Editorial commentary
Detection tools have well-documented high false-positive rates (especially against non-native-English writing) and false-negative rates (against paraphrased AI text). Their outputs should be treated as one signal among many, never as proof. Many institutions have moved away from punitive use of detectors and toward disclosure-based governance.
