//! The inventory both tiers state, and the records a tier writes over it.
//!
//! Units, definitions, and references come from the snapshot alone, so both
//! tiers state the same ones in the same order. Only the records — the
//! candidates and gaps of each reference — depend on which tier is answering,
//! which is why the two entry points share everything above this line.
