## [CURRENT FOCUS]

- [ ] Confirm stability in Hugging Face Space.
- [ ] Improve RAG fallback hit rate by enriching museum loaders.

## [TECHNICAL DEBT]

- Loader scripts currently have limited error handling for network timeouts.
- Background archival task in `app.py` uses basic `threading.Thread`; consider a more robust queue if traffic increases.
