Never heard of that. Google shows no results. Doesn't seem to exist.

Cleanup of what? What is SPX-QEC? Your draft doc links to this word-salad repo. 
I can't make sense of how this is related.

What does this even mean? There is no way to "quantum harden" a secp256k1 
keypair with different entropy, despite what some snake-oil salesmen are 
saying. A curve point is a curve point and Shor's algorithm can factor it to 
find its discrete log just as well as any other point.

Mods, this appears to be an underinformed proposal at best, AI slop/spam, or 
even phishing at worst. 

Needless to say but I'll say it anyway: Don't use this tool to generate paper 
wallet keys. The keygen code is unreadable gibberish to my eye. Output entropy 
could be compromised in a way that only the author knows, designed to steal any 
money deposited into the output keys. Don't click on links to websites you 
don't already know & trust.

DigiMancer3D, if this is not the case, please explain your proposal better and 
document your code.
