## 🚧 Potential Blockers

### Technical Challenges
1. **Textual Learning Curve**
   - Risk: Medium
   - Mitigation: Study official examples, use Rich documentation

2. **Async Data Loading**
   - Risk: Medium
   - Mitigation: Use Textual's worker pattern, add loading states

3. **Terminal Compatibility**
   - Risk: Low
   - Mitigation: Test on major terminals, use fallback rendering

### Resource Constraints
1. **Time**: 7 days is tight for comprehensive TUI
   - Mitigation: Focus on core features, defer polish to Week 3

2. **Testing**: UI testing can be tricky
   - Mitigation: Use pytest-textual, add visual regression tests
