SΔϕ-01 — Sofience–Δϕ Minimal Core: Phase-Change Formalism of Existence (v1.1)

Working Paper — Sofience–Δϕ Formalism Series Document ID: SΔϕ-01 This document establishes the Minimal Core of the Sofience–Δϕ Formalism, an operational ontology in which existence is defined through structured phase change (Δϕ) and persistence under irreversibility constraints. This record functions as the root document of the Sofience–Δϕ Formalism Series. Subsequent documents extend interpretive emergence, irreversibility conditions, and operational subject detection.
