A deterministic AGGREGATE over ONE corpus's COMPLETE set — the calculated-query shape ("how many X", "break X down by Y", "which is most common"). Requires domain; optional filter scopes the set (e.g. {"spirit":"gin"}); optional by (a record field) returns the count PER value, sorted, with the largest. Built ON enumerate, so it inherits the completeness contract: over an INCOMPLETE set it ABSTAINS rather than undercount. It counts on GROUND and refuses to crown a "best"/worth ranking (that has no oracle — the user's call). For the records/categories themselves use enumerate.
