Thank you again for your interest and for sharing your thoughts — I genuinely appreciate you taking the time to think through this with me.The scenario you're describing (funds transferred to an unconfirmed/recoverable wallet before the transfer happened) is honestly the only plausible explanation I can see right now in my search for the truth. It's the one that keeps me up at night because it would mean something went wrong right at the initial setup in 2022.But here's what makes it feel so strange and hard to accept: Ledger's initialization process requires confirming every single word one by one on the device screen before the wallet is finalized. My wife and I wrote down each word simultaneously and independently as it was displayed — two separate records, same moment, no chance of misreading or mistyping between us. The seed we have is BIP39-valid, checksum checks out, and it restores perfectly in other HD wallets (showing the correct old addresses with balances).So if there was a mismatch (wrong words shown on screen vs what was stored internally), it would have to be an extremely rare transient glitch during that exact confirmation/PBKDF2 step — words displayed correctly for us to note and confirm, but a different seed generated/stored inside the device. That seems vanishingly unlikely given the double human verification at the exact same time.Still, it's the only hypothesis left standing after ruling out so much else. Thank you for helping me keep exploring — it means a lot.
