When you initiate the tx0 in Ashigaru Terminal it displays the tx0 fee and the structure of the transaction you are about to broadcast.
After you broadcast the tx you can see in a different wallet software (or mempool[dot] space) if it indeed matched what the Ashigaru Terminal wallet said would be the fee.
If it did not match then you can do an CPFP back to your deposit account. Crisis averted.
