Flexion Framework V3.1: Structural Ontology of Existence, Life, and Manifestation

The Flexion Framework V3.1 establishes a minimal structural ontology defining the necessary and sufficient conditions for structural existence, life, admissible futures, and collapse. Existence is viability-conditioned (κ > 0). Life is defined as interpretive continuation within a structurally bounded admissible future space. Collapse marks the irreversible termination of viability. Manifestation is ontologically distinct from existence. The framework is intentionally closed: no operator defined at this level expands admissible futures, restores exhausted viability, reverses collapse, or violates structural invariants. This work defines the foundational layer of the Flexion Universe, upon which higher-level theories such as Flexion Dynamics, Flexion Intelligence Theory, Flexion Entanglement Theory, and Observer Theory are constructed.
