- migration: open question type, rubric, max_length, quiz grader and
the grading and review columns of attempt answers
- open answers are checked, stored as pending and never scored on
answer; a changed text resets the grading state
- student JSON gains text, grading_status, grader_feedback,
review_comment, max_length, needs_review and open_answers; the
rubric is never serialized
- quizzes_create_question, update_question, delete_question and
reorder_questions on /api/v1/quizzes/{slug}/questions
- update_question replaces answers by id (kept, created, deleted), so
answer ids stored in past attempts stay valid; foreign ids are refused
- classes.CheckQuestion holds the importer's per-question rules, shared
with the manage routes; attempt scores are never touched (D-16)
- Service.Start resumes an open test attempt, closes expired ones at
their deadline and refuses a start past max_attempts under an
advisory lock; StartAttempt stays as a wrapper
- answers to a test are accepted until the deadline plus
golem15.quizzes.test.grace_seconds; one_way answers are final
- a test covers the whole quiz and keeps a stable per-attempt order
- 409 bodies carry a code; list and attempt rows carry attempts_left,
question_types and seconds_left; import accepts the test keys
