Researchers have developed HERALD, a new offline audit system designed to evaluate and improve the reward mechanisms for search agents. HERALD uses counterfactual interventions to distinguish between candidate-visible and oracle information, aiming to ensure that high scores accurately reflect retrieved evidence and to prevent manipulation. Initial tests on Qwen3_8B models across several question-answering benchmarks showed that while HERALD can detect some attacks, a citation-laundering attack remains successful, indicating a need for further hardening of the reward system.
