01
Modeled Trace as a many-to-many link between Requirement and Artifact to support bidirectional traceability.
02
Modeled SafetyCase and SafetyCaseItem to aggregate artifacts without duplicating artifact metadata.
03
Used native erd notation with composite primary keys for junction tables.
Use when building a traceability matrix or artifact registry for safety-critical AI systems, especially where artifacts must be grouped into safety cases.
