Hosted MOFFlow-2 csp certification: authors' predict (task=csp) on the first 500 entries of the released test split (num_samples=5, seed=123), evaluated with the authors' RMSD code at stol 0.5 and 0.3, k=5 and k=1. All four match rates fall within the binomial 95% CI of the paper's Table 2 values (arXiv:2505.17914). Run fc-01M2DJ1WDRY1JPR01SF4F1HN5Z, 2026-09-13.
