In inflationary magnetogenesis with inhomogeneous inflaton perturbations, the claimed new scale-invariance conditions and spectral-index shifts rest on a derivation step that treats integration constants as time-dependent and drops a same-order source term.

The Impact of Inhomogeneous Perturbations of the Inflaton on the Cosmological Primordial Magnetic Field
In inflationary magnetogenesis with inhomogeneous inflaton perturbations, the claimed new scale-invariance conditions and spectral-index shifts rest on a derivation step that treats integration constants as time-dependent and drops a same-order source term.
