Build a personal finance dashboard
Build a personal finance dashboard as a static web app in this directory: index.html, style.css, app.js, data.js, charts.js. Transactions table with add/edit/delete + localStorage, monthly budget bars, a canvas spending-over-time chart, category filters, CSV import/export, dark theme, keyboard shortcuts, and a self-test page (tests.html) that exercises the core logic. Run your tests with a headless check (node) and fix what fails.
4 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.
