I'm rejecting the candidate for slot IU_0008, because it doesn't clearly read as a BOT. The verdict is written to artifacts/review.json. The JSON parses, and the reason (271 chars) and name (12 chars) are within the limits.

What the file shows (checked with code):

• The downloaded file's sha256 matches 3f8c4cfa…99ae.
• It is a 512×512 PNG, which is exactly a 32×32 grid of 16 px blocks. Every block is one solid colour, so there's no anti-aliasing, gradient or blur.
• It uses only 8 colours: background #0c1610, black outline, and six palette colours (tangerine, cobalt, navy, bone, rust, gold). Nothing is off-palette.

What I saw looking at the image (my judgement):

• Rules met: one centered front-facing bust with the shoulders reaching the bottom edge, thick black outlines, no text, watermark or frame.
• Traits present:
  • Tangerine skin: the face and shoulders are #f0a04c.
  • Big eyes: large bone-white eyes with black pupils.
  • Cap: cobalt top with a navy brim.
  • Overalls: cobalt overalls with gold buckles.
• Trait missing (BOT): the character reads as a human plumber or mechanic, with side ears and bare skin shoulders. There's no antenna, visor, screen face or panel seams. The only possible robot cues are rust dots on the shoulders and the sides of the head, which could be rivets or bolts but are weak.

Scores: brief 5, silhouette 8, style 9, originality 6. Name: "Tango Wrench".

Uncertainty: the BOT call is a judgement and the deciding factor. If the rust dots count as rivets and that's enough for the BOT trait, the verdict would flip to ACCEPT, since nothing else fails.

I didn't add the image or a README to the repo. The task said to write only the JSON, so I skipped the README the background reference suggests. artifacts/review.json is left untracked for the daemon to upload.
