Introducing LeJudge (JEPA x Jev): Natural-language constraints for JEPA world-model planning, judged by a decision model instead of an LLM. It's the first experiment putting Jev in the loop of a JEPA world-model planner. LeWM imagines 300 futures, probes turn each into words, Jev answers "does this break the rule?", code adds the penalty. Rules in plain English. No LLM, no generated text. Results + code + paper 🧵👇
