Abstract We introduce the Global Odd Tower (GOT), a finite-depth structural coordinate system for odd integers based on patterns of 2-adic valuation arising from the accelerated odd Collatz map. The framework assigns to each odd integer a structural coordinate (H,L), or equivalently a finite-depth profile \Phi_D, without assuming convergence of Collatz orbits. Within this coordinate system, classical arithmetic constraints are translated into geometric admissibility conditions on structural cells. As a critical test case, we examine odd perfect numbers. Perfectness imposes an extreme parity rigidity, forcing all prime divisors into a single confined structural corridor at the lowest level of the tower. We show that this corridor confinement is incompatible with the lineage compatibility laws governing the GOT. In particular, the asymmetric closure required by the unique odd-exponent prime power cannot be realized within the finite-depth hierarchy. As a consequence, the structural cell corresponding to odd perfect numbers is empty within the Global Odd Tower. The argument is purely structural and does not rely on analytic estimates, computational bounds, or unproven conjectures.
