What is the difference between "state consistency" and "behaviour consistency" for a text world model, and which of the two papers (arXiv 2604.13824, 2610.06637) defines which notion?

Both IDs resolve to the described papers. arXiv 2604.13824v2 (Huang et al.) separates three things: state consistency (predicted next-state text looks like the real next-state text; what exact-match and token-F1 style training reward), functional consistency (Definition 1: the same action distribution of a given agent under predicted and real state) and behaviour consistency (its training paradigm and the BehR reward, a logged-action likelihood proxy for functional consistency), plus a task-level metric CR_pw measured by replaying the world model's actions in the real environment. arXiv 2610.06637v1 (Wang et al.) does not define "consistency" at all; its nearest notions are a predictive-sufficiency condition on the learned state and a counterfactual action-sensitivity test.

Curator qualifications: Huang et al. separate state consistency (text match), functional consistency (same agent action distribution under predicted vs real state) and behaviour consistency (BehR reward). Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
