| """SentinelLLM — interactive safety & alignment demo (Hugging Face Space). | |
| Three live tabs: | |
| 1. Jailbreak Guard — paste a prompt, see the risk score, verdict, decoded | |
| obfuscation layers and which rules fired. | |
| 2. Bias Probe — enter a {GROUP} template, see per-axis counterfactual | |
| disparity. Optionally back it with a real HF toxicity | |
| classifier (unitary/toxic-bert) if HF_TOKEN is set. | |
| 3. Format Guard — paste messy model output, watch it get extracted, | |
| repaired and validated against a JSON Schema. | |
| The whole thing runs on the deterministic core in ``sentinel/`` — no key needed. | |
