The Unary Field Theory (UFT) predicts specific anomalies in the low-ℓ CMB temperature power spectrum: a ∼5% power deficit at ℓ=2–5 and a ∼3% excess at ℓ=10–20, relative to ΛCDM. These arise from the integrated Sachs-Wolfe (ISW) effect of large-scale κt flow shear—spatial gradients in the residual flow fraction sflow (x) on cosmological scales (∼300 Mpc). The same mechanism produces "empty gravity wells" (Paper IV) and the Hubble flow dipole (Paper IX). The κt shear parameter β ∼ 4×10⁻³ determines the anomaly amplitudes. The UFT also predicts alignment of low-ℓ multipoles with the supergalactic plane, perpendicular to the CMB dipole. Observational tests include LiteBIRD/CMB-S4 low-ℓ polarization analysis and cross-correlation with DESI/LSST galaxy surveys. Planck 2018 data show ∼2–3σ consistency with these predictions. This is UFT Prediction Paper XVII; the unified framework is in the main paper: Zou (2026), doi: 10. 5281/zenodo. 21186809.
