I was under the impression that we were safe from non-delegates, and in some cases even delegates, not having rad/sigrefs and fetching still being able to succeed.

However, according to this Zulip thread¹, a namespace with missing rad/sigrefs can occur in a failing fetch.

We should investigate this, first by checking that there is an existing test, either in the e2e.rs module, or in the commands.rs test module for this test case. If not, then we should add a case and confirm that what is going wrong here.

It could be the possibility that the peer somehow had references but no rad/sigrefs, through manual manipulation of their storage references – which may not be accounted for.
