Actualization Dynamics and the Informational Universality Class

Technical Summary: Actualization Dynamics (Version 51.2) This manuscript establishes a formal variational framework for the emergence of (1,3) Lorentzian spacetime from a pre-geometric informational substrate. Using a Fisher-Jeffreys reference measure and a dissipative Lyapunov gradient flow, the framework derives the laws of physics as fundamental stability requirements for holographic reconstructibility. Core Scientific Claims: Dimensional Selection: Proof that a 4-dimensional spacetime (3+1) is the unique stable phase for holographic stabilizer codes under the Quantum Singleton Bound. Singularity Resolution: Derivation of a regular de Sitter core through "informational stiffness," providing a non-singular resolution to the Schwarzschild interior where the curvature remains finite. The CMB Smoking Gun: Prediction of a specific, falsifiable log-periodic modulation in the primordial power spectrum with a characteristic frequency of approximately 0.47 (plus or minus 0.03). Keywords: Informational Physics, Holographic Error Correction, Lorentzian Emergence, Discrete Scale Invariance, Quantum Gravity, Cosmic Microwave Background.
