Re: very difficult question about real verify the signature
an indirect answer:
I have quickly double checked your data with some of my scripts. The replacement of the transaction and the created double hash value seems to be correct. I am not understanding the pubkey you use in the function main().
When I am using the pubkey of the pubkey script you extracted (of course without the length field and without hex "ac" at the end), then it runs ok.

very thinks your work , so you make me know the calculate hash is true、the public key is true, so the real problem is my go code about verify the signature!!
very thinks your patient， Grin Grin
but i also don't konw where my go code fault
