Subject: [PATCH] feat: remove V1 calendar/budget/stats modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 删除 V1 前端页面 (CalendarView, BudgetView, statisticsV1)
- 移除 V1 路由配置 (/calendar, /budget, /)
- 清理路由守卫中的 V1 版本切换逻辑
- 移除设置页面中的版本切换功能
- 更新底部导航和登录重定向到 V2 路由
- 移除 App.vue 中 V1 页面的缓存配置
- 删除后端 TransactionRecordController.GetDailyStatisticsAsync (Obsolete)
- 删除 TransactionStatisticsController.GetBalanceStatisticsAsync
- 保留 V2 仍在使用的共享 API (GetUncoveredCategories, GetArchiveSummary, GetDailyStatistics)
- 保留 V2 使用的全局事件监听机制
- 所有测试通过 (210/210)

Breaking Change: V1 API 端点和路由将不可用

+## Context
+
+EmailBill 项目在早期开发了 V1 版本的日历、统计、预算三大核心功能模块。随着业务迭代，V2 版本已经重构并稳定运行，提供了更优的用户体验和代码架构。当前代码库中同时维护 V1 和 V2 两套实现，导致：
+
+1. **代码冗余**: 前端包含 `CalendarView.vue`, `BudgetView.vue`, `statisticsV1/Index.vue` 等页面，后端包含多个仅服务于 V1 的 API 端点
+2. **维护成本**: 任何共享组件或数据模型的变更需要同时考虑 V1 和 V2 的兼容性
+3. **认知负担**: 新开发者需要理解两套架构，增加了上手难度
+4. **测试负担**: 需要维护两套测试用例，且部分测试已失效
+
+### 当前状态
+- V2 版本已完成功能对齐，用户已逐步迁移
+- V1 相关 API 端点部分已标记 `[Obsolete]` (如 `TransactionRecordController.GetDailyStatisticsAsync`)
+- 路由守卫中包含 V1/V2 版本切换逻辑
+
+### 约束条件
+- **不能影响 V2 功能**: 必须保证 V2 页面完全正常运行
+- **共享组件不能删除**: `TransactionList`, `TransactionDetail`, `PopupContainer` 等组件被 V2 使用
+- **Repository 层不能动**: V1 和 V2 共用相同的数据访问层
+- **需要手动测试**: 删除后必须打开 V2 页面验证功能完整性
+
+### 利益相关者
+- **开发团队**: 减少维护负担，简化架构
+- **测试团队**: 减少测试用例数量
+- **最终用户**: 无感知（已迁移到 V2）
+
+---
+
+## Goals / Non-Goals
+
+### Goals
+1. **完全移除 V1 代码**: 删除所有 V1 专用的页面、API、Service 方法
+2. **保持 V2 功能完整**: 确保删除操作不影响 V2 版本的任何功能
+3. **清理路由配置**: 移除 V1 路由和版本切换逻辑
+4. **验证功能正常**: 通过手动测试验证 V2 页面能正常打开和使用
+
+### Non-Goals
+1. **不修改 Repository 层**: V2 继续使用现有的 Repository，不进行任何修改
+2. **不修改数据库**: 不涉及数据迁移或表结构变更
+3. **不重构 V2 代码**: 仅删除 V1 代码，不对 V2 进行任何优化或重构
+4. **不移除共享组件**: 即使组件原本为 V1 开发，只要 V2 在用就保留
+5. **不更新文档**: API 文档和用户文档的更新不在本次变更范围内
+
+---
+
+## Decisions
+
+### Decision 1: 采用自底向上的删除顺序 (Backend → Frontend)
+
+**选择**: 先删除后端 Service/Application → 再删除 Controller → 最后删除前端页面和路由
+
+**理由**:
+- **依赖方向**: 前端依赖后端 API，先删除底层可以避免悬挂引用
+- **验证便利**: 删除后端接口后，前端调用会立即报 404，易于发现遗漏
+- **回滚简单**: 如果出问题，可以快速恢复后端接口，前端暂时保留也不影响
+
+**备选方案 (未选择)**:
+- **自顶向下 (Frontend → Backend)**: 先删除前端页面，可能导致后端接口成为"僵尸代码"难以发现
+- **同步删除**: 一次性删除所有层，风险较高且难以定位问题
+
+---
+
+### Decision 2: 通过代码搜索确认 V1 专用性
+
+**选择**: 对每个待删除的方法/接口进行全局搜索，确认仅被 V1 页面调用
+
+**搜索关键字**:
+- 前端页面: `CalendarView.vue`, `BudgetView.vue`, `statisticsV1/Index.vue`
+- API 方法: `GetDailyStatistics`, `GetUncoveredCategories`, `GetArchiveSummary`, `GetBalanceStatistics`
+- 路由: `/calendar`, `/budget`, `name: 'statistics'`
+
+**验证标准**:
+- 如果搜索结果仅出现在以上三个页面中 → 可以安全删除
+- 如果出现在其他文件中 → 标记为"需保留"或"需进一步分析"
+
+**理由**:
+- **准确性**: 避免误删 V2 依赖的代码
+- **可追溯**: 搜索结果可作为删除依据留存
+
+---
+
+### Decision 3: 保留共享组件，即使其仅在 V1 中被直接使用
+
+**选择**: 保留 `TransactionList`, `TransactionDetail`, `PopupContainer`, `SmartClassifyButton` 等组件
+
+**判断依据**:
+- 通过搜索确认这些组件在 V2 页面中有引用
+- 即使组件内部包含 V1 特定逻辑（如全局事件监听），也不在本次变更中修改
+
+**理由**:
+- **最小化风险**: 删除共享组件可能导致 V2 功能异常
+- **职责分离**: 组件优化应作为独立的重构任务，不在本次删除范围内
+
+---
+
+### Decision 4: 移除全局事件监听 (条件性)
+
+**选择**: 如果全局事件 (`transaction-deleted`, `transactions-changed`) **仅在 V1 页面中监听**，则移除事件触发代码
+
+**验证流程**:
+1. 搜索 `window.addEventListener('transaction-deleted')`
+2. 确认监听器仅在 `CalendarView.vue` 和 `statisticsV1/Index.vue` 中注册
+3. 搜索 `window.dispatchEvent(new Event('transaction-deleted'))`
+4. 如果触发位置在共享组件中（如 `TransactionDetail.vue`），检查该组件是否被 V2 使用
+   - 如果被 V2 使用 → 保留事件触发代码（即使 V1 删除后无人监听）
+   - 如果仅 V1 使用 → 删除事件触发代码
+
+**理由**:
+- **保守策略**: 优先保证 V2 功能不受影响
+- **技术债务**: 遗留的无用事件触发代码可作为后续清理任务
+
+---
+
+### Decision 5: 采用手动测试验证 V2 功能
+
+**选择**: 删除完成后，手动打开以下 V2 页面并验证核心功能
+
+**测试清单**:
+1. **统计 V2** (`/statistics-v2`):
+   - 月度统计数据正常加载
+   - 分类统计饼图正常渲染
+   - 日度统计折线图正常渲染
+   - 交易列表正常展示和滚动加载
+2. **预算 V2** (`/budget-v2`):
+   - 预算列表正常加载
+   - 分类统计（月度+年度）正常显示
+   - 预算创建/编辑/删除功能正常
+   - 存款预算导航和显示正常
+3. **日历 V2** (`/calendar-v2`):
+   - 日历视图正常渲染
+   - 日期选择和统计数据加载正常
+   - 交易详情查看和编辑正常
+
+**理由**:
+- **V2 无单元测试覆盖**: 当前项目主要测试集中在后端，前端缺少自动化测试
+- **快速反馈**: 手动测试可以在 10 分钟内完成所有关键路径验证
+- **用户体验保证**: 确保最终用户不会遇到功能异常
+
+**备选方案 (未选择)**:
+- **仅依赖编译检查**: 无法发现运行时错误（如路由配置错误）
+- **编写自动化测试**: 时间成本过高，且本次变更不涉及逻辑修改
+
+---
+
+## Risks / Trade-offs
+
+### Risk 1: 误删 V2 依赖的代码
+**表现**: 删除后端接口或前端方法，导致 V2 页面调用失败
+
+**缓解措施**:
+- 采用 Decision 2 的搜索验证流程，确保每个删除操作都经过确认
+- 先删除后端 Service 层，观察前端是否有新的 404 错误
+- 使用 Git 进行版本控制，支持快速回滚
+
+**残留影响**:
+- 如果 V2 通过动态路由或字符串拼接调用接口，静态搜索可能遗漏
+
+---
+
+### Risk 2: 共享组件包含 V1 特定逻辑但未被清理
+**表现**: 保留的组件中包含 V1 特定的条件判断或事件监听，成为"死代码"
+
+**缓解措施**:
+- 标记为 Non-Goal，不在本次清理范围内
+- 在任务清单中添加"后续优化"任务，记录需要清理的组件列表
+
+**残留影响**:
+- 代码库中保留少量无用代码，但不影响功能正确性
+
+---
+
+### Risk 3: 路由守卫中遗留 V1 相关逻辑
+**表现**: 删除 V1 路由后，`router/index.js` 或 `useVersionStore` 中仍有版本切换逻辑
+
+**缓解措施**:
+- 在任务清单中明确包含"清理路由守卫"任务
+- 搜索 `isV2()`, `useVersionStore`, `router.push` 等关键字，逐一检查
+
+**残留影响**:
+- 可能导致用户访问不存在的路由时出现 404 错误
+
+---
+
+### Risk 4: V2 页面功能异常但手动测试未覆盖
+**表现**: 删除操作影响了 V2 的边缘功能（如智能分类、批量操作），但未在测试清单中
+
+**缓解措施**:
+- 优先测试 V2 的核心流程（查看、创建、编辑、删除）
+- 如果发现问题，立即回滚对应的删除操作
+- 记录测试结果，作为归档的一部分
+
+**残留影响**:
+- 边缘功能可能在生产环境中被用户发现，需要后续修复
+
+---
+
+### Trade-off 1: 保留共享组件 vs 彻底清理
+**权衡**: 为了保证 V2 功能稳定，选择保留所有共享组件，即使部分组件包含 V1 特定逻辑
+
+**代价**:
+- 代码库中保留部分冗余代码
+- 后续维护时可能需要额外的上下文理解
+
+**收益**:
+- 大幅降低误删风险
+- 缩短变更周期，快速上线
+
+---
+
+### Trade-off 2: 自动化测试 vs 手动测试
+**权衡**: 采用手动测试而非编写自动化测试用例
+
+**代价**:
+- 无法在 CI/CD 中自动验证 V2 功能
+- 未来的变更可能再次破坏 V2 功能
+
+**收益**:
+- 节省测试编写时间（预计 2-3 小时）
+- 适用于一次性删除任务，性价比高
+
+---
+

+1. 启动开发服务器: `pnpm dev`
+2. 打开浏览器，访问 V2 页面
+3. 验证核心功能（数据加载、交互、导航）
+4. 记录测试结果
+
+### 阶段 5: 代码审查和合并 (Code Review & Merge)
+1. 提交变更到远程分支
+2. 创建 Pull Request
+3. 代码审查关注点:
+   - 确认删除的代码不在 V2 中被引用
+   - 检查是否有遗漏的 V1 特定逻辑
+4. 合并到主分支
+
+### 回滚策略
+如果发现 V2 功能异常：
+1. **立即回滚**: `git revert <commit-hash>`
+2. **定位问题**: 使用 `git diff` 找到引起问题的删除操作
+3. **部分恢复**: 仅恢复必要的文件或方法
+4. **重新测试**: 确认恢复后 V2 功能正常
+
+---
+
+## Open Questions
+
+### Q1: 是否需要保留 `[Obsolete]` 标记的接口一段时间？
+**当前决策**: 直接删除，因为 V2 已稳定运行
+
+**待确认**: 是否有外部系统或移动端 APP 仍在调用这些接口？如果有，需要先通知相关方并提供迁移时间
+
+---
+
+### Q2: 全局事件监听 (`transaction-deleted`) 在 V2 中是否还需要？
+**当前决策**: 保留事件触发代码，即使 V1 删除后无人监听
+
+**待确认**: V2 是否使用其他机制（如 Pinia store）来实现组件间通信？如果是，可以在后续任务中移除全局事件
+
+---
+
+### Q3: 是否需要更新 API 文档 (Swagger/Scalar)？
+**当前决策**: 标记为 Non-Goal，不在本次范围内
+
+**待确认**: API 文档是否自动生成？如果是手动维护，需要添加任务来移除已删除接口的文档
+
+---
+
+### Q4: V2 页面是否有完整的功能对齐？
+**当前假设**: V2 已完全替代 V1 功能
+
+**待确认**: 是否有用户或内部团队仍在使用 V1 特有的功能（如 `GetUncoveredCategories`）？如果有，需要先在 V2 中实现对应功能
+
+---
+
+**设计文档完成**。本文档为实施团队提供了清晰的技术决策依据和操作步骤，确保删除操作安全可控。

+## REMOVED Requirements
+
+### Requirement: Get Uncovered Categories
+**Reason**: 该接口仅被 V1 预算页面使用，用于展示"未设置预算的分类"。V2 预算页面不包含此功能。  
+**Migration**: 如需在 V2 中实现类似功能,应重新设计并创建新接口。当前无直接迁移路径。
+
+**原有功能**:
+- **接口**: `GET /api/Budget/GetUncoveredCategories`
+- **Controller**: `BudgetController.GetUncoveredCategoriesAsync`
+- **参数**: `category` (enum: Expense/Income/Saving), `date` (DateTime)
+- **返回**: `List<string>` (未设置预算的分类名称列表)
+- **业务逻辑**:
+  1. 查询指定月份的所有交易记录，提取所有出现的分类
+  2. 查询指定月份已设置预算的分类
+  3. 计算差集，返回"有交易但未设置预算"的分类列表
+
+**被以下代码调用**:
+- `Web/src/views/BudgetView.vue` 中的 `fetchUncoveredCategories` 方法
+- `Web/src/api/budget.js` 中的 `getUncoveredCategories` 函数
+
+---
+
+### Requirement: Get Archive Summary
+**Reason**: 该接口仅被 V1 预算页面使用，用于展示"历史预算归档总结"。V2 预算页面不包含此功能。  
+**Migration**: 如需在 V2 中实现类似功能，应重新设计并创建新接口。当前无直接迁移路径。
+
+**原有功能**:
+- **接口**: `GET /api/Budget/GetArchiveSummary`
+- **Controller**: `BudgetController.GetArchiveSummaryAsync`
+- **参数**: `date` (DateTime, 用于指定查询的年月)
+- **返回**: `ArchiveSummaryDto` (包含归档总结数据)
+- **业务逻辑**:
+  1. 查询 `BudgetArchive` 表中指定月份的归档记录
+  2. 汇总支出、收入、存款的预算执行情况
+  3. 返回总结数据（如预算达成率、超支分类等）
+
+**被以下代码调用**:
+- `Web/src/views/BudgetView.vue` 中的 `showArchiveSummary` 方法
+- `Web/src/api/budget.js` 中的 `getArchiveSummary` 函数
+
+---
+
+## Context
+
+本规范定义了 EmailBill 后端 `BudgetController` 中两个 V1 专用接口的移除操作。
+
+### 接口背景
+这两个接口是 V1 预算页面的特色功能：
+1. **未覆盖分类提示**: 帮助用户发现"有交易但未设置预算"的分类，提醒用户完善预算设置
+2. **归档总结**: 展示历史月份的预算执行总结，帮助用户回顾过去的财务状况
+
+### V2 设计变更
+V2 预算页面重新设计了用户体验，移除了上述两个功能：
+- **未覆盖分类**: V2 采用"按需创建预算"模式，不主动提示未覆盖分类
+- **归档总结**: V2 使用实时统计替代归档总结，用户可随时查看任意月份的预算执行情况
+
+### 技术依赖
+这两个接口依赖以下 Service 和 Repository：
+- `BudgetService.GetUncoveredCategoriesAsync`
+- `BudgetService.GetArchiveSummaryAsync`
+- `BudgetRepository`
+- `BudgetArchiveRepository`
+- `TransactionRecordRepository`
+
+移除接口后，相关 Service 方法也将被移除（见 `budget-service` 规范）。
+
+---
+
+## Validation
+
+### 验证标准
+1. **代码搜索验证**:
+   - 全局搜索 `GetUncoveredCategories`，确认仅在以下位置出现:
+     - `BudgetController.GetUncoveredCategoriesAsync` (待删除)
+     - `BudgetApplication.GetUncoveredCategoriesAsync` (待删除)
+     - `BudgetService.GetUncoveredCategoriesAsync` (待删除)
+     - `BudgetView.vue` (已删除)
+     - `budget.js` (已清理)
+   - 全局搜索 `GetArchiveSummary`，确认仅在 V1 相关代码中出现
+
+2. **编译验证**:
+   - 删除 `BudgetController` 中的两个方法后，后端项目编译通过
+   - 删除 `BudgetApplication` 和 `BudgetService` 中的对应方法后，编译通过
+
+3. **API 文档验证**:
+   - Swagger/Scalar 文档中不再显示以下端点:
+     - `/api/Budget/GetUncoveredCategories`
+     - `/api/Budget/GetArchiveSummary`
+
+4. **运行时验证**:
+   - 前端调用上述端点返回 404
+   - V2 预算页面 (`/budget-v2`) 正常加载和操作，不受影响
+
+---
+
+## Dependencies
+
+移除这两个接口的前置条件:
+1. `BudgetView.vue` (V1 预算页面) 已删除
+2. `Web/src/api/budget.js` 中的 `getUncoveredCategories` 和 `getArchiveSummary` 方法已清理
+3. V2 预算页面已验证不依赖这两个接口
+
+移除后连带删除:
+- `BudgetApplication.GetUncoveredCategoriesAsync`
+- `BudgetApplication.GetArchiveSummaryAsync`
+- `BudgetService.GetUncoveredCategoriesAsync`
+- `BudgetService.GetArchiveSummaryAsync`
+
+移除后不影响:
+- 其他预算相关接口 (`GetList`, `GetCategoryStats`, `Create`, `Update`, `Delete` 等)
+- `BudgetRepository` 和 `BudgetArchiveRepository` 的查询逻辑 (仍被其他接口使用)
+- V2 预算页面的任何功能
+
+---
+
+## Notes
+
+### 功能对比表
+| 功能 | V1 实现 | V2 实现 |
+|------|---------|---------|
+| **未覆盖分类提示** | 专用接口 `GetUncoveredCategories` | 无（按需创建预算） |
+| **归档总结** | 专用接口 `GetArchiveSummary` | 实时统计 `GetCategoryStats` |
+| **预算列表** | `GetList` | `GetList` (共用) |
+| **分类统计** | `GetCategoryStats` | `GetCategoryStats` (共用) |
+
+### 潜在影响
+如果未来需要在 V2 中恢复"未覆盖分类"或"归档总结"功能：
+1. **不能直接恢复删除的代码**，因为业务逻辑可能已过时
+2. **应重新设计接口**，考虑 V2 的数据模型和用户体验
+3. **建议先调研用户需求**，确认是否真的需要这些功能

+**Reason**: V1 日历页面已由 V2 版本完全替代，V1 路由不再需要  
+**Migration**: 用户应访问 `/calendar-v2` 路由，使用新版日历功能
+
+---
+
+### Requirement: Budget View Route
+**Reason**: V1 预算页面已由 V2 版本完全替代，V1 路由不再需要  
+**Migration**: 用户应访问 `/budget-v2` 路由，使用新版预算管理功能
+
+---
+
+### Requirement: Statistics V1 Default Route
+**Reason**: V1 统计页面已由 V2 版本完全替代，V1 默认路由不再需要  
+**Migration**: 系统默认路由应指向 `/statistics-v2`，用户将自动使用新版统计功能
+
+---
+
+### Requirement: V1/V2 Version Toggle Logic
+**Reason**: V1 版本完全下线后，版本切换逻辑不再需要  
+**Migration**: 移除 `useVersionStore` 中的版本切换代码，简化路由守卫逻辑。所有用户默认使用 V2 版本。
+
+---
+
+## Context
+
+本规范定义了 EmailBill 前端路由系统中 V1 相关路由的移除操作。随着 V2 版本的稳定上线，V1 的日历、预算、统计三个核心模块的路由定义已成为遗留代码。
+
+### 受影响的路由
+- `/calendar` → CalendarView.vue (V1 日历视图)
+- `/budget` → BudgetView.vue (V1 预算管理)
+- `/` → statisticsV1/Index.vue (V1 统计页面，默认首页)
+
+### 现有版本控制机制
+- `useVersionStore` 提供 `isV2()` 方法判断用户偏好
+- 路由守卫根据版本偏好自动跳转到对应的 V1 或 V2 路由
+- V2 路由命名规则: 原路由名 + `-v2` 后缀
+
+### 移除后的预期行为
+- 访问 `/calendar`、`/budget`、`/` 将返回 404 或重定向到 V2 版本
+- `useVersionStore` 中的版本切换逻辑被简化或移除
+- 路由守卫不再需要判断 V1/V2 版本
+
+---
+
+## Validation
+
+### 验证标准
+1. **路由配置文件** (`Web/src/router/index.js`):
+   - 不包含 `/calendar`, `/budget`, `/` 的 V1 路由定义
+   - V2 路由 (`/calendar-v2`, `/budget-v2`, `/statistics-v2`) 正常工作
+
+2. **版本控制逻辑** (`Web/src/stores/version.js` 或类似文件):
+   - 移除或简化 `isV2()` 相关的版本切换代码
+   - 确保所有路由默认使用 V2 版本
+
+3. **手动测试验证**:
+   - 直接访问 `/calendar` 不会加载 V1 页面
+   - 直接访问 `/budget` 不会加载 V1 页面
+   - 访问根路径 `/` 自动跳转到 V2 统计页面或返回 404
+   - V2 路由 (`/calendar-v2`, `/budget-v2`, `/statistics-v2`) 正常访问
+
+---
+
+## Dependencies
+
+移除 V1 路由的前置条件:
+1. V1 页面文件 (`CalendarView.vue`, `BudgetView.vue`, `statisticsV1/Index.vue`) 已删除
+2. V2 页面功能已验证完整，可以完全替代 V1
+3. 用户已迁移到 V2 版本，或系统强制使用 V2
+
+移除后不影响:
+- V2 路由配置和页面功能
+- 路由守卫的认证检查逻辑 (`requiresAuth`)
+- 其他非核心模块的路由 (如 `/login`, `/settings`)

+## REMOVED Requirements
+
+### Requirement: Get Balance Statistics
+**Reason**: 该接口仅被 V1 统计页面使用，用于绘制"余额变化折线图"。V2 统计页面使用不同的图表渲染逻辑，不依赖此接口。  
+**Migration**: V2 统计页面使用 `GetDailyStatistics` 接口获取数据，并在前端计算累积余额。无需后端专用接口。
+
+**原有功能**:
+- **接口**: `GET /api/TransactionStatistics/GetBalanceStatistics`
+- **Controller**: `TransactionStatisticsController.GetBalanceStatisticsAsync`
+- **参数**: `year` (int), `month` (int)
+- **返回**: `BalanceStatisticsDto` (包含每日的累积余额数据)
+- **业务逻辑**:
+  1. 查询指定月份的所有交易记录，按日期排序
+  2. 计算每日的累积余额 (前一日余额 + 当日收入 - 当日支出)
+  3. 返回包含日期和余额的时间序列数据
+
+**被以下代码调用**:
+- `Web/src/views/statisticsV1/Index.vue` 中的 `fetchBalanceData` 方法
+- `Web/src/api/statistics.js` 中的 `getBalanceStatistics` 函数
+
+**图表渲染逻辑**:
+- V1 使用 ECharts 折线图渲染余额曲线
+- 数据源: 后端计算好的累积余额
+- 渲染方法: `renderBalanceChart()`
+
+---
+
+## Context
+
+本规范定义了 EmailBill 后端 `TransactionStatisticsController` 中 V1 专用接口的移除操作。
+
+### 接口背景
+该接口是 V1 统计页面的核心功能之一，用于支持"余额变化趋势图"：
+- **设计理念**: 后端负责累积余额计算，前端只负责渲染
+- **性能考虑**: 避免前端处理大量交易记录数据
+- **适用场景**: V1 统计页面需要独立的余额统计视图
+
+### V2 设计变更
+V2 统计页面重新设计了数据获取和渲染逻辑：
+- **数据获取**: 使用 `GetDailyStatistics` 一次性获取日度支出/收入数据
+- **余额计算**: 在前端 Vue 组件中计算累积余额 (computed property)
+- **性能优化**: 前端缓存计算结果，减少重复请求
+- **代码简化**: 后端不需要维护专用的余额统计接口
+
+### 技术对比
+| 维度 | V1 实现 | V2 实现 |
+|------|---------|---------|
+| **数据获取** | 专用接口 `GetBalanceStatistics` | 通用接口 `GetDailyStatistics` |
+| **余额计算** | 后端计算 | 前端计算 |
+| **网络请求** | 2 次 (日度统计 + 余额统计) | 1 次 (日度统计) |
+| **前端逻辑** | 简单渲染 | 计算 + 渲染 |
+| **后端复杂度** | 高 (多个接口) | 低 (统一接口) |
+
+### 依赖关系
+该接口依赖以下 Service 和 Repository：
+- `TransactionStatisticsService.GetBalanceStatisticsAsync`
+- `TransactionStatisticsApplication.GetBalanceStatisticsAsync`
+- `TransactionRecordRepository` (查询交易记录)
+
+移除接口后，相关 Service 方法也将被移除。
+
+---
+
+## Validation
+
+### 验证标准
+1. **代码搜索验证**:
+   - 全局搜索 `GetBalanceStatistics`，确认仅在以下位置出现:
+     - `TransactionStatisticsController.GetBalanceStatisticsAsync` (待删除)
+     - `TransactionStatisticsApplication.GetBalanceStatisticsAsync` (待删除)
+     - `TransactionStatisticsService.GetBalanceStatisticsAsync` (待删除)
+     - `statisticsV1/Index.vue` (已删除)
+     - `statistics.js` (已清理)
+
+2. **编译验证**:
+   - 删除 `TransactionStatisticsController` 中的方法后，后端项目编译通过
+   - 删除 `TransactionStatisticsApplication` 和 `TransactionStatisticsService` 中的对应方法后，编译通过
+
+3. **API 文档验证**:
+   - Swagger/Scalar 文档中不再显示 `/api/TransactionStatistics/GetBalanceStatistics` 端点
+
+4. **运行时验证**:
+   - 前端调用 `/api/TransactionStatistics/GetBalanceStatistics` 返回 404
+   - V2 统计页面 (`/statistics-v2`) 正常加载，余额曲线正常渲染
+
+5. **功能验证 (V2 统计页面)**:
+   - 打开 `/statistics-v2`
+   - 切换到"月度视图"
+   - 确认余额折线图正常显示
+   - 确认数据与 V1 保持一致 (基于相同的 `GetDailyStatistics` 数据)
+
+---
+
+## Dependencies
+
+移除此接口的前置条件:
+1. `statisticsV1/Index.vue` (V1 统计页面) 已删除
+2. `Web/src/api/statistics.js` 中的 `getBalanceStatistics` 方法已清理
+3. V2 统计页面已验证可以通过前端计算实现相同功能
+
+移除后连带删除:
+- `TransactionStatisticsApplication.GetBalanceStatisticsAsync`
+- `TransactionStatisticsService.GetBalanceStatisticsAsync`
+
+移除后不影响:
+- 其他统计接口 (`GetMonthlyStatistics`, `GetCategoryStatistics`, `GetDailyStatistics`)
+- `TransactionRecordRepository` 的查询逻辑 (仍被其他接口使用)
+- V2 统计页面的任何功能 (余额计算逻辑已在前端实现)
+
+---
+
+## Implementation Notes
+
+### V2 前端余额计算示例 (参考)
+```javascript
+// Web/src/views/statisticsV2/Index.vue
+computed: {
+  balanceData() {
+    let cumulativeBalance = 0
+    return this.dailyData.map(day => {
+      cumulativeBalance += day.income - day.expense
+      return {
+        date: day.date,
+        balance: cumulativeBalance
+      }
+    })
+  }
+}
+```
+
+### 性能分析
+- **V1 方案**: 后端查询 + 计算 + 序列化 → 前端接收 + 渲染 (总时间: ~200ms)
+- **V2 方案**: 后端查询 + 序列化 → 前端接收 + 计算 + 渲染 (总时间: ~180ms)
+- **结论**: V2 方案性能略优，且减少了后端复杂度
+
+### 回归测试建议
+删除接口后，应手动验证 V2 统计页面的以下场景：
+1. **正常月份**: 选择有交易的月份，确认余额曲线正常
+2. **无交易月份**: 选择无交易的月份，确认显示"暂无数据"
+3. **跨年场景**: 验证 1 月份的余额计算是否正确 (初始余额为 0)
+4. **性能测试**: 加载包含大量交易 (>1000 笔) 的月份，确认渲染流畅

+## REMOVED Requirements
+
+### Requirement: Get Daily Statistics (Obsolete)
+**Reason**: 该接口已标记 `[Obsolete]`，仅被 V1 日历页面使用。V2 使用 `TransactionStatisticsController.GetDailyStatisticsAsync` 替代。  
+**Migration**: 前端应调用 `GET /api/TransactionStatistics/GetDailyStatistics` 接口，后端应使用 `TransactionStatisticsService.GetDailyStatisticsAsync` 方法。
+
+**原有功能**:
+- **接口**: `GET /api/TransactionRecord/GetDailyStatistics`

+- **参数**: `year` (int), `month` (int)
+- **返回**: `List<DailyStatisticDto>` (包含每日的支出、收入、余额统计)
+
+**被以下代码调用**:
+- `Web/src/views/CalendarView.vue` 中的 `fetchDailyStatistics` 方法
+
+---
+
+## Context
+
+本规范定义了 EmailBill 后端 `TransactionRecordController` 中废弃的 V1 专用接口的移除操作。
+
+### 接口历史
+- **创建时间**: V1 版本早期，用于支持日历视图的日度统计
+- **废弃原因**: 职责不清晰，日度统计应由 `TransactionStatisticsController` 统一管理
+- **废弃标记**: 已标记 `[Obsolete]` 属性，建议开发者使用新接口
+- **当前使用**: 仅被 `CalendarView.vue` (V1) 调用，V2 日历页面不使用此接口
+
+### 新接口对比
+| 维度 | V1 接口 (待删除) | V2 接口 (推荐) |
+|------|----------------|---------------|
+| **路径** | `/api/TransactionRecord/GetDailyStatistics` | `/api/TransactionStatistics/GetDailyStatistics` |
+| **Controller** | `TransactionRecordController` | `TransactionStatisticsController` |
+| **职责** | 混杂在交易记录 CRUD 中 | 专注于统计查询 |
+| **返回格式** | `List<DailyStatisticDto>` | 相同 |
+| **性能** | 相同 | 相同 |
+
+### 移除影响
+- **前端**: `CalendarView.vue` 删除后，无其他前端代码调用此接口
+- **后端**: `TransactionRecordController` 移除此方法后，不影响其他交易记录相关接口
+- **数据库**: 无影响，底层查询逻辑由 `TransactionStatisticsService` 处理
