Context

Fraud outcomes are needed by payment operations, fulfillment, and support tooling. Each consumer needs different thresholds and response behavior.

Decision

FraudDetectionService publishes RiskScoreCalculated and FraudDetected events. Consumers decide whether to pause fulfillment, request manual review, or continue.

Consequences

Fraud rules can evolve independently from checkout. Consumers must document the thresholds they apply to each risk score band.
