AlertDelivery records one attempt to push an alert out. It links the alert via alertId and the destination via channelId, captures the result in status, and stores any failure detail in error. The sentAt timestamp marks when the delivery was attempted. These records let operators audit whether an alert actually reached its channel, diagnose failed sends, and distinguish a quiet system from one where notifications silently never arrived.
