- Add attempt lifecycle with per-attempt answer visibility (#336)
- Add atomic submission with updateMany CAS + $transaction (#337)
- Add iOS attempt-based question loading + local answer cache (#338)
- Freeze choice/fill/judge cross-platform contract with fill grading (#339)
- Add per-question-type learning analysis accuracyByQuestionType (#340)
- Add GATE E2E test suite with 17 scenarios (#341)
- CLEANUP-01: Remove illegal type → choice silent degradation
- CLEANUP-02: Integrate QuizQuestionType enum into iOS quiz views
- CLEANUP-03: Test verification, git delivery, targeted gate review
