iter11/iter12/iter14 each hung nfs-server's `apt-get update` in TCP CLOSE_WAIT against apt-cache:3142 for 5-60 minutes, even with Pipeline-Depth=0 + No-Keep-Alive + Retries=3 + Timeout=30. Pulling once into the cache and fanning out to four nodes saves ~4 minutes of bootstrap when it works, but every run that hit the hang lost 20+ minutes — net negative. Remove the workflow cache restore step, the 02b_start_apt_cache.sh launcher, the apt.conf.d/01-cacher write in 05_bootstrap_nodes.sh, and the apt-cache cleanup in 17_cleanup.sh. Each node now talks directly to the upstream mirrors. Slower-but-reliable beats faster-but-stuck. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
