I've accepted slot IU_0074 and written the verdict to artifacts/review.json. The file is valid JSON and is not tracked by git.

Checked directly

• Hash: I downloaded the image from the public URL and its sha256 matches c80a8d6f…4e73. Writing to /tmp failed, so the file went into test/scratch/ instead, which is outside the submission.

• Pixel grid: The image is a 512×512 PNG. Decoding it shows all 1,024 blocks of 16×16 pixels are each a single solid colour. So it really is a 32×32 grid upscaled with hard edges, with no anti-aliasing, gradients or blur.

• Palette: There are exactly 6 colours:

  • background #0c1610
  • outline black
  • steel #8a8f96
  • navy #2b3a6b
  • gold #e8c548
  • bone #f2efe6

  Black is the outline colour the rules require; the other four are all from the allowed list. The background is solid with no specks or scenery.

From looking at the image

• It's a single, centred, front-facing bust with the shoulders reaching the bottom edge, and a thick black outline throughout. There is no text, watermark or border.
• All the traits are present:
  • Skin: gold head.
  • Eyes: black shades with white glints.
  • Headgear: a steel hard-hat style helmet.
  • Outfit: a navy suit with a white collar and gold tie.

Judgement calls

• Species BOT is the weakest trait. The steel jaw plate with a slot and the bolt-like side nubs suggest a robot, but the face could also pass for a human in a hard hat. That's why brief got 7 rather than higher.
• Originality got 6. It's a fairly standard "foreman" archetype, but still a real character rather than a template.
• Final scores: brief 7, silhouette 8, style 9, originality 6, with the name "Foreman Bolt".

Open question: Whether this counts as clearly enough of a robot for the set is a subjective call that another reviewer might decide differently. I didn't add a README, because the task said to write only the JSON file.
