Researchers have introduced NormWorlds-CF, a novel environment designed for counterfactual normative reasoning in executable rule worlds, verified by a deterministic solver. This system provides detailed outputs such as final answers, proof certificates, and argument statuses, enabling robust evaluation without relying on LLM judges. The benchmark includes staged SFT diagnostics and a paired-world task, where a new reward mechanism called metamorphic-relation GRPO (MR-GRPO) was developed to improve performance on structured-change tasks by offering partial credit for relation families and solver-visible change fields.
