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.
