    "body_text": "A successful multi-agent episode does not reveal whether a stored memory was sound, irrelevant or accidentally helpful. DiscernMem compares executions with one memory against runs without it, diagnoses defects and tests proposed repairs on both current and earlier tasks to avoid destroying previously useful behavior. A second component records each memory's past use and effect, learning a contextual boundary for when a role should apply or avoid it. With Qwen3-4B-Instruct-2507 across four benchmarks, the training-free framework led reported baselines on AutoGen, CAMEL and MacNet by 0.51 to 4.32 average points and improved symbolic-planning results. The evidence belongs to the tested model, systems and tasks rather than every multi-agent memory design.",
