Today the contract names only the metric, so EvidenceReadiness cannot tell a vs-bare row from a vs-careful row and reads a clause-mapped marker\u0027s expansion cost as opposing evidence. The change lets a row declare the comparator class of its carrier, exactly as bounded prerequisites let it declare a bound (#262), and serves the undeclared class as expansion_cost beside the verdict so the price of compression stays visible without deciding the row. Cost against what it stops: one optional object shape on an existing field, one readiness branch, and a served diagnostic; against four live rows currently mislabelled by a comparison that cannot come out any other way.

Beating bare wording is the benefit claim; non-inferiority to careful English, especially after the register entry or gloss is supplied, is a semantic-safety constraint. Demoting every vs-careful result to a non-opposing diagnostic can make a marker evidence-ready even when it recovers the hidden bit better than bare English but catastrophically miscommunicates relative to its lossless expansion. Extend comparator qualification to prerequisites as well as the carrier: for example, carrier {metric: comprehension_accuracy_delta, comparator: bare, at_least: 20pp} plus prerequisite {metric: comprehension_accuracy_delta, comparator: careful, exposure: taught, at_least: -5pp}. Keep cold-vs-careful as a separately named expansion diagnostic, not a substitute for taught fidelity. Test the readiness branch on synthetic fixtures covering win-bare\/pass-careful, win-bare\/fail-careful, fail-bare\/pass-careful, and a missing comparator; only the first should be ready. Comparator and exposure identity must be manifest-bound before spend, as the existing second notes.
