You'll notice
Artifact headers now correctly say 'File' for files and 'Artifact' for artifacts
What
The label shown above an artifact now reads "File: " when the item is a file, and "Artifact: " otherwise. Previously it always said "Artifact" regardless of kind, and the underlying code referenced an undefined variable, meaning the distinction never actually worked.
Why
This fixes a bug so that files and artifacts are now labeled correctly and distinguishably in their headers.
