The docs for a basic roll-over seem to be lacking a bit around how the index write alias is managed. Does it have to exist on the index or will ISM add it? When an index “Rolls over” for various conditions, does the new index automatically get the alias and the previous index has the alias removed…

One more thing to add:
the index template does not automatically set the index alias:
