Synergy A/B: bal+share vs share-alone, factor 3, seeds 0/1/2, staged 20k. maple 86.3->82.3 (-4.6%), harbor 50.7->40.0 (-21.1%, non-overlapping arms). Control reproduces §13.3. Adds run_synergy_ab.sh + run_sharefactor_sweep.sh (factor 2/4 sweep under bal+share, running). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# 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.
