# Retrieval and SIP

> Retrieve governed context and build the SIP.

## Overview

Retrieval is how context leaves EDN. You search stored records, or build a SIP
for a session, and EDN returns a deterministic, provenance-gated set of records
your model can consume. See [Core concepts](/developer/core-concepts) for how
retrieval and the SIP work.
