Good morning Stepan, and Nadav,
Both additions seem good idea to me.
> - Sally generates the invoice with the preimage `S` (i.e. x-coordinate of this point to make it 32-bytes long)
Does this require Bob to attempt both positive and negative sign for the y-coordinate?
Alternately we can force Sally to always use a scalar such that generated point has a fixed sign (or some other property to derive the sign of the missing coordinate).
Regards,
