Build a paint / drawing app
Build a paint / drawing web app as a single page in this directory: index.html, style.css, paint.js (vanilla JS, no deps, HTML canvas). Freehand brush with adjustable size and color, a color palette plus a custom color picker, an eraser, a clear-canvas button, undo/redo, and a "save as PNG" download. Show the current brush preview. Polished dark theme, responsive canvas. Make it feel good to draw on.
3 sessions from the same published task, on one clock. Scrub to any moment and compare what existed, or open a pane to read its full trajectory.

Token and context figures come from the harness's own per-turn reporting; sessions captured before telemetry landed show a dash. Reasoning marked ~ is estimated from the transcript's thinking text where the harness doesn't report it separately.
Verdict
Pairwise picks on the outputs above, from the current Arena tally.
What voters said they were judging
Arena picks do not collect a reason or judging criterion, so no qualitative verdict is inferred here. The bars report only the current comparison tally.
