+  description: wav2vec 2.0 (XLS-R 300M) self-supervised front-end fine-tuned end-to-end with a Nes2Net-X (Nested Res2Net TDNN)
+    back-end for speech anti-spoofing. The nested Res2Net structure couples multi-scale residual groups with squeeze- excitation,
+    replacing dimensionality-reducing necks; mean temporal pooling + linear classifier. Only ~0.51M back-end params. Official
+    Nes2Net-X single checkpoint (ASVspoof2021 LA 1.73% / DF 1.65% EER as reported), trained on ASVspoof2019 LA with RawBoost,
+    FP32, deterministic first-64600-sample window (no random crop).

+notes: XLS-R 300M (wav2vec 2.0) front-end + Nes2Net-X back-end, the single (non-averaged) checkpoint from Liu-Tianchi/Nes2Net_ASVspoof_ITW
+  (Nes_ratio [8,8], SE_ratio [1], pool_func 'mean', dilation 2). Architecture is built from the base xlsr2_300m.pt model config,
+  then every weight is overwritten by the fine-tuned checkpoint. Deterministic first-64600-sample window (no random crop),
+  matching the source data_utils_SSL.py::pad used at eval (default --test_protocol 4sec). score = output logit for class 1
+  (bona fide); higher = more bona fide. Back-end params ~0.51M; params_millions reports the full deployed model incl. the
+  XLS-R front-end.
