Unverified50% confidenceDecision RuleExact time
CarbonLayer's position is: a number that looks precise but lacks sufficient supporting evidence should not be returned; a receipt can return a structure in which each metric's status is 'unavailable' and its value is null; zero is a value, unavailable is an evidence status, and the two should never be interchanged.

UnverifiedCarbonLayer prefers not to invent confidence scores, but instead uses evidence type and provenance to indirectly express the degree of trustworthiness, avoiding a false sense of precision.72% similarUnverifiedZero retention does not equal zero learning—the fact that data is not stored does not mean that patterns and information extracted from it will not influence the model in some form57% similarUnverifiedNULLIF returns NULL when its two arguments are equal, and is commonly used in conjunction with division to prevent divide-by-zero errors.55% similarUnverifiedFor environment-type failures, after fixing the environment, the corresponding test must actually be rerun; restoring connectivity does not equal having proven the code correct, and missing permissions cannot be bypassed by repeated requests.55% similarUnverifiedEach gold-standard contradiction is detectable on the basis of its evidence alone (recall 1.000), indicating no information gap at the data level and pointing to the retrieval stage rather than reasoning ability as the source of the problem.54% similar
