+# Stub workflow — enables discovery of review.agent.lock.yml so that
+# `gh workflow run review.agent.lock.yml --ref <branch>` works.
+# The real workflow lives on the feature branch; --ref executes THAT version.
+# This stub is safe to leave on main — it does nothing on its own.
+#
+# Once PR #118 (feat/expert-review-workflow) merges, this stub is replaced
+# by the real compiled workflow and can be removed.
