Feedback is another development cycle
When reviewers request changes, update the branch and push new commits. GitHub automatically updates the pull request with the new diff.
Keep feedback traceable
Reply to comments when a decision needs explanation. After implementing a request, mention what changed and which tests verify it.
Do not optimize solely for approval
A requested change should still be evaluated against the project's architecture and requirements. If a suggestion would create a problem, explain the trade-off respectfully and propose an alternative.
