//! Module: db::query::plan::tests::group_having
//! Covers grouped HAVING comparison semantics that are part of the planner's
//! grouped contract surface.
//! Does not own: generic predicate semantics beyond the grouped HAVING
//! compatibility lane.
//! Boundary: keeps grouped HAVING regression coverage in the plan owner
//! `tests/` boundary instead of under one leaf helper file.
