This record presents a Tier-7 domain instantiation of the canonical recursive lifecycle within the Paton System. The paper demonstrates that financial market behaviour follows a universal structural progression: • Admissibility — constraint alignment and system entry • Datum — price formation as shared reference • Recursive Continuation — iterative relational dynamics • Constraint Drift — pre-closure instability phase • Boundary Closure — termination under constraint incompatibility The analysis shows that financial collapse 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 real-world domain, confirming cross-domain structural consistency. Paton System
