Why it happened
In the catalog's worked example, TOVIO explains it like this. Names and values in it are illustrative.
The namespace already holds a blob of this name.
How to fix it
- Publish under a different name
- Delete the existing blob first where the surface permits it (a draft release; an admin on a published one)

✗ Blob `dist.tar.gz` already exists in this release
A published artifact or asset is never replaced. Delete it first (a draft
