Question 9
AI reconstruction (instruction): Discuss the missing pattern and the pictured candidates. Added conditions: classify the white cutouts into three families: two opposite solid sectors, two curved strips, and four petal-like openings. Rotated versions count as the same family. Require each family once in every row and column. Identify all pictured candidates that satisfy this family rule, and explain whether it fixes their orientation. This is an open-ended self-review task.
