The single serial DeliveryWorker is replaced by Infrastructure/Jobs: - Job rows are leased with one FindOneAndUpdate (oldest RunAt first, a two-minute lease) and a reaper returns expired leases every 30 s; - enqueueing wakes the workers, which otherwise poll every five seconds; - delivery runs eight at a time with at most two per host, so a slow or dead server holds two slots, not the queue; - a failure waits n^4 + 15 + jitter seconds (Mastodon's curve) for up to 16 attempts; a 4xx other than 408/429 is final, a 429 honours Retry-After; - RemoteInstance is a per-host circuit breaker: ten consecutive failures quarantine a host for an hour, doubling to a week, and its jobs wait without spending attempts; - a delivery is queued once per activity and inbox (unique DedupeKey), and finished jobs expire after seven days (TTL on FinishedAt). Migration _004 moves pending Delivery rows into jobs and marks them abandoned, so a rollback to the old worker cannot send them twice.
