  "instruction": "Purge Orphan Datablocks `/home/user/Desktop/scene.blend` contains a mesh\nobject `Cube` that uses `Mat_InUse`, which in turn uses `Img_InUse`. Launch Blender by running `blender` from a terminal. At the start of the task, use `/opt/blender/blender` for Blender command-line or background runs when working on `scene.blend`.\n\nThe file is cluttered with 12 fake-user materials and 6 fake-user images.\nSome orphan materials reference some of the orphan images, so the cleanup\nmust be done carefully: remove the unused materials and then remove any\nnow-unreferenced images, without disturbing `Cube`, `Mat_InUse`, or\n`Img_InUse`.\n\n## Requirements\n1. `/home/user/Desktop/answer.blend` opens as a valid Blender file.\n2. `Cube` still exists and its first material slot is `Mat_InUse`.\n3. `Mat_InUse` exists.\n4. `Img_InUse` exists.\n5. No `Mat_Orphan_*` material remains.\n6. No `Img_Orphan_*` image remains.\n7. `len(bpy.data.materials) == 1`.\n8. Exactly one user-created image remains.\n\nDo not rename `Cube`, its material, or its image; only purge the orphaned\ndatablocks.",
