Before that, the rustup installer failed with 'mktemp: mkdtemp failed on /var/folders/.../T/tmp.7vU2Nd7lzV: Operation not permitted' / 'error: command failed: mktemp -d' (sandboxed temp dir), so it fell back to micromamba. No venv, simulator build, patch, harness test or validate step ran. I did not adapt setup to macOS because the brief requires Linux x86_64 and engine float/libm results may differ by platform."
