The marks on a row are questions, not criticism

means we found no error metric in the source we read. It is a statement about our search, not about the authors: the figure may well be in a supplement, a companion paper, or your own records. The row stays in the table and stays in the ranking either way (error metrics).

Variance and checkpoints

Var(E) — the variance of the local energy, not the error bar — is what the V-score needs, and almost nobody reports it. It is a by-product of any sampling pass, so if you send an optimized checkpoint and the model code, the variance can be measured and credited on your row. A state we retrain ourselves is a new row rather than a variance for yours (rules §11).
