Quantum Spectrodynamics (QSD) is a theoretical framework that derives Standard Model gauge couplings from a single structural input: the [[5,1,3]] perfect quantum error-correcting code. The code determines two graphs - the complete graph $K_4$ (bulk exchange interactions) and the cycle graph $C_5$ (geometric dynamics) - from which three fundamental constants emerge: $$\text{Holographic bit density:} \qquad {H\kern-0.3em b}_4 = \frac{1}{4 \ln 2}$$ $$\text{Geometric strain:} \qquad \varsigma = \frac{3}{80\varphi^2}$$ $$\text{Spectral bond:} \qquad \varpi = \pi \varphi^2$$ From these, with zero free parameters and a single experimental input (the Planck mass), QSD derives: Symbol Observable QSD Prediction Experimental Value Agreement $\alpha^{-1}$ Fine structure constant $137.033$ $137.036$ $22$ ppm $\alpha_s(M_Z)$ Strong coupling at $M_Z$ $0.11781$ $0.1180 \pm 0.0009$ $0.16\%$ $\sin^2\theta_W$ Weak mixing angle $0.23122$ $0.23122 \pm 0.00003$ $< 0.01\%$ $m_H$ Higgs boson mass $126.7$ GeV $125.25$ GeV $1.3\%$ $E_{\mathrm{syn}}$ Syndrome energy $28.24$ GeV $\sim 28$ GeV* $0.2\%$ *CMS dimuon anomaly (CMS-PAS-HIG-20-009) The framework makes falsifiable predictions testable at the LHC.
