Fitur B — setiap jenis soal kini punya key sendiri sehingga model
penilaiannya eksplisit, tidak ditebak dari isi konten:
- ---QUIZ_MCQ--- pilihan ganda biner (tepat satu [x]; larang [N])
- ---QUIZ_WEIGHTED--- pilihan ganda berbobot ([N] >= 1, minimal satu [ ],
bobot tertinggi unik = kunci; poin parsial)
- ---FLASHCARD--- kartu hafalan tanpa penilaian (larang opsi)
- legacy ---QUIZ_FLASHCARD--- / ---INITIAL_QUIZ--- tetap dibaca tanpa
perubahan perilaku (regex opsi legacy sengaja tidak berubah — baris
'- [10]' di konten lama BUKAN opsi); dihapus dari docs/template
- ::diagnostic tetap kategori di dalam QUIZ_MCQ & tetap masuk skor resmi
Model skor: rata-rata persentase per jenis yang ada, Math.round,
lulus >= 75. statusString: "X/Y" bila hanya MCQ/legacy, "P/100" bila ada
weighted, "completed" bila hanya flashcard (auto-lulus). Satu sesi/
attempt untuk semua jenis; soal flat urut dokumen.
Parser (backend & frontend mirror, ekstraksi multi-blok per key urut
dokumen via loop marker-start paling awal; id q-N deterministik):
- lesson_service.py: regex [ xX]?[0-9]* utk key baru, _iter_option_lines
kind-aware, _validate_quiz_options per kind, _parse_flashcards(kind,
id_offset), _extract_quiz_sections + guard loop maju (marker end
hilang tidak lagi infinite loop), get_lesson_quiz_total -> 100 bila
ada weighted (round-trip CSV "P/100")
- parseFlashcards.ts / index.ts / detectActiveTabs.ts / extractSections.ts:
mirror perilaku; heading soal <h3> kini fence-aware (fix fixture stale)
Payload attempt baru: quiz_type, earned_points, question_max_points —
opsional di validasi backend supaya klien lama tetap diterima; poin
di-recompute dari konten saat resume/review.
UI: QuizTab skor via statusString + alert berbasis percent, badge
weighted (✓ 10 / 🟡 7/10 / ✗ 0) di review, preview guru badge bobot +
"Berbobot (total N)", laporan guru badge MCQ/Bobot + tooltip, CSV
progress 2 kolom baru per lesson (_quiz_mcq, _quiz_weighted), template
editor konten QUIZ_MCQ/Quiz Bobot/Flashcard.
Tooling & docs: scripts/convert_quiz_keys.py (konversi legacy -> key
baru per run jenis, idempoten, verifikasi parse identik; examples/
content dikonversi), scanner mendukung semua key, docs/07 ditulis ulang,
docs/15 direvisi ke desain final, README/documentation/docs 02/04/09
diperbarui.
Tes: backend 444 lulus (+33: validasi ketat per key, urutan dokumen,
multi-blok, zero regression, field selalu di-emit), frontend 249 lulus
(+13 parser key baru, +11 model skor), parity fixture diregenerasi,
svelte-check 0 error, vite build OK.
Kebijakan termination tetap strict, tapi guru pegang override untuk kendala
tak terduga (false-positive blur dari dialog OS, browser crash, refresh
tak sengaja). Selain reset (siswa mengulang dari nol), guru kini bisa
memberi izin resume — siswa melanjutkan dari jawaban yang sudah tersimpan.
- Tambah kolom quiz_attempts.resumed_at (migrasi 0006) sebagai penanda izin
guru melanjutkan attempt terminated
- Tambah endpoint teacher-only POST /resume-quiz-attempt — kontrak keamanan
sama dengan /reset-progress (guru cukup student_id anonim, tanpa token siswa)
- Syarat: hanya attempt ber-status terminated yang bisa di-resume; submitted
ditolak karena kuis sudah selesai normal
- has_quiz_attempt meloloskan attempt ber-izin sehingga gate one-attempt
terbuka selama sesi lanjutan
- finalize_quiz_attempt menimpa row attempt sekali (status/skor/answers baru)
lalu clear resumed_at; retry berikutnya kembali ke jalur idempotent normal
- Sinyal ke frontend siswa lewat quiz_resumable pada data lesson; laporan guru
menampilkan badge "Dilanjutkan" dan tombol "Lanjutkan" untuk attempt
terminated
- Frontend: restoreQuizSession() merekonstruksi sesi dari jawaban tersimpan per
question_id, is_correct dihitung ulang dari source sebagai guard bila
konten soal berubah; option_id tak dikenal dianggap belum dijawab
- Frontend: firstUnansweredIndex() menentukan soal awal sesi lanjutan;
resolveQuizTabView() memusatkan keputusan view agar transisi resume dapat
diuji Vitest
- UI siswa: panel "Lanjutkan Kuis" + snackbar mode lanjutan (sekali muncul).
Attempt di-refetch segar sebelum sesi dimulai agar izin yang sudah dicabut
guru tidak memulai sesi yang jawabannya akan terbuang
- Test: 16 integrasi backend (services/tests/test_resume_quiz.py), 9 unit
quiz-session, 10 unit quiz-view
- Docs: alur resume + keterbatasan di 12-quiz-integrity.md, ringkasan di
07-quiz-authoring.md, kontrak endpoint di 02-backend-flask.md
- Only show celebration overlay and top bar completed checkmark if quiz score meets 75% threshold (>= 0.75) and exercises are done
- Return is_done, state, and composite_percent in POST /lesson-progress for exercise and quiz submissions
- Synchronize frontend LessonManager state with authoritative server is_done response
- Add has_quiz_attempt check in routes/lessons.py and token_service to recognize existing attempts even when composite state is in_progress
- Update QuizTab to display persistent attempt review, score status, and explanation instead of retake prompt on page load/refresh
- Make QuizQuestionView finish handler async, await finishQuiz(), and disable submission buttons to prevent navigation race conditions
- Update local ordered_lessons completion state dynamically upon passing
- Add unit and integration tests covering response payload attributes and has_quiz_attempt API field
- Bump APP_VERSION to 30
- Integrate diagnostic and evaluation MCQ scoring in quiz sessions
- Extend round-trip CSV grammar with `done:<ex>:<earned>/<total>` and `RESET`
- Fix completed count aggregation in repositories to include 'done' state
- Update progress report CSV export to output composite scores per lesson
- Add comprehensive test coverage for scoring, CSV round-trip, and exports
