Yaojia Wang ebb56cc9f8 feat(backend): Create Sprint 2 backend Stories and Tasks
Created detailed implementation plans for Sprint 2 backend work:

Story 1: Audit Log Foundation (Phase 1)
- Task 1: Design AuditLog database schema and create migration
- Task 2: Create AuditLog entity and Repository
- Task 3: Implement EF Core SaveChangesInterceptor
- Task 4: Write unit tests for audit logging
- Task 5: Integrate with ProjectManagement Module

Story 2: Audit Log Core Features (Phase 2)
- Task 1: Implement Changed Fields Detection (JSON Diff)
- Task 2: Integrate User Context Tracking
- Task 3: Add Multi-Tenant Isolation
- Task 4: Implement Audit Query API
- Task 5: Write Integration Tests

Story 3: Sprint Management Module
- Task 1: Create Sprint Aggregate Root and Domain Events
- Task 2: Implement Sprint Repository and EF Core Configuration
- Task 3: Create CQRS Commands and Queries
- Task 4: Implement Burndown Chart Calculation
- Task 5: Add SignalR Real-Time Notifications
- Task 6: Write Integration Tests

Total: 3 Stories, 16 Tasks, 24 Story Points (8+8+8)
Estimated Duration: 10-12 days

All tasks include:
- Detailed technical implementation guidance
- Code examples and file paths
- Testing requirements (>= 90% coverage)
- Performance benchmarks (< 5ms audit overhead)
- Multi-tenant security validation

Story 3: Sprint Management Module

Sprint: Sprint 2 Priority: P1 (Should Have) Estimated: 3-4 days (Day 31-34) Owner: Backend Team

Description

Implement complete Sprint management functionality to support agile sprint planning, tracking, and burndown analytics. Enable teams to organize work into time-boxed iterations.

Acceptance Criteria

  • Sprint entity created with proper domain logic
  • 9 CQRS API endpoints implemented (Create, Update, Delete, Get, List, Start, Complete, AddTask, RemoveTask)
  • Burndown chart data calculation implemented
  • SignalR real-time notifications for Sprint events
  • Multi-tenant isolation enforced
  • Integration tests with >= 90% coverage
  • All tests passing

Technical Requirements

Sprint Entity:

  • Fields: SprintId, TenantId, ProjectId, Name, Goal, StartDate, EndDate, Status (Planned/Active/Completed)
  • Relationships: Project (many-to-one), Tasks (one-to-many)
  • Business Logic: Validate dates, status transitions, capacity tracking

API Endpoints:

  1. POST /api/sprints - Create Sprint
  2. PUT /api/sprints/{id} - Update Sprint
  3. DELETE /api/sprints/{id} - Delete Sprint
  4. GET /api/sprints/{id} - Get Sprint by ID
  5. GET /api/sprints - List Sprints (with filters)
  6. POST /api/sprints/{id}/start - Start Sprint
  7. POST /api/sprints/{id}/complete - Complete Sprint
  8. POST /api/sprints/{id}/tasks/{taskId} - Add Task to Sprint
  9. DELETE /api/sprints/{id}/tasks/{taskId} - Remove Task from Sprint

Burndown Chart:

  • Calculate remaining story points per day
  • Track completed vs remaining work
  • Return data for chart visualization

Technology Stack:

  • Domain Layer: Sprint aggregate root + domain events
  • Application Layer: CQRS (5 commands + 4 queries)
  • Infrastructure Layer: PostgreSQL + EF Core
  • Real-time: SignalR SprintHub

Tasks

  • Task 1 - Create Sprint Aggregate Root and Domain Events
  • Task 2 - Implement Sprint Repository and EF Core Configuration
  • Task 3 - Create CQRS Commands and Queries
  • Task 4 - Implement Burndown Chart Calculation
  • Task 5 - Add SignalR Real-Time Notifications
  • Task 6 - Write Integration Tests

Progress: 0/6 tasks completed

Dependencies

Prerequisites:

  • ProjectManagement Module 95% Production Ready (Day 16)
  • SignalR Backend 100% Complete (Day 17)
  • Multi-Tenant Security Complete (Day 15)

Definition of Done

  • All 6 tasks completed
  • 9 API endpoints working
  • Burndown chart data calculation implemented
  • SignalR notifications working
  • All tests passing (>= 90% coverage)
  • Multi-tenant isolation verified
  • Code reviewed and approved
  • Git commit created

Notes

Sprint Lifecycle:

  1. Planned → Active (Start Sprint)
  2. Active → Completed (Complete Sprint)
  3. Cannot delete Active sprint (must complete first)

Burndown Chart Formula:

  • Total Story Points = Sum of all tasks in sprint
  • Remaining Story Points = Sum of incomplete tasks
  • Daily Burndown = [(Start Date, Total), ..., (Today, Remaining), ..., (End Date, 0 ideal)]
