### Risk Assessment

#### 🔴 High Risk Tasks
1. **API-001/002**: Critical path - affects all video playback
2. **FORMAT-001**: Core logic change with widespread impact
3. **LAUNCH-001**: Platform compatibility complexity

#### 🟡 Medium Risk Tasks
1. **UI-001**: Complex component with multiple states
2. **TEST-001**: Comprehensive testing required
3. **SETTINGS-001**: UI integration complexity

#### 🟢 Low Risk Tasks
1. **CLEANUP tasks**: Non-critical path items
2. **Documentation**: Can be done post-deployment
3. **UI-002**: Simple visual updates
