Description This record contains the revised version of Paper 15 in the Fundamental Being Space (FBS) Theory series. In this revision, the updated contents of Papers 12–14 are reflected, and state formation on the Σ side, state projection to the ordinary-spacetime side, observation-output formation after projection, and the classification of multiple identical projected states are reorganized as distinct stages. The basic relation is organized as follows: internal responses in Σ→ψΣ→ψSi→Xi Here, state projection and observation-output formation are not treated as the same process. The classification of exchange, occupation, and effective projected modes for multiple identical projected states is also positioned as a subsequent stage. On this basis, this paper organizes observability, phase and rotational responses, stabilization and retention, consistency with state projection, and constraint conditions as having distinct roles within the minimal effective action of the interface layer Σ. Furthermore, a finite effective sector is extracted from the broad operator-response structure on the Σ side and connected to a finite-dimensional representation as AΣ→PeffAΣPeff→MΣeff As a specific candidate for this finite-dimensional representation, the 4+3 block structure of a 7×7 response matrix is used. By applying the Schur complement, a general form is shown in which the influence of one finite effective sector remains as a correction to the other effective response through off-diagonal responses. However, the dimension 7 is not regarded as having been newly derived from the minimal effective action or from the selection of the finite effective part. Through this revision, the role of Paper 15 within the FBS Theory research program has also been clarified. The observability structure, spinor-type responses, and classification of multiple identical projected states organized in Papers 12–14 are connected in Paper 15 to the framework of the minimal effective action and finite effective sectors. This provides a bridge to the next stage, Paper 16, where the physical specification of the 7×7 response structure and the connection between quantum-type and gravity-type responses will be examined. This paper does not derive the complete internal structure of Σ, standard quantum mechanics, the Dirac equation, or the spin-statistics relation from first principles. Its purpose is to reorganize the response structures developed in the revised Papers 12–14 under the minimal effective action and to present a finite effective structure that connects to Paper 16.

Description This record contains Paper 12 of the Fundamental Being Space (FBS) Theory series: Born Projection and Observability Mapping in the Interface Layer Σ: An Interpretation Based on 𝓒ΣTΣ → X_i in FBS Theory This paper reinterprets the Born rule as an observability rule from Σ to S_i, based on the mapping structure FBS → Σ → S_i in Fundamental Being Space (FBS) Theory. In standard quantum mechanics, P = |ψ|^2 = ψ^{*}ψ gives the probability density for the complex amplitude ψ. In this paper, this relation is not treated as a rigorous derivation of the Born rule. Instead, it is positioned as a representative form in which the complex and phase structure on the Σ side is projected onto real, non-negative observable quantities on the S_i side. To organize this interpretation, this paper introduces the observability structure 𝓒ΣTΣ → X_i. Here, 𝓒Σ represents the mapping factor, transformation factor, and phase factor in Σ, while TΣ represents the ordering condition that establishes a sequence of observable phenomena. X_i represents observable quantities, effective physical quantities, or real quantities appearing on the S_i side. This paper also connects the structure of observability to λ_h within the seven-constraint mapping structure organized in Paper 10. λ_h is positioned as a constraint component related to quantum action consistency and observability, and the Born rule is treated as a representative projection rule associated with this channel. Furthermore, this paper introduces a working framework in which the seven functions of Σ do not appear on the S_i side in a single step, but are made observable through multiple response stages. This structure can be organized as an internal response matrix of Σ consisting of 7 functions × 7 response stages. However, this paper does not formalize the entire matrix; instead, it focuses only on the response components related to the Born rule, the conjugate structure, and observability. Regarding the measurement problem and quantum entanglement, this paper does not claim to solve them. Rather, it repositions them as problems of the Σ mapping and observability. Standard quantum mechanics is retained as an effective theory on the S_i side, while this paper examines a possible Σ mapping structure that may underlie it. This paper does not replace quantum mechanics. It is a foundational study that reorganizes the Born rule, conjugate structure, quantum probability, the measurement problem, and quantum entanglement within the observability structure of the FBS → Σ → S_i mapping.

The paper reinterprets the Born rule within the FBS → Σ → S_i observability structure while retaining standard quantum mechanics as an effective theory on the S_i side.

This record is retained because published Zenodo DOIs cannot be removed; please cite the canonical record. Technical Supplement to Paper 5 of the Admissibility Physics Framework (APF), Quantum Structure as Least-Cost Admissible Bookkeeping. Paper 5 derives the complete quantum formalism — linearity, complex Hilbert space, tensor products, Born's rule, unitary and CPTP dynamics, measurement as class change, spectral-action internalisation, and UV-completion closure — from PLEC (A1, MD, A2, BW) plus the capacity quantization Ctot = 61, deff = 102 imported from Papers 1–4. The supplement provides self-contained proofs of the theorems compressed to sketch form in the main paper. Linearity from coherent-distinction closure. Tlinearity: if sector states |ψ1⟩, |ψ2⟩ are admissible and coherent-distinction-closed, then their normalised linear combination α|ψ1⟩ + β|ψ2⟩ with |α|2 + |β|2 = 1 is admissible. Complex Hilbert space. THilbert: the state space is a complex Hilbert space ℋ with inner product induced by the cost functional, and the field selection 𝔽 = ℂ is inherited from Paper 1's field-selection tier. Tensor product. Ttensor: composite systems factorise as ℋAB = ℋA ⊗ ℋB under admissibility of joint distinction. Born's rule. TBorn: measurement outcome probabilities are Pr(k | ρ) = Tr(Pk ρ) with {Pk} the projective decomposition operators corresponding to admissible partition classes — derived, not postulated. Unitary and CPTP dynamics. THermitian and TCPTP: admissible state evolution is Hermitian-generated for closed systems and CPTP for open systems, both from minimum-cost bookkeeping. Measurement as class change. Tdecoherence: measurement is the transition from an admissible coherent superposition to an admissible classical register, formalised as a class change on the equivalence structure of admissible states. Spectral-action internalisation. Lspectral_action_internal: the Connes spectral action coincides with the APF partition function under the Boltzmann cutoff. Full proof in Paper 7 Technical Supplement §S.4. UV-completion closure. LQG_P1_closure: the admissibility framework remains consistent under Paper 1's structural extension to UV scales. Explicit countermodels exclude the main published quantum-reconstruction alternatives (Hardy 2001, Masanes–Müller 2011, d'Ariano–Chiribella–Perinotti 2010, Rovelli relational).

This monograph develops a particle-first framework for many-particle quantum mechanics based on finite topological carriers, their actual causal histories, and a physical spacetime–vacuum substrate. The construction retains three physical axioms: microscopic ontic definiteness with finite localization, the physical reality of the substrate, and persistent causal source–response coupling. Euclidean self-return is treated as a geometric condition of a specified substrate realization rather than an additional matter axiom. The framework connects covariant parent dynamics and finite-energy carrier configurations to stratified many-particle configuration spaces, joint histories, preparation measures, probability currents, and conditional phase and Hilbert-space representations. Fixed- and variable-particle-number dynamics are formulated within a common sector-resolved description. Particular attention is given to finite-core interactions, historical memory, collision-induced changes in carrier decomposition, scattering, bound states, resonances, creation, annihilation, and decay. The manuscript presents scattering constructions for specified short-range interaction classes, together with multichannel and three-cluster formulations. Exchange statistics, entanglement, measurement records, kinetic reduction, and collective phenomena are examined as related aspects of the enlarged carrier–substrate dynamics. Local fields, propagators, diagrammatic expansions, and other effective computational tools are introduced downstream as representations on explicitly restricted domains. Their use does not assign independent ontic status to operator-valued fields or internal diagram lines. Mathematical results, physical-realization assumptions, numerical calculations, and empirical validation are distinguished throughout. A complete computational replacement for quantum field theory is not claimed: model-specific interaction kernels, reproducible many-particle calculations, and quantitative comparisons between particle and effective-field descriptions remain central tasks. Owing to the integration of material developed through successive stages of research and revision, the present draft contains some uneven organization, repetition, and discontinuities in its logical presentation. A simplified and reorganized version, with a clearer logical sequence and more concise exposition, is planned for subsequent publication. Keywords Finite topological carriers; causal histories; many-particle quantum mechanics; stratified configuration spaces; historical memory; collision and scattering; variable particle number; quantum reactions; exchange statistics; effective field representations.
This registration preserves a consolidated, time-stamped version of the principal works comprising the Necessity programme in natural physics. The collection includes *The Necessity of Structure*, *The Necessity of Quantum Structure*, *The Necessity of Natural Physics*, the finite-response master-equation work, and related supporting papers. Taken together, these works develop a necessity-first method for physical theory. Rather than beginning with spacetime, matter, fields, particles, observers, information, probability, or established mathematical structures as unexplained assumptions, the programme asks which structures must exist for a physical world to be coherent, distinguishable, and empirically describable. Each subsequent structure is admitted only where it can be justified by the preceding requirements. The programme proceeds from minimal structural conditions through quantum structure, composition, localisation, interaction, gravitation, cosmology, and finite numerical response. The master-equation work provides a compact mathematical expression of the programme’s finite-response structure and connects the general framework to identifiable physical regimes and numerical tests. The remaining papers develop particular consequences, applications, and consistency conditions. Unlike earlier registrations containing individual works or stages of the programme, this registration preserves the principal corpus as a unified collection. Its purpose is to establish a stable public record of the programme’s scope, internal development, authorship, and contents as they existed on the registration date. Earlier documentary materials may additionally record the historical development of the underlying ideas; those records should be distinguished from the later complete mathematical formulation. This is a registration of an existing theoretical research corpus. It is not a preregistration of a proposed experiment or empirical study.
This series presents a structured and logically sequential formulation of a discrete informational framework governed by global coherence constraints. Although it originates from the same research program developed in the earlier exploratory preprint series (P-series), the works presented here constitute an autonomous and self-contained series, organized in a progressively axiomatic form and focused on the explicit derivation of the framework’s effective structures. The goal of the construction is to investigate whether structures commonly associated with quantum mechanics, thermodynamics, and geometry may emerge from a discrete relational substrate without being introduced as fundamental postulates. Each article addresses a specific level of the theoretical derivation and forms part of a progressive logical structure based on results established in the preceding works of the series. This article develops the emergence and structural uniqueness of the effective two-field representation arising from the coherent sector identified in Paper 01. The work demonstrates that the coherence-preserving dynamics of the discrete informational framework admit a minimal effective structure based on two coupled components, and that this structure emerges as the unique stable representation compatible with the global coherence constraints. The analysis establishes the conditions under which the two-field sector becomes dynamically unavoidable within the effective description and prepares the mathematical framework developed in Paper 03, where Hilbert-space structure, Schrödinger-type dynamics, and probabilistic emergence are derived. No quantum-mechanical or geometric assumptions are introduced at the foundational level. The purpose of the article is to derive the minimal effective representation required by the internal consistency of the coherent informational dynamics.
This work presents the Action--Phase Protocol, or PAF-I, as a methodological framework to formulate interfaces between distinct physical sectors without resorting to the direct stitching of final equations. The objective is not to propose a final theory of unification, but to build a common layer prior to the final formulations of quantum mechanics, general relativity, electromagnetism, and thermodynamics.The starting point is the identification of the operational phase with the dimensionless action,ϕ=ℏS,so that the action provides the common object and the phase provides the variable upon which the physical sectors act. In this language, the free phase is described byDμ(0)=∂μ,gravity byDμ(g)=∇μ,electromagnetism byDμ(EM)=∂μ−ℏqAμ,and the minimum quantum mechanics by the decompositionψ=Reiϕ,QR=−2mℏ2R∇2R.The central rule of PAF-I is that interfaces between sectors should not be obtained by the direct sum of final equations, but by the composition of the operators that each sector induces on the common phase. The effective dynamics is then derived from a single effective action,δSeff=0.Thus, PAF-I provides a minimum, variational, and non-ad hoc layer to formulate physical interfaces. Its innovation is synthetic and architectural: organizing orthodox tools of theoretical physics into a common language based on action, phase, sectorial operators, and the variational principle.
