Status: OUT
The GoF's pedagogical onboarding (starter patterns sampling both behavioral subsystems within a proven reuse ecosystem, with restraint enabling incremental adoption) safely introduces practitioners to a fully governed system only while Composite's transparency-safety tradeoff does not undermine the recursive subsystem that the starter patterns include — since Composite is among the recommended starters, the transparency-safety tension is inherent in the onboarding experience itself.
Safe onboarding requires the Composite starter pattern's transparency-safety tradeoff not to undermine the recursive subsystem being introduced
