  title: Canvas LMS Publish Assignment and List Submissions
  summary: Publish a draft assignment, then list every submission for it.
  description: >-
    A grading-prep flow for Canvas. The workflow publishes (or re-saves) an
    existing assignment so it becomes visible to students, confirms the published
    state by reading the assignment back, and then lists every submission for the
    assignment so a grader can begin marking work. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
