Build me a Python command line tool that can download YouTube and Instagram links reliably even from cloud servers where normal download tools get blocked.

I want it to try a few different methods in order, automatically fall back if one fails, and keep track of what worked best over time. It should have commands to check the environment, see which methods are healthy, start the optional proof of origin server, and download one or more links. When I ask for JSON, it should return clean machine readable output with the full attempt history, the final file path, and basic file verification so it can reject bad or broken downloads.

Please make it smart enough to handle audio only, quality choices like 720 or max, and save files to a chosen folder. Use real checks so it can tell when a method is blocked and try the next one. If you need current docs for any tools it depends on, look them up online and make it work end to end.
