Formulate a theory of fibered categories with base-induced symmetry actions
Develop a general mathematical framework for fibered categories equipped with symmetry actions arising from their base categories, specifically for the fibered category whose objects are schemes over arithmeticoids of a number field (the objects (X,L_ε)^{sch} in the category 𝔅𝓸𝓁𝒹 𝒮𝒸𝒽_L) with projection to the space of arithmeticoids (as in Equation (eq:proj-to-arithmeticoid)), so that global symmetries acting on the base (Galois, Frobenius, and multiplicative actions) are functorially realized on the total category.

Presently, I do not know of any general formulation of the theory of fibered categories equipped with symmetry actions given by their respective base categories.
