Evidence and limits
Finding: Optimizing a model as part of a model-plus-decision-maker system can improve system accuracy or fairness relative to isolated rejection rules.
Impact: Watch system-aware deferral as an evaluation concept. Reject synthetic gains as authority to automate routing.
Boundary: The experiments largely simulate decision makers. Next: can prospective human evidence reproduce benefits under changing expertise and costs?
Flags: synthetic experts; fairness objective choices
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
