Plan a production workflow for снять и смонтировать рекламный ролик на 15 секунд. For each step: what is produced, what is checked before moving on, and what fails if the check does not pass. Rules: lock the brief before generating; lock assets and their roles before the first paid call; state the expected credit cost before the expensive step; never invent job results or balances; if a check fails, stop and report instead of guessing.
