A note on prismatic sites for p-quasisyntomic rings

Let $p$ be a fixed prime number and let $R$ be a $p$-quasisyntomic ring. In this note, we provide conditions for objects in the absolute prismatic site $R_{\text{Prism}}$ to cover the final object in $\text{Shv}(R_{\text{Prism}})$. More precisely, we introduce in $R_{\text{Prism}}$ the so-called transversal objects, with which coproducts exist in $R_{\text{Prism}}$. Immediately generalizing this, we introduce the so-called relatively quasiregular semiperfectoid covers of $R$, whose prismatic cohomology (of $\delta$-pairs, in the sense of Antieau-Krause-Nikolaus) would produce in $R_{\text{Prism}}$ objects with which coproducts exist.
