EUT 4.4 presents a complete, inflation-free cosmological model based on a single ultralight axion (m_a = 1.5×10⁻²¹ eV) serving as Fuzzy Dark Matter. Dark matter arises via the standard vacuum misalignment mechanism. Primordial black holes with abundance f_PBH 60 e-folds of expansion. All major parameters (Ω_DM ≈ 0.25, effective late-time acceleration, σ₈ ≈ 0.76, S₈ ≈ 0.768) emerge naturally and match Planck, DESI, and SH0ES observations. The model is falsifiable by Euclid (void profiles), LISA (PBH mergers), and CMB-S4 (tensor modes). Confirmed by full 3D Schrödinger-Poisson simulations yielding a central overdensity of ∼2.07 (Fig. 1b)
