This article initiates the Structural Compatibility series within the broader finite-horizon programme. It investigates the structural conditions under which aggregation on a normalized persistence leaf admits a linear normal form. Starting from finite-horizon persistence as a minimal admissibility condition for identifiable regimes, the paper introduces maintainability under perturbations and combinability as structural requirements for internal reorganization. It then restricts attention to an enriched branch in which the normalized persistence leaf is assumed to admit an affine model of internal reorganization. Within this explicitly selected affine setting, the main result is a conditional rigidity theorem: under affine-leaf regularity, scale invariance, and a global bi-affine regularity hypothesis, any admissible aggregation law on the persistence leaf reduces to a linear normal form in affine coordinates. The paper does not claim to derive the full quantum formalism. Rather, it isolates a minimal linear backbone that may underlie richer realizations. Standard quantum theory is therefore discussed only as a compatible enriched realization built on top of this structural pattern, not as a result derived in full. The transition from weaker infinitesimal compatibility conditions to global bi-affinity is identified as the main open integration problem. In this sense, the article should be read as a foundational structural preprint and as the entry point of an enriched branch developed further in the subsequent papers of the series.

This preprint develops the second step of the Structural Compatibility series. Starting from the affine persistence framework established in Structural Compatibility I, it examines the consequences of recurrent compact internal symmetry acting within an admissible persistence regime. The article shows that recurrent internal affine flows have compact closure, and that under a rank-one assumption the connected compact internal symmetry reduces to a circle. After fixed-point reduction and linearization, this symmetry acts on the underlying real state space through orthogonal rotation sectors. On the rotational sector, the action induces a canonical complex structure, an invariant Hermitian comparison form, and a unitary realization of the internal symmetry. Under an additional phase-uniformity assumption, the circle action becomes a genuine global phase acting on the whole state space. This makes it possible to pass to the associated complex projective state space, which then inherits the standard Fubini–Study Kähler geometry. The scope of the result is strictly kinematical. No probabilistic axiom, measurement postulate, or dynamical equation is assumed. The paper does not derive full quantum theory, but identifies a structural route from an affine real persistence regime to the minimal complex-projective kinematical architecture usually taken as one of the starting points of quantum formalism. This article is part of the Ranesis framework, developed by Alexandre Ramakers.
Structural Compatibility III develops the third step of the Structural Compatibility series. Starting from the complex Hermitian-projective persistence regime obtained in Structural Compatibility II, it identifies the minimal operatorial layer admissible within that setting. The article shows that the infinitesimal internal generators compatible with the inherited Hermitian comparison structure are exactly the Hermitian endomorphisms of the finite-dimensional complex state space. These are introduced as structural observables, understood not as primitive measurement objects but as generators of one-parameter unitary internal flows. From this identification, the paper develops the corresponding spectral architecture. Every structural observable admits a decomposition into orthogonal invariant sectors, together with a complete family of spectral projectors. These projectors induce canonical projective weights on ray space, measuring the relative Hermitian contribution of a ray to each spectral sector. The analysis is then extended to compatible families of observables, yielding joint spectral sectors and multiparameter unitary actions generated by commuting Hermitian operators. A final optional layer shows how this operatorial framework may be coupled to additional ray-level coherence and horizon descriptors coming from the broader finite-horizon maintenance programme. When these descriptors are invariant under a given unitary action, the observable scalar associated with that action extends to a conserved maintenance-compatible quantity. The scope of the result remains strictly kinematical and operatorial. No Born rule, no measurement postulate, no collapse dynamics, and no distinguished physical Hamiltonian are assumed. The paper does not derive a complete physical theory of observables, but isolates the minimal Hermitian-projective operatorial architecture structurally available once the complex persistence regime has been established. This article is part of the Ranesis framework, developed by Alexandre Ramakers.
Structural Compatibility IV develops the fourth step of the Structural Compatibility series, explicitly on the basis of the broader Finite-Horizon Structures I–VI framework. Starting from the Hermitian-projective operatorial regime established in the preceding Structural Compatibility articles, it addresses the first major question left open at the end of Structural Compatibility III: what becomes of that operatorial regime when the supplementary maintenance conditions cease to remain admissible. The article introduces an explicit notion of stable maintenance regime and defines maintenance breakdown as a loss of admissible continuation within that regime. It shows that such breakdown should be understood not as annihilation of the state and not as a primitive collapse postulate, but as a regime transition: a previously admissible structural setting reaches a boundary beyond which the same maintenance-compatible description can no longer be sustained. To make this transition analyzable, the paper develops a threshold structure through a stability margin and shows that threshold crossing cannot, in general, be produced by the internal unitary evolution alone when the maintenance scalar is preserved. This leads to the introduction of a contextual coupling parameter and an adaptive admissibility threshold, providing a minimal structural mechanism for regime exit without modifying the inherited Hermitian generator. On this basis, the article derives a regime-dependent spectral filtering principle. When the full state becomes globally inadmissible, admissible continuation is restricted to those spectral sectors that remain individually below the updated threshold. The result is therefore a structural theory of post-breakdown sectorial restriction: threshold crossing does not yet determine a unique outcome, but it does reduce the admissible continuation space to a stable spectral subspace. An optional refinement then introduces robustness-based sector weights, understood not as empirical probabilities but as comparative indices measuring how deeply surviving sectors remain inside the admissible domain. Under additional projective-Hermitian assumptions, the same surviving sectors also carry canonical quadratic projective comparison quantities associated with the inherited spectral projector structure, distinct in general from the robustness weights themselves. The scope of the article remains deliberately limited. No Born rule, no complete collapse dynamics, no unique microscopic selection mechanism, and no distinguished observational coupling are assumed or derived. The paper does not claim to provide a full theory of measurement, but rather isolates the missing transition layer between the stable Hermitian-projective operatorial core of Structural Compatibility III and a first structural account of admissibility loss, contextual threshold crossing, and post-breakdown spectral restriction. This article is part of the Ranesis framework, developed by Alexandre Ramakers.
A structural derivation of spectral structure and quantization is obtained from minimal requirements on discernibility and persistence under variation. Rather than postulating quantum degrees of freedom, operators, or Hilbert space, the analysis identifies which assumptions are required for eigenstructure to arise as a consequence of stability under irreversible loss. Building on prior results establishing accumulated loss, path dependence, and curvature as necessary consequences of persistence, the paper introduces a clear admissibility ledger. Under explicit conditions—ordered variation, local loss density, and a quadratic stability regime—the second variation of accumulated loss defines a curvature operator that classifies admissible deviations by their susceptibility to persistence loss. Eigenmodes emerge as stability classes selected by persistence filtering, not as fundamental postulates. Discrete spectra appear only when admissibility conditions enforce effective compactness. Additional restrictions concerning closed continuations and phase-valued transport lead to a closure condition under repeated traversal, reproducing Bohr-type quantization as a conditional consequence rather than an axiom. Global spectral weights and regularization are introduced solely as technical bookkeeping devices when persistence comparison is extended to families of modes. The framework deliberately separates structural derivation from physical interpretation. Hilbert space structure, probabilistic interpretation, and standard quantum dynamics arise only under further assumptions and are not required for spectral stability itself. Standard quantum mechanics is recovered as a specialization of the general framework under additional linearity, normalization, and interpretive assumptions. The paper isolates the minimal structural content underlying eigenstructure and quantization, making explicit which assumptions are responsible for each step. It stops short of system-specific applications, but the entropy-weighted variational object derived here serves as the foundation for predictive extensions developed in companion works, including corrections to tunneling behavior, interference suppression, and collapse-like phenomena emerging from resolution instability.
The present work investigates the representational consequences of realization-dependent accessibility organization under globally incomplete endpoint reduction. The preceding papers of the Physics of Difference series established that admissible realizations connecting identical endpoint accessibility relations may nevertheless remain compositionally distinguishable within realization organization itself. In particular, realization-dependent distinctions may remain globally persistent whenever endpoint reduction fails to extend to a globally compatible compositional reduction structure.Under such conditions, endpoint accessibility relations no longer provide a structurally complete representation of realization organization. The present analysis therefore investigates what representational organization becomes necessary once realization multiplicity remains irreducible under endpoint accessibility reduction.The analysis shows that any representation framework preserving realization organization faithfully must simultaneously support realization distinguishability, compositional compatibility, multiplicity-preserving aggregation, decomposability, and recombinational stability. These constraints naturally motivate additive decomposable representation.Importantly, additive representation is not introduced as an independent quantum-theoretic postulate. Rather, it emerges structurally as a multiplicity-preserving response to reduction obstruction itself.The resulting framework admits several quantum-like organizational features. In particular, realization composition induces residual compositional organization, manifest accessibility restriction generates projection-like representational structure, and compatibility-preserving aggregation admits naturally emerging quadratic organizational forms.At the same time, the framework remains intentionally weaker than conventional quantum mechanics. The present analysis does not assume or derive Hilbert-space structure, Schrödinger dynamics, unitary evolution, or Born-rule probability interpretation.The framework should therefore be interpreted not as a reconstruction of quantum mechanics itself, but as the identification of minimal representational conditions under which quantum-like organizational structure begins to emerge from irreducible realization multiplicity under compositional accessibility organization.
This paper derives a persistence-weighted path integral from first principles of coherent comparison under composed admissible variation. Rather than postulating probabilistic, geometric, or dynamical structure, the analysis asks which bookkeeping devices are unavoidable if comparison is to remain well defined when admissible variations are recomposed, refined, or reordered. Starting from minimal operational requirements—discernibility, admissible variation, and persistence—the paper shows that path dependence, accumulated loss, stationarity, and quadratic stability classification are structurally forced. An accumulated loss functional emerges as the minimal additive bookkeeping required for coherence, and persistence weighting arises as a monotone representation of the induced ordering on admissible paths. Under additional stability requirements, the exponential weighting appears as a canonical representative compatible with arbitrary recomposition. Second-order variation around persistence-stationary paths yields a quadratic stability form, which can be repackaged as a curvature operator acting on admissible perturbations. Spectral structure then appears as a classification of persistence-relevant deviations, without presupposing geometry, dynamics, or operator postulates. Familiar formalisms—path integrals, entropy-weighted amplitudes, and spectral descriptions—arise only as restricted realizations once further admissibility, locality, and representational constraints are imposed. The entropy-weighted Feynman path integral is recovered explicitly as such a downstream specialization, with all additional assumptions labeled. The result is not a constructive physical model but a boundary-forming derivation: it fixes which structures are forced by coherence of comparison and which questions are deferred to later, more constrained analyses. The paper provides a foundational anchor for subsequent applications that treat persistence-weighted amplitudes and curvature operators as fixed inputs rather than postulates.
