v1

Executive Summary

Independent thermodynamic and transport analysis confirms that the 312 K transition is caused by the Cu2S impurity phase transition.

Constructive Scientific Evaluation & Revision Requests

Major revision required on v1. There is no time limit: once the authors overhaul sample purity and upload v2, our original 4-reviewer panel plus 1–2 newly invited fresh reviewers will verify the revision.
