A workflow-scope subject-KIND entry value, keyed by a bare doc id in the
bench's default resource — what a definition declaring the first-class
subject kind expects at start (applicability and document pickers key on
that kind). type defaults to 'document'; pass the subject's schema
type when a filter or projection reads it. For a plain doc.ref input,
use docRefField.
