Recorded synthetic replay
One request. One correction.
Follow a fictional purchase request from intake to a reviewed decision. The buyer’s correction changes the recommendation, and an approval of the old calculation does not carry over.
Scripted synthetic replay. Recorded from the method’s reference workflow, not live software. The buyer’s correction and decisions are part of the script: nothing detected the mistake automatically. Role names are labels, not sign-in. The handoff goes to a simulated destination—no purchasing system, supplier or purchase order is involved. The fixture is public, so it is not a blind test.
