ABSTRACT: This paper describes the Extended General Intelligence (EGI) framework, a five-layer cognitive architecture that integrates semantic world modeling with persistent multi-agent reasoning. EGI organizes perception, semantic understanding, collaborative reasoning, orchestration, and meta-cognition into a unified structure, in which world-model information is represented as explicit semantic state variables shared across-agents. To illustrate how this architecture can be used in practice, we implement a multi-agent financial intelligence system and apply it to five years of central bank communications, macroeconomic indicators, risk factors, and market data (2020-2025). The system produces central bank tone indices, macro and risk-regime inferences, and market-reaction expectations. A comparative evaluation against a flat, single-prompt baseline suggests that the EGI-based design yields more stable semantic trajectories and more coherent cross-domain reasoning. The framework is intended as an architectural blueprint that may support further research on interpretable, long-horizon multi-agent intelligence.
