We needed some retry behavior before launch and had no data on receiver load patterns yet. ## Decision Failed deliveries are retried exactly three times, one second apart, then reported as failed. The retry count and spacing are constants in lib/relay/delivery.rb. ## Consequences Simple and predictable; transient blips are absorbed. Receivers that are down for more than a few seconds still lose the delivery, and rapid-fire retries add load to a receiver that is already struggling. ## Alternatives rejected No retries rejected: transient network errors were the dominant failure mode in testing. Unbounded retries rejected: a permanently dead endpoint would wedge the queue.
