This record aggregates the complete CP27 — SYSTÈME PARADOXE corpus, composed of 27 interrelated PDF documents forming a coherent, auditable and non-clinical cognitive framework.The corpus includes integrative matrices, operational protocols, audit standards, comparative governance tables, responsibility addenda, and stabilization mechanisms designed for human–AI interaction under strict constraints of non-decision, interruptibility, traceability, and human responsibility.This work does not claim normative authority, certification, or legal replacement of existing international standards (e.g. regulatory, ethical, or management frameworks).It provides an explicit, auditable operational layer intended to complement such standards by addressing practical gaps related to stop conditions, invalidation logic, cognitive overload prevention, and preservation of human sovereignty in AI-assisted contexts.
