 ## How to Use
+> **Breaking change (May 2026):** `model.predict()` now returns raw "Yes" logits instead of sigmoid'd probabilities in `[0, 1]`. Rankings are unchanged. To recover the previous 0-1 score, apply `(scores / 5).sigmoid()` — see the example below. Loading no longer requires `trust_remote_code=True`; passing it is harmless.
