The Jestin Cycle and the Structure of Becoming: Modal Echo, Preference, and Memory in the Jestin Modal–Actuality Framework

This paper refines the Jestin Modal–Actuality Framework (JMAF) by clarifying the structural mechanisms underlying modal divergence, contraction, and actualisation. Jestin’s Constant (J) is presented as a scale free structural invariant that bounds the degree of modal differentiation within any modal field. The framework introduces a primitive ordering relation—the modal metric—which ranks modal configurations by degree of differentiation and enables threshold comparison with J. From this invariant and metric follow three emergent phenomena: modal echo, modal preference, and modal memory. Contraction is reconceived as a form of constrained indeterminacy, a structure preserving projection that is neither deterministic nor random. The paper also includes a symbolic narrative analogy, drawing on the archetypal story of Adam and Hawa, to express the existential meaning of the cycle without making historical claims. The result is a coherent metaphysical system in which bounded modal differentiation becomes a transcendental condition for determinate identity and classical stability.
