## Summary

A new paper on arXiv explores how to structure authority for AI reviewers in multi-agent systems. The authors examine whether reviewers should have broad override power or only intervene when they can prove a violation and propose a compliant fix. Their tests on two open-weight models—Qwen and Mistral—showed that an evidence gate reduced incorrect overrides of correct proposals by 96% across 96 spatial-policy tasks while still catching most violations. However, the effectiveness varied: Qwen’s reviewer declined welfare-only repairs that Mistral frequently attempted, and Mistral still overrode all correct proposals. The study concludes that interface design influences reviewer behavior but isn’t a universal safeguard, and that competence, action rules, and binding jurisdiction shape both corrections and risks.

## Key points

- An evidence gate reduced incorrect overrides by 96% in tests on Qwen and Mistral across 96 tasks
- Mistral’s reviewer still overrode all correct proposals despite the gate, while Qwen declined welfare-only repairs
- Interface design affects reviewer behavior but isn’t a model-independent solution for oversight

## Why it matters

This work could guide how AI systems delegate authority to reviewers, balancing correction of errors with risks of overreach in real-world applications.
