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 fuel dispenser, a fire extinguisher cabinet, and a bollard. 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 fuel dispenser, a fire extinguisher cabinet, and a bollard.

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 provided empty room reference image.

4. The image must appear to be a modification of the reference image (e.g., objects added to an existing scene) rather than 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. Fuel dispenser
B. Fire extinguisher cabinet
C. Bollard
D. None of the three items
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 fuel dispenser) must be removed, leaving that area blank or revealing the background.

2. The position and appearance of the two remaining items (fire extinguisher cabinet and bollard) must not change.

The background and all unrelated elements must remain consistent with the Turn 1 input image.

4. The image must appear to be a modification of the previous scene, 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 rear item. Keep all other environmental elements unchanged. Please generate the adjusted room layout.
output: evaluation_points: 1. The image must contain only the two remaining items (fire extinguisher cabinet and bollard). The removed fuel dispenser 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 (bollard) must be placed in front, and the taller item (fire extinguisher cabinet) must be placed behind it.

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

5. The style and size of the items must remain unchanged; only their position and front/back relationship should be altered.

The room background must remain consistent with the Turn 1 input image, and the image should appear as a continuous modification from the previous steps.
