Cited by assistant and question type

Citation counts per assistant and question type. Counts only: a share would need a denominator that lives in the metrics store.

Counts of answers, one per answer per domain. Persona columns are never summed into a single figure, and a citation count is not a rate: the denominator lives in the metrics store.
