Built from 542 quality-controlled factual questions into 6,504 episodes with tool returns of known correctness, across five open-weight 7-9B models (arXiv 2608.26295). Models follow a correct tool 86.0-93.1% of the time and repeat the tool return in 78.4-86.0% of cases where both the tool and the model are wrong. No cross-model ordering survives three instruction-wording variants with content held fixed, so tool-trust behavior is unstable to prompt phrasing. Practical read: a poisoned tool output beats the model's own correct knowledge roughly nine times in ten.
