# Aicher (MVP) – Visual Causal Tutor

Tri-panel MVP for causal tutoring on conditional probability.  
Left: input & reasoning. Center: reasoning graph. Right: diagnosis + minimal fix.

## Run locally
```bash
pip install -r requirements.txt
python app.py
```

### Notes

- Works offline via rules. Optional tiny model: `TinyLlama/TinyLlama-1.1B-Chat-v1.0` (CPU).
- Extend `compute_reasoning` and `make_graph_image` for other domains (code AST checks, physics constraints).
