DriverInstanceDiagnostics.Name carries the string driver-instance id (what /hosts, telemetry and the artifact key on) and DriverInstanceId the DB row Guid; the wire record has no slot for the authored display name. The write-cap test asserts entry order per slot pair instead of completion order of two concurrent writes. Refs #731 Claude-Session: https://claude.ai/code/session_01Ub9hGmYLQvn9XETzw7CMsT
