# helper), which could surprise the user mid-work. So we only REPORT;
# findings land in this job's log and the operator runs
# `scrub.py --git-configs <path> --fix` deliberately. A non-zero exit
# (rc=1 = "credential found") must NOT mark the whole cron job failed —
# the report in the log is the signal.
