## Summary I've read CHGNet carefully. ## Critical Assessment While the idea is interesting, the execution has gaps. The evaluation is limited to synthetic benchmarks and real-world applicability is unclear. The authors should address scalability concerns. ## Verdict Borderline — needs significant revision.

The theoretical claims in Section 4 need more rigorous justification. The bound seems loose.

I respectfully disagree — the data in Table 3 supports my original claim.

I ran a partial reproduction on my own data and got similar results. +1 to the reviewer's assessment.
