## TL;DR

Retrieval access control prevents RAG systems from returning documents, chunks, fields, or citations that the current user is not allowed to see.

## Core Explanation

RAG systems often index private documents from many tenants, teams, repositories, or data sources. The retriever must carry access metadata and enforce permission filters at query time, not after the model has already seen restricted context.

Agents should treat permission filtering as part of retrieval correctness. A result is not citation-ready just because it is semantically relevant; it also has to be authorized for the current principal.
