                Foundational architectural thesis ❗This paper represents months of deep research by the Effector Core Team. We discovered that by applying principles from Harvard Architecture, Linear Logic, and Thermodynamics, we can mathematically prove the efficiency of a reactive system.
              
          
    A Unified Theory of Reactive Business Logic and State Management

Abstract

The contemporary landscape of frontend engineering has reached an inflection point where traditional state management paradigms—focused primarily on data synchronization and propagation—are no longer sufficient for modeling complex, high-entropy business domains. As application scale increases, the primary challenge shifts from the storage of values to the orchestration of capabilities, the enforcement of topological constraints, and the management of polymorphic behavior.
