Admissibility Physics — Entropy, Time, and Accumulated Cost (Ledger Works) This Zenodo community collects research outputs associated with Admissibility Physics, with primary focus on Paper 3 — Entropy, Time, and Accumulated Cost as Capacity Accounting and the ledger structure it establishes. Paper 3 introduces the accounting layer of the framework. Building on the finite enforceability principle (Paper 1) and non-closure under composition (Paper 2), it defines entropy as irreversibly committed correlation capacity at interfaces. Entropy is not treated as uncertainty, probability, or coarse-grained ignorance, but as a pre-probabilistic ledger quantity: capacity that has been committed to stabilizing distinctions and can no longer be freely reallocated. From this definition, Paper 3 derives irreversibility as a structural consequence of record formation. When correlations become redundantly enforced across interfaces, the capacity supporting them becomes locked, restricting future admissible configurations. The accumulation of such irreversible commitments induces a partial ordering on admissible states, which is identified with time. Time is not assumed as a background parameter; it emerges wherever irreversible ledger commitments occur and is undefined where they do not. No assumptions are made about dynamics, spacetime geometry, probability, or quantum mechanics. The paper establishes the ledger constraints that any subsequent representation must respect, regardless of the formalism used. Area laws, saturation behavior, and Page-like transitions arise directly from interface-localized capacity and non-closure, without appeal to microstates or statistical ensembles. All subsequent works in this community rely on the ledger structure introduced in Paper 3. Later papers show how quantum probabilities, variational dynamics, and geometric description become admissible only in regimes where ledger commitments are smooth and locally additive, and how these representations fail at saturation boundaries, horizons, and measurement-like transitions. This community serves as a curated, citable archive centered on the ledger foundations of Admissibility Physics. Paper 3 functions as the accounting backbone of the program: the point at which finite enforceability becomes entropy, irreversibility, and temporal structure. Core papers are frozen where noted; companion papers, mathematical appendices, figures, and computational artifacts document derivations, regime conditions, and structural consequences.

Admissibility Physics — Quantum Structure from Finite Enforceability (Paper 5) This Zenodo community collects research outputs associated with Admissibility Physics, with primary focus on Paper 5 — Quantum Structure from Finite Enforceability and the derivation of quantum mechanics as an admissible representational regime. Paper 5 shows that the mathematical structure of quantum mechanics—Hilbert space, linearity, inner products, tensor products, unitary evolution, CPTP maps, and the Born rule—is not postulated, but forced by admissibility once coherent, jointly enforceable distinctions exist under finite correlation capacity. Quantum structure emerges as the unique bookkeeping required to represent interference, refinement, and recombination while preserving admissibility. The derivation does not assume probability, measurement postulates, dynamics, or spacetime geometry. Probability enters only as a secondary representation, with the Born rule arising uniquely from admissibility invariance and refinement consistency. Measurement is treated as a regime transition associated with saturation and record formation, not as a fundamental collapse mechanism. Quantum mechanics is shown to be conditionally valid: exact in regimes where coherence and non-saturation permit admissible composition, and structurally inapplicable where capacity is exhausted. Monogamy, entanglement limits, and decoherence follow from non-closure under composition and finite interface capacity, rather than from quantum axioms. All subsequent works in this community rely on the quantum-admissible representation established in Paper 5. Later papers show how variational dynamics and spacetime geometry arise as further conditional representations layered on top of quantum structure, and how quantum description itself fails at saturation boundaries, horizons, and measurement-like events. This community serves as a curated, citable archive centered on the derivation and limits of quantum structure within Admissibility Physics. Paper 5 functions as the representational keystone of the program: the point at which finite enforceability yields the quantum formalism without postulation. Core papers are frozen where noted; companion papers, mathematical appendices, figures, and computational artifacts document derivations, regime conditions, and testable consequences.
Technical Supplement to Paper 3 of the Admissibility Physics Framework (APF), Ledgers: Admissible Dynamics, Entropy, and the Arrow of Time. Paper 3 promotes complete positivity from postulate to theorem. It derives the directed-enforcement multiplier κ = 2 from irreversibility plus locality. It identifies von Neumann entropy as committed capacity. It elevates the Admissibility-Capacity Ledger to a first-class object with six regime projections and four consistency identities. Eight formal sections. §1 Complete positivity as theorem. TCPTP derives the Kraus-form evolution ℰ(ρ) = Σk Kk ρ Kk† with Σk Kk† Kk = 𝟙 directly from PLEC, comparing the result to the Stinespring–Choi–GKSL infrastructure (Stinespring 1955, Choi 1975, Lindblad 1976, Gorini–Kossakowski–Sudarshan 1976, Kraus 1983). §2 Directed-enforcement multiplier. Tκ proves κ = 2 from irreversibility plus locality. §3 Von Neumann entropy as committed capacity. Tentropy identifies S(ρ) = −Tr(ρ log ρ) with the committed-capacity functional, anchored to the strong-subadditivity backbone (Lieb–Ruskai 1973, Wehrl 1978). §4 Second law and arrow of time as structural consequences of Lirr, not phenomenological postulates. §5 ACC and horizon entropy. SBH = A/4 with the formal proof of the ½ × ½ bookkeeping. §6 The Admissibility-Capacity Ledger. TACC unification elevates (K, deff) to a single ledger with six regime projections πT (thermodynamic), πG (gauge), πQ (quantum), πF (fermion), πC (cosmological), πA (action), and four consistency identities I1, I2, I3, I4 linking holographic, gauge–cosmological, thermo-quantum, and action–thermo readings. §7 Interface-sector bridge. Tinterface sector bridge is the subspace-level refinement. The two recurring "42"s in the codebase — the T11 cosmological partition and the Lself exclusion commitment decomposition — co-witness on the same 42-dimensional subspace Vglobal ⊂ V61. §8 Fisher-information metric. The Fisher metric on admissible states. RG flow expressed as Fisher gradient descent (Braunstein–Caves 1994, Petz 1996, Amari–Nagaoka 2000). Red-team appendix flags four additional hypotheses at point of use: H1 (Markovian-composition closure), H2 (Hamiltonian-constraint redundancy), H3 (constraint-functional monotonicity), H4 (subspace-level uniqueness of Vglobal).

Description This paper develops a formal calculus of admissible correlation, providing the technical backbone for a constraint-first approach to physical description. Building on a conceptual framework in which enforceability and finite correlation capacity are taken as primitive structural requirements, the present work makes these notions explicit, operational, and compositional. Correlations are treated as primitive relational constraints enforced across interfaces endowed with finite capacity. Admissibility is defined as joint enforceability under these capacity limits and is shown to be inherently non-closed under composition. Correlation capacity is formalized as a finite, interface-localized resource whose saturation and redistribution determine which correlation sets can coherently exist. This yields a precise, pre-dynamical criterion for physical feasibility that precedes probability, stability, and dynamical law. Within this calculus, regime transitions arise when admissible correlation sets change due to capacity reallocation rather than dynamical evolution. The ordered loss of descriptive structures—global states, subsystem factorization, metric geometry, and time itself—is characterized as a consequence of finite enforceability rather than as a breakdown of physical law. Geometry emerges as an efficient representation of coordination cost where capacity gradients are smooth, while entropy is identified with interface capacity governing record formation and exclusion. The calculus introduces no new dynamics, modifies no existing physical theories, and commits to no microscopic ontology. Its role is structural: to delineate the kinematic envelope within which any coherent physical dynamics must operate. Quantum mechanics and general relativity are shown to function as admissibility-preserving frameworks within the regimes where their descriptive assumptions remain enforceable. This work is intended to stand alone as a technical contribution while serving, together with its companion foundational paper, to clarify the limits of physical description and the conditions under which familiar physical structures emerge, persist, and fail.

Admissibility Physics derives the Standard Model gauge group, fermion content, quantum formalism, Lorentzian spacetime, the Einstein field equations, the cosmological constant, and the neutrino, strong-CP, and dark sectors from a single assumption — that enforcement is finite at every causally connected region — with zero free parameters.

Physical law is usually formulated as a set of dynamical rules acting on states within a fixed space of possibilities. This work argues that a more primitive constraint precedes dynamics: the restriction on which correlations and distinctions may meaningfully exist at all. The paper introduces the Admissibility–Entropy Structure (AES), a pre-geometric framework that cleanly separates admissibility (what correlations are possible) from entropy (finite correlation capacity) and probability (conditional statistical description). Within AES, entropy measures correlation capacity rather than likelihood, probability is defined only where multiple admissible alternatives coexist, and realizable correlation between regions is bounded by the minimal separating interface. Spacetime geometry, locality, and causal structure are shown to arise as effective representations of these constraints, rather than as fundamental ingredients. No new dynamics, entities, or probabilistic postulates are introduced. The framework yields sharp and non-negotiable discriminators: probability without entropy, geometry without capacity, and unlimited correlation are forbidden in principle. By isolating the invariant constraints that underwrite meaningful physical description, this work provides a minimal foundation for thermodynamics, quantum theory, and spacetime structure, clarifying their conceptual order without modifying established physical laws.

This paper introduces a constraint-first framework for physical law based on a single structural requirement: that distinctions and correlations be enforceable without contradiction under finite capacity. Rather than proposing new dynamics, entities, or microscopic mechanisms, the work reframes foundational questions in physics by asking a prior question—under what conditions is physical description itself possible? Central to the framework is the recognition that correlation enforcement cannot be unlimited. From this finiteness follows a notion of admissibility, separating correlation structures that can be jointly realized from those that are structurally incoherent, independent of probability or dynamics. Geometry, time, entropy, and global state descriptions are treated not as universal primitives, but as regime-dependent representations that emerge when enforcement constraints can be smoothly distributed—and fail when they cannot. Within this perspective, long-standing foundational puzzles—such as the arrow of time, entropy bounds, horizon paradoxes, and the breakdown of global descriptions—are reinterpreted as signals of regime mismatch rather than failures of physical law. Apparent paradoxes arise when descriptive tools are extrapolated beyond the regimes in which their enforcement is possible. The paper is deliberately pre-dynamical. It does not modify quantum mechanics or general relativity, nor does it derive specific equations or predictions. Its contribution is structural: to articulate the minimal conditions that any coherent physical description must satisfy, and to clarify why familiar physical structures appear where they do, persist where they can, and fail where they must. This work serves as the conceptual foundation for a companion technical paper that formalizes admissibility and finite correlation capacity as a calculus. Together, the papers aim to delineate the boundary between meaningful physical description and questions that cannot be consistently posed. About the series.

Paper 16 of the Admissibility Physics Framework (APF), Markov Breakdown and the Hard Problems. When the enforcement Markov condition fails, the substrate can no longer maintain a record — and that failure is where the framework locates the measurement problem, the arrow of time, and the classical limit. What it contains. The record-maintenance condition as a perfect-error-correction (Markov) condition; the A1-derived record-survival threshold (E/C)*n = (2n−1)/(2n−1), giving 5/7 at n = 3; and the Markov-breakdown transition with mean-field exponents β = γ = 1. Recent work fixes the beyond-mean-field class: by the forced-universality criterion the local-stabilizer (surface/toric-code) substrate sits in sub-family B (2D percolation), and the saturation-percolation bridge measures ν̂ = 1.44 ± 0.12 ≈ 4/3 at that threshold. The quantum–classical boundary. The record-survival rate collapses as interface count grows — large systems decohere at once, microscopic ones stay robust — which is the framework's account of why big things are classical. Honest non-claims. The mean-field β = γ = 1 is the approximation; the conditional-mutual-information variance exponent at the threshold still needs the percolation-class field theory. The measured correlation-length exponent ν and the CMI-variance exponent are kept distinct. About the APF series. The Admissibility Physics Framework derives Standard Model and cosmological structure from a single primitive — finite enforcement capacity — through a chain of papers plus a machine-verifiable engine. Each paper has a main text and, where applicable, a Technical Supplement, deposited on Zenodo and collected in the admissibility_physics community; the canonical engine (APF-Engine v24.3.427, 3,918 bank-registered checks) backs every quantitative claim.
