Candidates abandoned by an unexpected error (typically storage). Their records keep the attempt key already used, so the next run replays the PSP's cached response instead of charging again.
Renewals that did not collect this run (now past_due, retry or replay scheduled).
Frozen until resolvePendingRenewal: charges resolved as "processing", and charges without a definitive answer that no replay can safely follow.
Ended this run: dunning exhausted or cancelAtPeriodEnd reached.
