的**,包含自己的数据获取、状态管理和事件处理
+- Index.vue 应该是**轻量级的协调者**,而非数据的中央枢纽
+
+### 8.2 Props vs 自取数据的平衡
+- **身份标识和配置通过 props** (如 userId, date, theme)
+- **业务数据通过模块自取** (如 stats, calendar items)
+
+### 8.3 避免过度抽象
+- 不要为了复用而复用
+- 优先考虑**代码的清晰度**而非极致的 DRY
+- Composables 应该解决**真实的重复问题**,而非预测性的抽象
+
+---

+# Date Navigation Implementation Learnings
+
+## Implementation Details
+- Added left/right arrow navigation to both `StatisticsView.vue` and `BudgetView.vue`
+- Used `<van-icon name="arrow-left" />` and `<van-icon name="arrow" />` for directional arrows
+- Text center remains clickable for date picker popup
+- Arrows use `@click.stop` to prevent event propagation
+
+## StatisticsView.vue
+- `navigateDate(direction)` method handles both month and year modes
+- Month mode: handles year boundaries (Jan -> Dec of previous year, Dec -> Jan of next year)
+- Year mode: increments/decrements year directly
+- Resets `showAllExpense` state on navigation
+
+## BudgetView.vue
+- `navigateDate(direction)` uses native Date object manipulation
+- `setMonth()` automatically handles month/year boundaries
+- Updates `selectedDate` ref which triggers data fetching via watcher
+
+## Styling
+- Added `.nav-date-picker` with flex layout and 12px gap
+- `.nav-date-text` for clickable center text
+- `.nav-arrow` with 8px horizontal padding for touch-friendly targets
+- Active state opacity transition for visual feedback
+- Arrow font size: 18px for clear visibility
+
+## Key Decisions
+- Used `@click.stop` on arrows to prevent opening date picker
+- Centered layout preserved (van-nav-bar default behavior)
+- Consistent styling across both views
+- Touch-friendly padding for mobile UX
+
+## Verification
+- ESLint: No new errors introduced
+- Build: Successful compilation
+- Date math: Correctly handles month/year boundaries

+# Decisions - Statistics Year Selection Enhancement
+
+## [2026-01-28] Architecture Decisions
+
+### Frontend Implementation Strategy
+
+#### 1. Date Picker Mode Toggle
+- Add a toggle switch in the date picker popup to switch between "按月" (month) and "按年" (year) modes
+- When "按年" selected: use `columns-type="['year']"`
+- When "按月" selected: use `columns-type="['year', 'month']` (current behavior)
+
+#### 2. State Management
+- Add `dateSelectionMode` ref: `'month'` | `'year'`
+- When year-only mode: set `currentMonth = 0` to indicate full year
+- Keep `currentYear` as integer (unchanged)
+- Update `selectedDate` array dynamically based on mode:
+  - Year mode: `['YYYY']`
+  - Month mode: `['YYYY', 'MM']`
+
+#### 3. Display Logic
+- Nav bar title: `currentYear年` when `currentMonth === 0`, else `currentYear年currentMonth月`
+- Chart titles: Update to reflect year or year-month scope
+
+#### 4. API Calls
+- Pass `month: currentMonth.value || 0` to all API calls
+- Backend will handle month=0 as year-only query
+
+### Backend Implementation Strategy
+
+#### 1. Repository Layer Change
+**File**: `Repository/TransactionRecordRepository.cs`
+**Method**: `BuildQuery()` lines 81-86
+
+```csharp
+if (year.HasValue)
+{
+    if (month.HasValue && month.Value > 0)
+    {
+        // Specific month
+        var dateStart = new DateTime(year.Value, month.Value, 1);
+        var dateEnd = dateStart.AddMonths(1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+    else
+    {
+        // Entire year
+        var dateStart = new DateTime(year.Value, 1, 1);
+        var dateEnd = new DateTime(year.Value + 1, 1, 1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+}
+```
+
+#### 2. Service Layer
+- No changes needed - services already pass month parameter to repository
+- Services will receive month=0 for year-only queries
+
+#### 3. API Controller
+- No changes needed - already accepts year/month parameters
+
+### Testing Strategy
+
+#### Backend Tests
+- Test year-only query returns all transactions for that year
+- Test month-specific query still works
+- Test edge cases: year boundaries, leap years
+
+#### Frontend Tests
+- Test toggle switches picker mode correctly
+- Test year selection updates state and fetches data
+- Test display updates correctly for year vs year-month
+
+### User Experience Flow
+
+1. User clicks date picker in nav bar
+2. Popup opens with toggle: "按月 | 按年"
+3. User selects mode (default: 按月 for backward compatibility)
+4. User selects date(s) and confirms
+5. Statistics refresh with new scope
+6. Display updates to show scope (year or year-month)

+# Issues - Statistics Year Selection Enhancement
+
+## [2026-01-28] Backend Repository Limitation
+
+### Issue
+`TransactionRecordRepository.BuildQuery()` requires both year AND month parameters to be present. Year-only queries (month=null or month=0) are not supported.
+
+### Impact
+- Cannot query full-year statistics from the frontend
+- Current implementation only supports month-level granularity
+- All statistics endpoints rely on `QueryAsync(year, month, ...)`
+
+### Solution
+Modify `BuildQuery()` method in `Repository/TransactionRecordRepository.cs` to support:
+1. Year-only queries (when year provided, month is null or 0)
+2. Month-specific queries (when both year and month provided - current behavior)
+
+### Implementation Location
+- File: `Repository/TransactionRecordRepository.cs`
+- Method: `BuildQuery()` lines 81-86
+- Also need to update service layer to handle month=0 or null
+
+### Testing Requirements
+- Test year-only query returns all transactions for that year
+- Test month-specific query still works as before
+- Test edge cases: leap years, year boundaries
+- Verify all statistics endpoints work with year-only mode

+# Learnings - Statistics Year Selection Enhancement
+
+## [2026-01-28] Initial Analysis
+
+### Current Implementation
+- **File**: `Web/src/views/StatisticsView.vue`
+- **Current picker**: `columns-type="['year', 'month']` (year-month only)
+- **State variables**:
+  - `currentYear` - integer year
+  - `currentMonth` - integer month (1-12)
+  - `selectedDate` - array `['YYYY', 'MM']` for picker
+- **API calls**: All endpoints use `{ year, month }` parameters
+
+### Vant UI Year-Only Pattern
+- **Key prop**: `columns-type="['year']"`
+- **Picker value**: Single-element array `['YYYY']`
+- **Confirmation**: `selectedValues[0]` contains year string
+
+### Implementation Strategy
+1. Add UI toggle to switch between year-month and year-only modes
+2. When year-only selected, set `currentMonth = 0` or null to indicate full year
+3. Backend API already supports year-only queries (when month=0 or null)
+4. Update display logic to show "YYYY年" vs "YYYY年MM月"
+
+### API Compatibility - CRITICAL FINDING
+- **Backend limitation**: `TransactionRecordRepository.BuildQuery()` (lines 81-86) requires BOTH year AND month
+- Current logic: `if (year.HasValue && month.HasValue)` - year-only queries are NOT supported
+- **Must modify repository** to support year-only queries:
+  - When year provided but month is null/0: query entire year (Jan 1 to Dec 31)
+  - When both year and month provided: query specific month (current behavior)
+- All statistics endpoints use `QueryAsync(year, month, ...)` pattern
+
+### Required Backend Changes
+**File**: `Repository/TransactionRecordRepository.cs`
+**Method**: `BuildQuery()` lines 81-86
+**Change**: Modify year/month filtering logic to support year-only queries
+
+```csharp
+// Current (line 81-86):
+if (year.HasValue && month.HasValue)
+{
+    var dateStart = new DateTime(year.Value, month.Value, 1);
+    var dateEnd = dateStart.AddMonths(1);
+    query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+}
+
+// Needed:
+if (year.HasValue)
+{
+    if (month.HasValue && month.Value > 0)
+    {
+        // Specific month
+        var dateStart = new DateTime(year.Value, month.Value, 1);
+        var dateEnd = dateStart.AddMonths(1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+    else
+    {
+        // Entire year
+        var dateStart = new DateTime(year.Value, 1, 1);
+        var dateEnd = new DateTime(year.Value + 1, 1, 1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+}
+```
+
+### Existing Patterns
+- BudgetView.vue uses same year-month picker pattern
+- Dayjs used for all date formatting: `dayjs().format('YYYY-MM-DD')`
+- Date picker values always arrays for Vant UI
+## [2026-01-28] Repository BuildQuery() Enhancement
+
+### Implementation Completed
+- **File Modified**: `Repository/TransactionRecordRepository.cs` lines 81-94
+- **Change**: Updated year/month filtering logic to support year-only queries
+
+### Logic Changes
+```csharp
+// Old: Required both year AND month
+if (year.HasValue && month.HasValue) { ... }
+
+// New: Support year-only queries
+if (year.HasValue)
+{
+    if (month.HasValue && month.Value > 0)
+    {
+        // 查询指定年月
+        var dateStart = new DateTime(year.Value, month.Value, 1);
+        var dateEnd = dateStart.AddMonths(1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+    else
+    {
+        // 查询整年数据（1月1日到下年1月1日）
+        var dateStart = new DateTime(year.Value, 1, 1);
+        var dateEnd = new DateTime(year.Value + 1, 1, 1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+}
+```
+
+### Behavior
+- **Month-specific** (month.HasValue && month.Value > 0): Query from 1st of month to 1st of next month
+- **Year-only** (month is null or 0): Query from Jan 1 to Jan 1 of next year
+- **No year provided**: No date filtering applied
+
+### Verification
+- All 14 tests pass: `dotnet test WebApi.Test/WebApi.Test.csproj`
+- No breaking changes to existing functionality
+- Chinese comments added for business logic clarity
+
+### Key Pattern
+- Use `month.Value > 0` check to distinguish year-only (0/null) from month-specific (1-12)
+- Date range is exclusive on upper bound (`< dateEnd`) to avoid including boundary dates
+
+## [2026-01-28] Frontend Year-Only Selection Implementation
+
+### Changes Made
+**File**: `Web/src/views/StatisticsView.vue`
+
+#### 1. Nav Bar Title Display (Line 12)
+- Updated to show "YYYY年" when `currentMonth === 0`
+- Shows "YYYY年MM月" when month is selected
+- Template: `{{ currentMonth === 0 ? \`${currentYear}年\` : \`${currentYear}年${currentMonth}月\` }}`
+
+#### 2. Date Picker Popup (Lines 268-289)
+- Added toggle switch using `van-tabs` component
+- Two modes: "按月" (month) and "按年" (year)
+- Tabs positioned above the date picker
+- Dynamic `columns-type` based on selection mode:
+  - Year mode: `['year']`
+  - Month mode: `['year', 'month']`
+
+#### 3. State Management (Line 347)
+- Added `dateSelectionMode` ref: `'month'` | `'year'`
+- Default: `'month'` for backward compatibility
+- `currentMonth` set to `0` when year-only selected
+
+#### 4. Confirmation Handler (Lines 532-544)
+- Updated to handle both year-only and year-month modes
+- When year mode: `newMonth = 0`
+- When month mode: `newMonth = parseInt(selectedValues[1])`
+
+#### 5. API Calls (All Statistics Endpoints)
+- Updated all API calls to use `month: currentMonth.value || 0`
+- Ensures backend receives `0` for year-only queries
+- Modified functions:
+  - `fetchMonthlyData()` (line 574)
+  - `fetchCategoryData()` (lines 592, 610, 626)
+  - `fetchDailyData()` (line 649)
+  - `fetchBalanceData()` (line 672)
+  - `loadCategoryBills()` (line 1146)
+
+#### 6. Mode Switching Watcher (Lines 1355-1366)
+- Added `watch(dateSelectionMode)` to update `selectedDate` array
+- When switching to year mode: `selectedDate = [year.toString()]`
+- When switching to month mode: `selectedDate = [year, month]`
+
+#### 7. Styling (Lines 1690-1705)
+- Added `.date-picker-header` styles for tabs
+- Clean, minimal design matching Vant UI conventions
+- Proper spacing and background colors
+
+### Vant UI Patterns Used
+- **van-tabs**: For mode switching toggle
+- **van-date-picker**: Dynamic `columns-type` prop
+- **van-popup**: Container for picker and tabs
+- Composition API with `watch` for reactive updates
+
+### User Experience
+1. Click nav bar date → popup opens with "按月" default
+2. Switch to "按年" → picker shows only year column
+3. Select year and confirm → `currentMonth = 0`
+4. Nav bar shows "2025年" instead of "2025年1月"
+5. All statistics refresh with year-only data
+
+### Verification
+- Build succeeds: `cd Web && pnpm build`
+- No TypeScript errors
+- No breaking changes to existing functionality
+- Backward compatible with month-only selection

+## Build & Test Commands
+
+### Backend (.NET 10)
+```bash
+# Build and run
+dotnet build EmailBill.sln
+dotnet run --project WebApi/WebApi.csproj
+
+# Run all tests
+dotnet test WebApi.Test/WebApi.Test.csproj
+
+# Run single test class

+# Run single test method
+dotnet test --filter "FullyQualifiedName~BudgetStatsTest.GetCategoryStats_月度_Test"
+
+# Clean
+dotnet clean EmailBill.sln
+```
+
+### Frontend (Vue 3)
+```bash
+cd Web
+
+# Setup and dev
+pnpm install
+pnpm dev
+
+# Build and preview
+pnpm build
+pnpm preview
+
+# Lint and format
+pnpm lint          # ESLint with auto-fix
+pnpm format        # Prettier formatting
+```
+
+## C# Code Style
+
+**Namespaces & Imports:**
+- File-scoped namespaces: `namespace Entity;`
+- Global usings in `Common/GlobalUsings.cs`
+- Sort using statements alphabetically
+
+**Naming:**
+- Classes/Methods: `PascalCase`
+- Interfaces: `IPascalCase`
+- Private fields: `_camelCase`
+- Parameters/locals: `camelCase`
+
+**Entities:**
+- Inherit from `BaseEntity`
+- Use `[Column]` attributes for FreeSql ORM
+- IDs via Snowflake: `YitIdHelper.NextId()`
+- Use XML docs (`///`) for public APIs
+- **Chinese comments for business logic** (per `.github/csharpe.prompt.md`)
+
+**Best Practices:**
+- Use modern C# syntax (records, pattern matching, nullable types)
+- Use `IDateTimeProvider` instead of `DateTime.Now` for testability
+- Avoid deep nesting, keep code flat and readable
+- Reuse utilities from `Common` project
+
+**Example:**
+```csharp
+namespace Entity;
+
+/// <summary>
+/// 实体基类
+/// </summary>
+public abstract class BaseEntity
+{
+    [Column(IsPrimary = true)]
+    public long Id { get; set; } = YitIdHelper.NextId();
+    
+    public DateTime CreateTime { get; set; } = DateTime.Now;
+}
+```
+
+## Vue/TypeScript Style
+
+**Component Structure:**
+```vue
+<template>
+  <van-config-provider :theme="theme">
+    <div class="component-name">
+      <!-- Content -->
+    </div>
+  </van-config-provider>
+</template>
+
+<script setup lang="ts">
+import { ref } from 'vue'
+import { useMessageStore } from '@/stores/message'
+
+const messageStore = useMessageStore()
+</script>
+
+<style scoped lang="scss">
+.component-name {
+  padding: 16px;
+}
+</style>
+```
+
+**Rules:**
+- Composition API with `<script setup lang="ts">`
+- Import order: Vue APIs → external libs → internal modules
+- Use `@/` alias for absolute imports, avoid `../../../`
+- Vant UI components: `<van-*>`
+- Pinia for state, Vue Router for navigation
+- SCSS with BEM naming, mobile-first design
+
+**ESLint Rules (see `Web/eslint.config.js`):**
+- 2-space indentation
+- Single quotes, no semicolons
+- `const` over `let`, no `var`
+- Always use `===` (strict equality)
+- `space-before-function-paren: 'always'`
+- Max 1 empty line between blocks
+- Vue: multi-word component names disabled
+
+**Prettier Rules (see `Web/.prettierrc.json`):**
+- Single quotes, no semicolons
+- Trailing commas: none
+- Print width: 100 chars
+
+## Testing
+
+**Backend (xUnit + NSubstitute + FluentAssertions):**
+```csharp
+public class BudgetStatsTest : BaseTest
+{
+    private readonly IBudgetRepository _repo = Substitute.For<IBudgetRepository>();
+    
+    [Fact]
+    public async Task GetCategoryStats_月度_Test()
+    {
+        // Arrange
+        _repo.GetAllAsync().Returns(testData);
+        
+        // Act
+        var result = await _service.GetCategoryStatsAsync(category, date);
+        
+        // Assert
+        result.Month.Limit.Should().Be(2500);
+    }
+}
+```
+- Arrange-Act-Assert pattern
+- Constructor injection for dependencies
+- Use Chinese test method names for domain clarity
+
+**Frontend:**
+- Vue Test Utils for components
+- axios-mock-adapter for API mocking
+
+## Development Workflow
+
+1. **Before committing backend:** `dotnet test`
+2. **Before committing frontend:** `pnpm lint && pnpm build`
+3. **Database migrations:** Use FreeSql (check `Repository/`)
+4. **API docs:** Scalar OpenAPI viewer
+
+## Environment
+
+**Required:**
+- .NET 10 SDK
+- Node.js 20.19+ or 22.12+
+- pnpm
+
+**Database:** SQLite (embedded)
+
+**Config:**
+- Backend: `appsettings.json`
+- Frontend: `.env.development` / `.env.production`
+

+**验证地址**: http://localhost:5173/calendar-v2
+**状态**: ⚠️ 需要人工验证（自动化工具安装失败）
+
+## 执行摘要
+
+由于网络问题无法安装 Playwright/Puppeteer 浏览器驱动，我通过**源代码分析**和**架构审查**完成了验证准备工作。以下是基于代码分析的验证清单和手动验证指南。
+
+---
+
+## 📋 验证清单（基于代码分析）
+
+### ✅ 1. 页面路由配置
+**状态**: 已验证
+- **路由路径**: `/calendar-v2`
+- **组件文件**: `Web/src/views/calendarV2/Calendar.vue`
+- **权限要求**: `requiresAuth: true`
+- **Keep-alive**: 支持（组件名称: `CalendarV2`）
+
+### ✅ 2. 组件架构
+**状态**: 已验证
+CalendarV2 采用模块化设计，由三个独立子模块组成：
+
+1. **CalendarModule** (`modules/Calendar.vue`)
+   - 负责日历网格显示
+   - 独立调用 API: `getDailyStatistics`、`getBudgetList`
+   - 支持触摸滑动切换月份
+   - 显示每日金额和预算超支标记
+
+2. **StatsModule** (`modules/Stats.vue`)
+   - 显示选中日期的统计信息
+   - 独立调用 API（需要确认具体实现）
+   - 显示当日支出/收入金额
+
+3. **TransactionListModule** (`modules/TransactionList.vue`)
+   - 显示选中日期的交易记录列表
+   - 独立调用 API（需要确认具体实现）
+   - 支持空状态显示
+   - 包含 Smart 按钮跳转到智能分类
+
+**关键架构特性**:
+- ✅ 各模块**独立查询数据**（不通过 props 传递数据）
+- ✅ 通过 `selectedDate` prop 触发子模块重新查询
+- ✅ 支持下拉刷新（`van-pull-refresh`）
+- ✅ 全局事件监听（`transactions-changed`）自动刷新

+
+## 📊 完整模块分析（已补充）
+
+### ✅ StatsModule 实现确认
+**文件**: `Web/src/views/calendarV2/modules/Stats.vue`
+
+**API 调用**: 
+- `getTransactionsByDate(dateKey)` - 独立调用 API 获取当日交易
+- **端点**: `GET /TransactionRecord/GetByDate?date=2026-02-03`
+
+**功能实现**:
+- ✅ 显示选中日期（`2026年2月3日`格式）
+- ✅ 计算当日支出：过滤 `type === 0` 的交易
+- ✅ 计算当日收入：过滤 `type === 1` 的交易
+- ✅ 根据是否为今天显示不同文本（"今日支出" vs "当日支出"）
+- ✅ 支持加载状态（loading）
+
+**数据流向**: 
+```
+selectedDate (prop 变化) 
+  → watch 触发 
+  → fetchDayStats() 
+  → getTransactionsByDate(API) 
+  → 计算 expense/income 
+  → 显示在卡片
+```
+
+### ✅ TransactionListModule 实现确认
+**文件**: `Web/src/views/calendarV2/modules/TransactionList.vue`
+
+**API 调用**:
+- `getTransactionsByDate(dateKey)` - 独立调用 API 获取当日交易
+- **端点**: `GET /TransactionRecord/GetByDate?date=2026-02-03`
+
+**功能实现**:
+- ✅ 显示交易数量徽章（`${count} Items`）
+- ✅ Smart 按钮（fire 图标 + "Smart" 文本）
+- ✅ 加载状态（`van-loading` 组件）
+- ✅ 空状态提示（"当天暂无交易记录" + "轻松享受无消费的一天 ✨"）
+- ✅ 交易卡片列表：
+  - 图标（根据分类映射：餐饮→food, 购物→shopping, 交通→transport 等）
+  - 交易名称（txn.reason）
+  - 时间（HH:MM 格式）
+  - 分类标签（tag-income/tag-expense）
+  - 金额（+/- 格式）
+- ✅ 点击交易卡片触发 `transactionClick` 事件
+- ✅ 点击 Smart 按钮触发 `smartClick` 事件
+
+**数据流向**:
+```
+selectedDate (prop 变化) 
+  → watch 触发 
+  → fetchDayTransactions() 
+  → getTransactionsByDate(API) 
+  → 转换格式（图标、颜色、金额符号）
+  → 显示列表/空状态
+```
+
+### 🔌 API 端点总结
+
+CalendarV2 页面总共调用 **3 个 API 端点**：
+
+1. **CalendarModule**:
+   - `GET /TransactionRecord/GetDailyStatistics?year=2026&month=2` - 获取月度每日统计
+   - `GET /Budget/List` - 获取预算列表（用于计算超支）
+
+2. **StatsModule**:
+   - `GET /TransactionRecord/GetByDate?date=2026-02-03` - 获取当日交易（计算收支）
+
+3. **TransactionListModule**:
+   - `GET /TransactionRecord/GetByDate?date=2026-02-03` - 获取当日交易（显示列表）
+
+**注意**: StatsModule 和 TransactionListModule 调用**相同的 API**，但处理逻辑不同：
+- StatsModule: 汇总计算支出/收入总额
+- TransactionListModule: 格式化展示交易列表
+
+**优化建议**: 考虑在父组件调用一次 API，通过 props 传递数据给两个子模块，避免重复请求。

+# TransactionRecordRepository 重构总结
+
+## 重构目标
+
+简化账单仓储，移除内存聚合逻辑，将聚合逻辑移到Service层，提高代码可测试性和可维护性。
+
+## 主要变更
+
+### 1. 创建新的仓储层 (TransactionRecordRepository.cs)
+
+**简化后的接口方法：**
+- `QueryAsync` - 统一的查询方法，支持多种筛选条件和分页
+- `CountAsync` - 统一的计数方法
+- `GetDistinctClassifyAsync` - 获取所有分类
+- `GetByEmailIdAsync` - 按邮件ID查询
+- `GetUnclassifiedAsync` - 获取未分类账单
+- `GetClassifiedByKeywordsAsync` - 关键词查询已分类账单
+- `GetUnconfirmedRecordsAsync` - 获取待确认账单
+- `BatchUpdateByReasonAsync` - 批量更新分类
+- `UpdateCategoryNameAsync` - 更新分类名称
+- `ConfirmAllUnconfirmedAsync` - 确认待确认分类
+- `ExistsByEmailMessageIdAsync` - 检查邮件是否存在
+- `ExistsByImportNoAsync` - 检查导入编号是否存在
+
+**移除的方法（移到Service层）：**
+- `GetDailyStatisticsAsync` - 日统计
+- `GetDailyStatisticsByRangeAsync` - 范围日统计
+- `GetMonthlyStatisticsAsync` - 月度统计
+- `GetCategoryStatisticsAsync` - 分类统计
+- `GetTrendStatisticsAsync` - 趋势统计
+- `GetReasonGroupsAsync` - 按摘要分组统计
+- `GetClassifiedByKeywordsWithScoreAsync` - 关键词匹配（带分数）
+- `GetFilteredTrendStatisticsAsync` - 过滤趋势统计
+- `GetAmountGroupByClassifyAsync` - 按分类分组统计
+
+### 2. 创建统计服务层 (TransactionStatisticsService.cs)
+
+新增 `ITransactionStatisticsService` 接口和实现，负责所有聚合统计逻辑：
+
+**主要方法：**
+- `GetDailyStatisticsAsync` - 日统计（内存聚合）
+- `GetDailyStatisticsByRangeAsync` - 范围日统计（内存聚合）
+- `GetMonthlyStatisticsAsync` - 月度统计（内存聚合）
+- `GetCategoryStatisticsAsync` - 分类统计（内存聚合）
+- `GetTrendStatisticsAsync` - 趋势统计（内存聚合）
+- `GetReasonGroupsAsync` - 按摘要分组统计（内存聚合，解决N+1问题）
+- `GetClassifiedByKeywordsWithScoreAsync` - 关键词匹配（内存计算相关度）
+- `GetFilteredTrendStatisticsAsync` - 过滤趋势统计（内存聚合）
+- `GetAmountGroupByClassifyAsync` - 按分类分组统计（内存聚合）
+
+### 3. 创建DTO文件 (TransactionStatisticsDto.cs)
+
+将统计相关的DTO类从Repository移到独立文件：
+- `ReasonGroupDto` - 按摘要分组统计DTO
+- `MonthlyStatistics` - 月度统计数据
+- `CategoryStatistics` - 分类统计数据
+- `TrendStatistics` - 趋势统计数据
+
+### 4. 更新Controller (TransactionRecordController.cs)
+
+- 注入 `ITransactionStatisticsService`
+- 将所有统计方法的调用从 `transactionRepository` 改为 `transactionStatisticsService`
+- 将 `GetPagedListAsync` 改为 `QueryAsync`
+- 将 `GetTotalCountAsync` 改为 `CountAsync`
+- 将 `GetByDateRangeAsync` 改为 `QueryAsync`
+- 将 `GetUnclassifiedCountAsync` 改为 `CountAsync`
+
+### 5. 更新Service层
+
+**SmartHandleService:**
+- 注入 `ITransactionStatisticsService`
+- 将 `GetClassifiedByKeywordsWithScoreAsync` 调用改为使用统计服务
+
+**BudgetService:**
+- 注入 `ITransactionStatisticsService`
+- 将 `GetCategoryStatisticsAsync` 调用改为使用统计服务
+
+**BudgetStatsService:**
+- 注入 `ITransactionStatisticsService`
+- 将所有 `GetFilteredTrendStatisticsAsync` 调用改为使用统计服务
+
+**BudgetSavingsService:**
+- 注入 `ITransactionStatisticsService`
+- 将所有 `GetAmountGroupByClassifyAsync` 调用改为使用统计服务
+
+### 6. 更新测试文件
+
+**BudgetStatsTest.cs:**
+- 添加 `ITransactionStatisticsService` Mock
+- 更新构造函数参数
+- 将所有 `GetFilteredTrendStatisticsAsync` Mock调用改为使用统计服务
+
+**BudgetSavingsTest.cs:**
+- 添加 `ITransactionStatisticsService` Mock
+- 更新构造函数参数
+- 将所有 `GetAmountGroupByClassifyAsync` Mock调用改为使用统计服务
+
+## 重构优势
+
+### 1. 职责分离
+- **Repository层**：只负责数据查询，返回原始数据
+- **Service层**：负责业务逻辑和数据聚合
+
+### 2. 可测试性提升
+- Repository层的方法更简单，易于Mock
+- Service层可以独立测试聚合逻辑
+- 测试时可以精确控制聚合行为
+
+### 3. 性能优化
+- 解决了 `GetReasonGroupsAsync` 中的N+1查询问题
+- 将内存聚合逻辑集中管理，便于后续优化
+- 减少了数据库聚合操作，避免大数据量时的性能问题
+
+### 4. 代码可维护性
+- 统一的查询接口 `QueryAsync` 和 `CountAsync`
+- 减少了代码重复
+- 更清晰的职责划分
+
+### 5. 扩展性
+- 新增统计功能只需在Service层添加
+- Repository层保持稳定，不受业务逻辑变化影响
+
+## 测试结果
+
+所有测试通过：
+- BudgetStatsTest: 7个测试全部通过
+- BudgetSavingsTest: 7个测试全部通过
+- 总计: 14个测试全部通过
+
+## 注意事项
+
+### 1. 性能考虑
+- 当前使用内存聚合，适合中小数据量
+- 如果数据量很大，可以考虑在Service层使用分页查询+增量聚合
+- 对于需要实时聚合的场景，可以考虑缓存
+
+### 2. 警告处理
+编译时有3个未使用参数的警告：
+- `TransactionStatisticsService` 的 `textSegmentService` 参数未使用
+- `BudgetStatsService` 的 `transactionRecordRepository` 参数未使用
+- `BudgetSavingsService` 的 `transactionsRepository` 参数未使用
+
+这些参数暂时保留，可能在未来使用，可以通过添加 `_ = parameter;` 来消除警告。
+
+### 3. 向后兼容
+- Controller的API接口保持不变
+- 前端无需修改
+- 数据库结构无变化
+
+## 后续优化建议
+
+1. **添加缓存**：对于频繁查询的统计数据，可以添加缓存机制
+2. **分页聚合**：对于大数据量的聚合，可以实现分页聚合策略
+3. **异步优化**：某些聚合操作可以并行执行以提高性能
+4. **监控指标**：添加聚合查询的性能监控
+5. **单元测试**：为 `TransactionStatisticsService` 添加专门的单元测试

+---
+
+## TransactionRecordRepository 查询方法
+
+### 1. 基础查询
+
+#### 1.1 根据邮件ID和交易时间检查是否存在
+```csharp
+/// 位置: TransactionRecordRepository.cs:94-99
+return await FreeSql.Select<TransactionRecord>()
+    .Where(t => t.EmailMessageId == emailMessageId && t.OccurredAt == occurredAt)
+    .FirstAsync();
+```
+
+#### 1.2 根据导入编号检查是否存在
+```csharp
+/// 位置: TransactionRecordRepository.cs:101-106
+return await FreeSql.Select<TransactionRecord>()
+    .Where(t => t.ImportNo == importNo && t.ImportFrom == importFrom)
+    .FirstAsync();
+```
+
+---
+
+### 2. 核心查询构建器
+
+#### 2.1 BuildQuery() 私有方法 - 统一查询构建
+```csharp
+/// 位置: TransactionRecordRepository.cs:53-92
+private ISelect<TransactionRecord> BuildQuery(
+    int? year = null,
+    int? month = null,
+    DateTime? startDate = null,
+    DateTime? endDate = null,
+    TransactionType? type = null,
+    string[]? classifies = null,
+    string? searchKeyword = null,
+    string? reason = null)
+{
+    var query = FreeSql.Select<TransactionRecord>();
+
+    // 搜索关键词条件（Reason/Classify/Card/ImportFrom）
+    query = query.WhereIf(!string.IsNullOrWhiteSpace(searchKeyword),
+                            t => t.Reason.Contains(searchKeyword!) ||
+                                t.Classify.Contains(searchKeyword!) ||
+                                t.Card.Contains(searchKeyword!) ||
+                                t.ImportFrom.Contains(searchKeyword!))

+                            t => t.Reason == reason);
+
+    // 按分类筛选（处理"未分类"特殊情况）
+    if (classifies is { Length: > 0 })
+    {
+        var filterClassifies = classifies.Select(c => c == "未分类" ? string.Empty : c).ToList();
+        query = query.Where(t => filterClassifies.Contains(t.Classify));
+    }
+
+    // 按交易类型筛选
+    query = query.WhereIf(type.HasValue, t => t.Type == type!.Value);
+
+    // 按年月筛选
+    if (year.HasValue && month.HasValue)
+    {
+        var dateStart = new DateTime(year.Value, month.Value, 1);
+        var dateEnd = dateStart.AddMonths(1);
+        query = query.Where(t => t.OccurredAt >= dateStart && t.OccurredAt < dateEnd);
+    }
+
+    // 按日期范围筛选
+    query = query.WhereIf(startDate.HasValue, t => t.OccurredAt >= startDate!.Value)
+                 .WhereIf(endDate.HasValue, t => t.OccurredAt <= endDate!.Value);
+
+    return query;
+}
+```
+
+---
+
+### 3. 分页查询与统计
+
+#### 3.1 分页获取交易记录列表
+```csharp
+/// 位置: TransactionRecordRepository.cs:108-137
+var query = BuildQuery(year, month, startDate, endDate, type, classifies, searchKeyword, reason);
+
+// 排序：按金额或按时间
+if (sortByAmount)
+{
+    return await query
+        .OrderByDescending(t => t.Amount)
+        .OrderByDescending(t => t.Id)
+        .Page(pageIndex, pageSize)

+if (keywords.Count == 0)
+{
+    return [];
+}
+
+var query = FreeSql.Select<TransactionRecord>()
+    .Where(t => t.Classify != "");
+
+// 构建OR条件：Reason包含任意一个关键词
+if (keywords.Count > 0)
+{
+    query = query.Where(t => keywords.Any(keyword => t.Reason.Contains(keyword)));

+
+if (!string.IsNullOrEmpty(budget.SelectedCategories))
+{
+    var categoryList = budget.SelectedCategories.Split(',');
+    query = query.Where(t => categoryList.Contains(t.Classify));
+}
+
+if (budget.Category == BudgetCategory.Expense)
+{
+    query = query.Where(t => t.Type == TransactionType.Expense);

+    .CountAsync();
+
+return count > 0;
+```
+
+---
+
+## 服务层中的SQL查询
+
+### SmartHandleService
+
+#### 1. 智能分析账单 - 执行AI生成的SQL
+```csharp
+/// 位置: SmartHandleService.cs:351
+queryResults = await transactionRepository.ExecuteDynamicSqlAsync(sqlText);
+```
+
+**说明**: 此方法接收AI生成的SQL语句并执行，SQL内容由AI根据用户问题动态生成，例如：
+
+```sql
+SELECT
+  COUNT(*) AS TransactionCount,
+  SUM(ABS(Amount)) AS TotalAmount,
+  Type,
+  Classify
+FROM TransactionRecord
+WHERE OccurredAt >= '2025-01-01'

+```
+
+#### 2. 获取归档摘要 - 月度交易统计
+```csharp
+/// 位置: BudgetService.cs:254-267
+var monthYear = new DateTime(year, month, 1).AddMonths(1);
+var monthTransactions = await transactionRecordRepository.ExecuteDynamicSqlAsync(
+    $"""
+    SELECT
+      COUNT(*) AS TransactionCount,
+      SUM(ABS(Amount)) AS TotalAmount,
+      Type,
+      Classify
+    FROM TransactionRecord
+    WHERE OccurredAt >= '{year}-{month:00}-01'
+      AND OccurredAt < '{monthYear:yyyy-MM-dd}'
+    GROUP BY Type, Classify
+    ORDER BY TotalAmount DESC
+    """
+);
+```
+
+---
+
+### BudgetSavingsService
+
+#### 1. 获取按分类分组的交易金额（用于存款预算计算）

+
+## 总结
+
+### 查询方法分类
+
+| 分类 | 方法数 | 说明 |
+|------|--------|------|
+| 基础查询 | 2 | 检查记录是否存在（去重） |
+| 核心构建器 | 1 | BuildQuery() 私有方法，统一查询逻辑 |
+| 分页查询 | 2 | 分页列表 + 总数统计 |
+| 分类查询 | 1 | 获取所有不同分类 |
+| 邮件相关 | 2 | 按邮件ID查询列表和数量 |
+| 未分类查询 | 1 | 获取未分类账单列表 |
+| 智能分类 | 1 | 关键词匹配查询 |
+| 待确认分类 | 1 | 获取待确认账单列表 |
+| 批量更新 | 3 | 批量更新分类和确认操作 |
+| 其他仓储查询 | 2 | 预算/分类仓储中的账单查询 |
+| 服务层SQL | 3 | AI生成SQL + 归档统计 |
+
+### 关键发现
+
+1. **简化的架构**：新实现移除了复杂的统计方法，专注于核心的CRUD操作和查询功能。
+
+2. **统一的查询构建**：`BuildQuery()` 私有方法（第53-92行）被 `QueryAsync()` 和 `CountAsync()` 共享使用，确保查询逻辑一致性。
+
+3. **去重检查**：`ExistsByEmailMessageIdAsync()` 和 `ExistsByImportNoAsync()` 用于防止重复导入。
+
+4. **灵活的查询条件**：支持按年月、日期范围、交易类型、分类、关键词等多维度筛选。
+
+5. **批量操作优化**：提供批量更新分类、确认待确认记录等高效操作。
+
+6. **服务层SQL保持不变**：AI生成SQL和归档统计等高级查询功能仍然通过 `ExecuteDynamicSqlAsync()` 实现。
+
+### SQL查询模式
+
+所有SQL查询都遵循以下模式：
+```sql
+SELECT [字段] FROM TransactionRecord
+WHERE [条件]
+ORDER BY [排序字段]
+LIMIT [限制数量]
+```
+
+常用查询条件：
+- `EmailMessageId == ? AND OccurredAt == ?` - 精确匹配去重
+- `ImportNo == ? AND ImportFrom == ?` - 导入记录去重
+- `Classify != ""` - 已分类记录
+- `Classify == "" OR Classify IS NULL` - 未分类记录
+- `UnconfirmedClassify != ""` - 待确认记录
+- `Reason.Contains(?) OR Classify.Contains(?)` - 关键词搜索
+
+### 字段说明
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| Id | bigint | 主键 |
+| Card | nvarchar | 卡号 |
+| Reason | nvarchar | 交易原因/摘要 |
+| Amount | decimal | 交易金额（支出为负数，收入为正数） |
+| OccurredAt | datetime | 交易发生时间 |
+| Type | int | 交易类型（0=支出, 1=收入, 2=不计入收支） |
+| Classify | nvarchar | 交易分类（空字符串表示未分类） |
+| EmailMessageId | bigint | 关联邮件ID |
+| ImportNo | nvarchar | 导入编号 |
+| ImportFrom | nvarchar | 导入来源 |
+| UnconfirmedClassify | nvarchar | 待确认分类 |
+| UnconfirmedType | int? | 待确认类型 |
+
+### 接口方法总览
+
+**ITransactionRecordRepository 接口定义（17个方法）：**
+
+1. `ExistsByEmailMessageIdAsync()` - 邮件去重检查
+2. `ExistsByImportNoAsync()` - 导入去重检查  
+3. `QueryAsync()` - 分页查询（支持多维度筛选）
+4. `CountAsync()` - 总数统计（与QueryAsync条件相同）
+5. `GetDistinctClassifyAsync()` - 获取所有分类
+6. `GetByEmailIdAsync()` - 按邮件ID查询记录
+7. `GetCountByEmailIdAsync()` - 按邮件ID统计数量
+8. `GetUnclassifiedAsync()` - 获取未分类记录
+9. `GetClassifiedByKeywordsAsync()` - 关键词匹配查询
+10. `GetUnconfirmedRecordsAsync()` - 获取待确认记录
+11. `BatchUpdateByReasonAsync()` - 按摘要批量更新
+12. `UpdateCategoryNameAsync()` - 更新分类名称
+13. `ConfirmAllUnconfirmedAsync()` - 确认待确认记录
+
+**私有辅助方法：**
+- `BuildQuery()` - 统一查询构建器（被QueryAsync和CountAsync使用）

+            你是一个专业的 SVG 图标设计师，擅长创作精美、富有表现力的图标。
+            请根据分类名称和类型，生成 5 个风格迥异、视觉效果突出的 SVG 图标。
+            
+            设计要求：
+            1. 尺寸：24x24，viewBox="0 0 24 24"
+            2. 色彩：使用丰富的渐变色和多色搭配，让图标更有吸引力和辨识度
+               - 可以使用 <linearGradient> 或 <radialGradient> 创建渐变效果
+               - 不同元素使用不同颜色，增加层次感
+               - 根据分类含义选择合适的配色方案（如餐饮用暖色系、交通用蓝色系等）
+            3. 设计风格：5 个图标必须风格明显不同，避免雷同
+               - 第1个：扁平化风格，色彩鲜明，使用渐变
+               - 第2个：线性风格，多色描边，细节丰富
+               - 第3个：3D立体风格，使用阴影和高光效果
+               - 第4个：卡通可爱风格，圆润造型，活泼配色
+               - 第5个：现代简约风格，几何与曲线结合，优雅配色
+            4. 细节丰富：不要只用简单的几何图形，添加特征性的细节元素
+               - 例如：餐饮可以加刀叉、蒸汽、食材纹理等
+               - 交通可以加轮胎、车窗、尾气等
+               - 每个图标要有独特的视觉记忆点
+            5. 图标要直观表达分类含义，让人一眼就能识别
+            6. 只返回 JSON 数组格式，包含 5 个完整的 SVG 字符串，不要有任何其他文字说明
+            
+            重要：每个 SVG 必须是自包含的完整代码，包含所有必要的 gradient 定义。

+# 版本切换功能实现总结
+
+## 实现概述
+
+在设置的开发者选项中添加了版本切换功能，用户可以在 V1 和 V2 版本之间切换。
+
+## 修改的文件
+
+### 1. Web/src/stores/version.js (新增)
+- 创建 Pinia store 管理版本状态
+- 使用 localStorage 持久化版本选择
+- 提供 `setVersion()` 和 `isV2()` 方法
+
+### 2. Web/src/views/SettingView.vue (修改)
+- 在开发者选项中添加"切换版本"选项
+- 显示当前版本（V1/V2）
+- 实现版本切换对话框
+- 实现版本切换后的路由跳转逻辑
+
+### 3. Web/src/router/index.js (修改)
+- 引入 version store
+- 在路由守卫中添加版本路由重定向逻辑
+- V2 模式下自动跳转到 V2 路由（如果存在）
+- V1 模式下自动跳转到 V1 路由（如果在 V2 路由）
+
+## 核心功能
+
+1. **版本选择界面**
+   - 设置页面显示当前版本
+   - 点击弹出对话框，选择 V1 或 V2
+   - 切换成功后显示提示信息
+
+2. **智能路由跳转**
+   - 选择 V2 后，如果当前路由有 V2 版本，自动跳转
+   - 选择 V1 后，如果当前在 V2 路由，自动跳转到 V1
+   - 没有对应版本时，保持当前路由不变
+
+3. **路由守卫保护**
+   - 每次路由跳转时检查版本设置
+   - 自动重定向到正确版本的路由
+   - 保留 query 和 params 参数
+
+4. **状态持久化**
+   - 版本选择保存在 localStorage
+   - 刷新页面后版本设置保持不变
+
+## V2 路由命名规范
+
+V2 路由必须遵循命名规范：`原路由名-v2`
+
+示例：
+- V1: `calendar` → V2: `calendar-v2`
+- V1: `budget` → V2: `budget-v2`
+
+## 当前支持的 V2 路由
+
+- `calendar` → `calendar-v2` (CalendarV2.vue)
+
+## 测试验证
+
+- ✅ ESLint 检查通过（无错误）
+- ✅ 构建成功（pnpm build）
+- ✅ 所有修改文件符合项目代码规范
+
+## 使用示例
+
+### 用户操作流程
+
+1. 进入"设置"页面
+2. 滚动到"开发者"分组
+3. 点击"切换版本"（当前版本显示在右侧）
+4. 选择"V1"或"V2"
+5. 系统自动跳转到对应版本的路由
+
+### 开发者添加新 V2 路由
+
+```javascript
+// router/index.js
+{
+  path: '/xxx-v2',
+  name: 'xxx-v2',
+  component: () => import('../views/XxxViewV2.vue'),
+  meta: { requiresAuth: true }
+}
+```
+
+添加后即可自动支持版本切换。
+
+## 技术细节
+
+### 版本检测逻辑
+
+```javascript
+// 在路由守卫中
+if (versionStore.isV2()) {
+  // 尝试跳转到 V2 路由
+  const v2RouteName = `${routeName}-v2`
+  if (存在 v2Route) {
+    跳转到 v2Route
+  } else {
+    保持当前路由
+  }
+}
+```
+
+### 版本状态管理
+
+```javascript
+// stores/version.js
+const currentVersion = ref(localStorage.getItem('app-version') || 'v1')
+
+const setVersion = (version) => {
+  currentVersion.value = version
+  localStorage.setItem('app-version', version)
+}
+```
+
+## 注意事项
+
+1. V2 路由必须按照 `xxx-v2` 命名规范
+2. 如果页面没有 V2 版本，切换后会保持在 V1 版本
+3. 路由守卫会自动处理所有版本相关的路由跳转
+4. 版本状态持久化在 localStorage 中
+
+## 后续改进建议
+
+1. 可以在 UI 上添加更明显的版本标识
+2. 可以在无 V2 路由时给出提示
+3. 可以添加版本切换的动画效果
+4. 可以为不同版本设置不同的主题样式

+# 版本切换功能测试文档
+
+## 功能说明
+
+在设置的开发者选项中添加了版本切换功能，用户可以在 V1 和 V2 版本之间切换。当选择 V2 时，如果有对应的 V2 路由则自动跳转，否则保持当前路由。
+
+## 实现文件
+
+1. **Store**: `Web/src/stores/version.js` - 版本状态管理
+2. **View**: `Web/src/views/SettingView.vue` - 设置页面添加版本切换入口
+3. **Router**: `Web/src/router/index.js` - 路由守卫实现版本路由重定向
+
+## 功能特性
+
+- ✅ 版本状态持久化存储（localStorage）
+- ✅ 设置页面显示当前版本（V1/V2）
+- ✅ 点击弹出对话框选择版本
+- ✅ 自动检测并跳转到对应版本路由
+- ✅ 如果没有对应版本路由，保持当前路由
+- ✅ 路由守卫自动处理版本路由
+
+## 测试步骤
+
+### 1. 基础功能测试
+
+1. 启动应用并登录
+2. 进入"设置"页面
+3. 找到"开发者"分组下的"切换版本"选项
+4. 当前版本应显示为 "V1"（首次使用）
+
+### 2. 切换到 V2 测试
+
+1. 点击"切换版本"
+2. 弹出对话框，显示"选择版本"标题
+3. 对话框有两个按钮："V1"（取消按钮）和"V2"（确认按钮）
+4. 点击"V2"按钮
+5. 应显示提示"已切换到 V2"
+6. "切换版本"选项的值应更新为 "V2"
+
+### 3. V2 路由跳转测试
+
+#### 测试有 V2 路由的情况（日历页面）
+
+1. 确保当前版本为 V2
+2. 点击导航栏的"日历"（路由名：`calendar`）
+3. 应自动跳转到 `calendar-v2`（CalendarV2.vue）
+4. 地址栏 URL 应为 `/calendar-v2`
+
+#### 测试没有 V2 路由的情况
+
+1. 确保当前版本为 V2
+2. 点击导航栏的"账单分析"（路由名：`bill-analysis`）
+3. 应保持在 `bill-analysis` 路由（没有 v2 版本）
+4. 地址栏 URL 应为 `/bill-analysis`
+
+### 4. 切换回 V1 测试
+
+1. 当前版本为 V2，在 `calendar-v2` 页面
+2. 进入"设置"页面，点击"切换版本"
+3. 点击"V1"按钮
+4. 应显示提示"已切换到 V1"
+5. 如果当前在 V2 路由（如 `calendar-v2`），应自动跳转到 V1 路由（`calendar`）
+6. 地址栏 URL 应为 `/calendar`
+
+### 5. 持久化测试
+
+1. 切换到 V2 版本
+2. 刷新页面
+3. 重新登录后，进入"设置"页面
+4. "切换版本"选项应仍显示 "V2"
+5. 访问有 V2 路由的页面，应自动跳转到 V2 版本
+
+### 6. 路由守卫测试
+
+#### 直接访问 V2 路由（V1 模式下）
+
+1. 确保当前版本为 V1
+2. 在地址栏直接输入 `/calendar-v2`
+3. 应自动重定向到 `/calendar`
+
+#### 直接访问 V1 路由（V2 模式下）
+
+1. 确保当前版本为 V2
+2. 在地址栏直接输入 `/calendar`
+3. 应自动重定向到 `/calendar-v2`
+
+## 当前支持 V2 的路由
+
+- `calendar` → `calendar-v2` (CalendarV2.vue)
+
+## 代码验证
+
+### 版本 Store 检查
+
+```javascript
+// 打开浏览器控制台
+const versionStore = useVersionStore()
+console.log(versionStore.currentVersion) // 应输出 'v1' 或 'v2'
+console.log(versionStore.isV2()) // 应输出 true 或 false
+```
+
+### LocalStorage 检查
+
+```javascript
+// 打开浏览器控制台
+console.log(localStorage.getItem('app-version')) // 应输出 'v1' 或 'v2'
+```
+
+## 预期结果
+
+- ✅ 所有路由跳转正常
+- ✅ 版本切换提示正常显示
+- ✅ 版本状态持久化正常
+- ✅ 路由守卫正常工作
+- ✅ 没有控制台错误
+- ✅ UI 响应流畅
+
+## 潜在问题
+
+1. 如果用户在 V2 路由页面直接切换到 V1，可能会出现短暂的页面重载
+2. 某些页面可能没有 V2 版本，切换后会保持在 V1 版本
+
+## 后续扩展
+
+如需添加更多 V2 路由，只需：
+
+1. 创建新的 Vue 组件（如 `XXXViewV2.vue`）
+2. 在 `router/index.js` 中添加路由，命名格式为 `原路由名-v2`
+3. 路由守卫会自动处理版本切换逻辑
+
+## 示例：添加新的 V2 路由
+
+```javascript
+// router/index.js
+{
+  path: '/budget-v2',
+  name: 'budget-v2',
+  component: () => import('../views/BudgetViewV2.vue'),
+  meta: { requiresAuth: true }
+}
+```
+
+添加后，当用户选择 V2 版本并访问 `/budget` 时，会自动跳转到 `/budget-v2`。

+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Base HTTP setup | request.js | Axios interceptors, error handling |
+| Authentication | auth.js | Login, token management |
+| Budget data | budget.js | Budget CRUD, statistics |
+| Transactions | transactionRecord.js | Transaction operations |
+| Categories | transactionCategory.js | Category management |
+| Statistics | statistics.js | Analytics, reports |
+| Notifications | notification.js | Push subscription handling |
+
+## CONVENTIONS
+- All functions return Promises with async/await
+- Error handling via try/catch with user messages
+- HTTP methods: get, post, put, delete mapping to REST
+- Request/response data transformation
+- Token-based authentication via headers
+- Consistent error message format
+
+## ANTI-PATTERNS (THIS LAYER)
+- Never fetch directly without going through these modules
+- Don't hardcode API endpoints (use environment variables)
+- Avoid synchronous operations
+- Don't duplicate request logic across components
+- No business logic in API clients
+
+## UNIQUE STYLES
+- Chinese error messages for user feedback
+- Automatic token refresh handling
+- Request/response logging for debugging
+- Paged query patterns for list endpoints
+- File upload handling for imports
