### Folder

A hierarchical container for organizing entities, notebook entries, and other items within a Project. Folders support nested structures through parent-child relationships (see `parent`), enabling users to create logical groupings that mirror laboratory organization or experimental workflows. Folders belong to a Project (see `project`) and inherit access control through collaborations (see `Collaboration`). Items stored in folders implement the FolderItem interface. Folders can be starred for quick access (via `Starrable`) and archived with lineage tracking that affects contained items (via `ArchivableWithLineage`).

- `__typename` (string, optional)
- `archiveReason` (string, optional, nullable)
- `archived` (boolean, optional)
- `children` (string, optional) — The folders directly nested under this folder.
- `createdAt` (string, optional)
- `description` (string, optional, nullable)
- `id` (string, optional)
- `modifiedAt` (string, optional, nullable)
- `name` (string, optional, nullable)
- `parent` (FolderRef, optional, nullable) — The parent folder, if it exists. Root folders (one per Project) have no parent.
- `project` (ProjectRef, optional, nullable) — ID of the containing project
