//! Module: db::session::sql::projection
//! Responsibility: session-owned SQL projection labels and payload shaping
//! helpers used by SQL statement result construction.
//! Does not own: shared projection validation or scalar execution mechanics.
//! Boundary: keeps outward SQL projection naming, payload types, and
//! SQL-specific row shaping together.
