## Data Structure: Warbler Document Format

All transformers produce documents matching this structure:

```python
{
    "content_id": "source-type/unique-identifier",
    
    "content": """Formatted text with:
    - Dataset-specific fields
    - Structured information
    - Human-readable format
    """,
    
    "metadata": {
        # Standard fields
        "pack": "warbler-pack-<dataset>",
        "source_dataset": "huggingface/dataset-path",
        "license": "MIT",
        
        # Warbler FractalStat fields
        "realm_type": "category",           # scholarly|methodological|narrative|procedural|business|educational
        "realm_label": "subcategory",       # arxiv|prompt_engineering|generated_fiction|etc
        "lifecycle_stage": "emergence",     # Always emergence for new ingestions
        "activity_level": 0.5-0.8,         # 0.5=low, 0.8=high
        "dialogue_type": "content_type",   # scholarly_discussion|technical_discussion|etc
        
        # Dataset-specific fields
        # (see each transformer for specific metadata)
    }
}
```

## Integration Points with Warbler-CDA

### 1. Pack Creation

```python
ingestor = HFWarblerIngestor()
docs = ingestor.transform_arxiv(limit=1000)
pack_path = ingestor.create_warbler_pack(docs, "warbler-pack-arxiv")
```

### 2. Pack Loading

```python
from warbler_cda.pack_loader import WarblerPackLoader
packs = WarblerPackLoader.load_pack_directory("/path/to/packs")
```

### 3. Document Enrichment

```python
from warbler_cda.retrieval_api import RetrievalAPI
api = RetrievalAPI()
for doc in docs:
    api.add_document(doc["content_id"], doc["content"])
    # Automatically:
    # - Computes embeddings
    # - Generates FractalStat coordinates
    # - Stores in context_store
```

### 4. Hybrid Retrieval

```python
query = RetrievalQuery(
    semantic_query="machine learning optimization",
    fractalstat_hybrid=True,
    weight_semantic=0.6,
    weight_fractalstat=0.4
)
assembly = api.retrieve_context(query)
```

---

## Error Handling

All transformers include:

- `.get()` with defaults for missing fields
- `isinstance()` checks for flexible dataset formats
- CLI try-catch blocks with user-friendly error messages
- Graceful handling when dataset load fails
- Conditional pack creation (only if docs generated)

---

## Performance Considerations

### Memory Management

- **arXiv**: Use `--arxiv-limit` to control ingestion
  - Example: 100 papers ~50MB, 10k papers ~5GB
  - Recommended limit: 10k-50k papers
  
- **Novels**: Automatic chunking prevents single document explosion
  - 100k word novel → ~100 chunks
  - Each chunk ~100 tokens (embedding-friendly)

### Processing Speed

- Small datasets (50-300 docs): <10 seconds
- Medium datasets (1k-10k): 30-120 seconds
- Large datasets (100k+): Use with `--limit` parameters

---

## CLI Examples

```bash
# Ingest single dataset
python -m warbler_cda.utils.hf_warbler_ingest ingest -d arxiv

# Limit arXiv to 5000 papers
python -m warbler_cda.utils.hf_warbler_ingest ingest -d arxiv --arxiv-limit 5000

# Ingest multiple datasets
python -m warbler_cda.utils.hf_warbler_ingest ingest \
  -d arxiv --arxiv-limit 10000 \
  -d prompt-report \
  -d novels \
  -d manuals

# Ingest all MIT datasets
python -m warbler_cda.utils.hf_warbler_ingest ingest -d all --arxiv-limit 50000

# Change pack prefix
python -m warbler_cda.utils.hf_warbler_ingest ingest \
  -d novels \
  -p custom-prefix

# List available datasets
python -m warbler_cda.utils.hf_warbler_ingest list-available
```

## Deployment Notes

### Pre-Production

1. Run full test suite
2. Test with sample data (limit=10)
3. Verify pack creation
4. Test pack loading

### Production

1. Create packs with appropriate limits
