I accepted the candidate for IU_0132 and wrote the review to artifacts/review.json. The file is valid JSON and is left untracked for upload.

• File check: I downloaded the image to /tmp, outside the repo. Its sha256 matches the expected value (0510b91c…6d25).
• Traits: I looked at the image directly. It shows a steel-grey bear with round ears, a single green cyclops eye, a moss-green ribbed beanie, and a navy suit with a white collar and phosphor-green tie. All five required traits are present.
• Style: The pixels are crisp and square on what looks like a 32×32 grid, with thick black outlines, the dark green background, and colours that look like they come from the allowed palette. There is no text, watermark or border, and only one character, shown as a centred bust with shoulders at the bottom edge.
• Scores: brief 8, silhouette 9, style 9, originality 7. Name: "Steel Cub".
• Uncertainty: Brief got an 8 because the beanie has a wide brim and reads a little like a bucket hat. That is my judgement call, not something I measured. I also checked the palette by eye, not pixel by pixel.

I did not write a README. The task said to write only the JSON file, which overrode the reference's suggestion to add one.
