In addition, we introduce a benchmark suite for numerical TOHTN planning, providing a first common basis for evaluation in this setting. It comes from a paper posted to arXiv on 4 September 2026. While HTN planning has received significant attention in recent years, support for numerical reasoning remains very limited. In this paper, we investigate numerical Totally-Ordered HTN (TOHTN) planning and show how standard SAT-based encodings can be naturally extended with SMT to handle numeric fluents. Experimental results show that this simple encoding already constitutes a competitive baseline. This work opens the way to more expressive approaches to HTN planning.
