I did try it twice, some hours apart. And in the meanwhile, the package
defined using Guile downloads its sources and builds just fine.

It is in the manual (Search for "JSON representation"):

Not clear to me whether you can provide a source hash as part of a JSON
package definition.

Thanks & let me know if you turn up any other clues!
