+      - name: Sweep orphan tunnels
+        # Stale-org cleanup deletes the org (which cascades to tunnel
+        # delete inside the CP). But when that cascade fails partway —
+        # CP transient 5xx after the org row is deleted but before the
+        # CF tunnel delete completes — the tunnel persists with no
+        # matching org row. The reconciler in internal/sweep flags this
+        # as `cf_tunnel kind=orphan`, but nothing automatically reaps it.
+        #
+        # `/cp/admin/orphan-tunnels/cleanup` is the operator-triggered
+        # reaper. Calling it here at the end of every sweep tick
+        # converges the staging CF account to clean even when CP
+        # cascades half-fail.
+        #
+        # PR #492 made the underlying DeleteTunnel actually check
+        # status — pre-fix it silent-succeeded on CF code 1022
+        # ("active connections"), so this step would have been a no-op
+        # against stuck connectors. Post-fix the cleanup invokes
+        # CleanupTunnelConnections + retry, which actually clears the
+        # 1022 case. (#2987)
+        #
+        # Best-effort. Failure here doesn't fail the workflow — next
+        # tick re-attempts. Errors flow to step output for ops review.
