[architecture] Cross-session memory leakage between users

Scope long-term memory by a strict user or session namespace at the database or collection level, not just the application level. Enforce hard isolation boundaries using metadata filtering native to the vector store.

Journey Context:
It is easy to query a global vector database for relevant context, but multi-tenant agents will leak PII and cross-contaminate workflows if memory isn't strictly partitioned. Application-level filtering can be bypassed by LLM prompt injection or logic errors. The tradeoff of strict DB-level partitioning is slightly more complex provisioning, but it guarantees isolation.
