I suspect that, with the "push to incoming, vet there and move to
verified" workflow, you do not need a special GPG-signed list.  You can
instead have the pusher sign the tip using the usual signed-tag mechanism,
which would sign the whole history leading to it, and have him push that
tag to the incoming together with the tip update.  You obviously do not
need nor want to move that signed tag to the final area.
