Desktop FS.cp opened the target with io.open(target, "w") only as a writability probe: it never wrote through that handle, never closed it (leak), and "w" truncated the target before the source was even read. Removed the probe — FS.write already opens and reports errors. Also pass the path, not the boolean, to cannot_open.
