Informational Curvature Theory Paper II - The Informational Rubric Formal Definition & Structure

Abstract 
Informational Curvature Theory (ICT) proposes that observable structure across domains is 
constrained by the organisation of information itself. While prior work introduced 
informational curvature conceptually, a precise operational formalism is required for 
systematic application. This paper presents the informational rubric, defined through four 
coordinated dimensions—entropy gradient (α), modal coherence (β), boundedness (γ), and 
relational resonance (δ). These components are consolidated from earlier formal 
developments and reintroduced here as a closed, domain-agnostic informational operator. The 
rubric constrains admissible structure without prescribing dynamics or modifying existing 
physical laws. This work establishes the formal core upon which subsequent empirical, 
instrumental, and theoretical extensions of ICT are built.
