It looks to me that there is a new requirement in draft-ietf-cbor-cde-02 that isn’t in RFC 7049 (canonical CBOR) or RFC 8949 (Preferred Serialization and CDE). The requirement is that no value that can fit into an int64 or uint64 can be sent as a tag 3. That implies 65-bit negatives ints must be sent. It’s the new requirement that I’m bringing up, not the coexistence of int and bignum. LL
