 ## New Unified System
 
 ### Primary Class: `ModelManager` (`NN/training/model_manager.py`)
 
 #### Key Features:
-- ✅ **Unified Directory Structure**: Uses `@checkpoints/` structure
-- ✅ **All Model Types**: CNN, DQN, RL, Transformer, Hybrid
-- ✅ **Enhanced Metrics**: Comprehensive performance tracking
-- ✅ **Robust Saving**: Multiple fallback strategies
-- ✅ **Checkpoint Management**: W&B integration support
-- ✅ **Legacy Compatibility**: Maintains all existing APIs
