I accepted the candidate for IU_0040 and wrote the verdict to artifacts/review.json. I judged it by viewing the downloaded PNG. I did not decode the pixels or count the grid, so the 32 x 32 grid and palette are judged by eye.

• Integrity: the downloaded file's SHA-256 matches the expected hash. It is a 512 x 512 PNG, which is consistent with a 32 x 32 grid upscaled 16x.
• Traits: all five are present. It is a tangerine cat with pointed ears and big white eyes, wearing a navy peaked cap and a navy suit with lapels and a gold tie.
• Style: the pixels are square and hard-edged, with a thick black outline. The background is solid dark with a few tiny green specks. There is no text or watermark, and it is a single centered bust.
• Scores: brief 9, silhouette 8, style 9, originality 7. The originality score is a judgment call. The character reads as a cat in uniform rather than a template, but it isn't especially unusual.
• Name: "Captain Whisker".

I did not add the image to the repo. The review file is untracked.
