oa::ml::loss::bce

Compute mean binary cross entropy over matching FP32 probability matrices. Predictions use the donor’s [1e-7, 1 - 1e-7] numerical clamp. Targets are treated as detached; reverse mode differentiates only the prediction. Errors Returns an error for empty, mismatched, non-FP32, or cross-engine inputs, or when allocation or runtime recording fails.
