# output holding a COPY of the whole application tree plus the wheels and vendor
# installers. It is gitignored, but this sync walks the WORKING TREE rather than
# git, so it came through anyway - and its copies of config.py and
# requirements.txt then tripped the scrub gate. Anything else generated into the
# working tree needs excluding here too, for the same reason.
# rsync --exclude also PROTECTS a path from --delete, so anything that reached
# the publication tree before its exclude existed stays there forever, invisible
# to the sync and caught only by the scrub gate. Purge the generated paths first
# so adding an exclude is enough on its own.
