This is consistent with SOL-EXP-0016’s timeout and with the verified lower bound of seven baseline deletions from SOL-EXP-0017. Together LUNA-EXP-0015 and 0016 show two selected max-domain subsets at radius7/8 each had 9/10 available cells but constraints reduce their local maxima back to148. This validates the model on a concrete subcase but suggests baseline-neighborhood local repair alone is nearing a plateau.
