# .gitea/workflows/helm-release.yaml
# -------------------------------------------------------------------------
# secret-manager 用のチャート公開ワークフロー。
#
# 他リポジトリの「毎 push で無条件公開」する共通版とは異なり、この版は
# 3 つのリリース成果物を **それぞれ独立に冪等チェック** する:
#
#   1. Package Registry  ... `Chart.yaml` の version が未登録なら発行
#   2. Git タグ v<version> ... リモートに無ければ作成して push
#   3. Gitea リリース      ... 同名リリースが無ければ作成（tgz 添付）
#
# 独立チェックにしている理由: いずれかのステップだけ失敗しても、次の push で
# 不足分だけが再実行されて自己修復する（例: registry 発行は成功したがタグ
# push が権限エラーで失敗 → 次回 push でタグだけ作成される）。
# どれも不要なら全ステップが no-op（README や examples だけの変更で発火しても
# リリースは発生しない）。
