Domain: Paper_Crafting / origami_sequential_logic

turn: 1
modality: image
input: Generate a square sheet of origami paper lying flat on a table, face-up, with its four edges perfectly horizontal or vertical. The front side of the paper is off-white, and the back side is black.
output: evaluation_points: 1. The image shows a standard square sheet of paper at its center.

2. The visible side of the paper is a solid, off-white color.

3. The paper is perfectly flat with no visible creases.

4. All four edges of the paper are aligned horizontally or vertically, not at an angle.

5. The background is a simple table texture that contrasts with the paper's color.

turn: 2
modality: text
input: Without lifting the paper from the table, perform a single 'valley fold' along its horizontal centerline. After completing this fold, what color of the paper's surface should be visible to the camera?

Options:
A. Off-white
B. Black
C. A mix of off-white and black
D. Colorless
E. None of the above.
output: answer: B

turn: 3
modality: image
input: Based on the rectangular state from the previous fold, and without flipping the paper over, perform another 'valley fold' along the current vertical centerline. Generate the final result after completing these two folds.
output: evaluation_points: 1. The paper's overall outline is now a square (one-quarter of the original area).

2. The visible surface color is black (the back side color).

The background and table texture are identical to those in the Turn 1 output image.

turn: 4
modality: image
input: Now, completely unfold the paper back to the flat, face-up state from Turn 1. Generate how the paper looks now, focusing on the details of the crease pattern.
output: evaluation_points: 1. The paper has returned to its large square outline, with dimensions essentially matching Turn 1.

2. The color has returned to off-white.

3. The paper surface must show two clear, perpendicular creases (a cross shape) intersecting at the paper's center point.

4. Among the four short crease segments formed by the cross, the bottom segment must be a valley crease (appearing as a groove or line receding into the paper).

The background and table texture are identical to those in the Turn 1 output image.

turn: 5
modality: text
input: According to origami theory, after performing the two 'valley folds' described and then unfolding (with the front side up), the paper should have four crease segments meeting at a common endpoint. From the current camera's perspective, what should the properties of these four crease segments be? (Note: A 'mountain fold' means the crease ridge protrudes toward the viewer; a 'valley fold' means the crease dips into the paper).

Options:
A. 4 valley creases
B. 2 mountain creases and 2 valley creases
C. 1 mountain crease and 3 valley creases
D. 3 mountain creases and 1 valley crease
E. None of the above.
output: answer: C

turn: 6
modality: text
input: Please carefully observe the unfolded image you actually generated in Turn 4. How many 'mountain creases' (i.e., creases that appear as raised ridges) are actually depicted in that image?

Options:
A. 0
B. 1
C. 2
D. 3
E. None of the above.
output: answer: <DYNAMIC>
