+name: Auto-promote staging → main
+
+# Fires after any of the staging-branch quality gates complete. When ALL
+# required gates are green on the same staging SHA, fast-forwards `main`
+# to that SHA automatically — closing the gap that historically let
+# features sit on staging for weeks waiting for a bulk promotion PR
+# (see molecule-core#1496 for the 1172-commit example).
+#
+# Safety model:
+# - Runs ONLY on workflow_run events for the staging branch.
+# - Requires EVERY named gate workflow to have the same head_sha and
+#   all be `conclusion == success`. If any of them is red, skipped,
+#   cancelled, or pending, we abort (stay on the current main).
+# - Uses --ff-only: refuses to advance main if main has diverged from
+#   the staging history (e.g. a hotfix landed directly on main). In
+#   that case a human resolves the fork.
+# - Writes a commit summary so the promote shows up in git log as a
+#   deliberate act, not a stealth move.
+#
+# **Initial rollout:** ship this file but leave the `enabled` input set
+# such that nothing auto-promotes until staging CI has been reliably
+# green for a few days. Toggle via repo variable `AUTO_PROMOTE_ENABLED`.
