- Add NOT NULL constraints to soundtrack.uuid, song.uuid, and song.soundtrack_uuid - Add corresponding DROP NOT NULL in down migration - Update header comments to reflect combined Phase 1 & 2 This eliminates the need for a separate migration 000007 while maintaining proper rollback capability. The NOT NULL constraints are added AFTER all UUID backfills are complete, ensuring data integrity. Generated by Mistral Vibe. Co-Authored-By: Mistral Vibe <vibe@mistral.ai>
