  We analyze the consistency of electroweak breaking, neutrino and dark matter
phenomenology within the simplest scoto-seesaw model. By adding the minimal
dark sector to the simplest "missing partner" type-I seesaw one has a physical
picture for the neutrino oscillation lengths: the "atmospheric" mass scale
arises from the tree-level seesaw, while the "solar" scale is induced
radiatively, mediated by the dark sector. We identify parameter regions
consistent with theoretical constraints, as well as dark matter relic abundance
and direct detection searches. Using two-loop renormalization group equations
we explore the stability of the vacuum and the consistency of the underlying
dark parity symmetry. One also has a lower bound for the neutrinoless double
beta decay amplitude.
