What happens when a run fails?
Failure is per account, not per run. An account the platform brakes goes to waiting and is asked again a quarter of an hour later, up to eight times: two hours of patience before anything is called a failure. A write fault is retried five times. The run finishes done, partial or failed, the mail names the accounts that did not land in the platform's own words, and Retry runs only those. A run that fails outright writes nothing.
