Migration 000062 adds lessons.publish_status (DRAFT default for new rows; existing rows published). Editors see all lessons; learners see published-only lists and GET by id. Sequential prerequisites and completion counts ignore drafts. Course lesson_count counts published lessons only. Swagger documents publish_status on create/update bodies.
