    "body_text": "DynaHarness gives a robot agent a shared execution contract: a slow reasoning component proposes capabilities, while a fast controller grounds commands, refuses unresolved actions, substitutes skills and requests replans. Failure attribution points to reusable capabilities or execution mechanisms, and paired regression checks decide whether revisions enter the library. On 800 new LIBERO-Pro initial states, the authors report 75.2% success versus 17.5% for the frozen policy. The result is benchmark evidence, not a general safety guarantee.",
