NOTICE Cost-Aware Protocol Routing: Matched Protocol Outcomes This dataset accompanies: "LLMs Can Predict Failure Risk, But Struggle to Predict Which Collaboration Protocol Pays Off: Cost-Aware Protocol Routing Across Reasoning Tasks" Chih-Hsuan Yang, Jingyan Jiang, Cheng-Hau Yang, Vikram Vasudevan, Huihuo Zheng, Venkatram Vishwanath, Rajeev Thakur. EMNLP 2026. arXiv:2608.14927 ATTRIBUTION FOR UPSTREAM BENCHMARKS The derived outcomes in this release were measured on problems from the following benchmarks. Their problem text is NOT redistributed here; only stable identifiers are. Anyone who reconstructs the problems from upstream must comply with the upstream license and cite the upstream work.

LAB-Bench ships a canary string and an accompanying do-not-train request. This release contains no LAB-Bench problem text, options, or answers, so it carries no canary; do not use the identifiers here to assemble a training corpus that would violate that request. MaScQA (CC-BY-NC-SA-4.0) is NOT part of this release. It has no matched Gemma run and is excluded from the paper. Its NonCommercial terms are also incompatible with this release's licensing.
