+# Order Module — Manual Review Checklist
+
+High-risk module: order lifecycle changes require human confirmation.
+
+- [ ] State machine transitions are atomic (`WHERE status = ?` updates)
+- [ ] Cancellation / timeout / expiry paths complete all side effects
+- [ ] Order idempotency key prevents duplicate order creation
+- [ ] Price/lock snapshot captured at order time, not at payment time
+- [ ] Partial fulfillment / split-shipment handled
+- [ ] Negative or inconsistent totals impossible
+- [ ] Concurrent edits (cart + order) do not corrupt state
+- [ ] Audit trail: every status change logged with reason
