Contextual Memory Virtualisation: DAG-Based State Management and Structurally Lossless Trimming for LLM Agents

Researchers introduce Contextual Memory Virtualisation (CMV), a system that preserves LLM understanding across extended sessions by treating context as version-controlled state using DAG-based management. The system includes a trimming algorithm that reduces token counts by 20-86% while preserving all user interactions, demonstrating particular efficiency in tool-use sessions.
