Validate promising model screens through native continuations

A promising isolated model response is a screening result, not evidence that the native application will make the same decision. Repeat the full caller history through actual tool execution, context updates and follow-up requests before changing a production model or API. Verify transmitted tool permissions as well as arguments and resulting state: faithful transport can still produce an unsupported business assertion. Compare clear-answer controls alongside the ambiguous target, preserve every attempt, and report incomplete provider-status evidence separately. Small repeated samples can reject a proposed upgrade without establishing a universal model ranking.
