Relational Actualism I introduces a discrete framework for fundamental physics in which spacetime is modeled as a finite causal graph evolving through irreversible event formation. Building on causal set theory, the framework defines a sequential growth process governed by the Benincasa–Dowker–Glaser (BDG) action and a local conservation law, the Local Ledger Condition. Unlike standard formulations of quantum theory and relativity, the theory treats actualization itself as primitive and does not assume a continuum spacetime, wavefunction, or collapse rule. The paper establishes the core kernel of the theory—its axioms, growth rule, acceptance criterion, and active support surface—and identifies open targets including quantum-statistical frequency laws, covariance closure, and macroscopic spacetime structure.

Relational Actualism (RA) is a foundational framework in which on-shell actualization events — irreversible physical interactions satisfying ΔS(ρ‖σ₀) > 0 that write permanent vertices into a growing causal Directed Acyclic Graph — are taken as the primitive constituents of physical reality. From this single ontological commitment, with no new fields or free parameters, the framework derives the results of Papers 1–3 and unifies quantum mechanics, general relativity, and emergent complexity under one algorithm. The Engine of Becoming is a five-step Covariant Stochastic Graph Rewriting System. Step 1 identifies the causal frontier ∂G. Step 2 assigns quantum amplitudes to all possible extensions via Sorkin's foliation-independent quantum measure. Step 3 filters candidates by the entropy criterion ΔS > 0 — a Lorentz scalar, formally verified as frame-independent in Lean 4. Step 4 selects actualizing events with probability given by the quantum measure, yielding the Born rule without postulate. Step 5 recomputes the effective metric from the actualization density λ(x) via Gᵤᵥ = 8πG(Tᵤᵥ^(A) + Θᵤᵥ^(λ)), where Θᵤᵥ^(λ) = ξ[∇ᵤ∇ᵥ(ln λ) − gᵤᵥ□(ln λ)]. Quantum mechanics is the Level-2 (slowly varying λ) limit. General relativity is the Level-3 (dense graph) limit. The Einstein equations with Λ = 0 are the unique macroscopic output, established by the Local Ledger Condition (Lean-verified), the BDG action as the unique discrete Lorentz-invariant action in d = 4 (Glaser 2014), and Lovelock's uniqueness theorem. Time in RA is not a background parameter. Time is the process of the causal DAG growing. Proper time along a worldline is the count of actualization events τ = N_act/λ₀. The arrow of time is not derived from entropy gradients: it is encoded in the directed edges of the DAG, which are irreversible by construction. Ontic randomness at Step 4 is irreducible: the outcome of an actualization event is not determined by any prior fact in V. This is not epistemic uncertainty but the universe's genuine openness. The framework generates an emergent complexity hierarchy through iterated Step-5 coarse-graining. Biological assembly corresponds directly to actualization events (each JOIN operation in Assembly Theory is an exothermic on-shell energy transfer, confirmed by B3LYP/6-311+G* DFT across all five primary biological bond types). The Causal Firewall is the μ = 1 Erdős-Rényi percolation transition: the same critical actualization density governs QCD confinement–deconfinement, flat galactic rotation curves, fault-tolerance thresholds in quantum error correction, and the onset of stable biological complexity. Biosignatures should correlate with thermodynamic environments sustaining μ ≥ 1. The complete falsifiable prediction set of the program comprises 18 specific predictions spanning particle physics, quantum optics, cosmology, quantum computing, and astrobiology, all tabulated here. Hard walls are stated with precision: Bianchi compatibility, amplitude locality (discrete intrinsic proof), continuum limit convergence, and the covariant □(ln λ) extension. Collaboration targets are identified for each.
The incompatibility of quantum mechanics and general relativity arises from ashared foundational error: both frameworks treat time as a background parameterrather than a physical process. Relational Actualism (RA) dissolves this tensionby replacing both the Schr\"odinger equation and the Einstein field equationswith a single **Covariant Stochastic Graph Rewriting System**—the Engineof Becoming. The algorithm operates on the growing causal Directed Acyclic Graph(DAG) of actualization events at three levels: (1) a graph-theoretic primitivelayer describing candidate extensions of the causal boundary; (2) a quantummeasure layer assigning complex amplitudes to causal histories in afoliation-independent way, using Sorkin's quantum measure formalism; and (3) anemergent layer in which the Feynman path integral and the Einstein field equationsare the macroscopic descriptions: the quantum measure is exact at Level 2 andthe Feynman integral is its large-μ approximation; the Einstein fieldequations are the unique consistent Level 3 description, proved in the companionpaper RACL via Lovelock's theorem,the Lean-verified LLC, and the Pacₜ conservation theorem. The foliation-independence of the quantum measure(causal invariance) is the RA statement of Lorentz covariance at the discretelevel, and its combinatorial core has now been formally verified in the Lean 4theorem prover. Furthermore, by defining actualization via an irreversibleincrease in quantum relative entropy and leveraging the Continuous FunctionalCalculus, we prove the Stationarity Criterion for the Rindler thermal state,resolving the Unruh paradox without breaking Lorentz covariance. The algorithmmakes a specific, near-term falsifiable prediction: a strict null result forgravity-mediated entanglement experiments (the Bose-Marletto-Vedral protocol),because the spacetime metric is updated strictly from actualized vertices andcannot be placed in quantum superposition. Substantial progress on thegenerative measure: the Benincasa-Dowker sign criterion(SBDG(v) > 0) provides the discrete actualization filter,yielding a Poisson-CSG formula cₖRA(x) ∝ e⁻μμkwith μ = λ Vcoh pₜh that is local andenvironment-dependent, recovering dₛ = 3 in dense environments anddₛ = 2 (Durhuus-Jonsson-Wheater) in sparse ones.
This paper develops a discrete, information-theoretic framework in which physical reality is modeled as a lattice or relational graph of interacting “space cells,” each evolving by local update rules. The framework treats space as an active information-processing substrate rather than as a passive background. Time is modeled as an ordering of state transitions rather than as a fundamental substance. Energy is provisionally associated with event density, update rate, action flow, or structured information-processing intensity, with Planck’s constant interpreted as a conversion scale between discrete transitions, phase, and action. The paper combines formal mathematical development with a summary of toy-model probes used to test whether the framework can support the kinds of structures required of a physical theory. Mathematically, it distinguishes theorem-level consequences of local/unitary dynamics from continuum-limit derivations and from simulation-supported but still speculative model-selection branches. Finite-radius local updates imply causal cones; unitary updates preserve norm; local trace-preserving operations preserve no-signaling at the reduced-state level; split-step quantum-walk updates support Dirac-like low-momentum continuum behavior; and Schrödinger-like dynamics arise as a nonrelativistic positive-energy envelope approximation rather than as the most immediate continuum limit. The space-cell framework is organized around two candidate geometric realizations. A distortable-cell model assigns deformation, strain, connection, or topology-bearing degrees of freedom to cells and links. An alternative extrinsic χ-compression model assigns an additional internal scalar coordinate , interpreted as compression, event-density elevation, hidden displacement, or update-rate modulation. The χ option is not initially treated as a literal fourth spatial dimension; it is a parsimonious internal state variable to be compared against deformation-based models under causal, weak-field, Lorentz-like, source-specific, and false-source controls. The toy-model program summarized here tests whether local update rules can generate stable, bounded, identity-preserving informational structures that survive perturbation, scattering, false-carrier pressure, and geometry-like coupling. These simulations do not prove that nature uses space cells, but they have produced mechanism-level evidence for relational identity preservation, local reconstruction, false-carrier rejection, conservation-ledger requirements, photon-like interaction bookkeeping, and χ/deformation model-selection criteria. This paper does not claim to have derived the Standard Model, full quantum field theory, or the Einstein field equations. It presents a staged mathematical and computational research framework. The strongest current claim is that local information-processing rules can be formalized in ways that recover several necessary structural features—locality, conservation-like invariants, causal propagation, no-signaling compatibility, Dirac/Schrödinger continuum regimes, and candidate weak-field geometry equations—while toy-model branches provide constrained tests of whether those structures can support physically relevant informational excitations.
This framework preserves the empirical success of existing physical theories while proposing an alternative set of foundational assumptions from which their standard formulations emerge as effective limits. Abstract — Key Innovative Points Discrete Updating FabricThe theory postulates a fundamental discrete fabric whose elementary constituents evolve through local update processes, replacing continuous fields and background spacetime as primary entities. Irreversible Local Dynamics as FundamentalUnlike standard approaches based on unitary or reversible evolution, irreversibility is taken as ontological. Physical law emerges from irreversible local updates rather than from imposed symmetries or variational principles. Emergent Time and SpacetimeTime is not assumed as a fundamental parameter but arises from the counting of update events. Spacetime geometry emerges as a coarse-grained description of update activity across the fabric. Quantum Probability from Microstate CountingQuantum probabilities, including the Born rule, emerge from combinatorial counting of compatible microstates of the fabric, rather than being postulated axiomatically. Gravity as Update-Rate ModulationGravitational phenomena are interpreted as variations in local update rates, leading to effective curvature, time dilation, and relativistic behavior at macroscopic scales. Mass as Resistance to UpdateMass and inertia arise from stable topological structures within the fabric that resist updates, providing a dynamical origin of mass without introducing fundamental mass parameters. Fundamental Dissipation and IrreversibilityDissipation is intrinsic to the fabric dynamics and not an emergent statistical effect. The arrow of time follows directly from the irreversible nature of local updates. Extension Beyond Fundamental PhysicsThe same discrete framework accounts for macroscopic dissipative phenomena—such as friction, stick–slip dynamics, superlubricity, growth, and self-organization—linking fundamental physics and material behavior within a single process-based model. iversality Without Fundamental SymmetryLarge-scale physical laws emerge as dynamical attractors of the updating fabric, arising through elimination of unstable configurations rather than enforcement of fundamental symmetries. Emergent Rules Beyond the Born Rule in the Unified Fabric Framework The same discrete-fabric + local-update + coarse-graining structure generates multiple quantum rules without postulation. 1. Schrödinger Dynamics as an Emergent Long-Wavelength Limit Local deterministic updates on a discrete fabric admit spectral modes.In the long-wavelength limit, their evolution converges to a Schrödinger-type equation. No quantum dynamics is postulated.Only update rules and spectral structure are assumed. 2. Superposition from Coarse-Grained Microstate Counting Macroscopic amplitudes arise as sums over compatible microstates.Linearity follows from additive contributions at the amplitude level. Superposition is therefore emergent.It reflects coarse-graining, not a fundamental axiom. 3. Interference as Cross-Terms in Microstate Combinatorics Probabilities are quadratic because amplitudes sum before squaring.Cross-terms correspond exactly to interference effects. Interference is not assumed.It is a combinatorial consequence of microstate superposition. 4. Tensor Product Structure and the Origin of Entanglement Composite systems correspond to composite regions of the fabric.Global microstates factorize only if compatibility constraints separate. Entanglement arises when constraints couple subsystems.It is structural, not mysterious. 5. Decoherence from Phase Inaccessibility Observers access only coarse-grained variables.Rapidly varying microstate phases average out. Off-diagonal terms are dynamically suppressed.Decoherence emerges without postulation. 6. Measurement Collapse as Constraint Reduction Measurement is an interaction that reduces compatible microstates.The effective state updates accordingly. Collapse is not a new law.It is constraint updating under coarse-graining. 7. The Arrow of Time from Asymmetric State Counting Entropy is defined as the logarithm of compatible microstates.Local updates generically move toward larger compatible sets. Irreversibility is structural.It does not rely on subjective ignorance. 8. Coulomb Friction from Discrete Event Statistics Friction equals dissipated update energy per unit distance.The Coulomb law emerges from counting active interfacial events. The friction coefficient is not fundamental.It decomposes into microscopic event parameters. 9. Superlubricity as the Event-Free Limit Superlubricity occurs when locking events are suppressed.Dissipation is rare, not forbidden. This is a limit regime, not an exception.It confirms friction as emergent. 11. Conservation Laws from Update Invariance If the update rule is invariant under local transformations,conserved quantities emerge automatically. Noether’s theorem becomes emergent.Symmetry is a property of the update, not an axiom. 12. Classical Determinism from Phase Averaging At large scales, phase information becomes inaccessible.Only expectation values survive. Classical trajectories emerge statistically.Determinism is an effective limit. 13. Locality from Finite Update Propagation Updates propagate only through neighboring fabric nodes.Information speed is bounded. Causality is structural.Nonlocality is only apparent at coarse scales. 14. Emergent Speed Limit (c) The maximum update rate defines a universal speed.No signal can exceed it. The speed of light is not fundamental.It is a fabric update bound. 15. Metric Geometry from Update Delays Spatial curvature corresponds to spatially varying update rates.Time dilation is an update slowdown. Geometry is dynamical.The metric is emergent. 16. Gravity from Update Resistance Mass corresponds to structures resisting updates.Nearby updates slow down in response. Gravitational attraction emerges.No force field is postulated. 17. Equivalence Principle as a Structural Identity All stable update-resisting structures slow updates identically.Their response is universal. Inertial and gravitational mass coincide.Equivalence is automatic. 18. Quantization from Discrete Spectrum A finite update lattice admits discrete eigenmodes.Energy levels are quantized. Quantization is not imposed.Continuum is an approximation. 19. Noise Spectra (1/f) from Avalanche Dynamics Update cascades produce scale-free event statistics.Long-range correlations appear. 1/f noise is generic.It signals discrete underlying dynamics. 20. Criticality without Tuning The fabric naturally operates near instability thresholds.Small perturbations trigger cascades. Self-organized criticality emerges.No parameter tuning is required. 21. Thermodynamic Laws as Counting Theorems Temperature measures update activity density.Heat is disordered update flow. Thermodynamics is not independent.It is bookkeeping of updates. 22. Growth and Morphogenesis from Update Bias Directional update biases produce structured growth.Forms emerge without templates. Morphogenesis is dynamical.Shape follows update flow. 23. Fine-structure value and other unknow meaning The fine-structure value (~137) corresponds to the effective degeneracyof coherently contributing update configurations in an elementary coupling process.Proton–electron mass ratio the number of internal update cycles required to stabilize a topological vortex (proton), and a simple oscillatory update mode (electron). Mass measures cumulative resistance to updates. Lepton mass hierarchy Different stability thresholds of the same update pattern. Each mass corresponds to a different coherence regime.→ Families are metastable realizations of one structure. Reduced Planck constant Energy × time associated with one elementary update event. → ħ is the discrete unit of updating. Speed of light Maximum update propagation speed across the fabric. → c is the causal limit of the fabric. Bekenstein–Hawking entropy Number of blocked or saturated update configurations at the horizon. → An event horizon is an informational saturation boundary. Universal critical exponents They arise from the topology of update avalanches,independent of microscopic details. → Criticality is a natural fabric regime. Explanations Rarely Given in Existing Theories 1. Why probabilities are quadratic and not cubic or linear Most theories postulate P=∣ψ∣2P=|\psi|^2P=∣ψ∣2.Here it follows from coherent counting plus phase cancellation. The square is not a choice.It is the minimal stable coarse-graining. 2. Why quantum phases are physically unobservable but indispensable Phases affect interference but not outcomes directly.They label micro-configurations, not macrostates. Phase is structural memory.Measurement erases access to it. 3. Why constants are dimensionless and few Only ratios of update counts survive coarse-graining.Dimensional parameters wash out. Dimensionless constants are structural.They encode geometry, not dynamics. 4. Why “free parameters” cluster around simple numbers Many constants are order-one ratios or small inverses.They reflect combinatorial suppression. Fine tuning is apparent.It is state counting in disguise. 5. Why quantum randomness is stable and reproducible Randomness is not noise.It is deterministic micro-dynamics seen through coarse-graining. Statistics are invariant.Details are inaccessible. 6. Why identical particles are truly identical Microstates differ, macrostates do not.Labels are erased by update symmetry. Indistinguishability is enforced.It is not a postulate. 7. Why spin is quantized and half-integer values exist Spin counts topological winding in update cycles.Only discrete windings are stable. Half-integer spin reflects double-cover topology.No mystery remains. 8. Why gauge free
## Title The Relational Closure Framework: From Relations to Matter via Causal Consistency ## Authors Mingdong He (Independent Researcher, ORCID: 0009-0009-5176-7571) ### Overview This deposit contains the complete source code and compiled PDF of the Relational Closure Framework (RCF) version 2.0C, a relational approach to the foundations of physics developed as a candidate contribution to Hilbert's sixth problem (the axiomatization of physics). The framework proposes that the universe is constituted by **relations** rather than objects. Stable relations form **closures** (self-consistent cycles); closures generate topological invariants (holonomies); and these invariants underpin all physical structures—conservation laws, the least-action principle, the Born rule, dimension, geometry, and matter—as emergent phenomena of the closure network at different scales. ### What is new in v2.0C Version 2.0C introduces a **causal consistency principle**: physical existence requires causal consistency as a precondition, not as a consequence of continuous spacetime. What appears as continuity is reinterpreted as **pseudo-continuity**—the statistical artifact of mutually constraining discrete closures. This reframing dissolves (rather than solves) the continuum-limit problem that has obstructed discrete approaches to physics for decades. Key new results in v2.0C: 1. **Causal consistency as physical precondition** — The speed of light is derived as the enforcement mechanism for causal consistency (not an arbitrary postulate). 2. **Randomness from constraint gaps** — Quantum probability arises naturally from the incompleteness of discrete constraints, not from an axiom. 3. **Wave function as constraint-gap envelope** — The wave function exists because the network is discrete; it "waves" because holonomy phases interfere; it is non-classical because it carries probability, not energy. 4. **Schrödinger equation from pseudo-continuity** — Via the Madelung transformation, the Schrödinger equation is shown to emerge from: (i) holonomy action stationarity (Hamilton–Jacobi), (ii) constraint-gap-induced probability density, and (iii) Noether conservation (continuity equation). The quantum potential is interpreted as the signature of pseudo-continuity failure. 5. **Fields as long-range constraint mechanisms** — All fundamental fields are intrinsically long-range because causal consistency is a global requirement. The de Sitter entropy (~10^122) is conjectured as the information-theoretic capacity bound on causal constraints. ### Core results (retained from v1.2) - A **generalized Noether theorem**: conservation is identified with the kernel of the exchange map, derived from axioms without assuming symmetry. - A **least-action principle**: the action is proved to be necessarily a function of closure holonomies; δS = 0 is equivalent to a non-abelian Kirchhoff law; the continuum limit recovers Maxwell and Yang–Mills equations. - The **Born rule**: stochasticity arises from the observer as an open dynamical system (Nakajima–Zwanzig); the square law |α|² is forced by the Gleason–Busch theorem under finite additivity. - The **Z₃–γ₅ algebraic correspondence**: a strict algebraic identity linking the minimal relational closure (3-cycle) to the Dirac chirality operator. - A **quantum error correction correspondence**: the Gauss-law operator is structurally identical to the toric-code stabilizer; vacuum stability is topologically protected. ### AI use disclosure This manuscript was prepared with the assistance of AI language models (Claude/ChatGPT/Gemini families) for typesetting, reference formatting, and consistency checking. All theoretical content—axioms, proofs, conjectures, and the causal consistency principle—is the sole intellectual contribution of the author. AI tools were used as a writing assistant, not as a source of scientific ideas.
The causal-set programme proposes that spacetime is, at bottom, a discrete poset whose Lorentzian geometry emerges, endowed with a covariant sequential growth dynamics. It leaves open, however, two points that an ontology must settle: the status of the "becoming" of growth (a computational procedure or a real process?), and the basis of its quantum version (quantum sequential growth, QSG, does not specify the basis of the histories). We show that the theory Time–Actualization (TA) proposes an ontological answer: becoming is posited as real actualization, while the basis is selected by the couplings carried by the causal past, where that monitoring supplies a sharp basis. This identifies an environment within the ontology; it does not derive its coupling content or construct the full quantum dynamics. We present the interface as a consistency bridge, not a refoundation. The emergent geometry and its Hauptvermutung remain inherited, and the dynamical law of actualization remains open. The proposed unification concerns a common process reading of flashes, system actualizations and causal-set growth; their different rates still require an explicit interface.
