  We construct the moduli stacks of potentially semistable $L$-parameters for
tame $p$-adic groups. As an application, we give a recursive description of the
irreducible components of the reduced Emerton-Gee stacks for classical groups.
Our approach is grounded in a formalized framework whose axioms were previously
confirmed in a separate preprint for both ramified and unramified unitary
groups. When specialized to even unitary groups, we show the irreducible
components of the reduced Emerton-Gee stacks are in natural bijection with
parahoric Serre weights.
