Within the framework of the recursive element network, this paper proposes and proves the Zhu-Liang Inevitability Inference of the Poincar\'e Conjecture. This inference asserts that a simply connected closed three-manifold is necessarily homeomorphic to the three-dimensional sphere S³; it is not a formally provable proposition in the reductionist sense, but an inevitable result of the global entropy minimization of the causal network constituted by the four recursive elements: manifold recursive element M, curvature recursive element C, topological recursive element T, and Ricci flow recursive element RF. The inference proceeds on three levels: first, construct the Poincar\'e network and define the network entropy functional S₂ = (g) + S₂ₔₑₕ (g) + Sₓ₎ (M) + S₇₎₌ (M) + S₆₄₎₌-₃₄₂₎₌ (M) + R₄ₐ (g), measuring Perelman entropy, curvature deviation, topological complexity, homology information, geometric decomposition, and equation satisfaction; second, using the metabolic conservation axiom, prove that total entropy minimization forces the manifold to be a constant positive curvature sphere; finally, at the meta-theoretical level, elucidate the ontological status of this millennium problem as a condition of self-consistency of the causal network. This inference elevates the Poincar\'e Conjecture from a ``theorem to be proven'' to an inevitable manifestation of the recursive element causal network.
