 Vehicle service coverage is always shown at VIN level. A vehicle may have one or more ingestion sources, but upper product views should summarize source count, online source count, last seen time, and binding status before drilling into protocol-specific diagnostics.
 
+Vehicle lists should expose a vehicle-level service status derived from binding and source coverage: identity required, no data source, offline, degraded, or healthy. Protocol tags remain attribution and troubleshooting context, not the primary status.
