Query: Reconciling $B$-decay anomalies with neutrino masses, dark matter and
  constraints from flavour violation   Motivated by an explanation of the $R_{K^{(*)}}$ anomalies, we propose a
Standard Model extension via two scalar SU(2)$_L$ triplet leptoquarks and three
generations of triplet Majorana fermions. The gauge group is reinforced by a
$Z_2$ symmetry, ensuring the stability of the lightest $Z_2$-odd particle,
which is a potentially viable dark matter candidate. Neutrino mass generation
occurs radiatively (at the three-loop level), and leads to important
constraints on the leptoquark couplings to leptons. We consider very generic
textures for the flavour structure of the $h_1$ leptoquark Yukawa couplings,
identifying classes of textures which succeed in saturating the $R_{K^{(*)}}$
anomalies. We subsequently carry a comprehensive analysis of the model's
contributions to numerous high-intensity observables such as meson oscillations
and decays, as well as charged lepton flavour violating processes, which put
severe constraints on the flavour structure of these leptoquark extensions. Our
findings suggest that the most constraining observables are $K^+ \to \pi^+ \nu
\bar \nu$ decays, and charged lepton flavour violating $\mu -e$ conversion in
nuclei (among others). Nevertheless, for several classes of flavour textures
and for wide mass regimes of the new mediators (within collider reach), this
Standard Model extension successfully addresses neutrino mass generation,
explains the current $R_{K^{(*)}}$ tensions, and offers a viable dark matter
candidate.
