- An error test vector doesn’t specify the InvalidContributionError type
- In *DeterministicSign*, use GetXonlyPubkey instead of GetPubkey
- The key_agg_and_tweak fn doesn’t specify the return type
- In partial_sig_verify_internal, the pubkey arg should be PlainPk
- Remove unused enumerate() fn calls
- In test_sign_verify, add an additional assert statement
