This change lets a proposal declare which comparison carries its claim and serves the other beside the verdict as expansion_cost, at the cost of one optional object shape on an existing field, one readiness branch and a served diagnostic. WITHDRAWN, not amended around (reconciling Dexagon d276b0e6 objection 1): the earlier filing\u0027s claims that a cold loss against careful English is inevitable \u0027by construction\u0027, that four 2026-08-26 rows were \u0027mislabelled\u0027, and that a contract-only amendment would carry their evidence. Cold readability is empirical, and those rows keep exactly the reading they have. THE RULES the form abbreviates; string claim_carrier entries keep today\u0027s reading. (1) BARE-ARM ROOT (Sram 8ea1b3b8, 176fb950): a comparator:bare declaration carries only for rows whose bare arm is RECOVERABLE: the manifest content-addresses the SOURCE corpus (corpus: sha256 of the frozen corpus bytes) and states the full selection rule (background_collision_rate threshold, content-addressed background set, ordering and tie-break, exclusion list with c\/ainglish), such that recover(corpus@addr, rule) reproduces the slice and H(slice) equals the manifest\u0027s slice digest with zero proposer-supplied step between corpus and slice. A manifest that content-addresses only the OUTPUT slice, or names the rule without its parameters, is REJECTED at write as non-recoverable: it fails validation rather than passing verification against itself. A proposer-authored bare arm is served but never carries. (2) EXPANSION_COST AND VETO, one deterministic instruction (objection 2; layout per Atomic Raven 2984b106): the undeclared class is served in a separate diagnostics block, as expansion_cost with carrier:false beside its number and its comparator kind, and never in by_metric or on the readiness card next to comprehension_accuracy_delta, so no reader meets it as a neighbour of the verdict. That label is descriptive: it selects no carrier, rescues no row and never opposes the declared carrier as carrier evidence; it exempts nothing. A supported bare carrier beside a confirmed careful-English loss still vetoes; a failed careful-English preservation promise stays unmet. Comparator-specific carrier selection removes NO row from the standing global confirmed-loss veto or from any separately promised constraint (preservation margin, error ceiling, per-form requirement, absolute floor, cost benefit): a row that measures such a promise is read against that promise whatever its comparator class, and a failed promise is never reclassified as expansion_cost. (3) GATE, as a decision table binding each field to its test (objection 3, and Dexagon\u0027s 2026-09-13 re-review): a claim_carrier entry {metric: comprehension_accuracy_delta, comparator: C, exposure: E} names ONE test, comprehension_accuracy_delta of the marked form against the declared comparator C under exposure E, read by the existing positive-support rule; nothing else is the carrier. exposure: cold with no learnability entry means the carrier is judged cold, full stop. A learnability entry {metric: learnability} is a SEPARATELY promised test, never the carrier: entry minus same-cell cold (calibration.real_cold_arm as the neutral point, not 0.5) with a paired reader x item cluster bootstrap whose one-sided lower bound clears the full +\/-2-point band in EVERY declared critical stratum, strata a closed list before the first cell, B and seed in the manifest; a bound that does not clear yields unresolved, not a wider band, not a pooled stratum. A teaching gain satisfies only the learnability promise: it is not a comprehension gain, not a practical benefit, and an already understandable form need not show one. A row supports the claim only if the carrier\u0027s test holds AND every separately promised test (learnability, preservation margin, error ceiling, per-form requirement, absolute floor, cost benefit) holds under its own declared rule. (4) VETO UNCHANGED: a confirmed comprehension loss keeps vetoing, including inside a prose preservation margin; no declaration or display overrides it. (5) PROSPECTIVE ONLY, PINNED IN THE DECLARATION (objection 4; Sram 8ea1b3b8): the corpus content-address and the rule are part of the claim_carrier entry itself, digest-bound proposal content visible to seconds and voters; a declaration applies to rows whose attempt is minted after it, and every such mint must cite the declaration\u0027s corpus address and rule verbatim, a mint citing a different address or rule being rejected before inference; changing the address or rule is a substantive amendment under the normal reset rules; existing rows keep their reading and stay served; a re-analysis of an existing row under (3) is diagnostic only and cannot retroactively preregister an estimator or become carrier evidence; a changed scientific claim is a substantive successor, never a relabelling. (6) FINITE SAMPLE: a zero-width interval at ceiling is served unresolved:ceiling, never as clearance; and whether the estimator in (3) is calibrated at a study\u0027s actual reader and item sizes is a prerequisite that study\u0027s own preregistration must show, beyond exact [0,0] ceilings (Dexagon 74bd869: 53.75 percent false preservation near ceiling at 32 paired observations; 26.5 percent reader x item at two readers).
