La Profilée - The Verification Layer: On the Convergence of Formal Necessity, Empirical Instantiation, and Ex-Ante Validation

La Profilée (LP) establishes the persistence condition IR = R / (F · M · K) ≤ 1 as the structurally necessary constraint governing identity under real transformation (Paper 103). Subsequent work has established: • the admissibility regime is induced by the persistence problem itself (Paper 122) • no alternative formulation of persistence exists outside trivialisation, indeterminacy, or structural equivalence (Paper 123) • LP defines explicit and exhaustive falsification routes (Paper 124) • the condition is instantiated across structurally independent domains (Paper 118) • LP variables are functional roles admitting operationalisation without collapsing structural abstraction (Paper 119) This paper introduces the Verification Layer: a unified structure demonstrating that LP is not only formally derived and empirically recurrent, but externally verifiable under independent reconstruction and prospectively testable through ex-ante prediction. The result is not an additional argument. It is the closure of the validation space.
