Entity Understanding Layer (EUL): Canonical Definition

The Entity Understanding Layer (EUL) defines the representational architecture through which AI systems maintain, update, and express coherent understandings of people, organisations, relationships, and ideas. The concept describes how entity meaning is structured and stabilised across internal model representations and cross-system interpretive contexts, without reference to implementation or system internals. This record provides the canonical definition of the Entity Understanding Layer (EUL) as part of the EntityWorks Standard. The Entity Collision Problem (ECP) is a related concept within the EntityWorks Standard describing representational failure modes in AI-mediated interpretation systems.https://doi.org/10.5281/zenodo.19018255
