Abstract
Volume I establishes the invariant α c λ = 1 as the dimensionless equilibrium linking temporal coupling, propagation, and linear density. It introduces the temporal stiffness parameter γ and the normaliser ξ, derives the intrinsic temporal–electromagnetic correspondence, and demonstrates that all classical constants (G, ℏ, e, ε₀, μ₀) arise as projection coefficients of a single substrate. This volume unifies gravitational curvature, vacuum impedance, gauge stiffness, and quantum coherence within a coherent algebraic triad, and sets out the immediate empirical predictions of the framework.
