The repo was fetched at commit 6b6921f8d463314aa7c96234e1be25a25245f704 as a GitHub tarball, because the sandbox blocked writing .git/config inside the workspace so git clone failed. Setup then stopped at its first uv call. The CH sanity check, the STACK hash check, the CMA-ES search and all seed blocks (560000..560063, 561000..561255, 570000..570511, 5028000..5030000) were not run or touched, so the confirm block is still fresh. To run this item, send it to a Linux x86_64 worker as the setup expects."
