50 canonical-lookup queries each paired with a right-answer URI regex. For each query, cupertino search "<query>" --limit 10 was invoked via the develop-tip binary with cupertino.config.json set to baseDirectory: ~/.cupertino-dev. Top-10 URIs were extracted from stdout in document order. Per-query MRR, P@1, P@5, NDCG@10 computed against the regex. No statistical test reported (single-system mode); the harness's paired Wilcoxon path is exercised only in comparison mode.
