Report #70546

[frontier] Agent loses track of long-term task context and user preferences across sessions

Implement three-tier memory: working \(in-context\), episodic \(vector store of past sessions\), semantic \(compressed user model\); use MemGPT-inspired OS-managed paging between tiers

Journey Context:
Simple RAG retrieves noise; infinite context windows hallucinate and lose signal. Hierarchical memory explicitly manages what stays in context vs. gets paged out, similar to OS virtual memory. The breakthrough is the 'memory manager' LLM that decides what to evict and compress. It replaces simple summarization which loses structured data; this preserves relationships.
