DESCRIPTION:In this talk\, I will present our &ldquo\;2D CFT factory\,&rdq
 uo\; a framework for systematically generating critical lattice models fro
 m topological field theories (TFTs) defined by spherical fusion categories
 . Critical points are extracted directly from categorical data and validat
 ed through the categorical-symmetry-preserving loop tensor renormalization
  group. This predictive approach not only reproduces well-known examples\,
  such as the 8-vertex model from the $A_5$ category\, but also uncovers ne
 w cases\, including those built from the Haagerup category&mdash\;highligh
 ting a vast landscape of critical theories yet to be explored.
