2. ✅ Clean and preprocess data (7 methods)
3. ✅ Engineer 50+ features automatically
4. ✅ Train 4 ML algorithms with AutoML
5. ✅ Create ensembles and calibrated models
6. ✅ Score in real-time or batch
7. ✅ Generate reason codes and interpretations

### Example Usage (Ready Now):
```python
from riskx import RiskDataConnector, RiskCleaner, RiskFeatureEngine
from riskx import RiskAutoModel, ScoringEngine

# Load data
connector = RiskDataConnector()
data = connector.from_csv("applications.csv")

# Clean data
cleaner = RiskCleaner()
data_clean = cleaner.auto_clean(data, target_column="default")

# Engineer features
feature_engine = RiskFeatureEngine()
data_features = feature_engine.auto_features(data_clean, target="default")

# Train models
model = RiskAutoModel()
X = data_features.drop("default", axis=1)
y = data_features["default"]
results = model.train_auto(X, y, algorithms=['logistic', 'rf', 'xgboost'])

# Score new applications
scorer = ScoringEngine(model.get_best_model())
new_app = {"income": 50000, "credit_history": 5, "debt_ratio": 0.3}
result = scorer.score_single(new_app)
print(f"Score: {result['score']}, Rating: {result['rating']}")
```
