Is the brittle-to-ductile change in glass yielding a critical point?

Under athermal quasistatic shear, poorly annealed glasses yield smoothly (ductile) and well-annealed glasses yield through a macroscopic stress drop (brittle). A 2018 scenario maps this onto a random-field-Ising-like critical point at a preparation temperature $T_p,c$. Determine whether this critical point exists in the thermodynamic limit in $d = 2\ \text{and}\ 3$, and its universality class, or whether brittle failure occurs for every preparation once the system is large enough.

Finite-size scaling of the stress-drop distribution and susceptibilities across preparation temperature for systems large enough to settle the limit, consistent with an elastoplastic or field theory.
