NeuralCFD / AB-UPT: geometry-separated anchored CFD surrogates

What changed

Evolved GP-UPT geometry-preserving encoding into anchored, multi-branch UPT decoders for surface/volume fields, including an explicit divergence-free output formulation; a later report evaluated existing architecture on SHIFT automotive/aerospace data.

Scientific scope

Evolved GP-UPT geometry-preserving encoding into anchored, multi-branch UPT decoders for surface/volume fields, including an explicit divergence-free output formulation; a later report evaluated existing architecture on SHIFT automotive/aerospace data. One original-preprint/revised-method/application family. First v1 is GP-UPT with6authors; v4 AB-UPT has7and changed architecture, not backdated as the February formulation. Additional application report states no major architecture change. Surrogate errors/speedups are finite numerical comparisons, not exact NavierStokes solutions or universal physical constraints.
