+  description: AntiDeepfake detector (XLS-R 2B self-supervised backbone) post-trained
+    for deepfake speech detection with RawBoost data augmentation (default variant);
+    head = AdaptiveAvgPool1d + Linear(D,2), score = real logit. Released by nii-yamagishilab
+    (arXiv:2506.21090). Evaluated with a deterministic first-4 s window + batching
+    (NOT the paper's whole-utterance protocol).
