This record contains the archived materials for Simulation B of the finite-barrier electron double-slit study conducted entirely within standard nonrelativistic quantum mechanics.The deposit includes four distinct records: the post-exchange protocol reconstruction, the frozen Simulation B outcome package dated 24 September 2026, the final numerical closure record, and a separately labelled post-exchange reconstruction of the setup-specific ~0.13 numerical scale using only values preserved in the frozen outcome record.The historical raw solver archive for Simulation B was not preserved. Accordingly, the protocol reconstruction and the ~0.13 reconstruction are explicitly identified as post-exchange records and are not presented as original preregistration artifacts or as reproductions of the historical solver.The frozen outcome package remains unchanged and serves as the primary provenance commitment for Simulation B.Simulation B provides an independent qualitative consistency record for the study, but it is not treated as a point-by-point numerical replication of Simulation A because the geometries, controls, detector coordinates, and normalization differ.The associated joint numerical record for Simulation A, including the frozen technical package, detector-position supplement, and wall-height scaling supplement, is available at:DOI: 10.17605/OSF.IO/V65H3Associated manuscript:Finite-Barrier Double-Slit Scattering in Standard Quantum Mechanics: Numerical Separation of Through-Thickness and Finite-Wall ResponsesAuthors: Ali Alhawarat and Pasquale Camelia.

A frozen numerical record of a two-dimensional electron double slit in which the idealized impenetrable wall is replaced by a barrier of finite height and finite thickness, and the response is measured against a finite low-transmission control rather than against an infinite wall. Three artifacts. The primary record contains a preregistration of five cases, an independent split-operator solver, the closure evidence and a gate ledger; it was cryptographically committed before a blind exchange with an independent worker who had frozen his own calculation. A detector-position supplement varies only the plane at which the current is recorded, 1–14 nm, and identifies which planes are physically usable rather than forcing them. A wall-height record varies only the barrier height, 2.35–24 eV on both sides of the control, and both thicknesses. What the records establish: the finite-minus-control response separates into a through-thickness term, calibrated independently by the no-slit geometry, and a face and edge term that survives when the thickness kills tunnelling; a hard spatial partition into "material" and "aperture" contributions is not well defined, since shifting the mask by one or two grid cells reverses the sign of the attributed bulk contribution; the residual vanishes only when the two walls are identical and reverses sign when the test wall is the harder one, so it is the difference between two standard responses and not a property of one wall; and its form is one scalar function of the wall height times one geometry constant. What they do not establish, and prove they cannot establish in this geometry: which property of the wall carries that function, since a null regressor with no derivation behind it fits equally well and the measurement that would separate the two is smaller than the numerical systematics. No additional quantum path, no Born-rule violation and no physics beyond the time-dependent Schrödinger equation is claimed or supported. Withdrawn constructions, corrections and errata are retained in the records rather than removed. Each archive carries a manifest, a verifier that re-derives its summary from the raw output and rebuilds its report byte-identically, and a set of mutations that must each be caught — six, five and seven negative controls respectively. The two supplements reproduce values of the primary record's gate ledger bit for bit. Every claim carries its register: exact result, computed here, conditional, constitutive, open, or prediction.
This work studies a finite-potential, finite-thickness electron double slit entirely within the time-dependent Schrödinger equation. Three main findings survive numerical and adversarial checks. First, a sharp real-space partition between material and aperture contributions is not unique: small shifts of the partition can alter the assigned bulk contribution and reverse its sign. Second, thickness scans separate a through-thickness term, independently calibrated in a no-slit geometry, from a finite-wall residual that remains when direct barrier transmission becomes very small. Third, varying the wall height through a finite 8 eV control drives the finite-minus-control residual through zero and reverses its sign. The wall-height dependence transports across thickness with one fitted geometry constant, while the physical carrier of that dependence remains unresolved. No result requires an additional quantum path, a Born-rule violation, or dynamics beyond standard quantum mechanics.
A source-inclusive coherence observable is useful only when its measurement resources are admitted. This preprint constructs a bounded local reader for the conserved exchange observable of a specified finite quantum-record apparatus. A degree-three graph uses one independently prepared probe, twenty relays with arbitrary joint states, and finite-duration two-register extraction and full-SWAP interactions. The original apparatus Hamiltonian and an independently added archive-gated process remain active throughout their respective implementations. A prefix-dependent control-frame comparison, symmetry-resolved effect estimate, and explicit gain, phase and finite-slew waveform bounds yield a sufficient response separation greater than 0.005139889 for the stated fixed, fully accessible sixteen-position source and remaining response-error budgets. This is a conditional mathematical result, not measured hardware calibration, a partial-source-access theorem, or a unique diagnosis or derivation of fundamental collapse. The package contains the main manuscript, technical supplement, editable LaTeX, direct numerical reproduction sources, and accepted returned Mac evidence for 56 paper-specific supporting Lean declarations. That subset verifies selected algebra, scalar inequalities and the actual-constant numerical expression; it does not formalize the full physical/continuous-time theorem end-to-end. Separate-session AI review, numerical reproduction and returned kernel evidence are distinguished. Author-owned manuscripts, documentation and mathematical data are CC BY 4.0; newly authored numerical and Lean software is MIT. Predecessor and third-party notices remain unchanged; the reproduction package contains the licence map. No external funding; no competing interests declared.

BCRD (boundary-complete relational dynamics) is a finite quantum-spin research programme studying whether relationally accessible records inside a finite closed system can support their own effective dynamics. This archival v0.1 release records the reviewed programme frontier as of 14 September 2026 using a workflow that separates construction, hostile review, reconciliation, and prospective preregistration.The reviewed finite results include a sufficient finite-range mediator repair of an earlier locality failure; representative-specific native transport distinct from a Feynman-cursor control; predictive records that do not automatically self-update; exact reconstructive closure from one-known-spin erasure correction; approximate common-CPTP-map compatibility for six exposed N=8 transitions of a proper coarse record; and finite process results separating one-time coarse channels from honest semigroup dynamics. The first legal N=8 causal-break memory test remains unresolved above its apparatus floor.A direct recoupling lane establishes a model-specific adjacent-pair Racah 6j² transition probability in a historically declared pair-Lüders interface. This is explicitly not claimed to be a coherent Racah amplitude, physical F-move, pentagon/Pachner dynamics, Ponzano-Regge/Regge sector, continuum gravity, or quantum gravity. A phase-sensitive N=4 recoupling study has been prospectively frozen but no outcome from that study is included in v0.1.This deposit is intended as a durable public priority and provenance record, including explicit negative results and nonclaims. It is not a final journal manuscript and does not claim that BCRD has established quantum gravity.

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.

The 39 supporting declarations are partially formalized; eleven recorded type excerpts contain printing elisions.
