## Usage
```python
from huggingface_hub import hf_hub_download
import joblib, pandas as pd
model = joblib.load(hf_hub_download(
    repo_id='indianakhil/engine-predictive-maintenance-model',
    filename='best_model.pkl'))
pred = model.predict(X)  # 0=Normal, 1=Faulty
prob = model.predict_proba(X)[:, 1]  # Fault probability
```
