[architecture] Agent losing all learned user preferences and task context when the session or thread resets

Decouple memory persistence from the session context window. Write critical user facts and long-term task state to an external persistent store at the end of each turn, and hydrate the system prompt or working memory from this store at the start of a new session.

Journey Context:
Many agents are built as stateless functions where the context window is the only state. When the API connection drops or the thread ID changes, the agent forgets everything. The tradeoff is infrastructure complexity \(managing external DBs, serialization\) versus user experience. For any agent meant to build a long-term relationship or execute multi-day tasks, external persistence is non-negotiable. The context window is merely ephemeral RAM; you need a hard drive.
