turn: 1
modality: image
input: text: Based on the provided empty room reference image, please place the following three pieces of furniture side-by-side horizontally within the main space of the room: a tall floor-to-ceiling bookshelf, a single-person beanbag chair, and a round low coffee table. 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 the three specified furniture items: a tall floor-to-ceiling bookshelf, a single-person beanbag chair, and a round low coffee table.

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

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

4. The image must clearly appear to be a modification of the reference image (e.g., by adding objects), not a completely newly generated room.

turn: 2
modality: text
input: Observe the image generated in the previous turn. Among these three newly added pieces of furniture, which one is positioned in the middle?

Options:
A. Tall floor-to-ceiling bookshelf
B. Single-person beanbag chair
C. Round low coffee table

E. None of the above.
output: answer: <DYNAMIC>

turn: 3
modality: image
input: Please remove the tallest piece of furniture from the three newly added in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest furniture item (the tall floor-to-ceiling bookshelf) must be removed, leaving its position empty or revealing the background.

2. The positions and appearances of the remaining two furniture items (the beanbag chair and coffee table) must not change.

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

The image must clearly appear to be a modification of the Turn 1 input image (by removing an object), not a completely newly generated scene.

turn: 4
modality: image
input: Based on the image generated in the previous turn, rearrange the two remaining pieces of furniture so they are aligned strictly along the same vertical (front-back) axis. Place the shorter furniture item in front and the taller one 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 should contain only the two remaining furniture items. The previously removed tall bookshelf must not reappear.

2. The two furniture items must be aligned strictly along the same front-back axis, not offset left or right.

3. The shorter furniture item (the round low coffee table) must be positioned in front, and the taller item (the single-person beanbag chair) must be positioned behind it.

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

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

The room background must remain consistent with the Turn 1 input image.
