Partial signature entries use the map key
{0x02}|{public key}
. However, a single public key may be involved in signing multiple inputs, and the signature will differ in each one. Since the map keys are to be unique, this is a problem. I suggest the following map key instead:{0x02}|{input index}|{pubkey index}

HD derivation entries waste space by repeating the public key. I recommend using the following map key instead:
{0x03}|{input index}|{pubkey index}
, which also matches previous point.
