This comment examines the mathematical framework developed by Bryan Sanctuary across a series of papers and preprints (2023–2025) concerning bivector and quaternion representations of spin and claims regarding Bell correlations. We focus on the internal algebraic structure, the treatment of measurement correlations, and the use of linear combinations of projections from a single global bivector. We find that the framework is internally consistent, preserves positivity of expectation values, and produces correlations resembling the quantum correlation −a·b. These correlations are generated using a shared global algebraic object rather than from ±1-valued random variables satisfying the locality and factorization hypotheses of Bell’s non-existence theorem. Consequently, the results are best understood as describing a non-trivial classical geometric framework that lies outside the scope of Bell’s theorem, rather than as a contradiction of it. The analysis is restricted to mathematical and probabilistic considerations, without reference to physical or experimental interpretations.

We examine the logical and mathematical structure of Sanctuary's recent paper (\emph{Quantum Rep.}\ 2026, 8, 96), which argues that spin observables in the Bivector Standard Model (BiSM) are not jointly definable on a single Kolmogorov probability space, so that the CHSH quadruple cannot be formed and Bell's and Fine's theorems do not apply. The paper contains two constructions: local response functions of the analyser setting and a shared source phase, and a separate prescription that produces the correlation −cos(a−b). We show that the first construction, as specified, meets the hypotheses of Bell's theorem. Its outcome maps are defined on a common source domain with a setting-independent distribution, so the non-existence claim (Lemma~3, Corollary~3) does not hold for it, its product correlations obey the CHSH bound, and the paper's own simulation of it yields the Bell triangle. The cosine is obtained instead from a scalar computed jointly from both stations' phases and then digitised; it is not shown to be the correlation of the local outcomes. Execution of the supplementary programs further shows that the four BiSM\_v2 populations do not form the partition stated in the paper, and that the doubled-angle harmonic attributed to the raw coherence data appears only after a sign convention is applied on the second half-cycle.
Bell’s theorem is a foundational result in quantum theory, demonstrating that no local hidden-variable model satisfying certain assumptions can reproduce quantum correlations. While mathematically correct within its formal framework, the theorem implicitly relies on a specific representational choice: measurement outcomes are modeled as scalar, commutative variables (±1). This assumption, though natural for flat and static configurations, is not mandated by physical necessity. In this work, we examine the consequences of relaxing this representational constraint when measurement outcomes arise as projections of states with nontrivial topology. We show that when physical correlations are naturally organized as elements of an S³-valued structure — such as those associated with spin and rotational degrees of freedom — the induced measurement algebra becomes noncommutative. Under these conditions, the key algebraic factorizations employed in Bell-type derivations no longer apply. We construct an explicit local, realistic model in which observable correlations reproduce the quantum expectation E(a, b) = − cos θ and violate the CHSH bound S ≤ 2, without invoking non-local interactions or superluminal influences. The effective S³×I structure arises not as a fundamental substrate, but as the natural geometric form taken by the actualization of physical processes within an underlying relational framework. Importantly, this structure was not introduced to address quantum entanglement specifically; it emerged independently in the study of cosmological expansion, emergent gravity, and mass generation. Its relevance to Bell-type correlations follows as a consequence of geometry, not as an ad hoc modification. These results suggest that quantum entanglement may reflect topological features of physical realization rather than intrinsic non-locality.

Abstract A statistical simulation is presented which reproduces the correlation obtained from EPR coincidence experiments without non-local connectivity. We suggest that spin carries two complementary properties. In addition to the spin polarization, we identify spin coherence. This spin attribute is anti-symmetric and generates the helicity. In addition this spin has structure formed from two orthogonal magnetic moments. From these, a resonance spin results from their coupling in free flight. Upon encountering a filter, the resonance spin 1 decouples back into two independent spins of ½, with one aligning with the filter and the other randomizing. The process of decoupling the resonance spin is responsible for the quantum correlation which results in the observe violation of Bell's Inequalities. The polarized states give a CHSH value of 2 while the resonance spin give a CHSH value of 1. Coherence can only be formulated by the existence of a bivector which gives a spin the same geometric structure as a photon. Although this work is not about Bell's theorem, we note that there are no hidden variables (HV). The only local variable is the angle that orients a spin on the Bloch sphere, first identified in the 1920's. The new features introduced are changing the spin symmetry from SU(2) to the quaternion group, Q8, and the introduction of a bivector into spin which leads to an element of reality which is anti-Hermitian. The calculations use standard spin algebra, and properties of quaternions. March 28, 2023
We revisit the Bell--CHSH scenario for two spin-21 particles and isolate the precise algebraic origin of the Bell contradiction. On the quantum side, spin-21 is described by a noncommutative spinor (Clifford) algebra acting on the Hilbert space of two spin-21 particles, with the singlet state yielding the usual correlation E(a,b)=−a⋅b and Tsirelson's bound 22. On the classical side, the standard Bell assumptions amount to describing all measurement outcomes as {±1}-valued random variables on a single Kolmogorov probability space, i.e.\ elements of a commutative algebra C(Λ).
We show that there is no representation of the spinor algebra of spin-21 (with its singlet state and locality structure) into any such commutative Kolmogorov algebra that preserves the {±1} spectra of local spin components and the singlet correlations entering the CHSH expression, under the standard Bell assumptions of locality (factorization) and measurement independence. In this sense, the Bell--CHSH contradiction is exhibited as an algebraic mismatch between a noncommutative spinor/Clifford description of spin and the classical assumption of a single global Kolmogorov space supporting all outcomes. In the language of quantum probability, this is a C∗-algebraic reformulation of the known fact that the singlet correlations admit no local hidden-variable model with jointly distributed outcomes on one probability space.
We also give an explicit realization of the same spinor structure within the author's Quantum Index Algebra (QIA) framework, where locality appears as disjoint index slots and the singlet state as a simple index cocycle.
Bell’s theorem is widely understood as demonstrating that quantum correlations cannot be explained by any theory of local hidden variables. The experimental violation of Bell inequalities has therefore often been interpreted as evidence for nonlocality or “spooky action at a distance.” This paper proposes a different geometric interpretation. It accepts Bell’s theorem as a decisive refutation of separable preassigned vector realism, but argues that entangled systems need not be modeled as pairs of particles carrying hidden local vector outcomes. Instead, the entangled state is interpreted as a nonseparable bivector coherence relation whose correlated vector outcomes are disclosed only through measurement. On this view, measurement is a basis-conditioned reduction from bivector structure to local vector registration. The standard singlet correlation E(a,b)=-a⋅b, including the Tsirelson bound S=2√2, is then interpreted as the scalar trace of a shared bivector relation rather than as the result of superluminal influence. The framework does not deny Bell’s theorem, Bell experiments, or quantum statistics. It instead reframes their ontological meaning: Bell violation marks the failure of separable vector completion, not the necessity of action at a distance.
