🚨 Critical Notes & Warnings
Architecture Preservation
- CRITICAL: Maintain Modified Feature Capsule architecture
- CRITICAL: All changes must preserve AI-maintainability
- 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
