## Aggregate Metrics

| Method | Avg Precision | Avg Recall | Avg F1 | Exact Match Rate |
|---|---:|---:|---:|---:|
| naive | 0.5161 | 0.6567 | 0.4254 | 0.1167 |
| instructed | 1.0000 | 0.3849 | 0.4627 | 0.2333 |

## Notes

- `naive`: single partition `[n]`.
- `instructed`: heuristic partition `[n-1, 1]` for `n > 1`.
- `verified_structural`: non-oracle structural scorer (balance + step penalty + chunking heuristics).
- `verified_structural_ensemble`: non-oracle vote across top structural partitions.
- `verified_consensus`: non-oracle self-consistency scorer (retrieval stability + structure + match density).

No theorem discharge is claimed by this benchmark.
