The permanence of structurally harmless defects is an equilibrium property, not a system failing: the same dual locking mechanisms that stabilize the quality profile (domain attractor + self-reinforcing incentive structure) also guarantee that frozen defects remain in their harmless state — preventing both remediation (which would require engineering investment the incentive structure discourages) and escalation (which would require cross-solution coupling the isolation architecture prevents).
One antecedent observes the paradox (permanent yet harmless), the other provides the mechanism (doubly locked profile); combining shows permanence-of-harmlessness as a consequence of the locking, not a coincidence
