+### Full 3D reasoning (DoF=3)
+
+**Task variant:** `3D DoF=3` (unconstrained placement along X, Y, and Z)  
+**Question:** What is the relative position of the cube to the cylinder?  
+**Answer:** `(-X, +Y, +Z)`  
+The full sample contains six views; three are shown here.

+### Single-view 3D task
+
+**Task variant:** `3D Single View`  
+**Question:** What is the relative position of the cube to the cylinder?  
+**Answer:** `(-X, +Y, +Z)`  
+Unlike the multi-view variants, this sample exposes only one isometric view.

+
+### Grid-assisted three-view task
+
+**Task variant:** `2D Three Views Grids`  
+**Question:** What is the relative position of the cylinder to the sphere?  
+**Answer:** `(0X, -Y, -Z)`  
+The projected coordinate grids provide additional alignment cues in each view.

+### Rotated-coordinate task (90°)
+
+**Task variant:** `2D Three Views Rotation (90°)`  
+**Question:** What is the relative position of the cube to the cone?  
+**Answer:** `(+X, 0Y, -Z)`  
+The coordinate frame is rotated to test whether the model follows the visible
+axes rather than relying on a conventional orientation.

+
+### Multi-agent three-view task
+
+**Task variant:** `2D Three Views multiagent (Rotation 0)`  
+**Question:** What is the relative position of the sphere to the cone?  
+**Answer:** `(-X, -Y, +Z)`  
+Each view has its own axis-pair prompt (`front_question`, `side_question`, or
+`top_question`) so three view-specific responses can be combined into the
+full XYZ answer.
+
+| Front agent: XZ | Side agent: YZ | Top agent: XY |
