Description
We study the emergence of approximate neutrino texture structures in the minimal scotogenic model using large-scale Casas--Ibarra parameter scans subject to dark matter and lepton flavor violation constraints. We show that phenomenological consistency conditions can dynamically induce approximate suppressions in specific entries of the neutrino mass matrix without imposing explicit flavor symmetries. In particular, the interplay between relic density, radiative neutrino mass generation, and lepton flavor violating observables naturally favors suppressions in the $(e\mu)$ and $(e\tau)$ sectors, while diagonal entries remain comparatively stable against cancellation. We further compare normal and inverted neutrino mass hierarchies, analyze reduced and full Casas--Ibarra parameterizations, and identify approximate scaling relations connecting dark matter and flavor observables. Our results indicate that nontrivial flavor structures may emerge as dynamical consequences of radiative neutrino mass generation and phenomenological constraints.
