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 Christmas tree, a gift box, and a rocking horse. 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 of each of the three specified furniture items: a Christmas tree, a gift box, and a rocking horse.

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

3. All other background elements must match the original empty room reference image.

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

turn: 3
modality: image

output: evaluation_points: 1. The visually tallest furniture item (the Christmas tree) must be removed, leaving that area blank or showing the background.

2. The positions and appearances of the remaining two furniture items (gift box and rocking horse) must remain unchanged.

The background and all unrelated elements must match the Turn 1 input image.

The image must appear to be a modification of the Turn 1 input image, not a completely new image.

turn: 4
modality: image
input: Based on the image generated in the previous turn, rearrange the two remaining furniture items so they are aligned strictly along a single vertical (front-to-back) line. 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 back 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 furniture items (gift box and rocking horse); the removed item (Christmas tree) must not reappear.

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

3. The shorter item (gift box) must be placed in front, and the taller item (rocking horse) 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 style and size of the furniture items must remain unchanged; only their positions and depth relationship should be altered.

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