Bug fixes

• The ECS CloudWatch event patterns generated by the AWS > Turbot > Event Handlers stack previously ignored the AWS > ECS > Service > CMDB policy. Because that policy targets the ECS cluster rather than the region, disabling it at the region or account level had no effect and Guardrails kept forwarding service events (CreateService, DeleteService, UpdateService). The event patterns now read the effective per-cluster CMDB value, so the service events are only forwarded when at least one cluster in the region still has the CMDB enabled.
