ArXi:2601.17593v2 Announce Type: replace Recent progress in large language models has renewed interest in how multi-step reasoning is represented internally. While prior work often treats reasoning as a linear chain, many reasoning problems are naturally modeled as directed acyclic graphs (DAGs), where intermediate
