## Phase 4: Advanced Features (Weeks 7-8)

### 4.1 Visualization
- [ ] Implement ASCII graph rendering
- [ ] Add Neo4j export option
- [ ] Create RTM matrix export
- [ ] Build visualization queries

### 4.2 Smart Contracts

- [ ] Implement audit trail tracking
- [ ] Add verification hooks

### 4.3 Performance & Optimization
- [ ] Add query caching
- [ ] Implement batch operations
- [ ] Optimize graph algorithms
- [ ] Add performance monitoring

## Phase 5: Polish & Documentation (Weeks 9-10)

### 5.1 Testing
