# leaf_share_factor sweep under the winning bal+share stack (erc.7 second half,
# DESIGN.md §13.5). The §13.5 synergy A/B fixed factor 3 (the §13.3 winner) and
# showed depth-balancing × leaf-sharing survives to convergence (harbor −21 %,
# non-overlapping). This sweep asks whether factor 3 is still the construction
# optimum once depth-balancing is stacked on top: does collapsing FEWER (factor
# 2) or MORE (factor 4) same-code rooms per shared leaf do better?
#
# Both knobs ON in every run (DEPTHBAL=1 LEAFSHARE=1); only LEAFSHAREFAC varies.
# factor 3 bal+share is already known from run_synergy_ab.sh (maple 82.3, harbor
# 40.0), so we only run 2 and 4 here. leaf_share_max (scoring cap, default 4)
# already covers all multiplicities at factor ≤4, so no missing-fail leak — the
# final native re-score (MISMATCH guard) verifies this per run.
