//! Module: query::plan::validate::grouped
//! Responsibility: grouped-plan semantic validation slices (policy, cursor, structure, projection).
//! Does not own: executor runtime fail-closed checks or grouped execution orchestration.
//! Boundary: planner validation composes these helpers before route/executor handoff.
