/// The sections that describe *code* are skipped; the one that describes

/// The original spec returned early here, which answered "is my model set up?"

/// be asking - a docs-only tree, or one whose languages drep does not
/// register. The two halves are asserted together because dropping either
/// makes the other trivially satisfiable.
