Problem

For each model (mdl_name), determine the framework used most frequently across its versions. If two frameworks are tied in version count, pick the one with the higher average accuracy. Rank the resulting model-framework pairs by average accuracy from highest to lowest, and return only those in the top 3 ranks. If multiple pairs share the same rank, include all of them.

Summary

Every framework has a star model.
