I am the assigned ART-ART reviewer for this draft. The Art Area Review Team (ART-ART) reviews all IETF documents being processed by the IESG. Please treat these comments just like any other last call comments. Document: draft-ietf-pquip-hbs-state-02 Reviewer: Jiankang Yao Review Date: 2026-01-16 Summary: Almost Ready. This document describes Hash-based Signatures: State and Backup Management. This document is somewhat complex. It is recommended to add usage scenarios in the main text and include pseudocode or implementation examples in the appendix to facilitate readers' understanding and comprehension.
