In the Absolute Frame Theory (AFT) the Higgs is not a fundamental field: it is the chiral anisotropy of the background embedding X₀ of the observable four-dimensional manifold M into a flat ten-dimensional Euclidean substratum A, the neutral component of the electroweak bidoublet (1, 2, 2) identified with the 4 of the tangent Spin (4) sub-bundle. We compute its effective potential, self-couplings, and unitarity, sorting every statement into what AFT derives and what it does not. The routing term of the AFT action evaluated on a single-plane-wave pilot wave---a theorem under substratum homogeneity---produces a bounded cosine potential V () =-g_ (₀+kₙ). Because the embedding field space is flat Cartesian R⁴, the kinetic and gauge sector is Standard-Model-like, V=1, in contrast with composite-Higgs constructions on a curved coset, where V=1-. The self-couplings follow from the cosine: the trilinear vanishes, _=0---a robust prediction, the only source able to switch it on being local spacetime curvature, suppressed by a factor 10^-59 in canonical normalization with the embedding tension T₀ cancelling---while the quartic is negative, ₄=-/3, with a 20\% renormalization-group shift to the scale f. The resulting signature (V, _, ₄) (1, 0, -/3) is a point inaccessible to genuine composite Higgs models, which correlate V and _ through a single parameter. Tree-level perturbative unitarity is sound to the natural cutoff s f=v/, and one-loop vacuum stability is better than the Standard Model, a bounded cosine replacing a metastable quartic. The relation mₕ²=g_/f² is dimensionally consistent. The prediction _=0 is testable at the high-luminosity LHC; the standard V-driven compositeness bound is evaded because V=1, leaving largely unconstrained. AFT derives the form and the correlations among these couplings; the electroweak scale v, the phase ₀, , the amplitude g_, and the gauge-coupling values remain boundary data of A.
