"description": "`age_check.completed`: a result is in. `age_check.failed`: a presentation verified but gave no readable answer, because it did not disclose the claim. `age_check.expired`: the request lifetime elapsed with no answer (sandbox checks complete by themselves first). `age_check.attempt_failed`: a presentation failed verification, over either transport, or a wallet sent an error response such as a decline, and the check stays pending, so it is not terminal: the check still ends in one of the other three, announced to an endpoint subscribed to it. It is a notice, not a log: at most one waits unsent per check, one whose check has ended before it is picked up is dropped, and it does not follow the terminal event, except rarely when a delivery is interrupted while being sent. Read the check for `failedAttempts` and `lastFailureCodes`, which count every attempt. An endpoint saved before this event existed stored the events known then, so add it to receive it.\n"
