+# Updated to ensure "Run Go Tests" runs for pull requests as expected.
+# Key fix: the test_go job previously required github.event.review.state == 'approved'
+# which only exists on pull_request_review events. That prevented the job from
+# running for regular pull_request events (opened / synchronize / reopened).
+# New logic: run tests for pull_request events, and also allow running when a
+# pull_request_review is submitted with state == 'approved'.
