# Run Recorrection

`POST /admin/assignments/{assignment_id}/run-recorrection`

Preview recorrection for submitted exercises in an assignment.
Reruns check_solution() on existing submissions without modifying the DB.

Without a body, every submission in the assignment is re-corrected. When
`scope` is provided, only the listed (session_id, exercise_id) pairs are
re-corrected, which keeps the request fast enough to avoid timing out.

## Request body

- RunRecorrectionRequest
  - `scope` RecorrectionScopeItem[], nullable
