Ratings captured 2026-08-01 from the live leaderboard dated August 1, 2026. The July snapshot remains preserved separately; this file records the current refresh and the models newly added to the chart.",
    "method_note": "The chart keeps one capability score per model and applies the current refresh to the latest scene. Historical snapshots remain release-date scenes; Arena ratings drift as the field grows, so this is a transparent teaching simplification rather than a re-estimation of past leaderboards."
