the best case would be to expose the same metadata the system uses to decide if we need to backfill a series (we keep a flag if we have seen an entire repo iteration or not) in the GraphQL, and add that to the condition
We can't used the solution proposed in #24226 due to weekly job pruning, but #24226 still accurately describes the bug behavior we're trying to fix.
