SyncProcessingDeferred

Terminal: the SmartWalking API accepted the submission but did not issue a jobId (see ProcessingDeferralReason), so the SDK cannot track end-to-end processing. The data is acknowledged and will be picked up by a backend-side scheduled promotion task or the next com.advantahealth.api.smartwalking.SmartWalking.syncSteps call. Consumers may surface a "processing pending" hint and/or refresh on their own cadence.
