Research direction
Start by reproducing the uu-cp -sr a b and gnu-cp -sr a b commands from the issue, including the symlink setup. Trace the cp command entry point and its recursive directory and symlink handling; done means matching GNU cp by reporting the error while still copying the directory into b/a.
