A one-item-at-a-time human labeling queue — number-key label buttons, skip and flag escapes, a resumable "34 / 200" progress bar, undo for the last call, an all-done screen, and a one-shot lock per item so a double press can never double-label.
npx shadcn@latest add @zyeon/labeling-queueZyeon UI limits how often it can be asked, and Labeling Queue hasn't had its turn. Its source will show here once it has.
