Use an explicit, constraint-consistent background example with increasing redshift and checked luminosity distances.
Current interpretation
The current example removes the reversed interpolation grid and invalid-distance clamp. H follows the Friedmann constraint, not a relaxation rule; the Klein–Gordon equation includes d ln H/dN.
Model scope and provenance
This is a standard, separately defined cosmology example—not a reproduction of historical MCMC pipelines, the complete framework, or the released fixed-metric scalar–Maxwell model.
