I looked at the environment, all dependencies are updated as recent as they would go. (Not stale, then?)

Btw, there is no `test/Project.toml`. Shouldn’t this test be by-passed then?

“Stale deps” indicates that these are not loaded with the package. It’s not about version numbers, but about whether the dependencies are being used at all.

So the solution then is to remove unused deps, I guess?

Yes, in most cases, such unused dependencies may be safely removed. This should solve the Aqua issue.
