+# Builds a Python package with `python -m build` and uploads it to the Gitea PyPI registry with
+# twine. Intended to run only on version tags (v*), alongside python-checks, so a package is
+# never published without its tests passing.
+#
+# The caller gates this job on python-checks and on the tag ref, the same way docker-publish is
+# gated. The job itself additionally refuses to publish when the git tag does not match the
+# version declared in pyproject.toml, so a mistyped tag cannot ship the wrong version.
