Builder's Director/ConcreteBuilder separation exemplifies SRP in the creational domain (construction algorithm and representation assembly serve distinct actors), and its position at the minimally-coupled extreme of the creational spectrum suggests a relationship between product coupling and responsibility distribution — Builder's minimal coupling to product internals naturally separates responsibilities that Prototype's maximal coupling (Clone must replicate full state) concentrates, though the precise nature of how SRP pressure varies across the full spectrum is not established by these two endpoints alone.
SRP validation in Builder's minimally-coupled context illuminates how product coupling constrains responsibility separation across the creational spectrum
