# Depth-balanced construction A/B (erc.4, DESIGN.md §13.4): does growing a

# localized the size fails to depth-driven maldistribution (same-target rooms at
|

# 0.05x..14.7x by slicing position); the §13.4 floor probe showed balancing

# collapses the depth spread (7->1) and the giant ratio (maxR 12.7->8.4 harbor,
