Report #75594

[architecture] Agent creates duplicate or conflicting memories for the same entity across sessions \(e.g., 'User likes Python' and 'User prefers Java'\)

Implement an entity extraction and resolution step before writing to long-term memory. Check if a memory about an entity already exists; if it does, update the existing memory node rather than appending a new one.

Journey Context:
Naive memory implementations just upsert new embeddings for every extracted fact. Over time, the DB fills with contradictions \('User is married' vs 'User is single'\). This poisons retrieval because both will be returned with high similarity. The write path must be smart: extract the entity/subject, search the DB for existing memories about that entity, and use an LLM to merge or overwrite the old state with the new state before saving. This requires a read-before-write pattern for memory updates.
