I accepted the IU_0048 candidate and wrote the verdict to artifacts/review.json. It passes every technical check, but the bear is only a weak match.

Checked directly:

• Hash: the downloaded file's sha256 matches 1d6a0b72…c008.
• Pixel art: I decoded the PNG with a small Python script (Pillow wasn't available). It is 512×512 and every 16×16 block is one solid colour, so it's a true 32×32 grid with hard edges and no anti-aliasing or gradients.
• Palette: it uses exactly 8 colours, all from the allowed list: background #0c1610, black outline, lagoon, moss, phosphor, navy, cobalt and bone.
• Content: I found no text, watermark, frame or border. There is one front-facing bust, centred, with shoulders reaching the bottom edge.

My judgement from viewing the image:

• Skin: lagoon, clearly.
• Eyes: dots, two 2×2 black squares.
• Headgear: a moss beanie with a folded cuff and phosphor stripes. It could also be read as a cap or helmet.
• Outfit: a navy jacket with cobalt collar, a bone zip line and a chest pocket.
• Bear: this is the weak trait. The round ears sit on the sides of the head under the hat, and with the dark muzzle the face reads somewhat like a monkey. The two bone-coloured cross marks in the muzzle are also unclear; they could be taken for teeth, a nose or a second pair of eyes.

Scores: brief 6, silhouette 7, style 9, originality 6. Name: "Lagoon Cub".

I accepted because no trait is clearly missing, which is the rejection rule. A stricter reviewer could reasonably reject over the bear species alone. That call is my judgement, not something the pixel check can settle.

The output file is untracked, and I didn't add the image to the repo.
