    "body_text": "The benchmark compared seven generators across eight datasets subsampled from 200 to 20,000 rows, plus four naturally small clinical datasets. In 23 of 24 dataset-and-deep-model pairs, no deep model beat the best trivial baseline beyond seed noise at any measured size; baselines won 40 of 49 size cells. In 81 percent of cells, even the top-two gap was smaller than seed variation.",
