# Module: Dataset service

## Purpose

**Dataset Explorer** backend: paginated grid, detail, status updates, bulk status — **`[Authorize(Policy = "DATASET")]`** per suite note on PATCH status (`01_annotations.md` §3 points to `09_dataset_explorer.md`).

## Code

- `DatasetService` — queries tuned for dataset views; may reuse annotation entities.
- `DatasetController` — `[Route("dataset")]`.

## DTOs (this module)

- `GetDatasetQuery`, `DatasetItem`, `ClassDistributionItem`, `BulkStatusRequest` — and shared `UpdateStatusRequest` where used for PATCH.

## Dependencies

Database, same status enums as annotator.

## Suite doc

Primary behavioral spec: `suite/_docs/09_dataset_explorer.md`; permission cross-ref in `01_annotations.md` §3.
