END Theory 2.0: The Evans Relational Framework — Technical Reference Edition

END Theory 2.0 (Evans Relational Framework / Evans Node Dialect / Matrix Node Theory) is an independent relational-physics research programme investigating whether discrete relational dynamics can provide a common mathematical framework for emergent fields, geometry, quantum observables, cosmology, and experimentally testable phenomenology. This Technical Reference Edition separates established mathematical results from proposed physical bridges and unresolved closure conditions. The framework develops a scalar-graph benchmark with discrete variational dynamics, normal modes, lattice dispersion, stability conditions, discrete invariants, and finite-spacing gauge covariance. It then formulates explicit construction and closure programmes for graph evolution, continuum limits, gauge and matter structure, quantum probability, operational geometry and gravitation, the EQEF cosmological sector, and detector-level phenomenology. The reference edition uses a controlled claim grammar distinguishing definitions, derivations, proposals, conditional results, measured inputs, calibration, tests, and unresolved closure requirements. Experimental dossiers address GWOSC, CERN collider data, XENONnT, DUNE, DESI, Planck, Euclid, and transient timing through explicit forward-model, identifiability, likelihood, falsification, and reproducibility requirements. The work does not claim empirical confirmation of a unified theory. Rather, it specifies a falsifiable research programme, identifies the mathematical sector presently available for independent checking, and states the additional theoretical and empirical constructions required before broader physical claims can be established.
