Operational Identification of Self-Sustaining and Observer Field Regimes

This work proposes that certain persistent structures in the universe are best understood not as objects placed in spacetime, but as stable configurations of the spacetime field itself. It focuses on configurations that remain coherent far from equilibrium by continuously absorbing, transforming, and redistributing energy and matter, rather than relaxing toward dissipation. Some of these configurations exhibit a further property: their future evolution depends not only on present conditions, but on internally retained interaction history. The framework treats such structures as field regimes characterized by persistence, internal mediation, and proper-time stability, using only established field-theoretic language. No assumptions are made about biology, agency, or microscopic mechanism. The result is a way to identify self-maintaining and observationally active structures as intrinsic features of the spacetime field, analogous in status to other field-defined phenomena whose physical meaning emerges through use rather than declaration.
