turn: 1
modality: image
input: text: Based on the provided empty room scene, please place the following three items side-by-side horizontally within the main space of the room: a glass shower door, a sink, and a toilet. Ensure there is some space between them so they do not overlap or block each other.
output: evaluation_points: 1. The image must clearly contain one instance each of a glass shower door, a sink, and a toilet.

2. All three items must be arranged horizontally (left-to-right), not stacked or placed in a front-to-back line.

3. All other background elements must remain consistent with the original empty room reference image.

4. The image should clearly appear to be a modification of the reference image by adding objects, not a completely newly generated room.

turn: 2
modality: text
input: Observe the image generated in the previous turn. Among the three newly added items, which one is positioned in the middle?
Options:
A. Glass shower door
B. Sink
C. Toilet
D. None of the items are in the middle
E. None of the above.
output: answer: <DYNAMIC>

turn: 3
modality: image
input: Please remove the tallest item from the three newly added items in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest item (the glass shower door) must be removed, leaving that area blank or showing the background.

2. The positions and appearances of the two remaining items (sink and toilet) must not change.

The background and unrelated elements must match the Turn 1 input image (the empty room scene).

4. The image should clearly appear to be a modification of the reference image, not a completely new image.

turn: 4
modality: image
input: Based on the image from the previous turn, reposition the two remaining items so they are strictly aligned along a single vertical (front-to-back) line. Place the shorter item in front and the taller item behind it, creating a correct visual occlusion relationship where the front item partially blocks the view of the back item. Keep all other environmental elements unchanged. Please generate the adjusted room layout.
output: evaluation_points: 1. The image should contain only the two remaining items; the removed item (glass shower door) must not reappear.

2. The two items must be strictly aligned along a single front-to-back axis, not offset left or right.

3. The shorter item (sink) must be placed in front, and the taller item (toilet) must be placed behind it.

4. The front item must visually occlude part of the back item, establishing a clear foreground/background relationship.

5. The items' styles and sizes must remain unchanged; only their positions and front/back relationship should be altered.

The room background must match the Turn 1 input image (the empty room scene), and the image should appear as a continuous modification from previous steps.
