This theoretical note develops an event-admissibility criterion for photon detection within Constrained Null Geometry (CNG). The central distinction is between the Born weight of a decohered channel and the geometric admissibility of that channel as a realized event. In the standard post-decoherence reading, diagonal channels are normally treated as directly eligible event outcomes. This paper inserts an additional CNG closure layer: a null channel can become a detected photon event only if its transported boundary data closes into a timelike boundary record. When all decohered channels are closure-admissible, the ordinary Born rule is recovered. When some channels fail closure, the physical event probabilities are restricted to, or dynamically transported into, the closure-admissible event subspace. The note formulates both a conditional projection rule and a stronger trace-preserving closure-flow realization. The latter gives a possible experimental discriminator: weak-channel dominance without coherent interference and without proportional loss of total event rate. This distinguishes CNG event closure from ordinary interference, optical filtering, detector loss, or post-selection. The paper is theoretical. No laboratory claim is made. Its purpose is to formulate a precise post-decoherence event-closure criterion, derive the corresponding mathematical consequences, and identify a measurable discriminator for future optical tests. The accompanying reproducibility supplement contains Python scripts, generated data, summaries, and figures for the numerical closure-discriminator scans used in the paper.

This paper gives a precise mathematical form to intrinsic quantum event closure at the qubit level. It distinguishes a complete event, which carries one definite material record, from an ensemble description in which the individual complete-event coordinate is unspecified. The paper first proves that a small set of standard operational requirements uniquely fixes the two-outcome qubit probability law, independently of any particular geometric representation. It then constructs an explicit deterministic realization that applies to both pure and mixed states and reproduces the standard quantum probabilities exactly. A central result is that substantially different geometric partitions of the event space can generate the same complete set of observable probabilities. The paper therefore identifies the invariant physical content not with any single diagram, boundary, or geometric partition, but with the preserved mapping from complete events to material records and the measure carried into those records. A general representation-invariance result formalizes this conclusion. The paper also separates Hamiltonian state evolution from material event closure, assigning them distinct mathematical and ontological roles. The work does not claim a universal solution to quantum measurement, a derivation of the event space from a deeper theory, or an extension to entangled and higher-dimensional systems. It establishes an exact qubit-level framework in which individual events close deterministically while ensemble statistics reproduce the Born rule.

Single-photon interference and delayed-choice experiments resist any account that treats the photon as a localized object carrying a private classical history. We propose the boundary-defined null connection (BDNC) view: a photon event is a null spacetime relation completed jointly by emission and absorption, with observable behavior fixed by the complete experimental boundary. The null-relation primitive itself is not novel — it appears in Kastner's relativistic transactional interpretation, Sorkin's causal-set null-link program, and the all-at-once / TSVF / Fixed Point Formulation literature. The contribution is unifying language: BDNC compresses these into a single vocabulary and identifies one operational criterion — whether the boundary modifies only post-selected correlations or also unsorted marginals. The latter case, parameterized by a generic future-state weighting ansatz, amounts to no-signaling violation rather than a BDNC-specific law; we outline two marginal-stability protocols and one weak-measurement consistency check that would constrain such deviations. The principal claim is therefore a unifying diagnostic, not a new falsifiable prediction: any predictive version must derive a BDNC-specific functional form for the future-state weighting. §11 sketches Twistor-Boundary Phase Geometry as a possible mathematical language for the framework, with the explicit caveat that minimal TBPG is empirically equivalent to standard twistor / gauge / QED. The paper is paired with a companion predictive extension: "Null-Boundary Response: A No-Signaling-Preserving Predictive Extension of the Boundary-Defined Null Connection Framework" (Zhang 2026, TBD Zenodo DOI), which proposes a candidate predictive law that produces a no-signaling-preserving channel-antisymmetric correction to coincidence statistics, with a six-feature experimental fingerprint testable in a phase-scanned delayed-choice quantum eraser.
This work separates several physical and theoretical burdens that are often grouped together under “the quantum measurement problem” and develops an experimentally answerable test of one of them: outcome-conditioned continuation. The proposal does not treat measurement as one indivisible physical event. It distinguishes the admission of a measurement interaction and apparatus, durable record formation, later availability of that record, agreement among physical carriers, global outcome standing, quantum-probability weighting, and the rule governing what physical or predictive description continues after an outcome. These burdens can remain open or fail independently. The principal experimental proposal is the Quantum Continuation Closure Test (QCCT). QCCT-I asks whether two physically distinct proper-mixture preparation procedures that are represented by the same admitted standard quantum state can produce different later statistics after the same admitted first measurement. The canonical preparation pair consists of equal-weight Z-basis and X-basis proper mixtures that are represented by the same maximally mixed qubit density operator under standard quantum mechanics. A fixed standard quantum instrument cannot depend on which proper-mixture decomposition produced that state. Published generalized state-update rules provide explicit theory-side foils for which the preparation decomposition can instead remain relevant to the postmeasurement continuation. Ordinary quantum physics is given first refusal. Preparation mismatch, improper-mixture substitution, calibration failure, different first-measurement seats, preparation side channels, ordinary non-Lüders instruments, temporal process memory, and independently warranted expansion of the physical reference must be tested at their own declared scopes before a stronger preparation-indistinguishability violation can be inferred. QCCT therefore does not treat deviation from an ideal Lüders prediction, failure of one fitted instrument, or a preparation-dependent sequential signal as immediate evidence for new quantum dynamics. The comparison architecture escalates from fixed-instrument closure to finite-horizon process-tensor closure and only then to stronger bounded residual claims. The experiment is modular. Prospective QCCT-I execution, process-memory characterization, coarse-graining invariance, archival-data analysis, and later distributed partial closure may contribute distinct local results. A result transfers to a later experiment only through an explicit interface preserving the relevant physical carrier, reference, scope, calibration, provenance, and unresolved burdens. The deposit also contains a machine-auditable formal surface. One consolidated Lean file contains two scientifically distinct Quantum Measurement modules: Seam G, concerning Born weighting / quantum probability measure, and QCCT-I, concerning preparation-indistinguishability / outcome-conditioned continuation. Their shared file packaging does not merge their objects, burdens, evidence states, dispositions, or claims. Both generic machine dispositions remain Not Yet Adjudicable. Seam G retains open domain-owned probability-admission burdens. QCCT-I retains open empirical preparation, reference, measurement, side-channel, comparator, and adjudication burdens. The consolidated Quantum Measurement contracts-and-adapters file was appended directly beneath the unchanged Structural Flow Universal Kernel and elaborated cleanly twice during the release audit. Clean elaboration establishes only that the encoded contracts and adapters coexist coherently at their declared formal scopes. It does not derive the Born rule, establish the physical validity of the generalized continuation family, demonstrate preparation equivalence, close the ordinary quantum comparators, establish an anomaly, falsify standard quantum mechanics, or select an interpretation of quantum measurement. The physical answer remains the responsibility of experiment.
This paper develops a mathematical framework for two-boundary quantum admissibility. Given an initial wave field ψi = √ρiexp(iSi/ℏ) and a final, post-selected, or backward-evolving effect wave field ϕf= √ρf exp(iSf/ℏ), the central question is not merely where both amplitudes are non-zero. The question is whether an intermediate support structure can simultaneously satisfy the transport requirements imposed by both boundaries. The framework introduces a log-transport defect Dα associated with the power-family density ρα = ρα i ρ1−α f transported by the symmetric boundary velocity v= (ui+uf)/2. The defect admits an exact decomposition into an irreducible geometric obstruction, a density-reweighting channel, and one-boundary continuity residuals. This decomposition generates a hierarchy of repair classes ranging from global density reweighting through local density repair and finally to topological obstruction characterized by nodal winding mismatch. The framework lifts naturally from ordinary space to full configuration space, where the primary object is not a trajectory but a connected component of low-obstruction support. These components, termed admissible support tubes, provide a geometric description of conditional event connectivity under two-boundary constraints. The framework does not modify the Born rule, does not introduce hidden signalling, and does not identify weak values with literal particle trajectories. It proposes a diagnostic geometry for conditional quantum support based on exact transport compatibilit
This work closes the microphysical phase-1 sector of protected reduced spinor geometry. Starting from the regular reduced phase plane with one isotropic complex mode, a protected admissible sector, and a detector boundary projector, the paper derives detector-resolved realization channels and shows that the Born rule appears as the normalized quadratic weight of those channels. Measurement is formulated as boundary selection of one admissible continuation, and light-channel realization is described without requiring an underlying microscopic trajectory. The same reduced phase mode is then lifted to a closure spinor by an exact half-angle construction. From this, the paper derives the physical spin-1/2 operator and the exact bare electron gyromagnetic law g = 2. The dressed electron is described through the action excess of its closure cycle. The first reduced geometric share is alpha/(4pi), and quarter-sector self-screening yields the renormalized cycle law Xi_cyc = alpha/(4pi) * (1 - alpha/4), leading to the dressed electron law. In this way, probability, measurement, light-channel realization, spin, exact bare g = 2, and the first dressed electron anomaly are treated as parts of one closed reduced geometric structure. The paper is positioned as the completion of phase 1 of the theory. Its natural continuation is phase 2: the atomic sector, including the minimal electron closure cycle, the principal spectrum, fine structure, and the Lamb-like shift.
Paper XXI completes the microscopic extension of Six-Throat Directed Geometry by introducing a directed spinor dynamics on the regular six-throat spacetime and carrying that dynamics through the exact periodic closure. The construction separates persistent physical identity, directed state, and observer access, so a state may pass through a direction-neutral condition without annihilation while observational localization remains an access restriction rather than a second global evolution law. The microscopic dynamics is formulated with a curved-space Dirac equation containing a directed scalar mass law. At directional zero, the effective mass returns smoothly to its reference value and the spinor evolution remains regular. The associated Dirac current is positive and conserved, providing an invariant microscopic measure through directed reversal. The closed geometry is equipped with an antiperiodic spin structure over the 15.6-length geometric cycle, while bilinear observables remain periodic after one complete spatial circuit. The global construction yields a regular zero passage, a resolved directed spectral splitting, dynamical conservation of the spinor norm, channel-resolved decoherence, and a geometric detector measure. Observer localization is represented by projection onto the observer-accessible subspace while the global physical state remains intact. For flux-orthogonal detector channels, the conserved current partitions according to the squared channel amplitudes. The resulting normalized detector measure reproduces the standard Born weights as a current-flux theorem rather than as a primitive probability postulate. An explicit six-channel detector-surface calculation gives a maximum Born-weight residual of approximately 1.43 × 10^-14, while the integrated cross-channel surface flux remains below approximately 2.22 × 10^-16. The accompanying reproducibility package includes the global kinetic spectrum, parametric mass spectrum, directed spectral splitting, zero-passage dynamics, dynamic channel flux, detector-surface flux, final consistency audit, and the inherited geometric generators required by the calculation chain. The complete numerical outputs are distributed with the package. The result is a microscopic closure in which existence, direction, zero passage, geometric emergence, coherence, decoherence, observer access, and detector statistics are represented within one regular geometric framework.
