Major–Minor Regimes and Compositional Dynamics From Palindromic Structures to Harmonic Composites in Meta-Existence

We present a canonical formulation of compositional dynamics in meta-existence, integrating major–minor regimes, first- and second-order transitions, palindromic admissibility, and chimera hybridization into a unified framework. We show that admissible meta-structures are closed under operations analogous to duplication, inversion, and translocation, giving rise to composite melodic and chordal configurations. First-order transitions produce qualitative regime changes through structural gates, while second-order transitions generate gradual accumulation and fractal dimensional evolution within fixed regimes. Triads and chords emerge as minimal compositional units that necessarily embed both stability and transitional tension. These mechanisms exhibit a structural correspondence with genomic evolution and motivate a hypothesis concerning self-replicating meta-structures. Composition is thus identified as the central process through which meta-existence supports rich, pre-statistical complexity prior to temporal asymmetrization and classical realization.
