The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments show that RADAR consistently outperforms strong single- and multi-agent baselines across datasets and backbones, improving omission detection accuracy while reducing reasoning cost.

C2weakest assumption

That complementary role assignment and adversarial debate over shared retrieved evidence, combined with dual-threshold early termination, reliably uncovers omitted context without introducing new biases or requiring perfect retrieval.

C3one line summary

RADAR is a role-anchored multi-agent debate framework that improves half-truth detection by reasoning about omitted context in noisy retrieved evidence.
