EVALUATION

2/5 partial

Double pendulum swings with correct physics-like motion but no visible fading trail, just a faint arc, and no color.

Vision grade · anthropic/claude-sonnet-5

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
