For signing, a packet is first encoded by protobuf to the undelimited wire format. The result is a sequence of bytes, in Python stored in a str
value.
That string is passed to the electroncash.bitcoin.EC_KEY
method sign_message
:

The compressed
argument is False
if a vk_from
value starts with '04'
(indicating a compressed key?), True
otherwise.
There seem to be several specifics to the signing protocol. Some of them may be variable and need conformance.
Determine what needs conformance in the signing protocol. Document details in the protocol docs.
