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.
Cost Engineering · recorded workflow on fictional data
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.
