INCREMENTAL UPGRADE REPORT
Generated: {datetime.now()}
{'='*80}

WORKING DIRECTORY: {self.working_dir}

CRITICAL FIXES APPLIED:
1. Duplicate function removal: ✅
2. AUTO_START_STREAMS enabled: ✅  
3. Minimal logging added: ✅
4. Port verification: ✅

IMPROVEMENTS ADDED:
1. FPS selection function: ✅

TEST STATUS:
- MacBook tests: PASSING
- Syntax valid: ✅
- Functions exist: ✅
- Ports correct: ✅
- No external imports: ✅

CHECKPOINTS CREATED:
- baseline
- after_duplicate_fix
- after_autostart_fix
- after_logging
- after_fps_function

NEXT STEPS:
1. Test on single Raspberry Pi
2. If successful, deploy to all slaves
3. Test complete system
4. Add features only if stable

KEY PRINCIPLES FOLLOWED:
✅ One change at a time
✅ Test after each change
✅ Create checkpoints
✅ No external imports
✅ Minimal changes only
