Writing stock core/extra over the host /etc/pacman.conf raced with the tests workflow, which appends [cachyos]/[chaotic-aur] to the same file — runs 132 and 133 ran concurrently on the runner, so either job could corrupt the other's config mid-pacman. Use 'pacman --config $(mktemp)' with stock core/extra instead: same DNS-lookup reduction (only core/extra sync, no cachyos/chaotic), zero writes to shared state. Verified on the runner: exit 0, only core/extra synced, host /etc/pacman.conf mtime unchanged.
