Report #1353

[architecture] Agent stores conflicting or duplicate memories about the same entity across sessions, leading to unpredictable behavior based on which memory is retrieved

Structure long-term memory as a Knowledge Graph \(entities and relations\) rather than just unstructured text chunks. When updating a fact, perform an upsert on the entity node rather than appending a new memory chunk.

Journey Context:
Unstructured vector stores are append-only. If a user changes their preference, adding the new preference creates a conflict with the old one. Cosine similarity might retrieve the old one. While semantic consolidation can help, a more robust architectural pattern for state tracking is using a Graph RAG or entity-centric memory store where facts are tied to entities and can be explicitly updated or invalidated, preventing contradictory retrievals.
