|------|--------|-------------|------------|
| **File splitting breaks tests** | High | Medium | Incremental changes, full test suite after each split |
| **API changes break consumers** | Medium | Low | Preserve public API through re-exports |

### Medium Risk
| Risk | Impact | Probability | Mitigation |
|------|--------|-------------|------------|
| **Test pass rate drops** | Medium | Low | Run tests after each split, fix immediately |
| **Build time increases** | Low | Low | Parallel compilation, optimized feature flags |

### Low Risk
| Risk | Impact | Probability | Mitigation |
|------|--------|-------------|------------|
| **Documentation drift** | Low | Medium | Update docs with code changes |
