+// Safety/Security separation for the IACE hazard log.
+//
+// The traditional CE risk assessment (Maschinenrichtlinie / EN ISO 12100) and
+// the cybersecurity assessment (Cyber Resilience Act) are two distinct steps.
+// IACE owns the traditional, physical + functional-safety hazards; the CRA
+// module (/sdk/iace/{id}/cra) owns the native cyber/AI topics and re-examines
+// which safety functions a cyber attack can re-open (see iace-safety-bridge).
+//
+// The split is by the NATURE of the hazard, not by the component: a control
+// fault, bus failure or botched update is FUNCTIONAL safety (random/systematic
+// fault) and stays in CE — independent of whether the controller is a bought-in
+// CE-marked PLC or the manufacturer's own embedded control. Only the security
+// PROPERTIES against malicious actors (access control, firmware/update
+// integrity, SBOM, vulnerability handling, default passwords) are CRA.
+//
+// Functional-safety control categories (software_control, software_fault,
+// safety_function_failure, configuration_error, communication_failure,
+// update_failure, sensor_fault, …) therefore intentionally STAY in IACE — they
+// are the safety functions whose loss the CRA bridge re-examines.
+//
+// Enforced centrally in InitializeProject so it holds for EVERY project.
