# Download the annotated evidence crop for a defect_evidence row

`GET /defect-evidence/{evidenceId}/download`

Renders the downloadable artifact for one defect_evidence row on
demand. When the row carries a bbox, the response is the ORIGINAL
photo cropped to a square window with 30% margin around the bbox and
the bbox stroked in the defect's priority color — exactly what the
platform's evidence viewer shows on screen. When the row has no bbox
(non-CVAT-sourced evidence), the original object is streamed
unmodified. Replaces the retired stored crop derivatives.

## Response `200`

Annotated crop JPEG (or the original object when no bbox)
