keyfunc mnemonic prints a child mnemonic derived from the main one with BIP-85's own mnemonic application, in English, at 12, 18 or 24 words. Its entropy is the BIP-85 entropy cut to the length the word count needs, which is what that application asks for, so it does not go through the generator the other key types read their bytes from. The BIP-85 specification's own test vectors for the application are the tests. Two pieces the derivation package already had inside one function are now named: the master key a mnemonic stands for, and the refusal of a key index that has no hardened child. Both key types call them. Model: opus-5
