## Summary by CodeRabbit

* **New Features**
* Added support for a document summary field, allowing documents to
include and display an optional summary alongside the title.

* **Bug Fixes**
* Improved access control when retrieving documents, ensuring proper
permission checks are enforced.

* **Tests**
* Expanded test coverage to verify correct handling of document title
and summary fields, including cases where the summary is absent.
