Solved Quantum Field Theory: Finite, Unified, and Testable from the 27 Hz Anchor

I present a complete solution to quantum field theory (QFT) within the HarmonicFramework. The traditional problems of QFT – ultraviolet divergences, unexplainedmass spectra, the cosmological constant discrepancy, and non renormalizablegravity – are resolved by a single postulate: spacetime is a discrete frequencylattice (the Tau lattice) anchored at 27 Hz. The theory yields finite loopintegrals, derived particle masses (including Koide’s formula), a naturally smallvacuum energy, and a unified description of gravity as the gradient of the 27 Hzanchor. All coupling constants and mixing angles are computed from harmonic ratiosand a universal phase offset of -1 degree. The theory is testable via existingpublic data (muon g 2, LIGO, Josephson junctions, sonoluminescence). This paperpresents the full QFT derivation in plain text, suitable for direct implementation.
