Standing Localization and the Structural Inevitability of Life (standalone version)

This paper develops a structural argument showing that life-like organization is not a contingent or accidental feature of viable physical regimes, but a necessary consequence of minimal constraints on explanatory physical description. Rather than addressing biological origins, evolutionary mechanisms, or probabilistic frequency, the paper operates at a prior level: it asks what any physical regime must permit in order for physical descriptions to retain explanatory standing at all. The analysis isolates three such constraints—localization, exclusion of global coordination, and stability of reference under admissible reformulation—and shows that, once these are enforced, only one persistence strategy remains available to localized structures. By exhausting alternative persistence strategies, the paper demonstrates that persistence under generic environmental perturbation necessarily forces internal regulation. This regulation is shown to decompose into a minimal, irreducible set of features—selective exchange, boundary maintenance, and perturbation-responsive feedback—which are structurally equivalent to what is here called minimal life-like organization. The resulting inevitability claim is conditional and structural, not biological or metaphysical: any physical regime capable of supporting localized explanatory coherence must admit life-like structures in this minimal sense. Although the result is compatible with a broader internal research corpus concerned with standing, admissibility, and explanatory coherence, the paper is fully self-contained. All concepts are defined operationally, no corpus familiarity is assumed, and no external framework commitments are required. The paper is intended to be readable and assessable by non-corpus audiences in foundations of physics and philosophy of physics, while also serving as an internal consolidation point within the larger research program.
