Ambiguous NewMiningJob stratum-message format

[jakubtrnka]

NewMiningJob is defined here:
https://github.com/stratum-mining/sv2-spec/blob/main/05-Mining-Protocol.md#5315-newminingjob-server---client

the merkle-root is supposed to be 32-bytes array.
It is, however, declared as B32, which can easily be mistaken for a generic byte array Bytes0_32 which has a one-byte length prefix

"B32" is not defined in the section of types.
https://github.com/stratum-mining/sv2-spec/blob/main/03-Protocol-Overview.md#31-data-types-mapping

It's a question how to exactly reword the specification - Bytes type of length 32 or the U256? But in any case B0_32 is incorrect and is the reason why
SRI is not compatible with Braiins SV2 miners

Nice catch!
