This document discloses a complete system architecture for building domain-specic AI consultation systems from authoritative source texts. The architecture, designated Object- Oriented LLM (OO-LLM), decomposes the monolithic large language model paradigm into four cooperating components: a Translator (human interface layer), a Domain Model (corpus-constrained reasoner), a Computation Engine (deterministic fact producer), and a Knowledge Store (versioned retrieval-augmented database). A fth cross-cutting compo- nent, the Governance Protocol, enforces output quality constraints at every data exchange boundary. The architecture is domain-agnostic: the same structural framework applies to any classical or authoritative knowledge tradition. This document describes the architec- ture in sucient technical detail to constitute prior art under 35 U.S.C. Ÿ102, preventing patent claims over the described methods, their obvious variants, and their domain-specic instantiations.
