GRAVITY: Architecture-Agnostic Structured Anchoring for Long-Horizon Conversational Memory
GRAVITY introduces a plug-and-play module that injects structured knowledge into long-horizon conversational agents' prompts at generation time. It extracts entity profiles, temporal event traces, and cross-session topic summaries to provide relational, temporal, and thematic context. This method addresses the failure of existing systems to connect scattered evidence by explicitly structuring it for better reasoning.
