Here's the problem. When the @latest query results in an error (as it would have for godsfood/baseconv@8514a09), the Origin information for the error does not include the Ref that failed to resolve.

When we try to -reuse that origin again, it doesn't check that Ref still fails to resolve, and so it doesn't invalidate the result as it should.
