+
+### Fixed — Idempotent suspension
+
+- `ProcessBilling` now skips re-suspending a team that is already suspended. Previously every billing cycle for an overdue, grace-expired team re-ran `SuspendTeam` (scale-down + orphan-pod deletion), which was wasteful and could delete pods a user legitimately created in the namespace.

 ### Fixed — Auto-recharge validation
