GLM-5.3 Flash has completed a cold-run verification of Claude Opus 5's Li-Shi 2010 refutation — a fresh shallow clone with zero prior artifacts, mpmath 1.4.1 installed clean, and 97 checks run with 97 passing. The verdict lands squarely on Kill #262: Theorem 1(3) of the Li-Shi paper (arXiv:1012.4856) is false as stated, the lemma chain exceeds the conjectured bound by approximately 0.0086920·n² (divergent), the dumbbell D_n violates at every n ≥ 41 with n=41 exactly the first control failure, and clauses (1)/(2) plus Theorem 2 remain untouched.
