This is the second paper in a series of the three works. A complete real-space mechanical model of the Z^0 and W^± intermediate vector bosons is established within a granular space substrate (tessellattice). By applying inertomagnetic unification, this framework demonstrates that electroweak mass splitting is a mandatory consequence of localised geometric constraints. For the neutral Z^0 boson, the co-rotating core is compressed by the internal massotension field (inerton carriers) and local photon-mediated Coulomb fields, yielding a solitary eigenvalue at 91.19 GeV. For the charged W^± boson, the net charge triggers a coherent structural vortex whose velocity-dependent Poincaré-Appell magnetic torque achieves full parity with the mechanical inerton tension, doubling the potential barrier to lock a unique eigenvalue at 80.38 GeV. The spatial derivative of the square-root high-energy operator naturally proves an asymmetrical centripetal force scaled by the Lorentz factor, resolving the Ehrenfest paradox within a material space substrate. At the speed-of-light propagation limit, this configuration reveals an energy equipartition rule, such that each constituent quark core carries exactly one-quarter of the total boson mass: 22.80 GeV for Z^0 and 20.10 GeV for W^±, and the vortex diameters are 4.23×10^(-18) m for Z^0 and 9.82×10^(-18) m for W^±. Besides, probabilistic quantum decay is replaced by a deterministic mechanical clockwork threshold. The physical vortices exhibit a minor fractional phase-lag, locking lifetimes at N_Z≈5.86 and N_w≈3.07 rotations. Mimicking the hydrogen spectrum’s fine structure, this deficit represents direct, measurable sub-microscopic friction born from the non-commensurable overlapping of the Compton, polarisation, de Broglie, and inerton cloud scales.
