## 🔧 Technical Achievements

### Infrastructure Improvements
1. **Fixed AgentRepository API** - Aligned with Agent model
2. **Fixed EventRepository** - Manual ID generation for SQLite compatibility
3. **Fixed BulkOperationService** - Updated event logging to match EventRepository API
4. **Fixed ItemRepository** - DateTime handling for deleted_at field
5. **Added pydantic-settings** - Required dependency for config management

### New Services Implemented
1. **TraceabilityService** - Complete traceability matrix and impact analysis
2. **BulkOperationService** - Enhanced with preview and validation

### Test Infrastructure
- ✅ Async fixtures working perfectly
