EVALUATION

2/5 partial

Mostly blank white canvas; only drag produces a faint sparse dye trail, no fluid swirl visible.

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.
