Build a Conway's Game of Life explorer
Build a Conway's Game of Life explorer as a static page in this directory: index.html, style.css, life.js. Canvas grid with play/pause/step/clear, speed slider, drag-to-draw cells, a library of classic patterns (glider, glider gun, pulsar) placeable by click, wrap-around edges toggle, generation counter, dark theme, and tests.html + tests.js exercising the next-generation rules. Run the tests headless with 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.

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.
