This document is an L4 Structural Realization () within the (Energy Emergence Theory) framework, positioned as the particle-domain instantiation of the Standard Model. It is the direct downstream companion to QFT/Gauge Theory REAL v1. 0 --- that document provides the mathematical framework of gauge field theory (graph connection convergence, Yang-Mills dynamics, path integral, renormalization, constraint jamming) ; this document instantiates that framework for the specific particle content of the Standard Model. It receives constitutional provisions from eight upstream sources: seven mother texts (Particle Ontology v3. 4, Mass Ontology v3. 2, Interaction Ontology v2. 1, Constraint Ontology v3. 3, Two Forms of Energy v3. 4, Constraint Network Dynamics v4. 0, and Quantum Mechanics Ontology v3. 1) plus the complete mathematical framework of QFT/Gauge Theory REAL v1. 0. It also inherits domain interfaces from EM REAL v2. 0 (photon constitutional identity) and Nuclear REAL v2. 0 (hadrons as composite constraint vertices). This document accomplishes five core constitutional working tasks. Part I: Constitutional Architecture of Particle Physics in. The eight upstream sources are systematically registered with their constitutional division of labor, establishing the precise constitutional identity of particle physics through six nested propositions --- from the definition of a particle as a Type I constraint vertex through the emergence of species from Capture Window dynamics to the constitutional basis of particle decay as dual-channel damping. The 19 Standard Model parameters are systematically disposed into EET constitutional categories, the constitutional definition of a free particle is established, and the methodology of scattering experiments is given its constitutional foundation. Part II: Particle Spectrum --- The 61 Species Template Condition. The finitude of particle species is a constitutional theorem: the Template Condition (CND v4. 0, ) establishes that de novo constraint formation without a pre-existing structural template is constitutionally impossible. The 61 elementary particle species of the Standard Model are the frozen record of constraint templates captured during the early-universe Capture Window, when the cosmological (t) trajectory simultaneously satisfied >1, A (t) b^form, and ₄ₑₒ₈ₒₓ>₃₄₂₈ₒ₈₎₍. The three fermion generations are three template replication layers deposited during three distinct Capture Windows. This Part is fully independent of QFT/Gauge Theory REAL and constitutes this document's most constitutionally self-contained contribution. Part III: Hadron Spectrum --- From Constraint Jamming to Hadron Masses. Receiving the jamming quantitative mapping ₛ and the string tension /J from QFT REAL Part VI, this Part derives the meson and baryon mass spectra from the Laplacian eigenmodes of the jammed color subnetwork, including Regge trajectories, glueball masses, exotic hadron configurations, the chiral condensate as constraint vertex pairing density, the current versus constituent quark mass distinction, and the constitutional basis of color confinement and hadronization. Part IV: Electroweak Sector --- Chirality, Higgs Template, and Mass Generation (R4--R5). This Part is organized in two sub-parts. Part IV-A formalizes chiral boundary conditions (R4) as the L/R orientation labeling of Type I constraint vertices on the SU (2) L subnetwork, derives the Weinberg angle as a graph connection projection, establishes CPT in the particle domain, and provides the complete anomaly cancellation framework including flavor universality from template representation inheritance. Part IV-B derives the Higgs template coupling (R5) as the template-congestion-driven generation of constrained-state energy Ec for W/Z bosons during the electroweak Capture Window, establishes the constitutional basis for the photon's retained masslessness through six convergent constitutional paths, provides the constitutional clarification of the two distinct mass generation types (Goldstone absorption versus template overlap), and covers electroweak precision observables including custodial symmetry and SMEFT Wilson coefficients. Part V: Gauge Group Rank and Bare Coupling Constants (R6. 1--R6. 3). This Part derives the gauge group rank as a topological invariant of the constraint network's graph automorphism structure: the three factors correspond to the three irreducible constraint subnetwork types (color-jammed, weak-doublet, electromagnetic-phase). It provides the constraint network expressions for the bare gauge couplings and derives the constitutional basis for ₄₌ (1) 1/137, ₛ (1), and W (1) from the spectral properties of their respective constraint subnetworks, including the special constitutional status of ₛ as the only coupling that grows at low energy scales. Part VI: Particle Physics Completion --- Generations, CKM, Neutrinos, and Decay. This Part completes the Standard Model instantiation with the CKM matrix as the transformation between non-commuting constraint projections across different template layers, including the GIM mechanism as template layer orthogonality and the Wolfenstein parameter hierarchy from Capture Window chronology; neutrino masses as the mass quantum floor of the shallowest constraint layer, including the mass hierarchy prediction (normal ordering as constitutional expectation) and the Dirac versus Majorana constitutional contingency; and particle decay widths as the dual-channel damping expressed in the particle domain, with decay chains as constitutional manifestations of the mass irreversibility theorem dm/dt 0. The constitutional identity of particle physics in is established by six nested propositions. P1: Particle = Type I constraint vertex with constrained-state energy Ec>0 --- Matter, defined by N 1, Ec>0, and mass m=Ec/v_²>0. P1-bis: Boson-Fermion Distinction = Type I/Type II Exclusivity --- the exclusive capacity limit of Type I vertices produces fermions and Pauli exclusion, while the non-exclusive nature of Type II edges permits bosonic coherent superposition. P2: Particle species = constraint templates fixed during the early-universe Capture Window --- the Template Condition guarantees that the 61 species are the complete set, not an arbitrary collection. P2-bis: Entanglement = shared constraint boundary established during co-formation events --- the constitutional root of all non-classical correlations in particle physics. P3: Particle mass = the scalar projection of constrained-state energy, m=Ec/v_², with three constitutionally distinct sources: Higgs template coupling, constraint configuration energy, and constraint vibrational kinetic energy. P4: Particle interactions = constraint vertex coupling through Type II edge graph connections, operating through exactly three irreducible mechanisms (edge-weight modulation, template exchange, jamming modulation). P5: Particle decay = constraint meltdown events governed by the dual-channel damping formula ₓ₎ₓ₀₋=₄₋₀ₒₓ₈₂ () +₋₀ₒₓ₈₂ (C (t) ), with each decay permanently recorded in the cosmic plastic inertia budget C (t). This document provides the constitutional foundation for the complete Standard Model particle spectrum. It establishes ten distinctive constitutional contributions that the Standard Model cannot provide on its own terms: (1) the 61 species are not an arbitrary collection --- they are a constitutional consequence of the Template Condition; (2) the three generations are not free parameters --- they are the historical record of three Capture Windows; (3) the fermion mass hierarchy is not random --- it is the natural result of decreasing across successive Capture Windows combined with template overlap differences; (4) the CKM hierarchy is a decreasing pattern of template non-commutativity, not a random matrix; (5) the smallness of flavor-changing neutral currents is not fine-tuning --- it is template layer orthogonality; (6) the photon's masslessness is not a coincidence --- it is guaranteed by six convergent constitutional paths; (7) the hierarchy problem requires neither SUSY nor anthropics --- the electroweak and gravitational constraint subnetworks are different graphs that do not share constraint edges; (8) the LHC's failure to discover new particles is not a ``desert'' --- the Capture Window is closed; (9) dark matter's absence from the Standard Model is expected --- the 61 species are all the templates fixed during the Capture Windows; (10) gauge couplings are universal while Yukawa couplings are not --- this is template representation inheritance versus template overlap difference. This document strictly complies with all rules of the Universal Writing Constitution v1. 6. It forms a co-creation pair with QFT/Gauge Theory REAL v1. 0: the two documents share the same constitutional foundation, version synchronization, and cross-referencing structure. All and constitutional content belongs to the upstream mother texts and QFT REAL. New content at the and levels is explicitly labeled.
