### Self-score vs judge, by axis

Best round v1, 0–10 per axis

agent self-scoreexternal judge

**Judge:** The pelican is strong: a long orange bill with a large gradient pouch, a white body, and dark wingtips gripping the handlebar. The scene is attractive, with sky, sun, road and a lighthouse. The bicycle has odd geometry: a strange curved rear fender and stay, a chainguard that obscures the crank, and a seat hidden under the body. The legs reach the pedals but look awkward and stiff.

### Score by round

Out of 40. Each round starts from the previous round's best SVG. Dashed line: the 28/40 pass threshold.

self-scorejudgepass ≥ 28

Stopped after round 1. Two attempts failed on OpenRouter errors mid-run (8a7cebda: 502 provider\_unavailable; 6a4f0590: 504 upstream idle timeout), so per the benchmark rule (two infrastructure failures) the lineage was dropped.
