Steady diffusion-limit reference; finite-flux nonlinear M1 can have a model error floor.
Adaptive leaf-volume norms are reported without uniform-grid convergence orders.

AMR levels 2–3; 90112 active cells; finest equivalent 64³
AMR: positive-side cells touching z=0, projected as constant leaf averages. Centers have z=leaf_dx/2; the ray similarly touches y=0. This is not a common cell-center plane. Raw CSV preserves native cells; display CSV repeats coarse values on finest pixels, retaining source dx/z. Full-volume norms use actual leaf volumes; uniform-grid convergence orders are not reported.

Radiation conservation
R = Q(t) − Q(0) + B(t) − S(t). B is cumulative outward transport; S is the signed source change. Flux integrals divided by c² give radiation momentum. All plotted totals and residuals are fractions of the fixed initial magnitude |Q(0)|. Zero/negligible initial flux (|Q(0)| ≤ 64ε c|E₀|) uses the labeled fallback c|E₀|. Neither denominator changes during the run.
