Propagate Device and Intent Status Codes Across Diagnoses

Network Intent currently does not carry device-level or intent-level status codes generated in one diagnosis forward into a subsequent diagnosis within the same intent, requiring each diagnosis to independently determine its own status. This enhancement would allow a status code established in an earlier diagnosis to be referenced and reused by later diagnoses within the same intent. Customers building multi-step diagnostic logic would benefit from more consistent and accurate status reporting without needing to duplicate status determination logic across each diagnosis.
