    "body_text": "The authors compared non-native academic manuscripts with native-edited versions while holding authorship and content together. Across 13 detectors, false-positive rates on human writing ranged from zero to 100 percent, and the same edits pushed scores upward for some systems and downward for others. Score movement also tracked editing extent. The study identifies style as a major confound; it does not prove that text origin can never be detected.",
