The machine config on vm4006 lost its legacy branches block, renamed
builds.master to builds.nightly and moved build/libs into the default
definition's artifactDirs. Step 18 still described that work as pending
and named a rollback path to 0.9.18 that the file no longer supports.
What is left there is the shrinking to genuinely host-specific keys,
plus the open question where the nightly rebuild belongs once master
carries its own config.
