[CAMEL-26789](https://issues.apache.org/jira/browse/CAMEL-26789): a bug in the experiments of CAMEL-26774 (#29480). I found it in a recorded "let there be chaos" run (CAMEL-26760). **What happened.** The AI ran this experiment against the chaos example shop, with the payment service down and the dead letter channel failing too: ``` endpoint=http://localhost:8080/payment error status=503 until=1m; endpoint=direct:parked error at=dlq until=1m expect=orders:failed<=0 ``` The experiment passed (0 failed). The report of the same run said: ``` FAIL: rule r9 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 the message neither fails nor completes in its route, and no expectation on the route can see it. The report counts it as lost at the dead letter channel and fails. The experiment only read its expectations, so it passed. **Fix** - An experiment counts the messages its rules lost at the dead letter channel: `lostAtDeadLetterChannel`, plus `lostAtDeadLetterChannelPerRule`. - Its verdict is FAIL when there are any, as the report's verdict is. - The journal text and `camel get chaos --report` show "lost at the dead letter channel: 58 messages, handled there without being delivered". **Tests** - `ChaosExperimentTest.messagesLostAtTheDeadLetterChannelFailTheExperiment`: a route with a dead letter channel, the service and the dead letter channel both failing. Billing has 0 failed, and the experiment is still FAIL with 3 lost. - `ListChaosTest` checks the new line. - camel-chaos: 826 green. Independent of the open chaos stack (#29498, #29499, #29501): it changes code that is already on main. _Claude Code on behalf of davsclaus_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_012nJsFsjqqFiwroeHRWaKbS -- This is an automated message from the Apache Git Service.
