+# The Skill Eval Report (skill-eval-report.yml) runs the deterministic holdout
+# scorer daily and is intentionally NON-BLOCKING: a regression or a scorer
+# hard-error never fails the workflow. Before this script its only output was a
+# step summary / artifact / annotation — effectively invisible. This notifier
+# makes the outcome visible WITHOUT making it blocking:

+#   outcome=regression | error -> open OR update a single `eval-health` tracking
+#                                 issue (idempotent: the same issue is rewritten
