- CREATE TYPE task_status ENUM (todo, in_progress, in_review, done) - CREATE TABLE tasks with tablo_id FK, position, status columns - DROP order: table before type in Down migration (Pitfall 3) - sqlc queries: ListTasksByTablo, InsertTask, GetTaskByID, UpdateTask, DeleteTask, MaxPositionByTabloAndStatus - migration applied cleanly, sqlc generate produces TaskStatus type and Task struct
