Feature contributions

Human-readable explanation

The model produced risk category HIGH, trust score 47.5, and confidence score 1.0. The principal model factors increasing modeled risk were: Device relationship not established, New payment corridor. The principal model factors reducing modeled risk were: Established customer relationship, Established counterparty relationship, Complete metadata. This explanation describes model evidence only and does not constitute an institutional transaction decision.

8. Interpretation and limitations

• Controlled synthetic demonstrator assessment.
• Recommendation is advisory only.
• Final transaction authority remains with the participating institution.
