## 🚀 Key Features Implemented

### Data Transformers

Each transformer includes:

- Full HuggingFace dataset integration
- Warbler document structure generation
- MIT license compliance
- FractalStat realm/activity level metadata
- Dataset-specific optimizations

### Notable Features

| Feature | Details |
|---------|---------|
| **arXiv Limit** | `--arxiv-limit` prevents 2.55M paper overload |
| **Novel Chunking** | Auto-splits long texts (~1000 words/chunk) |
| **Error Handling** | Try-catch with graceful failure messages |
| **CLI Integration** | Seamless command-line interface |
| **Metadata** | All docs include license, realm, activity level |
| **Backward Compat** | Legacy datasets still supported |

### Testing Strategy

- **Unit Tests**: Each transformer independently
- **Integration Tests**: Pack creation and document format
- **Performance Tests**: Large dataset handling
- **Mocking**: HuggingFace API calls mocked for reliability

## 🔍 What to Test Next

### Immediate Testing

```bash
# 1. Verify CLI works
python -m warbler_cda.utils.hf_warbler_ingest list-available

# 2. Test single dataset ingestion
python -m warbler_cda.utils.hf_warbler_ingest ingest -d prompt-report

# 3. Run full test suite
pytest tests/test_new_mit_datasets.py -v

# 4. Test integration with retrieval API
python -c "from warbler_cda.retrieval_api import RetrievalAPI; api = RetrievalAPI(); print('✓ Integration OK')"
```

### Integration Testing

1. Load created packs with `pack_loader.py`
2. Add documents to `RetrievalAPI`
3. Verify FractalStat coordinate generation
4. Test hybrid retrieval scoring

### Performance Testing

1. Large arXiv ingestion (10k papers)
2. Novel chunking performance
3. Memory usage under load
4. Concurrent ingestion

## 📞 Support & Troubleshooting

### Common Issues

**Issue**: HuggingFace API rate limiting

- **Solution**: Use `--arxiv-limit` to control ingestion size

**Issue**: Memory exhaustion with large datasets

- **Solution**: Use smaller `--arxiv-limit` or ingest in batches

**Issue**: Missing dependencies

- **Solution**: `pip install datasets transformers`

**Issue**: Tests fail with mock errors

- **Solution**: Ensure unittest.mock is available (included in Python 3.3+)
