POPS_HD Model::State	pops::load_state (const ConstArray4 &a, int i, int j)
	load_state<Model>: reads Model::n_vars scalars at (i,j) from an Array4.

template<int NComp = kAuxBaseComps>
POPS_HD Aux	pops::load_aux (const ConstArray4 &a, int i, int j)
	load_aux<NComp>: reads NComp components of the auxiliary from an Array4 at (i,j).

Detailed Description

Model/state/aux access layer of the Cartesian spatial operator.

CONTRACT: how the spatial operator reads a model and its data.

DiffusiveModel: optional concept (model.diffusivity() -> nu); the Fickian flux F = -nu grad U is added to the hyperbolic flux when present (face_flux.hpp, cartesian_operator.hpp).
SourceFreeModel<M>: adapter that zeroes the source (explicit IMEX half-step).
load_state<Model>: reads the conservative state from an Array4 (POPS_HD).
load_aux<NComp>: reads the auxiliary (phi, grad, extra fields) (POPS_HD).

This module carries no grid loop: every entry is POINTWISE (POPS_HD) or a compile-time model adapter. It is the bottom of the spatial/ dependency DAG (depends only on core/).
