# Overview

> EDN as a governed memory layer between your application and your model.

## A governed memory layer

EDN sits between your application and the language model you choose. Your
application writes content into EDN and asks EDN for context. EDN stores that
content, classifies it by where it came from, and returns a compact, governed
package of context that your application places in front of its model.

EDN does not call a model to answer questions and does not route to a provider.
The model is yours. EDN's job is to make the context that reaches your model
honest and traceable.

## What "governed" means here

Every record EDN holds carries a provenance class that records its origin, for
example a fact the user stated, a fact confirmed by the user, a fact verified
from a document, or an AI inference. Retrieval and context assembly respect
those classes: inferences are never presented as established facts, and
AI-generated content is kept out of the sections your model treats as ground
truth.
