Local Overrides does what? Problem is that the devtools are not available due to the repeated abuse of the debugger and console clear commands. The other problem is storing content on the local disk for study. I don't think devtools do that.
Local Overrides stores the files you chose to override in a folder of your choosing. Subsequent requests for that resource while devtools is open will replace the contents with your local copy.
So the idea is store it in local Overrides, find the bad anti debug code and remove it, then you get back full control in devtools.
That might be useful in some simpler cases. Lately, I've been hacking into some really hard stuff that pretty much required the use of two web browsers due to caching, garbage popups and other matters. One browser doing the debugging and the other that I could cold-start without losing any work. The proxy server makes this division of labour possible.
