The handler fixtures for a collection movie and a searched movie both carried tmdb_id 1234 and the title Test, so the two branches of build_add_movie_body were value equivalent. The builder test also populated only the table its branch needed, so swapping the branches was caught by an unwrap panic on the empty table rather than by any assertion on the values.
The searched movie fixture now has its own identity, and the builder test seeds both tables so the branch is chosen against real competing data. Swapping the branches now fails with a value diff naming the wrong tmdb_id and title.
Only the handler copy of the fixture is changed. The network copy deliberately shares tmdb_id 1234 with the movie fixture, which is what drives the already in library marker in the add movie snapshots, so changing it there would have silently removed that marker.
