It merged. Who knows what changed?
The PR is merged and the checkmark is green. Ask what changed for users and everyone points back to the diff. Approval should mean someone understood the behavior.
Understand the change
AI reads the diff and the code around it, then explains what changes and where the risks are.
Review behavior in Slack
Check the explanation against what you meant to build. Ask questions in the thread before approving.
Keep the decision
