Report #23946

[architecture] When a user corrects themselves or facts change, the vector store contains both the old and new fact, leading the agent to randomly choose the wrong one

Implement entity-based memory upsertion \(Knowledge Graph\) or a consolidation step where new memories explicitly invalidate or overwrite older memories associated with the same entity, rather than just appending.

Journey Context:
Append-only vector stores are terrible for mutable state. If a user says 'My favorite color is blue' and later 'It's red', the DB has both. The agent might say 'Your favorite colors are blue and red'. You need entity resolution and state mutation to maintain a single source of truth for current facts.
