One-Octonion Brane-Bulk Framework, Paper CCCXLVIII. The first global extraction of the genuine twist-three (quark-gluon-quark interference) distributions (Vladimirov, Portela & Rodini, PRL 137, 061902 (2026); companion arXiv:2607.01866) finds interference terms comparable in size to the parton densities, and average transverse colour forces on the u and d quarks that are - in the authors' words - "almost equal to each other and opposite in the sign." This paper accounts for both from the framework's ontology: the proton's interior is not a beam of independent partons but one coherent standing wave of brane current, anchored at three quark focal zones whose colour windings sum to zero (Paper LXVII). Two balance laws follow. (i) A stationary standing wave exchanges no net transverse momentum with its own content, so the framework requires the Burkardt sum rule Σf ⟨k⊥⟩f = 0 exactly - where QCD obtains it within the parton model and the companion states it "generally could not hold in QCD". (ii) Every winding terminates on an anchor, so the spin-correlated asymmetry budget closes within the three valence anchors alone - valence saturation - forcing fd = −2fu per anchor and an equal-and-opposite flavour-total cancellation. The sign flip is a majority/minority anchor effect, not an electric-charge effect; no step uses charge. Method, stated up front. This is not a re-derivation of QCD results through QCD machinery and is not offered as one. The framework embeds SU(3) ⊂ G2; it does not rival quantum chromodynamics but accounts for the same phenomena by a different route. No operator-level dictionary between focal zones and twist-three correlators is supplied - that is named as the paper's principal open item. What is offered is a prediction about the measured quantities, and in one case a prediction that differs from the QCD expectation in a way precision can decide. Confrontation. The flavour-total force sum vanishes at 0.06-0.39σ across all quoted scales and the valence ⟨kx⟩ sum at 0.03-0.73σ. A direct evaluation of the authors' public 300-replica SnowART26 ensemble, with full correlations, gives force ratio −0.91 (+0.24/−0.47) against the predicted −1 and normalised sum +0.09 (+0.24/−0.48) against 0 - both 0.25σ on the symmetrised convention. Validation: the central replica reproduces companion Table 7 (ku = +7.95 vs their +7.9; all eight flavour signs correct). Registered predictions. P-CCCXLVIII-1 (valence saturation) - the gluon and sea contributions vanish separately; this is the framework's distinct, non-degenerate content, which large-Nc does not predict. Sharpened with an independent falsification criterion: the fitted gluon Qiu-Sterman moment (−42.8 ± 18 MeV in the present posterior) is held to be an artefact of the one-parameter gluon ansatz; an extraction that (a) includes an observable with direct gluon sensitivity, (b) reports the moment with a data-dominated uncertainty below 15 MeV, and (c) finds it more than 3σ from zero kills P-CCCXLVIII-1. P-CCCXLVIII-2 - the cancellation holds beyond the ~30% level where 1/Nc corrections sit (EIC-era). P-CCCXLVIII-3 - exact q/q̄ force cancellation pair-by-pair for mesons. Honest scope, stated in the paper. The extraction is a first detection at 2-3σ with a multi-parameter ansatz; the sub-σ agreements reflect large uncertainties and cannot by themselves establish exactness. The flavour-total cancellation is numerically degenerate with the known large-Nc expectation. The absolute orientation (one binary chirality datum) and the magnitude (|⟨f⟩| ≈ 80 MeV/fm) are not derived. The gluon tension is the paper's weakest point and is treated as a bet, not argued away. Verification: verify_transverse_force_balance_2026_08_11.py (12/12); replica-ensemble computation over 300 replicas, all regular; cross-model fugu fidelity and kill-argument rounds with surviving items repaired.
