This page is organized around the current QDL hierarchy: the canonical QDL roadmap as the top-level program architecture;
the JTAP metrology paper as the first peer-reviewed foundation; the Planck-scale substrate capstone as the substrate architecture;
the Toroidal QDC Knot as the geometric substrate keystone; the QDC Completion Theorem as the completion-theorem spine;
the SMEFT Γ(O) audit companion as the falsifiable operator-governance test; and the charged-lepton / mass-spectrum sequence
as the numerical spectrum application.
The Quantized Dimensional Ledger: A Structural Framework for Dimensional Coherence in Physics
Bourassa, J. D. (2026). Book. DOI: 10.5281/zenodo.18902770
This book is a reader-facing synthesis of the QDL program. The canonical mathematical structure and strongest technical claims remain in the DOI-backed papers and preprints.
Canonical orientation record.
Consolidates QDL from closure admissibility to physical selection and explains the program layers, claim-status firewalls,
failure modes, and near-term validation paths.
QDL substrate architecture.
Defines the substrate as the closure-persistent residue of candidate Planck-scale fluctuation structure,
not a medium, material aether, or hidden substance.
Bourassa, J. D. (2026). Zenodo · DOI: 10.5281/zenodo.20461142
The canonical QDL orientation and program-architecture record. It synthesizes dimensional closure, QDC geometry,
operator governance, mass-spectrum architecture, substrate persistence, measurement-chain integrity, claim-status firewalls,
failure modes, and near-term validation paths.
This record frames QDL as a structural-admissibility program rather than a completed unification theory. It distinguishes
definitions, reconstructions, ansatz-level hypotheses, audits, residuals, and theorem targets so that the program can be evaluated
by explicit claim status and reproducible validation paths.
Journal of Theoretical and Applied Physics, 20(3) · DOI: 10.57647/jtap.2026.2004.05
The first peer-reviewed journal publication for the QDL research program. It establishes the metrology application layer
through dimensional closure, QMU ledgers, and the structural treatment of constants and measurement relations.
May 2026Program capstoneSubstrate architecturePhysical persistence
Bourassa, J. D. (2026). Zenodo · DOI: 10.5281/zenodo.20346814
The QDL substrate architecture record. This capstone defines QDL as a residual-first closure-admissibility theory of physical persistence
and frames the substrate as the closure-persistent residue of candidate Planck-scale fluctuation structure.
Key contributions include a dimensionless Compton–gravity threshold, a charged-lepton mass-ratio reconstruction,
a gravitational QDC-to-curvature bridge, a vacuum-filter toy model, a provisional SMEFT audit criterion,
a full matrix-audit protocol, a measurement-chain closure theorem, and a constants-as-closure-operators interpretation.
May 2026Geometric substrate keystoneToroidal QDCPlanck-scale recurrence
Bourassa, J. D. (2026). Zenodo · DOI: 10.5281/zenodo.20367493
Graphical abstract for the toroidal geometric substrate keystone.
The canonical QDL geometric substrate-mode paper. It models Planck-scale candidate structure as a closure-stable toroidal
two-cycle recurrence knot and gives the substrate capstone a compact geometric persistence object.
The central identity is
QDCT = VTω1ω2 ∼ L3F2,
with closure sequence
Tn,m → QDCT → ΓT(T) → CTQDL = 0 → RTQDL.
Conditional links include a minimal three-family recurrence-class structure, the charged-lepton phase
θℓ = 2/9, Koide occupancy-amplitude closure, vacuum residual selection,
gauge-sector admissibility, non-SM exclusion, the Compton–gravity threshold, and a candidate toroidal QDC Hilbert space.
June 2026Completion theoremStandard-Model admissibilityOpen proof gates
Bourassa, J. D. (2026). Zenodo · DOI: 10.5281/zenodo.20692677
Graphical abstract for the QDC Completion Theorem. The figure separates exact or computed anchors from conditional Standard-Model reconstruction steps and explicitly open completion gates.
The current QDL completion-theorem spine. This record consolidates the route from the Planck-scale toroidal QDC substrate
to local Standard-Model admissibility and gravitational recurrence, using exact anchors, conditional reconstruction gates,
and declared open proof targets.
The theorem-status claim is deliberately controlled: stable physical structure is proposed to arise as a closure-stable projection
of a Planck-scale toroidal QDC substrate. The paper does not claim that every Standard Model constant has been computed. It identifies
the finite gates that must close for QDL to become a candidate substrate-level completion theory.
Scope note: this paper should be read after the roadmap, JTAP metrology foundation, substrate capstone, and Toroidal QDC Knot,
and before the SMEFT audit and charged-lepton numerical sequence.
May 2026SMEFT Γ(O)Operator governanceMachine-readable audit
Bourassa, J. D. (2026). Zenodo dataset · DOI: 10.5281/zenodo.20357001
The falsifiable operator-governance test for the QDL substrate program. This dataset provides representative source-anchored
Warsaw-basis operator assignments, exact/source-anchored rows, strict-zero and compensator targets, verification taxonomy,
data dictionary, changelog, sources table, README, workbook, and package ZIP.
Scope note: v1.0 is a representative source-anchored audit subset and scaffold. It does not claim completion of the full
2499 × 2499 three-generation SMEFT anomalous-dimension matrix, and it asserts no confirmed R-class violations.
May 2026Mass-spectrum sequenceKoide closureNumerical application
Bourassa, J. D. (2026). Zenodo · DOI: 10.5281/zenodo.20328260
The numerical spectrum application of QDL. This synthesis distinguishes derived occupancy-amplitude / Koide eigencone
and relational-phase layers from phenomenological radial closure diagnostics.
The mass-spectrum sequence is now best read after the QDL roadmap, substrate capstone, and Toroidal QDC Knot because the roadmap
provides the program architecture, while the toroidal paper gives a geometric interpretation of three-family recurrence and the charged-lepton relational phase
θℓ = 2/9.

Earlier Foundational Path
Earlier foundational papers and synthesis materials. These remain important, but the current primary entry path is now the seven-anchor hierarchy above.
Nine-paper benchmark sequence · DOI-backed records
The QDL–SO10–1 series applies QDL structural admissibility to an SO(10)-compatible grand-unification benchmark.
The sequence proceeds from benchmark definition through low-energy phenomenology, stress testing, executable gauge closure,
scalar-threshold closure, operator-level proton-decay exposure, flavor/leptogenesis hardening, and integrated capstone synthesis.
The series is not presented as a final theory of nature. It is an executable, falsifiable benchmark program designed to make
QDL-based grand-unification claims auditable and reproducible.
Defines the initial QDL–SO10–1 SO(10)-compatible benchmark, including the symmetry-breaking chain, scales, thresholds, and first proton-decay exposure estimates.
Extracts the low-energy phenomenological consequences of the benchmark, emphasizing indirect signatures, neutrino observables, proton decay, and the absence of broad light charged or colored remnants.
Classifies the benchmark into robust, conditional, and revision-forcing features, with explicit comparison to alternative GUT containers and failure modes.
Paper #4Historical perspective
The QDL Grand-Unification Benchmark in Historical Perspective
Historical perspective · superseded by Paper #9 capstone
Situates the initial QDL–SO10–1 trilogy against SU(5), Pati–Salam, SO(10), supersymmetric GUTs, E6, string/F-theory constructions, and modern nonminimal scans. This perspective is now superseded by the integrated Paper #9 capstone.
Integrates the full sequence into a single executable closure capstone, presenting QDL–SO10–1 as a benchmark-level GUT program rather than a final theory claim.
