- **CRITICAL**: Docker-first development must continue
- **CRITICAL**: No local package installations outside containers

### Risk Mitigation
- Every phase has rollback procedures
- Feature flags for gradual deployment
- Parallel implementations during transitions
- Comprehensive testing at each phase
