I accepted the candidate for IU_0060 and wrote the verdict to artifacts/review.json. The JSON parses, the reason is 273 characters (limit 300) and the name is 10 (limit 18).

Verdict: ACCEPT. Name "Shade Monk". Scores: brief 8, silhouette 9, style 10, originality 7.

Measured facts:

• Checksum: the downloaded file's sha256 matches 26bde443…093ed. It's a 512×512 RGB PNG, saved to /tmp and not added to the repo.
• Pixel grid: every one of the 1024 blocks of 16×16 pixels is a single solid colour. So it's a true 32×32 grid scaled up with hard edges: no anti-aliasing, gradients or blur.
• Palette: there are exactly 7 colours, all allowed. The background is the required dark green #0c1610, outlines are #000000, and the rest are brick #df523e, navy #2b3a6b, bone #f2efe6, steel #8a8f96 and gold #e8c548.

What I saw in the image:

• One front-facing robot bust, centred, with the shoulders reaching the bottom edge.
• The head is brick red, with steel bolts at the ears and a slot mouth, so it reads as a BOT.
• It wears black wraparound shades and has nothing on its head.
• There's no text, watermark or frame.
• The outfit is a navy garment with a bone-coloured wrap collar or sash and gold trim. I read it as a ROBE.

Uncertainty: the outfit could also pass for a uniform jacket with a sash, which is why brief scored 8 rather than 10.

I also wrote artifacts/README.md, which sets out the question, the evidence and these limits. This is one reviewer's judgement and nobody else has checked it. Both files are left untracked, as required.
