+# Publishes the arkruntime package to PyPI (pypi.org/project/arkruntime,
+# maintained by the volcengine account). Tags are created exclusively by
+# ark-hand after a sync PR lands on main, so a pushed v* tag is always a
+# reviewed release snapshot whose tree matches the internal source tree.
+#
+# The workflow_dispatch input allows re-publishing (or first-publishing)
+# an existing tag — e.g. when the PYPI_API_TOKEN secret was missing when
+# the tag was originally pushed. The workflow definition runs from the
+# ref the dispatch targets, while the build checks out the named tag.
