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 2: Audit Log Core Features (Phase 2)

Sprint: Sprint 2 Priority: P0 (Must Have) Estimated: 3-4 days (Day 27-30) Owner: Backend Team

Description

Enhance audit logging with core features including changed fields detection (old vs new values JSON diff), user context tracking, multi-tenant isolation, query API, and integration tests.

Acceptance Criteria

  • Changed fields tracking implemented with JSON diff
  • User context (UserId) automatically captured
  • Multi-tenant isolation for audit logs enforced
  • Query API implemented for retrieving audit history
  • Integration tests with >= 90% coverage
  • Performance target met (< 5ms overhead)
  • All tests passing

Technical Requirements

Enhanced Features:

  • Changed Fields Detection: Compare old vs new values, store only changed fields
  • User Context: Automatically capture current user from HTTP context
  • Multi-Tenant Isolation: Filter audit logs by TenantId
  • Query API: REST endpoints for audit history retrieval

Technology Stack:

  • System.Text.Json for JSON diffing
  • PostgreSQL JSONB for flexible storage
  • CQRS pattern for query handlers

Tasks

  • 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

Progress: 0/5 tasks completed

Dependencies

Prerequisites:

  • Story 1 completed (Audit Log Foundation)
  • EF Core Interceptor implemented
  • AuditLog entity and repository ready

Definition of Done

  • All 5 tasks completed
  • Changed fields detection working correctly
  • User context captured from HTTP context
  • Multi-tenant isolation verified
  • Query API endpoints working
  • All tests passing (>= 90% coverage)
  • Performance benchmark met (< 5ms overhead)
  • Code reviewed and approved
  • Git commit created

Notes

Performance Target: < 5ms overhead per SaveChanges operation JSON Diff: Store only changed fields, not full entity snapshots (storage optimization)
