C.29:4.5b - Repair decision table

Failed or missing itemRequired repair
no CandidateMathObjectIf the problem still needs a mathematical lens for the next lens-use action, first name the ProblemStructureCue and write a MathLensUse.LensCandidateNote with the cheapest candidate lens family and next lens-use action; downgrade to ordinary prose or remove the mathematical claim only when no candidate lens changes action.
no LensMappingModeChoose a lens mapping mode or downgrade to analogy-only prompt.
no PreservedStructureRemove the claim-bearing mathematical phrase.
no LostStructure accountDescribe the omitted source distinctions. If none are lost for this use, explain why the relevant distinctions and operations are preserved. C.29.1 supplies the comparison.
no invariant, obstruction, distinction, or payoffKeep the phrase as didactic recognition cue or orientation-only.
no LensBoundedPredictionOrDistinction where decision, prediction, or model selection is being claimedBlock decision or assurance use; downgrade to analogy-only if no declared lens-use consequence is named.
evidence is analogy-onlyBlock decision, publication-as-established-model, assurance, release, and causal use unless evidence relation, validation regime, causal-use relation, or assurance result is supplied by its subject pattern.
no LensUseBoundaryValueBlock decision, publication, assurance, benchmark, and release use.
causal, intervention, policy, or counterfactual overreadApply C.28 or block causal use.
cross-context meaning, export, or substitution overreadApply F.9 when the export or substitution needs semantic correspondence between local senses; otherwise use the direct subject pattern. Block unsupported export or substitution.
scale, universality, knee, exponent, or scale-advantage claimApply C.18.1 for scale-law adequacy, C.19.1 for general method scale preference, or C.31.ASAP for architecture scale preference when that claim is made; otherwise keep the lens local and bounded by stop condition.
assurance or release useApply the direct release pattern, A.10 for evidence reliance, B.3 only for an actual named assurance claim, or relevant G patterns for their claims; block unsupported assurance or release use.
StopCondition is genericName the condition for narrowing or stopping, a no-lens exit, or source-return trigger. Include a blocked overread only when it passes F.19’s plausible-reader test.
