Decision model
Clef is not a chat model. A request is a state plus a schema of typed questions (noul, choice, score). One prefill returns a probability for every allowed option. joint_head.safetensors is the original BF16 joint schema head, copied unchanged, with joint_schema_model.py and joint_head_config.json. Text generation does not run that head.
Precision
Vision, norms, token embeddings, and the LM head stay at source precision. The joint schema head is not part of the language index and is not quantized. This package is development evidence. It is not a Decision Index certificate and it does not claim parity with the upstream BF16 checkpoint.
