What would prove the design wrong?

What would prove the design wrong? They exercise the route the design already expects. Record failure, uncertainty and owner response. #EricFieldNotes
Full written post / accessible read
A model loop can make an architecture sound coherent from every angle. My signoff question is simpler: what observation would force us to abandon it? If nobody can answer, more polished debate is producing persuasion, not engineering evidence.
Suppose a queue worker passes normal delivery tests. Those cannot tell you whether a network partition duplicates an effect or whether recovery exceeds the promised window. The relevant experiment must cross a boundary the design says it handles.
Before running the fault, write the expected operation count, final state and maximum recovery time. Then inject a safe partition in a disposable environment and read the actual downstream record. A test added after seeing the result can explain anything; a prior prediction risks being wrong.
If the observed state violates the threshold, stop the rollout and revise the assumption. Keep that fault in the protected harness for later agents. Do this because engineering is not being right in a model debate; it is letting the system's behavior overrule your favorite answer.
