Crate tenferro_internal_ad_surface 

Internal implementation crate. Not a stable public API.

tenferro now treats tidu::Value<DynTensor> as the only source of truth for reverse-mode metadata. This crate provides the thin dynamic tensor façade and surface-level grad/backward helpers built on top of that carrier.
