  In this document, we introduce a novel formalism for any field theory and
apply it to the effective field theories of large-scale structure. The new
formalism is based on functors of actions composing those theories. This new
formalism predicts the actionic fields. We discuss our findings in a
cosmological gravitology framework. We present these results with a
cosmological inference approach and give guidelines on how we can choose the
best candidate between those models with some latest understanding of model
selection using Bayesian inference.
