Hi @SimonBin -- could you raise an issue please? (People from outside search in issues; PRs are details)

Thanks

1. The build is grumpy about a file .css:

https://github.com/apache/jena/actions/runs/19701807394/job/56577824838?pr=3585

2. The compare is showing 300+ files different. Could you rebase your branch to current main please?

[SimonBin]

2 -> that's odd, on https://github.com/apache/jena/pull/3585/files there are only minor changes and

$ git rebase origin/main
Current branch geoyasr is up to date.
