-This manifest defines the five foundational pillars of an antifragile enterprise. It is not a security framework. It is a **strategic operating philosophy** for organizations that intend to outlast their competitors, their regulators, and their own assumptions.
+This manifest defines the five foundational pillars of an antifragile enterprise. Each pillar describes both a principle and a set of concrete moves. The philosophy is platform-agnostic—these pillars apply whether your client runs Microsoft 365, Google Workspace, AWS, on-premise Linux, or a hybrid OT environment.
+
+Your job as a consultant is to translate each pillar into the specific context of the client. The language should shift (a CISO hears "Stress-to-Signal Conversion" differently than a CFO does), but the underlying logic does not.
 
 For the reasoning *why* these pillars work—drawn from natural systems, distributed networks, and emergent order—see [Spontaneous Order Principles](spontaneous-order-principles.md).
