Relaxation-Driven Cyclic Cosmology with Higgs Fusion v2.0

This is v2.0 of the conceptual companion "Relaxation-Driven Cyclic Cosmology with Higgs Fusion". It builds upon and extends the original v1 document (https://zenodo.org/records/18238411) by integrating refinements from RDCC core v16.0 (https://zenodo.org/records/18388123), including precision two-sector dynamics, mirror thermodynamics v2.0, bounce–BH duality v2.1, and enhanced GW forecasts v2.0. The fusion identifies the RDCC complex scalar field Φ with the Higgs field (effective singlet description after electroweak symmetry breaking). The small asymmetry parameter ε is reinterpreted as a cosmological echo of Higgs spontaneous symmetry breaking – a subtle structural "tilt" that preserves global CPT symmetry while seeding sectoral relaxation, dark energy, and dualities across scales. The identification is structural and interpretative (not dynamical or energetic): cosmological evolution occurs at ultra-low energies, far below the electroweak scale. No new degrees of freedom, symmetries, or interactions are introduced; the fusion remains purely conceptual and fully consistent within effective field theory below a high-energy cutoff.
