Implemented architecture review recommendations for verdict taxonomy and verification metadata
Modified verification data models to implement architecture review recommendations. Expanded AuditVerdict enum to distinguish between different types of disagreement: AGREE_WITH_ROUNDING handles rounding tolerance cases, SOURCE_DRIFT captures temporal cutoff differences between DB snapshot and external API queries, and DEFINITION_MISMATCH flags cohort/metric definition misalignment. Added denominator, cohort_size, and snapshot_date fields to VerificationResult to support the review’s emphasis on denominator contracts and temporal awareness. This enables the system to distinguish “Ivonescimab 20 vs 27 trials” scenarios where disagreement stems from snapshot date drift rather than factual error. Comment explicitly attributes changes to GPT-5.5 review feedback about including denominator and cohort size in verification results.
Concepts: [“what-changed”,“why-it-exists”,“problem-solution”]
Facts: [“AuditVerdict enum expanded from 4 to 7 values: added AGREE_WITH_ROUNDING, SOURCE_DRIFT, DEFINITION_MISMATCH”,“VerificationResult dataclass gained three optional fields: denominator, cohort_size, snapshot_date”,“New verdict types enable distinction between factual disagreement vs temporal drift vs metric definition mismatch”,“to_dict() serialization conditionally includes new metadata fields only when present”,“Changes directly implement GPT-5.5 architecture review guidance about snapshot-aware verdicts”]
