Photograph a written answer sheet. Objective answers are graded deterministically; subjective ones against a rubric, with every rubric point cited from your own writing.
SQ
Preview, not live.worker-ai has no answer-sheet grading endpoint yet, so the sheet below is the design’s worked example rather than one of yours. Everything else on this screen — the deterministic objective marking, the rubric with citations, the confidence threshold that routes an item to a human — is the intended behaviour.

Objective items are graded deterministically against the key. Subjective items are scored against a rubric with each rubric point cited from your own writing — anything under 0.7 confidence goes to a human before it counts.

A rubric point is only awarded when the grader can point at the line in your sheet that earns it. Points it cannot locate are not awarded silently — they are what pushes an item below the confidence threshold.
