## Presentation Arc

**Problem-to-Solution** (methods paper):
1. Background: Helmholtz scattering + FEM
2. Gap: Traditional AMR needs per-step FEM solve
3. Approach: Correction learning (teacher - physics)
4. Pipeline: 5-step workflow
5. Architecture: CorrectionGNN
6. Training: AUC=0.950, top-k 46.6%
7. Evaluation: Offline + Rollout
8. Visualization: AMR + step comparison
9. Validation: 5-check data quality
10. Innovation + Limitations + Summary

## Known Limitations

- No speaker notes (can be added manually)
- Some text-heavy slides (features, architecture) use structured layouts rather than figures
- Rollout improvement is modest (~2%) — presented honestly
- No rendered slide previews (no headless renderer available)
