## Three Paths Forward

Choose your path based on your needs:

### Path A: Quick Framework Validation (5 minutes)
**Goal**: Verify everything works with mock model
**Commands**:
```bash
cd "c:/Build Folder/email-sorter"
source venv/Scripts/activate

# Run quick validation
pytest tests/ -v --tb=short
python -m src.cli test-config
python -m src.cli run --source mock --output test_results/
```
**Result**: Confirms framework works correctly

### Path B: Real Model Integration (30-60 minutes)
**Goal**: Replace mock model with real LightGBM model
**Two Sub-Options**:

#### B1: Train Your Own Model on Enron Dataset
```bash
# Parse Enron emails (already downloaded)
python -c "
from src.calibration.enron_parser import EnronParser
from src.classification.feature_extractor import FeatureExtractor
from src.calibration.trainer import ModelTrainer

parser = EnronParser('enron_mail_20150507')
emails = parser.parse_emails(limit=5000)

extractor = FeatureExtractor()
trainer = ModelTrainer(extractor, ['junk', 'transactional', 'auth', 'newsletters',
                                     'social', 'automated', 'conversational', 'work',
                                     'personal', 'finance', 'travel', 'unknown'])

# Train (takes 5-10 minutes on this laptop)
results = trainer.train([(e, 'unknown') for e in emails])
trainer.save_model('src/models/pretrained/classifier.pkl')
"

# Verify
python tools/setup_real_model.py --check
```

#### B2: Download Pre-trained Model
```bash
# If you have a pre-trained model URL
python tools/download_pretrained_model.py \
  --url https://example.com/lightgbm_model.pkl \
  --hash abc123def456

# Or if you have local file
python tools/setup_real_model.py --model-path /path/to/model.pkl

# Verify
python tools/setup_real_model.py --check
```

**Result**: Real model installed, framework uses it automatically

### Path C: Full Production Deployment (2-3 hours)
**Goal**: Process all 80k+ emails with Gmail integration
**Prerequisites**: Path B (real model) + Gmail OAuth
**Steps**:

1. **Setup Gmail OAuth**
   ```bash
   # Get credentials from Google Cloud Console
   # https://console.cloud.google.com/
   # - Create OAuth 2.0 credentials
   # - Download as JSON
   # - Place as credentials.json in project root

   # Test Gmail connection
   python -m src.cli test-gmail
   ```

2. **Test with 100 Emails**
   ```bash
   python -m src.cli run \
     --source gmail \
     --limit 100 \
     --output test_results/
   ```

3. **Process Full Dataset**
   ```bash
   python -m src.cli run \
     --source gmail \
     --output marion_results/
   ```

4. **Review Results**
   - Check `marion_results/results.json`
   - Check `marion_results/report.txt`
   - Review accuracy metrics
   - Adjust thresholds if needed

## Testing Your Setup

### Framework Validation
```bash
# Test configuration loading
python -m src.cli test-config

# Test Ollama (if running locally)
python -m src.cli test-ollama

# Run full test suite
pytest tests/ -v
```

### Mock Pipeline (No Real Data Needed)
```bash
python -m src.cli run --source mock --output test_results/
```

### Real Model Verification
```bash
python tools/setup_real_model.py --check
```

### Gmail Connection Test
```bash
python -m src.cli test-gmail
```

---

## Performance Expectations

### With Mock Model (Testing)
- Feature extraction: ~50-100ms per email
- ML prediction: ~10-20ms per email
- Total time for 100 emails: ~30-40 seconds

### With Real Model (Production)
- Feature extraction: ~50-100ms per email
- ML prediction: ~5-10ms per email (LightGBM is faster)
- LLM review (5% of emails): ~2-5 seconds per email
- Total time for 80k emails: 15-25 minutes

### Calibration Phase
- Sampling: 1-2 minutes
- LLM category discovery: 2-3 minutes
- Model training: 5-10 minutes
- Total: 10-15 minutes

---

## Troubleshooting

### Problem: "Model not found" but framework running
**Solution**: This is normal - system uses mock model automatically
```bash
python tools/setup_real_model.py --check  # Shows current status
```

### Problem: Ollama tests failing
**Solution**: Ollama is optional, LLM review will skip gracefully
```bash
# Not critical - framework has graceful fallback
python -m src.cli run --source mock
```

### Problem: Gmail connection fails
**Solution**: Gmail is optional, test with mock first
```bash
python -m src.cli run --source mock --output results/
```

### Problem: Low accuracy with mock model
**Expected behavior**: Mock model is for framework testing only
```python
# Check model info
from src.classification.ml_classifier import MLClassifier
c = MLClassifier()
print(c.get_info())  # Shows is_mock: True
```

## What NOT to Do

❌ **Do NOT**:
- Try to use mock model in production (it's not accurate)
- Process all emails before testing with 100
- Skip Gmail credential setup (use mock for testing instead)
- Modify core classifier code (framework is complete)
- Skip the test suite validation
- Use Ollama if laptop is low on resources (graceful fallback available)

✅ **DO**:
- Test with mock first
- Integrate real model before processing
- Start with 100 emails then scale
- Review results and adjust thresholds
- Keep this file for reference
- Use the tools provided for model integration
