+       create a comment. We write out an empty file to the comment path so the
+       issue-write workflow knows not to create anything.
+    2. There has never been a previous failure and the job fails - We create a
+       new comment containing the failure information and any possible premerge
+       advisor findings.
+    3. There has been a previous failure and the job passes - We update the
+       existing comment by passing its ID and a passed message to the
+       issue-write workflow.
+    4. There has been a previous failure and the job fails - We update the
+       existing comment in the same manner as above, but generate the comment
