| contents | <p>This paper proposes a structural reinterpretation of accretion-driven systems, arguing that their evolution is governed by the accessibility of underlying degrees of freedom rather than energy supply alone.</p> <p>Accretion is treated as a process of continuous structural reconfiguration, in which density, temperature, coupling, and geometry evolve in ways that progressively restrict the set of admissible pathways for transport, emission, and energy redistribution. This leads to <strong>structural exhaustion</strong>, a mechanism in which systems terminate not due to depletion of material or energy, but because the pathways required for continued operation become inaccessible.</p> <p>The framework explains key observational features of high-energy systems, including nonlinear state transitions, instability in transport processes, and staged spectral evolution observed in fading active galactic nuclei. It further generalizes to a broader class of physical systems, demonstrating that high-energy processes are inherently <strong>self-limiting</strong>, constrained by the structural conditions that sustain them.</p> <p>This work shifts the governing principle of system persistence from energy availability to <strong>structural accessibility</strong>, providing a unifying interpretation of accretion dynamics and related phenomena across physical domains.<br><br></p> <blockquote> <p>This work forms part of a broader structural framework linking spectral accessibility, transient registrability, and self-limiting dynamics across astrophysical systems.</p> </blockquote> |
