1
00:00.000 --> 00:06.000
This is a local simulation: twenty arrivals per second and two workers.

2
00:06.000 --> 00:12.000
After ten seconds, backlog reaches 180 messages.

3
00:12.000 --> 00:18.000
To recover, set arrivals to zero and increase to fifty workers.

4
00:18.000 --> 00:24.000
Advance ten seconds: the queue drains and work completes.

5
00:24.000 --> 00:30.000
With permanent failures, three attempts move a message to the DLQ.
