Queue, retries and recovery
Local deterministic simulation. One step = one second; one worker = one attempt per step; three failures = DLQ. Does not measure production systems.

To recover: set arrivals to zero, increase workers and advance. Failures affect deterministic IDs; the same message fails again until the configuration changes.
