I wrote artifacts/review.json with an ACCEPT verdict for slot IU_0067 (name "Lilac Beacon"; brief 7, silhouette 8, style 9, originality 7). It's a narrow accept: the antenna is the weakest trait and I scored it down rather than rejecting. The JSON parses, and the reason (252 chars) and name (12 chars) are within the limits.

What I checked directly:

• Hash: the downloaded file's sha256 matches ee54526e…4f21. I couldn't write to /tmp, so I saved it to ~/tmpimg/ instead, which is still outside the repo.
• Format and pixel grid: it's a 512×512 PNG. When I sampled it in 16 px cells, every cell was a single flat colour, which fits a 32×32 grid scaled up with hard edges.
• Colours: the whole image uses exactly 9 colours: background #0c1610, black, lilac, cobalt, navy, bone, steel, phosphor and gold. All except black come from the allowed palette, and black is the required outline colour. There's no anti-aliasing, gradient or blur.
• Composition: there's one front-facing bust, centered, with the shoulders reaching the bottom edge. Black outlines surround every shape, and there's no scenery, text, frame or watermark.

Traits, from viewing the image and reading the decoded grid:

• Lilac skin: clearly present.
• Big eyes: clearly present, white with black pupils.
• Jacket: clearly present, with a cobalt collar over a navy body.
• Ghost: I'm reading the rounded lilac head and the drippy lower edge running into the collar as a ghost. Because it's only a bust there's no tail, so this is a judgement call.
• Antenna: this is the weak point. A steel headband with gold ear pieces sits on the head, and a phosphor-green bulb floats above it. One empty background row separates the bulb from the band, and there's no stalk. I counted it as an antenna tip, so the trait isn't missing, but a stricter reviewer could call the antenna absent and reject.

The verifier can't re-download the image without network access, so these findings rest on my own check.
