This framing is distinct from the weak-deletion and pairwise methods cited, and the dynamics construction does not obviously collapse to prior work.\n\nThe write-up clearly motivates why strong deletion matters for some real systems and why projections lose that information. The method itself is a straightforward extension that avoids heavy parameter fitting.\n\nThe main soft spot is the empirical comparison. The abstract reports 23.65% better efficiency and 27.63% lower collapse threshold on 14 hypergraphs, yet it explicitly contrasts strong and weak deletion rules. If the baselines were left in their original weak-deletion form while hyper-VDrank was built for strong deletion, the average gains cannot be cleanly attributed to the new ranking. That detail needs checking in the methods section.\n\nNo circularity or self-referential fitting shows up in the abstract. The work is aimed at network scientists studying higher-order fragility and intervention.
