This record presents a Tier-7 domain instantiation of the canonical recursive lifecycle within the Paton System. The paper demonstrates that healthcare and biological systems follow a universal structural progression: • Admissibility — physiological constraint alignment and system entry • Datum — baseline health state and biological reference • Recursive Continuation — ongoing biological regulation and feedback • Constraint Drift — pre-closure instability phase (disease progression) • Boundary Closure — termination under constraint incompatibility The analysis shows that system failure in healthcare is not anomalous, but structurally necessary once constraint drift exceeds admissible bounds. This record does not introduce new theoretical components. It applies existing Paton System constructs to a biological domain, confirming cross-domain structural consistency.
