# opencode · Fusion router

opencode on Fusion has no image input, so it self-critiqued from SVG geometry instead of the render.

### Self-score vs judge, by axis

Best round v2, 0–10 per axis

agent self-scoreexternal judge

**Judge:** A clean, cohesive flat illustration. The pelican reads well from its long orange bill, throat pouch and S-curved neck, and the wing reaches the handlebar while the legs go to the pedals. Defects: the body is an egg-like blob with a detached tail wedge, the neck floats loosely off the body, the seat is missing or hidden, and the frame geometry is slightly odd, with a thin, oversized pouch outline.

### Score by round

Out of 40. Each round starts from the previous round's best SVG.

self-scorejudge

This lineage had no image input, so its self-scores come from reading SVG geometry rather than the render.
