SOSA-Core: System Architecture for Deterministic Output Control in LLM Systems

This work defines the core architecture of the SOSA (System Operating Writing Assistant) framework, a deterministic system for controlling output generation in Large Language Models. The architecture formalizes a modular pipeline composed of sequential operational states (Position, Pre-Control, Generation, Validation, Delivery) and integrates two primary control layers: Constraint Enforcement (CE) and Minimal Verification Unit (MVU). By separating constraint definition, generation, and validation into distinct phases, SOSA enables reproducible, auditable, and fully regulated text production. This paper establishes the structural foundation of the SOSA system and defines the interaction between its core components.
