## Summary
- **Best FA**: -0.234
- **Oracle calls**: 2,611
- **Method**: Beam search with frozen surrogate, no DDPP fine-tuning

## Algorithm
Beam search guided by a surrogate model (not FA oracle directly).
Surrogate is frozen — no online learning/fine-tuning.
Ablation showing that fine-tuning the model is necessary.
