# Run from the repo root AFTER the round posts DONE. It pulls, checks the
# encoding, banks UTF-8 copies under logs/, and reduces every cell.
#
# IT CHECKS THE LEG COUNTS FIRST AND REFUSES ON A ZERO. That is not ceremony:
# the lane that held this box before this one posted a completion NOTE - in
# wording its driver generates automatically - over a sitting that ran ZERO
# legs, and the identical wording had covered a real round four hours earlier.
# A DONE line proves the ladder loop exited. The leg count is the thing that
# proves it measured. Read the count, not the word.
