Kev 4B is a small open-weight decision model from Jared Palmer — a LoRA adapter and pointer head on Qwen3.5-4B-Base. Send state and typed questions (noul / choice / score) and get a calibrated probability per question in one forward pass, not generated text. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).
