Generic Fields (19)

These are common fields that appear across multiple namespaces. They represent attributes that are inherited or reused from a global schema— things like timestamps, unique identifiers, user IDs, or status codes that every namespace needs. By sharing these fields, we ensure consistency and make it easy to run cross-namespace searches and reports.
