Report #74840

[architecture] Agent carries over context or instructions from a previous user session into a new session

Enforce strict session isolation by namespacing memory stores with a session\_id and user\_id. At the start of a new session, initialize a completely fresh context window. Only load cross-session memories \(like user preferences\) via explicit retrieval from a long-term store, never by inheriting the previous session's raw context window.

Journey Context:
When building stateful agents, it is tempting to reuse the conversation history or system prompt modifications from the last interaction to maintain continuity. This causes catastrophic context bleeding, where the agent assumes it is still working on the previous task. The tradeoff is between user convenience \(remembering what they were doing\) and agent reliability. The right architectural call is strict isolation: the context window is ephemeral per session, and persistence is only achieved through structured, queried long-term memory, preventing old state from polluting new tasks.
