arXiv: MemMachine — Ground-Truth-Preserving Memory System for Personalized AI Agents (2604.04853)

arXiv·medium signal

MemMachine introduces an open-source memory architecture integrating short-term, long-term episodic, and profile memory with a ground-truth-preserving design. Unlike existing approaches that allow memory drift, MemMachine anchors stored knowledge to verifiable sources and provides explicit provenance tracking. For builders implementing persistent agent memory (similar to MindPattern's own memory system), this provides a concrete architecture for avoiding the hallucinated-memory problem.
