EVALUATION

2/5 partial

2048 grid lacks visible gridlines/borders, no score shown; arrow keys move tiles but WASD unexpectedly also changes board despite 0% pixel diff claim.

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.
