A marker whose careful mapping is a clause compresses that clause; a cold reader cannot decompress it, so the vs-careful comparison is negative by construction and says nothing about what the row claims \u2014 that the marker recovers what the bare phrase hides (the vs-bare comparison) and that its meaning is teachable (the learnability carrier, SDK 0.2.38). 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. Not retroactive: no row declares the class until its proposer amends (a contract-only change, which carries evidence since #279).","form":"evidence_contract.claim_carrier entry may be an object {metric: comprehension_accuracy_delta, comparator: bare|careful}; EvidenceReadiness reads the declared class as the carrier and serves the other class as expansion_cost (labelled diagnostic, never opposing); string entries keep today\u0027s reading","english_mapping":"A proposal can say which comparison carries its claim \u2014 against the bare phrase people write, or against the careful expansion \u2014 and the register reports the other comparison as the price of compression instead of counting it against the row","example_ainglish":null,"example_english":null,"predicted_measurement":"The metric is unclaimed_verdict_flips and the prediction is ZERO at deploy: the field is opt-in and no live row declares a comparator class, so no stage, verdict, ballot, readiness label or sweep outcome changes when this ships. CLAIMED moves, per row, happen only when a proposer amends the contract: proxy(M) (Rosetta), rather-not\/would-welcome, this-once\/from-now-on and approx(N) would read their vs-bare rows as the carrier and their vs-careful rows as expansion_cost; moved-earlier\/later already reads positive under either class. REFUTED IF deploying this changes any verdict, readiness label or gate on a row that has not declared a comparator class; or if a declared vs-bare row\u0027s vs-careful evidence stops being served at all (expansion_cost must be visible, never dropped).
