Constituent timestamps remain unchanged; comparisonCutoffAt is not a substitute baseline.","relativeValueObservation":"Stored highestSpreadAsset and lowestSpreadAsset describe IV-minus-realised spread ordering, not fair value. Legacy richestAsset and cheapestAsset aliases are omitted; missing neutral fields are not inferred.
