# f1d A/B: does the ruin-and-recreate LNS move (un-divide one wing of a
# storey, rebuild it with the adjacency-aware constructor seeded from the
# surviving circulation bordering the wing) reduce the fail count relative
# to the current baseline (small local mutation operators only)? Same qpk
# protocol as 8sh/qi6: equal-budget ON vs OFF, both arms finished with the
# standard finish-time --collapse (94g) so the comparison is apples-to-apples
# on the final collapsed score.
#
# Authoritative metrics: total fail count read from the .fails file
# homemaker-fitness writes. Each run appends one TSV row so partial results
# survive an interrupt.
#
# Usage: experiments/run_f1d_ab.sh
