+# Experimental / pre-release lane for the `develop` branch.
+#
+# This is a thin caller around the SHARED reusable workflow
+# openfga/.github/.github/workflows/release-please-prerelease.yml. The common
+# logic lives there so every SDK can onboard by copying just this file.
+#
+# It is completely separate from release-please.yml (the stable main flow):
+#   * targets the long-lived `develop` branch
+#   * only ever cuts pre-release versions (alpha/beta/rc) — enforced by the
+#     reusable workflow. Stable releases must go through main.
+#
+# Triggers:
+#   * workflow_dispatch → build a release PR for an explicit pre-release version
+#   * push to develop   → when the `release:` PR merges, tag + draft + publish
