 ## 3. Verify
 
 - [x] 3.1 Open a PR with a passing test suite and confirm a comment is created showing correct counts.
-- [ ] 3.2 Push a commit that introduces a failing test to the same PR and confirm the existing comment is updated (not duplicated) with the failure listed and correct counts.
+- [ ] 3.2 Push a commit that introduces a failing test to the same PR and confirm the existing comment is updated (not duplicated) with the failure listed and correct counts.

 - [ ] 3.3 Confirm a push to `main` and a manual `workflow_dispatch` run do not attempt to post a comment.
