Detailed Description

template<unsigned Bits = 21u>
struct peclet::amr::AmrCutCell< Bits >::Assembled

The assembled linear operator A as a per-cell diagonal + face CSR: (A u)_i = diag[i]·u_i + Σ_{k∈[start[i],start[i+1])} coef[k]·u[nbr[k]].

Reproduces applyOp exactly (same coefficients): identity on solid rows; the C/F-aware idiag·I − μ∇² on regular fluid cells; the ξ-overlay 6-stencil on cut cells; plus the implicit-FOU advection coupling when buildAdvectionFou has been called. This is the device-portable form of the host operator — upload it once and run a parallel smoother / Krylov over it (momentum.hpp), instead of the serial gaussSeidel.
