This paper develops the algebraic foundation required to build a Zariski-type geometry for \emph{ commutative ternary $\Gamma$-semirings}, where multiplication is an inherently triadic, multi-parametric interaction $(a,b,c,\gamma)\mapsto\{ abc\}_{ \gamma}$. Rather than treating triadic multiplication as an optional variation of binary algebra, we adopt it as an \emph{ algebraic necessity} for modeling systems whose elementary interactions are intrinsically three-body and whose operational modes are indexed by parameters $\Gamma$. We construct the prime spectrum $\Spec_{ \Gamma}(T)$ and its Zariski topology, prove functoriality, and build the structure sheaf $\Ocal_{ \Spec_{ \Gamma}(T)}$ via local fraction descriptions that must simultaneously respect triadic associativity and the sheaf gluing axioms. A key technical point is ensuring that local representations by ternary-parametric fractions glue uniquely, despite the absence of a binary product and despite the parameter dependence of the multiplication law. We then define sheaves of $\Gamma$-modules, quasi-coherent sheaves associated to algebraic modules, and the cohomology groups $H^i(X,\Fcal)$ as derived functors of global sections. Finally, we give a concrete finite \emph{ structural example} (a ternary $\Gamma$-version of $\mathbb{ Z}/n\mathbb{ Z}$) and compute its $\Gamma$-spectrum explicitly, thereby exhibiting nontrivial spectral behavior in a fully finite setting.
