Stability Geometry of Branch Structures in Open Quantum Systems. DOI: https://doi.org/10.17605/OSF.IO/RKPTQ. Main paper PDF: tability_Geometry_of_Branch_Structures_in_Open_Quantum_Systems.pdf. Causal–Continuity Stabilization Theory (CCST) characterizes macroscopic causal persistence as a physical stability property of finite substrates, rather than as an ontological feature of the universal wavefunction. In its original formulation, CCST formalized descriptive admissibility: a coarse-grained macroscopic causal history remains well-posed only when thermodynamic dissipation stays below a substrate-dependent bound and when coarse-grained dynamical sensitivity preserves closure. This work extends CCST by addressing a logically distinct question: not only whether a macroscopic description remains admissible within a branch, but whether a branch structure itself can remain dynamically coherent as an organized physical entity under sustained environmental coupling. Although unitary quantum mechanics preserves all components of the global quantum state, organized branch structure may dynamically disperse into microscopic degrees of freedom in open-system dynamics, thereby losing the correlation patterns required for macroscopic organization. We distinguish structural dispersion (loss of branch-level organizational coherence) from Causal Exit (loss of description-level definability on a finite physical substrate), emphasizing that these correspond to stability failures at distinct physical layers and should not be conflated. Using standard open-system effective-action and influence-functional formalisms, we motivate a dynamical weighting over coarse-grained path ensembles: microscopic dynamics induces a non-uniform stability geometry in path space through irreversible dynamical suppression rather than probabilistic selection, without introducing collapse, selection rules, or inter-branch transport. Finally, we introduce a minimal toy model to visualize the qualitative sensitivity of branch-structural persistence under controlled stability thresholds. The model is strictly illustrative and is accompanied by transparent parameter definitions and a reproducible numerical implementation in the appendix.

Causal–Continuity Stabilization Theory (CCST). DOI: https://doi.org/10.17605/OSF.IO/N2SF9. This project develops a geometric and thermodynamic formulation of Causal–Continuity Stabilization Theory (CCST) within the Everettian (Many-Worlds) interpretation of quantum mechanics. While decoherence theory explains the emergence of quasi-classical branches, it does not by itself account for the persistence and stability of a specific first-person causal history. CCST addresses this gap by introducing a stability-based interpretive framework grounded in irreversible thermodynamics, information-processing limits, and dynamical sensitivity. Macroscopic causal histories are modeled as trajectories in a coarse-grained state space equipped with an effective metric that encodes thermodynamic resistance to state transitions. The theory distinguishes ontological branch existence (Born weight) from first-person admissibility, proposing a maximum dissipation bound as a condition for sustained causal continuity. Extensions based on dynamical instability, Lyapunov sensitivity, and geometric deviation are used to explain both gradual (soft) transitions and limiting cases of causal exit without invoking wavefunction collapse, probabilistic selection, or inter-branch dynamics. An interpretive extension further clarifies how first-person experience can be treated as a stability-constrained descriptive projection over physically realized histories, preserving full compatibility with unitary quantum evolution. This repository contains the main manuscript and appendices (A–F), presenting the formal structure, interpretive motivation, and conceptual scope of the theory.
Causal–Continuity Stabilization Theory (CCST): Thermodynamic Stability and Branch-Internal Descriptive Continuity in Everettian Dynamics. DOI: https://doi.org/10.17605/OSF.IO/D6JN7. Causal–Continuity Stabilization Theory (CCST) is an interpretive framework that addresses the persistence of macroscopic descriptive continuity within fully unitary Everettian quantum mechanics. Rather than invoking ontological selection, probabilistic collapse, or inter-branch transition, CCST reframes continuity as a stability property of a finite physical substrate subject to irreversible thermodynamic and dynamical constraints. The theory introduces Thermodynamic Strain as a path-dependent measure of cumulative irreversible burden required to maintain coherent macroscopic descriptive structure across decoherence and branching. CCST remains fully compatible with standard quantum mechanics and preserves the physical reality of all branches, while providing an explicit stability-based criterion for when continuous macroscopic description remains physically well posed.
The persistence of quantum coherence in increasingly massive systems provides one of themost sensitive experimental probes of the transition between microscopic quantum evolutionand macroscopic definiteness. Standard quantum mechanics describes the coherent evolutionof a superposed state with high precision, while the emergence of a single stable outcome isusually accounted for through the measurement postulate or through environmental decoherence.Here we formulate a wavefunction admissibility criterion in which coherent unitary evolutionis sustained only while the branch-dependent, coarse-grained energy variance remains below auniversal dimensionless threshold.The characteristic scales entering the criterion are fixed by a QCD chiral scale and a topologicalclosure factor, rather than by an independently fitted localization length or empirical collapserate. The resulting framework defines a dimensionless branch-burden functional B[Ψ] and aLindblad-type coarse-grained energy-density channel governing the exponential reduction ofbranch coherences. The objective-collapse regime is reached whenB[Ψ] ≥ 2π,leading, for center-of-mass superpositions, to a collapse time scaling asτcmcoll ∝ M−1∆X−2F−1net.We compare the criterion with existing matter-wave interference data, including C70 fullerenes,complex organic molecules, molecular libraries above 104 amu, and oligoporphyrin compoundsexceeding 25kDa. The observed survival of interference in these experiments is consistent with thecoherent-admissible regime because the interferometers isolate the center-of-mass wavefunctionwithout generating irreversible multi-degree-of-freedom record amplification. The frameworktherefore predicts not a simple mass cutoff, but a residual non-environmental visibility losscontrolled by the combined scalingΓresidual ∝ M∆X2Fnet,after conventional environmental decoherence has been independently bounded
This accepted manuscript is structurally governed by THE META-INDEX (Zenodo DOI: 10.5281/zenodo.18169167) Quantum theory achieves unparalleled empirical success, yet it remains ontologically incomplete with respect to the nature of transitions between physical states. While quantum states are rigorously defined, the process by which a system moves from a potential state to a realized state is typically treated as instantaneous, probabilistic, or measurement-dependent, leaving the transition itself conceptually unexamined. This structural omission underlies several persistent foundational problems, including the measurement problem and the ambiguous status of probability. In this work, quantum behavior is reinterpreted not as an intrinsic property of discrete entities, but as the manifestation of threshold organization governing stable transitions between states. To formalize this perspective, the concept of an Organizational Field (OF) is introduced. The Organizational Field is defined as a topological–temporal regulatory structure that constrains admissible transitions without functioning as a force, energy carrier, or particle field. Within this framework, quantization emerges as a consequence of stability regulation during transitions rather than fundamental discreteness. The fine-structure constant α is accordingly reinterpreted not as a fundamental coupling parameter, but as the stability-band signature of the Organizational Field as projected onto electromagnetic processes. This interpretation accounts for the dimensionless character of α, its small but nonzero value, and its universality across physical scales, without attempting to derive its numerical magnitude. A conceptual distinction is drawn between π as a constant of static geometric form and α as a constant of dynamic transition stability. The framework yields falsifiable predictions, including the existence of micro-band structures in transition statistics and context-sensitive deviations under extreme conditions. The proposed model offers a structural completion of quantum theory by introducing an explicit ontology of transition grounded in threshold organization
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.
What are the physical conditions required for agency?Recent work has rigorously shown that purely unitary, coherence-preserving quantum dynamics are insufficient to support deliberation, comparison of counterfactual actions, and reliable action selection. These results establish a genuine no-go theorem for agency in a strictly quantum-coherent regime.This paper provides a structural completion of that no-go result. Rather than challenging its correctness, the analysis identifies the underlying assumption on which it rests: that unitarity alone is sufficient as an admissibility criterion for decision endpoints. We show that this assumption is incomplete.Working within the Tier-0 closure framework, physical lawfulness is characterized by closure-stable fixed points selected by structural constraints rather than by unconstrained dynamical evolution. Within this framework, coherent quantum states may function as intermediate computational or representational states but are excluded as lawful endpoints for records, decisions, and control.Applying closure stability to quantum systems yields a classical decision subspace without introducing new dynamics, observer-dependent postulates, or interpretation-specific assumptions. The paper further shows that agency requires a closure-stable internal selection process capable of consistent expected-utility comparison. Imposing closure compatibility rigidly fixes the standard quadratic Born probability rule as the only weighting compatible with stability, representation-independence, and admissibility-preserving re-expression.Together, these results integrate agency into the same structural framework that accounts for quantum measurement and probability. The absence of agency in purely quantum-coherent models is shown to reflect an under-constrained admissibility regime rather than a fundamental limitation of quantum theory. Lawful agency emerges as a closure-stable property of coupled agent–world dynamics, fully consistent with standard quantum mechanics.This work clarifies the physical limits of purely quantum models of decision, sharpens existing no-go arguments, and provides a mathematically explicit foundation for agency grounded in structural admissibility rather than interpretation. https://doi.org/10.5281/zenodo.18028427
