This technical note presents a Tier-7 domain instantiation of the closed versus distributed recursion principle formalised at Tier-6 within the Paton System. It demonstrates that numerical stability theory exhibits the same structural distinction: closed recursion under sustained amplification leads to boundary collision, while distributed constraint mechanisms preserve bounded continuation. No new operators are introduced, and the foundational admissibility spine (Gate → Datum → ℘) remains unchanged. The document functions as a domain overlay illustrating structural invariance across abstract and engineering systems.
Andrew John Paton (Fri,) studied this question.
