Builder extends the creational type-integrity story from type selection and instance control to construction complexity: beyond Factory Method governing which types enter the system and Singleton governing how many instances exist (both validated by LSP), Builder ensures that multi-step construction of complex objects also produces well-formed products through its Director-Builder protocol — completing the type-integrity guarantee across all three creational concerns.
builder-completes-creational-spectrum is an orphaned depth-3 conclusion with no upward connections; combining it with the type-integrity claim integrates Builder's unique concern (construction complexity) into the lifecycle governance story
