abstract: 'LeanRoute-216: 216 kernel-verified Lean proofs for 36 fixed propositions (36 human-reviewed originals plus 180 generated variants), organized as parent-to-candidate edges with benchmark, machine and human route labels, and 955 LLM-judge route judgments from six models (930 held-out, 25 development). Provided as the original workbook and as two CSV exports (proofs and model judgments).'
