It can always hallucinate said report results/evidence/proof just the same. This approach tends to help reduce the hallucination rate though.

You can extend this further by using an adversarial agent trying to find mistakes in the other instance's logs in a loop where a 3rd neutral agent weighs the claims of the other two. This is also just another step in reducing error, it does not guarantee elimination of such errors. The latter is an impossible guarantee, even for humans.

Ask it to build you a simple and deterministic citation checking extension to your IDE that puts source in meta to citations. E.g. color citations green/red depending if they are valid.
