The Question Every Theory Forgot - La Profilée and the Structural Law of Persistent Identity under Transformation

Every scientific theory, every management framework, every philosophy of change operates on the same unexamined assumption: that the systems they describe continue to exist. They explain how things transform. They do not specify when transformation destroys the system itself. This paper introduces La Profilée — a formally derived structural law that closes this gap. It shows that identity under transformation is not a matter of strategy, resilience, or adaptation. It is governed by a structural condition that can be specified, measured, and violated only at the cost of collapse.
