 5. **Test with real data** instead of mock data in production code
 
 ### Code Review Checklist
-- [ ] Training functions actually perform training
+- [x] Training functions actually perform training
-- [ ] Model interfaces are properly implemented
+- [x] Model interfaces are properly implemented
-- [ ] No placeholder return values in critical functions
+- [x] No placeholder return values in critical functions
 - [ ] Mock data only used in tests, not production
 - [ ] All TODO/FIXME items are tracked and prioritized
+
+## ✅ **FIXED STATUS UPDATE**
+
+**All critical placeholder functions have been fixed with real implementations:**
+
+### **Fixed Functions**
+
+1. **CNN Training Functions** - ✅ FIXED
+   - `web/clean_dashboard.py`: `_perform_real_cnn_training()` - Now includes proper optimizer, backward pass, and loss calculation
+   - `core/training_integration.py`: `_train_cnn_on_trade_outcome()` - Now performs actual CNN training with trade outcomes
+
+2. **COB RL Training Functions** - ✅ FIXED  
+   - `web/clean_dashboard.py`: `_perform_real_cob_rl_training()` - Now includes actual RL agent training with experience replay
+   - `core/training_integration.py`: `_train_cob_rl_on_trade_outcome()` - Now performs real COB RL training with market data
+
+3. **Decision Fusion Training** - ✅ ALREADY IMPLEMENTED
+   - `web/clean_dashboard.py`: `_perform_real_decision_training()` - Already had real implementation
+
+### **Key Improvements Made**
+
+- **Added proper optimizers** to all models (Adam with 0.001 learning rate)
+- **Implemented backward passes** with gradient calculations
+- **Added experience replay** for RL agents
+- **Enhanced checkpoint saving** with real model state
+- **Integrated cumulative imbalance** features into training
+- **Added proper loss weighting** based on trade outcomes
+- **Implemented real state/action/reward** structures for RL training
+
+### **Result**
+Models are now actually learning from trading actions rather than just creating placeholder checkpoints. This resolves the core issue that was preventing proper model training and causing debugging difficulties.
