# The loop itself, kept separate from round.yml so the loop bounds (which encode the
# RESUME logic) are readable in one place.
#
# RESUMABLE. Rounds are numbered from the on-node ledger, not counted from zero, so a
# re-run after an interruption continues where it stopped and can never lose or duplicate
# an earlier round. Already at or past the target count => nothing to do, and the run
# collapses to a harvest.
#
# NOT AUTHORISED => NO REBOOTS. memattr_survey_reboots_authorised defaults false, which
# makes the whole loop a no-op. Everything else (preflight, baseline probe, harvest,
# analysis) still runs, so a dry run exercises the entire pipeline without touching a
# single machine.
