La Profilée — State of the Theory

La Profilée (LP) establishes a single structural constraint governing persistence under real transformation: IR = R / (F · I · C) ≤ 1. Derived from two minimal assumptions — determinability and real transformation — the condition is domain-neutral. It does not describe how systems evolve. It constrains which evolutions are compatible with persistent identity. This paper presents the current state of the theory. It distinguishes strictly between the persistence condition itself, its necessary structural consequences, its extensions, and its applications. The operational diagnostic layer — LP becoming — remains proprietary.
