The four rules, the derived target set and the deletion of orphaned reports are
built and checked as far as they can be without the host. What remains is a
deploy, and the first three items of its checklist are numbers already known by

Slice 4 records the more useful failure. Its test first rebuilt the loop instead
of loading it, which would have stayed green while the shipped file was broken.
Loading the real function exposed within a single run that the script set its
paths unconditionally and ignored the environment.
