Report #82908

[architecture] Agent loses all learned preferences and context when the session ends, forcing user re-onboarding

Maintain a hot 'user profile' document \(updated on write\) and a cold 'episodic' vector store \(queried on demand\). Inject the profile into the system prompt on session start, rather than querying the vector store for every message.

Journey Context:
Cross-session memory often fails because agents try to dynamically retrieve everything on the next session, leading to cold-start latency and context bloat from irrelevant past interactions. The right pattern is to maintain a continuously updated, highly compressed profile for core preferences, and leave detailed event logs in episodic memory. Tradeoff: the profile might get stale if not updated properly, but it guarantees zero-latency personalization on session start.
