How are they compatible if they could be using entirely different wor= d lists??


Wordlist is ne= cessary for the step [seed]->[mnemonic]. Step [mnemonic]->[bip32 root= ] doesn't need any wordlist, there's just hashing involved.
For this reason client can generate whatever mnemonic and unless all c= lients use the same process [mnemonic]->[bip32 root], the result is the = same.

Maybe I'm missing something, but shouldn't this be a client-side th= ing, not
implemented in the Trezor firmware at all?? O.o;;


Trezor generates the seed and transfor= ms it to mnemonic (which is then shown on internal display). Generating the= mnemonic outside the client-side (computer) is one of main functionality o= f Trezor.
