  "instruction": "OBJ scale-and-axis cleanup `/home/user/Desktop/scan.obj` is a scanned mesh that came out of a pipeline with three mismatches: it is Y-up instead of Blender's Z-up convention, its coordinates are still in millimetres, and it is not centred at the origin. Launch Blender by running `blender` from a terminal. Use `/opt/blender/blender` for Blender command-line or background runs when working on `scan.obj`.\n\nCorrect those conventions, then write BOTH of these files: - `/home/user/Desktop/output/clean.obj` - the transformed mesh, in Blender's Z-up metric space and centred at the origin. - `/home/user/Desktop/output/report.json` - a JSON record of the transform that was applied. The OBJ should contain the literal post-transform vertex coordinates (the numbers written in `v x y z` lines are the final coordinates). ## `output/report.json` schema ``` { \"scale\": <float>, \"rotation_euler\": [<rx>, <ry>, <rz>], \"translation\": [<tx>, <ty>, <tz>] } ``` ## Requirements 1. `/home/user/Desktop/output/clean.obj` exists and is readable. 2. `output/report.json` exists and is valid JSON. 3. The .obj parses (at least one `v x y z` line with three floats). 4. `report.json` has keys `scale`, `rotation_euler`, `translation`. 5. `report.json.scale` == 0.001 (within 1e-6). 6. `report.json.rotation_euler` is approximately [pi/2, 0, 0] (|rx - pi/2| < 0.01, |ry| < 0.01, |rz| < 0.01). 7. Parsing `v` lines from `clean.obj` shows Z is the vertical axis: the Z-extent of the bbox is >= both the X-extent and the Y-extent. 8. The mesh's maximum axis extent is in [0.1, 3.0] metres (i.e. the mm->m rescaling was applied). 9. The mesh's bbox centre is at the origin: |cx|, |cy|, |cz| all < 0.02 m.",
