## NEXT STEPS - WHEN YOU GET HOME

### Step 1: Model Training
```python
from src.calibration.enron_parser import EnronParser
from src.calibration.trainer import ModelTrainer

# Parse Enron
parser = EnronParser("enron_mail_20150507")
enron_emails = parser.parse_emails(limit=5000)

# Train real model
trainer = ModelTrainer(feature_extractor, categories, config)
results = trainer.train(labeled_emails)
trainer.save_model("models/lightgbm_real.pkl")
```

### Step 2: Gmail OAuth Setup

# Download credentials.json from Google Cloud Console
# Place in project root or config/
# Run: email-sorter --source gmail --credentials credentials.json
```

### Step 3: Full Pipeline Test
