Share of cases whose first recommended product is a human-verified target, in percent, after evidence-grounded verification; higher is better.
Metric: Identifier match at 1 (%; share of cases in which the first recommended product is one of the human-verified target product identifiers; multimodal multi-turn shopping requests from real assistant logs, answered by a tool-using agent over a frozen offline catalog with text and region-aware image retrieval (at most eight tool steps), followed by evidence-grounded verification and selection of the candidate pool by the policy model).
