Agentic Memory Foundations

What you'll learn

• Name the three canonical memory types — semantic, episodic, and procedural — and say what each one stores, where it lives, and when it is read.
• Trace a retrieval pipeline end to end: embed a query, search a vector index, re-rank candidates, and inject the survivors into the prompt as grounded context.
• Explain why naive RAG drifts toward stale answers, and what a freshness layer (last-verified dates, change detection, re-validation) adds on top.
• Sketch a namespace-scoped memory store so that a fact learned for one user, task, or community is not accidentally surfaced to another.
