"""
|
||||
MVP stage 3: media assets — медиа-активы + привязка атомов + публикации.
|
||||
|
||||
Сборка: atom (stat/claim) → video asset → atom_assets (таймкоды) →
|
||||
compositions (video) → publications (YouTube) + metrics.
|
||||
|
||||
Медиа-активы генерируются как видео-сценарий на основе atom_versions
|
||||
под youtube_script: каждый stat/claim → свой отрезок видео (таймкод).
|
||||
|
||||
Запуск:
|
||||
python3 stage3/media_assets.py --project rabota-ufa
|
||||
python3 stage3/media_assets.py --all
