THE BACK‑END LAW A Universal Informational Structure Governing Irreversible Transformation Across Coherent Systems

This paper formalizes the Back‑End Law, a substrate‑independent informational principle governing irreversible transitions across coherent systems. The law states that any system with coherence, irreversibility, and informational persistence will undergo a five‑stage transformation—Collapse, Threshold, Irreversibility, Reorganization, Stabilization—when its front‑end structure fails. Evidence from physics, biology, cognition, and complex systems demonstrates cross‑domain invariance of this sequence. The law is falsifiable: it would be disproven by any system meeting the three criteria that fails to reorganize into a stable attractor. Near‑term predictions are testable using current computational and systems‑level tools, while long‑term “Final Boss” tests in quantum gravity, biological reorganization, and chaotic systems offer ultimate confirmation. The Back‑End Law is proposed as a universal informational structure underlying collapse and reorganization across natural and artificial systems.
