In SAS Model Manager, the champion/challenger framework is configured for a credit scoring model. The challenger receives 20% of scoring requests. After 30 days, the challenger's Gini (0.71) exceeds the champion's Gini (0.66) with statistical significance. What action does the champion/challenger framework enable?

Short Explanation
Here's the deal — the framework gives you the comparative performance evidence you need, but it doesn't promote the challenger by itself. You still need the governance review and approval workflow to make the challenger the champion.
Full Explanation
The correct action is that the champion/challenger framework provides comparative performance evidence to support a governance-controlled decision to promote the challenger after review and approval. SAS Model Manager uses it for controlled side-by-side evaluation of a challenger against the production champion. The 20% traffic, 30-day window, and statistically significant Gini difference supply evidence, but promotion requires human review and approval through the SAS Model Manager workflow; it is not automatic. The option saying automatic replacement when Gini difference exceeds 0.05 is wrong because promotion is not automatic. The option saying the challenger is discarded after evaluation and must be re-registered is wrong because it can be promoted. The option saying both models continue indefinitely regardless of performance is wrong because the framework is meant to lead to a promotion decision, not perpetual parallel operation.
