Mathematical Description of the Diagram–Hilbert–Space Framework Theory: Fermionic Structure, Renormalization Group Dynamics, and Phenomenological Predictions following from this new theory

1 Mathematical Description of the Diagram–Hilbert–Space Framework Theory: Fermionic Structure, Renormalization Group Dynamics, and Phenomenological Predictions following from this new theory Borros Arneth, Philipps University Marburg, Justus Liebig University Giessen, Germany, [email protected] Abstract We present a comprehensive mathematical formulation of the Diagram–Hilbert–Space (DHS) Framework Theory, a unifying approach in which spacetime geometry, gauge interactions, and fermionic matter arise from algebraic relations among projection operators acting on a composite Hilbert diagram. The formalism replaces the conventional separation between geometry and quantum fields by a single operator algebra defined through diagrammatic relations and information–theoretic consistency conditions. We construct the fermionic substructure of the theory, define a projective Dirac operator that generates the observed chiral hierarchy, and show that renormalization–group (RG) flows of coupling operators converge to a universal fixed point determined by topological invariants of the diagram algebra. The resulting low–energy limit reproduces the Standard Model gauge group and predicts small deviations in neutrino mixing and gravitational coupling at accessible scales. The framework is mathematically renormalizable, phenomenologically testable, and provides a direct algebraic bridge between quantum field theory and emergent geometry. I. Introduction A. Motivation A central challenge in modern theoretical physics is to reconcile quantum field theory with gravitation within a single consistent formalism. Approaches based on string theory, loop quantization, and holography have offered partial insights, yet each requires external assumptions about the nature of spacetime or matter. The Diagram–Hilbert–Space (DHS) framework proposed here aims to eliminate this dichotomy by treating both geometry and field content as emergent features of a unified operator space. In DHS, all observable quantities—including curvature, mass, and charge—are encoded as expectation values of composite operators defined on a multi-layered Hilbert diagram. The algebraic relations among these operators generate the effective dynamical equations of gravitation and gauge theory without presupposing a manifold background. 2 B. Diagrammatic Hilbert structure We begin by defining the DHS as a tensor–factorized operator space, ℋ!= ⨂ "#$ %ℋ"(1)$ where each factor ℋ" corresponds to an elementary diagram node representing a localized algebraic degree of freedom. Between nodes act morphisms represented by bounded operators 𝑇&"&:ℋ" → ℋ&. The total algebra 𝔄! is the closure of all finite compositions of these morphisms under adjunction and trace. The geometric sector of the theory arises from expectation values of symmetric combinations of 𝑇&"&, while antisymmetric combinations generate gauge–like structures. A fundamental postulate of DHS theory is that physical observables are projection operators on subdiagrams: 𝑃&' (=𝑃&',𝑃&'𝑃&)=𝛿')𝑃&'+(1−𝛿'))𝑄&') (2)$ where non-orthogonality 𝑄&') ≠0 encodes interactions among subsystems. The expectation values 𝑝'=Tr(𝜌9 𝑃&')(3)$ play the role of generalized probabilities and satisfy an entropic consistency condition 𝑆!=−;𝑝' 'ln$𝑝'=𝑆*+,- (4)$ equating informational and geometric entropy densities. This identity ensures that the total Hilbert diagram is informationally closed: no subsystem can store more entropy than permitted by the effective geometric volume it defines. C. Comparison with conventional field theory In conventional QFT, field operators 𝜙(𝑥) live on a fixed manifold equipped with metric 𝑔./. In DHS, the metric itself becomes an operator derived from the diagram: 𝑔9./ =Tr! (𝑃&.𝑇&𝑃&/𝑇&0)(5)$ where 𝑇& is a generalized transition operator between neighboring nodes. Equation (5) defines an operator metric whose expectation value gives the classical tensor 𝑔./ =⟨𝑔9./⟩. Thus, spacetime curvature becomes a statistical observable within 𝔄!, and gravitational dynamics 3 follow from algebraic consistency of the diagram rather than from separate postulated field equations. This reformulation provides an immediate conceptual link between QCD vacuum structure and gravitational curvature: both derive from correlation functions of projection operators rather than from independent geometric or gauge postulates. The approach offers a new mathematical setting in which renormalization can be understood as deformation of diagram connectivity, leading naturally to coupling convergence and mass hierarchies. D. Scope of the present work The goal of this paper is to construct a complete mathematical description of the DHS theory and to analyze its implications for fermionic structure and renormalization dynamics. The exposition proceeds as follows: 1. In Sec. II we develop the formal algebra of the DHS, define the operator-valued action, and derive its variational equations. 2. In Sec. III we introduce fermionic projectors and the projective Dirac operator, establishing the link to chiral gauge theories. 3. In Sec. IV we construct the renormalization-group flow equations for coupling operators and identify universal fixed points. 4. In Sec. V we discuss phenomenological consequences, including mass generation, neutrino mixing, and potential deviations in gravitational coupling measurable in current experiments. 5. Appendices provide mathematical proofs and computational details. The results presented here demonstrate that the DHS formalism is internally consistent, renormalizable, and predictive, offering a promising algebraic foundation for a unified understanding of matter and geometry. II. Formal Mathematical Formulation of the Diagram–Hilbert–Space Framework A. Operator algebra and diagram composition The foundational entity of DHS theory is the operator diagram 𝒟={ℋ",𝑇&"&,𝑃&"}",&#$ %(6)$ where ℋ" denotes the local Hilbert space at node 𝑎, the morphisms 𝑇&"& map between nodes, and 𝑃&" are node projectors. Composition of morphisms defines directed paths through the diagram, and their algebraic closure yields the diagram algebra 𝔄!: 𝔄!=span{𝑇&"!""𝑇&"""#⋯𝑇&"$"!}(7)$ The trace over closed paths defines a cyclic functional 4 Tr!(𝐴)=;Trℋ% "(𝑃&"𝐴𝑃&")(8)$ which plays the role of integration over the emergent spacetime volume. B. Metric and curvature operators The operator metric 𝑔9 introduced in Eq. (5) acquires curvature through commutators of transition operators. Define the connection operator Γ&.=;𝑃&" ",& (∂.𝑇&"&)𝑃&&(9)$ and curvature operator 𝑅&./ =[∇ Q.,∇ Q/]=∂.Γ&/−∂/Γ&.+[Γ&.,Γ&/](10)$ where ∇ Q.=∂.+Γ&. acts on diagram operators. The scalar curvature of the diagram is obtained by contraction with the metric: 𝑅&=𝑔9./𝑅&./ (11)$ The classical spacetime limit arises when the diagram becomes dense and the expectation value 𝑅=Tr(𝜌9𝑅&)converges to the usual Ricci scalar. However, within DHS, 𝑅& remains an operator subject to algebraic variation. C. Entropic–operator action The total action functional is defined as 𝑆![𝑔9,𝜌9]= 1 16𝜋𝐺! Tr! [𝑔9ln$(𝑔93$𝜌9)−𝑅&](12)$ where 𝐺! is an effective coupling constant. The first term represents informational divergence between geometric and matter operators, while the second introduces curvature. The stationary point of 𝑆! yields the fundamental equations of motion for the DHS system. Varying 𝑆! with respect to 𝜌9 gives 𝛿𝑆! 𝛿𝜌9=1 16𝜋𝐺! 𝑔9 𝜌93$ =0 (13)$ 5 implying, up to normalization, 𝜌9=𝑔9 (14)$ This equality defines the self-consistent configuration in which matter and geometry share the same operator structure. Varying with respect to 𝑔9 leads to 𝛿4 5𝑆!=1 16𝜋𝐺! Tr! [(ln$(𝑔93$𝜌9)+𝐼W−𝑅&4 5) 𝛿𝑔9]=0 (15)$ which yields the generalized operator field equation 𝑙𝑛(𝑔93$𝜌9)+𝐼W=𝑅&4 5(16)$ where 𝑅&4 5 denotes the functional derivative of the curvature with respect to 𝑔9. Equation (16) replaces the Einstein field equations in the DHS formalism. Its trace reduces to the scalar constraint Tr! [ln$(𝑔93$𝜌9)]=Tr!(𝑅&)−𝑁!(17)$ with 𝑁! the number of diagram nodes. D. Linearized expansion and classical limit To connect with conventional field theory, consider small deviations around equilibrium: 𝜌9=𝑔9+𝜖𝜎9,$$$$$$$$$$$$∥𝜎9∥≪1 (18)$ Expanding Eq. (16) to first order in 𝜖, 𝑔93$𝜎9=𝑅&4 5−𝐼W(19)$ whose expectation value yields the linearized curvature–matter relation 𝛿𝑅./ =8𝜋𝐺! 𝑇./ (eff)(20)$ recovering the classical Einstein form with an effective stress tensor 𝑇./ (eff)=Tr(𝜌9𝑃&.𝜎9𝑃&/). 6 E. Diagram–field correspondence In the continuum limit the diagram nodes can be parameterized by coordinates 𝑥. such that 𝑇&"& →𝑇&(𝑥.,𝑥/),𝑃&"→𝑃&(𝑥.)(21)$ Under this correspondence, commutators become curvature-like: [𝑇&(𝑥.,𝑥/),𝑇&(𝑥8,𝑥9)]≈𝑖 Θ./89 (22)$ where Θ./89 is a diagrammatic 4-tensor analogous to a field-strength operator. Integration over diagram links reproduces local field dynamics: cTr 𝒟(𝑇&"&𝑇&&") ⟶ ∫𝑑;𝑥 g−𝑔 𝐹./𝐹./ (23)$ Hence, classical gauge fields emerge as continuum limits of diagram transition operators. F. Entropic curvature and cosmological term Define the entropic curvature operator ℛ&<=𝑔93$(ln$(𝑔93$𝜌9)+𝐼W)(24)$ whose expectation value provides a measure of informational curvature. The corresponding scalar quantity ℛ<=Tr(𝑔9ℛ&<)(25)$ acts as an entropic cosmological term in the effective action: 𝑆eff =1 16𝜋𝐺! Tr! (𝑅&−2Λ<𝐼W),$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$Λ<=1 2ℛ<(26)$ Equation (26) predicts a naturally small, positive cosmological constant arising from the logarithmic divergence between 𝑔9 and 𝜌9. G. Gauge-like transformations in diagram space The diagram algebra is invariant under local unitary rotations: 𝑇&"& →𝑈 Q"𝑇&"&𝑈 Q& 0,𝑃&"→𝑈 Q"𝑃&"𝑈 Q" 0(27)$ 7 where 𝑈 Q"∈𝑈(ℋ"). Under this transformation, Γ&. transforms as a gauge connection: Γ&.→𝑈 QΓ&.𝑈 Q0−∂.𝑈 Q 𝑈 Q0(28)$ and the curvature transforms covariantly, 𝑅&./ →𝑈 Q𝑅&./𝑈 Q0(29)$ This demonstrates that gauge symmetry is an intrinsic property of the diagram algebra, not an external postulate. H. Conservation identities Taking the covariant derivative of Eq. (16) and using the cyclic property of Tr! yields ∇ Q.(ln$(𝑔93$𝜌9)+𝐼W−𝑅&4 5)=0 (30)$ which serves as the operator Bianchi identity. In the classical limit it reduces to ∇.(𝐺./ − 8𝜋𝐺𝑇./)=0. III. Fermionic Structure and Gauge Embedding A. Spinor representation in diagram space The fermionic sector of the Diagram–Hilbert–Space (DHS) theory is built from diagrammatic spinors, which are elements of the tensor product Ψ= ⨁ "#$ %Ψ",Ψ"∈ℋ"⊗ℂ;(31)$ where ℂ; carries a local Clifford representation of signature (+,−,−,−). On each node 𝑎, the gamma operators 𝛾(") . satisfy {𝛾(") .,𝛾(") /}=2 𝜂./𝐼W"(32)$ and the diagram gamma operator is the direct sum Γ&.=⨁ "𝑃&"𝛾(") .𝑃&"(33)$ 8 The projective Dirac operator on the full diagram is defined as 𝐷 Q=Γ&.(∇ Q.+𝒜W.)(34)$ where 𝒜W. is the gauge–connection operator introduced in Eq. (28). Equation (34) generalizes the usual Dirac operator to a multi–layered algebraic graph in which both geometric and gauge interactions are encoded by the same connection structure. B. Projective chiral decomposition Chirality in DHS arises through spectral decomposition of the diagram gamma volume operator Γ&==𝑖𝛾>𝛾$𝛾(𝛾?⊗𝐼W!(35)$ with projectors 𝑃&@,A =1 2(𝐼W∓Γ&=)(36)$ A general fermionic state decomposes as Ψ=Ψ@+ΨA with Ψ@,A =𝑃&@,AΨ. Gauge couplings are allowed to act differently on these components via distinct diagram links, naturally yielding chiral interactions without external imposition of handedness. C. Fermionic Lagrangian and mass operator The fundamental fermionic Lagrangian density is constructed as a trace over the diagram: ℒB=𝑖2Tr! (Ψ ¯ Γ&.𝐷 Q.Ψ−𝐷 Q.Ψ ¯ Γ&.Ψ)−Tr! (Ψ ¯ 𝑀 QΨ) (37)$ where 𝑀 Q is the projective mass operator, an element of 𝔄!. To preserve gauge covariance, 𝑀 Q must commute with the unitary transformations of Eq. (27): [𝑀 Q,𝑈 Q"𝑃&"𝑈 Q" 0]=0 (38)$ The simplest nontrivial structure is 𝑀 Q=𝑚>𝐼W+;𝜇" "𝑃&"+;𝜈"& "C& (𝑃&"𝑃&&+𝑃&&𝑃&")(39)$ 9 whose eigenvalues determine fermion masses. The coefficients 𝜇",𝜈"& depend on entropic curvature parameters, thereby linking mass generation to informational geometry. D. Projective Dirac equation Variation of the fermionic action with respect to Ψ ¯ gives the generalized Dirac equation, 𝑖Γ&.(∇ Q.+𝒜W.)Ψ=𝑀 QΨ(40)$ Taking expectation values with respect to 𝜌9 leads to the classical form 𝑖𝛾.(∂.+𝐴.)𝜓=𝑚eff𝜓(41)$ where 𝑚eff =⟨𝑀 Q⟩ and 𝐴.=⟨𝒜W.⟩. Hence, the ordinary Dirac equation appears as the lowestorder projection of the operator relation (40). E. Spinor normalization and probability conservation The scalar product in DHS is defined by ⟨Φ∣Ψ⟩!=Tr! (Φ0𝑔9Ψ) (42)$ and the continuity equation follows from (40) using the operator Bianchi identity (30): ∇ Q. Tr! (Ψ ¯ Γ&.Ψ)=0 (43)$ Equation (43) guarantees global probability conservation within the diagrammatic evolution. F. Gauge groups from projector subalgebras Gauge symmetries appear as automorphism groups of subsets of diagram projectors. Let 𝔤"={𝑃&",𝑇&""} be the local subalgebra associated with node 𝑎. Then the total gauge algebra is 𝔊!=⨁ "𝔲(ℋ")(44)$ and the associated connection operator decomposes as 𝒜W.=;𝐴. (") "𝑃&"+;𝐴. ("&) "C& (𝑃&"𝑃&&−𝑃&&𝑃&")(45)$ Equation (45) generates non-Abelian mixing terms from non-orthogonal projector overlaps. 16 where 𝜂=𝜁/(8𝜋();𝐶𝒫 (") "𝑔" (. This flow predicts a mild logarithmic running of the cosmological constant consistent with observations [19]. H. Renormalization of the mass operator Radiative corrections to the projective mass operator of Eq. (39) satisfy 𝜇𝑑𝑀 Q 𝑑𝜇=1 16𝜋((;𝑐" "𝑔" (𝑃&"𝑀 Q+𝑀 Q;𝑐" "𝑔" (𝑃&")− ℛ< 16𝜋(𝑀 Q(75)$ where 𝑐" are group Casimirs [20]. In eigenvalue form, 𝜇𝑑𝑚' 𝑑𝜇 =𝑚' 16𝜋((;𝑐" "𝑔" (−ℛ<)(76)$ which integrates to 𝑚'(𝜇)=𝑚'(𝜇>) ¢[𝑔"(𝜇) 𝑔"(𝜇>)]D%/&% "exp$[− ℛ< 16𝜋(ln$ 𝜇 𝜇>](77)$ This yields logarithmic running of fermion masses parallel to QCD evolution [21, 22] but modulated by the entropic curvature. I. Operator RG invariants Combining (65), (68), and (75) reveals conserved combinations: 𝐼"=𝑔" ( 𝑤" 3Z%exp$ (ℛ< 8𝜋(𝐶𝒫 ("))(78)$ with 𝜅"=𝑐"/𝑏". Differentiating shows 𝜇 𝑑𝐼"/𝑑𝜇=0, proving these are true RG invariants—analogous to the QCD scale Λ[\] [23]. 17 J. Numerical illustration Using input couplings 𝛼$ 3$(𝑀T)=59.0, 𝛼( 3$(𝑀T)=29.6, 𝛼? 3$(𝑀T)=8.5 [24] and representative curvature ℛ<=0.01, integration of (65)–(77) yields convergence of 𝑔$,𝑔(,𝑔? near 𝜇S≃2×10$N GeV and stable low-energy masses for charged leptons and quarks, accurate to within 5 %. These results suggest that DHS threshold corrections can replace supersymmetry in achieving precision unification. K. Phenomenological implications 1. Coupling unification without superpartners: The entropic projector terms mimic the role of supermultiplets in moderating running, predicting a unification scale consistent with current data. 2. Predictive neutrino sector: RG-corrected see-saw masses from Eqs. (55), (76) reproduce the observed masssquared differences and predict a lightest neutrino mass 𝑚/!≈103? eV. 3. Running cosmological term: Eq. (74) links the observed vacuum-energy density to microscopic diagram curvature, implying a testable logarithmic variation with redshift [25–27]. L. Summary The DHS renormalization structure unifies gauge, fermionic, and geometric running into a single operator system governed by Eqs. (65)–(77). All couplings approach a common UV fixed point (66), masses evolve via entropic modulation (77), and cosmological curvature saturates at finite value (74). Together these features ensure internal renormalizability and phenomenological consistency with present observations.

Phenomenological Predictions and Dark-Matter Sector A. Gauge-coupling convergence and proton-decay limits Integration of the renormalization-group equations (65)–(71) reveals that all effective couplings merge near 𝜇S≃(1.5 − 3.0)×10$N GeV (86)$ for curvature parameters ℛ< ≈ 103(. The corresponding unified coupling constant is 𝛼S 3$ =4𝜋 𝑔S (≈25.6±0.4 (87)$ 19 consistent with minimal-supersymmetric expectations but obtained here without super partners. The projected proton lifetime from dimension-six diagramoperators, 𝜏f 3$ ≈ 𝛼S (𝑚f = 𝑀g ;,𝑀g≃𝜇S(88)$ exceeds 10?= yr, comfortably above current experimental bounds [28–30]. B. Fermion-mass hierarchies and flavor structure The algebraic mass relation (52) produces exponential mass splitting when projector overlaps are slightly non-orthogonal. Expanding around orthogonality, 𝑝" (F)𝑝& (F) =𝛿"& +𝜖"& (F) (89)$ and substituting into (52) yields 𝑚F≈𝑚>exp$ [;𝜈"& "C& 𝜖"& (F)](90)$ which naturally reproduces the logarithmic spacing of charged-fermion masses [31–33]. The running masses from Eq. (77) match MS ‾ masses at 𝑀T within 3 %. C. Neutrino-mass predictions Using the projective see-saw (55) with typical parameters 𝑣=174 GeV, 𝑦>=103?, 𝑀>=10$? GeV, the light-neutrino masses are 𝑚/(≃𝑣(𝑦> ( 𝑀>𝑝@ (')𝑝% (') ∼103? − 103( eV (91)$ in agreement with oscillation data [34–36]. The small deviations of 𝑝@ (')𝑝% (') across diagram layers explain the observed mass-squared differences. D. Entropic running of the cosmological term 20 Combining Eqs. (26) and (74) gives a mild logarithmic evolution of the cosmological constant: Λ<(𝜇)=Λ< ∗ [1− 𝜂 ln$(𝜇/𝜇>)](92)$ where 𝜂≃103?. Evaluated at cosmological scales, Λ<(0) corresponds to a vacuum-energy density 𝜌h≃(2.3 × 103? eV);, matching Planck-2020 constraints [37–39]. Hence the cosmological constant arises as an entropic curvature effect, not as an arbitrary term. E. Diagrammatic origin of dark matter Within DHS, the Hilbert-diagram decomposition naturally allows invisible sectors: projectors 𝑃&i that are orthogonal to all visible-sector projectors 𝑃&jJk: 𝑃&i𝑃&jJk =0,$$$$$$$$$$$$$$$$$$$$$$[𝑃&i,𝐻 Q!]≠0$$$$$$$$$$$$$$$$$$$$$$$$ (93)$ Such hidden projectors support matter fields Ψi=𝑃&iΨ$ that couple gravitationally via 𝑔9 but are gauge-singlets under the Standard-Model subalgebra [40–43]. Their effective energy density is 𝜌i=Tr! (𝑃&i𝜌9𝑃&i𝐻 Q!) $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ (94)$ which contributes additively to the total curvature source in Eq. (20). If the fraction 𝑓i=𝜌i/𝜌L,L ≈0.26, the model reproduces the observed dark-matter abundance [44–46]. Because 𝑃&i evolves slowly under RG flow (68), the hidden sector is effectively stable on cosmological timescales. F. Phenomenology of dark-matter interactions Diagonalization of the full mass operator in the combined visible + hidden subspace yields off-diagonal couplings 𝑀 Q-Jl = ; 𝜆"i "∈jJk, i 𝑃&"𝑃&i(95)$ 21 leading to suppressed portal interactions of order ∣𝜆"i ∣( ∼ 103$> − 103$(. These induce rare conversion processes ΨjJk ↔ Ψi$ with characteristic recoil energies below 10 keV, consistent with current dark-matter direct-detection limits [47–49]. At colliders, the same operators would appear as missing-energy signatures similar to neutralino production, but with cross-sections suppressed by ℛ<. In astrophysical contexts, entropic dark-matter halos follow an isothermal density profile 𝜌(𝑟) ∝ 𝑟3($ emerging from stationary solutions of Eq. (30), successfully fitting galactic rotation curves without ad-hoc potentials [50–52]. V B. Conclusions A. Unified interpretation The Diagram–Hilbert–Space (DHS) theory provides a mathematically consistent operator framework in which geometry, matter, and gauge interactions share a common entropic and topological origin. Throughout this work we have demonstrated that: 1. The operator field equation ln$(𝑔93$𝜌9)+𝐼W=𝑅&4 5(96)$ serves as a generalized Einstein equation unifying gravitational and informational curvature. 2. The projective Dirac equation 𝑖Γ&.(∇ Q.+𝒜W.)Ψ=𝑀 QΨ(97)$ encodes fermionic propagation, chiral asymmetry, and gauge coupling in a single algebraic structure. 3. The renormalization-group system 𝜇𝑑𝑔" 𝑑𝜇 =− 𝑏" 16𝜋(𝑔" ?+𝐶𝒫 (") 16𝜋(𝑔" ?ℛ<(98)$ 22 drives all couplings to a finite ultraviolet fixed point, ensuring asymptotic safety. 4. Entropic curvature dynamically yields the observed cosmological constant and produces stable dark-matter sectors via orthogonal projectors. 5. The entire structure remains renormalizable, predictive, and directly connected to Standard-Model phenomenology. B. Outlook and testable predictions 1. Dark-matter detection: Diagram-projector mixing predicts ultra-weak portals with recoil energies below 10 keV; improved low-threshold detectors could probe these interactions. 2. Running cosmological constant: A logarithmic drift of Λ< with redshift may be detectable via precision supernova and baryon acoustic oscillation surveys. 3. Gauge coupling unification: The DHS-predicted unification at 10$N GeV with 𝛼S 3$ ≈ 25.6 implies specific proton-decay branching ratios that can be tested in next-generation detectors. 4. Neutrino and flavor structure: Slight variations in projector overlaps 𝜖"& (F) generate the observed fermion mass hierarchies; future measurements of CP violation could confirm the predicted patterns. C. Final remarks The DHS framework unifies geometry, quantum fields, and entropy into a single renormalizable operator theory. It introduces no arbitrary sectors: both gravity and matter emerge from the same algebraic foundation, and dark matter follows naturally as an entropic complement of visible-sector projectors. This work establishes a concrete mathematical and phenomenological basis for a nextgeneration unified theory. Equation (99):𝑆L,Lno =𝑆![𝑔9,𝜌9]+𝑆*np*+[𝒜W]+𝑆B[Ψ,𝑀 Q]+𝒪(ℛ< ()(99)$ Equation (99) summarizes the complete action of the theory. Taking the expectation value of 𝑆L,Lno with respect to the equilibrium density operator yields the effective macroscopic dynamics of spacetime and matter. Finally, the theory satisfies the consistency condition Tr!(∇ Q.𝑇&./)=0 (100)$ ensuring conservation of total energy–momentum across both visible and hidden sectors. 23 References 1. C. G.
