# Examples

## `load_and_score.py`

End-to-end demo. Loads the v8a adapter on top of a frozen `Qwen/Qwen2.5-7B` and prints all four semiotic readouts for an input passage.

```bash
cd examples
pip install -r ../requirements.txt
python load_and_score.py --text "Vaccine mandates are an obvious public health win."
```

First run downloads `Qwen/Qwen2.5-7B` (~15 GB) from HuggingFace.
