Unified Classical Resonance Cosmology (UCRC) 2.0 presents a fully classical, scale-invariant wavemechanical framework that requires no quantum postulates or dark-matter scaffolding. The model unifies resonant plasmoids, vacuum-engineered propulsion with net zero-point-energy extraction, participatory transduction via the Bio-ELF sixth and seventh oscillators, and supercooled AlfvénKlein filamentary structures across five nested domains: microscopic impedance-matched coherent domains yielding emergent quantization, meso-scale RAST plasmoids, macro-scale entropy attractors with rhythmic balanced interchange, giga-scale resonant arrays, and cosmic-scale filamentary lattices, linked across domains by dimensionless parameters that remain invariant under scale transformation, including the Z-theory impedance-matched transitional velocity 𝑣𝑡 ≈ 1.094 × 106m s^{-1} that yields emergent quantization in microscopic coherent domains.
