[architecture] Storing raw conversation logs and extracted facts in the same vector collection

Maintain separate collections or strict metadata namespaces for episodic memory \(raw event logs\) and semantic memory \(extracted facts\). Query them differently based on the task.

Journey Context:
Mixing raw logs and facts means a search for 'user preference' returns a chunk of a conversation about something else where the preference was briefly mentioned. Semantic memory should be extracted via an LLM \('User likes dark mode'\) and stored as discrete, atomic facts. Episodic memory is for 'what did we do yesterday' \(temporal queries\). Mixing them breaks multi-hop retrieval because the embedding spaces conflict: you either find the right fact but lack context, or find the right conversation but miss the specific fact.
