Sets the syllabus, the rubrics and the conventions each half of the course runs on. Confirms and releases every grade, and is the only person who can override one.

Run the problem-solving sessions, review draft feedback against the rubric, and release grades where the instructor has delegated that. Named here once the roster is settled.

Builds and operates this site and the grading service, and hands both over to the instructor at the end of the semester with the keys rotated and the runbooks written.
