Change log

For instructors. Every action that can affect a grade or who is in the course is recorded, so a dispute or a mistake can be traced.

The change log is not part of the daily navigation; it is linked from the roster page and from each student's history page. It lists, newest first:

Recorded action	What the entry shows
Score saved or changed	who, when, the total before and after, whether it was released, the reason if one was given
Roster import applied	counts added, dropped, moved, and the NetIDs
Teaching staff added or changed	NetID, role, sections
Assignment created or its settings changed	the settings before and after
Assignment version published	version number and question ids
Canvas export	which assignments
Submission re-queued for grading	student and question

Entries are append-only. Filter by NetID, entity, action, or reason.

Platform administrators have their own log of platform-level events (courses, offerings, staff, publishes, imports, exports). It deliberately excludes score changes: administrators do not see student work. If an administrator needs a course's grade history, they add themselves as an instructor of that offering, and that action is itself logged.
