Report #75102

[architecture] Previous session context bleeding into new unrelated session

Scope memory retrieval by session ID or thread ID, and explicitly clear ephemeral working memory between distinct tasks, only persisting cross-session knowledge to a long-term store after validation.

Journey Context:
When an agent serves multiple users or handles distinct tasks sequentially, embedding all interactions into a single vector namespace causes cross-contamination. User A's preferences bleed into User B's answers. The fix is strict namespace isolation \(e.g., user\_id or thread\_id metadata filtering\) for retrieval, and treating the context window as ephemeral scratch space that is wiped clean when a new session starts, only persisting validated, generalized facts to the global or user-scoped long-term memory.
