> Issue Type: Bug

> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.24.0

> Found in a recorded "let there be chaos" run (CAMEL-26760): an experiment
> (CAMEL-26774) where the payment service is down and the dead letter channel
> fails too ({{endpoint=http:... error status=503 until=1m;
> endpoint=direct:parked error at=dlq until=1m}}) ended PASS (expect
> orders:failed<=0, 0 failed), while the report of the same run said FAIL:
> "rule r7 failed or dropped 58 sends of the dead letter channel, which handled
> them without delivering them: 58 lost".
> The dead letter channel handles a message it could not deliver
> (deadLetterHandleNewException), so it neither fails nor completes in its
> route, and no expectation on the route sees it. The report counts it as lost
> at the dead letter channel and fails; the experiment only reads its
> expectations.
> Fix: an experiment counts the messages its rules lost at the dead letter
> channel ({{lostAtDeadLetterChannel}}, per rule), and its verdict is FAIL when
> there are any, as the report's is. The journal and camel get chaos --report
> say so.
