Report #38993

[frontier] Agents lack long-term memory across sessions and cannot distinguish between episodic and procedural memories

Adopt hierarchical memory tiers: use LangMem to store episodic memories as vector facts and procedural memories as tool definitions, with explicit memory consolidation agents that extract and update stored knowledge

Journey Context:
Simple vector stores mix all memory types, leading to retrieval noise. Hierarchical memory separates short-term \(context window\), working \(compressed\), episodic \(facts about users\), and procedural \(available tools\). LangMem provides the storage and retrieval abstractions for this tiering.
