Story 1: Audit Log Foundation (Phase 1)
Sprint: Sprint 2 Priority: P0 (Must Have) Estimated: 3-4 days (Day 23-26) Owner: Backend Team
Description
Implement the foundation for audit logging system to support compliance and debugging requirements. This phase focuses on building the core infrastructure including database schema, EF Core interceptor, and basic tracking for Create/Update/Delete operations.
Acceptance Criteria
- AuditLog database table created with proper schema and indexes
- EF Core SaveChangesInterceptor implemented for automatic audit logging
- Basic CREATE/UPDATE/DELETE operations are automatically tracked
- Unit tests with >= 90% coverage
- Performance benchmark: < 5ms overhead per save operation
- All tests passing
Technical Requirements
Database Schema:
- Table:
AuditLogs - Columns:
Id,TenantId,EntityType,EntityId,Action,UserId,Timestamp,OldValues,NewValues - Indexes: Composite index on
(TenantId, EntityType, EntityId),Timestamp,UserId - Storage: PostgreSQL JSONB for
OldValues/NewValues
Technology Stack:
- EF Core 9.0 SaveChangesInterceptor API
- PostgreSQL JSONB
- MediatR (optional for domain events)
Tasks
- 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
Progress: 0/5 tasks completed
Dependencies
Prerequisites:
- ✅ ProjectManagement Module 95% Production Ready (Day 16)
- ✅ Multi-Tenant Security Complete (Day 15)
- ✅ EF Core 9.0 infrastructure
Definition of Done
- All 5 tasks completed
- 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 Scope: Phase 1 focuses on foundation only - Changed Fields tracking will be in Story 2 (Phase 2)
