Finally I learned by accident what I had been missing, and what I think should be added to the docs: Sublevels need to be in the same directory as their parent level, or in a descendant under that directory. As far as I can tell, that’s not mentioned in the docs, and the online tutorials seem to take it for granted that everyone knows this.

In the first paragraph of the world composition documentation, while it doesn’t explicitly say “all sublevels need to be in the same folder as the persistent level”, it does say it scans the folder of the persistent level to find all other levels:
The persistent level does not store any streaming information and instead scans a folder and treats all found levels as streaming levels. Each streaming level has information stored in the package header, which World Composition can read without loading the level into memory.
