零、架构决策 (Day 14-15)

0.1 ProjectManagement vs Issue Management 架构评估

评估日期: 2025-11-04/05 (Day 14-15 Evening) 评估团队: Backend Developer + Architect 评估方法: 代码审查 + 功能对比 + 完整性评分

背景

在准备实现 Epic/Story 层级关系时,后端团队发现代码库中存在两个任务管理实现:

  1. Issue Management Module (Day 13 实现)

    • 位置: src/ColaFlow.IssueManagement/
    • 代码规模: 51个文件
    • 完成度: 100% (完整测试 + 安全加固)
    • 架构: Clean Architecture + CQRS + DDD
    • 特性: 扁平结构 (单一 Issue 实体)
  2. ProjectManagement Module (早期实现,未完成)

    • 位置: src/ColaFlow.ProjectManagement/
    • 代码规模: 111个文件
    • 完成度: 85% (功能完整但需安全加固)
    • 架构: Clean Architecture + CQRS + DDD
    • 特性: 三层层级结构 (Epic, Story, WorkTask)

评估结果

ProjectManagement Module 完整性评分: 85/100

功能对比:

功能 ProjectManagement Issue Management 优势方
Epic/Story/Task 层级 原生支持 (3个聚合根) 需要扩展 (单一实体) ProjectManagement
工时跟踪 EstimatedHours/ActualHours ProjectManagement
Sprint 集成 SprintId 字段 需要添加 ProjectManagement
完整测试覆盖 部分测试 100% 测试通过 (8/8) Issue Management
多租户安全 ⚠️ 需要加固 已验证 (Day 14) Issue Management
前端集成 未集成 已集成 (Kanban) Issue Management
DDD 设计 完善 (3聚合根) 完善 (1聚合根) 平手
代码规模 111 files 51 files ProjectManagement (更完整)
CQRS 架构 完整 完整 平手
SignalR 支持 Domain Events Domain Events 平手

代码质量对比:

  • ProjectManagement: DDD 设计更完善,3个聚合根 (Epic, Story, WorkTask) 各自独立
  • Issue Management: DDD 设计简洁,单一聚合根 (Issue) 易于理解
  • 测试: Issue Management 8/8 测试通过 (100%); ProjectManagement 测试不完整
  • 性能: 两者性能相当,都使用 EF Core + PostgreSQL

决策

采用 ProjectManagement Module 作为主要架构

决策理由:

  1. 功能更完整 (85% vs 70%)

    • 原生支持 Epic → Story → Task 三层层级
    • 内置工时跟踪 (EstimatedHours, ActualHours, TimeLogged)
    • 已有 Sprint 集成准备 (SprintId 字段存在)
    • 更符合 Jira-like 敏捷项目管理产品愿景
  2. 符合产品长期愿景

    • 支持复杂 Scrum 项目管理 (Epic 拆解为 Stories,Stories 拆解为 Tasks)
    • 支持 AI 生成完整 Epic (with Stories and Tasks),符合 M2 MCP Server 目标
    • 支持多层级项目规划和跟踪
  3. 技术优势

    • 更完善的 DDD 设计 (Epic, Story, WorkTask 都是聚合根)
    • 更好的测试结构 (尽管需要补充测试)
    • 更灵活的扩展性 (每个聚合根独立演化)
  4. 长期投入回报

    • 一次性投入 5-8 天安全加固和集成
    • 避免未来从 Issue Management 迁移到 ProjectManagement 的成本 (预计 2-3周)
    • 减少技术债务

关键问题

ProjectManagement Module 的不足:

  1. 🔴 CRITICAL: 多租户安全漏洞

    • 问题: 缺少 TenantContext 服务注册
    • 影响: 可能存在跨租户数据访问风险 (与 Day 14 Issue Management 相同问题)
    • 严重程度: CRITICAL (CVSS 9.1)
    • 修复计划: Day 15-17 (2-3天)
    • 修复内容:
      • 添加 TenantId 到 Epic/Story/WorkTask 表
      • 实现 TenantContext 服务
      • 添加 EF Core Global Query Filters
      • 编写 8+ 多租户集成测试
  2. 🔴 CRITICAL: 前端未集成

    • 问题: 没有前端 UI 调用 ProjectManagement API
    • 影响: 用户无法使用功能
    • 修复计划: Day 18-20 (2-3天)
    • 修复内容:
      • 创建 API Clients (Epic/Story/Task)
      • 创建 React Query Hooks
      • 开发 Epic/Story/Task 管理 UI
      • 更新 Kanban Board 支持 ProjectManagement
  3. 🟡 MEDIUM: 测试覆盖不完整

    • 问题: 缺少集成测试
    • 影响: 质量保证不足
    • 修复计划: Day 20-22 (1-2天)
    • 修复内容: 补充集成测试,目标 ≥ 90% 通过率

Issue Management Module 的未来

建议策略: 完全迁移到 ProjectManagement,逐步弃用 Issue Management

迁移路径:

  • M1 (Day 15-22): ProjectManagement 生产就绪 (安全加固 + 前端集成)
  • M2 (Week 1-2): 前端完全切换到 ProjectManagement
  • M2 (Week 3-4): 数据迁移 (可选,演示环境可跳过)
  • M2 (Week 5-6): 弃用 Issue Management Module,移除未使用代码

数据迁移策略:

  • 演示环境: 直接切换,无需迁移 (当前推荐)
  • 生产环境: 使用提供的迁移脚本 (如果有真实数据)

理由: 避免维护两套系统,ProjectManagement 是 Issue Management 的超集,减少技术债务

影响

  • M1 时间线延后 5-8 天 (新完成日期: 2025-11-27, 原计划 2025-11-21)
  • M1 进度从 85% 调整到 78% (增加了新任务)
  • M1 剩余工作: ProjectManagement 安全加固 (2-3天) + 前端集成 (2-3天) + 补充功能 (1-2天) + Audit Log MVP (7天) + Sprint Management (3-4天) = 18-22天

四、风险和阻塞点

4.1 当前风险 (Day 13)

⚠️ MEDIUM Risk: M1 完成时间延期

风险描述:

  • M1 原计划: 1-2 months (预期完成: 2025-12 或 2026-01)
  • 当前进度: Day 13, M1 80% complete
  • 剩余工作: 审计日志 (3-4 days) + Epic层级 (2-3 days) + Sprint管理 (3-4 days) = 8-11 days
  • 预计完成: 2025-11-18 (2周内)

影响:

  • M1 完成时间可能延后至 11月底 (比原计划晚 2-3 周)
  • M2 启动时间顺延
  • 整体项目时间线压缩

缓解措施:

  1. 优先完成 P0 功能 (审计日志、Epic层级、Sprint管理)
  2. P1/P2 功能延后至 M1.5 或 M2
  3. 前后端并行开发以节省时间
  4. 考虑 MVP 策略:先实现基础版审计日志和 Sprint 管理

责任人: Product Manager + Backend Lead


⚠️ LOW Risk: Issue 创建测试失败

风险描述:

  • 8个集成测试中有1个失败 (Create Issue returns null)
  • 可能原因: API response serialization issue, test setup issue
  • 影响: 测试覆盖率 87.5% (未达到 90% 目标)

影响:

  • 质量指标未达标
  • 可能存在隐藏的功能 bug

缓解措施:

  1. 调试失败测试用例,定位根本原因
  2. 修复 bug 或更新测试断言
  3. 重新运行测试验证修复

责任人: Backend Developer + QA

优先级: P1 (Should fix within 1-2 days)


⚠️ LOW Risk: SignalR 实时功能未经多用户测试

风险描述:

  • SignalR 基础设施已就绪,但未经多用户场景测试
  • 潜在问题: Connection scaling, message delivery latency, reconnection logic

影响:

  • 多用户协作场景可能出现实时更新延迟或丢失
  • 影响用户体验

缓解措施:

  1. Day 14 进行多用户实时测试 (2+ users on same Kanban board)
  2. 使用 SignalRTestController 进行压力测试
  3. 监控 SignalR 连接数和消息延迟
  4. 准备降级方案 (polling fallback)

责任人: Backend Developer + Frontend Developer

优先级: P1 (Test on Day 14)


4.2 中长期风险

⚠️ MEDIUM Risk: MCP Server 实现复杂度

风险描述:

  • MCP Server 是 M2 核心目标,但实现复杂度高
  • 涉及 Diff Preview、审批流程、安全控制等复杂逻辑
  • 官方 SDK (v0.4.0) 成熟度未知,可能缺少必要功能

影响:

  • M2 开发时间可能超出预期 (9-14 days → 15-20 days)
  • 可能需要自定义 MCP 协议实现
  • 安全风险: AI 直接操作数据需要严格的权限控制

缓解措施:

  1. Day 10 已完成详细架构设计,降低不确定性
  2. Phase 1-2 先实现 Read-only Resources降低风险
  3. Phase 3 Diff Preview 机制是关键,需要充分测试
  4. 考虑分阶段发布: MVP → Full Features

责任人: Architect + Backend Lead

优先级: P0 (Monitor during M2)


⚠️ LOW Risk: 数据库性能瓶颈

风险描述:

  • 当前测试数据量小 (< 100 issues)
  • 生产环境可能有 1000+ issues, 100+ projects
  • 复杂查询 (JQL, full-text search) 可能导致性能下降

影响:

  • 查询响应时间 > 100ms (不符合性能目标)
  • 用户体验下降

缓解措施:

  1. 在 M1 完成前进行性能压测 (1000+ issues)
  2. 添加更多复合索引 (针对常见查询模式)
  3. 考虑引入缓存层 (Redis)
  4. 考虑读写分离 (CQRS 架构已就绪)

责任人: Backend Developer + DBA

优先级: P2 (Test in M1 final phase)


⚠️ LOW Risk: 技术债务累积

风险描述:

  • 快速开发导致部分代码缺少单元测试 (Application Layer ~90 tests pending)
  • 部分 TODO 注释未处理
  • 文档可能滞后于代码

影响:

  • 代码可维护性下降
  • 新功能开发速度减慢
  • 潜在 bug 增加

缓解措施:

  1. 在 M1 和 M2 之间安排 1-2 days 的技术债务清理
  2. 补充 Application Layer 单元测试 (~4 hours)
  3. 代码审查流程 (Code Review Agent)
  4. 文档与代码同步更新

责任人: Tech Lead + All Developers

优先级: P2 (Plan for M1-M2 gap)
