## Executive Summary
Zone setting changes used to rebuild entire DNS zones, even ones with tens of millions of records.

## Why It Matters (Strategic Analysis)
Full zone rebuilds triggered by minor configuration changes scale poorly as domain record counts grow, causing memory saturation on large enterprise zones. Replacing monolithic rebuilds with delta-based build planning decouples edge propagation delay from domain scale while preventing stale DNS state propagation.
