+# 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

+dotnet run --project WebApi/WebApi.csproj
+
+# Run all tests
+dotnet test WebApi.Test/WebApi.Test.csproj

+
+# 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`
+
+## Critical Guidelines (from `.github/csharpe.prompt.md`)
+
+- 优先使用新C#语法 (Use modern C# syntax)
+- 优先使用中文注释 (Prefer Chinese comments for business logic)
+- 优先复用已有方法 (Reuse existing methods)
+- 不要深嵌套代码 (Avoid deep nesting)
+- 保持代码简洁易读 (Keep code clean and readable)

+# 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

+# REPOSITORY LAYER KNOWLEDGE BASE
+
+**Generated:** 2026-01-28
+**Parent:** EmailBill/AGENTS.md
+
+## OVERVIEW
+Data access layer using FreeSql with BaseRepository pattern and global usings.
+
+## STRUCTURE
+```
+Repository/
+├── BaseRepository.cs           # Generic repository base
+├── GlobalUsings.cs            # Common imports
+├── BudgetRepository.cs         # Budget data access
+├── TransactionRecordRepository.cs # Transaction data access
+├── EmailMessageRepository.cs   # Email data access
+└── TransactionStatisticsDto.cs # Statistics DTOs
+```
+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Base patterns | BaseRepository.cs | Generic CRUD operations |
+| Budget data | BudgetRepository.cs | Budget queries and updates |
+| Transaction data | TransactionRecordRepository.cs | Financial data access |
+| Email data | EmailMessageRepository.cs | Email processing storage |
+| Statistics | TransactionStatisticsDto.cs | Data transfer objects |
+
+## CONVENTIONS
+- Inherit from BaseRepository<T> for all repositories
+- Use GlobalUsings.cs for shared imports
+- Async/await pattern for all database operations
+- Method names: GetAllAsync, GetByIdAsync, InsertAsync, UpdateAsync
+- Return domain entities, not DTOs (except in query results)
+
+## ANTI-PATTERNS (THIS LAYER)
+- Never return anonymous types from methods
+- Don't expose FreeSql ISelect directly
+- Avoid business logic in repositories
+- No synchronous database calls
+- Don't mix data access with service logic
+
+## UNIQUE STYLES
+- Generic constraints: where T : BaseEntity
+- Fluent query building with FreeSql extension methods
+- Paged query patterns for large datasets

+
+## 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!))
+                .WhereIf(!string.IsNullOrWhiteSpace(reason),
+                            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)
+        .ToListAsync();
+}
+
+return await query
+    .OrderByDescending(t => t.OccurredAt)
+    .OrderByDescending(t => t.Id)

+    .OrderByDescending(t => t.OccurredAt)
+    .Page(1, pageSize)
+    .ToListAsync();
+```
+
+---
+
+### 6. 智能分类相关查询
+
+#### 6.1 根据关键词查询已分类的账单
+```csharp
+/// 位置: TransactionRecordRepository.cs:185-204
+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)));
+}
+
+return await query

+return await FreeSql.Update<TransactionRecord>()
+    .Set(a => a.Classify, newName)
+    .Where(a => a.Classify == oldName && a.Type == type)
+    .ExecuteAffrowsAsync();
+```
+
+#### 8.3 确认待确认的分类
+```csharp
+/// 位置: TransactionRecordRepository.cs:231-241
+return await FreeSql.Update<TransactionRecord>()

+
+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);
+}
+else if (budget.Category == BudgetCategory.Income)
+{
+    query = query.Where(t => t.Type == TransactionType.Income);
+}
+
+return await query.SumAsync(t => t.Amount);
+```
+
+---
+
+### TransactionCategoryRepository
+
+#### 1. 检查分类是否被使用
+```csharp

+    .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'

+GROUP BY Type, Classify
+ORDER BY TotalAmount DESC
+```
+
+---
+
+### BudgetService
+
+#### 1. 获取归档摘要 - 年度交易统计
+```csharp
+/// 位置: BudgetService.cs:239-252
+var yearTransactions = await transactionRecordRepository.ExecuteDynamicSqlAsync(
+    $"""
+    SELECT
+      COUNT(*) AS TransactionCount,
+      SUM(ABS(Amount)) AS TotalAmount,
+      Type,
+      Classify
+    FROM TransactionRecord
+    WHERE OccurredAt >= '{year}-01-01'
+      AND OccurredAt < '{year + 1}-01-01'
+    GROUP BY Type, Classify
+    ORDER BY TotalAmount DESC
+    """
+);
+```
+
+#### 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）
+```csharp

+
+## 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）

+
+## ANTI-PATTERNS (THIS LAYER)
+- Never access database directly (use repositories)
+- Don't return domain entities to controllers (use DTOs)
+- Avoid long-running operations in main thread
+- No hardcoded configuration values
+- Don't mix service responsibilities
+
+## UNIQUE STYLES
+- Email parsing with multiple format handlers
+- Background job patterns with error handling
+- Configuration models with validation attributes
+- Service composition patterns

+            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。

+## OVERVIEW
+Axios-based HTTP client modules for backend API integration with request/response interceptors.
+
+## STRUCTURE
+```

+
+## 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

+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Budget management | BudgetView.vue | Main budget interface |
+| Transactions | TransactionsRecord.vue | CRUD operations |
+| Statistics | StatisticsView.vue | Charts, analytics |
+| Classification | Classification* | Transaction categorization |
+| Authentication | LoginView.vue | User login flow |
+| Settings | SettingView.vue | App configuration |
+| Email features | EmailRecord.vue | Email integration |
+
+## CONVENTIONS
+- Vue 3 Composition API with `<script setup lang="ts">`
+- Vant UI components: `<van-*>`
+- Mobile-first responsive design
+- SCSS with BEM naming convention
+- Pinia for state management
+- Vue Router for navigation
+
+## ANTI-PATTERNS (THIS LAYER)
+- Never use Options API (always Composition API)
+- Don't access APIs directly (use api/ modules)
+- Avoid inline styles (use SCSS modules)
+- No synchronous API calls
+- Don't mutate props directly
+
+## UNIQUE STYLES
+- Chinese interface labels for business concepts
+- Mobile-optimized layouts with Vant components
+- Integration with backend API via api/ modules
+- Real-time data updates via Pinia stores
+- Gesture interactions for mobile users

+
+## WHERE TO LOOK
+| Task | Location | Notes |
+|------|----------|-------|
+| Authentication | AuthController.cs | JWT login, token refresh |
+| Budget APIs | BudgetController.cs | Budget CRUD, statistics |
+| Transaction APIs | TransactionRecordController.cs | Financial transactions |
+| Email APIs | EmailMessageController.cs | Email processing |
+| DTO patterns | Dto/ | Request/response models |
+| Standard responses | BaseResponse.cs, PagedResponse.cs | Consistent API format |
+
+## CONVENTIONS
+- Controllers inherit from ControllerBase
+- Route attributes: [ApiController], [Route("api/[controller]")]
+- All actions return Task<IActionResult> or Task<BaseResponse<T>>
+- Use DTOs for all request/response data
+- HTTP verb attributes: [HttpGet], [HttpPost], [HttpPut], [HttpDelete]
+- Validation via model state and attributes
+
+## ANTI-PATTERNS (THIS LAYER)
+- Never return domain entities directly
+- Don't access repositories from controllers (use services)
+- Avoid business logic in controllers
+- No synchronous I/O operations
+- Don't skip authentication/authorization where needed
+
+## UNIQUE STYLES
+- BaseResponse<T> wrapper for consistent API format
+- PagedResponse<T> for list endpoints
+- Chinese error messages for user-facing errors
+- JWT-based authentication patterns
+- Swagger/OpenAPI documentation via attributes
