The concurrent access test validates the class's claim of being thread-safe by running 4 worker threads simultaneously calling get_available() and done(). This is critical for verifying the intended use case of multi-threaded build processing. The empty graph test ensures proper error handling when the sorter is initialized without any nodes.
