 | **guardrails/**          | Hosts the NASK‑PIB guardrail service (`nask_pib_guard_app.py`). It receives a JSON payload, chunks the text, runs a Hugging‑Face classification pipeline, and returns a safety verdict (`safe` flag + detailed per‑chunk results). |
-| **maskers/**             | Contains the **BANonymizer** (`banonymizer.py`) – a lightweight Flask service that performs token‑classification based anonymisation of input text.                                                                                |
