Phase 5 · Long-Term Memory

Give agents durable recall — semantic, episodic and procedural memory, context-window engineering, and long-term memory stores that survive across sessions

Distinguish semantic vs episodic vs procedural memory and when each applies
Engineer the context window: compression, dynamic assembly, windowing
Persist long-term memory with vector + metadata stores (e.g. LangMem)
