This paper completes the Hydrodynamic Quantum Gravity (HQG) series by addressing the remaining theoretical gaps in a framework that proposes empty space behaves like a superfluid plenum belonging to the ³He-A universality class. Previous papers derived gravity as acoustic radiation pressure (Bjerknes force), electromagnetism from pressure gradients and vorticity, and quantum mechanics from Madelung hydrodynamics. This fifth paper extends the framework to encompass nuclear forces, mass generation, tensor gravitational waves, and the spin-statistics theorem. This paper synthesises recent research in condensed matter physics, stochastic electrodynamics, and topological field theory to address theoretical gaps in the Hydrodynamic Quantum Gravity framework. The synthesis was developed with AI research assistance (Claude, Anthropic) to survey literature and articulate mechanisms. The underlying theoretical framework and physical interpretations are the author's own. Key Results: QCD Confinement: Quark confinement emerges from dual superconductivity, where the vacuum condensate of magnetic monopole defects confines chromoelectric flux to vortex tubes via the dual Meissner effect, producing the linear confining potential V(r) = σr. Electroweak Symmetry Breaking: The Higgs mechanism is identified as a literal superfluid phase transition, with the 125 GeV Higgs boson corresponding to the amplitude mode (breathing oscillation) of the vacuum condensate. Chirality and parity violation emerge naturally from the intrinsic angular momentum of the chiral ³He-A vacuum. Electron Mass: The electron mass (0.511 MeV) is derived as resonant interaction between an oscillon defect and the electromagnetic zero-point field, with inertia arising from hydrodynamic added mass and ZPF drag. Tensor Gravitational Waves: The apparent conflict between scalar fluid dynamics and LIGO's tensor wave observations is resolved by identifying gravitational waves with Transverse Zero Sound—a shear mode unique to quantum Fermi liquids that carries spin-2 quadrupole polarisation. Spin-Statistics Theorem: Fermionic statistics and Pauli exclusion are derived topologically from the winding numbers of half-quantum vortices, with exclusion arising as geometric obstruction preventing identical twisted defects from occupying the same state. This paper is the fifth in a series. Companion papers address experimental predictions (Harrison's Theorem), gravitational foundations, electromagnetic derivation, and quantum mechanical emergence.
