One-Octonion Brane-Bulk Framework — Paper CCCIV: The Fifth-Force Desert — Brane-Bulk Forbids Every Yukawa Deviation from Newtonian Gravity, Where UV-Complete Scalar-Tensor Gravity Forbids Only the Short-Range Ones

Bonanno the third lies far to the RIGHT and produces a shear-thinning a0/MOND modification, not an exponential Yukawa. The framework thus has an exact mass gap straddling the entire torsion-balance window, predicting alphaY < ~1e-59 everywhere (a fifth-force desert). The two programmes AGREE there is no short-range Yukawa (asymptotic safety because the RG flow forbids it; OOB because no light scalar exists) but DIVERGE on the long-range sector, where asymptotic safety permits a Yukawa wedge and OOB permits only the non-Yukawa a0 modification. This yields a two-way discriminator: a detection of any exponential Yukawa fifth force at any range falsifies OOB; a confirmation that the long-range/low-acceleration modification is a0/MOND-shaped disfavours the asymptotic-safety light-scalar picture. The Bonanno-Glaviano UV-completion boundary is reproduced by direct pixel-digitization of their Fig. 2 (log10 alphaY = 3. 63 log10 lambdaY - 24. 94) ; their verbatim figure is NOT reproduced (copyright APS). Honest status: the OOB prediction is one of absence, asserted from the discrete-lattice / generalized-uncertainty cutoff and the explicit scalar inventory, not from a dynamically-derived mass gap; meeting asymptotic safety on its own ground requires deriving the gap from a flow. Zero new free parameters (uses mP, mH, hbar H0, fbulk only). Verification script bundled, 17/17 PASS.
