How are the images checked?
Every image is checked the same way by Claude Sonnet 5.5, whose maker has no image model here: it first writes out all the writing it can read, without being told what should be there, then answers each question yes or no from the image. An image passes when all its writing is there and every answer is yes. Nothing else is judged.
