LiNDA OS: A Deterministic Multi-Agent Cognitive Architecture with Hybrid Graph- Vector Memory Consolidation

Modern implementations utilizing Large Language Models (LLMs) are structurally constrained by their stateless execution characteristics. Conventional attempts to integrate long-term contextual persistence commonly depend on primitive semantic retrieval mechanisms, such as standard Retrieval- Augmented Generation (RAG) [2]. As the underlying database scales, these standard retrieval systems generate significant cognitive noise, resulting in performance degradation and non-linear modelhallucinations. This document introduces LiNDA OS (Local Intelligent Networked Digital Assistant)— a fully localized, deterministic, multi-agent operating system structured around an advanced Plan- and-Execute operational framework. The core technical contribution of this work is a biologically- inspired, four-layer memory hierarchy managed by an Asynchronous Dream Consolidation Pipeline (ADCP). This pipeline effectively decouples real-time user-facing operations from the resource- intensive process of structural memory formation. Running as an asynchronous background task, the system resolves factual conflicts, deduplicates redundant conceptual entities, and translates highly fragmented episodic inputs into a persistent semantic network constructed upon a Hybrid Graph- Vector RAG architecture utilizing Temporal Edge parameters. Enhanced by a stateful task re- evaluation loop, hard execution guardrails (Fail-Closed Guardrails), and a multi-tenant Relational Self-Modeling framework, LiNDA OS presents a secure, cryptographically isolated, and structurally stable cognitive foundation suitable for scalable B2B and enterprise environments.
