Make the expectation explicit
When acceptance criteria change, inspect related cases and remove obsolete assertions deliberately. Keep the reason for the change visible to future reviewers.
Put it into practice
Use the feature organization in AuraCheck to review a coherent set of cases. Rerun the affected journeys and inspect the new evidence before closing the work.
Try this on your next release
Choose one journey, define the expected result, and inspect the evidence from a completed run. Expand the suite after the first test is useful.
