                acl:origin <https://podpro.dev>]

Thanks for spotting this! I think maybe this patch is actually incorrect. The _:patch in the subject is fine, but why is there a blank node _:bn_wrjr7 in there? Can we change mashlib so that it uses a named node there?

CSS indeed checks this

And the spec indeed specifies this
