//! Module: response::exact_key
//! Responsibility: planner-free exact-key projection handoff.
//! Does not own: typed adapter decoding, admission limits, or store access.
//! Boundary: keeps one decoded projection per distinct input key plus the
//! original-position mapping required by public typed reads.

use crate::value::OutputValue;

/// Internal projection from one bounded exact-key batch.
