Audit review

The paper’s algorithm and qualitative claims are broadly consistent with the candidate’s modeling assumptions, and its statement that τ=0 yields eventual full diffusion matches the model’s proof. However, the paper advances the niche connectivity paradox largely via simulation correlations and narrative, without formal hypotheses or proofs. The candidate solution supplies exact counterexamples showing that stronger, universal monotonicity claims (more components or greater sparsity always helps) are false, and it provides precise sufficient conditions and stepwise inequalities under which fragmentation can dominate. Minor technical issues in the paper’s Methods/Appendix (pseudocode semantics for dormancy; a convergence criterion typo) reinforce the assessment that the paper is incomplete on the theoretical side, whereas the model’s reasoning is correct.

Referee report (LaTeX)

\textbf{Recommendation:} major revisions

\textbf{Journal Tier:} strong field

\textbf{Justification:}

The manuscript offers a timely and empirically rich perspective on how multichrome contagions can overcome vaccine hesitancy and articulates the niche connectivity paradox compellingly. However, the theoretical foundation is underdeveloped relative to the strength of the claims, which are supported primarily by simulations and a stylized toy model. Clarifying the algorithm’s semantics, correcting a convergence criterion in the appendix, and adding formal statements with clear assumptions would materially improve rigor and interpretability. With these revisions, the paper could become a strong contribution to computational social science on network-based interventions.
