Accuracy

How often does it match what really happened?

Every answer is checked against an outcome someone recorded for their own reasons: a pull request merged or closed, an issue labelled by a maintainer, a question closed by the community, an edit reverted, an article assessed.

Broken down by question type (yes/no, choice, score) and by track. Per-track numbers can only separate large gaps.
