[architecture] Agent losing user context across sessions or mixing up different users

Partition memory by namespace \(user\_id, session\_id, agent\_id\) at the database or collection level, not just metadata filtering. Use explicit memory initialization routines at the start of a session.

Journey Context:
A common mistake is using a single vector collection and relying on metadata filters for isolation. This leads to cross-contamination if filters fail, and degrades ANN index performance due to skewed distributions. Strict namespace partitioning ensures isolation. Furthermore, agents need a boot sequence to load core memories into working context, rather than querying a cold DB for every turn, trading initial latency for consistent context grounding.
