## 🚨 Critical Notes & Warnings
|
|
|
|
### Architecture Preservation

|
- **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
