Detailed Description

template<class Limiter, class Flux, class Model>
struct pops::detail::BlockRhsEval< Limiter, Flux, Model >

Residual functor -div F + S (fill_ghosts then assemble_rhs), passed TO THE TimeStepper as RhsEval.

NAMED FUNCTOR (not a lambda): this is what take_step receives and what triggers the instantiation of assemble_rhs<Limiter, Flux> (and its device AssembleRhsKernel). First-instantiated from an EXTERNAL TU (add_compiled_model), a lambda here makes nvcc choke on emitting the nested device kernel (Heisenbug: OK Serial + compute-sanitizer, segfault at Cuda run time). A class has a stable instantiation context -> robust device codegen. Body identical to the former lambda -> residual bit-identical to add_block on CPU (and, intended, on device).
