"""Flow komposit end-to-end via /lesson-progress.

Skenario utama:
- Lesson dengan BOTH exercise (tab c) DAN quiz → exercise + quiz 3/4
  → composite 92.5 (> 75) → state='done';
- exercise saja tanpa quiz → state='in_progress' (composite 70 < 75) → belum done;
- quiz 0/4 setelah exercise → composite 70 < 75 → state='in_progress'.

Lesson dibuat via marker markdown (---INITIAL_CODE--- untuk tab c, dan
---INITIAL_QUIZ--- untuk tab quiz) supaya _lesson_components() di route
mendeteksi has_exercise=True dan has_quiz=True.

Integrasi PostgreSQL (butuh DATABASE_URL).
