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 archive contains the manuscript PDF and LaTeX source, vector and raster figures, canonical Python scripts, generated JSON data, model and validation documentation, cryptographic checksums, and a portable Git bundle.

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.

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.

Quantum Darwinism explains effective classical objectivity through the selective proliferation of information about preferred quantum states into multiple environmental fragments. Its mature formulations operate within quantum theory, using a system-environment decomposition, decoherence or einselection, and information-theoretic or broadcast-structure criteria for redundant accessibility.This paper asks an upstream question from Registration Theory (RT): what makes a physical distinction a record before that record is described as information available to an observer? Canonical RT answers that retained registration is persistent organization constraining later evolution, that a distinction becomes a physical record only when it remains consequential, and that persistent physical organization is prior to information extracted from it.The paper assembles a theorem-backed finite-model chain now available in the RT corpus. Canonical ACRF dynamics supplies write-retain-read consequential history. The exact finite-amplitude ACRF-4 quotient identifies a nine-dimensional host-host-boundary state. The certified consequence-minimality theorem (DOI 10.6084/m9.figshare.34063464) shows that the retained relational boundary contributes irreducible future-consequence directions. The spectrum-preserving ACRF-8 redundant-record theorem (DOI 10.6084/m9.figshare.34063500) then proves an explicit local witness in which one quotient-valid source distinction is written into two disjoint retained fragments that are locally recoverable, counterfactually separable, and independently readable, giving RRT(q)≥2 under the stated criteria.The resulting distinction from Quantum Darwinism is precise but bounded. RT recordhood is consequence-based, while Darwinian objectivity is an accessibility-and-redundancy criterion formulated within quantum theory. The ACRF witness demonstrates redundant retained record formation without assuming Hilbert space, density operators, mutual information, decoherence, einselection, Born probabilities, or an observer-defined environment. Therefore, multiple persistent records of one distinction are not definitionally identical to Quantum-Darwinian redundancy.The paper does not claim that Quantum Darwinism is false or that RT has derived quantum mechanics, decoherence, Born probabilities, a mutual-information redundancy plateau, or macroscopic objectivity. Instead, it proposes a disciplined hierarchy: consequential distinction → retention → persistent record → branching → redundant retained records → redundant accessibility → environmental objectivity. The final two steps remain open in RT. A future bridge must dynamically select and scale multi-host redundancy and map consequence-bearing RT records into quantum environmental fragments that satisfy decoherence and strong objectivity conditions.
A durable quantum record, the location of its coherence, and a uniquely actual outcome are different physical questions. We study their separation in a supplied finite-dimensional quantum theory. An explicit, time-independent apparatus couples a system–detector encoding to a controller, a distinct archive, and a finite returning source. A conditional energy penalty suppresses release of the original record without deleting its return coupling. An invariant reduction and a one-sided spectral-gap estimate yield a certified interval with archive occupation above 0.98438, controller-latched occupation above 0.99161, and filled-but-unlatched weight below 2.402 × 10^-7 in one stated design. The same record statistics admit different source-label overlaps and hence different coherence on a specified retained boundary. A conserved product of complementary exchanges accesses that coherence when the finite source is included. Given a calibrated multiregister reader, its finite-duration response separates the coherent apparatus from an independently added archive-gated reduction law, with the added process left active during readout. A conservative example retains a response gap above 0.01717 after separately stipulated one-percent error allowances. The contribution is the finite construction and its quantitative retention, access, and readout interfaces. Quantum carriers, Hamiltonian couplings, trace readout, source preparation, and the reader are supplied; local reader synthesis, empirical calibration, absolute rate selection, and unique-event actualization are not established.

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.
What does a rising redundancy curve actually prove? This deposit accompanies “Raw-Fragment Benchmarking for Redundancy Tests in Quantum Darwinism and Spectrum Broadcast Structure,” a paper built around a practical but often hidden problem in tests of quantum objectivity. Aggregate mutual-information curves can show that information grows with fragment size, but they do not reveal whether independent fragments really carry accessible, mutually consistent records of the same pointer variable. The missing evidence lives one level lower: in the raw, shot-indexed fragment records. The paper turns that gap into a reproducible benchmark. Starting from a fixed synthetic binary pointer-copy model with 100,000 shots and eight heterogeneous fragments, it asks what a raw-fragment evidence package should expose before redundancy, consensus, or Spectrum Broadcast Structure-style objectivity is inferred. The analysis enumerates all fragment subsets, separates mean-over-subsets and all-subsets threshold crossings, measures fragment disagreement, reproduces analytic binary-channel threshold maps, applies coupling-breaking negative controls, and stress-tests the result against hidden common-mode correlated errors. The resulting picture is sharper than an aggregate curve. In the baseline model, the 0.9 information-fraction threshold is crossed at subset size m=3 under the mean criterion, but only at m=4 under the stricter all-subsets criterion. Negative controls remain below threshold, while a hidden common-mode flip exposes the main fragility axis: many agreeing fragments can still fail as evidence for independent records if they share the same unobserved error source. The attached PDF gives the manuscript-level argument and results. The arXiv source package supports manuscript reproduction, and the ancillary benchmark archive contains the synthetic raw-shot data, subset diagnostics, disagreement tables, threshold maps, negative-control outputs, common-mode sensitivity maps, figures, scripts, manifests, and checksums. The scope is deliberately bounded. This is a synthetic/model-level benchmark and reproducibility package, not an experimental claim that Quantum Darwinism or Spectrum Broadcast Structure objectivity has been observed. Its purpose is to make explicit what future experimental raw-fragment evidence should provide before a plotted redundancy signature is treated as a claim of objective, independently accessible records.
