This artifact applies a single structural constraint across several canonical problems in physics and cosmology: history is not free. Using Structural Flow as a minimal structural grammar, the paper examines double-slit observation, entanglement, wavefunction collapse, photon propagation, dark matter, and nothingness by asking where physical explanation quietly assumes costless persistence, costless memory, or costless integration. The goal is not to propose mechanisms or compete with empirical models, but to record what follows when those assumptions are withdrawn. This version is preserved as a live origin-layer bridge in the physics program. Its central accounting move remains active, while some downstream questions—most notably dark matter—have since been sharpened differently in later work. The artifact is therefore preserved for continuity and public legibility rather than presented as the final canonical formulation of every physics-facing claim it touches.

What if dark energy, classical selection, and dark matter are not independent ingredients of the Universe, but three temporal regimes of a single informational process that generates physical reality itself? In the broader Cosmology of Time (CT), the Future (Dark Energy) is proposed as the domain of open possibilities, the Present (classical selection) as the domain of physical actualization, and the Past (Dark Matter) as the accumulated regime of sedimented records that can actively constrain what happens next. In its full cosmological form, this triadic grammar is associated with the large-scale structure of reality: Future as possibility, Present as actualization, and Past as historical constraint. This work does not yet test the cosmological model directly. Instead, it presents a minimal causal realization of its underlying grammar. Using a collision model with memory, this toy program asks whether the core internal logic of the CT framework can be instantiated in a minimal, explicit, and computationally inspectable system. The result is a formal exercise in which: the Future appears as accessible possibility space, the Present appears as selection plus recording, the Past appears as sedimented record, and accumulated memory acts back on the system as an active constraint on subsequent evolution. The model also isolates a nontrivial distinction between decoherence and registration, and exhibits a measurable compression of accessible future under historical accumulation. Most importantly, the program succeeds in showing that the internal grammar of the CT framework admits a coherent minimal causal realization: Future, Present, Past, sedimented record, and active memory can all be instantiated within a single causal architecture, while the separation between decoherence and registration and the historical compression of accessible future emerge as nontrivial formal results. This is not yet a predictive cosmological theory. It is the first minimal formal test of whether the internal grammar of the Cosmology of Time can be realized as a coherent causal program. The deposit includes the main preprint, supplementary technical documentation, and a code appendix with the available source implementations.
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 paper presents a philosophical analysis of quantum mechanics, the measurement problem, the observer problem, decoherence, and quantum interpretation. It argues that the central difficulty in quantum mechanics is not only technical but interpretive: the theory has extraordinary predictive power without a single settled account of what is happening physically or ontologically. The paper frames this as an answerability problem, asking how interpretations should be judged when formal success outruns explanatory closure. It separates several meanings of observation—interaction, coupling, record formation, information update, and conscious awareness—and shows how collapsing these layers creates confusion in both physics and philosophy. It then compares major interpretations including Copenhagen, Many-Worlds, Bohmian mechanics, objective collapse, QBism, relational quantum mechanics, and consistent histories, treating them as different ways of stabilizing explanatory burden around an underconstrained formal core. The paper also argues that decoherence is crucial for understanding record stability and the appearance of classicality, but does not by itself solve the single-outcome problem. Overall, the paper offers a clear framework for thinking about quantum foundations, scientific explanation, ontology, observation, and philosophy of science without overstating what current theory can responsibly claim.
This is the tenth paper of a series that redescribes physical reality as a causally consistent history of information updates, and the first panel of its second triptych - observer, then probability and typicality, then epistemic trust - ordered by dependence, since one cannot weigh observers before saying what counts as one. The ninth paper reasoned about observer typicality, Boltzmann brains, and a cosmological measure without ever saying, independently, what an observer physically is. This paper retires that undefined term. It declines the framing "for whom does a record exist" - in this framework records exist, and can even be public, with no one reading them - and asks instead for what kind of operationally individuated physical subsystem records can be acquired, integrated, internally decoded, and made causally relevant to later processing. The thin "any interacting system" notion of relational quantum mechanics is too thin for this epistemic and cosmological role; it does not by itself specify what physical structure carries records and licenses diachronic identification across interactions, and the paper develops a specific physical implementation layer, centred on endogenous accessibility and record-conditioned causal use, that the thin observer notion does not itself specify. The answer is two-layered. A candidate observer is individuated relative to a boundary, domain, timescale, tolerance vector, and endogenous operations-and-resources profile, under non-arbitrariness conditions permitting nested, overlapping, and distributed individuations - flagged as an explicit, unresolved observer-grain problem. Against a graded hierarchy of interactor, detector, recorder, observer, and agent, the paper separates an observer architecture, which implements four capacities, from an observation episode, which exercises them. Its sharpest commitment is endogenous accessibility, or self-legibility: a physically implemented internal decoding channel under the system's own resources - not a decoder in the theorist's description and not an inner reader. A companion two-relation account characterizes observer-lineage continuation across relational time, distinguishing architectural from epistemic continuation rather than asserting identity. The paper makes no independent empirical prediction; it derives neither quantum theory, the Born rule, nor a measure over observers, and offers no theory of consciousness.
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. 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. The core derivation runs Papers 0–11; the extension papers carry the individual sectors. Each paper's main text and Technical Supplement is deposited separately, and every quantitative claim traces to a named, executable check in the public theorem bank (over 3,800 bank-registered theorems across roughly 450 modules, 48 quantitative predictions).

This record provides the overview and organizing entry point for a research program examining several long-standing “unsolved problems” in fundamental physics. Rather than proposing new particles, interactions, or dynamical laws, this series demonstrates that a number of canonical problems arise from a shared category error. Under finite resolution and internal description, these problems are shown to dissolve structurally and independently. The series establishes a common set of minimal premises—finite resolution, irreversible internal projection, and non-privileged description—and applies them uniformly to multiple domains. Each associated volume isolates a single problem and demonstrates its elimination without cross-dependence on other topics. The following volumes form part of this research program and are linked as related works: Vacuum Energy Hierarchy Problem Quantum Gravity Arrow of Time Dark Matter Each volume is designed as an entry-point paper and may be read independently. Detailed mathematical, conceptual, and phenomenological developments are archived in the cited records under persistent identifiers. Disagreement with the conclusions of this program requires explicit rejection of one or more stated premises. This research program consists of the following volumes: Vol.1 — Quantum Measurement (foundational layer)Vol.2 — Hierarchy ProblemVol.3 — Vacuum EnergyVol.4 — Quantum GravityVol.5 — Arrow of TimeVol.6 — Dark Matter Each volume is archived as an independent record with its own DOI and can be accessed via the related works listed above.
