Report #22571
[frontier] Flat vector stores fail to distinguish between working memory, episodic events, and semantic knowledge
Implement hierarchical memory: limited-context working memory \(LLM context window\), vector-based episodic memory \(recent events\), and graph-based semantic memory \(core knowledge\) with explicit transfer between layers
Journey Context:
Monolithic RAG confuses temporary tool outputs with permanent knowledge. The insight from MemGPT and cognitive architectures is explicit memory tiers: working \(limited\), episodic \(searchable history\), semantic \(structured facts\), with agents managing overflow via function calls \(e.g., 'archival\_memory\_search'\).
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
