Oh, I am glad to learn reading Bitcoin core dos that Bitcoin wallet.dat files are now HD by default This is very bullish for me finding them then Hell, if I knew what the proper sentinel is for the seed and can find a function that uses my password to get the key I can solve this with my own little conde snippet and a Linux system where I can access the block device as a file The chances are very good since a seed is only 32 bytes so even if the wallet's history db is broken that I can recover the seed and with that restore from a synced node that knows how to derive the keychain The zfs volume backup is imminently complete... Worst case scenario just moved to probably can find it with a day or two of work. Worth it, I am late paying rent and I am not gonna leave any stone unturned, nor am I going to finish this without having that seed on paper.
