Function evaluate_weights_binding_with_loaded_hash

Evaluate binding after the provider-side loaded-weight digest has been recomputed.

Hosted or protocol adapters that cannot expose loaded model bytes pass an error here. The kernel maps that unavailable state to a schema-level refusal and never falls back to caller-supplied hashes.
