Status: OUT
The GoF's infrastructure-backed lifecycle variation is safely scalable — extending from fine-grained objects to application-level architecture — only when the transparency-safety tradeoff in recursive structures is resolved toward safety, since Composite trees form a critical layer of the spatiotemporal infrastructure.
Depth-8 — Composite trees are load-bearing infrastructure for the spatiotemporal substrate; if their transparency-safety tradeoff is unresolved, the infrastructure cannot guarantee safe scalability for lifecycle variation
