Separate the broader proposed action, an assumed cosmological parameterization and the released scalar–electromagnetic example.
Current interpretation
CPL density uses exp(−3wₐz/(1+z)). The displayed k,C₀→w₀,wₐ map is a chosen parameterization. A B(C)F² term alone does not establish n=1+2βC or the advertised lensing multiplier.
Model scope and provenance
The released example uses B(φ)=exp(gφ), a polynomial potential and a flat periodic 2+1 reduction. It is not a full metric evolution, screening model or SI calibration of the broader proposal.
Conditional mathematics and numerical reference curves, not a cosmological fit.
Historical sources remain separately identified; availability is not a safety endorsement.
