No declared repository license as of 2026-10-28. Current author-reported Sonnet 5.5 results use 22 prompts: MetricFlow 21/22 across three runs, Malloy 21/22 across three runs, raw SQL 12/22 in one run. Repository warns the sample is small (about ±18 percentage points with 22 prompts) and the published runs isolate only interface effects, not the full model/interface/harness matrix.
