Summary: “Entanglement Shapes Reality: Public Facts from Redundant Records” introduces a preregistered, decoder-agnostic commit time t_commit^(I) for when classical objectivity emerges in open quantum systems. Using only unitary quantum mechanics and standard information-theoretic bounds (Fawzi–Renner recovery floors and Fano/Bhattacharyya accuracy caps), it provides falsifiable predictions for when redundant environmental records guarantee reliable classical inference. The framework requires no additional ontological postulates and is stated as preregistered decision rules with explicit falsifiers. Key scaling:t_commit^(I) = I_star / (m0 * kappa * Gamma) ~ (m0 * kappa * Gamma)^(-1).We test this via independent sweeps of m0, kappa, and Gamma.

This paper is the third in a sequence developing an interpretive framework that redescribes physical reality as a causally consistent history of information updates rather than as a collection of objects independently existing within spacetime. The parent framework, The Universe as a Consistency-Constrained Information History, argued that the constitutive core of auditability is not a bureaucratic log but record definiteness: the existence of stable, reproducible, path-independent commitments. The companion paper, Consistency Without a Global Clock, refined observation into a three-stage process—interaction, commitment, and finality—and identified finality with redundant, environmentally distributed, and independently recoverable recording. The present paper joins these two threads. Its question is narrow and structural. Decoherence and environment-induced superselection explain commitment: why local interference becomes practically irreversible and why stable pointer states emerge. They do not, by themselves, explain public finality: why a committed fact can be confirmed by many mutually independent parties, non-disturbingly and repeatably, as the same fact. The organizing distinction of the paper is therefore decoherence ≠ finality. A private microscopic correlation can be committed locally at low redundancy, yet fail to be a publicly shared fact. What such public finality additionally requires is the object of the analysis. The argument runs through three steps that lean on established results rather than new mechanisms. First, the no-broadcasting theorem implies that noncommuting quantum information cannot be distributed as-is to many parties; consequently, any value that many independent accessors can recover non-disturbingly must be effectively classical pointer information. Second, spectrum broadcast structure supplies the canonical form of such redundant environmental encoding, and quantum Darwinism supplies its dynamical mechanism. Third, if public finality in a given context requires m mutually independent accessors, acting on disjoint environmental fragments, to recover a committed fact within an information deficit δ, then the available environmental redundancy must satisfy a demand-side lower bound Rδ ≥ m. This is not a prediction of how much redundancy the world realizes; the realized amount is supplied by physics. It is a statement about the minimum redundancy a record must carry to count as publicly final. The thesis is summarized as an Auditability–Redundancy Principle: redundancy is not an accidental ornament of objectivity; it is the physical form that decentralized auditability must take. The paper supplies no new mechanism for redundancy, does not derive the Born rule, does not solve the measurement problem, and does not claim that redundancy is universal. In no-collapse readings, the facts discussed here are branch-relative or decoherent-history-relative. The status of the paper is L2, a necessity/convergence claim, while its formal engine rests on established L1 results.
Submission Candidate 4 of the manuscript “Stable Partial Objectivity without a Global Classical Table: Contextual Obstruction, Relational Facts, and Redundant Environmental Records,” prepared for submission to Foundations of Physics. The paper studies whether stable, redundantly accessible environmental records of a selected observable can coexist with contextual obstruction in a broader measurement scenario. In an analytically controlled finite-dimensional qutrit KCBS model, a single joint branch state generates both reduced-system contextual decay and quantum-fragment distinguishability. The analysis establishes a nontrivial parameter interval in which decoder-certified redundancy is maximal while the incompatible KCBS empirical model retains nonzero contextual fraction, and it quantifies the associated frontier between recordable pointer entropy and retained contextual obstruction.

This paper is the twenty-ninth in a sequence developing an interpretive framework that redescribes physical reality as a causally consistent history of information updates rather than as a collection of objects independently existing within spacetime. It returns the series to its physics-of-records basement after a long ascent through semantics, epistemology, agency, and the constitutive foundations of normative standing. Its question is narrow and physical: when does a quantum record that has been redundantly encoded in the environment count as a warranted public record — a record fit to be treated as shared, independently checkable, finality-graded evidence? Two prior papers already settled what this paper deliberately does not re-derive. Paper 3 established the world-side form of public finality for quantum records: a publicly final fact must be effectively classical pointer information, redundantly encoded across many disjoint environmental fragments, satisfying a demand-side redundancy bound, drawing on no-broadcasting, spectrum broadcast structure, and quantum Darwinism. Paper 8 separated, inside quantum mechanics, the temporal address of a record from its formation. The present paper adds the type-separation those two leave open: relational temporal address is not physical publicity capacity, and physical publicity capacity is not warranted public standing. The central result is a separation, not a new piece of physics. On the framework's declared anti-luck conception of warrant, meeting Paper 3's redundancy bound is necessary but not sufficient for warranted public standing. This is made precise in two steps. Unconditionally, two histories are constructed that realize the identical audited reduced state on the system and its environmental fragments — and, where stability is at issue, the identical audited reduced process over an audit interval — hence the identical spectrum-broadcast structure, redundancy, fidelity, and accessibility, so that no functional of the audited state alone can tell them apart — yet whose target-relative provenance profiles differ: in one, the fragments branch after the recorded event into mutually independent system–environment interactions; in the other, they pass after that event through an additional common source. It follows that provenance admissibility is not a functional of the audited quantum state. Conditionally, under a declared anti-luck calibration in which the second history's additional common bottleneck, selective retention, and closed challenge path constitute a defeater, the two histories receive different warranted-public-standing profiles. So warranted public standing tracks provenance, not redundancy alone — and not by stipulation, but because a recovery whose apparent independent agreement is an artifact of a single source is, in the series' anti-luck sense, unwarranted. The quantum publicity ceiling itself — that only effectively commuting content can be exactly public — is imported as background, not claimed as novel. The paper further shows that no quantum record certifies its own warranted public standing from inside, and that an adequate relational temporal address does not by itself confer public standing. All of this holds without a Global Bookkeeper: no physically privileged subsystem inside a consistency-constrained quantum information history supplies, primitively and globally, a non-contextual valuation, a privileged simultaneity, a canonical subsystem cut, a unique classical history, a self-certifying finality, or a global reference frame.

This paper is the seventh in a sequence developing an interpretive framework that redescribes physical reality as a causally consistent history of information updates rather than as a collection of objects independently existing within spacetime. Two prior results set up its question. The third paper (Uchida, 2026c) characterized public finality—recoverability of a committed fact by many mutually independent accessors, non-disturbingly and repeatably—as a broadcast redundancy: an effectively classical pointer value proliferated across many disjoint environmental fragments, approximately in the form of spectrum broadcast structure. The fourth paper (Uchida, 2026d) read the evaporating black hole as the regime in which a committed interior record crosses, at the Page time, from hidden to recoverable encoding, reconstructible from the radiation through entanglement-wedge reconstruction; and the parent framework (Uchida, 2026a, §10) had flagged holographic quantum error correction as a place its language of protected, redundantly encoded, locally recoverable records might find content. The present paper makes that content precise as a structure theory of recoverable records, kept separate from any claim of new physics or any suggestion that the framework derives the underlying results. The central claim is conditional and structural. The framework does not claim that every recoverable piece of information is a code, that the universe is literally a quantum error-correcting code, or that AdS/CFT describes our universe. It claims that when information qualifies as an erasure-recoverable record because an encoding preserves a logical degree of freedom—or a logical operator algebra—against a specified family of physical erasures, then that recoverability is formalized as an exact or approximate quantum error-correcting structure, in which each correctable erasure leaves an authorized complementary region supporting a recovery map. That formalization is itself an established mathematical classification; the paper's interpretive contribution is to read the series' recoverable record through it, and to set it against a second, distinct architecture. Broadcast redundancy makes the same effectively classical value legible from many disjoint fragments; erasure-correcting redundancy protects noncommuting logical quantum information by keeping each correctable erased region ignorant of—approximately private with respect to—the protected logical content, while suitable remaining regions recover it. The formal engine of this distinction is the duality between correctability and privacy (the information–disturbance tradeoff), not the no-cloning theorem; no-cloning, with the access structure of quantum secret sharing, survives as the reason independently usable recovery regions for arbitrary unknown logical quantum information must overlap. Three commitments keep the reading honest. First, it separates three senses of "record"—protected logical quantum information, a committed classical record, and a publicly final record—and insists that recovery or decoding restores access to logical quantum information but does not, by itself, commit a classical value; commitment additionally requires measurement, pointer imprinting, decoherence, and stabilization (Uchida, 2026f), and public finality a still later broadcast. Second, holographic quantum error correction is offered as the sharpest worked model of the distinction, with exactly solvable tensor-network toy codes (exact within the model) kept distinct from realistic semiclassical holographic reconstruction beyond those limits (generally treated as approximate), and both from the further question of state-dependence. Third, code-recoverability does not by itself imply public finality: protected quantum information can be recoverable from authorized regions while remaining non-public. The framework relabels code structure as the architecture of recoverability and derives none of it, making no independent empirical prediction. Its disciplined thesis is that codes protect recovery; broadcasts create publicity—different architectures that a single physical history may nonetheless realize in sequence.
This record archives version v1.3 of the manuscript “Unified Residual Classicality Criterion for the Quantum-to-Classical Transition” and its full reproducibility package. This version is the repository companion to the journal-submission version prepared for Quantum Studies: Mathematics and Foundations. It includes the main manuscript, supplementary mathematical notes, supplementary validation report, figure source archive, LaTeX/source archive, benchmark CSV files, Python scripts, manifest files, citation metadata, license file, checksums, and author declarations. The work proposes a falsifiable, comparator-dependent residual-vector criterion for assessing quantum-to-classical behaviour. Classicality is certified only when predeclared residual channels — dynamical, semiclassical, operational, coarse-graining, and open-system — simultaneously pass their declared tolerances for a specified comparator, observable class, resolution, norm, and finite time interval. The work does not claim a universal solution to the measurement problem or a universal proof of quantum-to-classical emergence; it provides a finite-time certification framework with sufficient error-control conditions and controlled benchmark validation.

This manuscript presents a methods-forward, operational protocol for evaluating whether any structured dependence remains in quantum-computing measurement records after explicit modeling of standard quantum and device-level mechanisms. Classical definiteness is defined at the record layer, and pre-record states are treated as predictive descriptions rather than as classical outcome facts. Within this operational stance, the protocol converts questions about outcome status and record formation into a falsifiable test program grounded in preregistered analysis rules and standard measurement telemetry. A locked null-model family is specified in advance, incorporating standard quantum dynamics together with documented device-level mechanisms including drift, correlated and non-Markovian noise, crosstalk proxies, and leakage indicators. The framework provides operational definitions, a conservative postulate set, preregistered endpoints, residual-adjudication criteria, negative controls, a fixed windowing discipline, and a bound-first reporting standard designed to yield informative constraints under null results. Any candidate contribution beyond the declared null family must appear as structured, reproducible residual dependence that survives the locked null family and the full residual-filter sequence. Version 4.4 refines the protocol specification, clarifies evidentiary boundaries, and strengthens the integration of the synthetic demonstration. The manuscript includes a fully specified classical simulation that executes the decision pipeline under controlled conditions. The synthetic study illustrates how the protocol classifies a bounded-null case, a measured-artifact case, a partial-artifact/unresolved-covariate case, an injected structured-residual case, and a failed-topology case. This demonstration establishes computational executability of the protocol and clarifies the behavior of the decision tree, but it does not constitute empirical evidence for any physical mechanism. Because the protocol relies only on standard measurement telemetry and preregistered analysis rules, it is directly implementable across contemporary quantum-computing platforms and does not depend on any single dataset, backend, or hardware realization. The manuscript is a specification paper: it defines a reproducible evidentiary framework for record-level claims, while large-scale empirical implementation, hardware benchmarking, and cross-platform replication remain subsequent studies.
