Eliminate the entire mixed_precision runtime indirection layer: - Delete crates/ml-core/src/mixed_precision.rs (training_dtype, ensure_training_dtype, align_dim_for_tensor_cores) - Inline ~100 call sites across 130 files to constants: training_dtype(&device) → candle_core::DType::BF16 ensure_training_dtype(x) → x.to_dtype(candle_core::DType::BF16) align_dim_for_tensor_cores(x, &device) → (x + 7) & !7 - Remove re-exports from ml-dqn, ml-supervised, ml lib.rs - Clean config/toml/json/shell references No CPU/Metal training path exists — BF16 is the only dtype.
