A Structural Reduction of the Riemann Hypothesis to Critical-Line Completeness

This preprint develops a structural reduction and falsification framework for the Riemann Hypothesis (RH), without claiming a proof of RH. A nontrivial zero is parametrized as ρ=21+δ+iγ, so that RH requires δ=0 for every nontrivial zero. The manuscript examines and explicitly separates several structures that are insufficient by themselves to exclude off-critical zeros, including functional-equation symmetry, symmetric Hadamard zero quartets, prime-side positivity, explicit-formula growth signatures, and spectral analogies. Returning to the historical order of Riemann's 1859 reasoning, the paper compresses the unresolved problem into the zero-counting deficit D(T)=N(T)−N0(T), where N(T) counts all nontrivial zeros up to height T, with multiplicity, and N0(T) counts those lying on the critical line ℜ(s)=1/2. Thus RH is equivalent to D(T)=0 for all T. The final reduced question is whether an intrinsic identity, monotonicity principle, topological constraint, or completeness theorem for the Riemann ξ-function—without assuming RH or an RH-equivalent criterion—can force the global zero-counting/winding count to be completely realized by critical-line zeros. The manuscript also presents carefully separated structural analogies with systems pathology and the Planetary Common State (PCS) residual framework. These analogies are heuristic and are not used as mathematical evidence for RH.
