    "body_text": "The global-coherence study formalizes a failure in which every agent's local choice is valid but the combined action violates a shared constraint because decisive state is invisible. In controlled tests, a frontier model scored 40 of 40 when the deciding event was visible, fell to 12–17 of 40 when it was hidden, and returned to 40 of 40 when one authoritative fact was restored. On a shared-budget task, ordinary teams exceeded the limit in all five runs; a visible live count still left four violations, while commit enforcement left none. The results support the paper's architectural claim for its tested settings: models may propose, but a harness that owns shared state must govern commit.",
