Coherence Intelligence Architecture (CIA) is defined as a layered framework that explains how system behavior emerges through the interaction of distinct structural layers. This paper integrates five layers—substrate, field, topology, coherence, and intelligence—into a unified structure without redefining their individual roles. Each layer contributes a specific condition: substrate defines what is possible, field mediates interaction, topology determines arrangement, coherence establishes alignment, and intelligence enables response. System behavior is understood as the result of how these layers operate together rather than from any single layer in isolation. The architecture addresses limitations in approaches that analyze systems through isolated factors such as components, interaction rules, or performance. By organizing behavior across multiple layers, CIA provides a structured basis for identifying how variation, stability, and failure emerge within systems. This paper does not introduce new concepts or extend the architecture beyond its defined layers. It establishes the relational structure through which system behavior can be understood as coordinated layer interaction across domains.
