+  description: 'Spoof-SUPERB linear-head detector (Ali et al., 2026) over a frozen UniSpeech-SAT Large
+    (24 layers, 1024-d; s3prl `unispeech_sat_large`): the s3prl Featurizer softmax-weights all 25 hidden
+    states (24 transformer-layer inputs + the encoder output; no per-layer norm), then Linear(1024,256)
+    -> mean pooling over frames -> Linear(256,2). Only the layer weights, projector and classifier are
+    trained (ASVspoof 2019 LA train, 50 epochs, SWA); the authors'' released head with the s3prl converted
+    upstream. Input as the authors'' scoring code: 16 kHz, first 64600 samples (shorter clips tiled),
+    the upstream''s own per-utterance waveform layer-norm; FP32. score = logits[:,1] (bona fide).'

+  (no download); head loaded per backends.py (all 5 trained tensors present, nothing unexpected; upstream
+  loaded strict by s3prl). Verified bit-identical (max |d| = 0) to the authors'' code on In-the-Wild clips,
+  and within <0.01 logit of the authors'' published per-utterance In-the-Wild scores (issf/spoof-superb-scores)
+  when fed the original float wavs; the Arena''s PCM_16 FLAC copy of In-the-Wild moves logits slightly
+  more. Trained on ASVspoof 2019 LA train only (the Arena''s ASVspoof2019_LA is the eval split) -> no
+  trained_on entries. Self-reported EER% (paper main table): 19LA 1.35 / 21LA 8.82 / 21DF 7.59 / ASVspoof5
